DETAILED DESCRIPTION

The present disclosure is further described in detail below through specific embodiments in conjunction with the accompanying drawings. In different embodiments, similar components adopt associated similar component labels. In the following embodiments, many details are described to enable a better understanding of the present disclosure. However, those skilled in the art can easily recognize that some features may be omitted in different cases, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present disclosure are not shown or described in the specification. This is to prevent the core part of the present disclosure from being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, as they can fully understand the relevant operations based on the descriptions in the specification and the general technical knowledge in the field.

Furthermore, the described features, operations, or characteristics may be combined in any suitable manner to form various embodiments. In addition, the steps or actions in the method description may also be exchanged or adjusted in a manner obvious to those skilled in the art. Accordingly, the various sequences in the specification and accompanying drawings are for the purpose of clarity in describing certain embodiments and are not meant to be required sequences unless otherwise indicated in which a certain sequence must be followed.

The serial numbers assigned to components in the specification, such as “first” and “second,” are used herein only to distinguish the described objects, and do not have any order or technical meaning. The terms “connected” and “coupled” mentioned in the present disclosure include direct and indirect connections (coupling) unless otherwise specified.

It should be noted that the terms used herein are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present disclosure. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise, and it should also be understood that when the terms “comprising” and/or “including” are used in the specification, they indicate the presence of features, steps, operations, devices, components, and/or combinations thereof.

In some embodiments, an atomization device is provided, and the atomization device is configured to heat a liquid-like atomization substrate (that is, an atomizing liquid, which generally includes one or more selected from the group consisting of essences, fragrances, propylene glycol (PG) and/or vegetable glycerin (VG), and active substances, where the active substance generally refers to a component that has a specific function or produces a physiological/sensory effect on the user, such as phenol and nicotine) to form an inhalable aerosol. The atomization device is further provided with an airflow sensor (such as microphone) that can start heating by suction. After the user sucks, the airflow sensor will sense the change in air flow, which in turn triggers the atomizing core to start heating the atomization substrate. This achieves a seamless start-of-heating experience, replacing the step of button-activated heating and resulting in a better user experience.

In some example technologies, the airflow sensor is disposed below the liquid storage cavity. During storage, transportation, and use of the atomization device, the liquid storage cavity is always located above the airflow sensor. According to the principle of liquid flow, once a liquid leakage occurs, the liquid will directly flow to the airflow sensor, which in turn causes a short circuit in the circuit of the airflow sensor, or causes a false activation of the airflow sensor. When a false activation of the airflow sensor occurs, it will output voltage to the heating component. The heating component working for a long time will generate high temperature, which will burn out parts such as the plastic wrapping on the outer layer, and in severe cases, may cause a fire.

The atomization device in the present disclosure improves and adjusts the installation position of the airflow sensor, and the airflow sensor is arranged at a position higher than the liquid storage cavity, so that the airflow sensor is always located above the bottom portion of the liquid storage cavity in the process of storage, transportation, and use of the atomization device. If the liquid storage cavity leaks or condensate is generated during suction, the leaked liquid and condensate will flow downward due to gravity and will not flow to the airflow sensor located above. This ensures that the leaked liquid and condensate do not enter the airflow sensor, do not damage the airflow sensor, and do not cause a false activation of the airflow sensor. In addition, the airflow sensor is disposed at an upper position, so that a detection path of the airflow sensor can be shortened, feedback time period of the airflow sensor can be shortened, sensitivity of the airflow sensor can be improved, and detection accuracy of the airflow sensor can be improved.

Referring to FIG. 1 to FIG. 3 and FIG. 6 to FIG. 8, embodiments of the present disclosure provide an atomization device 1000, and the atomization device 1000 may be an electronic atomization device. The atomization device 1000 mainly includes a housing 1 and an airflow sensor 2.

The housing 1 may be composed of a plurality of housing components, for example, a lower end of the housing 1 is provided with a detachable cover plate to realize battery replacement and later maintenance. Alternatively, the housing 1 may be of an integrated structure, the housing 1 is of a non-detachable structure, and the entire atomization device may be a single-use product, or the housing 1 is provided with an oil injection port, so that the atomization substrate can be supplemented.

Referring to FIG. 1, the housing 1 has a first direction and a second direction, and the first direction is perpendicular to the second direction. Taking the direction shown in the figure as an example, the first direction may be defined as an up-down direction, and the second direction may be defined as a left-right direction. When the atomization device 1000 is in a state of transportation or storage, the housing 1 is generally placed vertically. In this orientation, the up-down direction of the housing 1 is parallel to the vertical direction, and the left-right direction of the housing 1 is parallel to the horizontal direction. When the user is using it, most of the atomization substrates are also in a vertical or vertically inclined state.

The housing 1 is internally provided with a liquid storage cavity 11, an atomizing air passage 12, and a detection air passage 13. The liquid storage cavity 11, the atomizing air passage 12, and the detection air passage 13 are separated by structures such as partition plates and mounting members in the housing 1. liquid storage cavity 11 is configured to store the liquid atomization substrate, and is in communication with the atomizing air passage 12. Specifically, a lower end of the liquid storage cavity 11 may be provided with a liquid outlet hole, and the atomizing air passage 12 may be provided with a first connection hole 121. The liquid inlet passage may be provided between the liquid outlet hole of the liquid storage cavity 11 and the first connection hole 121 of the atomizing air passage 12, or the liquid outlet hole of the liquid storage cavity 11 is in direct communication with the first connection hole 121 of the atomizing air passage 12. The atomization substrate in the liquid storage cavity 11 may enter the atomizing air passage 12 through the liquid outlet hole and the first connection hole 121 of the atomizing air passage 12.

An atomizing core 3 is further mounted in the atomizing air passage 12. The atomizing core 3 has a liquid inlet hole 302, and in the up-down direction, the first connection hole 121 is aligned and in communication with the liquid inlet hole 302, so that the atomization substrate in the liquid storage cavity 11 enters the atomizing core 3 through the first connection hole 121.

In some embodiments, the atomizing core 3 may include a heating component 31, and the heating component 31 may be a metal heating structure. The heating component 31 is configured to convert electric energy into heat energy, to heat the atomization substrate (atomizing liquid).

In some embodiments, the atomizing core 3 may further include an atomization base. The heating component 31 is in contact connection with the atomization base. The atomization substrate entering the atomizing core 3 is adsorbed into the atomization base, the heating component 31 heats the atomization substrate adsorbed in the atomization substrate to form an inhalable aerosol, and the aerosol is discharged along the atomizing air passage 12 for the user to inhale.

The atomizing core 3 may be mounted below the liquid storage cavity 11, so that the atomization substrate in the liquid storage cavity 11 may flow into the atomizing core 3 under the action of gravity.

Specifically, the liquid storage cavity 11 is located on a side of the heating component 31 close to the mouthpiece mounting position 14A, and is configured to supply the atomization substrate to the heating component 31.

The housing 1 further includes a mouthpiece mounting position 14A, and the mouthpiece mounting position 14A is arranged on an end (upper end) along the first direction. The mouthpiece mounting position 14A may be understood as a position at which the housing 1 is connected to the mouthpiece 14, or may be understood as a position at which the mouthpiece 14 is mounted on the housing 1. That is, the housing 1 may have the mouthpiece 14, or may be connected to the housing 1 by installing the mouthpiece 14.

In some embodiments, the housing 1 having the mouthpiece 14 is taken as an example for description, as shown in FIG. 1. In some other embodiments, the housing 1 may not be provided with the mouthpiece 14, as shown in FIG. 7.

Specifically, the mouthpiece 14 is in communication with the atomizing air passage 12, and the housing 1 is further provided with an air inlet 1231, as shown in FIG. 6. The atomizing air passage 12 is in communication with the air inlet 1231, and the air may enter the atomizing air passage 12 in the housing 1 from the air inlet 1231 and be discharged from the mouthpiece 14 after passing through the atomizing core 3. The user can suck the aerosol formed by heating the atomizing core 3 through the mouthpiece 14.

The detection air passage 13 is in communication with the atomizing air passage 12. An airflow sensor 2 is disposed in the housing 1, and the airflow sensor 2 is configured to detect an air pressure change in the detection air passage 13. In some embodiments, the airflow sensor 2 may be disposed in the detection air passage 13 or on an end of the detection air passage 13, and an side or an end of the airflow sensor 2 away from the detection air passage 13 may be in communication with the atmosphere.

In some embodiments, the atomization device 1000 further includes components such as a circuit board 4 and a battery 5. The airflow sensor 2 is electrically connected to the circuit board 4. The circuit board 4 is electrically connected to the atomizing core 3 and a heating body of the battery 5, the battery 5 supplies power to the entire atomization device 1000, and the circuit board 4 is configured to control heating of the atomizing core 3. When the user sucks through the mouthpiece 14, air enters the atomizing air passage 12 in the housing 1 from the air inlet 1231 of the housing 1, and is discharged from the mouthpiece 14 after passing through the atomizing core 3. During the flow of the air in the atomizing air passage 12, the air pressure in the detection air passage 13 is driven to change, and the airflow sensor 2 can detect the air pressure change and generate a corresponding trigger signal. The circuit board 4 controls the heating element of the atomizing core 3 to start heating based on the trigger signal generated by the airflow sensor 2, thereby finally realizing that the user's suction action directly triggers the atomizing core 3 to start heating.

In some embodiments, the atomizing air passage 12 is provided with a second connection hole 122, and an end of the detection air passage 13 is in communication with the second connection hole 122 of the atomizing air passage 12. The detection path of the airflow sensor 2 includes the detection air passage 13 and a part of the atomizing air passage 12 from the second connection hole 122 to the mouthpiece 14. The airflow sensor 2 is disposed at an upper position, so that a distance between the airflow sensor 2 and the mouthpiece 14 can be shortened, that is, a detection path of the airflow sensor 2 is shortened, so that when a user performs suction, the feedback time period of the airflow sensor 2 is shortened, and sensitivity of the airflow sensor 2 is improved.

Referring to FIG. 1, the liquid storage cavity 11 includes a top portion 101 and a bottom portion 102 arranged along a first direction (i.e., the up-down direction). In the up-down direction of the housing 1, the airflow sensor 2 is closer to the mouthpiece mounting position 14A than the bottom portion 102 of the liquid storage cavity 11, that is, the mounting position of the airflow sensor 2 in the housing 1 is higher than the bottom portion 102 of the liquid storage cavity 11. In this way, during storage, transportation, and use of the atomization device 1000, the airflow sensor 2 is always located above the bottom portion of the liquid storage cavity 11. If the liquid storage cavity 11 leaks or condensate is generated during suction, the leaked liquid and condensate will flow downward due to gravity and will not flow to the airflow sensor 2 located above. This ensures that the leaked liquid and condensate do not enter the airflow sensor 2, do not damage the airflow sensor 2, and do not cause a false activation of the airflow sensor 2. In addition, the airflow sensor 2 is disposed at an upper position, so that a detection path of the airflow sensor 2 can be shortened, feedback time period of the airflow sensor 2 can be shortened, sensitivity of the airflow sensor 2 can be improved, and detection accuracy of the airflow sensor 2 can be improved.

In some embodiments, the liquid outlet of the liquid storage cavity 11 may be located at the bottom portion 102 of the liquid storage cavity 11, and the mounting position of the airflow sensor 2 in the housing 1 may be higher than the liquid outlet.

The airflow sensor 2 is closer to the mouthpiece 14 than the bottom portion 102 of the liquid storage cavity 11. The detection air passage 13 is connected to a section of the atomizing air passage 12 for discharging aerosol. When the liquid storage cavity 11 leaks, the leaked liquid flows into the atomizing core 3 under the action of gravity, the leaked liquid overflowing after the atomizing core 3 is full will flow down along the atomizing air passage 12, and the airflow sensor 2 located at the upper end can prevent the leaked liquid from flowing in.

In some embodiments, in the up-down direction of the housing 1, the airflow sensor 2 is closer to the mouthpiece 14 than the top portion 101 of the liquid storage cavity 11, that is, the mounting position of the airflow sensor 2 in the housing 1 is higher than the top portion 101 of the liquid storage cavity 11. That is, the entire airflow sensor 2 is higher than the liquid storage cavity 11, and there is a larger height difference between the airflow sensor 2 and the liquid outlet hole at the bottom portion of the liquid storage cavity 11, which can further prevent the leaked liquid from entering the airflow sensor 2. Similarly, the condensate can be further prevented from entering the airflow sensor 2. Even when the atomization device 1000 is in an inclined state, it is difficult for the leaked liquid and condensate to enter the airflow sensor 2. Moreover, the detection path of the airflow sensor 2 can be further shortened, the feedback time period of the airflow sensor 2 can be further shortened, the sensitivity of the airflow sensor 2 can be further improved, and the detection accuracy of the airflow sensor 2 can be further improved.

In the up-down direction of the atomization device 1000, the installation position of the airflow sensor 2 is higher than the top portion 101 of the liquid storage cavity 11, so that the airflow sensor 2 is always located above the bottom portion of the liquid storage cavity 11 in the process of storage, transportation, and use of the atomization device 1000. If the liquid storage cavity 11 leaks or condensate is generated during suction, the leaked liquid and condensate will flow downward due to gravity and will not flow to the airflow sensor 2 located above. This ensures that the leaked liquid and condensate do not enter the airflow sensor 2, do not damage the airflow sensor 2, and do not cause a false activation of the airflow sensor 2. In addition, the airflow sensor 2 is disposed at an upper position, so that a detection path of the airflow sensor 2 can be shortened, feedback time period of the airflow sensor 2 can be shortened, sensitivity of the airflow sensor 2 can be improved, and detection accuracy of the airflow sensor 2 can be improved.

In other embodiments, in the up-down direction of the housing 1, the mounting position of the airflow sensor 2 in the housing 1 is higher than other positions other than the bottom portion 102 of the liquid storage cavity 11, which can also play a role in preventing the leaked liquid from entering the airflow sensor 2. For example, the mounting position of the airflow sensor 2 in the housing 1 is located in the middle of the liquid storage cavity 11. At this position, the mounting position of the airflow sensor 2 is still higher than the bottom portion of the liquid storage cavity 11, which can effectively prevent the leaked liquid and condensate from entering the airflow sensor 2.

Referring to FIG. 1, in some embodiments, in the up-down direction of the housing 1, the second connection hole 122 is closer to the mouthpiece 14 than the first connection hole 121, that is, the position of the second connection hole 122 in the atomizing air passage 12 is higher than the position of the first connection hole 121 in the atomizing air passage 12. Correspondingly, in some embodiments, the second connection hole 122 is closer to the mouthpiece 14 than the atomizing core 3.

After the liquid storage cavity 11 leaks, the leaked liquid will flow into the atomizing air passage 12 through the first connection hole 121. When the position of the second connection hole 122 in the atomizing air passage 12 is higher than the position of the first connection hole 121 in the atomizing air passage 12, the leaked liquid flowing into the atomizing air passage 12 flows downward along the atomizing air passage 12 under the action of gravity, and does not flow into the second connection hole 122, that is, does not flow into the detection air passage 13, and does not enter the airflow sensor 2.

There is a sufficient height difference between the second connection hole 122 in the atomizing air passage 12 and the first connection hole 121, and the atomizing air passage 12 below the second connection hole 122 can form a liquid storage space with a larger volume, so that even if the air inlet 1231 of the atomizing air passage 12 is blocked, the liquid is stored in the atomizing air passage 12 below the second connection hole 122 without entering the detection air passage 13, thereby not affecting the airflow sensor 2.

Referring to FIG. 1, in some embodiments, in the left-right direction (that is, the second direction) of the housing 1, a first mounting cavity 1a and a second mounting cavity 1b are disposed in the housing 1, and the first mounting cavity 1a and the second mounting cavity 1b are separated by a mounting plate structure in the housing 1. The first mounting cavity 1a and the second mounting cavity 1b may be configured as relatively independent structures, that is, most parts of the first mounting cavity 1a and the second mounting cavity 1b are mostly separated from each other, while being partially in communication in a small region.

The first mounting cavity 1a is located at the left side in the housing 1, and the second mounting cavity 1b is located at the right side in the housing 1. In some embodiments, structures or components such as the liquid storage cavity 11, the atomizing air passage 12, the atomizing core 3, and the circuit board 4 may be located in the first mounting cavity 1a, and structures or components such as the detection air passage 13, the airflow sensor 2, and the battery 5 may be located in the second mounting cavity 1b.

The liquid storage cavity 11 and the airflow sensor 2 are respectively located in different regions in the left-right direction inside the housing 1, so that the liquid storage cavity 11 and the airflow sensor 2 are staggered. In this way, the airflow sensor 2 can further avoid the leakage of the liquid storage cavity 11, thereby improving the safety of the airflow sensor 2 and preventing false activation.

In other embodiments, the liquid storage cavity 11 and the airflow sensor 2 may be staggered in other directions. For example, the housing 1 further has a front-rear direction, and the front-rear direction is perpendicular to the up-down direction and the left-right direction. The liquid storage cavity 11 and the airflow sensor 2 are staggered in the front-rear direction, so that the airflow sensor 2 can be protected from the leaked liquid from the liquid storage cavity 11, thereby improving the safety of the airflow sensor 2 and preventing false activation.

Referring to FIG. 2 and FIG. 3, in some embodiments, the junction between the atomizing air passage 12 and the detection air passage 13, that is, at the second connection hole 122 of the atomizing air passage 12, the atomizing air passage 12 is distributed in the up-down direction, the detection air passage 13 is distributed in the left-right direction, and the atomizing air passage 12 and the detection air passage 13 are arranged at an angle at the junction. For example, the atomizing air passage 12 and the detection air passage 13 are arranged vertically at the junction to form a T-shaped layout. Therefore, even if after the leaked liquid from the liquid storage cavity 11 flows into the atomizing air passage 12, it is difficult to enter the detection air passage 13. Moreover, even if the condensate is generated at the mouthpiece 14, the condensate will be discharged from the atomization device 1000 along the vertical atomizing air passage 12 without entering the detection air passage 13, thereby further protecting the airflow sensor 2.

It can be understood that the present disclosure is not limited to a distribution manner in which the atomizing air passage 12 is distributed in the up-down direction. In other embodiments, as shown in FIG. 7, the atomizing air passage 12 may further include both a part distributed in the up-down direction and a part distributed in the left-right direction.

In other embodiments, the atomizing air passage 12 and the detection air passage 13 may be arranged at other angles at the junction. For example, the atomizing air passage 12 and the detection air passage 13 are arranged at an acute angle at the junction, and the opening of the acute angle faces upward, and the atomizing air passage 12 and the detection air passage 13 are specifically arranged at an angle of 30° or 60° at the junction. In this way, the detection air passage 13 extends in an inclined upward direction relative to the atomizing air passage 12, so that after the leaked liquid from the liquid storage cavity 11 flows into the atomizing air passage 12, it is difficult to enter the detection air passage 13. Moreover, even if the condensate is generated at the mouthpiece 14, the condensate will be discharged from the atomization device 1000 along the vertical atomizing air passage 12 without entering the detection air passage 13, thereby further protecting the airflow sensor 2.

In other embodiments, the junction between the atomizing air passage 12 and the detection air passage 13 may form a Y-shaped layout, and the detection air passage 13 extends in an inclined upward direction at the junction between the atomizing air passage 12 and the detection air passage 13, that is, the detection air passage 13 extends in an inclined upward direction at the second connection hole 122 of the atomizing air passage 12. In this way, it is difficult for the leaked liquid and the condensate to enter the detection air passage 13, thereby further protecting the airflow sensor 2. The detection air passage 13 arranged obliquely may prevent the leaked liquid and the condensate from flowing toward the airflow sensor 2, and even if the leaked liquid and the condensate enter the detection air passage 13, the leaked liquid and the condensate may flow toward the atomizing air passage 12 under the action of gravity, and may not flow upward into the airflow sensor 2, thereby further protecting the airflow sensor 2.

Referring to FIG. 1, in some embodiments, in the up-down direction of the housing 1, the airflow sensor 2 is higher than the second connection hole 122 of the atomizing air passage 12. For example, the detection air passage 13 is arranged along the left-right direction. The second connection hole 122 is located at an end of the detection air passage 13, the airflow sensor 2 is located at the other end of the detection air passage 13, and the end of the detection air passage 13 connected to the airflow sensor 2 is provided as an L-shaped structure, so that the airflow sensor 2 is mounted above an end of the airflow sensor 2, and the airflow sensor 2 is mounted upside down. In this way, even if the leaked liquid and the condensate enter the airflow sensor 2, it is difficult for the leaked liquid and the condensate to enter the airflow sensor 2 located above, thereby further protecting the airflow sensor 2.

In some embodiments, the detection air passage 13 is provided as a bent passage to form a labyrinth structure, and the labyrinth structure has a plurality of bent portions, which can effectively prevent the leaked liquid and condensate from flowing toward the airflow sensor 2.

For example, referring to FIG. 3, the detection air passage 13 is configured as a bent passage with a structure similar to a U-shape, and the middle of the U-shape forms a protruding structure 131. The protruding structure 131 can prevent the leaked liquid and condensate from flowing toward the airflow sensor 2, thereby further protecting the airflow sensor 2.

The detection air passage 13 may also be configured as another bent passage, for example, the detection air passage 13 is configured as a bent passage in an L-shape. The second connection hole 122 is connected to an end of a horizontal section of the bent passage in the L-shape, and the airflow sensor 2 is connected to the other end of a vertical section of the bent passage in the L-shape. The vertical channel in the L-shaped detection air passage 13 can prevent the leaked liquid and condensate from flowing toward the airflow sensor 2, thereby further protecting the airflow sensor 2.

Referring to FIG. 4, in some embodiments, one or more barriers 132 may be provided in the detection air passage 13. The barrier 132 may be a protruding structure 131 shown in FIG. 3 in the detection air passage 13, or a structure such as a partition plate mounted in the detection air passage 13. The lower end of the barrier 132 is connected to the detection air passage 13 in a sealed manner for blocking the leaked liquid and condensate. There is a gap between the upper end of the barrier 132 and the detection air passage 13 to ensure the unobstructed air flow of the detection air passage 13. The barrier 132 can prevent the leaked liquid and condensate from flowing toward the airflow sensor 2, thereby further protecting the airflow sensor 2.

Referring to FIG. 5, in some embodiments, a waterproof and breathable film 133 may be provided in the detection air passage 13, and the waterproof and breathable film 133 has the functions of ventilation and liquid isolation, that is, has the functions of the unobstructed air flow of the detection air passage 13. In addition, the leaked liquid and condensate may be prevented from entering the airflow sensor 2 to further protect the airflow sensor 2.

The design of the air passage structure inside the electronic atomization device will directly affect the function of the device and the user experience. In some embodiments, the atomizing air passage 12 in the atomization device is generally configured as a bottom straight-through layout. The air inlet passage is directly arranged right below or laterally below the heating component 31, and the airflow enters from the bottom of the atomization device, flows through gaps between components in the device, and takes away and discharges the aerosol generated by the heating component 31 through the air inlet passage.

In actual use, the device is prone to the phenomenon of liquid leakage or condensate backflow in the liquid storage cavity, and due to the low position of the atomizing air passage, the liquid is prone to flow downward and accumulate along the air passage under the action of gravity, and finally the air passage hole is blocked, resulting in increased suction resistance or even complete failure. In addition, if the leaked liquid flows into the circuit board, a short circuit risk may be further caused.

Therefore, regardless of whether the air inlet passage is arranged directly below or under the side of the heating component, once the atomizing liquid leaks or the condensed atomizing liquid flows back, the atomizing liquid flows downward along the air passage under the action of gravity, and accumulates at a low point, which eventually causes the air passage to be blocked, resulting in an increased suction resistance or even complete failure. In addition, if the atomizing liquid flows into the circuit board 4, the risk of the short circuit of the device may be further caused.

In view of the foregoing defects, in some embodiments of the present disclosure, referring to FIG. 7, a buffer cavity 124 is disposed on a side of the heating component 31 away from the mouthpiece mounting position 14A, so that the heating component 31 can be used to buffer aerosol and can also be used to buffer leaked or condensed backflow atomizing liquid. The air inlet 1231 is arranged between the buffer cavity 124 and the mouthpiece mounting position 14A. This configuration ensures that when the atomizer 100 is in use with the mouthpiece mounting position 14A facing upward, the air inlet 1231 is located above the buffer cavity 124. As a result, the atomizing liquid needs to completely fill the buffer cavity 124 before it blocks the air inlet 1231. Since a large amount of liquid leakage occurs rarely in actual use, the cooperation of the air inlet 1231 and the buffer cavity 124 helps to improve the problem that the atomizing air passage 12 is easily blocked by leaked liquid, which is beneficial to improve the reliability of the air passage structure. The above improvements are described below through specific embodiments.

Specifically, referring to FIG. 6 and FIG. 7, the atomization device 1000 may include an atomizer 100. The atomizer 100 may include a housing 1, a heating component 31, a buffer cavity 124, an air inlet passage 123, and a discharge passage 125. The housing 1 extends in a first direction. An end of the housing 1 along the first direction is provided with a mouthpiece mounting position 14A. The heating component 31 is disposed in the housing 1 and is configured to heat the atomizing liquid to generate an aerosol. The buffer cavity 124 is disposed on a side of the heating component 31 away from the mouthpiece mounting position 14A, and is configured to buffer the aerosol generated by the heating component 31. The air inlet passage 123 and the discharge passage 125 are both in communication with the buffer cavity 124, and the buffer cavity 124 is located between the air inlet passage 123 and the discharge passage 125 to jointly form the atomizing air passage 13. The air inlet passage 123 is provided with an air inlet 1231 in communication with the exterior of the housing 1, and the air inlet 1231 is located between the buffer cavity 124 and the mouthpiece mounting position 14A in the first direction, so as to prevent the atomizing liquid from blocking the air inlet 1231 prior to the complete filling of the buffer cavity 124 when the atomizer 100 is in the state with the mouthpiece mounting position 14A facing upward.

The housing 1 serves as the main structural member defining the external contour of the atomizer 100. Referring to FIG. 6, for ease of understanding, the first direction may be conceptualized as the vertical (height) direction of the atomizer 100 from the perspective shown in the figure.

In some embodiments, as shown in FIG. 7, an example in which the housing 1 is not provided with the mouthpiece 14 is used for description.

Referring to FIG. 7, the heating component 31 may be understood as a heating element in the atomizer 100 or a collection of a heating element and a thermally conductive element. The heating component 31 is disposed in the housing 1 and is configured to heat the atomizing liquid to generate an aerosol. A heating manner and a specific structure of the heating component 31 are not limited, as long as the heating component 31 can be configured to heat the atomizing liquid to generate the aerosol.

In some embodiments, referring to FIG. 7, the atomizer 100 may further include a liquid storage cavity 11. The liquid storage cavity 11 is located on a side of the heating component 31 close to the mouthpiece mounting position 14A, and is configured to supply atomizing liquid to the heating component 31.

In some embodiments, referring to FIG. 7, the housing 1 may include a body portion 112. A liquid storage cavity 11 is disposed in the body portion 112, and the heating component 31 is disposed on a side of the liquid storage cavity 11 away from the mouthpiece mounting position 14A, and is in communication with the liquid storage cavity 11. In this way, the atomizing liquid stored in the liquid storage cavity 11 can be continuously supplied to the heating component 31, especially when the atomizer 100 is in a state with the mouthpiece mounting position 14A facing downward, the heating component 31 is located below the liquid storage cavity 11, and the atomizing liquid in the liquid storage cavity 11 is actively delivered to the heating component 31 under the action of gravity, thereby being heated to generate the aerosol.

Referring to FIG. 7, the buffer cavity 124 is disposed in the housing 1, is disposed on a side of the heating component 31 away from the mouthpiece mounting position 14A, and is configured to buffer the aerosol generated by the heating component 31. It can be understood that the buffer cavity 124 may be configured to slowly store the atomizing liquid leaked from the liquid storage cavity 11 or the atomizing liquid condensed back.

In some embodiments, referring to FIG. 7, the housing 1 further includes a sealing seat 113. The sealing seat 113 is disposed on the other end of the body portion 112 along the first direction, that is, an end of the body portion 112 away from the mouthpiece mounting position 14A. The sealing seat 113 is spaced apart from the heating component 31, so as to form a buffer cavity 124 between the heating component 31 and the sealing seat 113.

An side of the heating component 31 away from the liquid storage cavity 11 may have an aerosol output port 311, and the aerosol output port 311 is in communication with the buffer cavity 124, so that the aerosol generated by the heating component 31 can enter the buffer cavity 124 for temporary storage.

In some embodiments, referring to FIG. 7, the sealing seat 113 may be a silicone member provided with a conductive member such as a conductive post or a conductive needle. The conductive member may be electrically connected to the heating component 31 through a conductive wiring to supply power to the heating component 31.

In some embodiments, referring to FIG. 7, the housing 1 is provided with an air inlet passage 123 and a discharge passage 125 in cooperation with the buffer cavity 124. The air inlet passage 123 and the discharge passage 125 are both in communication with the buffer cavity 124, and the buffer cavity 124 is located between the air inlet passage 123 and the discharge passage 125, so that the buffer cavity 124, the air inlet passage 123, and the discharge passage 125 jointly form the atomizing air passage 12 of the atomizer 100.

Referring to FIG. 6 and FIG. 7, the air inlet passage 123 is provided with an air inlet 1231 in communication with the exterior of the housing 1.

In some embodiments, the air inlet 1231 may be disposed on the body portion 112 and exposed outside the body portion 112. The air inlet 1231 is located between the buffer cavity 124 and the mouthpiece mounting position 14A in the first direction. When the atomizer 100 is in a use state with the mouthpiece mounting position 14A facing upward, the buffer cavity 124 is located below the air inlet 1231, and the atomizing liquid can only block the air inlet 1231 after it has completely filled the buffer cavity 124. This design effectively reduces the risk of blockage in the atomizing air passage 12, thereby enhancing the reliability of the air passage structure. The discharge passage 125 extends to the mouthpiece mounting position 14A to be in communication with the mouthpiece 14 located at the mouthpiece mounting position 14A (as shown in FIG. 8) for discharging the aerosol in the buffer cavity 124.

When the atomizer 100 is in use, external airflow is sucked into the air inlet passage 123 through the air inlet 1231, and then enters the buffer cavity 124 to take away the aerosol generated by the heating component 31 through the aerosol output port 311, and is discharged through the discharge passage 125.

In some embodiments, referring to FIG. 7, a liquid reservoir 1241 for storing the atomizing liquid is provided on the cavity wall of the buffer cavity 124 facing the mouthpiece mounting position 14A, so as to further increase the storage capacity of the buffer cavity 124 and reduce the possibility that the buffer cavity 124 is filled with the atomizing liquid. In this way, the anti-clogging performance of the atomizing air passage 12 is improved.

Exemplarily, the cavity wall of the buffer cavity 124 close to the air inlet passage 123 is provided with a liquid reservoir 1241, and the liquid reservoir 1241 may be located on the sealing seat 113, so that the atomizing liquid entering the buffer cavity 124 preferentially converges into the liquid reservoir 1241, and when the liquid reservoir 1241 is filled, and the atomizing liquid continues to converge in the buffer cavity 124.

In some embodiments, referring to FIG. 7, the buffer cavity 124 extends along the second direction, so that the axial direction of the buffer cavity 124 is substantially parallel to the second direction.

The air inlet passage 123 and the discharge passage 125 are located on two opposite sides of the buffer cavity 124 in the second direction. The air inlet passage 123 and the discharge passage 125 both extend in the direction parallel to the first direction. Exemplarily, the body portion 112 is provided with a respective hole structure 1123 on both sides of the heating component 31 in the second direction, so as to form an air inlet passage 123 and a discharge passage 125, respectively. In this way, the air inlet passage 123, the buffer cavity 124, and the discharge passage 125 jointly form the atomizing air passage 12 with a U-shaped structure.

It can be understood that “extend along the first direction” and “extend along the second direction” mentioned in the embodiments of the present disclosure both include being arranged along a direction parallel or substantially parallel to the first or second direction.

Compared with the atomizing air passage 12 with the bottom straight through layout, the arrangement of the atomizing air passage 12 with the U-shaped structure further helps to reduce the overall length of the air passage in the atomization device 1000. In this way, the path through which the aerosol passes from generation to discharge is short, which helps to maintain the temperature of the aerosol and reduce the attenuation of the flavor of the aerosol, thereby ensuring a consistent smoking experience. In addition, since there is no need to pass through many internal parts, it is helpful to reduce abnormal sound such as whistling sound generated by airflow, and further improve the use experience.

In some embodiments, referring to FIG. 7, the air inlet 1231 may be located on a side of the heating component 31 in the second direction, and is closer to the mouthpiece mounting position 14A than the heating component 31 in the first direction, that is, located laterally above the heating component 31 from the perspective shown in FIG. 7. This helps further reduce the risk of blockage of the air inlet 1231.

In some embodiments, referring to FIG. 7, the air inlet 1231 is disposed on a passage wall of the air inlet passage 123 away from the heating component 31. A flow guiding structure 1232 is disposed on a passage wall of the air inlet passage 123 facing the air inlet 1231 and is configured to guide the airflow entering from the air inlet 1231 to flow toward the heating component 31, so that the aerosol generated by the heating component 31 can be fully taken away by the air inlet airflow. This helps to enhance the fullness of the discharged aerosol, make the aerosol aroma rich, and improve the

Smoking Taste.

In some embodiments, the air inlet 1231 may be an air inlet hole disposed on a passage wall of the air inlet passage 123 away from the heating component 31. The flow guiding structure 1232 includes a flow guiding slope located on a passage wall of the air inlet passage 123 facing the air inlet 1231. The flow guiding slope gradually approaches the heating component 31 in the second direction from an end away from the buffer cavity 124 to an end close to the buffer cavity 124, so that the airflow is introduced into the buffer cavity 124 along a cavity wall of the buffer cavity 124 close to the heating component 31.

It can be understood that the specific arrangement and position of the flow guiding structure 1232 are not limited. For example, it may be other flow guiding structures such as a flow guiding curved surface and a flow guiding groove arranged on the passage wall of the air inlet passage 123 close to the heating component 31, as long as it can meet the flow guiding requirements.

When the atomization device 1000 is in use, a suction action causes airflow to flow, thereby triggering the activation of the airflow sensor 2 in the atomization device 1000. After the airflow sensor 2 is activated, the heating component 31 receives voltage to start heating, thus generating aerosol. If the airflow sensor 2 is in contact with the atomizing liquid, it is prone to contamination and fails.

In view of the above, in some embodiments, referring to FIG. 6 and FIG. 7, the atomizer 100 further includes an airflow sensor 2 and a detection air passage 13. The detection air passage 13 has a first end 134 in communication with the airflow sensor 2 and a second end 135 in communication with the discharge passage 125. The airflow sensor 2 is configured to detect a suction action and trigger the heating component 31 to work.

The distance between the first end 134 and the mouthpiece mounting position 14A in the first direction is not greater than the distance between the second end 135 and the mouthpiece mounting position 14A in the first direction, so that when the atomizer 100 is in the state with the mouthpiece mounting position 14A facing upward, the first end 134 is not lower than the second end 135, thereby limiting the contact of the atomizing liquid with the airflow sensor 2 before the detection air passage 13 is filled.

The airflow sensor 2 may be located on a side of the detection air passage 13 close to the mouthpiece mounting position 14A in the first direction. The detection air passage 13 is in communication with an end of the discharge passage 125 close to the mouthpiece mounting position 14A, so that the airflow sensor 2 is as far away from the buffer cavity 124 as possible, which can further reduce the risk of the airflow sensor 2 failing due to contact with the atomizing liquid.

Exemplarily, referring to FIG. 7, a side of the body portion 112 close to the mouthpiece mounting position 14A in the first direction has a protruding portion 1121. The housing 1 further includes a sealing member 114, and the sealing member 114 is located on an end of the body portion 112 away from the sealing seat 113 in the first direction. The mouthpiece mounting position 14A is disposed on the sealing member 114. The sealing member 114 has a mounting portion 1141 mounted on the protruding portion 1121, and the airflow sensor 2 is mounted in the mounting portion 1141. A gap substantially in the second direction is provided between the protruding portion 1121 and the mounting portion 1141 to form the detection air passage 13.

Referring to FIG. 7, in the detection air passage 13, a surface of the protruding portion 1121 facing the mounting portion 1141 may be convexly provided with a liquid baffle 1122, and the liquid baffle 1122 is located on a side of the detection air passage 13 close to the discharge passage 125. The surface of the mounting portion 1141 facing the protruding portion 1121 may be provided with a concave cavity 1142 corresponding to the liquid baffle 1122, so as to form a blocking structure that limits the atomizing liquid from flowing to the side of the detection air passage 13 close to the airflow sensor 2 and allows the airflow to pass through, which helps to further reduce the risk of failure of the airflow sensor 2.

It should be noted that when the position of the liquid baffle 1122 in the embodiments shown in FIG. 7 coincides with the position of the protruding structure 131 in the embodiments shown in FIG. 3, the two may be considered as the same component.

In some embodiments, referring to FIG. 8, the atomization device 1000 further includes a power supply assembly 200, and the power supply assembly 200 is configured to supply power to the atomizer 100.

In some examples, the power supply assembly 200 may be understood as a cell or a collection of a cell and related components such as a circuit board. In other embodiments, the battery and the circuit board may be of a non-integrated design, and may be located in different regions in the housing 1, such as the battery 5 and the circuit board 4 shown in FIG. 1.

In the embodiments shown in FIG. 8, the power supply assembly 200 and the atomizer 100 may be fixedly connected or detachably connected. When the power supply assembly 200 and the atomizer 100 are detachably connected, the atomizer 100 and the power supply assembly 200 may be replaced according to the use situation.

In some embodiments, referring to FIG. 8 and FIG. 9, the atomization device 1000 further includes a device shell 300, the atomizer 100 is disposed in the device shell 300, and the power supply assembly 200 may be disposed in the device shell 300. The device shell 300 is provided with a hollow structure 350 in communication with the exterior. The hollow structure 350 is in communication with the air inlet 1231 of the atomizer 100 in a staggered manner, so as to reduce whistling sound during inhalation through a circuitous airflow path. In addition, the device shell 300 between the hollow structure 350 and the air inlet 1231 can further limit the propagation of the generated airflow sound, while reducing the risk of external dust directly entering the atomizer 100.

For example, the device shell 300 includes a middle frame 310, a front cover 320 and a rear cover 330 that are disposed on two sides of the middle frame 310, respectively, and a mouthpiece 14340 mounted on an end of the middle frame 310 in the first direction. The hollow structure 350 may be an air guide hole disposed on the front cover 320. The air inlet 1231 is located on a side of the atomizer 100 in the second direction and is disposed toward the middle frame 310, so as to form a misalignment with the hollow structure 350. There is an air guide gap between the outer surface of the atomizer 100 and the inner surface of the device shell 300, so that the hollow structure 350 is in communication with the air inlet 1231, and the airflow can enter the device shell 300 from the hollow structure 350, flow through the air guide gap and then enter the atomizer 100 from the air inlet 1231. Compared with a manner in which the hollow structure 350 and the air inlet 1231 are disposed directly opposite to each other, the airflow sound during use of the device is reduced.

In the foregoing embodiments of the present disclosure, although the detection air passage 13 and the atomizing air passage 12 are separated as much as possible, to minimize an air passage shared by the detection air passage 13 and the atomizing air passage 12, in actual use, the aerosol in the electronic atomization device may move into the detection air passage 13, and form the condensate to flow to the airflow sensor as the temperature decreases. In some embodiments, in order to further solve the defect above, the length of the detection air passage may be extended, so that the airflow sensor is as far away from the shared air passage as possible, thereby increasing the difficulty of the residual aerosol moving to the airflow sensor and the difficulty of the condensate flowing to the airflow sensor. However, such an extension structure may increase the condensate due to the increase of the residual amount of the aerosol in the air passage, and affect the response speed of the airflow sensor.

In view of the above, referring to FIG. 10 to FIG. 13, in some embodiments, by providing an adsorption structure 30 between a suction hole 16 of the mouthpiece member 10 and a connection hole 21 of the sealing member 114, when the aerosol remaining between the connection hole 21 and the suction hole 16 moves toward the airflow sensor 2, the aerosol is adsorbed and intercepted by the adsorption structure 30 based on the capillary phenomenon. In addition, the condensate formed after cooling is adsorbed by the adsorption structure 30, so that the aerosol and/or the condensate is difficult to pass over the adsorption structure 30. The above improvements are described below through specific embodiments.

Specifically, in some embodiments, a detection air passage structure is provided to effectively intercept the movement of the aerosol to the airflow sensor. The detection air passage structure includes a mouthpiece member 10, a sealing member 114, and an adsorption structure 30. The mouthpiece member 10 defines a suction hole 16, and the generated aerosol is sucked through the suction hole 16. The sealing member 114 is connected to the mouthpiece member 10 so as to jointly define a detection air passage 13, and the detection air passage 13 is in communication with the suction hole 16. The sealing member 114 is provided with an airflow sensor 2, and the airflow sensor 2 is located in the detection air passage 13 and away from the suction hole 16. When suctioning, the airflow sensor 2 senses an airflow change and generates a feedback signal to the control module 400.

In some embodiments, referring to FIG. 10 to FIG. 15, the sealing member 114 further defines a connection hole 21, and the connection hole 21 provides communication between the atomizing air passage 12, the suction hole 16, and the detection air passage 13. When suctioning, the generated aerosol will flow from the atomizing air passage 12 through the connection hole 21 and the suction hole 16 in sequence to be sucked.

In some embodiments, the adsorption structure 30 is disposed on the sealing member 114 and/or the mouthpiece member 10. The adsorption structure 30 is located between the connection hole 21 and the suction hole 16, and is configured to adsorb the aerosol moving toward the detection air passage 13 and/or the condensate formed after the aerosol is cooled.

In some embodiments, the adsorption structure 30 is disposed on the sealing member 114. The adsorption structure 30 is located between the connection hole 21 and the suction hole 16, and is configured to adsorb the aerosol moving toward the detection air passage 13 and the condensate formed after the aerosol is cooled.

By disposing the adsorption structure 30, when the aerosol remaining between the connection hole 21 and the suction hole 16 moves toward the airflow sensor 2, the aerosol will be adsorbed and intercepted by the adsorption structure 30 based on the capillary phenomenon. In addition, after cooling, the condensate is formed and adsorbed by the adsorption structure 30, so that the aerosol and the condensate are difficult to move toward the airflow sensor 2 across the adsorption structure 30, thereby effectively protecting the airflow sensor 2.

Further, the suction hole 16 is spaced apart from the connection hole 21, so that the detection air passage 13 provides communication between the suction hole 16 and the connection hole 21.

Referring to FIG. 12 to FIG. 14, in some embodiments, the adsorption structure 30 may include a plurality of adsorption columns 301, and the plurality of adsorption columns 301 are spaced apart from each other and surround the peripheral side of the connection hole 21. A gap between adjacent adsorption columns 301 is small, so that it is difficult for the aerosol to directly pass through, thereby achieving interception and adsorption of the aerosol that tends to move toward the detection air passage 13.

Further, the adsorption column 301 may be a regular or irregular columnar structure such as a cylinder or a prism.

In specific embodiments, the surface of the adsorption column 301 may be provided with adsorption holes, adsorption bumps, etc., so as to increase the interception and adsorption effect on the aerosol by increasing the surface area of the adsorption column 301.

In some embodiments, the plurality of adsorption columns 301 may be integrally formed on the sealing member 114. The sealing member 114 is made of food-grade silicone material, so that the sealing member 114 and the adsorption structure 30 are integrally formed.

In other embodiments, the plurality of adsorption columns 301 may be integrally fixed on the sealing member 114, or independently fixed on the sealing member 114.

In other embodiments, the adsorption structure 30 may be a mesh structure or a porous structure, which can intercept and adsorb aerosols that tend to move towards the airflow sensor 2 while allowing the airflow in the detection air passage 13 to move during suction.

In some embodiments, referring to FIG. 12 to FIG. 15, the sealing member 114 includes a sealing body 1140 and a first protrusion 23. The first protrusion 23 protrudes from the sealing body 1140 toward the suction hole 16, and the first protrusion 23 and the sealing body 1140 are integrally formed.

The connection hole 21 passes through the sealing body 1140 and the first protrusion 23. The plurality of adsorption columns 301 are located on a peripheral side of the first protrusion 23, and the first protrusion 23 extends out relative to the plurality of adsorption columns 301 in the axial direction of the connection hole 21. Therefore, the distance between the connection hole 21 and the suction hole 16 can be shortened, so as to reduce the space for the aerosol to move to the detection air passage 13.

In some embodiments, the connection hole 21 and the suction hole 16 are coaxially arranged, so that the connection hole 21 and the suction hole 16 are directly opposite to each other. In this way, under the action of suction, the aerosol passing through the connection hole 21 will move towards the suction hole 16 more efficiently, thereby reducing the amount of the aerosol diffused between the connection hole 21 and the suction hole 16 towards the atomizing air passage 12. This reduces the amount of the aerosol adsorbed by the adsorption structure 30, thereby improving the protection of the airflow sensor 2.

In some embodiments, referring to FIG. 12, FIG. 13, and FIG. 15, the mouthpiece member 10 further has an accommodating cavity 17, and the accommodating cavity 17 provides communication between the connection hole 21, the suction hole 16, and the detection air passage 13. A liquid absorbing member 40 is provided in the accommodating cavity 17, and the liquid absorbing member 40 is configured to absorb the residual aerosol or condensate in the suction hole 16, thereby further reducing the amount of aerosol or condensate moving towards the detection air passage 13.

In some embodiments, referring to FIG. 14, the sealing member 114 defines a mounting hole 24, and the airflow sensor 2 is disposed in the mounting hole 24. The mounting hole 24 and the connection hole 21 are arranged side by side, and are staggered with the suction hole 16.

Referring to FIG. 12, FIG. 13, and FIG. 15, the mouthpiece member 10 may include a mouthpiece 14, a connection plate portion 15, a first baffle portion 151, a second baffle portion 152, and a third baffle portion 153. The mouthpiece 14 is connected to a side of the connection plate portion 15 away from the sealing member 114 and defines the suction hole 16.

The first baffle portion 151, the second baffle portion 152, and the third baffle portion 153 are respectively connected to a side of the connection plate portion 15 facing the sealing member 114, and the first baffle portion 151, the second baffle portion 152, and the third baffle portion 153 respectively abut against the sealing member 114.

In some embodiments, the first baffle portion 151 encloses an outer side of the adsorption structure 30 and forms a first cavity 161 jointly with the corresponding sealing member 114 and the connection plate portion 15, and the accommodating cavity 17 and the connection hole 21 are in communication in the first cavity 161.

The second baffle portion 152 encloses the outer side of the first baffle portion 151, and forms a second cavity 162 jointly with the corresponding sealing member 114 and the connection plate portion 15.

The third baffle portion 153 encloses the outer side of the second baffle portion 152 and forms a third cavity 163 jointly with the corresponding sealing member 114 and the connection plate portion 15, and the mounting hole 24 is in communication with the third cavity 163.

Referring to FIG. 14 and FIG. 15, the first baffle portion 151 is provided with a first notch 171, the second baffle portion 152 is provided with a second notch 172, and the first cavity 161, the second cavity 162, and the third cavity 163 are in communication. The detection air passage 13 includes the mounting hole 24, the third cavity 163, the second notch 172, the second cavity 162, the first notch 171, and the first cavity 161, all of which are in communication sequentially.

By providing the first notch 171 and the second notch 172, the communication between the first cavity 161 and second cavity 162 and between the second cavity 162 and the third cavity 163 is effectively restricted. This reduces the space for the aerosol to move from the first cavity 161 to the second cavity 162, and reduces the space for the aerosol to move from the second cavity 162 to the third cavity 163, thereby increasing the difficulty of the movement of the aerosol to the airflow sensor 2 and improving the interception amount of the aerosol.

Referring to FIG. 15, the first notch 171 and the second notch 172 may be staggered, so that the airflow path of the detection air passage 13 is more meandering and extended, thereby further increasing the difficulty of the movement of the aerosol to

The Airflow Sensor 2.

In some embodiments, referring to FIG. 12 to FIG. 15, the sealing member 114 may further include a second protrusion 25, the second protrusion 25 extends to the third cavity 163, and the mounting hole 24 passes through the second protrusion 25. In this way, a stroke of moving the airflow from the mounting hole 24 to the second cavity 162 through the third cavity 163 is prolonged.

The mouthpiece member 10 further includes a third protrusion 18, and the third protrusion 18 is disposed on the connection plate portion 15 and extends toward the second protrusion 25 to the third cavity 163. The third protrusion 18 is disposed directly opposite to the second protrusion 25.

In some embodiments, referring to FIG. 12, FIG. 14, and FIG. 15, the third protrusion 18 defines an avoidance hole 181, and the second protrusion 25 extends into the avoidance hole 181 and is close to the connection plate portion 15. In this way, the airflow enters the avoidance hole 181 through the mounting hole 24, then turns back from the avoidance hole 181 to the third cavity 163, and then enters the second cavity 162 from the third cavity 163 through the second notch 172, thereby prolonging a stroke of moving the airflow from the mounting hole 24 to the second cavity 162.

In some embodiments, the sealing member 114 defines a groove 26 on a peripheral side of the second protrusion 25, that is, the groove 26 is disposed around the peripheral side of the second protrusion 25 and faces the connection plate portion 15. The third protrusion 18 extends into the groove 26 and is close to the bottom of the groove 26, so that the end face of the third protrusion 18 close to the groove 26 is spaced apart from the bottom of the groove 26 by a certain distance.

Therefore, the airflow flows to the avoidance hole 181 through the mounting hole 24, turn back into the groove 26 from the avoidance hole 181, then turn back into the third cavity 163 from the bottom of the groove 26, then enter the second cavity 162 through the second notch 172, enter the first cavity 161 through the first notch 171, and finally flow out the suction port through the accommodating cavity 17.

Referring to FIG. 12, FIG. 13, and FIG. 15, in some other embodiments, the end face of the third protrusion 18 abuts against the sealing member 114, and the third protrusion 18 has a third notch 182 communicating the avoidance hole 181 with the third cavity 163. The third notch 182 is configured to allow airflow between the avoidance hole 181 and the third cavity 163 to circulate, thereby limiting a communication region between the third cavity 163 and the avoidance hole 181, and increasing difficulty of the movement of the aerosol to the airflow sensor 2.

The end face of the second protrusion 25 abuts against the mouthpiece member 10, and the second protrusion 25 has a fourth notch 251 communicating the mounting hole 24 with the avoidance hole 181. The fourth notch 251 is configured to allow the airflow between the mounting hole 24 and the avoidance hole 181 to circulate, thereby limiting the communication region between the mounting hole 24 and the avoidance hole 181, and increasing the difficulty of the movement of the aerosol to the airflow sensor 2.

In some embodiments, the third notch 182 and the fourth notch 251 are staggered. In this way, an airflow stroke of the detection air passage 13 is prolonged. In some specific implementations, the third notch 182 and the fourth notch 251 face away from each other.

In some embodiments, referring to FIG. 14 to FIG. 17, the cross section of the second protrusion 25 may be one of a semicircular structure, a C-shaped structure, and a door-hole-shaped structure. The cross section of the third protrusion 18 may be one of a semicircular structure, a C-shaped structure, and a door-hole-shaped structure.

Referring to FIG. 18 to FIG. 20 and in combination with FIG. 10 to FIG. 17, the atomization device 1000 includes the above detection air passage structure, and therefore, the atomization device 1000 has the beneficial effects of the detection air passage structure in any of the above embodiments, which will not be repeated here.

In some embodiments, the atomization device 1000 further includes a body, the body is connected to the mouthpiece member 10 and the sealing member 114, and the sealing member 114 is located between the mouthpiece member 10 and the body.

Specifically, the body may include a device shell 300, a bracket 500, an airflow sensor 2, an atomizing core 3, a power supply assembly 200, a control module 400, and the like.

In some embodiments, the device shell 300 and the mouthpiece member 10 are fixedly connected to define a mounting cavity 800. The bracket 500 and the sealing member 114 are disposed in the mounting cavity 800, and the sealing member 114 is located between the bracket 500 and the mouthpiece member 10. The airflow sensor 2 is disposed in the mounting hole 24 of the sealing member 114. The atomizing core 3 is disposed between the connection hole 21 of the sealing member 114 and the bracket 500. The atomizing core 3, the sealing member 114, and the bracket 500 jointly define a liquid storage cavity 11. The liquid storage cavity 11 is configured to accommodate an aerosol substrate.

In some embodiments, the liquid storage cavity 11 is further provided with a liquid storage cotton. The power supply assembly 200 and the control module 400 are disposed in the mounting cavity 800. The control module 400 may be electrically connected to the power supply assembly 200, the airflow sensor 2, and the atomizing core 3, respectively.

In some embodiments, the atomizing core 3 includes a mounting tube 32, a liquid guiding cotton 33, and a heating component 31. Outer walls of two opposite ends of the mounting tube 32 are respectively connected to the bracket 500 and the connection hole 21 of the sealing member 114 in a sealed manner, and the mounting tube 32 is constructed with the atomizing air passage 12.

In some embodiments, the mounting tube 32 is provided with a liquid guiding hole 321, and the liquid guiding hole 321 is in communication with both the liquid storage cavity 11 and the atomizing air passage 12. The liquid guiding cotton 33 is disposed in the atomizing air passage 12 and located at the liquid guiding hole 321. The heating component 31 is electrically connected to the control module 400 and is located on the inner wall of the liquid guiding cotton 33. The heating component 31 is configured to heat the aerosol substrate that moves to the liquid guiding cotton 33 through the liquid guiding hole, so that the heated aerosol substrate is atomized to form an aerosol, and moves along the atomizing air passage 12 toward the suction hole 16.

Referring to FIG. 21 to FIG. 32, in some embodiments, as shown in FIG. 21 to FIG. 32, in order to prevent the accumulated condensate from flowing through the detection air passage 13 to the airflow sensor 2, which would affect the service life of the atomization device 1000, the structure of the detection air passage 13 may be improved, which will be described in detail below.

In some embodiments, the mouthpiece member 10 is constructed with a first sub-detection air passage 1301. The atomization device 1000 further includes an accommodating member 6, constructed with a second sub-detection air passage 1302 and a receiving cavity 62 in communication with each other. The accommodating member 6 and the mouthpiece member 10 are connected in a sealed manner to form a detection air passage 13. The detection air passage 13 includes the first sub-detection air passage 1301, the second sub-detection air passage 1302, and the receiving cavity 62, all of which are in communication sequentially. The receiving cavity 62 includes a first receiving cavity 621 and a second receiving cavity 622, and the first receiving cavity 621 provides communication between the second sub-detection air passage 1302 and the second receiving cavity 622. The airflow sensor 2 is disposed in the second receiving cavity 622 in a sealed manner, and the detection surface 51 of the airflow sensor 2 faces the first receiving cavity 621. The accommodating member 6 includes a first flow guiding part 63 and a second flow guiding part 64. The first flow guiding part 63 and the second flow guiding part 64 are disposed in the first receiving cavity 621 and both extend toward the second receiving cavity 622. The first flow guiding part 63 has a first opening, and the first opening faces away from the second sub-detection air passage 1302. The second flow guiding part 64 has a second opening 341, and the second opening 341 faces the second sub-detection air passage 1302 and is located in the first opening. The detection surface 51 faces the flow guiding space 626 of the second flow guiding part 64.

The first flow guiding part 63 and the second flow guiding part 64 is disposed in the first receiving cavity 621 of the detection air passage 13, the first opening of the first flow guiding part 63 is disposed away from the second sub-detection air passage 1302, and the second opening 341 of the second flow guiding part 64 is located in the first opening and faces the second sub-detection air passage 1302, so that a reverse airflow path is formed between the first flow guiding part 63, the second flow guiding part 64, and the first receiving cavity 621. The airflow sensor 2 is disposed in the second receiving cavity 622 of the detection air passage 13 in a sealed manner, and the detection surface 51 of the airflow sensor 2 faces the flow guiding space 626 of the second flow guiding part 64, so that during suction, the airflow that triggers the airflow sensor 2 to generate a feedback detection signal will change its direction upon passing through the second opening 341 from the flow guiding space 626, and passes through the space between the first flow guiding part 63 and the second flow guiding part 64, then change its direction again and passes through the space between the first flow guiding part 63 and the inner wall of the first receiving cavity 621 to enter the second sub-detection air passage 1302, and finally flow out through the first sub-detection air passage 1301. The condensate formed after the aerosol diffused into the first sub-detection air passage 1301 and the second sub-detection air passage 1302 condenses will converge in the space between the second flow guiding part 64 and the first receiving cavity 621 under the blocking and guidance of the first baffle portion. This prevents the condensate from entering the flow guiding space 626 and affecting the normal operation of the airflow sensor 2, as well as preventing the condensate from blocking the detection air passage 13.

Referring to FIG. 21, in some embodiments, the mouthpiece member 10 may be embedded in the housing 1 and at least partially extend out of the housing 1.

Referring to FIG. 22 to FIG. 25, the atomization device 1000 specifically includes an accommodating member 6, a sealing member 114, an airflow sensor 2, an atomizing core 3, a sealing seat 113, a liquid absorbing member 40, a sealing sleeve 9, a sealing rubber sleeve 115, and a control module 400 that are disposed in the housing 1.

In some embodiments, the sealing member 114 is connected between the mouthpiece member 10 and the accommodating member 6 in a sealed manner. The sealing member 114, the mouthpiece member 10, and the accommodating member 6 jointly define a detection air passage 13, and the airflow sensor 2 is sealed in the accommodating member 6 through the sealing sleeve 9 and is located in the detection air passage 13.

In some embodiments, the sealing seat 113 is sealed on an end of the accommodating member 6 away from the sealing member 114. The sealing seat 113, the accommodating member 6, the sealing member 114, and the mouthpiece member 10 jointly define an atomizing air passage 12. The sealing seat 113, the accommodating member 6 and the sealing member 114 jointly define a liquid storage cavity 11, and the liquid storage cavity 11 is configured to receive a liquid aerosol substrate.

In some embodiments, the atomizing core 3 is sealed on the accommodating member 6 by the sealing rubber sleeve 115. The atomizing core 3 is configured to heat the liquid aerosol substrate when energized, so that the heated aerosol substrate is atomized to form an aerosol, and the aerosol is released to the atomization channel.

In some embodiments, the liquid absorbing member 40 is disposed between the mouthpiece member 10 and the sealing member 114, and is configured to absorb and latch the condensate in the mouthpiece member 10, where the condensate is formed after the aerosol remaining in the atomization device 1000 is cooled.

In some embodiments, the control module 400 is disposed in a mounting space 95 enclosed by the sealing seat 113 and the housing 1. The control module 400 is electrically connected to the atomizing core 3 and the airflow sensor 2 respectively, and is configure to receive a feedback signal from the airflow sensor 2 in a power-on state to control the atomizing core 3 to generate heat. In some embodiments, the control module 400 may be a control circuit board.

In some embodiments, the mouthpiece member 10 defines a first sub-detection air passage 1301. The accommodating member 6 defines a second sub-detection air passage 1302 and a receiving cavity 62 in communication with each other. The accommodating member 6 and the mouthpiece member 10 are connected in a sealed manner to define the detection air passage 13. The detection air passage 13 includes the first sub-detection air passage 1301, the second sub-detection air passage 1302, and the receiving cavity 62, all of which are in communication sequentially.

Referring to FIG. 24, the receiving cavity 62 includes a first receiving cavity 621 and a second receiving cavity 622. The first receiving cavity 621 provides communication between the second sub-detection air passage 1302 and the second receiving cavity 622. The airflow sensor 2 is sealed in the second receiving cavity 622, and the detection surface 51 of the airflow sensor 2 faces the first receiving cavity 621.

Referring to FIG. 25, the accommodating member 6 includes a first flow guiding part 63 and a second flow guiding part 64. The first flow guiding part 63 and the second flow guiding part 64 are disposed in the first receiving cavity 621 and both extend toward the second receiving cavity 622. The first flow guiding part 63 has a first opening, and the first opening faces away from the second sub-detection air passage 1302. The second flow guiding part 64 has a second opening 341, and the second opening 341 faces the second sub-detection air passage 1302. A part of the second flow guiding part 64 close to the second opening 341 is located in the first opening, and the second flow guiding part 64 defines a flow guiding space 626. The detection surface 51 faces the flow guiding space 626 of the second flow guiding part 64, so that the airflow sensor 2 can only generate the feedback signal when the airflow in the flow guiding space 626 flows.

In some embodiments, since the first opening and the second opening 341 face oppositely, and the second opening 341 is located in the first opening, during suction, the airflow that triggers the airflow sensor 2 to generate a feedback detection signal will change its direction upon passing through the second opening 341 from the flow guiding space 626, and passes through the space between the first flow guiding part 63 and the second flow guiding part 64, then change its direction again and passes through the space between the first flow guiding part 63 and the inner wall of the first receiving cavity 621 to enter the second sub-detection air passage 1302, and finally flow out through the first sub-detection air passage 1301. The condensate formed after the aerosol diffused into the first sub-detection air passage 1301 and the second sub-detection air passage 1302 condenses will converge in the space between the second flow guiding part 64 and the first receiving cavity 621 under the blocking and guidance of the first baffle portion. This prevents the condensate from entering the flow guiding space 626 and affecting the normal operation of the airflow sensor 2, as well as preventing the condensate from blocking the detection air passage 13.

In some embodiments, still referring to FIG. 25, a first space 623 is formed between the first outer sidewall 332 of the first flow guiding part 63 and the inner wall of the first receiving cavity 621. A second space 624 is formed between the first inner sidewall 333 of the first flow guiding part 63 and the second outer sidewall 342 of the corresponding second flow guiding part 64. The second inner sidewall 343 of the second flow guiding part 64 defines the flow guiding space 626. A liquid collection space 625 is formed between the second outer sidewall 342 of the second flow guiding part 64 and the inner wall of the corresponding first receiving cavity 621. The liquid collection space 625 and the second space 624 are in communication with the first space 623.

During suction, the detection airflow sensed by the detection surface 51 flows out through the flow guiding space 626, the second space 624, the first space 623, the second sub-detection air passage 1302, and the first sub-detection air passage 1301 in sequence.

During liquid collection, the condensate flows to the liquid collection space 625 through the first sub-detection air passage 1301, the second sub-detection air passage 1302, and the first space 623 in sequence.

In some embodiments, a liquid storage member may be further disposed in the liquid collection space 625, and the liquid storage member is configured to suck and latch the condensate. The liquid storage member may be a material that can absorb condensate, such as sponge or cotton.

In some specific embodiments, referring to FIG. 26 to FIG. 29, the first flow guiding part 63 is one of a semicircular structure, a V-shaped structure, a C-shaped structure, and a doorhole-shaped structure of the first opening facing away from the second sub-detection air passage 1302. The second flow guiding part 64 is one of a semicircular structure, a V-shaped structure, a C-shaped structure, and a doorhole-shaped structure of the second opening 341 facing the second sub-detection air passage 1302.

In some specific embodiments, referring to FIG. 30 to FIG. 31, the first flow guiding part 63 may be a structure whose opening ends are relatively close to each other on the basis of the above-mentioned semicircular structure, the V-shaped structure, the C-shaped structure, or the doorhole-shaped structure. The second flow guiding part 64 may be a structure whose second opening ends are relatively close to each other on the basis of the above-mentioned semicircular structure, the V-shaped structure, the C-Shaped structure, or the doorhole-shaped structure.

In some embodiments, referring to FIG. 22 to FIG. 25, the airflow sensor 2 may be sealed in the second receiving cavity 622 by the sealing sleeve 9. The sealing sleeve 9 includes an integrally formed end portion 91 and a ring portion 92. The end portion 91 and the ring portion 92 are connected in a sealed manner to define a sealing groove 93. The ring portion 92 is connected, in a sealed manner, between the peripheral side of the airflow sensor 2 and the inner wall of the second receiving cavity 622. The end portion 91 abuts between the detection surface 51 and at least the second end face 344 of the second flow guiding part 64 facing the second receiving cavity 622, so that the detection surface 51 is only in direct communication with the flow guiding space 626, and is not in direct communication with the second space 624 and the liquid collection space 625.

In some embodiments, the end portion 91 abuts between the detection surface 51 and the first end face 334 of the first flow guiding part 63 facing the second receiving cavity 622, and between the detection surface 51 and the second end face 344.

In some embodiments, referring to FIG. 22, the end portion 91 is provided with at least one through hole 94, the through hole 94 provides communication between the flow guiding space 626 and the detection surface 51, and the through hole 94 is configured to be in communication with both the detection surface 51 and the flow guiding space 626.

In some embodiments, referring to FIG. 22 to FIG. 24 and FIG. 32, the sealing member 114 defines a third sub-detection air passage 1303 providing communication between the first sub-detection air passage 1301 and the second sub-detection air passage 1302. The detection air passage 13 includes the first sub-detection air passage 1301, the third sub-detection air passage 1303, the second sub-detection air passage 1302, and the receiving cavity 62, all of which are in communication sequentially.

In some embodiments, the sealing member 114 may include an integrally formed sealing body 1140 and a first baffle structure 1143. The first baffle structure 1143 extends into the first sub-detection air passage 1301, and the first baffle structure 1143 and the sealing body 1140 jointly define the third sub-detection air passage 1303. A liquid sump 11401 is defined by the third outer sidewall 432 of the first baffle structure 1143, the inner wall of the corresponding first sub-detection air passage 1301, and the sealing body 1140.

During liquid collection, the condensate formed in the first sub-detection air passage 1301 converges in the liquid sump 11401. In this way, the condensate in the first sub-detection air passage 1301 can be effectively collected, and the condensate in the first sub-detection air passage 1301 can be effectively prevented from entering the liquid collection space 625 through the third sub-detection air passage 1303 and the second sub-detection air passage 1302. This further reduces the influence of the condensate generated in the first sub-detection air passage 1301 on the airflow sensor 2.

In some embodiments, the liquid absorbing member 40 is disposed in the liquid sump 11401, and is configured to absorb and latch the condensate generated in the first sub-detection air passage 1301. This arrangement prevents the condensate in the liquid sump 11401 from flowing into the liquid collection space 625 when the atomization device 1000 is positioned laterally, and further reduces the influence of the condensate formed in the first sub-detection air passage 1301 on the airflow sensor 2.

In some specific implementations, the liquid absorbing member 40 may be a material that can absorb condensate, such as sponge or cotton.

In some embodiments, referring to FIG. 32, the first baffle structure 1143 has a third end face 431 and a third outer sidewall 432. The third end face 431 faces away from the sealing body 1140, and the third outer sidewall 432 is connected between the third end face 431 and the sealing body 1140. The third outer sidewall 432 is at least partially inclined toward the inner wall of the corresponding first sub-detection air passage 1301 from the connection position with the third end face 431 toward the sealing body 1140, so that the condensate generated in the third outer sidewall 432 flows into the liquid sump 11401.

In some embodiments, referring to FIG. 22 to FIG. 24, the atomizing air passage 12 includes a first sub-atomizing air passage 1201, a second sub-atomizing air passage 1202, and a third sub-atomizing air passage 1203, all of which are in communication sequentially. The mouthpiece member 10 defines the first sub-atomizing air passage 1201, the accommodating member 6 defines the second sub-atomizing air passage 1202, and the sealing member 114 defines the third sub-atomizing air passage 1203.

An end of the first sub-atomizing air passage 1201 away from the second sub-atomizing air passage 1202 is in communication with an end of the first sub-detection air passage 1301 away from the second sub-detection air passage 1302. The first sub-detection air passage 1301 and an end of the first sub-atomizing air passage 1201 close to the sealing member 114 are separated by the liquid absorbing member 40. In this way, the aerosol in the detection air passage 13 can only be in communication at the end of the mouthpiece member 10 away from the sealing member 114. This effectively controls the amount of the aerosol diffused into the detection air passage 13 and reduces the amount of the condensate formed in the detection air passage.

In some embodiments, referring to FIG. 22 to FIG. 24 and FIG. 32, the sealing member 114 further includes a second baffle structure 1144 and a second baffle structure 1144, all of which are integrally formed with the sealing body 1140. The second baffle structure 1144 extends into the first sub-atomizing air passage 1201, and the second baffle structure 1144 and the sealing body 1140 jointly define the third sub-atomizing air passage 1203. The second baffle structure 1144 protrudes from the liquid sump 11401 and extends toward the first sub-atomizing air passage 1201.

During liquid collection, the condensate formed in the first sub-atomizing air passage 1201 converges in the liquid sump 11401 and is sucked and latched by the liquid absorbing member 40, thereby effectively preventing the condensate in the first sub-atomizing air passage 1201 from flowing to the atomizing core 3 and blocking the atomizing air passage 12.

In some embodiments, the sealing body 1140 defines a liquid collection hole 45. The open end of the liquid collection hole 45 is in communication with the bottom of the liquid sump 11401, such that the condensate converging in the liquid sump 11401 will accumulate preferentially in the liquid collection hole 45. The liquid absorbing member 40 covers the open end of the liquid collection hole 45, or the liquid absorbing member 40 extends into the liquid collection hole 45.

In some embodiments, referring to FIG. 22 to FIG. 24, an atomization cavity 601 is defined by the sealing seat 113 and the accommodating member 6. The atomizing core 3 is disposed in the atomization cavity 601. The atomizing air passage 12 includes the first sub-atomizing air passage 1201, the third sub-atomizing air passage 1203, the second sub-atomizing air passage 1202, and the atomization cavity 601, all of which are in communication sequentially. The aerosol formed by heating and atomizing by the atomizing core 3 flows out through the atomization cavity 601, the second sub-atomizing air passage 1202, the third sub-atomizing air passage 1203, and the first sub-atomizing air passage 1201 in sequence.

In some embodiments, the movement direction of the aerosol in the atomization cavity 601 is different from the movement direction of the aerosol in the second sub-atomizing air passage 1202, so that the movement direction of the aerosol from the atomization cavity 601 to the second sub-atomizing air passage 1202 needs to be changed.

In some embodiments, the movement direction of the aerosol in the atomization cavity 601 may be perpendicular to the movement direction of the aerosol in the second sub-atomizing air passage 1202.

Therefore, referring to FIG. 22 to FIG. 24, in some embodiments, the sealing seat 113 includes a first guide surface 71 corresponding to a position of the atomization cavity 601 close to the second sub-atomizing air passage 1202. The first guide surface 71 is configured to guide the aerosol in the atomization cavity 601 so as to turn the flow into the second sub-atomizing air passage 1202. The first guide surface 71 may be, but is not limited to, a guide surface structure that can guide the aerosol in the atomization cavity 601 to smoothly change the flow direction into the second sub-atomizing air passage 1202.

In some embodiments, the accommodating member 6 is provided with a second guide surface 36 corresponding to at least a position of the second sub-atomizing air passage 1202 close to the atomization cavity 601, and the second guide surface 36 is configured to guide the aerosol in the atomization cavity 601 to turn the flow into the second sub-atomizing air passage 1202. The second guide surface 36 may be, but is not limited to, a guide surface structure that can guide the aerosol in the atomization cavity 601 to smoothly change the flow direction into the second sub-atomizing air passage 1202.

In some embodiments, the sealing seat 113 is provided with a first guide surface 71 corresponding to a position of the atomization cavity 601 close to the second sub-atomizing air passage 1202, and the accommodating member 6 is provided with a second guide surface 36 corresponding to at least a position of the second sub-atomizing air passage 1202 close to the atomization cavity 601, and the first guide surface 71 is in contact connection with the second guide surface 36, so that the aerosol in the atomization cavity 601 can smoothly flow into the second sub-atomizing air passage 1202.

In some embodiments, referring to FIG. 22 to FIG. 24, the cross section of the second sub-atomizing air passage 1202 along the flow direction of the aerosol gradually decreases, so that the flow velocity of the aerosol entering the third sub-atomizing air passage 1203 and the first sub-atomizing air passage 1201 through the second sub-atomizing air passage 1202 can be effectively increased, thereby improving the user experience.

In some embodiments, the cross section of the third sub-atomizing air passage 1203 along the flow direction of the aerosol gradually decreases, so that the flow velocity of the aerosol entering the first sub-atomizing air passage 1201 through the third sub-atomizing air passage 1203 can be effectively increased, thereby improving the user experience.

In some embodiments, the area of the cross section of the second sub-atomizing air passage 1202 along the flow direction of the aerosol gradually decreases. The area of the cross section of the third sub-atomizing air passage 1203 along the flow direction of the aerosol gradually decreases.

In other embodiments, the area of the cross section of the first sub-atomizing air passage 1201 along the flow direction of the aerosol may also gradually decrease.

In some embodiments, referring to FIG. 22 to FIG. 24, the atomizing core 3 is a ceramic heating element, and the ceramic heating element is connected to the liquid outlet of the liquid storage cavity 11 through the sealing rubber sleeve 115 in a sealed manner.

In some embodiments, the ceramic heating element includes a heating surface 34 and a liquid guiding groove 35. The opening of the liquid guiding groove 35 faces the liquid storage cavity 11 and is in communication with the liquid storage cavity 11, so as to increase a contact area between the ceramic heating element and the aerosol substrate, thereby increasing a liquid guiding amount. The heating surface 34 faces the atomization cavity 601, and is configured to heat and atomize an aerosol substrate to form an aerosol, and release the aerosol into the atomization cavity 601.

In some embodiments, referring to FIG. 22 to FIG. 24, the housing 1 is further provided with an air inlet 1231, the air inlet 1231 is in communication with both the mounting space 95 and the exterior of the housing 1. The accommodating member 6 is provided with a vent hole 37, and the vent hole 37 is in communication with both the mounting space 95 and the atomization cavity 601. During inhalation, the external airflow sequentially flows through the air inlet 1231, the mounting space 95, and the vent hole 37 to enter the atomization cavity 601, and the airflow is mixed with the generated aerosol in the atomization cavity 601. The mixture then flows out after sequentially passing through the second sub-atomizing air passage 1202, the third sub-atomizing air passage 1203, and the first sub-atomizing air passage (1201).

In some embodiments, the external airflow flowing through the mounting space 95 can effectively dissipate heat of the control module 400 mounted in the mounting space 95.

In some embodiments, the airflow sensor 2 may send a feedback signal to the control module 400 by sensing based on negative pressure.

In some other embodiments, the mounting space 95 may further be in communication with the second receiving cavity 622, so that when the external airflow passes through the airflow sensor 2 after sequentially passing through the air inlet 1231 and the mounting space 95, the airflow sensor 2 is triggered to send a feedback signal to the control module 400.
