FIELD

The present disclosure relates to the field of electronic atomization technology, and in particular to an aerosol generating device.

BACKGROUND

Currently in the electronic atomization industry, tobacco paste-type aerosol generating devices are mainly suitable for solid or semi-solid atomizing medium. Compared with real cigarettes that burn tobacco, the advantage is that it uses evaporation or baking to replace the combustion process, thus avoiding the production of many irritating, toxic and carcinogenic substances. The tobacco paste-type aerosol generating device currently available on the market generally includes a housing, an atomizing assembly, and a power supply assembly. The power supply assembly is provided in the housing, and the two are assembled to form an inhalation device. An atomization assembly is mounted on the inhalation device. During use, the power supply assembly supplies power to the atomizing assembly, and a heating element of the atomizing assembly is energized and an atomizing medium stored in the atomizing assembly is heated and melted, and the atomizing medium generates an aerosol for the user to inhale.

However, the conventional aerosol generating devices have no temperature control function, and the heat generated by the heating element each time is close to constant. As the remaining amount of atomizing medium changes or the ambient temperature changes, the temperature of the atomizing medium cannot be within a temperature range most suitable for melting. This will cause the atomizing medium to fail to melt due to the heating temperature being too low, or cause the atomizing medium to boil and leak out of the housing due to the heating temperature being too high, causing the aerosol generating device to be unable to be used normally.

SUMMARY

Accordingly, it is necessary to provide an aerosol generating device that can solve the problem that conventional aerosol generating devices have no temperature control function, resulting in an atomizing medium being unable to melt due to a heating temperature being too low, or boiling and causing liquid leakage due to a heating temperature being too high.

An aerosol generating device includes a housing, an atomizing assembly, a temperature sensing element, and a power supply assembly. The atomizing assembly is provided in the housing, the atomizing assembly includes an oil cup and a heating element provided on the oil cup, and the heating element is configured to heat the oil cup to heat an atomizing medium in the oil cup.

In one embodiment, the atomizing assembly further includes a thermal insulator, the thermal insulator is attached to the side of the heating element away from the oil cup and covers the heating element, and the temperature sensing element is located between the thermal insulator and the heating element.

In one embodiment, the thermal insulator is adhered to an outer side of the heating element; or a side of the thermal insulator away from the heating element is covered with a second adhesive layer configured to fix the thermal insulator to the heating element.

In one embodiment, the temperature sensing element is a thermistor, and a resistance of the thermistor changes in response to a change of the temperature change parameter of the oil cup.

In one embodiment, the power supply assembly includes a battery and a control board electrically connected to the battery, and the control board is electrically connected to the heating element and is communicatively connected to the temperature sensing element.

In one embodiment, the housing is provided with an atomizing cavity in communication with an external environment, an atomizing core electrically connected to the power supply assembly is provided at an end of the oil cup, the atomizing core has an oil inlet surface and an atomizing surface, the oil inlet surface faces an inner cavity of the oil cup, the atomizing surface faces the atomizing cavity, and the atomizing core is configured to heat and atomize the atomizing medium heated and melted by the heating element to generate an aerosol.

In the aerosol generating device, the temperature sensing element communicatively connected to the power supply assembly is provided on the heating element, and when the heating element heats the oil cup, the temperature sensing element can acquire the temperature change parameter of the oil cup in real time, and the power supply assembly can control the power supplied to the heating element according to the temperature change parameter of the oil cup. For example, when the temperature of the atomizing medium in the oil cup is low, the power supply assembly can control the heating element to heat the oil cup with a higher power. When the temperature of the oil cup approaches or reaches a preset temperature, the heating power is controlled to make the temperature of the atomizing medium within a temperature range suitable for melting, which can effectively prevent the atomizing medium from failing to melt due to too low a temperature, or from boiling and causing liquid leakage due to too high a temperature, thereby preventing the aerosol generating device from being unable to be used normally.

An aerosol generating device 10 is provided according to an embodiment of the present disclosure. The aerosol generating device is configured to heat an atomizing medium (such as tobacco paste or tobacco liquid) contained therein to form an aerosol for a user to inhale.

Hereinafter, the configuration of the aerosol generating device 10 in the present disclosure will be described by taking an electronic cigarette configured to heat solid or semi-solid tobacco paste or liquid tobacco liquid to generate aerosol as an example. This embodiment is merely used as an example for illustration and does not limit the scope of the present disclosure. It can be understood that in other embodiments, the aerosol generating device of the present disclosure is not limited to the above-mentioned aerosol generating device for heating tobacco paste or tobacco liquid, but can also be other aerosol generating devices for heating a solid, semi-solid or liquid atomizing medium to generate aerosol, which is not limited herein.

Referring to FIGS. 1 to 4, FIG. 1 is a perspective view of an aerosol generating device 10 according to an embodiment of the present disclosure, FIG. 2 is a perspective view showing an internal structure of the aerosol generating device 10 according to the embodiment, and FIGS. 3 and 4 are cross-sectional views of an aerosol generating device 10 according to the embodiment. The aerosol generating device 10 includes a housing 100, an atomizing assembly 200, and a power supply assembly 300. The atomizing assembly 200 and the power supply assembly 300 are both provided in the housing 100. The power supply assembly 300 is configured to supply power to the atomizing assembly 200. When the power supply assembly 300 supplies power to the atomizing assembly 200, the atomizing assembly 200 can heat an atomizing medium 50 contained in the atomizing assembly 200 to generate an aerosol.

Specifically, as shown in FIGS. 2, 3 and 4, in the embodiment, the housing 100 includes an outer shell 110 and a sealing member 120 provided in the outer shell 110. The outer shell 110 has an inner cavity and is provided with an air outlet 101 in communication with the inner cavity and a charging hole 102. The sealing member 120 is, in one embodiment, made of silicone material, which is connected to the air outlet 101 through a ventilation pipe 400. The ventilation pipe 400 is provided with a main air channel 401 extending through opposite ends thereof. An outer wall of the sealing member 120 is provided with an air inlet 120a, and the sealing member 120 is provided with an atomizing cavity 121 and a mounting position 122 in communication with each other. The atomizing cavity 121 is in communication with the air inlet 120a and is in communication with the air outlet 101 through the main air channel 401. The atomization assembly 200 is provided in the mounting position 122. The power supply assembly 300 is provided in the outer shell 110. After being energized, the atomizing assembly 200 can generate aerosol in the atomizing cavity 121. In an embodiment, the mounting position 122 and the main air channel 401 are perpendicular to each other and are in communication with each other through the atomizing cavity 121. When the user inhales, an airflow can enter the atomizing cavity 121 from the charging hole 102 through the air inlet 120a, mixed with the aerosol, and then be inhaled by the user from the air outlet 101 through the main air passage 401.

Since the atomizing cavity 121 is provided in the sealing member 120, after the atomizing medium is heated and atomized, the aerosol can be concentrated in the atomizing cavity 121 without flowing around, thereby effectively reducing the loss of the aerosol and preventing the aerosol from flowing to other structures in the housing 100, and ensuring that as much aerosol as possible is gathered in the atomizing cavity 121, and then discharged from the air outlet 101 to be inhaled by the user, thus avoiding the waste of the atomizing medium.

Referring to FIGS. 3 and 4, in one embodiment, the atomizing assembly 200 includes an oil cup 210 and an atomizing core 220. The oil cup 210 is of a hollow cylindrical structure and is made of a material with good thermal conductivity, such as metal or ceramic. The oil cup 210 is coaxially provided in the mounting position 122 and is provided with an accommodating cavity 210a extending through opposite ends thereof in an axial direction. Since a central axis of the mounting position 122 is perpendicular to a central axis of the main air channel 401, a central axis of the accommodating cavity 210a is also perpendicular to the central axis of the main air channel 401. Specifically, as shown in FIG. 5, the accommodating cavity 210a includes a first cavity 210b and a second cavity 210c that are in communication with each other and are coaxially provided. An inner diameter of the first cavity 210b is greater than an inner diameter of the second cavity 210c. The first cavity 210b is configured to accommodate the atomizing medium. The atomizing core is provided in the second cavity 210c, and the atomizing core 220 has an oil inlet surface 221 and an atomizing surface 222 that are oppositely provided. The oil inlet surface 221 faces the first cavity 210b. More specifically, the atomizing core 220 includes an oil guide member and a heating member. The oil guide member is made of ceramic or oil guide cotton, and a side thereof facing the first cavity 210b forms an oil guide surface. The heating member is provided on a side of the oil guide member away from the oil inlet surface 221 and forms the atomizing surface 222. The atomizing surface 222 faces the atomizing cavity 121. The oil guide member is configured to guide the atomizing medium 50 in the first cavity 210b to the heating member. The heating member is configured to heat and atomize the guided atomizing medium 50 to generate aerosol.

Further, in some cases, when the atomizing medium 50 is a solid or semi-solid tobacco paste, in order to enable the atomizing medium 50 to melt and flow to the atomizing core 220, as shown in FIGS. 3, 4 and 6, the atomizing assembly 200 further includes a heating element 230 provided on the oil cup 210. The heating element 230 is configured to heat the oil cup 210 to preheat the atomizing medium 50 in the oil cup 210 through heat transfer, and the atomizing medium 50 can be melted and flow. In an embodiment, the heating element 230 is provided on a side wall of the oil cup 210. For example, the heating element 230 may be attached to an outer side of the side wall of the oil cup 210, or may be embedded in a side wall of the oil cup 210, or provided on an inner side of the side wall of the oil cup 210. Specifically, the heating element 230 is an annular FPC (Flexible Printed Circuit) attached to an outer peripheral surface of the oil cup 210. The FPC has excellent flexibility and advantages of light weight, thin thickness, and good bendability. Therefore, the heating element 230 can be tightly attached to the outer peripheral surface of the oil cup 210, and the heat of the heating element 230 can be quickly transferred to the oil cup 210, and the oil cup 210 can be heated evenly to ensure that the atomizing medium 50 is heated evenly.

It should be understood that the heating element 230 may be a metal sheet, a semiconductor sheet, etc., which is not limited hereto.

Further, in order to firmly fix the heating element 230 to the oil cup 210 and prevent the heating element 230 from falling off from the oil cup 210, the heating element 230 can be adhered to the outer side of the oil cup 210 by glue. In one embodiment, as shown in FIG. 7, the side of the heating element 230 away from the oil cup 210 is covered with a first adhesive layer 240 such as an adhesive tape, a double-sided tape, a solid glue, etc., and the heating element 230 can be firmly fixed to the oil cup 210 through the first adhesive layer 240.

In other embodiments, the atomizing assembly 200 may be provided with only the heating element 230 or only the atomizing core 220 to heat and atomize the atomizing medium 50 in the oil cup 210, which is not limited hereto. However, providing the heating element 230 and the atomizing core 220 at the same time is more conducive to quickly heating and atomizing the solid or semi-solid atomizing medium 50.

When the aerosol generating device 10 is held by the user in a horizontal direction shown in FIG. 3 for inhalation (i.e., when an opening of the accommodating cavity 210a faces upward), the atomizing medium 50 in a solid state is converted into a flowable molten state under the preheating action of the heating element 230, and the atomizing medium 50 in the molten state is further heated by the atomizing core 220 to generate an aerosol, and a flow path of the atomizing medium 50 in the molten state is in a vertical direction, and an outflow path of the aerosol is in a horizontal direction. In this case, the atomizing medium 50 in the molten state can enter the atomizing core 220 more smoothly under the action of gravity, and the atomizing medium 50 can be atomized more thoroughly when heated and atomized by the atomizing core 220, thereby reducing the residue of the atomizing medium 50 and avoiding the blockage of the main air channel 401.

Since the mounting position 122 of the sealing member 120 and the main air channel 401 are perpendicular to each other, a space inside the shell 110 can be fully utilized in a flow direction of the atomizing medium 50 to arrange the power supply assembly 300, and the internal structure of the aerosol generating device 10 can be more compact, thereby making the outline of the aerosol generating device 10 more compact and flatter.

Further, in a more specific embodiment, referring to FIGS. 5 and 8, the oil cup 210 includes a first connecting portion 211 and a second connecting portion 212 that are coaxially connected and integrally formed. The heating element 230 is sleeved on an outer peripheral surface of the first connecting portion 211. The first cavity 210b is provided in the first connecting portion 211. The second cavity 210c is provided in the second connecting portion 212. In this way, since the heating element 230 is sleeved at the corresponding position of the oil cup 210 for accommodating the atomizing medium 50, the atomizing medium 50 can be sufficiently preheated, thereby accelerating the atomizing medium 50 to be converted from the solid state into the molten state.

Further, in order to enable the oil cup 210 to be fixedly mounted in the mounting position 122 without moving arbitrarily in an axial direction thereof, referring to FIGS. 4, 5 and 8, the outer peripheral surface of the oil cup 210 has a first step 213 surrounding a central axis thereof. Correspondingly, the sealing member 120 has a first limiting structure 123 surrounding a central axis of the oil cup 210 (i.e., a central axis of the mounting position 122) on an inner peripheral surface of the mounting position 122. An end surface of the first limiting structure 123 abuts against the first step 213 to restrict the oil cup 210 from moving in an axial direction defined by the central axis away from the air inlet 120a.

In another embodiment, as shown in FIG. 9, an inner peripheral surface of the first limiting structure 123 is provided with a second limiting structure 124. An end surface of the second limiting structure 124 abuts against one end of the atomizing core 220, to restrict the atomizing core 220 from moving in the axial direction toward the air inlet 120a, thereby limiting the displacement of the entire oil cup 210 toward the air inlet 120a.

In the embodiment shown in FIG. 9, second limiting structures 124 are provided, each of which is strip-shaped. The second limiting structures 124 are spaced apart and surrounds the central axis of the mounting position 122. It should be understood that the number of the second limiting structures 124 is not limited, the number of the second limiting structures 124 may be only one, and the one second limiting structure 124 surrounds the central axis of the mounting position 122 in an annular shape, which is not limited hereto.

Further, as shown in FIGS. 4 and 5, the outer periphery of the oil cup 210 further has a second step 214 surrounding the central axis thereof, the second step 214 is opposite to the first step 213, and is spaced apart from the first step 213 in the axial direction. Correspondingly, the sealing member 120 has a third limiting structure 125 on the inner peripheral surface of the mounting position 122 and surrounding the central axis. The third limiting structure 125 is provided at an opening of the mounting position 122, and is spaced apart from the first limiting structure 123 in the axial direction. The third limiting structure 125 abuts against the second step 214, to restrict the oil cup 210 from moving in the axial direction away from the air inlet 120a. In this way, the displacement of the oil cup 210 in the axial direction is completely restricted, and the oil cup 210 can be fixedly mounted in the mounting position 122 of the sealing member 120.

Similarly, as shown in FIGS. 4 and 5, in order to completely limit the displacement of the atomizing core 220 in the axial direction, an inner wall of the oil cup 210 (i.e., a side wall of the accommodating cavity 210a) is provided with a limiting portion 215 surrounding the central axis of the oil cup 210. The limiting portion 215 is annular and abuts against an end of the atomizing core 220 away from the second limiting structure 124, to restrict the atomizing core 220 from moving in the axial direction away from the air inlet 120a, and the displacement of the atomizing core 220 in the axial direction can also be completely limited.

Through the above arrangement, the sealing member 120 has a simple structure, the oil cup 210 can be firmly fixed in the sealing member 120, and the mounting process of the aerosol generating device 10 is also simplified, and the number of components is reduced, thereby facilitating the mounting of the oil cup 210. Compared with related art in which multiple sealing members 120 are provided to seal the oil cup 210, the oil cup 210 can be better fixed and sealed in the sealing member 120, and the sealing effect is improved.

The power supply assembly 300 includes a battery 310 and a control board 320 electrically connected to the battery 310. The control board 320 is electrically connected to the heating element 230 and the heating member of the atomizing core 220. The battery 310 is configured to store electrical energy, and the control board 320 is configured to control the battery 310 to supply power to the heating element 230 and the heating member and to control the logical on and off of a circuit, which will not be described in detail here.

It should be noted that, as described in the background, the conventional aerosol generating devices 10 have no temperature control function, and the heat generated by the heating element 230 each time is approximately constant. As the remaining amount of atomizing medium 50 changes or the ambient temperature changes, the temperature of the atomizing medium 50 cannot be within an optimal temperature range for melting. This will cause the atomizing medium 50 to fail to melt due to the low heating temperature, or cause the atomizing medium 50 to boil and leak out of the housing 100 due to the high heating temperature, thereby causing the aerosol generating device 10 to be unable to work normally.

Therefore, in order to solve this problem, in an embodiment, referring to FIGS. 6 and 7, the aerosol generating device 10 further includes a temperature sensing element 250 provided on the heating element 230 and communicatively connected to the control board 320 of the power supply assembly 300. The temperature sensing element 250 is configured to acquire a temperature change parameter of the oil cup 210, and the control board 320 of the power supply assembly 300 can control a power supplied to the heating element 230 according to the temperature change parameter of the oil cup 210, thereby controlling a temperature of the atomizing medium 50 when the heating element 230 heats the oil cup 210.

In one embodiment, the temperature sensing element 250 is a thermistor. When the heating element 230 generates heat to heat the oil cup 210, the temperature change parameter of the oil cup 210 changes, and a resistance value of the thermistor changes correspondingly. The control board 320 of the power supply assembly 300 can determine the temperature of the oil cup 210 according to the change of the resistance value of the thermistor and control an output power of the heating element 230. For example, when the heating element 230 begins to heat the oil cup 210, the temperature of the oil cup 210 is relatively low, and the control board 320 can control the heating element 230 to heat the oil cup 210 with a higher power. When the temperature of the oil cup 210 reaches a preset value, the control board 320 can control the heating element 230 to heat the oil cup 210 with a lower power, and the power supply assembly 300 can control the power supplied to the heating element 230 according to the temperature change parameter of the oil cup 210.

As such, when the temperature of the atomizing medium 50 in the oil cup 210 is low, the power supply assembly 300 can control the heating element 230 to heat the oil cup 210 with a higher power. When the temperature of the oil cup 210 approaches or has reached a preset temperature, the heating power of the heating element 230 is controlled, and the temperature of the atomizing medium 50 is within a temperature range suitable for melting, which can effectively prevent the atomizing medium 50 from failing to melt due to the low temperature, or from boiling and causing liquid leakage due to the high temperature, thereby preventing the aerosol generating device 10 from being unable to work normally.

In one embodiment, the temperature sensing element 250 may be welded to the heating element 230 by a surface-mount technique, or may be fixed to the oil cup 210 together with the heating element 230 through the first adhesive layer 240. As for the connection mode between the temperature sensing element 250 and the control board 320, since the heating element 230 is welded with a wire connected to the control board 320, the temperature sensing element 250 can be electrically connected to the control board 320 through the wire connected to the control board 320, or the temperature sensing element 250 can be electrically connected to the control board 320 through a wire directly.

Further, in an embodiment, as shown in FIG. 7, the atomizing assembly 200 further includes a thermal insulator 260, which is attached to the side of the heating element 230 away from the oil cup 210 and covers the heating element 230. The thermal insulator 260 is used to prevent the oil cup 210 from losing heat too quickly after being heated by the heating element 230. In order to ensure the detection accuracy of the temperature sensing element 250, the temperature sensing element 250 is located between the thermal insulator 260 and the heating element 230, and the temperature sensing element 250 can acquire the temperature change parameter of the oil cup 210 without losing heat too quickly, thereby ensuring the detection accuracy of the temperature sensing element 250.

Further, in order to prevent the thermal insulator 260 from being easily removed, similar to the fixing manner of the heating element 230, the thermal insulator 260 can also be adhered to the heating element 230 by a glue. In one embodiment, as shown in FIG. 7, a side of the thermal insulator 260 away from the heating element 230 is covered by a second adhesive layer 270, such as an adhesive tape, a double-sided tape, a solid adhesive, etc., and the thermal insulator 260 is fixed to the heating element 230 by the second adhesive layer 270.

It should be noted that in some other embodiments, the thermal insulator 260 can be omitted, as long as the control board 320 can increase the heating power of the heating element 230 to offset the heat loss, which can also achieve the same effect as providing the thermal insulator 260.

The above-mentioned embodiments do not constitute a limitation on the protection scope of the embodiments. Any modifications, equivalent replacements and improvements made within the spirit and principles of the above-mentioned embodiments shall be included within the protection scope of this embodiment.

The foregoing descriptions are merely specific embodiments of the present disclosure, but are not intended to limit the protection scope of the present disclosure. Any variation or replacement in the art within the scope disclosed in the present disclosure shall all fall within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be subject to the protection scope of the appended claims.
