For this reason, a liquid-core separation structure is designed in the related art, that is, a pull-type separation structure is used. However, in the existing design, the stroke for switching from separated liquid core to the combined liquid core is relatively long, thereby affecting the boundary dimension of the atomizer. Therefore, the related art cannot meet our needs.

DETAILED DESCRIPTION

Technical solutions of embodiments of the present disclosure will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the embodiments described herein are merely some embodiments, rather than all embodiments, of the present disclosure. All other embodiments obtained based on the embodiments described herein by those skilled in the art without creative efforts shall fall within the protection scope of the present disclosure.

In the related art, an electronic atomization device includes an atomizer and a power supply assembly. The power supply assembly is configured to power the atomizer. The atomizer includes a liquid storage member and an atomization assembly. The liquid storage member defines an atomization cavity. The atomization assembly includes a liquid guiding element and a heating element. The liquid guiding element is in communication with the liquid storage cavity and the heating element. A liquid substrate stored in the liquid storage cavity is continuously provided to the heating element by means of capillary action of the liquid guiding element. With the decrease of the residual amount of the liquid substrate inside the liquid storage cavity, the air pressure inside the liquid storage cavity is reduced, thereby reducing the rate at which the liquid substrate inside the liquid storage cavity is provided to the liquid guiding element. Thus, when there is a relatively large amount of liquid substrate in the liquid storage cavity, the liquid guiding element supplies liquid to the heating element at a relatively high rate, resulting in the heating element being flooded by the liquid substrate and thereby causing problems such as gurgling noise, splashing, and leakage during inhalation. Conversely, when there is a relatively small amount of liquid substrate in the liquid storage cavity, the liquid guiding element supplies liquid to the heating element at a relatively low rate, resulting in technical problems such as a burnt core and unsmooth inhalation of the atomization assembly in the process of heating the liquid substrate.

In a second aspect, the present disclosure further provides an electronic atomization device. The electronic atomization device includes an atomizer and a power supply assembly. The power supply assembly is configured to power the atomizer. The atomizer includes a first liquid storage member and an atomization assembly. The first liquid storage member defines a first liquid storage cavity. A liquid substrate is stored in the first liquid storage cavity. The atomization assembly is connected to the first liquid storage member. The atomization assembly includes an atomization core assembly. The atomization core assembly is communicable with the first liquid storage member.

Referring to FIG. 1 to FIG. 12, the embodiments of the present disclosure provide an atomizer. The atomizer includes a first liquid storage member 430 and an atomization assembly 420. The first liquid storage member 430 is configured to store an aerosol substrate. The atomization assembly 420 is connected to the first liquid storage member 430. The atomization assembly 420 includes a support 1 and an atomization core assembly 421 disposed in the support 1. The first liquid storage member 430 is provided with a first sealing member 2. The support 1 is provided with a connecting tube 11. The connecting tube 11 is configured to release sealing of the first sealing member 2 under action of an external force, to enable the atomization core assembly 421 to be in communication with the first liquid storage member 430 through the connecting tube 11.

The first liquid storage member 430 is pre-assembled with and connected to the atomization assembly, and the atomizer is in a liquid-core separation state, so that an aerosol substrate can be prevented from penetrating into the atomization assembly or leaking out from a gap between the first liquid storage member 430 and the atomization assembly, thereby maintaining the freshness of the aerosol substrate and facilitating replacement, maintenance, and cleaning. When the atomizer is required to be used, the atomizer can be switched to the liquid-core combination state, by applying the external force on the connecting tube 11 to release the sealing of the first sealing member 2. Compared with the related art, the atomizer has a simple structure, thereby reducing the stroke required for switching from the liquid-core separation state to the liquid-core combination state, preventing the liquid-core separation structure from affecting the boundary dimension of the atomizer, and improving the use experience of a user.

As illustrated in FIG. 4 to FIG. 8, the first sealing member 2 includes a body portion 21 and a sealing portion 22. The body portion 21 defines a first channel 211. The sealing portion 22 is disposed in the first channel 211. The connecting tube 11 is configured to push the sealing portion 22 out of the first channel 211 under action of the external force, to release the sealing of the first sealing member 2. Compared with a solution in which a pull-type separation structure is adopted in the related art, the solution in which the sealing portion 22 is disengaged to release the sealing in the present disclosure, is convenient for switching from the liquid-core separation state to the liquid-core combination state, and has a short switching stroke. Therefore, the solution in the present disclosure conforms to ergonomic design, ensures the integrity of the product appearance, and enhances improves the aesthetic appearance of the product.

The atomization core assembly 421 includes an atomization core 200. The sealing portion 22 is disengaged from the first channel 211, and the atomization core 200 is in communication with the first liquid storage member 430 through the connecting tube 11. Therefore, the aerosol substrate in the first liquid storage member 430 can flow into the atomization core 200 through the connecting tube 11, so that the atomization core 200 is atomized.

The first channel 211 is provided with multiple ribs 212 therein. The ribs 212 can enhance the sealing of the first sealing member 2, so that the body portion 21 and the sealing portion 22 are tightly connected, thereby preventing leakage of the aerosol substrate, maintaining the freshness of the aerosol substrate, and facilitating replacement, maintenance, and cleaning. In addition, when switching to the liquid-core combination state, the connecting tube 11 is inserted into the first channel 211, and the ribs 212 can also enhance the sealing of the connection between the first liquid storage member 430 and the atomization assembly, so that the aerosol substrate can be prevented from penetrating into the atomization assembly or leaking out from a gap between the first liquid storage member 430 and the atomization assembly, thereby improving the use experience of a user.

The body portion 21 and the sealing portion 22 are connected by a connecting portion 23. The connecting portion 23 can connect the body portion 21 and the sealing portion 22. Therefore, the aerosol substrate in the first liquid storage member 430 is avoided from floating around after the sealing portion 22 is disengaged from the first channel 211, and thus liquid sloshing noise during user operation can be avoided. In addition, the blockage of the connecting tube 11 caused by the sealing portion 22 moving to the connecting tube 11 can be avoided, thereby improving the stability of the atomizer and the meeting the requirements of the user.

As illustrated in FIG. 4 to FIG. 8, and FIG. 10, the first liquid storage member 430 includes a first housing 3. The first housing 3 defines a mounting hole 31 for mounting of the first sealing member 2. The mounting hole 31 provides a mounting position for the first sealing member 2, so as to ensure the stability of the mounting of the first sealing member 2. When in the liquid-core separation state, the first sealing member 2 can seal the mounting hole 31, thereby preventing leakage of the aerosol substrate in the first liquid storage member 430, maintaining freshness of the aerosol substrate, and facilitating replacement, maintenance, and cleaning.

The first housing 3 further defines a first slot 32 located around the mounting hole 31. The body portion 21 is provided with a snap portion 213 for being snap-fitted in the first slot 32. The first slot 32 is connected to the snap portion 213, so that the axial movement of the first sealing member 2 can be limited. That is, when the connecting tube 11 is inserted into the first channel 211, the movement of the first sealing member 2 is prevented to ensure that the body portion 21 seals the first liquid storage member 430 and the atomization assembly, and the aerosol substrate is prevented from penetrating into the atomization assembly or leaking out from a gap between the first liquid storage member 430 and the atomization assembly. Meanwhile, by limiting the axial movement of the first sealing member 2, it is also convenient for the connecting tube 11 to release the sealing portion 22 from the first channel 211 under action of an external force, thereby reducing the stroke required for switching from the liquid-core separation state to the liquid-core combination state, and preventing the liquid-core separation structure from affecting the boundary dimension of the atomizer.

The mounting hole 31 is provided with a flange 33 therein. The sealing portion 22 is provided with a turned edge 221. The turned edge 221 abuts against the flange 33 during sealing. During sealing, the turned edge 221 is located between the flange 33 and the body portion 21, so that the stability of sealing between the sealing portion 22 and the body portion 21 can be enhanced, thereby preventing the sealing portion 22 from disengaging from the first channel 211 when the atomizer is in the pre-assembled state, preventing leakage of the aerosol substrate, maintaining freshness of the aerosol substrate, and facilitating replacement, maintenance, and cleaning.

As illustrated in FIG. 4 to FIG. 9, the connecting tube 11 defines a liquid guiding channel 12 therein. The liquid guiding channel 12 is provided with liquid guiding cotton 4 therein. When in the liquid-core combination state, the aerosol substrate in the first liquid storage member 430 can be continuously transferred to the atomization core 200 by the liquid guiding cotton 4, thereby avoiding problems such as a burnt core and dry burning caused by insufficient supply of the aerosol substrate.

One end of the connecting tube 11 for pushing the sealing portion 22 to disengage from the first channel 211 further defines a notch 13. When in the liquid-core combination state and the sealing portion 22 accidentally blocks the liquid guiding channel 12, the aerosol substrate can still enter the atomization core 200 through the notch 13, thereby further avoiding problems such as the burnt core and dry burning caused by insufficient supply of the aerosol substrate.

As illustrated in FIG. 4 to FIG. 7 and FIG. 11 to FIG. 12, the first liquid storage member 430 is pre-assembled with the atomization assembly by a connecting assembly, to enable the atomizer to be in a pre-assembled state. When in the pre-assembled state, the liquid-core separation state can be maintained, and the pre-assembled stroke is limited, so that the liquid-core separation failure caused by easy displacement of the first liquid storage member 430 can be prevented. Therefore, the aerosol substrate can be prevented from penetrating into the atomization assembly or leaking out from a gap between the first liquid storage member 430 and the atomization assembly, thereby maintaining the freshness of the aerosol substrate, and facilitating replacement, maintenance, and cleaning. In addition, the pre-assembled state can also be maintained, and there is no need for the user to assemble the atomizer by himself/herself, thereby improving the use experience of the user.

The connecting assembly includes a first snap 5 and a second slot 50. The first snap 5 is disposed on one of the first liquid storage member 430 and the atomization assembly. The second slot 50 is defined on the other of the first liquid storage member 430 and the atomization assembly. When the first snap 5 is snap-fitted with the second slot 50, the atomization assembly and the first liquid storage member 430 are in the pre-assembled state. A third slot 51 is further defined on the other of the first liquid storage member 430 and the atomization assembly. The atomization core assembly 421 includes the atomization core 200. When the first snap 5 is snap-fitted with the third slot 51, the atomization core 200 is in communication with the first liquid storage member 430.

When the first snap 5 is snap-fitted with the second slot 50, the atomizer can be maintained in the liquid-core separation state, so that the pre-assembled stroke is limited, and the liquid-core separation failure caused by easy displacement of the first liquid storage member 430 can be prevented. In addition, when the first snap 5 is snap-fitted with the second slot 50, the atomizer can also be maintained in the pre-assembled state, there is no need for the user to assemble the atomizer, and the atomizer can be switched to the liquid-core combination state by pushing the first liquid storage member 430 or the atomization assembly under action of the external force. Therefore, the structure is simple, switching is convenient, and user experience is improved. Moreover, when the first snap 5 is snap-fitted with the third slot 51, the atomizer can be maintained in the liquid-core combination state, so as to ensure that the aerosol substrate continuously enters the atomization core assembly 421 through the connecting tube 11, thereby avoiding problems such as the burnt core and dry burning caused by insufficient supply of the aerosol substrate.

The first liquid storage member 430 further includes a liquid-cup bottom cover 6. The first snap 5 is provided on the liquid-cup bottom cover 6. The liquid-cup bottom cover 6 is detachably connected to the first housing 3. The first housing 3 is used for storing an aerosol substrate. The atomization assembly further includes a connecting frame 7. The second slot 50 and the third slot 51 are defined on the connecting frame 7. The connecting frame 7 is detachably connected to the support 1. The connecting frame 7 is used for mounting of components, such as a battery, a circuit board, etc.

Referring to FIG. 1 to FIG. 12, based on the described atomizer, the embodiments of the present disclosure further provide an electronic atomization device, which adopts the technical solution as follows.

The electronic atomization device includes the atomizer of each of the described embodiments and a power supply. The power supply is configured to power the atomizer.

In the present disclosure, the first liquid storage member 430 of the electronic atomization device is pre-assembled with and connected to the atomization assembly, and the atomizer is in a liquid-core separation state, so that the aerosol substrate can be prevented from penetrating into the atomization assembly or leaking out from a gap between the first liquid storage member 430 and the atomization assembly. When the atomizer needs to be used, the atomizer can be switched to the liquid-core combination state, by applying the external force on the connecting tube 11 to release the sealing of the first sealing member 2, thereby reducing the stroke required for switching from the liquid-core separation state to the liquid-core combination state, preventing the liquid-core separation structure from affecting the boundary dimension of the atomizer, and improving the use experience of the user.

An electronic atomization device 30 is illustrated in FIG. 13. The electronic atomization device 30 includes an atomizer 400 and a power supply assembly 500. In an embodiment, the atomizer 400 and the power supply assembly 500 are configured to be non-detachably connected to each other, so that the electronic atomizer device 30 is integrally portable. In an embodiment, the atomizer 400 and the power supply assembly 500 are configured to be detachably connected to each other, so that the atomizer 400 is easy to replace, and the power supply assembly 500 can be continuously used as a main body.

In some embodiments, as illustrated in FIG. 13 to FIG. 17, the housing assembly 301 of the electronic atomization device 30 includes a first housing 311 and a second housing 312. The first housing 311 defines an opening on the right side of the first housing 311. The second housing 312 is connected to the opening on the right side of the first housing 311. The second housing 312 is configured as an L-shaped structure. A part of the atomizer 400 is accommodated in an inner cavity of the first housing 311. The first housing 311 and the second housing 312 together form an accommodating cavity of the power supply assembly 500. The atomizer 400 and the power supply assembly 500 are arranged side by side in a longitudinal axis of the housing assembly 301.

The housing assembly 301 further includes a nozzle 313. The nozzle 313 is connected to a top opening top of the first housing 311. The nozzle 313 further defines a nozzle opening 330. The nozzle opening 330 is configured for aerosol generated by atomization of the atomizer 400 to be discharged therethrough.

The atomizer 400 includes an atomization assembly 420, a first liquid storage member 430, and a first liquid guiding element 440.

The atomization assembly 420 includes a second liquid storage member 422 and an atomization core assembly 421. The second liquid storage member 422 defines a second liquid storage cavity 4221. The atomization core assembly 421 is disposed in the second liquid storage cavity 4221.

The atomization core assembly 421 includes a heating element 411, a second liquid guiding element 412, an atomization support 413, and a ventilation tube 414.

The heating element 411 includes a heating portion 4111 and an electrical connection portion 4112. The heating portion 4111 is configured as a heating sheet having a grid structure. The electrical connection portion 4112 is configured as two connection pins. The two connection pins are connected to the heating sheet at two sides of the heating sheet.

The second liquid guiding element 412 is made of a fiber cotton material. The second liquid guiding element 412 defines a hollow inner cavity. The heating element 411 is fixed in the inner cavity of the second liquid guiding element 412. The electrical connection portion 4112 of the heating element 411 extends out of the atomizer 400 and is electrically connected to the power supply assembly 500, so that the power supply assembly 500 can power the heating element 411.

The atomization support 413 defines a hollow inner cavity. The second liquid guiding element 412, in which the heating element 411 is fixed, is fixed in the inner cavity of the atomization support 413. The second liquid guiding element 412 is further provided with a protrusion. The atomization support 413 defines a notch on one side of the atomization support 413. The protrusion of the second liquid guiding element 412 is fixed to the notch of the atomization support 413, so as to facilitate positioning of the second liquid guiding element 412.

The vent tube 414 is connected to one end of the atomization support 413 close to the nozzle 313. The aerosol generated by atomization of the atomization core assembly 421 enters the interior of the nozzle opening 330 through the atomization support 413 and the vent tube 414, and is then discharged from the nozzle.

In alternative other embodiments, the atomization core assembly 421 may be a ceramic core atomization assembly or other structure of a cotton core atomization assembly. Details are not repeated in the embodiments of the present disclosure.

The first liquid storage member 430 is connected to the housing assembly 301, and is located at the right side of the first housing 311 and above the second housing 312. The first liquid storage member 430 defines a first liquid storage cavity 431. The first liquid storage cavity 431 is configured for storing of a liquid substrate. The first liquid storage member 430 may be fixedly connected to the housing assembly 301, or the first liquid storage member 430 may be detachably connected to the housing assembly 301. The first liquid storage member 430 and the atomization assembly 420 are arranged side by side in the length direction of the housing assembly 301. The length direction of the housing assembly 301 is an X direction as illustrated in FIG. 15. Therefore, the internal structural design of the electronic atomization device 30 can be optimized, and the liquid substrate inside the first liquid storage member 430 can be facilitated to be rapidly provided to the atomization assembly 420 for atomization.

The first liquid guiding element 440 is made of a fiber cotton material. The first liquid guiding element 440 is configured to communicate the atomization assembly 420 with the first liquid storage cavity 431, so that the liquid substrate inside the first liquid storage cavity 431 is provided to the atomization assembly 420 through the first liquid guiding element 440.

As illustrated in FIG. 19, the first liquid guiding element 440 further defines a first gas guiding channel 441. The first gas guiding channel 441 is in communication with the first liquid storage cavity 431 and the second liquid storage cavity 4221. The first gas guiding channel 441 includes a first gas guiding groove defined on the first liquid guiding element 440. The first liquid guiding element 440 is configured as a rod. The first gas guiding groove extends from a top end face of the first liquid guiding element 440 to a bottom end face of the first liquid guiding element 440.

It can be understood that since the first liquid guiding element 440 defines the first gas guiding channel 441 and the first gas guiding channel 441 is in communication with the first liquid storage cavity 431 and the second liquid storage cavity 4221, the air pressure inside the first liquid storage cavity 431 does not change with the consumption of the liquid substrate inside the first liquid storage cavity 431, so that the rate at which the first liquid guiding element 440 supplies liquid to the atomization assembly 420 is maintained relatively stable, thereby effectively preventing the following problems. When the residual amount of the liquid substrate inside the first liquid storage cavity 431 is sufficient, the first liquid guiding element 440 supplies an excessive amount of the liquid substrate to the atomization core assembly 421, causing the heating element 411 to be submerged in the liquid substrate and resulting in problems such as gurgling noise, splashing, and leakage during inhalation. When the residual amount of the liquid substrate inside the liquid storage cavity is relatively low, the rate at which the liquid guiding element supplies liquid to the heating element is relatively slow, resulting in technical problems such as a burnt core and unsmooth inhalation of the atomization assembly in the process of heating the liquid substrate.

In some embodiments, with continued reference to FIG. 14 and FIG. 15, the atomization assembly 420 further includes a liquid storage element 423. The liquid storage element 423 is disposed in the second liquid storage cavity 4221, and is configured to be arranged around the atomization core assembly 421. The liquid storage element 423 is made of a polymer fiber cotton material. One end of the first liquid guiding element 440 extends into the first liquid storage cavity 431, and the other end of the first liquid guiding element 440 extends into the second liquid storage cavity 4221, so that the liquid substrate is supplied to the liquid storage element 423 and further supplied to the atomization core assembly 421.

In some embodiments, as illustrated in FIG. 14 and FIG. 18, the liquid storage element 423 defines a second gas guiding channel 4233. The second gas guiding channel 4233 is in communication with the first gas guiding channel 441 and the nozzle opening 330. In a specific embodiment, there are multiple second gas guiding channels 4233. The liquid storage element 423 is configured as a rod. The multiple second gas guiding channels 4233 are configured as multiple second gas guiding grooves. The second gas guiding grooves each extend from a top end face of the liquid storage element 423 to a bottom end face of the liquid storage element 423. The liquid storage element 423 abuts against, in a circumferential direction of the liquid storage element 423, an inner wall of the second liquid storage member 422. The multiple second gas guiding channels 4233 are defined between the multiple second gas guiding grooves and the inner wall of the second liquid storage member 422, respectively. The top of the second gas guiding channel 4233 is in communication with the nozzle opening 330, and the second gas guiding channel 4233 is also in communication with the first gas guiding channel 441.

It can be understood that, when the user does not perform an inhalation action, the first liquid storage cavity 431 of the first liquid storage member 430 is in communication with the second liquid storage cavity 4221 of the second liquid storage member 422, and is in communication with the outside through the nozzle opening 330. Thus, the first liquid storage cavity 431 and the second liquid storage cavity 4221 are in a state of air pressure equilibrium, and no siphon effect occurs between the first liquid storage cavity 431 and the second liquid storage cavity 4221. Consequently, the first liquid guiding element 440 cannot transfer the liquid substrate inside the first liquid storage cavity 431 to the second liquid storage cavity 4221, thereby effectively solving the problem of leakage. When the user performs an inhalation action, a negative pressure is generated at the nozzle opening 330, thereby causing a negative pressure in the second liquid storage cavity 4221. At this time, the pressure inside the first liquid storage cavity 431 is greater than the pressure inside the second liquid storage cavity 4221, and the siphon effect occurs between the second liquid storage cavity 4221 and the first liquid storage cavity 431 due to the pressure difference, so that the first liquid guiding element 440 can transfer the liquid substrate inside the first liquid storage cavity 431 to the second liquid storage cavity 4221. With each inhalation by the user, a single liquid siphon effect occurs, thereby pushing the liquid substrate from the first liquid storage cavity 431 to the second liquid storage cavity 4221 through the first liquid guiding element 440. Since the liquid substrate consumed by the user for each inhalation can be replenished by the siphon effect, the liquid guiding rate of the first liquid guiding element 440 remains substantially constant.

To further enhance the siphon effect between the second liquid storage cavity 4221 and the first liquid storage cavity 431, the liquid storage element 423 defines multiple second gas guiding grooves, the first liquid guiding element 440 defines one first gas guiding groove, and the multiple second gas guiding grooves are defined at intervals in the circumferential direction of the liquid storage element 423, thereby facilitating the formation of a uniform negative pressure inside the second liquid storage cavity 4221. In addition, the depth of each second gas guiding groove is larger than the depth of the first gas guiding groove. The width of each second gas guiding groove is larger than the width of the first gas guiding groove. For example, the depth of the first guiding groove is 0.5 mm, the width of the first guiding groove is 0.8 mm, the depth of the second guiding groove is 1.0 mm, and the width of the second gas guiding groove is 2.4 mm. Consequently, during inhalation at the nozzle opening 330, the negative pressure generated in the multiple second gas guiding grooves is much greater than the negative pressure generated in the first gas guiding grooves, thereby enhancing the siphon effect between the second liquid storage cavity 4221 and the first liquid storage cavity 431.

The first liquid storage member 430 and the second liquid storage member 422 are arranged side by side in the length direction of the housing assembly 301. The first liquid guiding element 440 is fixed in the transverse axial direction of the housing assembly 301. In a specific embodiment, the liquid storage element 423 is made of a rigid polymer fiber cotton material. The liquid storage element 423 defines a fixing hole 4231. The other end of the first liquid guiding element 440 is fixed in the fixing hole 4231. The liquid storage element 423 further includes a through hole 4232. The atomization core assembly 421 is fixed in the through hole 4232. The through hole 4232 extends in the longitudinal direction of the housing assembly 301. The fixing hole 4231 extends in the transverse direction of the housing assembly 301. Since the first liquid guiding element 440 is fixed in the fixing hole 4231 of the liquid storage element 423, the liquid substrate stored in the first liquid guiding element 440 can be directly transferred to the liquid storage element 423. An inner diameter of the fixing hole 4231 is smaller than an outer diameter of the first liquid guiding element 440, so that the first liquid guiding element 440 is in interference fit with the fixing hole 4231 of the liquid storage element 423, thereby maintaining a stable connection. For example, the outer diameter of the first liquid guiding element 440 is set to 4.0 mm, and the inner diameter of the fixing hole 4231 is set to 3.8 mm.

In some embodiments, with continued reference to FIG. 15 and FIG. 16, the first liquid guiding element 440 is fixed to one end of the heating portion 4111 of the heating element 411 away from the nozzle opening 330. It can be understood that if the first liquid guiding element 440 is fixed to one side of the heating portion 4111 of the heating element 411 or located above the heating portion 4111, the liquid substrate provided to the heating portion 4111 by the first liquid guiding element 440 may fail to be atomized in time, resulting in splashing.

In some embodiments, with continued reference to FIG. 15 and FIG. 16, the second liquid storage member 422 is provided with a connecting tube 4222. The first liquid storage member 430 is connected to the connecting tube 4222 of the second liquid storage member 422. The first liquid guiding element 440 passes through the connecting tube 4222 and extends into the first liquid storage cavity 431 of the first liquid storage member 430. Therefore, the first liquid guiding element 440 can be stably connected between the first liquid storage cavity 431 and the second liquid storage cavity 4221.

In some embodiments, a volume of the first liquid storage cavity 431 is greater than a volume of the second liquid storage cavity 4221, so that the liquid substrate is mainly stored in the first liquid storage cavity 431, thereby preventing excessive accumulation of the liquid substrate at the atomization core assembly 421 and preventing splashing. It can be understood that the liquid storage volume of the second liquid storage cavity 4221 is only sufficient to meet the volume of the liquid substrate required for one to two continuous inhalations by the user, so that leakage or contact of the liquid substrate with air caused by the excessive liquid substrate stored in the second liquid storage cavity 4221 can be prevented. In a specific embodiment, the volume of the first liquid storage cavity 431 is 15 ml, and the volume of the second liquid storage cavity 4221 is 5 ml.

In some embodiments, with continued reference to FIG. 14 and FIG. 15, the atomizer 400 further includes a sealing seat 424 and an upper sealing seat 425. The sealing seat 424 is connected to an open end of the second liquid storage cavity 4221 away from the nozzle opening 330, and abuts against one end of the liquid storage element 423, so as to seal a lower end of the second liquid storage cavity 4221. The upper sealing seat 425 is connected to an open end of the second liquid storage cavity 4221 close to the nozzle opening 330, so as to seal an upper end of the second liquid storage cavity 4221.

In some embodiments, the atomizer 400 further includes a liquid absorption element 426. The liquid absorption element 426 is made of a fiber cotton material. The liquid absorption element 426 is disposed at the open end of the second liquid storage cavity 4221 close to the nozzle opening 330, so as to absorb the condensate formed inside the vent tube 414 of the atomization assembly 420, thereby preventing the condensate from entering the nozzle opening 330 and then being inhaled by the user.

In some embodiments, the power supply module 500 includes a cell 551, a cell buffer 552, a cell support 553, a control board 554, a connecting plate 555, an airflow sensing switch assembly 556, and a button assembly 557.

The cell 551 is configured to power the heating element 411 of the atomization assembly 400. The electrical connection portion 4112, which is connected to both sides of the heating portion 411 of the heating element 411, is electrically connected to the connecting plate 555. Both the connecting plate 555 and the cell 551 are electrically connected to the control board 554. The cell 551 is fixed in the inner cavity of the housing assembly 301 by means of the cell support 553, and the cell buffer 52 is wrapped around the periphery of the cell 551 to protect the cell 551. The control board 554 is fixed to the cell support 553.

The airflow sensing switch assembly 556 includes an airflow sensing switch 5561 and airflow-sensing-switch fixing seat 5562. The airflow sensing switch 5561 is fixed to the cell support 553 by means of the airflow-sensing-switch fixing seat 5562. The airflow sensing switch 5561 is configured to control the cell 551 to supply power to the heating element 411 of the atomization assembly 420 by detecting a inhalation action.

The button assembly 557 includes a button 5571 and a button fixing seat 5572. The button 5571 is fixed to the button fixing seat 5572. The button component 557 is electrically connected to the control board 554. The button assembly 557 is configured to control on and off of the electronic atomization device.

The electronic atomization device further includes a gas adjusting assembly 600. The gas adjusting assembly 600 is fixed to the bottom of the housing assembly 301. A gas inlet of the electronic atomization device 30 is defined at the bottom of the housing assembly 301. The gas adjusting assembly 600 is configured to adjust the flow rate of the gas inlet. The gas adjusting assembly 600 includes a gas adjusting switch 661 and a gas adjusting seat 662. The gas adjusting switch 661 is fixed to the gas adjusting seat 662. The flow rate of the gas inlet of the electronic atomization device 30 is controlled by controlling an overlapping area of a gas vent on the gas adjusting switch 661 and a gas vent on the gas adjusting seat 662.
