This application claims priority to Chinese Patent Application No. 202111340237.0, filed with the China National Intellectual Property Administration on Nov. 12, 2021 and entitled “ATOMIZATION DEVICE, LIQUID STORAGE DEVICE, AND ATOMIZATION ASSEMBLY”, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

Embodiments of the present invention relate to the field of electronic atomization technologies, and in particular, to an atomization device, a liquid storage device, and an atomization assembly.

BACKGROUND

Since electronic atomization apparatuses do not contain harmful components such as tar and suspended particles in cigarettes, electronic atomization apparatuses are used more and more. When the electronic atomization apparatus is in use, liquid in the atomization apparatus flows from a liquid storage cavity to an atomization core in an atomization device to be atomized to generate smoke, to imitate real smoke.

At present, the liquid storage cavity and the atomization assembly of the electronic atomization apparatus are generally of an integrated structure, and the e-liquid is usually in constant contact with the atomization core, which is likely to cause damage to the atomization core and shorten the service life of the atomization core. In addition, the long-term contact of the e-liquid with the atomization core will easily lead to leakage of the e-liquid, which greatly degrades the user experience.

In the prior art, there has been a method of separating the e-liquid from the core (that is, the atomization core is separated from or not in contact with the e-liquid) to resolve such problems. For example, as an example of the prior art, Patent No. CN201420372002.9 provides an atomization apparatus which can separate the e-liquid from the core. The atomization apparatus includes an atomization sleeve and an atomization assembly located in the atomization sleeve. An e-liquid storage cup for storing e-liquid is detachably mounted in the atomization sleeve. One end of the e-liquid storage cup is provided with a sealing structure for sealing the e-liquid, and a piercing structure suitable for piercing the sealing structure when the e-liquid storage cup is pushed in to allow the e-liquid to enter the atomization assembly is further arranged in the atomization sleeve.

In Embodiment 1, referring toFIG.1andFIG.2,FIG.1andFIG.2show a schematic three-dimensional diagram in a direction and a schematic exploded diagram from a perspective of an atomization device100according to Embodiment 1 of the present invention respectively. The atomization device100is used for being combined with a power supply mechanism (not shown) to form an electronic atomization apparatus. The atomization device100includes a liquid storage device10, an atomization assembly20, and a bottom cover30. The atomization assembly20is provided with a clamping portion201, the bottom cover30is correspondingly provided with a clamping groove31corresponding to the clamping portion201, and the bottom cover30is fixedly connected to the atomization assembly20through clamping between the clamping groove31and the clamping portion201, to prevent atomization components inside the atomization assembly20from falling off from the bottom. The liquid storage device10stores a liquid matrix that may be atomized to generate an aerosol, and the atomization device100includes a first electrode contact70aand a second electrode contact70bthat are collaboratively connected to the power supply mechanism. When a user uses the atomization device100, the power supply mechanism may provide electric energy to the atomization device100through the first electrode contact22aand the second electrode contact22b, so that the atomization device100may heat the liquid matrix to volatilize at least one part of ingredients of the liquid matrix to generate the aerosol that may be provided for the user.

For the foregoing liquid storage device10, continue to refer toFIG.3toFIG.5.FIG.3toFIG.5show a schematic three-dimensional diagram in a direction of the liquid storage device, a schematic three-dimensional diagram in another direction of the liquid storage device, and a schematic cross-sectional diagram of the liquid storage device respectively. The liquid storage device10includes a first part11and a second part12, and the first part11and the second part12perform enclosure to form a liquid storage cavity13. It is easily understood that the first part11and the second part12are hermetically connected to each other, so that the liquid storage cavity13may store a liquid matrix that can be atomized. The top of the first part11is provided with a suction nozzle110, the suction nozzle110is provided with a vent hole111, and the vent hole111is used for providing a user of the atomization device10with an inhalation inlet. For ease of inhalation of the user, the vent hole111is provided in a middle position on the top of the first part11.

It is worth noting that the liquid storage device10may alternatively not be divided into the first part11and the second part12, and the liquid storage device10may be integrally formed, for example, may be integrally formed if each of the first part11and the second part12is made of a plastic material. In this embodiment, the first part11is made of a silicone material, and the second part12is made of a plastic material. In an aspect, because the first part11is made of a plastic material, manufacturing costs can be saved. In another aspect, because the suction nozzle110often comes into contact with a mouth of a human body, use of a silicone material can avoid generating a harmful substance for the human body.

The liquid storage device10is further provided with an air conduit112, the air conduit112is arranged inside the liquid storage device10along a length direction of the liquid storage device10, where one end is connected to the vent hole111, and the other end extends to the second part12. An end face of the second part12has a liquid outlet pipe120extending toward the atomization assembly20, and the liquid outlet pipe120as a liquid outlet of the liquid storage device10is used for guiding liquid in the liquid storage device10into the atomization assembly20for atomization. At the same end of the liquid outlet pipe120, the end face of the second part12further has a vent pipe121extending toward the atomization assembly20, there may be two liquid outlet pipes120separately arranged on two sides of the vent pipe121, and the vent pipe121has one end connected to the air conduit112in the liquid storage device10and the other end connected to the atomization assembly20, so that smoke atomized by the atomization assembly20is transmitted to the air conduit112through the vent pipe121, and then transferred to the vent hole111through the air conduit112to allow the user to inhale. The liquid outlet pipe120and the vent pipe121are configured into a pluggable hollow cylindrical shape, to facilitate plugging with the atomization assembly20to form a liquid guide passage and an air transmission passage.

One end of the liquid outlet pipe120facing the atomization assembly20is provided with a sealing film1201, and the sealing film1201as a first seal is used for sealing the liquid outlet pipe120, thereby sealing the atomizable liquid matrix in the liquid storage cavity13of the liquid storage device10. When the sealing film1201is broken, the liquid in the liquid storage device10may flow from the liquid outlet pipe120into the atomization assembly20. It is easily understood that another manner may also be adopted for the first seal. As shown inFIG.6,FIG.6shows another embodiment of the first seal. A liquid outlet end of the liquid outlet pipe120is provided with a silicone plug or rubber plug1202, and the silicone plug or rubber plug1202is tightly plugged into the liquid outlet pipe120. When the silicone plug or rubber plug1202is partially propped open or released under an external force action, there is a gap between the silicone plug or rubber plug1202and the liquid outlet pipe120, and the liquid in the liquid storage device10may flow towards the atomization assembly20along the gap.

It is worth noting that because the liquid outlet pipe120of the liquid storage device10is sealed by the first seal, the liquid storage device10may independently perform storage or operating, and therefore the liquid storage device10is detachably connected to the atomization assembly20. For example, when use is required, the liquid storage device10and the atomization assembly20may be assembled together; and during storage, the liquid storage device10and the atomization assembly20may be stored independently and separately, to avoid long-term contact of the liquid matrix in the liquid storage device10with the atomization assembly20.

For the foregoing second part12, continue to refer toFIG.3. The second part12is provided with a snap-fit member123, and the snap-fit member123is used for forming fixed connection to a snap-fit position matching the atomization assembly20, to enable the liquid storage device10to be assembled to the atomization assembly20, so that the second part12as a connection end connects the liquid storage device10to the atomization assembly20. It is easily understood that a snap-fit position may alternatively be arranged on the second part12, and a matching snap-fit member123is arranged on the atomization assembly20.

Continue to refer toFIG.7toFIG.10.FIG.7toFIG.10respectively show a schematic exploded diagram from a perspective of assembling a liquid storage device10to an atomization assembly20, a schematic cross-sectional diagram of a liquid storage device10and an atomization assembly20in a first assembly position, a schematic cross-sectional diagram of a liquid storage device10and an atomization assembly20in a second assembly position, and a schematic three-dimensional diagram in a direction of a support23of an atomization assembly20. The atomization assembly20includes a shell21, a second seal22, a support23, a third seal24, an atomization core25, and a base26are arranged in the shell, and the second seal22, the support23, the third seal24, the atomization core25, and the base26are assembled sequentially along an axial direction of the atomization assembly20.

For the foregoing shell21, the shell21is axially provided with a first snap-fit position211and a second snap-fit position212, and the first snap-fit position211and the second snap-fit position212may be fixedly connected to the snap-fit member123of the liquid storage device10. When the snap-fit member123is clamped to the first snap-fit position211, the atomization assembly20is fixed connected to the liquid storage device10in the first assembly position. In this case, the atomization assembly20is not tightly bound to the liquid storage device10, and there is a specific gap50, as shown inFIG.8. When the atomization assembly20moves to the second snap-fit position212opposite to the liquid storage device10, the atomization assembly20is fixed connected to the liquid storage device10in the second assembly position. In this case, the atomization assembly20is tightly bound to the liquid storage device10, and there is no gap, as shown inFIG.9. It is easily understood that a fixed connection manner of the liquid storage device10and the atomization assembly20is not merely limited to the clamping manner, or may be another manner, for example, magnetically attractive connection. A magnetic member is arranged on one of the liquid storage device10and the atomization assembly20, and a magnetically attractive member matching the magnetic member is arranged on the other, as long as the liquid storage device10is fixedly connected to the atomization assembly20.

Further, to enable the liquid storage device10to move between the first assembly position and the second assembly position when being assembled in the atomization assembly20, a sidewall of the foregoing snap-fit member123is further provided with a first slope1231and a second slope1232, and the first slope1231and the second slope1232are arranged opposite to each other. When the snap-fit member123is snapped into the first snap-fit position211, the second slope1232abuts against an upper end of a partition portion213in the middle of the first snap-fit position211and the second snap-fit position212. An external force acts. For example, the user of the atomization device100presses the liquid storage device10, the second slope1232is under a pressing force, and the liquid storage device10moves downward along the second slope, until the snap-fit member123falls into the second snap-fit position212, thereby moving from the first assembly position to the second assembly position. Similarly, when the snap-fit member123is snapped into the second snap-fit position212, the first slope1231abuts against a lower end of the partition portion213in the middle of the first snap-fit position211and the second snap-fit position212. An external force acts. In this case, the external force is opposite to the foregoing external force, the liquid storage device10bears a pulling force for separating from the atomization assembly20. Under this pull force, the liquid storage device10moves upward along the first slope, until the snap-fit member123falls into the first snap-fit position211, thereby moving the second assembly position to the first assembly position.

The base26is fixedly connected to the support23. In addition, the base26and the support23are fixedly connected to each other to perform enclosure to form an atomization chamber263, and the aerosol generated by the atomization device100is released into the atomization chamber263.

The atomization core25usually includes a capillary liquid guide element251used for absorbing the liquid matrix, and a heating element252bound to the liquid guide element, and the heating element252heats, when being powered on, at least part of the liquid matrix of the liquid guide element251to generate smoke. In an optional embodiment, the liquid guide element251includes flexible fiber, for example, cotton fiber, nonwoven fabric, or glass fiber strand, or includes a porous body with a micropore structure, for example, porous ceramic, is preferably porous ceramic in this embodiment, and is configured as, but not limited to, a roughly block-shaped structure. The heating element252may be bound to the porous body in a manner such as printing, deposition, sintering, or physical assembly, or is wound around the porous body. In another embodiment of the present invention, the atomization core25may alternatively atomize the liquid matrix in an ultrasonic atomization manner, and it is not necessary to atomize the liquid matrix in a heating manner.

Further, as shown inFIG.8, the porous body252is arch-shaped, and has an atomization surface2521facing the bottom cover30along the axial direction of the atomization device100. During use, the porous body252has a side facing away from the atomization surface2521in fluid connection to the liquid storage cavity13and then may absorb the liquid matrix, then the liquid matrix is transmitted by the micropore structure inside the porous body252to the atomization surface2521and is heated and atomized to form an aerosol, and the aerosol is released or escapes to the atomization chamber263from the atomization surface2521. It may be understood that in some other embodiments, the porous body252may be such arranged that its atomization surface2521faces away from an end cover along the axial direction of the atomization device100, thereby facing the suction nozzle110. In this embodiment, the atomization surface2521extends along a cross-sectional direction of the atomization device100.

The porous body252has a first sidewall2522and a second sidewall2523opposite to each other along a thickness direction, and a base part2524between the first sidewall2522and the second sidewall2523; and the first sidewall2522and the second sidewall2523extend along a length direction, then a liquid passage2525is defined between the first sidewall2522and the second sidewall2523, and the liquid passage2525in fluid connection to the liquid storage cavity13and then absorbs the liquid matrix.

Further, as shown inFIG.11, the support23maintains the atomization core25nested with the third seal24. In some embodiments, the support23may be roughly in a shape of a ring whose lower end is an opening, an accommodating cavity60is defined on the support23, and the accommodating cavity60is used for accommodating and maintaining the third seal24and the atomization core25. In an aspect, the third seal24may be between the atomization core25and the support23to seal the gap between them, to prevent the liquid matrix from seeping from the gap between them. In another aspect, a case that the third seal24is located between the atomization core25and the support23helps the atomization core25be stably accommodated in the support23and be prevented from being released. With respect to the specific structure and shape, the third seal24is generally in a shape of a hollow cylinder, and the hollow inside is used for accommodating the porous body252, and is nested outside the porous body252in a tight-fit manner.

The second seal22is arranged between the liquid storage device10and the support23, and the second seal22is correspondingly provided with a first liquid guide hole221and a first ventilation hole222that are docked with the liquid outlet pipe120and the vent pipe121of the liquid storage device10. The support23is provided with a second liquid guide hole231connected to the first liquid guide hole221, where the second liquid guide hole231is used as a liquid inlet through which the liquid matrix flows towards the atomization core25; and a second ventilation hole232connected to the first ventilation hole222. The liquid outlet pipe120and the vent pipe121may be inserted into the second liquid guide hole231and the second ventilation hole232respectively through the first liquid guide hole221and the first ventilation hole222. In addition, the third seal24is provided with a third liquid guide hole241connected to the second liquid guide hole231. Then, when the sealing film1201is broken or the silicone plug1202is removed, the liquid matrix in the liquid storage device10may flow from the liquid storage cavity13in the liquid storage device10through the liquid outlet pipe120, the first liquid guide hole221, the second liquid guide hole231, the third liquid guide hole241, and the liquid passage2525between the first sidewall2522and the second sidewall2523of the porous body252to the atomization core25for heating and atomization (as shown by a path R1inFIG.10), and smoke generated by atomization is transmitted through the second ventilation hole232, the first ventilation hole222, and the vent pipe121to the vent hole111of the liquid storage device and then is inhaled by the user of the atomization device100.

It is worth noting that in this embodiment, the second seal22is flexible and has a specific elastic recovery force, and the hole diameter of the first liquid guide hole221of the second seal22is less than the pipe diameter of the liquid outlet pipe120. Therefore, when the liquid outlet pipe120is inserted into the second liquid guide hole231through the first liquid guide hole221, because the hole diameter of the first liquid guide hole221is less than the pipe diameter of the liquid storage pipe120, and a pipe wall of the liquid outlet pipe120generates a pressing force for an inner wall of the first liquid guide hole221, the first liquid guide hole221tightly wraps the pipe wall of the liquid outlet pipe120under the elastic recovery force, thereby sealing a gap between the outer pipe wall of the liquid outlet pipe120and the inner wall of the first liquid guide hole221, that is, sealing the joint between the liquid inlet and the liquid outlet. Therefore, after the first seal is unsealed, the liquid matrix cannot leak out from the gap between the outer pipe wall of the liquid outlet pipe120and the inner wall of the first liquid guide hole221when the liquid matrix flows from the liquid outlet into the liquid inlet.

For the foregoing support23, continue to refer toFIG.10. The support23is provided with a pressing member233for releasing the sealing action of the seal, the pressing member233extends into the second liquid guide hole231along the length direction of the atomization device100, may be in a shape of a sheet or a pole, and has a free end facing the first seal, and the free end is configured as a pressing end2331used for pressing the first seal. To help the pressing end2331press the seal, the pressing end2331is such arranged that at least one part protrudes from the second liquid guide hole231, to facilitate pressing. In this case, the second seal22surrounds a protruding part of the pressing member233, and the protruding part is surrounded by a hole wall of the first liquid guide hole221. In addition, to cause the pressing member233to have sufficient strength so that the pressing member233can pierce or prop open the first seal, the pressing member233is configured to be at least partially connected to an inner wall of the second liquid guide hole231.

The pressing member233and the inner wall of the second liquid guide hole231jointly define and form a path in which the liquid matrix circulates in the second liquid guide hole231. In another embodiment of the present invention, the second liquid guide hole231may alternatively be defined and formed by the pressing member233itself. Specifically, a through-hole (not shown) may be provided on the pressing member233, and the through-hole is connected to the liquid outlet pipe120. Therefore, after the pressing member233presses the first seal, the liquid matrix flows through the third liquid guide hole241towards the atomization core25for atomization along the through-hole.

To sum up, because the atomization assembly20has the first assembly position and the second assembly position relative to the liquid storage device10, the atomization device100may have such two states as a pre-assembly state and a use state. In both the pre-assembly state and the use state, the atomization assembly20is connected to the liquid storage device10. When the atomization assembly20is connected to the liquid storage device10in the first assembly position, the atomization device is in the pre-assembly state; and when the atomization assembly20moves from the first assembly position to the second assembly position relative to the liquid storage device10, the atomization device is in the use state.

In the pre-assembly state, that is, when the atomization assembly20is connected to the liquid storage device10in the first assembly position, the atomization assembly20is not tightly bound to the liquid storage device10, and there is a specific gap50. In this case, the pressing member233and the first seal are spaced apart from each other by a specific spacing, the first seal has not been broken or released, and the liquid matrix is sealed in the liquid storage cavity in the liquid storage device10, and is separated from the atomization core25of the atomization assembly20, as shown inFIG.8. It is easily understood that in another embodiment of the present invention, in the pre-assembly state, the pressing member233may alternatively abut against the first seal, as long as the first seal is not unsealed in the pre-assembly state.

In the use state, that is, when the user prepares to use the atomization device100for inhalation, the user may apply pressure to the liquid storage device10, so that the atomization assembly20moves from the first assembly position to the second assembly position under an external force relative to the liquid storage device10. In this case, the atomization assembly20is tightly bound to the liquid storage device10, and the pressing member233further presses the first seal, so that the first seal is broken or released, and then the liquid matrix in the liquid storage device10flows towards the atomization core25in the atomization assembly20for atomization.

By comparing the foregoing manner with the existing technology in which the liquid matrix in the liquid storage device10is in direct contact with the atomization core25, for the atomization device100provided in this embodiment of the present invention, before the atomization device100is used for inhalation, the liquid matrix in the atomization device100is sealed in the liquid storage device10and is separated from the atomization core25; and is unsealed and comes into contact with the atomization core25only during use, which greatly reduces a contact time of the liquid matrix and the atomization core25and can effectively prevent e-liquid from leaking.

In addition, In the atomization device provided in the embodiments of this application, the second seal is arranged on the atomization assembly, and when the liquid storage device is connected to the atomization assembly, the pressing member of the atomization assembly provides a pressing force for the first seal of the liquid storage device, to break or release the first seal, so that the liquid matrix in the liquid storage device flows from the liquid outlet of the liquid storage device towards the liquid inlet of the atomization assembly; and the second seal seals the joint between the liquid outlet and the liquid inlet, to seal a gap at the joint between the liquid outlet and the liquid inlet, so that the liquid matrix cannot leak out during unsealing of the first seal.

In Embodiment 2,FIG.12andFIG.13show a schematic three-dimensional diagram in a direction and a schematic exploded diagram from a perspective of an atomization device200according to another embodiment of the present invention. The atomization device200includes a liquid storage device10a, an atomization assembly20a, and a bottom cover30a, the liquid storage device10aincludes a vent hole11a, a liquid storage cavity12a, and an air conduit13athat are the same as those in Embodiment 1, an end of the liquid storage device10aopposite to a vent hole111aof the liquid storage device is open, and the atomization assembly20amay be mounted in the liquid storage device10athrough the open end of the liquid storage device10a.

A shell of the bottom cover30ais provided with a first snap-fit position31aand a second snap-fit position32a, and a shell of the liquid storage device10ais provided with a snap-fit member14amatching the first snap-fit position3la and the second snap-fit position32a. When the snap-fit member14ais in snap-fit connection to the first snap-fit position31a, the bottom cover30aand the liquid storage device10aare mutually assembled in the first assembly position. In this case, the bottom cover30aand the liquid storage device10astill maintain a gap50abetween them and are not completely tightly bound to each other, as shown inFIG.13. When the bottom cover30ais further pushed to cause the snap-fit member14ato be in snap-fit connection to the second snap-fit position32a, the bottom cover30aand the liquid storage device10aare mutually assembled in the second assembly position. In this case, the bottom cover60is tightly bound to the liquid storage device40, as shown inFIG.14. As described in Embodiment 1, the arrangement positions of the first snap-fit position31a,the second snap-fit position32a, and the matching snap-fit member14aare interchangeable, and similarly another fixed connection manner well-known by a person skilled in the art may be adopted. In this embodiment, the atomization assembly20ais connected to the liquid storage device10ain both the first assembly position and the second assembly position.

Continue to refer toFIG.13. The atomization assembly20aincludes a support23a, a third seal24a, an atomization core25a, and a base26a. Except that a second liquid guide hole231aof the support23ais not provided with a pressing member233, arrangement and assembly manners of the support23a, the third seal24a, the atomization core25a, and the base26ain Embodiment 2 are the same as those of the support23, the third seal24, the atomization core25, and the base26in Embodiment 1, and details are not described herein again.

To seal a liquid storage cavity12a, the atomization assembly20afurther includes a flexible sealing element22a, the flexible sealing element22ais arranged between the liquid storage cavity12aand the support23a, and has an outline matching the cross section of the inner contour of the liquid storage device10a, thereby sealing the liquid storage cavity12ato prevent liquid from leaking out from the liquid storage cavity12a. Specifically, in this embodiment, the flexible sealing element22ais nested on the top of the support23a, so that the support23aprovides rigid support for the flexible sealing element. In this case, the flexible sealing element23ablocks a conduction path between the second liquid guide hole231aof23aand the liquid storage cavity12a, so that the liquid in the liquid storage cavity12acannot flow towards the atomization assembly20a. In the first assembly position, the flexible sealing element22aseals the liquid storage cavity. In the second assembly position, the flexible sealing element22ais broken, the liquid in the liquid storage cavity12acan flow towards the atomization assembly20afor atomization. To cause the aerosol to circulate to the vent hole11aof the liquid storage device after being generated by the atomization assembly20a, the flexible sealing element22ais further provided with a ventilation hole221a, and the air conduit13ais connected to the ventilation hole221a.

Further, refer toFIG.15. To break the flexible sealing element22ain the second assembly position, a weak area222athat can be pressed and is easily broken is formed on the flexible sealing element22a, the weak area222ais defined by a groove formed on the flexible sealing element22a, and the groove may be set into various shapes by a person skilled in the art according to specific scenarios. In this embodiment, the shape of the groove is preferably set to a ring shape. Compared with other parts of the flexible sealing element22a, the weak area222ahas a very small thickness, and this thickness facilitates breaking of the weak area, and is, for example, approximately0.1mm. In the second assembly position, the weak area222acan be broken to conduct a circulation path between the second liquid guide hole231aof the support23aand the liquid storage cavity12a, so that the liquid in the liquid storage cavity12amay flow towards the atomization core25aof the atomization assembly20athrough the second liquid guide hole23la of the support23a.

Further, continue to refer toFIG.16with reference toFIG.14. To collaboratively enable the flexible sealing element22ato be broken in the second assembly position, a pressing member15aextending along the length direction of the liquid storage cavity12is collaboratively arranged in the liquid storage device10a, the pressing member15aextends into the liquid storage cavity12a, is used for releasing sealing of the sealing element22afor the liquid storage cavity12a, may be in a shape of a sheet or pole, and has a free end facing the open end of the liquid storage device10a, and the free end is configured as a pressing end151aused for pressing the seal. To cause the pressing member15ato have sufficient strength, to enable the pressing end151ato press and break the flexible sealing element22, the pressing member15ais at least partially connected to the air conduit13aof the liquid storage device10a.

With reference to the foregoing structural description, during production, the bottom cover30aequipped with the atomization assembly20amay be first pressed from the open end of the liquid storage device10a, until the first snap-fit position31aon the bottom cover30ais in snap-fit connection to the snap-fit member14aof the liquid storage device10a. In this case, the bottom cover30aand the liquid storage device10astill maintain a specific distance50abetween them and are not completely tightly bound to each other. In addition, the weak area222aof the flexible sealing element22aabuts against the pressing end151a, but the weak area222ahas not been broken, the liquid storage cavity12aand the second liquid guide hole231aof the support23aare still in an isolated or sealed state between each other, and this state is the pre-assembly state in the foregoing embodiment.

During use of the user, the user may further press the bottom cover30atoward the open end of the liquid storage device10a. In this case, the bottom cover30adrives the atomization assembly20ato further move toward the inside of the liquid storage device10a, until the second snap-fit position32aon the bottom cover30ais in snap-fit connection to the snap-fit member14aof the liquid storage device10a. In this process, the weak area222aof the sealing element22ais further pressed by the pressing end151a, so that the weak area222ais broken under pressing of the pressing end151a. Therefore, the liquid storage cavity12aand the second liquid guide hole231aof the support23aare conducted between each other, and the liquid matrix may flow from the liquid storage cavity12atowards the atomization assembly20afor atomization.

It may be understood that because the sealing element22ain this embodiment is made of a flexible material, for example, may be made of a silicone material in this embodiment, the pressing end151amay be preferably configured into a spike shape. When the sealing element22afurther moves from the first assembly position to the second assembly position with the bottom cover30a, the pressing end151ain the spike shape pierces the weak area222aof the flexible sealing element22aat a point. Because the flexible sealing element22ahas a specific elastic force, the weak area222ashrinks to the vicinity quickly with the piercing point as the center under the elastic force, thereby expanding the breaking range. In this manner, the weak area222adoes not fall into the atomization assembly20to form fixed residues because of being broken under pressing of the pressing end151a.

In some embodiments, the sealing element22amay alternatively be made of a rigid plastic material. In this case, the weak area222ais also made of a rigid plastic material. When the sealing element22afurther moves from the first assembly position to the second assembly position with the bottom cover30a, the pressing end151apresses the weak area222a. Because the weak area222ais made of a rigid plastic material, the weak area222ais under a pressing force of the pressing end151a, and at least one part of the weak area222ais broken. Therefore, the liquid storage cavity12aand the second liquid guide hole231aof the support23acan also be conducted between each other.

The present invention further provides an electronic atomization apparatus. The electronic atomization apparatus includes the foregoing atomization device and a power supply mechanism (not shown), and the atomization device is detachably connected to or fixedly connected to the power supply mechanism. The power supply mechanism includes a cell (not shown), a control board (not shown), and a fixed base (not shown). The control board is fixed onto the fixed base, the fixed base is provided with a first elastic sheet (not shown) and a second elastic sheet (not shown), and the first elastic sheet and the second elastic sheet are electrically connected to the control board, and are electrically connected to the cell through the control board. When the atomization device is detachably connected to the power supply mechanism, the power supply mechanism is provided with an accommodating cavity (not shown) matching an overall shape of the atomization device. When the atomization device is accommodated in the accommodating cavity, a first electrode contact22aand a second electrode contact22bof the atomization device abut against the first elastic sheet and the second elastic sheet of the power supply mechanism respectively, to help the power supply mechanism supply power to the atomization device.
