The lower sealing ring abuts against the first partition member to seal the first through hole. And/or, the side of the first partition member towards the cover plate is provided with an upper sealing ring. The upper sealing ring abuts against the cover plate to seal the first through hole.

As shown in FIG. 1, an embodiment of the present disclosure provides an atomizer. The atomizer includes a housing 1, a first partition member 21, an atomization assembly 3, a movable member 4, and a driving member 51. The housing 1 is at least internally provided with a storage cavity 11 for storing an aerosol generating substrate and an atomization cavity 12. The first partition member 21 is arranged between the storage cavity 11 and the atomization cavity 12, to partition the storage cavity 11 from the atomization cavity 12. The first partition member 21 is provided with a first through hole 211 for enabling the storage cavity 11 to be in communication with the atomization cavity 12. The atomization assembly 3 is arranged in the housing 1 and at least partially located in the atomization cavity 12, to process the aerosol generating substrate entering the atomization cavity 12. The movable member 4 is movably connected to the first partition member 21, to move relative the first partition member 21. The driving member 51 is connected to the movable member 4. The driving member 51 is used for driving, when a power supply is turned on or turned off, the movable member 4 to move to seal or open the first through hole 211.

Specifically, the storage cavity 11 and the atomization cavity 12 are two independent cavities formed in the housing 1. The storage cavity 11 is completely sealed when the storage cavity is not in communication with the atomization cavity 12. The aerosol generating substrate is mainly stored in the storage cavity 11. The atomization cavity 12 is in communication with the atomization assembly 3. The atomization assembly 3 is generally provided with an atomization hole having a tiny diameter. When a user performs vaping, under the action of a vaping force, the aerosol generating substrate in the atomization cavity 12 is dispersed into tiny liquid particles when vaped into the atomization assembly 3 through the atomization hole having the tiny diameter, such that the aerosol generating substrate is atomized into aerosols. Thus, the atomization cavity 12 may be in communication with the outside through the atomization assembly 3. To reduce leakage of the aerosol generating substrate, generally, only a small part of the aerosol generating substrate that needs to be atomized by the atomization assembly 3 and allows a user to vape is stored in the atomization cavity 12. In this way, the aerosol generating substrate is atomized and output soon after entering the atomization cavity 12, and the atomization assembly 3 is not soaked in the aerosol generating substrate for a long time, such that influence of the atomization assembly 3 on a mouthfeel of the aerosols is reduced. Optionally, the storage cavity 11 may be directly filled with the aerosol generating substrate, and additional liquid storage cotton does not need to be arranged to absorb and store the aerosol generating substrate, such that a structure and a liquid injection operation can be simplified. Meanwhile, the housing 1 may be made of a transparent material. In this way, a remaining amount of the aerosol generating substrate stored in the storage cavity 11 is visible, which can help a user learn the current remaining amount of the aerosol generating substrate in the atomizer, so as to facilitate supplementation of the aerosol generating substrate or replacement of the atomizer in time.

Specifically, the first partition member 21 partitions the storage cavity 11 from the atomization cavity 12. When the first through hole 211 provided on the first partition member 21 is closed, the storage cavity 11 is completely partitioned from the atomization cavity 12. The first through hole 211 is opened only during use, and part of the aerosol generating substrate in the storage cavity 11 is transferred to the atomization cavity 12. In this way, after the part of the aerosol generating substrate is atomized by the atomization assembly 3, the aerosols are formed to be vaped by a user. In this way, leakage of the aerosol generating substrate in the storage cavity 11 from the atomization cavity 12 can be avoided. It may be understood that, to ensure sealing performance, the first partition member 21 generally includes a sealing layer made of a flexible material such as silica gel. When the movable member 4 seals the first through hole 211, the movable member 4 may abut against the sealing layer on the first partition member 21 and press the sealing layer to a certain extent, such that the sealing layer is deformed and blocks a gap between the movable member 4 and the first partition member 21. In this way, desirable sealing can be achieved. The sealing layer may be part of the first partition member 21, or may be an independent part, as long as a sealing effect can be achieved.

Specifically, the movable member 4 is movably connected to the first partition member 21. The driving member 51 is connected to the movable member 4. When the driving member 51 is powered on, the driving member 51 drives the movable member 4 to move to seal or open the first through hole 211. When a user performs vaping, the driving member 51 is powered on and drives the movable member 4 to move to open the first through hole 211, such that the aerosol generating substrate in the storage cavity 11 enters the atomization cavity 12, and is atomized by the atomization assembly 3. When a user stops vaping, the driving member 51 is powered off and stops driving the movable member 4, such that the movable member 4 may return to a position at which the first through hole 211 is sealed, so as to seal the first through hole 211. In this way, a situation that the aerosol generating substrate in the storage cavity 11 enters the atomization cavity 12 and causes leakage is prevented.

Optionally, the atomizer may be further internally provided with components such as a detection member for detecting a change in air pressure in the atomization assembly 3. Whether a user performs vaping is determined by detecting the change in air pressure, and a power-on circuit of the driving member 51 is controlled to be connected or disconnected. During use, manual control is not needed, and convenient use is achieved. Optionally, a power supply form for supplying power to the driving member 51 is not limited, which may be a built-in battery of the atomizer, a battery of an electronic atomization device used when the atomizer is applied to the electronic atomization device, or an external power supply, as long as power can be supplied to the driving member 51 so as to achieve a driving function of the driving member.

It should be noted that the driving member 51 needs to be powered on to perform a driving action. A specific form of the driving member 51 may be a structure generating mechanical motion such as an electric cylinder, and the movable member 4 is driven to move synchronously through generation of the mechanical motion. In addition, the driving member 51 may be a component that generates heat and becomes deformed when powered on, and drives the movable member 4 to move through deformation. For example, the driving member 51 may be a component made of a memory alloy material. When a temperature of the driving member 51 rises to a critical value, the driving member may be deformed, and the generated deformation may drive the movable member 4 to move. After the temperature of the driving member 51 drops due to power failure, a shape of the driving member 51 may be restored to a state without deformation, and the movable member 4 may be restored.

It may be understood that, the driving member 51 may perform driving in other modes. For example, when the driving member 51 is a component made of a memory alloy material, the driving member 51 may be deformed only through heating. A heating mode is not limited to a mode of directly turning on a power supply. However, to ensure use experience, when a user performs vaping, the driving member 51 needs to respond and complete driving in time, to drive the movable member 4 to move as soon as possible and open the first through hole 211, where an opening amplitude should not be excessive. Thus, a driving distance, driving time, etc. of the driving member 51 need to be accurately controlled. However, when the driving member 51 performs driving in a mode of turning on the power supply, parameters such as power-on time and electric power may be controlled, such that a driving state of the driving member 51 is better controlled, to ensure that the driving member 51 responds quickly and timely with an accurate driving distance and a moderate driving amplitude. Meanwhile, it may be ensured that the driving member 51 is within a safe power and temperature range, a problem of reduced service life or even damage caused by overheating of the driving member 51 is avoided, and safety is ensured.

The atomizer provided by an embodiment of the present disclosure includes a housing 1, a first partition member 21, an atomization assembly 3, a movable member 4, and a driving member 51. The housing 1 is internally provided with the storage cavity 11 and the atomization cavity 12. The first partition member 21 partitions the storage cavity 11 from the atomization cavity 12. The storage cavity 11 may be directly filled with the aerosol generating substrate, and the additional liquid storage cotton does not need to be arranged, such that the structure and the liquid injection operation can be simplified. When the housing 1 is made of a transparent material, the remaining amount of the aerosol generating substrate in the storage cavity 11 is visible, which can help a user learn the current remaining amount of the aerosol generating substrate in the atomizer. The first partition member 21 is provided with the first through hole 211 enabling the storage cavity 11 to be in communication with the atomization cavity 12. The movable member 4 is movably connected to the first partition member 21. The driving member 51 drives the movable member 4 to move relative to the first partition member 21 to seal or open the first through hole 211. The driving member 51 may be powered on only when the atomizer is used, and the first through hole 211 may be opened, such that the aerosol generating substrate stored in the storage cavity 11 enters the atomization cavity 12 to be atomized. The first through hole 211 may be sealed when the atomizer is not used, and the storage cavity 11 may be completely partitioned from the atomization cavity 12. Thus, the aerosol generating substrate stored in the storage cavity 11 can be prevented from leaking. Waste caused by leakage of the aerosol generating substrate is reduced while the liquid storage cotton is not used, and a use rate of the aerosol generating substrate is improved. In addition, after entering the atomization cavity 12, the aerosol generating substrate is rapidly atomized and output. The atomization assembly 3 is not immersed in the aerosol generating substrate for a long time, thus desirably reducing influence of the atomization assembly 3 on a mouthfeel of the aerosols. Meanwhile, the driving member 51 is controlled in a power-on manner, such that a driving state of the driving member 51 can be better controlled, and safety of the driving member 51 is ensured.

In some embodiments, as shown in FIG. 1, the housing 1 is further internally provided with a mounting cavity 13 for accommodating at least the driving member 51. A second partition member 22 for partitioning the mounting cavity 13 from the atomization cavity 12 is arranged between the mounting cavity 13 and the atomization cavity 12. The second partition member 22 is provided with a second through hole 221 for allowing the movable member 4 to penetrate to be connected to the driving member 51. The second partition member 22 is hermetically connected to the movable member 4.

Specifically, the driving member 51 is arranged in the mounting cavity 13, and the mounting cavity 13 is partitioned from the atomization cavity 12 through the second partition member 22. The movable member 4 penetrates the second partition member 22 through the second through hole 221 provided on the second partition member 22. Meanwhile, in a moving process of the movable member 4 relative to the first partition member 21, the second partition member 22 is hermetically connected to the movable member 4 all the time. In this way, an adverse effect such as corrosion caused by contact between the aerosol generating substrate in the atomization cavity 12 and the driving member 51 can be prevented, and reliability of the driving member 51 can be ensured. To achieve hermetic connection between the second partition member 22 and the movable member 4 all the time, a flexible deformable component such as a silica gel member may be set as the second partition member 22, and the second partition member 22 may be in interference fit with the movable member 4, so as to ensure that the second partition member 22 always abuts against the movable member 4. In this way, when the movable member 4 moves, the second partition member 22 may be synchronously deformed to compensate for a position offset of the movable member 4. As long as a joint between the second partition member 22 and the movable member 4 is relatively static, sealed connection can always be maintained. A problem that the aerosol generating substrate in the atomization cavity 12 leaks to the mounting cavity 13 and makes contact with the driving member 51 due to a gap during movement of the movable member 4 is avoided.

In some embodiments, as shown in FIG. 1, the movable member 4 includes a piston rod 41 and a cover plate 42. The piston rod 41 at least penetrates the first through hole 211 and the second through hole 221 and is movable relative to the first partition member 21. The cover plate 42 is arranged on the piston rod 41. The cover plate 42 is used for moving synchronously with the piston rod 41, to seal or open the first through hole 211. The second partition member 22 is hermetically connected to the piston rod 41. The driving member 51 is connected to the end of the piston rod 41 in the mounting cavity 13, to drive the piston rod 41 and the cover plate 42 to move.

Optionally, as shown in FIG. 1, the piston rod 41 and the cover plate 42 may be integrally formed to form different parts of the movable member 4. In addition, the piston rod 41 and the cover plate 42 may be separately arranged and connected in an assembly manner. The piston rod 41 and the cover plate 42 may be detachably or undetachably connected. Optionally, as shown in FIG. 1, the cover plate 42 may be located at the side of the first partition member 21 towards the storage cavity 11, that is, above the first partition member 21 in FIG. 1. In this way, when the cover plate 42 moves upward, the first through hole 211 may be opened. Otherwise, the first through hole 211 is sealed. In addition, it may be understood that, the cover plate 42 may be located at the side of the first partition member 21 towards the atomization cavity 12, that is, below the first partition member 21. In this way, when the cover plate 42 moves downward, the first through hole 211 may be opened. Otherwise, the first through hole 211 is sealed.

In some embodiments, as shown in FIG. 1, the atomizer further includes a limiting support 6 connected to the first partition member 21. The limiting support 6 is provided with a first guiding hole 61. The end of the piston rod 41 farther from the mounting cavity 13 penetrates the first guiding hole 61, and is provided with a limiting part 411. The limiting part 411 is used for abutting against the limiting support 6, to limit a position at which the cover plate 42 seals the first through hole 211.

In this way, the piston rod 41 penetrates the first guiding hole 61, and the first guiding hole 61 guides movement of the piston rod 41 at an end of the piston rod 41, such that stability of the movement of the piston rod 41 can be improved. Meanwhile, the limiting part 411 abuts against the limiting support 6, to limit a position at which the cover plate 42 seals the first through hole 211. In this way, when the driving member 51 is powered off, the cover plate 42 may return to an appropriate position to seal the first through hole 211, thus preventing a problem of excessive pressing on the first partition member 21.

In some embodiments, as shown in FIG. 2, the side of the cover plate 42 towards the first partition member 21 is provided with a lower sealing ring 421. The lower sealing ring 421 abuts against the first partition member 21 to seal the first through hole 211. Specifically, the lower sealing ring 421 is an annular protrusion structure arranged at the side of the cover plate 42 towards the first partition member 21. The lower sealing ring 421 abuts against the first partition member 21, and specifically abuts against the sealing layer made of a flexible material such as silica gel on the first partition member 21. In this way, the lower sealing ring 421 may press the sealing layer to make the sealing layer deformed. Meanwhile, the sealing layer has a tendency to spring back, and can abut against the lower sealing ring 421 all the time, thus achieving desirable sealing. In this way, the cover plate 42 abuts against the first partition member 21 through the relatively protruding lower sealing ring 421, which further improves reliability of contact and sealing. In this way, a poor sealing effect caused by poor contact between the cover plate 42 and the first partition member 21 when a surface of the cover plate is uneven can be avoided.

In order to achieve the same effect, it may be understood that the side of the first partition member 21 towards the cover plate 42 may be provided with an upper sealing ring, and the upper sealing ring abuts against the cover plate 42, to seal the first through hole 211. In addition, the lower sealing ring 421 and the upper sealing ring may be arranged simultaneously, or a plurality of lower sealing rings and a plurality of upper sealing rings may be arranged, so as to further improve fitness and sealing.

In some embodiments, as shown in FIG. 1, the atomizer further includes a first conducting member 7 and a second conducting member 8. The first conducting member 7 is arranged in the mounting cavity 13 and connected to the end of the piston rod 41 in the mounting cavity 13. The first conducting member 7 is provided with a guiding rod 71 in a direction away from the piston rod 41 in an extending manner. The second conducting member 8 is arranged in the mounting cavity 13. The second conducting member 8 is provided with a second guiding hole 81 for allowing the guiding rod 71 to penetrate, to limit moving directions of the guiding rod 71 and the first conducting member 7. The driving member 51 is arranged between the first conducting member 7 and the second conducting member 8, to drive the first conducting member 7 to drive the piston rod 41 to move when the driving member is powered on. Specifically, the first conducting member 7 and the second conducting member 8 are conductive components connected to the power supply, and generally, may be connected to positive and negative electrodes of the power supply respectively, such that the driving member 51 and the power supply form a power-on circuit. In this way, the first conducting member 7 is connected to the piston rod 41, the first conducting member 7 is provided with the guiding rod 71 in an extending manner, and the guiding rod 71 penetrates the second guiding hole 81 provided on the second conducting member 8. In this way, in addition to a conducting function, the first conducting member 7 and the second conducting member 8 may serve as guiding components, and have a guiding function and a limiting function for movement of the piston rod 41. Thus, the design is flexible and delicate, and stability of movement of the piston rod 41 is further improved.

In some embodiments, as shown in FIG. 3, the end of the piston rod 41 for being connected to the first conducting member 7 is provided with an insertion hole 412. The end of the first conducting member 7 towards the piston rod 41 is inserted into the insertion hole 412. Or, the end of the first conducting member 7 for being connected to the piston rod 41 is provided with an insertion hole 412. The end of the piston rod 41 in the mounting cavity 13 is inserted into the insertion hole 412. The circle center of the insertion hole 412 is located on the axis of the guiding rod 71. In this way, the first conducting member 7 is inserted into the piston rod 41, and the insertion hole 412 and the guiding rod 71 are coaxially arranged. In this way, the end of the first conducting member 7 is limited and guided by the second guiding hole 81 (shown in FIG. 1) through the guiding rod 71, and the other end of the first conducting member is inserted into the piston rod 41 through the insertion hole 412 so as to be limited and guided. Thus, the first conducting member 7 drives the piston rod 41 to move more stably. It may be understood that, the insertion hole 412 may be provided on the piston rod 41, or the first conducting member 7, as long as the first conducting member 7 is inserted into the piston rod 41.

In some embodiments, the driving member 51 is an elastic member that is powered on to generate a driving force. Specifically, the elastic member is used for generating, when the power supply is turned on, an elastic force acting on the movable member 4, to drive the movable member 4 to move and open the first through hole 211. The driving member 51 may apply an elastic force to the first conducting member 7, to drive the first conducting member 7 to move the piston rod 41, such that the cover plate 42 is driven to open the first through hole 211.

Specifically, the driving member 51 may be configured as a component such as a spring made of a memory alloy material. When the power supply is turned off, deformation generated when the driving member 51 is pressed by an upper component is plastic deformation. In this case, an elastic force is not generated, and the first through hole 211 is in a sealed state. However, when the power supply is turned on, a temperature of the driving member 51 may quickly rise to a critical temperature and restore to a state before plastic deformation. In this case, the driving member 51 springs back by counteracting a pressing force of an upper component. Accordingly, the driving member 51 may apply an elastic force to a component such as the first conducting member 7, to finally drive the movable member 4 to move and open the first through hole 211. In this process, through proper design, the temperature of the driving member 51 may be controlled to be kept in a state slightly higher than a critical temperature when the driving member is powered on. In this way, when the power supply is turned off again, the temperature of the driving member 51 may quickly drop to the critical temperature, and application of the elastic force is stopped in time.

In this way, an elastic member that is powered on to generate a driving force may be set as the driving member 51, and is specifically an elastic member made of a memory alloy material. In this way, the driving member 51 has elasticity only when the power supply is turned on, to achieve a driving function, and may stop driving in time when the power supply is turned off, such that timely response and convenient control are implemented.

In some embodiments, as shown in FIG. 1, the atomizer further includes a restoring member 52. The restoring member 52 is connected to the movable member 4. The restoring member 52 is used for driving, when the driving member 51 is powered off, the movable member 4 to be restored to seal the first through hole 211. Specifically, the restoring member 52 may be arranged between the cover plate 42 and the limiting support 6, and applies an acting force to the cover plate 42 to restore the cover plate, so as to seal the first through hole 211. Optionally, the restoring member 52 may be a component having elasticity such as a bias spring or an elastic sheet, and the movable member 4 is restored by applying an elastic force. In addition, the restoring member 52 may be a weight member for increasing a weight. When the driving member 51 is powered off, the cover plate 42 is pushed to be restored by gravity of the restoring member. In this way, the restoring member 52 is used for driving the movable member 4 to be restored when the driving member 51 is powered off, to seal the first through hole 211, such that a restoring speed of the movable member 4 may be increased, and the first through hole 211 is sealed in time to prevent leakage of the aerosol generating substrate.

As shown in FIG. 1, an embodiment of the present disclosure further provides an electronic atomization device. The electronic atomization device includes a battery 9 and the atomizer. The battery 9 is at least electrically connected to a driving member 51, to supply power to the driving member 51. It may be understood that the battery 9 may be arranged in the housing 1 of the atomizer, or outside the atomizer. In addition to supplying power to the driving member 51, the battery 9 may supply power to other electronic elements of the electronic atomization device, and for example, may supply power to a heating wire on the atomization assembly 3, or may supply power to a component such as a detection member for detecting a change in air pressure in the atomization assembly 3.

The electronic atomization device provided by the embodiment of the present disclosure uses the atomize. However, the atomizer may reduce waste caused by leakage of the aerosol generating substrate and improve a use rate of the aerosol generating substrate. Thus, when the atomizer is applied to the electronic atomization device, leakage of the aerosol generating substrate in the electronic atomization device is reduced, a use rate of the aerosol generating substrate is improved, and use time of the electronic atomization device is prolonged. In addition, when the housing 1 of the atomizer is made of a transparent material, the storage amount of the internal aerosol generating substrate may further be intuitively observed, and use experience of the electronic atomization device is improved.

While the invention has been illustrated and described in detail in the drawings and foregoing description, such illustration and description are to be considered illustrative or exemplary and not restrictive. It will be understood that changes and modifications may be made by those of ordinary skill within the scope of the following claims. In particular, the present invention covers further embodiments with any combination of features from different embodiments described above and below. Additionally, statements made herein characterizing the invention refer to an embodiment of the invention and not necessarily all embodiments.

The terms used in the claims should be construed to have the broadest reasonable interpretation consistent with the foregoing description. For example, the use of the article “a” or “the” in introducing an element should not be interpreted as being exclusive of a plurality of elements. Likewise, the recitation of “or” should be interpreted as being inclusive, such that the recitation of “A or B” is not exclusive of “A and B,” unless it is clear from the context or the foregoing description that only one of A and B is intended. Further, the recitation of “at least one of A, B and C” should be interpreted as one or more of a group of elements consisting of A, B and C, and should not be interpreted as requiring at least one of each of the listed elements A, B and C, regardless of whether A, B and C are related as categories or otherwise. Moreover, the recitation of “A, B and/or C” or “at least one of A, B or C” should be interpreted as including any singular entity from the listed elements, e.g., A, any subset from the listed elements, e.g., A and B, or the entire list of elements A, B and C.
