[0001] The utility model relates to the technical field of atomization, and particularly relates to an atomizer and an electronic atomization device. Background Art

[0034] Such as Figure 1As shown in the figure, an embodiment of the present utility model provides an atomizer, which includes a housing 1, a first partition member 21, an atomization assembly 3, a movable member 4, and a driving member 51. Inside the housing 1, there are at least a storage cavity 11 for storing an aerosol generation matrix and an atomization cavity 12. The first partition member 21 is disposed between the storage cavity 11 and the atomization cavity 12 to separate the storage cavity 11 and the atomization cavity 12. The first partition member 21 is provided with a first through hole 211 for communicating the storage cavity 11 and the atomization cavity 12. The atomization assembly 3 is disposed inside the housing 1 and at least partially located in the atomization cavity 12 to process the aerosol generation matrix entering the atomization cavity 12. The movable member 4 is movably connected to the first partition member 21 to be able to move relative to the first partition member 21. The driving member 51 is connected to the movable member 4. The driving member 51 is used to drive the movable member 4 to move when the power is turned on or off to seal or open the first through hole 211.

[0035] Specifically, the storage cavity 11 and the atomization cavity 12 are two independent cavities formed inside the housing 1. Among them, the storage cavity 11 is completely closed when not communicating with the atomization cavity 12. The aerosol generation matrix is mainly stored in the storage cavity 11, while the atomization cavity 12 is connected to the atomization assembly 3. The atomization assembly 3 is usually provided with atomization holes with small apertures. When the user sucks, under the action of the suction force, the aerosol generation matrix in the atomization cavity 12 passes through the atomization holes with small apertures and is dispersed into tiny droplets during the process of being sucked into the atomization assembly 3, thereby atomizing the aerosol generation matrix into aerosol. Therefore, the atomization cavity 12 can communicate with the outside through the atomization assembly 3. In order to reduce the leakage of the aerosol generation matrix, only a small part of the aerosol generation matrix that needs to be atomized by the atomization assembly 3 and sucked by the user is usually stored in the atomization cavity 12. In this way, the aerosol generation matrix is quickly atomized and output after entering the atomization cavity 12, and the atomization assembly 3 is not immersed in the aerosol generation matrix for a long time, thereby preferably reducing the influence of the atomization assembly 3 on the taste of the aerosol. Optionally, the aerosol generation matrix can be directly poured into the storage cavity 11 without additionally providing a liquid storage cotton to absorb and store the aerosol generation matrix, which can simplify the structure and the liquid injection operation. At the same time, the housing 1 can also be made of a transparent material. In this way, the remaining amount of the aerosol generation matrix stored in the storage cavity 11 is visible, which can facilitate the user to know the remaining amount of the aerosol generation matrix in the current atomizer, so as to timely supplement the aerosol generation matrix or replace the atomizer.

[0036] Specifically, the first partition 21 separates the storage chamber 11 and the atomization chamber 12 from each other. When the first through hole 211 provided on the first partition 21 is closed, the storage chamber 11 and the atomization chamber 12 are completely isolated. The first through hole 211 is opened only when it is needed, and a part of the aerosol generating matrix in the storage chamber 11 is transferred to the atomization chamber 12, so that this part of the aerosol generating matrix is ​​atomized by the atomization component 3 to form an aerosol for the user to inhale. In this way, the problem of the aerosol generating matrix in the storage chamber 11 leaking through the atomization chamber 12 can be avoided. It can be understood that in order to ensure the sealing performance, the first partition 21 usually includes a sealing layer made of a flexible material such as silica gel. When the movable part 4 seals the first through hole 211, the movable part 4 can abut against the sealing layer on the first partition 21 and cause a certain amount of extrusion, so that the sealing layer is deformed and blocks the gap between the movable part 4 and the first partition 21, so that a good seal can be formed. The sealing layer may be a part of the first separator 21 or an independent component, as long as the sealing effect can be achieved.

[0037] Specifically, the movable member 4 is movably connected to the first partition 21, and the driving member 51 is connected to the movable member 4. When the driving member 51 is powered on, the movable member 4 is driven by the driving member 51 to move to seal or open the first through hole 211. When the user takes a puff, the driving member 51 is powered on to drive the movable member 4 to move to open the first through hole 211, so that the aerosol-generating substrate in the storage chamber 11 enters the atomizing chamber 12 and is atomized by the atomizing assembly 3. When the user stops taking a puff, the driving member 51 disconnects the power supply and stops driving the movable member 4, so that the movable member 4 can return to the position of closing the first through hole 211, and close the first through hole 211 to prevent the aerosol-generating substrate in the storage chamber 11 from entering the atomizing chamber 12 and causing leakage. Optionally, the atomizer may be provided with a detection member or other components for detecting the change of air pressure in the atomizer assembly 3, and the detection of the change of air pressure is used to determine whether the user is inhaling, and the power circuit of the driving member 51 is controlled to be connected or disconnected, so that manual control is not required during use, and it is convenient to use. Optionally, the power supply for the driving member 51 is not limited, and can be a battery in the atomizer, or a battery of the electronic atomization device when the atomizer is applied to the electronic atomization device, or an external power supply, etc., as long as it can power the driving member 51 to achieve the driving function.

[0038] It should be noted that the driving member 51 needs to be powered on to drive. The form of the driving member 51 can specifically be a structure that generates mechanical motion, such as an electric cylinder, which drives the movable member 4 to move synchronously by generating mechanical motion. In addition, the driving member 51 can also be a component that generates heat and deforms when powered on, and drives the movable member 4 to move through its own deformation. For example, the driving member 51 can be a component made of shape memory alloy material. When the temperature of the driving member 51 rises to the critical value, it can generate deformation, and the generated deformation can play a role in driving the movable member 4 to move. After the power is cut off and the temperature of the driving member 51 drops, the shape of the driving member 51 returns to the state without deformation, and the movable member 4 can be reset.

[0039] It can be understood that the driving member 51 can also be driven in other ways. For example, when the driving member 51 is a component made of shape memory alloy material, it only needs to be able to heat the driving member 51 to make it generate deformation, and the heating method is not limited to directly connecting to the power supply. However, to ensure the user experience, when the user sucks, the driving member 51 needs to respond in a timely manner and complete the driving, quickly drive the movable member 4 to move and open the first through hole 211, and the opening amplitude should not be too large. Therefore, it is necessary to precisely control the driving distance, driving time, etc. of the driving member 51. By using the method of connecting to the power supply to drive the driving member 51, parameters such as the power-on time and electric power can be controlled, so as to better control the driving state of the driving member 51, ensure that the driving member 51 responds quickly and timely, the driving distance is accurate, and the driving amplitude is appropriate. At the same time, it can also ensure that the driving member 51 is within a safe power and temperature range, avoiding problems such as reducing the service life or even damage due to overheating of the driving member 51, and ensuring safety.

[0040] The atomizer provided by the embodiment of the present utility model includes a housing 1, a first partition member 21, an atomization assembly 3, a movable member 4, and a driving member 51. A storage cavity 11 and an atomization cavity 12 are formed inside the housing 1. The first partition member 21 separates the storage cavity 11 and the atomization cavity 12. The aerosol-generating matrix can be directly filled into the storage cavity 11 without additionally arranging a liquid storage cotton, which simplifies the structure and the liquid filling operation. When the housing 1 is made of a transparent material, the remaining amount of the aerosol-generating matrix in the storage cavity 11 is visible, which is convenient for the user to know the remaining amount of the aerosol-generating matrix in the atomizer at present. A first through hole 211 communicating the storage cavity 11 and the atomization cavity 12 is formed on the first partition member 21. By movably connecting the movable member 4 with 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 can be powered on only when the atomizer is in use to open the first through hole 211 so that the aerosol-generating matrix stored in the storage cavity 11 enters the atomization cavity 12 for atomization treatment. When the atomizer is not in use, the first through hole 211 can be closed to completely isolate the storage cavity 11 and the atomization cavity 12, which can prevent the aerosol-generating matrix stored in the storage cavity 11 from leaking. Thus, without using a liquid storage cotton, the waste caused by the leakage of the aerosol-generating matrix is reduced, and the utilization rate of the aerosol-generating matrix is improved. Moreover, after the aerosol-generating matrix enters the atomization cavity 12, it is quickly atomized and output, and the atomization assembly 3 is not soaked in the aerosol-generating matrix for a long time, which preferably reduces the influence of the atomization assembly 3 on the taste of the aerosol. At the same time, by controlling the driving member 51 in an electrified manner, the driving state of the driving member 51 can be better controlled, and the safety of the driving member 51 is ensured.

[0041] In some embodiments, as Figure 1 shown, an installation cavity 13 for at least accommodating the driving member 51 is further formed inside the housing 1. A second partition member 22 for separating the installation cavity 13 and the atomization cavity 12 is arranged between the installation cavity 13 and the atomization cavity 12. A second through hole 221 for allowing the movable member 4 to pass through to connect the driving member 51 is formed on the second partition member 22. Among them, the second partition member 22 is hermetically connected with the movable member 4.

[0042] Specifically, the driving member 51 is disposed in the installation cavity 13, and the installation cavity 13 is separated from the atomization cavity 12 by the second partition member 22. Among them, the movable member 4 passes through the second partition member 22 through the second through hole 221 formed in the second partition member 22. At the same time, during the process of the movable member 4 moving relative to the first partition member 21, the second partition member 22 is always hermetically connected to the movable member 4, so as to prevent the aerosol generating matrix in the atomization cavity 12 from contacting the driving member 51 and causing adverse effects such as corrosion, and ensure the reliability of the driving member 51. To achieve the hermetic connection between the second partition member 22 and the movable member 4 all the time, the second partition member 22 can be set as a deformable flexible component such as a silica gel member, and the second partition member 22 and the movable member 4 are set to have an interference fit to ensure that the second partition member 22 and the movable member 4 are always in close contact. In this way, when the movable member 4 moves, the second partition member 22 can deform synchronously to compensate for the position offset of the movable member 4. As long as the connection between the second partition member 22 and the movable member 4 is relatively stationary, the hermetic connection can be maintained all the time, avoiding the problem that the aerosol generating matrix in the atomization cavity 12 leaks into the installation cavity 13 to contact the driving member 51 during the movement of the movable member 4.

[0043] In some embodiments, as Figure 1 shown, the movable member 4 includes a piston rod 41 and a cover plate 42. The piston rod 41 is at least disposed in the first through hole 211 and the second through hole 221, and can move relative to the first partition member 21. The cover plate 42 is disposed on the piston rod 41, and the cover plate 42 is used to move synchronously with the piston rod 41 to seal or open the first through hole 211. Among them, the second partition member 22 is hermetically connected to the piston rod 41, and the driving member 51 is connected to one end of the piston rod 41 located in the installation cavity 13 to drive the piston rod 41 and the cover plate 42 to move.

[0044] Optionally, as Figure 1 shown, the piston rod 41 and the cover plate 42 can be integrally formed to form different parts of the movable member 4; in addition, the piston rod 41 and the cover plate 42 can also be separately provided and connected by an assembly method, and the connection between the piston rod 41 and the cover plate 42 can be detachable or non-detachable. Optionally, as Figure 1 shown, the cover plate 42 can be located on the side of the first partition member 21 facing the storage cavity 11, that is, Figure 1 above the first partition member 21 in

[0045] In some embodiments, as Figure 1As shown, the atomizer further includes a limit bracket 6 connected to the first partition 21, and a first guiding hole 61 is formed in the limit bracket 6. One end of the piston rod 41 away from the installation cavity 13 passes through the first guiding hole 61, and a limiting portion 411 is provided. The limiting portion 411 is used to abut against the limit bracket 6 to define the position where the cover plate 42 seals the first through hole 211.

[0046] In the above design, by passing the piston rod 41 through the first guiding hole 61, the first guiding hole 61 guides the movement of the piston rod 41 at the end of the piston rod 41, which can improve the stability of the movement of the piston rod 41. At the same time, by using the limiting portion 411 to abut against the limit bracket 6 to define the position where 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 can return to an appropriate position to seal the first through hole 211, preventing the problem of excessive extrusion of the first partition 21.

[0047] In some embodiments, as Figure 2 As shown, a lower sealing ring 421 is provided on the side of the cover plate 42 facing the first partition 21. The lower sealing ring 421 abuts against the first partition 21 to seal the first through hole 211. Specifically, the lower sealing ring 421 refers to an annular protrusion structure provided on the side of the cover plate 42 facing the first partition 21. The lower sealing ring 421 abuts against the first partition 21, specifically referring to abutting against a sealing layer made of a flexible material such as silica gel on the first partition 21. In this way, the lower sealing ring 421 can squeeze the sealing layer to make the sealing layer sink and deform. At the same time, the sealing layer has a tendency to rebound and can always keep in contact with the lower sealing ring 421, thereby forming a good seal. In the above design, the cover plate 42 abuts against the first partition 21 through the relatively protruding lower sealing ring 421, further improving the reliability of the fitting seal, and can avoid the problem of poor sealing effect caused by poor fitting degree between the cover plate 42 and the first partition 21 when the surface of the cover plate 42 is uneven.

[0048] To achieve the same effect, it can be understood that an upper sealing ring (not shown in the figure) can also be provided on the side of the first partition 21 facing the cover plate 42. The upper sealing ring abuts against the cover plate 42 to seal the first through hole 211. Moreover, the above-mentioned lower sealing ring 421 and upper sealing ring can also be provided simultaneously, and multiple ones can also be provided separately to further improve the fitting degree and improve the sealing performance.

[0049] In some embodiments, as Figure 1As shown, the atomizer further includes a first conductive member 7 and a second conductive member 8. The first conductive member 7 is disposed in the installation cavity 13 and is connected to one end of the piston rod 41 located in the installation cavity 13. The first conductive member 7 is provided with a guide rod 71 extending in a direction away from the piston rod 41. The second conductive member 8 is disposed in the installation cavity 13. A second guide hole 81 for the guide rod 71 to pass through is formed in the second conductive member 8 to define the moving direction of the guide rod 71 and the first conductive member 7. Among them, the driving member 51 is disposed between the first conductive member 7 and the second conductive member 8 so as to be able to drive the first conductive member 7 to drive the piston rod 41 to move when the power is connected. Specifically, the first conductive member 7 and the second conductive member 8 are conductive components connected to the power supply, and usually can be respectively connected to the positive and negative poles of the power supply so that the driving member 51 forms a powered-on circuit with the power supply. In the above design, by connecting the first conductive member 7 to the piston rod 41, and the first conductive member 7 is extended to provide the guide rod 71, and the guide rod 71 passes through the second guide hole 81 formed in the second conductive member 8. In this way, in addition to the conductive function, the first conductive member 7 and the second conductive member 8 can also act as guiding components, having a guiding and limiting effect on the movement of the piston rod 41. The design is flexible and ingenious, and further improves the stability of the movement of the piston rod 41.

[0050] In some embodiments, as Figure 3 shown, a socket hole 412 is formed at one end of the piston rod 41 for connecting to the first conductive member 7, and one end of the first conductive member 7 facing the piston rod 41 is inserted into the socket hole 412; or a socket hole 412 is formed at one end of the first conductive member 7 for connecting to the piston rod 41, and one end of the piston rod 41 located in the installation cavity 13 is inserted into the socket hole 412. Among them, the center of the socket hole 412 is located on the axis of the guide rod 71. In the above design, the piston rod 41 and the first conductive member 7 are connected by insertion, and the socket hole 412 and the guide rod 71 are coaxially arranged. In this way, one end of the first conductive member 7 is limited and guided by the second guide hole 81 (shown in Figure 1 ) through the guide rod 71, and the other end is limited and guided by being inserted into the socket hole 412 with the piston rod 41, so that the stability of the first conductive member 7 driving the piston rod 41 to move is better. It can be understood that the socket hole 412 can be formed on the piston rod 41 or on the first conductive member 7, as long as the piston rod 41 and the first conductive member 7 are inserted into each other.

[0051] In some embodiments, the driving member 51 is an elastic member that can generate a driving force when powered on. Specifically, the elastic member is used to generate an elastic force acting on the moving member 4 when the power is connected to drive the moving member 4 to move and open the first through hole 211. The driving member 51 can apply an elastic force to the first conductive member 7 to drive the first conductive member 7 to drive the piston rod 41 to move, thereby driving the cover plate 42 to open the first through hole 211.

[0052] Specifically, the driving member 51 can specifically be set as components such as a spring made of a shape memory alloy material. When the power is turned off, the deformation generated by the driving member 51 being extruded by the upper component is plastic deformation, and at this time, no elastic force is generated, and the first through hole 211 is in a sealed state; when the power is turned on, the temperature of the driving member 51 can rapidly rise to the critical temperature and return to the state before plastic deformation. At this time, the driving member 51 rebounds against the extrusion force of the upper component. Relatively speaking, the driving member 51 can apply an elastic force to components such as the first conductive member 7, and finally drive the movable member 4 to move and open the first through hole 211. In this process, through reasonable design, the temperature of the driving member 51 when powered on can be controlled to remain slightly higher than the critical temperature. In this way, when the power is turned off again, the temperature of the driving member 51 can rapidly drop to the critical temperature, so as to stop applying the elastic force in time.

[0053] In the above design, the driving member 51 is set as an elastic member that can generate a driving force when powered on, specifically referring to an elastic member made of a shape memory alloy material. In this way, the driving member 51 only has elasticity when the power is turned on, realizing the driving function, and can stop driving in time when the power is turned off, with timely response and easy control.

[0054] In some embodiments, such as Figure 1 shown, the atomizer further includes a reset member 52. The reset member 52 is connected to the movable member 4, and the reset member 52 is used to drive the movable member 4 to reset to seal the first through hole 211 when the driving member 51 is powered off. Specifically, the reset member 52 can be set between the cover plate 42 and the limiting bracket 6, and the cover plate 42 is applied with a force to reset it to seal the first through hole 211. Optionally, the reset member 52 can adopt elastic components such as a bias spring and a spring piece to drive the movable member 4 to reset by applying an elastic force; in addition, the reset member 52 can also be a counterweight for increasing weight. When the driving member 51 is powered off, the cover plate 42 is pushed to reset by its own gravity. In the above design, by using the reset member 52 to drive the movable member 4 to reset to seal the first through hole 211 when the driving member 51 is powered off, the reset speed of the movable member 4 can be accelerated, and the first through hole 211 can be sealed in time to prevent the aerosol generation matrix from leaking.

[0055] As Figure 1 shown, an embodiment of the present invention further provides an electronic atomization device, including a battery 9 and the above atomizer. The battery 9 is at least electrically connected to the driving member 51 to supply power to the driving member 51. It can be understood that the battery 9 can be arranged inside the housing 1 of the atomizer or outside the atomizer. In addition to supplying power to the driving member 51, the battery 9 can also supply power to other electronic components of the electronic atomization device. For example, it can supply power to the heating wire on the atomization component 3, and can also supply power to components such as a detection member for detecting the air pressure change in the atomization component 3, etc.

[0056] The electronic atomization device provided by the embodiment of the present utility model adopts the above-mentioned atomizer. Since the atomizer can reduce the waste caused by the leakage of the aerosol-forming substrate and improve the utilization rate of the aerosol-forming substrate, when the atomizer is applied to the electronic atomization device, the leakage of the aerosol-forming substrate inside the electronic atomization device is significantly reduced, the utilization rate of the aerosol-forming substrate is improved, and the usage duration of the electronic atomization device is increased. Moreover, when the housing 1 of the atomizer is made of a transparent material, the storage amount of the internal aerosol-forming substrate can also be visually seen, thereby improving the usage experience of the electronic atomization device.

[0057] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
