[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0030] In combination with Figures 1 to 3, an embodiment of the present application provides an atomizing device 1. The atomizing device 1 includes a housing 10, an atomizing component 30, and a driving component 40. The housing 10 has a liquid storage space 100. The atomizing component 30 is disposed within the housing 10, and the housing 10 and the atomizing component 30 enclose to form a liquid storage space 100. The liquid storage space 100 can be used to store an aerosol matrix. The atomizing component 30 includes an atomizing duct 31, and the atomizing duct 31 is provided with a liquid inlet hole 311 for the aerosol matrix in the liquid storage space 100 to enter. The driving component 40 is connected to one end of the atomizing component 30, and the driving component 40 is configured to drive the atomizing component 30 to move relative to the housing 10 according to the state of an airflow sensor, so as to selectively conduct or cut off the liquid inlet hole 311 from the liquid storage space 100. For example, when the liquid inlet hole 311 is above the bottom wall of the liquid storage space 10, the liquid inlet hole 311 is in communication with the liquid storage space 10. When the liquid inlet hole 311 is below the bottom wall of the liquid storage space 10, the liquid inlet hole 311 is cut off from the liquid storage space 10. In the embodiment of the present application, the movable connection includes a rotational connection and a translational connection, and the type of movement refers to translation or rotation. The atomizing component 30 moves relative to the housing 10, that is, the atomizing component 30 rotates and / or moves relative to the housing 10, and the type of movement is specifically defined here. In this embodiment, when the airflow sensor senses a change in the air pressure inside the atomizing device 1, the circuit board of the atomizing device 1 is activated to enter the working state, and the circuit board sends a control signal to drive the atomizing component 30 to move relative to the housing 10, so that the liquid inlet hole 311 is in communication with the liquid storage space 100. When the circuit board detects that the user has not puffed for a certain period of time, the circuit board sends a control signal to drive the atomizing component 30 to move relative to the housing 10, so that the liquid inlet hole 311 is cut off from the liquid storage space 100. The circuit board detecting that the user has not puffed for a certain period of time can be achieved by the induction of the airflow sensor or by other means, which is not specifically defined here.

[0031] Through the above method, it is possible to realize that the atomizing component moves upward or downward by electric control, thereby realizing the activation or closing of the adaptive automatic control of the liquid core separation. The problem of liquid leakage in the atomizing device 1 during user use can be effectively solved. When the user uses the product, the liquid core separation can be automatically activated, and when the user does not use the product, the liquid core separation can be automatically reset, improving the quality and reliability of the product.

[0032] In some embodiments, the atomizing device 1 further includes a seal 50. The seal 50 is disposed within the housing 10 and is sealed between the inner wall of the housing 10 and the outer wall of the atomizing duct 31. The seal 50 and the inner wall of the housing 10 and the atomizing duct 31 define a liquid storage space 100. The atomizing assembly 30 is movably connected to the seal 50 to selectively communicate the liquid inlet hole 311 with the liquid storage space 100 or block the liquid inlet hole 311 through the seal 50. On the one hand, the seal 50 can serve as a part of the liquid storage space 100, and on the other hand, it has the ability to block the liquid inlet hole 311. The atomizing assembly 30 is movably connected to the seal 50. For example, the atomizing assembly 30 can move relative to the seal 50 or rotate relative to the seal 50, which is not specifically limited herein. The atomizing assembly 30 can change the position of cooperation with the seal 50 through movement. Optionally, the seal 50 is provided with a through hole for the atomizing assembly 30 to pass through, and the atomizing assembly 30 is movably connected to the seal 50 through the through hole.

[0033] In some embodiments, the housing 10 includes an air outlet channel. One end of the atomizing assembly 30 is movably engaged with the air outlet channel, and the other end of the atomizing assembly 30 is movably engaged with the seal 50. A sealing silicone can also be provided between the air outlet channel and the atomizing assembly 30. In the above manner, a stable and sealed movable connection between the atomizing assembly 30 and the housing 10 and the seal 50 can be achieved, reducing the occurrence of liquid leakage.

[0034] In some embodiments, the atomizing assembly 30 includes an atomizing duct 31 and an atomizing core 32. The atomizing core 32 is disposed within the atomizing duct 31. The outer wall of the atomizing duct 31 can form a liquid storage space 100 with the housing 10 and the seal 50. The atomizing duct 31 is provided with a liquid inlet hole 311. Through the movement of the atomizing assembly 30, the liquid inlet hole 311 can supply the aerosol matrix to flow from the liquid storage space 100 into the atomizing core 32. Through the movement of the atomizing assembly 30, the liquid inlet hole 311 can also be blocked by the seal 50.

[0035] In some embodiments, a sealing protrusion protrudes within the through hole of the seal 50. When the liquid inlet hole 311 is in communication with the liquid storage space 100, the liquid inlet hole 311 is located on the side of the sealing protrusion close to the liquid storage space 100. When the liquid inlet hole 311 is closed by the seal 50, the liquid inlet hole 311 is located on the side of the sealing protrusion away from the liquid storage space 100. The sealing protrusion can abut against the atomizing duct 31, thereby reducing the leakage of the aerosol matrix from the through hole of the seal 50.

[0036] Further, one end of the driving component 40 is connected to the atomizing component 30. The driving component 40 is used to drive the atomizing component 30 to move relative to the seal 50, so as to selectively communicate the liquid inlet hole 311 with the liquid storage space 100 or block the liquid inlet hole 311 through the seal 50. By providing the driving component 40 and the atomizing component 30 in a driving connection, the atomizing component 30 can be made to move relative to the seal 50 under the action of the driving component 40. In this way, the atomizing duct 31 can be sealed by the seal 50 or communicated with the liquid storage space 100 through relative movement. The driving component 40 can make the atomizing component 30 automatically move relative to the seal 50, thus avoiding the need for the user to manually activate the atomizing device 1 during use.

[0037] In some embodiments, the atomizing device 1 further includes a circuit board (not shown in the figure) and an air flow sensor 80. The air flow sensor 80 is electrically connected to the circuit board, and the circuit board is electrically connected to the driving component 40. When the air flow sensor 80 senses a change in air pressure, the circuit board can issue a control command to control the moving direction of the atomizing component 30. In the above manner, when the air flow sensor 80 senses that the user is sucking, the circuit board can identify the sucking and then control the movement of the atomizing component 30, so that the liquid inlet hole 311 is communicated with the liquid storage space 100, enabling the atomizing device 1 to work properly. Further, the circuit board can also detect whether the air flow sensor 80 is in an inactive state for a long time, so as to determine whether the atomizing device 1 is idle. When the atomizing device 1 is idle, the circuit board can control the movement of the atomizing component 30 to block the liquid inlet hole 311 by the seal 50, thereby isolating the atomizing core 32 from the aerosol matrix and reducing the occurrence of liquid leakage.

[0038] Specifically, in some embodiments, further combined with Figures 4 to 6 , the atomizing device 1 further includes a base 60. The base 60 is mounted on the housing 10. The seal 50 is located between the housing 10 and the base 60, and the driving component 40 passes through the base 60. The base 60 can support the driving component 40 and jointly define the position of the seal 50 with the housing 10. The base 60 is provided with a mounting hole for the driving component 40 to pass through.

[0039] Further, combined with Figure 7 and Figure 8, the driving assembly 40 includes a driving base 42 and a driving device 41. The driving base 42 is movably connected to the base 60. The driving device 41 is installed on the base 60, and the driving shaft of the driving device 41 extends into the base 60 and is drivingly connected to the driving base 42. Among them, the driving device 41 can be a rotary motor or a linear motor, etc., and no specific limitation is made here. The driving shaft of the driving device 41 can extend into the base 60 through the mounting hole and be connected to the driving base 42. The connection between the driving shaft and the driving base 42 can be a threaded connection, welding or bonding, etc., and no specific limitation is made here. In some embodiments, the driving base 42 cooperates with the base 60 and the driving device 41 to be able to change the type of movement of the driving shaft transmitted to the atomizing assembly 30. For example, the rotation of the driving device 41 is changed into the movement of the driving base 42, so that the driving base 42 can drive the atomizing assembly 30 to move. The driving base 42 is connected to the atomizing pipe 31, such as snap connection, interference fit or bonding, welding, etc., and no specific limitation is made here. The driving base 42 can drive the atomizing pipe 31 to move during the movement process.

[0040] In some embodiments, at least one side of the driving base 42 is arranged in a plane, and the driving base 42 abuts against the base 60 through parallel planes to limit the relative rotation of the driving base 42 with respect to the base 60. By setting the driving base 42 and the base 60 to be in plane contact, the rotation of the driving base 42 can be limited, so that the driving base 42 and the base 60 form a sliding pair rather than a rotating pair, that is, the driving base 42 can move relative to the base 60 rather than rotate.

[0041] In some embodiments, the driving assembly 40 further includes a mounting base, and the driving device 41 is installed on the mounting base. The mounting base and the base 60 are also provided with a mutually cooperating snap structure, and the mounting base can mount the driving device 41 on the base 60.

[0042] In some embodiments, an installation space is formed between the base 60 and the seal 50, and at least part of the driving base 42 and the atomizing assembly 30 is located in the installation space. The base 60 is provided with a pin hole 61 and an air flow sensing hole 62 in a penetrating manner. An air flow sensor 80 is further provided on one side of the base 60 facing away from the installation space, and the air flow sensing hole 62 is communicated with the air flow sensor 80. The pins of the atomizing core 32 can pass through the installation space and the pin hole 61 and penetrate out, so as to be connected to the circuit board. The user's suction can generate negative pressure, and then pass through the atomizing pipe 31, the installation space and the air flow sensing hole 62 to be transmitted to the air flow sensor 80, so that the atomizing device 1 can sense the user's suction. In some embodiments, the pin hole 61 and the air flow sensing hole 62 are arranged opposite to each other with reference to the driving assembly 40, so as to reduce the mutual influence between the pin wiring and the air flow sensing function.

[0043] In some embodiments, an installation space is formed between the base 60 and the seal 50. The drive base 42 is provided with a communication hole 421, a wire passing hole 422, and an air passing hole 423. The communication hole 421 communicates with the atomization assembly 30, the wire passing hole 422 communicates the communication hole 421 with the installation space, and the air passing hole 423 communicates the communication hole 421 with the installation space. In other words, the drive base 42 can achieve the function of a "three-way". The pins can pass through the drive base 42 from the communication hole 421 and the wire passing hole 422 into the installation space. The airflow can pass through the drive base 42 into the atomization assembly 30 at least through the air passing hole 423 and the communication hole 421. Optionally, the wire passing hole 422 and the air passing hole 423 are respectively arranged on opposite sides of the communication hole 421 to reduce the mutual interference between wire passing and air intake.

[0044] Further, after passing through the drive base 42 from the communication hole 421 and the wire passing hole 422 into the installation space, the pins pass through the pin hole 61 and extend out of the base 60.

[0045] In some embodiments, combined with Figure 2 , a flange 11 is provided on one side of the housing 10 close to the seal 50, and a retaining piece 70 is provided on one side of the seal 50 close to the liquid storage space 100. The retaining piece 70 abuts against the flange 11 to limit the movement of the seal 50 towards the liquid storage space 100. In other words, a stepped structure is provided on one side of the housing 10 close to the seal 50. The flange 11 can abut against the retaining piece 70 to generate a limiting force, and the retaining piece 70 can transmit the limiting force to the seal 50 to reduce the displacement of the seal 50 during the movement of the atomization assembly 30.

[0046] Further, the hardness of the retaining piece 70 is higher than that of the seal 50. The retaining piece 70 can be made of a metal material. The higher hardness of the retaining piece 70 results in less deformation during the limiting process, so that the limiting force can be transmitted to different positions of the seal 50 more evenly, thereby reducing the deformation of the seal 50 during the movement of the atomization assembly 30.

[0047] In some embodiments, a positioning convex portion 51 protrudes from the seal 50 towards the liquid storage space 100, and the retaining piece 70 is provided with a positioning hole. The positioning convex portion 51 cooperates with the positioning hole to position the position of the retaining piece 70 relative to the seal 50. By providing the positioning convex portion 51, the position of the retaining piece 70 can be positioned, which is beneficial to the assembly of the atomization device 1.

[0048] In some embodiments, an installation protrusion 63 is provided on one side of the base 60 facing the seal 50, and an installation groove 52 is provided on one side of the seal 50 facing the base 60. The installation protrusion 63 cooperates with the installation groove 52 to mount the seal 50 on the base 60. By providing the installation protrusion 63 and the installation groove 52, the seal 50 can be mounted on the base 60, so that when assembling, the seal 50 and the base 60 can be assembled first, and then the whole can be assembled with the housing 10. On the other hand, by providing the installation protrusion 63 and the installation groove 52, the movement of the seal 50 towards the base 60 can be restricted.

[0049] Among them, the movement of the seal 50 in one direction is limited by the baffle 70 and the flange 11, and the movement in the other direction is limited by the base 60, so that the seal 50 can be stably installed, reducing the occurrence of liquid leakage.

[0050] In some embodiments, the atomization device 1 further includes a bottom case 20. The bottom case 20 and the housing 10 enclose the drive assembly 40, the atomization assembly 30, the base 60 and the seal 50. The bottom case 20 and the housing 10 also enclose a receiving space for installing a battery. The bottom case 20 can be connected to the housing 10 by means of snap connection, bonding or threaded connection, etc. The cooperation of the bottom case 20 and the housing 10 can protect the internal base 60, seal 50, atomization assembly 30 and battery. Optionally, in a direction perpendicular to the axis of the atomization assembly 30, the battery is arranged side by side with the atomization assembly 30. In other words, the battery is side-mounted relative to the atomization assembly 30, the base 60 and the seal 50.

[0051] The above are only embodiments of the present application, and do not limit the patent scope of the present application accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
