The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0034] In one embodiment, a nebulizer is provided, including a shell assembly, an atomizing assembly and a valve assembly. A liquid storage chamber is formed in the shell assembly, and the liquid storage chamber is used to store an aerosol matrix; the liquid storage chamber has an injection channel and an air pressure balance channel; the injection channel connects the liquid storage chamber with the injection device; the air pressure balance channel is located outside the injection channel, and connects the liquid storage chamber with the outside of the shell assembly. The atomizing assembly is arranged in the liquid storage chamber, and the atomizing assembly is used to heat the aerosol matrix in the liquid storage chamber to generate an aerosol. The valve assembly is arranged in the liquid storage chamber, and the valve assembly includes a first movable part and a second movable part; the first movable part is arranged at the injection channel, and the first movable part can be pressed by the injection device to open the injection channel; the second movable part is arranged at the air pressure balance channel, and the second movable part can follow the movement of the first movable part to open the air pressure balance channel; when the injection device releases the pressure on the first movable part, the valve assembly closes the liquid storage chamber. In this embodiment, the first movable part drives the second movable part, and the air pressure balance channel can be opened when liquid is injected to balance the air pressure in the liquid storage chamber with the external pressure. When no liquid is injected, the valve assembly can close the liquid storage chamber; even if the user forgets to actively seal the liquid storage chamber, leakage can be avoided.

[0035] Please refer to Figures 1 to 7 In this embodiment, the atomizer 1 mainly includes a housing assembly 10 , an atomizing assembly 20 and a valve assembly 30 .

[0036] The housing assembly 10 can be understood as a component related to the overall outer contour of the atomizer 1. A liquid storage chamber 11 is formed inside the housing assembly 10, which is a space for storing aerosol matrix.

[0037] The shell component 10 has an injection channel 12, which is a structure for allowing an external aerosol matrix to enter the liquid storage chamber 11, and the aerosol matrix can be replenished into the liquid storage chamber 11 through the injection channel 12. The injection channel 12 connects the liquid storage chamber 11 with the outside of the shell component 10. In practical applications, the injection channel 12 will cooperate with an injection device, which is a device for replenishing an aerosol matrix into the liquid storage chamber 11. The aerosol matrix is ​​stored in the injection device and can be injected into the liquid storage chamber 11. Exemplarily, the injection device can have a liquid outlet nozzle that can dock with the injection channel 12, and the liquid outlet nozzle can partially enter the injection channel 12 and inject the aerosol matrix into the injection channel 12. That is, one end of the injection channel 12 is connected to the outside of the shell component 10, and the other end is connected to the inside of the liquid storage chamber 11.

[0038] In some embodiments, the housing assembly includes a housing body 13 and a pipe member 14. The housing body 13 can be regarded as a main component of the housing assembly, which mainly forms a liquid storage chamber 11. The injection channel 12 is a space formed inside the pipe member 14. Figure 1 to Figure 2As shown, the pipe member 14 can be fixed to the shell body 13 and embedded in the shell body 13; illustratively, the pipe member 14 can be fixed to the shell body 13 at the end by riveting or the like. The injection channel 12 inside the pipe member 14 can serve as a setting space for the first movable member 31. The first movable member 31 is set inside the pipe member 14, and the first movable member 31 can move along the pipe member 14. The first movable member 31 is arranged in the injection channel 12 and moves in the directions of the opposite ends of the injection channel 12. Exemplarily, the pipe member 14 can be cylindrical, and the injection channel 12 formed inside it is a cylindrical space. The axial ends of the injection channel 12 connect the outside of the shell assembly 10 and the liquid storage chamber 11. The first movable member 31 is arranged in the injection channel 12 and can move in the axial direction.

[0039] The shell assembly 10 also has an air pressure balance channel 15, which is used to balance the air pressure inside the liquid storage chamber 11 with the environment outside the shell. When the aerosol matrix is ​​replenished, the gas in the liquid storage chamber 11 can be discharged through the air pressure balance channel 15. The air pressure balance channel 15 is located outside the liquid injection channel 12, that is, in this embodiment, the gas channel is separated from the aerosol matrix channel, which can ensure smooth gas discharge and reduce leakage. In addition, separating the air pressure balance channel 15 from the liquid injection channel 12 can make the first movable part 31 and the liquid injection channel 12 fit more closely, for example, the first movable part 31 and the liquid injection channel 12 have a higher degree of fit, no looseness will occur, the structure is more stable, and smooth liquid injection is also guaranteed.

[0040] The air pressure balance channel 15 can be independent of the injection channel 12 and arranged at a certain distance from the injection channel 12. The air pressure balance channel 15 can also be arranged beside the injection channel 12 to shorten the distance between the two, which is conducive to simplifying the structure of the valve assembly 30.

[0041] In some embodiments, the air pressure balance channel 15 can be formed by the cooperation of the pipe member 14 and the shell body 13. Figure 3 to Figure 4 As shown, an air pressure balance channel 15 is formed between the outer wall of the pipe member 14 and the inner wall of the shell body 13. At this time, the interior of the pipe member 14 is the injection channel 12, and the air pressure balance channel 15 is formed around the outer wall. The side wall of the pipe member 14 serves as a partition between the injection channel 12 and the air pressure balance channel 15. The structure inside the liquid storage chamber 11 is simple and easy to manufacture. For ease of explanation, the embodiments of the present application all take the form of forming the air pressure balance channel 15 between the outer wall of the pipe member 14 and the inner wall of the shell body 13 as an example. In other embodiments, the air pressure balance channel 15 can also be formed by other structures, such as being completely based on the structure of the shell body 13. As shown in FIG. Figure 5As shown, in this embodiment, the air pressure balance channel 15 has a plurality of openings communicating with the outside on the surface of the shell body 13 , and these openings are circumferentially distributed beside the pipeline member 14 .

[0042] The atomizer assembly 20 is used to heat the aerosol matrix in the liquid storage chamber 11 to produce an aerosol. Exemplarily, the atomizer assembly 20 may include a housing 21 and a heating assembly 22; in some examples, the heating assembly 22 may include a liquid storage member 221 and a heating member 222, and the liquid storage member 221 is used to store the aerosol matrix so that the aerosol matrix can be kept next to the heating member 222. The liquid storage member 221 may be a porous matrix such as a liquid storage cotton, and the porous structure thereof is used to store the aerosol matrix; the liquid storage member 221 may also be other forms of structures capable of storing aerosol matrices. While storing the aerosol matrix, the liquid storage member 221 can also block the passage of the aerosol matrix to a certain extent to prevent the aerosol matrix from leaking directly. An airflow channel may be formed inside the liquid storage member 221, and the airflow channel is used for the airflow and aerosol to enter and exit. The heating element 222 may be disposed in the air flow channel. The heating element 222 is used to heat the aerosol matrix stored in the liquid storage element 221 to generate aerosol when powered on. The generated aerosol is discharged from the air flow channel along with the air flow to be used.

[0043] The valve assembly 30 is a structure for controlling whether the liquid storage chamber 11 is closed. In this embodiment, the valve assembly 30 can automatically close the liquid storage chamber 11, so that the aerosol matrix in the liquid storage chamber 11 will not leak out when the user does not replenish the aerosol matrix in the liquid storage chamber 11. The valve assembly 30 can control whether the liquid storage chamber 11 is closed by controlling the closing and opening of the injection channel 12 and the air pressure balance channel 15.

[0044] The valve assembly 30 includes a first movable member 31, which is disposed at the injection channel 12 and can be pressed by the injection device to open the injection channel 12. The first movable member 31 is a structure for controlling the closing and opening of the injection channel 12. When the injection device presses the first movable member 31, the first movable member 31 can be moved to a position to open the injection channel 12; and when the injection device releases the pressure on the first movable member 31, the first movable member 31 will return to a position to close the injection channel 12.

[0045] In some embodiments, the first movable member 31 includes a liquid injection portion 311, and a connecting channel 312 is formed in the liquid injection portion 311. The liquid injection portion 311 has two opposite ends, one of which has a liquid inlet 313. The liquid inlet 313 is an end close to the outside of the housing assembly 10 and connected to the outside of the housing assembly 10. When the liquid injection device presses against the first movable member 31, the aerosol matrix flowing out of the liquid injection device can enter the connecting channel 312 of the liquid injection portion 311 through the liquid inlet 313. A first liquid outlet 314 is provided on the side wall of the liquid injection portion 311, and the first liquid outlet 314 is connected to the liquid inlet 313, so that the aerosol matrix injected into the connecting channel 312 can flow out through the first liquid outlet 314. When the injection device presses against the first movable part 31, the first liquid outlet 314 is connected to the liquid storage chamber 11, and the aerosol matrix can be replenished to the liquid storage chamber 11; when the injection device releases the pressure on the first movable part 31, the liquid supply channel is closed, and the first liquid outlet 314 is disconnected from the liquid storage chamber 11.

[0046] In some embodiments, the first movable member 31 further includes a sealing portion 315; the sealing portion 315 is disposed at the other end of the liquid injection portion 311 and is used to cooperate with the inner wall of the liquid injection channel 12 to close the liquid injection channel 12. Figure 3 As shown, the sealing part 315 cooperates with the inner wall of the pipe member 14 to close the injection channel 12; it can be understood that the closure of the injection channel 12 means that the aerosol matrix cannot enter the injection channel 12, and the aerosol matrix in the injection channel 12 cannot enter the liquid storage chamber 11. In this embodiment, when the first liquid outlet 314 of the first movable part 31 is inside the pipe member 14 and is blocked by the pipe member 14, the injection channel 12 is also considered to be closed; the sealing part 315 is provided at the end of the first movable part 31, which can provide a better sealing effect and avoid leakage. Exemplarily, the sealing part 315 may include a rubber ring and other structures for sealing.

[0047] In some embodiments, the valve assembly 30 includes a first elastic member 32, which is used to provide an elastic force that causes the first movable member 31 to move toward the outside of the liquid storage chamber 11, so that the first movable member 31 closes the injection channel 12. When the injection device presses against the first movable member 31, the first elastic member 32 undergoes corresponding elastic deformation and accumulates elastic potential energy; when the injection device releases the pressure on the first movable member 31, the elastic force of the first elastic member 32 causes the first movable member 31 to return to the position of closing the injection channel 12.

[0048] The first elastic member 32 may be an elastic connecting member such as a spring. The first elastic member 32 has two opposite ends, one end of which is connected to the first movable member 31, and the other end of which may be directly connected to the injection channel 12. Figure 3 and Figure 4One end of the first elastic member 32 may be connected to the bottom of the pipe member 14. When the liquid injection device presses against the first movable member 31, the first elastic member 32 is compressed, and the first movable member 31 moves toward the direction close to the inside of the liquid storage chamber 11. When the liquid injection device is removed, the first elastic member 32 pushes the first movable member 31 to restore its position. In other embodiments, the first elastic member 32 may not be directly connected to the first movable member 31, and it is also feasible to indirectly drive the first movable member 31 by setting a transmission structure or the like.

[0049] The valve assembly 30 also includes a second movable member 33, which is arranged at the air pressure balance channel 15 and is a structure for controlling the closing and opening of the air pressure balance channel 15. The second movable member 33 can follow the movement of the first movable member 31, so that the air pressure balance channel 15 is opened when the liquid injection device presses the first movable member 31, so as to achieve the effect of timely balancing the air pressure while injecting the aerosol matrix. When the liquid injection device releases the pressure on the first movable member 31, the second movable member 33 will return to the position of closing the air pressure balance channel 15. The first movable member 31 and the second movable member 33 close the liquid injection channel 12 and the air pressure balance channel 15 respectively, so that the liquid storage chamber 11 is closed. When there is no injection, the aerosol matrix does not leak directly due to the liquid injection channel 12 and the air pressure balance channel 15. The second movable member 33 can be in direct contact with the first movable member 31, or it can be indirectly driven by the first movable member 31 through a transmission structure and other structures to achieve the effect of following the movement of the first movable member 31.

[0050] In some embodiments, the second movable member 33 is provided with a second liquid outlet 331, and the second liquid outlet 331 is connected to the liquid storage chamber 11. The first movable member 31 and the second movable member 33 can generate relative movement, so that the first liquid outlet 314 and the second liquid outlet 331 are connected, then the injection channel 12 is opened, and the connecting channel 312 of the first movable member 31 will be connected to the liquid storage chamber 11, and the aerosol matrix can be replenished into the liquid storage chamber 11. In other words, the movement between the second movable member 33 and the first movable member 31 may not be completely synchronized, for example, the second movable member 33 may start to follow the movement of the first movable member 31 only after the first movable member 31 moves a certain distance; it can ensure that the air pressure balance channel 15 is correctly opened after the injection device is pressed in place, reducing the risk of leakage. When the injection device does not press the first movable member 31, the first liquid outlet 314 and the second liquid outlet 331 can be in a staggered state, and the two are not connected, blocking the passage of the aerosol matrix.

[0051] like Figure 6As shown, in some embodiments, a receiving groove 332 is formed inside the second movable member 33; the receiving groove 332 has a groove bottom and a side wall, and the second liquid outlet 331 is arranged on the side wall. The first movable member 31 can enter the receiving groove 332 under the pressure of the liquid injection device, and press against the groove bottom of the receiving groove 332 to drive the second movable member 33 and make the first liquid outlet 314 communicate with the second liquid outlet 331. When the liquid injection device releases the pressure on the first movable member 31, the first movable member 31 may not enter the receiving groove 332, or only partially enter the receiving groove 332 without pressing against the groove bottom. The provision of the receiving groove 332 makes the relative position between the first movable member 31 and the second movable member 33 more stable, ensuring that the first liquid outlet 314 and the second liquid outlet 331 are aligned and connected.

[0052] It should be noted that the shapes of the first liquid outlet 314 and the second liquid outlet 331 can be arbitrary, and the sizes of the first liquid outlet 314 and the second liquid outlet 331 can also be different, which can be set according to actual needs. In practical applications, the injection rate of the aerosol matrix can also be controlled by controlling the size of the first liquid outlet 314 and the second liquid outlet 331. In this embodiment, the first liquid outlet 314 and the second liquid outlet 331 are circular holes of the same size as an example.

[0053] In some embodiments, the second movable member 33 includes a pressing portion 333 and a closing portion 334. The pressing portion 333 is located in the direction in which the first movable member 31 moves along the injection channel 12 toward the inside of the liquid storage chamber 11. When the first movable member 31 is pressed by the injection device, the first movable member 31 can press against the pressing portion 333 of the second movable member 33, so that the second movable member 33 moves with the first movable member 31. The pressing portion 333 can be the accommodating groove 332 of the aforementioned example. In other embodiments, the pressing portion 333 can also be in other forms. The closing portion 334 is a structure for the second movable member 33 to close the air pressure balance channel 15. The closing portion 334 is connected to the pressing portion 333 so that it can move with the pressing portion 333. The first movable member 31 presses against the pressing portion 333 to drive the closing portion 334, thereby opening the air pressure balance channel 15.

[0054] like Figure 6 As shown, the closing portion 334 may be a structure protruding from the receiving groove 332, and is circumferentially located on the outer wall of the receiving groove 332. An air pressure balance channel 15 is formed between the inner wall of the shell body 13 and the outer wall of the pipe member 14, and the closing portion 334 cooperates with the inner wall of the shell body 13 to block the air pressure balance channel 15. The closing portion 334 may be a structure such as a rubber ring for sealing provided on the outer wall of the receiving groove 332. Figure 4As shown, after the first movable member 31 drives the second movable member 33 to move, the closing portion 334 opens the air pressure balance channel 15. By arranging the pressing portion 333 of the second movable member 33 in the moving direction of the first movable member 31, and the closing portion 334 is circumferentially arranged, the first movable member 31 can be pressed against the center of the second movable member 33, and the second movable member 33 follows the movement of the first movable member 31 more stably, and the second movable member 33 itself is not prone to skewing or displacement.

[0055] In some embodiments, the second movable part 33 also includes a guide part 335 connected to the closing part 334; the guide part 335 is located in the air pressure balance channel 15 and is arranged around the outer wall of the pipe part 14. During the movement of the second movable part 33, the guide part 335 is always sleeved on the outside of the pipe part 14, ensuring that the movement direction of the second movable part 33 is always along the setting direction of the pipe part 14 (that is, the direction of the two ends of the injection channel 12), and no offset or misalignment occurs. It can also ensure that after the pressure on the first movable part 31 is released, the second movable part 33 can accurately return to its original position. The guide part 335 can circumferentially surround the pipe part 14, or it can be a guide structure such as a plurality of guide strips arranged at intervals in the circumferential direction of the pipe part 14. As long as it can cooperate with the outer wall of the pipe part 14, it can ensure that the position of the second movable part 33 does not deviate left or right (in the direction shown in the figure).

[0056] In some embodiments, a sealing structure 141 is provided between the guide portion 335 and the outer wall of the pipe member 14, and the sealing structure 141 may be a rubber ring or other structure for sealing. The sealing structure 141 may be provided on the guide portion 335 or on the outer wall of the pipe member 14. By providing an additional sealing structure 141 between the guide portion 335 and the outer wall of the pipe member 14, the injection channel 12 and the air pressure balance channel 15 can be better isolated inside the liquid storage chamber 11, and the aerosol matrix entering the air pressure balance channel 15 and causing leakage are reduced.

[0057] In some embodiments, the valve assembly 30 includes a second elastic member 34, which is used to provide an elastic force that causes the second movable member 33 to move toward the outside of the liquid storage chamber 11, so that the second movable member 33 closes the air pressure balance channel 15. When the second movable member 33 moves with the first movable member 31, the second elastic member 34 undergoes corresponding elastic deformation to accumulate elastic potential energy; when the injection device releases the pressure on the first movable member 31, the elastic force of the second elastic member 34 causes the second movable member 33 to return to the position of closing the injection channel 12. The first elastic member 32 and the second elastic member 34 provide elastic forces to the first movable member 31 and the second movable member 33 respectively, which can ensure that the first movable member 31 and the second movable member 33 can accurately return to their positions and have good stability.

[0058] The second elastic member 34 may be an elastic connecting member such as a spring. The second elastic member 34 has two opposite ends, one end of which is connected to the second movable member 33, and the other end of which may be directly connected to the housing body 13 or the atomizing assembly 20. Figure 4 As shown, one end of the second elastic member 34 can be connected to the closed portion 334 of the second movable member 33. When the second movable member 33 moves with the first movable member 31, the second elastic member 34 is compressed, and the second movable member 33 moves toward the direction close to the inside of the liquid storage chamber 11. When the injection device is removed, the first elastic member 32 pushes the first movable member 31 to restore its position, and the second elastic member 34 can also push the second movable member 33 to restore its position. In other embodiments, the second elastic member 34 can also be connected to other parts of the second movable member 33, such as the outer wall of the receiving groove 332; the second elastic member 34 may not be directly connected to the second movable member 33, and it is also feasible to indirectly drive the second movable member 33 by setting a transmission structure or the like.

[0059] In some embodiments, the second elastic member 34 may be connected to the housing 21 of the atomizer assembly 20. Figures 1 to 4 As shown, a support portion 211 is provided on the outer wall of the housing 21 of the atomizer assembly 20, and the support portion 211 protrudes outward as a structure connected to the second elastic member 34. The second elastic member 34 is connected to the support portion 211 provided on the atomizer assembly 20, and in some implementation processes, the setting length of the second elastic member 34 can be shortened, that is, the second elastic member 34 does not need to extend to the bottom of the liquid storage chamber 11 and is connected to the shell body 13; it can save costs and is easy to install. Of course, in other embodiments, a similar support structure can also be formed on the inner wall of the shell body 13, so that the second elastic member 34 does not need to extend to the bottom of the liquid storage chamber 11.

[0060] The atomizer 1 of this embodiment can be a top-filling atomizer 1, such as Figure 7 As shown, in some embodiments, the atomizer 1 also includes a nozzle structure 40 connected to the atomizer assembly 20. The nozzle structure 40 can be connected to the airflow channel in the atomizer assembly 20, and the generated aerosol is discharged from the nozzle structure 40 along with the airflow. The nozzle structure 40 can be connected to the shell assembly 10 by means of structures such as snaps, and the nozzle structure 40 covers a portion of the surface of the shell assembly 10. In this embodiment, the connection between the injection channel 12 and the air pressure balance channel 15 and the outside of the shell assembly 10 is located in the space enclosed by the nozzle structure 40 and the shell assembly 10. In short, the nozzle structure 40 will block the connection between the injection channel 12 and the air pressure balance channel 15 and the outside of the shell assembly 10.

[0061] In some embodiments, an atomization device is further provided, comprising the atomizer 1 of the above embodiment and a power supply assembly, wherein the atomizer 1 is electrically connected to the power supply assembly.

[0062] The power supply assembly is used to provide power to the atomizing assembly 20 in the atomizer 1. The atomizer 1 and the power supply assembly may be fixedly connected or detachably connected. The above-mentioned atomizing device is only one embodiment of the present application, and the specific internal structure of the atomizing device is not repeated.

[0063] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
