[0002] Nebulizers typically generate an aerosol by atomizing the aerosolized substrate in the liquid storage space through the atomizing core in the first airway. Therefore, the liquid storage space must be connected to the first airway to allow the aerosolized substrate to flow from the liquid storage space to the atomizing core. However, during transportation of the nebulizer and when the nebulizer is idle, the connection between the liquid storage space and the first airway can easily lead to leakage. Summary of the Invention

The atomizing core is arranged in the first air duct. The energy storage member is arranged in the second air duct. The movable member is movably installed in the second air duct and is fixedly connected to one end of the energy storage member. The movable member moves in the second air duct under the action of the suction operation and the energy storage member. When the atomizer is in a non-working state, the liquid storage space and the atomizing core are separated by the movable member; when the atomizer is in a working state, the movable member moves upward, and the liquid storage space and the atomizing core are connected via the movable member.

[0005] Optionally, the atomizer further includes a first airflow pipeline, which is arranged in the shell and connected to the outside at both ends. A first air channel is formed in the first airflow pipeline, and an atomizing core is arranged in the first air channel. A first through hole is opened on the side wall of the first airflow pipeline, and the first through hole is used to connect the first air channel and the second air channel. The atomizing core is arranged corresponding to the first through hole.

[0006] Optionally, the atomizer also includes a second air flow pipeline, which is arranged in the outer shell and is mounted outside the first air flow pipeline. Both ends of the second air flow pipeline are connected to the outside world. A second air channel is formed between the second air flow pipeline and the first air flow pipeline. A liquid storage space is formed between the second air flow pipeline and the outer shell. A second through hole corresponding to the first through hole is opened on the side wall of the second air flow pipeline. The second through hole is used to connect the second air channel and the liquid storage space.

[0007] Optionally, the movable part includes a blocking portion and a connecting portion with a connecting hole, and the movable part moves between a first position and a second position in the second air channel. When the movable part is in the first position, the blocking portion blocks the first through hole and the second through hole. When the movable part is in the second position, the connecting hole connects the first through hole and the second through hole to connect the liquid storage space with the first air channel.

[0008] Optionally, the energy storage member is an elastic member, one end of the elastic member is fixedly arranged in the second air channel, and the other end is connected to the movable member.

[0014] The beneficial effects of the present application are as follows: Different from the prior art, in the present application, the user can generate negative pressure when inhaling, that is, generate negative pressure in the outlet direction of the first airway and the second airway. Under negative pressure, a pressure difference can be generated in the second airway. Under the action of the pressure difference, the movable part can move in the second airway and store energy for the energy storage part during the movement. The movement of the movable part can connect the first airway with the liquid storage space, so that the atomized matrix can enter the first airway and the atomized matrix can be atomized. Under negative pressure, air flow can be generated in the first airway, thereby exhausting the aerosol. After the user stops inhaling, the above-mentioned negative pressure disappears, and the energy stored in the energy storage part is released, thereby causing the movable part to move, thereby limiting the connection between the first airway and the liquid storage space to avoid leakage. Through the above method, the movable part in the present application can move under the joint action of the user's suction and the energy storage part, so that the user can automatically connect the liquid storage space and the first air channel during the suction process, and the connection between the liquid storage space and the first air channel can be cut off when the user stops suctioning. There is no need for the user to actively open and close the liquid inlet hole by rotating or pulling up and down, which can greatly improve the convenience of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0022] The nebulizer usually uses the atomizing core in the first air channel to mist the atomized matrix in the liquid storage space to produce an aerosol for inhalation. In this way, the liquid storage space needs to be connected to the first air channel so that the atomized matrix can flow from the liquid storage space to the atomizing core. However, during the transportation of the nebulizer and when the nebulizer is idle, the connection between the liquid storage space and the first air channel is likely to cause leakage. In the related art, many nebulizers use oil core separation or liquid core separation to prevent the liquid storage space from being connected to the first air channel when the nebulizer is not in use. However, the nebulizer in the related art usually requires the user to actively open or close the liquid inlet hole by rotating or pulling up and down to prevent leakage. It is relatively cumbersome in actual use and there is a technical problem of inconvenience in use. In order to improve the above technical problems, the present application can provide the following embodiments, the purpose of which is to realize that the liquid inlet switch of the nebulizer can be automatically realized during the user's inhalation, thereby improving the convenience of using the nebulizer.

[0023] An embodiment of the present application provides an atomizing device, which includes an atomizer 10. In some embodiments, the atomizing device also includes a battery assembly, and the atomizer 10 is electrically connected to the battery assembly, so that the battery assembly can power the atomizer 10 to achieve the atomization function. Optionally, an air inlet channel can be provided on the battery assembly to communicate with the atomizer 10, so that external gas can enter the atomizer 10. The atomizer 10 can also be directly connected to the outside world, which is not specifically limited here. It should be noted that the atomizing device of the present application can be a disposable product or a replaceable non-disposable product. For non-disposable products, the atomizer 10 of the atomizing device can be replaced after use.

[0024] See Figure 1 and Figure 2 , an embodiment of the present application provides a nebulizer 10. The nebulizer 10 includes a housing 11, an energy storage member 15 and a movable member 16. Specifically, the housing 11 has a liquid storage space 20, a first air channel 121 and a second air channel 131. The liquid storage space 20 can store atomized matrix, and the atomized matrix can be atomized into an aerosol under heated conditions for inhalation. Optionally, the atomized matrix can also be stored in the atomization space 20 by arranging liquid storage cotton. The first air channel 121 and the second air channel 131 are both connected to the outside world in two directions. In other words, the first air channel 121 and the second air channel 131 each include an air inlet and an air outlet respectively connected to the outside world. Among them, the first air channel 121 and the second air channel 131 can be connected to the outside world directly or through a channel, which is not specifically limited here. The first air channel 121 and the second air channel 131 are connected to the outside world in two directions, that is, one end of the first air channel 121 can be used for air intake and the other end can be used for air outlet. One end of the second air channel 131 can be used for air intake, and the other end of the second air channel 131 can be used for air discharge. An atomizer core 14 is provided in the first air channel 121. The atomizer core 14 can heat and atomize the atomized matrix to form an aerosol, and the aerosol can be discharged through the first air channel 121. The energy storage member 15 is provided in the second air channel 131. The energy storage member 15 can be, for example, an elastic member such as a spring, or a pneumatic accumulator or a hydraulic accumulator. The energy storage member 15 can convert the energy in the system into compression energy or potential energy and store it at an appropriate time, and can release the energy at an appropriate time. The movable member 16 is movably installed in the second air channel 131 and is connected to one end of the energy storage member 15. The movable member 16 moves in the second air channel 131 under the action of the energy storage member 15. The movable member 16 selectively connects the first air channel 121 with the liquid storage space 20 through movement.

[0025] In the present application, the movable part 16 moves in the second air channel 131 under the action of the suction operation and the energy storage part 15. When the atomizer 10 is in a non-working state, the liquid storage space 20 and the atomizer core 14 are separated by the movable part 16; when the atomizer 10 is in a working state, the movable part 16 moves upward, and the liquid storage space 20 and the atomizer core 14 are connected through the movable part 16. Specifically, when the user is inhaling, a negative pressure can be generated, that is, a negative pressure is generated in the outlet direction of the first air channel 121 and the second air channel 131. Under negative pressure, a pressure difference can be generated in the second air channel 131. Under the action of the pressure difference, the movable part 16 can move in the second air channel 131 and store energy for the energy storage part 15 during the movement. The movement of the movable part 16 can connect the first air channel 121 with the liquid storage space 20, so that the atomized matrix can enter the first air channel 121 and the atomized matrix can be atomized. Under negative pressure, air flow can be generated in the first air channel 121, thereby expelling the aerosol. After the user stops inhaling, the above-mentioned negative pressure disappears, and the energy stored in the energy storage member 15 is released, thereby causing the movable member 16 to move, thereby limiting the connection between the first air channel 121 and the liquid storage space 20 to avoid leakage. Through the above-mentioned method, the movable member 16 in the present application can move under the joint action of the user's inhalation and the energy storage member 15, so that the user can automatically connect the liquid storage space 20 and the first air channel 121 during the inhalation process, and can cut off the connection between the liquid storage space 20 and the first air channel 121 when the user stops inhaling, without the user actively rotating or pulling up and down to switch the liquid inlet, which can greatly improve the convenience of use.

[0026] See Figures 3 to 6In some embodiments, specifically, the housing 11 includes a mouthpiece 111, a shell 112, and a base 113, which are connected in sequence. The interior of the shell 112 can accommodate components of the atomizer 10, such as the atomizer core 14, and the shell 112 also forms the aforementioned liquid storage space 20. Specifically, a seal 19 can be provided at one end of the shell 112 near the mouthpiece 111, and a seal 19 can also be provided at one end of the shell 112 near the base 113. The seal 19 and the side wall of the shell 112 enclose the aforementioned liquid storage space 20. Optionally, the seal 19 can also be part of the mouthpiece 111 or part of the base 113, and no specific limitation is made here. The base 113 is provided with a first air inlet channel 1131 and a second air inlet channel 1132. The first air inlet channel 1131 is connected to the first air channel 121, and the second air inlet channel 1132 is connected to the second air channel 131. The first air channel 121 and the second air channel 131 can be connected to the outside world through the base 113. Optionally, the first air inlet channel 1131 and the second air inlet channel 1132 are provided in the aforementioned sealing member 19. In some embodiments, the second air inlet channel 1132 is an annular air channel or a through hole spaced apart in the circumferential direction, which is not specifically limited herein.

[0027] In some embodiments, the atomizer 10 further includes a first airflow conduit 12, which is disposed in the housing 11 and is connected to the outside at both ends. One end of the first airflow conduit 12 can be used for air intake, and the other end can be used for air discharge. The first airway 121 mentioned above is formed in the first airway 12, and an atomizing core 14 is disposed in the first airway 121. The atomizing core 14 can heat the atomized matrix and atomize it to form an aerosol, and the aerosol can be discharged through the first airway 121. Among them, a first through hole 122 is provided on the side wall of the first airflow conduit 12, and the first through hole 122 is used to connect with the first airway 121 and the second airway 131. The atomizing core 14 is correspondingly arranged with the first through hole 122. The atomized matrix can enter the first airway 121 from the first through hole 122. Since the atomizing core 14 is correspondingly arranged with the first through hole 122, the atomized matrix can enter the atomizing core 14 after passing through the first through hole 122, thereby being atomized by the atomizing core 14.

[0028] In some embodiments, the first airflow conduit 12 is provided through the suction nozzle 111 and is directly connected to the outside world. The first airflow conduit 12 is provided as a complete part through the suction nozzle 111 and is directly connected to the outside world. This ensures the sealing performance of the first airflow conduit 12 during suction, so that the atomizer 10 does not need to add additional parts to ensure the airtightness of the first airflow conduit 12. In other embodiments, the suction nozzle 111 has an air outlet channel connected to the outside world, and the first airflow conduit 12 is connected to the air outlet channel. In this arrangement, the suction nozzle 111 and the first airflow conduit 12 do not have an assembly relationship, so the parts can be manufactured separately from each other, thereby reducing production costs.

[0029] In some embodiments, the atomizer 10 further includes a second airflow conduit 13 disposed within the housing 11 and sleeved outside the first airflow conduit 12. Both ends of the second airflow conduit 13 are in communication with the outside world, and a second air passage 131 is provided between the second airflow conduit 13 and the first airflow conduit 12. One end of the second airflow conduit 13 can be used for air intake into the second air passage 131, and the other end can be used for air exhaust from the second air passage 131. The aforementioned liquid storage space 20 is formed between the second airflow conduit 13 and the housing 11. A second through hole 132 is provided in the sidewall of the second airflow conduit 13. The second through hole 132 is used to connect the second air passage 131 with the liquid storage space 20, and the atomized substrate can flow from the liquid storage space 20 through the second through hole 132. The second through hole 132 is provided corresponding to the first through hole 122, and the movable member 16 can selectively connect the first through hole 122 with the second through hole 132 by movement, thereby connecting the first air passage 121 with the liquid storage space 20. When the movable member 16 connects the first through hole 122 and the second through hole 132 , the atomized substrate can flow from the liquid storage space 20 through the first through hole 122 and the second through hole 132 to the atomizing core 14 in the first air channel 121 .

[0030] In some embodiments, the second airflow conduit 13 is provided through the suction nozzle 111 and is directly connected to the outside world. The second airflow conduit 13 is provided as a complete component through the suction nozzle 111 and is directly connected to the outside world. This ensures the sealing performance of the second airflow conduit 13 during inhalation, so that the atomizer 10 does not need to add additional parts to ensure the airtightness of the second airflow conduit 13. In other embodiments, the suction nozzle 111 has an air outlet channel connected to the outside world, and the second airflow conduit 13 is connected to the air outlet channel. In this configuration, the suction nozzle 111 and the second airflow conduit 13 do not have an assembly relationship, so the parts can be manufactured separately, thereby reducing production costs.

[0031] In some embodiments, combined Figures 3 to 6 Specifically, the movable member 16 includes a blocking portion 161 and a connecting portion 162 having a connecting hole 163. The movable member 16 moves between a first position and a second position in the second air passage 131. When the movable member 16 is in the first position (e.g. Figure 3 and Figure 4As shown), the blocking portion 161 blocks the first through hole 122 and the second through hole 132, preventing the atomized matrix in the liquid storage space 20 from entering the atomizing core 14 of the first air channel 121, thereby achieving liquid-core separation. Specifically, when the user is not inhaling, the movable member 16 is in the first position. When the movable member 16 is in the second position, the connecting hole 163 connects the first through hole 122 and the second through hole 132 to connect the liquid storage space 20 with the first air channel 121, so that the atomized matrix can enter the atomizing core 14 in the first air channel 121 through the first through hole 122, the second through hole 132 and the connecting hole 163. Specifically, when the user inhales, a pressure difference is generated in the second air channel 131, causing the movable member 16 to move to the second position (see Figure 5 and Figure 6 Optionally, a limiter 18 is fixedly disposed in the second air passage 131. The limiter 18 is disposed at a predetermined endpoint of the movable member 16's travel path, thereby limiting further movement of the movable member 16. This allows the movable member 16 to be constrained by the limiter 18 during movement, thereby stably remaining in the first or second position described above. In some embodiments, a sealing ring is disposed on the outer or inner periphery of the movable member 16 to separate the second air passages 131 on either side of the movable member 16, allowing a sufficient pressure differential to be generated during inhalation by the user to cause movement of the movable member 16.

[0032] In some embodiments, the energy storage member 15 is an elastic member, one end of which is fixedly arranged in the second air channel 131, and the other end is connected to the movable member 16. Among them, the energy storage member 15 can be located at the end of the movable member 16 close to the suction nozzle 111, or at the end of the movable member 16 away from the suction nozzle 111, which can be determined according to the specific structure of the atomizer 10 and is not specifically limited here. Taking the energy storage member 15 as a spring and located on the side of the movable member 16 close to the suction nozzle 111 as an example, the working process is exemplarily introduced. When the user is not inhaling, the movable member 16 is in the first position, at which time the spring does not apply tension to the movable member 16, and at this time the blocking portion 161 of the movable member 16 blocks the first through hole 122 and the second through hole 132. When the user is inhaling, a negative pressure is generated on the side of the movable member 16 facing the suction nozzle 111 in the second air channel 131. Under the action of the pressure difference, the movable member 16 moves to the second position, and at this time the spring is compressed to accumulate potential energy. After the movable member 16 moves to the second position, the first through hole 122 and the second through hole 132 can be communicated with each other through the communicating hole 163 , and the atomized substrate can enter the atomizing core 14 of the first air channel 121 and be atomized.

[0033] In some embodiments, a retaining member 17 is fixedly installed in the second air channel 131, one end of the elastic member abuts against the retaining member 17, and the other end is connected to the movable member 16. The retaining member 17 can allow the elastic member to be installed in the second air channel 131. The elastic member can be fixedly connected to the retaining member 17 or abut against the retaining member 17, without specific limitation. The retaining member 17 is also provided with at least one air hole. The retaining member 17 will prevent the air flow in the second air channel 131 when the elastic member is installed. The provision of the air hole can prevent the retaining member 17 from blocking the second air channel 131. Optionally, by setting different numbers of air holes on the retaining member 17, the air flow resistance in the second air channel 131 can be adjusted, so that the number of air holes can be set to match the user's suction force with the elastic force of the elastic member and the resistance of the movable member 16, making it easier for the user to suction.

[0034] The above are merely embodiments of the present application and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
