Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The nebulizer typically mists the nebulized matrix in the reservoir space through a nebulizing cartridge in the first airway to generate an aerosol for inhalation. Such that the liquid storage space needs to be in communication with the first air passage so that the atomizing substrate can flow from the liquid storage space to the atomizing wick. However, during transportation of the atomizer and when the atomizer is idle, the liquid storage space is communicated with the first air passage, so that the liquid leakage phenomenon is easily caused. In the related art, many atomizers adopt an oil core separation or a liquid core separation mode to prevent the liquid storage space from being communicated with the first air channel when the atomizer is not in use, thereby preventing liquid leakage. However, in the related art, the atomizer usually needs to be actively opened or closed by a user through a rotation or up-and-down pulling manner so as to prevent liquid leakage, which is complicated in the actual use process and has the technical problem of inconvenient use. In order to improve the technical problems, the application can provide the following embodiments, and the purpose is to realize that the liquid inlet switch of the atomizer can be automatically realized in the process of sucking by a user, so that the convenience in using the atomizer is improved.

An embodiment of the present application provides an atomizing device comprising an atomizer 10. In some embodiments, the aerosolization device further includes a battery assembly, and the aerosolization 10 is electrically connected to the battery assembly, thereby enabling the battery assembly to power the aerosolization 10 to perform the aerosolization function. Alternatively, an air intake passage may be provided in the battery pack to communicate with the atomizer 10, so that external air can enter the atomizer 10. The atomizer 10 may be directly connected to the outside, and is not particularly limited herein. It should be noted that the atomizing device of the present application may be a disposable product or a replaceable non-disposable product. For non-disposable products, the atomizer 10 of the atomizer device can be replaced after use.

Referring to fig. 1 and 2, an embodiment of the present application provides an atomizer 10. The atomizer 10 comprises a housing 11, an energy storage member 15 and a movable member 16. Specifically, the housing 11 has a liquid storage space 20 therein, a first air passage 121 and a second air passage 131. The reservoir 20 is capable of storing an aerosol matrix that is capable of atomizing into an aerosol under heated conditions for aspiration. Alternatively, the nebulized matrix may be stored in the nebulizing space 20 by providing a liquid reservoir of cotton. The first air passage 121 and the second air passage 131 are both in communication with the outside in both directions. In other words, the first air passage 121 and the second air passage 131 each include an air inlet and an air outlet that communicate with the outside, respectively. The first air passage 121 and the second air passage 131 may be directly connected to the outside, or may be connected to the outside through a channel, which is not particularly limited herein. The first air passage 121 and the second air passage 131 communicate with the outside in two directions, that is, one end of the first air passage 121 can be used for air intake and the other end can be used for air exhaust. One end of the second air passage 131 can be used for air intake, and the other end of the second air passage 131 can be used for air outlet. An atomizing core 14 is arranged in the first air passage 121, the atomizing core 14 can heat and atomize an atomized substrate to form aerosol, and the aerosol can be discharged through the first air passage 121. The energy storage member 15 is disposed in the second air passage 131, and the energy storage member 15 may be an elastic member such as a spring, or may be a pneumatic energy storage or a hydraulic energy storage. The energy storage member 15 is capable of converting energy in the system into compression energy or potential energy at an appropriate timing for storage, and is capable of releasing the energy at an appropriate timing. The movable piece 16 is movably installed in the second air passage 131 and is connected with one end of the energy storage piece 15, the movable piece 16 generates movement in the second air passage 131 under the action of the energy storage piece 15, and the movable piece 16 selectively communicates the first air passage 121 with the liquid storage space 20 through movement.

In the application, the movable part 16 moves in the second air passage 131 under the action of the sucking operation and the energy storage part 15, and when the atomizer 10 is in a non-working state, the liquid storage space 20 and the atomizing core 14 are separated by the movable part 16; when the atomizer 10 is in an operating state, the movable member 16 moves upward, and the liquid storage space 20 communicates with the atomizing core 14 via the movable member 16. Specifically, the user can generate negative pressure at the time of suction, that is, negative pressure in the air outlet direction of the first air passage 121 and the second air passage 131. Under negative pressure, a pressure difference can be generated in the second air passage 131, and under the action of the pressure difference, the movable piece 16 can move in the second air passage 131 and store energy for the energy storage piece 15 in the moving process. Movement of the movable member 16 can place the first air passage 121 in communication with the liquid storage space 20, thereby enabling the atomizing base to enter the first air passage 121, and enabling the atomizing base to be atomized. Under negative pressure, an air flow can be generated in the first air passage 121, thereby giving off the aerosol. After the user stops sucking, the negative pressure is eliminated, and the energy stored in the energy storage member 15 is released, so that the movable member 16 moves, and the communication between the first air passage 121 and the liquid storage space 20 is further limited, so as to avoid the liquid leakage phenomenon. Through the above manner, the movable part 16 in the application can move under the combined action of the suction and energy storage part 15 of the user, so that the liquid storage space 20 and the first air passage 121 can be automatically communicated in the suction process of the user, and the communication between the liquid storage space 20 and the first air passage 121 can be cut off when the user stops the suction, and the convenience of use can be greatly improved without the need of the switch for the user to actively feed the running liquid in a rotating or up-down drawing manner.

Referring to fig. 3 to 6, in some embodiments, specifically, the housing 11 includes a suction nozzle 111, a housing 112, and a base 113 connected in sequence.

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 communicated with the first air channel 121, and the second air inlet channel 1132 is communicated with the second air channel 131. The first air passage 121 and the second air passage 131 can communicate with the outside through the base 113. Optionally, first intake channel 1131 and second intake channel 1132 are open to seal 19 described above. In some embodiments, the second air intake channel 1132 is an annular air channel or through holes spaced in the circumferential direction, which is not specifically limited herein.

In some embodiments, the atomizer 10 further includes a first air flow pipe 12 disposed in the housing 11 and both ends are in communication with the outside, one end of the first air flow pipe 12 being capable of being used for air intake and the other end being capable of being used for air exhaust.

The side wall of the first airflow pipeline 12 is provided with a first through hole 122, the first through hole 122 is used for communicating with the first air passage 121 and the second air passage 131, and the atomization core 14 is arranged corresponding to the first through hole 122. The atomizing substrate can enter the first air passage 121 from the first through hole 122, and since the atomizing core 14 is provided in correspondence with the first through hole 122, the atomizing substrate can enter the atomizing core 14 after passing through the first through hole 122, and thus be atomized by the atomizing core 14.

In some embodiments, the first airflow pipeline 12 is disposed through the suction nozzle 111 and is directly communicated with the outside. The first air flow pipeline 12 can ensure the sealing performance of the first air flow pipeline 12 during suction in a way that the first air flow pipeline 12 is directly communicated with the outside as a complete part through the suction nozzle 111, so that the atomizer 10 does not need to add additional parts to ensure the tightness of the first air flow pipeline 12. In other embodiments, the suction nozzle 111 has an air outlet channel in communication with the outside, and the first air flow pipeline 12 is in communication with the air outlet channel, so that the suction nozzle 111 and the first air flow pipeline 12 have no assembling relationship, so that parts can be manufactured separately from each other, thereby reducing production cost.

In some embodiments, the atomizer 10 further includes a second airflow pipeline 13 disposed in the housing 11 and sleeved outside the first airflow pipeline 12, two ends of the second airflow pipeline 13 are both communicated with the outside, and a second air passage 131 is provided between the second airflow pipeline 13 and the first airflow pipeline 12. One end of the second air flow line 13 can be used for air intake of the second air passage 131, and the other end can be used for air outlet of the second air passage 131.

The second through hole 132 is provided corresponding to the first through hole 122, and the movable member 16 is movable to selectively communicate the first through hole 122 with the second through hole 132, that is, to communicate the first air passage 121 with the liquid storage space 20. With the movable member 16 communicating the first through-hole 122 and the second through-hole 132, the atomizing medium can flow from the liquid storage space 20 into the atomizing core 14 in the first air passage 121 through the first through-hole 122 and the second through-hole 132.

In some embodiments, the second airflow channel 13 is disposed through the suction nozzle 111 and is directly connected to the outside. The second air flow pipeline 13 can ensure the sealing performance of the second air flow pipeline 13 during suction in a way that the second air flow pipeline 13 is directly communicated with the outside as a complete part through the suction nozzle 111, so that the atomizer 10 does not need to add additional parts to ensure the tightness of the second air flow pipeline 13. In other embodiments, the suction nozzle 111 has an air outlet channel in communication with the outside, and the second air flow channel 13 is in communication with the air outlet channel, so that the suction nozzle 111 and the second air flow channel 13 have no assembling relationship, so that the parts can be manufactured separately from each other, thereby reducing the production cost.

In some embodiments, in conjunction with fig. 3 to 6, specifically, the movable member 16 includes a blocking portion 161 and a communicating portion 162 provided with a communicating hole 163. The movable member 16 moves between the first position and the second position in the second air passage 131, and when the movable member 16 is in the first position (for example, as shown in fig. 3 and 4), the blocking portion 161 blocks the first through hole 122 and the second through hole 132, so as to prevent the atomized matrix in the liquid storage space 20 from entering the atomized core 14 of the first air passage 121, thereby realizing liquid core separation. Specifically, when the user is not making a puff, the moveable member 16 is in the first position. When the movable member 16 is in the second position, the communication hole 163 communicates with the first through hole 122 and the second through hole 132 to communicate the liquid storage space 20 with the first air passage 121, so that the atomized substrate can enter the atomizing core 14 in the first air passage 121 through the first through hole 122, the second through hole 132, and the communication hole 163. Specifically, upon user aspiration, a pressure differential is created within the second airway 131, thereby moving the moveable member 16 to the second position (see fig. 5 and 6). Optionally, a limiting member 18 is fixedly disposed in the second air passage 131, and the limiting member 18 is disposed at a preset end point of the moving path of the movable member 16, so as to limit further movement of the movable member 16, so that the movable member 16 can be limited by the limiting member 18 when moving, and thus can be stably disposed at the first position or the second position. In some embodiments, the outer or inner circumference of the moveable member 16 is provided with a sealing ring so that the second air passages 131 on both sides of the moveable member 16 can be spaced so that the user can create a sufficient pressure differential to move the moveable member 16 when inhaling.

In some embodiments, the energy storage member 15 is an elastic member, one end of the elastic member is fixedly disposed in the second air passage 131, and the other end of the elastic member is connected to the movable member 16. The energy storage member 15 may be located at an end of the movable member 16 near the suction nozzle 111, or may be located at an end of the movable member 16 far from the suction nozzle 111, which may depend on the specific structure of the atomizer 10, and is not limited herein. The working process will be exemplarily described taking the energy storage member 15 as a spring and the movable member 16 located at a side close to the suction nozzle 111 as an example. When the user is not sucking, the movable member 16 is in the first position, in which the spring does not exert a pulling force on the movable member 16, and in which the blocking portion 161 of the movable member 16 blocks the first through hole 122 and the second through hole 132. When the user sucks, a negative pressure is generated in the second air passage 131 toward the suction nozzle 111, the movable member 16 moves to the second position by the pressure difference, and the spring compresses to store potential energy. After the movable member 16 is moved to the second position, the first through hole 122 and the second through hole 132 can communicate through the communication hole 163, and the atomizing base can enter the atomizing core 14 of the first air passage 121 to be atomized.

In some embodiments, the second air passage 131 is fixedly provided with a locking member 17, one end of the elastic member abuts against the locking member 17, and the other end is connected with the movable member 16. The locking member 17 is capable of mounting an elastic member in the second air passage 131, and the elastic member may be fixedly connected to the locking member 17 or may abut against the locking member 17, and is not particularly limited. The locking piece 17 is further provided with at least one air hole, the locking piece 17 can prevent air flow in the second air passage 131 while installing the elastic piece, and the air hole can prevent the locking piece 17 from blocking the second air passage 131. Optionally, by setting different numbers of air holes on the locking member 17, the air flow resistance in the second air passage 131 can be adjusted, so that the number of air holes can be set to match the suction force of the user with the elastic force of the elastic member and the resistance of the movement of the movable member 16, so that the user can perform suction conveniently.

The foregoing is only illustrative of the present application and is not to be construed as limiting the scope of the application, and all equivalent structures or equivalent flow modifications which may be made by the teachings of the present application and the accompanying drawings or which may be directly or indirectly employed in other related art are within the scope of the application.
