DETAILED DESCRIPTION

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0025] The utility model embodiment provides a piston ventilation module, such as Figures 1 to 5 As shown, it includes a piston assembly 10, a breather 20 and a valve 30; the piston assembly 10 includes a piston arm 110 and a piston tube 120 that are sealed and connected, and the piston arm 110 can perform telescopic movement in the piston tube 120; the breather 20 is arranged on the side of the piston tube 120 away from the piston arm 110, and the breather 20 is formed with an air inlet 201 and an air outlet 202 that are independent of each other; the valve 30 is arranged between the piston tube 120 and the breather 20, and the valve 30 includes a valve body and a first one-way valve plate 310 and a second one-way valve plate 320 that are independently arranged on the valve body; the first one-way valve plate 310 and the second one-way valve plate 320 are independently arranged on the valve body; A one-way valve plate 310 and a second one-way valve plate 320 are movably arranged on the valve body; the first one-way valve plate 310 is arranged between the air inlet hole 201 and the piston tube 120, and is used to control the one-way conduction from the air inlet hole 201 to the piston tube 120, and the second one-way valve plate 320 is arranged between the air outlet hole 202 and the piston tube 120, and is used to control the one-way conduction from the piston tube 120 to the air outlet hole 202; wherein, when the piston arm 110 performs telescopic movement in the piston tube 120, external air enters the piston tube 120 along the air inlet hole 201 and is compressed to obtain compressed air, and the compressed air is output along the air outlet hole 202.

[0026] In the piston ventilation device of this embodiment, when the piston arm 110 moves telescopically within the piston tube 120, specifically, when the piston arm 110 retracts from within the piston tube 120, external air enters the ventilation member 20 along the intake hole 201. Under the impact of the air flow, the first one-way valve piece 310 moves on the valve body and is in an open state. The external air enters the piston tube 120 along the intake hole 201. When the piston arm 110 extends into the piston tube 120, the air within the piston tube 120 is compressed to obtain compressed air. The air flow of the compressed air impacts the second one-way valve piece 320 to move on the valve body, so that the second one-way valve piece 320 is in an open state. The compressed air is output along the air outlet hole 202 of the ventilation member 20 and is delivered to the atomizing tube of the atomizer. The piston ventilation module of the present utility model cleverly utilizes the change in air flow during the operation of the piston assembly 10 to achieve the opening and closing of the valve 30, without the need to rely on a spring or other auxiliary devices to control the opening and closing of the valve 30, simplifies the structure of the piston ventilation module, and facilitates the use and popularization of the atomizer.

[0027] As a preferred solution of this embodiment, referring to Figure 4 and Figure 5 , the ventilation member 20 is provided with an air tube 203 and an air cavity 204. The air tube 203 is communicated with the intake hole 201, and the air cavity 204 is communicated with the air outlet hole 202. The piston tube 120 is provided with a receiving cavity 1201, a first air port 1202 and a second air port 1204 which are respectively communicated with the receiving cavity 1201. The first one-way valve piece 310 is arranged between the first air port 1202 and the air tube 203 and can cover the air tube 203 or move within the first air port 1202. When the first one-way valve piece 310 covers the air tube 203, the first air port 1202 and the air tube 203 are cut off. When the first one-way valve piece 310 moves within the first air port 1202, the first air port 1202 and the air tube 203 are communicated. The second one-way valve piece 320 is arranged between the second air port 1204 and the air cavity 204 and can cover the second air port 1204 or move within the air cavity 204. When the second one-way valve piece 320 covers the second air port 1204, the second air port 1204 and the air cavity 204 are cut off. When the second one-way valve piece 320 moves within the air cavity 204, the second air port 1204 and the air cavity 204 are communicated. The piston arm 110 is hermetically connected to the receiving cavity 1201.

[0028] In this embodiment, a structural example of the ventilation member 20 and the piston tube 120 is given. Specifically, external air enters the ventilation member 20 from the air inlet hole 201 and flows in the first ventilation member 20 along the air tube 203. Under the action of the air flow, the gas output from the air tube 203 impacts the first one-way valve piece 310, causing the first one-way valve piece 310 to approach the first air port 1202 and move within the first air port 1202. At this time, the first one-way valve piece 310 is in an open state and controls the opening of the first air port 1202. The first air port 1202 is communicated with the air tube 203. When the compressed gas in the piston tube 120 passes through the first air port 1202, under the action of the air flow, the first one-way valve piece 310 adheres to the air tube 203 and covers the air tube 203. At this time, the first one-way valve piece 310 is in a closed state and cuts off the first air port 1202 and the air tube 203, achieving the purpose of unidirectional conduction from the air inlet hole 201 to the piston tube 120.

[0029] When the compressed air is output along the second air port 1204, under the action of the air flow, the gas output from the second air port 1204 impacts the second one-way valve piece 320, causing the second one-way valve piece 320 to approach the air cavity 204 and move within the air cavity 204. At this time, the second one-way valve piece 320 is in an open state and controls the opening of the second air port 1204. The second air port 1204 is communicated with the air cavity 204. The compressed air enters the ventilation member 20 along the air cavity 204 and is output along the air outlet hole 202. When the external air in the ventilation member 20 passes through the second air port 1204, under the action of the air flow, the second one-way valve piece 320 adheres to the second air port 1204 and covers the second air port 1204. At this time, the second one-way valve piece 320 is in a closed state and cuts off the second air port 1204 and the air cavity 204, achieving the purpose of unidirectional conduction from the piston tube 120 to the air outlet hole 202.

[0030] As a preferred solution of this embodiment, referring to Figure 4 and Figure 5 , a first limiting member is arranged in the first air port 1202, and a first limiting inclined surface 1211 is formed on the first limiting member. When the first one-way valve piece 310 moves into the first air port 1202, the first one-way valve piece 310 abuts against the first limiting inclined surface 1211; a second limiting member 122 is arranged in the air cavity 204, and a second limiting inclined surface 1221 is formed on the second limiting member 122. When the second one-way valve piece 320 moves into the air cavity 204, the second one-way valve piece 320 abuts against the second limiting inclined surface 1221.

[0031] Among them, in order to prevent the first one-way valve piece 310 and the second one-way valve piece 320 from having too large an opening degree during the opening process, resulting in deformation of the first one-way valve piece 310 and the second one-way valve piece 320, which affects the airtightness when the first one-way valve piece 310 adheres to the air pipe 203 and the second one-way valve piece 320 adheres to the second air port 1204. Specifically, a first limiting member is provided in the first air port 1202, and a first limiting inclined surface 1211 is formed on the first limiting member. When the first one-way valve piece 310 is impacted by the air flow and moves into the first air port 1202, the first one-way valve piece 310 abuts against the first limiting inclined surface 1211 to form a limit on the movement of the first one-way valve piece 310, preventing the first one-way valve piece 310 from being excessively deformed; a second limiting member 122 is provided in the air cavity 204, and the second limiting member 122 has a second limiting inclined surface 1221 formed thereon. When the second one-way valve piece 320 is impacted by the air flow and moves into the air cavity 204, the second one-way valve piece 320 abuts against the second limiting inclined surface 1221 to form a limit on the movement of the second one-way valve piece 320, preventing the second one-way valve piece 320 from being excessively deformed.
