[0031] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Now, in conjunction with the accompanying drawings, detailed descriptions of the preferred embodiments of the present invention are provided.

[0032] An embodiment of the present invention provides a compression module, as Figures 1 to 10As shown, it includes a drive assembly, a piston mechanism 20 and a ventilation assembly. The drive assembly includes a driver 110 and an eccentric shaft 120 provided on the driver 110. The piston mechanism 20 includes a first piston assembly 210 and a second piston assembly 220. The first piston assembly 210 includes a first piston arm 211 and a first piston tube 212 which are hermetically connected. The second piston assembly 220 includes a second piston arm 221 and a second piston tube 222 which are hermetically connected. Both the first piston arm 211 and the second piston arm 221 are sleeved on the eccentric shaft 120 and extend in opposite directions along the eccentric shaft 120 respectively. The ventilation assembly includes a first ventilation member 310 and a second ventilation member 320. The first ventilation member 310 is provided on the first piston tube 212, and the second ventilation member 320 is provided on the second piston tube 222. A mutually independent first intake hole 3101 and a first outlet hole 3102 are formed on the first ventilation member 310, and a mutually independent second intake hole 3201 and a second outlet hole 3202 are formed on the second ventilation member 320. The driver 110 is used to drive the eccentric shaft 120 to move. The eccentric shaft 120 drives the first piston arm 211 to perform telescopic movement in the first piston tube 212, so that air can enter the first piston tube 212 along the first intake hole 3101 to be compressed to obtain first compressed air, and the first compressed air can be output along the first outlet hole 3102. At the same time, the eccentric shaft 120 also drives the second piston arm 221 to perform telescopic movement in the second piston tube 222, so that air can enter the second piston tube 222 along the second intake hole 3201 to be compressed to obtain second compressed air, and the first compressed air can be output along the second outlet hole 3202.

[0033] In the compression module of this embodiment, the setting of the driving component provides a power source for the movement of the piston mechanism 20. When the driver 110 of the driving component works, it can drive the eccentric shaft 120 to rotate on the driver 110. The first piston arm 211 and the second piston arm 221 are both sleeved on the eccentric shaft 120, and the first piston arm 211 and the second piston arm 221 extend in opposite directions along the eccentric shaft 120, so as to achieve the purpose of the first piston arm 211 performing telescopic movement in the first piston tube 212 and the second piston arm 221 performing telescopic movement in the second piston tube 222. Specifically, when the eccentric shaft 120 pushes the first piston arm 211 into the first piston tube 212, the air in the first piston tube 212 is compressed to obtain the first compressed air, and the first compressed air is output along the first air outlet 3102. At the same time, the eccentric shaft 120 pushes the second piston arm 221 to retract from the second piston tube 222, and the external air is inhaled into the second piston tube 222 along the second air inlet 3201. As the eccentric shaft 120 rotates, it pushes the first piston arm 211 to retract from the first piston tube 212, and the external air is inhaled into the first piston tube 212 along the first air inlet 3101. At the same time, the eccentric shaft 120 pushes the second piston arm 221 into the second piston tube 222, and the air in the second piston tube 222 is compressed to obtain the second compressed air, and the second compressed air is output along the second air outlet 3202. In the compression module of the present utility model, only through the cooperative setting of a driver 110 and an eccentric shaft 120, the purpose of driving the first piston assembly 210 and the second piston assembly 220 to alternately generate the first compressed air and the second compressed air can be achieved, which simplifies the structural composition of the compression module, thereby reducing the volume of the compression module, realizing the miniaturized design of the atomizer, and facilitating the popularization of the atomizer.

[0034] In the actual application process, the first compressed air and the second compressed air are delivered to the atomizing tube.

[0035] The above-mentioned eccentric shaft 120 is respectively rotatably connected to the first piston arm 211 and the second piston arm 221 to achieve the purpose of the eccentric shaft 120 driving the first piston arm 211 and the second piston arm 221 to perform telescopic movement. The axis of the eccentric shaft 120 is separated from the axis of the drive shaft of the driver 110, so as to achieve the purpose that the axis of the eccentric shaft 120 and the axis of the drive shaft of the driver 110 are not collinear.

Specifically, air enters the first noise reducer 410 along the first air hole 4101. A first noise reduction channel is formed between the first air hole 4101 and the second air hole 4102.

The first compressed air enters the fifth air hole 4202 along the first air outlet hole 3102. A third noise reduction channel is formed between the fourth air hole 4201 and the fifth air hole 4202. After the first compressed air is reduced in noise through the third noise reduction channel, it is output from the fourth air hole 4201. The second compressed air enters the sixth air hole 4203 along the second air outlet hole 3202. A fourth noise reduction channel is formed between the fourth air hole 4201 and the sixth air hole 4203.

At this time, the second one-way valve piece 520 is in a closed state and cuts off the second air port 2123 and the first air cavity 3104, achieving the purpose of unidirectional conduction from the first piston pipe 212 to the first air outlet hole 3102.

[0043] External air enters the second venting member 320 through the second air inlet 3201 and flows within the second venting member 320 along the second air pipe 3203. Under the action of the air flow, the gas output from the second air pipe 3203 impacts the third one-way valve disc 610, causing the third one-way valve disc 610 to approach the third air port 2222 and move within the third air port 2222. At this time, the third one-way valve disc 610 is in an open state and controls the opening of the third air port 2222. The third air port 2222 is in communication with the second air pipe 3203. When the second compressed gas in the second piston pipe 222 passes through the third air port 2222, under the action of the air flow, the third one-way valve disc 610 adheres to the second air pipe 3203 and covers the second air pipe 3203. At this time, the third one-way valve disc 610 is in a closed state and cuts off the third air port 2222 and the second air pipe 3203, achieving the purpose of one-way conduction from the second air inlet to the second piston pipe 222.

[0044] When the second compressed air is output along the fourth air port 2223, under the action of the air flow, the gas output from the fourth air port 2223 impacts the fourth one-way valve disc 620, causing the fourth one-way valve disc 620 to approach the second air cavity 3204 and move within the second air cavity 3204. At this time, the second one-way valve disc 520 is in an open state and controls the opening of the fourth air port 2223. The fourth air port 2223 is in communication with the second air cavity 3204. The second compressed air enters the second venting member 320 along the second air cavity 3204 and is output along the second air outlet 3202.
