[0029] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Now, in conjunction with the drawings, the preferred embodiments of the present utility model will be described in detail.

[0030] The embodiment of the present utility model provides a compression module, as Figures 1 to 8 shown, including a driving assembly 10, a piston mechanism 20 and a snap ring 30. The driving assembly 10 includes a driver 110 and an eccentric shaft 120 arranged on the driver 110. The eccentric shaft 120 includes a first shaft body 121, a card slot 122 and a second shaft body 123 arranged in sequence. The piston mechanism 20 includes a first piston assembly 210 and a second piston assembly 220.

The second piston assembly 220 includes a second piston arm 221 and a second piston tube 222 which are hermetically connected. The first piston arm 211 is sleeved on the first shaft body 121, the second piston arm 221 is sleeved on the second shaft body 123, and the first piston arm 211 sleeve and the second piston arm 221 extend in opposite directions along the eccentric shaft 120. The snap ring 30 is arranged on the card slot 122 and is detachably connected to the eccentric shaft 120.

[0031] The drive 110 can drive the eccentric shaft 120 to rotate on the drive 110. The eccentric shaft 120 includes a first shaft body 121, a card slot 122, and a second shaft body 123 arranged in sequence. The first piston arm 211 is arranged on the first shaft body 121, the second piston arm 221 is arranged on the second shaft body 123, and a snap ring 30 is arranged on the card slot 122. The snap ring 30 can isolate the first piston arm 211 and the second piston arm 221 on the eccentric shaft 120, so that the first piston arm 211 and the second piston arm 221 are independent of each other on the eccentric shaft 120, avoiding interference with each other during their movement. At the same time, the snap ring 30 is detachably connected to the eccentric shaft 120, facilitating the assembly of the piston mechanism 20 and the drive assembly 10, and will not interfere with the arrangement of the first piston arm 211 and the second piston arm 221 on the eccentric shaft 120. During actual installation, the second piston arm 221, the snap ring 30, and the first piston arm 211 are sequentially sleeved on the positions corresponding to the eccentric shaft 120, and the assembly of the piston mechanism 20 and the drive assembly 10 can be quickly realized. Similarly, it is also convenient for the maintenance of the compression module. The compression module of this embodiment is convenient for assembly and maintenance, and the operation is simple and easy.

[0032] The working process of the above compression module is as follows:

[0033] The drive 110 drives the eccentric shaft 120 to rotate. The first piston arm 211 and the second piston arm 221 extend in opposite directions on the eccentric shaft 120, and the eccentric shaft 120 can drive the first piston arm 211 to perform telescopic movement in the first piston tube 212 and the second piston arm 221 to perform telescopic movement in the second piston tube 222, thereby achieving the purpose of generating the first compressed gas and the second compressed gas.

[0034] As a preferred solution of this embodiment, referring to Figure 4 , a bushing 130 is arranged on the side of the eccentric shaft 120 close to the drive 110. The axis of the eccentric shaft 120 is separated from the axis of the bushing 130, and the bushing 130 is sleeved on the drive shaft 111 of the drive 110.

[0035] Among them, the bushing 130 is arranged to be connected to the drive shaft 111 of the drive 110, so that the eccentric shaft 120 is stably arranged on the drive shaft 111, and the connection stability between the eccentric shaft 120 and the drive 110 is improved. The axis of the eccentric shaft 120 is separated from the axis of the bushing 130, so that the position of the eccentric shaft 120 can ensure that after the first piston arm 211 and the second piston arm 221 are arranged on the eccentric shaft 120, the eccentric shaft 120 can drive the first piston arm 211 and the second piston arm 221 to perform telescopic movement respectively. The above first piston arm 211 and second piston arm 221 are both rotatably arranged on the eccentric shaft 120.

[0036] As a preferred solution of this embodiment, referring toFigure 4 A mounting boss 124 is disposed at one end of the second shaft body 123 close to the shaft sleeve 130 , and the second piston arm 221 is disposed on the mounting boss 124 .

[0037] The installation of the mounting boss 124 provides a stable installation environment for the second piston arm 221 on the second shaft body 123, and at the same time, it can prevent the second piston arm 221 from falling on the second shaft body 123 due to gravity and other reasons, thereby playing a limiting role. The mounting boss 124 is an annular structure, which ensures the contact area between the second piston arm 221 and the mounting boss 124, and provides stable support.

[0038] As a preferred solution of this embodiment, refer to Figure 5 A first notch 301 is formed on the outer circumference of the snap ring 30 along its radial direction, and the first notch 301 is connected to the inner ring of the snap ring 30 .

[0039] Among them, when the retaining ring 30 is set to be detachably connected with the eccentric shaft 120, it is necessary to cooperate with the slot 122 through the first notch 301, and the retaining ring 30 is clamped on the slot 122 along the first notch 301. During the maintenance process, when the retaining ring 30 needs to be removed, the retaining ring 30 and the slot 122 are also separated along the first notch 301.

[0040] The size of the first notch 301 can be set according to the diameters of the slot 122 and the eccentric shaft 120 in actual application, and it is necessary to ensure that the snap ring 30 can be firmly fixed on the slot 122, which is not specifically limited here.

[0041] As a preferred solution of this embodiment, refer to Figure 5 A second notch 302 is formed on the inner ring of the snap ring 30 along its radial direction.

[0042] During the actual installation process of the snap ring 30, the snap ring 30 will be deformed when matched with the slot 122. The second notch 302 is provided to facilitate the deformation of the snap ring 30 itself so that the first notch 301 is slightly opened. After the snap ring 30 and the slot 122 are fully matched, the snap ring 30 returns to its initial state. The provision of the second notch 302 reduces the difficulty of installation and removal of the snap ring 30, and can quickly realize the detachable connection between the snap ring 30 and the eccentric shaft 120, thereby further improving the practicality and convenience of installation.

[0043] As a preferred solution of this embodiment, refer to Figures 1 to 3 , Figure 7 as well as Figure 8A first piston disc 2111 is provided at one end of the first piston arm 211, and the first piston disc 2111 is sealed and connected to the first piston tube 212; a second piston disc 2211 is provided at one end of the second piston arm 221, and the second piston disc 2211 is sealed and connected to the second piston tube 222; a first threaded hole 2112 is formed at one end of the first piston arm 211, and a first clamping disc 2113 is provided on the side of the first piston disc 2111 away from the first piston arm 211, and the first clamping disc 2113 is provided on the side of the first piston disc 2111 away from the first piston arm 211. A first fastener 2114 is provided, and the first fastener 2114 passes through the first clamping plate 2113 and is threadedly connected to the first threaded hole 2112; a second threaded hole 2212 is formed at one end of the second piston arm 221, and a second clamping plate 2213 is provided on the side of the second piston plate 2211 away from the second piston arm 221, and a second fastener 2214 is provided on the second clamping plate 2213, and the second fastener 2214 passes through the second clamping plate 2213 and is threadedly connected to the second threaded hole 2212.

[0044] In this embodiment, a structural matching example of the first piston arm 211 and the first piston tube 212 and the second piston arm 221 and the second piston tube 222 is provided. Specifically, a first piston disc 2111 is provided at one end of the first piston arm 211 to achieve the purpose of sealing connection between the first piston arm 211 and the first piston tube 212, ensure the airtight connection between the first piston disc 2111 and the first piston tube 212, and improve the smoothness of the first piston disc 2111 in the first piston tube 212 when performing telescopic movement. A second piston disc 2211 is provided at one end of the second piston arm 221 to achieve the purpose of sealing connection between the second piston disc 2211 and the second piston tube 222, ensure the airtight connection between the second piston disc 2211 and the second piston tube 222, and improve the smoothness of the first piston disc 2111 in the first piston tube 212 when performing telescopic movement. In this way, the purpose of alternately generating compressed gas by the first piston assembly 210 and the second piston assembly 220 is achieved.

[0045] In the actual application process of this embodiment, refer to Figure 7 and Figure 8 The first piston tube 212 is provided with a first accommodating chamber 21201, a first air port 21202 and a second air port 21203 respectively connected to the first accommodating chamber 21201; the second piston tube 222 is provided with a second accommodating chamber 22201, a third air port 22202 and a fourth air port 22203 respectively connected to the second accommodating chamber 22201; the first piston disc 2111 is arranged in the first accommodating chamber 21201 and is sealedly connected to the first piston tube 212, and the second piston disc 2211 is arranged in the second accommodating chamber 22201 and is sealedly connected to the second piston tube 222.

[0046] 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 output the first compressed air, and the first compressed air is output along the second air port 21203. 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 sucked into the second piston tube 222 along the third air port 22202. As the eccentric shaft 120 rotates, the first piston arm 211 is pushed to retract from the first piston tube 212, and the external air is sucked into the first piston tube 212 along the first air port 21202. 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 output the second compressed air, and the second compressed air is output along the fourth air port 22203. The above process achieves the purpose of the first piston assembly 210 and the second piston assembly 220 alternately generating the first compressed air and the second compressed air. The first compressed air and the second compressed air are delivered to the atomization pipe.

[0047] The first piston disc 2111 and the second piston disc 2211 may be made of sealing material.
