The motor 204 is fixedly connected to a guide ring 205 on the side away from the gear 202. The inner wall of the guide ring 205 is slidably connected to a sliding rod 207. One end of the arc surface of the sliding rod 207 is fixedly connected to a plurality of fixed rods 208. The ends of the fixed rods 208 away from the arc surface of the sliding rod 207 are fixedly connected to the pipeline body 4.

The cleaning plate 209 is slidably connected to the inner wall of the pipe body 4. The negative pressure device 1 for the formation of lithium batteries is a device specially designed to handle the gas emissions of lithium batteries during the formation process and maintain a negative pressure state. The pipe body 4 is a pipeline system specially used to handle and discharge the gas generated in the formation stage. When the pipe body 4 is used for a long time, the gas residue generated in the formation process will accumulate inside the pipe. A large amount of residue accumulation will affect the flowability of the pipe body 4, causing the pipe body 4 to fail to work normally. At this time, it can be passed through The adjusting device 2 is used to clean the inside of the pipe body 4, thereby preventing residues from accumulating in the pipe body 4 through cleaning, thereby improving the use effect of the pipe body 4 through cleaning.

When the rotating rod 211 is rotated on the cleaning plate 209, the anti-slip grooves 212 on the rotating rod 211 can increase the friction between the rotating rod 211 and the user's hand, thereby improving the efficiency of rotating the rotating rod 211 on the cleaning plate 209 through the anti-slip grooves 212. A handle 203 is fixedly connected to one side of the cleaning plate 209. When the cleaning plate needs to be installed or removed, the handle 203 installed on the cleaning plate can facilitate personnel to take the cleaning plate 209, thereby improving the efficiency and speed of replacing or installing the cleaning plate through the handle 203;

[0034] In the embodiments of the present invention, please refer to Figure 5The auxiliary device 3 includes a fixing ring 31, which is fixedly connected to the arc surface of the motor 204. One end of the arc surface of the fixing ring 31 is fixedly connected to an arc rod 32, and one end of the arc surface of the arc rod 32 is fixedly connected to an electric push rod 33. The output end of the electric push rod 33 is fixedly connected to a connecting block 34.

The auxiliary device 3 can improve the fixing effect of the cleaning plate 209 when the cleaning plate 209 is not in use, thereby preventing the cleaning plate 209 from shaking in the pipeline body 4, and further To improve the practicality of the cleaning plate 209, a contact pad 35 is fixedly connected to one side of the inner wall of the connecting block 34. The side of the contact pad 35 away from the connecting block 34 is provided with anti-slip grooves. When the connecting block 34 contacts the sliding rod 207, the contact pad 35 installed on the connecting block 34 can increase the contact friction between the connecting block 34 and the sliding rod 207, thereby improving the contact stability between the connecting block 34 and the sliding rod 207. The arc rod 32 is a titanium alloy rod. The arc rod 32 made of titanium alloy has a relatively hard rod surface, which also makes the arc rod 32 made of titanium alloy less likely to deform after long-term use, and has a longer service life.

[0035] The working principle of a cleaning device for a lithium battery-generating negative pressure pipeline provided by the present invention is as follows: starting the motor 204, the movement of the motor 204 will drive the gear 202 to rotate through the output end, and the rotation of the gear 202 will engage with the gear ring 201. At this time, the motor 204 will slide along the direction of the sliding rod 207 through the guide ring 205. Because the sliding rod 207 is fixed to the pipeline body 4 through the fixed rod 208, the motor 204 will slide along the sliding rod 207 on the arc surface of the pipeline body 4 under the action of the guide ring 205. A connecting rod 206 and a cleaning plate 209 are installed on the guide ring 205, so that the inner wall of the pipeline body 4 can be cleaned through the cleaning plate 209 on the connecting rod 206.

[0036] When the cleaning plate 209 is not in use, the electric push rod 33 installed on the arc rod 32 is started. The movement of the electric push rod 33 will drive the connecting block 34 to move through the output end. The movement of the connecting block 34 will come into contact with the sliding rod 207, thereby fixing the position of the cleaning plate 209 through the contact between the connecting block 34 and the sliding rod 207.
