At the same time, since the self-cleaning mechanism 300 is provided, the dust removal mechanism 200 is cleaned by using the set self-cleaning mechanism 300, which also enables the present invention to avoid the defect of dust pollution or blockage of the dust removal mechanism 200 when in use, thereby ensuring the safe use of the equipment.

[0055] In some specific embodiments, the self-cleaning mechanism 300 includes a sealing component 310 and a self-cleaning component 320. The sealing component 310 is arranged close to the air outlet 130. The sealing component 310 can open or close the air outlet 130. The self-cleaning component 320 is installed on the periphery of the dust removal mechanism 200. The self-cleaning component 320 can clean the dust removal mechanism 200 when the sealing component 310 closes the air outlet 130.

The sealing ring 312 is folded inward on both sides along the thickness direction of the sealing piece 311 to form a folded ring 315 that fits on the sealing piece on the corresponding side, and the sealing ring 312 is formed with flexible convex rings 316 distributed at intervals along the thickness direction of the sealing piece 311.

[0066] In this embodiment, the sealing ring 312 is folded on both sides along the thickness direction of the sealing sheet to form a folded ring 315, so that during use, the present invention can avoid scratching and damage to the sealing ring 312 during rotation, thereby improving the service life of the sealing ring 312. Of course, in order to make the present invention have a better sealing effect, a flexible convex ring 316 is also provided on the outer periphery of the sealing ring 312 during specific use, so that the sealing ring 312 can effectively seal the air outlet 130, thereby improving the sealing effect.

The air source purified by the dust removal mechanism 200 can flow from the air collecting cylinder 321 to the first air outlet end through the first air inlet end.

[0071] The fan 322 is installed in the air collecting tube 321 to suck the natural wind of the dust removal cavity 140 into the air collecting tube 321 from the first air inlet end;

[0072] The cleaning module 323 is installed at the first air outlet end. The multi-joint robotic arm can drive the air collecting tube 321 to drive the cleaning module 323 to move to any position on the outer surface of the dust removal mechanism 200 and stop. When the cleaning module 323 stops, the wind source sucked in by the fan 322 is blown out through the first air outlet end to drive the cleaning module 323 to clean the dust removal mechanism 200.

[0073] In the present embodiment, an air collecting tube 321, a fan 322 and a cleaning module 323 are provided. When in use, the air in the dust removal cavity 140 is sucked into the air collecting tube 321 by utilizing the air collecting tube 321 and the fan 322 installed in the air collecting tube 321 so that the air entering the air collecting tube 321 can drive the cleaning module 323, so that the cleaning module 323 cleans the dust removal mechanism 200. When in use, the present invention can directly utilize the fan 322 to allow the air entering the dust removal cavity 140 to simultaneously have the function of cleaning the dust removal mechanism 200.

[0076] In some preferred embodiments, the cleaning module 323 includes:

[0077] The air collecting pipe 323a has two ends, namely, a second air inlet end and a second air outlet end. The second air inlet end is sealed and connected to the first air outlet end. The air collecting pipe 323a has an air collecting passage which is gradually narrowed from the second air inlet end toward the second air outlet end.

[0078] A driving impeller 323d is rotatably mounted on the second air outlet end, and the impeller passes through the air collecting pipe 323a from the side wall of the air collecting pipe 323a through a connecting shaft 323e to form a mounting end 323f, and the connecting shaft 323e is rotatably matched with the pipe wall of the air collecting pipe 323a;
