The filter 16 is inserted into the embedded slide groove, which is convenient for replacing and cleaning the filter 16. After the filter 16 is removed, the zeolite 13 and the activated carbon layer 14 in the arc cover 8 can be taken out.

[0018] One end of the paint mist duct 4 passes through the base 1 and is connected to an external air pump, and the other end of the paint mist duct 4 is built into the mechanical arm 2 and is connected to several nozzles 5 at the bottom of the nozzle fixing plate 6 through branch ducts built into the nozzle fixing plate 6, so that the paint mist can be sprayed out from multiple nozzles 5 at high pressure along the paint mist duct 4 under the action of the air pump to carry out painting operations.

[0019] Working principle:
