The ventilation holes 413 connect the ventilation opening 411 with the ventilation slot 412. The internal structure of the ventilation plate 41 is simple and has good connectivity, which can ensure the speed at which the ventilation plate 41 processes dust.

[0034] The ventilation plate 41 is provided with a plurality of ventilation holes 413 , which are distributed along the circumferential direction of the ventilation plate 41 , and can further improve the connectivity between the ventilation openings 411 and the ventilation slots 412 , and ensure that dust can smoothly enter the ventilation slots 412 from the ventilation openings 411 .

[0035] The ventilation plate 41 is provided with a connecting pipe 414 outside, and the connecting pipe 414 is connected to the ventilation port 411; the ventilation pipe 42 is sleeved on the connecting pipe 414.
