[0028] The servo motor 223 drives the connecting rod 224 and the gear 225 to rotate, and the gear 225 drives the filter screen plate 221 to descend by meshing with the rack 222. When the connecting rod 224 rotates, the pulley 2201 and the transmission belt 2202 are driven to rotate the rotating plate 228, so that the linkage sleeve rod 229 drives the linkage rod 227 and the baffle 226 to slide, thereby reducing the air intake of the dust cover 212.
