In this embodiment, the shape of the shielding portion 543 is the same as the shape of the front wall of the dirt collecting chamber 511, and the width δ of the gap 580 is 1mm to 10mm. Specifically, the cross-sectional shapes of the blocking portion 543 and the front wall of the dirt collecting chamber 511 along the direction perpendicular to the height direction are both substantially arc-shaped, and the width δ of the gap 580 is preferably set to 8mm.

The minimum transverse distance between the blocking part 543 and the vent 521 is S, and S is more than or equal to 5mm. The minimum transverse distance S between the blocking portion 543 and the vent 521 is reasonably set, so that dirt is prevented from splashing into the vent 521 beyond the blocking portion 543. In this embodiment, the minimum lateral distance S between the shielding portion 543 and the vent 521 refers to the lateral distance between the rear wall of the shielding portion 543 and the front inner wall of the vent 521, and S is preferably set to 6mm.
