The air flow carries the dust collected by the rolling brush assembly into the dust collection box 20 in the flowing process, and the dust is retained in the dust collection cavity 21 under the action of the filter element 252 in the dust collection box 20, and the cleaning air flow flows to the outside again from the air duct.

With continued reference to fig. 3, the dust collecting box 20 includes a box body 24 and a filter element 25, the air inlet 22 and the dust collecting cavity 21 are both disposed on the box body 24, the filter element 25 includes a mounting member 251 and a filter element 252, the filter element 252 is mounted on the mounting member 251, the mounting member 251 has a locking position capable of locking with the box body 24 and an unlocking position capable of unlocking relative to the box body 24, and when the mounting member 251 is in the locking position, the filter element 252 is located on a flow path of the air flow flowing from the dust collecting cavity 21 to the air outlet 23.

Here, when a pressing force is applied to the fitting 251 in the first direction, the fitting 251 can be switched from one of the lock position and the unlock position to the other. That is, when the fitting 251 needs to be switched from the locked position to the unlocked position, the switching can be completed only by pressing the fitting 251 in the first direction; when it is desired to switch from the unlocked to the locked position, the switch can be completed by simply pressing the fitting 251 again in the first direction.

Through the above-mentioned setting, when needing to clear up filtering piece 252, only need press assembly part 251 on the first direction, can dismantle filtering component 25 from box body 24 and clear up filtering piece 252, after the clearance is accomplished, only need press assembly part 251 once more on the first direction, can assemble filtering component 25 on box body 24, filtering component 25 easy dismounting.
