Under the action of centrifugal force, the dust particles in the air are thrown to the side wall of the separation chamber 23 and fall along the side wall of the separation chamber 23, and the air continues to perform centrifugal motion and is discharged from the filter assembly through the air outlet pipe. In this way, through the filtering of dust particles in the air by the separation chamber 23, the filtering of the air passing therethrough by the filter assembly is realized.

Optionally, the enclosure plate 21 is provided with an air inlet 24 , and the air inlet 24 communicates with the air inlet passage 30 . In this way, the air enters the separation chamber 23 from the air inlet passage 30 through the air inlet 24, and performs centrifugal motion in the separation chamber 23 to filter out the dust particles in the air, thereby realizing the filtering of the air.

Here, the shape of the air inlet 24 is not specifically limited, and the air inlet 24 may be a square shape, a circular shape, or an irregular shape entering along the tangential direction of the enclosure plate 21 .
