When the fan assembly of the air conditioner is running, the air enters the housing 3 from the air inlet 31 of the air conditioner to form an air flow, and the air flow drives the wind wheel 104 when it passes through the air conditioner. The wind wheel 104 rotates, and the wind wheel 104 drives the closed filter screen 101 to rotate circularly around the first support shaft 103 and the second support shaft 102 through the transmission device. The foreign matter, the air flow enters the dust collecting box body 201 from the air inlet 2013 of the dust collecting box body 201, and the foreign matter brushed off by the brush 202 is driven by the air flow to flow through the dust filter module 203. The air outlet 2012 flows out.

Specifically, when the fan assembly of the air conditioner is in operation, air enters the casing 3 from the air inlet 31 of the air conditioner to form an air flow, and when the air flow passes through the wind wheel 104, it drives the wind wheel 104 to rotate, and the wind wheel 104 drives the second transmission gear through the first transmission gear Rotate, the second transmission gear drives the third transmission gear 109 to rotate, the third transmission gear 109 drives the closed transmission belt 108 to rotate, and the closed transmission belt 108 drives the closed filter screen 101 to rotate around the first support shaft 103 and the second support shaft 102 , the brush in the dust collection box body 201 removes foreign matter on the closed filter screen 101, part of the air flow enters the dust collection box body 201 from the air inlet 2013, and the foreign matter removed by the brush is driven by the air flow to flow through the dust filter module 203, and the dust filter module After 203 absorbs the foreign matter, the airflow flows out from the air outlet 2012 of the dust collecting box body.
