The suction cup 140 is communicated with a fresh air module 180 of the air conditioner through a pipeline 151. In the cleaning mode, the fresh air module 180 is started to extract air in the suction cup 140, so that negative pressure is generated in the suction cup 140, and the suction hole of the suction cup 140 generates strong suction force due to the large pressure difference between the negative pressure and the atmospheric pressure, so that dust is sucked into the suction cup 140.

Alternatively, the suction hole on the suction cup 140 may be a plurality of small circular holes, or may be a strip-shaped narrow slit. When the suction holes are a plurality of small circular holes, the plurality of small circular holes are arranged in one or more rows along the length direction of the air duct 110. When the suction holes are strip-shaped narrow slits, the opening direction of the narrow slits is the same as the length direction of the air duct 110, and the number of the narrow slits can be one row or multiple rows. The smaller the suction hole, the greater the suction force generated at the suction hole by the negative pressure inside the suction cup 140, and the cleaner the dust is sucked.

Alternatively, the suction holes of the suction cup 140 may be formed at the left and right sides of the suction cup 140 near the air duct 110.
