The area of ​​the cabin is usually large. In order to meet the comfort level, it is necessary to ensure that the air supply of the air conditioner is large, the noise is low and the temperature difference is uniform.

[0003] In the prior art, an air distributor with a silencer box is usually arranged on the cabin ceiling, and air is supplied to the cabin through the air outlet of the air distributor. A filter is usually installed in the air duct of the air distributor to filter pollutants such as dust, so that the gas entering the cabin is fresher. However, after the air duct used for air supply has been used for a long time, a lot of dust will accumulate on the filter installed inside the air duct. If the dust accumulated on the filter is not promptly and effectively handled, the mesh will be clogged, resulting in the air supply effect being affected.
