In the related art, referring to fig. 21 and 22, a filter unit 83 of a clothes treatment system includes a mounting bracket 1, a first seal ring 4, a second seal ring 5 and a filter screen assembly 2 located in the mounting bracket 1, at an air outlet 21 of the filter screen assembly 2, the filter screen assembly 2 of the filter unit 83 is sealed with the mounting bracket 1 by end faces of the first seal ring 4 and the second seal ring 5 arranged along an axial direction of the filter screen assembly 2, the first seal ring 4 is connected with the filter screen assembly 2, the second seal ring 5 is connected with the mounting bracket 1, a sealing effect between the first seal ring 4 and the second seal ring 5 is greatly influenced by a tightness degree between the filter screen assembly 2 and the mounting bracket 1, the filter screen assembly 2 is likely to be detached from the mounting bracket 1 for replacement and maintenance, the tightness degree between the filter screen assembly 2 and the mounting bracket 1 is greatly influenced by human factors of an operator during the detachment and detachment, certain deviation may exist in the axial installation position of the filter screen assembly 2, the dimensional tolerance of the first sealing ring 4 and the second sealing ring 5 in the axial direction of the filter screen assembly 2 is not well controlled, the tightness degree between the filter screen assembly 2 and the mounting bracket 1 is difficult to be properly controlled, and the situation of over-looseness or over-tightness exists between the filter screen assembly 2 and the mounting bracket 1. The filter screen assembly 2 and the mounting bracket 1 are mounted too tightly, the first sealing ring 4 and the second sealing ring 5 which are arranged along the axial direction of the filter screen assembly 2 are subjected to larger extrusion force, which is beneficial to sealing, but the friction force between the axial end faces of the first sealing ring 4 and the second sealing ring 5 along the filter screen assembly 2 is larger, which may cause the difficulty in rotating the filter screen assembly 2. The installation must be too loose between filter screen subassembly 2 and the installing support 1, form the clearance between first sealing washer 4 and the second sealing washer 5, the frictional force is less or almost no frictional force between the axial terminal surface of two sealing washers along filter screen subassembly 2, be favorable to filter screen subassembly 2 to rotate, nevertheless because the formation clearance between two sealing washers, sealed effect is relatively poor, the filterable air current of filter screen subassembly 2 that does not flow in between first sealing washer 4 and the second sealing washer 5 probably, cause the content of dusts such as batting higher in the follow-up air current.
