When the connecting block 34 moves, the cleaning brush 36 connected to the connecting block 34 starts to move along the surface of the filter assembly 22, thereby cleaning the surface of the filter assembly 22 and sweeping off the dust on the filter assembly 22. When the connecting block 34 moves up and down, the two sliding blocks 33 also slide up and down along the two fixed rods 31, so that the cleaning brush 36 moves more stably. By setting up the cleaning assembly 3, when there is dust on the filter assembly 22 that may be blocked, the cleaning assembly 3 can be started to clean the surface of the filter assembly 22. There is no need to take out the air filter device 2. The operation is simple and convenient to use. At the same time, by setting multiple filter layers, the filtering effect of the air filter device 2 is further enhanced.

[0036] Embodiment 2:

[0037] like Figure 1 , 3, 4, and 5: the air filter device 2 also includes a fixing plate 23, which is fixedly connected to the inner wall of the fixing frame 21 near the bottom end.

An air inlet 11 is provided at the front end of the air-conditioning box 1, and a slot 12 is provided on one end of the air-conditioning box 1 near the air inlet 11. The air filter device 2 is inserted through the insert The groove 12 is slidably inserted into the interior of the air-conditioning box body 1, and two fixed grooves 13 are also provided at the bottom of the inner wall of the air-conditioning box body 1. The bottom of the fixed frame 21 is fixedly connected with two fixed blocks 28 which are consistent with the positions of the two fixed grooves 13, and the two fixed blocks 28 are respectively inserted into the two fixed grooves 13. The top of the fixed frame 21 is fixedly connected with a handle 27. A limit plate 14 is provided on the side of the air-conditioning box body 1 close to the pull plate 26.

When the connecting block 34 moves, the cleaning brush 36 connected to the connecting block 34 starts to move along the surface of the filter assembly 22, thereby cleaning the surface of the filter assembly 22 and sweeping off the dust on the filter assembly 22. When the connecting block 34 moves up and down, the two sliding blocks 33 also slide up and down along the two fixed rods 31, so that the cleaning brush 36 moves more stably. When the cleaning brush 36 cleans the dust up and down, by setting the dust box 25, the swept dust can fall into the dust box 25 for centralized treatment. When a certain amount of dust is collected in the dust box 25, the limit plate 14 is pulled, so that the limit plate 14 drives the insertion rod 16 from The dust box 25 is moved out of the fixing hole on the dust box 25, and the limit plate 14 is slightly rotated to make the limit plate 14 disengage from the contact with the dust box 25, and the dust box 25 is pulled out of the sliding groove 24 by the pulling plate 26, and the dust in the dust box 25 is cleaned out. After cleaning, the dust box 25 is inserted into the sliding groove 24 again, and the limit plate 14 is pulled again. The tension spring 15 is stretched at the same time, and the insertion rod 16 is inserted into the fixing hole, and the limit plate 14 is released. The resilience of the tension spring 15 fixes the insertion rod 16 stably in the fixing hole to prevent the dust box 25 from falling out. When it is necessary to replace the fixing frame 21, pull the handle 27 to move the fixing block 28 from the narrower side of the fixing groove 13 to the wider side, and lift the handle 27 upwards to take out the fixing frame 21. When installing, align the fixing frame 21 with the slot 12, move the fixing frame 21 downward to clamp the fixing block 28 on the fixing groove 13.
