[0032] Specifically, four fans 14 drive the air to enter the interior of the box body 1 from the rear guide plate 3, pass through the filter plate 7 and then flow out from the front guide plate 3 to filter the air. When the filter plate 7 is filtered in the air filter for too long, dust will be blocked in the filter holes on the rear side of the filter plate 7, resulting in poor filtering effect of the filter plate 7 in the air filter. The motor 15 can be started to drive the meshing between the gear 12 and the rack 13 to control the brush 11 to move up and down at the rear end of the inner wall of the box body 1. The brush 11 slides on the rear end of the inner wall of the box body 1 and moves up and down on the rear side of the filter plate 7 through the front side of the brush 11 to clean the dust remaining on the rear side of the filter plate 7, so as to avoid the dust from clogging the filter holes on the rear side of the filter plate 7, resulting in poor filtering effect of the filter plate 7 in the air filter, which leads to poor filtering effect of the air filter, thereby improving the working efficiency of the air filter.

[0033] Embodiment 2:

[0035] Specifically, a pluggable splicing piece is provided on the rear side of the air inlet frame 2 and the case body 1. The pressure plate 10 can be moved so that the pressure plate 10 compresses the spring 9 to disengage the clamping shaft 8 from the top of the clamping block 6, and then the nut 5 is unscrewed from the right end of the lock shaft 4, so that the staff can remove the lock shaft 4 from the inside of the two L-shaped blocks and the two fixed blocks, so as to facilitate the removal of the air inlet frame 2 from the rear side of the case body 1. At the same time, through the action between the spring 9 and the pressure plate 10, the side of the pressure plate 10 facing the case body 1 is tightly pressed against the rear sides of the two clamping blocks 6, so that the air inlet frame 2 can be securely installed on the rear side of the case body 1. Through the simple structure, it is convenient to realize the quick disassembly and installation between the air inlet frame 2 and the case body 1, and it is convenient to improve the work efficiency of the air filter installation.

[0036] Working principle: The air is driven by four fans 14 to enter the interior of the box body 1 from the rear guide plate 3, and then flows out from the front guide plate 3 after being filtered by the filter plate 7, so as to filter the air. When the filter plate 7 is filtered in the air filter for too long, the filter holes on the rear side of the filter plate 7 will be clogged with dust, resulting in poor filtering effect of the filter plate 7 in the air filter. The gear 12 and the rack 13 can be driven to mesh by starting the motor 15, and the brush 11 can be controlled to move up and down at the rear end of the inner wall of the box body 1. The brush 11 moves up and down at the rear end of the inner wall of the box body 1. The front side of the brush 11 slides up and down on the rear side of the filter plate 7 to clean the dust remaining on the rear side of the filter plate 7. The pressure plate 10 can be pressed to compress the spring 9 to disengage the card shaft 8 from the top of the card block 6, and then the nut 5 is unscrewed from the right end of the lock shaft 4, so that the staff can remove the lock shaft 4 from the inside of the two L-shaped blocks and the two fixed blocks, and the air inlet frame 2 can be disassembled from the rear side of the box body 1, so as to improve the working efficiency of the air filter and the working efficiency of assembling the air filter.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
