The filter box 4 is connected through a first air inlet pipe 7, and the air inlet of the dust suction fan 5 is connected to the right side of the filter box 4 through a second air inlet pipe 8. Two slide grooves are provided at the top and bottom of the filter box 4. The filter screen 6 is slidably connected to the two slide grooves. The filter screen 6 can slide longitudinally through the slide grooves, so as to facilitate the replacement of the filter screen 6. A cleaning structure is provided in the filter box 4.

The two ends of the screw 9 are rotatably connected to the top and bottom of the filter box 4 respectively. The two linear guide rods 10 are arranged between the top and the bottom of the filter box 4. The moving plate 11 is respectively connected to the screw 9 and the two linear guide rods 10. A cleaning brush 12 is arranged on the side of the moving plate 11 close to the filter screen 6. The cleaning brush 12 is against one side of the filter screen 6.
