[0029] Reference Figure 2 , 4 The dust box 3 absorbs cotton wool through the exhaust structure 4 at the bottom; the bottom surface of the dust box 3 is a filter plate 9; the exhaust structure 4 includes an exhaust box 41 and an exhaust fan 42, and the exhaust box 41 is sleeved on the bottom of the filter plate 9; the exhaust fan 42 is connected to the exhaust box 41.

[0030] Reference Figure 2 , 4 The folding cover 51 is unfolded by the opening cover structure 8, and the opening cover structure 8 includes a top cover column 81, a limit block 82, a control push rod 83, a control board 84 and a rocker 85. The top cover column 81 is lifted and connected to the inner wall of the dust storage box 3; the limit block 82 is fixed to the side wall of the top cover column 81, and the bottom surface of the limit block 82 abuts against the dust storage box 3, and the bottom surface of the top cover column 81 is not lower than the bottom surface of the dust storage box 3; the control push rods 83 are respectively penetrated and lifted and connected to the bottom surface of the dust removal box 1, and are arranged corresponding to the bottom of the top cover column 81; the control board 84 is fixed to the lower end of the control push rod 83; the rocker 85 extends horizontally and is rotatably connected to the bottom of the control board 84, and the rotation axis of the rocker 85 is located on one side of the rocker 85.

[0031] Reference Figure 2 , 5The folding cover plate 51 is closed by the cover closing structure 7. The cover closing structure 7 includes a cover closing support rod 71, a return spring 72, a slide groove 73 and a sliding frame 74. The cover closing support rods 71 ​​are respectively penetrated and laterally slidably connected to the side wall of the dust removal box 1, and the cover closing support rods 71 ​​are set at a height corresponding to the gap filling plate 52; one end of the return spring 72 is fixed to the side wall of the dust removal box 1, and the other end is fixed to and drives the cover closing support rod 71 away from the dust storage box 3; the slide groove 73 is fixed to the outside of the dust removal box 1 and is set at a height corresponding to the cover closing support rod 71; the sliding frame 74 is sleeved on the dust removal box 1 and accommodated in the slide groove 73, and the sliding frame 74 can abut against the cover closing support rod 71.

[0032] The working process of the present application is as follows: fold the folding cover plate 51 inward, insert the dust storage box 3 into the dust removal box 1, rotate the seesaw 85 and drive the control board 84 to rise, the control board 84 drives the surrounding control push rods 83 to push up the top cover column 81, the top cover column 81 rises and pushes up the surrounding folding cover plates 51, and the folding cover plates 51 are spliced ​​to the adjacent gap-filling plates 52.

[0033] Then push the pull rod 62 into the dust removal box 1, the roller blind 61 opens, and the curtain 10 falls between the folding cover 51 and the gap-filling plate 52 to form a connected state; then turn on the exhaust fan, the shorter cotton wool adheres to the filter plate 9, and the longer cotton wool is easily captured by the fixing needle 53 and adheres to the folding cover 51 to form thin sheet-like cotton wool.
