[0021] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0022] like Figure 1-4 As shown, the utility model includes a cover plate 4 which can cover the filter screen 8 on the side wall 1 of the chassis and can be raised and lowered by means of a guide mechanism, a brush 7 for cleaning the filter screen 8 is installed at the lower edge of the cover plate 4, the cover plate 4 is limited by a limiting mechanism, a dust box 12 for collecting dust is arranged below the filter screen 8, and the dust box 12 is detachably connected to the guide mechanism.

[0023] In this embodiment, the guide mechanism includes two guide grooves 2 located on both sides of the filter screen 8 and arranged in parallel, a slider 3 is slidably connected in each guide groove 2, and a cover plate 4 is located between the two guide grooves 2, and the two sides of the cover plate 4 are respectively connected to the two sliders 3. Through the coordinated use of the guide grooves 2 and the sliders 3, the cover plate 4 can slide up and down along the guide grooves 2. Furthermore, each guide groove 2 is fixed to the side wall 1 of the chassis by 3M double-sided tape.

[0024] Furthermore, a limit block 9 is fixed at the lower end of each guide groove 2, and a dust box 12 is located between two limit blocks 9. A connecting plate 13 is fixed on both sides of the dust box 12, and a plug-in column 14 is provided on each connecting plate 13, and a slot 10 for inserting the plug-in column 14 is provided on each limit block 9. The plug-in column 14 and the slot 10 are used in conjunction with each other to realize a detachable connection between the dust box 12 and the guide mechanism, and the dust box 12 is easy to disassemble and assemble. The dust swept by the brush 7 can be collected in the dust box 12, which is convenient for cleaning.

[0025] In this embodiment, the brush 7 is connected to the lower edge of the cover plate 4 by screws.

[0026] In this embodiment, the limiting mechanism includes an iron sheet 11 fixedly mounted on the side wall 1 of the chassis and a magnet sheet 5 mounted on the inner side of the cover plate 4. The iron sheet is fixed to the side wall 1 of the chassis by means of 3M double-sided adhesive tape, and the magnet sheet 5 is fixed to the inner side of the cover plate 4 by means of 3M double-sided adhesive tape. After the cover plate 4 is raised, the limit of the cover plate 4 can be achieved by means of the cooperation between the magnet sheet and the iron sheet.
