Specifically, the first motor 13 drives the moving screw 12 to rotate, so as to drive the driving block 11 and the sliding plate 9 to move. When the sliding plate 9 moves, the two toothed belts 10 are driven to move. Since the two toothed belts 10 are respectively engaged with the two rotating gears 8, the two rotating gears 8 are driven to rotate, so as to drive the two rotating frames 5 and the two air flushing boxes 6 to turn over, thereby enabling the two air flushing boxes 6 to be close to the filter plate 2.

[0061] The air outlet assembly is arranged on the filter box 1 and is used for conveying air in the two air flushing boxes 6. The air outlet assembly comprises an air pump 14, two conveying pipes 15 and two spring pipes 16. The air pump 14 is arranged on one side of the filter box 1.

[0064] In the embodiment, the current cleaning method of the filter plate 2 is usually to brush the dust on the filter plate 2 by a brush, but the brush is difficult to clean the dust inside the filter plate 2. In the present application, when the dust inside the filter plate 2 needs to be cleaned, first, the sealing door 3 close to one end of the fan blade 4 is opened, then the first motor 13 drives the moving screw rod 12 to rotate, thereby driving the driving block 11 and the sliding plate 9 to move. The sliding plate 9 drives the two toothed belts 10 to move when moving, because the two toothed belts 10 are engaged with the two rotating gears 8 respectively, thereby driving the two rotating gears 8 to rotate relatively, thereby driving the two rotating frames 5 and the two air flushing boxes 6 to overturn, so that the two air flushing boxes 6 are close to the filter plate 2. The gas pump 14 intermittently sends the gas into the conveying pipe 15 and the spring pipe 16, so that the high-pressure gas is blown into the air flushing box 6, thereby forming a pulse of the gas, and then the dust inside the filter plate 2 is flushed out. In addition, the second motor 19 drives the rotating rod 17 to rotate, and the rotating rod 17 drives the vibration wheel 18 to knock the filter plate 2 when rotating, thereby knocking the dust inside the filter plate 2 out. Then, the third motor 23 drives the driving rod 21 to rotate, and the driving rod 21 drives the second bevel gear 22 and the first bevel gear 20 to rotate when rotating, thereby driving the fan blade 4 to reverse, so that the dust cleaned on the filter plate 2 is blown out of the filter box 1, thereby completing the cleaning of the dust inside the filter plate 2.
