There are two groups of rotating frames 12. The rotating frame 12 rotates along with the rotating shaft 13. The first filter plate 11 and the second filter plate 17 are fixed inside the rotating frame 12. The first filter plate 11 and the second filter plate 17 rotate along with the rotating frame 12.

[0036] The surface of the external frame 9 is provided with an air inlet groove 10. The bottom of the air inlet groove 10 is provided with a first insertion groove 14 and a second insertion groove 35. A first baffle 15 is inserted into the first insertion groove 14. A movable groove 29 is provided on the surface of the first baffle 15. A second extension block 28 is fixed on the surface of the first baffle 15 close to one side of the second baffle 16.

An extension plate is arranged on the surface of the rotating ring 31. The extension plate rotates along with the rotating ring 31. A brush is arranged on the surface of the extension plate. The brush rotates along with the extension plate. After the first baffle 15 rises in the first insertion groove 14 and the first baffle 15 is located on one side of the first filter plate 11 and the second filter plate 17, the brush on the surface of the rotating ring 31 contacts the surfaces of the first filter plate 11 and the second filter plate 17. A second baffle 16 is inserted into the second insertion groove 35. The first baffle 15 and the second baffle 16 can move up and down in the first insertion groove 14 and the second insertion groove 35. A connecting plate 18 is fixed at the bottom of the first baffle 15 and the second baffle 16. The first baffle 15 and the second baffle 16 move along with the connecting plate 18. The inside of the second baffle 16 is empty. A plurality of insertion holes 26 are provided at the bottom of the second baffle 16. After the insertion holes 26 rise, the bottom of the first air outlet pipe 24 is inserted into the inside of the insertion holes 26. A plurality of third air outlet pipes 27 are arranged on the surface of the second baffle 16 close to one side of the first baffle 15. The air inside the first extension block 23 can enter the second baffle 16 through the insertion holes 26. The gas in the second baffle 16 is ejected through the third air outlet pipes 27. The gas ejected from the third air outlet pipes 27 blows on the surfaces of the first filter plate 11 and the second filter plate 17, so that the dust accumulated on the surfaces of the first filter plate 11 and the second filter plate 17 is blown off. And the direction of the gas blown out by the third air outlet pipes 27 is opposite to the direction in which the fan 3 makes the air enter the inside of the housing 1. The connecting frame 7 is fixed on the surface of the fixed frame 5. The first filter plate 11 and the second filter plate 17 are arranged on the surface of the rotating shaft 13, so that the air enters the inside of the external frame 9 after passing through the first filter plate 11 and the second filter plate 17. The first filter plate 11 and the second filter plate 17 filter the air.

[0037] A cylinder 20 is fixed to the bottom of the external frame 9. The cylinder 20 can drive the U-shaped rod 19 to move. The U-shaped rod 19 is fixed to the surface of the connecting plate 18. The connecting plate 18 moves along with the U-shaped rod 19. A first extension block 23 is fixed to the surface of the external frame 9. The intake pipe 22 is connected to the surface of the first extension block 23. The other end of the intake pipe 22 is connected to an inflation device. The inflation device injects gas into the interior of the first extension block 23 through the intake pipe 22. The interior of the first extension block 23 is empty. A first air outlet pipe 24 and a second air outlet pipe 25 are fixed to the surface of the first extension block 23. Multiple groups of the first air outlet pipe 24 and the second air outlet pipe 25 are fixed. There are multiple groups of the second air outlet pipe 25. The air blown out from the second air outlet pipe 25 can blow on the surface of the rotating ring 31, causing the rotating ring 31 to rotate. The brush on the surface of the rotating ring 31 rotates along with the rotating ring 31, and the brush brushes on the surfaces of the first filter plate 11 and the second filter plate 17. When the fan 3 rotates, air enters the interior of the housing 1 through the interior of the external frame 9 and the through holes 4. The air is filtered through the first filter plate 11 and the second filter plate 17. The air inside the housing 1 can be discharged through the air outlet holes 2. A filter screen is arranged inside the air outlet holes 2. The first baffle 15 moves upward in the first insertion groove 14, and the first baffle 15 blocks the second filter plate 17, so that the air is only filtered through the first filter plate 11. When a large amount of dust accumulates on the surface of the first filter plate 11, the cylinder 20 is driven to drive the U-shaped rod 19 to descend, and the connecting plate 18 descends along with the U-shaped rod 19.

[0038] A fan 3 is provided in the opening 6 for air to flow into the interior of the housing 1. The connecting frame 7 is fixed on the surface of the fixing frame 5. A first filter plate 11 and a second filter plate 17 are provided on the surface of the rotating shaft 13, so that air enters the interior of the external frame 9 after passing through the first filter plate 11 and the second filter plate 17. The first filter plate 11 and the second filter plate 17 filter the air. During use, the first baffle 15 moves upward in the first insertion slot 14, and the first baffle 15 blocks the second filter plate 17, and air is only filtered through the first filter plate 11. When a large amount of dust accumulates on the surface of the first filter plate 11, the U-shaped rod 19 is driven to descend by the cylinder 20, and the connecting plate 18 descends along with the U-shaped rod 19, so that the first baffle 15 descends in the first insertion slot 14. The rotating shaft 13 is driven to rotate by the first motor 8, and the positions of the first filter plate 11 and the second filter plate 17 are swapped, and the air can be continuously filtered through the second filter plate 17. The connecting plate 18 drives the first baffle 15 and the second baffle 16 to rise. The air inlet pipe 22 is connected to an inflation device, and the inflation device injects gas into the interior of the first extension block 23 through the air inlet pipe 22. The first air outlet pipe 24 and the second air outlet pipe 25 are at the bottom of the first extension block 23, and air is ejected from the second air outlet pipe 25 to blow off the dust on the surface of the first filter plate 11. Moreover, the second motor 21 drives the lead screw 33 to rotate, so that the lifting block 32 moves in the lifting groove 34, and the lifting rod 30 moves along with the lifting block 32. The gas blown out by the second air outlet pipe 25 blows onto the surface of the rotating ring 31, so that the rotating ring 31 rotates. During the rotation of the rotating ring 31, the brush on the surface touches the surface of the first filter plate 11 to clean the dust on the surface of the first filter plate 11. And because the rotating ring 31 is rotated by air blowing, the rotating force of the rotating ring 31 is small and will not damage the first filter plate 11. Moreover, after the second baffle 16 rises, the end of the first air outlet pipe 24 is inserted into the insertion hole 26 at the top of the second baffle 16, so that air is ejected from the second air outlet pipe 25 on the surface of the second baffle 16. The air ejected from the second air outlet pipe 25 blows on the other side of the first filter plate 11, and through the blowing on the other side, the dust can fall off more easily from the surface of the first filter plate 11.
