The air monitor 3 is a prior art and will not be described here.

[0026] The filtering mechanism includes two support frames 6 fixed at the bottom of the air inlet bin 1 at intervals in front and back, the upper ends of the two support frames 6 extend above the air inlet bin 1, and the first winding roller 5 and the second winding roller 8 are connected to rotate together between the two support frames 6. The first winding roller 5 is located in the air inlet bin 1, and the second winding roller 8 is located outside the air inlet bin 1. The surfaces of the first winding roller 5 and the second winding roller 8 are wound with a flexible filter screen 9. The air outlet of the exhaust pipe 4 is close to the flexible filter screen 9, so that the dust in the exhaust air is adsorbed on the flexible filter screen 9. The two relatively arranged flexible filter screens 9 make the filtering effect better, thereby preventing dust from accumulating on the fan 25 and causing device failure.

[0027] A cleaning mechanism is provided below the two second winding rollers 8. The cleaning mechanism includes a movable plate 11 provided between two front and rear corresponding support frames 6. A movable opening 26 is provided inside the movable plate 11. A limit slide bar 27 is longitudinally penetrated and slidably connected in the movable opening 26. The front and rear ends of the limit slide bar 27 are respectively fixedly connected to the two corresponding support frames 6. The limit slide bar 27 is rectangular, so as to limit the movable block to slide forward and backward. A brush 28 is provided at one end of the movable plate 11 close to the flexible filter screen 9, and a rotating roller 13 is rotatably connected at the other end. One end of the limit slide bar 27 is fixedly connected to two spaced springs 12. The ends of the two springs 12 away from the limit slide bar 27 are fixedly connected to the inner wall of one side of the movable opening 26 close to the rotating roller 13.

[0028] A first motor 14 and a support column 17 are provided between the two filtering mechanisms. The first motor 14 is fixedly installed above the air inlet bin 1. The driving end of the first motor 14 is coaxially fixedly connected to a longitudinally arranged rotating shaft 15. The other end of the rotating shaft 15 is rotatably connected to the support column 17. A cam 16 is fixedly sleeved in the middle of the rotating shaft 15. The first motor 14 drives the rotating shaft 15 to rotate the cam 16 fixedly sleeved thereon. The cam 16 contacts the rotating roller 13 on the side of the movable plate 11, thereby pushing the movable plate 11 forward, so that the bristles 28 on the other side of the movable plate 11 contact the flexible filter screen 9 to clean the dust on the flexible filter screen 9. Then, the spring 12 is reset, and the bristles 28 reciprocate with the flexible filter screen 9, which has a shaking effect and makes the cleaning effect better. A dust discharge trough 18 is provided under the two movable plates 11. The dust discharge trough 18 is fixedly connected to the corresponding support frame 6. The dust discharge trough 18 is in a "∧" shape. The cleaned dust falls into the trough body of the dust discharge trough 18 and is automatically discharged out of the device through the "∧"-shaped trough body. There is no need to manually handle the dust cleaned on the filter screen, thereby ensuring the reuse of the flexible filter screen 9.

[0029] The front and rear ends of the two first winding rollers 5 are coaxially fixedly connected with the first shaft 7 penetrating the support frame 6, and the rear ends of the two second winding rollers 8 are coaxially fixedly connected with the second shaft 10 penetrating the support frame 6. A second toothed belt 20 is sleeved between the rotating shaft 15 and the first shaft 7 located in the front, and a first toothed belt 19 is sleeved between the two first shafts 7 located in the front. Transmission belts 21 are sleeved between the two second shafts 10 and the two first shafts 7 located in the rear. When the first motor 14 drives the rotating shaft 15 to rotate clockwise, the second toothed belt 20 drives one of the first shafts 7 to rotate, and the first toothed belt 19 drives the other first shaft 7 to rotate, so that the two first winding rollers 5 coaxially fixed on the two first shafts 7 rotate clockwise, and the two transmission belts 21 drive the two second shafts 10 and the two second winding rollers 8 coaxially fixed thereon to rotate clockwise through the two first shafts 7 respectively, and the flexible filter screen 9 wound on the right first winding roller 5 and the second winding roller 8 is wound downward, and the flexible filter screen 9 wound on the left first winding roller 5 and the second winding roller 8 is wound upward. When the flexible filter screen 9 is wound to the end, the first motor 14 changes direction of rotation, and the flexible filter screen 9 inside the air inlet bin 1 is replaced and the flexible filter screen 9 is cleaned outside the bin.

[0030] Working principle: When the utility model is working, the second motor 24 drives the fan 25 to rotate to form wind pressure to suck air into the device through the air inlet ventilation plate 2, the air enters the air monitor 3 to complete data monitoring, and then is discharged to the two filtering mechanisms through the exhaust port of the exhaust pipe 4, so that the dust in the air is adsorbed on the two flexible filter screens 9.

[0031] When the dust on the flexible filter 9 in the bin body accumulates to a certain extent and needs to be cleaned, the first motor 14 drives the rotating shaft 15 to rotate clockwise, the second toothed belt 20 drives one of the first shafts 7 to rotate, and the first toothed belt 19 drives the other first shaft 7 to rotate, so that the two first winding rollers 5 coaxially fixed on the two first shafts 7 rotate clockwise, and the two transmission belts 21 drive the two second shafts 10 and the two second winding rollers 8 coaxially fixed thereon to rotate clockwise through the two first shafts 7, respectively, so that the flexible filter 9 wound on the right first winding roller 5 and the second winding roller 8 is wound downward, and the flexible filter 9 wound on the left first winding roller 5 and the second winding roller 8 is wound upward. The first motor 14 drives the rotating shaft 15 to rotate the cam 16 fixedly sleeved thereon, and the cam 16 contacts the rotating roller 13 on the side of the movable plate 11, thereby pushing the movable plate 11 forward, so that the bristles 28 on the other side of the movable plate 11 contact the flexible filter 9, clean the dust on the flexible filter 9, and then reset by the spring 12. There is an ash discharge trough 18 under each of the two movable plates 11. The ash discharge trough 18 is fixedly connected to the corresponding support frame 6. The ash discharge trough 18 is in a "∧" shape. The cleaned dust falls into the trough body of the ash discharge trough 18 and is automatically discharged out of the device through the "∧" shaped trough body. When the first motor 14 rotates clockwise, the flexible filter screen 9 on the left cleaning mechanism is wound upward to the end and the cleaning is completed. The first motor 14 rotates counterclockwise, and the flexible filter screen 9 on the right cleaning mechanism is rolled upward and the cleaning is completed. The exhausted air passes through the two filter devices and is discharged out of the device through the two air outlet ventilation plates 23.
