The threaded ring 611 can drive the cleaning cotton 612 to move through the rotation of the threaded rod 5, so that the cleaning cotton 612 can clean the dust attached to the air outlet.

[0045] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the second cleaning assembly 7 includes a collar 711, a cleaning pad 712 is fixedly connected to one side of the collar 711, and both ends of the cleaning pad 712 are fixedly connected to second magnetic blocks 713, and both ends of one side of the collar 711 are fixedly connected to corrugated sleeves 714, and the interiors of the two corrugated sleeves 714 are fixedly connected to first springs 715;

[0048] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the second cleaning assembly 7 includes a collar 711, a cleaning pad 712 is fixedly connected to one side of the collar 711, and both ends of the cleaning pad 712 are fixedly connected to second magnetic blocks 713, and both ends of one side of the collar 711 are fixedly connected to corrugated sleeves 714, and the interiors of the two corrugated sleeves 714 are fixedly connected to first springs 715;

[0049] The middle part of the collar 711 is movably connected to the threaded rod 5, one side of the cleaning pad 712 is in contact with the controller body 1, the second magnetic block 713 and the first magnetic block 613 are magnetically attracted to each other, the inner parts of the corrugated sleeve 714 and the first spring 715 are movably connected to the threaded rod 5, one side of the corrugated sleeve 714 is fixedly connected to the fixed long plate 9, and both ends of the first spring 715 are fixedly connected to the corrugated sleeve 714;

[0050] With the above solution, during the secondary cleaning of the residual stains by the cleaning pad 712, the collar 711 drives the corrugated sleeve 714 to move along the rod wall of the threaded rod 5, the corrugated sleeve 714 stretches and lengthens, the first spring 715 stretches and lengthens, and at the same time, the elastic rod 1011 and the second spring 1012 are stretched by the cleaning pad 712.

[0052] Example 4

[0053] like Figure 2 and Figure 4 As shown, the reset module 10 includes an elastic rod 1011, the outer wall of the elastic rod 1011 is movably sleeved with a second spring 1012, and both ends of the elastic rod 1011 are fixedly connected with a connecting plate 1013;

[0054] The two ends of the second spring 1012 are respectively fixedly connected to the two connecting plates 1013, and one side of the two connecting plates 1013 is respectively fixedly connected to the fixed long plate 9 and the cleaning pad 712;

[0055] The above scheme is adopted: one connecting plate 1013 is connected and fixed by the cleaning pad 712, and the fixed long plate 9 is connected and fixed to the other connecting plate 1013, so that the elastic rod 1011 can be connected and fixed by the two connecting plates 1013, and the two ends of the second spring 1012 are connected and fixed, and the second spring 1012 is movably sleeved on the outer wall of the elastic rod 1011. The elastic rod 1011 is made of elastic material, so that the elastic rod 1011 can be deformed as the distance between the fixed long plate 9 and the cleaning pad 712 changes. At the same time, the cleaning pad 712 can be pulled by the elastic recovery of the elastic rod 1011 and the second spring 1012, so that the cleaning pad 712 is away from the cleaning cotton 612.

[0056] Example 5

[0057] like Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the liquid guide module 14 includes a spiral hose 1411, the outer wall of the spiral hose 1411 is fixedly connected to a torsion spring tube 1412, one end of the torsion spring tube 1412 is fixedly connected to a rotating rod 1413, and both ends of the rotating rod 1413 are rotatably connected to a rotating plate 1414;

[0058] One end of the spiral hose 1411 is fixedly connected to the cleaning cotton 612, and the other end of the spiral hose 1411 is fixedly connected to the micro water pump 11. One side of the two rotating plates 1414 is fixedly connected to the controller body 1;

[0059] One side of the fixed short plate 8 is fixedly connected to the controller body 1, and the fixed short plate 8 is a symmetrical structure. One side of the fixed long plate 9 is fixedly connected to the controller body 1, one end of the threaded rod 5 is rotatably connected to the fixed long plate 9, and one side of the cleaning liquid barrel 13 is fixedly connected to the controller body 1;

[0060] The above scheme is adopted: the rotating plate 1414 is supported and fixed by the controller body 1, and the rotating plate 1414 limits the rotation of the rotating rod 1413, and the rotating rod 1413 is fixed to one end of the torsion spring tube 1412, so that the rotating rod 1413 can wrap the spiral hose 1411 through the elastic force of the torsion spring tube 1412, and the two ends of the spiral hose 1411 are respectively fixedly connected to the micro water pump 11 and the cleaning cotton 612. Because the spiral hose 1411 is an elastic structure, when the spiral hose 1411 is wound by the rotation of the torsion spring tube 1412 and the rotating rod 1413, the elasticity of the end of the spiral hose 1411 connected to the micro water pump 11 is relatively large. When the spiral hose 1411 extends as the cleaning cotton 612 moves, the elasticity of the end connected to the micro water pump 11 is relatively small and the tube diameter gradually decreases, and the tube mouth gradually closes;

[0061] The timer 12 is used to time the micro water pump 11 to regularly deliver cleaning liquid to the cleaning cotton 612 through the cleaning liquid barrel 13 and the spiral hose 1411, so that the cleaning cotton 612 can always remain moist, so that the cleaning cotton 612 will not become stiff due to drying and cannot clean the dust well. The cleaning pad 712 is a relatively dry cleaning structure, and the stains remaining on the cleaning cotton 612 can be cleaned secondary through the cleaning pad 712.

[0062] The working principle and use process of the present invention:

[0063] First, the driving motor 2 drives the two first bevel gears 411 to rotate through the rotating rod 3. The two first bevel gears 411 are meshed with the second bevel gear 412 at the same time to make the second bevel gear 412 rotate, and the second bevel gear 412 drives the threaded rod 5 to rotate. The threaded rod 5 is threadedly rotated with the threaded ring 611, so that the threaded ring 611 drives the cleaning cotton 612 to move along the rod wall of the threaded rod 5. At this time, the cleaning cotton 612 cleans the air outlet at the bottom of the controller body 1. Because the cleaning cotton 612 is relatively moist, dust is easy to agglomerate and easy to clean, thereby preventing fly ash from entering the inside of the controller body 1.

[0064] When the cleaning cotton 612 cleans the dust, the cleaning cotton 612 drives the first magnetic blocks 613 at both ends to move. When the threaded ring 611 moves to the end of the threaded rod 5 close to the fixed long plate 9, the first magnetic block 613 and the second magnetic block 713 attract each other. The cleaning cotton 612 then drives the first magnetic block 613 to move in the opposite direction along the rod wall of the threaded rod 5 through the reverse rotation of the driving motor 2, so that the second magnetic block 713 drives the cleaning pad 712 to move through the first magnetic block 613, and the cleaning pad 712 performs secondary cleaning on the air outlet.

[0065] During the secondary cleaning process of the cleaning pad 712, the ring 711 drives the corrugated sleeve 714 to move along the rod wall of the threaded rod 5. At this time, the corrugated sleeve 714 extends and lengthens, and the first spring 715 stretches and lengthens. At the same time, the elastic rod 1011 and the second spring 1012 are stretched through the cleaning pad 712. After the cleaning cotton 612 contacts the second bevel gear 412, the initial cleaning and the secondary cleaning are completed. At this time, the cleaning pad 712 is pulled back due to the elastic force of the first spring 715, the elastic rod 1011 and the second spring 1012, so that the cleaning pad 712 moves along the rod wall of the threaded rod 5 toward the fixed long plate 9 through the ring 711, and the second magnetic block 713 and the first magnetic block 613 are not adsorbed, and the operation is completed.

[0066] It should be noted that in the above embodiments, the description of each embodiment has its own emphasis, and for parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
