The control mechanism also includes a first fixed plate 24 fixedly connected to one side of the machine body 1. A worm 22 is rotatably connected to the first fixed plate 24, and one side of the worm 22 is meshed with the worm wheel 21 for transmission.

A limit spring 25 is provided between the top of the first fixed plate 24 and the first staggered toothed disk 23, and the first staggered toothed disk 23 is limited in movement by the limit spring 25.

[0040] In the present invention, the transmission mechanism includes a second pulley 34 fixedly connected to the other end of the driving rod 30, a third pulley 35 is fixedly connected to the top of the first connecting rod 4, the outside of the first pulley 3 is connected to the outside of the second pulley 34 and the third pulley 35 by the same belt 36, and the rotation of the first pulley 3 drives the second pulley 34 and the third pulley 35 to rotate synchronously through the belt 36.

[0041] In the present invention, the linkage mechanism includes a transmission gear 31 fixedly connected to the driving rod 30, a second fixed plate is fixedly connected to one side of the body 1, a short shaft 26 is rotatably connected to the second fixed plate, one end of the short shaft 26 is fixedly connected to the second staggered toothed plate 27, one side of the second staggered toothed plate 27 is meshed with the first staggered toothed plate 23, the other end of the short shaft 26 is fixedly connected to the first reduction gear at a position parallel to the transmission gear 31, a linkage rod 28 is rotatably connected to one side of the body 1, a second reduction gear 29 is fixedly connected to the linkage rod 28 corresponding to the first reduction gear and the transmission gear 31, the two sides of the second reduction gear 29 are respectively meshed with the transmission gear 31 and the first reduction gear for transmission, the rotation speed of the transmission gear 31 is reduced by the first reduction gear and the second reduction gear 29, the use of reduction gears and staggered toothed plates belongs to the prior art, therefore, the working principle of the reduction gears and staggered toothed plates will not be explained and elaborated.

[0042] In the present invention, a storage cavity is provided on one side of the body 1, and a third partition 39 is fixedly connected to the interior of the storage cavity. A placement box 17 is movably mounted inside the storage cavity, and an air outlet is provided on one side of the third partition 39. A plurality of placement racks 18 are fixedly connected to the internal array of the placement box 17, and filter plates 19 are respectively placed inside the plurality of placement racks 18. A plurality of ultraviolet sterilization lamps 15 are fixedly connected to the internal array of the body 1, and a water baffle 40 is fixedly connected to the other side of the second partition 16. A vent is provided on the other side of the body 1, and a universal wheel is installed on the bottom array of the body 1. The ultraviolet sterilization lamp 15 is used to perform ultraviolet sterilization on the disinfected air sucked after the spraying of the medicine. Opening a disinfection solution placement port on any side below the body 1 and placing a water pump inside the body 1 to suck the disinfection solution to the water inlet pipe 8 are both conventional operations and belong to the prior art. Therefore, they are not described in the application materials of the present invention.

[0043] Working principle: when the filter plate 19 needs to be replaced, the driving motor 2 is started in reverse, and the first pulley 3 is driven to rotate in the opposite direction synchronously by the driving motor 2. At the same time, the second pulley 34 and the third pulley 35 are driven to rotate in the opposite direction synchronously by the belt 36. The reverse rotation of the second pulley 34 drives the driving rod 30 to rotate, and the rotation of the driving rod 30 drives the rotation of the transmission gear 31. The rotation of the transmission gear 31 drives the rotation of the second reduction gear 29. The rotation of the second reduction gear 29 drives the first reduction gear to rotate. The rotation of the first reduction gear drives the rotation of the short shaft 26. The rotation of the short shaft 26 drives the rotation of the second staggered toothed disc 27, and at the same time engages with the first staggered toothed disc 23, thereby driving the rotation of the first staggered toothed disc 23. The rotation of the first staggered toothed disc 23 drives the rotation of the worm 22. The rotation of the worm 22 drives the worm wheel 21 to rotate, and the rotation of the worm wheel 21 drives the rotation of the third connecting rod 20. The rotation of the third connecting rod 20 drives the placement box 17 to flip over. When the internal structure of the placement box 17 is flipped out of the body 1, the drive motor 2 stops working. At this time, the operator takes out the filter plate 19 inside the placement box 17, puts in a new filter plate 19, and then the drive motor 2 starts forward again. At this time, the second pulley 34 and the third pulley 35 are driven by the belt 36 to rotate forward synchronously. The forward rotation of the second pulley 34 drives the driving rod 30 to rotate forward, and at the same time drives the worm 22 to rotate forward, thereby driving the worm wheel 21 to rotate forward, thereby driving the placement box 17 to reset and flip. After the placement box 17 is reset, the drive motor 2 continues to keep the forward start;

[0044] At this time, the water pump inside the body 1 works to draw the disinfectant solution inside the body 1 into the spray pipe 6 through the water inlet pipe 8, and at the same time, the spray treatment is carried out through the nozzle 7, and the rotation of the third pulley 35 drives the rotation of the first connecting rod 4, and the rotation of the first connecting rod 4 drives the first fan blade 5 to rotate, and the rotation of the first fan blade 5 atomizes the sprayed disinfectant solution, effectively improving the disinfection treatment of the air drawn into the body 1;

[0045] Since the worm wheel 21 cannot continue to rotate after the placement box 17 is reset, the worm gear 21 cannot continue to rotate, thereby causing the worm 22 to be unable to rotate normally. When the worm 22 remains stationary, the first staggered toothed disc 23 cannot mesh with the second staggered toothed disc 27. When the second staggered toothed disc 27 continues to rotate, the first staggered toothed disc 23 cannot mesh with the second staggered toothed disc 27 and thus moves downward along the slide block through the slide groove. At the same time, the limit spring 25 generates an upward thrust on the first staggered toothed disc 23, so that when the first staggered toothed disc 23 cannot mesh with the second staggered toothed disc 27, it repeatedly moves up and down along the worm 22, and at the same time, the driving rod 30 keeps rotating normally.

[0046] The rotation of the driving rod 30 drives the rotation of the fourth bevel gear 33, and the rotation of the fourth bevel gear 33 drives the rotation of the third bevel gear 32. The rotation of the third bevel gear 32 drives the rotation of the second connecting rod 9. The rotation of the second connecting rod 9 drives the synchronous rotation of the second bevel gear 11 and the second fan blade 10. The rotation of the second bevel gear 11 drives the rotation of the driven rod 12 through the first bevel gear 14. The rotation of the driven rod 12 drives the rotation of the third fan blade 13. The rotation of the third fan blade 13 and the second fan blade 10 generates a suction force on the inside of the machine body 1. Through this suction force, air enters the inside of the machine body 1 from the air inlet on the placement box 17. At the same time, the air is subjected to particle capture and filtration treatment through the filter plate 19. The filtered air is sprayed and attracted to the bottom of the machine body 1, and is subjected to ultraviolet sterilization treatment through the ultraviolet sterilization lamp 15. Finally, the purified air is discharged from the inside of the machine body 1 through the rotation of the second fan blade 10.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
