[0030] It can be understood that when the fan 7 is started, the air from the outside is drawn into the interior of the air inlet bin 3 through the louvers, and then enters the processing bin 9 through the air inlet bin 3 for deodorization, and then enters the deodorization bin through the processing bin 9, and then is discharged into the air outlet bin 1 through the fan 7 and discharged through the outlet.

[0031] See also Figure 3 , Figure 6 and Figure 8A rotating motor 13 is installed at the center position of the bottom of the bottom plate 8, and the output end of the rotating motor 13 is connected to a rotating shaft 23 that penetrates the processing chamber 9. The bottom end of the outer side of the rotating shaft 23 is rotatably connected to a first crescent slider 29, and a first mounting rod 18 is fixed to the outer side of the first crescent slider 29. A first bidirectional screw groove 24 is provided at the bottom end of the outer side of the rotating shaft 23, and the first bidirectional screw groove 24 cooperates with the first crescent slider 29. When the rotating shaft 23 rotates, the first crescent slider 29 can be reciprocated up and down. A limiting scraper 16 is fixed at the end of the rod 18, a mounting cavity 10 is provided on the outside of the processing chamber 9, and limiting slide grooves 15 cooperating with the limiting scraper 16 are provided on the inner walls on both sides of the mounting cavity 10, and the limiting slide grooves 15 are slidably connected with the limiting scraper 16, and under the action of the first mounting rod 18, the first crescent slider 29 and the limiting scraper 16 can be synchronously moved, and the top of the first crescent slider 29 is rotatably connected with a mounting block 30, and the mounting block 30 is slidably connected with the rotating shaft 23, and the two ends of the processing chamber 9 The inner wall of the mounting block 30 is provided with a tooth groove 31, and the second mounting rods 19 are fixed at both ends of the mounting block 30. When the first crescent slider 29 rises and falls, the mounting block 30 is driven to move synchronously. At this time, the mounting block 30 drives the second mounting rod 19 to move up and down synchronously. The inner rotation of the second mounting rod 19 is connected to the inner shaft 20, and a gear 21 is fixed at one end of the inner shaft 20. The gear 21 moves up and down with the second mounting rod 19. The number of tooth grooves 31 is two, and the inner wall of one side of the two tooth grooves 31 is provided with a gear 21 that interacts with the gear 21. The meshing teeth, when the gear 21 moves inside the tooth groove 31, cooperate with the teeth to realize the rotation of the gear 21, and the rise and fall of the gear 21 will cause the gear 21 to turn differently. The other end of the inner shaft 20 is fixed with a first conical tooth 35, and the internal rotation of the second mounting rod 19 is connected with a second conical tooth 36. The top of the second conical tooth 36 is fixed with a rotating shaft 32 that passes through the second mounting rod 19, and the top of the rotating shaft 32 is fixed with a third filter plate 22, and the second filter plate 11 is installed inside the mounting cavity 10.

[0032] It can be understood that when the rotating motor 13 is started and drives the rotating shaft 23 to rotate, the first bidirectional screw groove 24 on the outer side of the rotating shaft 23 cooperates with the first crescent slider 29, and under the action of the limiting scraper 16 and the limiting slide groove, the first crescent slider 29 is reciprocated up and down, and the limiting scraper 16 is driven up and down by the first mounting rod 18 to reciprocate and scrape the inner side of the second filter plate 11 to avoid clogging. At the same time, when the first crescent slider 29 moves up and down, it drives the mounting block 30 to move up and down, and the second mounting rod 19 follows It moves up and down, and under the action of the mutual cooperation between the tooth groove 31 and the gear 21, when the second mounting rod 19 drives the gear 21 to move up and down, the gear 21 rotates, the gear 21 drives the inner shaft 20 to rotate, the inner shaft 20 drives the first conical teeth 35 to rotate, the first conical teeth 35 drive the second conical teeth 36 to rotate, and the second conical teeth 36 drive the third filter plate 22 to rotate inside the processing chamber through the rotating shaft 32. The third filter plate 22 that moves up and down and rotates cooperates with the second filter plate 11 to better remove odor.

[0033] See also Figure 2 and Figure 3 The processing chamber 9 and the bottom plate 8 are sealed to each other, and a mounting ring 17 is fixed on the top of the processing chamber 9, and the mounting ring 17 is connected to the air inlet chamber 3 through threads.

[0034] It should be noted that the processing chamber 9 can be separated from the base plate 8. When the mounting ring 17 is rotated, the processing chamber 9 gradually rotates upward under the action of the thread, so that the processing chamber 9 is separated from the base plate 8, making it easier to clean impurities and dust on the top of the base plate 8.

[0035] Please pay attention to Figure 1 , Figure 2 , Figure 4 and Figure 5 The interior of the air inlet bin 3 is an arc-shaped structure, and one end of the interior of the air inlet bin 3 is rotatably connected to the first filter plate 4, and the top end of the first filter plate 4 fits against the air inlet bin 3 to avoid gaps where the first filter plate 4 and the air inlet bin 3 fit, causing some larger dust to enter the processing bin 9, and a sliding rail 27 is fixed to the rear surface of the first filter plate 4, and a sliding block 26 is slidably connected to the inside of the sliding rail 27, and one side of the sliding block 26 is rotatably connected to a connecting rod 28 through a hinge seat, and a second bidirectional screw groove 25 is provided at the top end of the outer side of the rotating shaft 23, and a second crescent slider 33 that cooperates with the second bidirectional screw groove 25 is rotatably connected to the top end of the outer side of the rotating shaft 23, and the second crescent slider 33 is fixedly connected to the connecting rod 28.

[0036] It can be understood that the rotating shaft 23 rotates, and the second crescent slider 33 moves up and down under the cooperation of the second bidirectional screw groove 25 and the second crescent slider 33. At this time, the second crescent slider 33 drives the sliding block 26 to move back and forth inside the sliding rail 27 through the connecting rod 28. At this time, the first filter plate 4 can rotate back and forth inside the air inlet bin 3, which can prevent larger suspended matter from clogging the first filter plate 4.

[0037] See also Figure 3 and Figure 7 , slots 14 are provided on the inner walls on both sides of the installation cavity 10 and on the outside of the limiting slide groove 15, and a return spring 34 is installed inside the slots 14, and plug plates 12 cooperating with the slots 14 are provided on both sides of the second filter plate 11, and the cross-sections of the second filter plate 11 and the limiting scraper 16 are both arc-shaped, and the limiting scraper 16 and the second filter plate 11 are in contact with each other, and bristles are provided on one side of the limiting scraper 16.

[0038] It should be noted that the second filter plate 11 is set to pull the extrusion return spring 34 to one side, so that the plug plate 12 on the other side of the second filter plate 11 is disengaged from the slot 14, and then the second filter plate 11 is slightly rotated to pull it out, so that the second filter plate 11 is disengaged from the installation cavity 10, thereby facilitating its replacement.

[0039] In addition, the width of the slot 14 is greater than the width of the plug plate 12, so that when the plug plate 12 squeezes the return spring, the plug plate 12 can rotate slightly inside the slot 14, which facilitates the second filter plate 11 to be separated from the installation cavity 10. At the same time, the bristles on one side of the limiting scraper 16 clean the inner side of the second filter plate 11 up and down to avoid clogging.

[0040] It should be pointed out that the filter hole of the first filter plate 4 is larger than that of the second filter plate 11 and the third filter plate 22, which is convenient for screening and separating suspended matter in the air. A fixing ear is provided on the top of the rotating shaft 32, and the rotating shaft 32 is detachably connected to the third filter plate 22 using bolts with the cooperation of the fixing ear. The material of the second filter plate 11 and the third filter plate 22 is activated carbon.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention.
