A Hall sensor is installed at the end of the shaft of the motor 601. The Hall sensor is connected to the sensor 14 to monitor the rotation direction and rotation speed of the motor 601, and then feedback is given to the temperature control regulator 301. After the motor 601 is started, the temperature can be adjusted according to the rotation direction and rotation speed of the motor 601, so as to achieve the HEPA adjustment at the motor 601. When the distance between the filter 1 501 and the HEPA filter 2 502 is the same as the filter hole gap of the pre-filter plate 13, the temperature is adjusted synchronously to adapt to VOC gases of different concentrations.

[0038] Please see attached Figure 7 , the connecting component 7 includes a transmission rod 705, which is installed inside the worm gear 603. The transmission rod 705 is connected to the worm gear 603. When the worm gear 603 rotates, the transmission rod 705 is driven to rotate together. The end of the transmission rod 705 away from the worm gear 603 is fixedly connected with a bevel gear 1 704. The transmission rod 705 is connected with the bevel gear 1 704. When the worm gear 603 controls the transmission rod 705 to rotate, the bevel gear 1 704 can be driven to rotate together. The side of the air inlet pipe 2 close to the air pump 10 is rotatably connected with a bevel gear 2 703. The bevel gear 2 703 is meshed with the bevel gear 1 704.

[0039] Please see attached Fig. 9The two supporting assemblies 9 each include a movable plate 901, and the two movable plates 901 are respectively fixedly connected to the opposite sides of the two cleaning plates 805. The opposite sides of the two movable plates 901 are fixedly connected with springs 902. The movable plate 901 is used to connect the spring 902 and the cleaning plate 805. The spring 902 is used to provide elastic support and is made of 65Mn spring steel.

[0040] Working principle: When it is necessary to use this equipment to treat VOC gas indoors, the concentration of VOC gas indoors must be detected first. According to the concentration of VOC gas, the filter hole diameter of the pre-filter plate 13 and the distance between the HEPA filter 1 501 and the HEPA filter 2 502 are adjusted. By starting the motor 601, the motor 601 will control the two worms 602 to rotate synchronously when it rotates. Because the worm 602 is meshed with the worm wheel 603, the two worm wheels 603 are controlled to rotate synchronously when the two worms 602 rotate. Because the worm wheel 603 is connected to the transmission rod 705, when the worm wheel 603 rotates, the transmission rod 705 can be controlled to rotate accordingly. When the transmission rod 705 rotates, the bevel gear 1 704 is controlled to rotate. Because the bevel gear 1 704 is meshed with the bevel gear 2 703, the gear meshing principle is used to control the bevel gear 2 703 to rotate synchronously when the bevel gear 1 704 rotates, thereby driving the two-way threaded rod 701 and the connecting rod 702 to rotate.

[0041] When the bidirectional threaded rod 701 and the connecting rod 702 rotate, the two sliders 503 meshed with the bidirectional threaded rod 701 will move toward each other along the axis of the bidirectional threaded rod 701, so that the two sliders 503 will respectively drive the HEPA filter 1 501 and the HEPA filter 2 502 to move, thereby achieving the purpose of adjusting the distance between the HEPA filter 1 501 and the HEPA filter 2 502, and when the connecting rod 702 rotates, the connecting rod 702 will control the cylindrical gear 404 to rotate, because the cylindrical gear 404 is meshed with the tooth plate 403, and when the cylindrical gear 404 rotates, it will control the tooth plate 403 to move, and the tooth plate 403 is connected to the connecting plate 402, when the tooth plate 403 is controlled by the cylindrical gear 404 to move, it will drive the connecting plate 402 to move, so that the connecting plate 402 will drive the adjustment plate 401 to slide on the rear side of the pre-filter plate 13, thereby achieving the purpose of adjusting the filter hole size of the pre-filter plate 13;

[0042] When the motor 601 is started, the sensor 14 collects the rotation direction and speed of the motor 601 and feeds back to the temperature control regulator 301, so that the temperature control regulator 301 can adjust the temperature of the ultraviolet lamp 303 in a targeted manner. When adjusting the temperature, the cooling fan 307 needs to be started to prevent the ultraviolet lamp 303 from being damaged due to excessive temperature. After the spacing between the HEPA filter 1 501 and the HEPA filter 2 502 and the filter hole size of the pre-filter plate 13 are adjusted, the air pump 10 and the ultraviolet lamp 303 can be started, and the indoor air is sucked into the body 1 through the air pump 10;

[0043] After entering the air inlet duct 2, the air will first pass through the pre-filter plate 13, and the pre-filter plate 13 will pre-filter the larger particles and impurities in the air, and the air entering the air inlet duct 2 will pass through the HEPA filter 1 501 and the HEPA filter 2 502, and the HEPA filter 1 501 and the HEPA filter 2 502 will intercept dust, pollen, microorganisms and other small microorganisms, and the air after passing through the pre-filter plate 13, the HEPA filter 1 501, and the HEPA filter 2 502 will enter the body 1. After entering the body 1, the air will gradually move upward, and the two activated carbon adsorption plates 308 will adsorb VOC molecules in the air, especially formaldehyde and benzene series. At this time, the ultraviolet lamp 303 will photocatalyze the air, and the titanium dioxide catalyst will be activated by the ultraviolet lamp 303 to generate highly active free radicals, and the free radicals will oxidize and decompose VOC to generate carbon dioxide and water, thereby achieving the purpose of purification.

[0044] When the air is photocatalyzed, the two air pumps 306 can be started. The air pump 306 absorbs the purified air through the air pipe 305 and the exhaust pipe 304. After being absorbed through the exhaust pipe 304, the air is discharged from the air pump 306 and returns to the room.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
