[0051] Embodiment 2:

[0052] Please refer to Figures 2 to 4 , a filtering structure of a photocatalytic air purification device of the present utility model. Compared with Embodiment 1, this embodiment further includes:

[0053] A groove 10 is provided inside the front cover 5, an air inlet pipe 11 is provided at the front end inside the tank body 1, channel openings 12 are provided at the upper and lower ends of the front end of the air inlet pipe 11, and it is rotationally fixed to the front end of the tank body 1 through the front cover 5. The channel openings 12 and the groove 10 are mutually fitted and connected. A filter layer plate 13 is fixedly connected below the channel opening 12 inside the air inlet pipe 11, a first induced draft fan 14 is fixedly connected behind the filter layer plate 13 inside the air inlet pipe 11, a water absorption filter plate 15 is fixedly connected behind the first induced draft fan 14 inside the air inlet pipe 11, and a lamp post 16 is fixedly connected to the center of the rear end face of the water absorption filter plate 15.

[0054] A catalytic cavity 17 is provided in the middle of the filtering assembly 9. A nano catalyst 18 is provided on the inner side wall of the catalytic cavity 17. Two partition plates 19 are fixedly connected inside the catalytic cavity 17, and the lamp post 16 penetrates through the centers of the two partition plates 19 and is fixedly connected. The two catalytic cavities 17 can be separated by the partition plates 19 so that air can be filtered through multiple reactions. Ventilation holes are provided on the partition plates 19 so that the reacted air can flow out through the ventilation holes. An air outlet pipe 20 is provided on the right side inside the tank body 1. A second induced draft fan 21 is fixedly connected inside the air outlet pipe 20. By rotating the second induced draft fan 21, the air inside the filtering assembly 9 can be taken out. An ultra-fine filter screen 22 is fixedly connected to the filter layer plate 13, an activated carbon filter plate 23 is fixedly connected inside the filter layer plate 13, a motor 24 is fixedly connected to the center inside the filter layer plate 13, a cleaning brush 25 is fixedly connected to the output end of the motor 24, the dust on the ultra-fine filter screen 22 can be cleaned by rotating the cleaning brush 25, a conical sieve plate 26 is fixedly connected to the upper end of the cleaning brush 25, and holes are reserved at the tip and on the circular surface of the conical sieve plate 26 so that air can flow through.

[0055] The working principle of this embodiment is:

[0056] First, when the first induced draft fan 14 starts to work, the rotation of the first induced draft fan 14 drives the outdoor air to enter the filtering assembly 9 through the front cover 5. The air passing through the air inlet pipe 11 will first pass through the ultra-fine filter screen 22 on the filter layer plate 13 to filter some fine dust in the air, and then pass through the activated carbon filter plate 23 inside the filter layer plate 13 for re-filtering;

[0057] Second, the filtered air will flow out from the rear of the filter layer plate 13 and enter the water absorption filter plate 15 under the guidance of the first induced draft fan 14 to absorb the residual moisture in the air, eliminating the incomplete filtration caused by humidity. Then it enters the catalytic chamber 17 and undergoes filtration treatment through the mutual photocatalytic reaction between the lamp post 16 and the nano-catalyst 18. Subsequently, it flows out from the rear of the partition plate 19, and the first induced draft fan 21 starts to rotate, driving the air to blow out from the rear cover 6 along the air outlet pipe 20 to achieve filtration;

[0058] Third, during use, there is no need to worry about dust accumulation on the ultra-fine filter screen 22 due to long-term use. By turning on the motor 24, the cleaning brush 25 is driven to rotate to clean the dust on the ultra-fine filter screen 22;

[0059] Fourth, the dust after cleaning will fall onto the conical sieve plate 26 due to gravity and slide down along the slope on the conical sieve plate 26 into the groove 10 inside the front cover 5 through the channel opening 12 for collection. To clean it, just rotate the front cover 5 to remove it;

[0060] Fifth, the device is small in size and can be used in many scene space environments. When maintenance is required, by rotating the buckle 7 to disengage it from the clamping post 8 and lifting the cover page 3 above the tank body 1, the interior can be disassembled and cleaned, making it more convenient to use.

[0061] The present utility model provides a filtration structure of a photocatalytic air purification device through improvement. When there is a lot of dust in the air and dust accumulates on the ultra-fine filter screen 22, it can be quickly cleaned and collected through the cleaning brush 25 and the groove 10. By lifting the cover page 3, the interior can be easily cleaned and maintained. Moreover, the device is small in size and applicable to many scenes. Through the two catalytic chambers 17, the reaction efficiency can be effectively improved.
