The lower ends of the two first conduits 6 extend into the interior of the public toilet body 1 and are fixedly connected and communicated with an air suction hood 7. There are two compartments inside the public toilet body 1, and an air suction hood 7 is provided at the upper end of each compartment. The other ends of the two first conduits 6 are respectively connected and communicated with the two ends of a connecting pipe 8. The connecting pipe 8 is located above the public toilet body 1. The rear end of the connecting pipe 8 is fixedly connected and communicated with a second conduit 9. The rear end of the first conduit 6 is fixedly connected and communicated with a purification box 10. The lower end of the purification box 10 is fixedly connected to the upper end of the public toilet body 1. Inside the purification box 10, a number of groups of limiting grooves 11 are provided on the upper and lower sides. Inside a number of groups of limiting grooves 11, there are fixed frames 12 slidably connected. Inside a number of fixed frames 12, there are sequentially arranged an activated carbon filter 13, a HEPA filter 14, and a photocatalyst filter 15 from front to back. The activated carbon filter 13 can adsorb odors and harmful gases, capture odor molecules through its porous structure, and significantly reduce unpleasant smells in the air. The HEPA filter 14 can effectively capture tiny particles in the air and improve the air cleanliness. The photocatalyst filter 15 uses photocatalytic reactions to decompose harmful substances and converts harmful gases into harmless substances through photocatalyst materials to further purify the air. At the left ends of a number of fixed frames 12, there are second handles 16 fixedly installed. At the rear side of the purification box 10, there is an air suction fan 18. The lower end of the air suction fan 18 is fixedly connected to the upper end of the public toilet body 1. The input end of the air suction fan 18 is fixedly connected and communicated with a third conduit 17, and the front end of the third conduit 17 is connected and communicated with the inside of the purification box 10.

[0026] Refer to Figure 2-7As shown in the figure, ventilation holes 19 are penetrated and opened at both the left and right ends of the public toilet body 1. Installation frames 20 are fixedly communicated with the outer sides of the two ventilation holes 19. An electric fan 21 is arranged inside the installation frame 20. A dust-proof plate 22 is fixedly connected to the outer side of the installation frame 20. The dust-proof plate 22 blocks dust and particulate matter in the air outside, preventing dust and particulate matter from entering the public toilet body 1 and polluting its environment. Fixed blocks 23 are fixedly connected to the four corner positions on the outer side of the installation frame 20. A sliding rod 24 is fixedly connected between the front two fixed blocks 23. A threaded rod 25 is rotatably installed between the rear two fixed blocks 23. A servo motor 28 is fixedly installed at the upper end of the rear upper fixed block 23. The output end of the servo motor 28 penetrates through the rear upper fixed block 23 and is fixedly connected to the upper end of the threaded rod 25. A cleaning block 26 is threadedly connected to the outer surface of the threaded rod 25. The front end of the cleaning block 26 is slidably connected to the outer surface of the sliding rod 24. A cleaning brush 27 is fixedly connected to the inner side of the cleaning block 26. The cleaning brush 27 abuts against the outer side of the installation frame 20. By driving the threaded rod 25 to rotate through the servo motor 28, the threaded rod 25 drives the cleaning block 26 to move, and then drives the cleaning brush 27 to clean the dust and particulate matter accumulated on the surface of the dust-proof plate 22. Fixed piles 29 are fixedly connected to the four corner positions at the lower end of the public toilet body 1. An anti-slip pad 33 is provided at the lower end of the fixed pile 29. When the electric telescopic rod 31 drives the universal wheel 34 to move into the installation groove 30, the anti-slip pad 33 at the lower end of the fixed pile 29 contacts the ground, increasing the friction between the public toilet body 1 and the ground, preventing the public toilet body 1 from sliding, and thus improving safety and stability. An installation groove 30 is opened at the bottom of the fixed pile 29. The top of the inner wall of the installation groove 30 is fixedly connected with an electric telescopic rod 31. The output end of the electric telescopic rod 31 is fixedly connected with a movable plate 32. The movable plate 32 is slidably connected inside the installation groove 30. A universal wheel 34 is fixedly connected to the bottom of the movable plate. When it is necessary to move the public toilet body 1, the four electric telescopic rods 31 extend simultaneously to drive the movable plate 32 to move downward until the universal wheel 34 extends out of the installation groove 30.

[0027] Working principle and usage process of the utility model: Specifically, the suction fan 18, the electric fan 21, the servo motor 28 and the electric telescopic rod 31 are all electrically connected to an external controller. When it is necessary to purify the dirty air inside the public toilet body 1, the suction fan 18 is started, and the dirty air is conveyed into the purification box 10 through the suction hood 7, the first conduit 6, the connecting pipe 8 and the second conduit 9. The dirty air conveyed into the purification box 10 sequentially passes through the activated carbon filter 13, the HEPA filter 14 and the photocatalyst filter 15. The activated carbon filter 13 is used to remove odors and volatile organic compounds, the HEPA filter 14 captures particulate matter in the air, and the photocatalyst filter 15 is used to treat residual gas pollutants. The exhaust fan discharges the purified air into the environment. After long-term use, the filtering effect of the activated carbon filter 13, the HEPA filter 14 and the photocatalyst filter 15 will decrease. At this time, the fixed frame 12 is taken out from the limiting groove 11 opened inside the purification box 10 through the second handle 16, and the activated carbon filter 13, the HEPA filter 14 and the photocatalyst filter 15 inside the fixed frame 12 are replaced to prevent the inability to effectively remove odors, fine particulate matter and residual gas pollutants in the dirty air due to the decrease in the filtering effect.

[0028] The electric fan 21 arranged inside the installation frame 20 extracts the external air into the public toilet body 1, and the dustproof plate 22 blocks dust and particulate matter in the air to prevent dust and particulate matter from entering the public toilet body 1 and polluting its environment. After long-term use, a large amount of dust and particulate matter will accumulate on the dustproof plate 22, resulting in the blockage of the dustproof plate 22. The servo motor 28 drives the electric screw rod 25 to rotate, and the rotation of the screw rod 25 drives the cleaning block 26 to move downward, thereby driving the cleaning brush 27 inside the cleaning block 26 to move downward to clean the dust and particulate matter accumulated on the outer surface of the dustproof plate 22.

[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the utility model claimed.
