[0044] The two long edges of the top of the air inlet cover 6 are fixedly connected with a clamping plate 61, and the opposite sides of the two clamping plates 61 are fixedly installed with a convex ball 62. The wall surface of the air inlet cover 6 composed of the length and height is provided with an oblique air outlet 63.

[0046] An ultraviolet lamp group 1001 is fixedly installed between the three photocatalytic plates 10. The photocatalytic plates 10 and the ultraviolet lamp group 1001 together constitute a solid strong oxygen free radical purification section. The front plate 13 is threadedly installed with a first bolt 131 in a symmetrical shape up and down, and a hand groove is opened in the middle of the front plate 13. The hand groove is convenient for the operator to manually remove the front plate 13 from the installation opening opened at the front end of the processing box 4. Multi-sided rubber strips 132 are embedded and installed in the middle of the left and right sides of the front plate 13 to enhance the sealing of the front plate 13 during the embedding installation at the front end of the processing box 4 to prevent air leakage or dirt clogging.

[0047] When in use, the purification device is installed in the bathroom in the form of a suspended ceiling, the bottom of the air duct 16 is extended downward to be installed at the air inlet of the urinal and the squat pit, and the relay fan 3 and the EC fan 7 are activated at the same time, so that the airflow is guided from the air inlet of the urinal and the squat pit through the air guide cover 15 and the air inlet cover 6 under the suction guidance of the air duct 16 to the inside of the air supply pipe 2, and the dirty air is sucked into the inside of the treatment box 4 through the air supply pipe 2; the dirty air is purified by the primary filter 8, the bipolar ion air purifier 9, the photocatalytic plate 10, the negative ion generator 11 and the chemical filter 12 in sequence to obtain clean air, and under the blowing of the EC fan 7, the clean air is sent back to the bathroom through the connection of the air outlet duct 5 at the fresh air outlet of the bathroom, so as to realize the rapid purification of the dirty air in the bathroom.

[0048] When the polluted air enters the inner side of the treatment box 4, it first contacts the primary filter 8, and the primary filter 8 intercepts and filters the large particles in the polluted air, thereby achieving preliminary purification of the polluted air; then the polluted air contacts the bipolar ion air purifier 9, and the positive and negative electrodes are broken down through the dielectric barrier, and at the same time, a pulse voltage is used to generate high electron energy, so that the gas is broken down, chemical bonds are opened, and a mixture including electrons, various ions, atoms and free radicals is generated; these high-energy electrons, free radicals and other active particles are used to interact with the pollutants in the exhaust gas, so that the pollutant molecules are decomposed in a short time, and various subsequent reactions occur to degrade the pollutants.

[0049] Then the air contacts the photocatalytic plate 10 through the bipolar ion air purifier 9, and the photocatalytic plate 10 is irradiated by the ultraviolet lamp group 1001. The light source with bactericidal power of the ultraviolet lamp group 1001 itself is irradiated on the photocatalytic plate 10 made of titanium dioxide, and photocatalytic reaction is carried out in combination with water and oxygen in the air, which can quickly produce high-concentration advanced bactericidal ion groups: hydroxide ions, superoxide ions, negative oxygen ions, hydrogen peroxide ions, etc. The oxidizing and ionic properties of these advanced oxidation particles can quickly decompose chemical harmful gases and odors, precipitate suspended particles, and kill viruses, bacteria, molds and other microbial pollutants.

[0050] Then the air contacts the negative ion generator 11 through the photocatalytic plate 10. The negative oxygen ions generated by the negative ion generator 11 can reduce the active oxygen or oxygen free radicals generated by atmospheric pollutants, nitrogen oxides, cigarettes, etc., and reduce the harm of excessive active oxygen to the human body, which has a health care effect on the human body. It can also neutralize the positively charged air dust and settle it without charge, so that the air is purified.

[0051] Finally, the air contacts the chemical filter 12 through the negative ion generator 11. The chemical filter 12 body adopts active composite materials as high-performance carriers and is modified by AOP-KF solid alkali. It has a porous structure and a large specific surface area. Under the characteristics of the honeycomb structure, the gas to be treated is quickly adsorbed onto the active material through physical adsorption and chemical decomposition of the chemical filter, and undergoes polymerization reaction with the catalyst to convert harmful components into carbon dioxide and water; finally, the purified air is re-delivered to the bathroom through the EC fan 7 and the air outlet duct 5, realizing the circulation and purification treatment function of the dirty air inside the bathroom.

[0052] The primary filter 8, bipolar ion air purifier 9, photocatalytic plate 10, negative ion generator 11 and chemical filter 12 are used to purify the polluted air layer by layer. The bipolar ion air purifier 9 and the solid strong oxygen free radical purification section can generate active purification factors to decompose ammonia and hydrogen sulfide, so as to comprehensively realize the purification effect of the purification equipment on the adsorption and reaction of various pollutants and improve the purification efficiency. Among them, the use of LED ultraviolet lamps can accelerate the generation of purification factors and purify quickly to achieve the purpose of sterilization and odor removal.

[0053] By installing the front plate 13 and the rear plate 14 at the front and rear ends of the primary filter 8, the bipolar ion air purifier 9, the photocatalytic plate 10, the negative ion generator 11 and the chemical filter 12, the above structure is effectively modularized, so that the primary filter 8, the bipolar ion air purifier 9, the photocatalytic plate 10, the negative ion generator 11 and the chemical filter 12 can be installed on the inner side of the treatment box 4 through the installation port, so that the above structure can be easily installed and maintained inside the treatment box 4, and it is also convenient to adaptively adjust the specific installation position of the above structure on the inner side of the treatment box 4, so as to flexibly adjust the purification capacity according to different air pollution conditions, and can adapt to different application scenarios and working conditions accordingly, thereby improving the practicability and efficiency of the equipment.

[0054] By means of the guide rail 101 installed on the inner wall of the air inlet box 1, the airflow introduced into the air inlet box 1 through the air duct 16, the air guide cover 15 and the air inlet cover 6 can be divided into multiple streams for drainage. At the same time, the overall structural strength of the air inlet box 1 can be enhanced, so that the air inlet box 1 can smoothly guide the strong wind force generated by the relay fan 3, and reduce the noise level of the air inlet box 1 and the air inlet cover 6 under the disturbance of high-speed airflow.

[0055] By clamping the air inlet hood 6 with the help of the clamping plate 61 and the guide bar 101, the air inlet hood 6 can be easily disassembled and installed at the bottom of the air inlet box 1, which is convenient for cleaning the dirt inside the air inlet hood 6 at a later time; at the same time, the embedded setting of the convex ball 62 on the guide bar 101 can help the clamping plate 61, enhance the close strength of the clamping plate 61 on the guide bar 101, and prevent the air inlet hood 6 from being misplaced or falling off.

[0056] By using the inclined air outlet 63 as the air guide cavity for the dirty air to enter the air inlet box 1 through the air inlet hood 6, it is possible to prevent the dirt in the dirty air from flowing back or falling back into the bathroom. The bottom pocket 64 is used to provide a storage space for these larger particles or the dirt that falls inside the air inlet hood 6 under the action of gravity, thereby preventing the dirt from flowing back and polluting the bathroom again, thereby ensuring the cleanliness of the bathroom interior and air.

[0057] The rubber membrane 65 is used as a medium for dirt to accumulate in the bottom pocket 64. While the rubber membrane 65 is used to protect the inner cavity of the bottom pocket 64, after the air guide cover 15 and the air inlet cover 6 are removed, the hook ring 67 can be hooked with fingers to lift the bottom pocket 64 from the rubber membrane 65 with the help of the upward pulling effect of the hook ring 67 on the rubber edge 66, thereby lifting the dirt from the bottom pocket 64, and the dirt can be directly poured out by turning the air inlet cover 6 upside down without leaving any dead corners; the air inlet cover 6 can also be turned upside down, and the rubber membrane 65 can be lifted while being rinsed with clean water, and the oblique air outlet 63 can be rinsed at the same time, so as to realize the convenient cleaning of the air inlet cover 6, thereby facilitating the convenient cleaning and reuse of the air inlet cover 6.

[0058] The top and bottom of the cylinder 31 are isolated from the air supply duct 2 by the shock-absorbing gasket ring 32, which can reduce the transmission of mechanical vibration and play a shock-absorbing role. The corners between the cylinder 31 and the air supply duct 2 are shielded by the silencer plate 33 and the composite wave peak cotton 34 to achieve shock-absorbing protection for the cylinder 31 while absorbing and weakening the noise of the relay fan 3 when it operates in the middle of the inner side of the cylinder 31, thereby reducing the operating noise; and the cylinder 31 is locked and positioned on the inner side of the air supply duct 2 in combination with the four support plates 35, so that the relay fan 3 can not only run smoothly inside the air supply duct 2, but also be in a silent operation state, without generating noise pollution, thereby improving the user experience of bathroom users, and is particularly suitable for places with high noise requirements, such as subways, hospitals, schools and libraries.

[0059] By hooking the hook plate 41 corresponding to the bayonet 141 in the middle of the rear plate 14, and fitting the rear plate 14 on the inner wall of the treatment box 4, each air purifying structure like the primary filter 8 can be stably inserted into the treatment box 4 and can run smoothly inside the treatment box 4.
