[0030] The specific implementation process of the present invention is as follows: first, when the air purifier needs to be placed on a table to work, the bottom frame 1 can be placed on the table. At this time, the rubber suction cups 24 on the bottom frame 1 can fit tightly with the table. Then, the push blocks 207 on the second support frames 203 on both sides are pushed. Under the pushing action of the push blocks 207, the adjustment blocks 206 can be pushed to move synchronously through the connecting plates 205 until the adjustment blocks 206 move out of the adjustment slots 202 in the first support frame 201. Then, the staff can pull the second support frame 203 upward. 03. Under the movement of the second support frame 203, the protective shell 3 can be driven to move synchronously through the fixed frame 210 on the first sleeve 209, so as to adjust the working height of the air purifier. After adjusting to the appropriate height, the push block 207 can be released.

[0031] Then the rotating shaft 25 on the bottom frame 1 can be rotated. At this time, the rotating shaft 25 can drive the second bevel gears 27 on both sides to rotate stably through the first bevel gear 26, and then can drive the corresponding threaded rod 28 to rotate at the same time. At this time, under the rotation of the threaded rod 28, the corresponding rubber piston 30 can be driven to move toward the middle at the same time through the threaded connecting sleeve rod 29, and then the air inside the rubber suction cup 24 can be sucked through the air storage frame 23. At this time, negative pressure is formed inside each rubber suction cup 24, and then the air purifier can be conveniently and stably adsorbed and fixed on the table through the bottom frame 1, ensuring the stability and safety of the subsequent working state of the air purifier.

[0032] When there is no suitable place to place it indoors, the air purifier can be adsorbed on the indoor wall to work. It only needs to push the push blocks 207 on the second support frames 203 on both sides. Under the pushing action of the push blocks 207, the fixing rod 208 can be pushed to slide inside the first sleeve 209 through the connecting plate 205. At this time, the fixing rod 208 can push the fixing plate 212 to slide inside the fixing frame 210 until the positioning rod 213 on the fixing plate 212 moves out of the positioning grooves 211 on the upper and lower sides of the fixing frame 210. At this time, the protective shell 3 can be rotated. Under the rotation action of the protective shell 3, the first sleeve 209 can be driven to rotate on the second support frame 203 through the fixing frame 210, and the second support frame 203 is The fixing rod 208 and the fixing plate 212 on the fixing rod 208 remain stationary until the protective shell 3 rotates 90°. At this time, the bottom frame 1 moves from the bottom of the protective shell 3 to the side of the protective shell 3, and then the push block 207 can be released. At this time, under the elastic action of the first spring 204, the fixing plate 212 on the fixing rod 208 can be driven to move and reset through the connecting plate 205. At this time, the positioning rod 213 on the fixing plate 212 can be stably engaged with the positioning grooves 211 on the front and rear sides of the fixing frame 210 to complete the engagement and fixation. Then, the air purifier can be conveniently and stably adsorbed and fixed on the wall through the rubber suction cup 24, and the protective shell 3 is in a vertical state to ensure the stability and safety of the subsequent working state of the air purifier.

[0033] When the air purifier starts working, the servo motor 7 on the mounting rod 6 can drive the drive shaft 8 to rotate clockwise. Under the clockwise rotation of the drive shaft 8, the guide block 904 can be pushed to move into the second sleeve 902 through the inclined surface in the guide groove 901. Therefore, the drive shaft 8 can drive the exhaust fan 12 to rotate in the ventilation groove 5 and suck the air without driving the second sleeve 902. At this time, the indoor air enters the air purifier through the various through holes 18 on the protective shell 3, and then passes through the filter plate 915 to filter larger particles, such as dust, hair, etc., to protect the subsequent HEPA filter element 19, activated carbon filter element 20 and light Catalytic filter element 21, extending their service life; then under the action of HEPA filter element 19, it can filter tiny particles in the air, such as pollen, smoke, mold spores, bacteria and other harmful substances; then under the action of activated carbon filter element 20, it can adsorb odors and harmful gases in the air, such as formaldehyde, benzene, toluene and other volatile organic compounds; finally, under the continuous irradiation of ultraviolet lamp 22, combined with photocatalytic filter element 21, it can decompose organic matter and odor in the air through photocatalytic reaction, and has antibacterial effect; in summary, the air can be filtered and purified at multiple stages, and then the air is discharged through ventilation slot 5 and second mesh plate 13 to complete the air purification work.

[0034] After the air purifier has been working for a long time, when there are many large particles of impurities attached to the filter plate 915, the servo motor 7 can be driven to drive the drive shaft 8 to rotate counterclockwise. At this time, the drive shaft 8 can move the second sleeve 902 on the guide block 904 to rotate synchronously through the guide groove 901, and then drive the first circular gear 905 to rotate synchronously. The second circular gear 906 meshing on both sides can drive the corresponding driven shaft 907 to rotate. The driven shaft 907 can drive the reciprocating screw rod 909 to rotate stably by moving the limit rod 908. Under the rotation of the reciprocating screw rods 909 on both sides, the threaded support plate 910 can be driven to reciprocate up and down, and then the guide frame 912 can be pushed to perform automatic and stable reciprocating up and down motion through the connecting rod 911. During the movement of the guide frame 912, Driven by the water pump 920, the clean water inside the water tank 917 can be sucked through the hose 919 and transported to the guide frame 912, and then sprayed out through the guide holes 914. At this time, under the up and down reciprocating motion of the guide frame 912, combined with the water spraying of each flexible brush 913 and each guide hole 914, the filtering surface of the filter plate 915 can be automatically and stably scrubbed comprehensively. During the scrubbing process, the baffle 921 on the support plate 910 can move synchronously with the guide frame 912, thereby blocking the sprayed water to prevent it from contacting the HEPA filter element 19 in large quantities and affecting the stability of the subsequent working state of the HEPA filter element 19. The waste water after scrubbing can automatically flow to the bottom of the protective shell 3 through the first mesh plate 10, and can be discharged through the drain pipe 11 to the sewer.

[0035] After the air purifier is finished working, the latch rod 16 on the cover plate 4 can be pulled outward to make it move out of the latch slot 17 on the protective shell 3. At this time, the cover plate 4 can be lifted up and moved out of the protective shell 3 to complete the disassembly and separation work. At this time, the HEPA filter element 19, the activated carbon filter element 20 and the photocatalytic filter element 21 can be taken out and replaced. The replaced HEPA filter element 19, the activated carbon filter element 20 and the photocatalytic filter element 21 can be placed in their original positions. Then the cover plate 4 can be snapped onto the protective shell 3. At this time, the protective The top of the shell 3 can be engaged in the limit groove 14, and the limit rod 908 can be engaged in the slide groove inside the driven shaft 907, and the top of the HEPA filter element 19 can be engaged in the ventilation groove 5 in the middle of the cover plate 4, and then the clamping rod 16 on the cover plate 4 can be released. At this time, under the elastic action of the third spring 15, the clamping rod 16 can be driven to automatically engage in the clamping groove 17 on the protective shell 3, completing the clamping installation between the protective shell 3 and the cover plate 4, and then the air purifier can perform subsequent stable operation.
