[0003] Air purifiers are products that can effectively improve air cleanliness. They are mainly divided into household and commercial types. The core performance component of an air purifier is the filter element. The filtration efficiency of the filter element directly determines the purification efficiency and effect of the air purifier. The filter element can remove a small amount of solid particles in the liquid or air to protect the normal operation of the equipment or the cleanliness of the air.

[0004] The activated carbon filter element is made of high-quality fruit shell charcoal and coal-based activated carbon as raw materials, supplemented with food-grade adhesives, and processed by high-tech technology and special processes. It integrates adsorption, filtration, interception, and catalysis, and can effectively remove organic matter, residual chlorine and other radioactive substances in water, and has the effects of decolorization and odor removal. In the prior art, the filling of activated carbon powder is generally done manually, which is troublesome on the one hand and cannot achieve a good filling effect.

DETAILED DESCRIPTION

[0022] Reference Figure 1-4 A processing device for a filter element in an air purifier comprises a platform 1, a processing box 2 is fixedly arranged on the top of the platform 1, a conveyor belt 3 is arranged in the platform 1, the conveying surface of the conveyor belt 3 is flush with the upper end surface of the platform 1, and both ends of the conveyor belt 3 are respectively connected with a conveying wheel 4, and the rotation centers of the two conveying wheels 4 are respectively fixedly connected with a rotating shaft 5, and the two rotating shafts 5 are rotatably connected to the platform 1, and a filter element filling structure is arranged in the processing box 2.

A disinfectant liquid is installed on the side of the other fixed plate 11 away from the hydraulic cylinder 6. The disinfectant liquid is located in another independent space. The disinfectant liquid is input into the filter cartridge through the connecting pipe 10, so that the liquid can be input before the filter element is filled. Since the outer wall of the filter cartridge has a membrane structure and can only pass through air, the disinfectant input into the filter cartridge will not leak out, and the inner wall of the filter cartridge can be disinfected. A dual-purpose pump 16 is respectively provided at the connection between the two connecting pipes 10 and the corresponding fixed plates 11. A conveying bucket 12 is connected to the starting end of the conveyor belt 3. The conveying bucket 12 is tilted and the bottom is flush with the top of the conveyor belt 3. A feed port 13 is provided on the side of the processing box 2 close to the conveying bucket 12, and a discharge port 14 is provided on the side of the processing box 2 away from the conveying bucket 12. Box doors 15 are vertically slidably connected to the feed port 13 and the discharge port 14, and the filter cartridge is conveyed through the feed port 13 and the discharge port 14.

[0024] The outer wall of the extension tube 7 is slidably connected with a buffer block 17, and the bottom of the buffer block 17 is fixedly connected with a sealing plate 18 of an arc structure. The sealing plate 18 is fixed against the filter cartridge, and a plurality of grooves 19 are provided on the top of the buffer block 17. A spring 20 is fixedly arranged in each groove 19. The sealing plate 18 can be compressed on the outer wall of the filter cartridge by the spring 20, thereby ensuring that the filter cartridge is in a state, and the top roller of the plurality of springs 20 is fixedly connected with a bracket plate 21, and the bracket plate 21 is fixedly arranged on the outer wall of the extension tube 7. The buffer block 17 passes through the layered plate 8 and is slidably connected with the layered plate 8. A rack 22 is fixedly connected to both sides of the bracket plate 21, and a first gear 23 is meshed on the side of the two racks 22 away from the extension tube 7, and each first gear 23 is away from the side of the rack 22 Both are meshed with a second gear 24, and the rotation centers of the two second gears 24 are fixedly connected with a connecting shaft 25. The two connecting shafts 25 are respectively connected with a positioning plate 26. When the two positioning plates 26 are rotated to a vertical state, they jointly fix the filter cartridge, which can also have a positioning effect, thereby ensuring that the two filter covers 28 are coaxially aligned with the two sides of the filter cartridge. Circular connecting ports 27 are respectively penetrated on both sides of the processing box 2, and a filter cover 28 is respectively sealed and slidably connected in the two connecting ports 27. The two filter covers 28 are respectively located at the two bottoms of the filter cartridge and are coaxially arranged. The part of each filter cover 28 located outside the processing box 2 is abutted against a telescopic rod 29, and the fixed ends of the two telescopic rods 29 are fixedly provided with a fixed block 30, and the two fixed blocks 30 are fixedly provided on the top of the platform 1.

[0025] An ultraviolet lamp 31 is fixedly installed on the top of the processing box 2 on one side of the fixed plate 11 containing activated carbon powder, and a feed pipe 32 is arranged on the side of the ultraviolet lamp 31. The feed pipe 32 passes through the inner top wall of the processing box 2. An air outlet is opened on the top wall of the processing box 2 away from the ultraviolet lamp 31, and the air outlet is sealed with a filter screen 33. The buffer block 17 and the sealing plate 18 are both made of rubber material, the connecting pipe 10 adopts a rubber hose structure, the height of the feed port 13 and the discharge port 14 are the same as the filter cartridge, a sealing layer is provided at the connection between the processing box 2 and the conveyor belt 3, and the connection between the two outlets 9 and the connecting pipe 10 are sealed with solenoid valves, and the input and outflow of activated carbon powder and disinfectant liquid are controlled by the solenoid valve and the dual-purpose pump 16.

[0026] When the present invention is in use, the filter cartridge is placed on the conveying bucket 12. Under the action of the conveyor belt 3, the filter cartridge will enter the processing box 2 through the feed port 13. When it moves to the bottom of the buffer block 17, the hydraulic cylinder 6 is started, so that the hydraulic cylinder 6 will drive the extension pipe 7 to move downward. At the same time, the rack and pinion transmission and the gear transmission work to rotate the two positioning plates 26 to a vertical state, so that the filter cartridge can be effectively positioned directly below the extension pipe 7, and the two filter covers 28 are aligned with the two sides of the filter cartridge. After the filter cover 28 is assembled with the filter cartridge through the telescopic rod 29, the extension pipe 7 extends into the filter cartridge;

[0027] First, the disinfecting liquid is input into the filter cartridge through the dual-purpose pump 16. After the disinfecting liquid is completely input, the dual-purpose pump 16 is enabled in reverse to suck the disinfecting liquid back to the initial state. In this way, the inside of the filter cartridge will be completely cleaned and disinfected by the liquid, thereby ensuring the internal environment of the filter cartridge before the filter element is input. The outer wall of the extension tube 7 can be embedded with a heating resistance wire to dry the inside of the filter cartridge, or it can be naturally dried so that the filter cartridge is in a dry state and activated carbon powder is input through another connecting tube 10, so that the filter cartridge is completely filled. This can effectively ensure the quality of the filter element and increase its service life. After the filter cartridge leaves the conveyor belt 3, the filter cartridge can be packaged to complete the processing process, which is convenient for use.
