[0025] Specifically, the vibration assembly 23 includes a vibrator 231 , and the vibrators 231 are installed on both sides of the box body 21 and below the two threaded tubes 24 .

[0026] By adopting the above technical solution, the filter can prevent the filter bag 3 from being blocked by the vibration of the two vibrators 231 when necessary, thereby ensuring the normal operation of the air filtration work and better meeting the work needs.

[0027] Specifically, the vibration assembly 23 also includes an elastic rubber tube 232, a connecting ring 233 and a damper 234. The elastic rubber tube 232 is installed on both sides of the box body 21 and above the two vibrators 231.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the drying processing device 8 includes a mounting plate 81, a silica gel desiccant 83 and a mesh box 85. The mounting plate 81 is arranged below the box body 21. A plurality of mesh boxes 85 are installed on one side of the mounting plate 81 close to the box body 21. The inner side of the mesh box 85 is filled with silica gel desiccant 83.

[0032] By adopting the above technical solution, the staff can dry the air to a certain extent through the cooperation of the silica gel desiccant 83 and the mesh box 85 when necessary, so as to better meet the work needs in different situations.

When the air filtration work is in progress, the silica gel desiccant 83 in each mesh box 85 can dry the air to a certain extent, which better meets the work needs in different situations. The second screw 84 plays the role of connecting the box body 21 and the mounting plate 81.

[0036] The structure and principle of the filter bag 3 in the utility model, and the activated carbon assembly 4 composed of a connecting cloth bag, a nano-activated carbon filter plate, a HEPE filter screen, a sponge block, an ultraviolet lamp and a photocatalyst coating plate have been disclosed in a multi-bag air filter disclosed in Chinese patent application No. 202220283191.7. Its working principle is that when using this device, when dust and air enter the filter bag, the dust and air will simultaneously enter the connecting cloth bag, and through the setting of the nano-activated carbon filter plate, the excellent odor adsorption of activated carbon is used to absorb the odor in the air, and then when the gas passes through the HEPE When using the HEPE filter, the high density of the HEPE filter can filter out larger bacteria and microorganisms in the air. When the gas continues to flow, it will flow to the photocatalyst coating plate. Through the coordination of the photocatalyst coating plate and the ultraviolet lamp, a photocatalytic reduction reaction can be generated to produce free hydroxyl radicals and active oxygen with extremely strong oxidizing ability. It has a strong photooxidation-reduction function, can oxidize and decompose various organic compounds and some inorganic substances, can destroy the cell membrane of bacteria and solidify the protein of viruses, can kill bacteria and decompose organic pollutants, thereby killing and decomposing bacteria and harmful substances in the gas.

[0037] The structure and principle of the vibrator 231 in the utility model have been disclosed in an easy-to-clean concrete mixing device disclosed in Chinese patent application No. 201821054815.8. Its working principle is composed of components such as springs, mass blocks, and motors. When the spring or mass block is subjected to external force from the motor, elastic deformation or displacement will occur, thereby generating vibration.

[0038] The structure and principle of the damper 234 in the utility model have been disclosed in a smart home washing machine shock absorbing device disclosed in Chinese patent application No. 201721446985.6. Its working principle is composed of a piston and an oil tank, the interior of which is filled with oil. When the object moves, the piston will move in the oil, thereby consuming energy and slowing down the movement of the object.

[0039] The working principle and use process of the utility model are as follows: when it is necessary to use the air filter, the staff rotates the air inlet pipe 1 and the air outlet pipe 7 respectively, and the air inlet pipe 1 and the air outlet pipe 7 are respectively threadedly connected with the two threaded pipes 24 in the length-adjusting vibration device 2, so that the air inlet pipe 1 and the air outlet pipe 7 rotate and move, thereby adjusting the overall length of the filter, and then the top plate 5 and the multiple filter bags 3 are installed and fixed through the cooperation of the two threaded holes 22 and the two first screws 6, and then the air inlet pipe 1 and the air outlet pipe 7 are connected to the corresponding pipes, and the air enters the box body 21 from the air inlet pipe 1 and other structures, and is discharged through the air outlet pipe 7 and other structures after being filtered by the multiple filter bags 3 and processed by the multiple activated carbon components 4. In this process, the staff can start the vibrators in the two vibration components 23 231, thereby driving the box body 21 and the filter bag 3 and other structures to vibrate, thereby preventing the filter bag 3 from being blocked. In addition, the elastic rubber tube 232 and the damper 234 on one side of the two connecting rings 233 can buffer the vibration caused by the vibrator 231. When all the air is discharged, the work is completed; when necessary, the staff can unscrew the various threaded blocks 82 in the drying treatment device 8 and put enough silica gel desiccant 83 into each mesh box 85, and then install each threaded block 82 back through the thread. When the air filtration work is in progress, the silica gel desiccant 83 in each mesh box 85 can dry the air to a certain extent, which better meets the work needs in different situations. The second screw 84 serves to connect the box body 21 and the mounting plate 81.
