[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 As shown, a self-cleaning air compressor filter comprises a filter box body 1, a side pipe 2, a positioning mechanism 3, a disassembly assembly 4 and a support frame 5, wherein the positioning mechanism 3 is arranged on the outside of the filter box body 1, the support frame 5 is arranged on the bottom of the filter box body 1, and a replacement assembly 6 is arranged inside the filter box body 1; the disassembly assembly 4 comprises a connection frame 41 arranged at the bottom of the filter box body 1, a support frame 42 arranged on the inner wall of the connection frame 41, a positioning member 43 arranged inside the connection frame 41, and an air filter cotton body 44 arranged inside the connection frame 41 for preliminary filtration,

[0022] refer to Figure 2 and Figure 3 As shown, the connection frame 41 includes a fixing rod 411 disposed inside, a spring 412 disposed outside the fixing rod 411 for providing elastic force, and a moving block 413 slidably connected to the outside of the fixing rod 411 .

[0023] The connecting frame 41 further includes a latch 7 disposed inside the moving block 413 for fixing, and a pressing plate 8 slidably connected to the outside of the moving block 413 for fixing the air filter cotton body 44 .

[0024] The positioning member 43 includes a positioning rod 431 fixedly connected to the bottom of the air filter cotton body 44 and a positioning hole 432 opened inside the support frame 42 .

[0025] It should be noted that when the device is in use, under the action of the air filter cotton body 44, the gas entering the filter element body 62 can be initially filtered to prevent the dust in the environment from clogging the filter element body 62. When the air filter cotton body 44 is used for a long time, it needs to be replaced. First, the connection frame 41 is disassembled through the positioning mechanism 3. After the connection frame 41 is disassembled, the staff rotates the bolt 7 to disengage the bolt 7 from the inside of the moving block 413 and the pressure plate 8, and then pulls the pressure plate 8 to disengage the bottom of the pressure plate 8 from the top of the air filter cotton body 44. Then the staff can pull the air filter cotton body 44 to disengage the positioning rod 431 from the inside of the positioning hole 432, and then the air filter cotton body 44 can be disassembled and assembled, thereby facilitating the staff to replace the air filter cotton body 44. At the same time, it can prevent the increase in the replacement cycle of the filter element body 62 and increase the service life of the filter element body 62.

[0026] refer to Figure 4 and Figure 5 As shown, the replacement component 6 includes a mounting plate 61 fixed to one side of the inner wall of the filter box body 1 for installation, a filter element body 62 arranged at the bottom of the mounting plate 61, a top pipe 63 arranged inside the filter box body 1 for conveying gas, and a valve 64 arranged on the outside of the top pipe 63 for controlling the flow of gas.

[0027] The mounting plate 61 includes a screw mechanism 9 disposed inside and a moving frame 10 disposed outside the screw mechanism 9 .

[0028] The mounting plate 61 further includes a clamping ring 11 disposed at the bottom for fixing the filter element body 62 , and a soft pad 12 disposed on the inner circle of the clamping ring 11 .

[0029] It should be noted that when the staff needs to replace or disassemble the filter element body 62, they first start working the screw mechanism 9. Under the action of the screw mechanism 9, the movable frame 10 can be driven to move. When the movable frame 10 moves, it drives the retaining ring 11 to move, and then the retaining ring 11 can drive the soft pad 12 to move, so that the soft pad 12 is separated from the outside of the filter element body 62, thereby facilitating the staff to replace the filter element body 62. At the same time, under the action of the soft pad 12, the inner ring of the retaining ring 11 can be prevented from causing damage to the outside of the filter element body 62.

[0030] Working principle: When the device is in use, the outside air first passes through the air filter cotton body 44. Under the action of the air filter cotton body 44, dust in the outside air can be prevented from entering the interior of the filter element body 62, thereby extending the service life of the filter element body 62. At the same time, when the air filter cotton body 44 needs to be replaced or cleaned after being used for a long time, the connection frame 41 is first disassembled and assembled through the positioning mechanism 3. The positioning mechanism 3 includes a positioning plate and two positioning bolts. Under the action of the two positioning bolts, the filter box body 1 can be tightly connected to the connection frame 41. The positioning bolts make the connection The frame 41 is disengaged from the filter box body 1, and then the staff rotates the bolt 7 to disengage the bolt 7 from the inside of the moving block 413 and the pressure plate 8. At the same time, the staff can slide the moving block 413 to extend or compress the spring 412 to fix the air filter cotton body 44 of different thicknesses. Then the staff pulls the air filter cotton body 44 to disengage the positioning rod 431 from the inside of the positioning hole 432, and then the air filter cotton body 44 can be disassembled, assembled and replaced, which can extend the service life of the filter element body 62 to a certain extent, while reducing the use cost of the filter element body 62.
