In use, as shown in fig. 1 to 4, the above-mentioned filtering device 200 is only required to connect the mounting base 210 with the air compressor 100, and to connect the through hole 211 on the mounting base 210 with the air inlet of the air compressor 100. The air may be filtered by the filter cartridge 250 in advance before entering the inside of the air compressor 100 through the air inlet of the air compressor 100. When the filter cartridge 250 needs to be replaced, only the clamping member 240 needs to be rotated, so that after the second clamping portion 2411 on the clamping member 240 is separated from the first clamping portion 221 on the connecting rod 220, the clamping member 240 and the limiting body 230 can be sequentially removed, and finally the filter cartridge 250 is removed, and the process of installing a new filter cartridge 250 is reversed with the above-mentioned removal process. In this way, in the above-mentioned filtering device 200, in the process of disassembling the filter cartridge 250, since the disassembly and assembly of the mounting base 210 and the air compressor 100 are not involved, the air inlet of the air compressor 100 is not damaged, in addition, in the process of disassembling the filter cartridge 250, the filter cartridge 250 is removed from the fixing only after the clamping member 240 is rotated, and then the filter cartridge 250 can be disassembled conveniently, so that the operation is very convenient, and in addition, the filter cartridge 250 is fixed in a bolt-free manner, and can be directly disassembled and assembled by hand without using other tools.
Referring to fig. 4, 7 and 8, in one embodiment, the first clamping portion 221 is an annular groove formed on a side wall of the second end of the connecting rod 220, the second clamping portion 2411 is a clamping groove formed on a side wall of one end of the avoidance groove 241, and the clamping member 240 is operable to rotate to make the clamping groove approach or separate from the annular groove.
Specifically, when the clamping member 240 is manually operated to rotate so that the clamping groove of the clamping member 240 is turned into the annular groove of the connecting rod 220, the clamping member 240 is clamped by the groove wall clamped in the annular groove, so that the limiting body 230 is clamped by the clamping member 240; when the clamping member 240 is manually operated to rotate, so that the clamping groove of the clamping member 240 rotates out of the annular groove of the connecting rod 220, the connecting rod 220 is positioned in the avoidance groove 241, the connecting rod 220 and the clamping member 240 are in an unlocked state, and the clamping member 240 can be detached from the connecting rod 220.
More specifically, the clamping member 240 is a clamping plate, the avoidance groove 241 penetrates the clamping member 240, the avoidance groove 241 is an arc-shaped groove, the width of the avoidance groove 241 is larger than the diameter of the connecting rod 220, the inner diameter of the clamping groove is smaller than the diameter of the connecting rod 220, and the part of the connecting rod 220 provided with the annular groove can enter the clamping groove.
As shown in fig. 3 and 5, in one embodiment, the filtering device 200 further includes an elastic pressing member 260, where the elastic pressing member 260 is connected to the clamping member 240, and the elastic pressing member 260 is configured to apply a pressing force to the clamping member 240, so that the second clamping portion 2411 has potential energy to move toward the first clamping portion 221. In this way, during the use of the filtering apparatus 200, the elastic pressing member 260 can enable the second clamping portion 2411 to have potential energy moving toward the first clamping portion 221, so that the clamping member 240 maintains a state of being connected with the connecting rod 220, thereby avoiding loosening of the clamping member 240, and further avoiding reducing the filtering effect due to loosening of the filter cartridge 250.
Further, the elastic pressing member 260 is a torsion spring, a first end of the torsion spring is directly or indirectly connected with the limiting body 230, and a second end of the torsion spring is directly or indirectly connected with the clamping member 240. In the case where the second clamping portion 2411 is clamped with the first clamping portion 221, the torsion spring is in an initial state or a torsion state, wherein when the torsion spring is in the torsion state, the torsion spring can enable the second clamping portion 2411 to have potential energy moving toward the first clamping portion 221. When the clamping member 240 is manually rotated, the torsion spring slowly accumulates energy after the second clamping portion 2411 on the clamping member 240 is separated from the first clamping portion 221 on the connecting rod 220, and the second clamping portion 2411 has potential energy moving toward the first clamping portion 221.
Referring to fig. 5 and fig. 6, further, the clamping member 240 is provided with an avoidance hole 242, the filtering device 200 further includes an operation barrel 270, the operation barrel 270 is disposed through the avoidance hole 242 from a side of the clamping member 240 away from the limiting body 230 and is fixedly connected with a hole wall of the avoidance hole 242, the torsion spring is disposed in the operation barrel 270, and a second end of the torsion spring is connected with an inner wall of the operation barrel 270.

By arranging the bearing 280 on the limiting body 230 and fixedly connecting the outer ring of the bearing 280 with the limiting body 230, the operation cylinder 270 is more stable during rotation after the rotating shaft 271 penetrates through the inner ring of the bearing 280.
When the filter cartridge 250 is disassembled, the operator can manually twist the operating cylinder 270, so that the operating cylinder 270 drives the rotating shaft 271 and the clamping piece 240 to rotate together, and the second clamping piece 240 is separated from the first clamping piece 240. The operation cylinder 270 drives the rotation shaft 271 and the locking member 240 to rotate together, and also drives the torsion spring to twist.

In the above-described filter device 200, the attachment/detachment of the attachment base 210 to/from the air compressor 100 is not involved in the process of attaching/detaching the filter cartridge 250, and therefore, the air intake of the air compressor 100 is not damaged.
Specifically, the hollow screw is fixedly coupled to the side of the mounting base 210 remote from the filter cartridge 250.
In the air compressor assembly 10 described above with reference to fig. 1 to 4, the air may be filtered by the filter cartridge 250 in advance before entering the interior of the air compressor 100 through the air inlet of the air compressor 100. When the filter cartridge 250 needs to be replaced, only the clamping member 240 needs to be rotated, so that after the second clamping portion 2411 on the clamping member 240 is separated from the first clamping portion 221 on the connecting rod 220, the clamping member 240 and the limiting body 230 can be sequentially removed, and finally the filter cartridge 250 is removed, and the process of installing a new filter cartridge 250 is reversed with the above-mentioned removal process. In this way, in the above-mentioned filtering device 200, in the process of disassembling the filter cartridge 250, since the disassembly and assembly of the mounting base 210 and the air compressor 100 are not involved, the air inlet of the air compressor 100 is not damaged, in addition, in the process of disassembling the filter cartridge 250, the filter cartridge 250 is removed from the fixing only after the clamping member 240 is rotated, and then the filter cartridge 250 can be disassembled conveniently, so that the operation is very convenient, and in addition, the filter cartridge 250 is fixed in a bolt-free manner, and can be directly disassembled and assembled by hand without using other tools.
It should be noted that the first end of the filter cartridge 250 and the second end of the filter cartridge refer to opposite ends of the filter cartridge 250, and the first end of the connecting rod 220 and the second end of the connecting rod refer to opposite ends of the connecting rod 220.
