[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figures 1 to 4 As shown, an air filter for quick replacement of filter elements described in an embodiment of the present invention comprises an air filter body 1; a mounting groove 21 is provided inside the air filter body 1; an air filter outer cover 2 is fixedly connected to the top of the air filter body 1; a filter element outer cover 3 is detachably fixedly connected to the air filter outer cover 2 by bolts; a filter element box 4 is fixedly connected to the side wall of the filter element outer cover 3; a filter cloth 5 is fixedly connected to the inside of the filter element box 4; the filter element box 4 and the mounting groove 21 are slidably fitted together. When working, the conventional air filter outer cover 2 is processed into an integral part of the air filter outer cover 2 and the air filter body 1 by welding during production. When installing, pick up the filter element outer cover 3, align the filter element box 4 with the position of the installation groove 21, insert the filter element box 4 into the installation groove 21, and then fix the filter element outer cover 3 on the air filter outer cover 2 with bolts. At this time, filtering is carried out through the filter cloth 5 inside the filter element box 4. When the filter cloth 5 needs to be replaced after long-term use, the filter element box 4 can be directly taken out for replacement by directly removing the bolts used to connect the air filter outer cover 2 and the filter element outer cover 3. By directly welding the inner and outer covers into an integrated form during production, it is only necessary to remove the bolts to take out the filter element as a whole when in use, which optimizes the air filter assembly process and is more convenient and quick.

[0027] like Figures 1 to 7 As shown, a pair of empty slots 6 are provided on the bottom side walls of the filter cartridge box 4; springs 7 are fixedly connected inside the empty slots 6; the springs 7 are provided in multiple groups and are arranged in an array; a top plate 8 is fixedly connected to the end of the spring 7; the top plate 8 is located inside the empty slots 6 and is slidably connected between the empty slots 6. During operation, when the filter cartridge box 4 is installed inside the mounting groove 21, the top plate 8 is squeezed by the inner wall of the mounting groove 21 so as to extend into the empty slot 6. At this time, under the elastic action of the spring 7, the top plate 8 generates a reverse thrust force on the filter cartridge box 4. When the filter cartridge outer cover 3 is disassembled and separated, the reverse thrust force causes the filter cartridge box 4 to drive the filter cartridge outer cover 3 to pop up, so that the filter cartridge and the air filter are quickly separated, thereby making it more convenient to remove the filter cartridge.

[0028] like Figure 5As shown, the side wall of the filter element outer cover 3 is provided with multiple groups of grooves 9; the grooves 9 are arranged in an array on the filter element outer cover 3. During operation, by providing the grooves 9 on the surface of the filter element outer cover 3, the user can insert his fingers into the grooves 9 and pinch the inner wall of the grooves 9 to lift the filter element box 4 out of the installation slot 21, which is more convenient.

[0029] like Figure 5 As shown, the inner wall of the groove 9 is fixed with an anti-slip pad 10; the anti-slip pad 10 is arranged around the groove 9. When working, the anti-slip pad 10 is provided on the groove 9, which can increase the friction on the user's hand and reduce the possibility of slipping.

[0030] like Figure 6 As shown, a sealing gasket 11 is fixed to the bottom side wall of the filter element outer cover 3; the sealing gasket 11 is sleeved on the filter element box 4. During operation, by providing the sealing gasket 11 on the filter element outer cover 3, when the filter element outer cover 3 is installed, the sealing gasket 11 seals the connection between the filter element outer cover 3 and the air filter outer cover 2, thereby reducing the entry of external dust and improving the sealing effect.

[0031] like Figure 6 As shown, the inner wall of the filter cartridge box 4 is fixed with multiple groups of pads 12; the pads 12 and the filter cloth 5 are staggered. During operation, the pads 12 are staggered on the filter cartridge box 4, so that the pads 12 can lift the filter cloth 5, thereby reducing the problem that the dust accumulated on the filter cloth 5 will bend the filter cloth 5 due to gravity during the process of removing the filter cartridge box 4, thereby reducing the problem of dust residue inside the installation groove 21.

[0032] Working principle: During the production of the conventional air filter outer cover 2, the air filter outer cover 2 and the air filter body 1 are processed into one piece using a welding process. During installation, pick up the filter element outer cover 3, align the filter element box 4 with the position of the installation slot 21, insert the filter element box 4 into the installation slot 21, and then fix the filter element outer cover 3 on the air filter outer cover 2 with bolts. At this time, filtering is performed through the filter cloth 5 inside the filter element box 4. When the filter cloth 5 needs to be replaced after long-term use, the filter element box 4 can be directly taken out for replacement by directly removing the bolts used to connect the air filter outer cover 2 and the filter element outer cover 3. By directly welding the inner and outer covers into one piece during production, it is only necessary to remove the bolts to take out the filter element as a whole during use, which optimizes the air filter assembly process and is more convenient and quick.

[0033] When the filter element box 4 is installed in the installation groove 21, the top plate 8 is squeezed by the inner wall of the installation groove 21 to extend into the empty groove 6. At this time, under the elastic action of the spring 7, the top plate 8 generates a reverse thrust force on the filter element box 4. When the filter element outer cover 3 is disassembled and separated, the filter element box 4 is subjected to the reverse thrust force, and the filter element outer cover 3 is popped up by the filter element box 4, so that the filter element and the air filter are quickly separated, making it easier to remove the filter element.

[0034] By opening a groove 9 on the surface of the filter element outer cover 3, the user can insert his fingers into the groove 9 and pinch the inner wall of the groove 9 to lift the filter element box 4 out of the installation groove 21, which is more convenient.

[0035] By providing the anti-slip pad 10 on the groove 9, the friction force on the user's hand can be increased, thereby reducing the possibility of slipping.

[0036] By providing a sealing gasket 11 on the filter element outer cover 3, when the filter element outer cover 3 is installed, the sealing gasket 11 seals the connection between the filter element outer cover 3 and the air filter outer cover 2, reducing the entry of external dust and improving the sealing effect.

[0037] By staggering the pads 12 on the filter cartridge box 4, the pads 12 can lift the filter cloth 5, thereby reducing the problem of dust accumulated on the filter cloth 5 being bent by gravity during the removal of the filter cartridge box 4, thereby reducing the problem of dust residue inside the installation groove 21.

[0038] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
