[0015] Such as Figures 1-6As shown in the figure, a dust removal filter cartridge that prevents shedding includes a filter cartridge body 1 and a top plate 2 connected thereto. A sleeve 3 is fixedly connected to the center position at the bottom of the top plate 2. The top of the filter cartridge body 1 is an open structure, and the bottom is a sealed structure. A connecting pipe 4 is connected to the top of the filter cartridge body 1. The connecting pipe 4 is inserted into the inside of the sleeve 3. A fixing mechanism is provided on the connecting pipe 4 and the sleeve 3. The fixing mechanism includes through holes symmetrically distributed in the circumferential direction of the connecting pipe 4. A plurality of fixing rods 6 are symmetrically arranged on the outer circumference of the sleeve 3. The fixing rods 6 are horizontally arranged. One end of the fixing rod 6 extends inward through the sleeve 3. The other end of the fixing rod 6 is connected to a connecting plate 10. A first spring 7 is arranged between the connecting plate 10 and the sleeve 3. The first springs 7 are symmetrically arranged on both sides of the fixing rod 6. The positions of the fixing rods 6 correspond to the positions of the through holes one by one. A positioning mechanism is arranged between the sleeve 3 and the connecting pipe 4; specifically, the filter cartridge body 1 is installed at the bottom of the top plate 2. The installation process is to pull the two fixing rods 6 outwards, insert the connecting pipe 4 to the bottom inside the sleeve 3. After the positions of the fixing rods 6 correspond to the through holes, release the fixing rods 6, and the fixing rods 6 connect the connecting pipe and the sleeve 3, thereby preventing the filter cartridge from falling off.

[0016] One end of the first spring 7 is fixedly connected to the inner side surface of the connecting plate 10, and the other end of the first spring 7 is fixedly connected to the sleeve 3; through the connection of the first spring 7, the fixing rod 6 can be fixed, not easily lost, and will automatically return after being pulled outwards, which is convenient to use and convenient for disassembly and assembly.

[0017] The positioning mechanism includes a limiting protrusion 8 and a limiting groove 9 that cooperate with each other. The limiting protrusions 8 are symmetrically arranged on the outside of the circumferential direction of the connecting pipe 4, and the limiting grooves 9 are opened on the inner side of the circumferential direction of the sleeve 3; when installing, the through holes need to correspond to the positions of the fixing rods 6. Therefore, positioning is carried out through the limiting protrusion 8 and the limiting groove 9, and the installation is faster and more accurate.

[0018] The clamping structure includes grooves 11 symmetrically opened on the fixing rod 6. A second spring 12 is installed in the grooves 11. The end of the second spring 12 is fixedly connected to a clamping shaft 13, and the clamping shaft 13 expands and contracts along the grooves 11. Specifically, when the filter cartridge body 1 is not installed, the clamping structure fixes the fixing rod 6, and the clamping shaft 13 is stuck at the position of the sleeve 3, that is, the end of the fixing rod 6 does not enter the inside of the sleeve 3. In this way, the fixing rod 6 will not affect the insertion of the connecting pipe 4 into the sleeve 3 when installing the filter cartridge body 1. After the connecting pipe 4 is inserted into the sleeve 3, press the clamping shaft 23 to make the clamping shaft 23 retract, and the first spring 7 resumes deformation to insert the fixing rod 6 into the through hole, thereby fixing the filter cartridge body 1.
