[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0023] See also Figure 1 and Figure 2 A dust filter cartridge includes a cylindrical filter cloth 1, a top retaining ring 2 and a bottom retaining ring 3 respectively fixed to the top and bottom of the filter cloth 1, and an outer retaining net 4 sleeved on the outside of the filter cloth 1, and the top and bottom of the outer retaining net 4 are respectively fixedly connected to the top retaining ring 2 and the bottom retaining ring 3. By sleeved the outer retaining net 4 on the outside of the filter cloth 1, and the top and bottom of the outer retaining net 4 are respectively fixedly connected to the top retaining ring 2 and the bottom retaining ring 3, the filter cloth 1 is confined in the outer retaining net 4, the filter cloth 1 is further fixed, and does not affect the flow of gas, does not affect the filtering effect, the structure is more stable, can withstand strong air flow, and has a longer service life.

[0024] The filter cloth 1 is folded to form a plurality of folds, which can not only make the filter cloth 1 more solid, but also increase the filtering area and enhance the filtering effect.

[0025] The top surface of the top retaining ring 2 is provided with an upwardly protruding elastic ring 5. The elastic ring 5 can be sealed when the dust removal filter cartridge is installed on the air purification device.

[0026] The vertical cross section of the elastic ring 5 is narrow at the top and wide at the bottom, so that the top of the elastic ring 5 can provide better elastic deformation and the bottom of the elastic ring 5 can provide better bearing capacity.

[0027] The inner edge and outer edge of the top retaining ring 2 extend downward to form a top inner ring 21 and a top outer ring 22 respectively sleeved inside and outside the filter cloth 1. The top inner ring 21 and the top outer ring 22 can further protect the top edge of the filter cloth 1.

[0028] The inner edge and outer edge of the bottom retaining ring 3 extend upward to form a bottom inner ring 31 and a bottom outer ring 32 respectively sleeved inside and outside the filter cloth 1. The bottom inner ring 31 and the bottom outer ring 32 can further protect the bottom edge of the filter cloth 1.

[0029] It also includes an inner retaining net 6 sleeved on the inner side of the filter cloth 1, and the top and bottom of the inner retaining net 6 are respectively fixedly connected to the top retaining ring 2 and the bottom retaining ring 3. The inner retaining net 6 further limits and reinforces the inner structure of the filter cloth 1, and further enhances the structural stability of the filter cloth 1.

[0030] The inner side of the filter cloth 1 is bonded to the inner barrier net 6 by a plurality of annular adhesives 7 arranged up and down. In this way, the inner structure of the filter cloth 1 can be further positioned and reinforced, and the structural stability of the filter cloth 1 can be further enhanced.

[0031] The inner barrier net 6 and the outer barrier net 4 are made of metal, which is more durable and firm.

[0032] The top and bottom of the inner baffle 6 are respectively welded to the top baffle ring 2 and the bottom baffle ring 3, and the top and bottom of the outer baffle 4 are respectively welded to the top baffle ring 2 and the bottom baffle ring 3. This can be more secure.
