[0019] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of 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.

[0020] Embodiment 1

[0021] See also Figure 1-Figure 4The utility model provides a technical solution: a dust filter cartridge bottom anti-slipping device, the dust filter cartridge bottom anti-slipping device comprises: a dust filter cartridge body 1, a fixing strap 2 and a top cover 3, the surface of the dust filter cartridge body 1 is provided with a fixing strap 2, the top of the dust filter cartridge body 1 is provided with a top cover 3, the bottom of the dust filter cartridge body 1 is provided with an anti-slipping cover 4, both sides of the anti-slipping cover 4 are penetrated and connected with locking rods 5, the anti-slipping cover 4 is slidably connected with a slider 6 on the side close to the locking rod 5, the slider 6 and the locking rod 5 are rotatably connected with a connecting rod 7 through a rotating shaft, a push rod 8 is welded to the bottom of the slider 6, and a first spring 9 is welded to one side of the push rod 8 and the anti-slipping cover 4.

[0022] Embodiment 2

[0023] On the basis of Example 1, when the dust filter cartridge is in use, it is usually easy to cause the filter to fall off from the bottom. By pushing the push rod 8, the push rod 8 can push the connected slider 6 when moving, so that the slider 6 can slide on the surface of the anti-detachment cover 4. At the same time, the push rod 8 can squeeze the first spring 9 when moving. Secondly, the slider 6 can push the connecting rod 7 connected to the surface when moving, so that the connecting rod 7 can push the locking rod 5 when moving, and then the locking rod 5 can move inside the anti-detachment cover 4, so that the locking rod 5 can be separated from the dust filter cartridge body 1, so that the anti-detachment device at the bottom of the dust filter cartridge can prevent the internal filter from falling off when in use.
