[0032] The implementation principle of this utility model is as follows: When using the filter bag 2, first place the bottom of the filter bag 2 on the support plate 31, so that the fixing block 32 passes through the top of the filter bag 2. Then push the movable plate 35 to compress the spring 36, so that the insert plate 37 is removed from the fixing block 32 and the insert block 33. Insert the insert block 33 into the slot 10 at the bottom of the clamping plate 34. Release the movable plate 35, the spring 36 returns to its original position, and the insert plate 37 is inserted into the fixing block 32 and the insert block 33, locking the insert block 33 and fixing the top of the filter bag 2 to the clamping plate 34. Next, insert the clamping plate 41 into the fixing frame 1. The clamping block 42 pops out under the action of the return spring 44 and snaps in. The filter bag 2 is installed in the snap-fit ​​groove 43 on the inner wall of the fixing frame 1. When disassembling, press the movable block 45. The movable block 45 drives the snap-fit ​​block 42 to compress the return spring 44, so that the snap-fit ​​block 42 exits the snap-fit ​​groove 43. Then the snap-fit ​​plate 41 can be taken out from the fixing frame 1. Then push the movable plate 35 to make the insert plate 37 exit the fixing block 32 and the insert block 33. Pull out the insert block 33 to remove the filter bag 2. Throughout the process, the anti-slip texture ensures the stability of the fixing frame 1, the auxiliary block 6 and the handle 7 facilitate operation, and the telescopic block 8 and the movable groove 9 ensure the reliable operation of the installation mechanism, realizing the anti-detachment fixing and convenient installation and disassembly of the filter bag 2.

[0033] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
