[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] Working principle: When removing dust from the workshop air, the air is first introduced into the outer casing 1 through the air inlet pipe 2, then filtered by multiple filter bags 64, and finally discharged through the air outlet pipe 4. When replacing the filter bags 64, the operator first pushes the push plate 727, which moves the control plate 726. The control plate 726 moves the moving block 724 forward, which in turn rotates the inclined plate 721. The inclined plate 721 then raises the U-shaped block 719, which in turn raises the lifting block 76. The lifting block 76 raises the top block 72 on the fixed plate 73, which in turn raises the pressing plate 71. This facilitates the separation of the pressing plate 71 from the top ring 61, allowing the filter bags 64 to be easily removed from the frame 63. The operation is simple.

[0044] When the pressing plate 71 rises, the pressing plate 71 drives the lifting block 76 to rise, the lifting block 76 drives the connecting frame 711 to rise, and the connecting frame 711 drives the gear 716 on the mounting plate 712 to rise. When the gear 716 meshes with the toothed plate 717, the gear 716 continues to rise, causing the gear 716 to rotate. The gear 716 drives the screw 715 to rotate, the screw 715 drives the slider 714 to move, the slider 714 drives the rotating plate 2 710 to rotate, the rotating plate 2 710 drives the rotating plate 1 79 to rotate, the rotating plate 1 79 drives the rotating rod 78 to rotate, the rotating rod 78 drives the fixed plate 73 to rotate, the fixed plate 73 drives the top block 72 to rotate, and the top block 72 drives the pressing plate 71 to rotate, so that the pressing plate 71 and the upright plate 74 are arranged in parallel, making it convenient for the cloth bag 64 to be directly pulled out.
