[0036] The filter 6 is installed in the cage 3, and the filter 6 comprises a cloth bag 61 and a second fixing disc 62, the cloth bag 61 is fixed at the bottom of the second fixing disc 62, the second fixing disc 62 is installed with a limiting block 63, the limiting block 63 comprises a limiting connecting plate 631, a first limiting plate 632 and a second limiting plate 633, the limiting connecting plate 631 is vertically installed at the bottom of the second fixing disc 62, the first limiting plate 632 is horizontally installed at the connecting position of the limiting connecting plate 631 and the second fixing disc 62, and the second limiting plate 633 is horizontally installed at the bottom of the limiting connecting plate 631.

[0037] During installation, the filter 6 is inserted into the limiting slot 311 of the cage 3 through the limiting block 63, the second limiting plate 633 is clamped below the clamping plate 312, and the first limiting plate 632 abuts above the clamping plate, so that quick locking and anti-falling are realized.

[0038] The fan 9 is installed at the bottom of the sedimentation cavity 23, and is used for blowing the smoke dust entering from the feeding pipe 231 upward to achieve the filtering purpose.
