The cylinder 1 and the cylinder cover 101 are detachably connected by multiple bolts 102, and a motor 10 is detachably connected to the upper end of the cylinder cover 101. A rotating shaft 9 is fixedly connected to the output end of the motor 10, and the rotating shaft 9 is inserted into the interior of the cylinder 1, and a rotating drum 91 is fixedly connected to the outer side of the rotating shaft 9, an upper supporting plate 82 is fixedly connected to the upper end of the rotating drum 91, and a lower supporting plate 83 is fixedly connected to the lower end of the rotating drum 91, and multiple filter bags 8 are inserted and connected between the upper supporting plate 82 and the lower supporting plate 83, and filter tips 81 are threadedly connected to the upper ends of the filter bags 8.

[0020] Furthermore, the radius of the filter tip 81 is greater than the radius of the filter bag 8, and the filter tip 81 is threadedly connected to the upper support plate 82 to ensure that the filter bag 8 does not fall off.

[0021] Furthermore, the filter bags 8 pass through the upper support plate 82 and the lower support plate 83 to fix the position of the filter bags 8 .

[0022] Furthermore, the upper support plate 82 and the lower support plate 83 are attached to the cylinder 1 , so that the filter bag 8 rotates with the motor 10 and smoke is not discharged through the gap between the upper support plate 82 and the lower support plate 83 and the cylinder 1 .
