[0019] 2. During the filtration of exhaust gas, the motor drives the screw to rotate. The rotation of the screw causes the threaded tube to move up and down relative to the screw. The threaded tube drives the air outlet box to move up and down. The air blown out from the air outlet changes position on the bottom side of the filter bag. As the airflow changes the position of the filter bag, it causes the filter bag to shake. At the same time, the air blown into the filter bag will be blown out from other parts of the filter bag, which can also blow away the dust on the filter bag. This can shake off the dust on the filter bag and prevent the filter bag from clogging.

[0020] 3. The fixed tube has an annular groove inside, and a sealing ring is installed inside the annular groove. The sealing ring can ensure the sealing between the threaded tube and the fixed tube, and prevent a large amount of dust inside the box from falling on the screw, so as to avoid affecting the normal fit between the screw and the threaded tube.
