[0024] When the dust collector is used, the pulse mechanism 13 is used to clean the dust attached to the dust bag 41. The pulse mechanism 13 can be used to flow air from top to bottom so that the air flow can act on the position of the top ring 3, so that the winding rods 8 inside the top ring 3 and the bottom ring 7 can rotate at the same speed and in the same direction, so that the winding rod 8 can reel the pulling rope 81, so that the dust ring 5 is pulled by the pulling rope 81 to slide downward on the outside of the dust bag 41. At the same time, the dust ring 5 slides on the outside of the limit rod 6, so that the dust ring 5 can move the dust bag 4 1 is brushed downward to improve the efficiency of the pulse dust collector in cleaning the dust bag 41. When the dust ring 5 drops to the bottom position and contacts the bottom ring 7, it stops dropping. When the dust collector is used for filtering, the filtered airflow flows from bottom to top, so that the airflow passes through the dust bag 41 and moves toward the top of the top ring 3, thereby driving the winding rod 8 to rotate in the opposite direction. Then, the dust ring 5 can be pulled upward to the initial position by the pulling rope 81, and stops moving upward after the dust ring 5 moves to contact the bottom end of the top ring 3.

When the airflow filtered by the dust bag 41 flows toward the position of the top ring 3, the upward airflow can be guided to the position of the guide fan 62 through the guide plate 31, so that the dust removal ring 5 can be affected by the upward airflow through the guide fan 62 and move upward to the initial position.
