When the fan assembly 5 starts to work, dust-containing gas enters the cyclone separation assembly 3 through the brush head 1 and the suction pipeline 2, and the airflow moves from top to bottom in a spiral shape along the inner wall of the cyclone separation assembly 3 to form descending outward-rotating dust-containing airflow. The centrifugal force generated during the strong rotation throws dust particles having a density much higher than that of the gas towards the inner wall, and the dust particles fall down along the inner wall into the dust cup 4 after contacting the inner wall. After reaching the bottom, the rotating and descending airflow turns upwards along the axis of the cyclone separation assembly 3 to form ascending internal rotation airflow, and then the ascending internal rotation airflow is discharged from the exhaust port of the cyclone separation assembly 3. By means of the cyclone assembly 3, the dust collecting apparatus of the present application effectively separates gas and solids, and the solid waste is collected in the dust cup 4.
