Abstract
A dust collection device for use with a power tool includes a housing, an air inlet pipe, a cyclone pipe, an air duct pipe, and a ventilation pipe. The air inlet pipe is configured to guide an airflow to enter the dust collection device along a first straight line. The cyclone pipe extends along the second straight line. The cyclone pipe has a first end for air intake and a second end for dust discharge. The ventilation pipe is arranged at the first end and communicated with the cyclone pipe and is configured to guide the airflow after the airflow is subjected to dust separation performed by the cyclone pipe out of the housing. The second straight line along which the cyclone pipe extends intersects the first straight line to form an angle greater than or equal to 25° and less than or equal to 90°.
