Abstract
A dust collector includes a cylindrical housing forming an outer appearance of the dust collector; a cyclone formed inside the housing to cause a swirling flow to separate dust from air introduced into the housing; axial inlet type swirl tubes to receive air and fine dust that have passed through the cyclone, and causing a swirling flow to separate the fine dust from the air; and a mesh configured to surround an outside of the axial inlet type swirl tubes to form a boundary between the cyclone and the axial inlet type swirl tubes, wherein the axial inlet type swirl tubes are configured with four groups and stacked in multiple stages on virtual quadrants, the axial inlet type swirl tubes arranged in the same quadrant are arranged to face the same direction, and the axial inlet type swirl tubes arranged in different quadrants are arranged to face different directions.
