Cyclonic dust-collecting apparatus with noise-reducing member

摘要

A cyclonic dust-collecting apparatus (200) has a cyclone body (240) having an inlet passage (245) formed therein. An upper cover (210) is disposed on an upper portion of the cyclone body (240), and a dust receptacle (280) is disposed under the cyclone body. A noise-reducing member (300) nests in the cyclone body (240) in contact with an inner surface of the cyclone body, whereby dust-carrying air flowing through the inlet passage (245) collides with the noise-reducing member so that noise can be reduced. The noise-reducing member may be constructed from porous plastic, sponge or urethane.
