Dust-separating apparatus for a vacuum cleaner

摘要

The dust-separating apparatus (100) includes an air inlet (111) formed in an upper surface of the dust-separating apparatus, and an inlet pipe (112) coupled to the air inlet for guiding dust-carrying air downwardly into the dust-separating apparatus. The far end of the inlet pipe (112) opens just above the bottom surface (120a) of the dust-separating apparatus (100) where dust particles collide with that surface. An air outlet (113) is formed in a sidewall of the dust-separating apparatus (100). One or more guide members (131, 132) formed inside the dust-separating apparatus (100) prevent dust from flowing upwardly, and provide surfaces against which air-borne particles can collide. A removable dust collection receptacle (120) stores collected dust. In a preferred embodiment a filter (150, fig 6) is added to the bottom of the inlet pipe (112).
