Cyclonic dust collecting apparatus with means for reducing inlet pressure loss

摘要

A dust separating apparatus (100) for a vacuum cleaner includes a dust collection casing (200) with an air inlet (205) at a lower portion (209), a mesh filter (221) formed on a bottom surface of the dust collection casing to firstly filter the contaminant from the drawn-in air, a plurality of cyclones (230,240) formed in parallel in the dust collection casing to secondly filter the contaminant in the air drawn in via the air inlet, and a dust collection part (250) formed at one side of the plurality of cyclones to collect the contaminant separated from the air. The air flowed in the air inlet formed at the lower portion of the dust collection casing is sequentially discharged via the mesh filter (221) formed on the bottom surface of the dust collection casing and the plurality of cyclones (230,240).
