ELECTRIC CLEANER

摘要

The disclosed electric cleaner includes a filter drum produced by shaping a corrugated piece of fine filter sheet into a hollow, general circular cylinder, and a dusting unit disposed within the drum. The dusting unit includes one vibratile strip radially disposed in each wave on the corrugated piece and a coiled member rotatable about the longitudinal axis of the drum to successively flip the vibratile strips to vibrate the filter drum. Alternatively the dusting unit may include a beater movable along the filter axis to resiliently impart an impulse to the filter drum to vibrate it and a striker rotatable about the filter axis to strike the radially innermost portion of the drum.
