Suction cleaning tool with divided turbine chamber for fitting in suction cleaning appliance lets suction air stream enter brush chamber via suction slit through inflow aperture and flow out through a suction connection

摘要

A casing has brush and turbine chambers. The brush chamber has a brush roller whose bristles protrude through a suction slit. The turbine chamber has an air turbine for turning the brush roller's driving mechanism. A suction air stream (19) enters the brush chamber through the suction slit, passing through an inflow aperture (14) in an intermediate partition (13) between the brush and turbine chambers and flowing out through an aperture in a suction connection.
