Vacuum cleaner and suction nozzle body thereof cross reference to related application

A vacuum cleaner comprising a vacuum cleaner main body, an electric blower motor provided in said vacuum cleaner main body, a dust collection part provided in said vacuum cleaner main body, a suction nozzle body for communicating with said dust collection part, an impeller having a rotary axis provided in an interior portion of said suction nozzle body and driven by a suction force which is generated by said electric blower motor, said suction nozzle body including at least one of a rotation brush member and a rotation blade member, an opening portion of said suction nozzle body being opposed to a surface to be subjected to cleaning, and a suction inlet port being provided for said suction nozzle body for sucking air from an outside portion independently of air sucked through said opening portion, said suction nozzle port being provided separately from said opening portion, said suction inlet port being provided so as to initially direct the air which is sucked from the outside portion in a direction transverse to the rotary axis of said impeller, and the air which initially impinges on said impeller and drives said impeller to rotate is thereafter sucked to said dust collection part through a space which is provided on said at least one of said rotation brush member and said rotation blade member.
