Abstract:
1. A portable cyclonic vacuum cleaner comprising a cyclonic chamber formed of a conic body including a conic wall, a transverse upper wall closing off an upper end of said conic wall, a narrow nose at a lower end of the conic wall, a vortex tube penetrating said transverse wall and descending into said cyclonic chamber and serving as an outlet conduit for said flow of air from said cyclonic chamber, and an inlet conduit penetrating said conic wall below said transverse wall and adapted to introduce into said cyclonic chamber a flow of air in which dust particles are entrained, said air inlet conduit also being adapted to attach to a vacuum conduit; a dust collection drum positioned below said nose, having a drum lid closing off a top of the dust collection drum, the drum lid having a dust inlet opening at which the nose of the cyclonic chamber is coupled, so that dust separated from said flow of air in said cyclonic chamber falls into said dust collection drum; a filter chamber positioned in the flow of air after said cyclonic chamber, and including a housing, an inlet receiving air that exits the vortex tube of the cyclonic chamber; a motor plate that is mounted on said filter chamber housing and having a discharge opening therein; an air filter disposed in said filter housing, and being so disposed in said filter chamber such that the flow of air entering the inlet of the filter chamber passes through the filter media from one side thereof to another side thereof, and thence to the discharge opining in said motor plate; a vacuum blower supported on said motor plate and having a suction duct positioned on the discharge opening of said motor plate, to create said flow of air into said cyclonic chamber, and then into said filter chamber, through said filter media and out said discharge opening into said vacuum blower suction duct; and said motor plate includes a generally annular opening formed therein surrounding said discharge opening, and further comprising a pulse cleaning disk having a center opening slidably fitted on said suction duct, the disk lying atop said generally annular opening, and normally blocking flow of air therethrough; and a pulse-clean lift lever having an end portion attached to said disk and extending away from said suction duct to a handle portion thereof.
