Patent ID: 7678166

Claim:
A cyclone dust collecting apparatus for a vacuum cleaner comprising: a first cyclone having an air suction hole through which dust-laden air is drawn-in, the first cyclone forcing the dust-laden air to form a first downwardly whirling air current in a space under the air suction hole so as to centrifugally separate dust from the dust-laden air; a second cyclone disposed inside the first cyclone, the second cyclone forcing semi-clean air entering from the first cyclone to form a second downwardly whirling air current so as to centrifugally separate fine dust from the semi-clean air; and an air guiding member forcing the semi-clean air discharged from the first cyclone to directly enter the second cyclone and, the air guiding member having a plurality of guiding blades radially disposed in at least one circular shape based on a vertical axis of the second cyclone, wherein the plurality of guiding blades forms a plurality of slots to simultaneously function as an air discharging opening of the first cyclone and an air entering opening of the second cyclone, wherein the plurality of guiding blades are disposed about a base, wherein the base comprises an inclined surface that assists in forming the first downwardly whirling air current.
