Patent

CA 2387271

A cyclone dust-collecting apparatus for a vacuum cleaner capable of improving the dust-collecting function of the vacuum cleaner by preventing filth, which has not been separated from the air current at the stage of a whirling air current, from being flown to a vacuum- generating device of the vacuum cleaner. The cyclone dust-collecting apparatus for a vacuum cleaner comprises a cyclone body for separating filth from drawn air through an air-suction passage and discharging the cleaned air through an air-discharging passage, a filth backflow preventing member that shifts the advancing direction of the filth included in the air, which flows to the air-discharging passage, to a whirling air current that whirls along an inner side of the cyclone body.
