ABSTRACT:
A cyclone-type dust collecting apparatus for a vacuum cleaner having a dual contaminant separating structure in which contaminants can be effectively separated and collected comprising a cyclone body having a dual structure including a first outer cylinder and a first inner cylinder with the lower part open, and an air inlet portion and an air discharge portion connected to an upper surface of the body portion in an area of an upper surface of the inner cylinder for air, including entrained contaminants, to flow in through the air inlet portion to form a cyclone stream, a first contaminant discharge path formed on the lower side of the first inner cylinder for discharging contaminants to a space between the first inner cylinder and the first outer cylinder, a contaminant collecting receptacle having an inner space divided into a first contaminant collecting space and a second contaminant collecting space by the dual structure of a second outer cylinder corresponding to the first outer cylinder and a second inner cylinder corresponding to the first inner cylinder, the contaminant collecting receptacle having at least one second contaminant discharge path formed on the lower side of the second inner cylinder, and a grill mounted at the beginning of the air discharge portion inside the cyclone body for preventing the contaminants separated from air from reversing through the air discharge portion.
