ABSTRACT:
A cyclone dust collecting apparatus for a canister type vacuum cleaner has a connection pipe connected to a suction brush, a cyclone body, and a dust collecting receptacle provided in the cyclone body. The dust collecting receptacle is positioned alongside the connection pipe, and the contacting side of the connection pipe is contoured to correspond to the shape of the outer contour of the dust collecting apparatus. The mating contact of the connection pipe and the dust collecting receptacle reduces the overall thickness of their coextensive lengths and provides a secure connection therebetween. The resulting compact configuration enables a user to use or carry the cyclone dust collecting apparatus more conveniently.
