Abstract
A cyclone dust collecting device for a vacuum cleaner includes a cyclone body and a cyclone housing for separating the contaminants from the air. The cyclone housing includes a cyclone cover and a dust collecting container. The cyclone cover has a cylindrical shape, one end of which is coupled to the cyclone body. The other end is a slanted end with a through-hole formed therein and a centrally located dome-shaped protrusion. The dust collecting container also has a slanted end, which is detachably engaged with the slanted end of the cyclone cover. The other end of the dust collecting container is tapered to correspond with the slanted end of the cyclone cover. The slanted end of the cyclone cover protects a grill in the cyclone dust collecting device during operation and removal of contaminants from the dust collecting container.
