Cyclone dust collecting device for a vacuum cleaner
First Claim
1. A cyclone dust collecting device for a vacuum cleaner, comprising:
- a cyclone body for connection to a telescopic extension pipe of the vacuum cleaner, the cyclone body generating a swirling vortex from an inflow of air and contaminants; and
a cyclone housing detachably engaged with the cyclone body, the cyclone housing having a slanted partition with a through-hole formed therein, the slanted partition dividing an interior of the cyclone housing into an upper space for separating the contaminants from the air by guiding the swirling vortex of air and a lower space for receiving the contaminants that have been separated from the air, and a cyclone cover having a cylindrical shape, an open upper end, a lower closed end disposed at a lower portion of the cyclone cover, the open upper end being engaged with the cyclone body, the lower closed end being closed by the slanted partition, and a dust collecting container detachably engaged with the lower portion of the cyclone cover, the dust collecting container having an open end that is slanted to correspond with the slanted partition of the cyclone cover.

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.
