ABSTRACT:
A cyclone dust collecting device, for use in a vacuum cleaner, includes a housing defining therein a cyclonic air flow chamber. A dust collection chamber is disposed under the cyclonic air flow chamber and a partition wall is disposed between the cyclonic air flow chamber and the dust collection chamber. An opening and at least one ventilation hole are provided in opposite sides of the partition wall, respectively, so that a part of air and dust vortically moving in the cyclonic air flow chamber are introduced into the dust collection chamber through the opening and the air in the dust collection chamber flows back into the cyclonic air flow chamber through the ventilation hole.
