ABSTRACT:
A cyclone-type dust collecting apparatus for a vacuum cleaner is provided. The apparatus comprises a cyclone body having an air inlet port and an air outlet port, for forming a vortex current of air which is introduced through the air inlet port and contains dust; a dust collecting container removably coupled to the cyclone body so as to collect the dust separated by centrifugal force of the vortex current in the cyclone body; a grill disposed at an upstream portion of the air outlet port in the cyclone body to prevent dust separated from the air from flowing back through the air outlet part; and a fine dust filtering means disposed at a downstream portion of the grill in the cyclone body to collect fine dust which passes through the grill.
