ABSTRACT:
Disclosed is a cyclone-type dust collecting apparatus for a vacuum cleaner, that includes 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 double grill assembly disposed at an upstream portion of the air outlet port in the cyclone body to prevent the air from flowing back through the air outlet port, and having a dual structure having an outer grill and an inner grill, and a fine dust collecting means disposed at a downstream portion of the double grill assembly in the cyclone body to collect fine dust which is not removed by the double grill assembly.
