Cyclone-type dust collecting apparatus for vacuum cleaner |
摘要 |
Disclosed is a cyclone-type dust collecting apparatus for a vacuum cleaner. 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 the air from flowing back through the air outlet port; 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. And the cyclone body comprises a vortex current chamber formed with the air outlet port, a pressure drop chamber formed with the air outlet port, and also a path forming member for forming an air outlet guiding path by which the air containing the fine dust passing through the grill is flown from an upstream portion toward a downstream portion of the fine dust filtering means and then exhausted through the air outlet port, thereby preventing a backflow of the fine dust and increasing a dust collecting efficiency of the vacuum cleaner.
