Dust collecting apparatus for cyclone type vacuum cleaner
First Claim
1. A dust collecting apparatus for a vacuum cleaner, comprising:
- a cyclonic chamber having an air inlet fluidly connected to a first conduit which is fluidly connected to a suction brush of a cleaner body, and a first air outlet, wherein the cyclone chamber is configured to impart a cyclonic spin on contaminant-laden air drawn through the air inlet;
a dust receptacle removably connected to the cyclonic chamber for receiving a contaminant which is thrown out from the spinning contaminant-laden air by centrifugal force;
a grill assembly disposed inside the cyclonic chamber and on an upstream side of the air outlet for preventing the thrown out contaminant from flowing backwards through the first air outlet; and
a filter assembly formed at an outer side of the cyclonic chamber for filtering out the contaminant being discharged to the air outlet, the filter assembly comprising;
a filter member,a filter frame receiving the filter member therein, and having a second air outlet corresponding to the first air outlet of the cyclonic chamber,and a third air outlet fluidly connected with a second conduit which is fluidly connected to an air driving source, anda cover removably connected to the filter.

Abstract
A dust collecting apparatus for a vacuum cleaner, which includes, a cyclonic chamber with an air inlet and a first outlet being formed therein, the cyclonic chamber causing air from the air inlet to spin therein, a dust receptacle connected to the cyclonic chamber, a grill assembly in the cyclonic chamber and on the upstream side of the air outlet to prevent dust and contaminants separated from the air from backflowing through the first air outlet, a main filter assembly connected to the grill assembly for filtering out dust and contaminants from the air backflowing from the grill assembly, and a supplementary filter assembly on the outside of the cyclonic chamber to re-filter the fine dust and contaminants incoming from the first air outlet. While conventional cyclone type vacuum cleaners are limited by the amount of contaminants that can be separated from the air, the disclosed vacuum cleaner can more effectively separate dust and contaminants.
