Abstract
Abstract A dust collecting apparatus which is removably connected to a cleaner body is provided. The apparatus includes a cyclone body which forms a cyclone chamber and is in fluid communication with an air inlet passage on one side thereof; an exit pipe which is protruded from a bottom of the cyclone body to an upper side of the cyclone chamber; and a dust canister body which forms a dust collection chamber between the cyclone body and the dust canister body. The cyclone body is arranged eccentrically within the dust collection chamber so that a portion of the cyclone body has a common portion in contact with a portion of the dust canister body. The common portion is made of transparent materials to see through the cyclone chamber.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
199 words
A dust collecting apparatus for a vacuum cleaner which is removably mounted to a cleaner body, the apparatus comprising: an air inlet port through which external air entrained with dust is introduced; a cyclone body which forms a cyclone chamber wherein the external air is introduced through the air inlet port is made to whirl and the dust is separated therefrom, the cyclone body being formed transparently so that the cyclone chamber is visible therethrough; and a dust canister body which surrounds the cyclone body so as to form a dust collection chamber between the cyclone body and the dust canister body, and at least one portion of which is formed transparently so that the dust collection chamber is visible therethrough, wherein the cyclone body is arranged eccentrically with respect to the dust canister body, wherein the dust canister body has an exposure surface that is exposed to an outside of the cleaner body when the apparatus is mounted in the cleaner body, wherein the cyclone body and the dust canister body have a common portion which is an overlapping portion of the cyclone body and the dust canister body, and wherein the exposure surface includes the common portion.
