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

1. A dust collecting apparatus which is removably mountable to a cleaner body, comprising:

a cyclone body which forms a cyclone chamber in fluid communication with an air inlet passage on one side thereof;

an exit pipe protruding from a bottom of the cyclone body to an upper side of the cyclone chamber; and

a dust canister body which has an exposure surface that is exposed to an outside of the cleaner body upon mounting in the cleaner body, the dust canister body surrounding the cyclone body so as to form a dust collection chamber between the cyclone body and the dust canister body,

wherein 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 exposure surface, and wherein at least the common portion is made of transparent materials to see through the cyclone chamber.

2. The apparatus as claimed in claim 1, wherein all of the cyclone body is made of transparent materials.

3. The apparatus as claimed in claim 1, wherein the cyclone body comprises a plurality of cyclone bodies.

4. The apparatus as claimed in claim 1, wherein the cyclone chamber further comprises a helical guide for enhancing a rotating force of air flowing into the air inlet port, and wherein the helical guide is colored lighter than the cyclone body so as to facilitate ascertaining whether dirt is flowing in the cyclone body.

5. A dust collecting apparatus which is removably mountable to a cleaner body, comprising:

a cyclone body which forms a cyclone chamber in fluid communication with an air inlet passage on one side thereof;

an exit pipe protruding from a bottom of the cyclone body to an upper side of the cyclone chamber; and

a dust canister body which has an exposure surface that is exposed to an outside of the cleaner body upon mounting in the cleaner body, the dust canister body surrounding the cyclone body so as to form a dust collection chamber between the cyclone body and the dust canister body,

wherein the cyclone body is arranged eccentrically within the dust collection chamber so that the cyclone body has a protruded portion protruding from the exposure surface, and wherein at least the protruded portion is made of transparent materials in order to see through the cyclone chamber.

6. The apparatus as claimed in claim 5, wherein all of the cyclone body is made of transparent materials.

7. The apparatus as claimed in claim 5, wherein the cyclone body comprises a plurality of cyclone bodies.

8. The apparatus as claimed in claim 5, wherein the cyclone chamber further comprises a helical guide for enhancing a rotating force of air flowing into the air inlet port, and wherein the helical guide is colored lighter than the cyclone body so as to facilitate ascertaining whether dirt is flowing in the cyclone body.

9. A dust collecting apparatus which is removably mountable to a cleaner body, comprising:

a cyclone body which forms a cyclone chamber in fluid communication with an air inlet passage on one side thereof;

an exit pipe protruding from a bottom of the cyclone body to an upper side of the cyclone chamber; and

a dust canister body which has an exposure surface that is exposed to an outside of the cleaner body upon mounting in the cleaner body, the dust canister body surrounding the cyclone body so as to form a dust collection chamber between the cyclone body and the dust canister body,

wherein the cyclone body is arranged eccentrically within the dust collection chamber.

10. The apparatus as claimed in claim 9, wherein the cyclone body comprises a plurality of cyclone bodies.

11. The apparatus as claimed in claim 9, wherein the cyclone chamber further comprises a helical guide for enhancing a rotating force of air flowing into the air inlet port, and wherein the helical guide is colored lighter than the cyclone body in order to facilitate ascertaining whether dirt is flowing into the cyclone body.
