Abstract

The hand-held cleaner includes a body, and a cyclone dust collecting apparatus detachably mounted in the body. The cyclone dust collecting apparatus includes a pre-motor filter unit having a filter grill and a filter member, a dust collecting bin having one end to which the pre-motor filter unit is coupled and the other end opposite to the one end in which an cyclone inlet is formed, and a cyclone bin disposed in the dust collecting bin and having a spiral flow path-guide member integrally formed therein. A moving path of air drawn into the cyclone inlet is maintained in the same direction until the air is discharged through the pre-motor filter unit via the cyclone bin.

Claims

1. A cyclone dust collecting apparatus comprising:

a pre-motor filter unit having a filter grill and a filter member;

a dust collecting bin having one end to which the pre-motor filter unit is coupled and the other end opposite to the one end in which an cyclone inlet is formed; and

a cyclone bin disposed in the dust collecting bin and having a spiral flow path-guide member integrally formed therein,

wherein a moving path of air drawn into the cyclone inlet is maintained in the same direction until the air is discharged through the pre-motor filter unit via the cyclone bin.

2. The apparatus as claimed in claim 1, wherein the dust collecting bin further comprises an anti-back flow rib extended from the cyclone inlet toward the pre-motor filter unit.

3. The apparatus as claimed in claim 1, wherein the pre-motor filter unit is coupled to an upper end of the dust collecting bin, and the cyclone inlet is formed in a lower end of the dust collecting bin.

4. The apparatus as claimed in claim 1, wherein the pre-motor filter unit comprises an upper casing and a lower casing, the filter member is mounted between the upper casing and the lower casing, and the filter grill is convexly projected from the lower casing.

5. A hand-held cleaner comprising:

a body; and

a cyclone dust collecting apparatus detachably mounted in the body,

wherein the cyclone dust collecting apparatus comprises

a pre-motor filter unit having a filter grill and a filter member;

a dust collecting bin having one end to which the pre-motor filter unit is coupled and the other end opposite to the one end in which an cyclone inlet is formed; and

a cyclone bin disposed in the dust collecting bin and having a spiral flow path-guide member integrally formed therein, and

wherein a moving path of air drawn into the cyclone inlet is maintained in the same direction and not changed until the air is discharged through the pre-motor filter unit via the cyclone bin.

6. The cleaner as claimed in claim 5, wherein the body comprises a cyclone mounting space to accommodate the cyclone dust collecting apparatus, a vacuum source provided on one side of the cyclone mounting space, and a cleaner inlet port provided on the other side of the cyclone mounting space to communicate with the cyclone inlet.

7. The cleaner as claimed in claim 6, wherein the body further comprises a rib formed on and projected from the cleaner inlet port.

8. The cleaner as claimed in claim 6, wherein the body further comprises a roller disposed on a lower end of the cleaner inlet port to rotate while being in contact with a surface to be cleaned thereby to allow the hand-held cleaner to be easily moved back and forth.

9. A stick cleaner comprising:

a stick body comprising a handle provided on an upper part thereof and a central part in the form of a jar provided on a lower part thereof;

a nozzle assembly rotatably coupled to a lower end of the stick body;

a mounting space formed in the central part;

an inner air passage connecting the nozzle assembly and the mounting space; and

a hand-held cleaner detachably mounted in the mounting space to provide suction force to the nozzle assembly through the inner air passage,

wherein the hand-held cleaner comprises

a body; and

a cyclone dust collecting apparatus detachably mounted in the body,

wherein the cyclone dust collecting apparatus comprises

a pre-motor filter unit having a filter grill and a filter member;

a dust collecting bin having one end to which the pre-motor filter unit is coupled and the other end opposite to the one end in which an cyclone inlet is formed; and

a cyclone bin disposed in the dust collecting bin and having a spiral flow path-guide member integrally formed therein, and

wherein a moving path of air drawn into the cyclone inlet is maintained in the same direction and not changed until the air is discharged through the pre-motor filter unit via the cyclone bin.

10. The stick cleaner as claimed in claim 9, wherein the body comprises a cyclone mounting space to accommodate the cyclone dust collecting apparatus, a vacuum source provided on one side of the cyclone mounting space, and a cleaner inlet port provided on the other side of the cyclone mounting space to communicate with the cyclone inlet.

11. The cleaner as claimed in claim 10, wherein the body further comprises a rib formed on and projected from the cleaner inlet port.
