Abstract

A suction brush of a vacuum cleaner includes: a body configured to communicate with a dust collection device and including at least one suction port; a cover configured to cover a top of the body; and at least one rolling pin configured to be rotatably coupled at a bottom of the body.

Claims

1. A suction brush of a vacuum cleaner, comprising:

a body configured to communicate with a dust collection device and including at least one suction port;

a cover configured to cover a top of the body; and

at least one rolling pin configured to be rotatably coupled at a bottom of the body.

2. The suction brush of claim 1, wherein the at least one rolling pin includes a first rolling pin installed at a first side of the body and a second rolling pin installed a second side of the body.

3. The suction brush of claim 2, wherein the first side is opposite the second side.

4. The suction brush of claim 2, wherein at least one dust guide groove is configured to be formed at the bottom of the body to guide debris and air to the at least one suction port.

5. The suction brush of claim 4, wherein the first and second rolling pins are respectively installed proximate to opposite ends of the at least one dust guide groove.

6. The suction brush of claim 1, wherein the at least one rolling pin comprises:

a cylindrical portion configured to contact a surface to be cleaned, thereby spacing the bottom of the body from the surface to be cleaned; and

at least one coupling projection configured to project from opposite ends of the cylindrical portion and configured to be rotatably connected to the bottom of the body.

7. The suction brush of claim 1, wherein the at least one rolling pin comprises a groove formed along the periphery thereof.

8. The suction brush of claim 7, wherein the groove includes at least one spiral portion.

9. A vacuum cleaner, comprising:

at least one suction brush;

at least one dust collector; and

means for separating the at least one suction brush from a surface to be cleaned.

10. The vacuum cleaner of claim 9, wherein the means for separating includes at least one rolling pin.

11. The vacuum cleaner of claim 9, further comprising at least one guide groove configured to guide dust attracted by the at least one suction brush to the at least one dust collector.

12. The vacuum cleaner of claim 11, wherein the at least one guide groove is configured to be formed proximate to a bottom of the at least one suction brush.

13. The vacuum cleaner of claim 12, wherein the means for separating is formed proximate to the at least one guide groove.

14. The vacuum cleaner of claim 11, wherein the means for separating is formed proximate to the at least one guide groove.
