First Claim
Patent Images
1. A suction brush assembly of a vacuum cleaner comprising:
- a housing having a suction duct to provide a suction passage for dust;
a pair of rotation members rotatably disposed close to both sides of a suction port, respectively, of the suction duct and having at least one protrusion formed on an outer circumference thereof;
at least one wheel disposed at the housing;
a power transmission unit to rotate the rotation members by exerting a rotation force of the wheel to the rotation members when the wheel is rotating; and
a settlement member to relatively fix the pair of rotation members.

Abstract
A suction brush assembly of a vacuum cleaner has a housing having a suction duct to provide a suction passage for dust, a rotation roller having a plurality of ribs formed at an outer circumference, a wheel disposed at the housing, and a power transmission unit to rotate the rotation member by exerting a rotation force of the wheel to the rotation member when the wheel is rotated. The wheel and the rotation member are rotated in directions opposite to each other by the power transmission unit. When a user wants to clean fabrics such as bedclothes or a carpet, the effect of hitting of the ribs can be firmly secured due to the rotation of the rotation rollers. Therefore, the effect of removing dust remarkably increases.
