A roller brush body of the roller brush component is rotatably mounted in a sleeve. The roller brush body is provided with bristles arranged in an elongated shape to form a bristle portion. The sleeve of the roller brush component has an avoidance opening of an elongated shape, and the bristle portion and the avoidance opening are arranged to directly face towards each other in a radial direction of the roller brush body. A first driving member of the driving mechanism is configured to drive the roller brush body to rotate, and a second driving member is configured to drive the sleeve to rotate. The first driving member and the second driving member are eccentrically arranged to allow the bristle portion to be selectively extended or retracted through the avoidance opening.

    摘要： A surface cleaning head includes an openable agitator chamber to provide access to an agitator, such as a brush roll, for purposes of removing debris and/or removing the agitator. The openable agitator chamber is covered by an external cover that is movable between an open position and a closed position. A sealing member may be located between the external cover and a surface cleaning head housing and around a perimeter of the agitator chamber. A surface cleaning head includes a removable rotatable agitator, such as a brush roll, which is driven by a drive mechanism that axially engages the driven end. At least one end of the removable agitator may be secured in the agitator chamber by the external cover. The surface cleaning head may also include one or more transparent regions (e.g., on the openable cover) to allow visual inspection of the agitator during use.
