ABSTRACT:
A brush structure includes a rotation bar, a plurality of brush strips, a plurality of fixing blocks, and a driving block mounted on the rotation bar to rotate the rotation bar. Thus, the helical groove is extended through the whole length of each of the two arc-shaped plates of the rotation bar, so that each of the two brush strips is extended through the whole length of each of the two arc-shaped plates of the rotation bar without interruption, thereby enhancing the cleaning effect of each of the two brush strips.
