Brush for cleaning surface, has bunches of bristle-semi rows gathering in center to form V-bristle angle at specific point, where bunches of bristle-semi rows are unhinderedly deflected in its operating function

摘要

The brush has two bunches of bristle-semi rows (11) provided in the shape of a V-bristle zone in a middle part of a brush-base body (1). The bunches of bristle-semi rows are aligned in an opposite direction and possess large inclination angles. The bunches of bristle-semi rows gather in the center to form a V-bristle angle from the sum of two inclination angles at a specific point. An air gap is provided at the point of the bunches of bristle-semi rows, which are arranged angularly opposite to each other. The bunches of bristle-semi rows are unhinderedly deflected in its operating function.
