Title:
ELECTRIC CLEANING BRUSH
Document Type and Number:
WIPO Patent Application WO/2021/175329
Kind Code:
A1
Abstract:
An electric cleaning brush (10, 20, 30), comprising a handle (11, 21, 31); a connecting member (12, 22, 32); a rolling brush (13, 23, 33) that has a brush layer that touches a surface to be cleaned; and a support plate (14, 24, 34). The rolling brush (13, 23, 33) rotates relative to the support plate (14, 24, 34) toward the direction of an operator by using a rotating shaft as a center. The handle (11, 21, 31) has at least two operating positions, an included angle between the axis of the handle (11, 21, 31) and the surface when in a first operating position is greater than an included angle between the axis of the handle (11, 21, 31) and the surface when in a second operating position, and the minimum distance between the support plate (14, 24, 34) and the surface when in the first operating position is less than the minimum distance between the support plate (14, 24, 34) and the surface when in the second operating position. The electric cleaning brush (10, 20, 30) may automatically adjust the maximum effective working length of bristles. Even if the handle (11, 21, 31) is raised too high or the amount of pressure applied to the handle (11, 21, 31) is too great, the electric cleaning brush (10, 20, 30) will not produce large or fast friction, kick force or reverse travel stroke, which improves the ease of use thereof and increases the cleaning efficiency.
