Title:
ROLLER BRUSH CAPABLE OF PREVENTING TRASH FROM SCATTERING AND APPLICABLE TO UNDERWATER CLEANING ROBOT
Document Type and Number:
WIPO Patent Application WO/2020/107822
Kind Code:
A1
Abstract:
A roller brush capable of preventing trash from scattering and applicable to an underwater cleaning robot, comprising a brush component (3) rotatably disposed in a forward direction of a dirt suction port (2). The dirt suction port (2) is disposed at a bottom portion of a main unit (1). The brush component (3) comprises a tapered portion (31) located in the forward direction of the dirt suction port (2). The tapered portion (31) forms an arch-shaped dirt collection channel (32) with respect to the ground. During operation of a device, the brush component (3) rotates and generates an eddy current, such that trash in front of the device enters the dirt suction port (2) via a gap between the brush component (3) and the ground. The tapered portion (31) causes trash near the brush component (3) to be collected at the dirt collection channel (32). The structure has a reasonable layout and stable operation, and can prevent trash from scattering towards two ends of the roller brush.
