Abstract:
A roller brush and a cleaning device. The roller brush comprises: a cylinder (1) provided with an accommodating space (11) therein, the accommodating space (11) comprising a first area (111) and a second area (112) located on two sides of any diameter of the cylinder (1); a driving member (2), driving heads (21) of the driving member (2) being located in the accommodating space (11); and a deviation correction structure (3) provided in the roller brush, along the circumferential direction of the cylinder (1) of the roller brush, the deviation correction structure (3) comprising at least three separation members (31) distributed at intervals, a placing space (32) being formed between every two adjacent separation members (31), and the placing spaces (32) being located in the first area (111) and the second area (112) and used for accommodating the driving heads (21). Each separation member (31) has two opposite abutting surfaces (311), an included angle (ɑ) is formed between planes where the two adjacent abutting surfaces (311) are located, and the included angle (ɑ) is greater than 0° and less than 90°. During rotation of the roller brush, the roller brush can correct deviation of a motor assembly (4) so as to avoid damage caused by friction between the motor assembly and the inner wall of the cylinder (1), and noise and power loss can be reduced.
