[0032] In a preferred embodiment, the bottom shell of the chassis 1 is formed with a mounting groove 11, and a first through hole 12 is formed on one side of the mounting groove 11. A comb tooth structure 13, integrally formed on the bottom shell with its teeth inclined and guided to one side of the first through hole 12, is also present. Specifically, the mounting groove 11 is formed in a semi-cylindrical shape on the bottom shell, and engaging grooves for engaging the roller brush 2 are formed on both the left and right ends of the mounting groove 11 along its length. The first through hole 12 is formed on the side of the mounting groove 11 near the dust collection box. The teeth of the comb tooth structure 13 are inclined towards the dust collection box. More specifically, the comb structure 13 includes a plurality of comb teeth disposed on the bottom shell and inclined to one side of the first through hole 12, with a spacing between adjacent comb teeth, and the angle between each comb tooth and the side of the first through hole 12 being an acute angle, further, the acute angle being 30°, and the height of each comb tooth increasing from the end near the roller brush 2 towards the end near the side of the first through hole 12. In some other preferred embodiments, the comb structure 13 is detachably disposed on the mounting groove 11 of the bottom shell.

[0033] In a preferred embodiment, the roller brush 2 is mounted on the mounting groove 11, specifically, the left and right ends of the roller brush 2 are engaged with the engaging groove. Several sets of brush modules 21 are regularly formed on the periphery of the roller brush 2. The brushes on each brush module 21 are obliquely protruding from the roller, providing an axial force towards the center of the roller to the debris. Specifically, each brush module is arranged in a V-shape along the length of the roller side, and each brush module 21 includes two sets of brush units located on either side of the central axis along the length of the roller brush 2, obliquely designed towards the central axis.

Furthermore, the bristles on both sides of the central axis are installed at a 45° angle, so that they work together to provide an axial force towards the central axis, causing the hair to gather in the central direction during operation. Even further, when the roller brush 2 is rotated, the comb tooth structure 13 is located on the open side of the V-shaped structure of the brush module 21. When the hair gathers, the comb teeth will hook the gathered hair off the brush bristles, and at the same time, the hair is sucked into the dust collection box.

[0034] In a preferred embodiment, the base plate bracket 3 is formed with a first through groove 31 for mounting the roller brush 2, and is fixed to the chassis 1 by a buckle 32. This structure makes the product easy to assemble and disassemble.

[0035] As can be seen from the above description, the anti-hair tangling mechanism for a sweeper of this utility model has bristles designed at a certain angle, which provides axial force to hair and other debris. Together with the comb teeth on the chassis 1, the hair is hung up and sucked into the dust collection box by suction. This prevents the product from being tangled by hair during use, thereby avoiding resistance when sweeping and extending the product's service life. In addition, it also overcomes the need to manually clean the hair from the roller brush, improving the user experience.
