AI Technical Summary
Existing robotic vacuum cleaners suffer from problems such as complex structure, high cost, and poor cleaning effect when dealing with hair entanglement. In particular, the dual-section brush shaft design makes positioning difficult and hair difficult to suck up.
The roller brush structure features an inclined bristle planting and comb tooth design. It uses spiral grooves and spiral card slots in conjunction with a film to gather the hair by inclined bristle planting and then uses comb teeth to scrape off the hair, causing it to concentrate into the dust collection hole. The scraper and comb teeth further separate the hair to prevent tangling.
It achieves efficient hair collection with a hair cleaning rate of over 90%, solves the problem of hair tangling, simplifies the structure, and reduces costs.

Abstract
Claims
1. A hair winding prevention structure of a sweeping robot, comprising a bottom shell, a rolling brush cavity, a dust box and a dust collecting hole, the rolling brush cavity is arranged at the bottom of the bottom shell, the dust box is arranged on the bottom shell close to the rolling brush cavity, and the dust box and the rolling brush cavity are communicated through the dust collecting hole, characterized in that: A brush cover is snapped into the opening of the brush cavity. A roller is installed inside the brush cavity. A transmission head and a support head are fixedly connected to both ends of the roller. The transmission head and the support head are movably connected to the grooves at both ends of the brush cavity. A dust suction hole is provided on the brush cover at the position corresponding to the roller. The outer wall of the roller is provided with a spiral groove and a spiral slot respectively. A film is inserted into the spiral slot. Hair is attached to the outer wall of the roller near the film. A comb tooth 1 is provided on the upper edge of the inner wall of the roller brush cavity near the dust collection hole for scraping hair. A comb tooth 2 is provided on the side wall of the dust collection hole away from the dust collection hole for scraping hair.
2. The hair winding prevention roller brush structure of the sweeping robot according to claim 1, wherein: The two sets of spiral grooves are symmetrically opened with reference to the center of the roller and connected in sequence. The two connected spiral grooves are V-shaped, and the number of spiral grooves in each set is not less than three.
3. The anti-hair entanglement roller brush structure for a sweeping robot according to claim 2, characterized in that: The two sets of spiral grooves are symmetrically opened with reference to the center of the roller and connected in sequence. The two connected spiral grooves are V-shaped. The number of spiral grooves in each set is the same as the number of spiral grooves in each set, and they are all arranged in a ring with reference to the center of the roller.
4. The hair winding prevention roller brush structure of the sweeping robot according to claim 1, wherein: Several of the aforementioned hair grafts are arranged at equal intervals along the film, with each hair graft inclined toward the center of the roller, and the inclination angle ranging from 30° to 60°.
5. The hair winding prevention roller brush structure of the sweeping robot according to claim 1, wherein: The comb teeth consist of two sets of toothed plates symmetrical about the center of the roller. The toothed plates in each set are arranged at equal distances and their height increases from the edge to the center. Both sets of toothed plates are inclined towards the center of the dust collection hole so that the gap between each adjacent toothed plate corresponds to each hair graft. This is used to scrape the hair on the hair graft and suck it into the dust box through the dust collection hole. Adjacent toothed plates are also connected by baffles. The side of the toothed plate away from the inner wall of the roller brush cavity increases in height from the side away from the dust collection hole to the other side.
6. The hair winding prevention roller brush structure of the sweeping robot according to claim 1, wherein: The comb teeth are composed of several equally spaced tooth plates, and the height of the tooth plates decreases from the middle to both sides.
7. The anti-hair entanglement roller brush structure for a sweeping robot according to claim 1, characterized in that: The inner wall of the suction hole is also provided with a scraper blade opposite to the comb teeth, and the bottom of the scraper blade extends outward from the suction hole.
8. The hair winding prevention roller brush structure of the sweeping robot according to claim 1, wherein: The support head is ring-shaped, and an anti-tangle pad is fixedly connected to the outer wall of the support head.
