The sliver is designed in the form of a sliver, and the structure of the sliver can effectively cover the guide end cover 2. In this way, the sliver can form a barrier to prevent hair and foreign matter from directly contacting the guide end cover 2, thereby reducing the potential risk of blockage and wear. The orthogonal projection of the sliver on the guide end cover 2 covers the guide end cover 2, so that even if foreign matter approaches during the operation of the device, it will be blocked by the sliver first, thereby protecting the end of the guide end cover 2 and the body 1 from being affected. The design of the sliver not only reduces the distance between the stop piece 500 and the outer peripheral wall of the guide end cover 2, thereby preventing hair or foreign matter from directly contacting the guide end cover 2, but also allows the bristles of the brush that extend out of the avoiding slot 22 to push the bristles of the sliver, i.e., the sliver is not designed to excessively interfere with the end of the brush, thereby further improving the ability to block foreign matter or hair. The sliver is arranged to extend towards the center of the dust suction port 220, thereby reducing the friction between the sliver and the outer peripheral wall of the guide end cover 2, reducing the rotational resistance of the roller brush 100 and the corresponding energy consumption, and avoiding the melting of the guide end cover 2 due to excessive temperature. The bristles of the sliver contact the guide end cover 2. During the rotation of the roller brush 100, the bristles of the sliver contact the bristles of the brush on the roller brush 100, which basically does not block or affect the rotation of the roller brush 100. In addition, the sliver can be shaped to fit the guide end cover 2 and the brush on the roller brush 100, thereby minimizing the intrusion of hair into the end of the roller brush 100. The design of the sliver also allows hair and small particles during cleaning to be effectively captured when the brush is working, thereby preventing them from accumulating near the guide end cover 2, improving the overall cleaning performance and maintenance convenience. By effectively blocking the contact of foreign matter, the sliver not only protects the structural integrity of the guide end cover 2 and the body 1, but also prolongs the service life of the device and improves the user experience.

[0050] In another embodiment, referring to Figure 4 and Figure 5 , the outer peripheral wall of the guide end cover 2 is spaced apart to form a plurality of inclined edges 24, and a groove 25 is formed between any two adjacent inclined edges 24. The orthogonal projection of the sliver on the guide end cover 2 covers the guide end cover 2. In this way, the contact area between the guide end cover 2 and the sliver is also reduced, thereby reducing the friction. In addition, the sliver can extend into the groove 25, thereby better preventing hair from invading and winding around the guide end cover 2.

[0051] Further, for the convenience of replacing the stop piece 500, referring to Figure 3 and Figure 4 Figure 4 Figure 5In an embodiment of the present application, the rolling brush assembly comprises a mounting bracket 600, the mounting bracket 600 is connected with the guide end cover 2, and the stopper 500 is detachably connected with the mounting bracket 600. The stopper 500 and the mounting bracket 600 are detachably connected, so that the user can replace the stopper 500 simply, which saves time and effort and reduces the maintenance difficulty. This design enables the user to quickly replace the stopper 500 during use, avoids the influence of the wear or dirt of the stopper 500 on the cleaning effect, and improves the overall working efficiency of the equipment. The detachable connection mode not only facilitates replacement, but also simplifies the cleaning process. The user can regularly check and clean the stopper 500 to ensure that it is always in good condition.

[0052] The utility model also proposes a kind of sweeping robot, and sweeping robot includes shearing mechanism 700, adsorption mechanism and the rolling brush assembly described in any one embodiment above, the shearing mechanism 700 is movably arranged in the body 1;The adsorption mechanism is arranged in the body 1.It can effectively decompose longer hair by shearing mechanism 700, to prevent its entanglement on rolling brush assembly, to improve cleaning efficiency;Adsorption mechanism is also arranged in the body 1, aims at by suction force, dust and small particle generated in cleaning process are inhaled into dust collection box, this design ensures that ground cleaning is more thorough, and rolling brush assembly is cooperated, reaches best cleaning effect;The sweeping robot utilizes the function of shearing, adsorption and rolling brush 100 by comprehensive utilization, can adapt to multiple ground materials, realizes intelligent, efficient cleaning, user does not need frequent maintenance in use process, improves overall user experience.

[0053] The above-mentioned is only the exemplary embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the present application.
