Description

TECHNICAL FIELD

[0001] The utility model relates to the field of sweeping robot, especially an edge brush and sweeping robot. BACKGROUND

[0002] With the rapid development of modern science and technology, intelligent devices are gradually integrated into people's daily life, greatly improving the convenience and comfort of life. Among them, the intelligent cleaning device, especially the sweeping and mopping robot, has become an important tool for modern family cleaning with its efficient and autonomous cleaning ability. This kind of device not only can perform cleaning task, but also can consider mopping function, through integrated edge brush, roller brush and cloth disc and other components, the overall cleaning from ground dust, debris to stain is realized.

[0003] However, although the sweeping and mopping robot has made significant progress in the technical level, it still faces some problems to be solved in the actual use process. Among them, the problem of easy entanglement of hair and other long fiber objects in the cleaning process of edge brush is particularly prominent. As an important cleaning part of sweeping robot, the main function of edge brush is to close to the corner of wall and the edge of furniture, and to sweep the dust and sundries that are difficult to reach into the dust suction port. However, when long hair or pet hair and other long fibers are encountered, the rotating shaft of edge brush is easy to be entangled.

[0004] This entanglement not only affects the cleaning efficiency of edge brush, leading to incomplete cleaning of some areas, but also may cause damage to the internal structure of robot, shortening the service life of equipment. More importantly, when cleaning these entangled hairs, users often need to manually disassemble the edge brush assembly, which is tedious and time-consuming, greatly reducing the user experience.

[0005] In view of the above problems, some attempts have been made in the prior art to improve the structure of edge brush to reduce hair entanglement. Among them, one solution is to directly extend a blocking piece at the hair implanting place of the bristles of edge brush, aiming to prevent hair from being entangled on the rotating shaft by physical blocking. However, this design exposes some new problems in actual application. Since the blocking piece is directly arranged at the hair implanting place of the bristles, when the hair is pulled in the entangling process, the bristles are often deformed due to additional pressure. This not only affects the cleaning effect of the bristles, but also may exacerbate the entangling phenomenon of the hair due to the change of the bristle form, and even cause damage to the blocking piece itself.
