Description

Floor sweeping robot capable of switching brushes Technical Field The invention relates to the technical field of sweeping robots, in particular to a sweeping robot with a switchable brush. Background With the continuous development of intelligent household technology, the sweeping robot is used as an important tool for household cleaning, and is widely applied to various families and office places, and the core functions of the sweeping robot are to realize efficient cleaning of ground sundries in modes of brush cleaning, dust collection and the like. At present, the edge brush mechanism of the sweeping robot on the market mostly adopts a single type of brush, namely a thin brush or a thick brush, and is difficult to adapt to different types of ground sundries and ground environments. Specifically, although the fine brush can effectively clean fine impurities such as dust and hair, the cleaning efficiency is lower when the brush faces larger particle impurities (such as grains, scraps and small stones), the problems of hair winding and impurity clamping are easy to occur, and the coarse brush is suitable for cleaning the larger particle impurities, but the brush has harder bristles and larger intervals, so that the fine dust and hair in ground gaps are difficult to clean, and dead corners are easy to clean. Meanwhile, the brushes of the existing sweeping robots are of fixed mounting structures, the types of the brushes cannot be switched according to cleaning requirements, if a user needs to clean fine sundries and larger particle sundries, the sweeping robots with different brushes are required to be additionally provided, or the brushes are detached and replaced, so that the operation is complex, and the use cost and maintenance difficulty of the user are increased.
