Example one

Referring to fig. 1, an embodiment of the present application provides a cleaning robot 100, which belongs to the technical field of cleaning equipment, and the cleaning robot 100 includes a base 10, an edge-scan assembly 30, a middle-scan assembly 20 and universal wheels 40, and is mainly used for household sanitation and cleaning.

Wherein, the number of the side-sweeping assemblies 30 is at least two, the side-sweeping assemblies 30 are rotatably arranged on the base 10, each side-sweeping assembly 30 comprises bristles 31 capable of rotating, and at least part of the bristles 31 extend out of one side of the base 10 close to the wall surface 200. The middle-sweep assembly 20 is disposed between two adjacent side-sweep assemblies 30. The universal wheel 40 is rotatably disposed on the base 10, and the rotation axis of the universal wheel 40 coincides with the rotation axis of the edge-sweeping component 30.

In the present embodiment, specifically, in consideration of the prior art: the universal wheel 40 is disposed between the middle-sweeping assembly 20 and the wall surface 200, and occupies the space between the middle-sweeping assembly 20 and the wall surface 200 on the base 10, so that the middle-sweeping assembly 20 cannot be arranged as close as possible to the wall surface 200, and the problem of low coverage rate of the middle-sweeping assembly 20 when the wall surface 200 is swept is caused. The cleaning robot 100 of the present application has the edge-sweeping component 30 and the universal wheel 40 coaxially disposed, and a part of the bristles 31 of the edge-sweeping component 30 extends out of the side of the base 10 close to the wall surface 200. In other words, the bristles 31 are arranged as close to the wall 200 as possible so that the bristles 31 can extend out of the base 10 to contact the corners and seams of the wall.

On the basis that the side-sweeping component 30 is arranged close to the wall surface 200, the middle-sweeping component 20 is arranged between the side-sweeping components 30, so that the side-sweeping component 30 and the middle-sweeping component 20 are arranged close to the wall surface 200, the problem that most cleaning robots 100 on the market are low in cleaning coverage rate is solved, and the area which is not cleaned is reduced.

When cleaning the wall surface 200 or the corner, on one hand, the middle sweeping assembly 20 can sweep and suck dust on the passing area, so as to collect the garbage covering the area into the dust collecting box inside the cleaning robot 100; on the other hand, the brush 31 of the side sweeping assembly 30 guides dust and dirt in the gaps and corners of the wall 200 to the position of the middle sweeping assembly 20 by rotating the side sweeping assembly 30, thereby cleaning and sucking the dust and dirt.

Referring to fig. 1 and 6, in some embodiments of the present application, a bottom edge 11 of one side of the base 10 close to the wall surface 200 in the traveling direction is a straight line, two bottom edges 11 of two opposite sides of the base 10 in the traveling direction are straight lines, and an included angle formed between two adjacent bottom edges 11 is θ, which satisfies a relation: theta is more than or equal to 80 degrees and less than or equal to 90 degrees.

The bottom edge 11 of one side close to the wall surface 200 in the traveling direction of the base 10 is set to be a straight line instead of a traditional arc, so that the whole middle-sweeping component 20 can be ensured to be closer to the wall surface 200, and the side-sweeping component 30 can be arranged closer to the connecting part 12 of two adjacent bottom edges 11, thereby further improving the cleaning coverage of the corner and the wall surface 200.

In addition, the angle θ formed between the two adjacent bases 11 satisfies the relation: theta is more than or equal to 80 degrees and less than or equal to 90 degrees, and it can be understood that the angle formed between the two bottom edges 11 is not more than 90 degrees (namely, an acute angle), so that when the cleaning robot 100 cleans the wall angle, the connecting part 12 of the bottom edges 11 can be pressed close to the wall angle, and therefore the side sweeping component 30 is pressed close to the wall angle, the cleaning blind area is reduced, and the cleaning effect is improved.

Exemplarily, the angle θ =90 ° formed between the two adjacent bottom edges 11, that is, the two adjacent bottom edges 11 are perpendicular to each other, when the cleaning robot 100 performs cleaning, the connecting portion 12 of the bottom edge 11 can just fit into the corner, so that the bristles 31 of the edge-cleaning assembly 30 can reach deep enough to clean the corner.
