The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In the present disclosure, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact between the first and second features, or may comprise contact between the first and second features not directly. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

In the description of the present embodiment, the terms "upper", "lower", "right", "left", and the like are used in the orientation or positional relationship shown in the drawings only for convenience of description and simplicity of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.

As shown in fig. 1, the embodiment provides a side brush, which is installed on a sweeping robot and is particularly suitable for cleaning a carpet. The side brush comprises a fixed disc 210, a first brush 220 and a second brush 230, wherein the first brush 220 is arranged in the circumferential direction of the fixed disc 210, the second brush 230 and the first brush 220 are arranged in the circumferential direction of the fixed disc 210 in a staggered manner, the hardness of the first brush 220 is greater than that of the second brush 230, and the first brush 220 and the second brush 230 incline towards the direction close to the cleaning surface from one end connected with the fixed disc 210 to the other end. The first brush 220 with high hardness can pull the hairs of the carpet apart and lift the dust or hairs in the carpet, so that the sweeping robot can suck the lifted dust or hairs into the interior more easily, and the carpet surface can be cleaned more efficiently. Two or more side brushes can be arranged on one set of sweeping robot, and when the two or more side brushes rotate in the same use, garbage can be gathered together towards a specific direction, for example, the garbage can be gathered together towards the direction of a dust suction opening of the sweeping robot, so that the garbage can be cleaned more quickly.

Preferably, as shown in fig. 1, the first brush 220 and the second brush 230 are provided in plurality, and the plurality of first brushes 220 and the plurality of second brushes 230 sweep the floor or the carpet, so that the cleaning efficiency and the cleaning effect can be improved. The plurality of first brushes 220 and the plurality of second brushes 230 are uniformly arranged at intervals, so that a better cleaning effect is ensured; meanwhile, the fixed disk 210 is uniformly stressed when rotating, so that the rotation is more stable.

Further, as shown in fig. 2, the second brush 230 is inclined at an angle greater than that of the first brush 220, that is, the arrangement plane of the first brush 220 is higher than that of the second brush 230, so that when cleaning a flat surface, the softer second brush 230 contacts the ground to clean garbage, while the first brush 220 does not contact or slightly contacts the ground, thereby reducing the abrasion of the first brush 220. When the carpet surface is cleaned, the first brush 220 is in contact with the carpet, because the first brush 220 has higher hardness, the hairs can be pulled out to lift the dust or the hair in the carpet, and meanwhile, the rotating rubber rod can gather the lifted dust or the hair to the vicinity of the dust suction opening, so that the dust or the hair is closer to the dust suction opening and is easier to be sucked into the dust suction opening.

In this embodiment, the first brush 220 is a rubber rod or a scraping bar, the second brush 230 is bristles, the rubber rod or the scraping bar has high hardness and high elasticity, and can pull the bristles of the carpet apart to lift up the dust or hair in the garbage carpet, and the bristles are soft and can clean the floor well. The glue stick or the scraping strip and the fixed disc 210 are integrally formed, so that the processing is convenient and the connection is firm.

Further, as shown in fig. 2, the bristle assembly includes a mounting sleeve 211 and bristles, the mounting sleeve 211 is disposed on the fixed disk 210, one end of the mounting sleeve 211, which is far away from the fixed disk 210, is provided with a slot, the bristles are mounted in the slot, the bristles can be adhered to the mounting slot by glue, and of course, the bristles can also be fixed by other methods without limitation.

Alternatively, the side brush may be composed of the stationary plate 210 and one or more glue sticks, without bristles, and the side brush of this configuration may be dedicated to cleaning carpets and larger particles of trash. The side brush can also be composed of a fixed disc 210 and brush bristles, and is not provided with a glue stick, and the side brush with the structure is suitable for cleaning flat ground.

The embodiment further provides a sweeping robot, which includes a robot main body 100 and the above side brush, wherein the side brush is rotatably disposed at the lower side of the sweeping robot main body 100. A set of sweeping robot can be equipped with the above-mentioned limit brush of multiple structure, select suitable limit brush for use according to the article of specifically sweeping.

Further, as shown in fig. 1, a region of the sweeping robot main body 100 corresponding to the first brush 220 is provided with a protrusion 110, the first brush 220 can elastically abut against the protrusion 110, when the first brush 220 rotates to the protrusion 110, the first brush is pushed by the protrusion 110 to be closely attached to the carpet, and the first brush is suddenly away from the carpet after passing through the protrusion 110, so that flapping vibration is generated, and the garbage in the carpet is vibrated and flown out more strongly, so that the garbage as much as possible is cleaned out of the carpet, and the cleaning effect on the carpet surface is further improved.

Preferably, the height of the protrusion 110 is designed to contact with the first brush 220 without touching the second brush 230, so as to prevent the second brush 230 with a softer material from bending and knotting when touching the protrusion 110, which may affect the cleaning effect.

Further, as shown in fig. 1, the lower side of the sweeping robot main body 100 is recessed inwards to form a receiving area, and the edge brush is rotatably disposed in the receiving area. The inwardly recessed receiving region provides an installation space for the fixing plate 210, and reduces the distance between the dust suction opening and the cleaning surface, so that the garbage is more easily sucked by the dust suction opening.

Preferably, the fixed disc 210 and the sweeping robot main body 100 are in clamping fit, so that the cleaning robot is convenient to disassemble, assemble and replace. According to the difference of cleaning articles, the side brushes with various structures, which are equipped by the sweeping robot, can be quickly replaced.

It can be understood that the above-mentioned edge brush structure can be applied not only to a sweeping robot, but also to other cleaning devices.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, rearrangements and substitutions will now occur to those skilled in the art without departing from the scope of the invention. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
