The width of the anti-wind structure 14231 along the circumferential direction of the base 1420 is the same as the width of the brush along the circumferential direction of the base 1420, and the centers of the two may or may not coincide with each other in the vertical direction. When the centers of the two coincide in the vertical direction (as shown in fig. 4), the projection of the anti-winding structure 14231 in the vertical direction completely falls on the brush, and the projection of the anti-winding structure 14231 in the vertical direction completely coincides with the brush.

Fig. 5 is a schematic structural diagram of another side brush according to an embodiment of the present invention, as shown in fig. 5, when the center of the anti-winding structure 14234 and the center of the brush are not overlapped in the vertical direction, the projection of the anti-winding structure 14234 in the vertical direction partially overlaps with the bristle base 143, specifically, a part of the projection of the anti-winding structure 14234 in the vertical direction falls on the brush, and the other part does not exist, at this time. Dirt such as hair can not only pile up between brush (for example value hair base 143) and anti-wind structure 14234, also can pile up in anti-wind structure 14234 and the position that the projection of the vertical direction of value hair base 143 is misaligned, can reach and pile up more dirty effects, and simultaneously, this setting makes dirt such as hair can be by more convenient observation and clearance of user.

In this embodiment, as the cleaning robot works for a period of time, dirt such as hair on the floor is accumulated between the brush (e.g., the bristle base 143) and the anti-winding structure 14231/14234, so as to effectively prevent the hair from winding around the rotating shaft 112, and when the cleaning action is stopped, the user can remove the hair between the brush and the anti-winding structure by detaching the lower side brush.

Example two

Fig. 6 is a schematic structural view of a two-sided brush according to an embodiment of the present invention. As shown in fig. 6, the bristle base 143 is protruded on the base 1420, that is, the bristle bundle 1421 is fixed on the base 1420 through the bristle base 143, which is different from the first embodiment in that the width of the anti-winding structure 14232 along the circumferential direction of the base 1420 is greater than the width of the bristle base 143 along the circumferential direction of the base 1420, and the width of the anti-winding structure along the circumferential direction of the base 1420 is less than 4 times, preferably less than 2 times, of the width of the brush along the circumferential direction of the base.

Similar to the embodiment, the center of the anti-wind structure 14232 and the center of the brush (bristle base 143) may or may not coincide in the vertical direction. When the centers of the two coincide in the vertical direction (as shown in fig. 6), the projection of the middle portion of the anti-wind structure 14232 in the vertical direction falls on the brush, and the projections of the anti-wind structure 14232 in the width direction thereof beyond both side portions of the brush do not fall on the brush. When the centers of the two are not coincident in the vertical direction, the projection part of the anti-winding structure in the vertical direction falls on the brush, and it should be noted that, at this time, the projection of the anti-winding structure in the vertical direction that does not fall on the brush may be 1 (that is, the center distance of the two is farther, one side of the projection of the anti-winding structure falls on the brush, and the other side is not), or may be 2 (that is, the center distance of the two is closer, one side of the projection of the anti-winding structure close to the center falls on the brush, and both sides of the center are not).

In this embodiment, as the cleaning robot works for a period of time, dirt such as hair on the floor is accumulated between the brush (e.g., the bristle base 143) and the anti-winding structure 14232, thereby effectively preventing the hair from winding around the rotating shaft 112, and when the cleaning action is stopped, the user can remove the hair between the brush and the anti-winding structure by detaching the brush. The width of the anti-winding structure 14232 along the circumferential direction of the base 1420 is larger than the arrangement of the hair base 143 along the circumferential direction of the base 1420, so that after the dirt such as hair is clamped on the anti-winding structure 14232, the dirt such as hair can be observed and cleaned more conveniently by a user. In particular, as long as the side edge of one end of the anti-winding structure 14232 exceeds the bristle base, the dirty bits such as hairs can be caught on the anti-winding structure 14232 exceeding the bristle base 143.

EXAMPLE III

Fig. 7 is a schematic structural view of a three-sided brush according to an embodiment of the present invention. As shown in fig. 7, the bristle base 143 is protruded from the base 1420, that is, the bristle bundle 1421 is fixed on the base 1420 through the bristle base 143, but this embodiment is different from the first embodiment in that the width of the anti-wind structure 14233 along the circumferential direction of the base 1420 is smaller than the width of the bristle base 143 along the circumferential direction of the base 1420.

Similar to the embodiment, the center of the anti-wind structure 14233 may or may not coincide with the center of the bristle base 143 in the vertical direction. When the centers of the two coincide in the vertical direction (as shown in fig. 7), the projection of the anti-wind structure 14233 in the vertical direction completely falls on the brush. When the centers of the anti-winding structure 14233 and the bristle base 143 are not vertically coincident, there are two cases, one of which is that the centers of the two are closer, and the projection of the anti-winding structure in the vertical direction still falls completely on the brush; the other is that the center distance between the two is far, and the projection of the anti-winding structure in the vertical direction only partially falls on the brush, so that the dirt such as hair and the like can be observed and cleaned more conveniently by a user.

In this embodiment, as the cleaning robot works for a period of time, dirt such as hair on the floor is accumulated between the brush (e.g., the bristle base 143) and the anti-winding structure 14233, thereby effectively preventing the hair from winding around the rotating shaft 112. The width of the anti-wind structure 14233 in the circumferential direction of the base 1420 is smaller than the arrangement of the bristle base 143 in the circumferential direction of the base 1420, so that the volume of the anti-wind structure 14233 is reduced, thereby enabling more contamination of hair or the like to be accommodated. In particular, even if one end side of the anti-wind structure 14233 does not exceed the bristle base, it is possible to allow dirt such as hair to be caught on the anti-wind structure 14233 that exceeds the bristle base 143.

Example four

Fig. 8 is a schematic structural view of a four-side brush according to an embodiment of the present invention. As shown in fig. 8, in this embodiment, compared with the first embodiment, the bristle base (not shown) is disposed inside the side brush base 1420 or embedded in the side brush base 1420, and the bristle bundle 1421 is fixed on the base 1420 through the bristle base; alternatively, tufts 1421 are mounted directly on base 1420. In this embodiment, the width of the anti-wind structure 14231 in the circumferential direction of the base 1420 is the same as the width of the tufts 1421 in the circumferential direction of the base 1420.

In other embodiments, the bristle base can be embedded in the side brush base, and the projection of the anti-winding structure in the vertical direction can be overlapped with the complete coverage of the bristle bundle or partially overlapped with the bristle bundle.

In this embodiment, because antiwind sets up between base and limit brush holding chamber, and antiwind projection and the at least partial coincidence of tuft of structure in vertical direction, antiwind and tuft can carry out the screens to the filth simultaneously for the filth can be injectd well between tuft and antiwind, prevents its work that further influences the pivot, when reducing the drive assembly spoilage, still does benefit to and concentrates the clearance to the filth.
