Referring to fig. 1, a rolling brush 10 includes a roller 12 and at least one brush unit 14, the brush unit 14 is in a bar shape, the brush unit 14 is disposed on the circumferential surface of the roller 12, and the brush unit 14 is disposed along the axial direction of the roller 12; the bristle unit 14 comprises at least two bristle rows 142, each bristle row 142 is distributed along the axial direction of the roller 12, and in each bristle unit 14, the bristle rows 142 are arranged side by side.

In the roller brush 10 of the present embodiment, the roller 12 is used for fixing the brush units 14, and each brush unit 14 includes at least two brush rows 142. When the rolling brush 10 cleans the floor, the bristle units 14 on the roller 12 can not only sweep the garbage into the dust box or the garbage storage box, but also can clamp the garbage in the bristle rows 142 of each bristle unit 14, but when the bristle rows 142 touch the dust box or the garbage storage box, the garbage which can be clamped can be scraped into the dust box or the garbage storage box. Therefore, the rolling brush 10 of the present embodiment has a better cleaning effect, and more conveniently cleans the garbage into the dust box or the garbage storage box.

In one embodiment, the bristle row 142 includes bristles 1422, and in each bristle unit 14, the adjacent bristles 1422 are separated from each other at the end close to the drum 12, so that the bristles 1422 have gaps therebetween, and can hold garbage. The ends of the adjacent bristles 1422 close to the roller 12 are separated from each other, and the ends of the adjacent bristles 1422 far from the roller 12 can be close to each other or far from each other, wherein the ends of the adjacent bristles 1422 far from the roller 12 are close to each other includes two cases, and in one case, in the same bristle row 142, the ends of the adjacent bristles 1422 far from the roller 12 are close to each other. Alternatively, in two rows 142 of bristles, the ends of adjacent bristles 1422 remote from the roller 12 are adjacent to each other, i.e., the adjacent bristles 1422 are from two different rows 142 of bristles, respectively. In a preferred embodiment, the two bristles 1422 may be from the same bristle row 142 or from different bristle rows 142 in units of two bristles 1422, and the ends of the two bristles 1422 remote from the roller 12 are close to each other. Of course, it will be appreciated that in some embodiments, three, four, etc. bristles 1422 may be provided in a unit, with the ends of the three or four bristles 1422 remote from the roller 12 being adjacent to each other.

In a preferred embodiment, when the adjacent bristles 1422 are separated from each other at the end close to the drum 12, the ends of the adjacent bristles 1422 far from the drum 12 should be close to each other, so that the ends of the adjacent bristles 1422 far from the drum 12 hold the garbage. Because the adjacent bristles 1422 are close to each other at the end far from the roller 12, when the rolling brush 10 cleans the ground, the bristles 1422 clamp the garbage, and the bristles 1422 close to each other at the end far from the roller 12 can fix the garbage, so as to prevent the garbage from falling off, and therefore, the cleaning effect of the rolling brush 10 can be further improved.

In one embodiment, in each bristle unit 14, the bristles 1422 in each bristle row 142 are equal in number and correspond to each other, and the ends of the bristles 1422 away from the roller 12 that are corresponding to each other are close to each other or are staggered with each other. When every brush hair 1422 can both be with the brush hair 1422 centre gripping rubbish that corresponds, can not form the brush hair 1422 of "drop one", can effectively improve the centre gripping effect, can be with the centre gripping and fix more rubbish. In particular, in different bristle rows 142, the bristles 1422 correspond to each other one by one, so that the utilization rate of the bristles 1422 is higher when clamping and fixing garbage, and therefore, the cleaning effect of the rolling brush 10 is better.

In an embodiment, after the ends of the two corresponding bristles 1422 far away from the roller 12 are close to each other, the ends of the two corresponding bristles 1422 far away from the roller 12 may contact each other or be staggered or have a certain gap. The bristles 1422 may be made of a plastic material that has a certain rigidity but can be bent. When the rolling brush 10 cleans the floor, the bristles 1422 that are in contact with each other, staggered with each other, or close to each other can be bent, so that the garbage can enter between the bristles 1422, and after the garbage enters between the bristles 1422, the bristles 1422 that are in contact with each other, staggered with each other, or close to each other can fix the garbage, so that the garbage can not fall off.

Referring to fig. 1 and 2, in an embodiment, an included angle between two corresponding bristles 1422 is 1 ° to 30 °, and preferably, the included angle is 10 °. In a specific embodiment, the distance between the two corresponding bristles 1422 far away from the roller 12 is 1mm, the distance between the two corresponding bristles 1422 near the roller 12 is 3mm, and the bristles 1422 can clamp and fix garbage with a certain mass, because the strength of the bristles 1422 is limited, if the mass of garbage particles is large, the bristles 1422 are difficult to fix, and therefore, when the included angle between the two corresponding bristles 1422 is 1 ° to 30 °, the clamping and fixing capability of the bristles 1422 can be effectively and reasonably utilized.

In an embodiment, each of the bristle units 14 includes two bristle rows 142, and two bristle rows 142 in each bristle unit 14 can be paired with each other, and preferably, the bristles 1422 in the two bristle rows 142 can correspond to each other one by one, so that each two bristles 1422 can have the capability of holding and fixing garbage, and the utilization rate of the bristles 1422 is higher.

In one embodiment, the distance between the bristle units 14 is 3mm to 20mm, and preferably, the distance between the bristle units 14 is 6mm, which is more advantageous for sweeping garbage into a dust box or a garbage collection box, and the bristle rows 142 in each bristle unit 14 can be reasonably utilized, can clamp and fix some garbage, and can be brought into the dust box and the garbage collection box.

In an embodiment, the middle of each bristle unit 14 extends along one side of the circumferential direction of the drum 12, each bristle unit 14 forms a V shape, each bristle unit 14 includes at least two bristle rows 142, so each bristle row 142 also forms a V shape, and since the bristle units 14 and the bristle rows 142 are both V-shaped, when the rolling brush 10 cleans the ground, the bristle units 14 and the bristle rows 142 can gather the garbage and sweep the garbage into a dust box and a garbage storage box, so the cleaning effect of the rolling brush 10 is better.

In one embodiment, the bristle elements 14 may also be helical, with the bristle elements 14 being helically distributed along the circumference of the drum 12.
