The brush hair can be planted on the rolling body of the rolling brush in the existing dust collector floor brush, and the brush hair and the rolling body are easy to be wound with hair in the rotating process of the rolling brush. It is common to implant bristles normal to the surface of the roller body or at an angle in the same direction as the direction of rotation of the roller brush, however both of these approaches still tend to lift the hair up onto the roller body.

Therefore, in view of the above-mentioned technical problem that the rolling brush in the vacuum cleaner is easy to pick up hairs and wind the hairs around the rolling body, as shown in fig. 1 and 2, the present invention particularly designs a rolling brush assembly, which includes a rotating shaft 1, a rolling body 2, and at least one brush strip 3, wherein the rotating shaft 1 penetrates through the rolling body 2 and can drive the rolling body 2 to rotate, the at least one brush strip 3 is disposed on the outer surface of the rolling body 2, each brush strip 3 includes a plurality of brush units 30, one end of each brush unit 30 is connected with the outer surface of the rolling body 2, the other end of each brush unit 30 is inclined in a direction opposite to the rotation direction of the rolling body 2, and the inclined angle α is an acute angle.

The bristle unit 30 may be a bristle tuft or a bristle strip, and the bristle tuft is preferably used in this embodiment. The bristle unit 30 and the roller body 2 can form an integrated structure by directly planting the bristle bundles on the roller body 2, thereby simplifying the manufacturing process of the roller brush and increasing the use reliability of the roller brush. As shown in fig. 2, the brush bar 3 includes a first brush bar 31 and a second brush bar 32, the first brush bar 31 extends from one end of the roller 2 in a first spiral direction on the outer surface of the roller 2, the second brush bar 32 extends from the other end of the roller 2 in a second spiral direction on the outer surface of the roller 2, the first spiral direction and the second spiral direction are opposite, the first brush bar 31 and the second brush bar 32 are overlapped in a middle portion (middle portion is shown as B-B in fig. 2) of the outer surface of the roller 2 and form a V-shape in the middle portion (middle portion is shown as B-B in fig. 2) of the roller, and the brush bars 3 are spaced along the outer surface of the roller 2.

The round brush subassembly still includes sand grip 4, and sand grip 4 is located between two adjacent brush strips 3, and the distribution form of sand grip 4 on the surface of rolling body 2 and the distribution form of brush strip 3 on the surface of rolling body 2 tend to unanimously, and further, sand grip 4 and brush strip 3 are parallel to each other on the length direction of rolling body 2. Meanwhile, the height of the convex strips 4 protruding out of the outer surface of the roller body 2 is less than the height of the brush strips 3 protruding out of the outer surface of the roller body 2. This is because under the supporting action of sand grip 4, can make the hair adhere to and preferentially strut by sand grip 4 before on brush strip 3, do benefit to the hair and break away from the round brush, and then avoid closely twining the round brush and being twined because of the hair and dying, guarantee that the surface of round brush is clean and tidy and normally rotate.

Further, the spiral direction of the convex strips 4 and the brush strips 3 in each row at one end of the roller body 2 is opposite to the spiral direction at the other end of the roller body 2. So set up for every row of sand grip 4 is the V-arrangement with brush 3 is whole and arranges in the outer peripheral face of rolling body 2, thereby makes hair and filiform thing etc. that twine on rolling body 2 stir and gather together to the middle part of rolling body 2, and adsorb by the absorption mouth of dust catcher and collect.

In a possible implementation manner, the raised strips 4 and the brush strips 3 in each row are spirally arranged on the outer circumferential surface of the rolling body 2, so that dust, garbage and the like can move to the adsorption port of the dust collector along with the rotation of the rolling brush, and the cleaning effect of the dust collector is improved.

Referring to fig. 3, a sectional view of a roll brush assembly according to an embodiment of the present invention is shown along line a-a. The roller body 2 rotates around the rotating shaft 1, the center line of the rotating shaft 1 is a line C-C in figure 3, and the brushing unit 30 is formed by directly planting the hair bundles on the roller body 2, so that one end of the brushing unit 30 is planted in the roller body 2 and forms a joint part with the roller body 2, and the brushing unit 30 and the roller body 2 can form an integrated structure, thereby simplifying the manufacturing process of the roller brush and increasing the use reliability of the roller brush. The other end of the bristle unit 30 is exposed to the outer surface of the roller body 2 and inclined in a direction opposite to the rotation direction of the roller body 2. Specifically, as shown in fig. 3, the rotation direction of the rotation shaft 1 is counterclockwise rotation, and the other end of the brush unit 30 is inclined in a clockwise direction in a reverse direction. After the arrangement, soft garbage such as hair is not easy to pick up in the process that the rolling body 2 rotates along with the rotating shaft 1, thereby reducing the probability that the hair is wound on the rolling body.

Specifically, the other ends of the bristle units 30 are exposed to the outer surface of the roller body 2 and inclined in the opposite direction to the rotation direction of the roller body 2, and the inclination angle of the bristle units 30 is acute, i.e., the inclination angle is 0 ° < α < 90 °. As shown in fig. 3, a midpoint of a joint of the bristle unit 30 and the outer surface of the roller 2 is selected, a line passing through the midpoint and being connected to the axis of the roller 2 is a first extension line, a line passing through the midpoint and being parallel to the length direction of the bristle unit 30 is a second extension line, and an included angle between the first extension line and the second extension line is an inclination angle α of the bristles. In the range of 0 degrees < alpha < 90 degrees, the larger the angle alpha of the inclination angle is, the better the anti-hair-tangling effect is, namely, the larger the angle alpha is, the more difficult soft garbage such as hair is to be picked up, thereby reducing the probability that the hair is twined on the rolling body. This is because in the case where the direction of inclination of the brush unit 30 is opposite to the rotation direction of the roller body 2, the direction of the cleaning force generated by the brush unit 30 and the carpet or floor is opposite to the direction of inclination of the brush unit 30, and thus the probability of the hairs or the like being entangled on the roller brush is reduced. Meanwhile, since the inclination direction of the brush unit 30 is opposite to the rotation direction of the roller 2, the direction of the cleaning force generated by the brush unit 30 and the carpet or the floor is the same as the rotation direction of the roller 2, and the soft garbage such as hair on the floor or the carpet does not fly upward due to the force in this direction, so that a good dust-proof effect is also brought to a certain extent, but the dust-proof capability of the roller brush is affected by the change of the inclination angle. I.e. the larger the angle of inclination a, the less the cleaning force of the brush unit 30 against the carpet or floor will be, and the different the dust-proof effect will be. In the range of the inclination angle of 0 degrees < alpha < 90 degrees, the preferred angle range of the inclination angle of alpha < 30 degrees is the range, and in the range, the rolling brush has good dustproof effect and cannot be influenced by the change of the inclination angle. When the inclination angle is changed within the range of more than 30 degrees and less than 40 degrees, the dustproof effect is reduced along with the increase of the inclination angle alpha, the problem of the reduction of the dustproof capacity caused by the increase of the inclination angle can be counteracted by increasing the thread diameter of the bristle unit 30 to enhance the hardness of the implanted bristles, namely, in the angle range, even if the inclination angle is increased, the influence caused by the angle change can be compensated by increasing the thread diameter of the bristle unit 30, and the dustproof effect of the rolling brush can be further improved.

The embodiment of the utility model also provides a dust collector with the rolling brush assembly, and the specific structure of the rolling brush assembly is shown in the embodiment and is not described herein again. In a possible embodiment, when the rotating shaft 1 of the drum brush assembly of the present embodiment rotates in a counterclockwise direction along with the advancing direction of the cleaner, the other end of the bristle unit 30 exposed to the outer surface of the drum 2 is inclined in a direction opposite to the rotating direction of the drum 2, and the inclination angle of the bristle unit 30 is an acute angle, so that the drum brush can reduce the probability of hair being entangled on the drum, thereby improving the dust removing effect of the cleaner to some extent.

Through the rolling brush assembly and the dust collector with the rolling brush assembly, the probability that hair is wound on the rolling body can be reduced by the rolling brush, and the dust removal effect of the dust collector can be improved to a certain extent.

All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the utility model. It should be noted that various changes and modifications can be made by those skilled in the art without departing from the spirit of the utility model, and these changes and modifications are all within the scope of the utility model.
