Fig. 1 shows a partial cross-sectional view of a floor brush. Referring to fig. 1, the floor brush includes a floor brush housing 10, a rolling brush 20, a wiper strip and an air duct connecting portion 50. The rear end of the floor brush shell 10 is connected with an air pipe connecting part 50, the air pipe connecting part 50 is used for being connected and fixed with an air pipe of a dust collector, the floor brush shell 10 is provided with an accommodating cavity positioned at the front part of the floor brush shell 10 and a suction channel opening 30 positioned at the middle part of the floor brush shell 10, and the rear end of the accommodating cavity is communicated with the suction channel opening 30; the rolling brush 20 can be installed in the accommodating cavity through a rotating shaft, for example, and the rolling brush 20 can be rotatably installed in the accommodating cavity by providing a rotating power through a power device such as a motor; the wiper strip is installed and fixed between the suction passage opening 30 and the drum brush 20, and is used to peel off the hairs from the drum brush 20 and suck the hairs through the suction passage opening 30, so that the hairs cannot be wound around the drum brush 20.

Referring to FIG. 1, the floor brush further includes a front driving wheel (not shown) and a rear driving wheel 60 for supporting the floor brush on a surface to be cleaned (e.g., a floor or a carpeted surface) during contact therebetween.

Fig. 2 shows a front view of a roll brush 20 according to the present invention, the roll brush 20 comprising a roll brush body 21, at least one spiral rib 22 and at least one row of bristles 23.

Referring to fig. 2, in the present embodiment, the rolling brush 20 includes a plurality of spiral ribs 22 (e.g., three spiral ribs 22 shown in fig. 2), and the plurality of spiral ribs 22 are disposed at equal intervals or at random intervals along the circumferential direction of the rolling brush body 21. As a common knowledge, in the process of winding the hair around the roller brush 20, if the outer diameter of the roller brush 20 is larger, the hair is difficult to wind (the hair needs to wind around the roller brush 20 at least one time and may not be sucked away), therefore, by providing the spiral rib 22 structure on the surface of the roller brush body 21, the present application can not only generate a spiral force when the roller brush 20 rotates at a high speed, but also move the hair to the middle suction port area of the suction channel port 30, so as to facilitate the hair to be sucked away; moreover, the spiral rib 22 structure is equivalent to change the direction to increase the outer diameter of the brush body of the rolling brush 20, so that the hair can be effectively prevented from being wound on the rolling brush 20, and the implanted hair 23 is not influenced.

Referring to fig. 2, in the present embodiment, each spiral rib 22 is circumferentially disposed on the outer surface of the rolling brush body 21 along the axial direction of the rolling brush body 21, and each spiral rib 22 includes a first spiral rib segment and a second spiral rib segment which are disposed in sequence and have opposite spiral directions; the first spiral rib segment and the second spiral rib segment extend from the two ends of the roll brush body 21 to the middle and are connected at the middle position of the roll brush body 21, and the first spiral rib segment and the second spiral rib segment of each spiral rib 22 are symmetrically arranged about the center of the roll brush body 21. As an example, the geometric shape of the axial cross section of the spiral rib 22 may be, for example, a triangle, a trapezoid, a rectangle, a circular arc, or the like. As an example, the cross-sectional shape of the spiral rib 22 is a trapezoid, and is tapered outward from the surface of the roll brush body 21. It should be noted that the number of the spiral ribs 22 of the rolling brush 20 and the number of the rows of the bristles 23 may be appropriately selected according to the diameter of the rolling brush body 21 and the actual requirement, and is not limited to the number shown in fig. 2.

Referring to fig. 2, in the present embodiment, the heights of each spiral rib 22 may be the same or different. As an example, the height of the spiral ribs 22 gradually decreases from the two ends of the rolling brush body 21 to the middle, and the height difference (the difference between the height of the spiral ribs 22 at the ends and the height of the spiral ribs 22 at the middle) is 0-5mm, such as 1mm, 2mm, 3mm, 4mm or 5 mm.

Referring to fig. 2, in the present embodiment, the rolling brush 20 further includes a plurality of rows of bristles 23 (e.g., three rows of bristles 23 shown in fig. 2) adjacent to the spiral rib 22, the plurality of rows of bristles 23 are disposed at equal intervals or at random intervals along the circumferential direction of the rolling brush body 21, and each row of bristles 23 includes a plurality of bristle-planting units. Each row of bristles 23 is arranged on the outer surface of the rolling brush body 21 in a surrounding manner along the axial direction of the rolling brush body 21 and located on one side of the spiral rib 22, each row of bristles 23 is parallel to (certainly not parallel to) the corresponding spiral rib 22, that is, the distance between each row of bristles 23 and the corresponding spiral rib 22 is the same everywhere, in other words, each row of bristles 23 is arranged along two mutually connected spiral line segments with opposite spiral directions, and the two spiral line segments are respectively parallel to the first spiral rib segment and the second spiral rib segment of the corresponding spiral rib 22. As an example, each row of bristles 23 may be located, for example, behind the spiral rib 22 corresponding to the row of bristles 23 in the rotation direction of the roller brush 20.

Referring to fig. 2, in the present embodiment, the height of the planted hair 23 is higher than that of the spiral rib 22, so that when the hair is rolled up by the planted hair 23 of the roller brush 20, the hair is not wound around the root of the planted hair 23 under the support of the spiral rib 22, and thus the hair can be peeled off from the planted hair 23 of the roller brush body 21 by the scraping bar to be described later and sucked away. In addition, the height of the bristles 23 is required to ensure that the bristles 23 can be exposed from the opening 11 (shown in fig. 3 and 7) at the bottom of the floor brush, and the height of the spiral ribs 22 is required to ensure that the spiral ribs 22 are not exposed from the opening 11 at the bottom of the floor brush, so that the bristles 23 can extend into the carpet without damaging the carpet by the spiral ribs 22 when the floor brush is in operation.

The end of the elastic scraping bar 40 close to the rolling brush 20 is designed to be non-toothed (planar structure) as shown in fig. 5 or toothed like fig. 9 to be described later, and the end of the toothed elastic scraping bar 40 close to the rolling brush 20 is provided with a groove corresponding to the bristles 23 of the rolling brush 20, which not only can prevent the scraping bar and the bristles 23 from frictional wear and influence the dust removing efficiency, but also can reduce the load of the driving motor of the rolling brush 20.

To facilitate the peeling of the hair from the roller brush 20, the free end of the elastic wiper strip 40 adjacent to the elastic wiper portion 42 of the roller brush 20 has a pointed structure.

Referring to fig. 3 to 6, in the present embodiment, the elastic scraping portion 42 of the elastic scraping bar 40, which is close to the roller brush 20, has an arc-shaped structure bent toward the bottom of the floor brush housing 10, and in combination with the design of the tip end close to one end of the roller brush 20, hairs can be better peeled off from the roller brush 20, and the peeled hairs can move along the inner arc surface of the elastic scraping bar 40 in a direction away from the roller brush 20, so that the hairs can be better peeled off from the roller brush 20. The design of the elastic scraping strip 40 and the rolling brush 20 can greatly reduce the probability that hair is wound on the rolling brush, and greatly reduce the frequency of cleaning the rolling brush by a user. The elastic scraping strip 40 and the bristles 23 of the present embodiment are in interference scraping, and compared with the existing interference scraping of rigid scraping strips and bristles, the elastic scraping strip 40 not only has little abrasion to the bristles, but also reduces the load of the roller brush motor.
