Embodiment 1:

As shown in Figure 1, this embodiment is a cyclonic expansion anti-hair entanglement roller brush body, including a roller brush body 1, a plurality of cleaning ribs 11 spaced apart from each other are arranged on the surface of the roller brush body 1, and a guide groove 1111 is arranged on the side surface of at least one side of the cleaning rib 11.

In some embodiments, the guide groove 1111 is arranged on the side of the cleaning rib 11 along the length direction of the roller brush body 1. The guide groove 1111 is located on the side facing the area where dirt enters the roller brush body 1. When the roller brush body 1 rotates, the dirt can enter the guide groove 1111 and move away from the surface of the roller brush body under the action of the guide groove 1111.

2(a)-(d), the opening of the guide groove 1111 faces the side of the cleaning rib 11 and faces the direction in which hair and other dirt are sucked in (i.e., the opening of the guide groove 1111 faces the direction indicated by the arrow B in the figure).

Therefore, in the vacuum cleaner equipped with the roller brush body 1 of the utility model, since the opening of the guide groove 1111 faces the side of the cleaning rib 11, that is, when the roller brush rotates, the hair and other dirt will hit the guide groove 1111 head-on. Therefore, under the action of the guide groove 1111, the hair and other dirt will generate a cyclone mode when the roller brush rotates at a high speed. The generated cyclone will expand the hair and other dirt, preventing the hair from naturally entangled on the roller brush body 1, and will not entangle the roller brush body 1. Subsequently, the hair is suspended in the vacuum chamber under the expansion effect of the cyclone and is directly sucked into the dust cup by the vacuum cleaner at the moment, thereby achieving the effect of not entangled hair on the surface of the roller brush body 1.

In some embodiments, the cleaning rib 11 includes a body 111 and a soft scraping layer (not shown), the soft scraping layer can be any material with scraping function such as fluff, bristles or leather strips. The soft scraping layer can be embedded in the body 111 or cover its surface.

The surface of each body 111 that is away from the roller brush body 1 is the first surface 1112. In some embodiments, the first surface 1112 is a cylindrical surface coaxially arranged with the roller brush body 1, thereby facilitating the mold opening and processing of the roller brush body 1. The first surface 1112 of each cleaning rib 11 can be on the same cylindrical surface or on different cylindrical surfaces, that is, the distance between the first surface 1112 of each body 111 and the outer surface of the roller brush body 1 is different. In other possible embodiments, the first surface 1112 can also be a curved surface or an inclined surface.

Referring again to FIG. 2 (a)-(d), the bottom of the guide groove 1111 of the utility model is arc-shaped, plane-shaped or V-shaped. When the bottom is arc-shaped, the guide groove 1111 can be a C-shaped groove or a U-shaped groove. When the bottom is plane-shaped, the guide groove 1111 is a flat-bottomed groove.

In some embodiments, the cleaning ribs 11 are spirally arranged on the surface of the roller brush body 1 .

The cleaning rib 11 may include a first rib body 1113 and a second rib body 1114 connected to each other, and the angle formed by the intersection of the extension lines of the mutually adjacent ends of the first rib body 1113 and the second rib body 1114 is not 180 degrees. Referring to FIG1 , a "V" shape is formed by the first rib body 1113 and the second rib body 1114, and the opening of the V shape faces the direction where hair and other dirt are sucked in, and the guide groove 1111 is arranged on one side of the opening of the first rib body 1113 and the second rib body 1114, that is, hair and other dirt directly hit the guide groove 1111 on the first rib body 1113 and the second rib body 1114 under the action of the suction force, and are gathered to the central area of the roller brush body 1 under the guidance of the shape of the first rib body 1113 and the second rib body 1114, and Furthermore, under the action of the suction force, hair and other dirt are smoothly sucked away without being entangled on the roller brush body 1.

The first tendon 1113 and the second tendon 1114 may be connected or disconnected to each other. When the first tendon 1113 and the second tendon 1114 are connected to each other, the first tendon 1113 and the second tendon 1114 may be connected to each other ..., the first tendon 1113 and the second tendon 1114 may be connected to each other, the first tendon 1113 and the second tendon 1114 may be connected to each other, the first tendon 1113 and the second tendon 1114 may be connected to each other, the first tendon 1113 and the second tendon 1114 may be connected to each other, the first tendon 1113 and the second

The first rib body 1113 and the second rib body 1114 of the cleaning rib 11 may also be integrally connected, that is, the second rib body 1114 continues to rotate along the spiral direction of the first rib body 1113, and the extension line of one end of the first rib body 1113 close to the second rib body 1114 coincides with the extension line of one end of the second rib body 1114 close to the first rib body 1113. That is, the cleaning rib 11 is gradually spirally arranged from one end of the roller brush body 1 to the other end of the roller brush body 1.

In other embodiments, the cleaning ribs 11 may also be arranged along the axial direction of the roller brush body 1. For example, the cleaning ribs may be arranged along a direction parallel to the axis of the roller brush body 1; or the overall arrangement direction may be along the axis of the roller brush body 1, but in a wave shape or tooth shape, so that dirt such as dust can be easily collected at the bottom of the wave or tooth.

Embodiment 2:

This embodiment is a floor brush, which includes the cyclone-expanding anti-hair-entanglement roller brush body of the first embodiment.

The floor brush of this embodiment also includes a reflux member 2 located at the end of the roller brush body 1. As shown in FIG. 3, the reflux member 2 includes at least one group of reflux portions 21. The reflux portion 21 includes an introduction area 211 and a counterflow area 212. The counterflow area 212 is used to redirect the dirt entering the introduction area and move it to the middle area of the roller brush body 1. The introduction area 211 has an introduction surface that gradually moves toward the end of the roller brush body 1. In some embodiments, the introduction surface is set in a direction perpendicular to the outer surface of the roller brush body 1, and can also be tilted at a certain angle, as long as it can achieve the movement of dirt such as hair along the introduction surface toward the two ends of the roller brush body 1. The counterflow area 212 is connected to the introduction area 211, and the counterflow area 212 has a folding surface whose bending direction is opposite to that of the introduction surface.

In some embodiments, each introduction area 211 is connected to a corresponding guide groove 1111. Therefore, even if a small amount of hair remains in the guide groove 1111 and is not expanded and moves to the introduction area 211, the backflow area 212 can block the backflow in time.

In some embodiments, the reflux portions 21 include a plurality of reflux portions 21 that are connected in sequence and arranged in a ring-shaped manner at the end of the roller brush body 1 , and the arrangement direction of each reflux portion 21 is arranged along the circumferential direction of the end of the roller brush body 1 .

Thus, a tortuous serpentine channel is formed between the first retaining edge 31 and the second retaining edge 32. Therefore, even if a small amount of dirt such as hair continues to move toward the two ends of the roller brush body 1 after passing through the reflux portion 21, it is still difficult to completely enter the end axis area of the roller brush body 1 due to the obstruction of the serpentine channel formed by the first retaining edge 31 and the second retaining edge 32. After being blocked by the serpentine channel, it returns to the middle area of the floor brush body again under the action of the reflux portion 21.

In some embodiments, the reflux portion 21 can be disposed on the end cover 4, the end cover 4 has a mounting edge 41 extending toward the middle of the roller brush body 1, and the reflux portion 21 is sequentially disposed on the mounting edge 41. The first retaining edge 31 is disposed on the outer side of the end cover 4 away from the roller brush body 1. Accordingly, a connection cover 5 partially covering the end cover 4 is disposed, and the second retaining edge 32 is disposed on one side of the connection cover 5 close to the roller brush body 1.
