In this embodiment, taking the rolling brush assembly as an example for a robot cleaner, the robot cleaner includes a machine body, an air extractor installed on the machine body, a motor, and the anti-winding rolling brush assembly.

Referring to fig. 1 and 5, the anti-wind round brush assembly includes a housing 2 provided with a receiving chamber 201, and a round brush body 3 rotatably installed in the receiving chamber 201 of the housing 2. The motor 1 is fixed on the outer side of the shell 2, and the driving end of the motor is in transmission connection with the rolling brush body 3 and drives the rolling brush body 3 to rotate relative to the shell 2. The housing 2 is provided with an air suction port 202 for communicating the accommodating cavity 201 with an air extractor, a plurality of brushing portions 203 are arranged under the air suction port 202, and the air suction port 202 is located on one side of the brushing portions 203, which is far away from the roller brush main body 3. One end of the brushing part 203 is fixedly arranged on the cavity wall of the accommodating cavity 201 of the shell 2, and the other end of the brushing part protrudes towards the rolling brush main body 3 and is used for brushing or loosening the winding object wound on the rolling brush main body 3.

Alternatively, referring to fig. 6 and 7, the roller brush body 3 includes a roller 301 having a rigid structure and a plurality of brush bars 302 having a flexible structure. The rotating roller 301 is provided with a plurality of T-shaped grooves, and the shape of one side of the brush strip 302 is matched with the T-shaped grooves and is inserted into the T-shaped grooves so as to prevent the brush strip 302 and the rotating roller 301 from loosening; the other side of the brush strip 302 passes through the T-shaped groove and protrudes out of the rotating roller 301 along the radial direction of the rotating roller 301. In some other embodiments, the brush bar 302 may be fixed on the roller 301 in a sleeved manner, which is not limited by the present invention.

Further, bristles 303 for cleaning dust are arranged between the protruding parts of two adjacent brush strips 302. The radial distance d1 from the end face of the brush-out part 203, close to the brush-out part 303, to the axis of the rotary roller 301 is less than the radial distance d2 from the end face of the brush-out part 203, close to the brush bar 302, to the axis of the rotary roller 301 is less than the radial distance d3 from the end face of the brush bar 302, close to the brush-out part 203, to the axis of the rotary roller 301, so that the brush-out part 203 can be in contact with the brush bar 302, but the brush-out part 303 is not scraped.

When the robot cleaner works, the rolling brush main body 3 is driven to rotate by the motor 1, and then the ground is cleaned. In the process of cleaning the ground by rotating the roller brush body 3, the winding object is taken up by the roller brush body 3 and wound on the roller brush body 3. It should be noted that, when the winding is wound on the roller brush main body 3, since the radial distance d1 is less than the radial distance d3, the winding is wound on the brush bar 302 and keeps a certain distance with the bristles 303, so as to prevent the winding from being tightly wound on the surfaces of the bristles 303, which increases the difficulty of cleaning the winding. Further, since the winding is spaced apart from the brush 303, even if the winding cannot be cleaned by the subsequent brushing portion 203, the winding can be cut with scissors without damaging the brush 303.

Note that, during the cleaning by rotating the roller brush body 3: on one hand, the winding object can be taken up by the rolling brush main body 3 and wound on the outer surface of the rolling brush main body 3; on the other hand, the brush removing portion 203 contacts the roller brush body 3 to scrape the roller brush body 3, and further, the entanglement such as hair or thin thread wound around the roller brush body 3 is loosened, and even the entanglement is separated from the roller brush body 3, and the entanglement separated from the roller brush body 3 is finally sucked through the air inlet 202, thereby completing the entire entanglement cleaning operation.

When the winding material rotates with the roller brush body 3, the winding material slides in the brush-off portion 203 in a direction approaching the roller brush body 3, and in this case:

referring to fig. 2, if the surface of the brushing portion 203 contacting with the winding object is a hook surface 2031, the winding object slides on the hook surface, and when the winding object slides to the last hook position, the winding object is easily hooked by the hook position and then separated from the roller brush body 3, and the winding object separated from the roller brush body 3 is sucked into the air suction port 202;

referring to fig. 3, if the surface of the brushing part 203 contacting the winding is an arc curved surface 2032, the winding slides on the arc curved surface 2032, and when the winding slides to the final tip position, a certain hooking effect can be generated on the winding, although the winding is not directly separated from the rolling brush body 3, the winding can be loosened, the winding tightness of the winding is reduced, and the winding can be sucked away by the air suction port 202 after being loosened for many times;

referring to fig. 4, if the surface of the brushing portion 203 contacting the winding is a straight plane 2033, the winding slides on the straight plane 2033, and when the winding slides to the final end position, although the winding does not catch, the winding can be loosened, the tightness of the winding is reduced, and the winding can be sucked away by the air inlet 202 after multiple loosening.

Furthermore, a reinforcing member is further arranged on the side of the brushing portion 203, which faces away from the winding, and the reinforcing member is a reinforcing rib plate 204, so that the structural strength of the brushing portion 203 is improved, and the winding is prevented from breaking the brushing portion 203.

Alternatively, referring to fig. 5, the brush bar 302 comprises a first segment 3021 and a second segment 3022, the first segment 3021 and the second segment 3022 extending in opposite helical directions to form a V-shaped structure, and the connection position of the first segment 3021 and the second segment 3022 is the middle position of the brush bar 302. The radial projecting dimension d4 of the middle position of the brush bar 302 is smaller than the radial projecting dimension d5 of the end position, and the radial projecting dimension of the brush bar 302 gradually decreases from the end positions at both ends to the middle position in the middle. That is, the brush bar 302 has a structure with a low middle part and two high ends. Such a structure facilitates the collection of the hairs wound around the roller brush body 3 from both ends toward the middle. Accordingly, referring to fig. 6 and 7, the arrangement direction of each brushing portion 203 is parallel to the axial direction of the rotating roller 301, and in order to keep each brushing portion 203 contactably connected with the brush bar 302, the radial distance from the brushing portion 203 to the axis of the rotating roller 301 corresponds to the radial protrusion dimension of the brush bar 302, that is, the radial distance from the brushing portion 203 at the middle position to the axis of the rotating roller 301 is smaller than the radial distance from the brushing portion 203 at the end position to the axis of the rotating roller 301, that is, the protrusion distance d6 of the brushing portion 203 at the middle position is larger than the protrusion distance d7 of the brushing portion 203 at the end position.
