When the rolling brush sleeve 70 is mounted in the mounting cavity 11, if the limiting portion 72 is not provided, the edge of the rolling brush sleeve 70 is contracted into the mounting cavity 11 by torque, and the cavity opening of the mounting cavity 11 becomes smaller, so that the rolling brush sleeve 70 is difficult to be sleeved on the rotating shaft 60.

In this embodiment, the rolling brush sleeve 70 is provided with a sleeve cavity, and the shape of the sleeve cavity is fitted to the shape of the rotating shaft 60, thereby improving the transmission efficiency.

Furthermore, the installation cavity 11 of the roll brush body 10 and the roll brush sleeve 70 may be manufactured with mutually matched molds to facilitate better connection of the two.

In addition, an anti-collision gap 80 is arranged between the limiting part 72 and the cavity bottom of the accommodating cavity 21, and because the rolling brush body 10 can shake in the cleaning process, the number of collisions between the rolling brush body 10 and the cavity bottom of the accommodating cavity 21 is reduced by arranging the anti-collision gap 80, so that the abrasion to the rolling brush body 10 and the accommodating cavity 21 is reduced.

The utility model also provides a cleaning robot which comprises the rolling brush device 100 and a robot main body, wherein the rolling brush device 100 is arranged on the robot main body. Namely, the cleaning robot has the above beneficial effects and will not be described herein.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; the technical features of the above embodiments or in the different embodiments may also be combined within the idea of the utility model, the steps may be implemented in any order, and there are many other variations of the different aspects of the utility model as described above, which are not provided in detail for the sake of brevity; while the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
