Further, the driving parts 1222 are provided with not less than two, and the driving parts 1222 are arranged along the circumference of the connecting part 1221; the axis of the connecting portion 1221 is parallel to the axial direction of the roller brush body 110, and the included angle between the extending direction of the driving portion 1222 and the axial direction of the roller brush body 110 is greater than zero.
In a preferred embodiment of the present invention, each of the driving portions 1222 is located between two adjacent blocking portions 112.
In a specific embodiment of the present invention, with reference to fig. 7, taking the second barrier wall 1122 and the single contact point when the driving portion 1222 contacts as an example, one of the contact points M is selected, at this time, the contact point M is driven by the driving force F1 provided by the driving portion 1222 to form a reaction force F2, and meanwhile, because the second barrier wall 1122 is inclined, the reaction force can be decomposed into orthogonal forces F3 and F4, under the effect of the orthogonal force F3, so that the rolling brush moves towards the locking direction thereof, and finally the rolling brush is self-locked, thereby preventing the rolling brush from loosening or breaking away from, and ensuring the self-locking effect of the rolling brush.
Further, a buffer member (not shown) made of an elastic material is disposed on the outer circumference of the driving portion 1222.
It can be understood that, in the present invention, a buffer is disposed at the periphery of the driving portion 1222, so that the buffer buffers when the driving portion 1222 contacts the first blocking wall 1121 or when the driving portion 1222 contacts the second blocking wall 1122, thereby preventing the driving member 122 and the roller brush body 110 from being damaged, prolonging the service life of the driving member 122 and the roller brush body 110, and reducing the production cost.
It should be noted that the implementation of the buffering between the driving portion 1222 and the first blocking wall 1121 or between the driving portion 1222 and the second blocking wall 1122 is not limited to the arrangement of a buffering member at the periphery of the driving portion 1222, and other common buffering structures, such as the driving portion 1222 made of a flexible material, the periphery of the driving portion 1222 being coated with an outer layer made of a flexible material, or the periphery of the first blocking wall 1121 and the second blocking wall 1122 being coated with an outer layer made of a flexible material, can also implement the buffering effect of the driving portion 1222 and the first blocking wall 1121 and the second blocking wall 1122, and therefore, should also be regarded as a specific embodiment of this solution.
