As shown in fig. 1, 2 and 3, according to the embodiment of the present invention, a rolling brush 100 is provided, the main structure of the rolling brush 100 includes a roller 10 and a sleeve 20 sleeved on the roller 10, and the roller 10 and the sleeve 20 are concentrically arranged, so that the sleeve 20 can be stably installed on the roller 10 and can stably rotate along with the roller 10, the outer wall of the roller 10 is provided with a bristle brush assembly 30, bristles in the bristle brush assembly 30 are distributed on the roller 10 at intervals along the length direction and the circumferential direction of the roller 10, the sleeve 20 is detachably sleeved on the roller 10, the outer wall of the sleeve 20 is provided with a bristle brush assembly 40, the bristle brush assembly 40 is distributed on the sleeve 20 along the length direction and the circumferential direction of the sleeve 20, the rolling brush 100 can both deeply clean a carpet or other soft material surface to be cleaned through the bristle brush assembly 30, the surface of the hard material to be cleaned, such as the ground, can be cleaned by the soft brush assembly 40, so that the application range of the rolling brush 100 is improved, and the user does not need to manually replace the hard brush assembly 30 and the soft brush assembly 40 according to the use environment.

The embodiment of the utility model provides a major structure of round brush 100 comprises cylinder 10 and sleeve 20, before equipment round brush 100, at first sets up the scrubbing brush subassembly 30 of round brush 100 on cylinder 10, sets up the scrubbing brush subassembly 40 of round brush 100 on sleeve 20, then overlaps the scrubbing brush subassembly 40 and sleeve 20 together and establish on cylinder 10 to this packaging efficiency who improves scrubbing brush subassembly 30 and scrubbing brush subassembly 40. Specifically, the bristle brush assembly 30 is disposed on the drum 10 by implantation, thereby increasing the strength of the connection between the bristle brush assembly 30 and the drum 10, so that the bristle brush assembly 30 does not fall off from the drum 10 when deeply cleaning the carpet, and the bristle brush assembly 40 is disposed on the sleeve 20 by bonding, thereby increasing the assembly efficiency between the bristle brush assembly 40 and the sleeve 20.

It should be noted that the soft brush assembly 40 provided in the embodiment of the present application may be configured to cover the outer wall of the sleeve 20 as a whole, and may also be configured to cover a partial area of the outer wall of the sleeve 20, in the case that the soft brush assembly 40 covers the outer wall of the sleeve 20 as a whole, the soft brush assembly 40 includes a pile assembly (in fig. 1 and 2, since the structure of the pile assembly is similar to that of the sleeve 20, a clear boundary between the pile assembly and the sleeve 20 is not shown in the drawings), which includes an adhesive layer and piles disposed on the adhesive layer, the piles are adhered to the outer wall of the sleeve 20 by the adhesive layer, and when the roller brush 100 is in an operating state, the pile assembly can be adapted to different cleaning surfaces in cooperation with the hard brush assembly 30.

Further, according to the embodiment of the present invention, the distance between the radially outer end of the soft brush assembly 40 and the radially outer end of the bristle brush assembly 30 from the central axis of the drum 10 is the same (it should be noted that, in fig. 1 and 2, the radially outer end of the soft brush assembly 40 and the radially outer end of the bristle brush assembly 30 are not in a flush state due to the problem of the view angle).

In this embodiment, set up to be the same with the radial outer end of scrubbing brush subassembly 30 through the radial outer end with scrubbing brush subassembly 40, can reduce the influence each other between scrubbing brush subassembly 40 and the scrubbing brush subassembly 30, namely, under the state that round brush 100 is placed in water, the radial outer end of scrubbing brush subassembly 40 flushes with the radial outer end of scrubbing brush subassembly 30, when the face is waited to clean in the round brush 100 cleanness, scrubbing brush subassembly 40 and scrubbing brush subassembly 30 simultaneously with wait to clean the face contact, when waiting to clean the face for the carpet, scrubbing brush subassembly 30 stretches into and carries out the degree of depth clearance in the carpet, when waiting to clean the face for ground, scrubbing brush subassembly 30 and scrubbing brush subassembly 40 clear up ground simultaneously.

According to an embodiment of the present invention, the bristle brush assembly 30 extends from one end of the drum 10 in a twisted state to the other end of the drum 10, and the opening 21 in the sleeve 20 extends from one end of the sleeve 20 in a twisted state to the other end of the sleeve 20 and corresponds to the bristle brush assembly 30.
