Specifically, as shown in fig. 4 and 5, the roll brush holder 100 may include a side bracket 110, and a cantilever bracket 120 protruded on the side bracket 110. The drive structure 300 may include a drive motor 310, a transmission structure 320 coupled to the drive motor 310, and a drive shaft 330 coupled to the transmission structure 320. The driving motor 310 and the transmission structure 320 may be disposed on the side bracket 110, i.e., the driving structure 300 may be supported from the side by the side bracket 110 of the roll brush holder 100. Furthermore, the driving shaft 330 is rotatably disposed on the cantilever 120 along the extending direction of the cantilever 120, that is, the driving shaft 330 is rotatably disposed on the cantilever 120, so that the driving shaft 330 is in a suspended state like the cantilever 120, and the driving shaft 330 can be supported by the cantilever 120, so that the driving shaft 330 is stably rotated on the cantilever 120 under the driving of the driving motor 310 and the transmission structure 320, thereby reducing or avoiding the shaking of the suspended driving shaft 330.

The coupling structure 400 may include a first coupling member 410 provided at an end of the driving shaft 330, and a second coupling member 420 provided at the cleaning roller brush 200, the first coupling member 410 being detachably coupled to the second coupling member 420. The cleaning roller brush 200 is coupled to the driving shaft 330 by the first and second coupling members 410 and 420, so that the cleaning roller brush 200 is rotated by the driving shaft 300. Also, the cleaning roller brush 200 is rotatably fitted over the cantilever holder 120 and the driving shaft 330, so that the cleaning roller brush 200 is supported by the cantilever holder 120 from the inside in a cantilever manner.

By using the cantilever bracket 120 of the rolling brush holder 100 to cantilever the cleaning rolling brush 200 and the driving shaft 330 of the driving structure 300, the cleaning rolling brush 200 can be supported from one end, so that the other end (suspended end) of the cleaning rolling brush 200 can be directly contacted with the surface to be cleaned, and the cleaning rolling brush 200 can achieve extreme dust removal while reaching. Moreover, the cantilever support 120 connected to the side support 110 can stably support the driving shafts 330 of the cleaning roller brush 200 and the driving structure 300, so that the driving shafts 330 of the cleaning roller brush 200 are not easy to shake in the working process, thereby ensuring the cleaning effect and improving the user experience effect.

Also, the side bracket 110 and the outrigger 120 may be integrally provided or detachably provided rigid brackets. The rolling brush holder 100 formed by the side bracket 110 and the cantilever bracket 120 is configured as a rigid bracket, so that the overall supporting stability is better, the rigid supporting effect on each driving shaft 330 of the cleaning rolling brush 200 is better, and the shaking of each driving shaft 330 of the cleaning rolling brush 200 in the working process can be further reduced. Furthermore, the cantilever support 120 and the side support 110 can be connected in a detachable connection manner such as a snap connection, a screw connection, or a threaded connection; further, the cantilever holder 120 and the side holder 110 may be integrated by welding, caulking, integral processing, or the like.

The side bracket 110 and the arm bracket 120 are made of metal having high strength, and the driving shafts 330 of the cleaning roller brush 200 are supported more stably and reliably. Specifically, the side bracket 110 and the arm bracket 120 may be both made of a metal bracket such as a steel bracket or an aluminum alloy bracket. The side bracket 110 made of metal and the arm bracket 120 made of metal may be integrally connected by welding.

Also, the length value of the cantilever holder 120 may be equal to or greater than one-half of the length value of the cleaning roller 200, and may be equal to or less than the length value of the cleaning roller 200. That is, the length of the cantilever support 120 is at least half of the length of the cleaning roller brush 200, so that the supporting length of the cantilever support 120 to the cleaning roller brush 200 is longer, the completely suspended length of the cleaning roller brush 200 is relatively shorter, and the possibility of shaking of the cleaning roller brush 200 can be reduced; moreover, the length value of the cantilever holder 120 does not exceed the length value of the cleaning roller brush 200, so that the cantilever holder 120 does not protrude out of the cleaning roller brush 200 and the cleaning effect of the cleaning roller brush 200 is not affected.

In addition, the connection limit of the bracket rotating support bearing 132 and the rigid bracket barrel 122 can also be realized through a movable clamping mode. At this time, the cantilever support 120 may include a limiting sleeve 124 sleeved on the rigid support barrel 122, the support rotation support bearing 132 may be movably sleeved on the rigid support barrel 122, and the inner side surface of the support rotation support bearing 132 may abut against one end surface of the limiting sleeve 124, and the outer side surface of the support rotation support bearing 132 may abut against other structures (such as the side support 110 or the end cover structure), so as to realize connection limiting of the support rotation support bearing 132.
