The roller brush drive assembly 2 is placed in the roller brush receptacle by the snap 2166 engaging the assembly snap hole 131.
The rolling brush motor 22 is disposed in the rolling brush cavity and is located at one side of the central axis a-a or close to one side of the central axis a-a. The rolling brush motor 22 is close to the central axis A-A of the brush body, when the brush body is lifted, the brush body can be basically in a horizontal state and cannot rotate towards one end, and therefore the phenomenon that the center of gravity of the brush body deviates towards the rolling brush motor due to the fact that the rolling brush motor 22 is located on one side of the brush body is avoided, and when the brush body is away from the ground, the brush body can rotate towards the center of gravity and cannot be kept in a basically horizontal state.
It should be noted that in the present embodiment, the position of the power assisting assembly 25 corresponds to the position of the roller brush motor 22, and is located on the other side of the central axis a-a.
In another possible embodiment, the drum part 31 comprises a front lap comprising a front end 311 and a first lap zone 316 and a rear lap comprising a rear end 312 and a second lap zone 317, and both the front end 311 and the rear end 312 are open-like structures. When the rolling brush 3 is arranged in the rolling brush accommodating cavity and sleeved outside the motor housing 21, the second overlapping area 317 is sleeved outside the second supporting piece 214; when the roller brush 3 is connected to the first end cap 14, the first overlapping area 316 is disposed on the outer side of the first supporting member 144.
The interior of the drum part 31 includes a hollow region 318 and a center of gravity region 319, the center of gravity region 319 is used for balancing the weight of the roller brush motor 22 on the other side of the central axis a-a, the hollow region 318 is located between the second overlap region 317 and the center of gravity region 319, and the center of gravity region 319 is located between the hollow region 318 and the first overlap region 316. The weight of the center of gravity area 319 corresponds to the weight of the roller brush motor 22 in the brush body.
In view of the assembly of the drive strap 24, the inner wall surface of the center of gravity region 319 adjacent to the hollow region 318 is provided with a cavity that is recessed toward the outer wall surface of the center of gravity region 319. The pockets include a drive strap pocket 314 and/or a front baffle pocket 315 located rearward of the drive strap pocket 314.
When the roller brush 3 is placed in the roller brush receptacle, the center of gravity area 319 of the roller brush 3 is placed on one side of the central axis a-a. Because the weight of the center of gravity area 319 is equivalent to the weight of the rolling brush motor 22 and is respectively positioned at two sides of the central axis A-A, the brush body can not rotate or swing left and right along the central axis A-A after leaving the ground, so that the brush body can be kept in a horizontal state, and the problem that the center of gravity of the brush body can be deviated to the side of the rolling brush motor 22 because the rolling brush motor 22 is positioned at one side of the brush body and the brush body can rotate or swing to the position of the center of gravity when leaving the ground, so that the brush body can not be kept in a basically horizontal state is avoided.
