[0024] like Figure 1 As shown, the specific structure of this application includes: The housing 1 has a receiving cavity 101 disposed therein. The housing 1 may be in any existing shape. The receiving cavity 101 therein is used to install components such as transmission parts. In order to ensure the stability of components such as the transmission shaft assembly 2, a limit plate may be provided. The limit plate has corresponding grooves thereon to limit the transmission shaft assembly 2 to ensure its stability. The transmission shaft assembly 2 is installed in the accommodating cavity 101. When used later, the transmission shaft assembly 2 cooperates with the output shaft to realize the cleaning work of the brush head; The swing member 3 is installed at the end of the transmission shaft assembly 2. The swing member 3 cooperates with the transmission shaft assembly 2 and drives the brush plate assembly to rotate under the drive of the transmission shaft assembly 2. The brush disc assembly 4 is mounted on the housing 1, and one end of the brush disc assembly 4 extends into the accommodating cavity 101 and is connected to the swing member 3. The brush disc assembly 4 is an existing brush disc assembly, and bristles are arranged on its outer surface. It rotates under the drive of the swing member 3 to complete the cleaning work.

[0025] The innovation of the present application lies in the design of the connection of the brush plate assembly 4, that is, using a swinging piece instead, which can not only reduce energy consumption but also reduce noise.

[0026] Specifically, Figure 2 As shown, the swing member 3 includes: An eccentric rotating member 301 is mounted on the top of the transmission shaft assembly 2; The swing fitting part 302 is connected to the brush plate assembly 4 at one end and movably connected to the eccentric rotating part 301 at the other end; the present application adopts a movably connected form to realize power transmission, which can reduce noise.

[0028] Among them, a matching groove 309 is opened on one side of the turntable 303, and one end of the rotating member 304 is movably arranged in the matching groove 309, that is, a gap is left between the bottom of the matching groove 309 and the end of the rotating member 304, so that the rotating member 304 has enough space to perform forward and backward telescopic movement when the turntable 303 moves.

[0029] The turntable 303 may be an integrally formed part or may be formed by splicing a plurality of parts. Figure 2As shown, the turntable 303 is formed by splicing an upper plate 307 and a lower plate 308. When splicing, a matching groove is left inside for installing the end of the rotating member 304. One end of the rotating member 304 is inside the matching groove. After the upper plate 307 and the lower plate 308 are assembled, the stability can be further guaranteed. At the same time, the inner wall of the matching groove is stepped, and the end of the rotating member 304 is stepped, that is, the end of the rotating member 304 located inside the matching groove is larger in size, and the matching groove is also larger inside and smaller outside, which can prevent the rotating member 304 from escaping from the matching groove.

[0030] The structure of the turntable 303 in the present application is further described.
