A first flat pad 15 and a second flat pad 2 are sleeved on the outer side of the rotating shaft 1. A plurality of brush disc assemblies 3 are sleeved on the rotating shaft 1 between the first flat pad 15 and the second flat pad 2. Each brush disc assembly 3 includes a U-shaped inner ring 5, and radially outwardly extending brush clusters 16 are installed inside the U-shaped inner ring 5. The rotating shaft 1… A central water hole 11 is provided along the axial direction inside. Several radial water holes 13 connected to the central water hole 11 are provided on the side wall of the rotating shaft 1 at positions corresponding to the U-shaped inner ring 5. A hollow groove 7 is provided on the side wall of the U-shaped inner ring 5. By setting up a multi-layer brush disk assembly 3, the distribution of the brush clusters 16 of the entire brush head is made more uniform. By setting up the central water hole 11, radial water holes 13 and hollow groove 7, water can be sprayed from the inside to the outside of the brush clusters 16 while the rotating shaft 1 is rotating at high speed, thereby improving the polishing or cleaning effect.

[0019] Specifically, each brush disc assembly 3 is a separate component that can be stacked together during installation. The length of the brush clusters 16 of different brush disc assemblies 3 can be different. For example, in a total of four brush disc assemblies 3, the length of the brush clusters 16 of the top and bottom brush disc assemblies 3 is greater than the length of the brush clusters 16 of the middle two brush disc assemblies 3.

[0020] In use, the rotating shaft 1 is connected to the main shaft of the power unit. The power unit can be connected to an external water source, which can be directly connected to the main shaft and enter the central water hole 11. There are many types of power units available on the market, and existing power units can also be improved. The diameter of the central water hole 11 is larger than the diameter of the radial water holes 13. Multiple radial water holes 13 can be set on the same transverse section of the rotating shaft 1. The number of hollow grooves 7 is the same as or more than the number of radial water holes 13 on the same transverse section.

[0021] In this embodiment, as Figures 2-3 As shown, the radial water hole 13 is located between the upper and lower adjacent U-shaped inner rings 5, and the hollow groove 7 is located on the upper and lower end faces of the U-shaped inner ring 5 corresponding to the radial water hole 13.
