A brush roller structure includes a foam body, a central channel, a microporous area, and through holes. The foam body comprises flow channels formed by interlaced pores, and the pores have an average pore diameter ranging from 300 μm to 500 μm. The central channel is arranged in the foam body and communicates with the flow channels. The microporous area is located on the surface of the foam body, and has micro pores, and the diameter of the micro pores is smaller than the average diameter of the pores in the foam body. The through holes are arranged on the outer surface of the foam body, wherein the depth of the through holes is between 50 μm and 300 μm, and the ratio of the total area of the through holes to the outer surface of the foam body is between 10% and 90%.
Disclosed is a central shaft of cleaning roller, including a shaft body and a hollow inner flow channel disposed in the shaft body, and a plurality of dispersed through holes fluidly-communicable with the hollow inner flow channel arranged on an outer wall of the shaft body, and a plurality of groove structures radially extending around the surface of the outer wall of the shaft body, and the groove structures have protruding end edges protruding from the surface of the outer wall. The central shaft of cleaning roller can be used to provide better adhesion for an interface between a foam material and the outer wall thereof.

Brush roller and its manufacturing method and brush roller mold
A brush roller and its manufacturing method and brush roller mold is provided, the brush roller is manufactured by foaming a gaseous pore filler, while solving the problem of using a solid pore filler foaming method to manufacture the brush roller. In addition, the brush roller of the present invention has a plurality of fluid channels communicating between any adjacent two, and the plurality of fluid channels respectively extend to the surface of the brush roller to form pores to improve the fluid permeability of the brush roller, and in the brush roller manufacturing method of the present invention, after the PVA emulsified solution is cured, the compressive stress under the condition of the predetermined compression ratio can be formed to meet the expected brush roller, and it can be used to brush the circuit substrate.
