Top surface paint roller brush
The invention discloses a top surface paint roller brush, and aims at providing the top surface paint roller brush with the advantages that the directional material supply can be realized; the brushing is uniform; and paint cannot easily drip or leak. A roller is arranged in a brush tube; a material storage cavity is arranged in the roller; penetrated material discharge holes are densely distributed in the roller wall of the roller; each of the two ends of the roller is provided with a fixing ring and an end cover; a shaft hole is formed in the center position of each end cover; a center shaft is a hollow shaft; the center shaft is positioned at the inner side of the end covers and is provided with a plurality of air outlet holes in the longitudinal direction; a step shaft is arranged in each of opposite positions of the inner side of a center hole of each end cover; an air flow guide sleeve with the C-shaped cross section and an upward opening is formed in the excircle of each step shaft in an adaptive way; each of the two ends of an upward C-shaped opening of each air flow guide sleeve is provided with a guide plate; each guide plate is in a horn mouth shape; and the lower end of each air flow guide sleeve is provided with a heavy bob. During brushing by rotating the roller, air is blown to the top surface after passing through horn mouths; the paint forms directional supply; the sagging caused by excessive material supply is avoided; the brushing is more uniform; and meanwhile, the paint cannot easily drip or leak.
