Wall paint roller brush for feeding in fixed direction

Abstract

The invention discloses a wall paint roller brush for feeding in a fixed direction, and aims at providing the wall paint roller brush which can conduct feeding in the fixed direction and is uniform in painting and not prone to paint leakage. A roller is arranged in a brush cylinder. Through discharge holes are densely distributed in the cylinder wall of the roller. The two ends of the roller are each provided with a fixing ring and an end cover. A shaft hole is formed in the center of each end cover. A central shaft is a hollow shaft. A plurality of air outlets are longitudinally formed in the portion, inside the end covers, of the central shaft. The opposite positions of the inner sides of the central holes of the end covers are each provided with a step shaft. An air flow guide sleeve with the section opened in a C shape is arranged on the outer circle of each step shaft in a matched manner. The two ends of the C-shaped opening of each air flow guide sleeve are each provided with a guide plate. The guide plates are each in a horn mouth shape. A heavy hammer is arranged at the lower portion of each air flow guide sleeve. When the roller is rotated to conduct painting, air is blown onto a wall after passing through horn mouths, paint is fed in the fixed direction, sagging caused by a too large feed amount is avoided, painting is more uniform, and meanwhile the paint is not prone to leakage.
