[0029] The bottom of the columnar part is communicated with a connecting pipe 9, the bottom of the connecting pipe 9 is bent outward to form a liquid supply pipe, the liquid outlet end of the liquid supply pipe is arranged towards the rolling brush 2, the liquid outlet end of the connecting pipe 9 is provided with an auxiliary groove plate 10, the inside of the auxiliary groove plate 10 is provided with a liquid flow cavity communicated with the liquid outlet end of the connecting pipe 9, when the pull rod 8 is pushed downward, the rotating rod 7 is driven to move downward, the paint in the inside of the bucket body 4 is transported into the connecting pipe 9 through the rubber block 6 in the moving process of the rotating rod 7, the paint flows into the liquid flow cavity in the inside of the auxiliary groove plate 10 through the connecting pipe 9, a plurality of through holes communicated with the liquid flow cavity are arranged on the wall surface of the auxiliary groove plate 10 towards the rolling brush 2, the paint entering into the liquid flow cavity is uniformly distributed on the outer wall of the rolling brush 2 through the through holes, so as to make the rolling brush 2 to perform the uniform brushing work on the ground, the cross section of the auxiliary groove plate 10 is arc-shaped, and the auxiliary groove plate 10 is semi-surrounded on one side of the rolling brush 2, this design makes the auxiliary groove plate 10 to be above the rolling brush 2 when the push rod 1 is inclined to operate the rolling brush 2, and the auxiliary groove plate 10 covers the axial length of the rolling brush 2 in the top view projection.

[0030] Working principle:

[0031] The user first takes up the push rod 1, takes off the plug 5 from the outer wall at the bottom end of the push rod 1, and then inserts the rolling brush 2 and the position of the through hole at the bottom end of the push rod 1 into the inside of the paint bucket, after insertion, the pull rod 8 is pulled upward, the pull rod 8 drives the rubber block 6 to move upward in the inside of the bucket body 4 through the transmission rod 7, when the rubber block 6 moves upward in the inside of the bucket body 4, the negative pressure can be generated in the inside of the bucket body 4, the paint is sucked into the inside of the bucket body 4 through the through hole at the bottom end of the push rod 1, when the rubber block 6 moves upward to the top end of the inner wall of the bucket cover 3, the pull rod 8 is stopped to be pulled, the push rod 1 and the rolling brush 2 are taken out from the inside of the paint bucket, after taking out, the plug 5 is inserted into the through hole in the outer wall at the bottom end of the push rod 1 to seal, after installation, the rolling brush 2 is placed at the position to be brushed to prepare for the brushing work.

[0032] In the process of painting, because the push rod 1 needs to be inclined to use, the position of the auxiliary groove plate 10 is just above the roller brush 2 in the process of inclination, in the process of painting, when the paint on the surface of the roller brush 2 is less attached, the pull rod 8 is pushed downward, and in the process of pushing, the transmission rod 7 moves downward inside the barrel cover 3, and the rubber block 6 is driven to move downward, so that the paint in the barrel body 4 is extruded downward, when the rubber block 6 extrudes the paint downward, the paint is transported to the liquid flow cavity in the auxiliary groove plate 10 through the connecting pipe 9, and then enters the through hole uniformly distributed in the auxiliary groove plate 10 to uniformly drop the paint on the surface of the roller brush 2, when the roller brush 2 surface drops the appropriate paint, the user stops pushing the pull rod 8, at this time the inside of the barrel body 4 is in a negative pressure state, and the paint inside will not continue to flow downward, when the primer needs to be repainted, a certain amount of paint is pre-stored in the barrel body 4, and will not drip during walking, when the primer on the ground needs to be repainted, a certain amount of paint can be pushed out in the cylindrical part and uniformly distributed on the roller brush 2, and the primer is painted and repainted.

[0033] When the painting is completed, the paint adhered in the barrel body 4 needs to be cleaned, the user can rotate the barrel cover 3 to take off the barrel cover 3 from the top end of the barrel body 4, and after taking off, the user can clean the inside of the barrel body 4.
