[0008] Preferably, in order to improve the movement followability of the paint canister, moving wheels are provided at the four corners of the lower end of the paint canister to facilitate the movement of the paint canister and to adjust its position according to the application position.
[0009] Preferably, some repair locations may require climbing a ladder for painting, and the area is not large, so using the paint barrel appears clumsy. Therefore, the present application also includes a portable paint bin that can be detachably fixed to the extension rod, and the internal cavity of the portable paint bin is used to store paint. The upper end of the portable paint bin is provided with a feeding port and the lower end is provided with a threaded port that is threadedly connected to the lower end of the suction hose, which is more convenient to use.
[0010] Preferably, a handle is fixedly mounted on the lower end of the extension rod for easy holding.
[0011] The advantages and positive effects of the utility model are:
[0012] 1. It can be held with both hands for application, and the sponge application roller can drive the mechanical peristaltic pump to extract the paint while rotating. There is no need to repeatedly dip the paint into the bucket, which greatly reduces dripping and improves efficiency.
[0013] 2. And because the transmission ratio of the mechanical peristaltic pump driven by the rolling of the sponge application roller is stable, the amount of paint extracted is uniform and stable, which makes it more uniform and convenient when applying. The traditional dipping method will have more paint when it is just dipped, and the paint will decrease sharply after a few strokes on the wall. In this case, workers need to control the uniformity of the application based on experience. BRIEF DESCRIPTION OF THE DRAWINGS
