[0024] The use of energy-saving and environmentally friendly wall painting machines for home decoration also includes;
[0025] S1: When painting the wall surface, the first and second plastering panels are parallel, and the first and second powder collection boxes are parallel. The moving device makes the first and second powder collection boxes abut against the wall. Then, the feeding pump delivers powder between the first plastering panel and the wall.

[0028] 1. When painting the inside corner, the driving component drives the second plastering panel to rotate around the hinge axis, compressing the first sector-shaped corrugated plate. This causes the beveled ends of the first and second plastering panels to abut against each other, forming an L-shape.

Furthermore, by rotating the second plastering panel, the angle between it and the first plastering panel can be changed, enabling the painting of flat walls, inside corners, and outside corners. This improves the painting quality and efficiency of inside and outside corners.
