AI Technical Summary
Existing spray guns have difficulty spraying evenly or cannot spray at all when the liquid volume is small, especially the liquid at the bottom of the container is difficult to be sucked up, resulting in uneven spraying or inability to use.
A rotatable base is installed on the outer side of the bottom of the spray gun. The suction tube is driven by a drive mechanism, which tilts the spray gun and rotates the base when there is less liquid, thereby driving the suction tube to the area where the liquid is concentrated, so as to achieve uniform spraying.
When there is little liquid, by tilting the spray gun and rotating the base, the suction tube can be effectively moved to the area where the liquid is concentrated, ensuring smooth spraying and solving the problem of uneven spraying.
