[0002] The so-called paint is a continuous film that is coated on the surface of an object to be protected or decorated and can form a firm attachment with the object to be painted. It is usually mainly composed of resin, oil or emulsion, with or without pigments and fillers added, and corresponding additives added, and is a viscous liquid prepared with organic solvents or water. When using paint, a paint spray head is required.

[0003] The applicant found through retrieval a Chinese utility model patent with the publication number CN218796791U named "A Paint Spray Head". In this patent, slurry is pumped into each slurry chamber inside the spray head body, and then the slurry flows to the guiding part through the discharge holes.

However, when the above device is actually used, there are some deficiencies. After the spray head of the above device sprays paint, there is often residue inside the spray head. For a spray head that is not used for a long time, the residue paint will harden and cause blockage problems. Based on this, a spray head structure for paint and a spraying device that can solve the above problems are now proposed. Summary of the Utility Model
