The invention discloses a colored drawing spray gun which comprises a hollow gun body, a water absorption rod core and a pigment tube, wherein the middle of the gun body is humped on the radial direction to form an encircling airway, and a switch hole and an air inlet hole are respectively formed in the side wall of the encircling airway; the front segment of the gun body is drilled to form a nozzle, and the water absorption rod core is mounted at the nozzle in the gun body; the tail end of the water absorption rod core extends into the pigment tube with the closed front end and makes contact with the top end of a pigment rod core in the pigment tube, and the pigment tube is formed by mutually combining and connecting a front tube sleeve and a rear tube sleeve; a gap for enabling gas to flow is formed in the connecting and overlapping position of the front tube sleeve and the rear tube sleeve, and the outer side wall of the front tube sleeve is fitted and sealed with the inner wall of the hollow gun body through a seal ring; a liquid pressurization opening is formed in the bottom end of the pigment rod core. According to the technical scheme, the pigment of the pigment rod core in the pigment tube can be pushed forwards to the water absorption rod core through an airflow path, and liquid pigment on the water absorption rod core is atomized and sprayed out under the air pressure action, so that the high atomization effect of pigment is realized. As gas is pushed from back to front, the pigment can be gradually consumed and cannot deposit at the rear part of the pigment tube, and the usage of the pigment is greatly reduced.
Description
technical field [0001] The invention belongs to the technical field of spray-painting tools in pattern spray-painting production, and in particular relates to a color-painting spray gun used by children, primary and middle school students, and spray-painting enthusiasts. Background technique [0002] An airbrush gun is a tool for painting and coloring by spraying liquid paint into mist or atomization. There are many types of common spray painting guns on the market, among which the spray painting tools for children and students are more diverse. Existing spray painting gun structure usually comprises a shell, and air inlet hole, shower nozzle and control valve are arranged on the shell. When in use, the paint is encapsulated in the shell, and the air inlet is connected to the external compressed air. By switching the control valve, the liquid paint in the shell can be sprayed from the spray hole by the compressed air to achieve the spraying effect. Because the traditional ...
