The invention relates to the technical field of spraying equipment, in particular to a spraying nozzle. The spraying nozzle comprises a quick connector and a paint cylinder, wherein the two ends of the quick connector can be opened and closed. The paint cylinder is provided with an inner hole. A plurality of cavities used for containing paint are formed in the paint cylinder and distributed in thecircumferential direction of the paint cylinder. Each cavity communicates with an outer wall through hole and an inner wall through hole. The inner wall through holes are located in the inner wall ofthe paint cylinder, and the outer wall through holes are located in the outer wall of the paint cylinder. The spraying nozzle further comprises a color blending box and a second fixing rod. The colorblending box is located below the paint cylinder and fixedly connected with the paint cylinder through the second fixing rod and comprises a color blending box cavity and a cylindrical outer wall. The color blending box is provided with color blending box through holes in one-to-one correspondence with the outer wall through holes. The spraying nozzle further comprises a high-pressure air pipe, acolor change disk and a first fixing rod. The high-pressure air pipe is round and is arranged in the inner hole of the paint cylinder in a sliding fit mode. By adoption of the spraying nozzle, the problem that in the prior art, a nozzle does not have a color blending function is solved.
