[0033] In the description of the present application, unless otherwise explicitly limited, the words such as setting, installing, connecting, etc. should be understood in a broad sense, and the person skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical scheme.

[0034] In the related art, the paint spraying machine is a device used in the production process of some objects to spray paint to the side surface of the objects. After the paint is sprayed to the surface of the objects, the paint on the surface needs to be dried before the next operation. Generally, the objects are naturally placed to dry after the paint is sprayed. The existing paint spraying machine is generally provided with a water curtain mechanism and a water tank 500. When the paint is sprayed to the objects, the water curtain mechanism can generate a water curtain covering the inner wall of the paint spraying machine. The water curtain flows into the water tank 500 to be collected. The odor generated by the paint in the paint spraying machine enters the water tank 500 along with the flow of the water curtain, and then is directly discharged into the air, affecting the air quality of the environment around the paint spraying machine.

[0035] Referring to Figures 1 to 5 According to the paint spraying machine, the water tank 500 is provided with the air purification assembly 600. The air purification assembly 600 can purify the odor generated by the paint in the water tank 500, so that the odor in the water tank 500 can be prevented from directly escaping into the air, thereby ensuring the air quality of the environment around the paint spraying machine and being more environmentally friendly.

During the paint spraying process, part of the paint sprayed by the paint spraying mechanism is not attached to the surface of the objects. The water curtain generated by the water curtain mechanism can carry away the paint not attached to the surface of the objects. The water curtain flows into the water tank 500 through the drain port 102, and then enters the water tank 500. After that, the water pump in the pump body assembly in the water tank 500 enters the water curtain mechanism to continue generating the water curtain. Since the air purification assembly 600 is arranged in the water tank 500, the air purification assembly 600 can purify the odor generated by the paint in the water tank 500, so that the odor in the water tank 500 can be prevented from directly escaping into the air, thereby ensuring the air quality of the environment around the paint spraying machine and being more environmentally friendly.
