Abstract
Description
Technical Field
[0001] This utility model relates to the field of spray painting technology, specifically a handheld spray painting device. Background Technology
[0002] A paint gun is a tool used for spraying paint on surfaces and is a type of coating equipment. It works by using compressed air to atomize paint into fine droplets, which are then sprayed onto the surface of the object being coated. It mainly consists of a nozzle, spray cap, needle valve, and gun body, and requires an external air pressure device, such as a pressure tank, pressure vessel, or pump. Compared to traditional manual painting, paint guns are more efficient, produce better results, and are 5-10 times more effective. They also produce a finer, smoother, and more uniform coating. Current handheld paint sprayers require an air pump, necessitate carrying more equipment during operation, impacting user experience, and offer poor product protection. Therefore, we have made improvements and proposed a handheld paint sprayer. Utility Model Content
