Description

An environmentally friendly hand-held paint spraying device

technical field

The utility model relates to the technical field of painting equipment, in particular to an environment-friendly hand-held painting device.

Background technique

The spray gun is a tool for spraying paint, which is used for surface treatment of products. It is a kind of coating equipment. It atomizes the paint into fine paint droplets through compressed air, and sprays it on the surface of the object under the drive of the air flow. Composed of cap, nozzle, needle valve and gun body, at the same time, it needs to be connected to the external air pressure device, such as pressure tank, pressure barrel, pump and so on. Compared with the traditional manual painting, the spray gun is more time-sensitive and more beautiful, and the efficiency is 5-10 times higher than that of brushing, and the coating film is fine, smooth and uniform.

The Chinese patent (authorized announcement number: CN211636993U, authorized announcement date: 2020.10.09) proposes an environmentally friendly painting equipment for the production of leisure wooden chairs. The patent puts the adjusted paint in the lower pot, and then puts the lower pot Installed on the paint inlet interface, turn the rotating block so that the rotating block moves to the right through the threaded through hole and the threaded rod, and then slide the connecting block so that the connecting block moves upward through the sliding connection between the sliding block and the slide rail until The metal bin moves to contact with the bottom of the lower pot, and the top magnet is affected by the magnetic force of the bottom magnet, so that the top magnet rotates to be parallel to the bottom magnet, and the rotating block is reversely rotated so that the rotating block contacts the support plate.

However, during the use of the above-mentioned patent paint spray gun, the scattered paint is easy to fall on the operator behind the paint spray gun, which directly affects the human body, and the paint will partially rebound after being blocked by the spray paint, and will directly adhere It is not easy to clean the arms of the workers, and it is not good for the skin. Therefore, we propose an environmentally friendly handheld paint spraying device.
