Problems solved by technology

The mouth-to-mouth spray gun is easy to operate, especially when spraying a large area of ​​flat surface, the work efficiency is high, but for a small range of motion, or when the part that needs to be sprayed is narrow and long, the use of the mouth-to-mouth spray gun is limited. The sprayed paint mist cannot be concentrated into these narrow parts, which affects the painting operation

Embodiment Construction

[0012] See figure 1 , The composition of the present invention includes a paint cylinder 1, a spray gun handle 8 and a trigger 6, and the upper part of the paint cylinder is provided with a paint nozzle 4 and an air nozzle 5. In order to solve the problem of spraying paint at the slit, the present invention adds a compressed air header 2 and a paint outlet header 3. The compressed air header communicates with the jet nozzle 5, the paint outlet header communicates with the paint outlet nozzle 4, the compressed air header and Corresponding to the port of the paint header. The length of the two additional pipes depends on the needs. The compressed air pipe and the air outlet can be connected by a fixed connection method such as welding, or a detachable connection method, such as a threaded connection, as is the connection between the paint outlet pipe and the paint outlet nozzle. The use of detachable threaded connection can obviously increase the flexibility of the spray gun, ...

Abstract

A spray guy used for spraying paint on a slit belongs to the technology field of blast atomizer, which is used for overcoming the difficulty in paint-spraying on the slit. The spray guy consists of a paint cylinder and a handle. The upper part of the paint cylinder is provided with a painting nozzle and an air nozzle. Particularly, the spray guy is provided with an additional compressed air connecting pipe and an additional paint outlet pipe. The compressed air connecting pipe is communicated with the nozzle. The paint outlet pipe is communicated with the painting nozzle. The compressed air connecting pipe and the paint outlet pipe are extensional flexible pipes, the end positions of which correspond to each other. The compressed air nozzle and the compressed painting nozzle are respectively provided with an additional pipe that has some rigidity and produces plastic deformation easily. When the invention is used, the terminal parts of two pipes can be placed into the slit to spray the paint on the slit of an object. So the slit can be painted evenly. The invention has simple structure and is easy to be implemented. Trial results show that the invention has a good spray-paint effect and overcoming the difficulty in spraying the paint on the slit.

Description

Technical field [0001] The invention relates to a spray gun, which is particularly suitable for spraying paint at the slit, and belongs to the technical field of atomized spraying devices. Background technique [0002] At present, spray guns are often used for painting the surface of objects, which is a quick and convenient operation method. The working principle of the spray gun is powered by manual or motorized mode. The negative pressure is generated at the paint outlet by compressed air, and the paint in the paint cylinder is sucked out. The spray gun is blown into a mist at the compressed air outlet, and the mist paint is dispersed. Adhere to the surface of the sprayed object to form a uniform coating film. In spraying construction, the most widely used is the nozzle spray gun, its structure is like figure 2 Shown. The nozzle-to-nozzle spray gun is easy to operate, especially when spraying a large area of ​​the plane, and the work efficiency is high. However, when the rang...
