Problems solved by technology

[0002] At present, the air spray gun is basically a suction type, and the axis of the inlet of the nozzle body and the axis of the outlet intersect at an obtuse angle, that is, when the compressed air flowing at high speed flows into the air nozzle, a negative pressure flow is formed at the front end of the paint, and the paint in the tank The paint is sucked out, because the compressed air must be large to a certain extent, so the spray gun has a large splash when spraying, and the utilization rate is only 20%-25%, which seriously pollutes the environment, and the paint cannot be atomized many times, resulting in uneven spraying.

Embodiment Construction

[0010] With reference to the accompanying drawings, the air valve 5 and the paint valve 3 are arranged on the same axis. An air passage 7 is provided in the air passage to communicate with the pressure tank 6. The connection between the pressure cover and the pressure tank is a threaded connection. The road applies power to the pressure tank to press the paint, and a part of the air is injected from the air nozzle 1, which can ensure the paint to be atomized three times. There is a ring hole 10 in the middle of the nozzle mouth to atomize the paint for the first time, the second atomization hole is the reverse flattening hole 11 and the protection hole 9, the third atomization hole is a side hole, and the paint mist fan-shaped regulator 4 runs through the air passage, and is made of a sliding core, O-shaped sealing ring and fixed seat, and the sliding core enters and exits to adjust the size of the air flow in the side hole 8, and the 2nd is a paint nozzle.

Abstract

This invention relates to a pressure air injection gun, which is characterized by the following: setting air valve and coating valve on same axis; setting one gas path in air channel connected to the pressure tar; the pressure cover and the pressure tar are connected by screw lines means; exerting power on the pressure tar through one gas path and sending coating materials with part of air exhausted from air spray to ensure three times of atomization on the air spray. The spray mouth is set with ring hole to make first atomization and the second atomization hole is the reverse flat hole and protective hole and the third hole is edge hole.

Description

Technical field: [0001] The invention relates to an air spray gun used in the painting field. Background technique: [0002] At present, the air spray gun is basically a suction type, and the axis of the inlet of the nozzle body and the axis of the outlet intersect at an obtuse angle, that is, when the compressed air flowing at high speed flows into the air nozzle, a negative pressure flow is formed at the front end of the paint, and the paint in the tank The paint is sucked out, because the compressed air must be large to a certain extent, so the spray gun has a large splash when spraying, and the utilization rate is only 20%-25%, which seriously pollutes the environment, and the paint cannot be atomized many times, resulting in uneven spraying. The texture is not aesthetically pleasing. Invention content: [0003] The technical problem to be solved by the present invention is to provide a pressure-fed air spray gun which improves the paint utilization rate of air sprayi...
