Spray Gun Air Pressure Regulator for Stable Paint Atomization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spray guns require external air pressure adjustment using meters, which is inefficient and affects painting quality due to high initial compressor pressure ranging from 6 to 8 bars.
Innovation Solution
A method and device for adjusting air pressure within the spray gun, featuring a first and second chamber with an air adjustment valve, a movable part, and a spring, allowing for pre-set pressure adjustment via a knob without external meters, maintaining stable air pressure for consistent spraying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external air pressure adjustment valve and meter are used, then air pressure can be adjusted, but operation efficiency is low and painting quality is affected
Solution Approach 1:
The patent combines the air pressure adjustment function directly into the spray gun by integrating an adjustment valve and regulator mechanism within the gun body. This merging eliminates the need for separate external adjustment equipment, allowing users to adjust air pressure efficiently at the source while maintaining consistent painting quality through precise internal control.
Solution Approach 2:
The patent introduces a regulator mechanism as an intermediary component between the air supply and the spray nozzle. This regulator acts as a mediator that automatically controls and stabilizes the air pressure, ensuring consistent painting quality while simplifying the adjustment process through integrated controls.
2Power
If high air pressure from compressor (6-8 bars) is used, then sufficient spray power is achieved, but painting quality deteriorates
Solution Approach 1:
The patent employs parameter change by transforming the high-pressure air supply (6-8 bars) into a controlled, lower-pressure output suitable for painting. The integrated adjustment valve and regulator mechanism modify the pressure parameter in real-time, maintaining sufficient spray power while preventing quality deterioration through precise pressure control.
Solution Approach 2:
The patent implements dynamic pressure control through the adjustment valve and regulator mechanism, which continuously adapt the air pressure according to painting requirements. This dynamic adjustment ensures optimal spray power is delivered while maintaining consistent painting quality, unlike static high-pressure systems.

AI summary
A device for adjusting air pressure of a spray gun (1), and a method for adjusting air pressure of a spray gun (1) includes installing an air adjustment valve (3) in a first chamber (24) located at the rear end of a rear path (22) of the spray gun (1). The spray gun (1) is connected with a compressor and the users operates the air adjustment valve (3) to reduce the pressure in the first chamber (24), and the second chamber (27) is supplied with a pre-set pressure so as to stably provide constant pressure to the front path (21) to proceed paint spraying task.
