Tilted Spray Gun Body for Efficient Liquid Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray guns face inefficiencies in liquid feeding, waste of resources, and operational inconvenience due to parallel arrangement of components, leading to residual liquid contamination, incomplete liquid usage, and difficulty in spraying high positions.
Innovation Solution
A spray gun design with a tilted gun body and a liquid container featuring a feeding hole on the lid, connected by a hollow pipe, allowing efficient liquid feeding without replacing the container and enabling one-handed adjustment of spray parameters for improved usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the gun body is arranged in parallel with the liquid container for convenience of alignment, then the ease of manufacture and assembly is improved, but the residual liquid contaminates the operating environment and resources are wasted
Solution Approach 1:
The gun body is tilted at an angle of 15-45 degrees relative to the liquid container, breaking the parallel symmetric arrangement. This asymmetric tilt causes residual liquid to flow toward the rear of the gun body due to gravity, preventing contamination and enabling complete liquid usage.
2Productivity
If a liquid feeding hole is provided on the lid body of the liquid container to improve liquid feeding efficiency, then the liquid feeding speed is improved, but the gun body blocks the feeding hole and sealing becomes difficult
Solution Approach 1:
The liquid feeding hole is positioned on the lid body at a location that is not directly above the gun body when tilted. The tilted arrangement creates vertical clearance between the gun body and the feeding hole position, allowing feeding operations to proceed without blockage while maintaining sealing effectiveness.
3Stability of the object's composition
If the spray gun is held horizontally for stable operation, then the stability of operation is improved, but residual liquid drops and contaminates the environment
Solution Approach 1:
The tilted gun body arrangement uses gravity as a counterbalancing force. When held horizontally, the tilt angle causes residual liquid to flow toward the rear of the gun body rather than dripping forward, effectively using gravitational force to prevent contamination while maintaining operational stability.
4Quantity of substance
If the tube reaches the bottom of the liquid container to maximize liquid usage, then the quantity of substance utilization is improved, but the tube cannot reach the liquid level when liquid is insufficient
Solution Approach 1:
The tilted gun body arrangement dynamically adapts to varying liquid levels. As liquid is consumed and the level drops, the tilt angle ensures the tube maintains contact with the liquid surface throughout the entire usage cycle, preventing air intake and ensuring complete liquid extraction until the container is empty.

AI summary
The present invention discloses a spray gun, which comprises a gun body; a liquid container surface disposed below the gun body; a hollow connecting pipe disposed between the gun body and the liquid container. The liquid container is in communication with the interior of the gun body through the hollow connecting pipe; the liquid container has a liquid feeding hole on the top; the head portion of the gun body is located above the top of the liquid container and tilted downwardly away from the top of the liquid container. In the present invention, there is a relatively large space above the liquid feeding opening, providing an efficient space for a smooth liquid feeding operation. Liquid feeding can be performed inside the liquid container without replacing the liquid container and the liquid is ensured not to be split during the operation.
