Spray Gun Pipe Adapter With Snap Clamp for Sealed Quick Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional high-pressure cleaning devices face challenges with unreliable connections between water pipes and spray guns due to sealing issues, difficulty in disassembly, high production costs, and compatibility problems between differently sized components from various manufacturers, limiting their use in both commercial and household applications.
Innovation Solution
An adapter with a connection assembly, clamping assembly, and covering member that includes a chute with grooves and tapered regions, allowing for secure coupling and easy disconnection of water pipes and high-pressure spray guns through a snap coupling mechanism, which accommodates varying sizes and standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If copper threads are used to connect the spray gun and water pipe, then the connection is firm, but the sealing problem is difficult to solve, disassembly is troublesome, and production cost is high
Solution Approach 1:
The connector is divided into separate components: a connector body with external threads, a separate sealing ring, and a spray gun interface. This segmentation allows the sealing function to be independent from the structural connection, enabling easy disassembly while maintaining both connection strength and sealing effectiveness.
2Strength
If copper threads are used to connect the spray gun and water pipe, then the connection is firm, but the sealing problem is difficult to solve, production cost may be very high
Solution Approach 1:
The sealing ring is designed as a separate, replaceable component that can be easily manufactured from inexpensive materials. This allows the sealing function to be achieved with low-cost materials while the main connector body provides the structural strength, significantly reducing production costs compared to using expensive copper threads for both connection and sealing.
3Device complexity
If metal water pipe head is directly inserted into high-pressure spray gun via threaded connection, then the connection is simple, but sealing reliability is insufficient under high pressure
Solution Approach 1:
A separate sealing ring is introduced as an intermediary element between the threaded connection components. This sealing ring mediates the connection by providing a dedicated sealing surface that maintains reliability under high pressure, while the overall connection structure remains simple and easy to assemble.

AI summary
An adapter for connecting a water pipe and a high-pressure spray gun includes a connection assembly, a clamping assembly, and a covering member. The connection assembly includes a connector body defined by a side wall and extending between a proximal end and a distal end, and a chute that extends along the connection body between the proximal and distal ends. The water pipe is coupled along the proximal end and the spray gun is coupled along the distal end. The chute includes grooves, and tapered regions seamlessly extending below from the grooves. The clamping assembly is operatively coupled to the connector body. The covering member sleeves over the connection assembly to movably engage with the clamping assembly, and is pressed and released to realise the buckle to move down from the grooves towards the tapered regions and back from grooves to the tapered regions, to clamp the water pipe.
