AI Technical Summary
Existing high-pressure water guns are prone to water hammer during startup or shutdown, which can damage the internal structure and affect the stability and lifespan of the equipment. Existing buffer valves or water circuit designs are complex in structure and have slow response or limited shock absorption.
A swingable limit rod is set on the water gun trigger, and a shock-absorbing block is installed on the limit rod. The impact force is absorbed through inertial offset and damping system to reduce vibration transmission. Combined with the elastic coating layer, a damping system is formed to achieve rapid response and effective buffering.
It effectively mitigates the impact of water hammer on the water gun mechanism, extends its service life, improves user comfort and stability, and features a simple structure and rapid response.
