Description

Technical Field

[0001] This utility model relates to the field of spray device technology, and in particular to a water gun. Background Technology

[0002] In existing technologies, to meet the needs of high-pressure cleaning or spraying specific liquids, corresponding water gun equipment is often configured, allowing workers to hold the gun and precisely spray designated locations. These water guns generally consist of a gun body and a trigger mechanism mounted on it. Workers can hold the gun body and trigger the spraying of fluids such as water by pulling the trigger. The water gun can also be connected to an external pump to provide a sufficiently high-pressure water flow.

[0003] However, the electrical control and water flow sequence design of existing water guns or similar spray devices have significant shortcomings. In particular, when the trigger is pulled, the corresponding circuit of the pump and the water flow inside the water gun are often connected simultaneously, meaning the pump and valve start working at the same time. This results in an unstable water flow output from the water gun at the beginning, and operators are also prone to accidentally spraying water due to slight trigger presses. Utility Model Content
