Abstract
The invention provides a high-pressure water gun, belongs to the technical field of high-pressure water guns and solves the problems that the existing high-pressure water gun is large in trigger pull resistance and easy to damage. The high-pressure water gun comprises a water gun body. A control valve, a high-pressure inlet passage and a high-pressure outlet passage are arranged in the water gun body, wherein the high-pressure inlet passage and the high-pressure outlet passage are communicated with a cavity of the control valve. The high-pressure inlet passage is communicated with an inlet passage of a handle, and the high-pressure outlet passage is communicated with an outlet passage of a spray pole. A trigger is fixedly hinged to the water gun body. A valve stem of the control valve extends out of the water gun body and is abutted to the upper end of the trigger. After the trigger is pulled, the valve stem drives a spool to communicate the high-pressure inlet passage with the high-pressure outlet passage. A decompression water passage for controlling the control valve is reserved in the water gun body. The high-pressure water gun has the advantages that the service life of the high-pressure water gun is prolonged, the high-pressure water gun is more stable to use, and usage cost is reduced.
