The working principle of the invention is as follows:
when the high-pressure pump is used for supplying water, the high-pressure water enters the water inlet channel 2, and the pressure regulating knob 6 is regulated, so that the compression degree of the large spring 17 and the small spring 18 is regulated, the rated pressure is regulated, the spray gun is opened, the water outlet cone valve 26 is propped open by the high-pressure water, and the water is sprayed out of the spray gun through the water outlet channel 4. In the process of rotating the pressure regulating knob 6, the large spring 17 and the small spring 18 press the steel ball seat 16 to press the steel ball 14 to the water return valve seat 8 for hard sealing, high-pressure water is controlled to flow back, and when the steel ball is pressed down, the valve core 12 is pushed, meanwhile, the valve core pressing seat 10, the spring pressing piece 23 and the valve core spring 21 are pushed down, so that the bottom of the valve core 12 presses down the spring piece 11a of the touch switch 11 to open the touch switch, and a switch passage is formed. At this time, the pressure born by the steel ball and the thrust born by the valve core pressing seat are in a balanced state, so that the pressure of the water outlet is stable.
When the spray gun for discharging water is closed, the water outlet cone valve 26 seals the water outlet cone valve pressure with the inclined plane of the cylinder body 1 under the action of the elasticity of the cone valve spring 25, high-pressure water reaches the inside of the switch seat 20 through the process hole 4a, because the stress area of the valve core pressing seat 10 is larger than the stress area of the steel ball 14, when the pump continues to run after the gun is closed, the internal pressure raises the valve core pressing seat 10 to bear upward thrust force towards the steel ball 14 and is larger than downward thrust force of the steel ball, the valve core pressing seat 10 is pushed upward, the valve core 12 is pushed simultaneously, the steel ball is separated from the water return valve seat 8, water in the cylinder body 1 flows to the water return channel 3 from the hole in the middle of the water return valve seat 8, the inside of the pump is decompressed, and when the valve core 12 is pushed upward, the tail part is separated from the spring piece 11a of the touch switch 11, so that the touch switch is opened.
When the spray gun is opened again, the water in the cylinder body 1 pushes the water outlet cone valve 26 away the water inlet channel 2 to be equal to the pressure of the switch seat 20, the steel ball 14 is pressed to the water return valve seat 8 again to carry out hard sealing, a high-pressure pushing valve core is formed to push down the spring piece 11a of the touch switch 11 so as to open the touch switch, and the switch passage is enabled to switch the spray gun and simultaneously control the circuit switch.
