In this embodiment be equipped with the annular on the 4 lateral walls of relief valve, install the third sealing washer in the annular, the third sealing washer with the inner wall of first cavity forms sealedly, 4 tip of relief valve are equipped with through-hole 43, be equipped with movable sealing element in the relief valve 4, movable sealing element includes second case 41, second reset spring 42 and second sealing washer, second reset spring 42 restriction second case 41 is close to the valve gap, the second sealing washer is installed in the recess of check valve 31 inner wall, second case 41 lateral wall with the second sealing washer contacts and forms sealedly, 4 lateral walls of relief valve are equipped with the apopore, the apopore is in between first sealing washer 32 and the overflow valve 5.

In this embodiment, one end of the overflow valve 5 close to the pressure release valve 4 is provided with a valve sleeve 53, the middle of the valve sleeve 53 is provided with a through hole, a first valve core 51 and a first return spring 52 are arranged in the overflow valve 5, the end of the first valve core 51 is provided with a sealing end, the sealing end comprises a table top 511 and a convex column 512, the convex column 512 is arranged on the surface of the table top 511, a conical inclined surface is arranged at the joint of the table top 511 and the convex column 512, the conical inclined surface and the valve sleeve 53 are in contact to form sealing, an overflow hole is arranged on the overflow valve 5, the overflow hole is communicated with a water inlet for supplying water to the pump body 1, the end of the pump body 1 is connected with a switch box 6, a switch component 61 is arranged in the switch box 6, the switch component 61 is provided with a button 62, the button 62 and the first valve core 51 are arranged on the same straight line, and the first valve core 51 controls the start and stop of the switch component 61.

As shown in fig. 1, in this embodiment, when the high pressure gun is operated, high pressure water enters the water inlet chamber 21 in the second chamber from the water inlet, and then enters the water outlet pipe 3 and the first chamber along the first water path 211 and the second water path 212, respectively, at this time, due to the acting force of the first return spring 52, the tapered slope at the top end of the first valve core 51 contacts with the perforation of the valve sleeve 53 to form a seal, so that water cannot enter the overflow valve 5 through the perforation, and the water passing through the first water path 211 pushes the check valve 31 to flow out from the water outlet pipe 3.

When the high pressure gun is shut down, the pressure in the pump body 1 rises sharply due to the closing of the water outlet pipe 3, the check valve 31 contacts the first water path 211 under the action of the spring, the first water path 211 is sealed under the action of the first sealing ring 32, the force provided by the first return spring 52 in the overflow valve 5 cannot support the first valve core 51 due to the rising of the water pressure in the first chamber, the first valve core 51 is pushed backwards under the action of the water pressure, water flows into the overflow valve 5 from the through hole of the valve sleeve 53 and finally flows out through the overflow hole and is collected into the water inlet, and in addition, the button 62 of the switch assembly 61 and the first valve core 51 are in the same straight line, so when the first valve core 51 moves backwards, the first valve core 51 presses the button 62 of the switch assembly 61, the whole circuit is closed, the switch assembly 61 is closed, the automatic shutdown function is achieved, and energy consumption can be saved.

Because the water on the left side of the pressure release valve 4 enters the overflow valve 5 through the through hole, the water pressure on the left side of the pressure release valve 4 is reduced, after the high-pressure gun is closed, the high-pressure water at the water outlet pipe 3 enters the right side of the pressure release valve 4 through the third water channel 33, because the water pressure on the right side of the pressure release valve 4 is greater than the water pressure on the left side of the pressure release valve 4, the second reset spring 42 in the pressure release valve 4 cannot support the second valve spool 41, the second valve spool 41 is pushed leftwards, when the side wall of the second valve spool 41 is separated from the second sealing ring, the sealing of the pressure release valve 4 is released, the water on the right side of the pressure release valve 4 enters the inside of the pressure release valve 4 through the through hole 43, flows out from the water outlet hole, merges with the water on the left side of the pressure release valve 4, and reduces the water pressure on the right side of the pressure release valve 4.

This embodiment can reduce the water pressure in the pump body 1, makes the water pressure of the pump body 1 inside be less than the water pressure of its during operation far away, reduces the burden that the high-pressure water produced to the pump body 1, can lengthen by a wide margin the life of the pump body 1 reduces the material requirement to the high-pressure rifle, also can avoid simultaneously the high-pressure rifle explodes because of the high-pressure water and splits, reduces the use risk, improves user's safety in utilization, and this embodiment also can make in addition there is certain water pressure difference in the check valve 31 left and right sides, makes the utility model discloses a sealed more reliable, the pressurize is more stable.

When the gun is opened again, the high-pressure water pushes the check valve 31 forward, the first valve core 51 moves rightwards under the action of the first return spring 52, after the conical inclined surface is contacted with the through hole, the first valve core 51 and the valve sleeve 53 maintain sealing again, and meanwhile, the first valve core 51 releases the pressing of the button 62 of the switch assembly 61, so that the switch assembly 61 can be automatically opened, and the maximum pressure and the holding pressure can be adjusted by adjusting the spring force of the first return spring 52 and the second return spring 42.
