The limiting block 14 is provided with a plurality of through holes 28 which are uniformly distributed.

The utility model discloses a use method as follows:

when the water faucet is used, a user directly opens a water faucet valve through the handle 2, after the water faucet valve is opened, water flow in a water pipe can enter the water faucet body 1 and then enters the water faucet neck 3, firstly, the water flow enters the right cavity of the water faucet neck 3 and continuously enters the right cavity 10 along with the water flow, the subsequent water flow can form enough water pressure to push the sealing plate 8 leftwards, due to the fact that the movable distance is formed between the sealing plate 8 and the ejector rod 12, if the sealing plate 8 moves to the position of the ejector rod 12, the left movement needs to be performed for a certain stroke, in the left movement process of the sealing plate 8, gas in the left cavity 9 can be extruded by the sealing plate 8, the left cavity 9 is communicated with the outside only through the water faucet mouth 4, the upper end mouth of the water faucet mouth 4 is provided with a plurality of gas blocking holes 18, the existence of the gas blocking holes 18 can effectively slow down the flow rate of the gas in the left cavity 9 when the gas flows to the water faucet mouth, a part of the gas in the left chamber 9 is extruded into the connecting hole 15, the gas entering the connecting hole 15 enters the annular pipeline 23 through the plurality of collecting pipes 22 which are uniformly distributed in the circumferential direction, the gas gathered in the annular pipeline 23 enters the annular rubber bag 16 through the gas supply pipe 24, and the annular rubber bag 16 is inflated and generates elasticity.

After the sealing plate 8 moves to a certain stroke left, the ejector rod 12 penetrates into the corresponding limber hole 11, along with the fact that the ejector rod 12 continues to extend into the limber hole 11, the ejector rod 12 finally touches the one-way plate 20 and pushes the one-way plate 20, the one-way plate 20 tilts towards the upper right by taking a self hinge point as a center, at the moment, the one-way plate 20 does not block and seal the limber hole 11 any more, the left chamber 9 and the right chamber 10 can be communicated through the limber hole 11, along with the fact that the sealing plate 8 moves to the left, the sealing plate 8 can be attached to the limiting block 14, at the moment, the sealing plate 80 blocks and seals the orifice of the connecting hole through the peripheral surface, gas extruded into the annular rubber bag 16 cannot flow back into the left chamber 9 again from the connecting hole 15, and the annular rubber bag 16 keeps in an.

When the water pressure of the water flow is too high, the high-pressure water flow is firstly buffered by the elastic force applied to the sealing plate when the spring 13 contracts, so that the water pressure of the water flow is reduced, when the high-pressure water flow enters the left chamber 9 through the water through hole 11, the water flow needs to pass through the rubber membrane 17 and the annular rubber bag 16 if the water flow is about to flow out from the faucet mouth 4, when the water flow passes through the rubber membrane 17, the high-pressure water flow enters the faucet mouth 4 through the air blocking hole 18, the rubber membrane 17 is pressed downwards by the self pressure, the rubber membrane 17 generates elasticity along with the self pressure, the high-pressure water flow is buffered for the second time, when the water flow passes through the rubber membrane 17, the water flow passes through the annular rubber bag 16, the diameter of the faucet mouth 4 is reduced due to the expansion of the annular rubber bag 16, so that the water flow can inevitably press the annular rubber bag 16, when the annular rubber bag 16 is pressed, the elasticity of the annular rubber bag 16 and the air pressure, the water flow after multi-channel buffering can be sprayed out from the faucet mouth 4 for people to use.

To sum up, can know, the utility model discloses the part of accessible self forms the multichannel buffering, when water pressure is too high, can carry out a lot of buffering to water pressure, makes finally keep at normal water pressure from leading 4 spun rivers of tap mouth, effectively avoids high-pressure rivers to lead to the condition that rivers spatter in disorder to leading 4 inner walls of tap mouth and mouth striking, effectively avoids the user of service to be drenched the condition of clothing by water in the cleaning process, more can avoid rivers to spatter in disorder to the condition that ground leads to the user of service to slip, stops the potential safety hazard.

The inner wall of the slide hole 5 is provided with a plurality of first annular seal grooves 25 which are transversely and uniformly distributed, the outer peripheral surface of the seal plate 8 is provided with a second annular seal groove 26, the first annular seal groove 25 and the second annular seal groove 26 are both internally provided with seal rings 27, and the seal rings 27 in the first annular seal groove 25 can effectively improve the sealing performance between the slide hole 5 and the slide rod 6, so that the water and gas leakage is avoided.

The limiting block 14 is provided with a plurality of through holes 28 which are uniformly distributed, and the existence of the through holes 28 avoids the situation that the limiting block 14 blocks the left end orifice of the limber hole 11 to cause small water flow.
