The water inlet pipe 110 is connected to a water supply point, and water flows from the water inlet pipe 110 into the chamber and can be divided into a plurality of water outlet pipes 120, for example, a one-way water dividing valve with two water outlet pipes 120 is provided, and the water flow of one water supply point can be divided into two different water flow branches, but it should be understood that the number of the water outlet pipes 120 should be set in advance according to needs, and the number is not limited to two; a fixing device for clamping the one-way valve device 200 is arranged in each water outlet pipe 120 to prevent the one-way valve device 200 from entering the cavity and prevent the one-way valve device 200 from being separated from the water outlet pipe 120; the control direction of the check valve device 200 to the water flow is from the chamber to the water outlet pipe 120, that is, the water flow can be controlled to only flow out from the water outlet pipe 120, but not to flow back into the chamber from the water outlet pipe 120, so as to prevent the water flow branches from flowing back and streaming with each other.

In some embodiments of the present invention, the fixing device includes a first clamping table 130 and a second clamping table 140, the first clamping table 130 and the second clamping table 140 are disposed on an inner side wall of the water outlet pipe 120, the first clamping table 130 and the second clamping table 140 are spaced apart in an axial direction of the water outlet pipe 120, the first clamping table 130 is located at a side close to the chamber, the second clamping table 140 is located at a side close to an outlet end of the water outlet pipe 120, and the check valve device 200 is clamped between the first clamping table 130 and the second clamping table 140.

The first clamping table 130 prevents the check valve device 200 from entering the cavity, and the second clamping table 140 prevents the check valve device 200 from being separated from the water outlet pipe 120, so that the clamping structure is simple, and the production and the processing are convenient.

In some embodiments of the present invention, the check valve device 200 includes an outer valve housing 210, a valve core 220, a valve seat 230, and a spring 240, the valve seat 230 abuts on the second chuck 140, the valve seat 230 has a coaxial guide sleeve 231 at the center, the outer valve housing 210 abuts on the first chuck 130, so that the outer valve sleeve 210 is tightly attached to the inner wall of the water outlet pipe 120 for sealing, the outer valve sleeve 210 is coaxial with the valve seat 230, and are clamped with each other, one side of the outer valve sleeve 210 far away from the valve seat 230 is provided with a sealing boss 211 inwards towards the axial line, the valve core 220 is provided with a guide post 221 and a sealing block 222 which are coaxially connected, the guide post 221 is inserted in the guide sleeve 231, the sealing block 222 is located between the valve seat 230 and the sealing boss 211, a groove is arranged on the sealing block 222 in a surrounding mode, the first sealing ring 300 is nested in the groove, the spring 240 is sleeved outside the guide sleeve 231 and located between the valve seat 230 and the sealing block 222, and the first sealing ring 300 is tightly pressed on the sealing boss 211.

In this structure, when water flows out from the chamber to the water outlet pipe 120, the water pressure in the chamber is so high that the valve element 220 is pressed to move towards the second clamping platform 140, at this time, the sealing block 222 drives the first sealing ring 300 to leave the sealing boss 211, the spring 240 is also compressed, and the water flows through the gap between the first sealing ring 300 and the sealing boss 211, then flows through the valve seat 230, and then flows out from the water outlet pipe 120.

If the water pressure in the cavity is smaller than the water pressure outside the water outlet pipe 120, that is, the water flow has a tendency of reverse flow, at this time, the water flow enters from the valve seat 230, a pressure towards the first clamping table 130 is applied to the sealing block 222, meanwhile, the compressed spring 240 starts to reset, a thrust towards the first clamping table 130 is also applied to the sealing block 222, and the sealing block 222 drives the first sealing ring 300 to move so as to be tightly pressed on the sealing boss 211, so that the water flow is cut off and sealed, and the reverse flow is avoided.
