[0023] Please refer to Figures 1-5 , the present invention provides a technical solution for a water-vapor mixing water-saving device: the water-vapor mixing water-saving device includes a flow-limiting component 1, a diversion pipe 2, a sealing ring 3, an air hole 1 - 4, an outer shell 5, a connecting head 6, an air hole 2 - 7, and an external thread 8. The flow-limiting component 1 is embedded inside the diversion pipe 2. Sealing rings 3 are provided on both the upper and lower sides of the outer wall of the diversion pipe 2. An air hole 1 - 4 is opened in the middle of the outer wall of the diversion pipe 2. The outer shell 5 is sleeved outside the diversion pipe 2. A connecting head 6 is provided at the top of the outer wall of the outer shell 5. An air hole 2 - 7 is opened in the middle of the outer shell 5. An external thread 8 is provided at the bottom of the outer wall of the outer shell 5. A mesh plate 9 is installed at the inner bottom end of the diversion pipe 2 to increase the mixing effect of water flow and air;

[0024] The flow limiting assembly 1 includes a fixed head 11, a water inlet hole 12, a flow limiting ring 13, a partition 14, a through hole 15, a conical plate 16, a guide rod 17 and a water-gas mixing shell 18. The water inlet hole 12 is arranged in the middle of the top of the fixed head 11, the middle of the bottom end of the fixed head 11 is connected to the flow limiting ring 13, and the top of the flow limiting ring 13 is connected to the water inlet hole 12. The inner middle of the flow limiting ring 13 is provided with a partition 14, and the through hole 15 is opened at the edge of the partition 14. The middle of the bottom end of the partition 14 is fixedly connected to the conical plate 16, and the middle of the bottom end of the conical plate 16 is fixedly connected to the guide rod 17. The bottom edge of the fixed head 11 is connected to the water-gas mixing shell 18, and the fixed head 11 and the water-gas mixing shell 18 are connected. 8 are embedded into the inner top of the guide pipe 2, an annular hole 19 is opened in the middle of the outer wall of the water-gas mixing shell 18, and an outlet pipe 110 is arranged in the middle of the bottom end of the water-gas mixing shell 18. The bottom of the guide rod 17 extends into the outlet pipe 110, and the guide rod 17 and the center of the outlet pipe 110 are arranged in the same vertical line, so that the guide pipe 17 introduces the water flow into the outlet pipe 110. The outer diameter of the conical plate 16 gradually decreases from bottom to top, so that the water flow is dispersed when passing through the conical plate 16. After the water flow is dispersed, it is drained through the guide rod 17, and the dispersed water flow is mixed with the air. The annular hole 19 is arranged at the same height as the air hole 4, so that the external air enters the annular hole 19 through the air hole 4.

[0025] When in use, the flow limiting assembly 1 is installed in the flow guiding pipe 2, and the flow guiding pipe 2 is installed in the shell 5, a connector 6 is provided on the top of the shell 5, and an external thread is provided on the bottom of the outer wall of the shell 5, and the delay valve and the water inlet pipe of the squat toilet are connected respectively through the connector 6 and the external thread, so that the water-gas mixing water-saving device is installed in the middle of the pipeline;

The water flows downward through the through hole 15 at the edge of the partition 14, and forms a conical water flow after passing through the conical plate 16. The water flow is guided by the guide rod 17. After the water flow forms a cone shape, a gap is formed between the water flow and the top of the outer wall of the guide rod 17, which can effectively mix with the air. Negative pressure is generated at the top of the water-gas mixing shell 18, and external air enters the water-gas mixing shell 18 through the pores and mixes with the water flow. The conical water flow is dispersed, which effectively increases the water-gas mixing effect, thereby increasing the foaming effect, and the foamed water is discharged through the water outlet pipe 110, and is flushed again through the mesh plate 9 to further increase the foaming effect, so that the air and water are fully integrated at the moment the water passes through the water-gas mixing water-saving device. The water volume appears to be the same as usual to the naked eye, but it is actually small bubbles of water. When the water is still, the small bubbles burst, and the water consumption is significantly reduced.
