The sliding block 12 drives the plug assembly 2 to move upwards. The concave portion 22 of the plug assembly 2 opens the water outlet hole 36 at this time, water flows into the lower water cavity 44 from the water outlet hole 36, and since the flow rate of the water inlet hole 35 is smaller than that of the water outlet hole 36, the volume of the upper water cavity 43 is continuously reduced, the diaphragm assembly 3 is pushed to move upwards, a gap is opened between the sealing gasket 31 and the base 9, and the water outlet 42 is opened.
In a low-flow state, as shown in fig. 6, when the water outlet 42 is opened, the knob 51 is rotated, the knob 51 drives the slider 12 to rotate, the slider 12 drives the plug assembly 2 to rotate, the plug assembly 2 drives the upper adjusting piece 52 to rotate, and when the overlapping surface between the upper adjusting hole 521 and the lower adjusting hole 531 is minimum, the flow is minimum.
In the high flow state, as shown in fig. 7, when the upper regulation hole 521 and the lower regulation hole 531 are completely aligned, the flow rate is minimum when the overlapping surface is maximum.
The water outlet is adjusted through the flow adjusting assembly, and when the membrane assembly opens the water outlet, the flow adjusting assembly is used for adjusting the size of the water outlet. Because the flow regulating assembly is integrated in the switch valve, the whole structure of the product is simple and the use is convenient.
