The water outlet valve core seat is provided with a valve core connecting thread, and is connected to the water outlet valve core through the thread. The water outlet valve core is provided with a water outlet end. The valve stem of the water outlet valve core is provided with a handwheel connecting thread, and is connected to the water outlet control handwheel through the thread. The water outlet control handwheel is provided with a water outlet nozzle connected to the water outlet end.
[0007] Furthermore, the water outlet end of the valve core is arranged on the valve stem of the water outlet valve core.
[0008] Furthermore, the water outlet control hand wheel is provided with an anti-skid concave-convex structure.
[0009] Furthermore, the hot and cold regulating valve core adopts a constant temperature valve core.
[0010] Furthermore, a one-way valve is provided between the cold water pipe and the cold water inlet, and between the hot water pipe and the hot water inlet to prevent cross-flow of cold and hot water.
[0011] Compared with the existing technology, the utility model has the following advantages: it solves the inconvenience and safety hazards caused by the integrated design of hot and cold water adjustment and water outlet switch. By using a thermostatic valve core to control the hot and cold water outlet, the water outlet switch is directly designed at the outlet of the water pipe, which is more convenient to use. After adjusting the water temperature once, there is no need to adjust it again the next time. At the same time, it can greatly reduce the probability of burns for the elderly and children.
