The existing faucet is generally provided with at least one temperature regulating valve and a switching valve, wherein the temperature regulating valve is used for controlling the proportion of cold water and hot water so as to control the temperature of mixed warm water, and the switching valve core is used for controlling the water outlet of the warm water. Correspondingly, two mounting holes are needed to be formed in the faucet main body and are respectively used for mounting the temperature regulating valve and the switching valve, and meanwhile, a runner from warm water mixed by the temperature regulating valve to an inlet of the switching valve and a runner from an outlet of the switching valve to a water outlet of the faucet are needed to be arranged in the faucet. The waterway inside the tap is troublesome.
The chinese patent 202010306773.8 discloses a rotary pressure-switch thermostatic valve and faucet assembly which simplifies the faucet internal flow path structure by combining the temperature regulating portion and the switch portion into one cartridge. When the valve is in operation, cold water and hot water flow downwards from the lower end of the valve core, pass through the lower end of the inner peripheral wall of the piston assembly, then enter the inner peripheral wall to flow upwards again, pass through the temperature sensing part of the temperature sensing element, then flow through the outer side of the temperature sensing element and enter the switching mechanism. The water flow flows like this, the flow is longer, the pressure loss is larger through multiple turning, and the water outlet flow is smaller. Meanwhile, the temperature sensing area of the temperature sensing element is close to the cold water inlet and the hot water inlet, after the cold water and the hot water enter the valve core, the cold water and the hot water are not fully mixed and are in contact with the temperature sensing area of the temperature sensing element, the temperature sensing element cannot accurately sense the water temperature after being uniformly mixed, and therefore temperature adjustment is inaccurate. In addition, need set up the twice sealing washer between piston assembly and the lower casing, be in between peripheral wall and the lower casing together, another way is in between inner peripheral wall and the lower valve body, and the twice sealing washer has great resistance when leading to piston assembly to slide, and it is inflexible to slide, can't change cold and hot water mixing ratio in real time, and the fluctuation of water temperature is big in the use. And the sealing ring is arranged in the sealing ring on the inner wall of the lower valve body between the inner peripheral wall and the lower valve body, so that the space is small, and the sealing ring is very inconvenient to install.
