Thermostatic valve element of faucet

The invention discloses a thermostatic valve element of a faucet. The thermostatic valve element of the faucet comprises a valve element body, a valve rod, a support, a lifting rod, a temperature sensing rod, a sealing piece, a spring, a movable valve block, a fixed valve block, an inner rubber ring, a base and an outer rubber ring, wherein the valve rod and the support are arranged in the valve element body in sequence from top to bottom. The lifting rod, the temperature sensing rod, the sealing piece, the spring, the movable valve block, the fixed valve block, the inner rubber ring and the base are arranged in the middle of the valve rod, and the outer rubber ring is arranged on the base. The temperature sensing rod stretches or retracts to control the inlet flow of cold and hot water through the spring and the sealing piece, and therefore the temperature of discharged water always reach a set value. A water outlet is formed in the lower end of the base. Compared with an existing constant temperature valve element, when the thermostatic valve element is installed, the inner structure of a faucet body is simpler, implementation is convenient, and limitation of the center distance of a water inlet is avoided; meanwhile, the material consumption of the faucet body is reduced, and production cost is lowered.
