The upper and lower valve core mounting seats respectively house a thermostatic valve core for constant-temperature water output and a quick-opening valve core for switching the water flow on and off. The faucet handle is equipped with a hexagonal nut for fixing the upper valve core mounting seat, and the upper valve core mounting seat is equipped with a valve core that mates with the top of the thermostatic valve core. The connector has a hexagonal countersunk hole at the bottom of the inner wall of the faucet body, and a hexagonal inner hole pressure cap is connected inside the hexagonal countersunk hole. The bottom end of the quick-opening valve core has a hexagonal valve stem that is inserted into the hexagonal inner hole pressure cap. The faucet body has a water inlet channel one and a water inlet channel two. The bottom of the faucet body has a water inlet port one and a water inlet port two that are connected to the water inlet channels one and two, respectively. The lower valve core mounting seat has a plurality of water inlet holes one and a plurality of water inlet holes two that are connected to the water inlet channels one and two. The lower valve core mounting seat also has a plurality of water outlets for constant temperature water.

[0006] In the above-mentioned single-handle thermostatic faucet for washbasins, the faucet body has a molded seat for placing and installing the lower valve core mounting seat, and the molded seat separates the water outlet from the two water inlets.

[0007] In the above-mentioned single-handle thermostatic faucet for washbasins, the faucet body also has a partition that separates the first water inlet channel and the second water inlet channel.

[0008] In the above-mentioned single-handle thermostatic faucet for washbasins, the inner wall of the faucet handle has a toothed ring portion, and the outer wall of the upper valve core mounting seat has a positioning toothed ring that mates with the toothed ring portion.
