Technical Field

[0001] This utility model relates to a thermostatic faucet, and more particularly to a split-type thermostatic faucet. Background Technology

[0002] A thermostatic faucet is a type of faucet that uses a thermostatic valve core to mix cold and hot water to create a pre-set temperature of warm water. Therefore, thermostatic faucets are typically installed in bathrooms. Since thermostatic faucets are used in conjunction with washbasins, which are typically wall-mounted, the installation location of the thermostatic faucet is extremely close to the wall. If the thermostatic valve core malfunctions and requires repair, the space available for disassembly is limited by the wall, making the disassembly process difficult. Furthermore, the faucet body is a single unit, with the thermostatic valve core directly installed within its cavity. While removing the thermostatic faucet from the plumbing system first allows for quick removal of the valve core, it necessitates reinstalling the faucet body after installing a new valve core, significantly increasing workload and impacting overall disassembly efficiency.
