Technical Field

[0001] This utility model relates to the field of faucet technology, and in particular to a combined faucet. Background Technology

[0002] Faucets are very common in our daily lives. Faucets are generally made of one piece of metal. However, metal faucets are expensive to produce and can corrode or leach harmful substances after prolonged use. As a result, a number of modular faucets have emerged on the market, which manufacture the inner core and the shell of the faucet separately. This avoids the corrosion that is prone to occur with all-metal materials. However, in order to facilitate the removal of the inner core, the water outlet pipe on the inner core of the modular faucet is often located at the lower end of the valve core seat, and cannot be set at the upper end of the valve core seat. This makes the faucet style more limited, and it also means that manufacturers have to raise the faucet body to make the spout height reasonable during actual production, which increases production costs.
