Description

Technical Field

[0001] This utility model relates to a faucet. Background Technology

[0002] As an essential water-using device in daily life, the structure and function of a faucet directly affect the user experience and convenience. The basic structure of a traditional faucet typically consists of two main parts: the faucet body and the valve assembly. The faucet body is usually mounted on the countertop, providing a stable water outlet for the user, while the valve assembly is located inside or near the faucet body, responsible for controlling the water flow, flow rate, and temperature. Currently, the most common faucet valve assembly on the market adopts a "two-in, two-out" design, meaning it has two inlets and two outlets. The two inlets connect to the cold water pipe and the hot water pipe, respectively, to introduce hot and cold water; the two outlets are used to deliver mixed water and for other diversion purposes. One outlet connects directly to the faucet's spout for regular water dispensing; the other outlet is usually connected to a solenoid valve, from which a water pipe is led out and finally connected to the faucet's spout.

[0003] However, while this dual-inlet and dual-outlet valve assembly design improves the functionality of the faucet to some extent, it also brings some problems. First, the need to introduce multiple inlet and outlet water pipes and the circuitry to control the solenoid valve makes the internal wiring and piping more complex, which can easily lead to difficulties in installation and maintenance.
