[0002] Faucets are the popular name for water valves, which are used to control the size of water flow and have the effect of saving water. The replacement speed of faucets is very fast, from the old cast iron process to the electroplated knob type, and then to the stainless steel single-temperature single-control faucet, stainless steel double-temperature double-control faucet, and kitchen semi-automatic faucet. Now, more and more consumers will consider the material, function, shape and other aspects when purchasing faucets. According to the function, they can be divided into basin, bathtub, shower, kitchen sink faucet and electric hot water faucet, etc. According to the structure, they can be divided into single-type, double-type and triple-type faucets. The single-type can be connected to the cold water pipe or the hot water pipe, and the double-type can be connected to both cold and hot pipes at the same time. It is mostly used for bathroom basins and kitchen sinks with hot water supply. In addition to connecting to the cold and hot water pipes, the triple-type can also be connected to the shower head, and is mainly used for bathtub faucets. Due to the diversification of functional requirements, dual-outlet faucets have become the mainstream of bathroom faucets.
