[0002] Faucets are widely used in homes and public places, usually installed on water pipes. The water flow can be opened or closed by manipulating the internal valve core to adjust the strength and temperature of the water flow. The temperature-adjustable faucets on the market include two cold water inlet pipes and hot water inlet pipes for cold water and hot water to flow in respectively. The cold water inlet pipe and the hot water inlet pipe are connected to the faucet body at the same time. The flow of hot water and cold water is adjusted by the valve core inside the faucet body to adjust the temperature of the water flow mixed in the faucet body to a suitable temperature to meet the user's needs, and the material of the faucet is usually copper. The traditional faucet is overall low, which makes the user's use space small and easy to touch the water outlet pipe, making it very difficult to use. In order to facilitate the user's use, the bottom of the faucet in the prior art is usually higher, which increases the height of the faucet and the use of copper materials, thereby making the manufacturing cost of the faucet higher.
