The common tap does not have a heating function, and in cold winter, water flowing out of the tap water pipe is cold, so that the tap is uncomfortable to the hands and even frostbite can be caused by washing dishes and vegetables with cold water; therefore, water heaters can be installed in a plurality of kitchens, and the switching of cold water and hot water can be realized by matching with the bidirectional faucet.
However, many times limited by conditions (such as installation environment and space limitation), many times incapable of installing a water heater, an electric heating faucet is currently available on the market, and is directly installed at a water outlet of a pipeline or connected to an existing faucet, and an electric heating tube is adopted to rapidly heat water. However, because the internal space of the electric heating faucet is limited, the electric heating faucet belongs to instant heating, the use instruction of the existing electric heating faucet is usually written with "water is firstly supplied when in use, and then a heating switch is turned on; when the electric heating faucet is closed, the heating switch is firstly closed, and then water is turned off, so that the electric heating faucet is prevented from being damaged due to dry heating of the spot heating assembly. However, the user can sometimes not operate the heating switch according to the requirement in the instruction, for example, when the water is not supplied, the heating switch is turned on first, and when the tap is forgotten to be turned off (when the spot heating assembly is in a heating state), the tap water is cut off, so that the problem of dry heating of the spot heating assembly can be caused, the electric heating tap is easy to damage, and on the other hand, fire is easy to occur, and great potential safety hazards exist.
