Technical Field
The invention relates to the technical field of electric heating equipment, in particular to a safety type electric heating faucet structure.
Background
A faucet is a valve that controls the flow and closing of water. The common faucet does not have a heating function, and in cold winter, water flowing out of the faucet of the tap water pipe is very cold, so that cold water for washing dishes and vegetables can cause discomfort to hands and even can cause frostbite; therefore, water heaters are installed in a plurality of kitchens and are matched with a bidirectional faucet to realize the switching use of cold water and hot water.
However, the water heater is limited by conditions (such as installation environment and space limitation) in many times, the water heater cannot be installed in many times, and an electric heating water faucet is arranged on the market at present and is directly installed at a water outlet of a pipeline or connected to the existing water faucet, and an electric heating pipe is adopted inside the electric heating water faucet to rapidly heat water. However, the electric heating faucet has a limited space and belongs to instant heating, so that the use instruction of the existing electric heating faucet usually states that water is firstly introduced and then a heating switch is turned on when the electric heating faucet is used; when the heating switch is closed, the heating switch is closed first, and then the water is closed, so that the damage to the electric heating faucet caused by dry burning of the point heating assembly is prevented. However, a user sometimes can not operate the heating switch accurately according to the requirements in the use specification, for example, sometimes the heating switch is turned on first when water is not supplied, sometimes the water tap forgets to turn off (at this time, the point heating component is in a heating state), and the tap water is cut off, in this case, the point heating component is dried, on one hand, the electric heating water tap is easily damaged, on the other hand, a fire disaster is easily caused, and a great safety hazard exists.
