Background technique

Traditional household water heaters mostly use resistance water heaters or natural gas water heaters. Before using resistance water heaters, it takes a lot of time to preheat the water in the water tank. After the hot water is used up, you need to wait for the water heater to heat the water again. Moreover, the embarrassment of running out of hot water and cutting off the hot water supply will occur during use; although natural gas water heaters are convenient, they cannot be popularized in all urban households due to the limitation of natural gas resources. Although a large amount of electromagnetic water heaters have come out in recent years, brought convenience to people's life. However, most electromagnetic water heaters use a built-in electromagnetic induction structure. The electromagnetic coil is set in the inner tank of the water tank. During the frequent heating of the electromagnetic coil, the enameled wire will age, causing a short circuit between turns, or a short circuit with the inner tank, causing accidents. For this reason, need a kind of like natural gas water heater, the water heater device that can use instantly, satisfy people's use demand.
