Description

Technical Field

[0002] An instant liquid heating device is a device that directly heats a flowing liquid using an electric heating element, allowing it to reach the desired temperature or a specified temperature within a short time. The liquid can include water, oil, etc. Its basic principle is to utilize the resistance heating effect of conductive materials to convert electrical energy into heat energy, thereby rapidly heating the liquid. Specifically, when water flows through the heating element, the current passing through the element generates heat, which is quickly transferred to the liquid, raising its temperature and achieving an instant heating effect. Its core features are instant heating, on-demand supply, and energy efficiency, making it widely used in homes, industry, and commerce.

[0003] In traditional instantaneous liquid and gas heating equipment, the pipe connections and electrical connections are typically located at the ends of the casing. For example, in an energy-saving heater described in patent application number 202120709759.2, the casing, first pipe, second pipe, and multiple heating components are all integrally molded.
