[0002] A steam generator, also known as a steam boiler, is a device specifically used to convert water into steam and is widely used in various fields such as industrial production, power generation, heating, cooking, etc.

[0003] The steam generator heats water by burning fuels (such as coal, natural gas, petroleum, etc.) or using other energy sources (such as nuclear energy, solar energy, electric energy, etc.) to generate heat, turning it into steam. Among them, the common heating method is electric heating. Existing electric heating steam generators usually only use a single ordinary float level gauge to detect the liquid level height in the generator, with poor accuracy. And when the float of the level gauge gets stuck or damaged, it cannot normally detect the liquid level height, easily resulting in situations such as overcharging or emptying.

[0004] In view of this, research and improvement are carried out on the existing problems, and an electric heating steam generator is provided, aiming to solve the problems and improve the practical value through this technology. Summary of the Utility Model
