Today's electric kettle is equipped with temperature control technology, which can freely select the appropriate heating temperature according to the needs. In order to realize the accurate temperature control of the electric kettle, it is usually necessary to be equipped with a temperature sensor to detect the water temperature in the kettle in real time. Most of the water on the market, the temperature sensor is usually installed at the bottom of the kettle, such as the patent document with the announcement number CN211673765U provides an IH temperature control kettle with dry burning prevention structure at the bottom of the kettle. However, the kettle bottom is usually equipped with a heating disc and other heating units, and the temperature sensor will be affected by the heat of the heating unit, resulting in inaccurate temperature measurement data of the water.
