Constant temperature cup principle
The steam generated when the water boils distorts the steam temperature sensing element made of bimetal, and then the power supply is controlled by lever principle, so that the electric kettle automatically turns off the power after the hot water is boiled.
When the reheated water temperature is low to a certain extent, the deformed bimetal will return to its original position, so the water temperature will be heated again, and finally the effect of constant temperature kettle will be realized.
The principle of balance between energy absorption and energy release In physics, there is some solid substance in the cup that can absorb heat, which can instantly absorb a lot of heat, so that the water temperature can be kept at a certain temperature without heat dissipation.
