Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric kettle, in particular to a graphene electric kettle. BACKGROUND

[0002] Water kettle is a device for quickly boiling water for making tea, cooking, etc. The working principle of electric kettle is that the steam generated when water boils deforms the bimetallic strip of the steam temperature sensing element, and this deformation pushes the power switch off through the principle of lever, or a temperature monitoring probe is used to continue monitoring the water temperature, and when the water temperature reaches 100 DEG C, the air power is turned off by the controller.

[0031] Exemplary embodiments of the present disclosure will be described in greater detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be accurately conveyed to those skilled in the art.
