With the development of science and technology, fast, safe, convenient and full use of energy have increasingly become the main features of kettles. The working principle of electric kettles is that the water vapor generated when water boils causes the steam temperature sensing element to The bimetallic piece deforms, and this deformation pushes the power switch to cut off the power through the lever principle. It is not self-resetting when the power is cut off, so the kettle will not automatically reheat after the power is cut off. By the 21st century it had become a global bestseller. The electric kettle uses steam intelligent induction temperature control, which has the function of automatically cutting off the power after the water boils and preventing dry boiling. With the needs of life, current electric kettles are also developing towards multi-functions, such as leak-proof, anti-scalding, water locking, etc. Electric kettles have the advantages of fast heating speed, good heat preservation effect, strong filtering function, and many styles. Facing an industry market with such great development potential, establishing a brand and facing the market starts with brand and trademark registration.
