Second, the working principle of electric kettle is:
The bimetal of the steam temperature sensing element is deformed by the steam generated when the water boils, and the power switch is pushed by the deformed lever principle, so that the electric kettle is automatically cut off after the water boils. Its power failure can't be automatically reset, so the kettle won't be automatically reheated after power failure.
Three. Matters needing attention in the use of electric kettle
1. When in use, the power plug should be completely inserted into the socket. Keep the power plug, socket, power cord and automatic switch device of the electric kettle dry and clean.
2. Water injection should not exceed the highest water level line to avoid overflow when the liquid is boiling. The water injection should not be too little, otherwise the electric heating tube will easily emerge from the water surface, resulting in empty burning. Don't turn on the power supply before adding water, otherwise it is easy to burn out the heater or cause dangerous accidents.
3. When using the electric kettle, be careful not to let children touch the kettle body or the power cord, so as not to cause burns and other accidents.
4. The electric kettle that has just been boiled and connected to the power supply is easy to cause injury when flushing or making drinks. To avoid scalding by boiling water, please unplug the plug first, cut off the power supply, and then use boiling water to ensure safety.
