When water is boiled, a large amount of steam will be generated, and these high-pressure steam will pass through the reed in the pot cover and rush out from the gap around the pot cover, so that the reed will generate vibration and sound when passing through the reed. Because reeds are fixed, no matter how much water is in the pot, the tone of the whistle is the same after boiling. In addition, in order to keep the steam away from the reed gap as much as possible, there is also a cover at the spout to cover the spout when boiling water.

Precautions:
1. The rated power of electric kettle is relatively high. The capacity of power plug, socket and power cord should be selected appropriately, and the specification of 10A should be selected. If the rated power exceeds 2200W, it is necessary to use sockets with larger specifications, and these sockets should be used independently. Therefore, the wire of the electric kettle is relatively short to ensure safety.
2. The plug of the electric kettle generally has a grounding electrode, and the socket with a grounding socket should be connected. When in use, it should be connected to a circuit with safety protection.
3. Always keep the power plug, socket, power cord and automatic switch device of the electric kettle dry and clean.
4, water injection should not exceed the highest water level line, so as to avoid liquid boiling overflow outside the pot. The water injection amount should not be too small to avoid dryness.
5. 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.
