1. safety protection: the safety tube plays a safety protection role in the heating plate circuit of the health pot. The heating plate circuit usually generates high temperature. By installing safety tubes, problems such as overheating, overload or short circuit can be effectively prevented, and potential safety hazards such as fire and electrical damage can be avoided.

2, temperature control: the safety tube can also help control the temperature of the heating plate of the health pot. It is usually equipped with a thermal circuit breaker or a thermal protector. When the temperature exceeds the set safety range, the insurance management tube will automatically cut off the power supply to prevent the heating plate from overheating and causing accidents.
