The health pot will not explode when it is hot and cold alternately. Because the working principle of health pot is to achieve the effect of heat preservation through the circulation of water. When the water temperature rises, the temperature sensor in the incubator will automatically sense the temperature change, and then cut off the power supply and stop heating through the control circuit. When the water temperature drops, the temperature sensor in the incubator will sense the temperature change again, and then turn on the power supply through the control circuit to start heating. To sum up, the health pot will not explode when it is hot and cold alternately.
