There is no water in the health pot, and a pressure switch is designed on it. When the pressure pump is sensed, water will be supplied. After turning on the power, make sure there is water in the pot. If there is still unfinished tea after plugging in, put the health pot in the refrigerator, stir it before reheating, plug in electric heat after room temperature, and stir it before boiling to prevent the food at the bottom of the pot from sticking to the bottom and causing harm.
