Power failure memory protection device: When the power is cut off or the power cord is unplugged and a new power is called, or the power supply is connected, the setting function before the power failure can be automatically continued. Temperature limiting safety device: automatically cut off the power when the temperature in the pot reaches the limit. Anti blocking safety device: prevent food from blocking the exhaust valve, and ensure that the exhaust valve is smooth. Safety device for opening and closing the lid: when the lid and the pot body are not buckled properly, the pressure in the pot cannot rise. When the air pressure in the pot is higher than the safety value, the lid cannot be opened. Overtemperature safety device: when the pot is empty or the temperature in the pot exceeds the set safety value, the power supply will be cut off automatically.

Pressure control safety device: it can automatically cut off power in case of exceeding the set pressure during use. Pressure relief safety device: when the pressure in the boiler exceeds the safety value due to the failure of the pressure limiting safety device, the pressure relief mechanism will work to automatically exhaust and relieve the pressure around the boiler to ensure that no accident of boiler explosion will occur. Pressure limiting safety device: when the pressure in the boiler increases to the upper limit, the pressure limiting vent valve will automatically exhaust and limit the pressure.
