Pressure cooker, also called pressure cooker, is a kind of kitchen utensil. The boiling point of the liquid in the pressure cooker at a higher pressure will enhance this physical phenomenon, so that the water can reach a higher temperature without boiling, so as to speed up the efficiency of stewing food. It can be used to heat the cooked food to more than 100 ℃. In high altitude areas, the use of pressure cooker can avoid the problem of reducing the boiling point of water and making it difficult to cook food.

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.
