Problems solved by technology
[0002] With the development of science and technology and the improvement of people's living standards, the application of electric pressure cookers using commercial power has become common, but after understanding, there is no electric pressure cooker using 24-28V\DC power supply as heating power in the market. It is inconvenient to use electric cooking utensils in places without alternating current (mains power 220V\AC power supply), so electric pressure cookers can only be used in places with alternating current, and the scope of use is relatively limited, and it cannot be used in many places without alternating current The electric pressure cooker is inconvenient to use, and the electric pressure cooker using mains power consumes a lot of energy, and the energy-saving effect is poor
