Extended data:

1, pressure cooker, also known as pressure cooker. The advantage of using a pressure cooker is not only that the cooking time is short, but also that the cooked food tastes good, especially the meat that is not easy to cook becomes easy to cook and tastes good.

The principle of pressure cooker is very simple, because the boiling point of water is affected by air pressure. The higher the air pressure, the higher the boiling point. On mountains and plateaus, the air pressure is lower than 1 atmospheric pressure, and water can boil below 100℃. Eggs are not cooked in ordinary pots and pans. When the air pressure is greater than 1 atmospheric pressure, water will boil only when it is higher than 100℃. The pressure cooker commonly used by people is designed by using this principle.

3. In order to ensure the use safety of the pressure cooker and avoid the failure of the fusible piece due to material changes, even under normal use, the fusible piece in the fusible piece safety valve should be replaced once every six months.
