Pressure cooker, also called pressure cooker, pressure cooker, is a kind of kitchen cooker. The pressure cooker exerts pressure on water through the physical phenomenon that the boiling point of liquid will rise under higher air pressure, so that the water can reach a higher temperature without boiling, thus accelerating the efficiency of stewing food. It can be used to heat cooked food to above 100℃. At high altitude, the pressure cooker can avoid the problem that the boiling point of water decreases and it is difficult to cook food.

1. If there is air leakage at the pressure cooker handle, it may be that the float sealing ring is broken. Replace the floating sealing ring in time to solve the air leakage problem of the pressure cooker handle.

2. If there is food residue on the sealing ring of the float, it will also lead to air leakage at the handle of the pressure cooker, so the sealing ring can be cleaned and the problem of air leakage at the handle of the pressure cooker can be solved.

3. If you accidentally break the lid of the pressure cooker, it may lead to air leakage at the handle of the pressure cooker. A pot cover can be replaced in time to solve the problem of air leakage in the pressure cooker.

4. If the lid is not properly covered, there may be air leakage at the handle of the pressure cooker, and the problem of air leakage can be solved by properly covering the lid.

5. If the float of the pressure cooker is resisted by the connecting plate of the push rod when it rises, it will lead to air leakage at the handle of the pressure cooker. At this time, the problem of air leakage at the handle can be solved by pushing the connecting plate of the push rod with a small screwdriver.
