Will the electric pressure cooker explode?

The electric pressure cooker will not explode when used normally according to the instructions. However, if you don't use it according to the instructions, for example, cover it casually, don't cover it, just put it a little, which will lead to no air leakage when the pressure in the pot is small, and the pressure in the pot will gradually increase. When the pressure is high, the cover will suddenly open and explode. If the food cooked in the pot blocks the safety valve, at least the double temperature limiting device of the pressure cooker just fails, and the power supply is not cut off in time, which will lead to excessive pressure in the pot and explosion (this may need to happen at the same time, which is extremely unlikely).
