Why did the pressure cooker explode?

The reason why the pressure cooker will explode: When the air outlet valve and safety valve are blocked and the pressure cooker is still heating, the pressure in the cooker will explode if it exceeds the pressure that the pressure cooker can bear.

Suggestion: Be sure to carefully check the outlet valve and safety valve of the pressure cooker before use, and replace the safety plate in the safety valve regularly.
