Pressure relief structure and its manufacturing process, and explosion-proof method

A pressure relief structure, comprising:

• a container body (1), at least comprising:
• a shell (11), and a cover (12);
• wherein at least one weak area forming embedding strip (3) is embedded in at least one of the cover (12) and at least one part of the shell (11) to thereby allow the at least one of the cover (12) and the at least one part of the shell (11) to have a pressure relief weak area (15);
• a thickness of the cover (12) is greater than an embedding depth of the at least one weak area forming embedding strip (3) embedded in the cover (12), and/or a thickness of the at least one part of the shell (11) is greater than an embedding depth of the at least one weak area forming embedding strip (3) embedded in the at least one part of the shell (11);
• and the pressure relief weak area (15) and the at least one weak area forming embedding strip (3) are configured to open along a length direction of the at least one weak area forming embedding strip (3) when in a pressure relief state.
