Dual pressure relief buffer structure and flame-proof and intrinsic safety type power box

The invention discloses a dual pressure relief buffer structure and an explosion-proof and intrinsic safety type power box, and relates to the field of explosion-proof electrical engineering, the dual pressure relief buffer structure specifically comprises a base, an explosion-proof net, a multi-layer explosion-proof plate and a top laminated plate; the explosion-proof net and the multiple layers of explosion-proof plates are sequentially arranged between the base and the top layer pressing plate. The explosion-proof net and the multiple layers of explosion-proof plates are sequentially arranged between the base and the top layer pressing plate, explosion gas passes through the explosion-proof net under pushing of pressure, the explosion-proof net blocks flames and releases a part of heat energy, and therefore the pressure relief effect is achieved; the airflow passes through the narrow explosion-proof cavity formed by the multiple layers of explosion-proof plates, and then the pressure is released again thro
