<p>The present invention relates to an inner canister of an explosion-venting-type aerosol fire suppression apparatus, comprising a canister body (3) and a canister cover component (4) arranged on one end of the canister body (3), also an explosion-venting apparatus arranged on the canister body (3). The explosion-venting apparatus comprises a friction layer (11), a connecting rod (12), a guiding unit (13), and a limiting apparatus (14). The connecting rod (12) and the canister cover component (4) are connected. The friction layer (11) is arranged between the connecting rod (12) and the canister body (3). The friction layer (11) provides a frictional resistance and buffering force for the connecting rod (12) when same is displaced, under the guidance of the guiding unit (13), along a direction that a hot air stream of the canister body (3) is jetting towards. The guiding unit (13) is an apparatus capable of providing guidance for the connecting rod (12) when same is moving. The limiting apparatus (14), the canister cover component (4), and the connecting rod (12) are fixedly connected. The limiting apparatus (14) limits the connecting rod (12) when an extremity thereof slides to the canister cover component (4). The present invention uses primarily the movement and limiting of the explosion-venting apparatus to consume kinetic energy generated by deflagration, thus achieving the goal of safe and effective explosion ventilation, and preventing a grain (7) from causing injuries and damages when deflagrated.</p> |
