Exhaust assembly and soft package battery module shell

The utility model discloses an exhaust assembly and a soft package battery module shell. The exhaust assembly comprises a fireproof plate and an exhaust main body which are stacked, penetrating fireproof air holes are formed in the fireproof plate; the exhaust main body is provided with a cavity structure; an air inlet hole is formed in the side, close to the fireproof plate, of the exhaust body and communicates with the cavity structure. An air outlet hole is formed in the side, away from the fireproof plate, of the exhaust body and communicates with the cavity structure. And the orthographic projection of the orifice of the fireproof air hole close to one side of the exhaust main body and the orthographic projection of the orifice of the air inlet close to one side of the fireproof plate on the fireproof plate are completely or partially overlapped. The utility model has the beneficial effects that when the whole exhaust assembly is in thermal runaway of the soft package battery core, the air inlet hole and
