Abstract

The utility model discloses a battery box, a battery and an electric device. The battery box comprises a box body, a pressure relief mechanism and a flow guide cover, and the pressure relief mechanism is arranged on the box body; the flow guide cover is connected with the outer side of the box body in a clamped mode, the pressure relief mechanism is covered with the flow guide cover and used for guiding gas sprayed out of the pressure relief mechanism to the outside of the box body, and the flow guide cover is provided with a flow guide opening used for exhausting the gas. As the flow guide cover is clamped with the outer side of the box body, bolt locking is not needed, the problem of torque attenuation of bolt locking is avoided, and the connection sealing performance between the box body and the flow guide cover is enhanced, so that the reliability of the battery is improved.
