Abstract: The present application relates to a battery box, a battery, and an electrical apparatus. The battery box comprises: a box body on which a mounting opening for mounting a pressure relief mechanism is formed; and an auxiliary member provided on an outer surface of the box body, with an exhaust channel in communication with the mounting opening being defined and formed between the box body and the auxiliary member, wherein an exhaust port in communication with the exhaust channel is provided on the auxiliary member.

Abstract: The present application provides a sealing member, a battery, and an electrical apparatus. The sealing member includes a main body and a securing structure disposed on the main body. The securing structure is connected to a positioning structure on a member to be sealed to secure the sealing member on the member to be sealed. A surface of the securing structure facing the member to be sealed is provided with a recess, and the recess is recessed in a direction away from the positioning structure to prevent the sealing member from being fitted reversely. The sealing member provided by the present application can prevent the sealing member from being fitted reversely.

Abstract: The present application provides a battery and an electrical apparatus with good heat dissipation performance. The battery includes: an air-cooling structure including a body and at least one air duct penetrating the body in a first direction; and a plurality of battery cells, wherein the plurality of battery cells are cylindrical, axes of the plurality of battery cells are parallel to the first direction, and the plurality of battery cells are arranged around the air-cooling structure; and the air-cooling structure is configured to discharge heat generated by the plurality of battery cells with air introduced into the air duct.

Abstract: The present application provides a battery and powered equipment with good heat dissipation performance. The battery includes: a plurality of battery cells, the plurality of battery cells being cylinders; and an air-cooling structure, including a body and at least one air duct penetrating the body in a first direction (X), the first direction (X) being parallel to an axial direction of the plurality of battery cells, and a cross section of the air duct perpendicular to the first direction (X) being in a fin shape.
