Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a sealed explosion-proof structure of a carbon battery. Background Art

[0002] Carbon battery is the full name of neutral zinc manganese dioxide dry battery. It is a primary battery among chemical power sources and a disposable battery. It is the most common dry battery at present. It has the characteristics of low price and safe and reliable use. Based on environmental considerations, it still contains cadmium and must be recycled to avoid damage to the earth's environment.

[0003] However, in the existing equipment, the batteries that do not have explosion-proof function have their top covers connected to the top of the zinc cylinder through a sealant. When the carbon battery is in use, the internal volume is easy to expand and the top cover will be pushed out, causing the battery to explode, and the safety index is low. Therefore, a sealed explosion-proof structure for a carbon battery is proposed. Utility Model Content
