Abstract

The invention discloses an explosion-proof valve. The explosion-proof valve comprises a valve body, an air-permeable film and a protecting sheet; an accommodating cavity is formed in the valve body, an explosion-proof pointed cone is arranged in the accommodating cavity and comprises two or more edge sheets, and all the edge sheets are connected to form the explosion-proof pointed cone in a multi-edge shape, wherein a top cone is arranged at the top of the explosion-proof pointed cone; and the valve body is provided with an exhaust hole, the air-permeable film and the protecting sheet, and theair-permeable film is arranged between the protecting sheet and the explosion-proof pointed cone. A battery exchanges gas with the exterior through the explosion-proof valve mounted on a battery shell, when the pressure of the battery is excessively large and reach the critical value, explosion-proof film paper is pressed towards the accommodating cavity and punctured by the explosion-proof pointed cone arranged in the accommodating cavity, a multi-edge structure on the explosion-proof pointed cone tears the air-permeable film in multiple directions in the direction of the edge sheets, thusa gas flow is divided along edge grooves formed between the edge sheets, the divided gas flow is quickly exhausted out of the explosion-proof valve through the exhaust hole, the battery shell communicates with the outside through the explosion-proof valve, and thus the explosion-proof function is achieved.

Description

technical field [0001] The invention relates to an explosion-proof valve. Background technique [0002] When the new energy battery is in use, it will generate a lot of heat, causing the air pressure to rise sharply. In severe cases, it will cause an explosion. In order to prevent the explosion of the new energy battery, an explosion-proof valve is usually used to match it. Airtight, unbalanced air pressure, and poor explosion-proof effect. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an explosion-proof valve. [0004] Scheme of the present invention is realized like this: [0005] An explosion-proof valve, comprising a valve body, a gas-permeable film and a protective sheet, the valve body has a housing chamber, and an explosion-proof cone is arranged in the housing chamber, and the explosion-proof cone includes at least two prisms, each The prisms are connected to form a polygonal ...
