EXPLOSION-PROOF VALVE

WIPO Patent Application WO/2023/098596

A1

An explosion-proof valve comprises a valve body (100), a moisture absorption member (200), and a valve core assembly (300). An accommodating cavity (110) is formed in the valve body (100), a first end face (121) of the valve body (100) is provided with a first opening (122), a second end face (131) of the valve body (100) is provided with a second opening (132), and the first opening (122), the accommodating cavity (110) and the second opening (132) are sequentially communicated. The moisture absorption member (200) is arranged in the accommodating cavity (110). The valve core assembly (300) is connected to the valve body (100). The valve core assembly (300) slides between a first position and a second position with respect to the valve body (100). When at the first position, the valve core assembly (300) covers the first opening (122), and when at the second position, the valve core assembly (300) moves away from the first opening (122). The explosion-proof valve can prevent moisture from damaging the interior of a battery pack device, and facilitates the replacement of the moisture absorption member.
