Description

Top cover exhaust structure of lead-acid storage battery Technical Field The utility model relates to the technical field of top covers of storage batteries, in particular to a top cover exhaust structure of a lead-acid storage battery. Background Currently, lead-acid storage batteries are widely used as energy storage devices, and gases such as hydrogen and oxygen are generated in the charging and discharging processes, and accumulate in the battery and lead to pressure rise. The traditional exhaust structure often has the problems of poor tightness, incapability of effectively preventing external air from entering, lack of effective purification of exhaust gas and the like, and cannot completely meet the high standard requirements of modern application on safety and environmental protection. In addition, when outdoor use, rainwater or other liquid easily gets into inside the battery through the exhaust hole, has further increased the risk of trouble. Therefore, we propose a top cover exhaust structure of a lead-acid storage battery. Disclosure of utility model The utility model mainly aims to provide a top cover exhaust structure of a lead-acid storage battery, which can effectively solve the problems in the background technology.
