STORAGE BATTERY WITH AIR CHAMBER EXHAUST SYSTEM

摘要

A storage battery with an air chamber exhaust system belongs to the technical field of a maintenance-free double cover-type lead-acid battery, and is used to solve the problems that the air exhaust is not sufficiently unobstructed and the effect of acid resistance is not sufficiently good in the exhaust system of the existing storage battery. The storage battery comprises polar plates, a casing, and an acid backflow resistance labyrinth structure of the battery, wherein the casing is composed of a casing body, an exhaust cover and a big cover; the labyrinth structure is formed by a space between the big cover and the exhaust cover; a part where an end of the labyrinth structure is in communication with the outside of the storage battery is the exhaust system; an air passageway is formed by a separation wall which is used for separating the exhaust system from other parts; a first air filter and a second air filter which are distributed in series along the airflow direction are arranged in the air passageway; and an air chamber is formed by the big cover and a barricade of the exhaust cover behind the first air filter. The storage battery is characterized by unobstructed air exhaust and good acid resistance effect, and is mainly used for filtering the exhausted air of the maintenance-free lead-acid battery.
