Raw explosion.Therefore in order to which battery is using safe, blast resistance construction would generally be additionally provided in battery.But the sealing ring added and anti-
Quick-fried structure influences whether battery dischargeable capacity, and battery storage electricity is caused to reduce.
Some sealing structure of alkaline manganese cell offer gas vent on its cathode bottom cover, for being connected to inside battery and the external world
Atmosphere, although avoiding battery occurs the possibility integrally exploded, gas vent is also easy to be blocked by dust, and it is quick-fried to increase battery
Fried and leakage risk, therefore such design can also bring very big security risk.
Utility model content
In view of the above-mentioned state of the art, the technical problem to be solved by the utility model is to provide a kind of alkali manganese electricity
Pond sealing ring improves the explosion-proof capabilities of alkaline Mn cell, avoids battery that leakage occurs, battery capacity has been effectively ensured, and improves
The safety of battery.
Technical solution adopted by the utility model to solve the above technical problems is as follows:
A kind of alkaline Mn cell sealing ring, sealing ring include recess portion and interconnecting piece, table in recess portion outer surface and battery case
Face abuts against, and battery case, which is equipped with, hooks folding part, recess portion outer surface and hooks and forms the first cavity between folding part, recess portion inner surface and negative
The contact of pole bottom cover ends, interconnecting piece bottom surface contacts with cathode bottom cover bottom surface, also sets between interconnecting piece bottom surface and cathode bottom cover bottom surface
There are several the second cavitys, interconnecting piece one end is equipped with protrusion, and protrusion is protruded into inside fluid fixed block, hooks folding part and cathode bottom cover is equal
Venthole is offered, venthole is matched with the first cavity and the second cavity.
Further, venthole is designed using broad mouth type.
Further, the minimum diameter of venthole is 0.5-1mm, maximum inner diameter 1.5-2mm.
Further, venthole is also mating is provided with air ventilation membrane.
Further, sealing ring, which is also matched, is arranged with buffer compartment piece, and buffering partition is fixedly connected with sealing ring.
Further, buffering partition one end is protruded into inside fluid fixed block.
The utility model has the advantages that
Traditional blast resistance construction design is eliminated, it is anti-to reach pressure release to cooperate venthole by the first cavity and the second cavity
Quick-fried purpose, on the one hand, when inside battery generates gas, these gases can oppress sealing ring and it is made to resist cathode bottom cover,
The air of the deformation of sealing ring generation at this time, the first cavity and the second cavity inside will be externally discharged by venthole, another party
Face, recess portion come into full contact with hook folding part and cathode bottom cover end, avoid the possibility that leakage occurs for battery, sealing ring realizes anti-
It is quick-fried and avoid the double action of leakage, while reducing and occupying inside battery space, battery capacity has been effectively ensured；Venthole uses
The case where broad mouth type designs, and avoids dust accretions generation；Air ventilation membrane can effectively prevent dust and enter venthole and not influence to ventilate
The normal work in hole；Sealing ring, which is also matched, is arranged with buffer compartment piece, and buffering partition is fixedly connected with sealing ring, works as cell internal pressure
When larger, buffering partition can play the role of compensator or trimmer pressure, and sealing ring pressure has been effectively relieved.
