Description
Technical field
The utility model is related to alkaline battery technical fields, and in particular to a kind of alkaline battery cathode sealing structure.
Background technology
After the completing of the alkaline battery of generally cylindrical shape, since alkaline battery raw material are not exclusively pure, battery
Box hat electroplated layer is not fine and close enough, in addition, the environment of production can also introduce some impurity, hydrogen is easily analysed in these contaminant surfaces
Go out, so that the air pressure in battery increases and is likely to occur explosion.It is raw inside the alkaline battery of different battery producer production
Into tolerance it is different, the material purities of some producers is rigid in checking up by stringent control, production process, is generated in battery
Tolerance can be much smaller, but is not generally possible to prevent.Due to inevitably generating gas, inside battery pressure inside alkaline battery
Power can be more than atmospheric pressure, and such battery seal ring moment bears an outside stress, when battery cannot bear inside battery
After pressure, it may occur that the danger of explosion, the structure of existing battery are to set sealing ring, and explosion-proof valve is equipped on sealing ring,
Although can be explosion-proof, battery leakage can not be effectively avoided the problem that.
Utility model content
The purpose of this utility model is for technological deficiency in the prior art, and providing a kind of can effectively adjust electricity
To prevent from exploding the alkaline battery cathode sealing structure of simultaneously energy imbibition occurs for the outside exhaust in pond.
Technical solution is used by realize the purpose of this utility model：
A kind of alkaline battery cathode sealing structure, including negative cover and sealing ring, the negative cover connects negative pole currect collecting
Body, the sealing ring include newel, and the negative current collector stretches out, the cathode through the through hole at the newel center
Air vent has been covered, imbibition column is equipped between the sealing ring and the negative cover, has cavity, the cavity in the imbibition column
In have imbibition cotton, the side wall of the imbibition column has gas vent, and one end of the imbibition column contacts and the other end with the negative cover
It is contacted with the sealing ring and opposite with the explosionproof hole on the sealing ring, there is explosion-proof valve block in the explosionproof hole.
The imbibition column is two, is arranged symmetrically.
The one end open other end closing of the imbibition column.
The both ends open of the imbibition column.
The utility model is equipped with imbibition by there is air vent in negative cover between the sealing ring and the negative cover
Column has cavity in the imbibition column, has imbibition cotton in the cavity, the side wall of the imbibition column has gas vent, the imbibition column
One end contacted with the negative cover and the other end is contacted with the sealing ring and opposite with the explosionproof hole on the sealing ring, institute
Stating in explosionproof hole has explosion-proof valve block, can be washed the explosion-proof valve block open, gas enters suction when cell internal pressure is excessive
In column, gas is discharged through the gas vent on imbibition column side wall, into the space between negative cover and sealing ring, then from the cathode
The air vent discharge covered, the electrolyte discharged with gas enter imbibition column, are absorbed, will not be discharged to outside battery by imbibition cotton
Portion.
Description of the drawings
Fig. 1 is the structure diagram of alkaline battery cathode sealing structure.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
It is shown in Figure 1, a kind of alkaline battery cathode sealing structure, the sealing ring including negative cover 4 and plastic production
2, it is sealed between negative cover and battery case 1 by sealing ring 2, the outer part 12 of sealing ring 2 is placed in negative cover and battery case
Between, by the gap sealing between negative cover and battery case, the one side of sealing ring is in contact with negative cover 4, and opposite side is by battery
Annular groove clamping /V is formed on shell 1 in inside battery, the negative cover connects negative current collector 3, the sealing ring bag
Newel 5 is included, the negative current collector is stretched out through the through hole at the newel center, has air vent in the negative cover
11, imbibition column 8 is equipped between the sealing ring and the negative cover, has cavity in the imbibition column, has imbibition in the cavity
Cotton 9, the side wall of the imbibition column have a gas vent 10, one end of the imbibition column contacted with the negative cover and the other end with it is described
Sealing ring contact is simultaneously opposite with the explosionproof hole 6 on the sealing ring, there is explosion-proof valve block 7 in the explosionproof hole.
The explosion-proof valve block 7 is to remove certain thickness upper and lower sides part in the both sides up and down of explosionproof hole 6 on sealing ring
Sheet segment after residue, thickness are less than the thickness of the sealing ring, are an integral structure with sealing ring.
Wherein, the imbibition column is two, is arranged symmetrically, and not only plays the role of imbibition, the work also with support negative cover
With, together with newel to negative cover formed support, prevent battery cathode cover sealing when be crushed out of shape.

The utility model is equipped with imbibition by there is air vent in negative cover between the sealing ring and the negative cover
Column has cavity in the imbibition column, has imbibition cotton in the cavity, the side wall of the imbibition column has gas vent, the imbibition column
One end contacted with the negative cover and the other end is contacted with the sealing ring and opposite with the explosionproof hole on the sealing ring, institute
Stating in explosionproof hole has explosion-proof valve block, can be washed the explosion-proof valve block open, gas enters suction when cell internal pressure is excessive
In column, gas is discharged through the gas vent on imbibition column side wall, into the space between negative cover and sealing ring, then from the cathode
The air vent discharge covered, the electrolyte discharged with gas enter imbibition column, are absorbed, will not be discharged to outside battery by imbibition cotton
Portion.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
