The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

As shown in fig. 1, the utility model provides an alkaline battery steel casing of overlength shelf life, including steel casing body 10, insulating cover 20 and dampproofing cover 30, insulating cover 20 sets up in steel casing body 10 outsidely, dampproofing cover 30 sets up at insulating cover 20 outsidely, insulating cover 20 is the vapor structure, be equipped with a plurality of bleeder vents 21, every bleeder vent 21 is close to the fixed closed piece 22 of one end of dampproofing cover 30, closed piece 22 can only overturn to the outside, dampproofing cover 30 top is equipped with thermovent 31, be equipped with the clearance between dampproofing cover 30 and the insulating cover 20, and the enough closed piece 22 upset of width in clearance. Although the insulating sleeve 20 has the air holes 21, the moisture-proof sleeve 30 is also sleeved outside, and the material of the moisture-proof sleeve 30 is also insulating, so that the leakage of electricity on the circumferential surface of the battery is not caused, and the outside of the battery is also insulating.

The steel shell body 10 is as the anodal mass flow body of alkaline cell, and dampproofing cover 30's effect is for providing dampproofing protective screen for the battery, stops inside too much aqueous vapor enters into the battery, can also absorb the inside aqueous vapor of battery, prevents that the inside humidity of battery is too high, and insulating cover 20's effect is for providing insulation protection, prevents that battery circumference face electric leakage from causing the short circuit.

As shown in fig. 1, when hot gas or moisture is transferred from the inside of the battery through the airing holes 21, the gas collides with the closing piece 22, so that the closing piece 22 is turned outwards, thereby releasing the shielding of the airing holes 21, hot gas or moist gas inside the battery is emitted, and the closing piece 22 can prevent the moisture absorbed by the moisture-proof cover 30 from entering the airing holes 21 again.

It should be noted that the shape of the closing piece 22 may be any shape, and it may be a circle or a square, as long as it can block one end of the outside of the ventilation hole 21 and can be turned outwards.

As shown in fig. 1 and fig. 3, specifically, a fixing seat 23 and a limiting block 24 are arranged inside one end of the air hole 21 close to the moisture-proof sleeve 30, the fixing seat 23 and the limiting block 24 are symmetrical by taking the central axis of the air hole 21 as a symmetry axis, one end of the closing piece 22 is fixed to the fixing seat 23, and the length of the closing piece 22 is greater than the distance between the fixing seat 23 and the limiting block 24. In the initial state, one end of the closing piece 22 is fixed on the fixing seat 23, and the other end of the closing piece 22 is lapped on the outer side surface of the limiting block 24. When air comes out from the air holes 21, the air pushes the closing piece 22 outwards, one end of the closing piece 22 close to the limiting block 24 is turned outwards, and the air comes out from the air holes 21. When the gas inside is no longer present, the closure flap 22 returns to its original state.

The closing piece 22 is fixed to the fixing base 23 by bonding or sewing. The insulating sleeve 20 is made of paper, plastic, rubber, etc. Preferably, the closing piece 22 is made of a fabric, the fabric is soft and not easy to break, the air from the air holes 21 can prop against the closing piece 22, and the closing piece 22 is made of the fabric, so that the closing piece 22 can be bent outwards or turned outwards, and the shielding of the air holes 21 is released.

As shown in fig. 1, the moisture-proof cover 30 includes a waterproof film layer 32, a moisture-absorbing fiber layer 34 and a desiccant layer 33 from the outside to the inside, and the waterproof film layer 32 is a conventional one, and is made of any material as long as it can perform a waterproof function. The waterproof membrane layer 32 plays a role in blocking external moisture from entering, the drying agent layer 33 plays a role in absorbing moisture from the air holes 21, and the moisture absorption fiber layer 34 absorbs and transfers the moisture in the drying agent layer 33, so that the drying agent layer 33 keeps moisture absorption capacity, a saturation state is avoided, and the moisture from the air holes can be continuously absorbed. The absorbent fibrous layer 34 itself is drained of moisture through both ends thereof.

As shown in fig. 1 and 2, the desiccant layer 33 includes a sandwich layer 331 and a desiccant, a through hole 331a is formed at the top of the sandwich layer 331 or at the bottom of the sandwich layer 331, the through hole 331a is provided with a plug 331b, the through hole 331a is used for the introduction or removal of the desiccant, and the plug 331b is used for sealing the through hole 331a to prevent the desiccant placed in the sandwich layer 331 from leaking out. When the drying agent loses the moisture absorption capacity after being used for a long time, the old drying agent can be taken out from the through hole 331a and then replaced by a new drying agent. Certainly, the drying agent belongs to the product in the prior art, and the drying agent can be used in any formula and process, so long as the drying agent has the function of absorbing moisture. The interlayer 331 is made of water-absorbing material, so that moisture can be transmitted through the interlayer 331, the desiccant, the interlayer 331, and the moisture-absorbing fiber layer 34 after coming out of the air holes 21.

In order to prevent the plug 331b from being easily lost when removed from the through hole 331a, the plug 331b is connected to the outer wall of the interlayer 331 by a connecting rib 331 c.

As shown in fig. 1-2, some of the relatively hot gases will float above the moisture barrier 30 and may be discharged through the vents 31. The heat dissipation port 31 is provided with an automatic opening and closing structure 35, and when hot air needs to be discharged from the heat dissipation port 31, the automatic opening and closing structure 35 can be automatically opened, and can be automatically closed after exhausting.

As shown in fig. 1, 2 and 4, in order to adapt to the automatic opening and closing structure 35, the shape of the heat sink 31 is circular, the automatic opening and closing structure 35 includes a plurality of blocking pieces 351 uniformly arranged on the periphery of the heat sink 31, and the bottoms of the blocking pieces 351 are all fixed on the periphery of the heat sink 31. In an initial state, the top of the blocking piece 351 is positioned on the central axis of the heat dissipation opening 31, so that the tops of all the blocking pieces 351 lean against each other; when the heat dissipation opening 31 has hot air to come out, the top of the blocking pieces 351 is pushed open, the hot air is discharged, and the tops of all the blocking pieces 351 are restored to be in a mutually leaning state, so that external water vapor cannot enter from the heat dissipation opening 31.

As shown in fig. 3, the outer side surface of the stopper 24 is an inclined surface so that the closing piece 22 can be fitted to the stopper 24 in the initial state to prevent a gap from being formed between the closing piece 22 and the stopper 24.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. This need not be, nor should it be exhaustive of all embodiments. And obvious changes and modifications can be made without departing from the scope of the invention.
