Abstract
The utility model discloses a alkaline battery closing structure, which comprises bottom cover with annular groove and exhaust vent on bottom cover, the utility model is characterized in that: said exhaust vent has at least one part is at inner ring side wall of bottom cover annular channel. The utility model increases safety performance of the battery in case of incorrect use by improving distribution position of metal negative pole bottom cover exhaust vent, aperture size and hole quantity.
Description
Technical field
The utility model relates to a kind of alkaline battery, refers in particular to the alkaline battery that a kind of metal negative pole bottom by improvement seal body part improves battery safety.
Background technology
Production equipment, prescription, accessory structure and the technical matters of the most Imported Japan FDK of the early stage alkaline battery of China.Present alkaline battery, its structure is made of box hat, electrically conductive graphite, anode ring, barrier paper, negative zinc cream, battery seal body etc.The battery seal body structure is made up of envelope sealing ring 1 and current collection 2 as shown in Figure 1.Sealing ring 1 is injection molded by nylon or polypropylene homogenous material, and periphery is provided with explosion-proof ditch.Current collection 2 comprises a bottom 3, and bottom 3 has ring-shaped groove 31, is provided with steam vent 32 in the bottom and sealing ring 1 position contacting of bottom groove 31.The explosion-proof ditch on the sealing ring 1 and the effect of the steam vent 32 on the bottom 3 are to improve the explosion-proof performance of battery.
Yet the battery of this structure in use still has explosion phenomenon, exists potential safety hazard.The inventor is through studying discovery for a long period of time, when battery during in incorrect use, for example battery reversal connection in 3: 1, new used batteries are used with, battery short circuit, under situations such as battery charge, battery body may produce a large amount of heats, adding the expansion of inside battery gas can make the sealing ring 1 of seal body produce distortion with increase, very easily make the steam vent 32 on seal body sealing ring 1 and the metal negative pole bottom 3 tightly suffer in this case, cause 32 blocked being difficult to of steam vent to play a role, cause inside battery gas smooth and easyly not discharge, in case the gas pressure of inside battery is accumulated to certain degree, will cause the explosion of battery container.
The utility model content
The hidden peril of explosion that exists at present alkaline battery, the purpose of this utility model is to eliminate the potential safety hazard that battery exists by the metal negative pole bottom cover structure of improvement seal body part under incorrect operating position, and a kind of portable power supplies of safety and reliability is provided to the user.
To achieve these goals, the utility model technical solution is: the alkaline battery seal body structure, comprise the bottom of band shape groove and the steam vent on the bottom, it is characterized in that: described steam vent to small part is positioned on the inner ring sidewall of bottom ring-shaped groove.
Described steam vent can adopt 2 can obtain effect preferably for one or more usually, and the battery volume adopts the steam vent of a greater number when big, hour then can adopt less steam vent quantity.
Big few size according to battery of steam vent is set, and diameter is advisable with 0.8-1.5mm.
The utility model is by changing the distributing position of metal negative pole bottom steam vent, make it have at least a part to be positioned on the inner ring sidewall of bottom cannelure, even battery uses under incorrect situation, when the explosion-proof ditch of seal body sealing ring works, can not stop up steam vent yet, inside battery gas can smooth and easyly be discharged, eliminated battery and under incorrect situation, used the potential safety hazard that explosion takes place, improved the security performance that battery uses greatly.Adopt the seal body metal negative pole bottom of said structure, through verification experimental verification repeatedly, the security performance of battery is improved.
Description of drawings
Below the utility model is done further detailed description to closing accompanying drawing:
Fig. 1 is existing alkaline battery seal body structure cutaway view.
Fig. 2 is an alkaline battery seal body structural representation of the present utility model.
Embodiment
Below with reference to accompanying drawing the utility model is carried out detailed description.
Please refer to shown in Figure 2, alkaline battery seal body is made up of sealing ring 1 and current collection 2, current collection 2 is formed by high frequency spot welding by the copper pin 4 of zinc-plated or indium and metal negative pole bottom 3, and the metal negative pole bottom 2 with this structure can be used for alkaline series battery such as LR20, LR14, LR6, LR03 or has in the battery of same structure; Seal body sealing ring 1 is injection molded by nylon or polypropylene homogenous material, is provided with centre bore in the middle of the sealing circle, and periphery is provided with explosion-proof ditch, and the copper pin 4 of current collection passes the centre bore of sealing ring 1, and forms interference fit with sealing ring 1.The bottommost that the steam vent 32 of the metal negative pole bottom 3 of current collection contacts with sealing ring from the negative pole bottom moves on to the inner ring side-walls of the ring-shaped groove 31 of metal negative pole bottom 3, even sealing ring 1 is adjacent to metal negative pole bottom 3 and also can stop up this steam vent 32 when making the cell internal pressure increase, can eliminate the potential safety hazard of battery battery generation explosion under incorrect operating position.
As required, also can enlarge the quantity of the pore size and the increase steam vent of steam vent simultaneously, pore size can be 0.80-1.5mm, generally is advisable with 1.0mm, and the quantity of steam vent increases to two even more a plurality of.
Claims (3)
1, a kind of alkaline battery seal body structure comprises the bottom of being with cannelure and the steam vent on the bottom, and it is characterized in that: described steam vent has at least a part to be positioned at the inner ring side-walls of bottom ring-shaped groove.
2, alkaline battery seal body structure as claimed in claim 1 is characterized in that: described steam vent is two or more.
3, alkaline battery bottom seal body structure as claimed in claim 1 or 2, it is characterized in that: the diameter of described steam vent is 0.80-1.5mm.
