The utility model alkaline battery arranges suitable pore and sealing block in sealing ring main body, and when battery internal gas pressure increases, sealing block, by jack-up, discharges unnecessary gas.After air pressure recovers normally, in the downward landing of effect lower seal piece of spring, by stomatal closure, the phenomenon that can not cause liquid to flow out.On end cap, be provided with filter air film, the acid mist that can get rid of steam vent filter, and can avoid the pollution of acid mist to environment, air, and also can stop that naked light scurries in the steam vent of end cap, thereby prevent that the hydrogen of discharging and oxygen and naked light from reacting and blasting, and has explosion-proof.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with Figure of description, embodiment of the present utility model is described in detail.
The basic structure of the utility model alkaline battery is identical with existing battery.As shown in Figure 1, this alkaline battery mainly comprises shell 1, and one end sealing of shell 1, is provided with the projection 11 as positive terminal; From then on the other end opening of shell 1, for adding various internal structures.In shell 1, be provided with tubbiness barrier film 4,1, barrier film 4 and shell arrange positive pole 2, the interior negative pole 3 that arranges of barrier film 4.In anodal 2 material, include manganese dioxide, in the material of negative pole 3, include zinc.In negative pole 3, be provided with cylindrical header 5.
Shell 1 opening part is provided with end cap 7, utilizes end cap 7 by the closure of openings of shell 1, makes outside batteries form the housing of a sealing.The edge of shell 1 and end cap 7 can be used various connected modes, can weld, riveted joint or crimping.End cap 7 belows are provided with sealing unit, and the main application of sealing unit is in order to prevent the leakage of liquid in battery, simultaneously also for exitting with step-down when air pressure inside is excessive.The mounting means of sealing unit is not limit, and the edge that preferred structure is sealing unit is folded in the edge of shell 1 and end cap 7, uses the methods such as welding, riveted joint or crimping to be fixed.
Sealing unit in the utility model comprises annular seal ring main body 61, and current collector 5 inserts in negative pole 3 through the hole in sealing ring main body 61.Whole battery operated more stable in order to make, current collector 5 fixes by sealing ring main body 61.Edge in the hole of sealing ring main body 61 arranges boss, is conducive to the fixing of 61 pairs of current collectors 5 of sealing ring main body.
In order to discharge in time gas with decompression when battery air-pressure is excessive, in sealing ring main body 61, be provided with at least one taper pore 65, taper pore 65 is provided with suitable sealing block 62, one end of sealing block 62 linking springs 63, the other end of spring 63 connects end cap 7, and spring 63 is in compressive state, and pore and sealing block are all set to taper and are conducive to air pressure inside when too high, sealing block lifts, and makes pore open and exit; After air pressure is normal, sealing block slides along pore inside, has realized well the sealing of battery container.
The effect of spring 63 is, after battery internal gas pressure recovers, sealing block 62 is pushed back to original position, and when there is no air pressure, spring 63 makes sealing block closely be connected with pore, prevents liquid outflow.Between the sealing ring main body 61 of end cap 7 and below, leave certain space, when inside battery air pressure exceeds standard when few, this space is enough to hold unnecessary gas, in this space, be provided with pressure sensor, pressure sensor sends the force value of sensing to controller, controller contrasts the force value receiving and the force value setting in advance, if the force value receiving is greater than the force value setting in advance, controller is controlled the electromagnetism cap unlatching being arranged on filter air film, the too much gas that inside battery produces is released into outside the housing of battery by the pore 71 on end cap 7 and filter air film 72.
In order to be provided with at least one steam vent 71 on end cap 7 by the unnecessary air release of inside battery to the housing of battery, preferred quantity is two.When the air pressure of inside battery surpasses setting, gas enters in the space between end cap 7 and sealing ring main body 61 after discharging by taper pore 65, then through steam vent 71, be discharged to outside battery, on steam vent 71, be provided with filter air film 72, particularly tetrafluoroethene is filtered air film, compared with prior art, because tetrafluoroethene filter air film has excellent physics, chemical characteristic, noninflammability, resistance to acids and bases, the feature such as strong oxidizer and resistance to insulation, be that tetrafluoroethene filter air film can filter and get back in electrolyte the acid mist of steam vent discharge, can avoid acid mist to environment, the pollution of air, and also can stop that naked light scurries in steam vent, thereby prevent that the hydrogen of discharging and oxygen and naked light from reacting and blasting, there is explosion-proof.
