According to the lead accumulator 100 of present embodiment forming in the above described manner, multiple independent exhaustion mouth 3b that will be arranged as linearity by the exhaust flow path 3c of linearity connect, thereby can make the structure of exhaust flow path 3c become simple.
And, in this structure, be provided with multiple spaced walls 9, the plurality of spaced walls 9 is to separating between independent exhaustion mouth 3b adjacent one another are and between outermost independent exhaustion mouth 3bx and unified exhaust outlet 3c3, and the top in exhaust flow path 3c rely on the plurality of spaced walls 9 and be formed with gas pass through between 3S, therefore, flow and flow to unified exhaust outlet 3c3 in the top from each independent exhaustion mouth 3b effluent air in the exhaust flow path 3c of linearity, thus easy Exhaust Gas.On the other hand, the bottom in exhaust flow path 3c is separated by multiple spaced walls 9, and the electrolyte that therefore can suppress to flow out from each independent exhaustion mouth 3b flows out to outside batteries from unified exhaust outlet 3c3 via exhaust flow path 3c.
In addition, due to multiple spaced walls 9(9a) to separating between independent exhaustion mouth 3b adjacent one another are, therefore can prevent that the electrolyte flowing out from each independent exhaustion mouth 3b from moving to other independent exhaustion mouth 3b, thereby can prevent the deviation of the electrolyte generation in each element cell.
And then, owing to being provided with multiple spaced walls 9 at exhaust flow path 3c, therefore, from each independent exhaustion mouth 3b effluent air, contained acid mist (acid mist) contacts with multiple spaced walls 9 and reverts to drop, and then remove acid mist by the baffle plate effect of spaced walls 9, thereby can reduce the amount of the unified exhaust outlet 3c3 of acid mist arrival.
In addition, owing to being provided with porous part 8 at exhaust flow path 3c, therefore can utilize porous part 8 and slow down the speed that this electrolyte flows out to outside, thereby the electrolyte that can suppress to flow out from electric groove 2 to exhaust flow path 3c flows out to outside batteries via this exhaust flow path 3c.Herein, owing to being provided with spaced walls 9 between multiple independent exhaustion mouth 3b and porous part 8, therefore can reduce the amount of the electrolyte that arrives porous part 8, thereby can prevent from causing the eyelet of porous part 8 to stop up because electrolyte is impregnated in porous part 8.
And then, pass through direction down due to what be configured to gas in porous part 8, therefore, even if electrolyte is impregnated in porous part 8, the moving direction of the electrolyte of this impregnation down, with gas to pass through direction identical, the electrolyte of impregnation is not only because gravity moves down, also moved down by gas extrusion, thereby electrolyte also can not be stranded in the intake section of porous part 8, degassing function can not stop completely.Therefore, according to present embodiment, play following superior effect, that is: the in the situation that of battery 100 overturning, liquid is difficult to flow out to outside, even also can bring into play degassing function after restoring from overturning.
In addition, the utility model is not limited to above-mentioned execution mode.
For example, in the above-described embodiment, between independent exhaustion mouth 3b adjacent one another are and between outermost independent exhaustion mouth 3bx and unified exhaust outlet 3c3, be respectively provided with a spaced walls 9 although be configured to, also can be formed as between above-mentioned independent exhaustion mouth 3b adjacent one another are and outermost independent exhaustion mouth 3bx and the structure of unifying to be provided with between exhaust outlet 3c3 plural spaced walls 9.Thus, can further suppress to flow out to outside batteries from unified exhaust outlet 3c3 via exhaust flow path 3c from the electrolyte of independent exhaustion mouth 3b outflow.
In addition, although the spaced walls 9 in above-mentioned execution mode is formed as mutually the same shape, their shape also can be different.For example, can be formed as spaced walls 9 the closer to the structure of the larger grade of its height dimension of unified exhaust outlet 3c3.
And then, in the above-described embodiment, although be only formed as being provided with spaced walls 9 and the structure of spaced walls 9 not being set at upper cover 32 at groove 31M,, also can spaced walls 10 be set at upper cover 32.For example, as shown in Figure 6, also can be in the left side of the spaced walls of groove 31M 9 (side contrary with unified exhaust outlet 3c3) and/or right side (unified exhaust outlet 3c3 side) spaced walls 10 to be set with the opposed mode of above-mentioned spaced walls 9.This spaced walls 10 is arranged at the top in exhaust flow path 3b and the bottom in exhaust flow path 3c and is formed with gas and passes through space.As above, be also provided with spaced walls 10 except spaced walls 9, the electrolyte that can further suppress thus to flow out from each independent exhaustion mouth 3b flows out to outside batteries from unified exhaust outlet 3c3 via exhaust flow path 3c.In addition, acid mist (acidmist) contained from each independent exhaustion mouth 3b effluent air is because contacting and revert to drop with multiple spaced walls 9 and spaced walls 10, and then remove acid mist by the baffle plate effect of spaced walls 9 and spaced walls 10, thereby can further reduce the amount of the unified exhaust outlet 3c3 of acid mist arrival.
In addition, although the chimeric chimeric wall 311z of the filtration forming at groove 31M that is arranged at of porous part 8 in above-mentioned execution mode, but also can be formed as following structure: do not arrange and filter chimeric wall 311z, but make porous part 8 be embedded into downward stream 3c2(through hole 311x).In this case, also do not bring into play function as spaced walls for porous part 8 is chimeric even if filter chimeric wall 311z, therefore the chimeric wall 311z of this filtration is preferably set.
In addition, although the downward stream in above-mentioned execution mode be oriented vertical downwards, downwards stream towards also can be towards oblique below.As the shape of downward stream, except linearity, can be also bending shape or the shape of flexing.
And then, on this basis, although the downward stream forming portion in above-mentioned execution mode is formed as approximate L word shape, but, in addition, as long as forming the shape of downward stream, can be to be also formed with the right-hand end of groove 31M and to be formed with the jut of through hole 311x in inside at upper surface.
In addition, the utility model is not limited to above-mentioned execution mode, self-evident, can in the scope that does not depart from its purport, carry out various distortion.
