BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage battery mounted on an automobile, a motorcycle or the like, which allows an internal electrolyte to be easily confirmed from the outside.

[0002]

2. Description of the Related Art A conventional storage battery as described above is
Since a milky white synthetic resin is used as the material due to the relationship with the electrolytic solution and the like, it is difficult for the outside to immediately know the amount of the electrolytic solution from the outside. That is, since the electrolytic solution is transparent, the boundary between the electrolytic solution surface and the air layer is unclear. Therefore, in the past, in order to know the amount of the electrolytic solution, the storage battery was shaken to change the liquid level for confirmation.

[0003]

However, in the method of shaking the storage battery as described above, it was not possible to know the exact amount of the electrolytic solution in a stationary state due to the shaking of the liquid surface. Therefore, as a solution to the above-mentioned drawbacks, there is one in which a liquid level indicator is provided on the upper surface of the storage battery. In recent storage batteries, the inside of the casing is divided into a plurality of battery cases, Since the electrode plate and the electrolytic solution are filled in the above, it is necessary to provide the above-mentioned indicator in each battery case, and only one is provided because the cost is high. Therefore, for all battery containers There was a problem that it was not possible to know the total amount of liquid.

The present invention is intended to solve the above-mentioned problems, and its purpose is to make the boundary between the electrolytic solution surface and the air layer clear so that the liquid surface for all batteries can be improved. Can be easily confirmed, and further, the natural evaporation of the electrolytic solution and the deterioration of the electrolytic solution due to fine particles from the outside air can be prevented, and the evaporation of the electrolytic solution is less likely to occur during charging, and the cost is reduced. The purpose is to provide a storage battery that can be lowered.

[0005]

Means for Solving the Problems The storage battery of the present invention is intended to achieve the above-mentioned object. The means is that the inside is divided into a plurality of battery cells, and an electrode plate and an electrolytic solution are provided in each battery cell. In a milky white storage battery filled with, the specific gravity is lighter than the electrolytic solution in each battery case, and a colored liquid that does not deteriorate the electrolytic solution and does not adversely affect the electrode plate It is floated.

[0006]

In the storage battery of the present invention configured as described above, since the colored liquid floats on the surface of the electrolytic solution, the colored liquid is present between the electrolytic surface and the air tank. The liquid surface, which is the boundary between the surface and the air layer, becomes clear, so that the liquid amount of the electrolytic solution can be easily confirmed.

Further, in the case of a colored liquid, since it spreads over the entire liquid surface of the electrolytic solution, it is possible to prevent natural evaporation of the electrolytic solution and deterioration of the electrolytic solution due to fine particles from the outside air. It is difficult for the evaporation of

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the storage battery of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a box-shaped casing made of milk-white synthetic resin, inside of which partition walls 1a are arranged at predetermined intervals. It constitutes the battery case 1b. 2 is each battery case 1
An electrode plate made of lead or the like contained in b, 3 is an electrolytic solution which is also dilute sulfuric acid filled in each battery case 1b, and 4 is an electrolytic solution 3 formed on the cover plate 1c of the casing 1. It is a cap screwed into the hole for. The above configuration is the same as that of a known storage battery.

Reference numeral 5 is a colored liquid which has a lower specific gravity than the electrolytic solution 3 floating on the upper surface of the electrolytic solution 3, and does not deteriorate the electrolytic solution and does not adversely affect the electrode plate. The liquid temperature of the electrolytic solution 3 of the colored liquid 5 is 60 ° C.
Therefore, it is preferable that the liquid has a specific gravity of less than 1.2, is acid-resistant, and has high fluidity with temperature resistance, and that is low in cost.

Examples of the oils and fats include mineral oils and artificial oils, paraffins such as octane and decane, and aromatics such as anisole and phenetole. It should be noted that a granular solid such as styrofoam, which is a synthetic resin containing gas instead of the colored liquid, may be colored with a pigment or the like.

As described above, the colored liquid 5 or the colored solid, which has a lower specific gravity than the electrolytic solution 3 and does not deteriorate the electrolytic solution 3 and does not adversely affect the electrode plate 2, is contained in the electrolytic solution 3. By floating on the surface, one horizontal stripe can be clearly seen when viewed from the side of the casing 1, so that the height of the liquid surface can be easily determined, and therefore, the amount of the electrolyte 3 is replenished. This will make it easier to decide if you need to do so.

Further, particularly in the case of the colored liquid 5,
Since the entire surface of the electrolytic solution 3 is covered, natural evaporation of the electrolytic solution 3 can be prevented, acid mist is less likely to occur during charging, and fine particles and the like from the outside air are not generated in the casing 1.
Even if it penetrates into the inside, it does not enter the electrolytic solution 3, so that the deterioration of the electrolytic solution 3 can be prevented.

[0013]

As described above, the present invention provides a colored liquid which has a specific gravity smaller than that of the electrolytic solution in each cell, does not deteriorate the electrolytic solution, and does not adversely affect the electrode plate. By suspending the liquid, the boundary between the electrolyte surface and the air layer becomes clear, and the liquid surface can be easily confirmed for all battery cases. Moreover, the natural evaporation of the electrolyte and the fine particles from the outside air It is possible to prevent deterioration of the electrolytic solution due to
In addition, it is possible to prevent the evaporation of the electrolytic solution during charging and to reduce the cost.
