INDUSTRIAL APPLICATION FIELD The present invention relates to a storage case for an air battery, such as a button-type air battery, which utilizes oxygen in the air flowing in through air holes provided in an exterior member of the battery as a positive electrode active material. Conventional Structures and Their Problems Conventionally, battery storage cases for equipment powered by button-type air batteries, such as hearing aids, have a structure that simply houses a battery and provides a contact piece that contacts its terminal. Therefore, the air holes provided in the battery itself are always open regardless of whether the power is turned on or off. Therefore, the following inconvenience occurs. (1) Even when the device is not in use, air is supplied through the battery's air holes, so carbon dioxide gas enters the battery and forms carbonates such as potassium carbonate in the electrolyte, causing damage to the inside of the battery. resistance increases. (2) Zinc in the negative electrode active material reacts with air and self-discharges, resulting in a decrease in battery capacity. (3) Moisture evaporates from the air holes, increasing internal resistance. To solve the above-mentioned problems unique to air batteries, the conventional method was to remove the battery from the device when not in use, seal the air holes with sealing tape, and then peel off the tape and place it in the device when it is used. It was common. According to this method, the battery can be attached to and removed from the equipment,
It is troublesome for the user to apply and remove stickers, and the battery is usually left in the storage case of the device, making it difficult to maximize the performance of the battery. Purpose of the Invention The present invention eliminates the above-mentioned conventional disadvantages,
To provide a battery storage case capable of maximizing the performance of an air battery by making it possible to close the air holes of the battery except when the battery is in use without requiring troublesome operations. Structure of the Invention The air battery storage case of the present invention is characterized in that it is provided with means for opening and closing the air holes of the air battery in conjunction with opening and closing of the power switch of the device. According to the configuration of the present invention, the air holes of the battery in the battery storage case of the device are automatically opened and closed only by turning the power on and off, so that it is not necessary to attach or remove the battery to the device or use the sealing tape as in the past. This eliminates the need for troublesome operations such as attaching and detaching batteries, and allows you to maximize the performance of your batteries. DESCRIPTION OF EMBODIMENTS First, the configuration of a button-type air cell will be explained with reference to FIG. This air battery 1 includes a battery case 2 having an air hole 2a at the bottom, a sealing plate 3, and a gasket 4 in which a power generating element is enclosed. 5 is a zinc negative electrode, 6 is an electrolyte impregnated material, 7 is a separator, 8
9 is a positive electrode catalyst layer, 9 is a water-repellent membrane, and 10 is an air diffusion paper. In this battery, oxygen in the air that passes through the air diffusion paper 10 and the water-repellent membrane 9 through the air holes 2a reaches the catalyst layer 8 and causes an electromotive reaction. Then, when the battery is not in use, the sticker table 1 is attached to the bottom of the case.
1 closes the air hole 2a. FIG. 2 shows a first embodiment of the battery storage case. Reference numeral 12 denotes a battery storage case provided in the main body of the device, and the battery 1 is fixed in the case with its air hole 2a facing upward. On the inner surface of the case 12, there is a contact piece 13 that comes into contact with the sealing plate 3 that constitutes the negative terminal of the battery.
and a contact piece 14 that makes up the positive terminal of the battery and contacts the side surface of the battery case 2. One contact piece 13 is connected to one end of the load 15 of the device, and the other contact piece 14 is connected to one end of the load 15 of the device. It is connected to a contact piece 16 provided exposed on the outer surface of the case 12. Reference numeral 17 denotes a power switch operation piece provided on the upper surface of the case so as to be able to slide left and right.It has a contact piece 18 connected to the load 15, and the power can be turned on and off by connecting and separating the contact piece 18 and the contact piece 16. It's something to turn off. Reference numeral 19 denotes a disk-shaped closing member provided on the upper wall of the case 12 to face the battery 1, and its shaft portion 19a
is attached to the upper wall of the case so that it can move up and down.
20 is a spring that always urges the closing member 19 upward. The figure shows that the air hole 2a of the battery 1 is open and the contact piece 18
and 16 are in contact and the power switch is on, but when the switch operation piece 17 is moved to the left, the sloped part 17a at the tip pushes down the shaft part 19a,
When the contact piece 18 moves to a position away from the contact piece 16, the closing member 19 contacts the battery case 2 and closes the air hole 2a. FIG. 3 shows a second embodiment. Reference numeral 21 denotes a battery storage case provided in the main body of the device, and the battery 1 is inserted into the case so as to be vertically movable. A contact piece 22 that contacts the negative terminal 3 of the battery is provided at the bottom of the case 21 and urged upward by a spring 23, and the spring 23 has sufficient pressure to press the battery 1 against the upper wall of the case. On the other hand, there are conductive contacts 24 on the upper wall of the case.
is biased upwardly by a spring 25 so as to be movable up and down, and a switch operation piece 26 that is slidable left and right is provided on the outer surface of the case. 27 is a load of the equipment, one end of which is connected to the contact piece 22.
, and the other end is connected to a contactor 24. In the figure, the contact 24 is pushed down by the operation piece 26, and the battery is also in a lowered position. Therefore, the air hole 2a of the battery is opened, and the contact 24 is in contact with the positive terminal of the battery. The power switch is on. Next, when the operating piece 26 is moved to the right, the contact 24 is released from the operating piece 26 and is pushed upward by the pressure of the spring 25. At the same time, the battery is pushed up by the spring 23 so that the battery case 2 comes into close contact with the upper wall surface of the case 21, and the air hole 2a is closed. In this state, the contact 24 is separated from the battery case 2, and the power switch is turned off. To turn on the switch, use the operating piece 26.
It is sufficient to move the contactor 24 to the left and push down the contactor 24 with the sloped portion 26a at the tip thereof, so that the contactor 24 is in the state shown in the figure. As described above, according to the present invention, since the air hole of the battery can be opened and closed in conjunction with the opening and closing of the power switch, handling is easy and performance deterioration when the battery is not in use can be prevented. For A when using the above battery storage case and B when the air hole is open, 10 volts per day at 2 mA.
Comparing the discharge duration when discharging in hours, the results are as shown in the table below. In other words, according to the present invention, the battery life is improved by about 30%.
