従来においては密閉構造をとる機器に対する充電可能な
電池の使用は避けられていた。Batteries such as nickel-cadmium sigma batteries and lead-acid batteries are used in this type of equipment, but these batteries
The water in the battery is electrolyzed to produce hydrogen gas and oxygen gas. These hydrogen gas and oxygen gas generated by normal charging are recombined inside the battery and converted into water. However, if the amount of both gases generated exceeds the ability to recombine them and increases the internal pressure of the battery,
Both gases are released outside the battery through a safety valve installed in the battery. Here, there is no problem if the inside of the device is open to the atmosphere, but if the device has a sealed structure such as waterproofing, the above-mentioned gases may be released. If the hydrogen gas fills the equipment and increases the internal pressure, hydrogen gas may explode due to contact arcs of switches or commutator arcs in the equipment, damaging the equipment or causing harm to the human body. There is a risk of it getting lost. For this reason, in the past, the use of rechargeable batteries in devices with sealed structures has been avoided.

The anode terminal portion forms a minute gap that serves as a gas vent hole between the sealing plate, the valve body that contacts the hole in the center of the sealing plate, and the valve body (covering the valve and on the sealing plate). It is composed of. A battery waterproof jt, Kl) is fitted onto one end of the anode side of the battery (7), except for the central part of the anode terminal, and is fixed with a covering rod η. This battery waterproof jL@υ is equipped with a connection port with the terminal waterproof jum (2), and the scum released from the safety valve is transferred from the space between the battery waterproof bell 0 and the battery (7) to the terminal. The water is discharged from a discharge hole provided apart from the waterproof part (2) and the recess (-) in which the terminal (to) is disposed on the bottom surface of the main body housing +1+. Terminal waterproof
The LH is for waterproofing the bottom of the main body housing f1), and is provided with an insertion part for a pair of charging terminals (B) that protrudes into the recessed part of the bottom of the main body housing +1'l. ) is fixed between the printed circuit board □□□ to which the base end of the main body housing +1+ is soldered and the inner bottom surface of the main body housing +1+. In addition, a diode 1 resistor and a light emitting diode 〇 for indicating charging status are attached to the printed circuit board. The mouse is a lamp cover for viewing through the light emitting diode circle. The anode metal fitting that contacts the anode terminal of the battery (7) contacts the switch spring handle, and

If something is blocked or a part is missing, or if a large amount of gas is generated during charging and gas leaks into the space inside the main body housing (1) from the safety valve to the discharge port, do the following: The gas is exhausted like this. In other words, a base housing a battery (6) and a battery (7).
21 A thin partition piece 1 is integrally provided to divide the interior of the main body into the battery compartment and the battery compartment. It is partitioned so that it communicates only with a certain degree of clear lasing, and hydrogen and oxygen gas generated from the battery (7) flows into the storage compartment.
It's Kuiyo K. Further, an exhaust hole is provided on the bottom surface of the main body housing fl) adjacent to the recess where the terminal side is arranged. This exhaust hole is located on the main body housing +1
) In order to seal the internal space, it is normally closed by a valve stem chamber provided at the top of the lever, which can be opened by connecting a charging adapter with a built-in charging circuit. An O-ring is attached to the valve stem at one end, and this O-ring is closed. A look at the valve stem and the return spring
They are arranged in series in the direction of the melting axis so that the spring force of the return spring group acts in the axial direction K11i of the valve stem. On the other hand, the charging adapter 4 that supplies the charging current is connected to the bottom of the main body housing il) as shown in Fig. 5, and is inserted into the recess and connected to both terminals. The terminal receiving part g2 and this terminal receiving part (which is equipped with a protruding boss round adjacent to 7) (boss ff1) push up the valve shaft S against the return spring to open the exhaust hole. . At this time, position the lever (6) with the thin insulating piece at its upper end between the swift spring 4 and the contact lug, and press the switch lever (6) regardless of the position of the switch lever (1). Cut off the electricity to the lever (to).The holding piece provided on the lever (to)

is the charging adapter's fourth terminal to be opened by the ninth terminal (
Although the recess 149) which accommodates the exhaust hole 149) is provided on the bottom of the main body housing (1) in parallel with the recess 149), it is also provided with the discharge port. The inner wall of the recess fr1491 exists as a partition wall between them, and the gas discharged from the exhaust hole and the discharge port hardly flows into the recess side, and the gas flows through the main body housing (1).
and the charging adapter 4. When charging is stopped, the valve stem T63i closes the exhaust hole with the return spring ■, and at the same time, the insulating piece (271) is lowered from the contact point, so the switch hash t63i is turned on and off due to odor. ] The tip of the valve stem chamber should protrude beyond the valve seat, and the boss (7υ) should be made slightly smaller in diameter than this tip, and the exhaust hole should be covered with the charging adapter 4 when the charging adapter 1 is installed. The reason for this is to prevent dirt from entering when the exhaust hole is closed when not charging and during charging.
A hydrogen-oxygen reaction catalyst 16υ is placed on the surface of the base (2) on the seventh (6) side of the partition system, which is located in the darkness between the battery (7) and the base (2), and the partition piece is removed. and main body housing (1
) The hydrogen and oxygen that have passed through the minute gap with the inner surface are turned into water. As the catalyst II), 0.5% by weight of palladium was adhered to the surface of alumina.

This can prevent the internal pressure of the device from rising and explosions within the device. Because it is a recess, the dead space inside the container can be effectively used, and the exhaust hole that can be opened and closed does not take up a large amount of space, and the recess can be used in parallel with the recess. However, since there is a partition wall between the exhaust hole and the recess, the gas released from the exhaust hole may flow into the recess where arcing occurs between the terminal and the terminal when the charging member is attached or removed. There is no chance of an explosion occurring in this area.
