A resin main body case 6 having a battery storage portion 5 for storing the dry battery 4
And a switch 7 for energizing the miniature ball 2 and the battery 4.

A switch 7 is provided. Here, O-rings 8 are attached to the fitting portion of the main body case 6 and the front base 1 and the mounting portion of the main body case 6 for the switch 7, respectively, when these electric lights are used in water or rain. Water is prevented from flowing into the lamp through the gap.

【発明が解決しようとする課題】しかしながら、３個以
上の乾電池を直列接続して用いる防水型携帯電灯では、
１個の乾電池を誤って逆向きに接続した状態で通電を行
うと、その電池のみが他の電池によって充電状態にな
る。However, in a waterproof portable electric lamp which uses three or more dry batteries connected in series,
If one dry battery is mistakenly connected in the opposite direction and then energized, only that battery will be charged by the other battery.
【０００８】ここで、通常、乾電池では、正極に二酸化
マンガン（ＭｎＯ2）、負極に亜鉛（Ｚｎ）、電解液に
は塩化亜鉛（ＺｎＣｌ2）と塩化アンモニウム（ＮＨ4Ｃ
ｌ）を溶解した水溶液を用いている。In a dry battery, manganese dioxide (MnO 2 ) is used for the positive electrode, zinc (Zn) is used for the negative electrode, and zinc chloride (ZnCl 2 ) and ammonium chloride (NH 4 C) are used for the electrolyte.
An aqueous solution in which 1) is dissolved is used.
【０００９】そして、この乾電池は好ましくない充電状

ガスおよび酸素ガスが多量に発生していた。さらに、水
の電気分解の後半には電解液に含まれる塩化アンモニウ
ム（ＮＨ4Ｃｌ）と塩化亜鉛（ＺｎＣｌ2）の分解によっ
て窒素ガスなどが発生していた。When this dry battery falls into an unfavorable charged state, a large amount of hydrogen gas and oxygen gas are generated mainly due to electrolysis of water in the electrolytic solution. Furthermore, in the latter half of the electrolysis of water, nitrogen gas and the like were generated due to the decomposition of ammonium chloride (NH 4 Cl) and zinc chloride (ZnCl 2 ) contained in the electrolytic solution.
【００１０】また、上記のように多数のうち一部の乾電
池のみを逆向きに接続した状態では、豆球は少し暗く点
灯するがそのまま点灯を続けるため、電灯の使用者は、
電池を誤って逆に接続したことに気付かないまま電灯の
使用を続けることがあった。In addition, as described above, when only some of the dry batteries are connected in the reverse direction, the miniature ball lights up slightly darkly but continues to light up.
I sometimes continued to use the light without noticing that I accidentally connected the battery backwards.
【００１１】そして、この電灯の使用中に発生した水素
や酸素などのガスは電池内部に充満した後、電池のかし
め部分に生じた隙間などから電池外部に漏れ出し、電灯
の本体ケース内に徐々に蓄積していた。After the gas such as hydrogen and oxygen generated during the use of the electric lamp is filled inside the battery, it leaks to the outside of the battery through a gap formed in the crimped portion of the battery and gradually enters the main body case of the electric lamp. Had accumulated in.
【００１２】さらに、防水型携帯電灯は、外部からの水
の浸入を防止するために密閉構造になっており、これが
ために電池内部の気体の外部への放出も妨げられてい
る。Further, the waterproof portable electric lamp has a closed structure in order to prevent water from entering from the outside, which prevents the gas inside the battery from being released to the outside.
【００１３】したがって、本体ケース内で逆向きに接続
した電池から漏れ出した水素や酸素などのガスは本体ケ
ースの電池収納部からケース外部に放出されることな
く、本体ケース内に充満蓄積していた。Therefore, the gas such as hydrogen and oxygen leaked from the battery connected in the opposite direction in the main body case is not discharged from the battery accommodating portion of the main body case to the outside of the case, but is fully accumulated in the main body case. It was

ケース内に露出して存在するため、これらの接片の接触
時や、携帯電灯の落下時などに本体ケースの内部に火花
が生じると、この火花がこれらの充満蓄積したガスに引
火し、電灯が爆発するという危険性があった。Since the contact piece guided from the battery and the contact piece guided from the miniature ball are exposed inside the main body case when the switch of the portable electric lamp is operated, these contact pieces are in contact with each other and the portable phone. If a spark is generated inside the main body case when the light falls, the spark ignites these accumulated and accumulated gas, and there is a risk that the light will explode.

った。When the interior of the lamp is filled with gas such as hydrogen or oxygen, the gas pressure is applied to both contact pieces for energizing the battery and the miniature ball, and distortion is generated in that part, and when the switch is turned on. Poor contact sometimes occurred between both contact pieces.

被覆したものである。In order to solve the above-mentioned problems, a waterproof portable electric lamp according to the present invention has a reflector having a front base provided with a lens and a hemispherical part having a bean ball in the center. And a main body case having a battery storage portion for storing a plurality of power supply batteries, and a switch for energizing the miniature ball and the battery, and a battery storage portion and a main body case external part are provided in a part of the main body case. The ventilation hole which ventilates is provided, and this ventilation hole is
It is coated with a microporous film that is permeable to air but impermeable to water.

る。In the waterproof portable electric lamp according to the present invention, a part of the main body case having the battery housing portion is provided with a vent hole for ventilating the battery housing portion and the outside of the main body case, and the air permeates through the vent hole. It has a microporous film that does not allow water to pass through.

ケースの内部に充満することはない。Therefore, when one battery is mistakenly connected in the opposite direction and energized in a main body case containing three or more dry batteries, the other battery in the opposite direction is charged. Even if a large amount of gas such as hydrogen or oxygen is generated inside the battery and leaks out of the battery into the main body case, these gases will pass through the pores of the microporous film arranged in a part of the main body case. Since it is discharged outside the case, it does not fill the inside of the main body case.

部に流入して機能を損うことはない。Further, since the microporous film does not allow water to permeate, even when the portable electric lamp is used in water or in rain, water flows from the pores of the microporous film into the main body case and impairs its function. There is no such thing.
