【考案の詳細な説明】
本考案は蓄電池液口栓の改良に関するものであ
る。[Detailed Description of the Invention] The present invention relates to an improvement of a storage battery liquid plug.
従来自動車用蓄電池の液口栓は、充電時に発生

い。 Conventionally, various types of liquid spout plugs for automotive storage batteries have been proposed that have a splash-proof structure inside the liquid spout plug in order to prevent sulfuric acid mist from scattering together with the gas generated during charging. No consideration has been given to explosion protection or filter clogging.
本考案は上記の点に鑑み、液口栓本体の上部を

した蓄電池液口栓である。 In view of the above points, the present invention separates the upper part of the liquid outlet plug body into an upper chamber and a lower chamber by a substantially horizontal donut-shaped explosion-proof filter, and a gas passage passing through the center of the explosion-proof filter. This is a battery liquid spout plug in which an upper chamber and a lower opening of a liquid spout body communicate with each other, and the periphery of the lower chamber is opened to the outside.

In a storage battery equipped with the liquid port plug 1, oxygen-hydrogen gas generated from the storage battery enters the upper part through the gas inlet holes 4, 4' provided in the splash-proof plate 3, and further passes through the gas passage 5 to the upper chamber 6. leading to. Further, gas passing through the pores of the explosion-proof filter 7 made of alumina, synthetic resin, etc. is discharged to the outside through the lower chamber 8.

９はパツキングである。 Further, in the present invention, even if ignition occurs due to an external source, the explosion-proof filter 7 can prevent the interior of the liquid port plug 1 from igniting and exploding. Further, when the size of the gap in the lower chamber 8 is limited to a range of 1 to 5 mm, a small explosion can be caused in the lower chamber 8 and the self-extinguishing function by the blast wave can be maintained. Note that 9 is punching.

値甚だ大なるものである。 As mentioned above, the present invention can maintain a safe explosion-proof function with a relatively large-diameter explosion-proof filter even in small liquid plugs such as automobile storage batteries, and prevents clogging due to dust etc. Since there is no water attached to the explosion-proof filter when washing with water, the explosion-proof filter will not freeze.Furthermore, the explosion-proof filter is formed in a donut shape, and the lower chamber is open to the surrounding area, so that the gas is dispersed over a wide area. It has great practical value, as it can uniformly dilute the gas concentration and prevent the risk of ignition, and it is easy to work because there is no directionality when configuring the liquid port plug.
