JPS5919332Y2 - Exhaust plug for storage battery - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to an improvement of an exhaust plug for a storage battery.

To explain this with reference to the drawings, reference numeral 1 denotes an exhaust plug main body, and a bottom plate 3 having a partition wall 2 set upwardly is integrally formed in an internal cavity.

4 is a notch in the upper part of the partition wall 2; 5 is a groove 6 in the notch 4;
7 is a threaded part for attaching the lower part of the exhaust plug main body 1 to the liquid injection port 9 of the storage battery lid 8, 10 is a rubber gasket, and A and B are A vacant space divided inside the exhaust plug body 1,
Reference numeral 11 indicates a gas introduction hole provided in the bottom plate 3 for introducing gas generated in the storage battery into the empty chamber portion A, and 12 indicates a gas inlet hole provided in the bottom plate 3 for discharging the gas within the empty chamber portion B from the exhaust plug main body 1. This is an L-shaped exhaust passage formed in the bottom plate 3 under the empty chambers B and A.

When this exhaust plug is attached to the storage battery, the gas in the storage battery flows from the gas introduction hole 11 through the empty chamber A, the microporous filter 5, the empty chamber B, the exhaust passage 12, and then from the exhaust hole 13 as shown by the arrow. It is discharged outside the exhaust plug main body 1.

Reference numeral 14 denotes a lid that is removably covered with the exhaust plug main body 1.

Since the exhaust plug of the present invention has the above-described structure, even if the gas exhausted outside the exhaust plug ignites for whatever reason, the flame is blocked by the microporous filter 5, so there is no possibility that the gas will be inside the storage battery. There is no possibility of an explosion if water enters the storage battery, and even if the exhaust plug is splashed with water when cleaning the storage battery, the exhaust passage 12 is
Because it is shaped like a letter, there is no risk of it entering the exhaust plug body 1, and the microporous filter 5 is
Because it is housed inside the chamber, there is no dust attached to it, and because it is installed vertically in the notch 4 at the top of the partition wall 2, the acid mist is transferred to the microporous filter on the side of the empty chamber A. Even if it adheres to the surface of the exhaust plug body 1, it drips downward from the surface so that it does not infiltrate into the empty chamber B side or leak outside.
Since it is attached, it is possible to easily clean the inside of the exhaust plug body and replace the microporous filter, which has great practical value.

Claims (1)

[Scope of utility model registration request] Inside the exhaust plug body with a removable lid, a partition wall having a notch in the upper part is planted upward from the bottom plate to form a divided chamber, and a small space is provided in the notch to fill this part. In addition to installing a porous filter, a gas introduction hole for introducing the gas in the storage battery is formed in the bottom plate in one of the divided chambers, and an L-shaped exhaust passage leading to the outside of the exhaust plug body is formed in the bottom plate in the other. An exhaust plug for a storage battery, which is formed into a penetrating shape.
