The battery mounting inner housing 5 is also provided with a vent line 17. When the housing 10 is mounted on the battery mounting inner housing 5, the vent lines 17 on both sides are connected. The vent line 17 is connected to the battery chamber 9 in the battery mounting inner housing 5. A spring 15 is provided at one end of the valve stem 13. When the battery in the battery chamber 9 catches fire and smokes, the internal pressure increases, and the marbles are moved through the vent line 17. 16 is pushed back, and the valve plate 14 pops up, so that fire and smoke can be exhausted.
