As preferably, width and the depth ratio of described stopper slot are less than or equal to 0.985.The allowable angle of inclination that inner tube is radially wobbled and produce can not exceed 10 °, can further reduce the impaired possibility of liquid injecting mouth.
As preferably, the upper surface of described safety valve is lower than the upper surface of described cover plate.In use procedure, can not produce the phenomenon that collides safety valve and cause inner tube to be damaged, fail safe is good.
As preferably, the upper surface of described cover plate is provided with groove, and the upper end of described outer tube and the diapire of described groove link together.Can improve the structural strength of cover plate.
As preferably, in described inner tube, be also provided with condensation net.While running into condensation net when the gas that the contains water vapour outflow in storage battery, water vapour is condensed into water and can discharge storage battery through safety valve.Realize second goal of the invention.
As preferably, described condensation net is positioned at the top of described filter.Can reduce the anti-acid corrosion requirement of condensation net, condensed water can play the effect of the residual acid on air filter piece being rinsed back to battery fluid, can keep better the concentration of acid in battery fluid constant.
As preferably, the lower surface of described condensation net is sphere or the conical surface upwards caving in.Can increase the contact-making surface of condensation net with steam, more abundant to the condensation of steam; Can also play the effect that condensed water is fallen from the edge of condensation net, prevent from that condensed water from falling fully to contact and by double evaporation-cooling, condensation efficiency is high with the gas rising.
As preferably, the upper surface of described air filter piece is to the sphere of lower recess or the conical surface, and the projection vertically downward of the lower surface of described condensation net is positioned at the upper surface of described filter.Can improve the cleaning performance of condensed water to air filter piece.
The utlity model has following advantage: liquid injecting mouth has been designed to inner and outer tubes and has formed, outer tube upper end is connected in cover plate, use middle external tube to be not easy to be collided, only can collide inner tube, and stopper slot has limited the scope of inner tube bending, thereby it is damaged that liquid injecting mouth is not easy; Fluid injection and exhaust are all undertaken by liquid injecting mouth, can reduce the pore quantity on cover plate, thereby play the effect of the structural strength that improves cover plate; By gas leakage sheet is set in liquid injecting mouth, can prevent that acid mist from overflowing.
