[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] Through the designed sealing ring, spring, vent groove and other structures, the safety valve can be well sealed and protected. Under normal circumstances, the sealing ring can be protected on the outside of the vent groove under the push of the spring to play a sealing role. External gas or liquid will not easily enter the interior of the battery. When the air pressure inside the battery increases and pressure relief is required, the gas will lift the sealing ring, causing the sealing ring to rise briefly, thereby relieving pressure. After the pressure relief, the sealing ring falls and continues to perform the sealing function, which is beneficial to the normal use of the battery. BRIEF DESCRIPTION OF THE DRAWINGS
