[0022] More specifically, in this embodiment, whether the electromagnet 4 is connected through the connector 41, so that the static iron core 6 attracts the moving iron core 9 to approach, the moving iron core 9 drives the blocking column 12 and the lower blocking plate 13 to move upward, until the lower blocking plate 13 is attached to the lower surface of the sealing sleeve 11, together with the blocking column 12 and the sealing sleeve 15, it forms a vertical tube body 2, providing a double sealing effect when the electromagnetic valve clears the gas, and the air inlet 31 delivers oxygen-generating gas to the air outlet 32, or disconnects the electromagnet 4, so that the moving iron core 9 is rebounded by the spring 20.
