ABSTRACT:
A gas safety detector having a self-detection function includes a base board, an electromagnet, a gas device, a magnetically attractive plate, and a sensor. Thus, the gas safety detector has a self-detection function. In addition, when the electromagnet stops operating due to a malfunction or electric shutoff, the magnetically attractive plate is released to release the hook portion which releases the nozzle of the gas device, so that the retractable nozzle of the gas device is returned to the original position immediately so as to stop flow of the gas, thereby preventing the gas from leaking outward so as to provide a protective effect.
