Resumen de: EP4717953A1

A drain valve (13), a battery (100), and an electric device are provided, pertaining to the field of battery technology. The drain valve includes a valve body (131), a valve core (132), a gas-generating substance (133), and a check member (135). The valve body has a liquid inlet (1311) and a liquid outlet (1312). The valve core movably fits with the valve body to close the liquid outlet. The gas-generating substance is at least partially disposed within the valve body, and the gas-generating substance is configured to react with liquid water to generate a gas so as to push the valve core to open the liquid outlet. The check member is configured to allow the liquid water to enter the valve body from the liquid inlet and restrict gas from flowing out of the valve body through the liquid inlet. The gas-generating substance reacts with the liquid water to produce the gas, and the check member restricts the gas from flowing out of the valve body through the liquid inlet. As the gas increases, the pressure inside the valve body gradually increases, thereby pushing the valve core to move and open the liquid outlet, and allowing the liquid water to be discharged from the battery through the liquid outlet. This reduces the risk of leaked liquid water inside the battery causing a short circuit in a battery cell, which otherwise leads to an increase in the temperature of the battery and thus causes a fire in the battery, thereby improving the reliability of the battery during use.
