Zusammenfassung:A drain device includes a tube set, a transmission, a stopper and a driver. The transmission is disposed in a main tube and an isolating inner tube, and extended from the front end of the isolating inner tube to the front end of the main tube. The stopper is mounted to a front end of the transmission, and adapted to close or open a water feeding inlet. The driver is disposed in the isolating inner tube, and mechanically connected to the transmission, whereby after the driver receives an electronic control signal, the driver drives the stopper to move downward or upward via the transmission, and there is a sealing effect or a gap between the stopper and the annular plate.
