Abstract
A flushing device for toilets has a supporting assembly and a driving mechanism. The supporting assembly supports the driving mechanism in a tank of a toilet by use of adjustable beams which span the tank and a bridge plate which connects to the beams. The driving mechanism has an infrared sensor placed on a wall behind the tank, a motor contained in a waterproof housing and a disk connected to the motor by a shaft. The disk engages with a conventional flushing assembly sited in the tank. The sensor actuates the motor to rotate when the sensor detects the presence and exit of a user, thereby flushing the toilet.
