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.

Abstract: A power-saving controller for toilet flushing includes a passive pyroelectricity detecting device connected to a microcomputer, which is further connected to an active infrared detecting device, and a switch device such that when a user is nearby the toilet in a relatively long distance, the passive detecting pyroelectricity detecting device will respond to generate a first triggering signal to the microcomputer, which in turn generates a second triggering signal to actuate the active infrared detecting device to detect whether a user is using the toilet, if so, then the active infrared detecting device will respond to generate a third triggering signal to feed back to the microcomputer, which in turn enables a timer to count therein, until the user leaves the toilet position, causing the third triggering signal to terminate, which in turn triggers the microcomputer to programmably generate a fourth triggering signal to turn on the switch device, which in turns activates a pumping motor connected thereto to p

Abstract: A faucet includes a sensing/driving assembly having a transmitting/sensing unit electrically connected with a driving device. A driving shaft of the driving device is connected with an actuating device. The actuating device has an actuating stud which depresses a plate having a valve member to control the opening and closing of the faucet.
