Abstract
A flush controller for a toilet bowl which can be readily added to the water reservoir of the currently used toilet bowl, includes a detecting device for detecting that a user has approached the toilet bowl to within a predetermined effective distance, that the user has remained within the predetermined effective distance for a first predetermined period of time, and that the user has left the predetermined effective distance. The flush controller also includes motor, having an output rotation shaft, a cap control coupled to the output rotation shaft of the motor for being driven by the motor, the cap control adapted to be connected to an outlet cap within the water reservoir of the toilet bowl, and a control device coupled to the detecting device and the motor, whereby when the detecting device detects that the user has approached the toilet bowl and remained within the predetermined effective distance for the first predetermined period of time, and that the user has left the predetermined effective distance thereafter, the control actuates the motor to rotate so as to drive the cap control to open-up the outlet cap, starting the water in the water reservoir to flush. The control …
