Automatic flush actuation apparatus

An automatic flush actuation apparatus for a flushing system which comprises a valve body having a water inlet, a water outlet, and a water chamber communicating between said water inlet and said water outlet, and a valve seat, having a flush channel, normally sealed with said water chamber for retaining a predetermined water pressure within said water chamber so as to block water flowing from said water inlet to said water outlet, wherein said automatic flush actuation apparatus comprises:

• a valve member adapted for being disposed at said valve seat to control said water flowing from said water inlet to said water outlet;
• and
• a sensor-operated powering assembly, comprising:
• a power source;
• a power generator;
• a CPU electrically connected with said power source and said power generator for sensing a presence of a user of said flushing system, so as to activate said power generator;
• a relief valve provided at said valve member for controlling said water flowing from said water inlet to said water outlet through said water chamber, wherein said relief valve has a water passage extended along said valve member to communicate said water chamber with said water outlet and comprises a valve stopper and a retaining element normally retaining said valve stopper on said valve member to close said water passage for controlling a water flowing from said water inlet to said water outlet;
• and
• an actuator driven by said power generator to move said relief valve between an auto-operated closed position and an auto-operated opened position, wherein at said auto-operated closed position, said valve stopper is sealedly retained to close said water passage for blocking said water passing to said water outlet, and at said auto-operated opened position, said valve stopper is moved to an opened position by said actuator for releasing said water pressure within said water chamber to allow said water passing to said water outlet, wherein said retaining element is a resilient element coupling with said valve stopper so as to normally retain said valve stopper at said auto-operated closed position, wherein said valve stopper, having a ball-shape, sits on said valve member at an opening of said water passage to normally close said water passage for blocking said water passing to said water outlet, wherein said resilient element is a compression spring disposed within said water passage for applying an urging force against said valve stopper so as to normally pull said valve stopper to close an opening of said water passage, wherein said resilient element has a biasing end is coupled with said valve stopper and an opposed affixing end coupled with a bottom end of said water passage for applying a pulling force against said valve stopper.
