1. A flush apparatus for a flush system, comprising:

  • a valve body having a water inlet for connecting to a water source to guide water to flow to said water inlet at a water-in direction, and a water outlet for connecting to the flush system;

    a sensor, having a detecting range, for detecting a presence of a user of the flush system within said detecting range, wherein said sensor generates a first actuation signal when said sensor detects the presence of the user and generates a second actuation signal when said sensor detects the user being out of said detecting range;

    a power generator, which is activated by said sensor; and

    an actuation control, which comprises;

    a cartridge valve, which is detachably coupled to said power generator, comprising a cartridge housing stationary supported in said valve body at a position that a valve inlet of said cartridge housing is located at said water inlet and a valve outlet of said cartridge housing is located at said water outlet,a control disc unit which is supported in said cartridge housing at said valve inlet thereof and is orientated transversely to the water-in direction for resisting water pressure from said water source, wherein, in response to said sensor, said control disc unit is able to be driven to move by said power generator between a closed position, via said second actuation signal, to close said valve inlet for blocking the water to pass through said valve inlet, and an opened position, via said first actuation signal, to open up said valve inlet for allowing the water passing to said water outlet through said valve outlet so as to complete a flushing cycle of the flush system; and

    a manual flush actuator comprising a manual switch coupled at said cartridge valve to manually move said control disc unit between said closed position and said opened position, wherein said cartridge housing has a tubular surrounding wall defining an open end as said valve inlet and said valve outlet is formed at said surrounding wall of said cartridge housing to align with said water outlet, wherein said control disc unit comprises a sealing disc rotatably coupled within said surrounding wall at said open end thereof to selectively close said valve inlet, and a control shaft extended from said sealing disc through a closed end of said surrounding wall to operatively couple with said power generator so as to drive said sealing disc to rotate between said closed position and said opened position, wherein said manual switch coupled at said control shaft to manually drive said sealing disc to rotate between said closed position and said opened position, wherein said manual flush actuator further comprises a resilient element coupled at said manual switch to move back said manual switch after said manual switch is actuated.
