Abstract:
1. A method of installing a driving mechanism into an existing flush apparatus which comprises a valve body having an operation opening, a water valve normally being retained at a sealed position, and a manual operation unit to move said water valve from said sealed position to an unsealed position, wherein the installing method comprises the steps of: (a) removing said operation unit from said valve body at said operation opening thereof; (b) coupling an actuation housing, having an actuation channel, with said valve body at said operation opening, wherein a motorized unit, which is a DC electric motor, is supported in said actuation housing; and (c) aligning an automated plunger arm with a diaphragm member of said water valve at a position that said automated plunger is transversely supported along said actuation channel and is driven by said motorized unit by the steps of: (c.1) activating said motorized unit in responsive to a presence of a user for generating a mechanically rotational power, wherein said motorized unit has an output that said rotational power is generated at said output of said motorized unit; (c.2) transmitting said rotational power of said motorized unit to a transverse force through a transmission unit; and (c.3) driving said automated plunger arm by said transverse force to move forward for moving said water valve from said sealed position to said unsealed position while said diaphragm member is then moved back to said sealed position, wherein said automated plunger arm is driven to move by a gear set and a driving arm of said transmission unit, wherein said gear set is operatively coupled with said output of said motorized unit, wherein said driving arm has one end operatively coupled with said gear unit and an opposed end operatively coupled with said automated plunger arm to transmit said rotational power to said transverse force, so as to drive said automated plunger arm to laterally move in a reciprocating manner; and (d) laterally moving said automated plunger arm back to its original position by said driving arm of said transmission unit via said rotational power of said motorized unit.
