Motorized automate/manual push button system

摘要

A driving mechanism of a flush apparatus includes a motorized unit supported by a valve body, a plunger arm driven by the motorized unit for operating the valve body between a sealed position to an unsealed position, and a timer module operatively linked to the motorized unit to set a flush interval for enabling the flushing operation to be completed once every flush interval. The driving mechanism converts the flush apparatus into water efficient fixture by controlling the amount of daily flushes for ultimate water efficiency.

1. A driving mechanism for a flush apparatus which comprises a valve body having a water inlet and a water outlet, wherein said driving mechanism comprises:
a motorized unit adapted for being supported by said valve body; and a plunger arm driven by said motorized unit for operating said valve body from a sealed position that water is blocked to flow from said water inlet to said water outlet, to an unsealed position that water is guided to flow from said water inlet to said water outlet to complete a flushing operation of said flush apparatus; a timer module operatively linked to said motorized unit to set a flush interval for enabling said flushing operation to be completed once every flush interval; and a manual actuation unit which comprises a manual actuator being supported at a position parallel to said plunger arm, wherein said manual actuator is manually pushed to override said timer module and to bypass said motorized unit for operating said valve body from said sealed position to unsealed position, wherein said plunger arm has a tubular structure that said manual actuator is coaxially and slidably received at said plunger arm, such that when said manual actuator is manually actuated to override said timer module, said plunger arm is driven for operating said valve body from said sealed position to unsealed position.
