Method and arrangement for controlling flush water volume

摘要

A flush water control arrangement includes a water control pusher alignedly extended towards a flushing shaft, and an automated actuation unit which includes a motorized unit and an automated plunger arm movably extended towards the water control pusher. When the motorized unit is activated in responsive to a presence of a user, the automated plunger arm is driven by the motorized unit to move the water control pusher so as to actuate the flushing shaft between the first and second positions for complete a flushing operation. The water control pusher is actuated to push at the second position of the flushing shaft to complete the flushing operation with a relatively high volume of water. The water control pusher is actuated to push at the first position of the flushing shaft to complete the flushing operation with a relatively low volume of water.

主权项

1. A flush system, comprising:
a valve body having a water inlet and a water outlet; a valve seat supported in said valve body between said water inlet and said water outlet, wherein said valve seat is adapted to move between a normal idle position that water is blocked to flow from said water inlet to said water outlet and a flushing position that said water is allowed to flow from said water inlet to said water outlet so as to complete a flushing operation; a flushing shaft extended from said valve seat to move said valve seat between said idle position and said flushing position, wherein said flushing shaft defines a first position and a second position; a flush water control arrangement, which comprises: a water control pusher alignedly extended towards said flushing shaft; and an automated actuation unit which comprises a motorized unit and an automated plunger arm movably extended towards said water control pusher, wherein when said motorized unit is activated in responsive to a presence of a user, said automated plunger arm is driven by said motorized unit to move said water control pusher so as to actuate said flushing shaft between said first and second positions for complete a flushing operation, wherein said water control pusher is actuated to push at said second position of said flushing shaft to complete said flushing operation with a relatively high volume of water, wherein said water control pusher is actuated to push at said first position of said flushing shaft to complete said flushing operation with a relatively low volume of water.
