Title:
FASTENING DEVICE FOR INNER CORE CYLINDER OF FLUSH VALVE
Document Type and Number:
WIPO Patent Application WO/2017/201642
Kind Code:
A1
Abstract:
A fastening device for an inner core cylinder of a flush valve, the device comprising a main body (1), an inner core cylinder (2), a lifting member (3), a half flush float (41), a half flush adjustment lever (51), a half flush support frame (52), a full flush float (42), and a lever locking mechanism. When the water level is rising, the full flush float (42) moves toward the inner core cylinder (2), and a full flush stopper (421) moves closer to the inner core cylinder (2); at the same time, the half flush float (41) lifts and pulls the half flush adjustment lever (51) to move upward, the half flush adjustment lever (51) drives the half flush support frame (52) to rotate closer to the inner core cylinder (2), a half flush stopper (521) moves closer to the inner core cylinder (2), and a pushing portion of the half flush adjustment lever (51) exerts a force on the lever locking mechanism to achieve interlocking. When the water level is lowering, the full flush float (42) moves away from the inner core cylinder (2), and the full flush stopper (421) moves away from the inner core cylinder (2); at the same time, the half flush float (41) lowers and drives the half flush adjustment lever (51) to move downward, the half flush adjustment lever (51) drives the half flush support frame (52) to rotate away from the inner core cylinder (2), the half flush stopper (521) moves away from the inner core cylinder (2), and a pressing portion of the half flush adjustment lever (51) exerts a force on the lever locking mechanism to release interlocking. The device enables precise flushing despite a long press on a flush button, thus saving water resources.
