Abstract (en)

A drain valve button push button ensemble for dual flush, the ensemble to be mounted on top of a cistern. The direction of the push buttons (311, 312) can be altered independently from a main body (20) in which the buttons (311,312) are arranged. The ensemble further comprises a bracket (11) for being mounted on a drain valve, a connecting sleeve (40) and a compression bar (50). The main body (20) is in threaded connection with the bracket (11), the push buttons are slidably arranged in an accommodating cavity (21) of the main body (20) and can be rotated relative to the main body. The connecting sleeve (4) is arranged in the main body (20) in an axially movable and rotatably locked manner and is connected with the push buttons (311, 312). The compression bar (50) is rotatably locked with the push buttons (311,312) and is in threaded connection with the connecting sleeve (40); and when the push buttons (311, 312) are operated, the connecting sleeve (40) drives the compression bar (50) to move along the axial direction to drive the drain valve to drain water. When the main body (20) is rotated to form a threaded connection between the main body (20) and the bracket (11) to lock a water tank cover, the push buttons (311,312) do not rotate along with the rotation of the main body (20), therefore the direction of the buttons (311,312) is fixed.
