Document Type and Number:
WIPO Patent Application WO/2023/082338
Kind Code:
A1
Abstract:
A water-bellows-driven water tank flush valve, used for controlling the process of flushing a toilet water tank, the flush valve having only one button and being able to control the amount of water flushed from the water tank in accordance with the depth to which the button is pressed; moreover, the button is extremely light, and only requires 0.1 N of force to be moved when pressed. The flush valve has a water bellows (13), the water bellows (13) is connected to a valve core via a rope lever, and the water bellows (13) is flattened by the pressure of the water in the toilet water tank, thus driving the valve core of the flush valve to open. A control valve (15) is connected to the water bellows (13), and controls the input and output of the water in the water bellows (13). A button (7) controls the action of the control valve (15), and the depth to which the button (7) is pressed controls the degree to which the control valve (15) opens when inputting water into the water bellows (13), thus controlling the amount of water flushed by the water tank.
