Double-acting stepless drainage of flush toilet

Abstract

The invention discloses a double-acting stepless drainage of a flush toilet. A central pressure lever support (25) is arranged in the inner hole of a water control base (13); a central pressure lever (23) passes through the center of the central pressure lever support (25); a cylindrical cam (24) and a hand wheel (20) are arranged above the central pressure lever (23); a hollow central button cap (21) is arranged in the middle hole of the hand wheel (20); the central button cap (21) is connected at the top end of the central pressure lever (23); the lower end of the central pressure lever (23) is in contact with a drain valve assembly (10); a cam pressure lever (15) is arranged in the small hole of the lower end of the water control base (13); the cam pressure lever (15) is connected with a length adjusting lever (11); and the length adjusting lever (11) is in contact with the drain valve assembly (10). The invention solves problem that the traditional flush toilet can use water only in one gear or two gears and arbitrarily discharges the water of the flush toilet between 0 to n according to actual requirements; moreover, when the flush toilet needs flushing with large amount of water, n liters of water is discharged instantaneously.

Description

technical field [0001] The invention relates to a drainage device, in particular to a double-action stepless drainage device for a flush toilet, which is used for realizing stepless drainage according to the water consumption. Background technique [0002] Water conservation is a worldwide resource conservation issue, and flushing water for flush toilets accounts for about one-third of all household water consumption. At present, whether it is a siphon type or a direct flush type, the ordinary flush toilets for households can only realize the flushing of two gears of large and small displacements, which can achieve water saving effect to a certain extent compared with traditional flush toilets, but for smaller water consumption The need for stepless flushing of any amount of water between 0-n liters cannot be achieved. Contents of the invention [0003] The object of the present invention is to provide a double-acting stepless drainage device for flush toilets, which over...
