Automatic drainage control device of toilet bowl

Abstract

The invention discloses an automatic drainage control device of a toilet bowl, wherein a first hydraulic cylinder, a second hydraulic cylinder, a first piston rod and a second piston rod are arranged in a water tank thereof; a transmission mechanism being capable of driving a valve cover plate to move up and down is arranged between the two piston rods and the valve cover plate; a first running water pipe, a first water exit, a second running water pipe and a second water exit are also arranged; the back end of the first water exit is communicated with the cavity of the first hydraulic cylinder; the back end of the second water exit is communicated with the cavity of the second hydraulic cylinder; the water outlet of the first running water pipe is also covered by a first rubber cushion; the water outlet of the second running water pipe is also covered by a second rubber cushion; a first pressure chamber is formed above the first rubber cushion; a second pressure chamber is formed above the second rubber cushion; the cover board is also coaxially and fixedly connected with a shifting block; a three-pronged transmission block is rotatablely arranged beside the shifting block; and a first pressure relief valve and a second pressure relief valve are arranged beside the three-pronged transmission block. The automatic drainage control device can realize automatic flush without pressing a push button.

Description

technical field [0001] The invention belongs to the technical field of sanitary ware, and in particular relates to an automatic drainage control device for a toilet. Background technique [0002] At present, most of the drains of toilets adopt manual buttons, which need to be pressed with fingers to flush water, which is inconvenient and unhygienic. Especially in public places, some people forget or do not want to press the button to flush water after using, which makes the sanitary condition of toilets in public places very poor, which brings inconvenience to users and managers. For this reason, some toilets adopt electromagnetic induction electric drainage control devices to realize automatic flushing, but the cost is high, and the electromagnetic induction devices and electric devices are easily damaged or insensitive due to being in a humid environment. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and pr...
