ABSTRACT:
An electromagnetic flush control setup employed in a flush toilet comprising an inducing terminal, an amplifier coupled with a trigger circuit, and an electromagnet setting. The inducing terminal is placed beneath the ringed cover of a flush toilet whereby to induce therein, in accordance with the variation of electrostatic field, a small signal which is then amplified, transduced and rectified to drive a relay so as to charge a capacitor from a DC source. And subsequently with vanishing of the signal, the charged capacitor reversely discharges whereby to initiate a SCR making the electromagnet work and exert up the outlet valve of water box. Upon exhaustion of the capacitor, SCR and electromagnet repose thus accomplishing the flush process.
