Abstract
The utility model relates to a squatting pan flushing control device, in particular to a squatting pan flushing control device adopting an ultrasonic sensor, which is characterized in that a circuit of the ultrasonic sensor consists of the ultrasonic sensor, an ultrasonic drive module and a gate circuit. An I/O input end of a single-chip microcomputer is connected with an output end of the circuit of the ultrasonic sensor. The single-chip microcomputer differentiates stool flushing and urination flushing according to time parameters of reflected signals of the circuit of the ultrasonic sensor. An I/O output end of the single-chip microcomputer is connected with an electromagnetical valve control circuit. The squatting pan flushing control device adopting an ultrasonic sensor has the advantages that ultrasonic signals are transmitted and received by the circuit of the ultrasonic sensor with high accuracy. The single-chip microcomputer receives the signals of the ultrasonic sensor to effectively control the squatting pan to differentiate the stool flushing from the urination flushing. The squatting pan flushing control device adopting an ultrasonic sensor has excellent water-saving effect, being applicable to different service environments and widely applied to automatic flushing control for the squatting pan in an intelligent public lavatory management system.
