Classified flushing type water-saving system capable of automatically recognizing urine and excrement

Abstract

The invention relates to the field of closestools, and especially relates to a classified flushing type water-saving system capable of automatically recognizing excrement and urine. The system comprises a closestool body, a processor, an inductive sensor A, an electromagnetic valve, an intelligent sound control device, an intelligent terminal communication device, an automatic processing device, a self-pressurization water-saving flushing nozzle, a button and a storage battery. The inductive sensor A, the electromagnetic valve, the intelligent sound control device, the intelligent terminal communication device, the button and the automatic processing device are all in electric signal connection with the processor. The processor comprehensively analyzes a signal of the inductive sensor A, a signal of the inductive sensor B and a signal of the pressure sensor, or sends out a manual instruction or a human body touch instruction through voice, and the electromagnetic valve is driven to discharge water and execute flushing operation within a preset working duration. According to the invention, automatic identification of excrement and urine is realized, classified flushing is realized, intelligence, automation and water saving are high, and through cooperation with the arrangement of large inside and small outside of the flushing holes, the flushing pressure and speed are further increased, water is saved, and the system is more energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the field of toilets, in particular to a flushing type water-saving system for automatically identifying urine and feces and classifying them. Background technique [0002] Automatic flushing is the basic function of smart toilets. Its common implementation forms include infrared or radar human body sensing, human body temperature sensing, turbidity sensor detection, TDS detection sensor, toilet lid pressure sensor detection and so on. [0003] Whether the person is flushing or not is judged by simply infrared or radar human body sensing to detect whether the person leaves the monitoring area. The judgment method is rough and cannot accurately detect whether the person uses the toilet. The use of toilet lid pressure sensors, TDS detection sensors, etc. cannot distinguish male and female urine and urine and their displacement, and thus cannot realize precise control of smart toilet flushing, resulting in non-water-saving toilets...
