一种新型节水自动冲厕装置的设计

Design of a new type of automatic water-saving toilet-flushing device

传统的红外感应冲厕装置不仅节水能力较差而且结构复杂成本高。基于力敏传感器、测量放大电路和定时开关控制的新型节水自动冲厕装置,选择与红外感应冲厕装置不同的感应对象,从而实现自动和即时冲厕,感应灵敏度高;该装置电路设计和控制都比较简单,因而成本低;由于采用循环冲水机制,不仅减小失误率而且更加节水。实践表明,这种新型自动冲厕装置不论在成本上还是在环保和人性化方面都比传统红外冲厕装置更具优势。

The traditional infrared sensors toilet-flushing Device, not only have poor water-saving ability and complex structure, but also requires higher costs. A new type of automatic toilet-flushing device based on force sensor, measuring amplifying circuit and timer switch control, choose different Sensing object,therefore which can flush toilet automatically and timely,with high sensitivity. This device has simple circuit, and easy control, therefore its cost is low .In addition, due to flushing cyclically, not only it can reduce the error rate,but also save more water. Practice shows that this new type of toilet- flushing device has more advantages than traditional infrared sensors toilet-flushing device, whether in the sight of cost and the environmental protection or of humanization.
