自动延时供水虹吸冲水节水技术的研究

自动延时供水虹吸冲水节水技术中人体感应器部分,采用了热释电红外探测技术,避免了环境光线的影响,保证了只有在有人进入有效区域内时才准确地发出控制上水信号,达到了无人时自动停止上水,有人时自动上水的目的。其上水有一个延时过程,延时时间要略高于水箱一次上满水的时间,而只有上满水整个系统才能形成虹吸现象,形成一次有效的冲洗。

The Research into the Water-saving Technology of Autonomous Delayed Water Supplying and Siphon Flush

In the Water-saving Technology of Autonomous Delayed Water Supplying and Siphon Flush,the body sensor adopts the pyroelectric infrared detection technology and avoids the influence of lights.It guarantees that only when human body moves into the effective area can the water supply signal be sent.In this way,it reaches the goal of stopping water supply without human in range and autonomously starting the water supply with human in range.The water supply has a delay which is a little longer the time span of filling the tank.Only when the whole system is filled can there be siphon and an effective flush is formed.
