许多家庭把储水容器放在楼顶,水晒热后可用于洗澡。本装置水满时报知信号,使用几年来效果很好。简单、可靠、省电,两节5号电池可用半年以上。电路原理如附图,A、B两点接通时,T1导通,T2、T3产生自激振荡,扬声器发出报警声音,A、B两点是一个插座,连接插头的两条导线引向储水容器,并固定在容器顶部。报满时,可以拔下插头,以消除报警声响。
Many families put water storage containers on the roof, and the water can be used for bathing after it is hot. When the device is full of water signal, the use of good effect over the past few years. Simple, reliable, energy-saving, two batteries available on the 5th half a year or more. Circuit diagram shown in Figure, A, B two connected, T1 conduction, T2, T3 self-excited oscillation, the speaker sounded the alarm sound, A, B is a two-point socket, plug the two leads lead storage Water container, and fixed to the top of the container. When full, you can unplug the plug to eliminate the alarm sound.
