针对现在很多住户仍在使用的旧式厕所便池水箱在结构上存在着浪费水的问题,经过研究和实验,只在水箱、吸水管管口加装一个木塞就能成为一种节水型的便池水箱。旧式厕所便池水箱结构如图1。其工作原理是:用水冲洗便池时,拉动拉绳1,经杠杆2带动拉杆3让回位弹簧4压缩,这时固定在杠杆下端的密封胶塞5就离开了其封闭口6,水箱中的水就先从封闭口流入冲水管7去冲洗便池,此时虽松开了拉绳,弹簧将胶塞四位堵死封闭口,但冲水管中已形成真空,水箱内的水在大气
In view of the problem of wasting water on the structure of the old-fashioned toilet bowls that are still used by many households, after research and experimentation, only adding a cork to the tanks and suction pipe nozzles will become a water-saving type. The toilet tank. The old type toilet toilet tank structure is shown in Figure 1. Its working principle is: When flushing the urinal with water, the pulling cord 1 is pulled, and the lever 3 is driven by the lever 2 to make the return spring 4 compress. At this time, the sealing rubber plug 5 fixed at the lower end of the lever leaves its closing port 6 and the water tank The water first flows from the closed mouth into the flush pipe 7 to flush the bowl. At this time, although the pull rope is loosened, the spring seals the rubber plug and closes it. However, a vacuum is already formed in the flush pipe, and the water in the water tank is in the atmosphere.
