水冲式厕所,由于具有清洁卫生的优点,得到了广泛的应用。这种厕所原来多用自动冲水器,后来我们根据虹吸原理,自制了既简单又经济的自动冲水器。用直径50毫米水管制成如右图所示的虹吸管,将长段攻丝。蓄水箱底中心处留出略大于水管外径的孔洞,将虹吸管长段从箱 Water flush toilets have been widely used due to their clean and hygienic advantages. This type of toilet used more automatic flushers. Later, based on the siphon principle, we made a simple and economical automatic flusher. Using a 50 mm diameter water pipe, make a siphon tube as shown on the right and tap the long section. A hole slightly larger than the outer diameter of the water pipe is left at the center of the bottom of the water storage tank and the long section of the siphon pipe is removed from the tank.
