水是一种重要的自然资源,但是浪费现象时常发生,抽水马桶的使用即是一例。普通抽水马桶主要存在两个缺陷:一是多采用橡皮塞密封出水孔,而橡皮塞容易老化变形,造成马桶漏水;二是无法控制排水量。针对上述缺点,我设计了一种新型节水抽水马桶(图1)。 Water is an important natural resource, but wastefulness often occurs. The use of flush toilets is an example. There are two main drawbacks of ordinary toilets: First, the use of rubber plugs to seal the outlet hole, and the rubber plug is easy to aging deformation, resulting in toilet leakage; second, can not control the displacement. In response to these shortcomings, I designed a new type of water-saving toilet (Figure 1).
