 背景技术
采用超低压反渗透膜无泵驱动的净水系统，可以无电直接把自来水转化为直饮水。对于家用净水市场拥有广阔的应用前景。但是头杯水的问题一直困扰着各类渗透膜的应用效果，其中超低压渗透膜尤为突出。
所述头杯水，指的是净水系统停止运行后，滞留在膜壳内的浓缩水，与膜片另一端的直饮水之间通过压力相互渗透，使净水端的直饮水随着时间的增长水质接近浓缩水，因此使滞留在膜壳内的净水变成了不合格的饮用水。
对于超低压反渗透膜，此种情况更加突出。如果一台净水机打开的频率非常频繁，而且持续的时间又比较短，因此造成滞留在膜壳内的水不合格。这种情况下取水越频繁，造成饮用不合格的水越多。所以采用水箱储存直饮水，如果不杜绝系统频繁启动，滞留水箱内的直饮水，短时间就和自来水一样，甚至更差。近年家用净水机市场，各大厂商多推出大通量直流净水机。而消费者实际使用中表现为用量少、使用频繁的特点。因此，导致消费者在实际使用中往往饮用的是头杯水。同时，净水系统频繁启动增加了其电控元器件的损坏几率。
对于小通量的净水机采用储水桶来储存净水，这种净水系统大多采用压力开关来控制净水系统的启动，而压力桶、压力开关及净水龙头是直连的，当打开净水龙头取水时，净水端的压力迅速衰减，造成净水系统启动不可控的。同时，储水桶采用密闭气囊来储水，所述储水桶常由于使用不慎进入空气而造成二次污染，而这种污染很难清除。一是消费者不了解存在这种污染，二是清除这种污染的根本办法就是更换所述储水桶，因而给消费者带来经济损失。
在用户收集浓缩水时，为了避免收集的浓缩水溢出，一般采用一个较大的水桶置于橱柜旁边，既不美观，也非常碍事。可往往还是会有不尽人意的事情发生——溢水。

通过设定所述转轴413运动，迫使所述第一顶杆52的第二活动端沿所述摇臂41表面运动，通过所述摇臂41表面的变化使所述第一顶杆52上下运动，从而达到打开或关闭所述活塞51的目的，提高了活塞51运动的稳定性或灵敏度。
所述长柄412的端部穿过所述复位孔43，用于控制所述长柄412的端部向下运动，使液体从所述第一腔体1流向第二腔体2。
