隔膜水泵是一种市场上广泛应用于日常生活中的工业产品，如咖啡机，饮水机，净水机，地板/地毯清洗机等，其种类和样式繁多，因为它的体型小，性能优异，成本低，其逐渐有取代电磁水泵的倾向。
不过，当前市场上此类微型隔膜水泵都因为其结构特点，存在一个较的不足：正向止漏能力较差，在有些应用中对正向止漏要求较高时，需要与单向阀配套使用才能满足止漏的要求，这样在成本上的优势就又降低了；而且单向阀的使用也增加了组装成本。
实用新型内容
为了克服现有技术的不足，本实用新型提供一种微型隔膜水泵，该微型隔膜水泵具有止漏功能，大大降低了水泵与单向阀两种组件所占用的空间，降低了组装的成本。

在上述的结构中，所述的驱动装置包括曲柄、中心轴、连杆、膜片、进口阀以 及出口阀；
所述的曲柄与马达的输出端相连接，所述中心轴的一端固定在曲柄上，中心轴的另一端与所述的连杆相连接；所述膜片的顶部固定在膜片支架上，膜片的底部穿过于连杆，连接在底座上；
所述水泵本体的内腔包括膜片与阀支架之间形成的第一密封腔以及阀支架与端盖之间形成的第二密封腔；所述的阀支架上设置有连通第一密封腔和进水管的通孔，所述的进口阀安装在该通孔内；所述的阀支架上还设置有连通第一密封腔和第二密封腔的通孔，所述的出口阀安装在该通孔内。
在上述的结构中，所述的端盖、阀支架以及膜片支架通过螺钉依次固定安装在底座上。
