本实施例中，第一进水腔201的上端设有第一开口401，止水单元包括止水膜片501、固定盖502和驱动机构，止水膜片501安装于固定盖502上，止水膜片501的四周抵接于第一开口401的四周边缘；驱动机构设置于阀体10上，并控制止水膜片501的中部开启或关闭第二开口402。
阀体10内还设有背压腔105，该背压腔105和第一进水腔201通过止水膜片501隔开，止水膜片501上设有连通背压腔105和第一进水腔201的细水孔，固定盖502上设有穿过所述细水孔的细水柱。背压腔105设有泄压孔104，驱动机构控制该泄压孔104开启与否，当泄压孔104处于开启状态时，止水膜片501开启第二开口402；当泄压孔104处于关闭状态时，止水膜片501关闭第二开口402。背压腔105内设置向下抵住止水膜片501的弹性件(图中未体现)。本实施例中，驱动机构通过固定螺丝80连接于阀体10，驱动机构为电磁阀头601或机械开关701。阀体10包括上盖和阀壳，上盖固定连接在阀壳上,驱动机构即通过固定螺丝80连接在上盖上。
本实施例中，电磁阀头601包括固定支架-I 6011、线圈组件6012、动铁芯6013和复位弹簧-I6014，线圈组件6012通过固定支架-I固定在阀体10外。动铁芯6013活动设置于线圈组件6012中，且动铁芯6013的一端设置用于启闭泄压孔104的堵头-I 6015，复位弹簧-I 6014套装在动铁芯6013外，用于复位堵头-I 6015。
机械开关701包括固定支架-II 7011、压杆7012、传动杆7013和复位弹簧-II7014，压杆7012与传动杆7013一端铰接，用于控制传动杆7013移动；固定支架-II 7011具有内腔，传动杆7013的另一端置于内腔且通过连接块7015连接用于启闭泄压孔104的堵头-II 7016，复位弹簧-II 7014套装在连接块7015外，用于复位堵头-II 7016。
实施例一
当驱动机构为电磁阀头601时，其工作过程如下：
初始默认状态下，即电磁阀6011未通电时，在复位弹簧-I 6014的作用下，堵头-I 6015堵住泄压孔40，背压腔105压力增大，使得止水膜片501压封住第二开口402，进水口101和第一出水口102之间的第一水路301未连通，外部水源从进水口101进入，此时，水只能进入第一进水腔201内，然后从第二出水口103排出；电磁阀6011通电时，线圈组件6012吸附动铁芯6013向上移动，进而堵头-I 6015向上移动，从而打开泄压孔104，背压腔105压力下降，使得止水膜片501上移，第二开口402打开，使进入第一进水腔201的水流可流入第二进水腔202内，从而从第一出水口102排出。此时，第一出水口102和第二出水口103同时出水，实现从二通进水阀切换为三通进水阀，阀体10起三通连接通路功能。
实施例二
当驱动机构为机械开关701时，其水路切换原理与实施例一相同，仅驱动堵头的方式存在不同，其工作过程如下：
默认状态下，压杆7012未受外力按压，在复位弹簧-II 7014作用下，堵头-II7016堵住泄压孔104，背压腔105压力增大，使得止水膜片501压封住第二开口402，进水口101和第一出水口102之间的第一水路301未连通，外部水源从进水口101进入，此时，只能进入第一进水腔201内，然后从第二出水口103排出；当压杆7012受外力按压，传动杆7013抬起，从而令堵头-II 7016打开泄压孔104，背压腔压力下降，第二开口402打开，使进入第一进水腔201的水流可流入第二进水腔202内，从而从第一出水口102排出。此时，第一出水口102和第二出水口103同时出水，实现从二通进水阀切换为三通进水阀，阀体10起三通连接通路功能。
本发明的一种智能马桶，包括马桶冲刷系统和智能马桶盖，还包括如上所述的多路进水阀，所述第一出水口和第二出水口中的一个连接所述马桶冲刷系统的进水管路，所述第一出水口和第二出水口中的另一个连通所述智能马桶盖上设置的进水管路。
