 本发明的实施方式
为了进一步解释本发明的技术方案，下面通过具体实施例来对本发明进行详细阐述。
本发明为一种排水控制装置，包括主体1、上盖2、下盖3、泄压盖4、膜片5和复位件20；主体1设置有进水槽11、排水槽12和过水槽13，进水槽11、排水槽12均连通至过水槽13；上盖2与排水槽12围成排水腔a，排水腔a设置有至少一个排水端口b；下盖3与进水槽11围成进水腔c，进水腔c设置有至少一个进水端口d；泄压盖4与主体1夹固膜片5的边缘；膜片5与过水槽13围成过水腔e，膜片5与泄压盖4围成背压腔f，背压腔f设置有至少一个泄水端口g；膜片5可变形，并随着背压腔f的压力变化打开或封堵过水腔e与排水腔a的连通处；复位件20设置在背压腔f内，用于实现膜片5向封堵过水腔e与排水腔a连通处的方向复位；背压腔f与进水腔c之间还设置有一补水通道h实现连通。
通过上述方案，本发明通过在过水槽13内设置可变形的膜片5将主体1与泄压盖4之间分隔成过水腔e和背压腔f，常态下过水腔e与背压腔f保持压力平衡，并在复位件20的作用下使得膜片5封堵过水腔e与排水腔a的连通处，当泄水端口g开启时，背压腔f压力减小，过水腔e的压力推动膜片5移动从而导通过水腔e与排水腔a实现排水，使得本发明具有排水控制功能，可以控制进水端口d所连接装置的排水，也即实现了将马桶冲水系统的排水结构集成到本发明中，简化了其储水结构（如水包）的内部结构，生产开模更容易、成本更低；本发明的进水端口d、排水端口b可以实现多向连通，实现了汇流和分流的功能，再加上上述的排水控制功能，实现了一个多功能的出水控制装置，功能更加集中，方便检修、维护。
在一些实施例中，上述上盖2上设置有通气孔21，以使排水腔a连通至大气，在本发明结束排水后排水腔a通过通气孔21补气而恢复压力，进而保持本发明内部的压力平衡。
进一步地，本发明还包括设置在通气孔21内的单向阀组件6，单向阀组件6用于开启或封堵通气孔21，在本发明排水时，单向阀组件6封堵通气孔21以防止水从通气孔21漏出，在本发明结束排水后，单向阀组件6开启通气孔21进行补气。
进一步地，上述单向阀组件6包括活动件61和密封件62，活动件61活动穿设在通气孔21中，密封件62安装在活动件61上并随活动件61的运动活动封堵通气孔21。
同时，上述上盖2的顶部设置有溢水槽22，通气孔21与溢水槽22连通，溢水槽22用于暂时储存从通气孔21中流出的水，即使单向阀组件6失效、水流从通气孔21流出，也能防止水流飞溅，从而避免影响冲水系统的其它装置的工作状态。此外，上述溢水槽22的开口处还设置有挡水盖7，挡水盖7部分遮盖溢水槽22的开口，实现通气，并进一步防止水流飞溅。
在一些实施例中，本发明还包括用于装配膜片5的活动座8，复位件20设置在泄压盖4与活动座8之间，活动座8可以保持膜片5中间部分的形状，以保证膜片5受背压腔f的压力和复位件20的作用力向排水腔a方向移动时，能够切实地封堵住排水腔a与过水腔e的连通处，避免在非排水状态下漏水的情况发生。
进一步地，活动座8的表面设置有若干限位柱81，膜片5上设置有与限位柱81匹配的限位孔51，限位柱81嵌设在限位孔51中，以实现膜片5与活动座8的相对固定。
进一步地，上述补水通道h贯通膜片5和活动座8。由于补水通道h的孔径直接决定了从进水腔c流向背压腔f的流量，因而通过改变补水通道h的孔径可以控制排水结构的补水时间，从而根据不同的需要调整本发明的排水时间，而将补水通道h设置在膜片5和活动座8上，可以通过替换不同的膜片5和活动座8达到以快速替换成合适孔径的补水通道h的目的，从而节约生产成本，又能满足不同用户的使用需求。
在一些实施例中，上述膜片5上设置有至少一圈可变形的褶皱52，褶皱52可以保证膜片5在外力的作用下具有变形的弹性空间。
在一些实施例中，上述复位件20为弹簧，泄压盖4的内壁设置有用于定位弹簧的环状凸缘41，以避免弹簧在压缩/复位的过程中位置发生变化而导致丧失使膜片5复位的功能。
在一些实施例中，上述泄水端口g由压力式冲水系统的开启阀和/或电磁阀9控制：当设置两者之一时，可以实现本发明的手动或电动开启的控制方式，也即实现手动或电动排水；当两者均设置时，可以实现本发明同时具备手动、电动开启的控制方式。
进一步地，当泄水端口g’由电磁阀9控制时，泄水端口g’可以直接连通至排水腔a，电磁阀9用于控制泄水端口g’与排水腔a的通断，也即泄压的水流也直接用于冲刷马桶，避免浪费。
在一些实施例中，上述排水端口b可以设置在主体1或上盖2上，进水端口d可以设置在主体1或下盖3上，泄水端口g可以设置在主体1或泄压盖4上，即可通过更换不同的主体1/上盖2/下盖3/泄压盖4就可以调整本发明与不同冲水系统的适配性（主要是适配不同数量的进水管、出水管的连通）。
此外，本发明是一种排水控制装置，在一些部件的连接处，必然会设置一些密封圈/环实现防漏水，在此不做赘述。
以下介绍本发明的三个具体实施例。
参考图 1 至图 6 所示，示出了本发明的第一实施例。
在第一实施例中，排水端口b具有两个，均设置在主体1上；进水端口d只有一个，设置在下盖3上；泄水端口g具有两个，均设置在泄压盖4上，两个泄水端口g分别由压力式冲水系统的开启阀和电磁阀9控制。
参考图 7 至图 12 所示，示出了本发明的第二实施例。
在第二实施例中，排水端口b具有两个，均设置在主体1上；进水端口d具有两个，均设置在下盖3上；泄水端口g具有两个，均设置在泄压盖4上，两个泄水端口g分别由压力式冲水系统的开启阀和电磁阀9控制。
参考图 13 至图 18 所示，示出了本发明的第三实施例。
在第三实施例中，排水端口b具有两个，均设置在主体1上，排水端口b外接有转接头10；进水端口d具有两个，分别设置在主体1两侧（下盖3与主体1形成一体），进水端口d外接有转接头10；泄水端口g具有两个，均设置在泄压盖4上，两个泄水端口g分别由压力式冲水系统的开启阀和电磁阀9控制。
在第三实施例中，上述转接头10具有多种外形，主要根据实际需求实现水路的转向连接。
上述实施例和图式并非限定本发明的产品形态和式样，任何所属技术领域的普通技术人员对其所做的适当变化或修饰，皆应视为不脱离本发明的专利范畴。
