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。
参考图1所示，本发明公开了一种双水包结构，包括第一容器1、第二容器2和连通管道3；第一容器1的上部设置有补水口a和补气口b；第二容器2的下部设置有排水口c，且第一容器1的侧面底部与第二容器2的侧面底部通过连通管道3连通；补水时，水由补水口a流入第一容器1，气体由补气口b流入第一容器1，且水与气体混合后由连通管道3流入第二容器2，且气体逐步压缩并存储在第一容器1、第二容器2的上部；排水时，压缩气体推动第一容器1的水通过连通管道3流入第二容器2、第二容器2中的水由排水口c排出。
以下示出了上述双水包结构的具体实施方式。
上述补水口a设置在第一容器1的侧面顶部，补气口b设置在第一容器1的上端面，排水口c设置在第二容器2的侧面底部。
上述双水包结构还包括设置在第一容器1内的输入管道11，输入管道11延伸至第一容器1的下部；补水口a、补气口b均连通至输入管道11。将输入管道11贴近第一容器1的底部，使得气体与水混合后更容易通过连通管道3进入第二容器2，实现向第二容器2补气。
上述连通管道3的的直径不小于15mm，以保证第二容器2的补水补气效果。
上述连通管道3为弧形管道，并向远离坐便器排污管的方向弯曲，在坐便器的陶瓷空间内安装时可以更容易避开其排污管的位置，避免被排污管影响安装位置。
参考图2至图4所示，本发明还公开了一种压力式冲水系统，包括上述的双水包结构，以及补水补气机构、排水机构和控制机构；补水口a、补气口b均通过补水补气机构进入第一容器1；排水机构设置在排水口c，并与控制机构进行联动；控制机构工作时排水机构开启，以使排水口c排水。
以下示出了上述压力式冲水系统的具体实施方式。
参见图3和图4，上述补水补气机构包括安装盖5、活塞件6和第一弹簧7；第一容器1的上端面凹陷形成有安装槽12，安装槽12的底部连接有输入管道11；安装盖5与安装槽12的侧壁密封配合，其上端面不高于第一容器1的上端面；安装盖5内设置有竖向并列的进水通道51和进气通道52，补水口a设置在进水通道51的侧壁，补气口b设置在进气通道52的上端，进气通道52的下端与输入管道11连通；活塞件6活动配合在进气通道52内；第一弹簧7设置在活塞件6与安装槽12的底壁之间；活塞件6在第一容器1内外的压力差和第一弹簧7的弹力共同作用下实现在进气通道52内移动以打开或封闭补气口b。该补水补气机构通过在第一容器1的上端面凹陷形成安装槽12，安装槽12用于装配安装盖5，且安装盖5内设置进气通道52用于装配活塞件6和第一弹簧7组成压力式冲水系统的进气结构，使得进气结构与第一容器1形成一个整体，且安装盖5的上端面不高于第一容器1的上端面，因此不会增加双水包结构的高度，更适用于矮小空间内的安装；相比于传统的进气装置，该补气补水机构零件更少，结构更简单，组装更方便、效率更高。
在上述补水补气机构的一些实施方式中，上述进气通道52的上端设置有第一环斜面53，使得进气通道52的输入端的半径沿着进气方向逐渐增大，呈扩口设计；活塞件6的上端部设置有堵头61，堵头61与活塞件6的连接处为第二环斜面62；随着活塞件6在进气通道52内的移动，第二环斜面62贴合或远离第一环斜面53，堵头61活动穿设于补气口b。第一环斜面53、第二环斜面62增大了活塞件6与补气口b的接触面积，使得常态下的密封效果更好（此处的常态指的是双水包结构完成补水补气之后）；堵头61起到活塞件6移动时的导向作用，保证第二环斜面62与第一环斜面53的贴合度。
进一步地，上述堵头61与第二环斜面62的衔接处设置有第一环槽63，第一环槽63内设置有第一密封环81，第一密封环81随着活塞件6在进气通道52内的移动贴合或远离第一环斜面53，进一步提高活塞件6与补气口b之间的密封效果。
在上述补水补气机构的一些实施方式中，上述活塞件6的下端部凹陷形成有第一限位槽64，安装槽12的底壁设置有与第一限位槽64相对的第二限位槽13，第一弹簧7的两端分别配合在第一限位槽64、第二限位槽13内，从而可以提高第一弹簧7的位置稳定性，进而保证进气结构的功能稳定性。
进一步地，上述活塞件6为中空的壳结构，以形成上述的第一限位槽64，同时第一限位槽64与第二环斜面62位置相对的内壁上设置有若干加强筋65，第一弹簧7的上端抵靠在加强筋65上。将活塞件6设计成中空的壳结构，可以减轻活塞件6的重量，避免其自身重力过多地抵消第一弹簧7的弹力，同时增加加强筋65后既保证第一弹簧7的配合位置，又能提高活塞件6的第二环斜面62的强度。
在上述补水补气机构的一些实施方式中，上述进气通道52为设置在安装盖5内的管道，其下端与安装槽12的底壁间隙配合，以避免安装盖5安装在第一容器1上后安装槽12堵住进气通道52，从而使得进气通道52可以与输入管道11连通。
在上述补水补气机构的一些实施方式中，上述补水补气机构还包括嵌设在进水通道51输出端的文丘里喷嘴9，文丘里喷嘴9不阻断进气通道52与输入管道11的连通，且文丘里喷嘴9的输出端插入输入管道11的输入端。文丘里喷嘴9的输出端相对于其输入端缩口、管径更小，使得水流在经过文丘里喷嘴9后实现加速，再高速流向输入管道11，从而在输入管道11、进气通道52中产生负压，进而使得第一容器1外的气压抵抗第一弹簧7的弹力而推动活塞件6以打开补气口b进行补气。
进一步地，上述文丘里喷嘴9的输入端与进水通道51的输出端之间设置有第二密封环82，以实现密封连接；文丘里喷嘴9的周面设置有若干限位凸出部91，限位凸出部91之间的间隙为过气槽92；进水通道51的下端与输入管道11的上端夹设在限位凸出部91的上下表面，以实现对文丘里喷嘴9的限位，保证组装后文丘里喷嘴9的位置稳定性，同时过气槽92可以保证进气通道52与输入管道11的连通。
在上述补水补气机构的一些实施方式中，上述安装盖5的侧面设置有与补水口a轴向连通的进水管接头54，用于连接压力式冲水系统的进水管d。将进水管接头54设置在安装盖5的侧面，使得进水管d的上端在连接时是横向的，不会超出第一容器1的上端面。
进一步地，上述安装槽12的侧边设置有限位缺口14，进水管接头54与安装盖5之间连接有连接部55，连接部55嵌设在限位缺口14内，实现安装盖5在安装槽12内的限位配合，之后通过螺丝锁固将安装盖5固定在安装槽12内，完整组装。
在上述补水补气机构的一些实施方式中，上述安装盖5的下端面周缘设置有一圈台阶56，台阶56上套设有第三密封环83，安装盖5与安装槽12装配后第三密封环83紧配合在安装盖5与安装槽12的侧壁之间，实现密封配合。
上述输入管道11内设置有第三环斜面15，第三环斜面15的半径沿着输入方向逐渐减小，也即输入管道11也做缩口设计，可以实现对输入管道11内的水、气体的加速效果。
参见图5，上述排水机构包括底盖10和膜片20；第二容器2设置有储水腔21、排水槽22和排水管23；排水槽22凹陷形成于第二容器2的底部，其上内壁分别与储水腔21、排水管23连通，排水口c位于排水管23的输出端；底盖10密封连接在排水槽22的开口处；膜片20活动配合在排水槽22与排水管23的连通处，并与底盖10围成背压腔e；背压腔e设置有连通背压腔e与储水腔21的补水孔f，以及至少一个泄水口g，泄水口g与控制机构连通；储水腔21供水时，水通过补水孔f进入背压腔e，使背压腔e压力增大；打开泄水口g时，背压腔e泄水而使压力减小；膜片20随着背压腔e的压力变化靠近或远离排水管23，以此封堵或打开排水管23。
该排水机构具有以下改进：①通过在排水槽22内设置可活动的膜片20，膜片20与底盖10之间形成背压腔e，背压腔e设置有泄水口g，当背压腔e泄压时，储水腔21的水压将推动膜片20使其脱离排水管23，实现储水腔21与排水管23之间的水路连通，储水腔21即可向外排水，供水先进入储水腔21后，再顶开膜片20并进入排水管23，无论第二容器2进水的压力如何变化，都是在向排水管23排水的同时对膜片20提供开启方向的推力，进而保证排水的稳定性，使得压力包的排水不受供水压力和流量变化的影响；②通过设置补水孔f，确保无论膜片20如何变化，都能够在排水后及时向背压腔e补水，恢复原有的压力以推动膜片20封闭排水腔b与排水管23的连通处；③第二容器2的整体排水设置在底部位置，连通用的管道可以排布在第二容器2的侧边，从而降低双水包结构的整体高度，进而适配较矮的安装空间。
在上述排水机构机构的一些实施方式中，还包括设置在背压腔e内的第二弹簧30，第二弹簧30用于实现膜片20向排水管12方向复位。通过设置第二弹簧30，可以保证排水时膜片20不会完全贴到底盖10上而使背压腔e无法补水，且在排水后实现膜片20的复位，进而保证了排水结构反复工作的功能稳定性。
进一步地，上述排水机构还包括用于装配膜片20的活动座40；第二弹簧30设置在底盖10与活动座40之间。通过设置活动座40可以保持膜片20中间部分的形状，以保证膜片20受背压腔e的压力和第二弹簧30的作用力向排水管23方向移动时，能够切实地封堵住排水管23的进水端，避免在非排水状态下漏水的情况发生。
其次，上述底盖10与活动座40的相对面分别设置有第一凸环101、第二凸环401，第二弹簧30的两端分别嵌设在第一凸环101、第二凸环401内，以实现第二弹簧30在背压腔e内的固定，从而避免第二弹簧30在压缩/复位的过程中位置发生变化而导致丧失使膜片20复位的功能。
再者，上述活动座40的表面设置有限位柱402，膜片20上设置有与限位柱402匹配的限位孔201，限位柱402嵌设在限位孔201中，以实现膜片20与活动座40的相对固定。
最后，上述补水孔f贯通膜片20和活动座40。由于补水孔f的孔径直接决定了从储水腔21流向背压腔e的流量，因而通过改变补水孔f的孔径可以控制本发明的补水时间，从而根据不同的使用需求调整排水时间，而将补水孔f设置在膜片20和活动座40上，可以通过替换不同的膜片20和活动座40达到以快速替换成合适孔径的补水孔f的目的，从而节约生产成本，又能满足不同用户的使用需求。
在上述排水机构机构的一些实施方式中，上述排水槽22的侧壁设置有一圈限位槽221，膜片20的边缘设置有一圈限位环202，底盖10压紧限位环202配合在限位槽221内，以实现膜片20在第二容器2内的安装；且膜片20上设置有至少一圈可变形的褶皱203，褶皱203可以保证膜片20在外力的作用下具有变形的弹性空间。
在上述排水机构机构的一些实施方式中，上述泄水口g设置在底盖10的侧边。相对于第二容器2，底盖10属于比较容易替换的部件，将泄水口g设置在底盖10上，可以根据使用需求替换具有不同泄水口g数量的底盖10，调节起来更加方便；同时，泄水口g设置在底盖10的侧向位置，可以横向连接管道而不造成拐角，避免占用高度空间。
上述泄水口g的数量可以根据控制方式的不同设置一个或多个，以满足不同用户的使用需求。
进一步地，上述控制机构包括开启阀41、电磁阀42中的至少一种，当两者都设置时，开启阀41、电磁阀42分别与不同的泄水口g连通；（1）当控制机构为开启阀41时，开启阀41即泄水口g的“控制开关”，用户按压开启阀41时，可以将背压腔e内的水通过泄水口g排出，使得背压腔e的压力减小，从而使膜片20脱离排水管23的进水端以达到排水的目的。
（2）当控制机构为电磁阀42时，电磁阀42的进水端与其一泄水口g连通，其出水端连通至排水管23。当电磁阀42工作时，实现泄水口g（也即背压腔e）与排水管23的直接导通，可以将背压腔e内的水排到排水管23内，使得背压腔e的压力减少，从而使膜片20脱离排水管23的进水端以达到排水的目的。由于电磁阀42可以方便无线远程控制，直接将电磁阀42的出水端连通至排水管23还可以节省管道连接的成本，并避免占用空间（可直接在第二容器2内设计通路）。
上述压力式冲水系统还包括分水盒50；控制机构、排水机构的输出端均连通至分水盒50；分水盒50设置有至少两个排水接头501，两个排水接头501用于连通坐便器的主冲管道和冲圈管道。设置分水盒50可以简化排水机构的向外输出管道的连接，并且可以根据实际需求向不同的水路供水。
参考图5和图6所示，上述压力式冲水系统的工作原理如下。
在进水时：由进水管d向第一容器1供水，第一容器1开始补气补水，同时通过连通管道3向第二容器2补气补水，气体逐步压缩并存储在第一容器1、第二容器2的上部；在第二容器2中，水流由补水孔f流入背压腔e，并逐渐推动膜片20向排水管23移动，直至膜片20堵住排水管23的进水端，与此同时第一容器1、第二容器2内的气体压缩使容器内的压力上升，直至与进水管d的水压保持平衡，完成进水。
在排水时：用户操作开启阀41或电磁阀42打开泄水口g，背压腔e内的水通过泄水口g排到分水盒，背压腔e内的压力下降，储水腔21的水压推开膜片20以打开排水管23的进水端，开始排水；排水管23排水使第一容器1、第二容器2内的压力降低，进水管d开始向第一容器1供水，水流也通过补水孔f向背压腔e补水，此时泄水口g关闭，背压腔e补水，使得膜片20缓慢向排水管23复位，在设定的排水时间（由补水孔f的孔径与背压腔e的最大容量决定）结束后，膜片20再次封堵排水管23，结束排水。
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。
