 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。
参考图1至图25所示，本发明为一种压力式冲水系统及坐便器。上述的压力式冲水系统包括第一容器11和第二容器12，以及连通第一容器11和第二容器12的连通件13；所述第一容器11形成有第一进水口111和排水口112，水由第一进水口111流入第一容器11，第二容器12的水由第一容器11通过连通件13流入；进水过程中第一容器11和第二容器12中的气体逐步压缩存储在第二容器12的上部，排水时压缩气体推动第一容器11和第二容器12中的水由排水口112排出。具体如下：
如图1所示，为本发明储水结构1的结构示意图，该储水结构1包括互相独立设置的第一容器11和第二容器12，以及连通第一容器11和第二容器12的连通件13，上述连通件13的一端设置于第一容器11的顶部，其另一端穿入第二容器12的内部并贴近第二容器12的底壁。
上述储水结构1在使用时，第一容器11作为水室、第二容器12的上部作为气室、第二容器12的下部作为水室，以及连通件13会储有少量空气。在储水结构1进水时，水流先进入第一容器11，第一容器11储水并将第一容器11内部的空气挤压上升，大部分空气通过连通件13在第二容器12内压缩，少部分空气停留在连通件13的上部；第一容器11满水后水流通过连通件13进入第二容器12，第二容器12储水并将第二容器12内部的空气进一步压缩并上升，使空气在第二容器12的上部储压；在储水结构1排水时，第一容器11的水迅速排出，同时连通件13泄压、第二容器12上部的空气推动其下部的水，产生虹吸效果，使第二容器12下部的水输送至第一容器11并排出。
上述储水结构1通过将现有的压力水箱分体设计为两个互相独立的第一容器11和第二容器12，解决了现有压力水箱占据空间大、不便于安装的弊端，第一容器11和第二容器12互相独立安装，装配更加方便灵活，更适用于具有小体积需求的坐便器；其中第一容器11作为水室、第二容器12作为水气混合室，使得储水体积更大，因此在储水体积相同的条件下，第一容器11和第二容器12的总体积更小，进一步满足部分坐便器小体积的需求。
参考图2所示，上述储水结构1可应用于一种压力式冲水系统。参考图3和图4所示，为一种压力式冲水系统的第一实施例，除了包括储水结构1以外，其还包括组合阀2、排水阀3和开启阀4。上述第一容器11形成有第一进水口111和排水口112，排水阀3与排水口112相对设置，组合阀2与第一进水口111相对设置以实现第一容器11和排水阀3的独立进水，开启阀4控制排水阀3的泄压或储压以实现排水阀3的活塞31开启或封闭排水口112。
开启阀4的具体实施：
参考图5至图6所示，上述开启阀4包括阀体41、开启组件42和过压保护组件46。上述阀体41形成有进水腔411和出水腔412，进水腔411和出水腔412之间通过第一通孔413连通，进水腔411设置有连通排水口112的第一进水管道414，出水腔412设置有第一出水管道415，开启组件42与第一通孔413相对设置并开启或封闭该第一通孔413，第一通孔413开启时实现储水结构1的排水口112泄压。上述进水腔411形成有泄压孔4111，过压保护组件46与泄压孔4111相对设置且封闭该泄压孔4111，并在进水腔411的压力大于预设值时开启泄压孔4111，泄压孔4111开启时连通进水腔411和第一出水管道415。
上述第一通孔413和泄压孔4111均垂直于进水水流方向设置，泄压孔4111相对第一通孔413设置于进水水流的上游，则当进水腔411的内部压力过大时（本实施例设定水压大于3.5公斤），泄压孔4111会先于第一通孔413开启，实现泄压。
上述开启组件42包括开启杆421、第一密封件422和第一复位弹簧423，开启杆421活动穿设在第一通孔413中，第一密封件422设置在开启杆421上并位于进水腔411中。上述第一复位弹簧423设置在开启杆421的一端与进水腔411的侧壁之间，第一复位弹簧423顶压开启杆421的一端并使第一密封件422封堵第一通孔413，以阻断水流通过第一通孔413由进水腔411流入出水腔412。
上述第一密封件422具体的安装结构为：上述开启杆421的一端形成有沿开启杆421的径向凸出的第一凸缘4211，第一密封件422位于第一凸缘4211面向第一通孔413的一侧，第一复位弹簧423配合在第一凸缘4211背向第一通孔413的一侧。
上述开启组件42还包括膜片424和按钮导柱425。上述出水腔412对应开启杆421的另一端的位置设置有安装孔451，膜片424密封配合在安装孔451的内侧，开启杆421的另一端活动配合在膜片424的内侧。上述按钮导柱425连接在膜片424的外侧，并活动穿设在安装孔451中。通过设置按钮导柱425可以提高用户的操作手感，并保证按压时的施力方向与开启杆421的运动方向一致。
上述进水腔411对应开启杆421的一端形成有第一开口4112，第一开口4112处安装有后盖43，后盖43与第一开口4112之间密封配合；上述后盖43的外周与第一开口4112的侧壁之间设置有后盖密封圈44。上述第一复位弹簧423的两端分别顶压配合在开启杆421的一端和后盖43上。设置第一开口4112和后盖43，便于生产时开模形成进水腔411和后续的脱模工序。
上述出水腔412对应开启杆421的另一端形成有第二开口4121，第二开口4121处安装有前盖45，前盖45与第二开口4121之间密封配合。上述安装孔451设置在前盖45上。设置第二开口4121和前盖45，便于生产时开模形成出水腔412和后续的脱模工序。
上述过压保护组件46包括泄压盖461、第二复位弹簧462和第二密封件463。上述泄压盖461安装在出水腔412中，第二复位弹簧462的两端分别配合在泄压盖461和第二密封件463上，第二复位弹簧462顶压第二密封件463封堵泄压孔4111。当进水腔411的水压大于第二复位弹簧462的弹力时，泄压孔4111开启。
为保证过压保护组件46的工作稳定性，泄压盖461对应泄压孔4111的位置形成有弹簧固定柱4611，第二复位弹簧462的一端套设在弹簧固定柱4611上，其另一端安装有泄压台464，第二密封件463配合在泄压台464面向泄压孔4111的一面。
上述泄压盖461的外周与出水腔412的侧壁之间设置有泄压盖密封圈465。上述泄压盖461对应第一通孔413的位置形成有穿孔4612，开启杆421活动穿设在穿孔4612中并活动配合在膜片424的内侧。从而增加开启阀4的密封性，防止水从第一出水管道415以外的地方流出，并且通过第一通孔413和穿孔4612限定开启杆421的运动方向，保证开启杆421的工作稳定性。
参考图6所示，开启阀4关闭状态时（即默认状态下），第一复位弹簧423顶压开启杆421的第一凸缘4211并使第一密封件422封堵第一通孔413，第二复位弹簧462顶压泄压台464并使第二密封件463封堵泄压孔4111，则水流由第一进水管道414进入进水腔411，并在进水腔411中堆积储压。
参考图7所示，当在按钮导柱425的位置施力按压时，开启杆421向后盖43的方向移动，使第一密封件422脱离第一通孔413，由于压力式冲水系统的压力作用，水流通过第一通孔413由进水腔411进入出水腔412，并由第一出水管道415排出，实现排水阀3的泄压，则对应开启排水口112并开始排水。当撤销对按钮导柱425的施力后（松开按钮导柱425），第一复位弹簧423顶压开启杆421的第一凸缘4211并使第一密封件422复位，继续封堵第一通孔413。
参考图8所示，进水腔411内部的水压过大时（即压力式冲水系统内部水压过大），若水压大于第二复位弹簧462的压力，使第二密封件463脱离泄压孔4111，水流通过泄压孔4111由进水腔411进入出水腔412，并由第一出水管道415排出，实现压力式冲水系统的自动泄压，则对应使排水阀3开启排水口112并开始排水，避免压力式冲水系统内部过大的压力使管道、零部件受压破裂。
上述结构的开启阀4通过设置开启组件42控制第一通孔413的开闭，实现纯机械结构的控制，通过手动操作就能实现状态切换，可以节省能源，并且结构简单、操作方便，生产成本低；通过设置泄压孔4111和过压保护组件46，使得安装开启阀4的压力式冲水系统具备过压保护功能，当内部压力过大时自动泄压，以保护管道和零部件，延长其使用寿命。
上述的一种压力式冲水系统还包括稳压阀5，稳压阀5设置在组合阀2的进水端与压力式冲水系统的水源之间，以保证储水结构1内部的水压稳定，即保证压力式冲水系统的内部压力稳定，避免安全隐患。
上述的一种压力式冲水系统还包括出水盒6，出水盒6的具体实施如下：
参考图9至图15所示，上述出水盒6包括出水盒主体61和第一单向阀组件62。上述出水盒主体61形成有过水腔611、第二进水口612、至少一出水口613和通气口614，第二进水口612、出水口613和通气口614均连通过水腔611，第二进水口612与排水口112连通。上述第一单向阀组件62与第二进水口612相对设置以开启或封堵第二进水口612，在压力式冲水系统冲水结束时，第一单向阀组件62封堵第二进水口612。上述通气口614设置在过水腔611的顶部并对接大气。则当坐便器堵塞或者自来水停水的情况发生时，压力式冲水系统的内部产生负压，大气由通气口614进入，第一单向阀组件62受气压作用封堵第二进水口612，防止虹吸发生；并且过水腔611内的气压与大气保持一致，防止产生负压，避免坐便器内的水流倒灌。
上述出水盒主体61设置有若干与压力式冲水系统的功能装置连接的第二进水管道63，第二进水管道63连通过水腔611，以实现功能装置的泄压或泄水，上述功能装置包括排水阀3、开启阀4、电磁阀、稳压阀5中的至少一种，从而实现压力式冲水系统内部的压力稳定，并且保持水流在系统内部流动。
为防止压力式冲水系统排水时第二进水口612的进水与功能装置的泄水对冲，避免功能装置因泄水倒流而影响功能，上述过水腔611分隔成第一腔室611A和第二腔室611B，第二腔室611B位于第一腔室611A的上方，第一腔室611A和第二腔室611B之间设置有第二通孔615。上述第二进水口612和出水口613均连通第一腔室611A，其中第二进水口612与第二通孔615相对设置；通气口614设置在第二腔室611B的顶部，第二进水管道63连通第二腔室611B。上述第一单向阀组件62与第二通孔615相对设置以开启或封堵第二通孔615，在压力式冲水系统开启冲水时，第一单向阀组件62封堵第二通孔615。
上述出水盒6还包括与出水口613连通的第二出水管道64。上述第二出水管道64中设置有第二单向阀组件65，第二单向阀组件65在第二出水管道64中的水流流向过水腔611时封堵出水口613，从而限制第二出水管道64的水流只出不进，从而进一步提升出水盒6的防虹吸效果。
上述出水盒主体61设置有泄流管道616，泄流管道616的两端连通第二出水管道64和第二腔室611B，从而实现第二腔室611B的水、气快速泄流，最终流入坐便器进行冲刷。当出水口613的数量大于一时（即第二出水管道64的数量大于一，例如具有两个第二出水管道64的情况，如图24和图25所示，一个连接坐便器的冲圈管道300，一个连接坐便器的主冲管道200），泄流管道616最终连通坐便器的冲圈管道300。
上述出水盒主体61分体设计为上壳61A和下壳61B，上壳61A和下壳61B密封配合。上述第二腔室611B形成于上壳61A，第一腔室611A形成于下壳61B，以便于出水盒主体61生产时脱模形成第一腔室611A和第二腔室611B。
上述第一单向阀组件62包括阀片621和密封胶垫622，阀片621的两面均设置有密封胶垫622，两面的密封胶垫622分别活动封堵第二进水口612和第二通孔615。
上述出水盒6还包括第三单向阀组件66，第三单向阀组件66与通气口614相对设置以开启或封堵通气口614，在压力式冲水系统冲水结束时，第三单向阀组件66开启通气口614。上述第三单向阀组件66包括活动件661和密封圈662，活动件661活动穿设在通气口614中，密封圈662套设在活动件661的外周并随活动件661的运动活动封堵通气口614；上述活动件661的上端形成有活动钩扣在通气口614上方周缘的卡钩6611，以防止活动件661受重力作用向下脱离通气口614，从而保证第三单向阀组件66的工作稳定性。
上述出水盒主体61的顶部形成有溢水槽617，通气口614与溢水槽617连通，溢水槽617用于暂时储存从通气口614中流出的水，防止水流从通气口614溅出，从而避免影响压力式冲水系统的其它功能装置的工作状态。上述溢水槽617的开口处设置有挡水片618，挡水片618部分遮盖溢水槽617的开口，实现通气，并进一步防止水流飞溅。
参考图12和图13所示，当压力式冲水系统处于储水状态时，第一单向阀组件62受重力作用向下摆动并封堵第二进水口612，第三单向阀组件66受重力作用向下运动并打开通气口614，此时第一腔室611A和第二腔室611B对接大气，第二腔室611B的少量进水（排水阀3、开启阀4、电磁阀和稳压阀5等泄压的水流）分别流入第一腔室611A和泄流管道616，最终由出水口613排出；此外，第二单向阀组件65受重力和逆流的水压作用向下摆动，最终封堵出水口613（当出水口613数量大于一时，封堵的是与坐便器的主冲管道200连通的出水口613）。
参考图14和图15所示，当压力式冲水系统处于排水状态时，第一单向阀组件62受水压作用向上摆动，水流进入第一腔室611A，并分流至第二腔室611B和出水口613（仅少量水流进入第二腔室611B，因为第一单向阀组件62会被水流顶起封堵第二通孔615），第二腔室611B的水流将第三单向阀组件66向上顶起，使通气口614封堵，以防水流溅出出水盒主体61；此时，第二单向阀组件65被水流顶开，实现排水。
上述的出水盒6通过在过水腔611内设置第一单向阀组件62活动封堵第二进水口612，可以实现出水盒主体61的防虹吸功能；并且通过设置通气口614对接大气，能够保证过水腔611内部的压力与大气一致，不会产生负压，从而避免出水口613的水流被倒吸。上述出水盒6独立于压力式冲水系统的储水结构1设置，可以根据需求高度进行安装，进一步提升防虹吸的效果。
此外，将压力式冲水系统的功能装置连通过水腔611，可以保证压力式冲水系统内部的压力平衡；当出水口613的数量为多个时，上述出水盒6还可以实现水流分流的功能，为坐便器的不同管道供水。
参考图16所示，当压力式冲水系统的第一实施例进水过程为：水源管道的水经过稳压阀5进入组合阀2，并分别流入第一容器11和排水阀3，使排水阀3的活塞31封堵排水口112，第一容器11储水并将第一容器11内部的空气挤压上升，进入连通件13，第一容器11满水后第二容器12开始储水并将第二容器12内部的空气挤压上升，使空气在第二容器12的上部储压，此时连通件13和第二容器12的上部均有压缩空气。
参考图17所示，当压力式冲水系统的第一实施例排水过程为：操作开启阀4，使排水阀3泄压，活塞31脱离排水口112，第一容器11的水迅速排出，同时连通件13泄压、第二容器12上部的压缩空气推动其下部的水，产生虹吸效果，使第二容器12下部的水输送至第一容器并排出排水口112；第一容器11的水经过第二进水管道63进入分水盒3，并由第二出水管道64流出，最终进入坐便器进行冲水。
参考图18所示，为一种压力式冲水系统的第二实施例，其与第一实施例的不同之处在于，上述第二容器12内设置有调节装置7。调节装置7的具体实施如下：
参考图19至图21所示，上述调节装置7包括将第二容器12分隔成水室和气室的水气隔板71，以及排气调节组件72。上述水气隔板71设置有连通第二容器12的水室和气室的排气口7111，排气调节组件72与排气口7111相对设置并活动调节排气口7111的排气量大小。
上述排气调节组件72的下端安装在排气口7111处，其上端向上穿出第二容器12，通过操作排气调节组件72在第二容器12上表面外部的部分，即可实现第二容器12内部的水气隔板71的排气口7111的排气量调节。上述排气调节组件72的上端位于第二容器12的顶部，更方便于用户操作，且占据的横向空间更小，不会干扰储水结构1在坐便器陶瓷内的安装。
上述水气隔板71形成有安装管道711，排气口7111设置在安装管道711的侧壁。上述排气调节组件72与安装管道711密封配合，并设置有连通水室的排气管道7211，排气管道7211形成有与排气口7111对应设置的进气口7212。上述排气调节组件72用以调节进气口7212与排气口7111的相对位置，从而改变排气口7111的截面大小。上述安装管道711具有竖直向上的开口，排气调节组件72安装在开口中并竖直向上穿出第二容器72。
上述排气调节组件72包括调节阀721和调节钮，本实施例中调节钮包括调节杆722和旋钮723，调节阀721与调节杆722的一端连接，并密封配合在安装管道711内，上述排气管道7211设置在调节阀721上。上述调节杆722的另一端穿出第二容器12，并与旋钮723连接。上述调节杆722的另一端与第二容器12密封配合（或者旋钮723的外周与第二容器12密封配合）。此外，调节阀721是通过调节杆722与旋钮723连接，即调节钮的调节杆722和旋钮723是分体设计的；当然，也可以将调节钮的调节杆722和旋钮723作为一体设计，使得调节阀721直接与调节钮连接。
上述调节阀721的外周套设有调节阀密封圈724，调节阀密封圈724密封配合在调节阀721与安装管道711之间，以提高产品的密封性；上述进气口7212贯穿调节阀密封圈724。
上述安装管道711一端的开口处设置有安装台阶7112，调节阀721对应安装台阶7112的位置设置有第二凸缘7213，第二凸缘7213配合在安装台阶7112上；调节阀721穿入安装管道711，并通过C型扣725限位配合在安装管道711的另一端。从而实现调节阀721在安装管道711内的限位配合，提高调节阀721转动时的稳定性。
上述水气隔板71形成有供连通件13穿设的第三通孔712，连通件13与第三通孔712之间通过第一密封环73实现密封配合，以防止气室的压缩空气从第三通孔712进入水室。
上述水气隔板71与第二容器12的侧壁之间通过第二密封环74实现密封配合。
参考图20和图21所示，调节装置7通过水气隔板71实现第二容器12水气隔离，并通过调节阀721垂直于上下方向的转动实现进气口7212和排气口7111的相对位置调节。具体操作为通过拧转旋钮723，使调节杆722带动调节阀721转动，即可改变进气口7212和排气口7111的相对位置，进而改变排气口7111的截面大小.即排气量大小。当然，排气调节组件72不限制于上述的结构，只要能够实现手动调节排气口7111排气量的装置或结构都适用于上述的调节装置7。
上述调节装置7通过设置排气调节组件72，能够调节排气口7111的排气量大小，即调节压缩空气的释放速度，实现根据需求调节储水结构1的排水速度，提高储水结构1与不同管道类型的坐便器的通配性，并具有结构简单、方便操作的优势。
参考图22所示，压力式冲水系统的第二实施例进水过程为：水源管道的水经过稳压阀5进入组合阀2，并分别流入第一容器11和排水阀3，使排水阀3的活塞31封堵排水口112，第一容器11储水并将第一容器11内部的空气挤压上升，进入连通件13，第一容器11满水后第二容器12开始储水并将第二容器12内部的空气挤压上升通过排气口7111，使空气在水气隔板71的上方储压，此时连通件13和第二容器12的上部均有压缩空气。
参考图23所示，压力式冲水系统的第二实施例排水过程为：操作开启阀4，使排水阀3泄压，活塞31脱离排水口112，第一容器11的水迅速排出，同时连通件13泄压、第二容器12上部的压缩空气通过排气口7111排出并推动其下部的水，产生虹吸效果，使第二容器12下部的水输送至第一容器并排出排水口112；第一容器11的水经过第二进水管道63进入分水盒3，并由第二出水管道64流出，最终进入坐便器进行冲水。
参考图24和图25所示，上述压力式冲水系统可应用于坐便器中，压力式冲水系统安装在坐便器的容置腔100中，且储水结构1的排水口112连通至坐便器的冲洗管道。本实施例中坐便器的冲洗管道包括主冲管道200和冲圈管道300（当设置有出水盒6的时候，出水盒6的多个第二出水管道64分别连通至坐便器的主冲管道200和冲圈管道300）。
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。
