四路分配阀及马桶冲刷系统和马桶
本申请要求2022年8月18日向中国国家知识产权局申请，申请号为：202210993762.0，发明创造名称是：“四路分配阀及马桶冲刷系统和马桶”的中国专利申请为基础，并主张其优先权，该中国专利申请的公开内容在此作为整体引入本申请文本中。
技术领域
本发明涉及分配阀领域，尤其涉及一种四路分配阀及马桶冲刷系统和马桶。
背景技术
分配阀作为水路分配的重要部件，在卫浴领域受到广泛的关注。其中，在马桶领域，对于进水水路分配，大多采用一进两出的分配阀，主要采用单一进水实现刷圈出水和喷射出水，容易存在进水水路难以满足刷圈出水和喷射出水的供水要求。因此可以采用自来水进水或泵压水进水实现刷圈出水和喷射出水解决该问题，泵压水需要在水泵通电的情况下才能实现进水，而在水泵断电情况下，可以切换由自来水管道提供进水；或者在自来水管道缺水的情况，可以通过泵压水提供进水，以满足不同场景的进水需求。因此亟需一种两进两出的分配阀，实现自来水或泵压水的进水水路分配以及刷圈或喷射的出水水路分配。
现有分配阀大部分均为一进两出，对于出水水路分配，主要实施方式为步进电机控制切换片转动，实现两个出水口的切换，无法满足两进两出的需求，并且切换片承受水压，切换力较大，对步进电机扭力要求高。

实施例一
参考图1-15，本发明的实施例提出了一种四路分配阀，包括阀体总成100和切换组件200，阀体总成100设有第一进水腔101、第二进水腔102、第一连通腔103、第一出水腔106、第二出水腔107、第二连通腔108和活动止水部件300，第一进水腔101设有第一进水口，第二进水腔102设有第二进水口，第一出水腔106设有第一出水口，第二出水腔107设有第二出水口，第一进水腔101与第一连通腔103连接，第一连通腔103与第一进水腔101之间具有第一连通口104，第二进水腔102与第一连通腔103连接，第一连通腔103和第二进水腔102之间具有第二连通口105，活动止水部件300活动设置于第一连通腔103中，并在第一进水腔101进水时，受水压推动而关闭第二连通口105；在第二进水腔102进水时，受水压推动而关闭第一连通口104，通过设置在第一连通腔103内的活动止水部件300切换第一进水腔101与第一连通腔103之间的第一进水水路的导通或者第二进水腔102与第一连通腔103之间的第二进水水路的导通。第一连通腔103与第二连通腔108导通，第一出水腔106与第二连通腔108连接，第二出水腔107与第二连通腔108连接，切换组件200设置于阀体总成100中，并控制第二连通腔108与第一出水腔106连通或第二连通腔108与第二出水腔107连通，通过切换组件200切换第一出水腔106与第二连通腔108之间的第一出水通道的导通或者第二出水腔107与第二连通腔108之间的第二出水通道的导通。
在具体的实施例中，参考图6-10，第一连通腔103为设置在第二进水腔102外侧的环形柱状空间，活动止水部件300包括套设于第二进水腔102外壁并限位移动于第一连通口104与第二连通口105之间的止水阀片301。作为优选，止水阀片301为单向止水阀片。在其中一个实施例中，阀体总成100内密封固定有连接管111，与阀体总成100构成第二进水腔102，该连接管111的外壁设有两个限位凸沿，止水阀片301套设于连接管111的外壁，并限位移动于两个限位凸沿之间。具体的，初始状态时，受止水阀片301的重力作用，该止水阀片301处于第一连通口104处，使第二进水腔102与第一连通腔103导通，第一进水腔101与第一 连通腔103截止；参考图6-8，当第一进水腔101进水时，受水压推动该止水阀片301从第一连通口104处移动至第二连通口105处，并封堵住第二连通口105，使第一进水腔101与第一连通腔103导通，第二进水腔102与第一连通腔103截止；参考图9-10，当第二进水腔102进水时，受水压推动该止水阀片301抵在第一连通口104处，并封堵住第一连通口104，使第二进水腔102与第一连通腔103导通，第一进水腔101与第一连通腔103截止。因此可避免第一进水腔101的进水进入到第二进水腔102中，或者，第二进水腔102的进水进入到第一进水腔101中。本发明通过不同进水水路的水压推动实现第一进水腔101或第二进水腔102的自由切换。第一进水腔101或第二进水腔102的进水进入第一连通腔103中，第一连通腔103与第二连通腔108导通，因此，随即也进入到第二连通腔108中。在第二连通腔108中通过切换组件200实现切换与第一出水腔106或第二出水腔107的导通以及出水。
在具体的实施例中，切换组件200包括第一止水膜片201、第二止水膜片202和滑杆203，第一止水膜片201套装于滑杆203的一端，第二止水膜片202套装于滑杆203的另一端，第二连通腔108与第一出水腔106之间具有第三连通口109，第二连通腔108与第二出水腔107之间具有第四连通口110，该滑杆203在第二连通腔108内限位移动，使得第一止水膜片201封堵在第三连通口109，第二止水膜片202开启第四连通口110，或者，使得第一止水膜片201开启第三连通口109，第二止水膜片202封堵在第四连通口110。第一止水膜片201将第二连通腔108分隔为过水腔204和背压腔205，第一止水膜片201在靠近背压腔205一侧设有背压膜，背压膜呈喇叭状，具有较大的表面积，在靠近过水腔204一侧设有封堵部，封堵部与第三连通口109相对，并且封堵部的面积略大于第三连通口109的连通面积，背压腔205设有泄压口206，第一止水膜片201上设有连通过水腔204和背压腔205的细小孔207，并且第一止水膜片201靠近背压腔205一侧的表面积大于靠近过水腔204一侧的表面积，使得在泄压口206关闭的情况下，背压腔205内 的受压面大于过水腔204的受压面。利用第一止水膜片201两侧的压差从而带动滑杆203左右移动，进而实现第二连通腔108分别与第一出水口或第二出水口的连通，结构可靠性好，操作更省力；另外在滑杆203外套设有密封圈208，使得滑杆203上下滑动实现水路切换的同时实现第二连通腔108与第一出水口或第二出水口的单向导通，避免第二连通腔108与第一出水口和第二出水口同时导通。参考图13-15，在泄压口206开启时，背压腔205泄压导致压力下降，由于细小孔207的孔径较小，背压腔205的进水比较慢，过水腔204进水快，因此，此时过水腔204的进水压力是大于背压腔205，受过水腔204内水压的推动，滑杆203朝一端移动，并使第二止水膜片202关闭第四连通口110，同时第一止水膜片201开启第三连通口109；参考图11-12，在泄压口206关闭时，过水腔204内的进水从细小孔207进入到背压腔205内，由于背压腔205的受压面较大，受背压腔205的背压推动，滑杆203朝向另一端移动，并使第一止水膜片201关闭第三连通口109，同时第二止水膜片202开启第四连通口110。
在具体的实施例中，过水腔204包括第一腔体209和第二腔体210，第三连通口109设置在第一腔体209与第一出水腔106之间，第四连通口110设置在第一腔体209与第二腔体210之间，第二腔体210与第二出水腔107导通，滑杆203滑动穿设于第一腔体209，且其局部密封穿出第一腔体209，并进入第二腔体210内，第二止水膜片202设于第二腔体210内。
具体的，滑杆203一端设有固定架，用于卡接第一止水膜片201，固定架与细小孔207对应的位置设有一细水柱，细水柱穿过细小孔207；滑杆203的一端穿过第三连通口109，另一端穿过第四连通口110，第一止水膜片201位于第三连通口109外侧，第二止水膜片202位于第四连通口110外侧。
具体的，滑杆203上还套装有密封圈208，该密封圈208在滑杆203穿出第三连通口109时与第三连通口109密封配合。进一步的，密封圈208的径向截面呈V字形，保证其在移动过程中具有较低的密封阻力。
在具体的实施例中，参考图4，切换组件200还包括驱动机构，驱动机构控制泄压口206的开启或关闭。具体的，驱动机构包括电机211、切换转子212、切换拉杆213和泄压口开闭组件，通过切换拉杆213移动至第一状态或第二状态以驱动泄压口开闭组件开启或关闭泄压口206。在其中一个实施例中，泄压口开闭组件包括固定支架214、传动杆215、连接块216、堵头217和复位弹簧218，切换拉杆213与传动杆215一端铰接，用于控制传动杆215移动；固定支架214具有内腔，传动杆215的另一端置于内腔且通过连接块216连接用于启闭泄压口206的堵头217，复位弹簧218套装在连接块216外，用于复位堵头217。在其他实施例中，也可以采用其他等效或类似的机构，用于实现泄压口206的开闭。参考图13，切换转子212由电机211驱动，切换转子212驱动切换拉杆213移动，且切换转子212上设有使切换拉杆213移动至第一状态的第一驱动部以及使切换拉杆213移动至第二状态的第二驱动部。当切换转子212的第一驱动部与切换拉杆213接触，切换拉杆213处于第一状态，此时泄压口206处于开启状态，实现第一止水膜片201对第三连通口109的开启，第二止水膜片202对第四连通口110的封堵，关闭第二出水通道，第二连通腔108内的进水从第一出水腔106流出；当切换转子212的第二驱动部与切换拉杆213接触，切换拉杆213处于第二状态，此时泄压口206处于关闭状态，实现第一止水膜片201对第三连通口109的封堵，第二止水膜片202对第四连通口110的开启，关闭第一出水通道，第二连通腔108内的进水从第二进水腔102流出。在其他实施例中，驱动机构中也可以采用机械开关或电磁阀头等实现对切换拉杆213的移动。第一出水通道与第二出水通道的切换主要通过控制泄压口206的启闭，执行驱动机构开启泄压口206所需要的力不受水压影响，对电机211扭力要求低。
本发明的实施例还提出了一种马桶冲刷系统，包括泵压水进水管、自来水进水管、喷射管道、刷圈管道，以及上述的四路分配阀，泵压水进水管可连接水泵，自来水进水管与角阀连接，第一进水口与泵压水进水管连接，第二进水口与自来 水进水管连接，第一出水口与喷射管道连接，实现喷射出水，第二出水口与刷圈管道连接，实现刷圈出水。本发明的四路分配阀的第一进水口和第二进水口可分别与泵压水进水管和自来水进水管连接，在马桶处于通电状态，与泵压水进水管连接的水泵也处于开启状态，可以实现泵压水进水管持续向第一进水腔101内进水，满足喷射出水或刷圈出水的水压要求；而当马桶处于断电状态下，水泵处于关闭状态，泵压水进水管内的水压不足，此时，可开启角阀，使自来水进水管中的进水进入第二进水腔102内，自来水的进水压力能够满足喷射出水或刷圈出水的水压要求。
具体的，在自来水进水管或自来水进水管与第二进水口连接处设有防虹吸阀，避免前端水源有负压时，污水导流，污染自来水水源。
本发明还提供了一种马桶，包括便池，还包括上述马桶冲刷系统，所述刷圈管道连通所述便池顶部设置的刷圈孔或刷圈喷头，所述喷射管道连通所述便池底部设置的喷射口或喷射喷头。
实施例二
本发明的实施例二与实施例一的区别在于：阀体总成100上还集成了防虹吸阀。参考图16-29，在具体的实施例中，阀体总成100还设有连通第二进水腔102的大气口220，大气口220由设置于第二进水腔102内的防虹吸浮子219控制启闭。具体的，防虹吸浮子219设置在第二进水腔102与第一连通腔103之间的连通路径上，并受第二进水腔102内的进水压力推动而关闭大气口220。在其中一个实施例中，大气口220设置在防虹吸盖221上，防虹吸盖221安装在第二进水腔102上方。防虹吸浮子219设置在连接管111顶部，并限位移动于连接管111顶部与大气口220之间，在初始状态下，防虹吸浮子219受到重力作用位于连接管111顶部，此时大气口220打开，阀体总成100内部与空气连通，可避免前端水源有负压时，污水导流，污染自来水水源。当第二进水腔102进水时，在进水压力的推动下，防虹吸浮子219封堵住大气口220，与大气的通道关闭，进水继续往第一 连通腔103内流动，并推动止水阀片301封堵住第二连通口105，水不会流到第一进水腔101。
其余部分与实施例一相同，在此不再赘述。
上述实施例仅用来进一步说明本发明的技术方案，但本发明并不局限于实施例，凡是依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均落入本发明技术方案的保护范围内。
工业实用性
