下面参考图1和图2描述根据本发明实施例的过滤水系统100。
如图1和图2所示，根据本发明实施例的过滤水系统100，过滤水系统100包括：滤芯组件10、进水管20、纯水管路40、净水管路30、排污管路50和循环管路70。
具体而言，如图1和图2所示，滤芯组件10具有进水口110、净水出口120和纯水出口140。需要说明的是，滤芯组件10可以为一体化复合滤芯。例如，滤芯组件10可以包括：前置滤芯、精细过滤滤芯和后置滤芯。采用一体化复合滤芯，可以简化过滤水系统100，优化管路布局，而且可以实现不同滤芯同步更换，使用方便。进水管20与进水口110连通，进水管20上设置有进水控制阀210。由此，可以通过控制进水控制阀210控制原水从进水管20进入到过滤水系统100中。这里所述的“原水”可以是指从水龙头直接流出的水，也可以是指井水或储水等。例如，原水在滤芯组件10内的过滤顺序可以为：前置滤芯→精细过滤滤芯→后置滤芯。
纯水管路40与纯水出口140连通，经过滤水系统100制得的纯水可以从纯水管路40流出。净水管路30与净水出口120连通，净水管路30具有用于控制净水管路30通断的第一阀体320。由此，可以通过第一阀体320控制净水管路30的通断。排污管路50与净水管路30连通，且排污管路50的一端位于第一阀体320和净水出口120之间。由此，在制备纯水过程中产生的废水可以从排污管路50排出过滤水系统100。循环管路70的一端与进水管20连通，另一端与排污管路50连通。由此，废水管路50中的废水可以部分从循环管路70中返回至过滤水系统100中，进行再次过滤利用。
其中，当过滤水系统100制净水时，如图1所示，净水管路30连通，纯水管路40和排污管路50断开(如图1中虚线管路所示)。水流在过滤水系统100内沿箭头：a1→a2→a3所示的方向流动。如图1所示，原水从进水管20经过进水口110进入到滤芯组件10内进行初步过滤得到净水，净水经过净水出口120流出滤芯组件10，并经过净水管路30流出，由此，经过初步过滤得到的净水可以作为清洗衣物、浇花、沐浴等生活用水。
当过滤水系统100制纯水时，如图2所示，纯水管路40以及排污管路50连通，第一阀体320关闭，净水管路30断开(如图2中虚线管路所示)，纯水管路40和排污管路50连通。水流在过滤水系统100内沿箭头：a1→b2所示的方向流动。如图2所示，制备纯水时，净水管路30上的第一阀体320关闭，纯水管路40的第二阀体420打开。原水从进水管20经过进水口110进入到滤芯组件10进行精细过滤得到纯水。经过精细过滤后得到的纯水从纯水出口140流出，并经过纯水管路40流出，由此，经过精细过滤后得到的纯水可以直接饮用。
需要说明的是，在制备纯水的过程中会产生废水，废水可以从净水出口120排出后， 经过排污管路50直接排出过滤水系统100(如图2中箭头：c2→c3所示的流动方向)；部分废水也可以经过循环管路70返回至进水管20中(如图2中箭头：c2→d3→d4所示的流动方向)，并流入至滤芯组件10内再次进行过滤。由此，使废水得到了循环利用，节约了水资源。
根据本发明实施例的过滤水系统100，通过设置滤芯组件10，可以使过滤水系统100结构紧凑，优化管路的布局。而且，在该过滤水系统100中分别设置有净水管路30和纯水管路40，由此，可以根据生活中不同的用水需求选择不同的水质出口，操作方便，而且可以减轻浪费，节能减耗。另外，排污管路50与净水管路30连通，由此，可以使排污管路50与净水管路30共用净水出口120，从而减少了过滤水系统100的接口，进一步优化了管路布局。而且，通过在过滤水系统100上设置循环回路，可以使废水得到循环利用，从而节约了水资源。
根据本发明的一些实施例，如图1和图2所示，过滤水系统100还可以包括：泵体组件60和第二阀体420。其中，泵体组件60设在进水管20上，用于驱动进水管20内水流动的泵体组件60。由此，可以通过泵体组件60可以增加水流压力，有利于提高过滤水系统100的过滤效率。需要说明的是，当需要进行精细过滤时，需要水流达到一定的水压，通过在进水管20上设置泵体组件60，可以增加水流的水压，以使水流流入滤芯组件10进行精细过滤。如图1和图2所示，纯水管路40上设置有第二阀体420。由此，可以通过控制第二阀体420连通过断开纯水管路40。
可选地，泵体组件60位于进水控制阀210与进水口110之间。由此，可以通过控制进水控制阀210及时控制水路的通断。可以理解的是，当进水控制阀210关闭时，可以切断原水流入至泵体组件60和滤芯组件10中；当进水控制阀210打开时，原水可以从进水管20流入到泵体组件60和滤芯组件10中。将泵体组件60设置在进水控制阀210和进水口110之间，可以防止因误操作造成过滤水系统100损坏。例如，若将进水控制阀210设置在泵体组件60的下游，当进水控制阀210关闭而泵体组件60未关闭时，经泵体组件60加压后的水流容易导致管路的崩裂而损坏过滤水系统100。这里所述的“下游”可以是指如图1和图2所示，按照箭头所示的水流方向所理解的下游。
根据本发明的一些实施例，如图2所示，循环管路70的一端连接在进水控制阀210和泵体组件60之间。由此，部分废水可以经过循环管路70返回至过滤水系统100内，并经过泵体组件60增压，再次进入到滤芯组件10进行再次过滤，从而使废水得到循环利用，节约了水资源。
进一步地，泵体组件60可以为增压泵，由此，通过设置增压泵可以为水流提供足 够的水压，以供水流穿过滤芯组件10进行精细过滤。在本发明的一些示例中，如图1和图2所示，第一阀体320和第二阀体420可以为单向阀。需要说明的是，第一阀体320和第二阀体420可以采用单向阀高压开关对过滤水系统100进行反馈控制。如图1和图2所示，在纯水管路40的端部设置有纯水外接口410，纯水外接口410处可以设置纯水外接口开关411；净水管路30的端部可以设置有净水外接口310，净水外接口310处可以设置有净水外接口开关311。第一阀体320和第二阀体420可以设置为单向阀高压开关，单向阀高压开关可以检测单向阀下游的压力变化，并将压力变化信号反馈至系统，系统可以根据反馈信号调整进水控制阀210和泵体组件60的通断。
例如图2所示，当关闭净水外接口开关311，打开纯水外接口开关时411，第二阀体420可以检测到纯水管路40下游水压降低，并将水压降低信号传递给系统，系统控制进水控制阀210和泵体组件60运行，此时，原水可以从进水管20流入到过滤水系统100，并经过泵体组件60进行增压，增压后的水流经过滤芯组件10进行初步过滤和精细过滤，得到纯水并从纯水出口140流入到纯水管路40，最后从纯水外接口410流出。制备纯水过程中产生的废水，部分可以从排污管路50直接排出过滤水系统100(如图2中箭头c2→c3所示的流动方向)；另一部分废水则可以沿循环管路70返回至进水管20中再次进行过滤利用(如图2中箭头：c2→d3→d4所示的流动方向)，从而节约了水资源。
如图1所示，当打开净水外接口开关311时，第一阀体320检测到净水管路30下游水压降低，并将水压降低信号传递给系统，系统根据水压降低信号关闭泵体组件60。此时，从进水管20进入到过滤水系统100中的水流，由于不能经过泵体组件60的增压，水流的水压较低，此时，水流达不到精细过滤所需的水压，水流只能流入到滤芯组件10内进行初步过滤。水流经过初步过滤后得到净水，并从净水口流入到净水管路30中，最后从净水外接口310流出。值得理解的是，当打开净水外接口开关311时，系统控制关闭泵体组件60，过滤水系统100中的水流的压力较低，不能进行精细过滤，因此，此时不会制备纯水，纯水管路40、排污管路50以及循环管路70处于断开状态(如图1中所示的虚线管路)。
可选地，进水控制阀210为电磁阀。通过将进水控制阀210设置为电磁阀，一方面，电磁阀操作精确、可靠，有利于提高过滤水系统100运行的可靠稳定性；另一方面，电磁阀相对于手动阀门，可以减轻打开或这关闭进水控制阀210时的体力劳作，有利于提高过滤水系统100的整体性能。
根据本发明的一些实施例，排污管路50上具有用于控制其通断的第三阀体510。由 此，通过设置第三阀体510可以切断或连通排污管路50，还可以对废水的流量大小进行调节。值得理解的是，通过第三阀体510可以控制废水流量的大小。例如，当通过控制第三阀体510调小废水流量时，可以使水流具有足够的水压进行精细过滤。而当通过控制第三阀体510调大废水流量，并且关闭纯水外接口开关411和净水外接口开关311，此时，如图2所示，过滤水系统100中的水流可以按照图中箭头：a1→c2→c3所示的方向流动。需要说明的是，在精细过滤的过程中，会在精细过滤滤芯处积累杂质，长时间使用后，精细过滤滤芯上的杂质积累较多。由此，通过调大废水管路50流量并关闭纯水外接口开关411和净水外接口开关311，可以对精细过滤滤芯进行冲刷清洗。由此，可以保护精细过滤滤芯，延长精细过滤滤芯的使用寿命。
进一步地，第三阀体510为电磁阀。由此，可以方便精确的控制第三阀体510的通断。需要说明的是，在正常制备净水和纯水时，第三阀体510可以处于不通电状态。当第三阀体510处于不同电状态时，第三阀体510开有小流量通孔，一方面可以维持过滤水系统100制备纯水时所需的水压；另一方面可以排出制备纯水时产生的废水。当需要对精细过滤滤芯进行清洗时，可以对第三阀体510通电，使第三阀体510处于敞开状态，此时，关闭纯水外接口开关411和净水外接口开关311，从而调大废水流量，可以提高废水的流通量，以对精细过滤滤芯进行清洗处理。
在本发明的一些实施例中，如图1和图2所示，过滤水系统100还可以包括前置过滤网220，前置过滤网220设置在进水管20上，且前置过滤网220位于进水控制阀210的上游。这里所述的“上游”是指如图1和图2中箭头所示的水流方向所理解的上游。由此，通过在进水管20的上游设置前置过滤网220，可以使水流经过前置过滤网220时过滤掉水流中的大颗粒杂质，防止大颗粒杂质进入到进水控制阀210和泵体组件60内，对进水控制阀210和泵体组件60造成损坏，从而延长了进水控制阀210和泵体组件60的使用寿命。
可选地，所述循环管路70上设有节流阀710。由此，可以通过节流阀710控制循环管路70中废水流量的大小。例如，当原水的水质较好时，可以调小第三阀体510并调大节流阀710，使循环管路70中的废水流量增大，以提高废水的利用率；当原水的水质较差时，可以调大第三阀体，并调小或关闭节流阀710，使循环管路70中的废水流量减小，以防止杂质过多的废水返回至进水管20中，对泵体组件60和滤芯组件10造成损坏，影响过滤水系统100的正常运行。
在本发明的一些实施例中，滤芯组件10可以包括：前置滤芯、精细过滤滤芯和后置滤芯。其中，前置滤芯位于进水口110和净水出口120之间，前置滤芯可以过滤掉原 水中的大颗粒杂质，得到净水。净水可以作为清洗衣物、浇花等生活用水。精细过滤滤芯位于纯水出口140和净水出口120之间，精细过滤滤芯可以对净水进一步过滤，过滤掉水中的细微杂质，如将过多的无机盐、有机物、重金属离子、细菌、病毒、农药、三氯甲烷废物等其它有害物质统统截留下来，并通过连续排放的废水将这些水中有害异物及盐分排出，进而使水质进一步提高。在纯水出口140处还设置有后置滤芯，经过精细过滤滤芯的水流经后置滤芯进一步过滤。例如，后置滤芯可以使用活性炭，一方面，活性炭可以利用内部大量的纤维空隙，吸附水中的色素和异味等；另一方面还可以在活性炭中添加果味，由此，通过后置滤芯流出后的纯水清洁安全，而且口感得到了改善。
进一步地，精细过滤滤芯可以为反渗透滤芯或纳滤膜滤芯。也就是说，精细过滤滤芯可以选择使用反渗透滤芯，也可以选择使用纳滤膜滤芯。需要说明的是，反渗透滤芯具有极小的孔径，孔径可以达到头发丝的一百万分之一(0.0001微米)，只有水分子及部分矿物离子能够通过，因此可以有效地过滤掉水中的杂质、细菌和病毒等。然而，水流在不受外力的作用下具有从低浓度向高浓度流动的特性。因此，需要对水流施加足够的压力，保证水流穿过反渗透滤芯起到精细过滤的效果。而纳滤膜滤芯纳滤的孔径范围在几个纳米左右，纳滤是一种介于反渗透和超滤之间的压力驱动膜分离过程，采用纳滤膜滤芯可以降低过滤水系统100中精细过滤过程中对水压的要求，从而可以节省能耗。
可以理解的是，进水管20上可以不设置泵体组件60，进水控制阀210可以设置为手动进水控制阀，排污管路50上的第三阀体510设置为手动第三阀体，且净水外接口开关311为净水手动阀，纯水外接口开关411可选为纯水手动阀，从而过滤水系统100在使用过程中，可以不需要泵等用电的设备，只需手动调整手动进水控制阀、手动第三阀体、净水手动阀和纯水手动阀的开闭即可，进而达到省电、降低成本的目的。
例如，当需要获得净水时，可以打开手动进水控制阀、净水手动阀、且使纯水手动阀保持关闭状态，原水经滤芯组件10过滤后从净水出口120流出，并通过净水管路30由净水外接口310流出以供用户使用，此时基本没有废水产生，手动第三阀体可以保持在关闭状态；当需要获得纯水时，可以打开手动进水控制阀、纯水手动阀、手动第三阀体阀、且使净水手动阀保持关闭状态，原水可以依靠自身的压力渗透到精细过滤滤芯内进行过滤，并从纯水出口140流出滤芯组件10，最终通过纯水管路40由纯水外接口410流出以供用户使用，废水通过排污管路50流出。
下面参照图1和图2以两个具体的实施例详细描述根据本发明实施例的过滤水系统 100。值得理解的是，下述描述仅是示例性说明，而不是对本发明的具体限制。
实施例一：
如图1和图2所示，过滤水系统100包括：滤芯组件10、进水管20、纯水管路40、净水管路30、排污管路50和循环管路70。
其中，如图1和图2所示，滤芯组件10包括：进水口110、净水出口120和纯水出口140。滤芯组件10为一体化复合滤芯，且滤芯组件10包括：前置滤芯、精细过滤滤芯和后置滤芯。前置滤芯位于进水口110和净水出口120之间，精细过滤滤芯为反渗透膜滤芯且位于纯水出口140和净水出口120之间，后置滤芯位于纯水出口140处。
进水管20与进水口110连通，进水管20上设置有前置过滤网220、进水控制阀210和泵体组件60，进水控制阀210为电磁阀，泵体组件60为增压泵。前置过滤网220位于进水控制阀210和泵体组件60的上游。净水管路30与净水出口120连通，净水管路30上设置有第一阀体320，净水管路30的端部设置有净水外接口310和净水外接口开关311。纯水管路40与纯水出口140连通，纯水管路40上设置有第二阀体420，纯水管路40的端部设置有纯水外接口410和纯水外接口开关411。第一阀体320和第二阀体420为单向阀。排污管路50的上游连接端连接在第一阀体320和净水出口120之间。循环管路70的上游与排污管路50连通，循环管路70的下游连接在进水控制阀210和泵体组件60之间，循环管路70上设置有节流阀710。
其中，如图1所示，当过滤水系统100制净水时，打开净水外接口开关311，净水管路30部分连通，第二阀体420检测到净水管路30下游的水压降低，并将水压降低信号反馈至系统，系统根据水压降低信号关闭泵体组件60。此时，如图1所示，纯水管路40、排污管路50和循环管路70处于断开状态(如图1中所示纯水管路40、排污管路50和循环管路70为虚线)，水流在过滤水系统100内沿图1所示箭头：a1→a2→a3所示的方向流动。如图1所示，原水进入进水管20时，首先经过前置过滤网220过滤除掉水流中的大颗粒杂质，防止水流中的大颗粒杂质造成进水控制阀210和泵体组件60的损坏。水流从进水管20经过进水口110进入到滤芯组件10内，经过前置滤芯进行初步过滤得到净水，净水经过净水出口120流出滤芯组件10，并经过净水外接口310流出，由此，得到净水可以作为清洗衣物、浇花等生活用水。
当过滤水系统100制纯水时，如图2所示，关闭净水外接口开关311，净水管路30断开(如图2中虚线所示的净水管路30)，并打开纯水外接口开关411，当打开纯水外接口开关411时，第二阀体420检测到纯水管路40下游的水压降低，并将水压降低的信号反馈至系统，系统控制第一阀体320和泵体组件60打开，纯水管路40以及排污管 路50连通。水流在过滤水系统100中沿箭头：a1→b2所示的方向流动。
如图2所示，制备纯水时，原水从进水管20经过前置过滤网220过滤掉原水中的大颗粒杂质。过滤后的水流经过进水控制阀210和泵体组件60从进水口110进入滤芯组件10。其中，泵体组件60可以对水流进行加压，增压后的水流在滤芯组件10内经过精细过滤滤芯进一步过滤，并经后置滤芯再次过滤以进一步改善水质并提高水质口感，最后得到的纯水从纯水出口140流出，并经过纯水管路40流出，由此，得到纯水可以作为饮用水或用以做饭等。
需要说明的是，在制备纯水的过程中会产生废水，废水从净水出口120排出后，部分废水可以经过排污管路50直接排出过滤水系统100(如图2中箭头：c2→c3所示的流动方向)；另一部分废水可以经过循环管路70返回至进水管20中(如图2中箭头：c2→d3→d4所示的流动方向)，并流入至滤芯组件10内再次进行过滤。由此，使废水得到了循环利用，节约了水资源。
由此，通过设置滤芯组件10，可以使过滤水系统100结构紧凑，优化管路的布局。而且，在该过滤水系统100中分别设置有净水管路30和纯水管路40，由此，可以根据生活中不同的用水需求选择不同的水质出口，操作方便，而且可以减轻浪费，节能减耗。另外，排污管路50与净水管路30连通，由此，可以使排污管路50与净水管路30共用净水出口120，从而减少了过滤水系统100的接口，进一步优化了管路布局。而且，通过在过滤水系统100上设置循环回路，可以使废水得到循环利用，从而节约了水资源。
实施例二：
与实施例一不同的是，在该实施例中，进水管路20上的进水控制阀210设置为手动进水控制阀，取消泵体组件60。排污管路50上的第三阀体510设置为手动第三阀体，且净水外接口开关311为净水手动阀，纯水外接口开关411可选为纯水手动阀。
当需要获得净水时，可以打开手动进水控制阀、净水手动阀、且使纯水手动阀保持关闭状态，原水经滤芯组件10过滤后从净水出口120流出，并通过净水管路30由净水外接口310流出以供用户使用，此时基本没有废水产生，手动第三阀体可以保持在关闭状态；当需要获得纯水时，可以打开手动进水控制阀、纯水手动阀、手动第三阀体阀、且使净水手动阀保持关闭状态，原水可以依靠自身的压力渗透到精细过滤滤芯内进行过滤，并从纯水出口140流出滤芯组件10，最终通过纯水管路40由纯水外接口410流出以供用户使用，废水通过排污管路50流出。从而可以达到省电、降低成本的目的。
由此，过滤水系统100在使用过程中，可以不需要泵等用电的设备，只需手动调整 手动进水控制阀、手动第三阀体、净水手动阀和纯水手动阀的开闭即可，进而达到省电、降低成本的目的。在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本发明的实施例，本领域的普通技术人员可以理解：在不脱离本发明的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由权利要求及其等同物限定。
