下面参考图1描述根据本发明实施例的过滤水系统100。
如图1所示，根据本发明实施例的过滤水系统100，包括原水进水口100a、纯水出水口100b、净水出水口100c、废水出水口100d以及一体化滤芯1。
一体化滤芯1包括前置滤芯、精细过滤滤芯和后置滤芯，一体化滤芯1具有第一接口10a、第二接口10b、第三接口10c和第四接口10d，第一接口10a与原水进水口100a相连，第二接口10b与纯水出水口100b相连，净水出水口100c和废水出水口100d均与第三接口10c相连，从原水进水口100a进入的原水依次经前置滤芯、精细过滤滤芯和后置滤芯过滤后适于从纯水出水口100b流出，从原水进水口100a进入的原水仅经前置滤芯过滤后适于从净水出水口100c流出，其中与纯水出水口100b相连的流路和第四接口10d中的至少一个上设有蓄水装置2。
这里，需要说明的是，原水依次经过一体化滤芯1的前置滤芯、精细过滤滤芯和后置滤芯过滤后得到的水为“纯水”，纯水可直接饮用；而原水只经过一体化滤芯1的前置滤芯过滤后得到的水为“净水”，净水可以作为生活用水，如洗衣、冲马桶等。
例如，如图1所示，过滤水系统100可以进一步包括原水流路101、纯水流路102、 净水流路103、废水流路104和蓄水流路105，具体而言，一体化滤芯1的第一接口10a通过原水流路101与原水进水口100a相连，一体化滤芯1的第二接口10b通过纯水流路102与纯水出水口100b相连，一体化滤芯1的第三接口10c通过净水流路103与净水出水口100c相连，且第三接口10c通过废水流路104与废水出水口100d相连，其中，蓄水装置2设在蓄水流路105上，且蓄水装置2通过蓄水流路105与一体化滤芯1的第四接口10d相连。进一步地，纯水出水口100b处可以设有纯水阀9以实现纯水出水口100b的开闭，同样地，净水出水口100c处可以设有净水阀10以实现净水出水口100c的开闭，废水流路104上可以设有废水阀以实现废水出水口100d的开闭。可选地，废水阀可以为废水电磁阀8，废水电磁阀8处于常断电状态，此时废水电磁阀8内形成有小孔以保证废水流路104的流通，同时保持一体化滤芯1内精细过滤滤芯前的进水压力。可以理解的是，废水电磁阀8的具体结构和工作原理等已为本领域的技术人员所熟知，在此不再赘述。
当需要获得纯水时，可以打开纯水阀9、且使净水阀10保持在关闭状态，原水由原水进水口100a通过原水流路101经第一接口10a流入一体化滤芯1中，并依次经过前置滤芯、精细过滤滤芯和后置滤芯的过滤后得到纯水，纯水从第二接口10b流出一体化滤芯1，并通过纯水流路102由纯水出水口100b流出，以便用户使用，纯水可以直接作为饮用水。在此过程中，产生的废水从第三接口10c流出一体化滤芯1，并通过废水流路104由废水出水口100d流出。其中，前置滤芯可以对由第一接口10a进入的原水进行初步过滤，例如，前置滤芯可以有效去除水中的铁锈、泥沙、胶体、吸附水中的余氯及部分有机物等。精细过滤滤芯可以对经前置滤芯初步过滤后的水进行精细过滤，例如精细过滤滤芯可以有效去除水中的细菌、病毒和重金属离子等。后置滤芯可以对经精细过滤滤芯精细过滤后的水进行进一步过滤，例如后置滤芯可以有效去除残余余氯和有机物，改善水的口感。
当需要获得净水时，可以打开净水阀10、且使纯水阀9保持在关闭状态，原水由原水进水口100a通过原水流路101经第一接口10a流入一体化滤芯1中，并经过前置滤芯的过滤后得到净水，净水从第三接口10c流出一体化滤芯1，并通过净水流路103由净水出水口100c流出，净水可以作为用户的日常生活用水，例如洗衣用水等。在此过程中，有少量的废水或基本没有废水产生。
由上述可知，过滤水系统100可以得到纯水和净水两种不同水质的水，以用作不同的用途，从而可以使水资源得到充分利用，提高了水资源的利用率，且实现了节约用水。
当需要大量用水时，可以预先在蓄水装置2内储存一定量的水。具体而言，可以关 闭纯水阀9、同时关闭净水阀10，原水由原水进水口100a通过原水流路101经第一接口10a流入一体化滤芯1中，并依次经过前置滤芯、精细过滤滤芯的过滤后从第四接口10d流出一体化滤芯1，并通过蓄水流路105流入蓄水装置2内进行储存，直至蓄水装置2内水满为止。在此过程中，产生的废水同样可以从第三接口10c流出一体化滤芯1，并通过废水流路104由废水出水口100d流出。由于蓄水装置2的设置，当打开纯水阀9、且净水阀10保持在关闭状态时，蓄水装置2可以通过压力例如用户或其他装置对蓄水装置2内的水施加压力、或其他动力将蓄水装置2内的水通过蓄水流路105由第四接口10d重新送入一体化滤芯1内，经过后置滤芯的过滤成为纯水，并通过纯水流路102从纯水出水口100b流出，从而满足了用户的大量使用水的需求。
当然，本发明不限于此，第四接口10d处的蓄水流路105以及纯水流路102上可以分别设有蓄水装置2(图未示出)，以进一步满足用户大量使用水的需求。或者，过滤水系统100还可以不包括蓄水流路105，此时可以将蓄水装置2设置在纯水流路102上(图未示出)，此时同样可以很好地满足用户大量使用水的需求，且过滤水系统100的零部件相对较少，减小了整个过滤水系统100的占用空间，且节约了成本。
根据本发明实施例的过滤水系统100，通过在过滤水系统100的与纯水出水口100b相连的流路和第四接口10d中的至少一个上设置蓄水装置2，可以满足用户大量用水的需求。而且，通过在一体化滤芯1上设置第一接口10a、第二接口10b和第三接口10c，并将第一接口10a与过滤水系统100的原水进水口100a相连，第二接口10b与纯水出水口100b相连，净水出水口100c和废水出水口100d均与第三接口10c相连，从而使得过滤水系统100可以得到纯水和净水两种不同水质的水，以用作不同的用途，水资源可以得到充分利用，提高了水资源的利用率，实现了节约用水。此外，通过采用前置滤芯、精细过滤滤芯和后置滤芯复合构成的一体化滤芯1，一体化滤芯1为一体结构，方便了一体化滤芯1的更换，且减小了一体化滤芯1的体积，同时简化了过滤水系统100的流路连接，从而提高了过滤水系统100的适用性。
在本发明的一些实施例中，第一接口10a与原水进水口100a之间设有进水阀3和增压泵4，进水阀3位于增压泵4的上游。这里，需要说明的是，“上游”可以理解为水的流动方向上的上游。例如，如图1所示，进水阀3和增压泵4可以间隔设置在原水流路101上，进水阀3用于控制原水流路101的导通与隔断，当进水阀3打开时，原水可以通过原水流路101流入一体化滤芯1内进行过滤；当进水阀3关闭时，原水则无法流入一体化滤芯1内。增压泵4用于增大原水的压力，以保证经前置滤芯过滤后的净水可以渗透到精细过滤滤芯内进行过滤。具体而言，当进水阀3打开、且增压泵4工作时， 流向一体化滤芯1的原水的压力较大，使得经前置滤芯过滤后的净水可以顺利地渗透到精细过滤滤芯内进行过滤，此时得到的纯水可以由第二接口10b经纯水流路102从纯水出水口100b流出。当进水阀3打开、且增压泵4停止工作时，此时只能得到净水，得到的净水可以由第三接口10c经净水流路103从净水出水口100c流出。由此，过滤水系统100可以得到纯水和净水两种不同水质的水，从而提高了水资源的利用率。其中，进水阀3可选为电磁阀，但不限于此。
可以理解的是，第一接口10a与原水进水口100a之间可以不设置进水阀3、且不设置增压泵4，此时需要在废水流路104上设置废水阀，废水阀可选为废水手动阀，且净水阀10可选为净水手动阀，纯水阀9可选为纯水手动阀，从而过滤水系统100在使用过程中，可以不需要增压泵4等用电的设备，只需调整净水手动阀、纯水手动阀和废水手动阀的开闭即可，进而达到省电、降低成本的目的。具体而言，当需要获得净水时，可以打开净水手动阀、且使纯水手动阀保持在关闭状态，原水通过原水流路101经第一接口10a流入一体化滤芯1中进行过滤，过滤后得到的净水从第三接口10c流出，并通过净水流路103由净水出水口100c流出以供用户使用，此时基本没有废水产生，废水手动阀可以保持在关闭状态；当需要获得纯水时，可以打开纯水手动阀、打开废水手动阀、且使净水手动阀保持在关闭状态，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，并从第二接口10b流出一体化滤芯1，最终通过纯水流路102由纯水出水口100b流出以供用户使用，废水通过废水流路104由废水出水口100d流出。
同样，第一接口10a与原水进水口100a之间还可以仅设置进水阀3、不设置增压泵4，进水阀3可选为进水手动阀，且净水阀10可选为净水手动阀，纯水阀9可选为纯水手动阀，从而过滤水系统100在使用过程中，可以不需要增压泵4等用电的设备，只需调整净水手动阀、纯水手动阀和进水手动阀的开闭即可，进而达到省电、降低成本的目的。具体而言，当需要获得净水时，可以打开进水手动阀、打开净水手动阀、且使纯水手动阀保持在关闭状态，原水通过原水流路101经第一接口10a流入一体化滤芯1中进行过滤，过滤后得到的净水从第三接口10c流出，并通过净水流路103由净水出水口100c流出以供用户使用，此时基本没有废水产生；当需要获得纯水时，可以打开进水手动阀、打开纯水手动阀、且使净水手动阀保持在关闭状态，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，并从第二接口10b流出一体化滤芯1，最终通过纯水流路102由纯水出水口100b流出以供用户使用，废水通过废水流路104由废水出水口100d流出。但不限于此。
进一步地，蓄水装置2上设有检测装置(图未示出)，当检测装置检测到蓄水装置 2内的液体不满时，过滤水系统100的控制器(图未示出)控制进水阀3打开且增压泵4工作。由此，通过在蓄水装置2上设置可以检测蓄水装置2内的液体是否装满的检测装置，可以实现过滤水系统100的自动蓄水功能，从而满足供水需求。
例如，如图1所示，关闭纯水阀9、关闭净水阀10，检测装置可以实时检测蓄水装置2内储存的水是否已装满蓄水装置2。当检测装置检测到蓄水装置2内的水不满时，检测装置将该信号传递给控制器，控制器控制进水阀3打开、增压泵4启动，原水可以流入一体化滤芯1内，并依次经过前置滤芯、精细过滤滤芯的过滤后从第四接口10d流出一体化滤芯1，最终通过蓄水流路105流入蓄水装置2内进行储存，直至将蓄水装置2装满。当检测装置检测到蓄水装置2内的水已满时，将该信号传递给控制器，控制器控制进水阀3关闭、增压泵4停止工作。
可选地，检测装置为压力传感器或液位传感器等。压力传感器可以用于检测蓄水装置2内的液体的压力，液位传感器可以用于检测蓄水装置2内的液体的液位，使得过滤水系统100更加智能化，极大地方便了用户。
当检测装置为压力传感器时，在压力传感器检测到的压力小于其设定值(例如，可以将蓄水装置2内液体已满时，液体的压力作为设定值)时，控制器控制进水阀3打开、增压泵4启动，原水经过前置滤芯、精细过滤滤芯的过滤后流入蓄水装置2内，直至蓄水装置2水满为止，此时压力传感器检测到的压力达到其设定值，控制器控制进水阀3关闭、增压泵4停止运转。
当检测装置为液位传感器时，在液位传感器检测到的液位小于其预设值(例如，可以将蓄水装置2内液体已满时，液体的液位作为预设值)时，控制器控制进水阀3打开、增压泵4启动，原水经过前置滤芯、精细过滤滤芯的过滤后流入蓄水装置2内，蓄水装置2内的水量逐渐增加，直至蓄水装置2水满为止，此时液位传感器检测到的液位达到其预设值，控制器控制进水阀3关闭、增压泵4停止运转。
可以理解的是，蓄水装置2上还可以不设置检测装置，例如，蓄水装置2可以是透明的，用户可以直接目测蓄水装置2内的水位。当用户观察到蓄水装置2内的液体不满、水位较低时，可以打开上述进水手动阀、且使纯水手动阀和净水手动阀均保持在关闭状态，实现蓄水装置2的蓄水功能。但不限于此。由此，过滤水系统100在使用过程中，蓄水装置2的蓄水量的检测也可以不需要压力传感器、液位传感器等用电的检测装置，进一步省电、降低成本。
在本发明的进一步实施例中，如图1所示，原水进水口100a和进水阀3之间设有前置过滤网5，前置过滤网5可以过滤原水中的肉眼可见物，例如，铁锈等大颗粒杂质 等，从而可以避免原水流路101的堵塞，而且可以避免原水中的杂质等对进水阀3和增压泵4的磨损，以保护进水阀3和增压泵4。
在本发明的一些实施例中，第三接口10c包括彼此独立的第一子接口和第二子接口(图未示出)，净水出水口100c与第一子接口相连且废水出水口100d与第二子接口相连。此时净水出水口100c通过净水流路103与第一子接口相连，废水出水口100d通过废水流路104与第二子接口相连，净水流路103和废水流路104为彼此独立的两个流路，由于第一子接口和第二子接口彼此独立，经前置滤芯过滤后的净水可以全部从净水出水口100c流出，没有废水流出，从而进一步提高了水资源的利用率。当然，净水流路103和废水流路104还可以共用部分流路，例如在图1的示例中，净水流路103和废水流路104可以采用三通管的形式相连，该三通管的一端与第三接口10c相连、另外两端分别与净水出水口100c和废水出水口100d相连，这样可以减少管路接头，简化了过滤水系统100的水路，提高了过滤水系统100的可靠性。
在本发明的一些实施例中，第二接口10b与纯水出水口100b之间设有第一单向阀和第一高压开关，第一单向阀和第一高压开关集成为一体，第三接口10c与净水出水口100c之间设有第二单向阀和第二高压开关，第二单向阀和第二高压开关集成为一体。第一单向阀可以防止纯水流路102内的纯水回流入一体化滤芯1内，第二单向阀可以防止净水流路103内的净水回流入一体化滤芯1内，第一高压开关和第二高压开关可以对其所在位置处的压力进行检测，并将检测信号传递给控制器，控制器控制进水阀3和增压泵4的运作，从而实现对进水阀3和增压泵4的反馈控制。
例如，在图1的示例中，第二接口10b与纯水出水口100b之间的第一单向阀和第一高压开关集成为第一单向阀高压开关6，第三接口10c与净水出水口100c之间设有第二单向阀高压开关7，且第二单向阀高压开关7由第二单向阀和第二高压开关集成。由此，通过将第一单向阀和第一高压开关集成为一体结构，将第二单向阀和第二高压开关集成为一体结构，减少了过滤水系统100的零部件，从而简化了过滤水系统100。
当需要获得纯水时，可以打开纯水阀9、且使净水阀10保持在关闭状态，第一高压开关可以检测到其所在位置处的压力小于其设定压力p1，其中设定压力p1可以满足0.2MPa≤p1≤0.25MPa，并将信号传递给控制器，控制器控制进水阀3打开、增压泵4工作，原水由原水进水口100a通过原水流路101经第一接口10a流入一体化滤芯1中，并依次经过一体化滤芯1的过滤后得到纯水，纯水最终由纯水出水口100b流出，以便用户直接饮用。然后，关闭纯水阀9，由于第一单向阀的反向水流限制，第一高压开关所在位置处的压力逐渐增大，当上述压力达到设定压力p1时，第一高压开关将信号传 递给控制器，控制器控制进水阀3关闭、增压泵4停止工作。可以理解的是，第一高压开关的设定压力p1可以根据实际情况设置，以更好地满足用户的需求。
当需要获得净水时，可以打开净水阀10、且使纯水阀9保持在关闭状态，第二高压开关可以检测到其所在位置处的压力小于其设定压力p2，其中设定压力p2可以满足0.2MPa≤p2≤0.25MPa，并将信号传递给控制器，控制器控制进水阀3打开、增压泵4停止工作，原水由原水进水口100a通过原水流路101经第一接口10a流入一体化滤芯1中，并依次经过一体化滤芯1的前置滤芯的过滤后得到净水，净水最终由净水出水口100c流出，以便用户使用。此时，即使打开纯水阀9，也不会有纯水从纯水出水口100b流出。然后，关闭净水阀10，由于第二单向阀的反向水流限制，第二高压开关所在位置处的压力逐渐增大，当上述压力达到设定压力p2时，第二高压开关将信号传递给控制器，控制器控制进水阀3关闭、增压泵4停止工作。可以理解的是，第二高压开关的设定压力p2可以根据实际情况设置，以更好地满足用户的需求。
当然，在本发明的另一些实施例中，第一单向阀和第一高压开关还可以彼此独立设置，第二单向阀和第二高压开关也可以彼此独立设置(图未示出)。可以理解的是，第二接口10b与纯水出水口100b之间还可以仅设置第一单向阀、不设置第一高压开关，第三接口10c与净水出水口100c之间还可以仅设置第二单向阀、不设置第二高压开关，以进一步简化过滤水系统100的结构，降低成本。
可选地，蓄水装置2为蓄水袋、压力罐或水箱等。其中，蓄水袋或压力罐可以与第四接口10d相连，水箱可以设在纯水流路102上，从而可以满足用户的大量使用水的需求。蓄水袋可折叠、易存放、体积小，且可以根据用户的要求定制各种规格的蓄水袋，以更好地满足用户的需求。压力罐安全可靠，具有良好的经济性，且压力罐可以利用罐内空气的可压缩性来调节和储存水量。水箱对水质无污染，保证了水质的清洁卫生，且水箱的强度较高、重量轻，外形整洁、美观，便于清洗。
可选地，精细过滤滤芯为反渗透滤芯或纳滤膜滤芯等。由于反渗透膜可以过滤掉水中的细菌、病毒、重金属离子等，从而反渗透滤芯可以使得透过反渗透膜的水与无法透过的浓缩水严格区分开来。而纳滤膜可以去除水中的有机物和色度，部分去除溶解性盐，脱除水的硬度，且纳滤膜滤芯同样可以使透过纳滤膜的水与无法透过的浓缩水严格区分开来。由此，无论是采用反渗透滤芯还是纳滤膜滤芯，均可以使精细过滤滤芯的过滤精度较高，透过精细过滤滤芯的水的水质较好，从而保证了纯水的水质，保证了用户的健康。
当过滤水系统100使用一段时间后，需要对一体化滤芯1进行清洗，此时可以关闭 纯水阀9和净水阀10，控制器控制进水阀3打开、增压泵4工作、废水电磁阀8通电，此时废水电磁阀8呈全开状态，原水从第一接口10a流入一体化滤芯1内，并对一体化滤芯1进行冲洗，这样可以去除附着在一体化滤芯1的前置滤芯、精细过滤滤芯上的杂质，使得一体化滤芯1可以继续使用，从而延长了一体化滤芯1的使用寿命。
当然，当过滤水系统100中不设置增压泵4、检测装置、第一高压开关和第二高压开关等用电的设备时，也就是说，无需为过滤水系统100提供电能，过滤水系统100也可以正常运行。例如，进水阀3为进水手动阀，纯水阀9为纯水手动阀，净水阀10为净水手动阀，废水阀为废水手动阀。此时，对一体化滤芯1进行清洗时，可以关闭纯水手动阀和净水手动阀，打开进水手动阀和废水手动阀，此时废水手动阀呈全开状态，原水从第一接口10a流入一体化滤芯1内依次对前置滤芯和精细过滤滤芯进行冲洗，同样可以延长一体化滤芯1的寿命。
