具体实施方式
下面详细描述本公开的实施例，参考附图描述的实施例是示例性的，下面详细描述本公开的实施例。
下面参考图1-图12描述根据本公开实施例的滤芯总成100，滤芯总成100可以应用于净水器1000中，在净水器1000中起到过滤水的作用，从而可以提升水质和口感，净水器1000可以为家用净水器，例如，净水器1000可以用于家庭的厨房中，其可以作为厨下净水器的一种。
结合图2-图5所示，根据本公开实施例的滤芯总成100可以包括第一外壳10、第一滤芯20、第二外壳30、第二滤芯40、第一管路50和第二管路60。第一外壳10为滤芯总成100的整体外壳，其他元件均设置于第一外壳10内，第一外壳10可以起到保护和整体装配在净水主机200上的作用。
具体地，第一滤芯20、第二外壳30和第二滤芯40均设置于第一外壳10内，而且第二滤芯40设置于第二外壳30内，第二外壳30可以起到隔离第一滤芯20和第二滤芯40的作用，这样可以避免第一滤芯20和第二滤芯40的净水水道相互连通，影响净水效果。此种滤芯总成100可以集成有多个滤芯，而且通过共用一个第一外壳10，可以成为一个整体，从而一方面可以方便装配，另一方面可以减小体积，保证净水效果。
另外，第一外壳10位于其他元件的外侧。可以选择在第一外壳10上开设第一滤芯20和第二滤芯40所对应的水口，例如，第一外壳10设置有第一水口11、第二水口12、第三水口13和第四水口14，第一水口11和第二水口12间隔分布，第三水口13和第四水口14间隔分布。净水器1000可以包括水路板，水路板内分布有水路，四个水口可以分别与对应的水路进行连接，从而可以形成净水的循环路径。通过将四个水口间隔设置，可以方便与水路板上的各个水路对应连接，可以避免相关水路过于集中，影响水路板的设计。
其中，四个水口可以设置于第一外壳10的同一端部。例如，第一外壳10的顶部设置有把手盖17，把手盖17上可以对应设置有把手垫18，第一外壳10的底部可以设置有上述的四个水口，如此设置的四个水口可以有利于与相关水路对应连接。把手盖17通过旋熔的方式与第一外壳10连接固定。
如图2和图3所示，第一滤芯20的外周和内周分别设置有第一水道21和第二水道22，第一水道21与第一水口11相连通，而且第二水道22与第二水口12相连通。也就是说，第一滤芯20的外内两侧分别形成有水道，而且水道分别与第一水口11和第二水口12相连通，第一水口11和第二水口12中的一个为第一滤芯20的进水口，第一水口11和第二水口12中的另一个为第一滤芯20的出水口，这样可以保证使用时持续有水通过水道，即第一滤芯20可以持续过滤水。其中，第一水口11可以为进水口，第一水道21可以为进水水道，第二水口12可以为出水口，第二水道22可以为出水水道。
第一滤芯20可以为单滤材滤芯。例如，第一滤芯20可以为碳棒滤芯。又例如，第一滤芯20可以为PP滤芯。再例如，第一滤芯20也可以为多滤材滤芯，例如，第一滤芯20可以为PP绕设在碳棒外周的组合，两层滤材可以外内套设布置，这样可以有效过滤掉水中的杂质，也可以有效过滤水中的有机物、微粒、铁锈、余氯、异味等。第一滤芯20可以为前置滤芯，第二滤芯40可以为后置滤芯，即净水器1000内的水先经过第一滤芯20的过滤，最后再经过第二滤芯40的过滤。
第二外壳30设置于第一滤芯20远离第三水口13和第四水口14的一端，第二滤芯40设置于第 二外壳30内。也就是说，第一滤芯20和第二滤芯40在第一外壳10的长度方向上分布，第一外壳10和第二外壳30可以大体呈圆柱状。通过合理设置第二外壳30和第二滤芯40的位置，可以使得第一滤芯20更靠近第一水口11和第二水口12，可以无需设置管路。
如图3所示，第二外壳30设置有间隔分布的第五水口31和第六水口32，第二滤芯40的外周和内周分别设置有第三水道41和第四水道42，第三水道41与第五水口31相连通，并且第四水道42与第六水口32相连通，第一管路50连接于第三水口13和第五水口31之间，并且设置于第二水道22内，第二管路60连接于第四水口14和第六水口32之间，并且在第二水道22内与第一管路50间隔设置。
具体地，第一管路50可以为进水管路，第二管路60可以为出水管路。通过将第一管路50连接在第三水口13与第五水口31之间，可以使水流从第三水口13进入第一管路50，再通过第一管路50流到第五水口31，由于第三水道41与第五水口31相连通，水流可以通过第一管路50进入第二外壳30中的第三水道41，又由于第三水道41和第四水道42分别设置于第二滤芯40的外周与内周，所以第三水道41可以将水流导向第二滤芯40，水流经过第二滤芯40的过滤处理后进入第四水道42。
进一步地，由于第六水口32与第四水道42相连通，第二管路60连接于第四水口14和第六水口32之间，所以第四水道42中的水流可以从第六水口32进入第二管路60，再通过第二管路60流到第四水口14，然后经过第四水口14流至外界，供用户使用，如此设置，不仅水流流过的通道结构简单直接，可以防止水流流过的通道结构较为复杂，导致水流在通道内的流速较慢，造成停滞，而且水流还不易回流，可以提升滤芯总成100的可靠性。
另外，第二滤芯40可以为碳棒滤芯；或者第二滤芯40也可以为PP滤芯；又或者第二滤芯40也可以为多滤材滤芯，例如，第二滤芯40可以为PP绕设在碳棒外周的组合，两层滤材可以外内套设布置，这样可以有效过滤掉水中的杂质，也可以有效过滤水中的有机物、微粒、铁锈、余氯、异味等。进一步地，第一滤芯20与第二滤芯40可以根据用户对水质的需求选择性地设置，第一滤芯20与第二滤芯40对水的过滤效果可以为递增的关系，即第一滤芯20对水的过滤可以为粗过滤，第二滤芯40对水的过滤可以为精过滤。当用户在进行一些对水质的要求不高的活动，例如洗衣、洗澡等时，净水器1000可以将被第一滤芯20过滤过的水流直接提供给用户使用；相对应地，当用户在进行一些对水质的要求较高的活动，例如饮水，做饭等时，净水器1000可以将先被第一滤芯20粗过滤处理、再被第二滤芯40精过滤处理的水流提供给用户使用。这样不仅可以保证用户的用水健康，而且还可以避免第二滤芯40不必要的使用，这样可以延长第二滤芯40的使用寿命。
另外，在第一滤芯20将水流过滤，并且被过滤后的水流从第二水口12流出后，水流可以进入净水器1000中的增压泵。增压泵可以增大水流的压力，从而可以提升水流的流速，进而可以防止水流在被第二滤芯40过滤处理时流速较小从而导致水流回流、或者水流在滤芯总成100中停滞，这样可以进一步地提升滤芯总成100的可靠性。进一步地，在水流经过增压泵的增压处理后，可以先通过过滤膜的过滤处理后，再进入第二滤芯40，被第二滤芯40过滤处理，这样可以进一步地提升净水器1000的净水效果。所述过滤膜可以为RO反渗透过滤膜，也可以为其他过滤膜，例如纳膜和超滤膜等。
进一步地，结合图3和图5所示，将第一管路50与第二管路60在第二水道22中间隔且并排分布，相较于传统净水器中采用大管套小管、上下错开密封并且需要多次超声波固定的安装方式，这样不仅可以在保证第二水道22中水流通畅的前提下，提升滤芯总成100的空间利用率，而且第一管路50与第二管路60在第二水道22中可以通过打胶来粘接设置，可以使第一管路50与第二管路60的安装简单直接，并且无需其他部件辅助安装，不仅结构较为简单，装配物料少，而且还可以提升净水器1000的生产效率。
由此，通过将第一管路50与第二管路60并排且间隔设置在第二水道22内，不仅可以使第一管路50与第二管路60的结构以及安装简单方便，提升滤芯总成100的装配效率，还可以使滤芯总成100的结构更加紧凑，提升滤芯总成100空间利用率。
结合图8所示，第一管路50的轴线和第二管路60的轴线之间的距离为L1，第三水口13的轴线和第四水口14的轴线之间的距离为L2，L1和L2满足关系式：L1＜L2。具体地，由于第一管路50设置于第三水口13与第五水口31之间，第二管路60设置于第四水口14与第六水口32之间，所以将第一管路50和第二管路60的轴线之间的距离设置得小于第三水口13的轴线和第四水口14的轴线之间的距离，可以在第一管路50的一端与第三水口13相连通、第二管路60的一端与第四水口14相连通的前提下，使第一管路50与第二管路60相对于第三水口13和第四水口14偏心设置，缩短 第一管路50与第二管路60的间隔距离，从而可以使第一管路50与第二管路60在第二水道22中的安装更加紧凑，这样可以进一步地提升滤芯总成100的空间利用率。另外，这样可以使设置第一滤芯20的空间更大，从而可以增大第一滤芯20的体积，进而可以提升第一滤芯20的过滤效果。
结合图8所示，第一管路50的轴线与第三水口13的轴线为非共线关系，相较于第三水口13的轴线，第一管路50的轴线邻近第二管路60的轴线，和/或，第二管路60的轴线与第四水口14的轴线为非共线关系，相较于第四水口14的轴线，第二管路60的轴线邻近第一管路50的轴线。具体地，将第一管路50的轴线设置在第三水口13的轴线的邻近第二管路60轴线的一侧，并且将第二管路60的轴线设置在第四水口14的轴线的邻近第一管路50轴线的一侧。
相较于第一管路50与第二管路60中只有一个向另一个靠近，使第一管路50与第二管路60相互靠近，可以在第一管路50与第二管路60的间隔距离更小、第一管路50与第二管路60相对更加紧凑的情况下，减小第一管路50和第二管路60的轴线分别相对于第三水口13与第四水口14的轴线的偏离程度，这样可以提升第一管路50和第二管路60分别与第三水口13和第四水口14连通的可靠性，从而可以保证水流在从第三水口13进入第一管路50、以及从第二管路60进入第四水口14时的通畅性，进而可以保证水流的压力以及流速，可以进一步地提升滤芯总成100的可靠性。
结合图8所示，第一外壳10在对应第三水口13的位置设置有第一接口15，并且在对应第四水口14的位置设置有第二接口16，第一管路50的一端设置于第一接口15内，并且第二管路60的一端设置于第二接口16内，这样可以使第一管路50与第二管路60的上述一端在第一外壳10上的安装更加稳定牢固，可以防止第一管路50与第二管路60发生移动。由于第一管路50与第二管路60发生移动，不仅导致第一管路50与第二管路60的上述一端分别与第三水口13和第四水口14无法相连通，还会造成滤芯总成100的结构不稳定。因此，通过上述设置，可以保证水流在滤芯总成100中流动的通畅性，可以进一步地提升滤芯总成100的可靠性。
进一步地，结合图8和图9所示，第一接口15的轴线和第二接口16的轴线之间的距离为L1，如此设置，第一接口15的轴线与第一管路50的轴线共线，第二接口16的轴线与第二管路60轴线共线，因此在第一管路50与第二管路60分别安装于第一接口15和第二接口16后，便可以直接实现第一管路50和第二管路60的定位，无需使第一管路50的上述一端和第二管路60的上述一端在第一接口15和第二接口16中再进行位置的调整以实现定位，这样可以使第一管路50的上述一端与第二管路60的上述一端的安装具有一定的防呆效果，从而方便第一管路50和第二管路60的安装。
结合图3所示，第二外壳30在对应第五水口31的位置设置有第三接口33，并且在对应第六水口32的位置设置有第四接口34，第一管路50的另一端设置于第三接口33内，并且第二管路60的另一端设置于第四接口34内。具体地，由于第三接口33与第五水口31的位置相对应，第四接口34与第六水口32的位置相对应，将第一管路50的上述另一端与第二管路60的上述另一端分别安装在第三接口33和第四接口34上，不仅可以保证第一管路50与第二管路60安装的稳定性与可靠性，而且可以提升第一管路50和第二管路60分别与第五水口31和第六水口32连通的可靠性，从而可以保证水流的通畅。
结合图2、图3、图5、图6和图11所示，滤芯总成100还可以主要包括第一端盖70，第一端盖70设置于第一滤芯20的邻近第一水口11和第二水口12的一端，第一端盖70在对应第二水道22的位置设置有第一过孔71和第二过孔72，第一管路50穿设过第一过孔71，并且第二管路60穿设过第二过孔72。具体地，由于第一管路50与第二管路60具有一定的长度，通过在第一端盖70对应第一管路50的上述一端和第二管路60的上述一端的位置开设第一过孔71和第二过孔72，使第一管路50和第二管路60的上述一端分别穿设第一过孔71与第二过孔72后，再分别与第一接口15和第二接口16连接固定，第一过孔71与第二过孔72不仅可以起到定位的作用，可以方便第一管路50与第二管路60的安装，而且还可以起到限位的作用，可以使第一管路50的上述一端与第二管路60的上述一端的安装更加稳定，可以保证第一管路50和第二管路60的上述一端在安装后整体保持平行，防止因第一管路50和第二管路60具有一定高度导致侧歪，这样不仅可以方便后续的装配，而且可以提升滤芯总成100的可靠性。
进一步地，结合图7和图10所示，第一端盖70上还设置有第一定位标识，第一外壳10上设置有与第一定位部位置相对应的第二定位标识，在第一端盖70安装在第一外壳10上时，只需将第一定位标识与第二定位标识设置在同一侧，并且相互对应，便可以保证第一端盖70的设置位置正确，从而可以防止第一端盖70装反，导致第一端盖70上的第一过孔71与第二过孔72分别与第一接口15和第二接口16对应错误，例如第一过孔71与第二接口16相对应以及第二过孔72与第一接口15 相对应，这导致与第一端盖70粘接固定的第一滤芯20的位置错误，进而造成水流无法正常通过第一接口15进入第一滤芯20被过滤处理，以及无法正常从第二接口16流出。通过上述设置，可以进一步地提升滤芯总成100的可靠性。
另外，结合图10所示，第一端盖70上还安装有内管73，内管73的内部中空，并且第一管路50与第二管路60安装于内管73的内部，内管73可以将第一管路50、第二管路60与第一滤芯20隔开，从而不仅可以进一步地提升第一管路50与第二管路60的可靠性，而且还可以保证第一管路50和第二管路60与第一滤芯20以及第二水道22的相对独立性。而且，内管73还可以有效引导第一滤芯20过滤后的水，可以有利于该部分过滤水从内管73在重力作用下快速向下流动。
结合图6所示，第二外壳30朝向第一滤芯20的一端的外周设置有凸出的限位边35，第一滤芯20的端部与第二外壳30的端面固定连接，并且外周配合在限位边35内。具体地，通过将第一滤芯20的端部外周与第二外壳30的限位边35限位配合，可以防止第一滤芯20的端部在第二外壳30的端面上进行径向的移动，这样可以进一步地提升第一滤芯20在滤芯总成100中安装的稳定性与可靠性。
进一步地，第一滤芯20的端部与第二外壳30的端面的连接固定可以使用打胶来进行粘接固定，相较于传统的滤芯总成中在滤芯的两端设置端盖安装固定，如此设置，可以省去在第二外壳30朝向第一滤芯20的一端设置端盖，这样可以在保证第一滤芯20在滤芯总成100中稳定牢固地安装的前提下，不仅进一步地方便第一滤芯20的安装固定，而且还可以降低滤芯总成100的生产成本。另外，第一滤芯20远离第二外壳30的一端与第一端盖70也可以通过打胶安装固定，这样可以进一步地保证第一滤芯20的两端安装的稳定性与牢固性。
进一步地，结合图5所示，第二外壳30中还设置有第二端盖43和第三端盖44，第二端盖43和第三端盖44分别设置于第二滤芯40的两端，并且第二滤芯40的两端可以分别与第二端盖43和第三端盖44通过打胶粘接固定，这样可以保证第二滤芯40在第二外壳30中安装的稳定性与可靠性。
另外，第三端盖44上设置有第三定位部，第二外壳30上设置有第四定位部，第三定位部和第四定位部中的一个为定位凸起，另一个为定位凹槽，通过将定位凸起与定位凹槽进行定位配合，可以使第三端盖44的设置位置准确，第三端盖44上设置有与第三接口33和第四接口34相对应的过孔，这样可以防止将第三端盖44装反，导致与第三端盖44粘接固定的第二滤芯40位置错误，造成水流无法通过第三接口33进入第二滤芯40进行过滤，并且从第四接口34中正常排出。如此设置，可以具有一定的防呆作用，可以使第三端盖44的安装更加方便，可以提升滤芯总成100的可靠性。
进一步地，第三端盖44的外周设置有密封件，由于材质与安装工艺的限制，第三端盖44与第二外壳30之间会存在间隙，密封件可以将第三端盖44与第二外壳30之间的间隙密封，从而可以防止第二外壳30中的水通过第三端盖44与第二外壳30之间的间隙泄漏，这样可以进一步地保证滤芯总成100的可靠性。
结合图5所示，第一管路50与第二管路60结构相同，这样第一管路50与第二管路60可以实现通用，无需将第一管路50与第二管路60分开生产，不仅可以方便第一管路50与第二管路60的制造，而且可以降低生产成本。进一步地，在第一管路50与第二管路60安装的过程中，无需将两者进行区分，可以进一步地提升滤芯总成100的生产效率。进一步地，第一管路50与第二管路60可以为注塑件、也可以为挤压件等，这样可以使第一管路50和第二管路60的生产制造简单方便。另外，第一管路50与第二管路60可以为多组，这样可以提升滤芯总成100的过滤效率。
当然，第一管路50和第二管路60之间还可以连接有连接筋，第一管路50、第二管路60和连接筋为一体成型的结构件，连接筋连接设置在第一管路50与第二管路60之间的间隔空间中，连接筋可以防止第一管路50与第二管路60发生相对的位移，可以保持第一管路50与第二管路60之间的相对平行，从而可以提升滤芯总成100的可靠性。另外，将第一管路50、第二管路60和连接筋设置为一体成型的结构件，不仅可以方便第一管路50、第二管路60和连接筋的生产制造，可以简化生产流程，而且无需在实现第一管路50与第二管路60的安装后，再进行连接筋的安装，不仅可以降低滤芯总成100的装配难度，而且可以提升第一管路50、第二管路60和连接筋之间的连接稳定性。
结合图4所示，第一水口11、第二水口12、第三水口13和第四水口14在第一外壳10的轴向一端间隔设置，第一水口11和第二水口12的间隔方向为第一方向，第三水口13和第四水口14的间隔方向为第二方向，第一方向和第二方向之间具有夹角。具体地，由于滤芯总成100整体呈圆柱形，所以将第一水口11与第二水口12在第一方向上间隔设置，将第三水口13和第四水口14在第二方向上间隔设置，并且使第一方向和第二方向具有夹角，这样可以使滤芯总成100的结构更加紧凑， 可以防止第一水口11、第二水口12、第三水口13和第四水口14在某一方向上共线，导致滤芯总成100在这一方向上的尺寸过大，而且导致其他方向上的空间闲置，造成滤芯总成100的直径增加的同时，还会造成滤芯总成100其他方向上的空间的浪费。由此，这样不仅可以使滤芯总成100的结构更加紧凑，而且可以使滤芯总成100的结构布局更加合理，可以优化滤芯总成100的结构设计。
结合图4所示，夹角可以为90°。将夹角设置成90°，可以使第三水口13与第四水口14相对第一水口11和第二水口12之间的间隔设置更加均匀合理。例如，可以防止第三水口13与第一水口11的间隔距离较长、与第二水口12的间隔较短，导致与第三水口13相对应的水道，由于第三水口13相距第一水口11的距离较长的缘故，尺寸不能过大，从而造成水流流量的减小，并且造成第三水口13由于第二水口12之间较大的间隔空间的浪费。这样可以进一步地使滤芯总成100的结构更加紧凑，而且还可以进一步地使滤芯总成100的结构布局更加合理，可以优化滤芯总成100的结构设计。
结合图3和图6所示，第一管路50的两端分别设置有第一密封圈80，第一密封圈80套设在第一管路50的端部上，并且与第一管路50的端部过盈配合，以及第二管路60的两端分别设置有第二密封圈90，第二密封圈90套设在第二管路60的端部上，并且与第二管路60的端部过盈配合。具体地，由于在第一管路50的两端分别与第一接口15和第三接口33连接固定，以及第二管路60的两端分别与第二接口16和第四接口34连接固定后，第一管路50和第二管路60的两端分别连接在第一接口15与第三接口33之间以及第二接口16与第四接口34之间，由于材质以及安装工艺的限制，并不能实现完全相互贴合紧密，并不能形成完全的密封，这样会造成水从第一管路50和第二管路60流进或流出时，水发生泄露。
因此，通过在第一管路50的两端设置第一密封圈80，并且在第二管路60的两端设置第二密封圈90，可以将第一管路50和第二管路60的两端分别与第一接口15和第三接口33、第二接口16和第四接口34之间形成密封，从而可以防止水的泄露，这样可以进一步地提升滤芯总成100的结构可靠性。
另外，第一密封圈80和第二密封圈90通过过盈配合分别与第一管路50和第二管路60的两端连接固定后，再将第一管路50和第二管路60的两端分别与第一接口15和第三接口33、以及第二接口16和第四接口34过盈配合连接固定，相较于传统的净水器中进出水管的安装固定方式，这样可以在保证第一管路50和第二管路60的安装稳定牢固的前提下，使第一管路50与第二管路60的安装简单方便，不仅可以简化安装的流程，而且无需其他零部件来辅助安装，可以使结构简单，使滤芯总成100更加轻量化。
结合图12所示，第一密封圈80和第二密封圈90均包括套设部81和密封部82，套设部81套设在第一管路50或第二管路60的端部，密封部82设置于套设部81的外周并且在轴向上间隔设置。具体地，套设部81套设在第一管路50或第二管路60的端部，可以保证套设部81与第一管路50和第二管路60的端部的连接稳定性，将密封部82设置于套设部81的外周，可以使密封部82与接口的周壁紧密抵接，从而可以阻断水在第一管路50和第二管路60的两端与接口之间的泄漏流通，这样可以保证第一密封圈80和第二密封圈90的密封性能，从而可以保证第一密封圈80和第二密封圈90的可靠性。
另外，第一密封圈80和第二密封圈90可以为弹性密封圈，并且第一密封圈80和第二密封圈90的内周径小于第一管路50和第二管路60两端的直径，这样可以使第一密封圈80和第二密封圈90分别与第一管路50和第二管路60的连接固定稳定牢固，第一密封圈80和第二密封圈90的外周径大于接口的直径，这样可以使第一密封圈80与第二密封圈90与接口的抵接配合紧密，可以进一步地提升第一密封圈80和第二密封圈90的密封性能。其中，第一密封圈80和第二密封圈90可以为乳胶密封圈、硅胶密封圈和橡胶密封圈中的一种。
结合图12所示，第一密封圈80和第二密封圈90均可以包括翻边83，翻边83设置于套设部81的端部，并且与第一管路50或第二管路60的端面抵接配合。具体地，密封部82与接口的径向的紧密抵接可以使密封部82将第一管路50与第二管路60与接口之间密封，但是第一管路50和第二管路60的两端与各个相对应的水口之间也会存在间隙，也会导致水流的泄露，通过设置翻边83，使翻边83与第一管路50或第二管路60的端面抵接配合，可以使第一管路50和第二管路60的两端与各个相对应的水口的周向被密封，可以保证水从管路全部流向相对应的水口，或从水口流向对应的管路，可以防止水从管路与水口之间的间隙中泄漏，可以进一步地保证滤芯总成100的结构可靠性。
结合图1所示，结合图2-图5所示，根据本公开实施例的净水器1000可以主要包括：净水主机 200和上述滤芯总成100，滤芯总成100设置于净水主机200，被第一滤芯20过滤过的水可以直接从净水主机200中流出，供用户使用，也可以经过净水主机200中的增压泵的增加处理以及RO反渗透膜的过滤处理再进入第二滤芯40进行过滤，然后再从净水主机200中流出供用户使用，这样不仅可以使净水器1000提供给用户不同水质的水，以满足用户进行对水质要求不同的活动时的需求，而且还可以避免第二滤芯40寿命的浪费。另外，净水主机200可以对滤芯总成100起到保护作用，可以防止外力冲击或外界异物损坏到滤芯总成100，可以延长滤芯总成100的使用寿命。
