本申请提出一种复合滤芯，适用于净水设备，以改善现有复合滤芯只具有单个过滤通道、无法满足用户对多种水质的过滤需求的缺陷。
在本申请实施例中，参照图1至图3，该复合滤芯1包括：
壳体10，内设有过滤腔；
隔离组件20，设于所述过滤腔内，将所述过滤腔分隔成相互独立的第一滤腔10a和第二滤腔10b；所述壳体10设有与所述第一滤腔10a相连通的第一进水口111和第一出水口112、以及与所述第二滤腔10b相连通的第二进水口113和第二出水口114；
第一滤芯30，设于所述第一滤腔10a内，且位于所述第一进水口111与所述第一出水口112之间；以及
第二滤芯40，设于所述第二滤腔10b内，且位于所述第二进水口113和所述第二出水口114之间。
具体的，隔离组件20的目的在于将过滤腔划分形成相对独立的第一滤腔10a和第二滤腔10b，其中，第一滤腔10a和第二滤腔10b的分别具有独立的进水水路和出水水路，且互不干扰。壳体10上设置有与第一滤腔10a的进水水路连通的第一进水口111、与第一滤腔10a的出水水路连通的第一出水口112、与第二滤腔10b的进水水路连通的第二进水口113、和与第二滤腔10b的出水水路连通的第二出水口114，其中，第一进水口111、第一出水口112、第二进水口113和第二出水口114在壳体10上的位置可以根据第一滤腔10a和第二滤腔10b的内部结构而定，可分别设置壳体10上任意位置。当然，上述第一进水口111、第一出水口112、第二进水口113和第二出水口114优选是集中设置在壳体10的一端，以便于水路连接，避免净水设备内水路连接管路过于繁杂。
第一滤芯30是设置于第一滤腔10a内，第一滤芯30的两侧分别对应第一进水口111、第一出水口112形成第一滤腔10a的进水水路和出水水路，原水从第一进水口111经过进水水路后通过第一滤芯30的过滤净化，最后经过出水水路从第一出水口112流出净化水。第一滤芯30所采用的芯材一般为碳棒、PP棉或碳纤维复合材料的一种或多种，可以理解的是，有些实施例中为了加强第一滤芯30的过滤效果，上述第一滤芯30还可采用多层芯材相互层叠设置而成，进而使得原水的过滤净化程度。
第二滤芯40是设置于第二滤腔10b内，第二滤芯40的两侧分别对应第二进水口113、第二出水口114形成第二滤腔10b的进水水路和出水水路，原水从第二进水口113经过进水水路后通过第二滤芯40的过滤净化，最后经过出水水路从第二出水口114流出净化水。第二滤芯40所采用的芯材一般为碳棒、PP棉或碳纤维复合材料的一种或多种，可以理解的是，有些实施例中为了加强第二滤芯40的过滤效果，上述第二滤芯40还可采用多层芯材相互层叠设置而成，进而使得原水的过滤净化程度。
本申请技术方案在壳体10内设置分隔组件，使得过滤腔内部形成相互独立的第一滤腔10a和第二滤腔10b，且壳体10上设有与第一滤腔10a连通的第一进水口111和第一出水口112、和与第二滤腔10b连通的第二进水口113和第二出水口114，如此，可使得复合滤芯1具有两个独立的过滤通道，实现对两种水质的分别过滤，满足用户对多种水质的过滤需求；同时，由于本复合滤芯1集成设置了多个过滤通道，降低了净水设备中复合滤芯1的使用个数，一方面，简化了净水设备内部的水路连接，另一方面，也缩减了净水设备内部空间，降低了净水设备的体积，以适应净水设备的轻小型发展趋势。
进一步地，上述的隔离组件20包括设在壳体10内的内桶210，内桶210的外壁面与壳体10的内壁面呈间隔设置，以在内桶210内形成第一滤腔10a，以及在内桶210外形成第二滤腔10b。可以理解的是，上述第一滤芯30是设于内桶210内，上述的第二滤芯40是设与内桶210外。其中，第一滤腔10a和第二滤腔10b的形式结构具有多种多样，以下对本申请中复合滤芯1的结构作出具体阐释。
本实施例中，该壳体10包括外桶120和滤芯接头110，外桶120的上端呈敞口设置，内桶210设置于外桶120内，滤芯接头110密封盖合于外桶120的上端，其中，该滤芯接头110可以与外桶120的上端通过密封插接或焊接等方式连接，即滤芯接头110可拆卸连接于外桶120的上端，或固定连接于外桶120的上端。还有，在本实施例中，内桶210的上端也是与滤芯接头110连接，内桶210的上端设置有开口形成过水通道，进而将第一滤腔10a分别和第一进水口111、第一出水口112连通。
由前文所述，当第一进水口111、第一出水口112、第二进水口113和第二出水口114均设有壳体10的一端时，具有便于水路连接的效果，在本实施例中，第一进水口111、第一出水口112、第二进水口113和第二出水口114均设于滤芯接头110上，如此，便于对复合滤芯1的水路进行连接，缩短了连接水路的距离，避免连接水路盘根错综的设置在净水设备内而带来的极大不便。
在一实施例中，参照图5，上述内桶210的下端呈敞口设置，并且内桶210的下端与外桶120的底壁密封连接，第一滤腔10a位于内桶210内部，第二滤腔10b位于内桶210外部，如此，形成环设于第一滤腔10a外周的第二滤腔10b。需要说明的是，在本实施例中，内桶210的下端也可为密封端，此时，内桶210的下端与外桶120的底壁固定连接即可，如此也能实现第二滤腔10b环设形成于第一滤腔10a外周。在本实施例中，通过第二滤腔10b环设形成于第一滤腔10a外周的结构，使得外桶120的内部结构更加紧凑，降低了复合滤芯1自身的结构复杂程度。
在本申请的一较佳实施例中，参照图1至图3，上述内桶210的下端为敞口端，并与外桶120的底壁呈间隔设置；上述隔离组件20还包括可拆卸地密封固定在内桶210的下端的分隔盘230，第二滤芯40设在所述分隔盘230下方。其中，外桶120沿上下方向的高度大于内桶210的高度，当内桶210的上端与外桶120的上端连接时，则外桶120的底壁会与内桶210的下端具有一定的间距，即呈间隔设置。设置分隔盘230的目的在于：一、将内桶210的下端进行密封，防止内桶210外部的水渗入内桶210内，避免第一滤腔10a和第二滤腔10b的水相互渗漏；二，对内桶210起到支撑作用，防止内桶210下坠，以稳固复合滤芯1的内部结构。
进一步地，在本实施例中，第一滤芯30呈筒状设置，第一滤芯30的上端与内桶210的顶壁之间设有上端盖220，第一滤芯30的两端分别对应与分隔盘230和上端盖220密封贴合，如此，则在第一滤芯30的内外形成第一滤腔10a的进水水路和出水水路。其中，第一滤芯30的内部可以为出水水路，外部为进水水路，反之亦然。在第一滤芯30的两端与上端盖220和分隔盘230密封连接时，通过第一滤芯30的端面分别与上端盖220的下盖面和分隔盘230的上盘面相贴合，进而形成面面贴合密封。为了加强密封效果，也可以在相应的贴合面上设置密封胶或密封涂层，还可以在第一滤芯30与上端盖220或分隔盘230的连接处设置密封胶或密封涂层，以进一步增强密封效果，防止原水从贴合缝隙渗漏、未经过滤直接流出的现象发生。
为了实现第一滤腔10a与第一进水口111和第一出水口112的连接，内桶210的上端设置与第一进水口111连通的内桶接头211，上端盖220与内桶210的顶端之间具有过水通道，第一滤芯30的外部空间通过该过水通道与内桶接头211连通；上端盖220对应内桶接头211的位置设有上盖接头221，上盖接头221穿设于内桶接头211，且上盖接头221的直径小于内桶接头211的直径，上盖接头221连通第一滤芯30的内部空间和第一出水口112。如此，则形成了第一滤芯30的外部为进水水路，第一滤芯30的内部为出水水路，原水从第一进水口111进入至第一滤腔10a，自第一滤芯30的外部过滤渗透至第一滤芯30的内部，随后经过第一出水口112流出净化水，实现第一滤腔10a对原水的过滤净化功能。
进一步地，在本实施例中，上述第二滤芯40呈筒状设置，第二滤芯40的两端分别对应与外桶120的底壁和下端盖130密封贴合；外桶120的内壁与内桶210的外壁之间形成与第二进水口113连通的第一流道101，分隔盘230上设有过流口，用以连通第二滤芯40的外部空间和第一流道101；第二出水口114与第二滤腔10b的内部空间通过导水管140连通。通过上述结构，将第二滤腔10b与位于滤芯接头110的第二进水口113和第二出水口114连通，使得原水通过第二进水口113经第一流道101进入第二滤芯40的外部空间，然后经过第二滤芯40的渗透过滤后通过导水管140将水流引向滤芯接头110，并从滤芯接头110的第二出水口114流出净化水，实现了第二滤腔10b对原水的过滤净化功能。其中，位于分隔盘230的过流口有多种实现方式，例如可以采用在分隔盘230的板面上直接开设通孔形成过流口，也可通过在分隔盘230的外周面设置多个支撑凸起231，参照图4，相邻的支撑凸起231呈间隔设置，当分隔盘230固定于外桶120内时，在相邻的支撑凸起231之间，分隔盘230与外桶120内壁面之间形成供水流通过的过流口。可以理解的是，通过设置支撑凸起231，也可以将分隔盘230固定于外桶120内，为了使分隔盘230与外桶120固定更加稳固，该支撑凸起231沿分隔盘230的的周向均匀排布，则使得分隔盘230上的受力更加均匀，使得产品结构更加稳固。
由于第二滤芯40的内部的出水需要通过导水管140才能流通至第二出水口114，为了使复合滤芯1的整体结构更加紧凑，该导水管140优选沿上下方向穿设于内桶210中，此时，该导水管140密封贯穿分隔盘230。
进一步地，在本实施例中，第二滤芯40的下端与外桶120的底壁之间设有下端盖130，第二滤芯40的两端分别对应与分隔盘230和下端盖130密封贴合，如此，则避免第二滤芯40的下端直接与外桶120的底部贴合，减少了对外桶120底壁的精度要求，有助于降低外桶120的制造难度，降低生产成本。
本申请还提出一种净水设备，该净水设备包括复合滤芯，该复合滤芯的具体结构参照上述实施例，由于本净水设备采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
以上所述仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
