本申请提出一种复合滤芯，适用于净水设备。
在本申请一实施例中，参照图1至图3，该复合滤芯1包括：
滤芯接头10；
外桶20，所述外桶20的上端与所述滤芯接头10连通；
内桶30，设于所述外桶20内，所述内桶30的上端与所述滤芯接头10连通，所述内桶30的底端呈敞口设置、且与所述外桶20的底壁面之间具有间隔，所述内桶30的外壁面与所述外桶20的内壁面之间有间隙；
分隔盘40，设于所述外桶20内，所述分隔盘40具有相对设置的第一安装面40a和第二安装面40b，所述内桶30的底端与所述第一安装面40a可拆卸地密封连接；
第一滤芯50，呈筒状、且位于所述内桶30内，所述第一滤芯50的下端密封抵接于所述第一安装面40a；以及
第二滤芯60，呈筒状，设于所述外桶20内、且位于所述分隔盘40下方，所述第二滤芯60的上端密封抵接于所述第二安装面40b。
具体的，在复合滤芯1中，外桶20的上端为敞口端，其下端为封闭端，滤芯接头10可拆卸地密封连接于外桶20的上端，进而将外桶20的上端盖310合密封。内桶30的下端为敞口端，其上端设有与滤芯接头10密封连接的内桶接头301，内桶30通过外桶20的上端进入外桶20内部，内桶30的高度小于外桶20的高度，进而使得内桶30的下端与外桶20的底壁面呈间隔设置；内桶30的径向尺寸也小于外桶20的径向尺寸，并且在内桶30的外壁面与外桶20的内壁面之间具有间隙。分隔盘40固定于外桶20内，并且分隔盘40的第一安装面40a将内桶30的下端密封，进而使得内桶30与外桶20形成相对独立的第一滤腔100和第二滤腔200，其中，内桶30内部为第一滤腔100，内桶30外部为第二滤腔200。第一滤芯50设于该第一滤腔100内，此时第一滤芯50呈筒状设置，第一滤芯50的下端密封抵接于分隔盘40的第一安装面40a，使得第一滤芯50的内外两侧相互隔离，第一滤芯50与内桶30的内壁也具有间隙。第二滤芯60设于该第二滤腔200内，且位于分隔盘40的下方，该第二滤芯60的上端密封抵接于分隔盘40的第二安装面40b，使第二滤芯60的内外两侧也相互隔离设置。
值得说明的是，在上述结构中，设置分隔盘40的目的在于：一、将内桶30的下端密封，使得在外桶20内形成相互独立的第一滤腔100和第二滤腔200；二、分隔盘40对内桶30具有支撑作用，可防止内桶30下坠；三、分隔盘40的第一安装面40a与第一滤芯50的下端密封抵接、第二安装面40b与第二滤芯60的上端密封抵接，进而在第一滤腔100内对应第一滤芯50的内外两侧形成第一进水腔101和第一出水腔102、在第二滤腔200内对应第二滤芯60的内外两侧形成第二进水腔201和第二出水腔202，以形成各自对应的过滤通道。
通过上述结构，通过分隔盘40与内桶30的密封配合在外桶20内分别形成了第一滤腔100和第二滤腔200，此时外桶20或滤芯接头10可对应第一滤腔100设置第一进水口110和第一出水口120、对应第二滤腔200设置第二进水口130和第二出水口140，使得本复合滤芯1具备同时过滤两者不同水质的功能，提高了产品的使用性能，增强产品的市场竞争力。当本复合滤芯1应用于净水设备时，可有效减少净水设备内使用的复合滤芯1的数目，因而降低内净水设备内部的空间要求，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。
在本实施例中，第一滤芯50和/或第二滤芯60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50和/或第二滤芯60的过滤效果，上述第一滤芯50和/或第二滤芯60还可采用多层芯材相互层叠设置而成，以提高过滤净化程度。
本申请技术方案通过在外桶20内设置内桶30和分隔盘40，在外桶20内形成两个相互独立的第一滤腔100和第二滤腔200，且第一滤腔100位于内桶30内，第二滤腔200位于内桶30外，分隔盘40上具有的第一安装面40a与第一滤芯50的上端密封抵接，使得第一滤腔100内对应第一滤芯50、第二滤腔200内对应第二滤芯60形成各自独里的过滤通道，进而实现两种水质的单独过滤，以满足用户对多种水质的过滤需求；由于本复合滤芯1集成设置了两个过滤通道，降低了净水设备中复合滤芯1的使用数量，一方面，简化了净水设备内部的水路连接，另一方面，降低了对净水设备内部的空间要求，有利于降低净水设备的体积，以适应净水设备的轻小型发展趋势。
进一步地，在本实施例中，参照图4至图7，上述分隔盘40的第一安装面40a上对应内桶30的底端设置第一环形密封槽410，内桶30的底端插接于第一环形密封槽410内，此时通过密封插接的方式，既实现了内桶30与分隔盘40的可拆卸连接，又实现了分隔盘40密封内桶30的下端的效果。可选地，该第一环形密封槽410内可设置密封胶或密封涂层来进一步降低第一环形密封槽410与内桶30的桶壁之间的装配间隙，以达到更佳的密封效果。当然，本申请不限于此，于其他实施例中，内桶30的下端也可通过焊接方式与分隔盘40实现密封连接。
当第一滤芯50设置在内桶30中时，第一滤芯50的下端面与分隔盘40上的第一安装面40a密封抵接，由于第一滤芯50的直径小于内桶30的直径，第一滤芯50存在沿第一安装面40a移动错位的现象，进而影响第一滤芯50与第一安装面40a之间的密封性。为了避免出现上述问题，在本实施例中，需要对第一滤芯50在第一安装面40a的位置进行限位以防止第一滤芯50的移动，其中，第一安装面40a对应第一滤芯50设有第一环形凸缘420，该第一环形凸缘420的内侧面与第一滤芯50的外周面抵接，进而使得第一滤芯50受到第一环形凸缘420的限制，进而不会在发生偏移错位，进而保证了第一滤芯50与分隔盘40之间的密封性。需要说明的是，在本实施例中，为了保障第一滤芯50与分隔盘40之间的密封性，该第一滤芯50下端的端面优选与第一安装面40a是贴合的，通过面面贴合的方式增强密封效果。当第一滤芯50插设于第一限位槽420a内时，第一环形凸缘420的内周面也优选与第一滤芯50的外周面相贴合，以进一步增强密封效果。当然，在本实施例中，还可以通过在第一滤芯50与第一安装面40a之间设置密封胶或密封涂层来进一步降低装配间隙，以实现更佳的密封效果。
进一步地，上述第一环形密封槽410可设于第一环形凸缘420的上端面上，进而使得在增加分隔盘40的厚度的前提下，增大第一环形密封槽410的槽深，使得内桶30与分隔盘40密封效果更佳。同时，第一滤芯50的外周面与内桶30的内壁之间具有间隙，以利于在第一滤腔100内形成水路。
需要指出的是，在本实施例中，与第一滤腔100相对应的第一进水口110和第二进水口130是设置在位于外桶20上端的滤芯接头10上，由于内桶30上端的内桶接头301与滤芯接头10相连通，此时，在第一滤芯50与内桶30的上端之间还设置有上端盖310，该第一滤芯50的上端也与上端盖310密封抵接。在内桶30中，第一滤芯50的两端分别与上端盖310和分隔盘40密封，使第一滤芯50的内外相互隔离，形成了第一进水腔101和第二出水腔202。其中，上端盖310上还开设有上盖接头311，该上盖接头311也与滤芯接头10相连通，且上盖接头311间隔设置于内桶接头301内，上端盖310的上侧面与内桶30顶端的内侧面也具有过水通道。该第一进水口110与上盖接头311相连通，进而将进水导向至第一滤芯50外部的第一进水腔101内，该上盖接头311与第一出水口120连通，进而将第一滤芯50内部的第一出水腔102的水流导向第一出水口120，实现第一滤腔100对水质的过滤净化。
在第二滤腔200内，由于第二滤芯60设于分隔盘40的下方，且第二滤芯60的上端与第二安装面40b密封抵接，为了防止第二滤芯60沿第二安装面40b发生偏移错位，影响第二滤芯60与分隔盘40之间的密封效果，在本实施例中，需要对第二滤芯60在第二安装面40b的位置进行限位以防止第二滤芯60的移动，其中，第二安装面40b对应第二滤芯60设有第二环形凸缘430，该第二环形凸缘430的内侧面与第二滤芯60的外周面抵接。由于第二滤芯60受到第二环形凸缘430的限制，进而不会在发生偏移错位，进而保证了第二滤芯60与分隔盘40之间的密封性。需要说明的是，在本实施例中，为了保障第二滤芯60与分隔盘40之间的密封性，该第二滤芯60上端的端面优选与第二安装面40b是贴合的，通过面面贴合的方式增强密封效果。第二环形凸缘430的内周面也优选与第二滤芯60的外周面相贴合，以进一步增强密封效果。当然，在本实施例中，还可以通过在第二滤芯60与第二安装面40b之间设置密封胶或密封涂层来进一步降低装配间隙，以实现更佳的密封效果。
在本实施例中，第二进水口130和第二出水口140，也优选设置于滤芯接头10，此时，第一进水口110、第一出水口120、第二进水口130和第二出水口140均设于滤芯接头10，也即四者均设于复合滤芯1的一端，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。
为了实现上述目的，在本实施例中，需要将第二滤腔200与滤芯接头10的第二进水口130和第二出水口140相连通。在第二滤腔200内，第二滤芯60的外侧形成第二进水腔201，第二滤腔200的内部形成第二出水腔202，外桶20与内桶30之间的间隙形成第二进水腔201的进水通道203，滤芯接头10的第二进水口130与该进水通道203连通，分隔盘40上对应该进水通道203的位置开设有过流口440a，将水流导向第二进水腔201，水流自第二滤腔200的外部进入第二滤腔200的内部进行过滤净化，最后通过导水管将第二出水腔202内的水导向第二出水口140。
需要说明的是，在第二滤腔200内，为了使水流全部通过第二滤芯60实现过滤净化，避免水流自第二滤芯60的下端流向第二出水腔202，本实施例中，第二滤芯60的下端也与外桶20的底壁密封抵接。作为优选实施方案，第二滤芯60的下端与外桶20的底壁之间设有下端盖210，第二滤芯60的两端分别对应与第二安装面40b和下端盖210密封贴合，如此，则避免第二滤芯60的下端直接与外桶20的底部贴合，减少了对外桶20底壁的精度要求，有助于降低外桶20的制造难度，降低生产成本。
可以理解的是，在上述实施例中，分隔盘40上设置有过流口以实现第二进水口130与第二进水腔201的连通。其中，该过流口的形成方式有多，例如直接在分隔盘40上开设通孔来形成，或者通过设置支撑凸起440的方式来形成。参照图4至图7，分隔盘40的外周面上设有多个支撑凸起440，支撑凸起440与外桶20的内壁抵接，相邻支撑凸起440之间形成过流口，如此，则过流口将分隔盘40两侧的过滤腔连通，即连通进水通道203与第二进水腔201。需要说明的是，支撑凸起440还具有将分隔盘40固定于外桶20的内壁的作用，支撑凸起440远离分隔盘40的一端与外桶20内壁抵接，进而将分隔盘40卡持固定于外桶20内。为了使分隔盘40与外桶20固定更加稳固，该支撑凸起440沿分隔盘40的的周向均匀排布，则使得分隔盘40上的受力更加均匀，以使分隔盘40更好地支撑内桶30。
由于第二滤芯60的内部的出水需要通过导水管才能流通至第二出水口140，为了使复合滤芯1的整体结构更加紧凑，该导水管优选沿竖直方向穿设于内桶30中，此时，该导水管为中心管70，该中心管70也沿上下方向密封穿设分隔盘40，以连通第二滤芯60的内部空间和所述滤芯接头10，实现将第二出水腔202与第二出水口140导通，将过滤净化后的水导出第二滤腔200。参照图4，在本实施例中，分隔盘40上对应中心管70开设有过孔460，第一安装面40a及/或第二安装面40b上围绕过孔460设有第三环形凸缘450，第三环形凸缘与中心管70管壁之间形成第二环形密封槽450a，所述第一滤芯50的内壁与中心管70的管壁之间设有密封圈80，通过密封圈80分别与中心管70和第二环形密封槽450a的槽壁的密封抵接，进而可实现中心管70径向和轴向的密封。
参照图1和图4，为了防止第二环形密封槽450a内密封圈80沿中心管70的轴向移动脱离第二环形密封槽450a，该第二环形密封槽450a的槽口设有密封盖90，密封盖90对应中心管70设有避让孔91，密封盖90盖合与第二环形密封槽450a的槽口，以保证密封圈80的可靠工作，保障密封效果。
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。
