实施例一
本实施例提供一种净化滤芯，如图1-图3所示，包括敞口的壳体1，壳体1内靠近底部的位置可拆卸式固设有杀菌盒2，杀菌盒2包括第一盒体21和第一过滤网22，第一盒体21底部设有供水流过的第一通孔，且第一盒体21内填充有溴代聚苯乙烯海因，第一盒体21与壳体1内部形状相匹配，第一过滤网22与第一盒体21可拆卸式匹配连接；杀菌盒2的第一盒体21的底部与壳体1的底部之间留有间隙，壳体1的底部开设有限流孔11；壳体1内自第一过滤网22到敞口处依次设有阴阳树脂过滤区3和活性炭过滤区4。
本实施例提供的净化滤芯，包括用于容纳过滤材料的壳体1；用于除去自来水中细菌、病毒和藻类菌的杀菌盒2；用于除去自来水中余氯、有机物、铁锈、胶体和泥沙的活性炭过滤区4；用于除去自来水中盐类物质(金属离子)的阴阳树脂过滤区3。初始时，在第一盒体21内装入溴代聚苯乙烯海因，并将第一过滤网22安装在第一盒体21上，第一过滤网22和第一盒体21共同组成封闭式的容纳腔，用于容纳杀菌材料溴代聚苯乙烯海因，其中，第一盒体21镶嵌于壳体1内部，且位置固定。
净水时，将自来水从壳体1的敞口处倒入，自来水在重力的作用下向下流动，首先经过活性炭过滤区4，活性炭过滤区4将自来水中的余氯、有机物、铁锈、胶体和泥沙吸附过滤掉，具体的，活性炭可以为20～30目，点吸附值大于1000；剩下的自来水穿过活性炭过滤区4进入阴阳树脂过滤区3，阴阳树脂过滤区3的阴阳树脂由阴离子树脂和阳离子树脂按照一定比例均匀混合而成，阴阳树脂与自来水中的盐类离子进行反应，将盐类离子去除掉，使得净化后的纯净水的TDS值为“0”；除去盐类离子的自来水继续向下流动到达杀菌盒2，自来水穿过第一过滤网22进入杀菌盒2内，与溴代聚苯乙烯海因接触，溴代聚苯乙烯海因将自来水中的细菌、病毒等微生物杀死；除去微生物的自来水穿过第一盒体21底部的第一通孔继续向下流动，到达壳体1底部并从限流孔11流出壳体1，完成净化滤芯对自来水的净化。
自来水在自身重力作用下能够流经该净化滤芯壳体1内的净化材料，不需要外界额外施加压力，且杀菌盒2的设置能够将自来水中以及净化滤芯内繁衍的微生物杀死，有效去除细菌、病毒等微生物，完成自来水的净化。
其中，限流孔11的设置除用于供净化水通过外，还可以对净化水流过的流量进行限制，当限流孔11孔径较小时，净化水流经限流 孔11的流量较小，则自来水在壳体1内存留时间较长，从而延长壳体1内各过滤材料对自来水的净化。
本实施例中，如图3所示，可以在壳体1内部设有卡扣12，卡扣12用于卡紧杀菌盒2，对杀菌盒2在壳体1内部的位置进行固定。具体的，这里的卡扣12可以为多个凸出壳体1内壁的卡接头，多个卡接头沿壳体1内壁周向均匀分布，杀菌盒2的第一盒体21可以选用聚乙烯材料制成，第一盒体21具有一定的形变能力，安装杀菌盒2时，将杀菌盒2的第一盒体21用力向下按入壳体1内，第一盒体21与卡接头相互挤压，直至第一盒体21经过卡接头的挤压后，到达卡接头的下方，多个卡接头将第一盒体21卡紧，减少杀菌盒2从壳体1内掉出情况的发生，从而确保杀菌盒2对自来水中微生物的去除。
本实施例中，可以在杀菌盒2的第一过滤网22与阴阳树脂过滤区3之间依次层叠设有PP棉层6和压板9，PP棉层6位于压板9与第一过滤网22之间，PP棉层6、压板9的形状均与壳体1的截面相匹配，卡扣12用于卡紧压板9。阴阳树脂的颗粒较小，PP棉层6位于阴阳树脂的下部，对阴阳树脂起到限位作用，减少阴阳树脂向下进入杀菌盒2内而对影响杀菌盒2内杀菌材料正常工作情况的发生；压板9在卡扣12的压紧下对PP棉层6的位置进行限定， 以减少PP棉层6在壳体1内发生偏移或褶皱情况的发生，以确保PP棉层6对阴阳树脂的隔离。
本实施例中，如图3所示，活性炭过滤区4可以包括活性炭盒5，活性炭盒5可拆卸式固设于壳体1内靠近敞口的位置，活性炭盒5包括第二盒体51和第二过滤网52，第二盒体51底部设有供水流过的第二通孔，且第二盒体51内填充有活性炭颗粒，第二过滤网52与第二盒体51可拆卸式匹配连接；阴阳树脂过滤区3由第二盒体51的底部、壳体1的侧壁以及第一过滤网22共同围设而成，阴阳树脂过滤区3内填充有阴阳树脂。净化滤芯使用时，自来水首先流经活性炭盒5的第二过滤网52，第二过滤网52一方面，对第二盒体51内的活性炭颗粒进行限制，以减少甚至避免活性炭颗粒散落；另一方面可以对自来水进行初次过滤，将自来水中体积较大的可见物质过滤掉，以减少自来水中可见物质对活性炭颗粒的污染和堵塞。自来水随后流经活性炭颗粒，经过活性炭颗粒的吸附过滤后，继续向下流入阴阳树脂中，被阴阳树脂反应净化，后续净化过程上文已经作了详细描述，这里不再赘述。
本实施例中，如图1、图3和图4所示，可以在第二过滤网52上设有排气孔521；活性炭盒5的外壁上设有排气槽511，排气槽511连通外界与阴阳树脂过滤区3。净水滤芯使用过程中，阴阳树脂 过滤区3内的阴阳树脂在水的作用下向下运动，密度变大，总体积变小，阴阳树脂过滤区3的上部与活性炭盒5的底部之间存在一定空间，不使用净化滤芯时，该空间内存满空气；当再次使用净化滤芯时，待处理水从壳体1上方流到第二过滤网52上，待处理水从网眼流入活性炭盒5及阴阳树脂过滤区3内，该空间内的气体则向上依次经过活性炭盒5和排气孔521排出壳体1，从而有效减少由于第二过滤网52上的网眼直径较小，且第二过滤网52下方存在空气层而导致待处理水在第二过滤网52上受压形成水膜，无法流入活性炭盒5内，而溢出壳体1，无法进行净化情况的发生；类似的，活性炭盒5可拆卸式固定在壳体1内，且其外壁上设有排气槽511，待处理水到达第二过滤网52时，阴阳树脂上部空间的气体受压也可以经排气槽511排出壳体1外，减少气体在壳体1内形成气压，待处理水无法进入壳体1内进行净化情况的发生。
具体的，可以在第二过滤网52上设有发射状的加强筋，加强筋均由该第二过滤网52的中心处发出，排气孔521位于该中心处，排气孔521的直径可以为2～3mm。
本实施例中，如图3所示，还可以在活性炭盒5内的活性炭与第二过滤网52之间设有海绵层7，海绵层7的形状与活性炭盒5的截面相匹配。海绵层7可以对待处理水中粒径较大的杂质进行初步 过滤，同时可以减少活性炭颗粒穿过第二过滤网52散落出壳体1情况的发生。
本实施例中，如图1和图2所示，壳体1可以为呈截头的圆锥形，阴阳树脂过滤区3由上至下依次包括A区、B区和C区，A区、B区和C区相互平行设置，且容量依次减少。阴阳树脂在一定的过水量之后就会饱和，自来水自上而下依次流过阴阳树脂过滤区3的A区、B区和C区，自来水中的盐类离子的浓度自上而下依次降低，即，A区处的阴阳树脂与自来水中的盐类离子反应最充分，当A区、B区和C区的阴阳离子容量依次减小时，虽然C区自来水中盐类离子浓度小，但是C区阴阳树脂也较少，所以A区、B区和C区达到饱和的时间较为一致，对阴阳树脂进行更换或更换滤芯时不会造成阴阳树脂的浪费。
具体的，本实施例中，如图1和图2所示，可以在壳体1外壁靠近敞口处设有外螺纹，壳体1的外壁靠近外螺纹的下端螺纹口处套设有密封圈8，密封圈8通过色熔固设于壳体1上。这里的壳体1可以通过螺纹连接别的部件连接在一起，这里的“色熔”是指将原材料(可以为具有弹性的食品级聚丙烯材料)通过高温溶解后，保持原有材料颜色的情况下进行二次注塑成形，直接成型固接在壳体1的外壁靠近外螺纹的下端螺纹口处，此时密封圈8与壳体1固接为一 个整体，不可拆卸，密封圈8与壳体1之间没有缝隙，以减少细菌的滋生，便于清洗，且能够确保密封圈8与壳体1之间的密封性，以减少使用过程中由于密封圈8密封性差而导致的漏水现象。
除上述形式外，本实施例中，还可以在壳体1外设有环状的插接凸起，插接凸起上设有环状的容纳槽，容纳槽内设有密封圈8，密封圈8通过色熔固设于壳体1上。这里的壳体1可以通过插接于别的部件连接在一起，密封圈8通过色熔设置在插接凸起的容纳槽内，当壳体1敞口处的插接凸起紧密插入别的部件中时，密封圈8与该部件的内壁紧密挤压形成密封效果，此时密封圈8与壳体1固接为一个整体，不可拆卸，密封圈8与壳体1之间没有缝隙，以减少细菌的滋生，便于清洗，且能够确保密封圈8与壳体1之间的密封性，以减少使用过程中由于密封圈8密封性差而导致的漏水现象。
具体的，本实施例中，密封圈8可以为倒“U”型密封圈81，如图5所示/或直“R”型密封圈82，如图6所示/或平垫型密封圈83，如图7所示/或“R”型密封圈84，如图8所示/或“V”型密封圈85，如图9所示。
