本申请提出一种复合滤芯组件，用于净水系统。
在本申请实施例中，参照图1至图5，该复合滤芯组件包括滤壳1和设在滤壳1内的复合滤芯，滤壳1具有原水进口（图未示）、初过滤水出口111b、加压后水进口122、纯水出口（图未示）和废水出口（图未示），复合滤芯包括前置滤芯2、膜滤芯3以及后置滤芯4，前置滤芯2和膜滤芯3由外向内依次设置且相互间隔开，后置滤芯4与膜滤芯3相连且位于膜滤芯3的下游；
初过滤水出口111b与前置滤芯2的出水端连通，加压后水进口122与膜滤芯3的进水端连通；其中，
前置滤芯2的出水端靠近膜滤芯3的进水端，初过滤水出口111b为环绕加压后水进口122设置的环形开口。
可以理解，通过将前置滤芯2、膜滤芯3以及后置滤芯4复合成一体化滤芯，有利于整机尺寸的小型化，减少接头数量及漏水风险。其中，前置滤芯2可以为PAC（PP And C，PP棉和活性炭复合滤芯）前置滤芯2，例如前置滤芯2可以包括沿径向由外至内依次分布的PP无纺布卷绕层（PP无纺布卷绕层的精度可以设置为5um）和活性炭纤维卷绕层，前置滤芯2可以有效去除铁锈、泥沙、吸附水中的异色、异味、余氯及部分有机物，确保进入膜滤芯3的水质，延长膜滤芯3的寿命。后置滤芯4可以为活性炭层，例如后置滤芯4可以为活性炭棒，后置滤芯4可以去除挥发性有机物、残余余氯，并可以保留必须的矿物质如微量钙、硅酸、碳酸根等，可以使口感甘甜、柔和。另外，本实施例中，该复合滤芯组件应用的净水系统还包括增压泵（图未示）和废水电磁阀（图未示）；将增压泵设在前置滤芯2的下游，使得进入增压泵的水经过前置滤芯2进行过滤，从而可以减少增压泵的堵塞风险，增加净水系统的寿命，提高净水系统的可靠性；将废水电磁阀与废水出口相连，废水电磁阀用于调节废水比例，以平衡净水系统的工作压力。
本申请技术方案针对大通量净水机，通过将前置滤芯2、膜滤芯3以及后置滤芯4复合成一体化滤芯，以更好地实现整机尺寸的小型化，减少接头数量以及漏水风险；同时，将用于连接增压泵的初过滤水出口111b环绕加压后水进口122设置，使增压泵通过连接件后直接套接于两接口处，避免引入连接管等结构，降低了装配的繁琐程度，提高了净水机的装配效率。
进一步地，后置滤芯4位于前置滤芯2和膜滤芯3的上侧；初过滤水出口111b和加压后水进口122位于滤壳1的下端面。本实施例中，原水进口、纯水出口以及废水出口均设于滤壳1的上部；可以理解，如此设置，使增压泵与废水电磁阀等结构分设于复合滤芯组件的上下两侧，避免增压泵与其他构件的安装发生干涉，对净水系统的各结构进行合理的排布。需要说明的是，本设计不限于此，于其他实施例中，初过滤水出口111b和加压后水进口122位于滤壳1的上端面，而原水进口、纯水出口以及废水出口均设于滤壳1的下部。
进一步地，参照图3至图5，加压后水进口122呈圆形、位于滤壳1下端面的中心处，且初过滤水出口111b和加压后水进口122同心设置。可以理解，圆形开口的工艺简单，生产方便，而将加压后水进口122和初过滤水出口111b同心设置，有利于各方向的进出水均匀，以更好地保证其与增压泵连接处的密封性。需要说明的是，本设计不限于此，于其他实施例中，加压后水进口122的圆心也可与初过滤水出口111b所在圆的圆心偏心设置，另外，加压后水进口122也可呈矩形等其他形状设置。
进一步地，加压后水进口122的半径为10mm~20mm，初过滤水出口111b的外周缘所在圆的半径为25mm~35mm。可以理解，加压后进口的半径大小对应着加压后水进口122的大小，初过滤水出口111b外周缘所在圆的半径减去加压后水进口122的半径对应着初过滤水出口111b的大小；初过滤水出口111b的尺寸以及加压后水进口122的尺寸过大或过小，都不利于保证复合滤芯组件内部水流循环的压力以及两开口与增压泵连接处的密封性。
进一步地，滤壳1包括外桶体11和设于外桶体11内的内桶体12，外桶体11的内壁面和内桶体12的外壁面之间设有前置滤芯2，内桶体12内设有膜滤芯3、上侧设有后置滤芯4；外桶体11的下端面设有第一开口，第一开口周缘朝下延伸形成第一环筋111a；内桶体12的下端面设有第二开口，第二开口沿上下向的投影位于第一开口内，第二开口周缘朝下延伸形成第二环筋121，第二环筋121伸入第一环筋111a之间；第一环筋111a的内周面与第二环筋121的外周面围合形成初过滤水出口111b，第二环筋121的内周面围合形成加压后水进口122。
可以理解，如此设置，简单、快捷地实现加压后水进口122以及初过滤水出口111b的结构组成，简化了复合滤芯组件的装配。本实施例中，外桶体11包括桶本体111和盖合桶本体111设置的上盖112，上盖112上设有原水进口、废水出口以及纯水出口，具体地，原水进口连通于外桶体11和内桶体12之间的上部，原水从上部流入，经过前置滤芯2过滤后，从外桶体11和内桶体12之间下部的初过滤水出口111b流出，进入增压泵，经过增压泵增压后，从加压后水进口122流入内桶体12，以进行后续过滤过程。另外，本实施例中，复合滤芯组件还包括呈环形的端盖13，该端盖13环设于内桶体12与外桶体11之间的下部，端盖13的上端面用以支撑前置滤芯2，当然，于其他实施例中，前置滤芯2也可通过其他方式固定于外桶体11和内桶体12之间，本设计对此不作限制。需要说明的是，本设计不限于此，于其他实施例中，初过滤水出口111b和加压后水进口122均设于外桶体11的下端面上，而初过滤水出口111b为环绕加压后水进口122的环形开口。
进一步地，第一环筋111a的外周面以及第二环筋121的外周面上均设有密封结构，密封结构用以密封连接净水系统的增压泵的转接件（图未示）。本实施例中，增压泵通过一转接件连接初过滤水出口111b和加压后水进口122，该转接件具有同心设置的外环部和内环部，内环部的内周面与第二环筋121的外周面密封连接，外环部的内周面与第一环筋111a的内周面密封连接，当然，于其他实施例中，增压泵与第一环筋111a和第二环筋121也可具体通过其他方式连接，本设计不限于此。
进一步地，密封结构为环设于第一环筋111a和第二环筋121外周面的密封环槽111c，以及设于密封环槽111c内的密封件111d。可以理解，密封环槽111c和密封件111d的配合使用是现有技术中净水机领域广泛使用的技术手段，具有密封性强、工艺简单等优点，当然，于其他实施例中，密封结构还可为具体为凸设于第一环筋111a和第二环筋121周面的弹性密封凸筋，本设计对此不作限制。另外，本实施例中，密封件111d为层叠设置的至少两个O型圈，可以理解，O型圈容易获得且价格便宜，有利于降低净水系统的成本；当然，于其他实施例中，密封件111d也可为涂覆于密封环槽111c内的密封胶，本设计对此不作限制。
进一步地，外桶体11的上部设有用以连接外部结构的接头部14，接头部14上并行设有原水接头141、纯水接头142以及废水接头143，原水接头141连通原水进口，纯水接头142连通纯水口，废水接头143连通废水口。可以理解，如此设置，将多个接头紧凑排布于一起，有利于如废水电磁阀等外接结构的连接，简化装配过程。本实施例中，接头部14设于上盖112的上端面，且该接头部14具有凸出于上盖112的安装部，安装部的下端面自左至右朝下依次凸设有原水接头141、纯水接头142以及废水接头143；当然，于其他实施例中，接头部14也可设于外桶体11上部的外周面上，本设计对此不作限制。
进一步地，膜滤芯3包括中心集水管32和卷绕在中心集水管32上的膜滤芯本体31，加压后水进口122连通膜滤芯3本体的进水端，中心集水管32的管壁设有多个连通口321，多个连通口321连通膜滤芯本体31的出水端，中心集水管32的顶端连通后置滤芯4的进水端。可以理解，如此设置，合理利用膜滤芯本体31的内腔，进行加压后水的引入以及二次过滤水的导出。具体地，从加压后水进口122流出的水被引流到内桶体12的内周面附近，进入膜滤芯3本体进行第二次过滤，废水从膜滤芯本体31上侧被导流至废水口排出，二次过滤水通过连通口321进入中心集水管32，继而被导流至后置滤芯4的进水端。
进一步地，参照图4和图6，复合滤芯组件还包括呈中空设置的连接壳15，连接壳15至少部分设于内桶体12内的上部，且中心集水管32的上端连通连接壳15的内腔；连接壳15的外壳壁与内桶体12的内壁之间，限制出自膜滤芯本体31导向废水出口的废水流道16；后置滤芯4设于连接壳15内，后置滤芯4和连接壳15的内壁之间，限定出流通流道，后置滤芯4的内腔限定出导向纯水出口的纯水流道17。
本实施例中，连接壳15包括桶形壳壁，以及设于桶形壳壁上端面的环形接头，上盖112包括盖合桶本体111设置的上盖本体112a，以及自上盖112本体112a的下端面由外至内依次朝下延伸的第一环形部112b、第二环形部112c以及第三环形部112d，第一环形部112b的内周面与内桶体12的外周面密封连接，第二环形部112c的内周面与桶形壳壁的外周面密封连接，第三环形部112d的内周面与环形接头的外周面密封连接；如此，经过膜滤芯本体31过滤后的废水，从内桶体12的内周面与第二环形部112c的外周面之间的废水流道16流至废水出口；经过膜滤芯本体31过滤后的二次过滤水，通过中心集水管32，进入桶形壳壁内，进入后置滤芯4，经过后置滤芯4过滤后，从后置滤芯4内腔形成纯水流道17流出，进入纯水出口，完成整个净水过程。需要说明的是，本设计不限于此，于其他实施例中，连接壳15也可具体为其他形状或设计，以实现废水流道16以及纯水流道17。
本申请还提出一种净水系统，该净水系统包括增压泵和复合滤芯组件，该复合滤芯组件的具体结构参照上述实施例，增压泵一端连接初过滤水出口、另一端连接加压后水进口，由于本净水系统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。
本申请还提出一种复合滤芯组件，用于净水系统。
在本申请实施例中，参照图7至图11，该复合滤芯组件包括滤壳1’和设在滤壳1’内的复合滤芯，滤壳1’具有原水进口（图未示）、初过滤水出口111b’、加压后水进口122’、蓄水口（图未示）、纯水出口（图未示）和废水出口（图未示），复合滤芯包括前置滤芯2’、膜滤芯3’以及后置滤芯4’，前置滤芯2’和膜滤芯3’由外向内依次设置且相互间隔开，后置滤芯4’与膜滤芯3’相连且位于膜滤芯3’的下游；
初过滤水出口111b’与前置滤芯2’的出水端连通，加压后水进口122’与膜滤芯3’的进水端连通，蓄水口与膜滤芯3’的出水端连通且与后置滤芯4’的进水端连通；其中，
前置滤芯2’的出水端靠近膜滤芯3’的进水端，初过滤水出口111b’为环绕加压后水进口122’设置的环形开口。
可以理解，通过将前置滤芯2’、膜滤芯3’以及后置滤芯4’复合成一体化滤芯，有利于整机尺寸的小型化，减少接头数量及漏水风险。其中，前置滤芯2’可以为PAC（PP And C，PP棉和活性炭复合滤芯）前置滤芯2’，例如前置滤芯2’可以包括沿径向由外至内依次分布的PP无纺布卷绕层（PP无纺布卷绕层的精度可以设置为5um）和活性炭纤维卷绕层，前置滤芯2’可以有效去除铁锈、泥沙、吸附水中的异色、异味、余氯及部分有机物，确保进入膜滤芯3’的水质，延长膜滤芯3’的寿命。后置滤芯4’可以为活性炭层，例如后置滤芯4’可以为活性炭棒，后置滤芯4’可以去除挥发性有机物、残余余氯，并可以保留必须的矿物质如微量钙、硅酸、碳酸根等，可以使口感甘甜、柔和。另外，本实施例中，该复合滤芯组件应用的净水系统还包括增压泵（图未示）、废水电磁阀（图未示）以及蓄水装置（图未示）；将增压泵设在前置滤芯2’的下游，使得进入增压泵的水经过前置滤芯2’进行过滤，从而可以减少增压泵的堵塞风险，增加净水系统的寿命，提高净水系统的可靠性；将废水电磁阀与废水出口相连，废水电磁阀用于调节废水比例，以平衡净水系统的工作压力；将蓄水装置与蓄水口相连，蓄水装置用于储存从蓄水口流出的纯水。废水电磁阀与废水出口相连。由此，通过设置的蓄水装置，可以将纯水储存在蓄水装置中，由此在水压不足时依然可以满足用户的大通量需求。
本申请技术方案针对小通量净水机，通过将前置滤芯2’、膜滤芯3’以及后置滤芯4’复合成一体化滤芯，以更好地实现整机尺寸的小型化，减少接头数量以及漏水风险；同时，将用于连接增压泵的初过滤水出口111b’环绕加压后水进口122’设置，使增压泵通过连接件后直接套接于两接口处，避免引入连接管等结构，降低了装配的繁琐程度，提高了净水机的装配效率。
进一步地，后置滤芯4’位于前置滤芯2’和膜滤芯3’的上侧；初过滤水出口111b’和加压后水进口122’位于滤壳1的下端面。本实施例中，原水进口、蓄水口、纯水出口以及废水出口均设于滤壳1’的上部；可以理解，如此设置，使增压泵与蓄水装置等结构分设于复合滤芯组件的上下两侧，避免增压泵与其他构件的安装发生干涉，对净水系统的各结构进行合理的排布。需要说明的是，本设计不限于此，于其他实施例中，初过滤水出口111b’和加压后水进口122’位于滤壳1’的上端面，而原水进口、蓄水口、纯水出口以及废水出口均设于滤壳1’的下部。
进一步地，参照图9至图11，加压后水进口122’呈圆形、位于滤壳1’下端面的中心处，且初过滤水出口111b’和加压后水进口122’同心设置。可以理解，圆形开口的工艺简单，生产方便，而将加压后水进口122’和初过滤水出口111b’同心设置，有利于各方向的进出水均匀，以更好地保证其与增压泵连接处的密封性。需要说明的是，本设计不限于此，于其他实施例中，加压后水进口122’的圆心也可与初过滤水出口111b’所在圆的圆心偏心设置，另外，加压后水进口122’也可呈矩形等其他形状设置。
进一步地，加压后水进口122’的半径为10mm~20mm，初过滤水出口111b的外周缘所在圆的半径为25mm~35mm。可以理解，加压后进口的半径大小对应着加压后水进口122’的大小，初过滤水出口111b’外周缘所在圆的半径减去加压后水进口122’的半径对应着初过滤水出口111b’的大小；初过滤水出口111b’的尺寸以及加压后水进口122’的尺寸过大或过小，都不利于保证复合滤芯组件内部水流循环的压力以及两开口与增压泵连接处的密封性。
进一步地，滤壳1’包括外桶体11’和设于外桶体11’内的内桶体12’，外桶体11’的内壁面和内桶体12’的外壁面之间设有前置滤芯2’，内桶体12’内设有膜滤芯3’、上侧设有后置滤芯4’；外桶体11’的下端面设有第一开口，第一开口周缘朝下延伸形成第一环筋111a’；内桶体12’的下端面设有第二开口，第二开口沿上下向的投影位于第一开口内，第二开口周缘朝下延伸形成第二环筋121’，第二环筋121’伸入第一环筋111a’之间；第一环筋111a’的内周面与第二环筋121’的外周面围合形成初过滤水出口111b’，第二环筋121’的内周面围合形成加压后水进口122’。
可以理解，如此设置，简单、快捷地实现加压后水进口122’以及初过滤水出口111b’的结构组成，简化了复合滤芯组件的装配。本实施例中，外桶体11’包括桶本体111’和盖合桶本体111’设置的上盖112’，上盖112’上设有原水进口、蓄水口、废水口以及纯水出口，具体地，原水进口连通于外桶体11’和内桶体12’之间的上部，原水从上部流入，经过前置滤芯2’过滤后，从外桶体11’和内桶体12’之间下部的初过滤水出口111b’流出，进入增压泵，经过增压泵增压后，从加压后水进口122’流入内桶体12’，以进行后续过滤过程。另外，本实施例中，复合滤芯组件还包括呈环形的端盖13’，该端盖13’环设于内桶体12’与外桶体11’之间的下部，端盖13’的上端面用以支撑前置滤芯2’，当然，于其他实施例中，前置滤芯2’也可通过其他方式固定于外桶体11’和内桶体12’之间，本设计对此不作限制。需要说明的是，本设计不限于此，于其他实施例中，初过滤水出口111b’和加压后水进口122’均设于外桶体11’的下端面上，而初过滤水出口111b’为环绕加压后水进口122’的环形开口。
进一步地，第一环筋111a’的外周面以及第二环筋121’的外周面上均设有密封结构，密封结构用以密封连接净水系统的增压泵的转接件（图未示）。本实施例中，增压泵通过一转接件连接初过滤水出口111b’和加压后水进口122’，该转接件具有同心设置的外环部和内环部，内环部的内周面与第二环筋121’的外周面密封连接，外环部的内周面与第一环筋111a’的内周面密封连接，当然，于其他实施例中，增压泵与第一环筋111a’和第二环筋121’也可具体通过其他方式连接，本设计不限于此。
进一步地，密封结构为环设于第一环筋111a’和第二环筋121’外周面的密封环槽111c’，以及设于密封环槽111c’内的密封件111d’。可以理解，密封环槽111c’和密封件111d’的配合使用是现有技术中净水机领域广泛使用的技术手段，具有密封性强、工艺简单等优点，当然，于其他实施例中，密封结构还可为具体为凸设于第一环筋111a’和第二环筋121’周面的弹性密封凸筋，本设计对此不作限制。另外，本实施例中，密封件111d’为层叠设置的至少两个O型圈，可以理解，O型圈容易获得且价格便宜，有利于降低净水系统的成本；当然，于其他实施例中，密封件111d’也可为涂覆于密封环槽111c’内的密封胶，本设计对此不作限制。
进一步地，外桶体11’的上部设有用以连接外部结构的接头部14’，接头部14’上并行设有原水接头141’、蓄水接头142’、纯水接头143’以及废水接头144’，原水接头141’连通原水进口，蓄水接头142’连通蓄水口，纯水接头143’连通纯水口，废水接头144’连通废水口。可以理解，如此设置，将多个接头紧凑排布于一起，有利于如蓄水装置等外接结构的连接，简化装配过程。本实施例中，接头部14’设于上盖112’的上端面，且该接头部14’具有凸出于上盖112’的安装部，安装部的下端面自左至右朝下依次凸设有原水接头141’、蓄水接头142’、纯水接头143’以及废水接头144’；当然，于其他实施例中，接头部14’也可设于外桶体11’上部的外周面上，本设计对此不作限制。
进一步地，膜滤芯3’包括中心集水管32’和卷绕在中心集水管32’上的膜滤芯本体31’，加压后水进口122’连通膜滤芯本体31’的进水端，中心集水管32’的管壁设有多个连通口321’，多个连通口321’连通膜滤芯本体31’的出水端，中心集水管32’的顶端连通蓄水口和后置滤芯4’的进水端。可以理解，如此设置，合理利用膜滤芯本体31’的内腔，进行加压后水的引入以及二次过滤水的导出。具体地，从加压后水进口122’流出的水被引流到内桶体12’的内周面附近，进入膜滤芯本体31’进行第二次过滤，废水从膜滤芯本体31’上侧被导流至废水口排出，二次过滤水通过连通口321’进入中心集水管32’，继而被导流至后置滤芯4’的进水端。
进一步地，参照图10和图12，复合滤芯组件还包括呈中空设置的连接壳15’，连接壳15’至少部分设于内桶体12’内的上部，且中心集水管32’的上端连通连接壳15’的内腔；连接壳15’的外壳壁与内桶体12’的内壁之间，限制出自膜滤芯本体31’导向废水出口的废水流道16’；后置滤芯4’设于连接壳15’内，后置滤芯4’和连接壳15’的内壁之间，限定出自中心集水管32’的上端导向蓄水口的蓄水流道17’，后置滤芯4’的内腔限定出导向纯水出口的纯水流道18。
本实施例中，连接壳15’包括桶形壳壁，以及设于桶形壳壁上端面的环形接头，上盖112’包括盖合桶本体111’设置的上盖本体112a’，以及自上盖本体112a’的下端面由外至内依次朝下延伸的第一环形部112b’、第二环形部112c’以及第三环形部112d’，第一环形部112b’的内周面与内桶体12’的外周面密封连接，第二环形部112c’的内周面与桶形壳壁的外周面密封连接，第三环形部112d’的内周面与环形接头的外周面密封连接；如此，经过膜滤芯本体31’过滤后的废水，从内桶体12’的内周面与第二环形部112c’的外周面之间的废水流道16’流至废水出口；经过膜滤芯本体31’过滤后的二次过滤水，通过中心集水管32’，进入桶形壳壁内，一部分从第二环形部112c’的内周面以及桶形壳壁的内周面之间的蓄水流道17’流至蓄水口，另一部分进入后置滤芯4’，经过后置滤芯4’过滤后，从后置滤芯4’内腔形成纯水流道18’流出，进入纯水出口，完成整个净水过程。需要说明的是，本设计不限于此，于其他实施例中，连接壳15’也可具体为其他形状或设计，以实现废水流道16’、蓄水流道17’以及纯水流道18’。
本实用新型还提出一种净水系统，该净水系统包括增压泵、蓄水装置以及复合滤芯组件，该复合滤芯组件的具体结构参照上述实施例，增压泵一端连接初过滤水出口、另一端连接加压后水进口，蓄水装置与蓄水口相连，由于本净水系统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。
