具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面结合附图1和图2具体描述根据本发明第一方面实施例的滤芯组件100。
根据本发明实施例的滤芯组件100包括滤壳10、接头20、封盖30、滤芯40、中心管50和止水胶垫60。具体而言，滤壳10内限定有过滤腔10a，接头20设在滤壳10上，接头20上设有与过滤腔10a连通的进水口和出水口，封盖30设在接头20上且位于过滤腔10a内。
其中，封盖30包括：接头管31、支撑板32、第一隔板33、第二隔板34，接头管31形成为沿滤壳10的轴向延伸的管状，接头管31的外端与接头20相连，支撑板32设在接头管31的内端的外侧且沿滤壳10的径向向外延伸，第一隔板33和第二隔板34分别设在支撑板32上且朝向滤壳10内延伸，第一隔板33和第二隔板34分别形成为沿滤壳10的周向延伸的环形，滤芯40设在过滤腔10a内且卡接在第一隔板33和第二隔板34之间，中心管50插接在接头管31内且与出水口连通，止水胶垫60可活动地设在接头管31以打开和关闭进水口，止水胶垫60被构造成当进水口进水时打开进水口且在进水口不进水时关闭进水口。
换言之，该滤芯组件100主要由滤壳10、接头20、封盖30、滤芯40、中心管50和止水胶垫60组成，滤壳10的内部限定出一端敞开的过滤腔10a，接头20设在滤壳10上且与滤壳10的敞开端相连以封闭过滤腔10a的开口，接头20沿竖直方向(如图1中所示的上下方向)延伸，接头20的一端(如图1所示的下端)具有与过滤腔10a相连通的进水口和出水口，接头20的上端与滤壳10相连接，封盖30、滤芯40和中心管50位于过滤腔10a内，中心管50设在过滤腔10a的中央位置，中心管50沿着滤壳10的中心轴线延伸，且中心管50的下端插接在接头20内且与接头20上的出水口相连通,中心管50的上端可以通过滤芯支撑筋11支撑(如图5所示)，从而便于净水通过中心管50流出。
封盖30主要由接头管31、支撑板32、第一隔板33、第二隔板34组成，接头管31沿着滤壳10的轴向延伸呈管状布置，接头管31穿设在接头20内侧且与接头20相连接，支撑板32布置在过滤腔10a内且邻近接头20的内端，支撑板32在滤壳10的径向方向上向外延伸，沿着支撑板32的径向间隔地布置有第一隔板33和第二隔板34，即第一隔板33和第二 隔板34在支撑板32的径向上间隔开设置，具体地，第一隔板33位于支撑板32的外周，第二隔板34位于支撑板32的内侧，第一隔板33和第二隔板34分别沿着滤壳10的周向延伸呈环形布置。
进一步地，滤芯40大致形成为环柱体且设在过滤腔10a内，环柱状滤芯40的内径与第二隔板34的径向尺寸大致相等、环柱状滤芯40的外径与第一隔板33的径向尺寸大致相等，从而将滤芯40卡接在第一隔板33和第二隔板34将滤芯40之间，实现滤芯40的固定连接，避免发生串水现象。
再者，止水胶垫60沿轴向方向(如图1所示上下方向)延伸，止水胶垫60同轴套设在接头管31的外侧，并且通过止水胶垫60与接头20的配合，实现打开或者自动关闭进水口，进而既可以保证滤芯组件100的进水，又可以避免进水停止时，水流通过进水口回流出来，带来安全隐患。
滤芯组件100在工作时，水流由接头20上的进水口流入过滤腔10a内时，止水胶垫60在水流压力作用下打开，从而连通过滤腔10a与进水口，使得水流可以流入过滤腔10a内部，然后经过封盖30的外侧到达滤芯40，通过滤芯40的过滤作用继续向上流动，最后，过滤后的水经过中心管50的上端进入中心管50内，沿着中心管50流动到达出水口，经过过滤后的净水最后流出滤芯组件100之外，以供用户使用。
而当水流停止流入时，止水胶垫60关闭，从而封闭进水口，进而使得水流通过进水口与外界导通的通路被阻断，有效地避免水流通过进水口回流出滤芯组件100，带来安全隐患，降低用户体验。
由此，根据本发明的滤芯组件100，通过在接头管31上设置止水胶垫60，并且将止水胶垫60构造成在进水口进水时可以打开进水口，而在进水口不进水时可以自动关闭进水口，从而既可以保证水路正常流通，又可以有效地避免在进水口停止进水时，滤芯组件100内的水通过进水口回流出来，并且可以避免造成使用该滤芯组件100的净水器的电路短路的风险，进而提高滤芯组件100的安全性能以及用户体验，另外，采用止水胶垫60与接头管31之间可活动地相连，不仅使得滤芯组件100的结构更加简单、便于用户装拆，而且，也可以有效地提高生产效率。
其中，支撑板32的上端面还布置有支撑筋35，可选地，支撑筋35的截面形状可以形成为三角形，支撑筋35位于第一隔板33和第二隔板34之间，在滤芯40卡接在第一隔板33与第二隔板34之间时，滤芯40的下端面与支撑板32的上端面接触，滤芯40的下端面止抵在支撑筋35上，支撑筋35的顶部嵌入滤芯40端面内，可以保证支撑板32与滤芯40之间的密封性和连接可靠性，防止滤芯组件100内发生串水现象。
可选地，进水口设在接头管31的外周，从而既可以避免与接头管31产生干涉，简化滤 芯组件100的结构，当然，进水口的设置数量可以根据实际的设计需求进行调整，以保证滤芯组件100的过滤效率以及过滤均匀性。
其中，止水胶垫60包括连接部61和活动部62，连接部61套设在接头管31上，活动部62与连接部61可活动地相连，活动部62在进水口进水时被挤压以打开进水口，且在进水口不进水时回复并关闭进水口。
参照图2，止水胶垫60主要由连接部61和活动部62组成，连接部61套设在接头管31上，也就是说，连接部61与接头管31同轴布置，且连接部61设在接头管31的外周侧，活动部62大致形成为沿径向延伸的环状体，环状体活动部62内壁面(即邻近接头管31的一侧)与连接部61可活动地相连，活动部62的外壁面(即远离接头管31的一侧)与接头20的内壁止抵。
当水流由接头20上的进水口流入过滤腔10a内时，止水胶垫60在水流压力作用下产生变形，从而连通过滤腔10a与进水口，使得水流可以流入过滤腔10a内部，然后经过封盖30的外侧到达滤芯40，通过滤芯40的过滤作用继续向上流动，最后，过滤后的水经过中心管50的上端进入中心管50内，沿着中心管50流动到达出水口，经过过滤后的净水最后流出滤芯组件100之外，以供用户使用。
而当水流停止流入时，止水胶垫60恢复形变，从而封闭进水口，进而使得水流通过进水口与外界导通的通路被阻断，有效地避免水流通过进水口回流出滤芯组件100，带来安全隐患，降低用户体验。
可选地，连接部61形成为管状，连接部61的外端止抵接头，连接部61的内端止抵支撑板32，活动部62设在连接部的外端的外壁面上且形成为沿其周向延伸的环形。
具体地，如图2所示，连接部61大致形成为沿轴向方向(如图2所示上下方向)延伸的管状，连接部61套设在接头管31上，且连接部61的内端(即图2中所示邻近支撑板32的一端)止抵支撑板32，连接部61的外端(即图2中所示远离支撑板32的一端)止抵接头20，从而利用接头20和支撑板32限制连接部61在轴向的自由度，避免连接部61在轴向上产生窜动，活动部62大致形成为沿径向延伸的环状体，环状体活动部62的内壁面(即邻近接头管31的一侧)与连接部61的外端的外壁面止抵相连，活动部62的外壁面(即远离接头管31的一侧)与接头20的内壁止抵。
当水流由接头20上的进水口流入过滤腔10a内时，止水胶垫60在水流压力作用下产生变形，从而连通过滤腔10a与进水口，使得水流可以流入过滤腔10a内部，然后经过封盖30的外侧到达滤芯40，通过滤芯40的过滤作用继续向上流动，最后，过滤后的水经过中心管50的上端进入中心管50内，沿着中心管50流动到达出水口，经过过滤后的净水最后流出滤芯组件100之外，以供用户使用。
当水流停止流入时，止水胶垫60恢复形变，从而封闭进水口，进而使得水流通过进水口与外界导通的通路被阻断，有效地避免水流通过进水口回流出滤芯组件100，带来安全隐患，降低用户体验。
其中，活动部62垂直于连接部61的轴向延伸。
参照图2，活动部62沿接头管31的径向延伸，连接部61沿接头管31的轴向(如图2所示上下方向)延伸，活动部62与连接部61垂直相连，从而既可以保证止水胶垫60与连接部61以及接头20的配合，进而保证在进水口不进水时，过滤腔10a的密闭性。
优选地，连接部61与活动部62一体成型。也就是说，连接部61与活动部62一体加工成一个整体结构，从而保证二者件连接的可靠性，保证二者连接处的密闭效果，而且成型方便简化加工工艺，提供生产效率，当然，连接部61与活动部62之间也可以是固定连接的组合件，对此，本发明并不做出限定。
如图1所示，第一隔板33与第二隔板34同轴设置且第一隔板33位于第二隔板34外周，滤芯40的截面形成为环形，也就是说，第一隔板33与第二隔板34的中心轴线相重合，在滤壳10的径向方向上第一隔板33位于第二隔板34的外侧，滤芯40的截面呈环形布置，即滤芯40沿着滤壳10的周向形成为在竖直方向延伸的环形柱体，进入过滤腔10a内的水沿着滤壳10的径向由外侧向内侧穿过滤芯40，进而对水进行过滤，将水中的杂质过滤干净。
有利地，滤芯40的内壁面与第二隔板34的外壁面过盈配合，滤芯40的外壁面与第一隔板33的内壁面过盈配合。即滤芯40的内壁的径向尺寸小于第二隔板34的外壁的径向尺寸，滤芯40的外壁的径向尺寸大于第一隔板33的内壁的径向尺寸，通过滤芯40的内壁面与第二隔板34的外壁面过盈配合，滤芯40的外壁面与第一隔板33的内壁面过盈配合，不仅滤芯40与第二隔板34相配合的结构简单，加工过程方便，且有效地保证滤芯40的内壁面与第二隔板34的外壁面，外壁面与第一隔板33的内壁面之间的密封性，避免滤芯40与第二隔板34、第一隔板33之间存在间隙，防止发生串水。
其中，第一隔板33的轴向高度小于第二隔板34的轴向高度。具体地，如图1所示，第二隔板34在滤芯40的轴向上的高度大于第一隔板33在滤芯40的轴向上的高度，这样不仅可以增大第二隔板34与滤芯40的内壁面的过盈配合面积，保证第二隔板34的外壁与滤芯40的内壁之间的有效密封性，还有利于将滤芯40牢牢地卡接在封盖30内，保证结构的稳定性，连接十分可靠。
优选地，封盖30为一体成型件，由此，一体形成的结构不仅可以保证滤芯组件100的结构、性能稳定性，并且方便成型、制造简单，而且省去了多余的装配件以及连接工序，大大提高了滤芯组件100的装配效率，保证滤芯组件100的连接可靠性，再者，一体形成的结构的整体强度和稳定性较高，组装更方便，寿命更长。
根据本发明第二方面的净水器(未示出)，包括上述实施例中的滤芯组件100，由于根据本发明上述实施例的滤芯组件100具有上述技术效果，故根据本发明实施例的净水器也具有相应的技术效果，即该净水器的结构简单、密封性能好、生产效率高、安全性好、用户体验佳。
具体地，通过在净水器的滤芯组件100的接头管31上设置止水胶垫60，并且将止水胶垫60构造成在进水口进水时可以打开进水口，而在进水口不进水时可以自动关闭进水口，从而既可以保证水路正常流通，又可以有效地避免在进水口停止进水时，滤芯组件100内的水通过进水口回流出来，并且可以避免造成使用该滤芯组件100的净水器的电路短路的风险，从而提高滤芯组件100的安全性能，进而提升净水器的品质，提升用户体验。另外，采用止水胶垫60与接头管31之间可活动地相连，不仅使得净水器的滤芯组件100的结构更加简单、便于用户装拆，而且，也可以有效地提高生产效率，进而提升净水器的生产效率。
