随着净水机产品越来越受广大消费者的欢迎，消费者对产品体验的要求也越来越高，其中，拆卸时自动封水的滤芯装置最受消费者的关注。
现有技术中出现了各种自动封水的滤芯装置，主要包括以下几种技术：
一，滤芯装置上设置止水阀实现通水和断水；
二，滤芯装置的端部设置旋转结构，通过错位进行通水和断水；
三，滤座上设置旋转结构，通过错位进行通水和断水。
针对上述第一种技术，止水阀的数量会随着滤芯装置上进出水口的增加而增加，进而导致滤芯装置的组装会越来越繁琐，具有生产效率低，成本高昂的缺点。
针对上述第二种技术，由于滤芯装置端部设置的旋转结构是由螺丝固定的，而螺丝的扭力难以控制，从而导致旋转结构上设置的密封圈的压缩量与旋转手感之间难平衡，存在漏水的隐患。
针对上述第三种技术，滤座上设置旋转结构会使滤座的结构复杂化，组装难度增加。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
如图1至图2所示，本发明实施例提供一种滤芯装置，主要包括滤芯本体1和底座2，底座2设有凹腔21，滤芯本体1的第一端旋接于凹腔21内；滤芯本体1设有本体流道，底座2设有与本体流道相对应的底座流道，除此之外，本体流道与底座流道之间还设有自动锁水组件22，滤芯本体1与底座2通过相对旋转控制自动锁水组件22的打开和关闭，以实现本体流道与底座流道的连通和断开。
进一步地，如图2至图4所示，滤芯本体1包括壳体11、滤材12以及端盖19，壳体11为空心圆柱体，其内部为从其一端贯穿至另一端的过滤腔体111，其两端分别设有与过滤腔体111相连通的第一开口112和第二开口113，端盖19盖于第二开口113上。滤材12为与壳体11形状相似的圆柱体，滤材12的内部设有从其一端贯穿至另一端的中心管121，且中心管121的管壁上设有过流孔1211，滤材12设于过滤腔体111内并在过滤腔体111内形成过滤流道。具体而言，过滤流道包括第四进水流道14a、第四出水流道14b以及第四排污流道14c，其中，壳体11的内侧壁与滤材12的外侧壁之间形成第四进水流道14a，中心管121的管道即为第四出水流道14b，滤材12本身即为第四排污流道14c。
进一步地，如图2至图5所示，滤芯本体1还包括止水组件13，其包括可相对转动的分水件131和挡水件132；壳体11的内侧壁在靠近第一开口112的位置设有隔板114，隔板114和壳体11的内侧壁围成安装位115，第一开口112为安装位115的安装口，挡水件132安装于安装位115内并可相对于壳体11转动，而且，当壳体11的第一端旋接于底座2的凹腔21内时，底座2将限制挡水件转动；分水件131设于隔板114背离挡水件132一侧的过滤腔体111内，并且，分水件131可随着壳体11一起转动，滤材12与分水件131远离挡水件132的一端相连接。
进一步地，如图3至图5所示，分水件131通过转轴结构与挡水件132相连接，转轴结构包括转轴1311和转孔1321，其中，转轴1311通过连接柱1312连接于分水件131的一端，转孔1321设于挡水件132的一端，隔板114的中央设有通孔，转轴1311穿过通孔插接于转孔1321内实现挡水件132与分水件131的转动连接。当然，分水件131的转轴1311和挡水件132的转孔1321可以互换位置，即转孔1321设于分水件131的一端，转轴1311设于挡水件132的一端，此种位置互换所带来的技术效果一样。
进一步地，如图6至图7所示，分水件131设有分水流道，转轴1311的侧壁设有与分水流道相连通的分水件对接口，具体而言，分水流道包括第三进水流道15a、第三出水流道15b以及第三排污流道15c；分水件对接口包括与第三进水流道15a相连通的第三进水口151、与第三出水流道15b相连通的第三出水口152以及与第三排污流道15c相连通的第三排污口153，并且，上述三个分水件对接口沿转轴1311的周向均匀分布于转轴1311的侧壁上。对应的，挡水件132设有挡水流道，转孔1321的侧壁设有与挡水流道相连通的挡水件对接口，具体而言，挡水流道包括第二进水流道16a、第二出水流道16b以及与第二排污流道16c；挡水件对接口包括与第二进水流道16a相连通的第二进水口161、与第 二出水流道16b相连通的第二出水口162以及与第二排污流道16c相连通的第二排污口163，并且，上述三个挡水件对接口沿转孔1321的周向均匀分布于转孔1321的侧壁上。基于此，转轴1311与转孔1321的相对旋转侧面即为分水件对接口与挡水件对接口的对接面，分水件131与挡水件132可通过相对旋转控制第三进水口151与第二进水口161的对接和错开、第三出水口152与第二出水口的对接和错开以及第三排污口153与第二排污口163的对接和错开，以实现第三进水流道15a与第二进水流道16a的连通和断开、第三出水流道15b与第二出水流道16b的连通和断开以及第三排污流道15c与第二排污流道16c的连通和断开。显然，上述过滤流道、分水流道以及挡水流道组成滤芯本体的本体流道。
基于上述结构，一方面，通过分水件131与挡水件132的相对旋转，止水组件13能够实现通水和断水，从而能够在滤芯装置的拆下过程中防止过滤腔体111内的残留水流出；另一方面，通过壳体11与底座2的相对旋转，自动锁水组件22能够控制滤芯装置与外接管道之间的通水和断水，从而能够在滤芯装置的拆下过程中防止外接管道中的水流溢出，由此，止水组件13和自动锁水组件22组成的双向封水结构彻底杜绝了漏水的隐患，保证滤芯装置在拆下时始终保持干燥整洁。另外，由于分水件对接口与挡水件对接口的对接面为转轴1311与转孔1321的相对旋转侧面，从而简化了组装结构，提升了生产制造的效率，降低了成品的不良率，并且在保证密封性的前提下提高了分水件131与挡水件132相对旋转时的顺滑度，降低了旋转时的顿挫感，具有较好的操控手感。
进一步地，在图4的基础上参见图6和图12，为了使分水件131能够随着壳体11一起转动，分水件131的边缘设有卡凸181，壳体11的内侧壁设有与卡凸181相对应的限位槽182，卡凸181与限位槽182构成的固定限位结构可防止分水件131相对于壳体11转动。优选地，卡凸181设为两个或两个以上，两个或两个以上的卡凸181沿分水件131的周向均匀分布，限位槽182与卡凸181数量相等且一一对应，也即，两个或两个以上的限位槽182沿壳体11的周向均匀分布。在此基础上，为了防止分水件131安装错误，保证各分水件对接口与各挡水件对接口准确地对接，全部卡凸181中至少有两个卡凸181的尺寸不相同，并且，各限位槽182与各卡凸181一一对应。由此，该固定限位结构具有了防呆功能，尺寸对应的卡凸181和限位槽182确定了分水件131在过滤腔体111内的唯一安装位置，保证了各分水件对接口与各挡水件对接口的准确对应。当然，卡凸181和限位槽182可互换位置，即卡凸181设于壳体11的内侧壁上，限位槽182设于分水件131的外侧壁上，此种位置互换所带来的技术效果一样。
进一步地，如图3、图4和图8所示，为了限制挡水件与分水件之间的相对旋转角度，防止出现窜水，隔板114朝向挡水件132的一侧表面设有第一凸块171，挡水件132朝向隔板114的一端设有与第一凸块171相对应的第一滑槽172，第一凸块171与第一滑槽172构成滑动限位结构，并且，该滑动限位结构与止水组件13之间存在如下关联：当第一凸块171随着壳体11的转动滑至第一滑槽172的第一端时，分水件对接口与挡水件对接口完全对接；当第一凸块171随着壳体11的转动滑至第一滑槽172的第二端时，分水件对接口与挡水件对接口完全错开。基于此，使用者无需刻意控制分水件131与挡水件132的相对旋转角度，即可快速准确地将分水件对接口与挡水件对接口准确地对接或错开，因而具有较好的操控性。当然，第一凸块171和第一滑槽172可以互换位置，即第一凸块171设于挡水件132上，第一滑槽172设于壳体的隔板114上，此种位置互换所带来的技术效果一样。
进一步地，如图4至图7所示，分水件131远离挡水件132的一端设有凹口1313，滤材12的端部 插接于分水件131的凹口1313内，除此之外，凹口1313内还设有固定柱1314，并且，转轴1311、连接柱1312以及固定柱1314的中心线相重合，固定柱1314插接于中心管121的管道内，从而加强了分水件131与滤材12的固定连接。在此基础上，分水件131还设有连通分水流道与过滤流道的分水件进出水口，具体而言，分水件进出水口包括连通第四进水流道14a与第三进水流道15a的第四进水口154、连通第四出水流道14b与第三出水流道15b的第四出水口155以及连通第四排污流道14c与第三排污流道15c的第四排污口156，其中，第四进水口154设于连接柱1312的侧壁上，第四出水口155设于固定柱1314远离分水件131的一端，第四排污口156设于固定柱1314与分水件131相连接的一端。基于此，第四进水流道14a、第四出水流道14b以及第四排污流道14c被滤材12完全分隔开来了，从而保证了过滤的有效性和完整性，可防止自来水未过滤就排出，提高了过滤的质量。另外，为了便于分水流道的制作形成，转轴1311的顶端设有三个分别与第三进水流道15a、第三出水流道15b以及第三排污流道15c相连通的分水件工艺口1315，并且，三个分水件工艺口1315被同一个分水件堵水盖1316封堵住，以防止漏水。
进一步地，如图8至图10所示，挡水件132远离分水件131的一端设有与挡水流道数量相等且一一对应的凸柱，凸柱包括与第二进水流道16a相对应的进水凸柱164、与第二出水流道16b相对应的出水凸柱165以及与第二排污流道16c相对应的排污凸柱166。在此基础上，挡水件132上还设有与挡水流道相连通的挡水件进出水口，具体而言，挡水件进出水口包括与第二进水流道16a相连通的第一进水口167、与第二出水流道16b相连通的第一出水口168以及与第二排污流道16c相连通的第一排污口169，其中，第一进水口167设于进水凸柱164的顶端，第一出水口168设于出水凸柱165的顶端，第一排污口169设于排污凸柱166的顶端。另外，为了便于挡水流道的制作形成，挡水件132的外侧壁设有三个分别与第二进水流道16a、第二出水流道16b以及第二排污流道16c相连通的挡水件工艺口1324，并且，每个挡水件工艺口1324分别被挡水件堵水盖1323封堵住，以防止漏水。
进一步地，在图2的基础上参见图11，底座流道包括第一进水流道20a、第一出水流道20b以及与第一排污流道20c，当壳体11的第一端旋接于底座2内时，第二进水流道16a对准第一进水流道20a，第二出水流道16b对准第一出水流道20b，第二排污流道16c对准第一排污流道20c，且第二进水流道16a与第一进水流道20a之间、第二出水流道16b与第一出水流道20b之间以及第二排污流道16c与第一排污流道20c之间均设有自动锁水组件22。
进一步地，如图11和图13所示，底座2的凹腔21内设有与底座流道数量相等且一一对应的凹槽23，每个凹槽23均设有自动锁水组件22。凹槽23为阶梯槽，其包括第一级槽位231和第二级槽位232，底座流道设于第二级槽位232的槽底，也即，凹槽23设为三个，第一进水流道20a、第一出水流道20b以及与第一排污流道20c分别设于三个凹槽23的第二级槽位232的槽底。自动锁水组件22包括弹簧221、封水塞222以及封水塞213，封水套223通过超声波焊接或胶水粘接等组装工艺安装于第一级槽位231内，封水塞222设于封水套223内，并且，封水塞222设有防止其从封水套223中弹出的限位裙板2221，弹簧221设于第二级槽位232内并顶住封水塞222，挡水件132的进水凸柱164、出水凸柱165以及排污凸柱166分别伸入各自对应的封水套223内。基于此，在壳体11的第一端向底座2的凹腔21内旋入的过程当中，各凸柱伸入封水套223内，以限制挡水件132的转动，与此同时，进水凸柱164、出水凸柱165以及排污凸柱166分别顶开各自对应的自动锁水组件22的封水塞222，使得第二进水流道16a与第一进水流道20a相连通，第二出水流道16b与第一出水流道20b相连通，第二排污 流道16c与第一排污流道20c相连通。
进一步地，如图13至图14所示，底座2的内侧壁设有第二滑槽24，第二滑槽24延伸至凹腔21的开口边缘，且凹腔21的开口边缘设有第二滑槽24的滑口241，壳体11的外侧壁设有与第二滑槽24相对应的第二凸块116，第二凸块116与第二滑槽24构成转接结构，并且，该转接结构与止水组件13之间存在如下关联：当第二凸块116随着壳体11的转动滑至第二滑槽24的最里端时，说明壳体11的第一端已完全旋入底座2的凹腔21内，与此同时，挡水件132的各凸柱克服弹簧221的弹力将封水塞222完全顶开，使得挡水流道与底座流道相连通；当第二凸块116随着壳体11的转动从滑口241脱离出第二滑槽24时，说明壳体11的第一端已完全旋出底座2的凹腔21，与此同时，挡水件132的各凸柱不再顶住封水塞222，弹簧221利用其回复力将封水塞222顶入封水套223内，使得挡水流道与底座流道断开。
基于上述固定限位结构、滑动限位结构以及转接结构，使用者可以在同时操控止水组件13和自动锁水组件22的基础上实现止水组件13和自动锁水组件22的同步通断。具体而言，在拆下滤芯装置时，使用者旋转壳体11，分水件131与挡水件132发生相对旋转，第一凸块171滑至第一滑槽172的第二端，分水件对接口与挡水件对接口相互错开，止水组件13断水，与此同时，第二凸块116从滑口241脱离出第二滑槽24，壳体11完全旋出底座2的凹腔21，封水塞222被弹簧221顶入封水套223内，自动锁水组件22断水，至此，双向封水结构实现同步断水；相反地，在装入滤芯装置时，使用者旋转壳体11，分水件131与挡水件132发生相对旋转，第一凸块171滑至第一滑槽172的第一端，分水件对接口与挡水件对接口完全对接，止水组件13通水，与此同时，第二凸块116滑至第二滑槽24的最里端，壳体11完全旋入底座2的凹腔21内，封水塞222被挡水件132的凸柱顶出封水套223，自动锁水组件22通水，至此，双向封水结构实现同步通水。
进一步地，如图6和图15所示，为了提高分水件对接口与挡水件对接口之间的密封性，防止转轴1311与转孔1321相对转动时相邻的分水件对接口之间和相邻的挡水件对接口之间出现窜水、漏水的状况，转轴1311与转孔1321之间设有套于转轴1311外部的密封件133，转轴1311的外侧壁设有供密封件133卡入的密封件卡槽1317。具体而言，密封件133包括两根第一筋条1331以及连接于二者之间的多根第二筋条1332，其中，第一筋条1331优选环形，也可选能够围成环形的长条形，相邻两根第二筋条1332与两根第一筋条1331围成一个密封单元格1333，不同的分水件对接口分别位于不同的密封单元格1333内，并且，任意相邻的两个分水件对接口之间至少间隔一个密封单元格1333。基于此，第一筋条1331能够防止转轴1311与转孔1321之间的间隙溢水，而第二筋条1332构成的密封单元格1333则将每个分水件对接口相互隔离开来，并且，随着转轴1311与转孔1321之间的转动，密封单元格1333随着其相应的分水件对接口转动，当分水件对接口与挡水件对接口错开后，分水件对接口溢出的水始终存留于该分水件对接口所在的密封单元格1333内，与此同时，挡水件对接口溢出的水则流入此时该挡水件对接口所对应的密封单元格1333内；而当分水件对接口与挡水件对接口再次对接时，各挡水件对接口溢出的水分别留存于各自相应的密封单元格1333内，不会互相流动、交叉感染。从而，密封件133很好的解决了相邻的分水件对接口之间和相邻的挡水件对接口之间出现窜水、漏水的问题。
本发明提供的滤芯装置的水流走向为：自来水依次经第一进水流道20a、第二进水流道16a、第三进水流道15a以及第四进水流道14a进入过滤腔体111内，经过滤材12过滤后，产生的纯水依次经过第四出水流道14b、第三出水流道15b、第二出水流道16b以及第一出水流道20b流出，产生的废水依 次经过第四排污流道14c、第三排污流道15c、第二排污流道16c以及第一排污流道20c流出。
需要指出的是，本发明提供的滤芯装置可根据需求减少流道，比如只设置进水流道和出水流道，不设置排污流道；另外，本发明提供的滤芯装置主要应用于净水器当中，但也可应用于其他净化技术领域；滤材12可选用RO滤材(反渗透滤材)、PP滤材、活性炭滤材、超滤滤材等。
综上，本发明提供一种滤芯装置，跟现有技术相比，具有如下有益效果：
1、止水组件13能够控制通水和断水，从而能够在滤芯装置的拆下过程中防止过滤腔体111内的残留水流出；
2、自动锁水组件22能够控制滤芯装置与外接管道之间的通水和断水，从而能够在滤芯装置的拆下过程中防止外接管道中的水流溢出；
3、止水组件13采用侧面通断水的方式，简化了组装结构，提升了生产制造的效率，降低了成品的不良率，并且在保证密封性的前提下提高了分水件131与挡水件132相对旋转时的顺滑度，降低了旋转时的顿挫感，具有较好的操控手感；
4、结合固定限位结构、滑动限位结构以及转接结构，使用者只需旋转壳体11即可在同时操控止水组件13和自动锁水组件22的基础上实现止水组件13和自动锁水组件22的同步通断，操作简单便捷；
5、分水件131与滤材12的连接形式独特，进水流道、出水流道以及排污流道被滤材12完全分隔开来，保证了过滤的有效性和完整性，防止自来水未过滤就排出，提高了过滤的质量；
6、分水件131和挡水件132均设有工艺口，便于流道的制作形成；
7、滤芯装置的各零部件结构简单，易于生产和组装，制造成本低。
另外，本发明还提供了一种净水器，由于该净水器采用了上述滤芯装置，因此具有不漏水、不窜水、滤芯更换方便等优点。
