Description

滤芯快速更换装置 技术领域
本发明涉及滤芯快速更换装置，特别是可用于多级过滤系统的滤芯快速更换装置。
背景技术
在化工、生物、生活设备中经常用到多级过滤系统，例如净水器，通常由3-5个串联的滤芯组成，需要过滤的水依次经过串联的滤芯进行过滤。现有的滤芯之间，通常用接头串联。接头和滤芯之间，采用螺纹连接。但传统结构的接头和滤芯组成的系统在使用时具有以下的不足：一是结构复杂，由于零件多导致机构可靠性下降，二是更换滤芯时维护技术要求高，往往需要专业人员来操作；三是在某一滤芯需要更换时，需要先停水或停气，影响系统的工作效率。
发明内容
本发明的目的之一在于提供无需停水情况下即可进行滤芯更换的滤芯快速更换装置。
本发明的另一目的在于提供一种可快速更换滤芯的多级过滤系统。
本发明提供的技术方案如下：
滤芯快速更换装置，其包括：
至少一滤芯单元，其可拆卸地与接头单元固定连接，具有至少一流体进口及至少一流体出口；
至少一接头单元，其具有至少一流体进口及至少一流体出口；所述接头单元包括一接头以及一设于接头内的分水装置，在滤芯单元与接头单元固定连接的位置，所述分水装置将接头单元流体进口中进入的流体接通到滤芯单元的流体进口，将滤芯单元的流体出口接通到接头单元的流体出口，使流体进入接头单元后，先经过滤芯单元再从接头单元的流体出口流出；在滤芯单元脱离接头单元的位置，该分水装置将该接头单元的流体进口和接头单元的流体出口直接连通，使流体进入接头单元后，直接从接头单元的流体出口流出。
在一较佳实施例中，所述接头单元和所述滤芯单元通过卡扣机构连接。
在一较佳实施例中，所述的卡扣机构包括：
位于滤芯单元顶端外侧周壁上的至少一凸起；
至少一位于接头单元内壁和滤芯单元的凸起配合的供该凸起进出的滑槽；以及
位于所述滑槽一侧、和所述滑槽连通的用于卡接凸起的至少一横向卡槽。
在一较佳实施例中，所述接头单元的接头包括一外壳和一套设于该外壳的内筒，外壳和内筒之间有一间隙；所述外壳两侧壁分别设至少一流体进口和至少一流体出口，所述的流体进口和流体出口分别通过一内管和所述内筒的内腔连通；所述内筒包括至少一和外壳的流体进口对应的第一进口，以及至少一和外壳流体出口对应的第一出口，还包括至少一和外壳、内筒的间隙连接的第二出口。
在一较佳实施例中，所述的第一出口位置低于第一进口，第二出口位置高于第一进口。
在一较佳实施例中，所述分水装置套设于所述接头的内筒中，其包括：
一分水轴，其包括一空心轴体、一环绕空心轴体凸设的上凸缘、一环绕空心轴体凸设的下凸缘以及一下轴体，所述的上凸缘和下凸缘与内筒的内壁可滑动地密封连接；以及，
一弹性体，其套设于所述空心轴体的腔内并伸出于该空心轴体的腔。
在一较佳实施例中，还包括一上盖体，其固定于所述外壳的顶端，该上盖板底部具有一用于固定弹簧顶端的柱体；还包括一下盖体，其固定于所述接头的内筒的下端，设有一轴向的通孔。
1、 在一较佳实施例中，所述的滤芯单元包括连接在一起的筒体上盖和筒体下盖，以及一密封于筒体上盖和筒体下盖内的滤芯，所述的筒体上盖顶端外侧周壁上设有至少一凸起，所述凸起的位置与分水轴下轴体的位置相适配。
在滤芯单元与接头单元固定连接的位置时，滤芯单元上的凸起向顶起分水轴，使接头单元流体进口中进入的流体接通到滤芯单元的流体进口，流体进入接头单元后，先经过滤芯单元再从接头单元的流体出口流出；
在滤芯单元脱离接头单元时，接头单元的分水轴在弹性体的作用下向下移动，使接头单元流体进口中进入的流体直接接通到接头单元的流体出口。
一种多级过滤系统，其使用了前述的滤芯快速更换装置。
由上述描述可知，本发明提供了一种滤芯快速更换装置，本发明采用卡扣结构取代了螺纹连接接头，安装和更换都更为快速，简便。由于在接头中采用了分水装置，在滤芯单元卡接至接头单元位置，所述分水装置将接头单元流体进口中进入的流体接通到滤芯单元进口，将滤芯单元的出口接通到接头单元的出口；在滤芯单元脱离接头单元的位置，该分水装置将该接头单元的进口和接头单元的出口直接连接，同时封闭滤芯单元接口。因此，可以在不影响水路的情况下快速更换滤芯，简化了更换滤芯的操作；甚至在取下滤芯之后，不安装滤芯也可保持水路通畅。本发明更换滤芯的工作无需专业人员操作，极大的降低了净水器等多级过滤系统的维护技术要求。

具体实施方式
本发明的具体实施例，参照图1至图7，一种多级过滤系统的滤芯快速更换装置，用于净水器，其包括多个串联的滤芯单元与接头单元。
该滤芯单元包括筒体上盖1、筒体下盖2以及滤芯3。筒体上盖1和筒体下盖2密封连接，滤芯3组装于筒体上盖1与筒体下盖2的组成的空腔内。其中滤芯3的滤嘴32的根部设有一密封圈31；筒体上盖1上部外壁凸设有对称设置的凸起11和12；靠顶端的外壁设有两道凹槽，凹槽内分别设置密封圈13和14。该筒体上盖1的内部套设有一内筒17，内筒与外壁之间形成进水口16，内筒内部形成空腔18，空腔18的上端即为内筒上盖的出水口，内筒的内壁向空腔18内凸设有一用于顶分水轴7的筋条15。内筒17的下端和滤芯3的上端螺旋连接并用密封圈31密封。
该接头单元包括上盖体4、接头5、弹簧6、分水轴7以及下盖体8.
接头包括一外壳50和一套设于该外壳50的内筒53，外壳50和内筒53之间有一间隙501；所述外壳两侧壁分别设一流体进口51和一流体出口52，该流体进口51和流体出口52分别通过一内管和所述内筒的内腔连通；所述内筒53包括一和外壳的流体进口51对应的第一进口531，以及和外壳流体出口52对应的第一出口532，还包括一和外壳、内筒的间隙连接的第二出口533，其中该第一出口532位置低于第一进口531，第二出口533位置高于第一进口531。
该外壳50底部设一滤芯单元接口，其设有一对位于内壁与滤芯单元筒体上盖1的凸起11、12配合的、供该凸起11、12进出的滑槽54、56；以及分别位于所述滑槽54、56一侧与所述滑槽54、56连通的、用于卡接凸起的横向卡槽55、57。
上盖体4密封地焊接在接头5的顶端，上盖体4的底部中央设有一凸柱41，弹簧6的一端套设于该凸柱41上，另一端套入于分水轴7的空心轴体71中。
该下盖体8焊接在接头5的内筒53下端，其中心设有轴向的通孔82，下部外壁设有密封圈81。
弹簧6和分水轴7组成分水装置，其中：
分水轴7密封地设于接头5的内筒53内，其包括一空心轴体71，一环绕空心轴体凸设的上凸缘72、一环绕空心轴体凸设的下凸缘73以及一下轴体78，该上凸缘72沿圆周方向环设一凹槽74，凹槽74内设密封圈75；下凸缘73沿圆周方向环设一凹槽76，凹槽76内设密封圈77。
参见图6和图7，未接入滤芯系统时，位于接头5内筒53内的分水轴7的上凸缘72密封地设于第二出口533与第一进口531之间，下凸缘73密封地设于通孔82与第一出口532之间，此时，水流从进口51进入，从第一进口531流入内筒53内，由于该内筒53的上下端分别被分水轴7的上、下凸缘72和73密封，水流直接从上、下凸缘之间的空间流过，再从内筒53的第一出口532流出，从外壳的出口52流出进入下一单元。
同时参见图8至图10。接入滤芯系统后，筒体上盖1内的筋条15将分水轴7的下轴78向上顶起，弹簧6被压缩，上凸缘72的位置高于内筒53的第二出口533，而下凸缘73密封地卡于第一进口531与第一出口532之间。此时，水流从进口51，再从第一进口531进入内筒53，由于下凸缘73密封地卡于第一进口531与第一出口532之间，而上凸缘72的位置高于内筒53的第二出口533，因此水流从第二出口533流出，进入内筒53和外壳50之间的空隙501，再进入筒体上盖的进口16，之后进入滤芯3过滤，从滤芯3的顶端的出口进入筒体上盖的出水口18，再从下盖体8的通孔82内，最后经第一出口532流到出口52，进入下一单元。
当需要替换滤芯时，只需旋转筒体上盖1，使筒体上盖1的凸起11、12分别从接头5的横向卡槽55、57滑到滑槽54、46中，整个滤芯单元即可脱离接头单元。此时，弹簧舒展，推动分水轴5向下移动，位于接头5内筒53内的分水轴7的上凸缘72又重新密封地设于第二出口533与第一进口531之间，下凸缘73也密封地设于通孔82与第一出口532之间，即又回到了图7中的状态，此时从第一进口531流入内筒53内的水流又可直接从上、下凸缘之间的空间流过，再从内筒53的第一出口532流出。
上述仅为本发明的一个具体实施例，但本发明的设计构思并不局限于此，凡利用此构思对本发明进行非实质性的改动，均应属于侵犯本发明保护范围的行为。
工业实用性
本发明滤芯快速更换装置，设计合理、结构简单，可以在不影响水路的情况下快速更换滤芯，简化了更换滤芯的操作；甚至在取下滤芯之后，不安装滤芯也可保持水路通畅。
