Description

带旋转阀的过滤器 技术领域
本发明涉及一种水净化器，特别涉及一种带旋转阀的过滤器组件。
背景技术
CN200680000463.1 公开了一种 ' 水净化过滤组件 ' , 它的目的是提供一种减少更换新滤筒所需时间，并能容易进行更换的水净化器的过滤组件。该技术方案: 所述用于水净化器的过滤组件，具有：头部，其包括用于引导流入水的进水管、用于控制水流进入到所述进水管的控制阀、以及用于将净化后的水排放到外部的出水管；圆形帽，设置在所述头部的下部并且在其内部具有圆柱形空间；过滤器帽，安装到所述圆柱形空间内，并且具有供水流入其中的进水孔、以及用于排水的排水孔；滤筒，其具有过滤部件，所述过滤部件设置有过滤器以净化水，所述过滤组件包括：多个第一紧固孔，形成在所述圆形帽的外圆周上，并且均具有梯级；锁定部件，设置在各个所述第一紧固孔中，从而锁定所述滤筒；弹性构件，设置成围绕所述圆形帽和所述锁定部件，并且弹性地使所述锁定部件维持在相应的第一紧固孔中；以及多个第二紧固孔，形成在所述过滤器帽上部的外圆周上，用于将所述锁定部件安装到各个所述第二紧固孔中。其不足之处是: 当使用者要更换过滤介质筒时，正常是旋转滤筒40小于90度的位置向下一拉，滤筒才会脱落，如果使用者旋转滤筒40等于90度或者是180度时，锁定部件50又弹回到过滤帽30中的紧固孔33中，过滤帽30又被锁死，滤筒就取不下来了，很容易让人迷惑，所以此发明缺少一个取滤筒时旋转的限位过程2，当取下滤筒40后，由于出水管12处没有装截水装置，如果出水管12连接的引水管很长，并且过滤介质筒位置低时，进水管中的水会全部倒流而出，如果水很多时，对过滤介质筒安装位下面会造成一定影响，因此还缺少一个针对出水位置截水的过程。
技术问题

 有益效果
与现有技术相比，本发明的优点：

4、该过滤组件不仅减少了更换滤筒的时间，更能让用户能自己轻而易举地更换。同时，通过卸取滤筒过程中的旋转，过滤组件中的装置能够自动将进水方向和出水方向的水源关闭，免去用户预先要关闭进(出)水阀的麻烦。而且过程中能够将旋转阀表面弧形密封圈内的残留水通过进出水口或排放孔排放掉(但整个更换滤筒过程中不会留洒太多水)，避免残留水成死水，减少二次污染。

 本发明的最佳实施方式
本发明下面将结合附图作进一步详述：
图1～图19、图26～图29示出了本发明的第一个实施例。
请参阅图1所示，所述带旋转阀的过滤器，包括滤筒1，所述滤筒1的开口部固设具有悬伸颈部111的芯体部11，芯体部颈部111上通过支撑元件2连接头部组件3，头部组件3的轴向腔室31与滤筒芯体部颈部111之间套装旋转阀组件4，头部组件轴向腔室31径向开设一对管接头32，管接头32上密封连接进水管321和出水管322，头部组件轴向腔室31的开口端设封闭盖组件5。
请参阅图6、图7所示，所述滤筒1由筒体12、筒体12开口部固设的芯体部11、芯体部11上开设用于将未过滤液体引导至筒体12内的引入通道13、用于将已过滤液体引导离开筒体12内的引出通道14、芯体部颈部111外壁沿径向对称设置用于锁定悬挂和旋脱滤筒1并引导旋转阀来开通和关闭进、出水口而向外悬伸的一对耳柄112、与芯体部11配合的过滤介质组件16组成。
请参阅图1、图6、图9、图10、图26～图28所示，所述芯体部11由与筒体12密封连接似瓶口及瓶肩形状的颈部111、颈部111自外向内沿轴心凸伸筒体12内腔中的管状体15、管状体15的外圆部与颈部111中心孔通过筋位连通形成的耳舌定位槽18，颈部111外壁径向凸设的一对耳柄112，耳柄112的左、右侧面设置的左导向斜面115、右导向斜面116，颈部端口、管状体端口、管状体底端处分别设置的过滤介质进水密封圈113、过滤介质出水密封圈114、过滤介质套筒密封圈17，芯体部下端部外圆R角处设置用于与头部组件3外圆底部的定位标识线317安装定位的三角形定位标识117、管状体15套装过滤介质组件16、颈部上贯通开设与管状体15平行的引入通道13组成。
请参阅图6所示，所述过滤介质组件16由套筒164、与套筒164螺旋紧固的套筒旋盖161、套筒164内腔螺纹端与套筒旋盖161配合压封的过滤织物163（可以是棉、布、滤纸等的总称）、包覆压紧在过滤织物163顶面的过滤织物压盖162、套筒164内装入的过滤介质，套筒旋盖161顶部沿圆心部位凹设供芯体部11的管状体15装入其内的一段盲孔1611组成。套筒164内腔套装有过滤介质，套筒164内腔螺纹端压封的过滤织物163和过滤织物压盖162通过套筒旋盖161与套筒164螺旋紧固。过滤织物的使用，是为了阻止一些过滤介质本身的颗粒随过滤后的水流出；套筒的使用，是为了将未过滤介质引导到过滤介质的下端，使水能通过尽可能多的介质，得到充分过滤，这样也延缓了过滤介质的使用寿命。上述与套筒164螺旋紧固套筒旋盖161的连接方式，也可以采用卡扣或焊接紧固。
请参阅图1所示，过滤介质组件16构造为：保证流体处理系统与可更换的滤筒1相结合，并且流体处理系统与滤筒1有内在的关系。除此以外旋转阀组件4和滤筒1设有保证滤筒1顺时针旋转时的限位结构，这样可以告诉使用者在什么位置时滤筒1装到位了。
请参阅图1～图5、图7、图28所示，头部组件3由上、下贯通的轴向腔室31和外部型腔318、轴向腔室31顶部外壁对应凸设的旋转阀轴向旋转定位块314、轴向腔室31分别对称在中部沿径向向外扩展至外部型腔318的结合腔33、轴向腔室31与结合腔33交合处设置的导向筋位315、结合腔33端部分别开设带有固定爪323的管接头32、分别密封连接于管接头32的进水管321和出水管322、轴向腔室31的底部分别沿轴向凹设供支撑元件紧固的螺孔311、外部型腔318的外壁成型的挂架34、挂架34上设置的安装孔341、轴向腔室31底端外壁对应的相反角度位置分别凸设的滤筒轴向旋转锁定定位块312、轴向腔室31底端外壁对应的相反角度位置分别凸设的滤筒轴向旋转脱离的头部导向斜面316、外部型腔318外圆底部的长方形定位条317组成。
请参阅图1、图7、图11～图19所示，所述旋转阀组件4由阀体41、阀体41一端端口分别对称沿径向向外凸伸的一段环状定位块42，而使二定位块42相对端对称成型的轴向旋转定位缺口43、阀体41另一端端口分别对称沿轴向向外凸伸用于插接在滤筒颈部耳舌定位槽18内的耳舌44、阀体41外圆周表面分别对称凹设旋转阀密封圈固定凹槽452、分别置入旋转阀密封圈固定凹槽452内的旋转阀密封圈46、旋转阀密封圈46一侧分别通往阀体41内腔与管状内腔圆形的开口、阀体41内腔成型的管状内腔、管状内腔中轴向设有顶端封闭而底端开口的倒置杯状体47、管状内腔位于中间部位分别沿径向凸伸连接于倒置杯状体47封闭端的连接臂48组成。所述旋转阀密封圈固定凹槽452的一侧凹设与管状内腔贯通的通孔(图中未示)，而旋转阀密封圈固定凹槽452的另一侧则覆盖圆形密封垫/圈463。旋转阀组件4的阀体41和旋转阀密封圈46二者采用了包胶注塑成型的工艺制成，也可以是独立嵌入密封圈的安装方式，使旋转阀密封圈46固定在阀体41的旋转阀密封圈固定凹槽452内并成为一体。并使旋转阀组件4在头部组件3的轴向腔室31内，经阀体41的耳舌44与滤筒1上的芯体部11开口端的耳舌定位槽18相互插接旋转配合(参见图9～图12、图14～图19)；在打开的位置，允许未过滤的流体通过阀体41的引入通道13经过滤筒1从阀体41的引出通道14排出成为过滤后的流体(参见图6、图7)；在关闭的位置，阀体41上的旋转阀密封圈46对应与弧形密封圈461通过筋位连接的圆形密封垫/圈463；便于将头部组件3的轴向腔室31上的进水口和出水口封闭，使圆形密封垫/圈463与头部组件上轴向腔室31面中端的径向通孔同心，以此限制未过滤的流体经过过滤介质组件16（参见图8）。
请参阅图1、图7～图8所示，所述封闭盖组件5由与头部组件3轴向腔室31顶部螺纹313连接的旋转阀固定压盖51、通过卡扣521安装在头部组件轴向腔室31顶部连接的旋转阀固定压盖51插槽(图中未示)内的装饰盖52组成。
请参阅图1、图4、图9～图13所示，所述支撑元件2由设于头部组件3与滤筒1之间且套入滤筒芯体部颈部耳柄112后旋转定位的滤筒锁定法兰21、将滤筒锁定法兰21与头部组件3轴向腔室31的底部分别沿轴向凹设供支撑元件紧固的螺孔311连接的固定螺丝22组成；所述滤筒锁定法兰21由法兰体21上开设用于接纳滤筒颈部111的通孔211、通孔211取对称端分别凹扩用于过滤介质悬挂与滤筒耳柄112前斜面导向作用的左、右斜面212、法兰体21上开设的螺孔213组成。支撑元件2经过滤介质组件16、滤筒锁定法兰21压接在头部组件3的轴向腔室31的底部，并分别沿轴向凹设供支撑元件2紧固的螺孔311的底面上，然后，用固定螺丝22穿过滤筒锁定法兰21上的法兰体螺孔213锁紧在头部组件3的轴向腔室31的底部分别沿轴向凹设螺孔311的底面上，支撑元件2则固定在头部组件3上，提供滤筒1的悬挂锁定功能。
请参阅图1、图6、图7所示，所述带旋转阀的过滤器组件构造为与流体处理系统一起使用的，该流体处理系统包括用于将未过滤的处理流体引导到过滤器组件的引入通道13和用于从过滤组件引导已过滤的处理流体的引出通道14。此过滤组件通过头部组件外部型腔318的外壁成型的挂架34上设置的安装孔341，安装到放置的相应支撑结构上。
工作原理：正常状态下，过滤介质组件16针对滤筒1的芯体部11悬伸的颈部111对应的两个耳柄112，先穿过支撑元件2的滤筒锁定法兰21上的法兰体通孔211(参见图9、图10)，此时旋转阀组件4上的阀体41另一端端口向外凸伸的耳舌44会插入筒体1中管状体15的外圆部与颈部111圆心部位并通过筋位连通形成的耳舌定位槽18中(参见图10)。
顺时针旋转滤筒1，此时滤筒1上的芯体部11向外凸伸的耳柄112对应的右导向斜面116，与支撑元件2上的滤筒锁定法兰21对应的斜面212作相对运动，滤筒1会向上延伸悬挂在过滤介质锁定法兰21上（参见图29）。
顺时针旋转90度时，滤筒1芯体部11的耳柄112与头部组件3轴向腔室31底端外壁对应的相反角度位置分别凸设的滤筒轴向旋转锁定定位块312碰死(参见图12、图29)，致使头部组件3上的外部型腔318、外圆底部的长方形定位条317与滤筒1芯体部11下端部的三角形定位标识117对齐(参见图26)，告诉使用者，已安装到位。
当滤筒1向上延伸悬挂在滤筒锁定法兰21时，向上的力会促使滤筒1上的芯体部11对应的颈部端口和管状体端口凹槽内的过滤介质进水密封圈113、过滤介质出水密封圈114与旋转阀组件3上的阀体41对应的倒置杯状体47内腔过盈密封(参见图1、图6)。
出厂设置状态的旋转阀组件4是关闭的(参见图8)，阀体41外圆周表面的旋转阀密封圈固定凹槽452内的弧形密封圈461、弧形密封圈461内并与其相连的圆形密封垫或圆形密封463与头部组件3的轴向腔室31跟着旋转阀组件4相对旋转运动并且过盈密封，圆形密封垫或圆形密封463在弧形密封圈461内，阀体41不导通一边的圆形密封垫或圆形密封463与头部组件上轴向腔室31面中端的径向通孔同心，此时处于关闭状态，即：关掉了进水口也关闭了出水口(参见图8)；如果圆形密封垫/圈463对应的另一端 (阀体41导通的一侧)与头部组件上轴向腔室41面中端的径向通孔同心，此时处于导通状态，即：未过滤流体直接通过进水管321和过滤介质组件16从出水管322排出(参见图7)，当滤筒1顺时针旋转90度后，旋转阀组件4上的阀体41对应的耳舌44会跟着滤筒1上的耳舌定位槽18旋转90度，由于受到头部组件3轴向旋转锁定定位块312与滤筒1耳柄112的限制定位和旋转阀组件4阀体41一端端口的轴向旋转定位缺口43与头部组件3旋转阀轴向旋转定位块314限制定位，旋转阀组件4只能旋转90度，此时，位于阀体41导通一侧的圆形密封垫或圆形密封463的另一端与头部组件的轴向腔室41面中端的径向通孔同心，则旋转阀组件4处于导通状态(参见图6、图7、图11)，未过滤的流体依次经过进水管321、管接头32、头部组件3的结合腔33、旋转阀组件4的引入通道13、滤筒1、旋转阀组件4的引出通道14、头部组件3的结合腔33、管接头32、出水管322(参见图6～图7)排出去的就是过滤后的流体。
请参阅图8～图10所示，更换滤筒1，滤筒1逆时针旋转90度，由于旋转阀组件4上的阀体41另一端端口分别对称轴向向外凸伸的耳舌44，插入筒体1中管状体15的外圆部与颈部111圆心部位通过筋位连通形成的耳舌定位槽18中(参见图9、图10)，旋转阀组件4的阀体41一端端口的轴向旋转定位缺口43与头部组件3上的轴向腔室31顶部外壁对应凸设的旋转阀轴向旋转限位块314限制定位，致使旋转阀组件4也逆向旋转90度，此时，旋转阀组件4已将进水管321引入的未过滤流体关闭，阀体41外圆周表面的密封圈固定凹槽452内的弧形密封圈461、弧形密封圈461设有一个与弧形密封圈461连接的圆形密封垫/圈463，与头部组件3上的轴向腔室31跟着旋转阀组件4相对旋转运动并且过盈密封，圆形密封垫/圈463设在弧形密封圈461内部，圆形密封垫/圈463 (阀体41不导通的一侧)与头部组件上轴向腔室41中端的径向通孔同心，此时，处于关闭状态，即：圆形密封垫/圈463关掉了头部组件3的进水口，也关闭了头部组件3的出水口(参见图8)。
滤筒逆向旋转90度后限制定位，继续逆向旋转滤筒1，并通过滤筒1芯体部11向外凸伸的耳柄112对应的左导向斜面115与头部组件3的轴向腔室31底端外壁对应的相反角度位置分别凸设的滤筒轴向旋转脱离的头部导向斜面316作相对运动(参见图28)，由于耳柄左导向斜面115向下的作用力，会促使滤筒1上的芯体部11对应的颈部端口和管状体端口凹槽内的过滤介质进水密封圈113、过滤介质出水密封圈114与旋转阀组件3上的阀体41对就应的倒置杯状体47的内腔脱离(参见图28)，这时滤筒1芯体部11向外凸伸的耳柄112与支撑元件2的滤筒锁定法兰21上的法兰体通孔211同心(参见图10)，滤筒1上的芯体部11向外凸伸的耳柄就失去了悬挂在支撑元件2上滤筒锁定法兰21上的作用面，滤筒1脱离(参见图28)。
当取下滤筒1时，阀体41不导通一侧的圆形密封垫/圈463与头部组件上轴向腔室41中端的径向通孔同心，旋转阀组件4已将进水管321引入的未过滤流体关闭(参见图8)，弧形密封圈461和圆形密封垫/圈463之间残留的死水在进、出水口与弧形密封圈区域内是导通的，所以卸去滤筒时，残留水可以直接通过进、出水口排出(参见图14～图15)。

请参阅图1所示，过滤介质组件16构造为：保证流体处理系统与可更换的滤筒1相结合，并且流体处理系统与滤筒1有内在的关系。除此以外旋转阀组件4和滤筒1设有保证滤筒1顺时针旋转时的限位结构，这样可以告诉使用者在什么位置时滤筒1装到位了。
请参阅图1～图5、图7、图28所示，头部组件3由上、下贯通的轴向腔室31和外部型腔318、轴向腔室31顶部外壁对应凸设的旋转阀轴向旋转定位块314、轴向腔室31分别对称在中部沿径向向外扩展至外部型腔318的结合腔33、轴向腔室31与结合腔33交合处设置的导向筋位315、结合腔33端部分别开设带有固定爪323的管接头32、分别密封连接于管接头32的进水管321和出水管322、轴向腔室31的底部分别沿轴向凹设供支撑元件紧固的螺孔311、外部型腔318的外壁成型的挂架34、挂架34上设置的安装孔341、轴向腔室31底端外壁对应的相反角度位置分别凸设的滤筒轴向旋转锁定定位块312、轴向腔室31底端外壁对应的相反角度位置分别凸设的滤筒轴向旋转脱离的头部导向斜面316、外部型腔外圆底部的长方形定位条317组成。
请参阅图1、图7、图11、图13、图20～图25所示，所述旋转阀组件4由阀体41、阀体41一端端口分别对称沿径向向外凸伸的一段环状定位块42，而使二定位块42相对端对称成型的轴向旋转定位缺口43、阀体41另一端端口分别对称沿轴向向外凸伸用于插接在滤筒颈部耳舌定位槽18内的耳舌44、阀体41外圆周表面密封圈凹槽452、密封圈凹槽452中央部位凹设的残留水排放孔451、分别置入密封圈凹槽452内的旋转阀密封圈46、旋转阀密封圈46一侧分别通往阀体41内腔与管状内腔圆形的开口、阀体41内腔成型的管状内腔、管状内腔中轴向设有顶端封闭而底端开口的倒置杯状体47、管状内腔位于中间部位分别沿径向凸伸连接于倒置杯状体47封闭端的连接臂48、管状内腔下半部分的侧壁上开设有与进水管321连通后垂直转入与轴向腔室31平行的引入通道13、供滤筒芯体部11与管接头32的出水管322连通且垂直连通出水管322的引出通道14组成。所述旋转阀密封圈46由贴合于旋转阀阀体41外圆周表面分别对称凹设在旋转阀密封圈固定凹槽452内的弧形密封圈461、弧形密封圈461内的两侧区域分别设有与弧形密封圈461连接的环形密封圈462组成；而旋转阀密封圈固定凹槽452不导通的一侧设有圆形密封垫/圈463，使旋转阀组件4便于在打开位置和关闭的位置之间相对于头部组件3的轴向腔室31内旋转，在打开的位置，流体就通过过滤介质组件16；在关闭的位置，阻挡流体经过该过滤介质组件16。请参阅图1、图20～图25所示，旋转阀组件4的阀体41和旋转阀密封圈46二者采用了包胶注塑成型的工艺制成，也可以是独立密封圈嵌入安装方式，使旋转阀密封圈46固定在阀体41的旋转阀密封圈固定凹槽452内并成为一体。使旋转阀组件4在头部组件3的轴向腔室31内，通过阀体41的耳舌44与滤筒1上的芯体部11开口端的耳舌定位槽18相互插接旋转配合(参见图9～图12、图20～图25)，在打开的位置，允许未过滤的流体通过阀体41的引入通道13经过滤筒1从阀体41的引出通道14排出成为过滤后的流体(参见图6～图7)；在关闭位置，阀体41上的旋转阀密封圈46位于阀体41不导通一侧的右侧的圆形密封垫/圈463，将头部组件3的轴向腔室31上的进水口和出水口封闭，圆形密封垫/或圆形密封圈463与头部组件上轴向腔室31面中端的径向通孔同心，以此来限制未过滤的流体经过过滤介质组件16(参见图8)。
请参阅图1、图7～图8所示，所述封闭盖组件5由与头部组件3轴向腔室31顶部螺纹313连接的旋转阀固定压盖51及旋转阀固定压盖螺纹511、通过卡扣521安装在头部组件轴向腔室31顶部连接的旋转阀固定压盖51插槽(图中未示)内的装饰盖52组成。
请参阅图1、图4、图9～图13所示，所述支撑元件2由设于头部组件3与滤筒1之间且套入滤筒芯体部颈部耳柄112后旋转定位的滤筒锁定法兰21、将滤筒锁定法兰21与头部组件3轴向腔室31的底部分别沿轴向凹设供支撑元件紧固的螺孔311连接的固定螺丝22组成；所述滤筒锁定法兰21由法兰体21上开设用于接纳滤筒颈部111的通孔211、通孔211取对称端分别凹扩用于过滤介质悬挂与滤筒耳柄112前斜面导向作用的左、右斜面212、法兰体21上开设的螺孔213组成。请参阅图1、图9～图13所示，支撑元件2通过过滤介质组件16、滤筒锁定法兰21压接在头部组件3的轴向腔室31的底部分别沿轴向凹设供支撑元件2紧固的螺孔311的底面上，然后，用固定螺丝22穿过滤筒锁定法兰21上的法兰体螺孔213锁紧在头部组件3的轴向腔室31的底部分别沿轴向凹设螺孔311的底面上，支撑元件2则固定在头部组件3上，提供滤筒1的悬挂锁定功能。
请参阅图1、图6、图7所示，该带旋转阀的过滤器组件构造为与流体处理系统一起使用，该流体处理系统包括用于将未过滤的处理流体引导到过滤器组件的引入通道13和用于从过滤组件引导已过滤的处理流体的引出通道14。此过滤组件通过头部组件外部型腔318的外壁成型的挂架34上设置的安装孔341，安装到放置的相应支撑结构上。
工作原理：正常状态下，过滤介质组件16针对滤筒1的芯体部11悬伸的颈部111对应的两个耳柄112，先穿过支撑元件2的滤筒锁定法兰21上的法兰体通孔211(参见图9、图10)，此时，旋转阀组件4上的阀体41另一端端口向外凸伸的耳舌44会插入筒体1中管状体15的外圆部与颈部111圆心部位通过筋位连通形成的耳舌定位槽18中(参见图10)。
顺时针旋转滤筒1，此时，滤筒1上的芯体部11向外凸伸的耳柄112对应的右导向斜面116，与支撑元件2的滤筒锁定法兰21对应的斜面212作相对运动，滤筒1会向上延伸悬挂在过滤介质锁定法兰21上（参见图29）。
顺时针旋转90度时，滤筒1芯体部11的耳柄112与头部组件3上轴向腔室31底端外壁对应的相反角度位置分别凸设的滤筒轴向旋转锁定定位块312碰死(参见图12、图29)，致使头部组件3上的外部型腔318、外圆底部的长方形定位条317与滤筒1上芯体部11下端部的三角形定位标识117对齐(见图26)，告诉使用者，已安装到位。
当滤筒1向上延伸悬挂在滤筒锁定法兰21时，向上的力会促使滤筒1上的芯体部11对应的颈部端口和管状体端口凹槽内的过滤介质进水密封圈113、过滤介质出水密封圈114与旋转阀组件3上的阀体41对应的倒置杯状体47的内腔过盈密封(参见图1、图6)。
出厂设置状态的旋转阀组件4是关闭的(参见图 8)，阀体41外圆周表面密封圈固定凹槽452内的弧形密封圈461、环形密封圈462与头部组件3的轴向腔室31跟着旋转阀组件4相对旋转运动并过盈密封，环形密封圈462在弧形密封圈461内部，圆形密封垫或圆形密封圈463与头部组件上轴向腔室41面中端的径向通孔同心，此时处于关闭状态，即：关掉了进水口也关闭了出水口(参见图8)；如果环形密封圈462与头部组件上轴向腔室41面中端的径向通孔同心，此时处于导通状态，即：未过滤流体直接通过进水管321和过滤介质组件16从出水管322排出(参见图7)；当滤筒1顺时针旋转90度后，旋转阀组件4上的阀体41对应的耳舌44会跟着滤筒1的耳舌定位槽18旋转90度，由于受到头部组件3轴向旋转锁定定位块312与滤筒1耳柄112限制定位和旋转阀组件4上的阀体41一端端口的轴向旋转定位缺口43与头部组件3旋转阀轴向旋转定位块314的限制定位，旋转阀组件4只能旋转90度，此时，环形密封圈462(阀体41导通的一侧)与头部组件上轴向腔室41面中端的径向通孔同心，旋转阀组件4处于导通状态(参见图6、图7、图11)，未过滤的流体依次经过进水管321、管接头32、头部组件3的结合腔33、旋转阀组件4引入通道13、滤筒1、旋转阀组件4引出通道14、头部组件3结合腔33、管接头32、出水管322(参见图6～图7)排出去的就是过滤后的流体。
请参阅图8～图10所示，更换滤筒1过程：滤筒1逆时针旋转90度，由于旋转阀组件4上的阀体41另一端端口分别对称轴向向外凸伸的耳舌44，插入筒体1中管状体15的外圆部与颈部111圆心部位通过筋位连通形成的耳舌定位槽18中(参见图9、图10)，旋转阀组件4上的阀体41一端端口的轴向旋转定位缺口43与头部组件3上的轴向腔室31的旋转阀轴向旋转限位块314限制定位，致使旋转阀组件4也逆向旋转90，此时，旋转阀组件4已将进水管321引入的未过滤流体关闭，阀体41外圆周表面的密封圈固定凹槽452内的弧形密封圈461、弧形密封圈461内一侧区域的环形密封圈462、弧形密封圈461内另一侧区域的圆形密封垫或圆形密封圈463与头部组件3上的轴向腔室31跟着旋转阀组件4相对旋转运动并且过盈密封，环形密封圈462在弧形密封圈461内部，圆形密封垫或圆形密封圈463与头部组件上轴向腔室41中端的径向通孔同心，此时，处于关闭状态，即：圆形密封垫或圆形密封圈463关掉了头部组件3的进水口，也关闭了头部组件3的出水口(参见图8)。
滤筒1逆向旋转90度后已限制定位，继续逆向旋转滤筒1并通过滤筒1的芯体部11向外凸伸的耳柄112对应的左导向斜面115与头部组件3上的轴向腔室31底端外壁对应的相反角度位置分别凸设的滤筒1轴向旋转脱离的头部导向斜面316作相对运动(参见图28)，由于头部导向斜面316向下的作用力，促使滤筒1上的芯体部11对应的颈部111端口和管状体端口凹槽内的过滤介质进水密封圈113、过滤介质出水密封圈114与旋转阀组件3上的阀体41对就应的倒置杯状体47的内腔脱离(参见图28)，这时滤筒1上的芯体部11向外凸伸的耳柄112与支撑元件2的滤筒锁定法兰21上的法兰体通孔211同心(参见图10)，滤筒1上的芯体部11向外凸伸的耳柄112就失去了悬挂在支撑元件2上滤筒锁定法兰21上的作用面，滤筒1就脱离了(参见图28)。
当取下滤筒1时，圆形密封垫或圆形密封圈463与头部组件上轴向腔室31中端的径向通孔同心，旋转阀组件4已将进水管321引入的未过滤流体关闭(参见图8)，阀体41外圆侧面的密封圈固定凹槽452中央部位设置的残留水排放通孔451会将阀体41外圆周表面的旋转阀密封圈固定凹槽452内的弧形密封圈461、弧形密封圈461内一侧区域设有与弧形密封圈461连接的环形密封圈462与另一侧区域设有与弧形密封圈461连接的圆形密封垫或圆形密封圈463之间残留的死水排掉，弧形密封圈461、环形密封圈462和圆形密封垫或圆形密封圈463之间残留的死水在头部组件3的轴向腔室31与阀体41上的残留水排放通孔451是导通的，所以卸去滤筒时，残留水可以直接通过阀体41上的残留水排放通孔451排出(参见图20～图21)。
以上所述仅为本发明的较佳实施例，凡依本发明权利要求范围所做的均等变化与修饰，皆应属本发明权利要求的涵盖范围。
