如图2、3、9所示，分水阀101包括阀芯10。阀芯10包括壳体1、转轴2、切换组件3和拨动件7。转轴2和切换组件3均设置在壳体1内。
参照图4、5，壳体1包括直管11、隔板13和底座12。直管11可以为圆管形。直管11包括第一管段111和第二管段112。第一管段111和第二管段112同轴设置。第一管段111的一端连接于第二管段112的一端。第一管段111的管壁上还设置有条槽113，该条槽113径向贯穿第一管段111的管壁。该条槽113在管壁上沿直管11的周向延伸。该条槽113设置在靠近第一管段111背离第二管段112的一端。第二管段112的管壁上设置有进水口114。该进水口114径向贯穿第二管段112的管壁。该进水口114可以设置于该第二管段112的中部区域。该进水口114可以是大致方形的开口。隔板13为平板。隔板13设置在直管11内，且位于第一管段111和第二管段112之间。隔板13垂直于直管11的轴线。如图5、15所示，隔板13上具有孔道133和第一轴孔131。孔道133和第一轴孔131均垂直贯穿隔板13。第一轴孔131与直管11同轴设置。孔道133设置在第一轴孔131的一侧。
如图7所示，底座12构造可以为大致的圆盘形。底座12上设置有第一出水口121和第二出水口122。第一出水口121和第二出水口122均垂直贯穿底座12。底座12覆盖在第二管段112背离隔板13的一端的端部上。底座12垂直于直管11的轴线。底座12与第二管段112之间可以是可拆卸连接，例如卡扣连接或螺纹连接。
如图8所示，转轴2包括空心轴段21和实心轴段22。实心轴段22的外径小于空心轴段21的外径。空心轴段21与实心轴段22同轴设置。空心轴段21的一端连接于实心轴段22的一端。空心轴段21内具有一流道，该流道在空心轴段21靠近实心轴段22的一端具有一个端口212，该流道在空心轴段 21背离实心轴段22的一端具有第三出水口211。
转轴2与直管11同轴设置。空心轴段21位于第一管段111内。空心轴段21与第一管段111间隙配合。在空心轴段21与第一管段111之间的密封可以为轴密封。空心轴段21在第一管段111内能绕自身轴线转动。如图5、11所示，空心轴段21与隔板13之间相互分开，空心轴段21与隔板13之间形成一个环空腔室210，该环空腔室210将孔道133和空心轴段21上的端口212相连通。实心轴段22从第一管段111穿过隔板13上的第一轴孔131插入到第二管段112。

切换组件3设置在第二管段112内。如图3所示，切换组件3包括第一密封垫31、第二密封垫35、第一转座32、第二转座34和第一弹性件33。第一密封垫31和第二密封垫35可以是柔性垫片，例如橡胶垫。第一密封垫31、第二密封垫35、第一转座32和第二转座34都套装在实心轴段22上。第一密封垫31、第二密封垫35、第一转座32和第二转座34均与实心轴段22形成连接，第一密封垫31、第二密封垫35、第一转座32和第二转座34在实心轴段22转动时跟随转动。第一密封垫31、第二密封垫35、第一转座32和第二转座34还可以分别与实心轴段22进行平键连接或花键连接。第一弹性件33可以是螺旋弹簧、波纹管或蝶形弹簧。
如图3-5所示，第一密封垫31覆盖在隔板13上，第二密封垫35覆盖在底座12上。第一转座32和第二转座34设置在第一密封垫31和第二密封垫35之间。第一转座32抵靠第一密封垫31，第二转座34抵靠第二密封垫35。第一弹性件33可以是套在实心轴段22上。第一弹性件33位于第一转座32和第二转座34之间。第一弹性件33的相对两端分别抵接于第一转座32和第二转座34，第一弹性件33处于压缩状态。第一弹性件33对第一转座32施 加一个指向隔板13的弹力以使得第一转座32将第一密封垫31紧压在隔板13上，第一弹性件33对第二转座34施加一个指向底座12的弹力使得第二转座34将第二密封垫35紧压在底座12上。
如图4所示，第二管段112上的进水口114位于第一转座32和第二转座34之间，进水口114连通于第一转座32和第二转座34之间形成的腔室。
如图16所示，第一密封垫31上设置有第一通孔314。第一通孔314轴向贯穿第一密封垫31。第一通孔314到转轴2轴线的距离等于隔板13的孔道133到转轴2轴线的距离，这样，第一通孔314可以与孔道133相接通。如图18所示，第一转座32上设置有第二通孔322。第二通孔322轴向贯穿第一转座32。第一通孔314与第二通孔322相互对齐。

从阀芯10的侧面推动拨动件7沿条槽113滑动，拨动件7带动转轴2转动，转轴2转动时能带动切换组件3整体转动，使得切换组件3能切换阀芯10中的水路。
如图10、11所示，在切换组件3转动到第一密封垫31上的第一通孔314和隔板13上的孔道133对齐的第一位置时，从进水口114注入的水流能依次通过第二通孔322、第一通孔314、孔道133、环空腔室210、端口212、空心轴段21内的流道而到达第三出水口211。此时，第二密封垫35上的第三通孔354与底座12上的第一出水口121和第二出水口122相互错开，第二密封垫35封闭第一出水口121和第二出水口122。
如图12、13所示，在切换组件3转动到第二密封垫35上的第三通孔354和底座12上的第一出水口121对齐的第二位置时，从进水口114注入的水流能依次通过第四通孔342、第三通孔354而到达第一出水口121。此时，第二密封垫35上的第三通孔354与底座12上的第二出水口122相互错开，第二 密封垫35封闭第二出水口122，同时，第一密封垫31上的第一通孔314与隔板13上的孔道133相互错开，第一密封垫31封闭隔板13的孔道133。
如图14、15所示，在切换组件3转动到第二密封垫35上的第三通孔354和底座12上的第二出水口122对齐的第三位置时，从进水口114注入的水流能依次通过第四通孔342、第三通孔354而到达第二出水口122。此时，第二密封垫35上的第三通孔354与底座12上的第一出水口121相互错开，第二密封垫35封闭第一出水口121，同时，第一密封垫31上的第一通孔314与隔板13上的孔道133相互错开，第一密封垫31封闭隔板13的孔道133。
由此，通过滑动拨动件7转动切换组件3，能将进水口114选择性地仅与第一出水口121、第二出水口122和第三出水口211中的任意一个相接通，实现分水。
在本申请实施例中，分水阀101的进水口114通过龙头100外壳103内的流道连通于混水阀102，混水阀102向该进水口114注入水流。第一出水口121通过淋浴管106接通于出水管110，第二出水口122通过软管107连通于花洒109，第三出水口211通过淋浴管107连通于顶喷108。
当进水口114与第一出水口121相连通时，水流依次通过进水口114、第一出水口121而到达出水管110；当进水口114与第二出水口122相连通时，水流依次通过进水口114、第二出水口122和软管107而到达花洒109；当进水口114与第三出水口211相连通时，水流依次通过进水口114、第三出水口211和淋浴管106而到达顶喷108。
在一个示意性实施例中，如图16、17所示，第一密封垫31可以包括第一垫板311和多个第一凸棱317。第一垫板311构造可以为大致的圆形平板。第一垫板311覆盖在隔板13上。第一密封垫31的直径等于第二管段112的内径。第一垫板311的中部贯穿设置有第一装配孔312。在本申请实施例中，实心轴段22的横截面可以为大致的半圆形，第一装配孔312的形状与实心轴段22的横截面的形状相匹配，实心轴段22贯穿该第一装配孔312。第一通孔314设置在第一垫板311上，且位于第一装配孔312的外周。

如图18、19所示，第一转座32包括第一基座323和多个第一凸起部324。第一基座323可以为大致的圆盘结构。第一基座323的中部贯穿设置有第二装配孔321。第二装配孔321的形状与实心轴段22的横截面的形状相匹配。实心轴段22贯穿该第二装配孔321。
第一凸起部324可以弧形的凸台。第一凸起部324设置在第一基座323靠近第一垫板311的一侧。第一凸起部324与第一垫板311相抵。多个第一凸起部324均匀分布在第二装配孔321的周围。第一凸起部324的数量可以是4个。第二通孔322设置在其中一个第一凸起部324上。每相邻的两个第一凸起部324之间具有一个间隙，每个第一凸棱317伸入到一个间隙中。
由于第一凸棱317伸入到相邻两个第一凸起部324之间的间隙中，在转轴2带动第一转座32转动时，第一凸起部324通过推动第一凸棱317转动来带动整个第一密封垫31转动。
在一个示意性实施例中，如图17所示，第一密封垫31还包括第一套筒316。第一套筒316从第一垫板311的第一装配孔312的周边向第一转座32方向延伸。第一套筒316可以是圆筒。第一套筒316套装在实心轴段22上，第一套筒316的内周面紧贴实心轴段22的外周面。第一套筒316加强了第一垫板311与实心轴段22之间密封，使得水流难以通过第一垫板311与实心轴段22之间的间隙。
在一个示意性实施例中，第一密封垫31还包括第一圆筒315。第一圆筒315从第一垫板311的外边缘向第一转座32方向延伸。第一圆筒315与第一套筒316同轴设置。第一圆筒315的外周面抵接于第二管段112的内周面，第一凸起部324朝向第二管段112内周面的侧壁抵接于第一圆筒315的内周面。第一圆筒315加强了第一垫板311与第二管段112之间的密封，使得水流难以通过第一垫板311与第二管段112之间的间隙。
在一个示意性实施例中，第一凸棱317的相对两端分别连接第一套筒316和第一圆筒315。这样连接后，第一凸棱317、第一套筒316和第一圆筒315相当于相互连接的加强筋板，加强了第一密封垫31整体的结构强度，使得第一密封垫31不容易变形。
在一个示意性实施例中，如图22所示，第二密封垫35包括第二垫板351和多个第二凸棱357。第二垫板351构造可以为大致的圆形平板。第二垫板351覆盖在底座12上。第二密封垫35的直径等于第二管段112的内径。第二垫板351的中部贯穿设置有第三装配孔352。在本实施例中，实心轴段22的横截面可以为大致的半圆形，第三装配孔352的形状与实心轴段22的横截面的形状相匹配，实心轴段22贯穿该第三装配孔352。第三通孔354设置在第二垫板351上，且位于第三装配孔352的外周。
第二凸棱357设置在第二垫板351靠近第二转座34的一侧。第二凸棱357可以为条形凸起。第二凸棱357的数量可以是4个。多个第二凸棱357呈辐射状分布在第三装配孔352的周围。
第二转座34包括第二基座343和多个第二凸起部344。第二基座343可以为大致的圆盘结构。第二基座343的中部贯穿设置有第四装配孔341。第四装配孔341的形状与实心轴段22的横截面的形状相匹配。实心轴段22贯穿该第四装配孔341。
第二凸起部344可以为弧形的凸台。第二凸起部344设置在第二基座343靠近第二垫板351的一侧。第二凸起部344与第二垫板351相抵。多个第二凸起部344均匀分布在第四装配孔341的周围。第二凸起部344的数量可以是4个。第四通孔342设置在其中一个第二凸起部344上。每相邻的两个第二凸起部344之间具有一个间隙，每个第二凸棱357伸入到一个间隙中。
由于第二凸棱357伸入到相邻两个第二凸起部344之间的间隙中，在转轴2带动第二转座34转动时，第二凸起部344通过推动第二凸棱357转动来带动整个第二密封垫35转动。
在一个示意性实施例中，如图22所示，第二密封垫35还包括第二套筒356。第二套筒356从第二垫板351的第三装配孔352的周边向第二转座34方向延伸。第二套筒356可以是圆筒。第二套筒356套装在实心轴段22上，第二套筒356的内周面紧贴实心轴段22的外周面。第二套筒356加强了第二垫板351与实心轴段22之间密封，使得水流难以通过第二垫板351与实心轴段22之间的间隙。
在一个示意性实施例中，如图22所示，第二密封垫35还包括第二圆筒 355。第二圆筒355从第二垫板351的外边缘向第二转座34方向延伸。第二圆筒355与第二套筒356同轴设置。第二圆筒355的外周面抵接于第二管段112的内周面，第二凸起部344朝向第二管段112内周面的侧壁抵接于第二圆筒355的内周面。第二圆筒355加强了第二垫板351与第二管段112之间的密封，使得水流难以通过第二垫板351与第二管段112之间的间隙。
在一个示意性实施例中，第二凸棱357的相对两端分别连接第二套筒356和第二圆筒355。这样连接后，第二凸棱357、第二套筒356和第二圆筒355相当于相互连接的加强筋板，加强了第二密封垫35整体的结构强度，使得第二密封垫35不容易变形。
在一个示意性实施例中，如图3所示，阀芯10还包括两个第一密封圈4。第一密封圈4可以是O形密封圈。两个第一密封圈4均套装在空心轴段21上。第一密封圈4的内缘抵接于空心轴段21的外周面，第一密封圈4的外缘抵接于第一管段111的内周面。两个第一密封圈4分布在条槽113的相对两侧。这样就能避免第一管段111中的水从条槽113中漏出。
在一个示意性实施例中，如图4、8所示，空心轴段21上还设置有两个环形凹槽214。环形凹槽214与空心轴段21同轴设置。两个第一密封圈4分别部分嵌入到这两个环形凹槽214内。
第一密封圈4部分嵌入到环形凹槽214内能避免第一密封圈4在空心轴段21的轴向窜动。
在一个示意性实施例中，如图18所示，第一凸起部324的顶端设置安装盲孔325。第一凸起部324的顶面向背离第一垫板311方向凹陷形成该安装盲孔325。安装盲孔325的开口朝向第一垫板311。如图16所示，第一垫板311上还设置有第五通孔313。该第五通孔313与该安装盲孔325相互对齐。第五通孔313的直径与安装盲孔325的直径相同。
如图3、4所示，阀芯10还包括限位销5和第二弹性件6。第二弹性件6设置在安装盲孔325内。第二弹性件6可以是螺旋弹簧。限位销5可以为大致的柱状结构。限位销5的轴线平行于转轴2的轴线。如图20所示，限位销5包括大直径段51和小直径段52。大直径段51和小直径段52同轴设置，大直径段51的一端连接于小直径段52的一端。大直径段51的直径大于小直径 段52的直径。限位销5的小直径段52插入到安装盲孔325中，限位销5的大直径段51穿过第五通孔313而与隔板13相抵。第二弹性件6套在小直径段52上。第二弹性件6的一端抵接于大直径段51朝向小直径段52的一端的端部，第二弹性件6的另一端抵接于安装盲孔325的孔底。大直径段51背离小直径段52的端面为球面，该球面与隔板13相抵。
如图4所示，隔板13朝向限位销5的一面上可以设置有3个凹槽132。3个凹槽132到转轴2的轴线的距离均与限位销5到转轴2的轴线距离相等。
在切换组件3转动到第一密封垫31上的第一通孔314和隔板13上的孔道133对齐的第一位置时，限位销5的大直径段51部分陷入到第一个凹槽132内。在切换组件3转动到第二密封垫35上的第三通孔354和底座12上的第一出水口121对齐的第二位置时，限位销5的大直径段51部分陷入到第二个凹槽132内。在切换组件3转动到第二密封垫35上的第三通孔354和底座12上的第二出水口122对齐的第三位置时，限位销5的大直径段51部分陷入到第三个凹槽132内。这就使得切换组件3旋转到第一位置、第二位置和第三位置中的任意一个位置上时，限位销5都能插入到凹槽132内，使得切换组件3不易再次转动，从而锁定阀芯10。
在限位销5陷入到凹槽132内后，转轴2对第一转座32施加一个较大的转矩，该球面与凹槽132的开口边缘相互挤压而使得凹槽132的开口边缘对限位销5施加一个挤压力，由于限位销5与隔板13相抵的端面为球面，该挤压力具有一个轴向的分力，该分力指向安装盲孔325的孔底。当该分力大于第二弹性件6对限位销5所施加的弹力时，限位销5将第二弹性件6压缩，限位销5最终能脱离凹槽132而解除对阀芯10的锁定。另外，在进行水路切换时启动手感较大，能提升用户体验。
在一个示意性实施例中，如图7所示，底座12上还设置有第二轴孔123，第二轴孔123为盲孔。第二轴孔123设置在底座12朝向隔板13的一端。该第二轴孔123与转轴2同轴设置。转轴2的实心轴段22插入到该第二轴孔123内，并与该第二轴孔123间隙配合。
实心轴段22背离空心轴段21的一端被第二轴孔123约束，使得转轴2在转动时更加平稳。
在一个示意性实施例中，如图9所示，分水阀101还包括手柄9和第三套筒8。第三套筒8可以为圆筒，套装在第一管段111上。第三套筒8能绕第一管段111转动。拨动件7不与空心轴段21连接的一端连接于第三套筒8。拨动件7可以是螺钉，第三套筒8上设置有一个螺孔81，拨动件7一端拧入该螺孔81后，另一端穿过条槽113插入到空心轴段21的盲孔内，实现与空心轴段21的连接。手柄9设置在第三套筒8外，且固定连接于第三套筒8。在本申请实施例中，可以通过推动手柄9的转动来带动第三套筒8以及拨动件7沿条槽113滑动，进而带动转轴2和切换组件3转动，从而实现阀芯10内的水路的切换。第三套筒8覆盖条槽113，使得分水阀101外观更加美观。
