如图9、12所示，转轴2包括空心轴段21和实心轴段22。实心轴段22的外径可以小于空心轴段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内具有一个第二流道211，该第二流道211轴向贯通空心轴段21。该第二流道211可以是与空心轴段21同轴设置。该第二流道211靠近实心轴段22的一端具有一个端口212，该第二流道211背离实心轴段22的一端连通于第一出水口151。
如图9、12所示，空心轴段21位于第一圆柱腔11内，且与第一圆柱腔11同轴设置。空心轴段21上设置有多个传动齿23。多个传动齿23沿周向均匀地分布在空心轴段21的外周壁上。空心轴段21与第一圆柱腔11的侧壁之间可以是间隙配合。空心轴段21在第一圆柱腔11内能绕自身轴线转动。在空心轴段21与第一圆柱腔11的侧壁之间的密封为轴密封。
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132和空心轴段21上的端口212相连通。实心轴段22从第一圆柱腔11穿过隔板13上的第一轴孔131插入到第二圆柱腔12内。实心轴段22与第二圆柱腔12同轴设置。
切换组件3设置在第二圆柱腔12内。如图13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成形连接，并在实心轴段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进行键连接，例如，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。

进水口143位于第一转座32和第二转座34之间，进水口143连通于第一转座32和第二转座34之间形成的腔室。
如图13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132到转轴2轴线的距离，这样，第一通孔314能随第一密封垫31转动到与孔道132相互对齐的位置。
如图16所示，第二密封垫35上设置有第二通孔354。第二通孔354轴向贯穿第二密封垫35。第二通孔354到转轴2轴线的距离、底座16的第二出水口161到转轴2轴线的距离、底座16的第三出水口162到转轴2轴线的距离和底座16的第四出水口163到转轴2轴线的距离均相等，这样，第二通孔354能跟随第二密封垫35转动到分别与第二出水口161、第三出水口162、第四出水口163相互对齐的位置。
如图13所示，第一转座32上设置有第三通孔322。第三通孔322轴向贯穿第一转座32。第一通孔314与第三通孔322相互对齐。

如图11所示，齿圈42为大致的圆筒形。齿圈42的内周壁上设置有多个齿421，多个齿421沿周向均匀布置。齿圈42套在第一管段141上，且与第一管段141同轴设置。齿圈42的内径大于第一管段141的外径。多个行星齿轮41均设置在齿圈42的内侧，且均与多个齿421相啮合。
转动齿圈42，齿圈42带动行星齿轮41转动，行星齿轮41在转动时带动转轴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能切换分水阀芯10中的水路。
如图18、19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132对齐的第一位置时，从进水口143注入的水流能依次通过第三通孔322、第一通孔314、孔道132、环空腔室210、端口212、空心轴段21内的第二流道211而到达第一出水口151。此时，第二密封垫35上的第二通孔354与底座16上的第二出水口161、第三出水口162和第四出水口163相互错开，第二密封垫35封闭第二出水口161、第三出水口162和第四出水口163。
如图20、21所示，在切换组件3转动到第二密封垫35上的第二通孔354和底座16上的第二出水口161对齐的第二位置时，从进水口143注入的水流能依次通过第四通孔342、第二通孔354而到达第二出水口161。此时，第二密封垫35上的第二通孔354分别与底座16上的第三出水口162、第四出水口163相互错开，第二密封垫35封闭第三出水口162和第四出水口163，同时，第一密封垫31上的第一通孔314与隔板13上的孔道132相互错开，第 一密封垫31封闭隔板13的孔道132。
如图22、23所示，在切换组件3转动到第二密封垫35上的第二通孔354和底座16上的第三出水口162对齐的第三位置时，从进水口143注入的水流能依次通过第四通孔342、第二通孔354而到达第三出水口162。此时，第二密封垫35上的第二通孔354分别与底座16上的第二出水口161、第四出水口163相互错开，第二密封垫35封闭第二出水口161、第四出水口163，同时，第一密封垫31上的第一通孔314与隔板13上的孔道132相互错开，第一密封垫31封闭隔板13的孔道132。
如图24、25所示，在切换组件3转动到第二密封垫35上的第二通孔354和底座16上的第四出水口163对齐的第四位置时，从进水口143注入的水流能依次通过第四通孔342、第二通孔354而到达第四出水口163。此时，第二密封垫35上的第二通孔354分别与底座16上的第二出水口161、第三出水口162相互错开，第二密封垫35封闭第二出水口161、第三出水口162，同时，第一密封垫31上的第一通孔314与隔板13上的孔道132相互错开，第一密封垫31封闭隔板13的孔道132。
由此，能通过驱动齿轮组4能将进水口143选择性地仅与第一出水口151、第二出水口161、第三出水口162、第四进水口143中的任意一个相接通。
在本实施例中，分水阀芯10的进水口143连通于混水阀芯86，混水阀芯86向该进水口143注入水流。第一出水口151通过淋浴管92接通于顶喷91，第二出水口161通过第一软管93连通于花洒94，第三出水口162通过第二软管95连通于喷枪96，第四出水口163连通于出水管97。
当进水口143与第一出水口151相连通时，水流依次通过进水口143、第一出水口151和淋浴管92而到达顶喷91；当进水口143与第二出水口161相连通时，水流依次通过进水口143、第二出水口161和第一软管93而到达花洒94；当进水口143与第三出水口162相连通时，水流依次通过进水口143、第三出水口162和第二软管95而到达喷枪96；当进水口143与第四出水口163相连通时，水流依次通过进水口143、第四出水口163而到达出水管97。
在一个示意性实施例中，如图2、3所示，分水阀芯10还包括手柄72和筒体71。筒体71为圆筒，套装在齿圈42上。筒体71与齿圈42同轴设置。 筒体71与齿圈42之间固定连接，筒体71与齿圈42之间可以是花键连接。手柄72设置在筒体71外，且连接于筒体71。
可以通过推动手柄72来带动齿圈42转动，进而带动转轴2和切换组件3转动，从而实现阀芯内的水路的切换。筒体71覆盖第一安装孔144，使得龙头80外观更加美观。
在一个示意性实施例中，如图11所示，齿圈42上齿421的数量大于空心轴段21上传动齿23的数量。
齿圈42通过行星齿轮41带动转轴2转动时，齿圈42转动的角度小于转轴2转动的角度。这样，齿圈42只需要转动较小的角度转轴2就能带动切换组件3快速转动到位。
在一个示意性实施例中，齿圈42上齿421的数量为空心轴段21上传动齿23数量的两倍。
齿圈42通过行星齿轮41带动转轴2转动时，转轴2转动的角度为齿圈42转动的角度的两倍。即，齿圈42转一圈时转轴2转两圈。
在本实施例中，切换组件3从第一位置切换到第二位置需转动90度，从第二位置切换到第三位置需继续转动90度，从第三位置切换到第四位置需继续转动90度。而齿圈42每转动45度，转轴2就能带动切换组件3转动90度，齿圈42只需要在135度的范围内进行转动即可完成切换组件3从第一位置到第四位置的切换。故，手柄72也仅需在0～135度的范围内摆动即可，在将龙头80贴墙安装且分水阀芯10靠近墙面时，手柄72不会与墙面发生干涉。
在一个示意性的实施例中，行星齿轮41均设置有两个，第一安装孔144也设置有两个。两个第一安装孔144分别设置在第一管段141的相对两侧。两个第一安装孔144均与空心轴段21上的传动齿23平齐。两个行星齿轮41分别设置在两个第一安装孔144内，两个行星齿轮41分别位于空心轴段21的相对两侧。
两个行星齿轮41在将齿圈42施加的转矩传递给空心轴段21时，空心轴段21受力平衡，不容易卡死。
在一个示意性实施例中，如图9、10所示，第一管段141的外径小于第二管段142的外径。分水阀芯10还包括压帽43和防磨垫圈44。压帽43构造为圆形的套筒。压帽43套装在第一管段141上。压帽43上设置有设置成与龙头80的外壳85螺纹进行连接的外螺纹。
压帽43的内径可以小于第二管段142的外径。压帽43位于第二管段142与齿圈42之间。防磨垫圈44套装在压帽43上，防磨垫圈44朝向齿圈42的一端抵接于齿圈42。如图10所示，压帽43上还设置有第一限位凸起431，第一限位凸起431从压帽43的外周面径向向外突出。第一限位凸起431设置在防磨垫圈44背离齿圈42的一侧。第一限位凸起431抵接于防磨垫圈44背离齿圈42的一端。这样，防磨垫圈44夹设在第一限位凸起431和齿圈42之间，设置成减小齿圈42与压帽43之间的磨损。
在一个示意性实施例中，如图8-10所示，出水接头15的端盖152上还设置有第二限位凸起155。第二限位凸起155从端盖152的边缘径向向外凸出。第二限位凸起155设置在齿圈42背离防磨垫圈44的一端。第二限位凸起155和防磨垫圈44能防止齿圈42轴向移动，避免齿圈42脱离分水阀芯10。
在一个示意性实施例中，如图13、14所示，第一密封垫31包括第一垫板311和多个第一凸棱317。第一垫板311构造为大致的圆形平板。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142的内径。第一垫板311的中部贯穿设置有第一装配孔312。在本实施例中，实心轴段22的横截面为大致的半圆形，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的外侧。
第一凸棱317设置在第一垫板311靠近第一转座32的一侧。第一凸棱317为条形凸起。第一凸棱317的数量可以是4个。多个第一凸棱317呈辐射状分布在第一装配孔312的周围。
如图13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可以为弧形的凸台。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。第三通孔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10、14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，如图10、14所示，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142的内周面，第一凸起部324朝向第二管段142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142之间的密封，使得水流难以通过第一垫板311与第二管段142之间的间隙。
在一个示意性实施例中，如图14所示，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13、16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可以构造为大致的圆形平板。第二垫板351覆盖在底座16上。第二密封垫35的直径等于第二管段142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。第二通孔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。
如图13、15所示，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22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10、13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10、13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142的内周面，第二凸起部344朝外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142之间的密封，使得水 流难以通过第二垫板351与第二管段142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10所示，分水阀芯10还包括两个密封圈6。密封圈6可以是O形密封圈。两个密封圈6均套装在空心轴段21上。密封圈6的内缘抵接于空心轴段21的外周面，密封圈6的外缘抵接于第一管段141的内周面。两个密封圈6分布在第一安装孔144的相对两侧。这样就能避免第一管段141中的水从第一安装孔144中漏出。
在一个示意性实施例中，空心轴段21上还设置有第一环形凹槽213和第二环形槽214。第一环形凹槽213和第二环形槽214均与空心轴段21同轴设置。两个密封圈6分别部分嵌入到第一环形凹槽213和第二环形槽214内。
两个密封圈6分别部分嵌入到第一环形凹槽213和第二环形槽214内能避免密封圈6在空心轴段21的轴向窜动。
在一个示意性实施例中，如图10、17所示，分水阀芯10还包括碰珠座51、碰珠52和第二弹性件53。碰珠座51呈大致的圆盘形。碰珠座51设置在第二管段142内，并固定在第二管段142上。碰珠座51与第二管段142同轴设置。碰珠座51位于第一转座32和第二转座34之间。碰珠座51与第二管段142之间可以是卡扣连接。碰珠座51的外缘上设置有卡扣511，该卡扣511卡接到进水口143上。
如图17所示，碰珠座51的中部设置有一个第五通孔510。该第五通孔510是通孔。该第五通孔510的直径大于第一弹性件33的外径。第一弹性件33和实心轴段22均贯穿该第五通孔510。碰珠座51朝向第一转座32的端面向内凹陷形成四个限位槽512。四个限位槽512到转轴2的轴线的距离相等。
如图9所示，第一转座32上还设置有安装盲孔325。第一转座32的安装盲孔325位于第一转座32朝向第二转座34的一侧。安装盲孔325的延伸方向平行于第一转座32的轴线。
第二弹性件53设置在安装盲孔325内。第二弹性件53可以是螺旋弹簧。碰珠52为大致的柱状结构。碰珠52的轴线平行于转轴2的轴线。如图17所示，碰珠52包括大直径段522和小直径段523。大直径段522和小直径段523同轴设置，大直径段522的一端连接于小直径段523的一端。大直径段522的直径大于小直径段523的直径。碰珠52的小直径段523插入到安装盲孔325中，碰珠52的大直径段522与碰珠座51相抵。第二弹性件53套在小直径段523上。第二弹性件53的一端抵接于大直径段522朝向小直径段523的一端的端部，第二弹性件53的另一端抵接于安装盲孔325的孔底。大直径段522背离小直径段523的端面为球面，该球面与碰珠座51相抵。
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132对齐的第一位置时，碰珠52的大直径段522部分陷入到第一个限位槽512内。在切换组件3转动到第二密封垫35上的第二通孔354和底座16上的第二出水口161对齐的第二位置时，碰珠52的大直径段522部分陷入到第二个限位槽512内。在切换组件3转动到第二密封垫35上的第二通孔354和底座16上的第三出水口162对齐的第三位置时，碰珠52的大直径段522部分陷入到第三个限位槽512内。在切换组件3转动到第二密封垫35上的第二通孔354和底座16上的第四出水口163对齐的第四位置时，碰珠52的大直径段522部分陷入到第四个限位槽512内。
这就使得切换组件3旋转到第一位置、第二位置、第三位置、第四位置中的任意一个位置上时碰珠52都能插入到限位槽512内，使得切换组件3不易再次转动，从而锁定分水阀芯10。
在碰珠52陷入到限位槽512内后，转轴2对第一转座32施加一个较大的转矩，该球面与限位槽512的开口边缘相互挤压而使得限位槽512的开口边缘对碰珠52施加一个挤压力，由于碰珠52与碰珠座51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53对碰珠52所施加的弹力时，碰珠52将第二弹性件53压缩，碰珠52最终能脱离限位槽512而解除对分水阀芯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10所示，碰珠座51上的卡扣511设置有 两个，两个卡扣511分别设置在碰珠座51的相对两侧。第二管段142上的进水口143也设置有两个，两个进水口143分别设置在第二管段142的相对两侧。两个卡扣511分别卡接在两个进水口143上。
两个对称设置在碰珠座51上的卡扣511分别卡接到两个对称设置在第二管段142上的进水口143上，碰珠座51安装得更加稳固。同时，设置两个进水口143同时进水能增大进水流量。
在一个示意性实施例中，如图17所示，碰珠座51上设置有多个沟道513。沟道513由碰珠座51的外周面向内凹陷形成。多个沟道513均匀的分布在碰珠座51的外缘上。沟道513的延伸方向为碰珠座51的轴向。沟道513贯穿碰珠座51。
水流不仅能沿碰珠座51上的第五通孔510流向第二转座34与碰珠座51之间的空腔中，还能沿这些沟道513流向第二转座34与碰珠座51之间的空腔中，这样就增大了第二出水口161、第三出水口162和第四出水口163的出水流量。
在一个示意性实施例中，如图7所示，底座16上还设置有第二轴孔164，第二轴孔164为盲孔。第二轴孔164设置在底座16朝向隔板13的一端。该第二轴孔164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164内，并与该第二轴孔164间隙配合。
实心轴段22背离空心轴段21的一端被第二轴孔164约束，使得转轴2在转动时更加平稳。
