该固定部分100的具体结构例如为：包括本体130、面盖组件140、上盖150、固定座160和分水体170。
该本体130分为手持座131和头部座132，该头部座132设出水盖133，该出水盖133设贯穿通孔；该面盖组件140装接在出水盖133处且面盖组件140的出水嘴一一对应穿过贯穿通孔。该分水体170密封固接面盖组件140且形成有上述至少两分水路，不同分水路对应不同出水水花。该分水体170之顶面凸设有环壁171，该固定座160密封固定盖接在环壁171之上，使环壁171内形成有上述的分水腔180，该分水体170之对应环壁171的部分为分水腔底壁，该固定座160之对应环壁171的部分为分水腔顶壁。该固定座160具有一密封固接在环壁171之上的固接部分161及一固接在固接部分161的延伸部分162。该延伸部分162设有进水部分，该进水部分一端接通分水腔，另一端接通供水部分，该进水部分和供水部分也为进水路的部分。该上盖固接本体的头部座132且该面盖组件140、固定座160和分水体170都介于上盖和头部座之间，
为了使切换机构及驱动机构布局更佳合理、紧凑，优选方案中可采用如下结构：
该阀轴220之上端自由密封穿过分水腔顶壁之上，本实施例之中，既，该阀轴220之上端自由密封穿过固定座160之上；该固销222固接在阀轴220之伸出部分且具有伸出阀轴220的两端；该第二翘板430第二端设成拨叉，该拨叉叉接阀轴220且固销之两端撑靠在拨叉之上。

该第二翘板430之第一端凹设有有上下贯穿的第一通槽431，该第一通槽431的槽口处固设有横杆432，该第一翘板420位于第一通槽431内，该第一翘板之第二端顶抵在横杆之上。进一步地，最好：该横杆432之顶面低于第一通槽431之顶端且形成台阶，第一翘板420第二端高度和台阶高度适配；或和;该两第一凸耳163伸入第一通槽内。
该固接部分161之上凸设两第二凸耳164，该第二凸耳164凹设一半圆槽，该上盖150底面凸设两第三凸耳，该第三凸耳凹设一半圆槽，该上盖和固定座固接，该半圆槽适配成圆形槽，该第二翘板枢接该圆形槽。
该手持座131具有一末端管134及一固接在末端管和头部座132之间的U形槽135，该上盖还盖接该U形槽之开口。该滑块410滑动连接在U形槽135之内且位于固定座160之下；该第一翘板420的第一端自安装通槽165伸出，该滑块410前端朝上凸设有顶抵块412，该顶抵块412至少部分伸进安装通槽165内，该顶抵块412顶抵第一翘板420的第一端。该U形槽之槽底设滑孔，该操作钮位于U形槽之外且穿过滑孔固接滑块，以能带动滑块滑动。
该固定座160之进水部分包括一能接通供水部分的进水段166、两分布设在安装通槽两侧的分流段167及一接通两第二进水段166的汇流段，该汇流段接通分水腔。为了方便正常、装配或其它零部件的安装，根据需要，该固定座凹设有水槽，另设盖板169密封固接该水槽的槽口以使水槽形成上述的两分流段167及部分进水段166。
该弹性体300连接在滑块410和固定部分100。具体结构中，该滑块410前端凸设有第一连接耳411，该第一连接耳411设成拨叉结构；该固定座160之安装通槽的下槽口固设一悬板，该悬板末端凸设第二连接耳168，该第二连接耳168设成拨叉结构；另设一连接杆450，该连接杆450头端和尾端都凸设凸环，该连接杆450连接第一连接耳411、第二连接耳168的拨叉内，且头端凸环位于第一连接耳之前，尾端凸环位于第二连接耳之后，该弹性体300为弹簧套接连接杆且顶抵在第二连接耳和尾端凸环之间。
该固定部分100的本体的末端管134内固设有一芯轴190，该芯轴190设供水通道及贯穿芯轴190上下的止水通道191，该止水通道191滑动连接有止水机构；该滑块410能相对固定部分100在切换位置和中间位置之间、中间位置和止水位置之间滑动，该中间位置位于切换位置和止水位置之间；通过滑块410由中间位置滑动至止水位置能带动止水机构滑动实现止水，该滑块410由止水位置滑回中间位置，在水压作用下止水机构复位。具体结构如下描述：
该芯轴190设有一通至止水通道191内的进水孔192及一由止水通道191内通至止水通道外的出水孔193，该进水孔、止水通道和出水孔构成供水通道的部分，出水孔接通分水腔，或者说，通过进水通道接通分水腔，具体来说，出水孔接通进水通道的进水段166。
该止水通道191具有小截面面积段194及大截面面积段195，该进水孔设在大截面面积段，该出水孔设在小截面面积段；小截面面积段194及大截面面积段195上下布置。
该止水机构包括第一止水座196和第二止水座197，该第一止水座和第二止水座固接在一起，该第一止水座适配大截面面积段，该第二止水座适配小截面面积段，该第二止水座位于出水孔之上，通过第一止水座密封进水孔实现止水。第一止水座196和第二止水座197之间的连接处和止水通道之间形成过水间隙，使水流从进水孔进入后，能经过水间隙流至出水孔，再由出水孔流出。
该第一止水座底面凹设连接槽，该连接槽内放置有滚球198，该滚球至少部分伸出连接槽槽口，既，槽深度小于滚球直径；该滑块410设有导向斜面413及分别连接导向斜面413两侧的第一平面和第二平面，第一平面、导向斜面413和第二平面前后布置，该滚球滚动连接在导向斜面413、第一平面、第二平面。
为了进一步说明本实施例，下面简单介绍切换止水原理：
初始时：分水盘密封第一分水孔，此时第二分水孔接通分水腔，第二分水路出水；
滑块向前滑动以从中间位置滑动到切换位置，滑块顶抵第一翘板第一端带动第一翘板摆动，第一翘板第二端顶抵第二翘板第一端带动第二翘板摆动，第二翘板第二端拨动阀轴向上滑动，通过第一传动机构使分水盘转动1/2恒定角度，用户释放滑块，滑块在弹性体弹力作用下由切换位置复位至中间位置，阀轴在弹簧作用下复位，分水盘再转动1/2恒定角度，此时切换完成，分水盘介于两分水孔之间，两分水孔都接通分水腔，出混合水；滑块向前滑动并复位，以使分水盘再转动一恒定角度，以密封第二分水孔，此时第一分水孔接通分水腔，第一分水路出水。本实施例之中以两分水路为例，但并不以此进行限制，根据需要，三个或四个分水路都使用本实施例。
滑块向后滑动以从中间位置滑动到止水位置，滚球配合位置由第二平面经导向斜面后变至第一平面，在导向斜面配合过程中，滚球向上活动，顶抵止水机构也向上滑动，使第一止水座密封进水孔，实现止水。当滑块由止水位置滑回中间位置时，由于第一止水座所受水压面积S1大于第二止水座所受水压面积S2，因此止水机构在水力作用下滑动复位实现通水。
以上所述，仅为本发明较佳实施例而已，故不能依此限定本发明实施的范围，即依本发明专利范围及说明书内容所作的等效变化与修饰，皆应仍属本发明涵盖的范围内。
