随着生活水平的提高，人们对供水阀门的要求也越来越高，例如在淋浴设备中，不仅要求能控制水温、流速，还要求能切换不同的喷洒方式，这一功能通常需要分水器来实现。分水器是专门用于连接各路供水管的配水装置，目前，分水器的使用广泛，种类繁多，市场上现有分水器切换控制技术主要有拉杆式结构、横拨式结构及转动式结构，其基本原理是通过在阀体上开设四个或两个进水口，再配合陶瓷动片和陶瓷定片之间的旋转90°或180°来达到分水的目的。现有的分水器结构比较复杂，涉及到的零部件繁多，故障率高，密封性能和使用寿命欠佳。
我国专利(公告号：CN201507690U；公告日：2010-06-16)公开了一种改进型分水阀，包括卡簧、阀体、密封圈、润滑垫片、阀杆、陶瓷动片、陶瓷定片及底部垫圈，卡簧卡在阀杆上置于阀体顶部，阀杆和阀体之间设有阀体内密封圈；底部垫圈设在阀体底部，往上依次为陶瓷定片、陶瓷动片、动片密封圈、润滑垫片，陶瓷动片固定在阀杆上，阀体外部和水管接触的部位设有顶部密封圈和外部密封圈，阀体侧面设有开口，开口分两排双开口设置，靠近阀体顶部的为进水口，靠近阀体底部的为侧出水口，陶瓷定片对准底部垫圈中心孔的为正出水口；陶瓷定片的侧出水孔正向对准阀体的侧出水口，陶瓷动片叠加在陶瓷定片的上方，陶瓷动片的旋转角度为90°，陶瓷动片转动90°时可以使水流经陶瓷动片的导流孔流向侧出水口或正出水口。

如图1和图2所示，本分水器包括阀体1和阀杆2，阀体1具有沿轴向贯穿的通孔11，阀杆2的下端可转动插设在阀体1的通孔11内，阀杆2的上端向上伸出阀体1的上端之外，阀体1的下端端面具有出水口一12，阀体1的外周面上分别开设有出水口二13和进水口14，进水口14位于出水口一12与出水口二13之间，阀体1的通孔11内位于进水口14与出水口一12之间设有封堵圆盘3，封堵圆盘3的外周面与通孔11的内壁密封连接且封堵圆盘3上开设有上下贯穿的过水孔一31；封堵圆盘3上表面贴靠设置转动盘4且转动盘4能够转动后打开或封闭过水孔一31；阀杆2的下端与转动盘4相连接且能够带动转动盘4旋转；阀杆2的下端侧部具有转动时能够封堵或打开出水口二13的封堵部21。具体来说，阀杆2的上端具有连接部22，连接部22的周面上具有直齿22a，阀杆2的中部外周面上具有多个环形凹槽一23，环形凹槽一23内嵌设有密封圈一5，阀杆2的下端呈筒状或圆柱状且封堵部21为阀杆2下端侧壁的一部分，阀杆2下端的外周面上开设有与出水口二13相对应的过水孔二24；转动盘4的上表面具有卡槽41，阀杆2的下端具有能够插设在卡槽41内的卡接块25；卡槽41和卡接块25的数量均为两个且一一对应设置，通过卡接块25与卡槽41的配合实现阀杆2带动转动盘4旋转；过水孔一31的横截面呈扇形，过水孔一31的数量为两个且两个过 水孔一31以封堵圆盘3的中点呈中心对称分布；转动盘4的两侧具有内凹的过水凹槽42，过水凹槽42的形状及大小与过水孔一31一一对应设置；进水口14具有多个且对称分布在阀体1两侧，出水口二13也具有多个且对称分布在阀体1两侧，当过水凹槽42与过水孔一31相连通时，封堵部21封堵出水口二13，当转动盘4封堵过水孔一31时，过水孔二24与出水口二13相连通。
如图2所示，阀体1的下端具有外螺纹15，阀体1的上端面上具有环形凹槽二16，环形凹槽二16内嵌设有密封圈二7，阀体1的外周面上位于进水口14上下两侧分别具有环形凹槽三17，环形凹槽三17内嵌设有密封圈三8；阀体1的内壁上具有轴向的安装槽，封堵圆盘3的外周面上具有卡接在安装槽内的安装凸起32。进一步的，安装凸起32的数量为两个，对称设置在封堵圆盘3的两侧，安装槽的数量也为两个且与安装凸起32一一对应设置，通过安装凸起32与安装槽的配合限位，保持封堵圆盘3的周向稳固。
本实施例中封堵圆盘3和转动盘4均为陶瓷制成且封堵圆盘3的上表面与转动盘4的下表面相贴靠；封堵部21的外周面上设有橡胶制成的密封片6；进水口14和出水口二13的投影呈矩形，进水口14和出水口二13的长度方向沿阀体1的周向方向设置。
分水器分别连接进水管和两个出水管，进水管与进水口14相连通，两个出水管分别与出水口一12和出水口二13相连通，进水管和两个出水管与本分水器的连接是现有技术，在此不再赘述。本分水器在使用时，阀杆2上端的连接部22连接拧动把手，阀杆2的外周面与阀体1的内壁之间保持密封，防止泄漏，阀杆2转动时分别是封堵部21封堵在出水口二13处或者过水孔二24与出水口二13相导通。通过拧动把手带动阀杆2旋转90°，阀杆2带动封堵部21以及转动盘4转动，当凹槽与过水孔一31相连通时，封堵部21封堵出水口二13，实现出水口一12的出水； 当转动盘4封堵过水孔一31时，过水孔二24与出水口二13相连通，实现出水口二13的出水。
本实施例中的分水器为转动式，在转动阀杆2时受到的周向阻力小，比较省力；通过对称设置过水孔一31、过水孔二24以及出水孔二，只需要旋转90°即可实现出水口的切换，操作行程小，而且流量大，能达到20L/min以上。另外本技术方案中封堵圆盘3和转动盘4采用陶瓷密封，阀杆2在出水口二13处采用橡胶侧面密封，旋转阀杆2时手感轻，密封效果好，使用寿命长。
本文中所描述的具体实施例仅仅是对本发明精神作举例说明。本发明所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本发明的精神或者超越所附权利要求书所定义的范围。
