上述分流阀 7还包括一个用于顶紧上述阀芯主体 24的螺母 31 , 上述螺母 31与上述主体 1螺紋连接。 螺母 31的作用是防止漏水， 密 封性更加好。
上述定阀片 10的第一进水口 12和第二进水口 13对称设置且形 状成喇叭状， 一端是扇形端口 27 , 另一端是第一圆形端口 28。 喇叭 状设计可以加快流量。上述 2个扇形端口 27设置在上述定阀片 10的 内圈。
上述定阀片 10的第一出水口 14和第二出水口 15对称设置且形 状成喇叭状， 一端是圆弧形端口 29, 另一端是第二圆形端口 30。 上 述 2个圆弧形端口 29设置在上述定阀片 10的外圈。
上述 2个第一圆形端口 28和 2个第二圆形端口 30均匀设置在上 述定阀片 10的另一端。
上述恒温阀 6与上述热水入口 2相靠近。 这样设置的好处是： 使 主体 1不会发烫， 防止烫伤。 上述上出水口 4和下出水口 5位于上述 主体 1的中间位置。 这样设置的好处是： 水压更加稳定可靠。
为了防止上述动阀片 9不被上述铜杆 22磨损，在上述铜杆 22和 上述动阀片 9之间设置有一个垫片 37。
上述主体 1内， 由一薄壁 34将第一流道 32和第二流道 33隔开， 上述薄壁 34正对上述分流阀 7。
本水龙头的工作原理是： 控制对动阀片 9的转动， 实现对水龙头 水路的控制， 即控制恒温水水流从上出水口 4出水、 下出水口 5出水 或者关闭水流。 第二手轮 36与上述恒温阀 6连接， 第二手轮 36的转 动可以调节恒温水的温度。
如图 13所示， 当水流处于关闭状态时： 定阀片 10与动阀片 9的 配合关系为： 第一进水口 12、 第一出水口 14及第二出水口 15被动 阀片 9密封遮盖， 第二进水口 13与导通盲孔 21连通， 第五进水口 20没有孔连通。 当然， 动阀片 9再旋转 180° , 也同样是关闭状态。
如图 14所示， 当水流从上出水口 4出水时： 相对于水流处于关 闭状态时， 第一手轮 8逆时针转动 90° , 定阀片 10与动阀片 9的配 合关系为： 第一进水口 12、 导通盲孔 21和第二进水口 13相互连通， 第一出水口 14与第五出水口 20连通， 第二出水口 15被动阀片 9密 封遮盖。 水流如下： 冷水从冷水入口 3流入， 进入第一流道 32 , 再 依次流入第三进水口 16、 第一进水口 12、 导通盲孔 21、 第二进水口 13、 第四进水口 17及第二流道 33 , 流向恒温阀 6; 同时热水从热水 入口 2流入， 进入第三流道 35 , 流向恒温阀 6; 冷、 热水在恒温阀 6 交汇， 形成恒温水； 恒温水流向分流阀 7 , 即恒温水进入第六进水口
25、 第五出水口 20、 第一出水口 14及第三出水口 18, 最终流向上出 水口 4, 从而实现向上出恒温水。
如图 15所示， 当水流从下出水口 5出水时： 相对于水流处于关 闭状态时， 第一手轮 8顺时针转动 90° , 定阀片 10与动阀片 9的配 合关系为： 第一进水口 12、 导通盲孔 21和第二进水口 13相互连通， 第二出水口 15与第五出水口 20连通， 第一出水口 14被动阀片 9密 封遮盖。 水流如下： 冷水从冷水入口 3流入， 进入第一流道 32 , 再 依次流入第三进水口 16、 第一进水口 12、 导通盲孔 21、 第二进水口 13、 第四进水口 17及第二流道 33 , 流向恒温阀 6; 同时热水从热水 入口 2流入， 进入第三流道 35 , 流向恒温阀 6; 冷、 热水在恒温阀 6 交汇， 形成恒温水； 恒温水流向分流阀 7 , 即恒温水进入第七进水口
26、 第五出水口 20、 第二出水口 15及第四出水口 19, 最终流向下出 水口 5 , 从而实现向下出恒温水。
本发明的一种恒温水龙头， 去掉了止回阀这个部件， 内部结构简 单， 控制动阀片的转动， 实现对水龙头水路的控制， 即控制恒温水水 流从上出水口出水、 下出水口出水或者关闭水流； 冷、 热水到恒温阀 出恒温水之前， 冷水须先经过分流阀， 在分流阀关闭出恒温水同时闭 合冷水以有效防止串流， 冷水出入于分流阀左右两侧， 实现分流阀控 制整个水路，可大大简化龙头内部结构，使用寿命和可靠性大大提高， 且不会溢水或者慢漏。
实施例二
如图 16所示， 实施例二与实施例一基本相同， 不同之处在于： 导通盲孔 21的个数为 2个。 2个导通盲孔 21对称设置。
本发明的一种恒温水龙头， 导通盲孔的个数为 2个， 加快冷水的 水流流速， 效率更加高。
综上所述， 上述实施方式并非是本发明的限制性实施方式， 凡本
