本发明所说结构的这种水龙头的出水通道 2, 用于接受并约束微型射流器 5 出流端锥形扩口高速喷射的气水液流, 以定向集束的加速获得更好的气水混合 有利水中曝气增氧效果。 出水通道 2出口端为 了配合可调导流罩 7联接围屏形 成局部制造可控曝气增氧气水幕墙缓冲空间, 其空间大小应与微型射流器 5的 射流孔 29的出水流量成正比关系匹配, 在出 水通道 2出口端数倍扩大出水通道 出口端孔径 r2及延伸扩大容积。 在实际使用中,其出水通道孔径 rl可以在 5— 8 毫米之间与微型射流器 5出流端的锥形扩口对接; 出水通道管壁长度 L在
10— 400毫米之间选择, 可以根据不同制作需求采用分体制作弯曲如鹅颈等适用 形态再对接联接, 可以径向转动出水口角度向上喷洒使用等和满足美观设计的 需求。
本发明所说结构的这种水龙头的可调导流罩 7类似桶形, 其导流罩面 27设 有多环均布排列的出水孔 26, 各孔径在 0. 8— 2毫米之间, 用圆环垫圈 21将其 分隔成圆环内面 22与圆环外面 23各自不同环数排列的不同出水孔数形成不同 的出流水阻。 由导流罩面 27的圆环垫圈 21对应水龙头主体 1出口端小径 18的 圆环型管壁, 通过可调导流罩 7旋紧压迫贴合密封, 使导流罩面 27形成相对高 的出流水阻只有圆环内面 22的出水孔出水 , 可以使水流集流加速; 当旋松状态 时使导流罩面 27的圆环内面 22、 外面 23的出水孔互通, 同时分流出水形成相 对低的出流水阻使水流分流减速。 导流罩面 27外面约呈弧形, 其出水孔 26的 出水孔角度 28在 10度至 45度之间, 可以以较小的导流罩面 27获得所需较大 的喷淋水形面积。
通过流量调节定位螺杆 6无级调节增减流量达到导流罩面 27的出水孔 26 改变流速改变出水形态, 能动态处理好供水压力、 流量与出流水阻关联变化影 响流速、 水形的矛盾, 解决不能动态匹配直接影响出流水形的问题。 如图 2所示, 本发明所说结构的这种水龙头, 为解决进水通道 3的进水压 力使使用者旋动流量调节定位螺杆 6必须克 服反顶水压力造成的操作困难, 在 所说的水龙头主体 1的后端空心内圆管壁 14内, 紧固镶嵌内置螺母 15, 通过相 应减小流量调节定位螺杆 6的螺纹直径、 增 大转动手柄力偶矩可以减少径向转 动操作的磨损及使用者的旋动力量, 提高操作灵活性、 舒适性。 设工艺调节螺 丝孔 17有利装配、 维修。
如图 3所示, 本发明所说结构的这种水龙头, 可以以卧式联接满足面盆及 花洒淋浴卫浴使用。
把本发明所说的这种水龙头的进水通道 3使用外接螺纹联接件 30与进水开 关管座 31接通水源, 水流由进水通道 3 进入水龙头主体 1, 由于中空流量调节 阀 8的后端被流量调节定位螺杆 6轴向相顶锁定后移行程位置, 径向被密封圈 12密封分隔形成由中空流量调节阀 8的大、 小圆柱径差空间及中空流量调节阀 8 的前端锥形头部与微型射流器 5入流端的锥形扩口部分的角度相同, 构成与进 水通道 3具有可移动贴合的锥形环缝隙的动密 封空间, 与被密封圈 12密封分隔 的另侧在用水过程形成水流压力差, 在水流压力作用下自然迫使中空流量调节 阀 8沿轴向后移分离增大锥形环缝隙增大进水通道 3的空间, 使水流由锥形环 缝隙和中空流量调节阀 8的进出水孔 10、 喷孔 9分二路进水汇入微型射流器 5 的射流孔 29。 水流随锥形环缝隙的大、 小变更, 自动平衡二路水流相互交替复 合进入微型射流器 5的射流孔 29, 通过调节锥形环缝隙的大小喷射多种出流水 型 : 如集束喷射、 发散喷射、 雾状喷射等, 中空流量调节阀 8的喷孔 9可以作 水枪的喷嘴直接打开可调导流罩 7使用。 当流量调节定位螺杆 6后移至最大行 程时, 锥形环缝隙的开启至最大, 因进水通道 3的水流压力平衡使中空流量调 节阀 8的进出水孔 10与锥形头部中心喷孔 9二端的水流通道自然断流, 得到由 自来水提供最大静态供水压力使水流进入微型射流器 5的射流孔 29; 当流量调 节定位螺杆 6在调节行程上、 下限的范围内, 得到限流调压无级调节供水输送 流量与输送水压成正比关系的用水特点。 当调节流量调节定位螺杆 6至最小行 程时, 锥形环缝隙被中空流量调节阀 8 的前端锥形头部完全贴合封闭, 使水流 只能经由进出水孔 10通过喷孔 9进水, 此时喷孔 9顺势成为微型射流器 5复合 的小射流孔得到由自来水提供的最大静态供水压力。 当锥形环缝隙未完全闭合 时, 由喷孔 9提供的高速集束射流动能对锥形环缝隙的进水也具有一定的引射 抽液功能, 有助提高微型射流器 5的射流出水 力度, 与可调导流罩 7的低出流 水阻匹配使用符合管嘴出流效应可提高约 30%的使用水量。 本发明所说结构的水 龙头射流孔 29的孔径为 4. 2毫米时, 在标准水压 0. IMPa, 技术上可以达到每分 钟 9升以上的供水量, 根据不同的使用标准可 以下调射流孔 29的孔径来调控水 龙头上限供水量达到每分钟 9升以下, 孔径在 2. 5毫米至 4. 5 毫米之间选取。 当喷孔 9的孔径为 1. 3毫米时, 定孔限定下限用水流量可以控制得到每分钟 1.5 升至 1.8升之间, 孔径在 0. 8毫米至 1. 8毫米之间选用。
当本发明所说结构的水龙头主体 1, 用水过程可以使用流量调节通过进气单 向阀 13与可调导流罩 7的出流组合 , 转换出流水阻改变导流罩内水流的压力, 除取得低水阻出流的优质使用功能的特有效果外, 得到由低水阻出流转换到高 水阻满管流出流完全不同的用水功能效果, 同时具有流量调节阀输送较大供水 压力动能的特点, 通过从技术上匹配保证在高低水压与大小流量用水过程都能 使微型射流器 5获得必要的高速集束射流动 能提供射流孔 29增速降压产生负 压, 在气孔 4经进气单向阀 13抽入空气, 通过出水通道 2形成定向的高速气水 混合液流直接射向可调导流罩 7, 保证使空气与水得到强烈的溅射撞击快速膨胀 曝气迅速增加气水容积的压力, 形成以水阻水的气水幕墙效应达到缓冲减速增 压, 在高速气水混合液流冲击力和曝气压力综合形成大於出流阻力的势能推动 下, 由可调导流罩 7使用相对低的出流水 阻, 使气水液流顺势快速通过导流罩 面 27分流出水, 形成气夹水喷涌似 飞瀑雨点般的飘洒出流特点, 有效解决高速 水流需以低速均匀舒适出流的技术掌控难题。 并通过高速水流溅射的水中曝气 撞击过程产生激活效应释放负离子, 促进提高水体的液含:)氧能力, 促进气体与 液体之间的物质交换排出曝气挥发性物质如余氯。 当可调导流罩 7转换相对高 的出流水阻大流量用水时导致微型射流器 5射流的出流水阻压力高于大气压力 时, 进气单向阀 13会自动闭合阻止水流从进气孔通道 4反向冲出, 实现随机匹 配自动转换开、 闭, 具有流量调节阀输送较大供水压力动能的特点, 具有水枪 出流溅射压力的冲洗力度。 充分发挥出供水、 出水技术匹配实现集水龙头、 花 洒水枪使用功能为一体的整体功能优势互补的效果。
如图 4所示, 本发明所说结构的这种水龙头, 可以把进水开关管座 31与水 管 32立式联接使用。
