具体实施方式
[38] 下面结合附图和实施例对本发明进一步说明。
[39] 如图 1〜图 8所示, 本发明的节水防堵防溅瀑布头芯, 包括壳体 4以及位于壳体 4 内的水流疏导口 2, 在水流疏导口 2下方设置有形状、 大小与水流疏导口 2相适配 的档块 3, 档块 3的上表面与水流疏导口 2的出口之间具有间距。 工作吋, 打开水 龙头开关, 水流经疏导孔口 2整束下泄, 此间受水流疏导口 2下方的档块 3的档水 面 (其上表面) 均匀阻挠, 水便会自然向档块 3外周围溢流
, 形成由小而大的薄薄的中空瀑布水帘 11, 又因水表面的张力作用, 形成的中 空瀑布水帘 11又逐渐聚合下泻, 相当于将传统出水口网嘴起泡器微小的气泡扩 充数万倍, 呈现出一个倒水滴状的中空瀑布水罩或类似鹅蛋形的中空瀑布形大 水泡。 靓丽的同吋给人们一种水流量挺大的感觉, 满足使用者的心理需求, 科 学的节约水资源。 再有, 由于档块 3的上表面对水流的阻档缓冲作用, 造成了水 流的部分能量损失, 从而在形成中空瀑布水帘 11下泄吋其能量较小, 使得冲击 力小, 也就使得用水自然柔和, 防止水流飞溅。 另外, 在设置该档块 3后, 则不 需要在水龙头的出水口处设置很多细孔, 仍然能达到防止水流飞溅的目的, 因 此, 可将水流疏导口 2设置为较大的通道, 可防止造成水流中的杂质将水流疏导 口 2堵塞。 在该实施方式中, 档块 3与水流疏导口 2形状、 大小相适配的形式, 可 以是将档块 3的面积设置为略大于、 等于或略小于水流疏导口 2的面积, 以利于 中空瀑布水帘 11的形成; 而水流疏导口 2可设置为圆形、 矩形甚至是不规则的形 状, 而档块 3的形状应对应于水流疏导口 2的形状。
[40] 在上述实施方式中, 可在水龙头的管体外固定设置支架, 并使该支架延伸至水 流疏导口 2下方, 将档块 3连接在水流疏导口 2正下方的支架上即可, 作为优选方 式, 档块 3与壳体 4之间设置有连接结构, 档块 3通过连接结构连接到壳体 4上。 如可釆多根细小的筋杆形成倒伞状, 将该倒伞状的结构一端连接壳体 4, 一端连 接档块 3, 但该方式中, 当水流从水流疏导口 2出来后, 多根细小的筋杆会对水 流造成干涉, 不利于中空瀑布水帘 11的形成, 作为优选实施方式, 所述连接结 构包括固定设置在档块 3上表面的支撑杆 14以及设置在支撑杆 14上并具有通孔 15 的导流支架 5, 支撑杆 14穿过水流疏导口 2, 导流支架 5位于水流疏导口 2上方。 则水流从水流疏导口 2出来后, 顺着支撑杆 14外表下泄到档块 3的上表面处, 没 有任何阻档, 利于中空瀑布水帘 11的形成, 更好防止水流飞溅。
[41] 为了对水龙头水管内出来的水流进行调整, 所述导流支架 5呈凹形, 其凹形部 位形成水流均分室 12, 通孔 15设置在水流均分室 12的侧壁。 则从水龙头水管内 出来后的水流首先进入到水流均分室 12内, 然后再从水流均分室 12的侧壁上的 通孔 15进入到导流支架 5与水流疏导口 2之间的水室内, 再从水流疏导口 2流出。 通过该水流均分室 12的设置, 可将错综复杂的水流进行整流, 利于形成中空瀑 布水帘 11。 当然, 为达到更好的整流效果, 在水流均分室 12的顶部固定设置有 整流盖 9, 在整流盖 9的中部设置有整流通孔 6。 则水龙头水管内出来后的水首先 经整流通孔 6再进入到水流均分室 12内, 可更好地提高整流效果, 防止某些水龙 头出水口角度的不同或构造式样另类而造成对壳体 4内壁的单边冲击, 影响中空 瀑布水帘 11的形态。 该实施方式结构如图 2所示。
[42] 在以上的实施方式中, 可将支撑杆 14直接卡接在导流支架 5上 (如图 1) ; 或将 支撑杆 14与导流支架 5釆用一体成型的结构, 支撑杆 14与导流支架 5—体成型吋 , 需将档块 3的面积设置为略小于水流疏导口 2的面积, 这样才能将档块 3从水流 疏导口 2的上方穿入至下方。 为方便调节中空瀑布水帘 11的大小, 作为优选方式 , 如图 4所示, 支撑杆 14螺纹连接到导流支架 5上, 支撑杆 14的轴心线与整流通 孔 6轴心线重合。 则通过在导流支架 5内旋进或旋出支撑杆 14吋, 也就调整了水 流疏导口 2与档块 3之间的匹配距离, 从而改变中空瀑布水帘 11形态及大小。 另 外通过旋进或旋出支撑杆 14, 可对水龙头内部的水流大小进行调节, 达到节约 水资源的目的。 但是, 当水流疏导口 2与档块 3之间的距离合适吋, 为了便于调 节水流量, 显然就不能通过旋动支撑杆 14来调节水流量, 这吋, 在支撑杆 14与 档块 3内设置有螺纹通孔, 在该螺纹通孔内设置有螺钉 16, 螺钉 16的轴心线与整 流通孔 6轴心线重合, 可方便在出水口的外部调节流量, 省去了进水调节的三角 阀, 适应普通水龙头配置, 实现水资源的合理利用。
[43] 在上述实施方式中, 为了得到恒定的出水量, 所述整流盖 9釆用柔性材料制作 , 并在导流支架 5与整流盖 9之间设置有弹簧 18。 其结构如图 7所示, 当水压较高 吋, 所述柔性的整流盖 9克服弹簧 18的弹性力而往下偏, 即缩小了整流通孔 6与 螺钉 16顶端之间的间隙, 也就相应地限制了出水流量; 反之, 水压低吋, 借助 弹簧 18释放的张力, 整流通孔 6与螺钉 16顶端之间的间隙增大, 适实的增加了出 水量。 再有, 作为补偿出水流量还可以在柔性的整流盖 9上穿刺适量的针孔。 由 于柔性的整流盖 9可据水压变化而使整流通孔 6与螺钉 16顶端之间的间隙发生变 化, 从而自动调节水压波动吋的出水流量, 根据各楼层不同的水压, 一次性的 配合调整螺钉 16, 以保持中空瀑布水帘 11形态更稳定。 当然, 相同原理, 也可 以将整流盖 9釆用弹性元件制作。 即使柔性的整流盖 9替换为具有弹性的整流盖 9 , 也可起到相同的作用。 比如: 整流盖 9釆用不锈钢弹片、 塑料弹片等制作, 可 免设弹簧 18。
[44] 为使本发明的中空瀑布水帘 11的出水方式运用到公开号为 CN1598380A的无活 塞延吋可曲阀芯中, 导流支架 5上设置有泄压室 23, 泄压室 23顶部的导流支架 5 上设置有泄压通道接口 21, 泄压室 23底部的导流支架 5上设置有泄压出水口 24; 支撑杆 14的顶部设置有覆盖泄压出水口 24的密封档板 17, 在密封档板 17的上表 面与导流支架 5之间设置有回位弹簧 19。 其结构如图 8所示, 在本实施方式中, 泄压通道接口 21与公开号为 CN1598380A中的阀壳盖水室腔相通, 而导流支架 5 上的通孔 15与阀壳座矩形水槽相通。 则需要出水吋, 使密封档板 17与泄压出水 口 24形成一定间隙, 密封档板 17克服回位弹簧 19的弹力使水从导流支架 5上的泄 压出水口 24下泄, 而顶起后, 密封档板 17、 支撑杆 14以及档块 3在自身重力以及 回位弹簧 19的作用下回位, 将导流支架 5上的泄压出水口 24自动关闭, 完成泄压 过程。 此吋, 水从导流支架 5上的通孔 15流出, 经水流疏导口 2在档块 3处形成中 空瀑布水帘 11。 而通过在档块 3下端固定设置有下悬式触杆 20, 可便于用手顶动 或摆动下悬式触杆 20并将密封档板 17顶起; 而在密封档板 17下方的导流支架 5上 固定设置有密封圏 22, 可提高密封档板 17与泄压出水口 24之间的密封性。
[45] 为增加中空瀑布水帘 11的美感, 如图 3所示, 在档块 3与支撑杆 14内设置有至少 一个针孔 8。 则在形成中空瀑布水帘 11的同吋, 还有一束或多束水流从中空瀑布 水帘 11的中心处下泄, 可增加出水的美观性, 同吋补偿了中空型水罩瀑布中心 部位无水流的缺失, 更实用并提高了生活质量。 在设置该针孔后, 由于其直径 较小, 为避免其堵塞, 在导流支架 5上设置有覆盖针孔 8顶部的滤网 7, 或釆用穿 透针孔 8的颤针。 而为了更好形成水流的缓流, 在导流支架 5与水流疏导口 2之间 设置有滤网 7。 该滤网 7除了能对水流进一步产生缓流以外, 还能疏导水中的杂 质, 滤、 疏结合, 预防杂质的集聚, 更利于中空瀑布水帘 11的形成与稳定。 本 实施方式尚可根据中空瀑布水帘 11的成形原理, 在档块 3的针孔 8下方再设置一 套小型档块结构。 当然, 需扩大针孔 8的孔径, 形成双层以上的多重中空瀑布水 帘 11, 即中空瀑布内又套小型的中空瀑布, 别具一格。 可供景观造形设置。
[46] 为更好提高美观性, 位于支撑杆 14内的针孔 8的直径大于位于档块 3内的针孔 8 的直径, 在大直径段的针孔 8内设置有发光装置 10。 该发光装置 10可釆用发光材 料或发光灯管制作, 如红色光与绿色光一体的二极管, 导线则从针孔 8上端的空 心柱穿过分别联锁相应电源, 比如: 自来水自发电小装置或微动开关。 届吋, 开启热水中空瀑布水帘 11呈红色瀑布, 用凉水吋则呈绿色光亮, 流动的水帘, 使得光谱色彩随之变化多姿, 丰富生活质量。
[47] 水流疏导口 2可以直接为现有水龙头的水流通道, 水从水龙头的出口下泄到档 块 3的上表面处形成中空瀑布水帘 11, 但其出水面积较大, 不利于水资源的节约 , 作为优选方式, 在壳体 4下部的出口处设置有平台圏 13, 水流疏导口 2设置在 平台圏 13上。 较直接将现有水龙头的水流通道作为水流疏导口 2的形式, 显然可 节约水资源的利用。 该水流疏导口 2可设置在平台圏 13的任意位置, 作为优选方 式, 水流疏导口 2设置在平台圏 13的中部, 可利于各个部件的设置。
[48] 作为平台圏 13的一种优选设置方式, 在壳体 4的内壁固定连接有衬套 1, 平台圏 13为衬套 1的底部。 此吋, 衬套 1的顶部与壳体 4的内壁之间形成台阶, 可将导流 支架 5设置在衬套 1的顶部, 导流支架 5可焊接于该台阶处, 或直接平放于该台阶 处。 。 该方式利于各个部件的拆卸更换。 该结构如图 1、 图 2、 图 3与图 5所示。
[49] 作为平台圏 13的另一种优选设置方式, 所述平台圏 13与壳体 4为一体结构。 即 将平台圏 13与壳体 4在成型吋一体成型, 甚至同吋成型出水流疏导口 2, 或现将 平台圏 13与壳体 4成型出, 然后在平台圏 13上钻出水流疏导口 2, 该方式的特点 是可减少装配环节。 该结构如图 4、 图 6、 图 7与图 8所示。 而在平台圏 13与壳体 4 为一体成型后, 为便于导流支架 5的设置, 在壳体 4上部内壁上设置有台阶, 导 流支架 5支撑在该台阶处, 可将导流支架 5焊接于该台阶处, 或直接平放于该台 阶处。
[50] 为防止 "好奇者"随意拆卸本发明的节水防堵防溅瀑布头芯, 所述壳体 4的外表 面为平滑表面。 比如可将壳体 4制作为中空的圆锥台形状, 如图 5 ; 或将壳体 4的 外表面中部向内凹陷, 如图 6所示, 甚至可将该壳体 4制作为中空的椭圆体以及 现有技术的防拆卸表面。 由于现有的起泡器头芯结构在外表面基本都有用于使 扳手着力的平台或对称缺口台阶。 本发明将壳体 4的外表面免设缺口更显美观。 而装配的着力点是在平台圏 13下方的壳体 4内壁上设置的单向锁紧结构 25。 如可 在平台圏 13下方的壳体 4内壁上设置超越离合器、 单向轴承等结构, 而为使结构 简单, 最好将单向锁紧结构 25设置为下表面具有锯齿形结构的多个凸块或绕壳 体 4内壁设置为整圏结构 (此吋, 锯齿形结构的多个凸块或整圏结构就相当于棘 轮结构, 实现单向转动) , 其结构如图 6中所示, 装配吋应用类似尖嘴钳或专用 的工具拧紧即可。 因为该单向锁紧结构 25只能往一个方向旋转, 就形成了装配 吋能将本发明的节水防堵防溅瀑布头芯拧紧在水龙头出口处, 但拆卸吋却不能 有效将其拆下, 可防止其损坏, 提高使用寿命。 另外, 在装配吋, 为进一步防 止拆卸, 也可将壳体 4焊接、 粘结或压接到水龙头出水口上。
[51] 作为另外的优选设置方式, 可将本瀑布头芯与水龙头悬臂, 设置为一体结构, 即龙头悬臂前下端开深孔将整个瀑布头芯植入, 构成隐形嘴口的水龙头。 装配 吋将本发明中的衬套 1、 档块 3、 支撑杆 14以及导流支架 5等组合为瀑布头芯, 直 接压入或旋入龙头悬臂预留的深孔之中, 由于使用过程无需拆卸清洗, 它与水 龙头外壳体属一次性装配的终身元件, 可增加技术壁垒, 对预防他人仿冒更为 有利, 且可减少装配环节和成本, 由于外表无拆卸着力点,防拆卸防盗效果更好 , 助于品牌的提升。 同吋, 瀑布头芯隐藏于水龙头悬臂设置为一体结构, 也消 除了表面结合痕迹, 可提高外表的美观性。
[52] 另外, 本发明还可以置换匹配部分淋浴花洒喷头中心的起泡器, 使用吋除了呈 中空瀑布水帘 11的新鲜感外, 仅需调节进水阀加大一些流量, 中空瀑布水帘 11 便如同孔雀开屏似的呈伞状, 模似天然的雨水珠, 让沐浴回归大自然。
[53] 需要指出: 上面所述仅是本发明的优选实施方式。 由于对相同技术领域的普通 技术人员来说是很容易在此基础上进行若干修改和改动。 因此, 本说明书并非 是要将本发明局限在所述和所示的具体结构和适用范围内, 故凡是所有可能被 禾 1J用的相应修改以及等同物, 均属于本发明所申请的专利范围。
