Description

自动节水龙头 技术领域
本发明涉及一种节水龙头,特别涉及一种卫生间面盆用自动 节水龙头。 背景技术
在现有技术中,卫生间面盆用洗脸、洗手水龙头由水龙头壳 体、 进水口、 控水阀、 控水阀把手、 水龙头出水口构成, 水龙头 把手装于水龙头上方位置,用水时, 用手调控控水阀把手控制水 量大小、 水温和关闭, 一般情况下洗脸时, 用手将水龙头把手调 到适当位置,水龙头下方的出水口向下流出调好的水流, 然后用 双手捧水洗脸, 洗完后又在出水口下捧水再洗, 由此反复, 一直 至脸洗干净才关闭龙头。但在每次用双手捧水洗脸时水流白白流 走, 造成浪费。
目前解决这一问题的技术方案主要是用一种感应式出水的 水龙头, 即在水龙头出水口附近设置传感器, 以探测用手接近出 水口准备取水信号,并将探测结果传送至控制电器,经电磁阀控 制水龙头的关闭, 但由于结构复杂、 成本高、 可靠性差、 易出故 障而不能大量应用于家庭。 发明内容 1
确 认 本 本发明的目的是提供一种结构巧妙简单、 易于加工制造、成 本低、使用方便的自动节水龙头,用双手捧水的动作即可自动开 启水龙头, 手离开水龙头出水口即可自动关闭水龙头。
本发明提供的技术方案是: 一种自动节水龙头, 包括水龙头 壳体、 控水阀、 控水阀把手、 水龙头进水口、 水龙头出水口, 自 动节水龙头控水阀和水龙头出水口之间装有节水阀, 节水阀按钮 装于水龙头出水口下方位置,节水阀由节水阀自锁杆、 节水阀自 锁杆固定滑套、不锈钢弹簧、水龙头内隔断、节水阀锥形出水口、 封水橡胶圏、 节水阀按钮构成, 节水阀自锁杆上端正面有自锁定 位单向循环滑槽, 节水阀自锁杆上端装于节水阀自锁杆固定滑套 内, 弹性桂钩一端惯穿于节水阀自锁杆固定滑套上的弹性挂钩过 孔, 另一端靠其自身弹性扣压于自锁定位单向循环滑槽的滑槽 内, 节水阀自锁杆固定滑 ^ϋ端边沿开有凹槽, 凹槽内装有固定 用橡胶圏, 节水阀自锁杆固定滑套与节水阀自锁杆弹簧顶板之间 装有不锈钢弹簧, 开于水龙头内隔断上的节水阀锥形出水口的下 端开口直径在 6-7mm之间,封水橡胶圏下端的节水阀自锁杆收缩 部直径为 3. 5醒, 节水阀自锁杆上端正面正中位置开有节水阀自 锁杆 U形槽。
本发明与已有技术相比有以下优点: 结构巧妙简单、 易于加 工制造、 成本低、 安全可靠、 使用方便、 用人们习惯的双手捧水 姿势即可实现水流的自动开闭, 以实现节水的目的,控制节水阀 的自锁装置还可将自动节水龙头方便地转换为普通龙头。 附图说明

下面结合附图对本发明作进一步描述:
图 1是本发明第一种实施例的结构示意图; 图中, 自动节水 龙头包括水龙头壳体 23、 控水阀 2、 控水阀把手 1、 水龙头进水 口 5、 水龙头出水口 12, 节水阀 18装于控水阀 2和水龙头出水 口 12之间的位置,节水阀按钮 9装于水龙头出水口 12下方的节 水阀自锁杆 8下部, 节水阀 18由节水阀自锁杆 8、 节水阀自锁 杆固定滑套 16、 不锈钢弹簧 20、 水龙头内隔断 11、 节水阀锥形 出水口 10、 封水橡胶圏 13、 节水阀按钮 9构成, 节水阀自锁杆 8上端正面有自锁定位单向循环滑槽 22、节水阀自锁杆 8上端装 于节水阀自锁杆固定滑套 16内,弹性挂钩 21—端惯穿于节水阀 自锁杆固定滑套 16上的弹性挂钩过孔 19 , 另一端靠其自身弹性 扣压于自锁定位单向循环滑槽 22的滑槽内, 节水阀自锁杆固定 滑套 16上端边沿开有凹槽, 凹槽内装有固定用橡胶圏 17, 节水 阀自锁杆固定滑套 16与节水阀自锁杆弹簧顶板 14之间装有不锈 钢弹簧 20, 开于水龙头内隔断 11上的节水阀锥形出水口 10的 下端开口直径在 6-7mm之间, 封水橡胶圏 13下端的节水阀自锁 杆收缩部 6直径为 3. 5腿, 节水阀自锁杆 8上端正面正中位置开 有节水阀自锁杆 U形槽 15。
经实验证明, 为解决水压大时手指上压节水阀按钮 9用力过 大问题, 开于水龙头内隔断 11上的节水阀锥形出水口 10的下端 开口直径最优选择在 6-7匪之间, 并将封水橡胶圏 13下端的节 水阀自锁杆收缩部 6直径缩为 3. 5mm以利水流通过,如开于水龙 头内隔断 11 上的节水阀锥形出水口 10 的下端开口直径增大一 倍, 则压力将增加四倍, 节水阀自锁杆固定滑套 16上端边沿开 有凹槽, 凹槽内装有固定用橡胶圏 17, 固定用橡胶圏 17在节水 阀 18壳体内壁与节水阀自锁杆固定滑套 16起固定作用, 防止节 水阀自锁杆固定滑套 16在节水阀 18壳体内滑动, 节水阀自锁杆 8上部可在节水阀自锁杆固定滑套 16内上下滑动,节水阀自锁杆 8下部穿过节水阀自锁杆轴套 7与节水阀按钮 9连接, 节水阀自 锁杆 8向上运动时, 为避开弹性挂钩 21—端惯穿于节水阀自锁 杆固定滑套 16上的弹性挂钩过孔 19, 节水阀自锁杆 8上端正面 正中位置开有节水阀自锁杆 U形槽 15。
使用时, 调控控水阀把手 1的位置, 使控水阀 2开启, 冷热 水分别由左右两边的两个水龙头进水口 5、控水阔进水口 4经控 水阀 2、 控水阀出水口 3进入水龙头内水龙头内隔断 11上方, 当洗脸的手不触碰节水阀按钮 9时, 不锈钢弹簧 20经节水阀自 锁杆弹簧顶板 14将节水阀自锁杆 8向下压, 装于节水阀自锁杆 8上的封水橡胶圏 13向下将节水阀锥形出水口 10封闭, 水龙头 出水口 12无水流出, 洗脸时将双手作捧水状, 其手指向上顶压 节水阀按钮 9时, 不锈钢弹簧 20被压缩, 节水阀自锁杆 8向上 带动封水橡胶圏 13向上离开节水阀锥形出水口 10, 同时, 自锁 定位单向循环滑槽 22上移,滑槽内的弹性挂钩 21—端在滑槽内 随节水阀自锁杆 8的向上运动而滑向自锁定位单向循环滑槽 22 右边底部, 然后手指离开节水阀按钮 9, 在不锈钢弹簧 20的作 用下, 节水阀自锁杆 8向下运动, 滑槽内的弹性桂钩 21—端落 在自锁定位单向循环滑槽 22的中部端点被钩住, 水由水龙头内 隔断 11上方节水阀锥形出水口 10流入水龙头内隔断 11下方经 水龙头出水口 12流出至接于水龙头下方准备捧水的双手上, 接 满水后双手离开水龙头出水口 12下方前, 使手指再向上顶压节 水阀按钮 9 , 节水阀自锁杆 8向上运动使自锁定位单向循环滑 槽 22上移,滑槽内的弹性挂钩 21—端在滑槽内随节水阀自锁杆 8的向上运动而滑向自锁定位单向循环滑槽 22左边底部, 然后 手指离开节水阀按钮 9, 在不锈钢弹簧 20的作用下, 节水阀自 锁杆 8向下运动, 滑槽内的弹性挂钩 21—端顺滑槽落在自锁定 位单向循环滑槽 22 的右边上端, 同时被压缩的不锈钢弹簧 20 经节水阀自锁杆弹簧顶板 14将节水阀自锁杆 8向下压, 封水橡 胶圏 13向下将节水阀锥形出水口 10封住, 水龙头出水口 12水 即被关闭, 当不使用节水阀功能时, 只需用手指将节水阀按钮 9 向上顶到底再离开,这样节水阀锥形出水口 10即成为常开状态, 只需调整控水阀把手 1即可将自动节水龙头作为普通龙头使用。
图 2是本发明第二种实施例的结构示意图; 图 2中,取消了 控水阀 2, 控水阀把手 1, 自锁杆 8上方取消了自锁装置, 只装 有不锈钢弹簧 20, 节水阀 18壳体相对较低, 这样就取消了自锁 方式,既只有取水的手指向上推节水阀按钮 9时才有水流从水龙 头出水口 12流出, 手指离开节水阀按钮 9, 水既关闭, 从而起 到在公共场所强制节水的要求。
