Description

可调式控时水阀 技术领域
本发明是一种可调式控时水阀， 是提供一种可于一定时间内的水压平衡 后， 利用弹性体将推杆推回初始位置， 使水阔关闭的装置设计。 背景技术
红外线控制水阀的应用已经行之有年， 其所应用的原理是使用红外线感 应来控制水阀给水与关水的动作， 然而红外线控制水阀主要是由电子仪器所 组成， 使用时需要电源供应， 且构造复杂及成本高， 因此无法广泛的被使用。
本发明人有鉴于此， 提出有台湾第 0 9 3 1 3 8 6 6 5号 r自闭式控时 水阀」发明专利申请。
请配合参考图 7及图 8所示， 现有的自闭式控时水阀， 其具有外壳体 6 0、 容置体 7 0、 散水片 8 0、 出水隔片座 8 3、 挡水环片 8 5、 控制杆 9 0、 按钮杆 9 3、 控时 0环 9 5与锁固螺栓 9 6；
外壳体 6 0， 其是为两端呈开口状的中空筒体， 并于其内壁的中段处形 成有卡止突部 6 1；
容置体 7 0 , 其顶端形成有容槽 7 1 , 于容槽 7 1的底端面分别形成有 组装孔 7 3与数个水孔 7 2 , 在容槽 7 1的内壁面形成有突出的卡止突缘 7 4 , 而其容置体 7 0的外壁形成有可与外壳体 6 0的卡止突部 6 1相互卡掣 的卡缘 7 5 ;
散水片 8 0 , 其是卡掣于容置体 7 0内部的卡止凸缘 7 4处， 于其中央 形成有开孔 8 1 , 开孔 8 1的周围间隔形成有数散水孔 8 2；
出水隔片座 8 3 , 其是容置于容置体 7 0内部， 并且出水隔片座 8 3的 底端是由散水片 8 0的开孔 8 1处朝向容置体 7 0的底端延伸， 于出水隔片 座 8 3且相对于散水片 8 0的开孔 8 1位置处形成有呈放射状的穿孔 8 4 , 穿孔 8 4下方的开口内壁形成有内锥面；
挡水环片 8 5， 其是设外壳体 6 0内且位于出水隔片座 8 3的上方， 挡 水环片 8 5的中央形成有贯穿孔 8 6 ;
控制杆 9 0 , 其是设置于出水隔片座 8 3的穿孔 8 4内， 控制杆 9 0形 成有穿孔 9 1， 于控制杆 9 0的底端形成有卡掣环片 9 2；
按钮杆 9 3 , 其是贯穿容置体 7 0的組装孔 7 3且位于控制杆 9 0的下 端， 按钮杆 9 3的顶端形成有螺孔 9 4；
控时 0环 9 5 , 是设置于按钮杆 9 3上端及控制杆 9 0的卡掣环片 9 2 之间， 并且其外环壁是与出水隔片座 8 3的穿孔 8 4的内锥面处或与其内壁 相互摩擦；
锁固螺栓 9 6， 其是依序贯穿止水 0环 9 7与控制杆 9 0的穿孔 9 1 , 并与按扭杆 9 3的螺孔 9 4相互螺固。
请配合参考图 9所示， 上述的结构可与一自来水水龙头相互连接， 当按 钮杆 9 3被推入组装孔 7 3与穿孔 8 4内时， 止水 0环 9 7亦会被控制杆 9 0推离挡水环片 8 5的穿孔 8 6处， 此时流体即可由挡水环片 8 5的穿孔 8 6处流入外壳体 6 0内部， 再由容置体 7 0的水孔 7 2流出， 控时 0环 9 5 会于出水隔片座 8 3的穿孔 8 4内朝向容置体 7 0的底端运动， 并且控时 0 环 9 5的外环会与穿孔 8 4的内壁相互摩擦， 此摩擦作用在于使得控时 0环 9 5以一较緩的速度朝向容置体 7 0的底端运动， 藉此使得此水阀得以在一 段时间内呈开启状态， 并可完成清洗的动作。
然而经过一段时间的使用后， 控时〇环 9 5的外环与穿孔 8 4的内壁之 间会产生有磨损的状况， 导致控时 0环 9 5外径缩减， 此时控时 0环 9 5与 穿孔 8 4的摩擦力减小， 因此控时 0环 9 5会以较快的速度朝向容置体 7 0 的底端运动， 所以水阀只能于一较短暂的时间内开启， 如此于出水时间有限 的情况下， 造成清洗动作并不能于此时间内完成， 为了使出水时间延长， 以 便清洗动作可以顺利完成， 按钮杆 9 3就会被一再重复按压或将按钮杆 9 3 按压且维持于一定位， 而使得水阀可维持在较长时间且呈开启的状态， 前述 的按压动作往往会于清洗动作进行时造成相当程度的不便性。 发明的公开
有鉴于前述的现有技术上的不便之处， 本发明是设计一种可调式控时水 阀， 是提供一种利用水压的平衡与弹性体的弹性于一可调整的时间内关闭水 阀的装置。
为达到上述发明目的， 本发明所采用的技术手段为设计一种可调式控时 水阀， 其具有内壳体、 控时装置与上盖， 内壳体的顶端形成有凹槽， 并于凹 槽的底端面形成有穿孔， 控时装置具有推杆、 调整杆、 弹性体与挡水环' 推 杆形成有贯孔， 于推杆的周壁形成有可与贯孔相通的通孔， 推杆的一端是依 序贯穿内壳体的穿孔， 并且延伸至内壳体的回槽内， 调整杆是设置于推杆的 贯孔内， 弹性体的一端是与推杆相互推抵， 挡水环是套设于推杆的顶端处， 挡水环周缘形成侧翼， 上盖是位于内壳体的上方， 于上盖的中央形成有支撑 盖， 支撑盖的内侧面形成有可与弹性体的另端相互推抵的凹槽， 并且 EI槽的 内壁面会与挡水环的侧翼相互接触， 支撑盖的周围形成凹环， 四环的底部形 成有进水孔。
如上述的结构， 当推杆被推入内壳体内时， 来自水龙头的自来水可经由 内壳体的穿孔流出， 此时， 弹性体会受到支撑盖与推杆所压缩， 此时内壳体 的水不断经由推杆的通孔注入， 因而达到支撑盖的凹槽与内壳体的凹槽两者 水压达到相当程度的平衡后， 先前受到压缩的弹性体因不受压力差就可恢复 原状， 弹性体于恢复原状的过程中会提供一回复力， 此回复力会将推杆推回 其初始位置， 如此水阀的关闭的时间是决定于推杆的通孔大小， 通孔越大支 撑盖的凹槽与内壳体的凹槽两者的容室水压越快平衡， 反之通孔越小水压平 衡越慢， 如此清洗动作就得以在设定的时间内完成， 而使其具有使用上的便 利性。 附图的简要说明 图 1是本发明的第一实施例的立体外观分解图。

环体 4 5， 其形成有 槽 4 5 1， 凹槽 4 5 1的内周壁形成有可与推杆
4 4的外螺纹 4 4 8相互螺固的内螺紋 4 5 2 , 藉此将环体 4 5与推杆 4 4 的底端相互连接， 另于凹槽 4 5 1的底端面形成有孔 4 5 3；
上盖 5 0 , 其是设置于基座 1 0的贯孔 1 1内， 上盖 5 0的周缘形成有 可与内壳体 3 0的内突缘 3 4相互卡固的突缘 5 1 , 于上盖 5 0的中央形成 有支撑盖 5 6 , 支撑盖 5 6的内侧面形成有可与弹性体 4 1的另端相互推抵 的凹槽 5 6 1 , 并且凹槽 5 6 1的内壁面会与挡氷环 4 4的侧翼 4 4 1相互 接触， 支撑盖 5 6的周围形成凹环 5 2 , 凹环 5 2的底部形成有进水孔 5 3 , 于凹环 5 2处设有网体 5 4 , 另于上盖 5 0的突缘 5 1处设有上盖环 5 5， 上盖环 5 5是与上盖 5 0的突缘 5 1相互卡掣， 藉此将上盖 5 0固定于基座 1 0处。
请配合参考图 3及图 4所示， 基座 1 0可与一自来水水龙头的出水口相 互螺固， 当推杆 4 4被推入内壳体 3 0内部时， 推杆 4 4就会压缩弹性体 4 1 , 并且会将支撑盖 5 6的凹槽 5 6 1内的水排除， 此动作会造成支撑盖 5 6的凹槽 5 6 1与内壳体 3 0的凹槽 3 2之间的压力差， 此压力差会使得弹 性体 4 1的弹力不足以将推杆 4 4推回， 因此推杆 4 4的 0形环 4 4 3会离 开内壳体 3 0的穿孔 3 3 , 而使得穿孔 3 3呈开启至状态， 此时， 来自水龙 头的自来水会依序经由网体 5 4、 上盖 5 0的进水孔 5 3与内壳体 3 0的穿 孔 3 3 , 而由下盖 2 0的水孔 2 4流出， 如此就可进行清洗的动作。
同时， 自来水亦会充满内壳体 3 0的凹槽 3 2 , 并且此自来水会经由推 杆 4 4的 0形环 4 4 3与支撑盖 5 6的下缘之间的间隙流入至支撑盖 5 6的 凹槽 5 6 1 , 当自来水逐渐充满该凹槽 5 6 1的同时也会经由推杆 4 4的通 孔 4 4 5流入推軒 4 4的贯孔 4 4 4 。
而当推杆 4 4的贯孔 4 4 4、 支撑盖 5 6的凹槽 5 6 1与内壳体 3 0的 凹槽 3 2三者之间水压达到一致时， 先前被压缩的弹性体 4 1因前述的压力 差消失时， 就开始会将推杆 4 4推回其初始位置。
而当经过一段时间后， 推杆 4 4被推回到其初始位置时， 推杆 4 4的 0 形环 4 4 3就会将内壳体 3 0的穿孔 3 3予以封闭， 如此自来水就无法流出 内壳体 3 0 , 藉此达到停止自来水流动的效果， 同时， 自来水会充满于内壳 体 3 0的凹槽 3 2内部及推杆 4 4的贯孔 4 4 4与支撑盖 5 6的凹槽 5 6 1 之间。
而欲使自来水再次流出时， 可将推杆 4 4再次推入内壳体 3 0内， 先前 充满推杆 4 4的贯孔 4 4 4与支撑盖 5 6的凹槽 5 6 1之间的自来水就会迫 使挡水环 4 3的侧翼 4 3 1朝向推杆 4 5方向收缩， 而使其可以流入内壳体 3 0的凹槽 3 2内， 而自来水流动的方向如同前述， 故不赞述。
而欲控制弹性体 4 1的回复力时， 可利用一字起子， 由环体 4 5的孔 4 5 3延伸至推杆 4 4的贯孔 4 4 4内， 插入调整杆 4 3底端的一字槽 4 3 4 内 , 如此可旋转调整调整杆 4 3的位置即调整调整杆 4 3相对于推杆 4 4的 位置， 同时， 由于调整杆 4 3的导水部 4 2 1会因此调整而改变其相对于整 推杆 4 4的通孔 4 4 5的位置， 进而可进一步调整推杆 4 4的通孔 4 4 5大 小， 该通孔 4 4 5越大时， 流入时间越快， 因此消除压力差的时间越短， 反 之通孔 4 4 5越小时消除压力差的时间越短， 因此消除压力差的时间长短关 是着弹性体 4 1的回复力。 综合以上所言， 水阀的关闭的时间是决定于内壳体 3 0、 推杆 4 4与支 撑盖 5 6三者之间的水压平衡与弹性体 4 1的回复力， 而使得水阀的关闭的 时间就得以维持于一定， 如此清洗动作就得以于此时间内完成。
另外， 于其它的实施例中亦可直接将内壳体 3 0及控时装置 4 0与水龙 头的出水口相互结合固定。
请配合参考图 5及图 6所示，其为本发明的第二实施例，于本实施例中， 基座 1 0 A、 下盖 2 0 A、 内壳体 3 0 A、 控时装置 4 0 A与上盖 5 O A的 结构与第一实施例雷同， 故不赘述；
其中， 推杆 4 4 A的贯孔 4 4 4 A内壁且位于其通孔 4 4 5 A与突缘 4 4 6 A的形成有一渐缩部 4 4 4 1 A , 而且调整杆 4 2 A的导水部 4 2 1 A 的尺寸亦呈渐缩状。
因此当自来水由推杆 4 4 A的通孔 4 4 5 A流入贯孔 4 4 4 A内， 再由 贯孔 4 4 4 A流入支撑盖 5 6 A的凹槽 5 6 1 A内时， 其流量会受限于渐缩 部 4 4 4 1 A与调整杆 4 2 A的导水部 4 2 1 A之间的距离， 当二者距离越 近时， 自来水的流量就越小， 因此推杆 4 4 A的贯孔 4 4 4 A、 支撑盖 5 6 A的凹槽 5 6 1 A与内壳体 3 O A的凹槽 3 2 A三者之间水压达到一致的时 间就要较久， 所以弹性体 4 1 A的回复时间就相对的久， 造成水阔开启的时 间就较长， 反之， 当渐缩部 4 4 4 1 A与调整杆 4 2 A的导水部 4 2 1 A之 间的距离越远时， 自来水的流量就越大， 因此推杆 4 4 A的贯孔 4 4 4 A、 支撑盖 5 6 A的凹槽 5 6 1 A与内壳体 3 O A的凹槽 3 2 A三者之间水压达 到一致的时间就要较短， 所以弹性体 4 1 A的回复时间就较快， 造成水阀开 启的时间就较短。
