一种防绕线的感应按钮及具有该感应按钮的排水阀 技术领域
本实用新型涉及马桶排水阀技术领域，尤其是涉及一种防绕线的感应按钮及具有该感应按钮的排水阀。
 背景技术
现有的带感应功能的排水阀感应按钮通常都是先与马桶的水箱盖固定连接后，再通过导线与水箱本体内的外部控制部件电连接，感应按钮采用这种安装方式，不存在导线缠绕的问题。
而当选择感应按钮与马桶水箱内的排水阀主体螺纹连接以锁紧水箱盖和水箱本体时，由于感应按钮锁固在水箱盖上时，水箱盖同时也与水箱本体固定连接，感应按钮安装完成后，水箱盖与水箱本体之间也完成锁固。因此，采用这种方式安装感应按钮，需要在锁紧感应按钮之前就使导线连接感应按钮内的感应元件和水箱本体内的控制部件，而此时，再通过旋转锁固感应按钮，将会导致导线也跟着感应按钮旋转，进而导致导线出现缠绕，感应按钮无法旋紧，或者可能将导线拉断，不方便安装。
 技术问题
本实用新型为了解决上述问题，旨在提供一种防绕线的感应按钮及具有该感应按钮的排水阀，其可避免感应按钮在安装过程中出现导线缠绕的问题，安装更方便、快捷，结构简单。

 本发明的最佳实施方式
为了更清楚地说明本实用新型实施例的技术方案，下面结合附图对本实用新型进一步的说明，下面描述中的附图仅仅是本实用新型的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
如图1至图5所示，本实用新型一实施例的一种防绕线的感应按钮，包括按钮本体10、按键20、感应组件30和导线40。按钮本体10与一固定座110螺纹连接。按键20滑动设置在按钮本体10上，按压按键20可控制与其相应的功能被执行。感应组件30连接导线40，并通过导线40与外部控制部件50连接，感应组件30与外部控制部件50通过导线40进行信号传输，外部控制部件50可以包括控制电路板和电池。感应组件30能与按钮本体10相对转动地装接在按钮本体10上，并且按钮本体10与固定座110螺纹连接时，不带动感应组件30转动，这样，与感应组件30连接的导线40就不会出现缠绕的问题，安装更方便、快捷，结构简单。
本实施例中，按钮本体10包括两端形成开口的中空内套管11，按键20滑动设置在内套管11中，感应组件30能相对内套管11转动地套设在内套管11之外。具体的，感应组件30包括感应元件（未图示）和具有容置腔312的感应壳体31，感应元件设于容置腔312中，感应壳体31与按钮本体10的内套管11能相对转动地套接配合。感应元件可以是红外感应元件或电容感应元件或微波感应元件等。
为了使得感应按钮的整体结构更紧凑，本实施例中，容置腔312沿感应壳体31的周向延伸形成环形容置腔312。按钮本体10还包括顶壁13及间隔地套在内套管11之外的外套管12，内套管11和外套管12的顶端与按钮本体10的顶壁13连接，内套管11、外套管12和按钮本体的顶壁13围成底端开口的环形槽，感应壳体31由环形槽的底端开口套入环形槽中以与按钮本体10能相对转动地套接配合。
具体的，本实施例中，环形容置腔312的侧壁设有沿周向延伸的环形凸筋3122，环形槽的侧壁设有沿周向延伸的卡槽14，通过环形凸筋3122与卡槽14相嵌配合以将感应壳体31与按钮本体10装接在一起。可替换的，也可以是，环形容置腔312的侧壁设有沿周向延伸的卡槽，而环形槽的侧壁设有沿周向延伸的环形凸筋。
感应壳体31的容置腔312的顶端形成开口3121。当采用需要向外射出感应光线的感应元件时，按钮本体的顶壁13对应容置腔312的开口3121处的部分为透光材质制成，从而允许环形容置腔312中的感应元件的光线透出。为了避免水汽经由开口3121渗入容置腔312中而损坏感应元件，在环形容置腔312的侧壁和环形槽的侧壁之间还设有密封圈，通过密封圈使得感应壳体31与按钮本体10实现密封配合。
本实施例中，感应壳体31上设有供导线40穿入容置腔312的穿孔（未图示），导线40与穿孔之间形成密封配合。
本实施例中，感应组件30与固定座在按钮本体10的转动方向上限位配合，从而使得在按钮本体10与固定座110螺纹连接时，不会带动感应组件30转动。具体的，感应壳体31上设有限位块311，固定座110上对应设有限位槽111，通过限位块311和限位槽111的限位配合，使得感应壳体31与固定座在按钮本体10的转动方向上限位配合。可替换的，也可以是感应壳体31上设有限位槽，在固定座110上对应设有限位块。
本实施例中，按钮本体10还包括装饰圈15，装饰圈15采用螺纹连接可拆卸地安装在按钮本体10上，这样当按钮本体的顶壁13采用透光材质制成时，而装饰圈15则不需要采用透光材质制成，比如装饰圈15可以采用容易电镀的材质制成，通过电镀工艺使得装饰圈15更美观。
装配时，首先将感应元件装入感应壳体31的容置腔312中，将导线40的一端与容置腔312中的感应元件连接，使导线40的另一端经由感应壳体31上的穿孔伸出。接着，将感应壳体31与按钮本体10的环形槽套接，将按键20滑动设置在按钮本体10内。然后，将导线40从容置腔312中穿出的一端与外部控制部件50连接。最后，转动按钮本体10使得按钮本体10与固定座110螺纹连接，在此过程中，由于感应组件30不会随着按钮本体10转动，因此也不会带动导线40，从而避免了导线40缠绕的问题。
本实用新型还提供一种排水阀100，固定安装在具有水箱盖的马桶水箱（未图示）内，包括上述任一项所述的防绕线的感应按钮，固定座110固定在排水阀的阀体120上，按钮本体10能转动地设于水箱盖的安装孔处，按钮本体10与固定座110螺纹连接时，将水箱盖与马桶水箱的箱体（未图示）固定连接。外部控制部件50可以选择固定在排水阀100的阀体120上或马桶水箱的箱体内的其他位置上。本实施例中，外部控制部件50包括控制电路板（未图示）和对控制电路板进行供电的电池（未图示），控制电路板和电磁均装接在一外壳内，导线40穿过外壳与外壳内的控制电路板电连接，外壳采用可拆卸地方式固定在排水阀100的阀体120的外侧壁上。
尽管结合优选实施方案具体展示和介绍了本实用新型，但所属领域的技术人员应该明白，在不脱离所附权利要求书所限定的本实用新型的精神和范围内，在形式上和细节上对本实用新型做出各种变化，均为本实用新型的保护范围。
