为了实现如厕后小便器自动冲水的功能，已开发出多种感应模式的感应器来分别满足不同使用需求，其中，最传统的技术是在小便器上设置红外传感器，其工作原理是红外发射器发射一定波长的红外线，经靠近小便器的人体或物体反射后，通过红外接收器接收并判断反射信号的强弱来实现自动感应冲水。通常，红外传感器布置在小便器上额外设置的空间内，需要考虑排线布局等因素。此外，已意识到的是，红外感应方式易受环境影响，无法准确判断目标物的存在，容易误冲水，造成水资源浪费。
在某些采用能够精确判断是否冲水的感应器的方式中，例如电容感应器或者电导(或电感)感应器，由于感应器成本的增加，使得具有这种感应器的小便器不能普遍应用，限制了产品通用率。并且，这种感应器往往设置为与小便器内的液体接触，导致污物沉积而影响检测性能，不利于后期使用和维护。
由此，本公开旨在提供一种模块化感应冲水装置，通过将感应组件模块化，基于不同需要替换不同感应模式的感应模块，例如红外感应组件、电导感应组件、电容感应组件中的至少两种，从而使得小便器适用于多种场合。
图1示例性示出了一种结构形式的小便器10，例如由陶瓷制成，并包括便池体11，然而其结构/尺寸/外形并不作为限制。通常，结合图10所示，具有自动冲水功能的小便器形成有容置液体的内腔12，内腔12的内壁上开设有用于安装冲水喷头的开口13，并在底端开口以提供用于容纳控制组件的容纳空腔14，某些情形下还设有盖板16以打开或关闭容纳空腔14。本文中，小便器背面指小便器用于安装至墙体的一侧，正面指朝向用户的一侧，在描述内腔12和容纳空腔14时，内壁指朝向腔室内部的一侧。
结合图2至图4所示的第一种实施方式，小便器10通过安装组件200固定至墙体，安装组件200例如包括一对安装片210以及相应的紧固件，例如紧固螺栓220。根据本公开的模块化感应冲水装置300组装在小 便器的容纳空腔内，并包括进出水组件、排水组件350、电磁阀组件310以及电源组件340。其中，电磁阀组件310控制水路通断，包括电磁阀311，与电磁阀311连接的进水接头(未图示)和出水接头312。电源组件340为外接交流电源或直流电池盒，经导线与电磁阀组件310连接以提供动力。进出水组件包括进水管320和出水管330，进水管320具有第一进水端321以连接外部水管以及第一出水端322以连接进水接头，出水管330具有连接出水接头312的第二进水端331以及连接冲水喷头333的第二出水端332。如图4所示，冲水喷头333通过连接端3331与第二出水端332可拆卸地连接并至少设有冲水口3332，由于冲水喷头333布置在小便器10的上方，冲水口3332朝向下方的内腔12布置。
结合图4和图13所示，排水组件350包括入水端口351、排水端口352以及连接于两者之间的弯管353，其中，入水端口351密封连接小便器的排水管口15(图10)的外部，并通常设有密封胶片360(图3)。弯管353用于存水以起到防臭作用。
在第一种实施方式中，如图4所示，感应模块为红外感应组件390，包括与电磁阀组件310连接的红外感应控制器391，以及通过导线392与红外感应控制器391连接的红外感应头393，红外感应头393附接于进出水组件。具体地，红外感应头393具有与导线392连接的供电端394，以及附接于冲水喷头333的感应端395，其中，冲水喷头333设有供感应端395外露的槽口3333，用以提供红外感应模式下的感应窗口。
在该实施方式中，由于将红外感应头的感应端集成在冲水喷头处，安装及使用时不与出水管330发生干涉，从而在不影响冲水性能的同时有利地利用了冲水喷头处以及小便器的容纳空腔内的空间，无需额外配置用于红外感应头的安装空间。此外，红外感应头的位置也与用户的常规使用位置相对应，感应检测更为准确，当感测信号发送至红外感应控制器后，红外感应控制器发送信号至与其连接的电磁阀组件，进而电磁阀组件控制冲水阀开启，实施冲水，从而以最为经济的成本改善了现有的红外感应模式的小便器。
如上所述的，本公开的构思在于感应模块/感应模式的可替换，在第一种实施方式满足大多数用户使用需求的基础上，本公开的模块化感应 冲水装置能够通过替换不同感应组件和/或冲水喷头而获得模块化的通用小便器。
以下参见图5至图11所示的第二种实施方式，与上述实施方式的区别在于感应组件以及冲水喷头的不同，因此，相同的部件不再赘述。
在该实施方式中，感应模块为电导感应组件500，包括与电磁阀组件连接的电导感应器520。在某些实施方式中，电导感应器520有利地集成有电极，从而例如通过无线通信方式实现将感测信号发送至电磁阀组件而无需增设导线。如图10所示，电导感应组件500适于邻近排水组件附接至小便器背面的内壁，例如通过粘接剂的方式，并且电导感应组件不与小便器内的液体接触。已知的是，水和尿液的电感的导电率不同，尿液含有盐分，导电率会更大，因而采用电导感应模式更易于检测出水和尿液的区别。应理解的是，虽然本文中以尿液作为小便器内液体中区分清水的检测物质，本公开亦可适用于其他排泄物或呕吐物等污物的检测。
所示实施方式中，电导感应组件通过粘接方式邻近排水组件便捷地附接至小便器背面的内壁，当用户使用小便器时，能够准确感测小便器的内腔中壁面上是否有尿液流过，从而提供感测信号给电磁阀组件，实现冲水。对于清洗小便器时使用的清水或洁厕液等液体，则不会触发电导感应组件产生信号，避免误冲水造成的水资源浪费。在该感应模式下，电导感应组件采用不与液体接触的方式，避免了尤其电导感应器由于污垢导致的感应失效问题。在某些实施方式中，如果排水组件由于例如污垢过多而发生堵塞，邻近排水组件布置的电导感应组件同样能够感应并检测出导电率的变化而对电磁阀组件提供准确的信号，避免继续冲水导致水溢出或飞溅影响用户使用舒适度。
在某些实施方式中，电导感应组件500还包括感应器支架510，结合图8和图9所示，感应器支架510设有供容置电导感应器520的卡槽511并可通过粘接剂附接至小便器背面的内壁。有利地，感应器支架510具有与小便器背面的内壁轮廓适配的外表面，以使得电导感应组件紧贴小便器背面的内壁。此种方式下，电导感应器520可拆卸地容置于卡槽511内，或者也可采用胶水将卡槽511填满，以使得电导感应器与被感测的壁面之间不存在间隙，保证检测结果的准确性。采用电导感应器520可 拆卸安装的方式，在电导感应器520失效更换等情况下，便于将电导感应器520从感应器支架510上拆卸而保留感应器支架510于小便器上，用以供新更换的电导感应器使用。
采用电导感应模式，解决了红外感应模式需要感应窗口的不足，以及感应失灵的缺陷，具有高检测灵敏度和快速响应度的优势。电导感应组件易于拆卸和组装的特性使得用户能够在模块化感应冲水装置组装至小便器之前或之后自行替换，从而对小便器进行更新换代，或者是将不同的感应模式进行叠加。举例来说，当用户期望叠加两种感应模式时，将电导感应组件粘接至小便器背面的内壁即可，方便快捷，从而通过电导感应组件弥补红外感应组件的不足。在仅采用电导感应模式的实施方式中，可将图3所示的第一种实施方式的冲水喷头333替换为图6所示的第二种实施方式的冲水喷头433。如图7所示，冲水喷头433同样具有连接至出水管的连接端4331和朝向下方的冲水口4332，但不具有感应窗口。由此，用户仅需更换冲水喷头将红外感应头遮覆，并将电导感应组件500粘接至小便器背面的内壁即可，或者可选地再将红外感应组件拆除，无需对整个冲水装置进行更换，成本经济。
图12至图13示出了本公开的第三种实施方式，同样，该实施方式与上述实施方式的不同之处在于感应组件的不同，因而，相同的部件不再示出且相同的描述不再赘述。
在该实施方式中，感应模块为电容感应组件600，包括与电磁阀组件连接的电容感应器610以及与电容感应器连接的电极。电容感应器610可拆卸地粘接于排水组件，例如通过胶带或魔术贴直接粘接于弯管353，便于使用时固定及后期维护更换时的拆卸。电极例如通过胶带附接至排水组件的入水端口351，并优选沿排水方向依次布置至少两个电极，图中示例性示出贴在排水组件的入水端口351处的第一电极620和第二电极630，两个电极同时收到固定的信号脉冲才触发控制，实现抗干扰的功能。有利地，电极布置在入水端口351的外壁，从而不与小便器内的液体接触，避免污垢引起的感应失效。
如图14、图15所示，排水组件的入水端口351和小便器的排水管口15的连接处设有密封塞，例如橡胶塞800，橡胶塞800起到塑料排水组 件和陶瓷小便器之间的密封作用。同时，橡胶塞800也从外侧包裹住前述的第一电极620和第二电极630，防止水和湿气进入到电极上去，影响电容感应信号，从而提高了感应器的工作稳定性和可靠性。
已知的是，水和尿液的溶质有差异，弯管内是否有水也会对溶质电容产生影响，电容感应模式适于准确感测尿液溶质的变化，并且适于感测排水组件处是否堵塞，避免溢水。当污物通过排水组件的入水端口351流入弯管353，使得弯管353内的液体的溶质电容发生变化，电容感应组件感测到变化信号后，发送信号至电磁阀组件，从而控制冲水阀开启，实施冲水。当水静止不动达到类似淹没电极的水平后，亦可获得感测信号，不会继续冲水导致溢水。
类似地，取决于不同应用场景和/或用户需要，该实施方式的电容感应组件同样适于与上述的红外感应组件和/或电导感应组件替换使用或者叠加使用。
除了感应模块的可替换设计，本公开还对模块化感应冲水装置在小便器内的固定方式进行了改进。通常，电磁阀组件和电源组件安装于小便器背面的容纳腔室内，且容纳腔室位于便池体的底部，需要维修或更换时，存在拆装不便的问题。
回到图3和图4可以看出，排水组件350的排水端口贯穿安装盘380而与外部排污管道连通，安装盘380例如通过螺钉等紧固件固定于墙体。在如图所示实施方式中，电磁阀组件310、电源组件340和例如红外感应组件390组装于支架370上以集成为单一模块，支架370可通过例如螺钉371直接固定于小便器背面的内壁，例如盖板16上，以利于拆卸来实现更换电池等维护操作。
在某些实施方式中，如图14至图16所示，支架可通过连接架固定于安装盘。具体地，在该实施方式中的支架710包括底板711以及从底板711平行和/或成角度延伸出的至少一个支撑板，例如图16所示从底板711平行延伸出的第一支撑板713和垂直延伸出的第二支撑板712。各个支撑板设有大致平行于底板711延伸出的支撑悬梁714和/或支撑环扣715、716，以用于固定电磁阀组件、电源组件和/或感应模块。以这种方式，通过支架将上述各组件集成为模块，并如图14所示结合连接架720来简化 拆装、提高效率。
支架与连接架之间的固定可选为紧固件连接、粘接或卡接等适当的方式。在某些实施方式中，如图15所示，连接架720构造为例如通过螺钉等紧固件贴附固定于安装盘380的连接板721，并设有从连接板721突伸出的一对卡接肋723。相应地，支架710包括从底板711成角度延伸出的安装凸耳717，以适于可拆卸地卡接入一对卡接肋723中。可选地，连接架720构造为Y型，包括与排水组件形成避让的缺口722。
通过上述对模块化感应冲水装置的固定方式的改进，当需要维修或更换电磁阀组件、电源组件和/或红外感应控制器时，仅需拆卸支架即可，操作便捷，这也使得本公开的模块化感应冲水装置适于更为多样化的产品设计。
这里应当理解的是，图中所示实施方式仅显示了根据本公开的模块化感应冲水装置的各个可选部件的可选架构、形状、尺寸和布置方式，然而其仅为示意而非限制，在不背离本公开的思想和范围的情况下，亦可采取其他形状、尺寸和布置方式。
以上已揭示本公开的技术内容及技术特点，然而可以理解，在本公开的创作思想下，本领域的技术人员可以对上述公开的构思作各种变化和改进，但都属于本公开的保护范围。上述实施方式的描述是例示性的而不是限制性的，本公开的保护范围由权利要求所确定。
