技术领域
本申请涉及检测设备领域，尤其涉及一种探测电极的安装结构、水检测器及其加工方法。
背景技术
在现代人的生活工作场景中，漏水常有发生，如饮水机漏水、水管漏水、屋顶漏水等，漏水给人的生活和工作带来不便；此外，由于电器普及率的不断提高，各场所漏水导致安全隐患的发生率也随之增加。小至房屋进水大至因水造成电路短路而引起的触电、火灾等，为此，人们创造了水检测器对各种漏水情况进行检测报警，为人们的生活和工作都带来保障。
然而，现有的水检测器普遍体积过大，导致一些狭窄的区域放不下水检测器，使其使用场所受限；另外，现有技术中水检测器只能单面检测，如果水检测器不小心翻身或者不处在水平面上，则无法正常工作。
有鉴于此，亟需一种新的技术方案来解决上述技术问题。

本实施例提供一种探测电极的安装结构，包括绝缘壳体及四个探测电极，绝缘壳体包括四个探测面，四个探测电极分别埋设在四个探测面之间的连接棱上，四个探测电极两两一组，两组探测电极配置成分别连接信号线电极和电源电极，且位于对角位置的两个探测电极均连接同一个电极。
请参阅图1-图3，本实施例揭示了一种水检测器，其包括绝缘壳体、电池5、电路板及四个探测电极。绝缘壳体包括四个探测面，四个探测电极分别埋设在四个探测面之间的连接棱上，电路板上设有检测电路，检测电路包括信号线电极和电源电极；四个探测电极两两一组，两组探测电极配置成分别连接信号线电极和电源电极，且位于对角位置的两个探测电极均连接同一个电极，即位于对角位置的一对探测电极是相连的，四个探测电极的其中一组探测电极连接信号线电极，另一组探测电极连接电源电极；电池5及电路板均安装在绝缘壳体内。该水检测器采用了上述探测电极的安装结构。
可选地，本实施例中，绝缘壳体包括上壳1、下壳2及连接壳3，上壳1及下壳2分别固定连接在连接壳3的两端；上壳1远离连接壳3的一端封闭，下壳2远离连接壳3的一端具有敞口，该敞口处封盖有一电池盖4。上壳1、下壳2及连接壳3内部均形成有配置成装设其它组件的安装空间。
可选地，所述上壳1、下壳2及连接壳3的横截面均为正方形；上壳、连接壳和下壳沿所述绝缘壳体的长度方向排布，上壳的长度与下壳的长度相等，且上壳及下壳的长度大于连接壳的长度，上壳1和下壳2的高度相当，连接壳3的高度最小，因此三者组成的绝缘壳体呈长条方形，绝缘壳体的四个侧面即是所述的四个探测面。
作为一种优选的方案，为了使整个水检测器外观更加圆滑、美观，而将绝缘壳体的面与面之间的连接棱做圆角处理。
本实施例的绝缘壳体具有四个探测面，四个探测电极分别埋设在四个探测面之间的连接棱上，当任一探测面位于平面上时，总有两个不同极性的探测电极也位于该平面上，一旦平面有水即可触发电路，实现水检测功能，性能可靠；即便不小心碰到水检测器而使其发生翻滚，水检测器总有一个探测面贴于平面，使得位于该探测面的两个不同极的两个探测电极处于能正常工作的位置，因此，本水检测器具备应对碰触翻滚的机制，容错率更高。
请参阅图3，作为一种优选的方案，连接壳3的上下两个端面均开设有一圈凹槽32，上壳1连接连接壳3的端面凸设有一圈卡缘，定义该卡缘为第一卡缘11；下壳2连接连接 壳3的端面也凸设有一圈卡缘，定义该卡缘为第二卡缘22，装配时，上壳1的第一卡缘11和下壳2的第二卡缘22分别插置于连接壳3的凹槽内，用以增强三者的连接稳固性，同时增强绝缘壳体的防水性能。
需要说明的是，本实施例中绝缘壳体是由三个部分沿着纵向方向(即绝缘壳体的长度方向)组装而成，但本申请的绝缘壳体并不限定于此，其它的组装形式例如由两个部分沿着纵向方向组装而成、或者由两个部分沿横向方向组装而成均可。此外，本申请中“上壳”、“下壳”仅用于部件名称的区别，并不限定其使用方位。
请参阅图3，可选地，上壳1与下壳2的横截面相等，连接壳3的横截面小于上壳1的横截面，即三个壳体当中，连接壳3的横截面最小，上壳1和下壳2的横截面相等。装配后，上壳1朝向所述连接壳3的端面、连接壳3的外壁与下壳2朝向连接壳3的端面形成环状的虹吸槽31；四个探测电极均位于虹吸槽31内。虹吸槽31沿绝缘壳体的周向环设，即绝缘壳体的四个探测面均存在虹吸槽31的槽体，该虹吸槽31的作用在于：水检测器的一个探测面贴在检测平面时，当该检测平面上存在水体时，该探测面上的虹吸槽31的内凹状的槽体会产生虹吸作用，水体趋向于汇聚至探测面的槽体内，位于该探测面的两个探测电极与水体接触形成通路，从而快速引发水检测器工作，提高水检测器的检测灵敏度；同时，探测电极位于虹吸槽31的内缩槽体内，虹吸槽31可以对探测电极起到保护作用，减少甚至避免外界因素对探测电极造成的碰撞损坏，从而延长探测电极的使用寿命，确保水检测器的正常使用。可选地，虹吸槽31位于绝缘壳体的中部位置。
可选地，可以在连接壳3的四个连接棱处均设置插置孔，四个探测电极一一对应插接于四个插置孔内，且四个探测电极均露出所述连接壳3的外表面。这里是探测电极连接于连接壳3的一种具体形式，具体地，探测电极的外表面可以与连接壳3的外表面一致，一方面，能够减少探测电极凸出连接壳3外部受外界因素碰撞损坏情况的发生；另一方面，也能够保证探测电极的外表面能够与虹吸槽31内的水体充分接触，确保其检测功能。
如图1和图2所示，连接壳3的连接棱为圆角设置以形成弧形面，探测电极的外表面相应也为弧形面，连接棱的弧形面与探测电极的弧形面共面设置，其中，探测电极的弧形面向两侧延伸至两个探测面，从而确保两个探测面中任一者与检测平面贴合时，连接棱上的探测电极均能够起到检测作用。
可选地，上壳1与连接壳3、下壳2与连接壳3之间可以采用超声波熔接工艺连接，此种连接方式用于确保整个绝缘壳体具备优良的防水性能，减少水体进入绝缘壳体内部对其内的电路等造成浸泡短路情况的发生，从而确保水检测器的正常使用。
可选地，本实施例中，电路板可以包括主电路板61及副电路板62，主电路板61和副电路板62电性连接；主电路板61安装在上壳1内，副电路板62安装在连接壳3内。具体 的，主电路板61插置固定于上壳1内，副电路板62以平行连接壳3横截面的方式安装在连接壳3内，此种安装方式可最大化利用空间，使整个水检测器结构更加紧凑，有利于其小型化。具体地，水检测器的长×宽×高可以为21.6mm×21.6mm×67mm，水检测器的体积小巧，能够应用于空间狭小的角落等区域，从而减少水检测器的使用限制，提高其适用性。
可选地，本实施例中，可以在电池盖4的内侧固定装有负极弹簧41，电池5通过负极弹簧41挤压安装在下壳2内，且电池5的正极连接于副电路板62，电池5的负极连接于负极弹簧41；具体可以为：电池5的正极朝前插入下壳2的内部安装空间，再将电池盖4的负极弹簧41抵在电池5的负极，用两个螺丝钉42将电池盖4固定在下壳2的端部，从而将电池5装配到位；需要更换电池5时，只需将螺丝钉42旋出，将电池盖拆下，对电池5进行更换即可。
本水检测器由电池5提供电力，无需外接电源，水检测器的使用不受插座的限制，从而使本水检测器的使用场所大大扩展。同时，电池5、主电路板61及副电路板62均安装在绝缘壳体内，结构紧凑、体积小，使得本水检测器能够放置到一些狭窄的场所，进一步扩大它的使用场所。
可选地，下壳2内可以设置楔形块21，楔形块21固定安装在电池5与下壳2之间的空隙，楔形块21设有通孔，通孔沿着下壳2的纵向延伸。通孔内穿设有一可伸缩的探针8，探针8的一端固定连接于其中一组探测电极，探针8的另一端弹性连接于负极弹簧41。
需要说明的是，本实施例是将电源的负极连接其中一组探测电极，并以这一组探测电极作为电源电极；容易想到的是，在其它实施例中，还可以是将电源的正极连接一组探测电极，并以这一组探测电极作为电源电极。
请参阅图4及图5，本实施例中，四个探测电极可以为四个金属片7，连接壳3具有四个表面，四个金属片7分别埋设在相邻两个探测面的连接棱上；具体是：在连接壳3的四个角处开设四个插置孔，插置孔的尺寸与金属片7相匹配，金属片7插置固定于对应的插置孔内。四个金属片7与连接壳3所在的平面共面，四个金属片7均露出于连接壳3的外表面，且露出的部分与连接壳3的外表面平齐。
请参阅图6，四个金属片7分别标记为探测电极A、探测电极B、探测电极C和探测电极D，其中探测电极A和探测电极C相连，并连接于电源电极，如电源负极；探测电极B和探测电极D相连，并连接于信号线电极。由此，任意相邻的两个金属片7为不同极性，当任一个探测面位于检测平面上时，总有两个不同极性的金属片7也位于该检测平面，一旦检测平面有水即可触发回路，实现水检测功能，性能可靠。
上述探测电极A和探测电极C相连、探测电极B和探测电极D相连的具体实现方式为： 四个金属片7均设有焊接柱71，每个焊接柱71均向副电路板62一侧延伸，焊接柱71焊接于副电路板62上。其中，探测电极A和探测电极C的焊接柱71在副电路板62上通过第一条线路连接，探测电极B和探测电极D的焊接柱71在副电路板62上通过第二条线路连接，第一条线路与第二条线路互不相连，至此，四个金属片7实现本申请的特殊连接关系；其中，第一条线路连接PNP三极管的基极，基极通电阻上接到电源(电源正极或负极)；第二条线路连接信号线电极。
本实施例中，水检测器的内部检测电路主要是利用PNP三极管的特性来实现漏水检测的，具体为：在没有水导通信号线电极和电源电极时，PNP三极管的基极位于高电位，三极管不触发；当水作为介质导通信号线电极和电源电极时，基极电位被拉低，三极管被触发，从而实现水检测功能。PNP三极管的上述特性为本领域常规知识，本实施例对此不再赘述。
可选地，电路板包括报警模块，具体地，报警模块可以为蜂鸣器，且该蜂鸣器安装在主电路板61上。当水检测器检测到水时，蜂鸣器将被触发并发出鸣叫，提醒用户注意。
需要说明的是，报警模块并不仅限定于本实施例的蜂鸣器，还可以是其它的组件，比如警报器、闪灯器等。
可选地，电路板还可以包括发送模块，发送模块配置成向水阀控制器发送控制指令，进而控制水阀打开或关闭；或者向用户发送检测信息。具体的，水阀控制器可以控制水龙头的开闭，也可以控制其它用水电器的开闭。
可选地，电池盖4与下壳2之间还设有防水圈10。具体的，可以在下壳2的端面上开设有一圈嵌槽23(又名凹槽)，防水圈10挤压密封于该嵌槽23与电池盖4的内侧表面所形成的空间内。此外，嵌槽23也可以开设在电池盖4的内侧表面，或者在下壳2和电池盖4的装配面上均开设有嵌槽23。嵌槽23的设置，一方面，能够对防水圈10起到限位作用，以减少防水圈10从电池盖4与下壳2之间偏移甚至脱落情况的发生；另一方面，防水圈10的表面与嵌槽23配合挤压，防水圈10与嵌槽23的接触面积增大，从而提高防水圈10的密封放水效果，提高电池盖4与下壳2的连接密封性，减少水体经电池盖4与下壳2之间的间隙进入下壳2内部对电路造成的浸泡短路，进一步确保水检测器的正常使用。
请参阅图1-图3，本实施例中的四个金属片7装配后位于绝缘壳体的同一横截面，此种结构设置是最方便安装、且最易于制作的结构。具体在本实施例中，四个金属片7可采用以下方式来制作及安装：
请参阅图4及图5，选取一块五金片对其进行冲压，得到一X形五金片，该X形五金片包括一个中心,72、连接中心圆72的四条连接边73及连接四条连接边73的四个薄片，每个薄片的一侧边向中心圆方向延伸形成一延长边，延长边再向垂直于五金片所在平面的 方向弯折形成弯折部，最后将中心圆72和连接边73进行切除即可。薄片即为金属片7，弯折部即为焊接柱71，此种制作工艺可一次性得到四个金属片7，加工便捷，有利于提高生产效率。需要说明的是，上述“薄片”仅用于表示金属片为片状体，为金属片厚度与表面积的一个相对概念，对金属片的厚度并无限定。
装配时，可以将四个金属片7对应插置于预先开设有插置孔的连接壳3上，即可完成装配。
需要说明的是，本实施例中的探测电极是金属片7，但根据本申请的发明主旨，探测电极并不局限于金属片7，还可以是金属块、金属柱等。而且，四个探测电极的位置并不限定为位于同一个横截面平面内，只要确保每个探测面贴在一检测平面上的同时，有两个探测电极也位于该检测平面内即可。
本水检测器的工作原理及过程描述如下：
本水检测器用作漏水检测时，将其平放在地面上，此时，水检测器的其中一个探测面贴着地面，与此同时位于该探测面的两个连接棱上的探测电极也贴着地面。当地面上有漏水时，两个探测电极通过水实现连接导通，同时触发水检测器的内部检测电路，从而达到漏水检测的目的。容易理解的是，本水检测器的形状是长条方形，即便被不小心碰触，水检测器也是绕其长度方向的轴滚动，最终必定会有一个探测面贴着地面，从而确保两个探测电极处于能够检测到漏水的位置。值得一提的是，漏水检测并不局限于放置在地面上，还可以是其它的位置，比如桌面、窗台或者其它可能存在漏水的平面。
本水检测器除用于上述漏水检测外，还可用作水位检测，以水池注水为例，具体使用方法如下：
1、将水检测器竖直装在水池壁的某一高度，然后打开水阀开始注水；
2、当注水量达到一定程度时，水面将浸没水检测器的四个探测电极，而一旦水检测器的至少两个不同极性的探测电极导通便可触发其内部电路，进而触发蜂鸣器发出鸣叫声，提醒用户关水阀。
在其它实施例中，当水位达到预定值时，水检测器的发送模块向水阀发送动作指令，关闭水阀、停止注水；或者，水检测器的发送模块直接向用户的移动终端发送检测信息，提醒用户水位已达到预定值。
综上所述，本申请将四个探测电极分别埋设在四个探测面之间的连接棱上，当任一个探测面位于平面上时，总有两个不同极性的探测电极也位于该平面上，一旦平面有水即可触发电路，实现水检测功能，性能可靠；本申请的水检测器采用电池提供电源，并将电池和电路板安装在绝缘壳体内部，结构紧凑、体积小，使用场所多；本申请不仅可用作漏水检测，还能用作水位检测，性能稳定可靠、适用性高。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
尽管上面已经示出和描述了本申请的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本申请的限制，本领域的普通技术人员在本申请的范围内可以对上述实施例进行变化、修改、替换和变型。
