具体实施方式
下面结合附图和实施例对本申请进行说明。
图1为本申请实施例提供的一种电路板的打印材料容器接触面的结构示意图，参考图1，电路板10，安装在打印材料容器上，电路板10包括原始电路板101和辅助部102，原始电路板101包括多个端子1011，端子1011设置为与打印材料容器接触或与打印设备接触；辅助部102设置于原始电路板101上，设置为提供导电通路和/或阻断端子1011之间的导电通路。
打印设备例如可以是喷墨打印机，其具有打印材料容器(墨盒)以及打印材料容器对应的电路板，打印设备通过电路板识别打印材料容器中打印材料的剩余量(剩余墨水水平)；打印设备上包括多个设置为与电路板上对应端子接触以实现电连接的芯片侧端子，墨盒上可包括设置为检测墨盒中剩余墨水水平的传感器，传感器上包括设置为与电路板上对应端子接触以实现电连接的芯片侧端子；当电路板安装在墨盒上时，墨盒上的芯片侧端子与电路板上对应的端 子实现电连接；当墨盒以及电路板安装到打印设备中时，打印设备上的芯片侧端子与电路板上对应的端子接触以实现电连接，从而使得打印设备中的主控制器能够通过电路板获取墨盒的相关信息，如获取墨盒中的剩余墨水水平，使得打印设备根据剩余墨水水平执行相应的操作。电路板例如可以是印刷电路板(Printed Circuit Board，PCB)，印刷电路板可为单层或多层结构，印刷电路板上的端子示例性的可为焊盘。
原始系列打印设备中电路板上多个端子之间的连接关系可能与目标系列打印设备中电路板上多个端子之间的连接关系不同，如原始电路板上两个端子之间不存在导电通路，而目标系列打印设备中电路板上对应的两个端子上需要存在导电通路，在将原始系列打印设备中的电路板(原始电路板)回收之后，可根据目标系列打印设备中电路板的结构对原始电路板进行改造，如在原始电路板上制备辅助部，以使得得到的新电路板对应的两个端子之间存在导电通路，进而使得目标系列的打印设备能够识别出利用原始电路板制作而成的电路板；又例如原始电路板上两个端子之间存在导电通路，而目标系列打印设备中电路板上对应的两个端子上不能够存在导电通路，则可利用辅助部将原始电路板上的该导电通路阻断，从而使得目标系列的打印设备能够识别出利用原始电路板制作而成的电路板，也即完成了原始电路板的跨代利用，极大的提高了原始电路板的回收利用率，从而能够降低打印设备中电路板的成本，进而降低打印设备的成本。
原始系列打印设备相对于目标系列打印设备可以是旧系列，也可以是新系列，本申请实施例对此不做限定。
本实施例的技术方案，采用的电路板包括原始电路板和辅助部，原始电路板包括多个端子，端子设置为与打印材料容器接触或与打印设备接触；辅助部设置于原始电路板上，设置为提供导电通路和/或阻断端子之间的导电通路。可根据目标系列打印设备中电路板的结构对原始电路板进行改造，如在原始电路板上制备辅助部，以使得得到的新电路板对应的两个端子之间存在导电通路，和/或使得新电路板上对应的两个端子之间的导电通路阻断，进而使得目标系列的打印设备能够识别出利用原始电路板制作而成的电路板，也即完成了原始电路板的跨代利用，极大的提高了原始电路板的回收利用率，从而能够降低打印设备中电路板的成本，进而降低打印设备的成本。
可选地，辅助部设置为提供导电通路，且辅助部呈阻性。
在原始系列打印设备的原始电路板中，两个端子之间不存在导电通路，而在目标系列打印设备的电路板中，对应的两个端子之间不仅存在导电通路，且对应的两个端子之间需要有一个电阻才能够被目标系列打印设备识别，因此， 可设置辅助部呈阻性以使原始电路板添加辅助部后能够应用到目标系列的打印设备中。
可选地，辅助部包括碳油或阻性的分立元件。
碳油和阻性的分立元件均能够使得对应的两个端子之间形成导电通路，当辅助部设置为提供导电通路时，辅助部可以为碳油，碳油容易在原始电路板上涂覆，且厚度较小，所占用的整体空间较小，不会影响电路板整体所占用的空间，也即不会使得电路板的尺寸因发生较大变化而无法与墨盒或打印设备匹配。同时，可通过控制碳油的尺寸来控制碳油的阻值，进而对电路板上相应端子之间的阻值进行控制，以使得目标系列的打印设备能够识别利用原始电路板制作而成的电路板。
可选地，辅助部为碳油，电路板还包括绝缘膜，绝缘膜覆盖至少部分辅助部。
当辅助部采用碳油时，由于碳油较薄，长时间使用可能会因为磨损或水氧腐蚀等，使得碳油之间存在断点，可能会造成导电通路断开，进而使得对应的打印设备无法识别出该电路板。通过设置绝缘膜，如当碳油仅仅作为两个端子之间的导电通路时，可利用绝缘膜完全覆盖碳油；而当碳油还要作为端子的功能使用(即碳油需要与打印材料容器或打印设备上对应的芯片侧端子接触以实现电连接)，绝缘膜可对碳油上作为端子功能以外的部分进行覆盖，以防止碳油因磨损或水氧腐蚀等损坏，极大的延长了电路板的使用寿命。
可选地，继续参考图1，原始电路板101包括第一传感器连接端子A1和第二传感器连接端子A2，第一传感器连接端子A1及第二传感器连接端子A2均设置为与打印材料容器接触；辅助部包括第一辅助部1021，第一辅助部1021与第一传感器连接端子A1及第二传感器连接端子A2连接，设置为提供第一传感器连接端子A1与第二传感器连接端子A2之间的导电通路。
图2为本申请实施例提供的一种电路板与打印设备及芯片电连接的电路结构示意图，结合图1和图2，第一传感器连接端子A1和第二传感器连接端子A2均设置为与传感器连接，打印设备上包括设备侧电路401以及芯片侧端子(将在以下描述)，原始电路板101例如可以是原始系列打印设备上的电路板，原始电路板101上的第一传感器连接端子A1和第二传感器连接端子A2之间可能不存在导电通路，而目标系列打印设备上电路板对应的第一传感器连接端子A1和第二传感器连接端子A2之间需要有导电通路，则可通过设置第一辅助部1021，将第一传感器连接端子A1与第二传感器连接端子A2之间导通，例如，第一辅助部1021的阻值符合目标系列打印设备的电路板上对应端子之间的阻值，以使得原始电路板101添加第一辅助部1021后能够与目标系列打印设备兼容，进而 完成原始电路板101的再次利用，降低打印设备的整体成本。本申请实施例对第一辅助部1012的形状不做限定，只要能够使得第一辅助部1012的阻值满足需求即可。第一辅助部1012可完全覆盖或者部分覆盖第一传感器连接端子A1及第二传感器连接端子A2，以使得第一辅助部1012与第一传感器连接端子A1及第二传感器连接端子A2具有较大的接触面积，提高接触性能，防止接触不良等现象。
可选地，继续参考图1，原始电路板101还包括位于第一传感器连接端子A1与第二传感器连接端子A2之间的限位孔1012；第一辅助部1021的边缘距离限位孔1012边缘的最小距离大于或等于预设距离。
限位孔1012可设置为将电路板10固定在打印材料容器上，限位孔1012的形状可为圆形、矩形或其他多边形等，在设置第一辅助部1021时，可设置第一辅助部1021与限位孔1012边缘的最小距离大于或等于预设距离，以防止第一辅助部(碳油)1021与限位孔1012间距过小而易被磨损，或者在制作第一辅助部1021时因与限位孔1012间距过小而使得碳油制作到限位孔1012所在的区域，造成碳油的浪费。
可选地，辅助部仅设置为提供导电通路。
在原始系列打印设备的原始电路板中，两个端子之间不存在导电通路，但是在目标系列打印设备的原始电路板中，对应的两个端子之间存在导电通路，且对应的两个端子之间不存在电阻，因此，可设置辅助部仅设置为提供导电通路，不呈阻性，从而使得原始电路板添加辅助部后能够被目标系列的打印设备识别。辅助部无阻性并不意味着辅助部的电阻一定为零，而是辅助部的阻抗较小，辅助部两端的压降在打印设备对应的误差范围内，能够被打印设备所识别。
可选地，图3为本申请实施例提供的一种电路板的打印设备接触面的结构示意图，其可与图1中所示的电路板对应，结合图1至图3，原始电路板包括第一短路检测端子B1和第二短路检测端子B4，第一短路检测端子B1及第二短路检测端子B4均设置为与打印设备接触；辅助部102包括第二辅助部1022，第二辅助部1022与第一短路检测端子B1及第二短路检测端子B4连接，设置为提供第一短路检测端子B1与第二短路检测端子B4之间的导电通路。
结合图1至图3，原始电路板101上可包括第一短路检测端子B1、接地端子B2、电源端子B3、第二短路检测端子B4、第一传感器驱动端子B5、复位端子B6、时钟端子B7、数据端子B8及第二传感器驱动端子B9，其中，第一短路检测端子B1、接地端子B2、电源端子B3、第二短路检测端子B4位于上侧行，第一传感器驱动端子B5、复位端子B6、时钟端子B7、数据端子B8及第二传感器驱动端子B9位于下侧行，打印设备中包含设备侧电路401，设备侧电 路401可包括存储器控制电路4011、短路检测电路4012以及传感器驱动电路4013，分别通过对应的芯片侧端子(第一芯片侧端子C1、第二芯片侧端子C2、第三芯片侧端子C3、第四芯片侧端子C4、第五芯片侧端子C5、第六芯片侧端子C6、第七芯片侧端子C7、第八芯片侧端子C8及第九芯片侧端子C9)与第一短路检测端子B1、接地端子B2、电源端子B3、第二短路检测端子B4、第一传感器驱动端子B5、复位端子B6、时钟端子B7、数据端子B8及第二传感器驱动端子B9一一对应电连接，接地端子B2、电源端子B3、复位端子B6、时钟端子B7和数据端子B8连接至芯片201上，芯片201中可包括存储器，接地端子B2由打印设备上的第二芯片侧端子C2接地，存储器控制电路4011通过对应的端子向芯片201传输电源信号VDD、复位信号RST、时钟信号SCK以及数据信号SDA，短路检测电路4012通过第一短路检测端子B1及第二短路检测端子B4向芯片201输送短路检测信号CO1及CO2，传感器驱动电路4013通过第一传感器驱动端子B5、第二传感器驱动端子B9、第一传感器连接端子A1以及第二传感器连接端子A2向传感器传输驱动信号(SP与SN)，在原始系列打印设备的电路板中，第一短路检测端子B1与第二短路检测端子B4之间可能不存在导电通路，而目标系列的打印设备所对应的第一短路检测端子B1与第二短路检测端子B4之间需要有导电通路，在本实施例中，可通过设置第二辅助部1022，第二辅助部1022可提供第一短路检测端子B1与第二短路检测端子B2之间的导电通路，以使得原始电路板101能够应用到目标系列的打印设备中，完成了原始电路板101的跨代利用，极大的提高了原始电路板101的回收利用率，从而能够降低打印设备中电路板的成本，进而降低打印设备的成本。第二辅助部1022可以为碳油，对其形状不做限定，以使得原始电路板101添加第二辅助部1022后能够与目标系列打印设备兼容。
可选地，图4为本申请实施例提供的又一种电路板的打印设备接触面的结构示意图，参考图4，与图3中所示的电路板不同的是，图4中的原始电路板101上不包括设置为与打印设备中电路检测电路电连接的端子(对应于图3中的第一短路检测端子B1及第二短路检测端子B4)，辅助部102包括第三辅助部1023，第三辅助部1023包括设置为与短路检测电路电连接的接触部1123。
在原始系列打印设备的电路板中，可能不存在第一短路检测端子与第二短路检测端子，在本实施例中，而目标系列打印设备的设备侧电路包括短路检测电路(图2中所示)，若直接将原始系列打印设备的电路板(原始电路板)应用到目标系列的打印设备中，将会使得目标系列的打印设备因无法进行短路检测而产生异常，也即原始电路板与目标系列的打印设备不兼容。
参考图4，可将第三辅助部1023的接触部1123复用为端子，即利用第三辅助部1023上的接触部1123与打印设备中短路检测电路4012对应的端子接触， 从而使得原始电路板101能够应用到目标系列的打印设备中。
可选地，图5为本申请实施例提供的又一种电路板的打印设备接触面的结构示意图，参考图5，辅助部102包括凹槽，凹槽设置为阻断端子之间的导电通路。
原始电路板上两个端子之间可能存在导电通路，而目标系列打印设备所对应的两个端子之间不能够存在导电通路，此时可在两个端子之间设置凹槽，例如通过切割等方式形成切割槽(凹槽)，从而将所述的两个端子之间的导电通路断开，进而使得原始电路板添加辅助部后能够应用到目标系列的打印设备中。凹槽可为多个，从而保证不需要导电通路的两个或多个端子之间的导电通路能够断开。
可选地，继续参考图5，原始电路板101包括第一短路检测端子B1、接地端子B2和第二短路检测端子B4；第一短路检测端子B1、接地端子B2和第二短路检测端子B4均设置为与打印设备接触；第一短路检测端子B1设置为与芯片电连接；且原始电路板101中第一短路检测端子B1与接地端子B2之间存在导电通路；辅助部102包括凹槽1024，凹槽1024设置于第一短路检测端子B1与接地端子B2的导电通路上，设置为阻断第一短路检测端子B1与接地端子B2之间的导电通路。
原始电路板101上的第一短路检测端子B1与接地端子B2之间存在导电通路1013，从而使得原始电路板101能够应用到原始系列的打印设备中，然而目标系列的打印设备中，第一短路检测端子B1与接地端子B2之间若存在导电通路1013将会造成检测异常，进而使得原始电路板101无法直接应用到目标系列的打印设备中，本实施例中，可通过凹槽1024将导电通路1013断开，从而断开第一短路检测端子B1与接地端子B2之间的电气连接，进而使得原始电路板101能够应用到目标系列的打印设备中，完成原始电路板的再次利用。
图6为本申请实施例提供的一种电路器件的电路结构示意图，参考图6，电路器件包括本申请任意实施例提供的电路板和芯片201，芯片201中包括控制单元和存储器，芯片201的多个引脚与电路板的多个端子对应绑定。
芯片201可包括存储器，设置为存储传感器中的相关参数(如剩余墨水水平)，本实施例中以芯片201位于打印材料容器接触面为例进行说明，在其它一些实施方式中，芯片201也可位于打印设备接触面上，因其包括本申请任意实施例提供的电路板，因此也具有相同的效果，在此不再赘述。
可选地，存储器中存储有至少一个代系程序，控制单元设置为根据打印设备的类型执行对应的代系程序。
代系程序可用于与打印设备中的主控制器进行通信，以使得主控制器能够读取存储器中存储的信息，原始系列的打印设备对应电路板的存储器中只存储一代程序，当原始电路板应用到其他系列的打印设备中时，会存在程序不兼容的问题，进而使得打印设备无法对其进行识别，本实施例中可在存储器中存储至少一个代系程序，并且控制模块能够与打印设备中的主控制器进行通信，进而获取打印设备的型号，并根据打印设备的信号调用相应的代系程序，从而使得电路板能够兼容更多系列的打印设备，提高电路板的兼容性。
可选地，芯片的至少一个引脚定义与对应的端子的原始定义不同。
可根据打印设备的系列设置芯片的类型，如目标系列所需电路板上端子的端子定义与原始电路板上对应端子的端子定义不同时，可通过修改芯片的类型，修改芯片对应引脚的定义；如原始电路板上介于第一短路检测端子与电源端子之间的端子为接地端子，而目标系列的打印设备中，对应原始电路板上接地端子位置的端子不是设置为接地的端子，而是设置为传送时钟信号的端子，则可修改芯片的引脚定义，将芯片与原始电路板上对应接地端子的引脚修改为接收时钟信号的引脚，从而使得原始电路板与芯片均能够与目标系列的打印设备兼容。
本申请实施例还提供了一种打印材料容器组件，打印材料容器组件包括打印材料容器和本申请任意实施例提供的电路器件，打印材料容器与电路器件可拆卸连接。因其包括本申请任意实施例提供的电路器件，因此也具有相同的效果，在此不再赘述。
