Description

注墨器
本发明涉及一种对喷墨打印机用墨盒进行注墨的注墨器。本发明基于申请日为2012年06月29日、申请号为201210223586.9的中国发明专利申请，该申请的内容作为与本发明密切相关的参考文献引入本文。
喷墨打印机中的墨盒大多可以更换，作为耗材容器的墨盒通常具有盒体、墨腔、芯片、压力控制器等部件。墨腔内的墨一旦耗尽，整个墨盒即被丢弃，非常浪费且不环保。于是墨盒再生的注墨工具应运而生。现有的注墨工具可以给已耗尽墨的墨盒重新注墨，使得墨盒盒体、芯片等未损坏的部件可以继续发挥作用，最大程度地避免了资源浪费。
现有的注墨工具有大型的注墨机和小型的注墨器。注墨机体积庞大结构复杂，具有结构复杂的装夹机构，以对不同外形或尺寸的墨盒进行装夹，然后进行注墨。但是其庞大的体积和巨大的重量并不便携，不适合一般用户使用。小型的注墨器体积小，重量轻，非常适合办公、家庭或者个人使用，当然工厂也可以配备小型的注墨器，用于灵活性地生产墨盒，降低高额的设备购置费用。
现有注墨器的缺点是针对墨盒的具体尺寸进行设计的，对于外形大小不同的墨盒不具备兼容性。因此用户需要针对不同尺寸的墨盒购置不同的注墨器，为此用户的注墨器使用成本会大大增加，存储注墨器的空间也会倍增，注墨器寿命终结时也会产生较多的垃圾，不利于环保。
公告号为CN201415523Y的中国实用新型专利公开了名为注墨机的一种注墨器。该注墨器包括一底座、外壳、真空泵和计量泵。底座上设置有包括单片机的控制模块，该控制模块可实现对计量泵和真空泵的自动控制；外壳上设置有启动键合停止键。启动键接通后，注墨器可自动走完预设程序；紧急情况下按停止键，可终止真空泵和计量泵的工作。底座上还设置有可更换密封箱，该密封箱依据墨盒外形设置，可容纳不同的墨盒，其与注墨器的盖件配合实现墨盒定位及密封。盖件底面设置有墨盒检测装置，以检查墨盒是否已经安装，当检测到墨盒没有安装时，即便按下启动键，注墨器也不工作。
该设计的缺点是控制模块只能根据墨盒检测装置的信号判断墨盒是否安装，并不能识别墨盒类型。当用户把外形相似，如墨盒仅存在宽度上的差别，容量较小的墨盒错误地放进注墨器并注墨时，注墨器检测到墨盒已安装即会启动并注墨，此时便会导致墨水溢出而污染甚至损坏注墨器。用户把类似地对较大容量墨盒注墨时，则会导致墨盒未能注满墨水。换言之，该注墨器无法根据墨盒类型采取相应的注墨操作。例如，注墨器控制模块不能识别墨盒的外形大小，从而不能实现注墨时间或者注墨量的调整；另外，当预定颜色为红色的墨盒安装区内安装了黄色墨盒时，注墨器控制模块不能识别这一错误安装，会发生注墨混色。由此可见，该注墨器不能针对不同类型的墨盒实现全自动注墨。
本发明的主要目的在于提供一种适用于多种外形大小的墨盒，并可根据墨盒外形大小调整注墨量的注墨器。
本发明的另一目的在于提供一种防止注墨混色的注墨器。
为实现上述主要目的，本发明提供的注墨器包括外壳，外壳内设有墨盒安装区，还设有检测模块和根据检测模块的输出信号启动注墨程序的控制模块，检测模块包括设置在墨盒安装区附近并用于检测墨盒安装区内墨盒外形大小的检测部，控制模块内存储有与墨盒的外形大小对应的注墨程序。
进一步的方案是，检测部还能检测墨盒安装区内墨盒的颜色标记，控制模块内还存储有与墨盒安装区预定颜色相应的阈值，及禁注程序。
由该方案可见，当墨盒安装区内安装的墨盒的颜色标记的颜色与墨盒安装区的预定颜色不对应时，检测模块的输出信号将小于对应的阈值，控制模块进行比较后会启动禁注程序，禁止向该墨盒注墨，从而防止注墨混色。
另一进一步的方案是，检测部包括多个传感器，且各传感器安装在距所述墨盒安装区的底面不同的高度上。传感器为微动开关、光电传感器或其组合。当传感器被墨盒或仿真墨盒的前壁一侧上的外廓点触发时，其向单片机发送高电平信号，没有受到触发的传感器向单片机发送低电平信号。
微动开关和光电传感器在墨盒触发和信号输出方面具有较高可靠性、灵敏度和耐用度；体积细小，设置在相对于墨盒安装区的底面的不同的高度处，有效利用墨盒零散空间，有利于注墨器实现小型化设计，便于包装、存储及运输。单片机根据传感器输出的电平信号，启动存储器中与墨盒外形大小对应的注墨程序，自动为墨盒注入适量的墨水，从而对外形大小不同的墨盒实现自动化注墨，提升注墨效率。
本发明能根据墨盒外形即容墨量的大小调整注墨量。

本发明所述的墨盒均指待灌墨的墨盒。下面结合附图，对本发明的具体实施方式作详细说明。
注墨器整体结构
参见1、图2及图4，注墨器1100的外壳1101包括上壳1140、下壳1150、可开闭的上盖1160和可开闭的下盖1170。在上壳1140上布置有一个供用户开启注墨器1100的启动按钮1911以及多个能显示注墨器1100运行状况的LED灯1920。在外壳1101中设置了一个装置底座1102，装置底座1102包括墨盒座1120、墨水容器座1600。
墨盒座1120上设有底槽1130、压盖1200、支承轴1122以及硅胶垫1131。其中，压盖1200可以绕支承轴1122转动；硅胶垫1131用于墨盒供墨口1111及连通口1123的密封对接。注墨器可以给高度尺寸不一样的墨盒1110注墨，当给高度较小的墨盒1110注墨时，只需在墨盒和压盖之间垫上适配器1300即可。
墨水容器座1600中放置有墨水容器1500。墨水容器1500上设置一对用于安装定位的凹槽1550，防止其自身在负压下变形的加强部1560，出墨口1520以及气孔1530。出墨口1520和气孔1530中各布置有一个密封件1540。密封件1540优选为自闭密封件。当墨水容器1500被安装到墨水容器座1600时，出墨口1520与转接头1620密封对接。
墨水容器座1600上还设置有通气部1630。通气部1630中设置有密封件1633。优选的，本发明的注墨器1100配置有废墨仓1400。废墨仓1400包括废墨仓入口1410，废墨仓出口1420以及海绵1430。其中，海绵1430可以吸收灌墨过程中产生的墨水泡，避免墨水逃离墨水容器1500，进入到其它部件。废墨仓入口1410与墨水容器1500的气孔1530密封对接，废墨仓出口1420与通气部1630密封对接。
注墨器1100内还配置有泵1720，泄压阀（图中未示出），第一管道（图中未示出）和第二管道（图中未示出）。第一管道的第一端与泵1720密封对接，第二端与通气部1630密封对接；第二管道的第一端与连通口1123密封对接，第二端与转接头1620密封对接；泄压阀通过三通安装在第一管道上。
注墨器适用的墨盒
墨盒1110按墨水颜色分为容纳黑色墨水的墨盒1110B和容纳彩色墨水的墨盒1110C（参见图10），按墨水容量分为高容量的墨盒1110H和低容量的墨盒1110L（参见图20和图21）。
高容量黑色墨盒1110BH和高容量彩色墨盒1110CH在墨盒座1120的安装实例参见图10，低容量黑色墨盒1110BL和低容量彩色墨盒1110CL在墨盒座1120的安装实例参见图13。
参看图20和图21，高低容量墨盒1110H和低容量的墨盒1110L的主要差别在于前者高度H比后者的高度h大。
如图20所示，墨盒1110具有设置在其底壁1116的供墨口1111，设置在其顶壁1113的大气口1112以及设置在负压腔1119a内的负压构件1117。通常负压构件1117不限于海绵，也可以是阀等其它可以保持墨盒负压的构件或结构。墨水腔1119b用于存储墨水，负压腔1119b对应的顶壁1113上设有注墨口（图中未示出），该注墨口平时处于关闭状态。
如图22所示，墨盒1110具有四侧壁1114和用于定位的前凸1118a和杆件1118b；其中，前凸1118a所在的侧壁1114充当墨盒1110的前壁1115。通过前凸1118a和杆件1118b与图4中所示的锁孔1124和锁扣1125配合即可把墨盒1110安装定位在底槽1130。
根据图10和图13所示的墨盒1110的安装实例可知，注墨器1100的墨盒座1120可以同时安装多个颜色或容量大小不同的墨盒1110。墨盒座1120中安装有一个盛装黑色墨水的墨盒1110B和五个盛装彩色墨水的墨盒1110C。其中五个墨盒1110C的墨水颜色分别是照片黑、红色、黄色、蓝色和灰色。墨盒座1120上贴有对应各种墨水颜色的带文字标识的颜色标签（图中未示出），以便各色墨盒1110被安装到相应的底槽1130中时加以识别。颜色标签上的颜色即底槽1130的预定颜色。
以下对注墨器1100的一些部件作详细说明。
墨水容器座
图5所示的是注墨器1100的下壳1150的俯视图。下壳1150包括整体呈长方形的凸起框1152和4个螺丝孔1151。
图6是注墨器1100的墨水容器座1600的前视图，图7是墨水容器座1600的立体图，图8是墨水容器座1600沿图6所示B-B线的剖视立体图。
如图8所示，墨水容器座1600内设多个呈长方体状的槽1610。槽1610由底壁1611，上壁1612，下壁1613及一对侧壁1614围成，其中相邻的槽1610共用一个侧壁1614。优选的，墨水容器座1600通过一体注塑成型。当然墨水容器座1600也可以由多个具有独立槽体的单元组装而成；每个槽1610也可以拥有各自独立的侧壁1614。
优选的，作为第一接头的转接头1620设置在槽1610在重力方向上的底部，以利于放置在槽1610中的墨水容器1500排空墨水。
转接头1620为与底壁1611一体成型的管体，其第一端1621可与墨水容器1500的出墨口1520密封对接，第二端1622与第二管道第二端密封对接。
由图4和图8可知，墨水容器座1600的上壁1612上设置有凸起1615，下壁1613上设置有凸起1616，凸起1615和凸起1616分别与墨水容器1500上的一对凹槽1550卡合以定位墨水容器1500。优选的，凸起1615和凸起1616与墨水容器座1600一体成型，凸起1615和凸起1616可以分别随上壁1612及下壁1613的挠性变形而移动，以便于墨水容器的装卸，简化墨水容器座1600的结构。
如图7所示，墨水容器座1600底部设置有下连接部1640，下连接部包括四个螺丝孔1641和四个定位璧1642。四个螺丝孔1641分别与下壳1150上的四个螺丝孔1151对正，以便通过螺丝把墨水容器座1600紧固在下壳1150上；四个定位壁1642分别与下壳1150的凸起框1152的四个内壁面贴合，以定位墨水容器座1600。
墨水容器座1600的槽1610可以水平地设置，也可以相对水平面倾斜地设置。槽1610相对水平面倾斜的角度范围优选的为10至45度。图4中槽1610的下壁相对水平面倾斜的角度为12度，倾斜设置的方案便于装卸墨水容器，和充分利用注墨器1100的内部空间，减少注墨器1100水平方向尺寸，进而减少注墨器1100在水平面上的投影面积，从而减少桌面占用面积。
注墨器1100的第一管道的第二端可以直接与墨水容器气孔密封对接。但这样连接存在墨水泡通过第一管道进入泵1720的风险。因此，优选的，在第一管道第二端与气孔1530之间串接废墨仓1400，以过滤墨水泡（参见图4）。
参看图4，作为第二接头的通气部1630成型在在墨水容器1600的座顶部，以便于废墨仓1400与其连接。通气部1630的第一端1631与泵1720密封对接，第二端1632内设密封件1633并可与废墨仓1400的废墨仓出口1420密封对接。废墨仓入口1410设置在废墨仓1400一个侧面的一端上，并可与墨水容器1500的气孔1530密封对接；废墨仓出口1420设置在废墨仓入口1410所在的侧面的另一端上，并可与通气部1630的第二端1632密封对接。优选的，废墨仓出口1420向废墨仓1400的内部延伸，以进一步防止通过海绵1430的墨水流出废墨仓。当然，除了使用海绵过滤墨水泡和墨水飞沫外，还可以替代性的采用侧面朝向废墨仓入口1410的一个、两个或更多的肋来戳破墨水泡和消减墨水飞沫。墨水容器座1600外侧设置有带螺孔的定位台1660。通过U型压块及螺钉（图中未示出）与定位台1660的配合可以对注墨器1100中的所有管道进行收纳整理并固定，防止管道自由摆动而出现管道松脱的危险。当然也可以通过成型或装配在墨水容器座或者壳体内其它部位上的管卡对各管道进行收容整理和固定。
由图3及图4可知，墨水容器座1600设置7个槽1610，每个槽1610可以容纳一个独立的墨水容器1500。其中两个墨水容器1500存储黑色墨水，其余五个墨水容器1500存储与墨盒1110C对应的五种彩色墨水。该设计的好处是给高容量黑色墨盒1110BH和低容量彩色墨盒1110CL一起灌墨时，每个墨水容器1500的墨水可以基本同时耗尽，有利于统一更换墨水容器1500，避免频繁出现低墨量警告及更换墨水容器1500，保证较高的灌墨效率。注墨器1100可以实现对多个不同颜色不同容量的墨盒1110同时注墨，因此注墨效率非常高。另一方面，可能出于某些特别原因，某些特定颜色的墨水使用量特别大，因此注墨时墨水容器1500中某些特定颜色的墨水被消耗得较快。采用独立的槽1610安装独立的墨水容器1500允许方便地更换某相应颜色的墨水容器1500，灵活地满足灌墨打印需求。
[0039] 当某一墨水容器1500中的墨水耗尽时，只需抽出相应的墨水容器1500，插入新的具有相应颜色墨水的墨水容器1500即可，各个墨水容器1500的更换互不干涉，互不影响。
[0040] 如果想对墨水容器1500进行加墨的话，可先把墨水容器1500从槽1610中取出，在远离注墨器的地方，在出墨口1520或气孔1530的任一密封件1540处，用针筒或者弹簧瓶（图中未示出）进行灌注。这样只需对墨水容器1500进行一次灌注，注墨器1100即可对墨盒1110进行多次灌注，同样可以简化注墨操作，降低漏墨及污染的风险。
压盖及墨盒座
参看图9至图11，压盖1200、底槽1130及墨盒1110的个数一一对应，因此每个墨盒1110的装卸互不干扰。
压盖1200一端设置铰接孔1201，墨盒座1120上设置有支承轴1122。压盖1200通过铰接孔1201与支承轴1122可旋转连接，铰接孔1201与支承轴1122之间安装了橡胶轴承1216。压盖1200另一端设置具有弹性的手柄1210，手柄1210具有扣合部1211、操作部1212和根部1213；墨盒座1120上与支承轴1122相对的另一侧设置有扣位1121。手柄1210具有弹性。推动操作部1212时，扣合部1211脱离扣位1121，压盖1200在推力作用下绕着支承轴1122被顺势掀开；当绕着支承轴1122向下压压盖1200时，手柄1210受到扣位1121的压迫而向远离扣位1121方向移动，当扣合部1211越过扣位1121时，扣合部1211在手柄1210自身弹性回复力作用下向扣位1121靠近并与扣位1121扣合。压盖1200背向墨盒座1120一侧设有上凸1214，还可以通过捏着操作部1212和上凸1214来迫使扣合部1211脱离扣位1121，从而开启压盖。压盖1200背向墨盒座1120的一侧上设置了与操作部1212相对的止动凸1215，以防止手柄1210因过度变形而损坏。压盖1200面向墨盒1110一侧设置槽1203，槽1203内嵌有作为密封件的橡胶垫1204，橡胶垫1204的销轴1206插在压盖1200的卡孔1205中。当压盖1210与扣位1121扣合时，橡胶垫1204压紧并密封墨盒的大气口1112，此时墨盒在压盖所施加的压力下，被更加稳固的固定在底槽1130上，出墨口1111的密封效果得到进一步提高。
注墨过程
泵1720经第一管道、通气部1630及废墨仓1400与墨水容器1500在气孔1530处相对外部大气密封地连通；墨水容器1500的出墨口1520经转接头1620、第二管道及连通口1123与墨盒1110在供墨口1111处相对外部大气密封地连通；墨盒1110的气孔1112可预先通过焊膜密封或者利用压盖1200上的橡胶垫1204或适配器1300上的橡胶垫1310进行密封。
注墨时，泵1720先对墨水容器1500及墨盒1100抽负压，此时第一管道上的泄压阀关闭；当墨盒内部负压达到预定值时，泵1720停止抽负压；然后泄压阀打开，使得第一管道经过泄压阀与大气相通；由于墨盒内部压力低于大气压，因此，墨水容器1500中的墨水在大气压力作用下压入墨盒，直至压力平衡。
上述抽负压过程中，墨盒1110里的气体经过出墨口1520进入墨水容器1500，气体在墨水容器1500内的墨水中形成气泡并不断上升至墨水液面，有些气泡在上升至液面时破裂形成墨水飞沫，而没有破裂的气泡形成墨水泡并不断累积，墨水泡和墨水飞沫会在泵1720的抽负压作用下进入气孔1530并向泵1720的方向移动。废墨仓1400可以有效消除墨水泡和墨水飞沫，防止其经过第一管道进入泵1720。
当然，注墨器1100也可以采用正压注墨。此时，墨盒1110上的大气口1112仍然被密封，但注墨口打开。泵1720直接向墨水容器加正压即可。由于正压注墨不会产生墨水泡和墨水飞沫因此并不需要废墨仓1400，通气部1630的第二端1632可以与墨水容器1500的气孔1530直接通过U形管密封地连通。还可以把第一管道的第二端与墨水容器1500的气孔1530直接密封对接。
墨盒检测
图25是本发明第一实施方式的墨盒检测示意图。其中，图25b至图25d中省略了墨盒座1120及其附属结构。
参看图25，墨盒座1120上设置有作为墨盒安装区并用于放置墨盒1110的底槽1130。其中，底槽1130的底面1132即墨盒安装区的底面。检测模块1930的检测部包括分别作为第一传感器和第二传感器的上微动开关1933和下微动开关1934。其中，上微动开关1933设置在上电路板1931，下微动开关1934设置在下电路板1932。上微动开关1933和下微动开关1934设置在底槽1130附近，以确保墨盒1110装入底槽1130时处于上微动开关1933和下微动开关1934的有效检测范围内。控制模块（图中未示出）包括一设置在下电路板上1931上的单片机（图中未示出）。该单片机分别与上微动开关1933和下微动开关1934电连接。
上微动开关1933和下微动开关1934优选分别设置在距底面1132的第一高度和第二高度上，并且上下对齐。
硅胶垫1131为设置在连通口1123处的自闭密封件， 当底槽1130安装墨盒1110时，出墨口1111将解除硅胶垫1131的自闭，并使得出墨口1111与连通口1123密封地连通；当底槽1130中无墨盒1110时，硅胶垫1131恢复自闭状态，密封连通口1123。为了进一步的保证不安装墨盒1110时连通口1123的密封性，在底槽1130中安装仿真墨盒1740。其中，仿真墨盒1740与墨盒1110的出墨口1111对应位置的管体1741是封闭的（参见图27）。具有自闭功能的硅胶垫1131，在不安装墨盒1110和仿真墨盒1740的情况下，既可防止第二管道中的墨水被外部大气氧化又可防止飘尘进入第二管道。当然，也可以使用带密封垫圈的机械阀代替硅胶垫1131。不安装墨盒1110时，机械阀的阀门关闭；安装墨盒1110时，出墨口1111通过密封垫圈与机械阀密封对接，并推压机械阀的控制杆打开其阀门，以使得出墨口1111与连通口1123相对外部大气密封连接。
对比图20和图27可知，仿真墨盒1740的外部形状结构与大容量墨盒1110H基本一致。特别的，二者在底槽1130的底面1132法向上的高度相同，装入底槽1130中后，均可被压盖1200直接进一步地压紧。
如图25c所示，仿真墨盒1740在其前壁1745和底壁1746拐角处设置有缺口1747，装入底槽1130中后，缺口1747正好避开下微动开关1934，因此，不会触压下微动开关1934。
当上微动开关1933或下微动开关1934被触压时，则被触发，并向单片机输出高电平信号；若未被触压，则不会被触发，并向单片机输出低电平信号。高电平信号用“1”表示，低电平信号用“0”表示。
当底槽1130中安装高容量墨盒1110H时，上微动开关1933和下微动开关1934均受到高容量墨盒1110H的前壁1115上的外廓点触压，上微动开关1933和下微动开关1934一起输出的电平信号为“11”。
当底槽1130中安装低容量墨盒1110L时，只有下微动开关1934被低容量墨盒1110H的前壁1115上的外廓点触压，上微动开关1933和下微动开关1934一起输出的电平信号为“01”。
当底槽1130中安装仿真墨盒1740时，只有上微动开关1933被仿真墨盒1740的前壁1745上的外廓点触压，上微动开关1933和下微动开关1934一起输出的电平信号为“10”。
当底槽1130空置时，上微动开关1933和下微动开关1934均没有受到触压，它们一起输出的电平信号为“00”。
上微动开关1933和下微动开关1934所输出的电平信号组合共有上述4种情况：“11”、“01”、“10”和“00”，该4种情况分别对应表示4种检测结果：“底槽1130已安装高容量墨盒1110H”，“底槽1130已安装低容量墨盒1110L”，“底槽1130已安装仿真墨盒1740”和“底槽1130空置”。单片机内存储有与“11”对应的第一注墨量注墨程序，与“01”对应的第二注墨量注墨程序，与“10”对应的零注墨量注墨程序，以及与“00”对应的禁注程序。单片机根据上微动开关1933和下微动开关1934输出电平信号的组合情况，即可识别墨盒安装情况，启动对应的注墨程序或禁注程序。从而实现根据墨盒高度大小调整注墨量，对不同高度的墨盒进行自动化注墨，提高注墨效率，又可防止注墨器1100给墨盒1110注入不适量的墨水。其中，当注墨器执行负压注墨时，第一注墨量注墨程序控制泵执行第一预定时间的抽负压操作；第二注墨量注墨程序控制泵执行第二预定时间的抽负压操作；零注墨量注墨程序控制泵不执行操作；禁注程序控制泵不执行操作且通过指示灯和扬声器发出声光报警信号。当注墨器执行正压注墨时，第一注墨量注墨程序控制泵执行第一预定时间的加压操作；第二注墨量注墨程序控制泵执行第二预定时间的加压操作；零注墨量注墨程序控制泵不执行操作；禁注程序控制泵不执行操作且通过指示灯和扬声器发出声光报警信号。
注墨器中微动开关的另一布置方式如下。
微动开关的布置方式还可以如图4示，该实施方式与前述实施方式的主要区别在于微动开关的布置位置，上微动开关1933和下微动开关1934分别设置在距底面1132的第一高度处和第二高度处，但上下错位。其中，上微动开关1933与下微动开关1934相比，安装在相对远离底槽1130中心的位置。该布置方式可以更充地分利用注墨器1100中的空间，减少注墨器1100的体积。
对比图11及图14可知，高容量的墨盒1110H可以直接安装在底槽1130中，并被合上的压盖1200压住其具有大气口1112的顶壁1113，从而实现墨盒1110H的密封和进一步的夹紧。但是，低容量墨盒1110L的高度比高容量墨盒1110H的要小，压盖1200不能直接压住低容量的墨盒1110L具有大气口1112的顶壁1113。
如图14所示，适配器1300垫在墨盒1110L和压盖1200之间。即，压盖1200可通过适配器1300压紧墨盒1110L。
由图15至图19可知，适配器1300为一长方体状部件，其包括一顶壁1301，四侧壁1302和从顶壁1301向远离顶壁1301方向延伸的肋1303，肋1303的末端构成一底面1304。在垂直顶壁1301的方向上，侧壁1302具有较肋1303长的端部1302a；侧壁1302上具有缺口1302b，侧壁1302上两缺口1302b之间的位置及靠近凸台1320的侧壁1302上设置有加强筋1306。适配器1300上设置有垂直于顶壁1301的连接孔1305和橡胶垫1310。把橡胶垫1310上的连接销1315插入连接孔1305中可定位橡胶垫，优选的，连接销1315和连接孔1305之间为紧配合。在垂直于顶壁1301方向上，橡胶垫1310的工作面1311距顶壁1301的距离较底面1304距顶壁1301的距离大，较端部1302a距顶壁1301的距离小。
把适配器1300套在墨盒1110L上时，橡胶垫1310的工作面1311贴着墨盒1110L顶壁并正对着大气口1111，四个侧壁1302上的加强筋1306分别贴着墨盒1110L上的四个对应的墨盒侧壁1114。优选的，加强筋1306与墨盒1110L的侧壁紧配合，适配器1300侧壁1302上的缺口1302b可以增大侧壁1302及端部1302a的弹性，防止适配器1300被墨盒1110L挤坏。
优选的，可以先把适配器1300装在墨盒1110L上，然后一并装进底槽1130中，最后合上压盖1200。此时，压盖1200上的橡胶垫1204与适配器1300顶壁1301接触并压紧适配器1300。适配器1300在压盖1200压力下，其橡胶垫1310的工作面1311紧压着墨盒1110L的顶壁1113，并密封大气口1112。由于适配器1300的端部1302a及加强筋1306实现了适配器1300与墨盒1110L的稳定连接，所以墨盒1110L能够有效的被压紧和密封。另外，适配器1300位于墨盒1110L的上方，即便出墨口1111在注墨时发生漏墨，适配器1300也不会被污染。
图28中低容量仿真墨盒2740L与低容量墨盒1110L的外形基本一致，二者具有相同的高度，均可安装适配器1300。其中，适配器1300的加强筋1306可与图30中所示的低容量仿真墨盒2740L的侧壁1744紧配合；适配器1300的橡胶垫1310的工作面1311可与低容量仿真墨盒2740L的顶壁1743贴合。
图29是第二实施方式中的高容量仿真墨盒2740H的侧面局部剖视图。图中高容量仿真墨盒2740H与高容量墨盒1110H的外形基本一致，二者具有相同的高度，前者的前壁1745上还设置有悬凸2744。
低容量仿真墨盒2740L和高容量仿真墨盒2740H底壁1746上的管体1741被密封;低容量仿真墨盒2740L和高容量仿真墨盒2740H装入底槽1130后，二者的缺口1747均避开下微动开关1934,而不会触压下微动开关1934。
由图26a可知，当底槽1130中安装高容量墨盒1110H时，只有下微动开关1934被高容量墨盒1110H的前壁1115上的外廓点触压而受到触发，上微动开关1933和下微动开关1934一起输出给单片机的电平信号为“01”。
由图26b可知，当底槽1130中安装低容量墨盒1110L和适配器1300时，上微动开关1933和下微动开关1934分别受到适配器1300作为外廓点的凸台1320前端及低容量墨盒1110L的前壁1115上的外廓点触压，上微动开关1933和下微动开关1934一起输出的电平信号为“11”。
由图26c可知，当底槽1130中安装低容量仿真墨盒2740L和适配器1300时，只有上微动开关1933被适配器1300作为外廓点的凸台1320前端触压，上微动开关1933和下微动开关1934一起输出的电平信号为“10”。
当底槽1130空置时，上微动开关1933和下微动开关1934均没有受到触压，它们一起输出的电平信号为“00”。
上述上微动开关1933和下微动开关1934所输出的电平信号组合共有4种情况：“01”、“11”、“10”和“00”，该4种情况分别对应表示4种检测结果：“底槽1130已安装高容量墨盒1110H”，“底槽1130已安装低容量墨盒1110L”，“底槽1130已安装仿真墨盒2740L”和“底槽1130空置”。单片机内存储有与“01”对应的第一注墨量注墨程序，与“11”对应的第二注墨量注墨程序，与“10”对应的零注墨量注墨程序，以及与“00”对应的禁注程序。单片机根据上微动开关1933和下微动开关1934输出的电平信号的组合情况，即可识别墨盒安装情况，启动对应的注墨程序或禁注程序。
参见图26e，作为图26c中低容量仿真墨盒2740L和适配器1300配合使用的替换手段，只需直接在底槽1130上安装高容量仿真墨盒2740H即可。此时，只有上微动开关1933被作为外廓点的悬凸2744前端触压，上微动开关1933和下微动开关1934一起输出的电平信号为“10”。使用高容量仿真墨盒2740H无需安装适配器1300，因此操作效率相对较高。
以上两实施方式中，墨盒、适配器和仿真墨盒的外廓点均位于墨盒或仿真墨盒前壁一侧。
以上实施方式中，注墨程序和禁注程序存储在单片机内。作为一种替代手段，注墨程序和禁注程序还可以存储在控制模块中与单片机电连接的存储器内。该存储器可以是ROM、EEPROM或FRAM。
参看图23,上电路板1931上固定有6个上微动开关1933，下电路板上固定有6个下微动开关1934。电路板1931和电路板1932可以通过螺钉或卡扣等方式固定在墨盒座上。每个底槽对应一组第二实施方式中的上微动开关1933和下微动开关1934。因此，检测模块可以同时对6个底槽进行检测，并识别其中墨盒的高度及判断是否安装墨盒或仿真墨盒。因此，注墨器具有非常高的检测效率，节省用户注墨时间。
在另一实施方式中，还可以在每个底槽1130与墨盒前壁1115对应的槽壁上，沿底面1132平行的方向设置两个微动开关（左微动开关和右微动开关，图中均未示出）。当槽1130中安装较宽的墨盒时，两个微动开关因同时被墨盒的外廓点触压，两微动开关输出“11”信号；当底槽1130安装较窄的墨盒时，只有左微动开关被触压，两微动开关输出“10”信号，当底槽1130空置时，两微动开关均没有被触压，输出“00”信号。单片机根据微动开关输出的电平信号的组合情况即可识别底槽1130中墨盒的宽窄或空置情况，进而启动存储器中对应的注墨程序或禁注程序。类似的，在与墨盒前壁相邻的侧壁相对的底槽的侧壁上沿底槽底面平行的方向上布置两个微动开关，单片机根据该两微动开关输出的信号的组合情况即可识别底槽1130中墨盒的长短或空置情况，进而启动存储器中对应的注墨程序或禁注程序。
以上各实施方式中，每个底槽对应两个微动开关。但本发明不局限于此，每个底槽1130在其底面1132垂直或平行的方向上的不同位置处，可以设置3个甚至更多的微动开关，以检测3种或更多种高度、宽度或长度的墨盒，对应的，墨盒的顶壁、侧壁、前壁或底壁外表面上的点均可作为墨盒的外廓点；仿真墨盒的顶壁、侧壁、前壁或底壁外表面上的点都可作为仿真墨盒的外廓点，以与相应的微动开关触压。
当然，也可以在每个底槽1130与墨盒前壁1115对应的槽壁上，L形地布置三个微动开关，以同时检测高度和宽度不同的墨盒。
以上所有实施方式中，受触发的微动开关向单片机输出高电平信号，不受触发的微动开关向单片机输出低电平信号。但本发明不局限于此，也可以相反，受触发的微动开关向单片机输出低电平信号，不受触发的微动开关向单片机输出低高平信号。
电平信号可以是电流电平信号，也可以是电压电平信号或功率电平信号。
以上，检测部是微动开关，也可以采用电容式接近开关，还可以是应变式力传感器，电容压力传感器或压电式测力传感器。这些开关或传感器的布置方式与前述一样。
此外，参见图31，检测部还可以是具有主动光源的光电传感器，其发射部3933a、3934a和接收部1933b、3934b分别位于底槽1130上的墨盒1110两侧，以使得发射部不被墨盒遮挡时，接收部可以从发射部获得足够的光强。
检测部输出给单片机的信号不限于仅有高低电平之分的开关量。当检测部为布置在压盖1200靠近底槽1130一侧，并正对墨盒的顶壁1113的超声波物位传感器时，超声波物位传感器检测墨盒的顶壁1113或底槽的底面1132到其探头之间的距离，并向单片机输出表示该距离的信号，单片机根据该信号即可启动存储器中对应的注墨程序或禁注程序。当检测部为超声波物位传感器时，注墨器可省去适配器；超声波物位传感器宜安装在底槽1130附近，以使得墨盒顶壁1113和底槽底面1132位于其有效检测范围内。
检测部还可以是CCD或CMOS固态图像传感器。当CCD或CMOS固态图像传感器与上述超声波物位传感器采用相同的布置方式时，CCD或CMOS固态图像传感器可以采集墨盒的顶壁外表面的图像信息，并向单片机输出表示该图像信息的信号，单片机根据该信号即可读取墨盒的宽度、长度、顶壁外表面或贴在顶壁上的颜色标签中色块的颜色，进而启动存储器中对应的注墨程序。其中，顶壁外表面的颜色或颜色标签上的色块充当墨盒的颜色标记；存储器中存储有与底槽1130预定颜色相应的阈值。当墨盒的颜色标记的颜色与底槽1130的预定颜色不对应时，CCD或CMOS固态图像传感器输出关于颜色的信号将与该底槽1130预定颜色对应的阈值不符，单片机进行比较后会启动禁注程序，以防止注墨混色。当读取到表示底槽1130底面1132图像信息的信号时，表示底槽1130中没有墨盒，单片机也会启动禁注程序，以防止注空漏墨。当CCD或CMOS固态图像传感器输出关于颜色的信号与该底槽1130预定颜色对应的阈值相符时，单片机才根据墨盒的宽度和/或长度启动存储器中对应注墨程序。显然，CCD或CMOS固态图像传感器不限于设置在墨盒的顶壁上方，还可以设置在该墨盒的前壁前方；也可以在该墨盒的顶壁上方和前壁前方分别设置CCD或CMOS固态图像传感器，以检测更多的关于该墨盒外形的信息。
当然，检测部还可以是读取或读写RFID标签的射频信号接收天线。射频信号接收天线设置在底槽1130附近，以保证其能有效的读取或读写墨盒上的RFID标签。墨盒上的RFID标签内存储有关于墨盒的型号、容量、颜色、形状大小和生产日期等信息，其中的颜色信息充当墨盒的颜色标记。注墨器通电后，射频信号接收天线读取RFID标签内的颜色标记、外形大小信息，然后把这些信息输出给单片机。当读取的颜色标记和存储器中存储的预定颜色相应的阈值相符时，单片机根据墨盒外形大小信息启动存储器中对应的注墨程序；当不相符时，单片机启动禁注程序。
检测部还可改进如下：检测部增设色敏传感器，其与上述超声波物位传感器采用相同的布置方式，以检测墨盒顶壁的颜色标记。当底槽1130装入颜色标记与其预定颜色不一致的墨盒或空置时，色敏传感器输出关于颜色的信号与预定颜色对应的阈值不符，单片机进行比较后会启动禁注程序；当与对应的阈值相符时，单片机再根据外形大小信息启动存储器中对应注墨程序。
单片机可以是SCM，也可以是MCU。
本发明注墨器的检测模块包括了设置在墨盒安装区附近并用于检测墨盒外形大小的检测部，控制模块将根据检测模块的输出信号启动与墨盒的外形大小对应的注墨程序，从而实现根据墨盒外形大小调整注墨量的目的。
