Description

墨盒及打印设备 技术领域
本申请涉及打印机技术领域，尤其涉及一种墨盒及打印设备。
背景技术
墨盒是指喷墨打印机中用来存储打印墨水的部件，是喷墨打印机中的重要组成部分，它的好坏以及安装的正确性与否直接影响打印机的打印效果。
图1为现有技术中墨盒与设置在打印机上的安装部的匹配示意图，参考图1所示，安装部100包括定位孔110、安装腔120、供墨部130、打印机侧端子部140。墨盒200包括把手210、卡合部211、墨腔220、出墨口230、芯片240，其中，卡合部211与定位孔110相匹配。当墨盒200安装至安装部100上时，卡合部211卡合于定位孔110中，可以将墨盒200固定到安装部100的安装腔120内，防止墨盒200脱离安装部100。与此同时，芯片240与打印机侧端子部140形成电连接，出墨口230与供墨部130相匹配，将墨腔220内的墨水供给打印机的打印头，为打印工作提供墨水。
但是，这种安装方式会有一定的弊端，图2为现有技术中墨盒安装偏移示意图，参考图2所示，卡合部211卡合于定位孔110中，虽然能够在Z轴方向上防止墨盒200脱离安装部100，但是并不能防止墨盒200在Y轴方向上的偏移，具体的，墨盒200与安装部100的正确安装位置为位置O，但是，墨盒200可能会在Y轴方向上发生偏移，会到达右偏移位置A或者左偏移位置B处，从而产生芯片240无法与打印机侧端子部140形成电连接或者打印机无法识别墨盒200的芯片240的情况。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
喷墨打印机基本的工作原理是先产生小墨滴，再利用喷墨头把细小的墨滴导引至设定的位置上，墨滴越小，打印的图片就越清晰。基本原理看起来很简单，但操作起来就没那么简单，正如微积分原理一样并不复杂，但是如何运用就复杂了。
喷墨打印机包含墨盒，墨盒是喷墨打印机中用来存储打印墨水的部件，是喷墨打印机中重要的组成部分，它的好坏以及安装的正确性与否直接影响打印机的打印效果，但是，在现有技术中，经常会出现墨盒安装偏移的情况，使得墨盒上的芯片无法与打印机侧端子部正常电连接甚至出现打印 机无法识别墨盒上芯片的情况。
有鉴于此，本申请提供的墨盒以及打印设备，一方面可防止墨盒在竖直方向上脱离打印设备的安装部，结构简单，安装操作容易，能将墨盒稳固的固定在打印设备的安装部中，另一方面，可防止墨盒特别是芯片在芯片所在侧壁的延伸方向上的偏移，并且，避免了因定位凸台远离芯片造成的芯片偏移误差大的情况。
实施例一：
图3为本申请实施例提供的一种打印设备的安装部结构示意图，图4为本申请实施例提供的一种打印设备的安装部部分剖视图。
参考图3和图4所示，本申请实施例提供的一种打印设备，比如，打印机具有可以安装并固定墨盒的安装部30。安装部30可以容纳一个或者多个墨盒，如果安装部30容纳多个墨盒时，可以是不同颜色的墨盒。如图3所示，安装部30可以容纳4个墨盒，可以是相同颜色的一种墨盒(例如：黑色)，也可以是四种不同颜色的墨盒(例如：黑色、红色、黄色、蓝色)。安装部30是具有开口30b的大体呈长方体形状的一组件。安装部30具有底壁30a、开口30b、第一侧壁30c、第二侧壁30d、第三侧壁30e、第四侧壁30f。安装部30具有安装腔320，安装部30包括：至少两个安装板35，至少一个打印机侧端子部以及供墨部330。2个安装板35之间设置了打印机侧端子部。底壁30a与开口30b相对设置，第一侧壁30c与第二侧壁30d相对设置，第三侧壁30e与第四侧壁30f相对设置。底壁30a、第一侧壁30c、第二侧壁30d、第三侧壁30e、第四侧壁30f围成容纳墨盒40的安装腔320。供墨部330设置在安装腔320的底壁30a上，打印机侧端子部设置在第一侧壁30c上。建立三维直角坐标系XYZ坐标系。X轴、Y轴、Z轴相互垂直。底壁30a指向开口30b的方向为+Z轴方向，第二侧壁30d指向第一侧壁30c的方向为+X轴方向，第三侧壁30e指向的第四侧壁30f方向为+Y轴方向。示例性的，第一侧壁30c上设置有多个打印机侧端子部、多个安装板35。多个安装板35用于将多个打印机侧端子部固定在第一侧壁30c上，且将多个打印机侧端子部分隔开，避免两两之间发生短路情况。
示例性的，如图3和图4所示，安装部30可以安装4个墨盒40，具 有4个安装位，分别为第一安装位31、第二安装位32、第三安装位33以及第四安装位34。每个安装位都会有一个打印机侧端子部，分别为第一打印机侧端子部3601、第二打印机侧端子部3602、第三打印机侧端子部3603以及第四打印机侧端子部3604，打印机侧端子部之间有安装板35间隔。第一安装位31的第一打印机侧端子部3601安装在安装板35之间，且两边安装板35上分别具有第一对置面311和第二对置面312。第一对置面311位于第一打印机侧端子部3601的-Y轴方向侧，第二对置面312位于第一打印机侧端子部3601的+Y轴方向侧。第二安装位32的第二打印机侧端子部3602安装在安装板35之间，且两边安装板35上分别具有第三对置面321和第四对置面322。第三对置面321位于第二打印机侧端子部3602的-Y轴方向侧，第四对置面322位第二于打印机侧端子部3602的+Y轴方向侧。第三安装位33的第三打印机侧端子部3603安装在安装板35之间，且两边安装板35上分别具有第五对置面331和第六对置面332。第五对置面331位于第三打印机侧端子部3603的-Y轴方向侧，第六对置面332位于第三打印机侧端子部3603的+Y轴方向侧。第四安装位34的第四打印机侧端子部3604安装在安装板35之间，且两边安装板35上分别具有第七对置面341和第八对置面342。第七对置面341位于第四打印机侧端子部3604的-Y轴方向侧，第八对置面342位于第四打印机侧端子部3604的+Y轴方向侧。
图4中省略了部分打印机侧端子部，方便观察。打印机侧端子部的结构都是一样的。安装板35朝向打印机侧端子部的一侧具有凸起，具体的，如图3和图4所示，安装部30上设置有：第一凸起351、第二凸起352、第三凸起353、第四凸起354、第五凸起355、第六凸起356、第七凸起357、第八凸起358。第一凸起351、第二凸起352设置在第一安装位31上。第三凸起353、第四凸起354设置在第二安装位32上。第五凸起355、第六凸起356设置在第三安装位33上。第七凸起357、第八凸起358设置在第四安装位34上。以第一安装位31为例说明。第一凸起351设置在第一对置面311上，是从第一对置面311向第一安装位31内部突出形成的凸起。即，第一凸起351是从第一对置面311上朝向+Y轴方向侧突出的凸起。第二凸起352设置在第二对置面312上，是从第二对置面312向第一安装位31内部突出形成的凸起。即，第二凸起352是从第二对置面312上朝向-Y 轴方向侧突出的凸起。在Z轴方向上，第一凸起351、第二凸起352位于同一位置且相对设置。打印机侧端子部包括基座以及多个触针，触针设置在基座上，且多个触针呈多行排列，凸起位于多行触针之间。示例性的，在Z轴方向上，多个触针分为两排交错排列。如图4所示，第一打印机侧端子部3601有9个触针，沿+Z轴方向上，9个触针排列成2列，分别为第一列R1、第二列R2。在Z轴方向上，第一凸起351、第二凸起352在第一列R1、第二列R2之间。即，第一凸起351、第二凸起352在第一列R1的+Z轴方向侧，第一凸起351、第二凸起352在第二列R2的-Z轴方向侧。容易理解的是，如此设置可使墨盒上芯片定位更加准确。
第三凸起353、第五凸起355、第七凸起357与第一凸起351在其各自的安装位上的结构和位置一致，不在重复阐述。第四凸起354、第六凸起356、第八凸起358与第二凸起352在其各自的安装位上的结构和位置一致，不在重复阐述。
图7为本申请实施例提供的打印设备的安装部结构示意图。在安装板35上还可以设置有底部凹槽。具体的，在安装板35上依次设置有第一凹槽39a、第二凹槽39b、第三凹槽39c、第四凹槽39d和第五凹槽39e。以第四安装位为例进行说明，图7仅仅表示出了第四凹槽39d和第五凹槽39e。在安装板35上设置有第四凹槽39d和第五凹槽39e。第四凹槽39d和第五凹槽39e分别设置在第四打印机侧端子部3604的-Y轴侧和+Y轴侧。第六凸起356、第七凸起357分别设置在第四凹槽39d的左右两侧。具体的，第六凸起356设置在第四凹槽39d的-Y轴侧，第七凸起357设置在第四凹槽39d的+Y轴侧，第八凸起设置在第五凹槽39e的的-Y轴侧。第一凹槽39a、第二凹槽39b、第三凹槽39c、第四凹槽39d和第五凹槽39e均呈倒U型形状，且第一凸起351至第八凸起358均位于凹槽的肩部位置。
当墨盒40安装到安装部30上时，第一定位凸台与第七凸起357相接合，第二定位部与第八凸起358相接合，防止墨盒40在Y轴方向上的偏移，防止墨盒40脱离安装部30。此结构简单，安装操作容易、墨盒能够稳固的固定在安装部30内。同时，防止墨盒40特别是芯片440在Y轴方向上的偏移。更好的实现了芯片440与打印机侧端子部之间的电连接。
实施例二：
图5为本申请实施例提供的一种墨盒的结构示意图，图6为本申请实施例提供的一种墨盒的部分放大示意图。
参考图5至图6所示，坐标系和当墨盒40安装到安装部30的安装部30的坐标系方向一致。本申请实施例提供的一种墨盒40具有第一壁40a、第二壁40b、第三壁40c、第四壁40d、第五壁40e、第六壁40f。当墨盒40安装到安装部30时，第一壁40a、第二壁40b、第三壁40c、第四壁40d、第五壁40e、第六壁40f分别与安装部30的底壁30a、开口30b、第一侧壁30c、第二侧壁30d、第三侧壁30e、第四侧壁30f相对应。墨盒40包括：盒体420、出墨口430、芯片440。第一壁40a与第二壁40b在Z轴方向上相对设置，第三壁40c与第四壁40d在X轴方向上相对设置，第五壁40e与第六壁40f在Y轴方向上相对设置，第三壁40c、第四壁40d大致垂直于第一壁40a与第二壁40b，第五壁40e、第六壁40f大致垂直于第一壁40a、第二壁40b、第三壁40c、第四壁40d。第一壁40a在第二壁40b的-Z轴方向侧，第三壁40c在第四壁40d的-X轴方向侧，第五壁40e在第六壁40f的-Y轴方向侧。第一壁40a、第二壁40b、第三壁40c、第四壁40d、第五壁40e、第六壁40f围成内有墨腔的盒体420。出墨口430设置在第一壁40a上，芯片440设置在第三壁40c上。
墨盒40还包括：至少一个设置在第五壁40e或者第六壁40f上的定位部450，定位部450具有定位凸台，示例性的，定位部具有第二定位凸台452，第二定位凸台452到盒体420的第一壁40a的距离小于或等于芯片440到盒体420的第一壁40a的最大距离，第二定位凸台452到盒体420的第一壁40a的距离大于或等于芯片440到盒体420的第一壁40a的最小距离，即在Z轴方向上，定位凸台在芯片440在Z轴方向的覆盖区域的范围之内。当墨盒40安装到安装部30上时，第二定位凸台452与第一凸起351至第八凸起358中的相应凸起相卡合防止墨盒40脱离安装部30。此结构定位凸台452靠近芯片440。一方面可防止墨盒在竖直方向上脱离打印设备的安装部，结构简单，安装操作容易，能将墨盒稳固的固定在打印设备的安装部中，另一方面，可防止墨盒特别是芯片在芯片所在侧壁的延伸方向上的偏移，并且，避免了因定位凸台远离芯片造成的芯片偏移误差大的情况。墨盒40沿-Z轴方向安装到安装部30上，当需要把墨盒40从安装部30中取出来的时候，墨盒40沿+Z轴方向脱离安装部30。
如图5所示，当正视第三壁40c的时候，芯片440的最下端(-Z轴侧端部)的平行于Y轴的线为第一线D1、芯片440的最上端(+Z轴侧端部)的平行于Y轴的线为第二线D2，第一线D1与第二线D2之间的区域是芯片440在Z轴方向的覆盖区域T。定位凸台452在芯片440在Z轴方向的覆盖区域T的范围之内。定位凸台452到盒体420的第一壁40a的距离A小于或等于芯片440到盒体420的第一壁40a的最大距离B2，定位凸台452到盒体420的底面的距离A大于或等于芯片440到盒体420的底面的最小距离B1。具体的，最大距离B2是芯片440最上端到第一壁40a的距离，最小距离B1芯片440最下端到第一壁40a的距离。

其中，多个端子均设置有与打印设备中的触针相连接的接触部，接触部呈多行排布，最下行接触部最邻近第一壁40a，最上行接触部最远离第一壁40a，第二定位凸台452到第一壁40a的距离小于或等于最上行接触部到第一壁40a的距离，第二定位凸台452到第一壁40a的距离大于或等于最下行接触部到第一壁40a的距离。
芯片440包括多个端子，示例性的，如图6所示，芯片440包括9个端子。
芯片440具有第一端子、第二端子、第三端子和延伸端子。具体的，第一端子分别为复位端子442、时钟端子443、电源端子446、接地端子447和数据端子448，进一步的，第一端子中的部分端子是连接芯片440的存储器(一般设置在芯片的背面，图中未示出)的；第二端子分别为左高压端子445和右高压端子449；第三端子分别为左安装检测端子441和右安装检测端子444；延伸端子分别为左延伸端子442a和右延伸端子443a。
在一种可能实施的方式中，多个端子呈四行排布，沿着远离第一壁40a的方向上依次排列为第一行、第二行、第三行、第四行。如图6所示，具 体的，芯片440具有缺口，缺口分别位于芯片440的左右两端。芯片440的9个端子排列为4行。第一端子、第二端子和第三端子在安装方向上分四排排列，沿与+Z轴方向依次为第一行L1、第二行L2、第三行L3、第四行L4。进一步的，第一端子中的一部分(具体的，电源端子446、接地端子447、数据端子448)位于第一行L1；第二端子位于第二行L2；第一端子中的另一部分(具体的，复位端子442、时钟端子443)位于第三行L3；第三端子于第四行L4。其中，延伸端子设置在第三行L3上，并与第一端子中的另一部分(具体的，复位端子442、时钟端子443)同行设置。
具体的，在本实施例中，左延伸端子442a通过左细线连接部与复位端子442相连接，右延伸端子443a通过右细线连接部与时钟端子443相连接。左延伸端子442a可以连接到复位端子442、时钟端子443、电源端子446、接地端子447、数据端子448的任意一个端子上；右延伸端子443a连接到复位端子442、时钟端子443、电源端子446、接地端子447、数据端子448的任意一个端子上。
其中，第二定位凸台452设置在第一行端子远离第一壁40a的一侧，和/或，第二定位凸台452设置在第四行端子的靠近第一壁40a的一侧。进一步的，第二定位凸台设置452设置在第二行端子的远离第一壁40a的一侧，和/或，第二定位凸台452设置在第三行端子的靠近第一壁40a的一侧。在Z轴方向上，定位凸台设置在第一行L1和第四行L4之间。进一步的，在Z轴方向上，定位凸台设置在第二行L2和第三行L3之间。具体的，定位凸台设置在第一行L1和/或第二行L2的+Z轴方向侧，定位部设置在第三行L3和/或第四行L4的-Z轴方向侧。此结构，对于芯片440特别是端子的定位更加准确(特别是Y轴方向的位置)，防止端子不能与打印机侧端子部能够良好的电连接的情况。
可选地，定位部可以只有一个，也可以有2个或者多个。如图5和图6所示，本实施例中定位部包括具有的第一定位凸台451(在图5中被芯片440遮挡了)、第二定位凸台452；第一定位凸台451设置在第五壁40e上，第二定位凸台452设置在第六壁40f上。第一定位凸台451是从第五壁40e上向-Y轴方向上突出而形成的凸台，第二定位凸台452是从第六壁40f上向+Y轴方向上突出而形成的凸台。在Z轴方向上，第一定位凸台451、第二定位凸台452位于同一位置且相背设置。第一定位凸台451设置在芯 片440的-Y轴方向上，第二定位凸台452设置在芯片440的+Y轴方向上。在Z轴方向上，第一定位凸台451、第二定位凸台452设置在第一行L1、第二行L2的+Z轴方向侧，第一定位凸台451、第二定位凸台452设置在第三行L3、第四行L4的-Z轴方向侧。当墨盒40安装到安装部30上时，第一定位凸台451、第二定位凸台452与第一凸起351至第八凸起358中的相应凸起相卡合防止墨盒40脱离安装部30。此结构，第一定位凸台451、第二定位凸台452设置在第一行L1、第二行L2的+Z轴方向侧，在第三行L3、第四行L4的-Z轴方向侧，使得第一定位凸台451、第二定位凸台452对于芯片440特别是端子的定位更加准确(特别是Y轴方向的位置)，防止端子不能与打印机侧端子部能够良好的电连接的情况。
当墨盒40安装到安装部30上时，第一定位凸台451和第二定位凸台452与相应的凸起相接合，避免墨盒40脱离安装部30。如此，墨盒结构简单，安装操作容易、墨盒40能够稳固的固定在安装部30内，芯片440能够准确的与打印机侧端子部产生电连接。具体的，以墨盒40安装到第一安装位31为例说明，墨盒40安装到安装部30的顺序：A.墨盒40沿-Z轴方向从安装部30的开口30b移向底壁30a。B.第一定位凸台451与安装部30中第一对置面311相接触、第二定位凸台452与安装部30中的第二对置面312相接触，开始引导墨盒40。C.墨盒40继续下移，第一定位凸台451、第二定位凸台452到达第一凸起351、第二凸起352的位置处。D.墨盒40继续向-Z轴方向移动，第一定位凸台451的+Z轴侧与第一凸起351的-Z轴侧相抵靠在一起，第二定位凸台452的+Z轴侧与第二凸起352的-Z轴侧相抵靠在一起，墨盒40安装到位。E.此时，芯片440与第一打印机侧端子部3601电连接，出墨口430与供墨部330相匹配。
具体的，在墨盒40安装到安装部30的过程中，第一定位凸台451与安装部30中第一对置面311相接触、第二定位凸台452与安装部30中的第二对置面312相接触，引导墨盒40。在墨盒40安装过程中，第一对置面311和第二对置面312对墨盒40起引导作用，防止墨盒40在Y轴方向上的偏移。有效的避免了墨盒40不能准确的安装到安装部30的情况。墨盒40安装到其他安装位的过程和卡合位置及效果是一致的，不在重复阐述。
当打印机有打印需求时，墨腔内的墨水会沿着出墨口430、供墨部330到达打印头处，进而完成打印工作。
第一定位凸台451与第一凸起351相接合，第二定位凸台452与第二凸起352相接合，防止墨盒40在Y轴方向上的偏移。第一定位凸台451、第二定位凸台452设置在芯片440在Z轴方向的覆盖区域T的范围之内。此结构第一定位凸台451、第二定位凸台452靠近芯片440。一方面可防止墨盒在竖直方向上脱离打印设备的安装部，结构简单，安装操作容易，能将墨盒稳固的固定在打印设备的安装部中，另一方面，可防止墨盒特别是芯片在芯片所在侧壁的延伸方向上的偏移，并且，避免了因定位凸台远离芯片造成的芯片偏移误差大的情况。
第一定位凸台451、第二定位凸台452设置在第一行L1和/或第二行L2的+Z轴方向侧，在第三行L3和/或第四行L4的-Z轴方向侧，使得第一定位凸台451、第二定位凸台452对于芯片440特别是端子的定位更加准确(特别是Y轴方向的位置)，防止端子不能与打印机侧端子部能够良好的电连接的情况。
可选地，可以在墨盒的-X轴侧增加一个弹性件。可以使得墨盒在X轴方向上有一定的活动空间，且可以保证墨盒40可以更好的固定到安装部30上。弹性件可以是与墨盒40本体之间具有一定距离的可活动件、弹簧、硅胶、橡胶等弹性材料。
还可以在第一壁40a或者第三壁40c的上部位置处增加一个手持部，手持部是为了方便使用者取出墨盒40时使用者手部施力。手持部可以是增加摩擦力的防滑纹461(如图5所示)，也可以是与墨盒40本体之间具有一定距离的可活动件，也可以是固定在墨盒本体上的凸起等部件。供墨部330可以是供墨针也可以是供墨管。
在墨盒的-X轴侧增加一个可活动的把手，可以使得墨盒在X轴方向上有一定的活动空间，且可以保证墨盒40可以更好的固定到安装部30上。
墨盒40上的第一定位凸台451、第二定位凸台452可以是与墨盒本体一体注塑成型的凸起；也可以是第一定位凸台451、第二定位凸台452被配置在一个可替换部件上，如此同一结构可匹配多种不同的墨盒结构；还可以是单独黏贴、卡设等方式安装在第三壁40c上的凸起部件；此外还可以是黏贴、卡设、过盈配合等方式安装在第三壁40c上的具有弹性的凸起部件，此弹性的凸起部件可以是硅胶、橡胶、木塞等材料制成的。
图8为本申请实施例提供的另一种墨盒的放大示意图。
参考图8所示，至少一个定位部设置在第五壁40e或者第六壁40f上，具体的，至少一个定位部还包括：定位板，定位板设置在第五壁40e或者第六壁40f上。比如：第一定位板45a是从第五壁40e与第三壁40c上的交界位置上向+X轴方向上延伸出来的，第一定位板45b是从第六壁40f与第三壁40c上的交界位置上向+X轴方向上延伸出来的。定位凸台位于定位板上，定位凸台在芯片440在Z轴方向上的覆盖区域T的范围之内。
芯片440包括多个端子，多个端子呈多行排列，在Z轴方向上，定位凸台在多排之间。
在一种可能实施的方式中，定位部还包括：弹性臂，弹性臂的一端与定位板连接，弹性臂的另一端与定位凸台连接，示例性的，如图8所示，第一弹性臂45A一端与第一定位板45a连接，另一端与第一定位凸台451连接，第二弹性臂45B一端与第一定位板45b连接，另一端与第二定位凸台452连接。
第一弹性臂45A和第二弹性臂45B具有弹性。本实施例中，第一弹性臂45A和第二弹性臂45B是具有弹性的，第一定位凸台451、第二定位凸台452设置在第一弹性臂45A和第二弹性臂45B的-Z轴端部。第一定位凸台451是从第一弹性臂45A朝向-Y轴方向侧突出而形成的凸起，第二定位凸台452是从第二弹性臂45B朝向+Y轴方向侧突出而形成的凸起。以墨盒40安装到第一安装位为例说明：当墨盒40安装到安装部30上时，第一定位凸台451与第一凸起351相接合，第二定位凸台452与第二凸起352相接合，防止墨盒40在Y轴方向上的偏移，防止墨盒40脱离安装部30。第一弹性臂45A和第二弹性臂45B至少一部分具有弹性，第一定位凸台451、第二定位凸台452设置在延伸壁第一弹性臂45A和第二弹性臂45B的-Z轴端部。此结构使得墨盒40在安装过程中更加顺畅、不会出现卡死的情况。从安装部30中取出墨盒40时，更加的方便，使用者在取出墨盒40时的取出力更小。
当然，第一定位凸台451、第二定位凸台452的形状可以不同，例如在第一定位凸台451的+Z轴侧是倾斜向下的平面，第二定位凸台452的+Z轴侧是一个水平面。当墨盒40安装到安装部30内的时候，倾斜向下的平面与第一凸起351相接合，水平面与第二凸起352相接合。此结构，使得墨盒40更加稳固的与安装部30相接合。如此，两个定位部的形状不同， 可以使得墨盒具有一定的浮动空间，不会产生卡死的情况。在此，对定位凸台的形状不做具体限定。
实施例三：
现有技术中，打印机的安装部包括孔、安装腔、供墨部、打印机侧端子部。墨盒包括把手、墨腔、出墨口、芯片。墨盒的把手上设置有卡合位，用于与孔相匹配。当墨盒安装到安装部上时，卡合位进入到孔内，且与孔相卡合，从而将墨盒固定到安装部的安装腔内，防止墨盒脱离安装部。同时，芯片与打印机侧端子形成电连接，出墨口与供墨部相匹配，以便将墨腔内的墨水供给给打印机的打印头，为打印工作提供墨水。
然而，虽然安装部的孔限制了卡合位上下方向的移动以及水平方向的前后移动，但是却无法限制卡合位在水平方向的左右移动，从而导致芯片无法与打印机侧端子部形成良好的电连接或者打印机无法正确识别墨盒的芯片的情况。

D.墨盒40继续向-Z轴方向运动，当接合部423越过触针362后，触针362的第一部分362a位于对端子与接合部423之间的空间内；且同时墨盒安装到位，芯片440上端子的接触部4408与触针362电连接，出墨口430与供墨部330相匹配。
当墨盒40需要从安装部30中取出时的过程：
A.使用者手握把手470与第墨盒40的后侧壁对墨盒施加向+Z轴方向的力。
B.使得接合部423沿着第一部分362a的外形相对滑动，触针362向+X轴方向变形。
C.当墨盒40的接合部423脱离触针362时，安装部30对墨盒40的卡合作用解除。
D.墨盒40继续向+Z轴方向运动，即可将墨盒40取出。
进一步地，如图9所示，此配合方式：在墨盒40安装到安装部30上时，接合部423的过渡面4232与触针362的底部362z相接合，可以保证墨盒40对触针362的反作用力不足以让第一触针362向-X轴方向形变。当墨盒40需要取出时，使用者对墨盒40施加向+Z轴方向的力，使得触针362向+X轴方向发生形变，进而使得墨盒40脱离安装部30。
如图31所示，此配合方式：在墨盒40安装到安装部30上时，接合部423的过渡面4232与触针362的底部362z相接合，可以保证墨盒40对触针362的反作用力不足以让触针362向-X轴方向形变。当墨盒40需要取出时，使用者对墨盒40施加向+Z轴方向的力，使得触针362向+X轴方向发生形变，进而使得墨盒40脱离安装部30。此配合方式比起图9所示的 配合方式，接合部423起接合作用的是过渡面122，第一触针362起起接合作用的是更靠近尖顶部362y的部分，如此结构墨盒40更容易从安装部30中取出，且不易损坏触针362。
进一步的，接合部423的过渡面4232可以与触针362的底部362z相接合，也可以是接合部423的水平面4233可以与触针362的底部362z相接合。触针362的底部362z是第一部分362a在X轴方向上最宽的位置处的下方部分，故第一部分362a位于尖顶部362y的-Z轴方向的部位均为底部362z。过渡面4232可以为圆弧面、也可以为斜面。优选的，过渡面4232与Z轴方向形成角度大于0度。
在正常状态下，为了避免芯片440上的晶元受到磨损，可选的，第三壁40c上具有凹陷部4404，凹陷部4404可容纳芯片440的至少一部分和接合部423的至少一部分，凹陷部4404为开设在第三壁40c上与芯片440对应的位置，凹陷部4404作为对芯片440上晶元的避让凹部，避免了芯片440安装在第三壁40c上时位于芯片内侧的晶元受到磨损。
进一步的，接合部423也可以是多个，例如，接合部423的数量是2个，都是部分容纳在凹陷部4404中的凸起，且延伸到芯片440的多个凹部4402处。2个接合部423与2个触针362的底部362z相接合。再例如，接合部423的数量是4个，都是部分容纳在凹陷部4404中的凸起，且延伸到芯片440的4个凹部4402处。4个接合部423与4个触针362的底部362z相接合。又比如，接合部423的数量是2个，都是部分容纳在凹陷部4404中的凸起，且延伸到芯片440的2个凹部4402位置处。接合部423与设置在打印机侧端子部最底端两侧的触针362的底部362z相接合。
需要注意的是，墨盒40上的接合部423可以是与墨盒本体一体注塑成型的凸起；也可以是接合部423被配置在一个可替换部件上，如此同一结构可匹配多种不同的墨盒结构；还可以是单独黏贴、卡设等方式安装在第三壁40c上的凸起部件；此外还可以是黏贴、卡设、过盈配合等方式安装在第三壁40c上的具有弹性的凸起部件，此弹性的凸起部件可以是硅胶、橡胶、木塞等材料制成的。
实施例五：
图32为本申请实施例五提供的墨盒示意图。在墨盒40的第三壁40c上，没有设置把手470，此实施方式也是可以实现本申请的有益效果的。
另一方面，也可以在墨盒40的第三壁40c的+Z轴侧上设置有一些防滑纹，也是可以实现本申请的有益效果的。在取出墨盒40时，防滑纹可以起到防止使用者手与墨盒40之间的相对滑动。
芯片440与实施例一的芯片不同。如图32所示，芯片440的电源端子446、接地端子447、数据端子448设置在芯片440的正面及断面位置处。芯片440的电源端子446、接地端子447、数据端子448与相应触针的斜坡部或者第一垂直部分相接触。其余端子与相应触针的尖顶部相接触。芯片440的电源端子446、接地端子447、数据端子448的-Z轴方向上具有凹部17。接合部423上设置在凹孔14上的凸起，且延伸到凹部17位置处。当墨盒40安装到安装部30上时，多个触针362的第一部分362a与接合部423之间的空间内，接合部423与各触针的底部相接合，防止墨盒40脱离安装部30。此结构，同一个接合部423可以与多个触针的底部接合，使得墨盒40结构更简单，墨盒40可以更稳固的固定到安装部30上。
其余与实施例一一致。
实施例六：
图33为本申请实施例六提供的墨盒示意图。墨盒40的第三壁40c是倾斜的与第一壁40a相交的。墨盒还设置有第二壁44c2。第三壁40c是与第一壁40a、第二壁44c2倾斜相交的，位于第一壁40a和第二壁44c2之间的角部上。芯片440和接合部423设置在倾斜的第三壁40c上。当墨盒40安装到安装部30上时，芯片440与触针362相接触，接合部423与触针的底部相接合，防止墨盒40脱离安装部。
图33中示出了触针362。芯片440上的端子设置在芯片440的正面及断面上，端子呈一排排列。端子与触针的斜坡部相接触。
具体的，此实施例中端子只有4个端子，且4个端子都是设置在芯片440的正面及断面上。
当墨盒40安装到安装部上时，触针的第一部分位于对端子与接合部423之间的空间内，接合部423与触针底部相接合，防止墨盒40脱离安装部。
在墨盒40上还设置有把手470、第二卡合部480。把手470具有第一卡合部471。第一卡合部471、第二卡合部480也可以与安装部上的相应部分接合，防止墨盒40脱离安装部。这样可以保证墨盒40可以更好的固定到安装部上。
当墨盒40需要取出安装部时，使用者手捏把手470，使得第一卡合部471与安装部相脱离；同时施加+Z轴方向的力，使得接合部423与触针相脱离；继而第二卡合部480与安装部脱离；墨盒40即可顺利取出。
过渡面4232可以为圆弧面、也可以为斜面。优选的，过渡面与第一侧壁之间的角度大于0度。
其余与实施例一一致。
实施例七：
在一种可选实施方式中，墨盒40的第三壁40c是倾斜的与第一壁40a相交的，图34为本申请实施例七提供的墨盒示意图，如图34所示，墨盒40还设置有第二壁44c2，第三壁40c是与第一壁40a、第二壁44c2倾斜相交的，位于第一壁40a和第二壁44c2之间的角部上，芯片440设置在第三壁40c上，在第三壁40c上设置有两个接合部423，分别为13a和13b。接合部423a、13b设置在第三壁40c上。当墨盒40安装到安装部30上时，芯片440与触针362相接触，接合部423a、13b与触针362的底部362z相接合，防止墨盒40脱离安装部30。
在墨盒40上还设置有卡合部4407，卡合部4407也可以与安装部上的相应部分接合，防止墨盒40脱离安装部。
接合部分为接合部423a、13b。两个接合部423a、13b位于同一高度，两个接合部423的结构相同，也可以不同。其中一个接合部423a的顶面131a可以设置成倾斜面，另一个接合部423b的顶面131b设置成水平面。安装部30上的两个安装板35的锁止面与两个接合部423的顶面相匹配， 即其中一个安装板35的锁止面可以设置成倾斜面，另一个安装板35的锁止面设置成水平面。通过两个形状不同的接合部423与两个安装板35的锁止面相抵接，使得墨盒40具有一定的浮动空间，从而避免墨盒40卡死在安装部30的情况。
其余与实施例一一致。
实施例八：
另一种可选的实施方式，第三壁40c上设置有两个接合部423，两个接合部423位于同一高度，两个接合部423的形状相同。两个接合部423的顶面131可以设置成弧形面。安装部30上的两个安装板35的锁止面与两个接合部423的顶面131相匹配，即锁止面为弧形面。通过两个接合部423与两个安装板35的锁止面相抵接，可以使得芯片440与打印机侧端子部准确定位电连接。
可选地，其中一个接合部423的顶面131设置成弧形面，另一个接合部423的顶面131设置成平面。
示例性地，第三壁40c上设置有两个接合部423，两个接合部423位于同一高度，两个接合部423的形状不同。其中一个接合部423a的顶面131a可以设置成弧形面，另一个接合部423b的顶面131b设置成水平面。安装部30上的两个安装板35的锁止面与两个接合部423的顶面131相匹配，通过两个形状不同的接合部423与两个安装板35的锁止面相抵接，使得墨盒40具有一定的浮动空间，从而避免墨盒40卡死在安装部30的情况。本实施例也可以达到本申请的有益效果。
