通常， 墨盒芯片上设置有用于存储信息的存储介质和多个与该存储介质 相连接的触点，该多个触点在墨盒装入打印机后会与打印机侧的触针相接触， 以在墨盒芯片和打印机之间建立电连接。

进一步地， 墨盒芯片安装在墨盒或结构体上时， 所述第二平面平行于墨盒或 结构体插入喷墨打印机的插入方向。
本发明另一个方面提供一种墨盒， 可拆卸地安装在喷墨打印机上， 包 括根据上述任一项所述的墨盒芯片。
本发明再一方面还提供一种结构体， 可拆卸地安装在喷墨打印机上， 包括用于容纳墨盒的腔体以及上述任一项所述的墨盒芯片。
由上述技术方案可知， 本发明提供的墨盒芯片、 墨盒及结构体， 通过 在电路板上表面积较小的第二平面上设置各容器侧端子， 且各容器侧端子 贯穿第二平面而设置， 即各容器侧端子排列成一行， 使得各容器侧端子的 定位精度要求降低， 进而使得装置侧端子较容易地接触到容器侧端子， 从 而提高墨盒和打印机之间电连接的稳定性。 附图说明 图 1为现有技术中墨盒芯片的触点分布示意图；

本实施例提供一种墨盒芯片， 该墨盒芯片适用于墨盒， 尤其适用于喷 墨式打印机的墨盒。 本实施例的墨盒芯片可拆卸地安装在墨盒或结构体 上。 其中， 墨盒或结构体可拆卸地安装在喷墨打印机上。
如图 2所示， 为根据本实施例的墨盒芯片的立体结构示意图。 本实施 例的墨盒芯片 200包括电路板 201和多个容器侧端子 202。
其中， 电路板 201包括第一平面 203和与第一平面 203垂直相交的第 二平面 204， 第二平面 204的表面积小于第一平面 203的表面积； 各容器 侧端子 202设置于第二平面 204上， 且每个容器侧端子 202的一端与第一 平面 203相交， 每个容器侧端子 202的另一端与第三平面 （图中未示出） 相交， 第三平面与第一平面 203相对， 容器侧端子 202用于与装置侧端子 (图中未示出） 相接触。
本实施例的电路板 201可以用于承载各种元器件， 例如电容或者电阻 等。 本实施例中的各容器侧端子 202具体可以为触点， 该容器侧端子 202 可以为矩形， 具体可以是导电性材料制作成的金属薄片。 装置侧端子具体 可以是打印机上的触针。
可选地， 第二平面 204可以为一矩形， 第二平面 204中最长的边 W和 T分别为第一平面 203与第二平面 204的第一交界线、 以及第二平面 204 与第三平面的第二交界线。 显然， 此时， 该容器侧端子 202的一端第一交 界线相交， 而其另一端则与第二交界线相交。
可选地， 墨盒芯片安装在墨盒或结构体上时， 第二平面 204平行于墨盒或结 构体插入喷墨打印机的插入方向。
根据本实施例的墨盒芯片 200， 通过在电路板 201上表面积较小的第 二平面 204上设置各容器侧端子 202， 且各容器侧端子 202贯穿第二平面 204而设置， 即各容器侧端子 202排列成一行， 使得各容器侧端子 202的 定位精度要求降低， 进而使得装置侧端子较容易地接触到容器侧端子， 从 而提高墨盒和打印机之间电连接的稳定性。 此外， 由于仅需要在墨盒芯片 200上设置一排容器侧端子， 相比于需要在墨盒芯片 200的精确位置设置 各容器侧端子而言， 工艺简单， 成本较低。
实施例二
本实施例基于实施例一提供一种墨盒芯片。
如图 3A所示， 为根据本实施例的墨盒芯片 200的立体结构示意图； 如图 3B所示， 为根据本实施例的墨盒芯片 200的俯视结构示意图； 如图 3C所示， 为根据本实施例的墨盒芯片 200的左视图， 如图 3D所示， 为根 据本实施例的墨盒芯片 200的第二平面 204的示意图。
本实施例的墨盒芯片 200的第二平面 204包括多个凹槽 301， 每个凹 槽 301中设置有一个容器侧端子 202，即凹槽 301的数量与容器侧端子 202 的数量一致， 当然凹槽 301的数量也可以多于或少于容器侧端子 202的数 量。 具体地， 容器侧端子 202可以布满该容器侧端子 202所在凹槽 301的 内表面。
可选地， 每个凹槽 301均贯穿于第二平面 204， 即凹槽 301的一端 P 与第一平面 203相交， 另一端 Q与第三平面相交。
可选地，本实施例中的墨盒芯片 200还包括如图 3C所示的存储器 302， 该存储器 302用于存储该墨盒芯片 200所在墨盒的相关信息， 例如墨盒中 的墨水量信息、墨水种类、墨盒的制造日期及厂商信息等等，该存储器 302 具体可以由 EEPR0M、 RAM, SRAM, Flash和 FRAM等各种存储介质构成。 该 存储器 302与至少一个容器侧端子 202相连接。
本实施例的凹槽 301可以为圆弧状， 如半圆形， 即凹槽 301在第一平 面 203上的投影为半圆状。 此外， 凹槽 301也可以设置为其它形状是， 例 如， 其截面可以为三角形、 矩形或梯形等， 具体可以根据实际需要设计， 只要能够容纳装置侧端子即可。
根据本实施例的墨盒芯片 200， 通过在第二平面 204设置能够夹持装 置侧端子的凹槽 301， 从而限制装置侧端子的移动， 当墨盒在打印机中快 速移动时， 可以减小装置侧端子的位移， 尽量保持装置侧端子与容器侧端 子 202的接触。
实施例三
本实施例基于对上述实施例的盒芯片做进一步具体说明。 本实施例中 提供一种墨盒， 包括上述任一实施例的墨盒芯片。
如图 4所示， 为根据本实施例的墨盒的结构示意图。 该墨盒 400可拆 卸地安装在喷墨打印机上， 并包括容器主体 401、 出墨口 402和墨盒芯片 200。
其中， 容器主体 401内部形成有用于容纳墨水的腔室（图中未示出）， 出墨口 402设置在容器主体 401的底壁上， 当墨盒 400装入打印机后， 打 印机的供墨针可以插入该出墨口 402中， 以将容器主体 401的腔室中的墨 水传输至打印机。本实施例的墨盒芯片 200可以与实施例一或实施例二一 致， 在此不再赘述， 本实施例中以实施例二的墨盒芯片 200为例做具体说 明。
可选地， 在出墨口 402中设置密封部件 （图中未示出） ， 该密封部件 可以包括阀机构、 焊接的薄膜等各种具有良好密封性的器件。 例如， 该密 封部件为一由硅胶制成的自闭密封圈， 由于硅胶具有良好的弹性， 使得墨 盒 400从打印机上拔出时， 该自闭密封圈被供墨针刺穿的部分可以恢复为 密闭状态， 从而防止墨水泄露。 另外， 容器主体 401的顶部还可设置一进 气口 （图中未示出） ， 该进气口用于使墨盒 400与外部大气连通， 并在墨 水消耗时及时补充大气至墨盒 400内部以调节内部压力。
墨盒 400的侧壁上还可以设置有一安装槽 403， 该安装槽 403可以容 纳墨盒芯片 200。 确切地说， 当墨盒芯片 200安装在安装槽 403中时， 墨 盒芯片 200上的各容器侧端子 202突出于上述安装槽 403而设置。优选地， 该安装槽 403延伸方向与墨盒 400插入喷墨打印机的插入方向相垂直， 即 墨盒芯片 200在墨盒 400上的安装方向与上述插入方向相垂直。也就是说， 此时， 墨盒芯片 200的第二平面 204平行于墨盒 400的上述插入方向， 即 墨盒芯片 200上设有容器侧端子 202的表面平行于墨盒 400的上述插入方 向。
图 5A为本实施例墨盒 400所适用的打印机侧的装置侧端子所在的接 触机构的示意图， 图 5B为单个装置侧端子的结构示意图。
从图 5A和图 5B中可以看出， 装置侧端子 500为呈山脊状、 活动的弹 性导电装置，该装置侧端子 500包括平滑区 501和接触区 502，接触区 502 相对于平滑区 501突出。本实施例中将平滑区 501和接触区 502交接的地 方标记为 。 本实施例中， 接触区 502呈 "厶" 字型。 接触区 502处设置 有一突出的且用于接触容器侧端子的接触形成部 5031， 且该接触形成部 5031相当于墨盒 400插入装置侧端子 500时的插入方向的垂直方向的最外 点。
本实施例中， 接触机构 510上设置有深度不同的多个狭缝， 每个狭缝 中均设置有一装置侧端子 500， 即有多个装置侧端子 500设置于接触机构 510上。如图 5B所示， 多个装置侧端子 500在墨盒 400插入打印机的插入 方向上以预设间排列成垂直于上述插入方向的两行 R1和 R2 , 且两两之间 交错排列。 R1和 R2之间间距可以设定为位于 R1行的装置侧端子 500的接 触形成部 5031与位于 R2行的装置侧端子 500的接触形成部 5031之间的 距离。
图 6A至图 6C为墨盒装置打印机过程中墨盒芯片与装置侧端子之间的 位置变化示意图， 图 6D为图 6C装置侧端子与容器侧端子相接触的放大示 意图。
如图 6A所示， 当墨盒 400装入打印机上时， 墨盒芯片 200位于接触 机构 510的上方。 随着墨盒 400的进一步装入， 如图 6B所示， 墨盒芯片 200中与 R1行对应的装置侧端子 500相接触， 确切地说， 墨盒芯片 200 上与 R1行的装置侧端子 500相对应的容器侧端子 202是与位于装置侧端 子 500的接触形成部 5031以及平滑区 501及接触区 502相交点 A之间的 区域相接触。 接着， 墨盒 400进一步装入， 墨盒芯片 200向下移动， 并带 动所接触的装置侧端子 500向下移动。 由于每个装置侧端子 500是弹性且 可动的， 则其会在相应的狭缝中活动， 即位于 R1行的装置侧端子 500随 着墨盒芯片 200的向下移动而向下变形， 此时， 凹槽 301均容纳一相应的 装置侧端子 500， 限制其在左右方向上的摆动， 尽量保证装置侧端子 500 与容器侧端子 202的接触， 该凹槽 301还能够起到引导装置侧端子 500向 下或向上移动的作用。 这样， 随着墨盒 400的逐步装入， 墨盒芯片 200上 的容器侧端子 202与装置侧端子 500分别都接触上之后， 打印机与墨盒芯 片 200之间就建立了通信， 如图 6C和图 6D所示， 图 6D为图 6C的 B区域 的放大示意图。 如图 6C和 6D所示， 当位于 R1行的装置侧端子 500向下 变形 （活动） 时， 由于其与位于 R2行的装置侧端子 500之间存在相互重 叠的区域， 故当墨盒芯片 200移动到两者的重叠区域时， 此时， 上述 R1 行与 R2行装置侧端子 500排列为一行。
本领域普通技术人员应理解， 上述位于 R1行的各装置侧端子 500与 位于 R2行的各装置侧端子 500之间可以不存在重叠区域， 此时只要保证 墨盒芯片 200移动至与两者均接触的情况即可在墨盒芯片 200与打印机之 间建立电连接。
可选地， 墨盒 400上还设有一用于实时监测墨水剩余量的压电传感器 (图中未示出），该传感器与墨盒芯片 200上的两个容器侧端子 202连接， 即该传感器经由两个容器侧端子 202与装置侧端子 500连接， 从而与打印 机连接， 进而能够接收施加在打印机上的驱动电压， 该驱动电压可以是 42V, 存储器 302的驱动电压一般为 3. 6V。 由于压电传感器的驱动电压与 存储器 302的驱动电压之间存在较大的电压差， 所以任一连接存储器 302 的低压的容器侧端子与任一连接电压传感器的高压的容器侧端子之间发 生短路， 电压传感器的驱动电压会施加在存储器 302上致使存储器 302烧 毁。 因此， 还可以在墨盒芯片 200上设置短路检测端子， 该短路检测端子 可以是容器侧端子 202中的一个或多个， 短路检测端子与打印机侧的装置 侧端子相接触从而与打印机上的短路检测电路相连接。 该短路检测端子可 以设置在低压的容器侧端子和高压的容器侧端子之间， 通过检测自身与高 压的容器侧端子之间的短路而判断存在高压的容器侧端子与低压的容器 侧端子之间短路的风险。
可选地， 如图 7所示， 墨盒芯片 200可以设置在一结构体 700上， 该 结构体 700可拆卸地安装在喷墨打印机上， 并且设有可容纳墨盒的腔体 701。而且，该结构体 700上还设有一容纳上述墨盒芯片 200的安装槽 702。 显然， 此时墨盒仅作为一储存墨水的容器， 未设有墨盒芯片 200。 安装槽 702在结构体 700上的延伸方向也垂直于结构体 700插入打印机的插入方 向， 墨盒芯片 200在结构体 700上的安装方向垂直于上述插入方向。 也就 是说， 此时， 墨盒芯片 200的第二平面 204平行于结构体 700的上述插入 方向， 即墨盒芯片上设有容器侧端子的表面平行于结构体 700的上述插入 方向。
可选地， 可以在 结构体 700上设置用于复位墨水量的复位电路， 当 墨盒中的墨水消耗完后， 墨盒芯片 200中的墨水量自动恢复为初始值， 此 时用户只需要更换墨盒或将原墨盒补充墨水即可。 由于墨盒芯片 200是造 价成本较高的一部分，通过结构体 700来使墨盒芯片 200与墨盒连接起来， 能够使同一墨盒芯片 200应用于多个墨盒中， 节省了成本。
可选地， 上述墨盒或结构体中还可以设置一连动机构（图中未示出）， 其中， 该连动机构一端与上述墨盒芯片 200相连接， 另一端则为操作部。 如此，当上述墨盒或结构体未使用时，上述墨盒芯片 200即位于安装槽 702 中； 而当上述墨盒或结构体使用时， 通过上述操作部的相应操作可将位于 安装槽 702中的墨盒芯片 200突出于安装槽 702以与打印机侧的容器侧端 子相接触； 而当需要取出墨盒 400时， 可以执行上述操作部而将墨盒芯片 200退回至安装槽内， 再执行拔出动作即可。
最后应说明的是： 以上实施例仅用以说明本发明的技术方案， 而非对 其限制； 尽管参照前述实施例对本发明进行了详细的说明， 本领域的普通 技术人员应当理解： 其依然可以对前述各实施例所记载的技术方案进行修 改， 或者对其中部分技术特征进行等同替换； 而这些修改或者替换， 并不 使相应技术方案的本质脱离本发明各实施例技术方案的范围。
