Description

一种用于喷墨打印机的墨盒
技术领域
本发明涉及一种用于喷墨打印机的墨盒。
说
背景技术 书
与喷墨打印机配套使用的墨盒，其结构主要包括用于储存墨水的 储墨腔、 向打印机的打印头供墨的出墨口、用于检测墨盒和检测墨水 剩余量的检测部件。为了保证墨盒装进打印机后能够正常工作， 墨盒 必须包含两种检测机构， 在把墨盒安装到打印机的过程中， 首先一检 测机构使打印机上的第二传感器发射部所发射的光不能返回第二传 感器的接收部， 随着安装的进行， 第二传感器发射部所发射的光能回 到第二传感器的接收部，此后另一检测机构使第一传感器发射部所发 出的光不能回到第一传感器的接收部， 最后， 第一、 第二传感器相对 应的发射部所发出的光都不能回到相对应的接收部，进而完成了安装 的检测， 此时打印机提示进行下一部操作。所述墨盒检测和墨水量检 测主要采用的技术措施有：此方案的检测机构主要是通过对传感器所 发出的光起遮挡作用来实现的，其工作原理是：当墨盒装入打印机时， 首先打印机内部的第二传感器所发出的光被不透光的第二检测部件 遮挡，其次第二传感器所发出的光不被不透光的第二检测部件遮挡而 接通， 而第一传感器所发出的光被第一检测部件遮挡， 最后第二传感 器所发出的光被不透光的第三检测部件遮挡，而第一传感器所发出的 光被第一检测部件遮挡， 此时打印机提示墨盒存在， 可进行下一步操 作， 所述第三检测部件由一透光部和一不透光的可动杆件组成， 可动 杆件的位置可通过墨盒内墨水量的变化发生变化，第二传感器所发出 的光可根据是否被第三检测部件遮挡来实现墨盒内墨水量的检测。
这种技术由于可动杆件位于墨水腔内，所以墨水的表面张力会将 第三检测部件吸附， 造成装机及墨水量检测的失误。 鉴于以上墨盒的缺陷，专利 CN200910105619. 8揭示了人们发明 的另一种墨盒， 即检测的可活动杆件位于墨水腔外面的墨盒， 可活动 杆件可以随弹片的移动而移动充当了装机检测时的第二检测部件和 第三检测部件， 墨尽检测配合随墨水量变化的软体支撑帽的形变， 可 活动杆件发生移动， 进而完成墨尽检测。于是打印机上第二传感器匹 配的第二检测机构和设置于盒体上与储墨腔相通的软体支撑帽配合， 所述第二检测机构包括可活动杆件、设置于盒体的轴和设置于墨盒上 的弹片， 所述可活动杆件通过轴与盒体转轴连接， 弹片在可活动杆件 的重力作用下可与可活动杆件下边抵接。在装机时， 弹片不再抵接可 活动杆件。可活动杆件依靠重力发生绕轴移动， 还未到垂直位置时与 软体支撑帽抵接。 这样完成了墨尽检测。 具体如图 1所示， 原来喷墨 打印机墨盒 1包括： 检测墨水剩余量的墨水检测机构， 包括： 与打印 机上传感器相匹配的检测部件 102， 和设置于盒体上的和墨水储存腔 相通的软体支撑帽 3 ; 这样墨水储存腔内墨水用尽后， 软体支撑帽就 会变形， 传感器发射出的光线就会被改变； 但是软体支撑帽的硬度较 难控制， 和遮挡部件自身重力配合时， 往往会造成检测错误。 另一方 面， 遮挡部件在软体支撑帽 3不支撑时， 依靠自身重力移动， 当有墨 水附着或其他异物存在于遮挡部件上时，由于墨水张力或异物的吸附 力， 造成杠杆组件移动出现偏差。传感器检测也会出现错误。 由此根 据本发明所提供的实施例，采用弹力的方式克服了第二遮挡部件工艺 误差及外物的影响造成的检测错误。
上述专利中的技术方案存在以下缺点：由于可活动杆件的质量的 大小以及软体支撑帽的厚薄和墨水袋内部的压力都是不易控制的，工 艺实现难度较高。例如当可活动杆件的质量较大， 而软体支撑帽较薄 时， 可能墨盒内部有墨水， 但软体支撑帽不足以支撑可活动杆件。造 成墨盒的装机检测失误， 同时墨尽检测也错误。

所述墨水储存腔内还设置有弹性元件，所述弹性元件设置在杠杆 与柔性薄膜固定连接的对应位置处。
所述杠杆的一端与柔性薄膜的外表面固定连接。
所述杠杆的一端与柔性薄膜的内表面固定连接，所述杠杆穿过所 述墨水储存腔的位置处设置有出口孔，所述出口孔与所述杠杆件设置 有密封圈。 在采用了上述技术方案后， 由于增加了拉力生成部件， 所述拉力 生成部件产生一个使可活动杆件向墨盒安装反方向移动的拉力，在进 行装机检测时拉力生成部件产生一个使可活动杆件向墨盒安装反方 向移动的拉力而不需要依靠可活动杆件的重力来进行装机检测，可活 动杆件的重力对装机检测几乎无影响，解决了现有用于喷墨打印机的 墨盒装机检测受到可活动杆件重力影响而导致装机检测失误的技术 问题。还包括将墨盒内部的墨水剩余量转化为对可活动杆件作用力的 传递部件，传递部件将墨盒内部的墨水剩余量转化为对可活动杆件作 用力而使可活动杆件偏离或处于墨水量检测位置来检测剩余量，也提 高了墨水剩余量的检测精度。 附图说明

如图 2所示， 本发明实施例的墨盒 1， 包括： 墨水储存腔 11 (图 7所示）， 装机检测机构 第一检测部件 2和可活动杠杆件 6， 墨水 量检测机构 可活动杠杆件 6和杠杆组件 9 (图 7所示），出墨口 8， 弹出机构 复位部件 4。
其中， 墨水储存腔 11 内部存有一定量墨水， 至少一个外壁由可 变型的薄膜构成。 并通过出墨口 8向打印机提供油墨。
装机检测机构包括第一检测部件 2 和第二检测部件， 第二检测 部件包括可活动杠杆件 6和轴 7。
在墨盒装机过程中， 可活动杠杆件 6的遮挡第二信号区域 61将 第二传感器 102发出的第二信号第一次遮挡。 随即， 第一检测部件 2 将第一传感器 104发出的第一信号遮挡，并持续整个装机过程。随后， 可活动杠杆件 6在复位部件 4和拉力生成部件 5的共同作用下，沿与 装机方向相反的方向绕轴 7旋转， 偏离第二传感器 102， 并不再遮挡 第二传感器 102。 第二遮挡部件 6在绕轴 Ί旋转到杠杆组件 9一端的 抵接部 93时， 被抵接部 93抵住， 并不再继续移动。 装机继续进行， 第二传感器 102再次被可活动杠杆件 6的遮挡第二信号区域 61遮挡。 至此第一传感器 104被第一检测部件 2遮挡，第二传感器 102被可活 动杠杆件 6遮挡， 装机检测完毕，复位部件 4为弹片， 弹片一端与盒 体的前壁固定连接， 另一端与打印机墨盒容纳空间的壁抵接， 弹片上 设置有支撑位；可活动杆件被复位部件上的支撑位支撑， 支撑位可以 为支撑缝，也可以为挂钩。
墨水量检测机构包括第二遮挡部件 6和杠杆组件 9， 其中杠杆组 件 9包括杠杆 91和杠杆转轴 95，杠杆 91的一端为斜面形的抵接部 93， 杠杆 91的另一端形成平板 92。 当然杠杆组件也可以用能将墨盒内部 的墨水剩余量转化为对可活动杆件作用力的其它传递部件如与储墨 腔连通的支撑帽替代。
在检测墨水量过程中， 当墨水消耗到一定量时（2-3ml )， 墨水储 存腔 11的可变型的薄膜壁发生较大形变， 杠杆 91的平板 92与薄膜 固定连接， 平板 92沿 L方向 （图 7所示）移动， 杠杆 91通过杠杆转 轴 95联动抵接部 93， 抵接部 93偏移抵接可活动杠杆件 6的位置， 并不再抵接可活动杠杆件 6。 可活动杠杆件 6在拉力生成部件 5的力 F (图 8所示） 作用下， 偏移开遮挡第二传感器 102的位置， 不再遮 挡第二传感器信号。 由此打印机检测墨盒 1内部墨水量将要耗尽。
出墨口 8包括一密封部件。在墨盒装机后与打印机供墨针配合密 封， 防止墨水泄露。在未装机时， 密封部件自密封可防止墨水存储腔 11内墨水泄露。 弹出机构包括复位部件 4， 在墨盒不被固定卡杆 105卡住时， 复 位部件 4可将墨盒 1从墨盒仓 10中弹出， 方便墨盒拆装。
在墨盒 1拆离墨盒仓 10时， 复位部件 4可将可活动杠杆件 6复 位至装机初始状态的位置。
如图 3所示， 打印机的墨盒仓 10包括： 打印机供墨口 101， 第 二传感器 102， 凸起 103， 第一传感器 104和固定卡杆 105。
其中：
打印机供墨口 101在墨盒 1装机后， 与墨盒的出墨口 8配合， 可 将墨水传输到打印头。
第二传感器 102可配合第一传感器 104完成墨盒 1的装机检测功 能， 并在墨盒 1内部墨水量变化后， 完成墨盒内部的墨水量检测。
凸起 103可抵接复位部件 4， 使复位部件 4处于形变状态。 第一传感器 104可配合第二传感器 102完成墨盒 1的装机检测功 能。
固定卡杆 105， 通过与墨盒上部的凸起配合， 可将墨盒 1固定在 墨盒仓 10内。
如图 4所示， 墨盒在装机过程中， 可活动杠杆件 6的遮挡第二信 号区域 61将第二传感器 102发出的第二信号第一次遮挡。 而第一检 测部件 2未遮挡第一传感器 104， 墨盒仓 10上的固定卡杆 105在墨 盒 1装机过程中处于偏离固定位的位置。在墨盒装机完成后回复到固 定位置。
如图 5所示， 墨盒装机完成后， 第一传感器 104被第一检测部件 2遮挡， 第二传感器 102被可活动杠杆件 6遮挡。 并且打印机墨盒仓 10上的凸起 103抵接墨盒 1的复位部件 4。复位部件 4处于形变状态。 墨盒仓 10上的固定卡杆 105在墨盒 1装机后处于固定位置。 打印机 供墨口 101与墨盒出墨口 8密封连接。
如图 6所示，墨盒 1内部的配合墨水量检测的机构为杠杆组件 9， 杠杆组件 9可随墨水腔一薄膜壁的变化而绕轴发生移动，配合完成墨 水量检测。 由于打印机供墨口有一定的抽吸力， 可将墨盒 1的墨水储 存腔 11内部的墨水抽出。 墨水储存腔 11只有出墨口 8与外部连接， 所以当墨水减少时， 墨水储墨腔 11的体积发生变化， 随之墨水储存 腔 11的薄膜壁发生形变。
如图 7所示，杠杆组件 9一端的平板 92与墨水储存腔 11的薄膜 壁固定连接， 可才用双面胶粘合， 或由固定卡位连接。在薄膜壁发生 形变时， 平板 92沿 L方向移动， 杠杆 91通过杠杆转轴 95联动抵接 部 93， 抵接部 93偏移抵接可活动杠杆件 6的位置， 并不再抵接可活 动杠杆件 6。
由于墨盒 1的薄膜壁会产生形变，而薄膜的形变位置跟薄膜的厚 度和所受压力有关。 为了确保在墨水将要耗尽时， 平板 92与薄膜连 接处才发生形变， 所以在墨水储存腔 11内部， 平板 92对应的位置加 装一弹簧 24，平衡内部压力，使平板 92与薄膜连接处最后发生形变。
如图 8所示， 在装机检测过程中， 可活动杠杆件 6绕轴 7移动， 开始时可活动杠杆件 6位于第一位置， 其遮挡第二信号区域 61将第 二信号遮挡。在装机过程中， 可活动杠杆件 6在拉力生成部件 5的力 F的作用下发生移动。 当碰到杠杆组件 9的抵接部 93时， 其抵接力 f 中和力 F， 使可活动杠杆件 6停留在第二位置。 此位置为墨盒装机后 的遮挡位置， 可活动杠杆件 6位于第二位置时， 其遮挡第二信号区域 61将第二信号第二次遮挡。 装机检测完成。
如图 9所示，本发明第一实施例中墨盒的拉力生成部件 5采用弹 簧结构。 弹簧一端固定在可活动杠杆件 6上， 一端与复位部件抵接。 对可活动杠杆件 6的弹力沿 F (图 8所示） 方向。
如图 10所示， 本发明第二实施例中墨盒的拉力生成部件 5采用 拉簧结构。 弹簧一端固定在可活动杠杆件 6上， 一端与墨盒 1固定。 对可活动杠杆件的拉力沿 F (图 8所示） 方向。
如图 11所示， 本发明第三实施例中墨盒的拉力生成部件 5采用扭簧 结构。扭簧一端固定在可活动杠杆件 6上， 一端与轴 7固定连接。对 可活动杠杆件的扭力沿 F (图 8所示） 方向。
拉力生成部件也可以为一组相吸磁铁，其中一个磁极设置在墨盒 壁上， 一个磁极设置在可活动杆件上。
拉力生成部件还可以为一组相斥磁铁，其中一个磁极设置在复位 部件上， 一个磁极设置在可活动杆件上。
