Description

【技术领域】
本发明涉及一种用于喷墨打印机上的墨盒。
【背景技术】
现有的与喷墨打印机配套使用的墨盒， 其结构主要包括盒体、 在压力作用 下与盒体可相对移动的保护盖、 用于检测墨盒的墨盒检测机构和用于检测墨水 剩余量的墨水剩余量检测机构， 盒体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、 大气进口。 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返回到第二传感器的接收部， 接着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， 此时打印机提示墨盒安装完成， 进行下一部 操作。 现有墨盒实现墨盒的检测和墨水量检测的机构如图 1 所示， 包括第一检 测部件 a、 第二检测部件 b、 第三检测部件 c、 透光部 d和可动杆件 e, 此方案的 检测机构主要是通过对传感器所发出的光的遮挡来实现的， 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 b遮挡， 随着墨盒的装入， 第二传感器所发出的光不被不透光的第二 检测部件 b遮挡而接通， 接着第一传感器所发出的光被第一检测部件 a遮挡， 最后第二传感器所发出的光也被不透光的第三检测部件 c 遮挡， 此时打印机提 示墨盒存在， 可进行下一步操作， 第三检测部件 c由一透光部 d和一不透光的 可动杆件 e组成，可动杆件 e的位置可通过墨盒内墨水量的变化而发生变化，第 二传感器所发出的光可根据是否被第三检测部件 c 遮挡来实现墨盒内墨水量的 检测。 由此可见， 该墨盒的墨盒安装检测中必须使用墨盒墨水剩余量检测机构 即第三检测部件的遮挡， 导致墨盒的墨盒安装检测不能独立进行而受到墨水剩 余量的影响， 如当完成没有剩余墨水的墨盒安装时， 实际上完成了安装， 而打 印机却可能提示没有完成安装， 安装未完成告警与墨水用完告警不能明确区分。

所述腔体内设置有一个可浮于墨水上方的可移动检测部件。
所述腔体透明壁部还设置有墨水量显示标识。
在釆用了上述技术方案后， 由于第二检测部件包括遮挡部、 设置于盒体的 固定轴、 设置于保护盖的活动轴和遮挡部位置恢复件， 遮挡部与固定轴转轴连 接， 在活动轴的压力下围绕固定轴旋转， 并可在遮挡部位置恢复件的作用下与 保护盖一起恢复位置。 最后遮挡第二传感器发射部所发出的光仍然是遮挡部而 不是墨水剩余量检测机构中部透光的可动杠杆， 因此不会受墨水剩余量的影响， 解决了现有用于喷墨打印机的墨盒安装检测中必须使用墨盒墨水剩余量检测机 构而导致墨盒安装检测不能独立进行而受到墨水剩余量影响的技术问题， 实现 安装报警与墨水用完告警完全分离。 其次， 由于墨水剩余量检测机构包括设置 于盒体内的触发开关和与触发开关串联的发光灯， 发光灯设置于遮挡部靠近第 二传感器的一侧并与电源电连接,触发开关在墨水没用完时为断开状态,在墨水 用完时为接通状态。 不但除去了复杂的杠杆结构，而且釆用了精度极高的触发开 关,能精确的检测墨水剩余量， 而且可在不改变原来打印机的墨水告警的系统的 情况下直接使用本发明的墨盒， 墨水剩余量的检测只需通过发光灯是否发光来 控制第二传感器是否导通来实现墨水剩余量检测。 再次， 由于墨水剩余量检测 机构包括设置于盒体内的触发开关和与触发开关串联的警示机构， 警示机构与 电源电连接,触发开关在墨水没用完时为断开状态,在墨水用完时为接通状态。 直 接利用警示机构向外界发出警示， 不但结构简单， 而且可靠性高。 最后， 由于 墨水剩余量检测机构釆用了与墨水腔连通的由透明材料制成的腔体,使用者只需 要打开打印机墨盒仓的盖即可肉眼观察到墨水的剩余量,可据此估计到剩余墨水 可使用的时间，尽早准备要添加的墨水,在腔体内设置可浮于墨水上方的可移动 检测部件,使观察墨水的剩余量更加清楚，腔体透明壁部设置有墨水量显示标识， 使观察墨水的剩余量更加精确。
