Description

一种喷墨打印机上的适配器及与之配套使用的墨盒
本申请要求于 2009 年 05 月 13 日提交中国专利局、 申请号为 200910039523.6, 发明名称为 "一种喷墨打印机上的适配器及与之配套使用 的墨盒" 的中国专利申请的优先权， 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及一种喷墨打印机上的适配器及与之配套使用的墨盒。 背景技术
在现有的一些系列型号的打印机中， 有的用户采用了与喷墨打印机配套 使用的适配器及墨盒， 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、 大气进口部分， 保持墨水腔稳定负压的阀结构， 向打 印机提供墨盒信息的芯片及用于定位芯片的打印机适配器（如图 1所示， 图 1 为现有打印机适配器及墨盒的示意图 ) 。 其工作方式是： 先将适配器 2装 入打印机， 适配器 2包含一个带墨水信息的芯片 1 , 适配器 2装入打印机后， 芯片 1上的各触点与打印机上的触点紧密配合。 然后将墨盒 5装入适配器 2 中， 使打印机的供墨针插入墨盒 5的出墨口。 打印机开始正常工作。 墨尽后， 打印机提示更换墨盒 5 , 将墨盒 5取出， 重新更换墨盒 5。 打印机会重新读取 墨水信息， 打印机就可继续工作了。
其中， 在打印机工作时， 芯片 1上的各触点与打印机上的触点是组成一 接通的回路的， 打印机可以检测芯片 1上的墨水量信息； 当更换墨盒时， 必 须将上述回路断开， 打印机在检测到该回路断开时， 才能够得知墨盒更换的 动作， 对打印机上存储的墨水量信息进行擦除， 以便获取更新后墨盒的墨水 量信息。 否则， 若回路不断开， 打印机则不对其上存储的墨水量信息进行擦 除， 将导致该信息与芯片上所存储的更新后墨盒的信息不一致， 打印机将报 错无法打印。
但是， 现有技术中所存在的问题是， 在更换墨盒时， 若不将适配器取出， 则芯片与打印机连接的回路将一直处于接通状态， 其无法实现自动断开， 由 此就可能造成上述的打印机报错无法打印的情况。 因此， 目前部分系列打印 机在打印机中设置的一组程序， 使芯片必须脱离打印机才能复位。 即使用打 印机适配器的用户在更换墨盒时， 必须将墨盒与适配器全部取出后， 才能使 得上述的回路断开， 重新安装墨盒后才能达到更换目的。 这样增加了适配器 的拆装工序， 减少适配器的使用寿命， 增加了使用者的工作量以及使用成本。 发明内容

当芯片 1 内的墨水量信息达到一定值时， 复位装置会使墨水量信息自动 复位， 打印机提示更换墨盒 5。 本实施例中的非接触式触发开关可以为磁力 开关。 所述非接触式触发开关可以设置在所述芯片的两检测电触点相反的背 面或同一表面。 将墨盒 5从适配器 2中取出， 在非接触式触发机构 4行经磁 力开关 3的作用范围时，磁力开关 3内部的磁铁 33被非接触式触发机构 4吸 引沿定位柱 32向非接触式触发机构 4移动， 离开原来的闭合位置， 此时芯片 1 内部电路断开如图 8所示， 图 8为本发明所配合的打印系统模块化电路原 理图。 在非接触式触发机构 4离开磁力开关 3的作用范围后， 磁铁由自身磁 力吸引向与检测电触点相连的触点 31方向移动， 直至接触， 此时磁力开关 3 闭合。 再装入新的墨盒 5后， 通过反向的步骤触发装置会再次断开芯片 1的 电路一次,打印机读取芯片 1上的墨水信息， 打印机会提示墨盒可用。 与检测 电触点相连的触点 31与两检测电触点分别电连接，磁力开关 3在墨盒 5插入 打印机过程中被如图 6所示墨盒 5上的非接触式触发机构 4触发断开至少一 次， 在墨盒 5插入后不被非接触式触发机构 4触发而为接通状态， 非接触式 触发开关与非接触式触发机构 4之间通过磁场作用力控制非接触式触发开关 的接通和断开， 非接触式触发开关为常闭磁力开关， 所述常闭磁力开关有与 非接触式触发机构产生磁力作用的金属， 例如可以为磁铁； 或者， 所述非接 触式触发开关为常闭磁力开关， 所述常闭磁力开关有一个弹性部件和一铁磁 性物质。 所述非接触式触发开关上的磁铁 33的磁通量为 500 ~ 1500高斯。 非 接触式触发机构 4为可与非接触式触发开关产生磁力作用的磁铁或铁磁性物 质。 所述非接触式触发机构 4上的磁铁的磁通量为 1000 ~ 5000高斯。
先将适配器 2装入打印机。 此时， 芯片 1 电路导通， 打印机读取芯片 1 信息； 再将墨盒 5装入适配器 2后， 墨盒 5侧壁上的非接触式触发机构 4如 图 6所示在安装过程中， 行经芯片 1的磁力开关 3作用范围时， 使芯片 1内 部电路断开； 然后墨盒 5继续装入， 离开芯片 1的磁力开关 3作用范围， 直 到安装到预定位置， 芯片 1 电路闭合。 此时打印机提示有墨盒 5 , 并读取墨 水信息， 打印机提示新装入的墨盒 5可用。
待墨尽后， 芯片 1 自动复位。 打印机提示更换墨盒 5 , 将墨盒 5从打印 机适配器 2中取出时， 墨盒 5侧壁上的触发装置再次划过芯片 1的磁力开关 3。 芯片 1的内部电路再次断开一次。 当新的墨盒 5装入后， 墨盒 5触发装置 再次通断一次芯片 1 内部电路。 此时打印机读取复位后的墨水信息， 打印机 可继续工作。
其中， 所述非接触式触发机构预埋在与适配器芯片的非接触式触发开关 对应侧壁的墨盒内， 所述非接触式触发机构的触发行程轨迹经过非接触式触 发开关的触发区域。 所述非接触式触发机构固定设置于墨盒侧壁上， 所述非 接触式触发机构的触发行程轨迹经过非接触式触发开关的触发区域。 所述非 接触式触发机构活动设置于墨盒侧壁上， 所述非接触式触发机构的触发行程 轨迹经过非接触式触发开关的触发区域。 非接触式触发机构与该触发区域内 的非接触式触发开关的有效作用距离是 3 ~ 10mm。
本发明通过墨盒 5侧壁上的触发装置即非接触式触发机构触发芯片 1开 关将芯片 1激活， 从而促使打印机读取墨水信息并达到检测墨盒 5是否存在 的目的， 这样以来， 可以将适配器 2永久装入打印机， 用户只需更换不带芯 片 1的墨盒 5即可。 实施例二
图 9为本发明喷墨打印机上的适配器中的芯片的结构示意图， 如图 9所 示， 本实施例的适配器中的芯片与实施例一的芯片的主要区别在于， 芯片 1 上的非接触式触发开关可以是干簧管开关。 本发明还提供了一种低成本、 方便使用者使用的墨盒， 该墨盒上设置有 与芯片的非接触式触发开关相匹配的非接触式触发机构。 该墨盒可以与实施 例一或二所述的适配器进行配套使用。
其中， 所述非接触式触发机构为可与非接触式触发开关产生磁力作用的 磁铁。 所述非接触式触发机构上的磁铁的磁通量为 1000 ~ 5000高斯。
所述非接触式触发机构为可与非接触式触发开关产生磁力作用的铁磁性 物质。 所述非接触式触发机构预埋在与适配器芯片的非接触式触发开关对应 侧壁的墨盒内， 所述非接触式触发机构的触发行程轨迹经过非接触式触发开 关的触发区域。 或者， 所述非接触式触发机构固定设置于墨盒侧壁上， 所述 非接触式触发机构的触发行程轨迹经过非接触式触发开关的触发区域。或者， 所述非接触式触发机构活动设置于墨盒侧壁上， 所述非接触式触发机构的触 发行程轨迹经过非接触式触发开关的触发区域。
非接触式触发机构与该触发区域内的非接触式触发开关的有效作用距离 是 3 ~ 10mm。 本实施例的墨盒与适配器配合动作的过程可以参见实施例一所 述。 本实施例通过在墨盒的侧壁上设置非接触式触发机构触发芯片开关将芯 片 1激活，从而促使打印机读取墨水信息并达到检测墨盒 5是否存在的目的， 这样以来， 可以将适配器 2永久装入打印机， 用户只需更换不带芯片 1的墨 盒 5即可。
应当说明的是， 以上实施例仅用以说明本发明的技术方案而非限制， 所 有的参数取值可以根据实际情况调整， 且在该权利保护范围内。 本领域的普 通技术人员应当理解， 可以对本发明的技术方案进行修改或者等同替换， 而 不脱离本发明技术方案的精神范围， 其均应涵盖在本发明的权利要求范围当 中。
