Description

负压式墨盒填充装置、 系统及填充方法 技术领域
本发明主要涉及用于喷墨墨盒再填充的填充装置、填充系统及填充方法 , 尤其涉及一种负压式墨盒填充装置、 墨盒填充系统及填充方法。 背景技术
喷墨打印机， 其打印方式通常是由用于容纳墨水的墨盒提供墨源， 经由 相应的墨水流动通道将墨水输送至记录头中， 并在打印信号的驱动下将墨水 从记录头上设置的喷嘴喷射至纸张等记录介质上，来完成字符或图形的记载。
按照记录头与墨盒的配置关系， 喷墨打印机墨盒包括两种类型： 一体式 墨盒和分体式墨盒。 一体式墨盒的记录头与墨水储存室合二为一， 且记录头 设置在墨盒的出墨口上； 分体式墨盒的记录头与墨水储存室相互分离， 墨水 储存室仅容纳墨水， 而记录头则设置在喷墨打印机的字车上。 由于一体式墨 盒的记录头容易损坏， 且记录头的价格较高， 使得越来越多的用户选择分体 5 呈、 。
目前， 市场上常见这样的一种分体式墨盒， 其结构为： 墨盒包括负压腔 及墨水腔， 两腔之间通过一连通口而连接， 且负压腔中设有用于产生毛细力 以保持墨水的海绵体及与打印机供墨针相连接的出墨口， 墨水腔中设有一注 墨口。 显然， 若该分体式墨盒墨水耗尽后直接丟弃， 其中的塑胶、 薄膜等组 成部分大多不能自然降解， 如此， 容易造成资源浪费及环境污染。 为此， 优 选的方式是： 对耗尽墨水的墨盒进行二次墨水填充， 使其获得二次使用价值。 中国专利 CN200910109293.6提出一种负压墨盒填充装置：该填充装置包 括用于储存填充用墨水的储墨容器、用于将墨水输送至待填充墨盒的供墨管、 位于墨水容器上方的抽吸通道及抽吸器， 其中， 抽吸通道与墨水容器直接相 连， 且其与抽吸器连接以抽吸墨水容器中的空气。
利用上述负压墨盒填充装置对上述分体式墨盒进行填充的过程为： 将待 填充墨盒固定在填充装置上， 此时， 墨盒的出墨口与供墨管连接， 且储墨容 器与墨盒之间形成一密闭空间； 然后， 将抽吸器与抽吸通道连接， 抽吸储墨 容器及墨盒内的空气； 然后， 放开抽吸器， 则此时墨盒由于气压平衡自动吸 收储墨容器内的墨水， 即墨水经由供墨管进入负压腔， 再经由连通口进入墨 水腔。
在墨盒填充装置的运输过程中， 如果环境因素的变化， 如温度升高等， 而致使储墨容器内部的压力升高， 由于此时供墨管的墨水进入端自始至终都 是浸在墨水中， 则墨水会在压力的作用下进入供墨管中， 此时， 若用户打开 供墨管的密封部件， 其中的墨水则会飞溅出来， 污染环境及弄脏用户的手及 衣物。
此外， 墨盒填充后， 由于供墨管中墨水的阻隔作用， 容易使墨盒中几乎 不具有负压， 则取出墨盒时， 负压腔的海绵体处于饱和状态， 容易发生滴墨 的现象。 发明内容

为使本发明实施例的目的、 技术方案和优点更加清楚， 下面将结合本发 明实施例中的附图， 对本发明实施例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发明一部分实施例， 而不是全部的实施例。 基于 本发明中的实施例， 本领域普通技术人员在没有做出创造性劳动前提下所获 得的所有其他实施例， 都属于本发明保护的范围。
本发明的主要技术方案为： 注墨通道的入口端位于墨水容器的墨水水平 面上方， 且待填充墨盒进行填充时， 在填充完后需要将墨盒旋转一定角度， 将入口端从浸在墨水中变成位于墨水水平面的上方。 显然， 采用上述技术方 案， 在墨盒填充装置的运输过程中， 即使墨水容器中压力升高， 墨水也难以 进入注墨通道中， 为此， 用户在初次使用墨盒填充装置时， 只有空气排出， 而不会出现溅墨的现象； 而且， 使得墨盒中保持一定的负压， 当取下墨盒时， 海绵体不会发生过饱和的现象。
下面通过附图和具体实施例，对本发明的技术方案做进一步的详细描述。 图 1为本实施例中待填充墨盒的结构示意图。 如图 1所示， 墨盒 15内部 利用隔板 153分成负压腔 151与墨水腔 152, 且两者通过位于隔板 153下方 的连通口 1531而相互连接， 使得墨水腔 152除连通口 1531外， 基本上形成 一密闭的空间。 其中， 负压腔 151 中包含有用以保持墨水的吸收构件， 该吸 收构件大多采用多孔性材料制成， 如海绵体 1511 , 且负压腔 151的底壁上设 有用于给打印机的记录头供墨的出墨口 154, 负压腔 151 的顶壁上设有将外 部大气输送至墨盒 15中的导气口 156。 因此， 随着负压腔 151中的墨水被消 耗用于记录， 在墨水腔 152中的墨水通过上述连通口 1531进入负压腔 151 , 同时负压腔 151中的空气也经由连通口 1531而进入墨水腔 152中，即墨水腔 152中的墨水与负压腔 151中的空气通过连通口 1531而进行交换。 而且， 随 着在负压腔 151中的空气与墨水腔 152中的墨水不断交换， 外部大气可通过 上述导气口 156而补充进入负压腔 151中。
此外， 出墨口 154中往往还设置有一棉芯 157, 其密度比负压腔 151 中 的海绵体 1511高，当墨盒 15用于打印时，其用于引导墨水流动至出墨口 154; 而且， 该墨盒 15上还设置有注墨口 155 , 其位于墨水腔 152的上方， 通常在 首次灌墨后利用钢珠进行密封， 防止墨盒 15在运输中或使用中发生泄漏。 同 时， 墨盒 15上还设有用于检测墨水腔 152的墨水余量的棱镜， 位于墨水腔 152 的底壁上。 利用棱镜检测墨水余量的过程为本领域的成熟技术， 在此不 作赘述。 如图 1所示， 墨盒 15上还设有具有第一接合部分 159的可动杆件 158和第二接合部分 160,该第一接合部分 159和第二接合部分 160可在墨盒 图 2a为本发明实施例中墨盒填充装置的前侧面示意图， 图 2b为本发明 实施例中墨盒填充装置的后侧面示意图， 图 3为本发明实施例中墨盒填充装 置结构的分解示意图， 图 4a为本发明实施例中待填充墨盒与墨盒填充装置的 配合示意图， 图 4b为本发明实施例中墨盒填充装置进行填充的位置示意图。 由图 2a至图 4b中可知， 墨盒填充装置 1包括： 墨水容器 2, 储存有填充至上 述待填充的墨盒 15中的墨水； 注墨通道 3 , 用于将墨水容器 2中的墨水输送 至墨盒 15中， 包括一与上述墨盒 15的出墨口 154连接的出口端 31及引导墨 水从墨水容器 2流入注墨通道 3中的入口端 32; 抽吸通道 4, 与墨水容器 2 连通， 设有一抽吸口 41 , 用于在进行填充时抽吸墨水容器 2及墨盒 15中的 空气而使墨水容器 2及墨盒 15中形成负压； 抽吸器 12, 与抽吸通道 4的抽 吸口 41连接以抽吸墨水容器 2及墨盒 15中的空气，其由筒身 121、活塞 123、 活塞杆 124及手柄 122组成， 其中， 活塞杆 124与活塞 123固结在一起， 并 且活塞 123可在筒身 121 中上下移动以抽吸或排出空气； 墨盒定位机构 5, 用于将墨盒 15定位于墨盒填充装置 1中， 其上设有与墨盒 15的第一接合部 分 159、 第二接合部分 160相配合的相应结构， 其与墨水容器 2之间可以通 过卡位连接或通过焊接而形成一体， 在本实施例中， 优选地， 其与墨水容器 2之间通过注塑而一体成型， 且如图 3所示， 为更好地限定墨盒 15在其中的 位置， 墨盒定位机构 5的内侧还设有部分肋条 51 , 且在其一侧壁上设有一卡 槽 52; 上盖 6, 其一端与墨盒定位机构 5通过铰链而连接， 即上盖 6可绕墨 盒定位机构 5旋转一定的角度， 而其另一端则设有卡扣 62, 可与设置在墨盒 定位机构 5的侧壁上的卡槽 52彼此扣合， 使得当墨盒 15装入墨盒定位机构 5后， 上盖 6可将其固定在墨盒填充装置 1中。
如图 4a所示， 上盖 6上还设有一密封部件 61 , 以将该墨盒 15密闭地固 定在墨盒填充装置 1中。 其中。 该密封部件 61由凸出部分 611及硅胶套 612 组成： 凸出部分 611 , 设置在上盖 6内侧， 并与墨盒 15上的导气口 156相对 应， 确切地说， 当上盖 6与墨盒定位机构 5彼此卡合后， 凸出部分 611可覆 盖在导气口 156上； 硅胶套 612, 由弹性材料制成， 与凸出部分 611的尺寸 相当， 可包围上述凸出部分 611 ; 为此， 当上盖 6旋转以固定墨盒 15时， 密 封部件 61可密封导气口 156, 防止外部空气进入墨盒 15中， 使得墨盒 15除 出墨口 154与墨水容器 2连接外基本上为一密闭的空间， 确切地说， 此时， 墨盒填充装置 1及墨盒 15形成一密闭的空间， 也可以说， 上述密封部件 61 也对墨盒 15具有一限制作用 , 使其不得向上移动， 保证墨盒 15被充分固定 在墨盒填充装置 1中。
如图 4a所示， 注墨通道 3的入口端 32位于墨水容器 2的墨水水平面的 上方， 故墨盒填充装置 1未使用时注墨通道 3中均为空气， 无墨水， 则在运 输过程中， 即使环境因素发生变化或其它原因致使墨水容器 2的压力升高， 墨水也无法进入注墨通道 3中， 故用户初次使用墨盒填充装置 1时， 拔出出 口端 31的密封机构时， 只是注墨通道 3的空气排出， 不会出现溅墨的现象， 从而防止墨水污染环境或弄脏用户的手或衣物等情况的出现。
如图 3及图 4a所示， 墨盒填充装置 1上还包括用于密封注墨通道 3的出 口端 31的密封机构， 在本实施例中， 该密封机构由密封圈 7、 胶塞 8及套筒 9组成。 其中， 密封圈 7采用硅胶、 橡胶等弹性材料制成， 其上设有一凹部， 凹部中间设有一自闭缝， 可根据两侧的压力差而选择性地封闭或展开， 且该 密封圈 7与出口端 31相配合； 胶塞 8由上部与下部组成， 其中， 下部的直径 与上述密封圈 7的凹部相当， 而上部的直径则与套筒 9的内径相当， 因此， 胶塞 8与密封圈 7的凹部相配合， 套筒 9则与胶塞 8相配合。 如此设置的目 的是为了防止墨盒 15填充装置在运输过程中， 如空运， 由于墨水容器与外部 大气之间的压力差的作用而致使密封圈 7的自闭缝打开而造成墨水泄漏， 即 采用该结构后， 若密封圈 7的自闭缝打开时， 由于胶塞 8的封堵， 墨水无法 流出。 其中， 套筒 9由工程塑料制成， 胶塞 8采用橡胶或硅胶制成， 这是因 为： 为了使墨盒填充装置 1小型化， 其上方容纳墨盒 15的空间较为狭窄， 若 仅用胶塞 8进行密封上述凹部， 则用户在使用时需要将手伸入狭窄的空间以 取出胶塞 8, 较为麻烦， 为此， 设置一套筒 9, 其可与胶塞 8配合成一体， 且 套筒 9的长度较长， 略小于墨盒定位机构 5的高度， 则用户在使用时只需要 拔出套筒 9即可拔出胶塞 8, 打开注墨通道 3 , 简单方便。
此外， 在本实施例中， 抽吸通道 4的抽吸口 41采用自闭密封圈 10进行 密封， 该自闭密封圈 10采用硅胶制成， 具有良好的弹性， 且其中间设有一腔 体， 且腔体与抽吸通道 4连通的壁上设有一贯穿自身的自闭缝。 平时该自闭 缝为关闭状态， 当抽吸器 12插入时， 自闭缝变为开启状态， 使得抽吸器 12 与墨水容器 2之间连通。 如图 2a所示， 墨盒填充装置 1上还设有方便用户把 握墨盒填充装置 1的把持部 11 , 且该把持部 11由数条与墨盒填充装置 1的 外壁平行的凹槽形成， 而且该把持部 11 还可用作相邻填充装置之间的连接 部， 此时仅需要在另一填充装置的外部设有与上述凹槽形状吻合的凸起即可 (图中未示出） ， 这样方便用户将数个装载不同颜色墨水的填充装置连接在 一起。 如图 2b及图 3所示， 在上盖 6及墨水容器 2上， 与抽吸通道 4相对的 一侧上分别设有防滑垫 13及 14, 其由具有一定摩擦力或阻力的材料制成， 确保墨盒填充装置在填充时不容易发生滑动， 充分保证填充的顺利进行。
为使用户可以清楚地观察墨盒填充的状态， 优选地， 在本实施例中， 墨 盒填充装置 1使用透明材料制成。
以下根据图 2a至图 5 , 对墨盒填充装置 1的使用进行说明。
( 1 ) 将墨盒填充装置 1放置在一平面上， 捏住套筒 9, 拔出胶塞 8;
( 2 ) 如图 4a所示， 打开上盖 6, 将墨盒 15放置在墨盒填充装置 1上， 此时墨盒 15的可动杆件 158、第一接合部分 159及第二接合部分 160分别与 墨盒填充装置 1的墨盒定位机构 5的相应结构相配合而将墨盒 15定位在墨盒 填充装置 1上，保证墨盒 15的出墨口 154与注墨通道 3的出口端 31相连接， 然后， 旋转上盖 6, 使其上的卡扣 62与墨盒定位机构 5的卡槽 52相应的扣 合， 则上盖的密封部件 61抵住墨盒 15 , 并密封其上方的导气口 156, 则墨盒 15被固定在墨盒填充装置 1中，此时， 墨盒 15的连通口 1531位于出口端 31 的下方，注墨通道 3的入口端 32位于墨水容器 2的墨水水平面上方， 墨盒填 充装置 1及墨盒 15形成一密闭的空间， 形成一墨盒填充系统；
( 3 ) 将整个墨盒填充系统 1顺时针旋转 90。 ， 即使得设有防滑垫 13及 14的表面与上述平面接触， 此时由于防滑垫 13、 14与平面之间的摩擦作用， 可保证墨盒填充装置 1在上述平面上不会发生滑动， 此时注墨通道 3的入口 端 32浸在墨水中， 抽吸通道 4位于墨水容器 2的上方， 最重要的是， 墨盒 15的出墨口 154位于连通口 1531的上方， 即注墨通道 3的出口端 31位于即 将注入墨盒 15的墨水流通重力方向的上游；
( 4 ) 如图 4b所示，将预先准备好的抽吸器 12插入抽吸通道 4的抽吸口 41中， 使自闭密封圈 10的自闭缝打开， 抽吸器 12与墨水容器 2相连通， 然 后抓住抽吸器 12的手柄 122, 拉动活塞杆 124而带动活塞 123向上运动， 则 墨水容器 2中空气沿着如图 4c所示的箭头流向抽吸器 12, 而此时密封圈 7 在墨水容器 2及墨盒 15两侧的压差作用下， 打开自闭缝， 使得墨盒 15内的 气体同样会如图示箭头的方向经由注墨通道 3流向墨水容器 2, 再流向抽吸 器 12, 则墨水容器 2及墨盒 15中会形成一定的负压；
( 5 ) 如图 4d所示， 放开抽吸器 12的手柄 122, 此时， 根据密闭空间气 压平衡原理， 活塞 123在大气压的作用下慢慢向下运动， 促使墨水容器 2中 的墨水如图示箭头的方向， 经由墨水入口端 32、 出口端 31、 出墨口 154而进 入墨盒 15中， 由于此时连通口 1531位于出墨口 154的下方， 则墨水在重力 的作用会经由连通口 1531而流入墨水腔 152中，并停留在墨水腔 152的下方；
( 6 ) 再次拉动抽吸器 12进行抽气， 此时如图 4e的箭头所示， 墨水腔 152的上方空气被抽走， 然后放开抽吸器 12, 则同样地， 墨水容器 2中的墨 水被注入墨盒 15中， 且优先注入墨水腔 152中；
( 7 ) 上述过程反复进行， 直至观察到墨盒 15被注满墨水， 此时， 取下 抽吸器 12,则自闭密封圈 10再次封闭抽吸通道 4,再将整个墨盒填充系统逆 时针旋转 90。 ， 使得入口端 32再次位于墨水容器 2的墨水水平面上方， 如 图 4f所示;
( 8 ) 此时， 打开上盖 6, 取下墨盒 15 , 并利用原有的胶塞、 套筒等部件 重新密封出口端 31即可， 若墨盒 15上设置有芯片， 还需要利用芯片复位器 对芯片内部的信息进行复位。
由上述填充过程可知，在墨盒 15进行填充时，必须将墨盒填充系统旋转， 直至注墨通道 3的出口端 32位于墨盒 15的墨水流通重力方向的上游， 即使 得与出口端 31连接的出墨口 154位于连通口 1531的上方。 如此， 当进行墨 水填充时， 注入墨盒 15 的墨水会沿着其重力方向从出墨口 154流向连通口 1531 , 进入墨水腔 152, 并聚集在墨水腔 152的上方， 这样， 墨水腔 152上 方与连通口 1531连通的是空气， 故当多次抽吸时， 抽吸器 12只能抽吸到墨 水腔 152的空气， 而不能抽吸到已注入的墨水， 故能保证墨水腔 152容易注 满， 从而充分保证墨盒容易注满。
由上述填充过程可知， 在墨盒 15进行填充后， 必须将其先旋转至 "入口 端 32位于墨水容器 2的墨水水平面上方" 的状态后再取下墨盒 15 , 这是因 为： 由于抽吸器 12的活塞 123与筒身 121之间存在摩擦力， 则墨盒 15填充 完后， 活塞 123不会回到抽吸器 12未开始使用时候的位置， 即此时墨水容器 2中存在一定的负压； 而墨盒 15填充完后， 注墨通道 3中均为墨水， 即入口 端 32浸在墨水中， 则在水阻力的作用下， 墨盒 15的负压很少或说几乎不存 在负压， 为此， 此时若直接取下墨盒 15 , 由于海绵体 1511还是处于饱和或 过饱和的状态， 容易出现滴墨的问题； 但是， 若旋转后再取下墨盒 15 , 由于 此时注墨通道 3为空气， 墨水容器 2与墨盒 15之间连通， 故墨盒 15中同样 具有较大的负压， 则打开上盖 6时， 外部大气会进入负压腔 151 中， 则此时 由于物质平衡原理， 海绵体 1511中多余的墨水会流向墨水容器 2, 如图 5所 示， 使得海绵体 1511处于不饱和的状态， 取下墨盒 15时， 不会出现滴墨的 现象。
应注意， 抽吸口 41与入口端 32应分别位于或靠近墨水容器 2上相对的 两侧壁上， 即抽吸口 41与入口端 32总是相对设置， 且分布在墨水容器 2的 两侧， 为此， 当利用上述墨盒填充系统对墨盒 15进行填充时， 不管其开始填 充时是顺时针旋转放置还是逆时针旋转放置，都能保证入口端 32旋转后浸在 墨水中， 保证墨水可以填充至墨盒 15中。 本技术领域的技术人员， 应理解为， 上述待填充墨盒也可为无墨水腔、 仅设有海绵体的墨盒。
综上所述，通过使注墨通道 3的入口端 32位于墨水容器 2墨水水平面上 方， 出口端 31在填充时位于墨盒 15的墨水流通重力方向的上游， 且墨盒 15 进行填充后需进行一旋转动作，在墨盒填充装置 1的入口端 32位于墨水容器 2墨水水平面上方的状态下再取下墨盒 15 , 使得多次抽吸时不会将之前已注 入的墨水再抽出， 保证墨盒可充分注满墨水， 不会残留过多的气泡， 防止取 下墨盒时海绵体处于饱和或过饱和的状态， 防止出现滴墨现象， 并且能保证 经过长途运输后， 用户初次使用填充装置时不会发生溅墨的现象。
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精神和范围。
