喷墨打印机用墨水容器 技术领域
本发明涉及喷墨打印机用墨水容器，与该墨水容器适配的记录头被设置于 喷墨打印机字车上， 并以可拆卸的方式装配在喷墨打印机字车上， 并通过供墨 针和相应墨水流动通路同记录头上的喷嘴保持连通。 本发明基于申请日为
2007年 2月 24日、 申请号为 200720048947. 5的中国实用新型专利申请， 该 申请的内容作为参考引入本文。 背景技术
喷墨打印机的打印方式通常是由用于容储墨水的墨水容器提供墨源，经由 相应的墨水流动管道将墨水输运至记录头，在打印信号的驱动下将墨水自记录 头上的喷嘴喷射至纸张等记录介质上， 来完成字符或图形的记录。常见的市售 喷墨打印机根据其喷嘴的结构形式，可以分为压电式喷墨打印机和气泡式喷墨 打印机。
压电式喷墨打印机，是在其记录头喷嘴附近的墨水流动管道两侧各设置一 块或多块压电晶体。压电晶体受经过数据调制的打印信号控制， 产生收缩或膨 胀变形， 挤压喷嘴中的墨水自喷嘴射出后形成微细的液滴，溅落至记录介质例 如纸张的页面上， 形成一个记录点。
气泡式喷墨打印机， 其记录头结构与压电式喷墨打印机相似。它们的差别 是，气泡式喷墨打印机在记录头喷嘴附近的墨水流动管道内壁或外壁上设置了 加热电极。数据调制的电脉冲信号被送到喷嘴的加热电极上， 加热电极快速升 温， 使喷嘴附近的墨水迅速汽化， 形成汽泡。汽泡膨胀产生的压力使墨水自喷 嘴射出后形成一个个微细的墨滴， 溅落至纸张页面上。 电脉冲消失后， 墨水蒸 汽凝聚， 喷嘴内的墨水通过表面张力维持在与喷嘴外表面齐口的水平。记录头 抽取墨水后形成的负压引导储墨腔内的墨水流入喷嘴所在的墨水流动管道。
按照记录头同墨水容器的配置关系， 喷墨打印机墨水容器又包括两种类 型。一种是墨水容纳主体（如墨水储藏室）与记录头合一的一体化结构墨水容 器； 另一种是墨水容纳主体与记录头分离的分体式结构墨水容器。一体化结构 的墨水容器既包括记录头也包括墨水储藏室，其记录头设置于墨水容器的出墨 口上。分体式结构的墨水容器， 其墨水储藏室与记录头相互分离设置， 墨水储 藏室仅用于盛装墨水， 记录头则设置于打印机字车上。其中， 分体式结构的墨 水容器又包括纯空腔储墨和多孔材料例如海绵储墨两种形式的墨水容器。
分体式纯空腔无海绵结构形式的墨水容器，通常需要在其导气口设置用于 调节墨水容器内腔压力和外部环境之间平衡状态的单向开闭的气体控制阀，以 避免墨水从导气口溢出到墨水容器外部，同时还会在出墨口上游的墨水流动管 道上设置单向启闭的墨水控制阀。这种墨水容器一则因为配设气体控制阀和墨 水控制阀而导致墨水容器结构较为复杂， 且在墨水容器遭遇翻转、倾侧、振动 和 /或温变的情况下， 墨水容器内部不受墨水控制阀影响的各腔室之间将会由 于其内气体同墨水混融成细碎的气泡，而出现气体在各腔室之间不规则游走的 现象。这些游动气泡一旦进入墨水容器出墨口， 就有可能顺着喷墨打印机供墨 针游动到纪录头的喷嘴上， 以致形成记录字迹断线、 无墨等。 发明内容
本发明目的在于提供一种喷墨打印机用墨水容器， 该墨水容器结构简单， 且在储运过程中即使墨水容器出现翻转、倾侧、振动或温度变化的情形， 也能 够防止储墨腔和 /或换气腔中的气体随墨水流入到出墨口中。

实施例一
下面结合附图详细描述本发明喷墨打印机用墨水容器。在所有附图中， 相 同的标记将被用来指代相同的零部件、特征或者结构。实施例介绍过程中所针 对的具体结构或零部件仅作为本领域技术人员理解依据本发明的墨水容器的 参考性例证，本领域技术人员在实施例的启示下还可以设计出不超出该墨水容 器技术范围和实质的各种等同或类似的技术构造。 由此， 如果用这种示例性说 明来限制本发明喷墨打印机用墨水容器权利要求所囊括的保护范围是不适宜 的，等同或类似于本发明喷墨打印机用墨水容器的技术方案仍然属于本发明喷 墨打印机用墨水容器权利要求的保护范围。
参见图 1、 2、 3、 4， 作为本发明实施例一的结构图， 图 1、 2、 3、 4所示 喷墨打印机用墨水容器 A具有相同于安装到喷墨打印机上的姿态，即其出墨口 105和出墨口 105中的墨水流动方向朝向水平方向， 而盒盖 2则位于盒体 1的 侧部。 为便于描述， 以图 1、 2、 3、 4所示喷墨打印机用墨水容器 A的放置姿 态作为参照系，该墨水容器 A的各构成部件或构成要素之间具有如下描述的配 置协调关系。
图 1中，该墨水容器 A组成构件包括采用塑料等原材料以注塑形式制备的 盒体 1和盒盖 2。 盒盖 2可以视为盒体 1的一个可以活动的侧壁。 在盒体 1内 通过设置相应的多个隔板，将盒体 1分隔出多个空腔。盒盖 2通过胶水粘接方 式或者直接熔化粘接的方式被固定于盒体 1上之后，使前述空腔成为可以容纳 墨水的密闭容器。
参见图 2、 3、 4， 盒体 1通过采用前述隔板分隔措施后， 在盒体 1上形成 供墨腔 100和第一储墨腔 101。
其中，在作为供墨腔 100的构成件且平行于铅垂方向的侧壁 106上，接近 供墨腔 100沿铅垂方向的底壁 107的部位设置有出墨口 105。 出墨口 105连通 供墨腔 100和外部环境。在供墨腔 100容储有墨水的情形， 出墨口 105通常被 胶圈密封阀 102密封。在墨水容器 A被安装到喷墨打印机上的状态下， 记录头 上的供墨针穿过胶圈密封阀 102中部的缝隙 104而进入出墨口 105内，以抽取 供墨腔 100中的墨水。出墨口 105及出墨口 105中的墨水流动方向平行于水平 方向。在供墨腔 100内沿铅垂方向的中央位置以上的部位， 设置有呈水平布置 的第一导墨管 110。第一导墨管 110的轴线方向垂直于出墨口 105内的墨水流 动方向。 第一导墨管 110的径向尺寸选择为 0. 5mm〜1. 2mm范围内的任一具体 数值， 以较为有利地阻止空气在其内形成无阻碍的自由流动， 第一导墨管 110 的长度接近供墨腔 100同第一导墨管 110所在位置重合之部位的宽度。确切地 说第一导墨管 110基本上跨接供墨腔 100距离最短的两个腔壁。 第一导墨管 110的一端连通供墨腔 100， 其另一端通过在盒体 1外壁上开设的由密封膜封 闭的第一输墨槽 111， 在第一储墨腔 101沿铅垂方向低于第一导墨管 110且同 时也是第一储墨腔 101铅垂方向最低的位置上所设置的第一连通孔 112连通第 一储墨腔 101。 这里， 第一连通孔 112位于第一储墨腔 101铅垂方向最低的位 置， 是指第一连通孔 112位置接近墨腔底壁 107， 其主要目的是在第一储墨腔 101铅垂方向的最低部位抽取第一储墨腔 101中的墨水， 以充分利用其中容纳 的全部墨水， 避免形成墨水残留。
第一储墨腔 101在自身铅垂方向的最高部位通过第二连通孔 113， 连通位 于盒体 1相对于侧壁 106的另一侧壁 114外表面上的导气口 115。 导气口 115 连通外部大气。在导气口 115和第二连通孔 113之间， 于盒体侧壁 114外表面 上增加设置了一段较长的迷宫式不规则管槽或称蛇形管槽 116。 蛇形管槽 116 通常采用塑料薄膜或者铝箔密封后形成封闭的气体流动管路。 因此， 导气口 115和第二连通孔 113之间通过蛇形管槽 116相互连通。这里，第二连通孔 113 位于第一储墨腔 101铅垂方向的最高部位具有相对的含义，即根据额定的墨水 储量或者设计储量， 第二连通孔 113只要高出第一储墨腔 101中的墨水液面， 那么在打印过程中由于墨水容器 A 因喷墨打印机供墨针抽取墨水后在其中形 成了由第一储墨腔 101至供墨腔 100再到出墨口 105的墨水流动线路，就可以 避免第一储墨腔 101中的墨水沿第二连通孔 113倒灌至导气口 115， 也就是说 第二连通孔 113位于第一储墨腔 101铅垂方向较高部位的构思也是可行的。
在侧壁 106上邻近供墨腔 100 的部位， 设置有在水平方向较供墨腔 100 更为扁的检测腔 103， 其与侧壁 106平行的外壁由一贴膜构成， 另一对相互平 行的壁由透光材料制成， 当然， 也可以是盒体 1 就用透光塑料制造。 检测腔 103中置放有浮标 129 (参见图 4)。在检测腔 103充满墨水的状态下，浮标 129 漂浮于墨水的液面上。检测腔 103通过开设于其铅垂方向上部腔壁和下部腔壁 上的上部通孔 108和下部通孔 109同供墨腔 100保持连通。检测腔 103在铅垂 方向上整体位于供墨腔 100的最高部位和最低部位之间。 因此， 在供墨腔 100 容储的墨水液位高出检测腔 103铅垂方向上部通孔 108的状态下， 检测腔 103 即可处于充满墨水的状态， 浮标 129即可悬浮于检测腔 103内的墨水中。随着 检测腔 103内墨水随打印消耗状态的变化，浮标 129的位置沿检测腔 103铅垂 方向逐歩下移。浮标 129的这种位置变化同喷墨打印机上设置的光电检测机构 配合， 就可以获取供墨腔 100内的墨水容储信息。
实施例二
参见图 5， 并参阅实施例一附图， 出于防止气液交换后过量气体进入供墨 腔 100， 以致影响检测腔 103内浮标 129的浮沉环境， 以及从出墨口 105输出 的墨水的纯净度，本实施方式在实施例一的基础上对墨水容器 A的结构作出了 如下调整。一则压缩了第一储墨腔 101的容积， 二则在墨水容器 A内部添设了 第二储墨腔 117。 经过这种改造后， 本实施方式较之实施例一， 既具有相同于 实施例一的技术特征， 又产生了自身的结构特点。 出于行文简明的需要， 这里 省略了对本实施方式中相同于实施例一的技术特征的描述，对此， 本领域技术 人员可以参照前述实施例一的介绍，转而详细介绍实施例二不同于实施例一的 方面。本实施方式中相同于实施例一的技术特征仍然采用同实施例一附图相同 的标记， 不同的技术特征则采用不同于实施例一附图的新标记号。
在本实施例中， 墨水容器 A在设置两个储墨腔， 即第一储墨腔 101和第二 储墨腔 117之后，继续保留供墨腔 100同第一储墨腔 101之间通过第一导墨管 110连通的构造关系， 而第一储墨腔 101同墨腔底壁 107之间的关系则被做出 相应调整，即第一储墨腔 101容积压缩后其底壁由墨水容器 A内部的相应隔板 取代，第一连通孔 112的位置对应地向上移动一段距离， 同时存在于实施例一 中的技术特征一一 "第一储墨腔 101在自身铅垂方向的最高部位通过第二连通 孔 113 连通位于盒体 1 相对于侧壁 106 的另一侧壁 114外表面上的导气口 115"， 则被下述技术特点取代。
见图 5 (并结合图 8所示）， 在第一储墨腔 101沿铅垂方向的最高部位， 设 置有呈水平布置的第二导墨管 118。 第二导墨管 118 的一端连通第一储墨腔 101， 其另一端通过在盒体 1外壁上开设的由密封膜封闭的第二输墨槽 119， 在第二储墨腔 117沿铅垂方向低于第二导墨管 118且同时也是第二储墨腔 117 铅垂方向最低的位置上所设置的第三连通孔 120连通第二储墨腔 117。第二储 墨腔 117在自身铅垂方向的最高部位通过第二连通孔 113， 连通位于盒体 1相 对于侧壁 106的另一侧壁 114外表面上的导气口 115。
实施例三
本实施例是在实施例二基础上进一歩改造获得的技术方案，其技术特征的 调整情形类似于实施例二。 因此， 出于同实施例二一样的缘由， 不再赘述本实 施例改造前的技术基础， 请参阅实施例一和实施例二的介绍。这里仅描述本实 施例的结构特点。
参见图 6所示 （并结合图 8所示）， 在实施例二基础上， 本实施例在墨水 容器 A内部添设了第三储墨腔 121。 墨水容器 A在设置三个储墨腔， 即第一储 墨腔 101、 第二储墨腔 117和第三储墨腔 121之后， 继续保留第一储墨腔 101 同第二储墨腔 117之间通过第二导墨管 118连通的构造关系，而存在于实施例 二中的技术特征—— "第二储墨腔 117在自身铅垂方向的最高部位通过第二连 通孔 113， 连通位于盒体 1相对于侧壁 106的另一侧壁 114外表面上的导气口 115"， 则被下述技术特点取代。
在第二储墨腔 117沿铅垂方向的最高部位，设置有呈水平布置的第三导墨 管 122。 第三导墨管 122的一端连通第二储墨腔 117， 其另一端通过在盒体 1 外壁上开设的由密封膜封闭的第三输墨槽 123， 在第三储墨腔 121沿铅垂方向 低于第三导墨管 122且同时也是第三储墨腔 121铅垂方向最低的位置上所设置 的第四连通孔 124连通第三储墨腔 121。第三储墨腔 121在自身铅垂方向的最 高部位通过第二连通孔 113， 连通位于盒体 1相对于侧壁 106的另一侧壁 114 外表面上的导气口 115。
实施例四
本实施例是在实施例三基础上改造获得的技术方案，其技术特征的调整情 形类似于实施例三。 因此， 不再赘述重复内容， 仅描述本实施例结构特点。
见图 7 (并结合图 8所示）， 在实施例三基础上， 本实施例在墨水容器 A 内部添设了换气腔 125。 墨水容器 A在加设置换气腔 125之后， 继续保留第二 储墨腔 117和第三储墨腔 121之间通过第三导墨管 122连通的构造关系，而存 在于实施例三中的技术特征一一 "第三储墨腔 121在自身铅垂方向的最高部位 通过第二连通孔 113， 连通位于盒体 1相对于侧壁 106的另一侧壁 114外表面 上的导气口 115 "， 则被下述技术特点取代。
在第三储墨腔 121沿铅垂方向最高部位，设置有呈水平布置的第四导墨管 126。 第四导墨管 126的一端连通第三储墨腔 121， 其另一端通过在盒体 1外 壁上开设的由密封膜封闭的第四输墨槽 127， 在换气腔 125沿铅垂方向低于第 四导墨管 126且同时也是换气腔 125铅垂方向最低的位置上所设置的第五连通 孔 128连通换气腔 125。换气腔 125在自身铅垂方向的最高部位通过第二连通 孔 113，连通位于盒体 1相对于侧壁 106的另一侧壁 114外表面上的导气口 115。 工业应用性
本发明墨水容器，在各墨腔之间采用具有一定长度和一定径向尺寸的水平 导墨管作为它们相互连通的墨水管路，同时对导墨管连通各墨腔的端口赋予铅 垂方向上不同的位置，使墨水容器在初次灌墨或回收灌墨并封闭出墨口和导气 口之后的储运过程中， 其内各墨腔之间无论墨水容器处于正立、侧置、 倒立或 者翻转的任何状态都能通过导墨管或者其相应端口之至少一个被浸没于墨水 中而保持气体在各墨腔之间不发生交换的状态。如此，在保持出墨口和导气口 被封闭的储运状态下， 该墨水容器不仅能够有效地防止储墨腔和 /或换气腔中 的气体随墨水流入到出墨口或连通出墨口的供墨腔中，而且实现阻止气体交换 的技术措施仅仅是导墨管和其端口所处的位置， 因此， 其结构简单。
