参考图1-6，根据本发明的实施例的液体容纳容器10，包括液体收容部100、液体注入口200和呈长圆形、长方形或椭圆形的液体流出口300，液体收容部100包括具有顶壁、侧壁和底壁的外壳110，侧壁包括前端侧壁和后端侧壁，顶壁与前端侧壁和后端侧壁交叉，外壳110内设有收容液体的收容腔，收容腔内设有一隔板114， 隔板114将收容腔划分为储墨腔111和吸液芯腔，隔板114上设有供墨通道，储墨腔111通过供墨通道向吸液芯腔供墨，吸液芯腔包括气液交换腔112和供墨腔113，储墨腔111位于吸液芯腔的一侧，供墨腔113位于气液交换腔112的底部，气液交换腔112和供墨腔113均为柱体式结构，且两个柱体的底面相同；液体注入口200位于液体收容部100的顶壁，液体注入口200距离后端侧壁比距离前端侧壁更近，用于向储墨腔111注入液体(例如墨水)；液体流出口300位于供墨腔113的底部，用于将液体供给至消耗液体的液体消耗装置(图中未示出)，液体流出口300的下部具有两条从液体流出口300的侧壁向液体流出口300的中心径向延伸的支撑折边310，支撑折边310用于对气液交换腔112和供墨腔113内已吸收液体的吸液芯400进行支撑，吸液芯400是毛细管媒体，其能够由纤维状材料(例如毛毡材料)或者烧结材料(例如烧结塑料)制成，例如海绵或者棉芯。
根据本发明实施例的液体容纳容器10，至少具有如下有益效果：将气液交换腔112和供墨腔113均设置为柱体式结构，且两个柱体的底面相同，结构简单，成本降低，也使液体容纳容器10的开发模具制造成本降低，这样的设置方式能够将气液交换腔112的体积缩小却仍能安装大体积的吸液芯400，从而保持一定负压，且提高了储墨量和避免使用异形吸液芯400，同时，位于气液交换腔112和供墨腔113内的吸液芯400可同侧安装，降低了装配复杂度，又保证装配后的吸液芯400与所在腔体的腔壁全面贴合，降低了吸液芯400接合不良的风险。通过在液体流出口300设有支撑折边310，以对已吸收液体的吸液芯 400进行支撑，防止已吸收液体的吸液芯400在液体流出口300脱落，同时位于液体流出口300中心处的吸液芯400远离液体流出口300侧壁，避免吸液芯400夹在液体流出口300侧壁与液体消耗装置的密封垫之间造成的密封不良。
需要说明的是，参见图6，支撑折边310也可以是1条、3条，4条，其具体数量、具体形状和大小，在此不做具体限制，只要支撑折边310能够对气液交换腔112和供墨腔113内已吸收液体的吸液芯400进行支撑，防止已吸收液体的吸液芯400在液体流出口300脱落即可。
在本发明的一些具体实施例中，如图6所示，相邻的两条支撑折边310沿着其延伸方向的长度不相等，结构合理化，外观更美观。
在本发明的一些具体实施例中，如图6所示，支撑折边310首尾相连以形成环形，避免划伤吸液芯和液体消耗装置的过滤装置。
在本发明的一些具体实施例中，如图1‐3所示，液体流出口300从外壳110的底壁向下延伸以形成具有一定高度H的外边圈320，高度H≥3毫米且高度H≤10毫米，扩大供墨腔的体积，从而扩大吸液芯的体积，提高液体容纳容器10的负压能力。
在本发明的一些具体实施例中，如图2‐3所示，气液交换腔112和供墨腔113为一体式结构，结构简单，便于制造，降低加工成本，也使液体容纳容器10的开发模具制造成本降低。
在本发明的一些具体实施例中，如图5‐6所示，柱体为四方柱， 便于制造，降低加工成本，也使液体容纳容器10的开发模具制造成本降低。
在本发明的一些具体实施例中，如图5所示，供墨通道设置在隔板114中间，呈T字型通道，T字型通道的面积与隔板的面积的比例可根据实际需要进行调整，通过调整吸液芯的吸附性和上述比例，可以保证液体流出口不会出现漏墨不良的情形。
在本发明的一些具体实施例中，供墨通道为设置在隔板114上的多个排列的通孔，通孔的排列方式和通孔的形状有多种，只要易于实现且能满足出墨要求即可，通孔设计的个数和通孔的大小可根据实际需要确定，以保证储墨腔111向吸液芯腔充足稳定地供墨。
根据本发明的第二方面实施例的液体容纳单元，如图3所示，包括本发明上述第一方面实施例的液体容纳容器10、第一吸液芯410和第二吸液芯420；第一吸液芯410安装于液体容纳容器10的气液交换腔112内；第二吸液芯420安装于液体容纳容器10的供墨腔113内。
根据本发明实施例的液体容纳单元，至少具有如下有益效果：将液体容纳容器10的气液交换腔112和供墨腔113均设置为柱体式结构，且两个柱体的底面相同，结构简单，成本降低，也使液体容纳容器10的开发模具制造成本降低，这样的设置方式能够将气液交换腔112的体积缩小却仍能安装大体积的吸液芯400，从而保持一定负压，且提高了储墨量和避免使用异形吸液芯400，同时，位于气液交换腔112和供墨腔113内的吸液芯400可同侧安装，降低了装配复杂度，又保证 装配后的吸液芯400与所在腔体的腔壁全面贴合，降低了吸液芯400接合不良的风险。通过在液体流出口300设有支撑折边310，以对已吸收液体的吸液芯400进行支撑，防止已吸收液体的吸液芯400在液体流出口300脱落，同时位于液体流出口300中心处的第二吸液芯420远离液体流出口300侧壁，避免第二吸液芯420夹在液体流出口300侧壁与液体消耗装置的密封垫之间造成的密封不良。
在本发明的一些具体实施例中，如图3所示，第一吸液芯410和第二吸液芯420为一体式结构，中间不存在接缝，避免因第一吸液芯410和第二吸液芯420装配不良时接缝处有气体空间的存在，气体进入液体消耗装置的喷头引起断线，安装第一吸液芯410的同时即完成了第二吸液芯420的安装，减少了装配工序，提高了装配效率和装配良品率。
根据本发明的第三方面实施例的液体供给系统，包括本发明上述第二方面实施例的液体容纳单元和液体消耗装置。
根据本发明实施例的液体供给系统，至少具有如下有益效果：将液体容纳容器10的气液交换腔112和供墨腔113均设置为柱体式结构，且两个柱体的底面相同，结构简单，成本降低，也使液体容纳容器10的开发模具制造成本降低，这样的设置方式能够将气液交换腔112的体积缩小却仍能安装大体积的吸液芯400，从而保持一定负压，且提高了储墨量和避免使用异形吸液芯400，同时，位于气液交换腔112和供墨腔113内的吸液芯400可同侧安装，降低了装配复杂度，又保证装配后的吸液芯400与所在腔体的腔壁全面贴合，降低了吸液 芯400接合不良的风险。通过在液体流出口300设有支撑折边310，以对已吸收液体的吸液芯400进行支撑，防止已吸收液体的吸液芯400在液体流出口300脱落，同时位于液体流出口300中心处第二吸液芯420远离液体流出口300侧壁，避免第二吸液芯420夹在液体流出口300侧壁与液体消耗装置的密封垫之间造成的密封不良。此外，支撑折边310与液体消耗装置的取墨口处的垫圈密封配合，有助于防止空气进入液体消耗装置内，因为气泡能阻塞小的墨水通路中的墨水流动，从而降低打印质量。
在本发明的一些具体实施例中，液体容纳容器10的液体流出口有效面积约等于或者略大于液体消耗装置的取墨口有效面积，减小液体容纳容器10的液体流出口与液体消耗装置的取墨口间形成的密封空间。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少两个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本发明的实施例，本领域的普通技术人员可以理解：在不脱离本发明的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由权利要求及其等 同物限定。
