本发明涉及一种喷墨打印机墨盒,尤其涉及一种组装式喷墨打印机墨盒。
背景技术
现有的墨盒结构是,拥有容纳墨水的容纳部,也拥有通过连通口吸收并保存墨水的保持体,还设置了向打印机供墨用的供墨口,在打印时打印机内部的载体带动墨盒反复移动过程中,因为剧烈的移动而产生气泡,含有气泡的墨水向打印机供墨时,气泡会使墨水有断线,会导致发生打字褪色的致命问题,为防止打字褪色,用多孔质体(氨甲酸酯海绵或无纺布)吸引并保存墨水,来实现只供给墨水不含气泡,使打印质量得到保证的目的;但是由于在这当中需要使用柔韧性薄膜做成墨盒包装袋,在这其中需要将空气完全排除只充满墨水以防止气泡发生,而多孔质体一般是以有细小的组织组成的海绵为代表,另外无纺布等也被广泛使用,一般被使用的有细小连泡组织组成的材料是氨基甲酸酯,发泡率在50%以下的被广泛使用,而且,因为要被压缩后容纳至容器的原因,就形成了可大量灌装墨水的可能性;将多孔质体装入墨盒后,因为要尽可能的将细小组织最小化的原因而采用压缩容纳,因此在操作上有一定的困难,而且容纳后非均匀排列等原因,所以会造成比较多的不安定因素;目前的压缩容纳多孔质体的微小组织或者是无纺布,为了对吸收过来的墨水有亲和力,而且以没有抵抗的使墨水移动为目的,具有需要事先用界面活性剂等进行前处理的麻烦;具体来说,多孔质体的墨水保持方法是,因为装在海绵组织内的墨水是不可能完全消耗尽的,在有大量墨水的残留的实际状态下而程序有可能会显示墨水已空,为了稳定质量而给终端用户带来不必要的负担,这和节能减排的观点是相反的;而采用压缩装的多孔质体实现[墨水移动原理]的正品制造企业,把[毛细管原理]挂在嘴边,像这样的墨盒制造企业,尽管有30%的墨水残留,依然使终端用户放弃残留墨水显示墨水已空,如果是毛细管力使墨水移动的话,那么他的余量应该是0,所以它不是毛细管力原理而是根据压力的倾斜而使组织内的墨水移动,所以导致有大量残留墨水;另外,采用压缩装的多孔质体的一些产品,将向打印机供墨的出墨口设定的很高,打算将这个部分集中所有压力将墨水吸入,这个被误认为是毛细管力的力不能将墨水吸入上部,而导致了墨水大量残留,如果按照企业所描述的利用毛细管力可以将墨水移动的原理的话,那么墨水从底部向高部流动而且不受压力变动影响的情况下应该是可以移动的,尽管是这样,现有的像这样的产品,因为残留墨水太多功能不稳定而无可奈何的不能被取代,而多孔质体的墨水移动,各细小组织内充满的墨水在打印机内根据消耗情况而使体积减少从而产生的负压,按照顺序连续的向墨水消耗部传播,采用多孔质体的墨水保持体必须要满足向各个细小组织内平均填充墨水的条件,填充装置,多孔质体压缩填充时各个细小组织内整列平均性的不安定因素导致的问题很多,使得现有的产品打印品质也存在了不安定的因素。
而目前被广泛使用的多孔质体,它内部的细小组织为了能让墨水顺利的移动而必须采用前处理工程,而且墨盒容器内压缩容纳作业的难度较大,容纳状态比较零散,填充状态也比较零散,所以导致墨水大量残留打字品质较差等不安定因素;为了维持墨盒的性能,多孔质体内部的细小组织内的空气必须要在抽空的状态下才能注入墨水,这就需要一个比较大的生产设备和生产工时。
发明内容
本发明的目的在于克服现有技术的不足而提供一种不使用多孔质体、将部件数量减少、减少生产工程、提高生产效率、将墨盒的品质安定化、残留墨水减少化、生产成本降低化的划时代的优质墨盒产品,且外壳和墨水盒装配时,不需要任何工具和设备,操作者只需简单操作便可完成两者的装配,最后将装配后的墨盒贴上专用的商标就完成了整个墨盒的制作;像本发明这样的墨盒,两分割体有不同的功能,部品结构简单,功能集中,工时降低,因为生产和装配的容易性,所以品质和效率有大幅度的提高。
为实现上述目的,本发明采用了下述技术方案:
这种组装式喷墨打印机墨盒,包括有独立成型后相互配合的外壳与墨水盒,所述的外壳上设置容置墨水盒的开口,所述的墨水盒设置有存放墨水的墨水容纳部和保证墨水能持续供给的供墨部、为了保证稳定供墨的供墨路线,以及为注入空气而设置的蛇形槽。
所述的墨水盒包括有长方形空间与热熔膜形成的墨水容纳室,以及与该墨水容纳室相通的孔,在长方形空间内设置有供墨的负压发生部,所述的负压发生部包括有墨水存储空间以及设置于其底部的海绵发泡体,所述的墨水盒上设置有一注墨口与墨水存储空间相通,在墨水盒中还设置出墨口以及空气导入口,所述的供墨路线一端与出墨口相通,一端与负压发生部通过墨水流入口在海绵发泡体处相通,所述的空气导入口与蛇形槽通过弧形槽相通,其余空间用来容纳墨水。
所述的墨水盒设置弧形槽的一侧上设置有第一空气导入室和第二空气导入室,所述的第一空气导入室与第二空气导入室之间与墨水盒内壁之间设置有缝隙,所述的第二空气导入室中设置有发泡密度在50%以下的海绵。
所述的出墨口的底部根据墨水的流向采取倾斜的结构,墨水最终会沿着倾斜方向流动。
所述的墨水盒供墨路线的出墨水与墨水流入口之间设置了供墨槽,供墨槽的外侧用热熔接膜构成了一个个微小的空间。
所述的墨水盒上设置供墨槽的同一平面上设置有与空气导入口相通的供压槽,供墨槽的外侧同样用热熔接膜构成了一个个微小的空间。
所述的负压发生部墨水存储空间的内壁直径小于海绵发泡体的外径,负压发生部海绵发泡体处的内壁上设置有供墨水存储空间的墨水下流的由若干凸肋形成的供墨沟,同时在海绵发泡体的下部设置有钢球,所述的钢球与负压发生部的内壁之间设置有密封圈。
所述墨水盒周边设置了外壳与墨水盒装配时调整间隙用的凸起,在突起周围设置了若干个加强锁定外壳与墨水盒装配时的锁定凸起,对应在外壳上设置有若干锁紧槽。
所述的外壳设置有一开口,在该开口的宽度方向的外侧设置有将墨盒与打印机锁定的突起部,该突起部的起点与外壳一体连接,另一端设置有将墨盒顺利安装到打印机上而设置有锁紧肋板,在外壳的长度方向与供墨部配合处设置有突台,该突台与供墨部上的槽配合卡定。
所述的外壳的下方设置有由多个接触点构成的基盘,基盘内部设置有控制操作的IC,在外壳上设置有若干对应将基盘通过热压安装到外壳的突起。
通过上述技术方案,从而该发明具有下述有益效果:
由于使用多孔质体(海绵)少,基本不用,又将部件数量减少,减少了生产工程,提高了生产效率,将墨盒的品质安定化了,残留墨水减少化了,从而该发明的墨盒是一种将生产成本降低化的划时代的优质产品;
且外壳和墨水盒装配时,不需要任何工具和设备,操作者只需简单操作便可完成两者的装配,最后将装配后的墨盒贴上专用的商标就完成了整个墨盒的制作;
像本发明这样的墨盒,两分割体有不同的功能,部品结构简单,功能集中,工时降低,因为生产和装配的容易性,所以品质和效率有大幅度的提高。

具体实施方式
下面结合附图对该发明作出进一步的说明。
如图1-9所示,这种组装式喷墨打印机墨盒,包括有独立成型后相互配合的外壳2与墨水盒3,所述的外壳上设置容置墨水盒的开口9,所述的墨水盒设置有存放墨水的墨水容纳部和保证墨水能持续供给的供墨部6、为了保证稳定供墨的供墨路线7,以及为注入空气而设置的蛇形槽8;所述的墨水盒3包括有长方形空间31与热熔膜42形成的墨水容纳室41,以及与该墨水容纳室相通的孔33,在长方形空间内设置有供墨的负压发生部34,所述的负压发生部34包括有墨水存储空间70以及设置于其底部的海绵发泡体72,所述的墨水盒上设置有一注墨口32与墨水存储空间相通,在墨水盒中还设置出墨口50以及空气导入口60,所述的供墨路线7一端与出墨口50相通,一端与负压发生部通过墨水流入口52在海绵发泡体处相通,所述的空气导入口60与蛇形槽8通过弧形槽47相通,其余空间用来容纳墨水;所述的墨水盒3设置弧形槽47的一侧上设置有第一空气导入室37和第二空气导入室36,所述的第一空气导入室与第二空气导入室之间与墨水盒内壁之间设置有缝隙38,所述的第二空气导入室中设置有发泡密度在50%以下的海绵45;所述的出墨口50的底部35根据墨水的流向采取倾斜的结构,墨水最终会沿着倾斜方向流动;所述的墨水盒3供墨路线7的出墨水50与墨水流入口52之间设置了供墨槽51,供墨槽的外侧用热熔接膜65构成了一个个微小的空间;所述的墨水盒3上设置供墨槽51的同一平面上设置有与空气导入口60相通的供压槽61,供墨槽的外侧同样用热熔接膜65构成了一个个微小的空间;所述的负压发生部34墨水存储空间70的内壁直径小于海绵发泡体72的外径,负压发生部34海绵发泡体处的内壁上设置有供墨水存储空间的墨水下流的由若干凸肋77形成的供墨沟78,同时在海绵发泡体72的下部设置有钢球73,所述的钢球73与负压发生部的内壁之间设置有密封圈74;所述墨水盒3周边设置了外壳与墨水盒装配时调整间隙用的凸起26,在突起周围设置了若干个加强锁定外壳与墨水盒装配时的锁定凸起25,对应在外壳上设置有若干锁紧槽22;所述的外壳设置有一开口9,在该开口的宽度方向的外侧设置有将墨盒与打印机锁定的突起部20,该突起部的起点28与外壳一体连接,另一端设置有将墨盒顺利安装到打印机上而设置有锁紧肋板5,在外壳的长度方向与供墨部6配合处设置有突台27,该突台与供墨部上的槽27A配合卡定;所述的外壳的下方设置有由多个接触点构成的基盘4,基盘内部设置有控制操作的IC,在外壳上设置有若干对应将基盘通过热压安装到外壳的突起10。
具体来说,如图1a、图1b所示,这种墨盒1在外壳2上设置有组成打印机主机和电气控制部的控制基板4,为了确保墨盒能顺利安装在打印机上而设置的锁定功能的5,墨水盒3由墨水容纳部和保证墨水能持续的供给打印机的供墨部6和,为了保证稳定供墨的供墨路线7,为了稳定持续的将墨水送到墨水盒内而设置的注入空气用的蛇形槽8等。
如图2、图3、图4、图5所示,为了将墨水盒3能和外壳2更好的锁紧;将外壳的面设置成具有开口9的长方形,该长方形的宽度方向的外侧有为了更好的将墨盒锁定在打印机上而设置的卡位上的突起部20,这个卡位的起点28和外壳连接而设置成了一体结构,因为有这个突起部所以墨盒能自动的将与打印机锁紧,为了能顺利的将墨盒从打印机上取下,卡位部分的材料尽量减少使卡位的壁变薄,从而提高了韧性;在外壳的下方,为了能让主机和墨盒更好的交换信息,由多个接触点构成了基盘4,内部设置了控制操作用的IC,将基盘固定到外壳的突起10,确定好固定位置后用热压将基盘安装至外壳;墨水盒3组装时的位置确定后,根据正确的精确度将供墨部6的接触部分的形状进行确认,同时自动锁紧部分凸台27和墨水盒3周围的锁紧突起25被配套设置,所以和墨水盒3组装时工具道具设备等都不需要使用只需简单操作就可将墨盒1组装好;外壳2和墨水盒3组装时,墨水盒各个边的外周设置了维持空隙用的凸起26,因为四边都有凸起,所以墨水盒和外壳之间的间隙能自动的保持均匀,同时为了保证外壳和墨水盒的安装状态的锁紧其结构,具体包括有外壳2边上的锁紧槽22和墨水盒3的外周锁紧用的锁紧突起25而组成的,锁紧突起25和保持间隙用的突起部26之间的距离设置为10mm之内,能保证更好的锁紧状态;外壳2和墨水盒3安装时的固定方法是,墨水盒下面设置了一个将墨水送入打印机的供墨部6,这个供墨部的槽27A被外壳2下面设置的锁定用的突台27给包住并锁紧;墨水盒3部分有个长方形空间31,这里设置了供墨的负压发生部34,空气导入口60和连接了和空气连通线路的弧形槽47,其他的空间都用来容纳墨水;长方体31的内侧和第一空气导入室37装入了连泡海绵45,海绵的目的是,当墨水容纳部在有气温的变化和压力的变化的情况下有空气侵入,海绵可以将墨水吸收,阻止墨水从空气导入口流到到墨水容纳室41内;墨水盒的长方形31的开口9,为了构成墨水容纳室在长方形的四周用热熔膜42将长方形封死,同时弧形槽47也被热熔膜封住了,所以内部的空气连通口和墨水就可以在隔离的状态下将空气输入内部;构成墨水盒3的长方体31内的墨水容纳室内部的侧壁上,设置了向负压发生部供墨用的出墨口50,这个出墨口的下面和构成墨水容纳室的长方体31的底面35在同一个面上,在这个容纳室的底面35上设置了为了将墨水向出墨口50移动用的倾斜部,也就是说,底面35设置在出墨口50的最下面,这一点就能确保墨水最后会从墨水容纳室内流出,这里具体的例子是角度为0.3/10的倾斜;在长方体31的外侧面设置有墨水向负压发生部供墨用的供墨槽51,以墨水容纳部和该侧面连通的供墨口50为起点,和组成负压发生部的墨水流入口52为终点组成;如图4所示,在同一面上还设置了,为了向墨水容纳部导入空气用的蛇形的供压槽61,这个空气导入路线的起点是,从在这个侧面上设置的空气导入口60,经过这个侧面连通的墨水盒长方体内侧的弧形槽47到达和外侧连接的蛇形槽61,设置在这个侧面的终点连通口再次通过这个侧面向墨水容纳室流入,在这里还设置了两个小空气导入室第二空气导入室36和第一空气导入室37,这两个小导入室通过很小的缝隙和墨水容纳部连通,空气从蛇形槽进入第二导入室36再进入第一导入室37最后进入墨水容纳部;在导入空气的路线里面,为了防止墨水倒流,采用了将海绵45填满至离墨水容纳室最近的第一空气导入室37的方法,墨水盒在倒置或摇晃的情况下墨水会通过蛇形槽而倒流,因为从本质上来讲防止墨水倒流是不可能的,所以为了将墨水倒流的侵入路线分割开,将第一空气导入室37里面填满海绵,这样的话,在实际使用过程中,即使有墨水侵入的情况,在大气的压力下墨水会被返压回墨水容纳室,所以会防止墨水倒流;在长方体31的侧面设置的供墨线路由出墨口50、供墨槽51、墨水流入口 52组成,因为空气蛇形供压槽61一定要完全密封,所以在这个侧面的外侧需要用热熔接膜65将这两部分进行熔接,虽然这两个部分用一个熔接膜熔接但是他们的作用是分开的,在工作效率方面来讲这个设置方法是非常值得称赞;在使用前,在空气导入口60焊接有手撕膜66,因为顾客在使用前要将这个膜撕掉,所以这个部分用手撕膜66单独熔接,为了将手撕膜撕掉后不会有残留的膜留在空气导入口上,关于熔接面的形状也进行了特别的设置。
如图6、图7、图8、图9所示,负压发生部设置有墨水的储存空间70和能感知墨水的微小消耗的海绵发泡体72,这个海绵发泡体72可以检测出墨水的微小消耗的同时,还有可以辅助钢球73向下移动的功能;将墨盒装入打印机时,钢球73被打印机的墨水吸收管101向上顶,顶高的位置开始到密封圈74的这段空间里充满了墨水,以此向打印机供墨,当墨盒从打印机上取下时,因为墨水吸收管101被拔出,钢球73因为自重会自动落下并和密封圈74紧密接触,因为密封圈74和钢球紧密接触的效果所以防止了墨水滴下而达到了密封的效果。
在使用过程中,将墨盒1安装到打印机时,首先将熔接在空气导入口60的手撕膜66撕掉,然后将墨盒安装至打印机,打印机的墨水吸收管101会穿破墨盒下部的出墨口6上的熔接密封膜76,沿着密封圈74进入负压发生部,墨水吸收管的前端再次持续进入,将钢球73顶到指定位置后停下,因为钢球73被顶到上部,吸收在海绵组织72里面的墨水被挤出,所以墨水吸收管周围就充满了墨水,所以这种结构能向打印机提供充足墨水而不发生打字断线等不良现象;而打印机在消耗墨水的情况下,负压发生部34里的墨水在消耗的同时也会产生压力变化,墨水通过供墨槽51依次由出墨口50通过负压发生进墨口52连续向打印机供墨,进入以确保良好的打印品质。
将墨水注入墨盒的注入方法是,长方体31上面的注墨口32和孔33是非密封状态以外,其他的部分全部为密封状态,注墨口32在负压发生部的延长线上,与墨水存储空间相连接,孔33和墨水容纳室41连接,孔33基本作用为减压,可以使墨盒内部保持高负压状态,而注墨口32是注入墨水用,在减压设定完成之前注墨口32保持密封状态;长方体31内部所要达到的压力值到达以后,将注墨口32的阀门打开,所要的墨量由负压发生部注入,然后墨水沿着墨水流入口52至供墨槽51最后由出墨口50流入墨水容纳部41,为了将负压发生部34内的墨水完全充满,必须要在减压的状态下注入墨水,同时为了保证打印质量,要绝对避免有气泡侵入负压发生部;注墨完成后,用橡胶塞38将注墨口32和孔33封住;为了确保绝对的封闭状态在上面用热熔接膜片67将其熔接,从而在这种情况下墨水盒3内在充满墨水并完全封闭的状态下,能够保持不漏墨的高品质,而墨水盒3的长方体31的结构特别是墨水容纳部41的内部,除了必要的结构外其他的材料都未使用,结构简单降低了生产成本,简化了制造工艺。
由于本发明这种组装式喷墨打印机墨盒,它由墨水容纳室以及向打印机供墨的供墨部和能准确把握墨水的消耗情况、固定打印机的打印品质的固定装置组成,因为从它的结构的内部开始将墨水保持体等附属材料都彻底省略,所以使本墨盒达到工艺最简单,生产工时及成本降低到最极限,从而是一种达到了高品质的优质墨盒;
又由于本发明这种组装式喷墨打印机墨盒采用了功能分开的分割体结构,外壳部分基本不需要进行加工,只要将墨水盒部分进行加工生产,完成了墨水盒部分的加工后直接和外壳进行装配,只要按颜色配置相应的芯片装配到外壳上即可完成整个制品,所以,在生产过程中即使有计划变更等都可以根据这个极其富有弹性的应对性来减少不必要的浪费;
而墨水盒的开口部是由透明的熔接膜密封,所以在生产过程中可以更好的对颜色进行管理,生产时的正确性也值得期待;
同时,墨水容纳室的底部为了促使墨水向出墨口流动而设置了斜面结构,所以墨水能得到完全消耗,不存在不能使用的墨水,所以使用功率极高;
另外,本发明盒外壳部和墨水盒部都可以单独使用,装在打印机上的墨盒内部的墨水盒单独使用也可以,因为这样,所以可以根据颜色先生产墨水盒,再按需要与外壳进行装配就可以完成制品,在生产上有相当的合理性。
