一种喷墨打印机用二级墨盒
相关申请的交叉引用
本申请要求享有于2021年12月08日提交的名称为“一种喷墨打印机用二级墨盒”的中国专利申请CN202111494751.X的优先权，上述申请的全部内容通过引用并入本文中。
技术领域
本发明涉及喷墨打印设备技术领域，具体涉及一种喷墨打印机用二级墨盒。
背景技术
喷墨打印机的打印小车上安装有二级墨盒，二级墨盒也称为副墨盒。墨水从主墨盒流入二级墨盒，再由二级墨盒将墨水供给各喷头。为了保证墨水的正常供给，二级墨盒上常设置有液位传感器，用于检测墨盒中的墨量，从而可以在墨盒缺墨时及时供给或墨量足够时停止供墨；二级墨盒的墨腔中也需接入负压系统和正压系统，负压系统用于调节墨腔中的负压值，以保证喷头的正常供墨，正压系统用于喷孔堵塞时对喷头进行压墨以疏通喷孔。
在打印颜料墨水时，由于颜料墨水中含有微小的颗粒物，容易在二级墨盒或其他元器件中产生沉淀物，导致墨管或元器件进出墨口的堵塞，更严重的会导致喷头的堵塞，造成的损失较大。墨水由主墨罐供入二级墨盒时，墨水流经各元器件时会混有气泡，气泡容易导致打印喷头的空喷，所以需要对进入二级墨盒的墨水进行脱气处理。中国专利CN206394248U公开的现有技术中采用主墨罐、除气泡装置、第一副墨盒、喷头、第二副墨盒、主墨罐依次连接使得墨水循环流动的大循环方式，由于墨水的流经路程较长，途径各种泵、阀等元器件，容易导致墨水的污染，不仅使得为墨水流动提供动力的装置的功率高，耗费大，而且墨水在长路径的循环流动中更容易受到污染或产生气泡，导致墨水的循环作用效果不理想，而且缩短过滤器等元器件的使用寿命；并且二级墨盒与喷头之间通过泵的作用实现循环，泵在工作时会产生脉冲振动，导致喷头处的墨水循环压力不稳定，影响喷头的打印。
喷墨打印机在正常工作时，对墨水的工作温度有较高的要求，墨水的工作温度一般在23～26℃，当温度过高时，墨水容易挥发导致墨水易干结，当温度过低时，墨水的流动性变差，这两种情况均会造成喷头出墨变差，影响打印质量，因此，二级墨盒供给打印喷头的墨水需保持合适的温度以保持良好的流动性。中国专利CN202088668U公开的现有技术中，虽然可以控制二级墨盒中的墨水的温度在恒定的范围内，但是在二级墨盒的周围设置冷却组件、散热组件和加热组件，增加了二级墨盒的体积和重量，当打印所需的墨水种类较多时，需要安装多个二级墨盒，这会使得喷头小车整体的体积和重量增加，影响小车运动的稳定性，进而影响打印质量；在实际打印工作中，喷头内的墨水温度与二级墨盒内的墨水的温度也会存在一定的温差，二级墨盒中的墨水在合适的温度时，往往打印喷头内的墨水的温度并不在合适的温度范围内，从而影响打印质量。
此外，若二级墨盒墨腔内的液位传感器出现故障，容易导致墨水倒吸至负压通路中，导致负压通路中元器件的损坏，因此，采用负压调节二级墨盒墨腔中的压力值时还需考虑墨水倒吸的问题。
综上，现有技术中存在如下问题：
1)墨水循环路径较长，容易收到污染或二次产生气泡，导致循环效果不理想，并且影响元器件的寿命；
2)二级墨盒与喷头之间通过泵的作用实现循环，泵在工作时会产生脉冲振动，导致喷头处的墨水循环压力不稳定，影响喷头的打印；
3)二级墨盒的恒温装置不仅增加了二级墨盒的体积和重量，且对墨水的恒温效果不理想；
4)需要防止墨水倒吸至负压通路中。

具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。
实施例1：
参照图1和图2所示，一种喷墨打印机用二级墨盒，其改进之处在于：包括墨盒体1、分别与所述墨盒体1相互密封盖合的后端盖2和前端盖3，所述墨盒体1内设有分别位于其左右两侧的供墨腔11和回流墨腔12，所述供墨腔11和所述回流墨腔12的底部分别设有若干通墨孔，所述供墨腔11和所述回流墨腔12内分别设有用于检测墨腔内墨量的液位传感器，所述供墨腔11的上方设有与其相连通的负压腔I13，所述回流墨腔12的上方设有与其相连通的负压腔II14。
本实施例中，打印模块的底部安装有打印喷头，二级墨盒安装于打印喷头的上方，供墨腔11和回流墨腔12的底部分别设有若干通墨孔，供墨腔11通过下端的通墨孔与打印喷头的进墨孔相连通，回流墨腔12通过下端的通墨孔与打印喷头的出墨孔相连通，则供墨腔11、打印喷头、回流墨腔12之间形成了通路。设置负压腔I13内的真空度小于负压腔II14内的真空度，使得负压腔II14和负压腔I13之间形成压力差，墨水进入打印喷头后，一部分墨水由打印喷头喷射至打印介质上，一部分墨水在负压作用下由打印喷头的出墨孔回流至回流墨腔12中，即供墨腔11内的墨水一部分被用于打印，一部分进行了二级墨盒与打印喷头之间的循环，保证了墨水的循环流动，避免墨水产生沉淀物而堵塞喷头，并且循环流程短，减少墨水在循环流动过程中的污染及产生气泡的可能性。二级墨盒与打印喷头之间的墨水循环由两个负压腔内的压力差来产生循环动力，取代了现有技术中通过泵提供循环动力的方式，避免了泵的脉冲振动对喷头打印的影响，提高了打印的稳定性。负压腔I13和负压腔II14的设置，一方面可产生压力差为墨水循环提供动力，另一方面，当供墨腔或回流墨腔中 的液位传感器出现故障导致墨水过多溢出时，负压腔还可作为溢墨墨腔起到缓冲作用，避免墨水倒吸至负压通道中导致元器件的损坏。
进一步的，所述负压腔I13内设有压力传感器I，所述负压腔II14内设有压力传感器II。
进一步的，所述压力传感器I和压力传感器II安装于所述前端盖3上。
实施例2：
在实施例1的基础上，所述回流墨腔12与打印机的主墨罐相连通，所述回流墨腔12与脱气装置的一端相连通，所述脱气装置的另一端与所述供墨腔11相连通。
本实施例中，主墨罐的墨水通过泵不断的泵入回流墨腔12中，由主墨罐泵入回流墨腔12中的墨水不可避免的掺杂有气泡，掺有气泡的墨水进入打印喷头，在进行打印时容易产生空喷的现象，影响打印质量，因此在回流墨腔12和供墨腔11之间设置另一个循环通路，此循环通路用于去除进入供墨腔11内的墨水中的气泡，即回流墨腔12中的墨水在泵的作用下流至脱气装置中，经脱气装置脱气后进入供墨腔11中，保证了供墨腔11供给打印喷头的墨水的质量。
实施例3：
在实施例2的基础上，参照图3至图8所示，所述回流墨腔12内的液位传感器包括低液位传感器II204和高液位传感器II205。
进一步的，所述低液位传感器II204和高液位传感器II205安装于所述后端盖2上并置于所述回流墨腔12内。
进一步的，所述回流墨腔12内设有墨管II5，所述墨管II5安装于所述前端盖3和后端盖2之间、与所述前端盖3相互垂直且高度低于所述低液位传感器II204，参照图11所示，所述墨管II5的底部设有若干通孔II。
进一步的，所述前端盖3的外侧安装有进墨接头I301，所述前端盖3的内侧设有进墨孔311，所述进墨孔311与所述进墨接头I301相连通，所述墨管II5安装于所述进墨孔311内，且所述进墨孔311的直径大于所述墨管II5的直径。
进一步的，所述前端盖3的外侧安装有出墨接头302，所述出墨接头302 与所述墨管II5相连通，参照图10所示，所述墨管II5靠近所述进墨孔311的一端部的上端设有若干通孔III。
进一步的，所述墨管II5的底部远离所述进墨孔311端的所述通孔II之间的间隔小于靠近所述进墨孔311端的通孔II之间的间隔。
进一步的，所述供墨腔11内的液位传感器包括低液位传感器I201、中液位传感器202和高液位传感器I203。
进一步的，所述低液位传感器I201、中液位传感器202和高液位传感器I203安装于所述后端盖2上并置于所述供墨腔11内。
进一步的，所述供墨腔11内设有墨管I4，所述墨管I4安装于所述前端盖3和后端盖2之间、与所述前端盖3相互垂直且高度低于所述低液位传感器I201，参照图9所示，所述墨管I4上设有若干左右贯穿的通孔I。
进一步的，所述前端盖3的外侧安装有进墨接头II303，所述前端盖3的内侧设有墨管安装孔II312，所述墨管I4的一端安装于所述墨管安装孔II312内并与所述进墨接头II303相连通。
进一步的，所述墨管I4上远离所述墨管安装孔II312端的所述通孔I之间的间隔小于靠近所述墨管安装孔II312端的通孔I之间的间隔。
本实施例中，回流墨腔12中的低液位传感器II204保证回流墨腔12中的墨量始终保持在合适的高度，高液位传感器II205用于避免墨量过多而导致溢墨，墨管II5的位置低于低液位传感器，保证墨管II5始终置于墨水中。主墨罐中的墨水从进墨接头I处经过进墨孔311进入至回流墨腔12中，回流墨腔12中的墨水在泵的作用下，由墨管II5底部的通孔II和墨管II5靠近进墨孔311的一端的上端的通孔III进入墨管II5中，并在泵的作用下由出墨接头302流出进入脱气装置中，通孔II之所以设置在墨罐II5的底部，因墨水在墨腔的底端容易产生沉淀，则从底部向上吸入墨水可以使墨腔底部的墨水流动起来，更好的避免产生沉淀，靠近进墨孔311的一端的墨管II5上的通孔III之所以设置在上端，因进墨孔311处的墨水是由主墨罐泵入的墨水，因此气泡含量较高，而含有气泡的墨水质量较轻，一般处于上方，通孔III的设置便于将气泡含量较高的墨水抽进脱气装置中进行脱气，使得脱气效果更好。墨水经过脱气装置 脱气处理后，由进墨接头303进入并通过墨管I4两侧的通孔I流出，供墨腔11内的低液位传感器I201保证供墨腔II内的最低墨量，防止墨量压空，导致打印喷头无墨可喷，中液位传感器用于保证供墨腔11中的墨量始终保持在合适的高度，高液位传感器I203用于避免墨量过多而导致溢墨，墨管I4的位置低于低液位传感器I201，则保证墨管I4始终置于墨水中，避免墨水从通孔I处流出时产生气泡。
墨管I4上的通孔I和墨管II5上的通孔II均是靠近前端盖3的一侧间隔相对于靠近后端盖2的一侧较稀疏，目的是使墨水从进墨孔311的远端被更多的抽走，更增强墨水的流动性，避免沉淀的产生。
进一步的，所述后端盖2内侧设有墨管安装孔I211，所述墨管I4和墨管II5的另一端分别安装于所述墨管安装孔I211内。
进一步的，所述前端盖3的内侧设有分别与所述墨盒体1的供墨腔11、回流墨腔12、负压腔I13、负压腔II14相匹配的凸台，供墨腔11、回流墨腔12、负压腔I13、负压腔II14的外围与所述前端盖3之间分别设有密封圈。
进一步的，所述后端盖2的内侧设有分别与所述墨盒体1的供墨腔11、回流墨腔12、负压腔I13、负压腔II14相匹配的凸台，供墨腔11、回流墨腔12、负压腔I13、负压腔II14的外围与所述后端盖2之间分别设有密封圈。
凸台和密封圈的设置使得墨盒体1与前端盖3和后端盖2之间的密封效果更好。
实施例4：
在上述任一实施例的基础上，所述供墨腔11与所述回流墨腔12之间设有恒温水腔，所述恒温水腔与恒温水系统相连通。
本实施例中，恒温水腔的设置用于调节供墨腔11和回流墨腔12中墨水的温度，使得供给打印喷头的墨水具有良好的流动性。
实施例5：
在实施例4的基础上，所述恒温水腔包括位于所述供墨腔11右侧的水腔I15和位于所述回流墨腔12左侧的水腔II16，所述水腔I15与所述水腔II16之间设有隔离腔17。
进一步的，所述前端盖3的外侧安装有进水接头306，所述进水接头306一端与所述水腔I15相连通、另一端与恒温水系统的出水口相连通，所述前端盖3的外侧安装有出水接头307，所述出水接头307的一端与所述水腔II16相连通、另一端与恒温水系统的进水口相连通，所述水腔I15和所述水腔II16靠近所述后端盖2一端的底部分别设有通水口。
本实施例中，主墨罐中的墨水供入回流墨腔12中，供墨腔11中的墨水供给打印喷头，供墨腔11中的墨水经打印喷头打印后，其余墨水回流至回流墨腔12中，显然回流墨腔12中的墨水温度会低于供墨腔11中的温度，将恒温水腔分为水腔I15和水腔II16，并在其之间设置隔离腔17，避免水腔I15与水腔II16中水温的相互影响，能更好的保证供墨腔11中墨水的处于恒定的温度中，以使供给打印喷头的墨水具有良好的流动性。恒温水系统中的恒温水进入水腔I15后对供墨腔11中的墨水进行温度调节，水腔I15下端的通水口通过水管与水腔II16下端的通水口相连通，水腔I15中的水通过水管回流至水腔II16中，并通过出水接头307流出至恒温水系统中，形成循环水路，用于保证供给打印喷头的墨水具有良好的流动性。
实施例6：
在实施例5的基础上，所述前端盖3的下端安装有水循环接头I310，所述水循环接头I310与所述水腔I15相连通，所述后端盖2的下端安装有水循环接头II210，所述水循环接头II210与所述水腔II16相连通。
本实施例中，安装打印喷头的底板上布设有水管，水腔I15中的恒温水通过水循环接头I310向下分流至底板上的水管中，用于调节底板的温度，以使安装于底板上的打印喷头的周围环境处于合适的温度中，更能保证打印喷头中墨水的良好的流动性，提高打印质量。
实施例7：
在实施例5或6的基础上，所述隔离腔17的上方设有与其相连通的正压腔18，所述隔离腔17用于容置清洗液，所述隔离腔17的底部设有若干通液孔，所述隔离腔17内设有液位传感器，所述液位传感器包括低液位传感器III208和高液位传感器III209。
进一步的，所述前端盖3的外侧安装有清洗液接头309，所述清洗液接头309与所述隔离腔17相连通。
本实施例中，隔离腔17中容置清洗液并通过通液孔与打印喷头相连通，当打印喷头出现堵塞或需要清洗时，通过正压腔18向隔离腔17中施加正压，以将清洗液压入打印喷头中对打印喷头进行疏通和冲洗。低液位传感器III208用于保证清洗液的最低液量，避免清洗液被压空，高液位传感器III209可避免液量过多而溢出。
进一步的，所述前端盖3上安装有正压接头308，所述正压接头308与所述正压腔18相连通。
进一步的，所述前端盖3的内侧设有分别与所述水腔I15、水腔II16、隔离腔17、正压腔18相匹配的凸台，所述水腔I15、水腔II16、隔离腔17、正压腔18的外围与所述前端盖3之间分别设有密封圈。
进一步的，所述后端盖2的内侧设有分别与所述水腔I15、水腔II16、隔离腔17、正压腔18相匹配的凸台，所述水腔I15、水腔II16、隔离腔17、正压腔18的外围与所述后端盖2之间分别设有密封圈。
凸台和密封圈的设置使得墨盒体1与前端盖3和后端盖2之间的密封效果更好。
实施例8：
在上述任一实施例的基础上，所述墨盒体1的供墨腔11和回流墨腔12的下端分别安装有电磁阀6，所述电磁阀6分别与所述供墨腔11和所述回流墨腔12的通墨孔相连通。
进一步的，所述墨盒体1的下端设有通槽19，通过螺钉和方螺母将所述电磁阀6安装于所述墨盒体1的下端。
本实施例中，通槽19的设置使得电磁阀6的安装位置灵活可调，并且电磁阀6通过螺钉和置于通槽19内的方螺母固定安装于墨盒体1下端，相比电磁阀6直接安装于铝制的墨盒体1上更加牢固。
