本申请涉及打印技术领域，特别是涉及一种墨盒结构、注墨方法及其打印机。
打印机作为常见的办公设备，为现代化办公提供了极大的方便，喷墨打印机是其中重要的分支，以其体积小，色彩丰富，非接触式喷印，机器性价比高等优势，受家庭用户和企业用户的青睐。
墨盒作为喷墨打印机的耗材产品，为了与相应型号的打印机适配，墨盒体积也相应的变小；为了减少用户更换墨盒的频率、提升用户体验，还需要在较小的墨盒内，尽量存储更多的墨水；为了实现高质高效的打印，墨盒一般装在距离喷头最近的字车内，墨盒随字车一起做加速往复运动，运动中的墨盒向喷头连续稳定的供墨。
现有墨盒，随着打印工作的持续，墨盒内不断下降的液面为液面晃动提供了充分条件特别在喷墨打印机执行连续多页高覆盖率打印时，连续的加速的往复运动的字车，使墨盒内液面晃动达到峰值，容易导致供墨腔连通储墨腔的一端暴漏在空气中，致使打印机喷头因吸入空气导致打印断线现象的发生。
发明内容
基于此，有必要针对上述技术问题，提供一种能够避免液面晃动、打印时墨水的供应稳定、连续的墨盒结构及其打印机。
一种墨盒结构，包括墨盒，所述墨盒内具有储墨腔以及供墨腔，所述储墨腔用于存储墨水，所述墨盒的底部开设有与所述供墨腔连通的出墨口；
所述墨盒还具有呈长条状设置的缓存腔，所述缓存腔及所述供墨腔位于所述储墨腔的一侧，且所述缓存腔收容于所述储墨腔内，所述供墨腔位于所述缓存腔底部的下方；所述缓存腔靠近所述供墨腔一端的侧壁上开设有过墨孔，所述缓存腔与所述储墨腔通过所述过墨孔连通，并缓存来至所述储墨腔的墨水；所述储墨腔靠近所述供墨腔一端的底面上开设有贯穿的并与所述供墨腔连通的连通孔，所述连通孔位于所述缓存腔内，所述缓存腔内的墨水通过所述连通孔流入所述供墨腔，并经所述供墨腔输送至所述出墨口,以使打印机能够连续从所述出墨口获取墨水进行打印作业。
在其中一个实施例中，所述缓存腔呈长方形，所述缓存腔的高度至少是所述缓存腔宽度及/或长度的1.5倍。
可以理解的是，由于缓存腔呈长方形，即沿竖直方向，所述缓存腔深度较深，即使剧烈的液面晃动也不会导致供墨腔暴漏在空气中，从而进一步地提高打印时墨水的供应稳定、连续性。
在其中一个实施例中，沿所述缓存腔的高度方向，所述过墨孔的内径范围在1mm-5mm之间。
可以理解的是，将过墨孔的内径范围设置在1mm-5mm之间，即在同一时间内只允许气体或液体之一通过并进/出所述缓存腔，从而在注墨时，墨水依 次经过出墨口、供墨腔缓存腔和过墨孔进入储墨腔，能够优先确保供墨腔和缓存腔处于饱和状态；同时，避免储墨腔内的空气和缓存腔内的墨水之间气液交换，确保供墨腔和缓存腔内的墨水始终处于饱和状态。
在其中一个实施例中，所述墨盒内设有引导单元，所述引导单元用于引导所述过墨孔处的气泡往所述缓存腔远离所述连通孔一端运动。
可以理解的是，引导单元的设置，其能够防止从过墨孔进入缓存腔内的气泡或空气进入供墨腔内，以避免打印机在打印时，其喷头与气泡或空气接触，即能够保证打印机取墨的连续性及稳定性。
在其中一个实施例中，所述引导单元包括引挡板，所述引挡板位于所述缓存腔内且形成于所述储墨腔靠近供墨腔一端的底面，所述引挡板围设在所述连通孔周向，且沿所述连通孔的轴线方向，所述引挡板的高度大于所述过墨孔的内径，以使所述引挡板与所述缓存腔内壁之间形成引导气泡/空气流动通道。
在其中一个实施例中，所述引挡板上设有过滤单元，所述过滤单元用于过滤流从所述缓存腔流入所述供墨腔的墨水。

可以理解的是，在供墨腔内壁靠近连通孔的一端设置斜面，在液体表面张力以及斜面的引导下，气泡沿着供墨腔的腔壁上移至引挡板处，从而使供墨腔内的气泡远离打印机喷头。
在其中一个实施例中，所述连通孔的孔径小于所述供墨腔的内径，以使 所述供墨腔与所述缓存腔在所述连通孔处形成缩口。
可以理解的是，所述供墨腔与所述缓存腔在所述连通孔处形成缩口，从而部分隔离所述缓存腔与所述供墨腔，以进一步减少储墨腔或者缓存腔内部液面晃动对供墨腔的影响，提高打印机作业时取墨的连续性及稳定性。
在其中一个实施例中，所述墨盒内还具有导气腔，所述墨盒开设有所述出墨口的一端还开设有与大气连通的导气孔，所述储墨腔通过所述导气腔与所述导气孔连通。
可以理解的是，通过设置导气孔及导气腔，从而使储墨腔处于与大气相通的状态，以便于在气压差的作用下，在打印过程中，将储墨腔内的墨水持续输送至所述缓存腔及供墨腔内。
在其中一个实施例中，所述导气腔与所述储墨腔连通处安装有止逆件，所述止逆件用于防止储墨腔的墨水经导气腔流出以及所述导气腔的空气直接流入所述储墨腔。
可以理解的是，止逆件的设置，可以避免储墨腔内的墨水经过连通处进入导气腔，最终泄露到墨盒外面；还可以避免导气腔的空气直接进入储墨腔和供墨腔，为储墨腔和供墨腔提供一定的背压，有效地维持了储墨腔内气压的问题，保证了所述墨盒结构供墨时不滴墨、不混色。
在其中一个实施例中，所述导气腔包括连通腔和止逆腔，所述连通腔与所述导气孔连通，所述止逆腔远离所述导气孔的一端与所述连通腔连通，所述储墨腔靠近所述供墨腔的底部侧壁开设有通气孔，所述储墨腔与所述连通腔通过所述通气孔连通，所述止逆件设于所述通气孔处。
在其中一个实施例中，所述墨盒包括主体以及盖板，所述供墨腔开设有于所述主体，所述主体上具有一端敞口设置的第一腔室，所述盖板上设有缓存 部，所述缓存部上具有一端敞口设置的第二腔室，所述盖板密封地盖设于所述主体的敞口处，并使所述缓存部伸入所述第一腔室且密封地抵靠于所述第一腔室的底部，所述盖板与主体之间围成所述储墨腔，所述缓存部与所述第一腔室的底部围成所述缓存腔。
在其中一个实施例中，所述墨盒包括主体以及盖板，所述供墨腔开设有于所述主体，所述主体上具有一端敞口设置的第一腔室，所述第一腔室底部具有向所述敞口处延伸的缓存部，所述缓存部上具有敞口的第二腔室，所述盖板密封地盖设于所述主体的敞口及缓存部的敞口处，并与分别所述主体及所述缓存部之间围成所述储墨腔和缓存腔。

本申请还提供如下技术方案：
一种打印机，包括墨盒结构，所述墨盒结构采用上述所述的墨盒结构。
上述的墨盒结构具有以下优点：
所述墨盒结构通过设置长条状的缓存腔，缓存腔与所述储墨腔之间通过所述过墨孔连通，供墨腔通过连通孔与缓存腔连通，从而储墨腔与所述供墨腔之间通过缓存腔分离，并打印机工作时，在吸力以及墨水重力作用下，所述供墨腔内的墨水取自缓存腔，从而使所述缓存腔、供墨腔内的墨水能够相对保持饱和状态；可以理解的是，相对保持饱和状态下的缓存腔、供墨腔，能够避免 供墨腔受储墨腔内液面晃动的影响，从而确保打印机喷头能够连续、稳定地取墨，避免出现打印断线的现象。

如图1所示，本申请提供一种打印机，打印机(图未示)包括墨盒结构100及墨车，墨盒结构100安装于墨车，并随墨车一起做加速往复运动。墨盒结构100用于存储墨水，并为打印机打印文件时提供连续稳定的墨水。
当然，本申请中的打印机除了上述阐述的墨盒结构100及字车，其还包括打印控制器、废墨回收装置、打印机壳、喷头以及驱动电机等，上述结构共同配合以实现打印机的功能。
如图2所示，墨盒结构100包括墨盒10，墨盒10内具有储墨腔11以及供墨腔12，储墨腔11用于存储墨水，墨盒10的底部开设有与供墨腔12连通的出墨口13；墨盒10还具有呈长条状设置的缓存腔14，缓存腔14及供墨腔12位于储墨腔11的一侧，且缓存腔14收容于储墨腔11内，供墨腔12位于缓存腔14底部的下方；缓存腔14靠近供墨腔12一端的侧壁上开设有过墨孔141，缓存腔14与储墨腔11通过过墨孔141连通，并缓存来至储墨腔11的墨水；储墨腔11靠近供墨腔12一端的底面上开设有贯穿的并与供墨腔12连通的连通孔， 连通孔位于缓存腔14内，缓存腔14内的墨水通过连通孔流入供墨腔12，并经供墨腔12输送至出墨口13,以使打印机能够连续从出墨口13获取墨水进行打印作业。
可以理解的是，墨盒结构100通过设置长条状的缓存腔14，缓存腔14与储墨腔11之间通过过墨孔141连通，供墨腔12通过连通孔111与缓存腔14连通，从而储墨腔11与供墨腔12之间通过缓存腔14分离，并打印机工作时，在吸力以及墨水重力作用下，供墨腔12内的墨水取自缓存腔14，从而使缓存腔14、供墨腔12内的墨水能够相对保持饱和状态；可以理解的是，相对保持饱和状态下的缓存腔14、供墨腔12，能够避免供墨腔12受缓存腔14或者储墨腔11内液面晃动的影响，从而确保打印机喷头能够连续、稳定地从供墨腔12取墨，避免出现打印断线的现象。
换而言之，缓存腔14缓存来至储墨腔11的墨水，当打印作业时，供墨腔12内消耗的墨水，可以即时通过储墨腔11或缓存腔14进行补充，从而使缓存腔14和/或供墨腔12基本处于相对饱和的状态，以避免高速往返运动下的墨盒10的出墨口13处液面的晃动，而使出墨口13暴漏在空气中或混入气泡，即消除了液面晃动对打印的影响，确保了打印机的喷头能够连续、稳定地取墨，避免出现打印断线的现象。
优选地，参阅图1，墨盒10大致呈长方体形。当然，在其他实施例中，墨盒10的形状可以根据实际安装需求而设置。墨盒10可以注塑成型，从而在其内部形成储墨腔11、供墨腔12以及缓存腔14等。
储墨腔11的形状与墨盒10整体的形状相互匹配。在其他结构条件都满足的情况下，储墨腔11体积大致占墨盒10体积的2/3-7/8之间，这样可以保证墨盒10能够在最大程度上储存墨水，以减少用户更换墨盒的频率提升用户体验， 提高打印效率。
进一步地，供墨腔12呈长方形，当然，在其他实施例中，供墨腔12的形状可以根据实际安装需求而设置，例如可以设置成椭圆形、圆柱形等。
供墨腔12的高度至少是其宽度或长度的1.5倍。
进一步地，如图2所示，连通孔111位于缓存腔14内，且连通孔111的孔径小于供墨腔12的内径，即供墨腔12与缓存腔14之间在连通孔111处形成缩口，以使供墨腔12具有连通孔111的一端形成了阻挡台阶。
可以理解的是，缩口具有部分隔离供墨腔12与缓存腔14、储墨腔11的作用，从而能够减少储墨腔11或者缓存腔14内部液面晃动对供墨腔12的影响，有效地确保了打印机作业时取墨的连续性及稳定性。
进一步地，如图2及图3所示，墨盒10内设有引导单元15，引导单元15用于引导过墨孔141处的气泡往缓存腔14远离连通孔一端运动。
可以理解的是，通过引导单元15引导，从而相对于规定了气泡/空气的运动路线(流动方向)，以防止从过墨孔141进入缓存腔14内的气泡或空气进入供墨腔12内，即使气泡或空气远离连通孔111，以避免打印机在打印时，其喷头与气泡或空气接触，进一步地保证打印机取墨的连续性及稳定性。
具体地，引导单元15包括引挡板151，引挡板151位于缓存腔14内且形成于储墨腔11靠近供墨腔12一端的底面，引挡板151围设在连通孔111周向，且沿连通孔111的轴线方向，引挡板151的高度大于过墨孔141的内径，即引挡板151远离储墨腔11底面的一端高于过墨孔141在缓存腔14侧壁的位置，以使引挡板151与缓存腔14内壁之间形成引导气泡/空气流动通道152。
可以理解的是，当气泡或空气从过墨孔141进入缓存腔14内时，气泡或空气会顺着通道152运动；当气泡或空气从通道152流出后，其会自动往远离 连通孔111的一端运动，即运动到缓存腔的顶部。
优选地，引挡板151上设有过滤单元151a，过滤单元151a用于过滤流从缓存腔14流入供墨腔12的墨水。可以理解的是，过滤单元151a的设置，不仅可以过滤墨水中的杂质，还可以阻挡气泡进入供墨腔12或消除气泡，避免气泡进入打印机喷头导致打印断线。
具体地，过滤单元151a可以为滤网或者其他具有过滤功能的部件。
如图2所示，供墨腔12靠近墨盒10与墨盒连接的一端设置，供墨腔12大致呈长方体形，供墨腔12的高度分别大于其宽度及长度，以使供墨腔12沿高度(竖直)方向呈长条状的长方体形。可以理解的是，将供墨腔12设置成长条状，即使供墨腔12内的液面晃动，也能尽量避免其对出墨口13的影响。
优选地，供墨腔12的高度是其宽度及长度的1.5以上。
进一步地，供墨腔12内壁靠近连通孔111的一端设有用于引导气泡流动的斜面121，即阻挡台阶的台阶面为斜面，斜面121从出墨口13至连通孔111方向倾斜，且斜面的高位靠近连通孔111设置，斜面的低位靠近出墨口13设置。
需要解释的，斜面的高位和斜面的低位是相对的，其是以出墨口13作为参照比对，沿连通的轴线方向，距离出墨口13最远的高位，反之为低位。
可以理解的是，在供墨腔12内壁靠近连通孔111的一端设置斜面121，在液体表面张力以及斜面121的引导下，供墨腔12内的气泡沿着腔壁上移至连通孔111处或通过连通孔111进入缓存腔14或储墨腔11，从而使供墨腔12内的气泡远离打印机喷头，避免供墨腔12内的气泡积压，喷头在取墨时与气泡接触。
请继续参阅图2，缓存腔14长条形。优选地，在本实施例中，缓存腔14为长方体。当然，在其他实施例中，缓存腔14的形状可以根据实际安装需求而 设置。缓存腔14高度至少是缓存腔14宽度或长度的1.5倍，以使缓存腔14沿竖直(自身的高度)方向呈长条形设置。
可以理解的是，缓存腔14呈长条形设置，即沿竖直方向，缓存腔14深度较深，即使剧烈的液面晃动也不会导致供墨腔12暴漏在空气中，从而进一步地提高打印时墨水的供应稳定以及连续性。
优选地，沿竖直(高度)方向，过墨孔141的内径范围在1mm-5mm之间，并同一时间只允许气体或者液体之一进/出缓存腔14。可以理解的是，墨盒注墨(灌装)时，墨水在正负压力和自身重力的作用下，依次经过出墨口13、供墨腔12、连通孔111、缓存腔14和过墨孔141，最后进入储墨腔11，墨水流经顺序确保了供墨腔12和缓存腔14优先处于饱和状态，较细的过墨孔避免了储墨腔11的空气和缓存腔14墨水间的气液交换，确保了供墨腔12和缓存腔14的墨水始终处于饱和状态，避免晃动条件的成立。
需要解释是，将过墨孔141的内径范围设置在1mm-5mm，首先能够保证打印时，过墨孔141的供墨量能够正常匹配打印时墨水的消耗，避免供墨腔12出现墨水供应不及时的情况；其次，在储墨腔11内的压力为大气压或者处于一定压力的情况下，能够避免缓存腔14内的墨水导流至储墨腔，即确保缓存腔14内的墨水能够处于饱和状态。
当然，在其他实施例中，过墨孔141处还可以设置阀门，在该实施例中过墨孔141的尺寸可以不做要求；因此，此时阀门的功能及作用替代或者就相当于过墨孔141的内径范围设置在1mm-5mm的功能及作用。
如图2所示，墨盒10内还具有导气腔16，墨盒10开设有出墨口13的一端还开设有与大气连通的导气孔17，储墨腔11通过导气腔16与导气孔17连通，从而使使储墨腔11与大气连通。
可以理解的是，通过设置导气孔17及导气腔16，从而使储墨腔11处于与大气相通的状态，以便于在气压差以及打印吸力的作用下，打印过程中，将储墨腔11内的墨水持续输送至缓存腔14及供墨腔12内。
如图2所示，优选地，导气腔16与储墨腔11之间可以通过管路连通或者直接通过在导气腔16的侧壁开设通气孔161(即储墨腔11的侧壁)，并通过通气孔161将导气腔16与储墨腔11之间连通。
进一步地，导气腔16与储墨腔11的连通处，即通气孔161处安装有止逆件171，止逆件171用于防止储墨腔11的墨水经导气腔16流出以及导气腔16的空气直接流入储墨腔11。换而言之，止逆件171用于正向防止导气腔16内的气体通过连通处(通气孔161)直接进入储墨腔11，反向防止储墨腔11的墨水通过连通处进入导气腔16，从而，为储墨腔11和供墨腔12提供一定的背压，有效地维持了储墨腔11内气压的问题，保证了墨盒结构100供墨时不滴墨、不混色。
优选地，止逆件171可以为单向阀、海绵或者其他具有上述功能的功能件。
优选地，在本实施例中，止逆件171为海绵。
进一步地，如图4所示，导气腔16包括连通腔162和止逆腔163，连通腔162与导气孔17连通，止逆腔163远离导气孔17的一端与连通腔162连通，从而实现连通腔162与大气的相通。通气孔161开设于储墨腔11靠近供墨腔的底部侧壁，并止逆腔163连通，止逆件171设置在通气孔161处。
可以理解的是，在运输过程中，储墨腔11内的一小部分墨水通过通气孔161流出至止逆腔163，但会被海绵吸收。而浸湿的海绵会将通气孔161封堵，以使储墨腔11内的墨水无法流出；同时，连通腔162和止逆腔163分隔，从而 也能够避免墨水流入连通腔162。在打印过程中，打印时的吸力会使大气经过海绵在进入到储墨腔11内。
优选地，导气腔16内设置有隔板164，隔板164将导气腔16分隔成连通腔162和止逆腔163。隔板164远离导气孔17的一端开设有通孔164a,连通腔162和止逆腔163通过该通孔164a连通。
实施例1
如图4及图5所示，墨盒10包括主体18以及盖板19，供墨腔12开设有于主体18，主体18上具有一端敞口设置的第一腔室181，盖板19上设有缓存部191，缓存部191上具有一端敞口设置的第二腔室191a，盖板19密封地盖设于主体18的敞口处，并使缓存部191伸入第一腔室181且密封地抵靠于第一腔室181的底部，盖板19与主体18之间围成储墨腔11，缓存部191与第一腔室181的底部围成缓存腔14。
优选地，第一腔室181内壁上设有筋条181a，盖板19的一侧设有卡接部192，在盖板19密封地盖设于主体18上时，卡接部192卡于筋条181a上，以进一步地提高盖板19与主体18之间连接的可靠性。
进一步地，主体18的一侧还设有操作部182，操作部182用供操作握持，以拆/装墨盒10。
优选地，操作部182可以是把手等。
进一步地，主体18上还设有芯片183等部件，芯片183用于记录墨盒10的相关信息。需要解释的，相关信息可以是墨水消耗量、墨水余量、墨盒型号等信号。可以理解的是，通过芯片183来记录墨盒10的内墨水的剩余量，以便于用于及时获知墨水使用情况，并及时对墨盒10进行补充墨水，提高打印效率。
如图6所示，墨盒结构100还包括密封膜20以及密封塞30，密封塞30 密封地安装于供墨腔12内，出墨口13开设于密封塞30上，密封膜20连接于墨盒10上并能够将供墨腔12密封。从而避免运输过程中，墨盒10内部的墨水从供墨腔12跑出。
进一步地，密封膜30能够同时密封供墨腔12以及导气孔17，密封膜20能够被喷头210刺破，并使所述导气孔17连通外界空气；密封膜20与密封塞30之间的距离大于或等于喷头210的半径。
即，在这里，使用一片密封膜20同时密封导气孔17和供墨腔12，户在使用时仅需将墨盒10装入车库，再由喷头刺破密封膜20即可使用，使得供墨腔12和导气孔17在一个安装动作下同时开放，省去了撕开导气孔上的密封膜20这一步骤，减少了更换墨盒10时的操作步骤，降低出现意外的风险，用户的使用体验更佳；此外，密封膜20与密封塞30之间的距离大于或等于所述喷头的半径，避免了卷曲的密封膜20夹在喷头和密封塞30内，同时避免了卷曲的密封膜20过长，堵塞供墨腔12和导气孔17之间的连通。
实施例2
在实施例2中，墨盒10的结构和实施例1中墨盒10结构基本是一致的，其不同之处在于，缓存部191集成在主体18的第一腔室181内；此时，第一腔室181的开口与第二腔室191a的开口朝向相同，盖板19密封地盖设于主体18的敞口及缓存部191的敞口处，并与分别主体18及缓存部191之间围成储墨腔11和缓存腔14。
本申请还提供一种墨盒结构的注墨方法，该注墨方法用于对本申请上述公开的墨盒结构100进行注墨，注墨方法包括至少以下步骤：
S1往出墨口13注充墨水，墨水依次经供墨腔12、连通孔111、缓存腔及过墨孔141进入储墨腔11；及
S2待供墨腔12充满墨水后，停止注墨并封闭出墨口13。
可以理解的是，上述在对墨盒结构100注墨时，由于墨水是依次经过出墨口13、供墨腔12、连通孔111、缓存腔14和过墨孔141，最后进入储墨腔11；从而，可以确保供墨腔12和缓存腔14优先处于饱和状态，以下注墨阶段就避免晃动条件的成立，为后续打印时，连续、稳定的墨水供应提供良好的基础。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
