技术领域
本申请涉及打印设备技术领域，特别是涉及一种阀组件以及具有其的墨盒。
背景技术
随着技术的发展，打印机成为企业办公的必要设备，进而带动打印耗材的蓬勃发展，打印耗材多种多样，例如墨盒、硒鼓等。墨盒在装入打印机进入打印状态后，伴随墨水的消耗会在储墨腔中形成负压，墨盒内外压力需要保持平衡才能保证打印不会中断，此外，墨盒内外压力不平衡将会出现供墨系统异常，在打印过程中压力过大会导致缺色，打印静置时压力泄露会导致出现混色，从而使得打印性能不稳定、不可靠，打印质量较差。
为了消除墨水外溢以及墨水未尽但打印中断的不良现象，需要改善墨盒的气压平衡性能以及密封性能，现有的墨盒设有与充气口连接的可变形腔以及伴随可变形腔膨胀或收缩时关闭或打开的单向阀，可变形腔与单向阀单独设置，这样使得墨盒结构复杂，且可变形腔和单向阀占用了较多的储墨腔内空间，另外，可变形腔不利于高强度打印，导致墨盒使用寿命较短。

除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请。本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的和所有的组合。
如图1和图2所示，本申请提供一种墨盒200，该墨盒200包括壳体210以及阀组件100，至少部分的阀组件100设置于壳体100内，并用以对墨盒200内的气压进行调节。
具体地，壳体210内形成有用于容纳并储存墨水的储墨腔211，且壳体210的侧壁上开设有充气孔212及出墨孔213，阀组件100能控制所述充气孔212与出墨孔213之间的连 通或断开。
在墨盒200安装至打印机时，加压过程中，充气孔212与充气泵(图未示)连接，充气泵向墨盒200内充入加压空气，迫使储墨腔211中的墨水从出墨孔213流出，实现通墨，流出的墨水被输送至打印喷头。
打印过程中，墨盒200供墨，此时充气泵撤离，充气孔212与大气相连通，储墨腔211内部的墨水不断被消耗，储墨腔211内会产生负压。如果储墨腔211内部负压过大将会导致缺色，墨盒200内墨水无法稳定流出；如果储墨腔211内部负压过小将会导致打印静置状态下墨盒200内墨水泄露，并出现混色，从而使得打印性能不稳定、不可靠，打印质量较差。因此，需要调节储墨腔211内外的压力平衡。
因此，本优选实施例中，通过阀组件100对储墨腔211内的气压进行调节，一方面用以保证墨盒200在安装至打印机时能稳定地加压出墨，另一方面在进入打印状态时使得供应至打印机的墨水流量稳定且可控，从而保证打印效果。本申请提供的阀组件100以及墨盒200均具有较佳的气压平衡性能以及密封性能。
进一步地，如图1所示，壳体210大致呈盒状。当然，在其他实施例中，壳体210的形状可以根据不同的装配、应用需求设置成规则或不规则的形状，其具体形状本申请中不作限制。
如图2及图3所示，壳体210包括底座210a以及盖板210b，底座210a以及盖板210b互相扣合。可以理解的是，底座210a和盖板210b之间可以分体设置，并可通过螺接、焊接、铆接或卡接等方式进行固定，也可以一体成型设置。
充气孔212以及出墨孔213开设于底座210a的侧壁上。优选地，出墨孔213和充气孔212位于底座210a上的同一侧壁上，以便于安装和实际使用；通过将出墨孔213与充气孔212相对靠近设置，可以缩短充气孔212与出墨孔213之间的气路传输路径，从而使得该壳体210的结构更加紧凑，进而使得墨盒200的结构更加紧凑和简单。
可以理解的是，出墨孔213和充气孔212也可以位于底座210a上相邻的侧壁或者相对的侧壁上，其设置位置可以根据使用需求进行调整。
如图2所示，壳体210内设有隔板214，隔板214将储墨腔211分隔成第一储墨腔211a和第二储墨腔211b，第一储墨腔211a和第二储墨腔211b均用于储存墨水。其中，第一储墨腔211a与出墨孔213相连通，隔板214上开设有用以连通第一储墨腔211a与第二储墨腔211b的连通孔214a，第二储墨腔211b作为备用的储墨腔，待第一储墨腔211a内的墨水消耗后，第二储墨腔211b内的墨水会通过连通孔214a流至第一储墨腔211a。
作为优选，连通孔214a的数量设为间隔分布的两个。可以理解的是，该储墨腔211 还可以被分隔成超过两个的腔室。
在本实施例中，至少部分阀组件100收容于第二储墨腔211b内，且阀组件100用于调节第一储墨腔211a中压力平衡。
如图3和图5所示，阀组件100包括阀体单元100a以及密封单元130，阀体单元100a内部具有阀腔101，密封单元130密封且活动地设置于阀腔101内，并将阀腔101分隔为第一腔101a以及第二腔101b，且第一腔101a与第二腔101b相互独立。
阀腔101的内侧壁上开设有传输通道102，密封单元130能够沿阀腔101的内侧壁运动，以使传输通道102可选择地连通第一腔101a和/或第二腔101b。
可以理解的是，在图6中，传输通道102可选择地连通第一腔101a和/或第二腔101b指代的是，在密封单元130沿着阀腔101的内侧壁运动的过程中，当密封件131的上侧部位于上止点S1上方时，传输通道102连通第二腔101b；当密封件131位于上止点S1和下止点S2之间时，传输通道102连通第一腔101a和第二腔101b；当密封件131的下侧部位于下止点S2下方时，传输通道102连通第一腔101a。
可以理解的是，在图8中，传输通道102可选择地连通第一腔101a和/或第二腔101b指代的是，在密封单元130沿着阀腔101的内侧壁运动的过程中，当密封凸条131c位于上止点S1上方时，传输通道102连通第二腔101b；当密封凸条131c位于上止点S1和下止点S2之间时，传输通道102连通第一腔101a和第二腔101b；当密封凸条位于下止点S2下方时，传输通道102连通第一腔101a。
作为优选地，密封单元130运动的驱动方式，可以由直接的驱动部件驱动，也可以是由阀腔101内部的压差进行驱动。具体地，在本实施例中，密封单元130运动是由阀腔101内部的压差进行驱动。
具体地，打印过程中，随着第一储墨腔211a中墨水的不断消耗，由于第一储墨腔211a与第二腔101b通过通孔121连通，第二腔101b中负压逐渐增大，由于第一腔101a连通大气，进而第一腔101a与第二腔101b之间的负压差逐渐增大，密封单元130响应第一腔101a与第二腔101b之间的负压差，并在该负压差的作用下沿阀腔101的内侧壁运动，以使传输通道102连通第一腔101a及第二腔101b，或断开第一腔101a与第二腔101b之间的连通。
阀体单元100a包括阀盖110和阀座120，阀座120收容于第二储墨腔211b内，阀盖110盖设于阀座120上并与阀座120围设形成阀腔101。
本优选实施中，第一腔101a相对靠近阀盖110，第二腔101b相对靠近阀座120。加压过程中，第一腔101a通过充气孔212连通打印机的充气泵，第二腔101b连通出墨孔213；打印过程中，第一腔101a连通大气，第二腔101b连通出墨孔213。
进一步地，本优选实施例中的阀盖110与盖板210b一体成型设置，阀座120与底座210a也为一体成型设置。
在本实施例中，阀座120靠近充气孔212设置。优选地，充气孔212自底座210a内侧壁沿自身轴线延伸至阀座120的侧壁。第一腔101a与充气孔212之间设置有充气通道111，并通过该充气通道111连通彼此。在墨盒200安装至打印机时，充气泵通过充气孔212、充气通道111实现对第一腔101a进行充气加压。
在一实施例中，如图5和图6所示，传输通道102的数量为两条，两条传输通道102沿着阀腔101的内侧壁周向间隔设置。当然，传输通道102的数量还是为其他，例如一条或三条不等，其具体的数量可以根据实际的需求设定，在此就不在限定。
作为优选地，在本实施例中，两条传输通道102以阀腔101的轴线对称地设置在阀腔101的内侧壁。
在另一实施例中，如图4所示，所述传输通道102呈环状，且沿阀腔101内侧壁周向设置，即在阀腔101内侧壁周向的一圈连续的传输通道102。
如图5和图6所示，传输通道102沿密封单元130运动方向(即所述阀腔101轴线方向)的延伸长度为L1，L1小于密封单元130沿阀腔101的内侧壁运动的距离。密封单元130在移动时，即密封单元130的位置发生变化，进而使得第一腔101a与第二腔101b之间的气体通道(图9中箭头方向)通过传输通道102连通或断开。
可以理解的是，通过限制传输通道102的长度，可以控制第一腔101a与第二腔101b在预定压力作用下进行连通。
如图5以及图6所示，密封单元130包括密封件131以及弹性件132，密封件131活动且密封地设置于阀腔101内，弹性件132收容于第二腔101b内，且弹性件132的一端与第二腔101b的底部抵接，另一端与密封件131抵接。在充气泵对第一腔101a加压过程中，气压作用于密封件131靠近第一腔101a外表面上。
如图7所示，当充气泵所充的气压作用力小于弹性件132的作用力加上密封件131与阀腔101的内侧壁之间的摩擦力时，第一腔101a与第二腔101b之间的压力处于相对平衡，因此，密封件131不会沿阀腔101的内侧壁移动，此状态称为第一状态，在该状态下，传输通道102与第一腔101a断开，传输通道102与第二腔101b连通，第一腔101a与第二腔101b断开。
如图9所示，充气泵不断向第一腔101a充气，当充气泵所充的气压作用力大于弹性件132的作用力及密封件131与阀腔101的内侧壁之间的摩擦力时，密封件131能够在压力差作用力下，沿阀腔101的内侧壁移动，由于第二腔101b与第一储墨腔211a通过通孔121 连通，故密封件131沿阀腔101的内侧壁向下运动时，其压迫第一储墨腔211a内的墨水从出墨孔213流向打印机喷头；同时，在此状态下，第一腔101a与第二腔10之间通过传输通道102连通，此状态称为第二状态。
如图10所示，充气泵持续向第一腔101a充气，当充气泵所充的气压作用力远远大于弹性件132的作用力及密封件131与阀腔101的内侧壁之间的摩擦力时，密封件131继续朝向第二腔101b向下移动，当密封件131的密封凸条131c移动至传输通道102下止点S2的下方时，第一腔101a与第二腔101b之间气体通路断开，此时称为第三状态。
可以理解的是，第一腔101a与充气孔212连通，在对墨盒200进行加压出墨的过程中，只要充气孔212处进入的气压值足够大，此时密封件131能够在短时间内从第一状态移动至第三状态，加压气体几乎不会通过传输通道102进入第二腔101b，以避免传输通道102长时间连通第一腔101a与第二腔101b，加压气体冲击第一储墨腔211a中的墨水，导致出墨孔213处的墨水飞溅；同时，伴随着密封件131的移动使得第二腔101b的体积变小，从而迫使第一储墨腔211a内的气体能够自出墨口212排出，从而完成加压出墨。
加压结束后，充气泵与充气孔212分离，此时充气孔212与大气相通。由于第一腔101a内的气压值相对减小，密封件131在弹性件132的作用下将从第三状态依次移动至第二状态和第一状态。
如图9所示，密封件131在移动至第二状态的过程中，第一腔101a与第二腔101b之间通过传输通道102连通，可使密封件131上下所受的气压值平衡。密封件131在移动至第一状态时，密封件131与阀腔101的内侧壁抵接并形成密封，大气不会再进入第二腔101b内，可使储墨腔211内的压力恢复至一定的负压值。该充气结束的过程中，不仅能有效保证墨水流出的流畅性，而且可使打印机喷头内的气泡被抽回至储墨腔内。
打印机开始打印的过程中，打印喷头从墨盒200的出墨孔213抽取墨水，第二腔101b中的墨水不断被消耗，此时第二腔101b中的负压会进一步增大，当第二腔101b与第一腔101a之间的负压差值大于弹性件132的弹性力加密封件131与阀腔101内侧壁之间的摩擦力之和时，密封件131将在负压差作用下由第一状态移动至第二状态。
在密封件131移动至第二状态时，空气能够自充气孔212依次进入第一腔101a和第二腔101b，降低第二腔101b中的负压值，此时第二腔101b中的气压值逐渐增大，当第二腔101b的压力与第一腔101a之间的压力差值小于弹性件131回复力时，密封件131将在弹性件132的作用力下复位至第一状态，如此循环往复，可使第二腔101b中的负压值始终控制在稳定范围内。
如图11和图12所示，密封件131的形状与阀腔101的形状相互匹配。在本实施例中， 密封件131呈圆形，其包括密封主体131a以及密封圈131b，密封圈131b围设于密封主体131a的外周侧，用以密封阀腔101的内侧壁。
密封主体131a呈圆形。密封主体131a可以由PP或ABS等塑胶材料制成。优选地，密封圈131b可以与密封主体131a设置一体式或者分体式。密封圈131b可以为橡胶圈、硅胶圈或者其他具有密封性能的部件。在本实施例中，密封圈131b为橡胶圈，且密封圈131b与密封主体131a之间为分体式。
如图11所示，密封圈131b沿密封单元130运动方向(所述阀腔101轴向方向)的厚度为L2，L1与L2的关系为，L1大于L2，即，密封圈131b沿密封单元130运动方向的厚度小于传输通道102沿密封单元130运动方向的长度，从而，在密封圈131b运动至传输通道102的位置时，使第一腔101a与第二腔101b之间能够通过传输通道102连通。
传输通道102沿密封单元130运动方向的延伸长度小于密封圈131b沿阀腔101的内侧壁运动的距离。密封圈131b在移动时，即密封圈131b的位置发生变化，进而使得第一腔101a与第二腔101b之间的气体通道(图5中箭头方向)通过传输通道102控制连通或断开。
如图12和图13所示，密封主体131a的周侧外壁上具有向外凸出的安装部1311，密封圈131b密封地套设于安装部1311上。
优选地，密封主体131a朝向第一腔101a的表面与密封圈131b靠近所述第一腔101a的表面齐平设置，以使密封主体131a整体的受力均匀。
进一步地，如图6及图11或12所示，密封主体131a朝向第一腔101a的一侧表面上设有凹部1312，阀体单元100a的内表面上具有定位柱112，定位柱112能够与凹部1312配合，以限位密封件131沿阀腔101的内壁运动的运动范围。
具体地，定位柱112设于阀盖110的内表面上，定位柱112能够与凹部1312配合，以限位密封件131沿阀腔101的内侧壁朝向阀盖110运动的运动范围。
当密封主体131a向第一腔101a方向运动至定位柱112与所述凹部1312配合时，此时定位柱112顶住密封主体131a，从而限制密封主体131a过渡地靠近所述阀盖110运动。
优选地，凹部1312可以为凹槽或者孔，定位柱112伸入凹部1312内，以与密封主体131a抵靠，从而限制密封主体131a的运动。
当然，在其他实施例中，凹部1312所在的位置与定位柱112所在的位置也可以进行互换，其同样能够实现密封主体131a的限位；同时，凹部1312也可以替换成其他能够与定位柱112配合的结构，在此就不再赘述。
进一步地，如图6所示，密封主体131a朝向第二腔101b的表面凸设有第一定位部1313，第二腔101b的底部凸设有第二定位部122，弹性件132的一端套设于第一定位部1313， 另一端套设于第二定位部122，从而实现弹性件132的安装。
优选地，第二定位部122是设于阀座120上并与阀座120设置为一体式。
第一定位部1313与凹部1312相对应设置。密封主体131a朝向第一腔101a的表面上设有向第二腔101b的方向凹陷并形成有凹部1312，同时在密封主体131a的另一表面凸出形成该第一定位部1313，凹部1312的部分延伸至第一定位部1313。
优选地，第二定位部122可以与阀座120设置为一体式结构。
如图6所示，可选地，第二定位部122的外侧壁上设有限位凸起122a，限位凸起122a与弹性件132限位配合，以防止弹性件132脱离第二定位部122。
具体地，限位凸起122a为设置在第二定位部122外侧壁上的倒钩结构，当弹性件132套设于第二定位部122时，该倒钩结构将弹性件132勾住，实现弹性件132的限位。
进一步地，如图12和图13所示，密封圈131b还包括密封凸条131c，密封凸条131c凸设于密封圈131b外周侧，并与阀腔101的内侧壁密封接触。可以理解的是，在这里，是依靠密封凸条131c与阀腔101的内侧壁之间作用，以实现密封件131与阀腔101内侧壁的密封接触。当然，在其他实施例中，密封凸条131c也可以省略，也可以直接通过密封圈131b与阀腔101的内侧壁密封接触。
密封凸条131c的数量大于或等于一条。具体地，在本实施例中，密封凸条131c的数量为两条，两条密封凸条131c间隔地分布于密封圈131b的上下两侧，从而在密封的过程中形成双重密封的效果，以提高其密封性。当然，在其他实施例中，密封凸条131c的数量还可以设置为1条、3条等，其具体的数量可以根据实际的密封需求而设置。
作为优选地，如图13所示，两个所述密封凸条131c之间的距离为L3，L1大于L3，即传输通道102沿密封单元130运动方向的延伸长度大于两个密封凸条131c之间的距离，从而避免在密封件131运动至预定位置时，无法通过传输通道102连通第一腔101a与第二腔101b。
可选地，密封凸条131c可以与密封圈131b设置为一体式或分体式。在本实施例中，密封凸条131c与密封圈131b设置为一体式，即密封圈131b的周侧向外凸出形成有密封凸起。
本申请提供的阀组件100以及墨盒200，通过设置密封单元以及传输通道，密封单元沿阀腔的内侧壁运动，从而选择性地使传输通道连通第一腔和第二腔，以使第二腔在打印过程中保持一定的负压，进而保证稳定出墨，这种调节气压平衡的方式能够较好的实现墨水稳定流出，打印效果较好，使得墨盒具有良好的气压平衡性能和密封性能。此外，本申请提供的墨盒结构紧凑，受用寿命较长，墨盒中阀组件所占体积较小，因而墨盒具有较大的储墨体积，且墨盒具有良好的气压平衡性能以及密封性能。
此外，需要说明的是，使用“第一”、“第二”等词语来限定零部件，仅仅是为了便于对相应零部件进行区别，如没有另行声明，上述词语并没有特殊含义，因此不能理解为对本申请保护范围的限制。
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本申请专利保护范围的限制。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。
