在使用墨盒前,把封闭板542的舌形片545脱出,以便使舌形片545的颈部543处断开,与主要部分544分离。 Before using the ink cartridge, the closing plate 542 coming out of the tongue 545, neck portion 543 so that the tongue 545 is turned off, separated from the main portion 544. 因此,装墨孔514,514′和514″经槽540,540′和540″与放气口541,541′和541″流体连通。同样,泡沫材料室经槽540,540′和540″与放气口541,541′和541″从而与大气流体连通。因此,在防止油墨蒸发的同时,使墨盒得到排气。 Accordingly, the ink charging hole 514,514 'and 514 "by the slots 540, 540' and 540" and the discharge port 541, 541 'and 541' in fluid communication. Also, the foam chamber through the slots 540, 540 'and 540 "of the discharge port 541, 541 'and 541 "so that fluid communication with the atmosphere. Thus, while preventing evaporation of the ink, the ink container to obtain the exhaust gas.

现在参见图7(a)和(b),其中墨盒的供墨口513的位置要与记录头供墨针状体550对中。 Referring now to FIG. 7 (a) and (b), wherein the position of the ink supply port 513 of the ink cartridge to the recording head and the ink supply needle 550 pairs in. 此后,在插入墨盒时将它推向记录头。 Thereafter, when it is inserted into the recording head cartridge. 供墨针状体550的圆锥部分551穿过薄膜密封件546与图7(a)所示的密封件530的孔配合。 The conical portion 551 of the ink supply needle 550 through the film 546 and the seal member of FIG. 7 (a) hole-sealing member 530 shown in FIG fit. 由一密封件530的开口向上,所以在供墨针状体550的圆锥形部分551使密封件530弹性变形时,供墨针状体550便穿过密封件530。 A sealing member upwardly from the opening 530, so that the conical portion 551 of the ink supply needle 550 when the seal 530 is elastically deformed, then the ink supply needle 550 through the seal 530.

使用墨盒时,供墨针状体550穿过密封件530。 When using the cartridge, the ink supply needle 550 through the seal 530. 密封件530的连接部分534的弹性促使圆锥部分532与供墨针状体550配合。 An elastic seal connecting portions 534 and 532 causes the conical portion 550 with the ink supply needle 530. 即使记录头的供墨针状体550与密封件530的中心稍有轴线不重合,供墨针状体550的供墨口513也能实现气体密封。 Even if the center of the recording head, the ink supply needle 550 and the sealing member 530 slightly axes are not coincident, the ink supply needle 513 of the ink supply port 550 of the gas seal can also be achieved.

安装墨盒后,为了将油墨引入记录头或利用油墨的喷射性能,给记录头和贯穿的供墨针状体550施加负压,以使盒中的油墨穿过供墨针状体550流入记录头。 After installing the ink cartridge, to be introduced into the recording head or the ink ejecting property of the ink using the negative pressure is applied to the recording head and the ink supply needle 550 therethrough, so that the ink cartridge through the ink supply needle 550 flows into the recording head . 由于压差的存在,施加给墨盒的这个高负压使气密地把墨盒与大气相密封和相隔绝的密封件530的圆锥部分532如图7(a)所示上升朝向墨盒的内部。 Due to differential pressure applied to the ink container hermetically high negative pressure (a), rising towards the interior of the ink cartridge 7 and the cartridge sealed from the atmosphere isolated from the sealing member 530 of the conical portion 532 of FIG. 因此,这个压差有助于使密封件530的圆锥部分532弹性地压向供墨针地压向供墨针状体550,从而有助于气密地密封墨盒。 Thus, the pressure differential helps the sealing member 532 of the conical portion 530 is elastically pressed toward the ink supply needle pressed toward the ink supply needle 550, to facilitate the ink container hermetically sealed.

即使供墨针状体550没有完全插入密封件530,只要供墨针状体550的圆锥形部分551与图7(b)所示的圆锥部分532保持接触,密封件530的圆锥部分532内的弹性力使圆锥部分532与供墨针状体550保持接触。 Even if ink supply needle 550 is not fully inserted into the sealing member 530, as long as the ink supply needle 550 of the conical portion 551 as shown in (b) of FIG. 7 and held in contact with the conical portion 532, 532 seal the inner cone portion 530 the elastic force of the tapered portion 532 and the ink supply needle 550 is held in contact. 因此,即使没有将针状体完全插入,也能确保密封件530和供墨针状体550的气密性。 Thus, even without the needle is fully inserted, the seal member 530 can be ensured and the airtightness of the ink supply needle 550.

由于在与密封件530接触时供墨针状体550的顶部被密封,所示可使墨盒内的无用空间很小,可防止由将墨盒插入记录头时的活塞效应产生的空气泡进入墨盒。 Since the top of the ink supply needle 550 is in contact with the seal member 530 is sealed, can dead space within the ink cartridge shown in small, the air can be prevented by the piston effect generated when the bubbles enter the recording head cartridge into the ink cartridge.

当通过记录头的喷嘴开口施加负压时,多孔件520所吸收的油墨经通孔524和供墨针状体550的通孔552流入记录头。 When negative pressure is applied through the nozzle opening of the recording head, the ink of the porous member 524 through the through hole 520 and absorbed by the through hole 550 of the ink supply needle 552 flows into the recording head. 当预定量的油墨离开多孔件520被消耗,多孔件520的中的油墨量减少时,油墨室512内的压力超过连通孔519附近的多孔件520的吸持力,因此,空气泡在连通孔519进入油墨室512。 When a predetermined amount of ink leaving the porous member 520 is consumed, reducing the amount of ink in the porous member 520, the pressure in the ink chamber 512 over communication confining force of the porous member near the hole 519,520 is, therefore, the air bubbles in the communication hole 519 into the ink chamber 512. 因此,油墨室512内的压力增加,因而油墨流入泡沫材料室511。 Thus, the pressure in the ink chamber 512 increases, and the ink chamber 511 flows into the foam material.

流入泡沫材料室511的油墨被多孔件520吸收,并使泡沫材料室511的油墨量增加。 The ink chamber 511 flows into the foam material 520 is a porous absorbent member, and increasing the amount of the ink chamber 511 of the foam. 在连通孔519附近的多孔件520的油墨吸持力与油墨室512内的压力平衡的时刻,油墨从油墨室512向泡沫材料室511的流动停止。 In the porous member near the ink communication holes 519,520 holding force and pressure in the ink chamber 512 of a time balance, the ink from the ink chamber 512 to stop the flow of foam chamber 511.

图8所示的曲线表示这个过程。 Curves shown in FIG. 8 represents this process. 在该图中,字母F表示泡沫材料室511的多孔件520中的压力值,它母G表示油墨室512内的油墨量。 In the figure, letter F indicates the pressure value of the porous foam member 520 in the chamber 511, which parent G represents the amount of ink in the ink chamber 512. 当多孔件520中最初所含有的预定量的油墨W1被消耗,从而多孔件520中的油墨量减少到预定值时,由于在此预定值下,油墨室512内的压力超过连通孔519附近的多孔件520的油墨吸持力,所以油墨便逐渐地从油墨室512流入泡沫材料室511。 When a predetermined amount of ink porous member 520 initially contained W1 is consumed, thereby reducing the amount of ink porous member 520 to a predetermined value, since this predetermined value, the pressure in the ink chamber 512 over the communication vicinity of the hole 519 a porous ink holding force member 520, so that the ink 512 will be gradually flows into the foam chamber 511 from the ink chamber. 这个过程进行到油墨室512内的压力与连通孔519附近的多孔件520的油墨吸持力重新恢复平衡为止。 The process proceeds to the porous member near the ink pressure in the ink chamber communicating holes 512,519,520 holding force rebalance far. 结果,尽管油墨室512内的油墨量在逐渐减少,但多孔件520中的油墨量基本上保持不变,从而按不变的压差以不变的速率供给记录头油墨。 As a result, although the amount of ink in the ink chamber 512 is gradually reduced, but the amount of ink in the porous member 520 remains substantially constant, so that the constant pressure difference at a constant rate of ink supplied to the recording head.

在记录头消耗预定量的油墨W2后,在油墨室512内不会留有油墨,但多孔件520内所含有的油墨量会等于从油墨室间断地供给泡沫材料室511的油墨量。 After the consumption of the recording head W2 of a predetermined amount of ink, the ink in the ink chamber 512 is not left, but the amount of ink in the porous member 520 will equal the amount of ink contained in the foam chamber 511 is supplied intermittently from the ink chamber. 因而,尽管油墨室512中没有用来向多孔件520作补充的油墨,但利用多孔件520内所吸收的油墨量能继续进行打印。 Accordingly, although the ink chamber 512 is not used to supplement the porous member 520 of the ink, but the use amount of the ink absorbed by the porous member 520 can continue printing. 在打印过程中消耗预定量的油墨W3后,多孔件520内的油墨将被用尽,该墨盒将不再维持打印。 After a predetermined amount of ink consumed in the printing process W3, the ink in the porous member 520 is depleted, the print cartridge will not be maintained.

在从油墨室512中所装的全部油墨已被多孔件520吸收到油墨用尽的整个打印过程中,供给打印头的油墨量是不变的。 Entire printing process has been absorbed into porous member 520 in all of the ink from the ink chamber 512 is loaded in the ink out of the ink supply amount of the printhead is constant. 用尽油墨室512内的油墨表明油墨盒中的油墨即将被用尽。 Exhaustion of ink in the ink chamber of the ink cartridge 512 indicate the ink is about to be exhausted. 如果在这种程度下插入一个新墨盒,就可确保供给记录头的油墨不被中断。 If a new cartridge is inserted in such a degree that can ensure that the ink supplied to the recording head is not interrupted.

如上所述,在打印过程中,必须使本发明的墨盒的内部空间保持在负压状态下。 As described above, in the printing process, the interior space of the ink must be maintained in the present invention, the negative pressure state. 除了在供墨口和供墨针状体之间实现上述的气体密封外,从油墨室512向泡沫材料室511输送油墨必须正常地进行,以确保供给记录头的油墨的流量不变。 In addition to the ink supply port and said gas supply to achieve a seal between the ink supply needle, the ink is delivered from chamber 512 to chamber 511 of the ink foam material normally must be to ensure that the flow rate of the ink supplied to the recording head constant. 下面将描述用于控制从油墨室512向泡沫材料室511输送油墨的结构。 Structure will be described below for controlling the delivery chamber 512 from the ink chamber 511 to the foam material.

下面参见图9,该图表示本发明第三个实施例的泡沫材料室511和油墨室512之间的界面。 Referring now to Figure 9, which shows the interface between the third foam chambers 511 and the ink chamber 512 of the embodiment of the present invention. 用同样的标号表示同样的结构。 It represents the same structure with the same reference numerals. 这个实施例与第一个实施例之间的主要不同在于在孔519中形成的一个台阶部分。 The main difference between this embodiment and the embodiment of the first embodiment in that a stepped portion formed in the hole 519.

在通过519中形成一个台阶部分560。 519 formed by a step portion 560. 油墨室512的底部分563比泡沫材料室511的底部分高,台阶部分560是分隔中心。 Bottom portion 512 of the ink chamber 563 is higher than the bottom portion of the foam chamber 511, the center of the stepped portion 560 is separated. 连通泡沫材料室和油墨室的槽561是在台阶部分560的下部分内形成的。 Groove 561 communicates foam chamber and an ink chamber is formed in the lower portion 560 of the stepped portion.

多孔件520与连通孔519接触并挤入台阶部分560,这样,连通孔519附近的这部分多孔件520受到压缩,从而,通过连通孔519在油墨室512和泡沫材料室511之间获得了所需的压差。 The porous member 520 contacts with the communication hole 519 and squeeze the stepped portion 560, so that the vicinity of the communication hole 519 which portion of the porous member 520 is compressed, thereby, obtained through the communication hole 519 of the chamber 512 between the ink chamber 511 and the foam material required differential pressure. 当油墨室512内的油墨量减少到低值时,槽561使油墨室512内的油墨汇聚,然后被泡沫材料室511内的多孔件520吸收。 When reducing the amount of ink in the ink chamber 512 to a low value, the ink tank 561 in the ink chamber 512 converge, and then absorbed by the porous member 520 within the foam material chamber 511. 因此,油墨室512内的全部油墨都能毫无浪费地供给记录头进行打印。 Thus, all of the ink in the ink chamber 512 can be supplied to the recording head without waste printing.

现在参见图10,该图表示按照本发明的第四个实施例构成的墨盒。 Referring now to FIG. 10, which shows the ink cartridge constructed in accordance with a fourth embodiment of the present invention. 同样,用同样的标号表示同样的结构。 Likewise, the same structure represented by the same reference numerals. 这个实施例与第一个实施例之间的主要不同在于相应的室的底的高度不同。 The main difference between this embodiment and the embodiment of the first embodiment in that the different heights corresponding to the bottom of the chamber.

油墨室512的底表面564比泡沫材料室511的底表面高,从而形成台阶部分562。 A bottom surface of the ink chamber 564 512 higher than the bottom surface of the foam material chamber 511, thereby forming a step portion 562. 台阶部分562容纳多孔件520的下面部分。 Receiving the stepped portion 562 of the lower portion of the porous member 520. 这样,通过孔519附近的那部分多孔件受到压缩。 Thus, by the porous member compressed by the portion 519 near the aperture. 根据需要,可以形成从油墨室512向泡沫材料室511倾斜的斜面563,以促使油墨的输送。 If necessary, may be formed inclined surface 563 is inclined from the ink chamber 512 to the foam chamber 511, to cause the delivery of the ink. 由于斜面563可使油墨室512内的油墨较容易地流向泡沫材料室,与滑动架的倾斜无关,所以可从油墨室512稳定地供给记录头油墨。 Because ramp 563 allows the ink in the ink chamber 512 to flow relatively easily foam chamber, irrespective of the tilt of the carriage, it is possible to stably supply the ink from the ink chamber of the recording head 512.

现在参见图11和图12,这个图表示按照本发明第五个实施例构成的油墨盒。 Referring now to FIG. 11 and FIG. 12, the view showing an ink cartridge constructed in accordance with a fifth embodiment of the present invention. 同样的结构用同样的标号表示。 The same configuration denoted by the same reference numerals. 这个实施例与第一个实施例之间的主要不同在于通孔的形状。 The main difference between this embodiment and the embodiment of the first embodiment in that the shape of the through-hole. 这个实施例与图4和图5所示的实施例相同。 Example embodiment shown in FIG. 4 and FIG. 5 of this same embodiment.

在隔开泡沫材料室511和油墨室512的中部隔板510的表面上形成图4和图5所示的狭槽519a。 Slot 519a is formed as shown in FIG. 4 and FIG. 5 in the middle of the upper surface of the foam spacer 510 is spaced from the ink chamber 511 and the chamber 512. 狭槽519a是在隔板510的泡沫材料室511一侧的表面上形成的,并与相应的室511,512内的中部隔板510的连通孔519的上部连通。 Slit 519a is formed on the side surface 511 of the separator chamber 510 of the foam material, and an upper communication hole 519 communicates with the central spacer 511, 512 within the respective chamber 510. 为了使空气从油墨室512进入泡沫材料室511并使这些室保持流体连通,在狭槽519a的下端内形成通孔519b。 In order to allow air into the foam material from the ink chamber 511 and chamber 512 in fluid communication with the chamber, the through hole 519b is formed in the lower end of the slot 519a. 因此,具有较小毛细作用力的多孔件520的上部分通过由浅槽519a形成的空间与连通孔519保持流体连通。 Thus, the upper portion of the porous member 520 has a smaller capillary force through a space 519 in fluid communication with the communication hole 519a is formed by a shallow groove. 因而,空气能流畅地取代油墨,以使油墨室512内的油墨平衡地流入泡沫材料室511,从而防止供给油墨时出现过多或不足。 Thus, air can smoothly replace the ink, so that ink in the ink chamber 512 flows into the foam material balance chamber 511, thereby preventing excessive or insufficient supply of the ink occurs.

现在参见图13和图14,这两个图表示按照本发明的第六个实施例构成的油墨盒。 Referring now to FIGS. 13 and 14, these figures showing an ink cartridge constructed in accordance with a sixth embodiment of the present invention. 用同样的标号表示同样的结构。 It represents the same structure with the same reference numerals. 主要不同在于有一个伸入泡沫材料室511的凸出部。 The main difference is that there is a projecting portion extending into foam chamber 511.

如图14所示,在泡沫材料室511的底上形成一个马蹄形凸出部565。 14, a horseshoe-shaped projection 565 is formed on the bottom of the foam chamber 511. 凸出部565在连通孔519附近获得一个空间,以使油墨能易于从油墨室512流入泡沫材料室511。 The projecting portion 565 to obtain a space in the vicinity of the communication hole 519, so that the ink can easily flow into the foam chamber 511 from the ink chamber 512.

如上所述,一块中部隔板510将泡沫材料室511与油墨室512相互隔开。 As described above, a central spacer 510 and the foam chamber 511 of the ink chamber 512 spaced from each other. 分别如图5和图6所示,在单色墨盒的第七个或第八个实施例中,可使形成的油墨室571围绕着泡沫材料室570的两个或三个边,在隔开泡沫材料室570和油墨室571的壁572中的至少一个壁上,形成连通孔573。 5 and 6, respectively, in the seventh or eighth embodiment of the monochromatic ink cartridge, the ink chamber 571 can be formed around two or three sides of the foam chamber 570 in spaced foam chamber 570 and the ink chamber walls 572,571 in at least one wall, the communication hole 573 is formed. 在泡沫材料室570内有一个出口574。 An outlet chamber 574 within the foam material 570. 这个结构的墨盒能够储存的油墨量与整个墨盒的容积相比比较多。 The amount of ink cartridges can be stored configuration compared to the relatively large volume of the entire cartridge. 因而,由于室的位置的关系,用户易于查看因油墨用尽是否需要更换墨盒。 Thus, the relationship between the position of the chamber, the user is easy to see because of the need to replace the ink cartridges run out of ink.

现在参见图17和图18,这两个图表示按照本发明的第九个实施例构成的喷墨打印机的墨盒。 Referring now to FIGS. 17 and 18, these figures showing the ink cartridge of the ink jet printer constructed in accordance with a ninth embodiment of the present invention. 这个实施例怀第一个实施例类似,主要不同在于采用了弹性O形圈5300,在将供墨针状体插入供墨盒时,O形圈5300与记录头的供墨针状体的圆周表面接触。 Example pregnant embodiment similar to the first embodiment of this embodiment, the main difference is the use of an elastomeric O-ring 5300, when the ink supply needle inserted into the ink supply, the circumferential surface of the ink supply needle of the O-ring 5300 and the recording head contact. 然而,这种喷墨打印机产生了已被第一个实施例解决了的其它一些问题。 However, ink jet printers produce a first other problems have been solved in the embodiment. 当将墨盒装到滑动架上和将供墨针状体插入墨盒时,产生大的摩擦力,从而在记录头和滑架上造成附加应力。 When the ink cartridge is attached to the carriage and the ink supply needle when the ink cartridge is inserted, a large frictional force, causing additional stress in the recording head and the carriage. 此外,O形圈5300的圆周边由墨盒本体5302支承。 In addition, the circular periphery of the O-ring 5300 is supported by the cartridge body 5302. 在将供墨针状体插入供墨盒内时,如果在墨盒和记录头的供墨针状体间出现轴线不重合,则很难安装墨盒。 When the ink supply needle is inserted into the ink cartridge, if the axis occurs between the ink supply needle of the recording head and the ink container do not overlap, it is difficult to install the ink cartridge. 进一步说,当具有盛装三种颜色的油墨的槽5304,5306和5308的一个三色油墨盒如图18所示形成一体时,如果墨盒和任一个供墨针状体轴线不重合,则很难将这样一个墨盒安装到记录上。 Further, when an ink having three colors containing grooves 5304,5306 and a tri-color ink container 5308 shown in Figure 18. When integrally formed, if any ink cartridge and one ink supply needle axis do not coincide, it is difficult to such an ink cartridge is mounted to the recording.

因此,将会看到,从前面的描述中已变得明显的上述目的能得以有效地实现,由于在不脱离本发明的原则和范围的情况下实现上面的结构和所述的方法时可以作某些改变,所以上面的描述所包含的和附图所示的内容应被理解为是说明性的而没有限制的舍义。 Thus, it will be seen from the foregoing description has become evident object described above can be effectively realized, can be realized due to the above structure and the method without departing from the spirit and scope of the present invention certain changes, the above description and accompanying drawings is included as shown is to be understood as illustrative and not in a limiting sense homes.
