喷墨打印设备主要依靠墨水形成文字或者图像，而墨水主要由安装于喷墨打印设备内的墨盒来提供。市面上的墨盒主要分为两大类：打印头墨盒和非打印头墨盒。大部分打印头墨盒都在墨腔内收容有海绵，并通过海绵吸纳墨水，这种墨盒的含墨量较少，因此打印成本较高。然而，这种墨盒的墨水耗尽后，打印头的寿命并未随之终止，因此，有人利用这种墨盒改制成连续供墨系统，以使墨盒的使用寿命得到延长。Inkjet printing devices rely primarily on ink to form text or images, while ink is primarily provided by an ink cartridge that is mounted in an inkjet printing device. There are two main types of ink cartridges on the market: printhead cartridges and non-printhead cartridges. Most of the printhead cartridges contain a sponge in the ink chamber and absorb ink through the sponge, which has a low ink content and therefore has a high printing cost.

图1是应用本发明实施例的连续供墨系统的示意图。 BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic illustration of a continuous ink supply system to which embodiments of the present invention are applied.
参见图1，本实施例的连续供墨系统包括安装在打印机内的打印头墨盒1以及外置于打印机的供墨瓶3，打印头墨盒1初始状态是不含有墨水的，但墨腔内容纳有海绵12，墨腔底部具有出墨口14。打印头墨盒1上还设有注墨口15，该注墨口15可以是墨盒原来的气口或对气口略为加工而成。该注墨口15与输墨管2的第一端部密封连接。输墨管2的第二端部与设置于供墨瓶3底部的供墨口31密封连接。供墨瓶3内容纳有墨水，其容量数倍甚至数十倍于打印头墨盒1的墨水容量。供墨瓶3的顶部设置有气口32和灌墨口33。气口32和灌墨口33的位置高于供墨瓶3内墨水的液面，目的是避免供墨瓶内的液体在后续抽负压的过程中被抽出。Referring to Fig. 1, the continuous ink supply system of the present embodiment comprises a print head ink cartridge 1 installed in a printer and an ink supply bottle 3 externally disposed in the printer. The ink cartridge 1 of the print head is initially free of ink, but the ink chamber is contained therein. There is a sponge 12 having an ink outlet 14 at the bottom of the ink chamber. The inkjet cartridge 15 is further provided with an ink filling port 15, which may be a raw air port of the ink cartridge or a slightly processed air port. The ink filling port 15 is sealingly connected to the first end of the ink feed tube 2. The second end of the inking tube 2 is sealingly connected to the ink supply port 31 provided at the bottom of the ink supply bottle 3. The ink supply bottle 3 contains ink, which has a capacity several times or even several times the ink capacity of the print head cartridge 1. The top of the ink supply bottle 3 is provided with a gas port 32 and an ink filling port 33. The position of the port 32 and the ink filling port 33 is higher than the liquid level of the ink in the ink supply bottle 3, in order to prevent the liquid in the ink supply bottle from being withdrawn during the subsequent suction of the negative pressure.
本连续供墨系统的制造方法如下：提供一个输气管4，将输气管4的第一端部与灌墨口33密封连接，第二端部与一个过滤腔5密封连接，而过滤腔5与一个负压产生装置密封连接。即，所述过滤腔5密封连接在所述供墨瓶3和所述负压产生装置之间。该负压产生装置可用真空泵、微型真空泵或者其他具有产生负压的工具或者设备。在本实施例中，该负压产生装置为微型真空泵6。该微型真空泵6可通过电脑USB接口或手机充电设备供电，供电电压为5V。用密封组件13密封打印头墨盒上的出墨口14，并用密封薄膜密封供墨瓶的气口32，若出墨口14和气口32已处于密封状态，可省略此步骤。启动微型真空泵6，由于连续供墨系统的内腔完全与外界大气隔绝，因此，供墨瓶3内的气体以及打印头墨盒1内的气体通过灌墨口33逐渐被抽出腔体，而抽出的空气中所含有的墨水等杂质将会在过滤腔5中被过滤。当腔体中的负压值达到预定值时，停止抽负压。在本实施例中，负压值达到60Kpa时，停止抽负压。然后将输气管4与灌墨口33之间的密封连接断开，此时，灌墨口33暴露于大气中，由于大气压的作用，供墨瓶内的部分墨水通过输墨管2被压入打印头墨盒1内，压入的墨水会占据被抽出的气体的空间，之后用密封胶塞密封该灌墨口33。上述步骤完成后，用户只需除去出墨口14的密封件13，同时除去气口32的密封薄膜，将墨盒1安装于打印设备内的墨盒收容部中，该连续供墨系统即可正常工作。依据本发明所制造的连续供墨系统，其墨盒内残留的空气较少，这样就降低了打印时产生白斑现象的可能性。The continuous ink supply system is manufactured as follows: a gas supply pipe 4 is provided, the first end of the gas pipe 4 is sealingly connected to the ink filling port 33, and the second end is sealedly connected to a filter chamber 5, and the filter chamber 5 is A vacuum generating device is sealingly connected. That is, the filter chamber 5 is sealingly connected between the ink supply bottle 3 and the negative pressure generating device. The vacuum generating device may be a vacuum pump, a micro vacuum pump or other tool or device having a negative pressure. In the present embodiment, the negative pressure generating device is a micro vacuum pump 6. The micro vacuum pump 6 can be powered by a computer USB interface or a mobile phone charging device, and the power supply voltage is 5V. The ink outlet 14 on the print head cartridge is sealed by a sealing member 13, and the ink port 32 of the ink supply bottle is sealed with a sealing film. If the ink outlet port 14 and the gas port 32 are already in a sealed state, this step can be omitted. The micro vacuum pump 6 is activated. Since the inner cavity of the continuous ink supply system is completely isolated from the outside atmosphere, the gas in the ink supply bottle 3 and the gas in the print head ink cartridge 1 are gradually drawn out of the cavity through the ink filling port 33, and the drawn air is extracted. Impurities such as ink contained in the air will be filtered in the filter chamber 5. When the negative pressure value in the chamber reaches a predetermined value, the suction negative pressure is stopped. In the present embodiment, when the negative pressure value reaches 60 kPa, the suction negative pressure is stopped. Then, the sealing connection between the gas pipe 4 and the ink filling port 33 is broken. At this time, the ink filling port 33 is exposed to the atmosphere, and part of the ink in the ink supply bottle is pressed through the ink feeding tube 2 due to the atmospheric pressure. In the print head cartridge 1, the pressed ink occupies a space of the extracted gas, and then the ink fill port 33 is sealed with a sealant. After the above steps are completed, the user only needs to remove the sealing member 13 of the ink outlet port 14, and at the same time remove the sealing film of the air port 32, and install the ink cartridge 1 in the ink cartridge accommodating portion in the printing device, and the continuous ink supply system can work normally. According to the continuous ink supply system manufactured by the present invention, less air remains in the ink cartridge, which reduces the possibility of white spots on printing.
在上述制造过程中，用于从供墨瓶抽负压及卸负压的开口是可以更换的。例如，将输气管的第一端部与供墨瓶的气口密封连接，并使用密封胶塞密封供墨瓶的灌墨口，则负压产生装置就能从气口进行抽负压和卸负压的工序。又例如在供墨瓶的顶端新开设一个开口，将输气管的第一端部与新开设的开口密封连接，并同时密封灌墨口和气口，则负压产生装置就能从这个新开设的开口进行抽负压和卸负压的工序。In the above manufacturing process, the opening for drawing the negative pressure and the negative pressure from the ink supply bottle is replaceable. For example, by sealing the first end of the gas pipe to the mouth of the ink supply bottle and sealing the ink supply port of the ink supply bottle with a sealing plug, the negative pressure generating device can perform negative pressure and negative pressure from the gas port. Process. For example, a new opening is formed at the top end of the ink supply bottle, and the first end of the gas pipe is sealedly connected with the newly opened opening, and at the same time, the ink filling port and the gas port are sealed, and the negative pressure generating device can be newly opened from the new one. The opening performs a process of suctioning negative pressure and discharging negative pressure.
另外，现有的部分供墨瓶结构，其顶端只有一个开口，该开口既可以实现灌墨口的功能，也可以实现气口的功能。对于这种结构的连续供墨系统，在制造过程中，只需将输气管的第一端部与此开口密封连接，负压产生装置就能进行抽负压和卸负压的工序。In addition, the existing partial ink supply bottle structure has only one opening at the top end, and the opening can realize the function of the ink filling port and the function of the air port. In the continuous ink supply system of such a structure, in the manufacturing process, the first end portion of the gas pipe is only required to be sealingly connected to the opening, and the negative pressure generating device can perform the steps of suctioning negative pressure and discharging negative pressure.
在上述制造过程中，抽负压的负压值是可以选择的。本例的负压值为-60KPa，其原因是：首先，常用的微型真空泵可轻易的达到60Kpa的负压值；其次；由于抽负压是一个过程，在这个抽负压的过程中，墨盒内的气体是会逐渐排出，当负压值达到60KPa时，已经能够保证较好的排气效果。当然，根据多次实验的结果来看，当负压值的范围在-50Kpa至-100Kpa之间时，均能够实现本发明的目的。而负压值超过-60Kpa并接近-100Kpa时，排气效果固然更好，但对供墨瓶及墨盒的材质要求也更高，否则过大的负压可能导致供墨瓶或墨盒的变形甚至损坏。另一方面，当负压值远小于-50Kpa时，排气效果不明显，墨盒内仍残留了较多气体，打印白斑的现象仍然会比较频繁。综上所述，本发明优选的负压值的范围在-50Kpa至-100Kpa，更优选的负压值为-60Kpa。In the above manufacturing process, the negative pressure value of the negative pressure is selectable. The negative pressure value of this example is -60KPa, the reason is: First, the commonly used micro vacuum pump can easily reach the negative pressure value of 60Kpa; secondly; because the negative pressure is a process, in this process of vacuuming, the ink cartridge The gas inside will be gradually discharged, and when the negative pressure value reaches 60KPa, the better exhaust effect can be ensured. Of course, according to the results of a plurality of experiments, the object of the present invention can be achieved when the range of negative pressure values is between -50 Kpa and -100 Kpa. When the negative pressure value exceeds -60Kpa and is close to -100Kpa, the exhaust effect is better, but the material requirements for the ink supply bottle and the ink cartridge are also higher. Otherwise, the excessive negative pressure may cause the deformation of the ink supply bottle or the ink cartridge or even damage. On the other hand, when the negative pressure value is much smaller than -50Kpa, the exhaust effect is not obvious, and more gas remains in the ink cartridge, and the phenomenon of printing white spots is still relatively frequent. In summary, the preferred negative pressure value of the present invention ranges from -50 kPa to -100 kPa, and more preferably the negative pressure value is -60 kPa.
本发明连续供墨系统的制造方法简单，其不仅仅适用于具有打印头的海绵墨盒的制造，也适用于具有打印头的无海绵墨盒，甚至非打印头墨盒的制造。The continuous ink supply system of the present invention is simple in its manufacture, and is not only suitable for the manufacture of a sponge cartridge having a printhead, but also for the manufacture of a spongeless cartridge having a printhead or even a non-printhead cartridge.
根据本发明提供的连续供墨系统的制造方法，抽负压时，墨盒内残留的部分气体会被抽吸到供墨瓶中，并最终被排出供墨瓶。卸负压时，供墨瓶内的部分墨水通过输墨管被压入墨盒内，压入的墨水占据先前气体的空间，因此墨盒内残留的空气大为减少，这样就降低了打印时产生白斑现象的可能性。 According to the method of manufacturing a continuous ink supply system provided by the present invention, when a negative pressure is applied, a part of the gas remaining in the ink cartridge is sucked into the ink supply bottle and finally discharged to the ink supply bottle. When the negative pressure is unloaded, part of the ink in the ink supply bottle is pressed into the ink cartridge through the ink pipe, and the pressed ink occupies the space of the previous gas, so the residual air in the ink cartridge is greatly reduced, thereby reducing the white spot on the printing. The possibility of a phenomenon.
