Description
技术领域technical field
本发明涉及一种喷墨打印机墨盒使用的密封件。The invention relates to a seal used in ink cartridges of ink jet printers.
背景技术Background technique
目前市场上的微压电式打印机墨盒，使用的密封件几乎只有密封打印机供墨针的作用，没有墨盒脱离打印机后防止墨水从出墨口流出。如果需要实现这一功能，必须要增加出墨口的阀机构，包括一个弹性元件及一个阀芯，这样就增加墨盒的零配件，并且装配工艺复杂，增加了墨盒的使用成本。The micro-piezoelectric printer ink cartridges currently on the market almost only have the function of sealing the ink supply needle of the printer, and there is no ink cartridge to prevent ink from flowing out from the ink outlet after the ink cartridge is separated from the printer. If this function needs to be realized, it is necessary to increase the valve mechanism of the ink outlet, including an elastic element and a valve core, so that the spare parts of the ink cartridge are increased, and the assembly process is complicated, which increases the use cost of the ink cartridge.
本发明内容Contents of the invention
针对以上传统墨盒的传统密封件结构的问题或缺陷而创立了本发明。因此，本发明的目的是提供一种用于喷墨打印机墨盒的密封件，它能够在墨盒安装在打印机上时密封住打印机的供墨针，墨盒从打印机上取下时，可以防止墨水从出墨口泄漏出来。The present invention is made in view of the above problems or defects of the conventional seal structure of the conventional ink cartridge. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a seal for an ink-jet printer ink cartridge which is capable of sealing the ink supply needle of the printer when the ink cartridge is mounted on the printer, and which prevents ink from coming out when the ink cartridge is removed from the printer. The ink port leaks out.
一种喷墨打印机墨盒使用的密封件，包括用于密封墨盒的出墨口的密封端，其特征在于：所述密封件为圆柱形状，密封件的内部有一个圆柱型的空腔，该空腔的直径尺寸大于打印机的供墨针的直径尺寸。A seal used in an ink-jet printer cartridge, comprising a sealing end for sealing the ink outlet of the ink cartridge, characterized in that: the seal is cylindrical, and there is a cylindrical cavity inside the seal. The diameter dimension of the cavity is larger than the diameter dimension of the ink supply needle of the printer.
所述用于密封墨盒的出墨口的密封端为圆柱面，一个端面是可以防止墨盒脱离打印机后墨水从出墨口流出的封闭平面，另一个端面是中间有一个小孔的平面，所述小孔的尺寸可以密封打印机的供墨针。或者，The sealing end used to seal the ink outlet of the ink cartridge is a cylindrical surface, one end surface is a closed plane that can prevent ink from flowing out of the ink outlet after the ink cartridge is separated from the printer, and the other end surface is a plane with a small hole in the middle. The small holes are sized to seal off the printer's ink supply needles. or,
所述用于密封墨盒的出墨口的密封端为在圆柱面上至少有一圈密封凸缘，一个端面是可以防止墨盒脱离打印机后墨水从出墨口流出的封闭平面，另一个端面是中间有一个小孔的平面，所述小孔的尺寸可以密封打印机的供墨针。The sealing end used to seal the ink outlet of the ink cartridge is at least a ring of sealing flanges on the cylindrical surface, one end surface is a closed plane that can prevent the ink from flowing out of the ink outlet after the ink cartridge is separated from the printer, and the other end surface is a sealing surface in the middle. The plane of a small hole sized to seal the printer's ink supply needles.
构成端面b及其封闭平面或至少允许供墨针穿越的封闭平面的一部分材质为弹性可收缩的，例如橡胶、硅胶等弹性材料，保证墨盒从打印机上取下来时，供墨针穿越的部分又自动地封闭，防止墨水从出墨口中泄漏出。The material constituting the end face b and its closed plane or at least a part of the closed plane that allows the ink supply needle to pass through is elastically shrinkable, such as elastic materials such as rubber and silica gel, to ensure that when the ink cartridge is removed from the printer, the part that the ink supply needle passes through again Automatically closes to prevent ink from leaking out of the ink outlet.
由于本发明采用了上述技术方案，从而使密封件的结构极其简单，不仅能够在墨盒安装在打印机上时密封住打印机的供墨针，墨盒从打印机上取下时，可以防止墨水从出墨口泄漏出来，本发明装配工艺简单，可降低墨盒的成本。Because the present invention adopts the above-mentioned technical scheme, the structure of the sealing member is extremely simple, which not only can seal the ink supply needle of the printer when the ink cartridge is installed on the printer, but also prevent the ink from flowing out of the ink outlet when the ink cartridge is removed from the printer. leak out, the invention has a simple assembly process and can reduce the cost of the ink cartridge.

以下结合具体实施方式及其附图对本发明作进一步说明：The present invention will be further described below in conjunction with specific embodiment and accompanying drawing:
如图1所示为密封件的一种剖面视图，圆柱面上面有两圈凸缘4，用来密封墨盒的出墨口8(图2)，6为端面b，是一个封闭平面，装机时打印机的供墨针从端面穿过，通过空腔5，从端面中间的小孔2穿出来。3为端面a，其中间的小孔用来密封打印机的供墨针，其尺寸可以密封打印机的供墨针，而密封件1内部的空腔5的直径尺寸大于打印机的供墨针直径。当墨盒从打印机上取下来时，端面b又自动地封闭，防止墨水从出墨口中泄漏出。As shown in Figure 1, it is a cross-sectional view of the seal. There are two rings of flanges 4 on the cylindrical surface, which are used to seal the ink outlet 8 of the ink cartridge (Figure 2), and 6 is the end face b, which is a closed plane. The ink supply needle of the printer passes through the end face, passes through the cavity 5, and passes through the small hole 2 in the middle of the end face. 3 is the end surface a, the small hole in the middle is used to seal the ink supply needle of the printer, and its size can seal the ink supply needle of the printer, and the diameter of the cavity 5 inside the sealing member 1 is larger than the diameter of the ink supply needle of the printer. When the ink cartridge is taken off from the printer, the end face b is automatically closed again to prevent ink from leaking out of the ink outlet.
显然，构成端面b及其封闭平面或至少允许供墨针穿越的封闭平面的一部分材质为弹性可收缩的，例如橡胶、硅胶等弹性材料，保证墨盒从打印机上取下来时，供墨针穿越的部分又自动地封闭，防止墨水从出墨口中泄漏出。Obviously, the materials constituting the end face b and its closed plane or at least a part of the closed plane that allows the ink supply needle to pass through are elastically shrinkable, such as elastic materials such as rubber and silica gel, so as to ensure that the ink supply needle passes through when the ink cartridge is removed from the printer. The part is automatically closed again to prevent ink from leaking from the ink outlet.
