摘要： The ink cartridge is provided with a pressure controller to regulate the inner pressure therein by atmospheric pressure while the ink stored in the ink cartridge is gradually drained off. The ink is stored in a container with negative pressure therein, and at least one through hole formed on the container is used to connect to the atmosphere, and at least one recess is formed on the inner wall of the through hole. The pressure controller has a plug movably disposed on the through hole and the recesses. The recesses are used as a channel to allow the entrance of the atmospheric air, and the plug can be automatically moved so as to enlarge the clearance between the plug and the through hole while the ink stored in the ink cartridge is gradually drained off. The inputted air can effectively reduce the negative pressure in the container, and therefore the printing process of the ink cartridge can be proceeding steadily.
摘要翻译：墨盒设置有压力控制器，以在储存在墨盒中的墨水逐渐排出时通过大气压来调节其内部压力。油墨存储在其中具有负压的容器中，并且使用形成在容器上的至少一个通孔连接到大气，并且在通孔的内壁上形成至少一个凹部。压力控制器具有可移动地设置在通孔和凹部上的插头。这些凹槽用作允许大气进入的通道，并且插头可以被自动移动，以便当存储在墨盒中的墨水逐渐排出时，扩大插头和通孔之间的间隙。输入的空气可以有效地减少容器中的负压，因此墨盒的打印过程可以稳定地进行。

摘要： The present invention provides a pressure control apparatus for an ink-jet pen. The apparatus will adjust the back pressure of ink in the reservoir of the ink-jet pen in a suitable range when the ink is used gradually. The apparatus includes a pressure adjusting element and a hole furnished on the bottom wall of a reservoir. Under normal condition, the pressure adjusting element contacts tightly to the hole and prevents air from ingression. When the back pressure increases gradually to an extent, the ambient air will overcome the pressure of a spring which provides force to the pressure adjusting element, thus move the pressure adjusting element to leave a clearance to the hole and let some air bubbles ingressing into the reservoir till the back pressure decreases to a certain value. After the back pressure returns to the certain value, the pressure adjusting element further contacts the hole and prevents air from ingression, thus maintains a suitable back pressure of the ink in the reservoir.
摘要翻译：本发明提供一种用于喷墨笔的压力控制装置。当墨水逐渐使用时，该装置将在喷墨笔的储存器中的墨水的背压调节在合适的范围内。该装置包括压力调节元件和设置在储存器的底壁上的孔。在正常情况下，压力调节元件紧紧接触孔，防止空气进入。当背压逐渐增加到一定程度时，环境空气将克服向压力调节元件提供力的弹簧的压力，从而移动压力调节元件以留下孔，并使一些气泡进入水库直到背压降到一定值。在背压返回到一定值之后，压力调节元件进一步接触孔并防止空气进入，从而保持油墨在油箱中的合适的背压。
