    • 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.
    • 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。
