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： 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： A pressure control device installed inside an ink reservoir. The ink reservoir further includes a pressure regulator. The pressure control device at least includes a nozzle stand, a plugging block and a spring-loaded structure. The nozzle stand is attached to the bottom wall of the ink reservoir. The nozzle stand further includes a nozzle hole for linking up the interior of the ink reservoir with the exterior. The nozzle stand has a groove near the upper end of the nozzle. The plugging block is placed inside the groove for partitioning the interior of the ink reservoir from the exterior. The spring-loaded structure has a first section and a second section that connect with each other. The first section presses against the outer edge of the plugging block with an elastic force. The pressure regulator pushes the second section and lifts the first section away from the outer edge of the plugging block. A limiting structure may also be installed somewhere crossing the path of movement of the spring-loaded structure so that the range of movement of the spring-loaded structure is confined.

摘要： An ink reservoir has an air bag, a housing with an ink reservoir, an elastic constraining device for constraining the air bag to prevent the seepage of ink by way of back-pressure, an active shaft movably installed in the ink reservoir, and a plugging device engaged with the active shaft for plugging a second vent of the housing. When consumption of ink in the ink reservoir causes the air bag to expand to a predetermined degree, the air bag moves the active shaft, the active shaft pulls the plugging device out of the second vent, and air enters into the ink reservoir to reduce the volume of the air bag.

摘要： An ink cartridge has a housing with an ink reservoir. The housing has a first vent, a second vent, and an opening. The ink reservoir has an air bag to adjust pressure within the ink reservoir. The ink cartridge further has an elastic restricting device that prevents ink in the ink reservoir from seeping through the opening. An elastic plug plugs the second vent of the housing, and an active shaft is movably installed in the well for pushing the elastic plug. When consumption of ink causes the air bag to expand to a predetermined degree, the air bag moves the active shaft, the active shaft pushes the elastic plug, and air enters into the ink reservoir through the second vent to reduce the volume of the air bag. When the air bag stops moving the active shaft, the elastic plug plugs the second vent.

摘要： An ink jet-printing apparatus includes an ink reservoir, a print head, a flexible pocket, and a resilient element. The print head is used for ejecting ink from the reservoir. The reservoir is substantially sealed so that ejection of ink from the reservoir decreases a pressure in the reservoir volume. The flexible pocket is disposed in the ink reservoir and is capable of slowing a decrease of the pressure in the reservoir volume by changing a reservoir volume of a reservoir cavity defined between the flexible pocket and the reservoir. The resilient element is disposed within the ink reservoir and the flexible pocket for maintaining the pressure in the reservoir volume below the ambient pressure. The flexible pocket and the resilient element regulate changes in the negative pressure of the ink-jet printing apparatus.
