摘要： The present invention is an ink pressure adjustment device of inkjet pen; the device is utilized to adjust negative pressure in an ink cartridge mainly through an expandable and shrinkable gasbag installed in the ink cartridge, and a tension valve attached on the surface of the gasbag. The tension valve can open or close automatically an air hole that communicates atmosphere and the inner part of ink cartridge via the gasbag according to the expansion and shrinkage of the gasbag, causing a part of atmosphere to enter the ink cartridge so as to adjust the negative pressure of the ink cartridge and not only can prevent ink from leaking but also prevent the negative pressure from being too large to fail the inkjet printing.

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： The ink cartridge of the present invention uses a directional fibrous collection enclosed within a bushing to temporally retain the ink therein, wherein at least one controlled capillary portion is provided. The controlled capillary portion can be formed by the bushing or by a predetermined shape located in the cartridge. The capillary forces of the controlled capillary portion are stronger than the one of other portion of the directional fibrous collection. The flow rate of the ink can be precisely controlled by the directional fibrous collection, and the controlled capillary portion can efficiently drain out the ink to the printhead and there is no bubble left therein.

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： 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： 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.

摘要： An ink storage unit comprises an ink tank that defines an inner confinement space in which is placed an ink storage body to store and retain ink. The ink tank includes an air inlet through which air passage in the ink tank is enabled, and an ink outlet through which ink output is achieved. An outer surface of the ink storage body includes a plurality of notches distributed along an interface between the ink storage body and the ink tank, thereby forming a plurality of gaps that locally separate the outer surface of the ink storage body from the sidewall of the ink tank. Alternatively, the ink storage body is comprised of a first ink storage portion that is separated from a second ink storage portion via a spacing member. Ink flowing and leakage through the air inlet is thereby prevented.
