Abstract: 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.

Abstract: 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.

Abstract: An ink container includes a housing, a print head, and a fluid chamber. The housing has two inclined walls formed to divide the fluid chamber into a center ink well and two side ink wells. The housing also has two side walls, each having an inclined inner surface. The center ink well is formed between the two inclined walls. Each side ink well is formed between an inclined wall and a side wall. The inner surface of each side wall has a greater inclination than those of the inclined walls, so that each side ink well has a width decreasing from top to bottom.

Abstract: An inkjet pen and a manufacturing method thereof. The inkjet pen includes a body, a side plate, an elastic member, and a dividing plate. The side plate is combined with the body. The elastic member is disposed in the body. The dividing plate is disposed in the body in a manner such that the dividing plate abuts the elastic member. A gap is formed between the dividing plate and the side plate.

Abstract: An inkjet pen and a pressure control device thereof. The inkjet pen comprises a body, a bag, a pressure plate, an abutting member, and a rib. The body includes a bubble generator. The bag is disposed inside the body, and communicates with the external environment so as to expand inside the body. The pressure plate, disposed inside the body and located adjacent to the bag so as to move inside the body, includes a first portion and a second portion. The first portion is located near the bubble generator. The abutting member is disposed in the body, and seals the bubble generator. The rib is disposed in the body and located near the second portion of the pressure plate. The second portion of the pressure plate is maintained at a predetermined position by the rib when the pressure plate is moved by the bag. Thus, the abutting member is properly moved by the first portion of the pressure plate when the pressure plate is moved by the bag.

Abstract: 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.
