Problems solved by technology

[0008] The above two devices can be found in U.S. Patents No. 5,526,030, 6,186,620, and 6,213,598. However, the negative pressure regulators disclosed in these patents all need to use more than two components to achieve the function of negative pressure regulation. Therefore, it has the disadvantages of complex structure, inconvenient manufacture, and affecting the space for storing ink in the ink cartridge. Therefore, a liquid-air interface maintenance device is designed to achieve the function of negative pressure adjustment through a relatively small number of components, and increase the manufacturing cost. Convenience and increased ink storage space

Embodiment Construction

[0027] The liquid-air interface maintenance device disclosed according to the present invention is applied to the ink cartridge 1, such as figure 1 and figure 2 As shown, the liquid-air interface maintenance device is arranged at the bottom of the ink cartridge 1, and includes an air supply hole 10 and an ink collection groove 20. The ink collection groove 20 is arranged at the bottom of the ink cartridge 1, and the air supply hole 10 is also arranged at the bottom of the ink cartridge 1. bottom, and make the outside of the ink cartridge 1 communicate with the ink collection tank 20, the ink communicates with the air supply hole 10 and the ink collection tank 20 by capillary force, and forms an air supply channel (liquid-air interface) between the air supply hole 10 and the outside of the ink cartridge 1 , and the ink attached to the ink collecting tank 20 can ensure the supply of ink in the air supply hole 10, so the air supply channel that the ink cartridge 1 communicates w...

Abstract

The liquid-gas interface maintaining device for ink cartridge has air replenishing hole, which is set in the ink cartridge and communicated with the ink collecting tank. By means of capillary phenomenon, ink from the ink cartridge is filled into the air replenishing hole and attached to the surface of the ink collecting tank to form the liquid-gas interface as the air replenishing passage between the ink cartridge and the outer gas. The air replenishing passage prevents outer gas from entering the ink cartridge improperly so as to maintain proper negative pressure inside the ink cartridge.

Description

technical field [0001] The invention relates to a liquid-gas interface maintaining device, which is applied to an ink cartridge of an inkjet printer to maintain a proper negative pressure inside the ink cartridge. Background technique [0002] Inkjet printers are already a fairly reliable and efficient printing tool. Typically, an inkjet printer has an inkjet print head that traverses relative to a printing surface and ejects ink droplets. A control system moves the inkjet printing head to an appropriate position and then makes it eject ink droplets, and the ink droplets fall on the printing surface to form the desired image or data content. An ink pen is usually used in this type of printer, which mainly includes two parts such as an ink cartridge for storing and supplying ink and an inkjet printing head. [0003] The inkjet printing head is usually provided with a plurality of microholes, and each microhole has its own connected ink cavity...
