Definitions

  • the invention relates to an ink cartridge for inkjet printers.
  • ink cartridges have the following disadvantages: the porous substance and the fiber take up some space within the ink tank, which reduces the pressure yield. A certain amount of ink remains in the porous substance and the fibers. Ink is so wasted, which is also not good for the environment. The ink also tends to leak out of the dispensing port after use of the cartridge.
  • the invention has for its object to provide an easy to manufacture and highly efficient ink cartridge for printers.
  • This new ink cartridge is designed to ensure reliable and consistent dispensing of the ink and to control the execution of the printing process.
  • an ink supply system which consists of a thin and long fiber around the ink outlet opening, a lever extending from top to bottom and consisting of an elastic part or material and a capillary tube running in the manner of a labyrinth.
  • the thin and long fiber is joined from the tip to the end and extends to the ink outlet opening, which is firmly fixed in the cartridge.
  • the capillary tube running in the manner of a labyrinth and the associated arrangement guarantee that the ink cannot get to the thin and long fiber under normal or initial conditions.
  • the lever attached to the cartridge consists of an elastic component that is assembled from the tip to the end.
  • the initial section of the labyrinthine capillary tube is located at the lowest point of the ink tank.
  • the new ink cartridge can ensure a reliable and even supply of ink and evenly control the execution of the printing process.
  • the ink cartridge includes an air labyrinth, an arrangement that protects against ink leakage, a labyrinthine capillary tube, a thin and long fiber, an ink tank, a lever, etc.
  • the air labyrinth Before the When the cartridge is inserted into the printer, the air labyrinth must be opened. The air enters the ink tank through the ink leak-preventing assembly. There is normal air pressure in the ink tank. After installing the ink cartridge, the thin, long fiber presses firmly against the nozzle of the print head. In the meantime, the outlet opening of the cartridge and the print head are sealed. When printing begins, the thin and long fiber supplies the printhead with ink evenly. The ink could get into the fiber from the ink tank through the labyrinthine capillary tube due to the pressure, which also guarantees the correct amount of ink within the fiber. The air enters the ink tank through the air labyrinth.
  • the pressure inside the ink tank is advantageously kept in a narrow, limited range, which increases the pressure range or pressure yield and reduces the production costs. In addition, the consumption and especially the loss of ink is reduced, which also benefits the environment.
  • the new ink cartridge is well suited for mass production with guaranteed quality.
  • FIG. 2 shows the top view of the one narrow side of the cartridge, as shown in FIG. 1,
  • 3a shows the cartridge inserted in the holder of a printer
  • Fig. 3b shows a position of the ink cartridge while it is inserted in the holder of a printer
  • Fig. 4 shows a section through the ink cartridge inserted into the holder of a printer, seen from its other broad side.
  • the ink cartridge has, as components important for the invention, a lever 1, an ink container or ink tank 2, a capillary tube 3, which runs in the manner of a labyrinth, a thin and long fiber 4, an upper cover 5, an outlet opening 6, an arrangement 7, which prevents the ink from leaking
  • Air labyrinth 8 and an ink filling opening 9 in the form of a nozzle 9 on the print head Before the ink cartridge is inserted into the printer, the air labyrinth 8 must be opened. The air then flows into the ink tank 2 through the arrangement 7, which protects against ink leakage, and also maintains normal air pressure in the ink tank 2.
  • the thin and long fiber 4 presses firmly against the nozzle 9 of the print head.
  • the outlet opening 6 of the ink cartridge and the printhead is tightly closed in the meantime.
  • the thin and long fiber 4 feeds the ink evenly to the print head.
  • the ink tank 2 is under a slight air pressure, and the ink can reach the thin and long fiber 4 through the capillary tube 3 which winds in the manner of a labyrinth, which ensures the correct amount of ink content in the thin and long fiber 4 , The air passes through the air labyrinth 8 into the ink tank 2.

Abstract

L'invention concerne une cartouche d'encre pour imprimante à jeu d'encre, qui se caractérise en ce qu'elle comporte un système d'alimentation en encre comprenant une fibre longue et mince (4) autour de l'orifice de sortie de l'encre (6), un levier (1) à base d'une partie ou d'un matériau élastique, qui s'étend de haut en bas et un tube capillaire (3) s'étendant en labyrinthe. Cette nouvelle cartouche d'encre assure une alimentation régulière et fiable en encre et par conséquent une exécution homogène du processus d'impression. La pression régnant à l'intérieur du réservoir d'encre de la cartouche d'encre est maintenue dans une plage étroite, limitée, ce qui permet d'augmenter la portée et le rendement de l'impression, de réduire la consommation et avant tout les déperditions d'encre. Les coûts de production de la cartouche d'encre sont réduits et cette cartouche d'encre est bien adaptée à la production de masse, tout en garantissant une qualité élevée.
