Said novel ink cartridge ensures a constant and reliable supply of ink and thus an evenly executed printing process. The pressure inside the ink reservoir of the ink cartridge is kept in a narrow, defined region, increasing the print capacity and yield, and reducing the consumption, and especially the loss, of ink. The invention enables the production costs of the ink cartridge to be reduced, and the inventive ink cartridge can be mass produced with a consistently high quality.

Description

Die Erfindung bezieht sich auf eine Tintenpatrone für Tintenstrahldrucker.The invention relates to an ink cartridge for ink jet printers.

Auf dem Markt sind zur Zeit zwei Typen von Tintenpatronen für Tintenstrahldrucker bekannt. Bei den einen kommen eine poröse Substanz oder Fiberbündel zur Anwendung, um zum einen das Auslecken von Tinte zu verhindern und zum anderen eine gleichmäßige Abgabe der Tinte zu erreichen. Die anderen benutzen ein Einweg-Ventil und eine den Druck justierende Anordnung mit Fiber innerhalb der Patrone, um die gleichmäßige Abgabe der Tinte zu steuern.There are currently two types of ink jet printer ink cartridges known in the market. Some use a porous substance or bundles of fibers to prevent ink leakage and to achieve uniform ink delivery. The others use a one-way valve and pressure-adjusting assembly with fiber inside the cartridge to control the even delivery of the ink.

Diese Tintenpatronen haben folgende Nachteile:

  • Die poröse Substanz und die Fiber beanschpruchen einigen Raum innerhalb des Tintenbehälters, wodurch der Druckertrag gemindert wird. Eine bestimmte Menge an Tinte verbleibt in der porösen Substanz und den Fibern. Tinte wird so vergeudet, was auch nicht gut für die Umwelt ist. Auch neigt die Tinte dazu, nach Gebrauch der Patrone aus der Abgabeöffnung auszulecken.
These ink cartridges have the following disadvantages:
  • The porous substance and the fiber occupy some space within the ink container, thereby reducing the print yield. A certain amount of ink remains in the porous substance and the fibers. Ink is wasted, which is not good for the environment. Also, the ink tends to leach out of the dispensing opening after use of the cartridge.

Aus der US6,419,350 ist ein Tintenbehälter mit einem Absorptionsglied zur Aufnahme von Tinte bekannt, wobei der Tintenbehälter weiterhin eine Pufferzone zur temporären Aufnahme der Tinte und einen zur Atmosphäre offenen Anschluss enthält.From the US6,419,350 For example, an ink container having an absorption member for receiving ink, the ink container further comprising a buffer zone for temporarily receiving the ink and a port open to the atmosphere.

Der Erfindung liegt die Aufgabe zugrunde, eine leicht herzustellende und hoch effiziente Tintenpatrone für Drucker zu schaffen. Diese neue Tintenpatrone soll eine zuverlässige und beständige Abgabe der Tinte gewährleisten und die Ausführung des Druckvorgangs steuern.The invention has for its object to provide an easy to manufacture and highly efficient ink cartridge for printers create. This new ink cartridge is designed to ensure a reliable and consistent delivery of ink and control the execution of the printing process.

Die Aufgabe wird durch die im Patentanspruch 1 angegebenen Merkmale vorrichtungsmäßig gelöst.The object is achieved by the device specified in claim 1 features.

Dies wird erfindungsgemäß erreicht durch ein Tinten-Versorgungssystem, das aus einer dünnen und langen Fiber um die Tintenaustrittsöffnung, einen sich von oben nach unten erstreckenden und aus einem elastischen Teil oder Material bestehenden Hebel und einem nach Art eines Labyrinths verlaufenden Kapillarröhrchen besteht.This is achieved according to the invention by an ink supply system consisting of a thin and long fiber around the ink outlet opening, consists of a downwardly extending and consisting of an elastic member or material lever and a labyrinth running capillary tube.

Die dunne und lange Fiber ist von der Spitze bis zum Ende zusammengefügt und erstreckt sich bis zur Tintenaustrittsöffnung, die fest in der Patrone fixiert ist.The thin and long fiber is joined together from tip to tip and extends to the ink orifice fixed firmly in the cartridge.

Das nach Art eines Labyrinths verlaufende Kapillarröhrchen und die zugehörige Anordnung garantiern, dass die Tinte unter normalen bzw. Ausgangsbedingungen nicht zu der dünnen und langen Fiber gelangen kann.The labyrinth-like capillary tube and its arrangement guarantee that under normal conditions, the ink can not reach the thin and long fiber.

Am Ende der dünnen und langen Fiber und des nach Art eines Labyrinths verlaufenden Kapillarröhrchens besteht genügend weiter Raum.There is enough room at the end of the thin and long fiber and the labyrinth-like capillary tube.

Der an der Patrone befestigte Hebel besteht aus einer elastischen Komponente, die von der Spitze bis zum Ende zusammengefügt ist.The lever attached to the cartridge consists of an elastic component joined together from tip to tip.

Der Anfangsabschnitt des nach Art des Labyrinths verlaufenden Kapillarröhrchens ist am untersten Punkt des Tintentanks angeordnet.The initial section of the labyrinth type capillary tube is located at the lowest point of the ink tank.

Durch die dünne und lange Fiber kann die neue Tintenpatrone für eine zuverlässige und gleichmäßige Versorgung mit Tinte sorgen und die Ausführung des Druckvorgangs gleichmäßig steuern.With the thin and long fibers, the new ink cartridge can provide a reliable and consistent supply of ink and control the execution of the printing process evenly.

Dafür umfasst die Tintenpatrone ein Luft-Labyrinth, eine Anordnung, die gegen das Lecken der Tinte absichert, ein nach Art eines Labyrinths verlaufendes Kapillarröhrchens,eine dünne und lange Fiber, einen Tintentank, einen Hebel usw. Bevor die Patrone in den Drucker eingesetzt wird, muss das Luft-Labyrinth geöffnet werden. Die Luft gelangt durch die das Lecken von Tinte verhindernde Anordnung in den Tintentank. Im Tintentank herrscht normaler Luftdruck. Nach dem Einsetzen der Tintenpatrone drückt die dünne, lange Fiber fest gegen die Düse des Druckkopfs. Währenddessen sind die Austrittsöffnung der Patrone und der Druckkopf dicht verschlossen. Wenn der Druckvorgang beginnt, versorgt die dünne und lange Fiber den Druckkopf gleichmäßig mit Tinte. Die Tinte konnte aus dem Tintentank durch das nach Art eines Labyrinths verlaufende Kapillarröhrchen infolge des Drucks, der auch die richtige Menge an Tinte innerhalb der Fiber garantiert, in die Fiber gelangen. Die Luft gelangt durch das Luft-Labyrinth in den Tintentank.For this purpose, the ink cartridge comprises an air labyrinth, an arrangement that protects against the leakage of the ink, a capillary tube running in the manner of a labyrinth, a thin and long fiber, an ink tank, a lever, etc. Before the Cartridge is inserted into the printer, the air labyrinth must be opened. The air enters the ink tank through the ink leakage preventing arrangement. In the ink tank there is normal air pressure. After inserting the ink cartridge, the thin, long fiber presses firmly against the nozzle of the printhead. Meanwhile, the outlet of the cartridge and the print head are sealed. When printing starts, the thin and long fibers will supply the print head with ink evenly. The ink could pass from the ink tank through the labyrinth-like capillary tube into the fiber 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.

Vorteilhaft wird der Druck innerhalb des Tintentanks in einem engen, begrenzten Bereich gehalten, was die Druckreichweite oder Druckausbeute erhöht und die Herstellungskosten reduziert. Außerdem wird der Verbrauch und vor allem der Verlust an Tinte vermindert, was auch dem Umweltschutz zugute kommt. Die neue Tintenpatrone ist gut für die Massenfertigung bei garantierter Qualität geeignet.Advantageously, the pressure within the ink tank is kept in a narrow, limited range, which increases the pressure range or pressure yield and reduces the manufacturing cost. 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.

Wie aus der Zeichnung zu erkennen ist, weist die Tintenpatrone als für die Erfindung wichtige Komponenten einen Hebel 1,einen Tintenbehälter oder Tintentank 2, ein Kapillarröhrchen 3, das nach Art eines Labyrinths verläuft, eine dünne und lange Fiber 4, eine obere Abdeckung 5, eine Austrittsöffnung 6, eine Anordnung 7, die gegen das Lecken der Tinte sichert, ein Luft-Labyrinth 8 und eine Tinten-Füllöffnung 9 in Form einer Düse 9 am Druckkopf auf. Bevor die Tintenpatrone in den Drucker eingesetetzt wird, muß das Luft-Labyrinth 8 geöffnet werden. Die Luft strömt dann in den Tintentank 2, und zwar durch die Anordnung 7, die gegen das Lecken von Tinte absichert, und auch einen normalen Luftdruck im Tintentank 2 aufrechterhält. Nachdem die Tintenpatrone in dem dafür vorgesehenen Halter 10 eines Druckers eingesetzt ist (vergl. Fig. 3a und 3b), druckt die dünne und lange Figer 4 fest gegen die Düse 9 des Druckkopfs. Die Austrittsöffnung 6 der Tintenpatrone und des Druckkopfs ist währenddessen dicht verschlossen. Wenn die Tintenpatrone zu arbeiten beginnt, befördert die dünne und lange Fiber 4 die Tinte gleichmäßig zum Druckkopf. Gleichzeitig befindet sich der Tintentank 2 unter einem leichten Luftdruck, und die Tinte kann zu der dünnen und langen Fiber 4 durch das sich im Verlauf nach Art eines Labyrinths windende Kapillarröhrchen 3 gelangen, welches die richtige Menge an Tinteninhalt in der dünnen und langen Fiber 4 gewährleistet. Die Luft gelangt durch das Luft-Labyrinth 8 in den Tintentank 2.As can be seen from the drawing, the ink cartridge as important components of the invention, a lever 1, an ink tank 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 orifice 6, an arrangement 7, which prevents the leakage of the ink, an 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 placed in the printer, the air maze 8 must be opened. The air then flows into the ink tank 2, through the arrangement 7, which protects against the leakage of ink, and also maintains a normal air pressure in the ink tank 2. After the ink cartridge is inserted in the designated holder 10 of a printer (see FIG. Fig. 3a and 3b ), press the thin and long Figer 4 firmly against the nozzle 9 of the printhead. The outlet opening 6 of the ink cartridge and the print head is sealed during this time. As the ink cartridge begins to work, the thin and long fiber 4 delivers the ink evenly to the printhead. At the same time, the ink tank 2 is under a slight air pressure, and the ink can get to the thin and long fiber 4 through the capillary 3 spiraling in the course 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 in the ink tank. 2
