Description

Tintenpatrone für Tintenstrahldrucker Ink cartridge for inkjet printers
Beschreibungdescription
Die Erfindung bezieht sich auf eine Tintenpatrone für Tintenstrahldrucker .The invention relates to an ink cartridge for inkjet 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; (Canon hält das Patent) . 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.Two types of ink cartridges for ink jet printers are currently known in the market. Some use a porous substance or fiber bundle, on the one hand to prevent ink leakage and, on the other hand, to achieve a uniform release of the ink; (Canon holds the patent). The others use a one-way valve and a pressure-adjusting arrangement with fiber within the cartridge to control the even delivery of the ink.
Diese Tintenpatronen haben folgende Nachteile: Die poröse Substanz und die Fiber beanspruchen einigen Raum innerhalb des Tintenbehälters, wodurch der Druckertrag gemin- dert 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 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.
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. This new ink cartridge is designed to ensure reliable and consistent dispensing of the ink and to control the execution of the printing process.
Dies wird erfindungsgemäß erreicht durch ein Tinten-Versorgungssystem, das aus einer dünnen und langen Fiber um die Tin- tenaustrittsöffnung, einem sich von oben nach unten erstreckenden und aus einem elastischen Teil oder Material bestehenden Hebel und einem nach Art eines Labyrinths verlaufenden KapiUarrohrchen besteht.According to the invention, this is achieved by means of 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.
Die dünne 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 from the tip to the end and extends to the ink outlet opening, which is firmly fixed in the cartridge.
Das nach Art eines Labyrinths verlaufende KapiUarrohrchen und die zugehörige Anordnung garantieren, dass die Tinte unter normalen bzw. Ausgangsbedingungen nicht zu der dünnen und langen Fiber gelangen kann.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.
Am Ende der dünnen und langen Fiber und des nach Art eines Labyrinths verlaufenden Kapillarröhrchens besteht genügend weiter Raum.At the end of the thin and long fiber and the capillary tube, which runs like a labyrinth, there is enough space.
Der an der Patrone befestigte Hebel besteht aus einer elasti- sehen Komponente, die von der Spitze bis zum Ende zusammengefügt ist.The lever attached to the cartridge consists of an elastic component that is assembled from the tip to the end.
Der Anfangsabschnitt des nach Art eines Labyrinths verlaufenden Kapillarröhrchens ist am untersten Punkt des Tintentanks angeordnet .The initial section of the labyrinthine 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 steu- ern.Thanks to the thin and long fiber, the new ink cartridge can ensure a reliable and even supply of ink and evenly control the execution of the printing process.
Dafür umfasst die Tintenpatrone ein Luft-Labyrinth, eine Anordnung, die gegen das Auslecken der Tinte absichert, ein nach Art eines Labyrinths verlaufendes KapiUarrohrchen, 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 Auslecken 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 Tin- tentank durch das nach Art eines Labyrinths verlaufende Kapil- larröhrchen 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 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. 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.
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 Masseanfertigung bei garantierter Qualität geeignet.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.
