Definitions

  • the invention relates to a new type of print cartridge.
  • the well-known print cartridges realize the printout through a certain structure inside the cartridge. This is done by compressing a porous element within the cartridge, causing the ink to leak.
  • the known print cartridges have the following disadvantages:
  • the porous element occupies part of the ink tank, so that the available ink content is reduced.
  • the suction property of the porous element wastes ink.
  • the effect of the pressure regulator only partially regulates the ink level.
  • only the negative pressure inside the ink tank cannot prevent the ink from leaking.
  • the object of the invention is therefore to provide a print cartridge in which the usability of the ink used is improved.
  • the aim of the new print cartridge is also to create a print cartridge that supplies the entire ink tank with negative pressure, so that the printing process can be better controlled. Not only due to the negative pressure inside the ink tank, but also with mechanical force through the internal structure, the ink leakage is completely prevented when the cartridge is removed from the printer.
  • the print cartridge includes an ink tank, a pressure regulator, a seal ring, a seal ball, and a spring.
  • the pressure regulator is in the ink tank. It consists of a front and a rear valve part, a valve film, a cover and a spring.
  • the valve film is located between the front and rear valve parts, which are close together.
  • the spring is located between the film and the front valve part.
  • a gutter is provided on the rear valve part.
  • the pressure regulator is attached to the lid of the ink tank. Another hole in the lid is connected to the convex opening in the rear valve and thus to air.
  • sealing ring with a sealing ball around the ink supply opening.
  • the sealing ball is pressed into the hole inside the sealing ring by a spring.
  • the entire ink space is under negative pressure.
  • valve film on the pressure regulator has a relatively large area, the vacuum can be checked continuously. This enables a continuous, even flow of ink from the printhead.
  • the ink receiving space is enlarged and ink waste due to the suction effect is avoided.
  • the hole in the sealing ring is completely sealed, so that leakage of the ink can be 100% excluded when the cartridge is removed from the printer.
  • Figure 1 shows the structure of a print cartridge according to the preferred embodiment.
  • Fig. 2 is a view of the pressure regulator of the print cartridge according to the preferred embodiment in a sectional view along the section line labeled A in Fig. 1 and
  • Fig. 3 shows the full view of the print cartridge according to the preferred embodiment in a partially disassembled representation.
  • the print cartridge of the preferred embodiment consists of an ink tank 4, a pressure regulator, a sealing ring 1, a sealing ball 2 and a spring 3.
  • the pressure regulator is located in the ink tank 4. It consists of a front Valve part 5 and a rear valve part 8, a valve film 7, a cover 9 and a spring 3 '.
  • the valve film 7 is located between the front valve part 5 and the rear valve part 8, which are close to each other.
  • the spring 3 ' is located between the valve film 7 and the front valve part 5.
  • a channel (air channel) 12 is provided on the rear valve part 8 , in the middle of the groove 12 there is a concave opening 14.
  • Another opening is in the rear valve, but it is convex.
  • This convex hole is now pressed into the concave opening by a spring.
  • the pressure regulator is attached to the lid of the ink tank.
  • Another opening is drilled in the rear valve, but this is convex.
  • This convex hole is now pressed into the concave opening by a spring.
  • the pressure regulator is attached to the lid of the ink tank.
  • Another hole in the lid is connected to the convex opening in the rear valve.
  • the medium with which the pressure regulator controls the pressure is the air.
  • a valve film opening 15 is located in the area of the rear valve part 8 in the valve film 7, the valve film opening 15 is convex.
  • the valve film opening 15 is pressed into the concave opening 14 by the spring 3 '.
  • the pressure regulator is attached to the lid 9 of the ink tank 4.
  • the valve film opening 15 can be formed by drilling.
  • the medium with which the pressure regulator controls the pressure is air.
  • the round outlet knob on the print head fits into the sealing ring 1.
  • the print head is supported upwards so that the ink can flow through the sealing ring 1 to the printhead.
  • the pressure in the ink tank 4 becomes smaller due to the ink leakage.
  • the valve film 7 on the rear valve part 8 is pulled to the front valve part 5 by the force of the pressure difference.
  • the spring 3 'on the pressure regulator is compressed.
  • the valve film opening in the middle of the valve film 7 is pulled away from the rear valve part 8 so that it comes into contact with air.
  • the valve film 7 is pressed again by the elasticity of the compressed spring 3 ′ towards the rear valve part 8, so that the valve film opening 15 in the valve film 7 is pressed again into the concave opening 14 on the rear valve part 8.
  • the ink tank 4 is again in the sealed state. With the new printing process, the pressure in the ink tank 4 drops again, so that the distance between the rear valve part 8 and the valve film 7 increases.
  • the ventilation hole 11 can be closed with a closure, which is preferably designed as a closure plug for reclosing the ventilation hole 11. This additionally prevents ink from leaking out of the print cartridge, for example during storage or transportation of the print cartridge.
  • the closure can be secured with a sealing film, which is attached to the cover 9 of the print cartridge, preferably by gluing, over the closure plug. As a result, the plug can only be removed after the sealing film has been removed.
  • the sealing ball 2 seals the hole (ink opening 10) with the sealing ring 1 thanks to the force of the spring 3. This force and the negative pressure in the ink tank 4 prevent leakage of the ink.
  • the ink opening 11 can be closed with a further sealing film in order to additionally close the print cartridge during storage or transport, so that in particular dirt cannot penetrate into the ink opening 11.
  • the two sealing foils also make it easy to see that the print cartridge is in an unused state.
  • a print cartridge that consists of an ink tank, a pressure regulator, a sealing ring, a sealing ball and a spring.
  • the pressure regulator is located in the ink tank. It consists of a front and a rear valve part, a valve film, a cover and a spring.
  • the valve film is located between the front and rear valves, which are close together.
  • a gutter is provided on the rear valve part.
  • the pressure regulator is attached to the lid of the ink tank. Another hole in the cover is connected to the convex opening in the rear valve part and thus to air.
  • the print cartridge can also have the property that a rubber sealing ring is inserted in the ink supply opening and that there is a sealing ball inside the sealing ring, which is pressed into the sealing ring by a spring.
  • the print cartridge can also have the property that all openings come into contact with air.
  • the spring 3 ' can be biased to a predetermined spring force in the unactuated state of the pressure regulator.

Abstract

La présente invention concerne une cartouche d'impression comprenant un réservoir d'encre (4) et un régulateur d'impression disposé dans le réservoir d'encre (4). Selon l'invention, le régulateur d'impression présente une partie de clapet avant (5), une partie de clapet arrière (8), un film de clapet (7) et un ressort (3'). Le film de clapet (7) se trouve entre la partie de clapet avant (5) et la partie de clapet arrière (8) et le ressort (3') se trouve entre le film de clapet (7) et la partie de clapet avant (5). De plus, contre la partie de clapet arrière (8) est formé un sillon (12) dans lequel se trouve une ouverture (14), et contre le film de clapet (7) est formée une ouverture de film de clapet (15). Le ressort (3') agit sur l'ouverture de film de clapet (15) pour la faire appuyer dans l'ouverture (14) du sillon (12), le ressort (3') connectant l'ouverture de film de clapet (15) au sillon (12), par l'intermédiaire de l'ouverture (14), lorsque celles-ci prennent appui l'une contre l'autre.
