Definitions

  • the present invention relates, in general, to a suction kit for ink cartridges and, more particularly, to a suction kit for ink cartridges, which is intended to easily expel a predetermined amount of air and ink from an ink cartridge after refilling ink into the ink cartridge.
  • an ink cartridge used in an ink jet printer is constructed so that it is filled with ink and distributes ink through an ink injection nozzle provided at a predetermined position on the outer portion of the ink cartridge.
  • the ink cartridge is replaced with a new one. Even though the whole amount of ink is exhausted under a normal condition, a printer head including the ink injection nozzle maintains its performance.
  • the ink cartridge may be used ten or more times by refilling ink into the ink cartridge. Therefore, many users prefer to reuse the used ink cartridge by refilling ink into the ink cartridge rather than replace the expensive ink cartridge with a new one.
  • ink After ink is refilled into the ink cartridge, it is required to expel a predetermined amount of air and ink from the ink cartridge.
  • the reasons for conducting the expelling operation vary slightly according to the kind of ink cartridge. That is, a pack- type ink cartridge is constructed so that its interior always maintains negative pressure. However, during an ink refilling process, external air flows into the ink cartridge, so internal pressure may become unbalanced. Thus, a predetermined amount of air must be expelled from the cartridge so as to maintain a preset negative pressure.
  • a sponge- type ink cartridge is provided with an additional passage through which external air circulates. Thus, even though external air is fed into the ink cartridge during an ink refilling process, it is not necessary to consider the balance of internal pressure.
  • impurities such as fine dust or air drops
  • print quality is deteriorated.
  • the impurities must be removed by expelling a predetermined amount of ink through the injection nozzle.
  • FIG. 1 An conventional suction kit are shown in FIG. 1.
  • the conventional suction kit 3 has a structure similar to a syringe used in hospitals.
  • the suction kit includes a cylindrical body 4 having at a predetermined position thereof a suction port.
  • a piston 5 is inserted into the body 4, and a packing member 7 is attached to an end of the piston 5.
  • An elastic pad 6 is attached around the suction port with which the suction kit 3 and an ink injection nozzle 2 of the ink cartridge 1 are in close contact, thus preventing air from leaking out.
  • an additional case 8 may be used, as shown in FIG. 2.
  • the ink injection nozzle 2 comes into close contact with the elastic pad 6 attached to the front of the case 8, and the ink cartridge 1 can communicate with an exterior through a kit rod mounting part 9, having a passage therein. Thereafter, when the suction kit 3 is inserted into the kit rod mounting part 9 and the piston 5 is moved back, air and ink are easily expelled from the ink cartridge 1 by negative pressure produced in the body 4.
  • the ink cartridge 1 is brought into close contact with the elastic pad 6 merely by mounting the ink cartridge 1 in the case 8.
  • air and ink may be expelled from the ink cartridge 1 only by the force F moving backward the piston 5, without the necessity of applying an additional force to the suction kit 3.
  • the ink cartridge 1 is stably held in the case 8, it is not necessary to worry about whether the ink cartridge 1 will fall down during the expelling operation.
  • such a method is problematic in that several cases 8, as well as the suction kit 3, must be prepared according to the kind and shape of the cartridge, so that high costs are incurred.
  • an object of the present invention is to provide a suction kit for ink cartridges, intended to conveniently expel air and ink from the cartridge merely by pressing the ink cartridge or the suction kit.
  • the present invention provides a suction kit for ink cartridges, including a cylindrical body closed at an end thereof; a slider including a sealing block inserted into the body to maintain airtightness of body, a rod extending from the sealing block, and a suction path which is defined in the rod and extends to an upper end of the rod; an outlet hole which is formed in a lower portion of the rod and can communicates with the suction path; and a pad coupled to the upper end of the rod in such a way that the suction path of the rod can communicate with an injection nozzle of the ink cartridge being brought into close contact with the pad.
  • the body comprises an ink container closed at an end thereof and a rod support boss passing through the closed end of the container. The upper end of the rod is airtightly inserted into rod support boss.
  • the suction kit further comprises a housing cap which is fitted over the ink container to cover the closed end of the ink container and supports the ink cartridge.
  • the housing cap includes a cylindrical cover closed at an end thereof and a rod mounting part formed through the closed end of the cover to support the end of the rod.
  • the pad includes an elastic plate attached to the closed end of the cover, and a suction hole formed on the elastic plate to communicate with the rod mounting part.
  • the present invention provides a suction kit for ink cartridges, which need not prepare various kinds of cases, unlike a prior art, and allows air and ink to be easily expelled from an ink cartridge merely by pressing the suction kit, thus affording a convenient operation.
