Description

Ink cartridge refilling ink injector {Ink injector refilling ink cartridge}

The present invention relates to a refilling ink injector for refilling ink inside ink cartridges used in various printers. In particular, a top of a cylindrical body filled with a refilling ink is coupled to an opening and closing stopper, and a lower portion of the cylindrical body By forming the outlet opening and closing by the finish opening, not only the ink refilling is easier, but also the handling and storage of the injector is easy, and in particular, the ink inside the container is gradually absorbed and filled by the sponge inside the cartridge by the natural discharge method. It relates to an ink cartridge refilling ink injector that can prevent the print quality degradation by the.

Types of printers include dot printers, inkjet printers, laser printers, and the like. The inkjet printers described above have reliable printing quality compared to a relatively low price, and thus are used in general offices and homes.

As the ink cartridge used in the inkjet printer, a thermal type cartridge is used. The thermal type cartridge has a polyurethane sponge inserted therein according to the internal configuration of the cartridge so that the ink absorbed by the sponge is sprayed outside. Sponge type to be gradually discharged through, and the pressure-controlled air bag is inserted into the automatic pressure control to maintain a constant discharge pressure of the ink discharged through the external injection nozzle.

The above-described conventional ink cartridges are made for one-time use, and when the ink inside the cartridge is completely consumed, it is necessary to replace and use the above-mentioned cartridges, thereby causing a high cost economic burden to the user. It is intended to reuse the cartridge by filling a separate refill ink inside the cartridge.

As such a reusing method, that is, a refilling method of ink, a refilling syringe in which ink is injected or a refilling tube in which ink is filled in an elastic container is used.

After the injection needle is coupled to one end of the refill syringe or the refill tube, the piston of the syringe is forcibly pressed or the tube body is pressed to force the ink therein to be injected into the cartridge, thereby completely removing the sponge inside the cartridge. The refill ink is absorbed to allow the cartridge to be reused.

However, the conventional refilling ink container as described above is very sensitive to unexpected impacts or loads, which makes handling and storage difficult.

In particular, since the air layer is formed in the pores of the sponge inside the cartridge after the ink is consumed, when the ink is filled by the instant forced injection method as described above, the air located in the sponge pores is not discharged and is trapped in the pores. The air layer is a cause of lowering print quality while inhibiting a smooth flow of ink.

In addition, instantaneous forced injection method cannot refill the correct amount of ink, so the ink flows through the injection nozzle by injecting an excessive amount of ink, which may cause contamination of other colors of ink, and a sufficient amount of ink If you fill too little ink and cannot refill, there is a need to repeat the refilling process from time to time.

The present invention was conceived to eliminate the problems as described above, and each of the upper and lower ends of the cylindrical transparent container is formed with a protruding opening and closing port, respectively, the opening and the outlet are respectively formed by connecting the stopper and the closing cap, By opening or closing the container inside and the outside by a stopper, by opening and closing the outlet by the closing cap,

Easy to handle and store the ink injector by the cap and the closing cap which are sealed at the top and the bottom, but gradually filled by the natural discharge method, the air of the sponge inside the cartridge is completely discharged and filled, so the ink is discharged smoothly. The purpose of the present invention is to provide an ink injector for refilling ink cartridges which can be improved, and can be prevented from overcharging and uncharging and can be used more conveniently.

When described in more detail by the accompanying drawings the operation and use of the ink injector for refilling the ink cartridge of the present invention as described above as follows.

As shown in the present invention, the ink injector is designed to reuse the refilling ink when the internal ink of the printer ink cartridge is completely consumed.

The refilling ink 30 is filled into the transparent cylindrical body 1.

Since the scale 2 is displayed on the outer surface of the body 1, not only the filling amount of the refilling ink can be checked, but also the remaining amount of the ink can be visually checked, so that the use is more convenient.

On the upper side and the lower side of the body 1 is formed a protruding opening and closing opening 4 and the discharge opening 6, respectively, the interior of the body 1 is sealed or closed by the opening and closing hole 3 of the opening and closing opening (4) The refilling ink 30 inside the body 1 is discharged or blocked to the outside through the discharge hole 6 depending on whether the opening / closing hole 3 is opened or closed.

In addition, a separate stopper 10 is inserted into the front end of the body 1, the stopper 10 is an opening and closing cover formed with a protrusion pin 13 for opening and closing the opening and closing hole (3) ( 11 is formed integrally with the stopper 10 by a separate connection portion 12, the stopper 10 is to serve to prevent the opening and closing cover 11 is separated from the body (1).

In addition, the inclined protrusion wheel 8 of the upper and lower beams is formed on the outer circumferential surface of the front end of the body 1, and the recessed grooves 14 are respectively formed on the inner circumferential surface of the stopper 10 coupled thereto. While the stopper 10 coupled to the tip of (1) can be more easily inserted by the inclined protrusion wheel 8, the stopper 10 after being inserted is the stopper wheel 8 with the stopper 10 ) Is placed in the groove of the groove (14) will have a more firm fixing force.

That is, the stopper 10 coupled to the front end of the body 1 is a protrusion pin 13 protruding to the inner bottom of the opening and closing cover 11 when the opening and closing cover 11 of the upper side is closed to the stopper 10 side. Is inserted into the opening and closing hole (3) of the opening and closing (4) is to seal the inside of the body (1),

Lifting the opening and closing cover 11 to be separated from the stopper 10 allows the protruding pin 13 of the opening and closing cover 11 to be released from the opening and closing hole 3 so that the inside of the body 1 is opened to the outside. will be.

In addition, the inclined settled groove 9 of the upper and lower strait is formed at the tip of the opening and closing hole 3, and a separate inclined reinforcement 15 is formed at the bottom of the protruding pin 13 of the opening and closing cover 11 corresponding thereto. When the protrusion pin 13 is inserted into the opening and closing hole 3, the reinforcing portion 15 of the protrusion pin 13 is tightly inserted into the settling groove 9 of the opening and closing hole 3. Since the fixing force is to improve the watertightness inside the body (1).

In addition, a separate closing cap 20 is inserted at the lower end of the body 1, and a separate insertion groove into which the outlet 6 of the body 1 is inserted at one center of the closing cap 20 is inserted. Since the 22 is formed, the insertion groove 22 of the closing cap 20 is coupled to the discharge hole 6 to prevent the refilling ink 30 filled in the interior of the body 1 from being discharged to the outside. It is possible,

The outer periphery of the outlet (6) of the body (1) is to form a separate guide wheel (7) to protrude so that the closing cap 20 can be more firmly coupled, the closing cap 20 By forming an insertion opening 21 having an insertion groove 22 on one side of the), the insertion opening 21 can be closely inserted into the inside of the guide wheel 7, the closing cap 20 Is tightly inserted into the outlet (6) and the guide wheel (7) of the body (1) is to maintain a watertight while making a firm fixing.

When the refilling ink 30 filled in the interior of the body 1 as described above is to be recharged in a reusable cartridge, as shown in Figure 4 after removing the closing cap 20 of the lower body 1, the outlet A normal injection needle 32 is inserted into (6), and the injection needle 32 is inserted so as to reach the sponge 33 located inside the cartridge main body 31.

In this insertion process, the refilling ink 30 inside the body 1 is in a state where the tip is blocked by the stopper 10 and the protruding pin 13 even though the outlet 6 under the body 1 is open. Since the ink inside is not discharged to the outside by the pressure, easy handling is possible.

After removing the closing cap 20 from the body 1 as described above, the injection needle 32 is inserted into the cartridge body 31 by inserting the injection needle 32 into the discharge hole 6, as shown in FIG. Opening the upper opening and closing cover 11 is the protrusion pin 13 of the opening and closing cover 11 is released from the opening and closing opening (4) will be able to communicate with the inside and the outside of the body (1).

Therefore, since free air can be freely extracted, the non-liquid refilling ink is absorbed while being discharged to the sponge 33 inside the cartridge body 31 through the injection needle 32, and the discharge speed thereof is the injection needle 32. Through the injection speed of the refilling ink 30 inside the body 1 is naturally discharged,

The refilling ink 30 which is gradually injected by the natural discharge method is filled while completely pushing out the air remaining in the sponge 33 inside the cartridge body 31.

In addition, since the discharge is made gradually and gradually, the user can visually estimate the discharge by visual confirmation of the user, so that the ink can be recharged with a relatively accurate amount, and the accurate filling amount deteriorates the print quality that occurs during overcharge or underfill. This can minimize the problem.

In addition, when the recharging of the ink is completed, when the closing cover 11 is closed again to be combined with the stopper 10, the protruding pin 13 of the opening cover 11 is inserted into the opening hole 3 and the outside air. Closely block the flow of and the refill ink 30 inside the body 1 is no longer discharged.

Therefore, when the refilling of the ink is completed, the body 1 is removed from the cartridge body 31, and then the injection needle 32 is removed, and the closing cap which is discharged to the outlet 6 and the guide wheel 7 ( 20) When inserted and stored, the inside of the body 1 is kept in a sealed state with the outside, thereby preventing the deterioration of the ink, and can be used more easily and cleanly when reused.
