Description

The ink cartridge that it is easy to fill ink}

The present invention relates to an ink cartridge which is easily filled with ink, and more particularly, forms a main body of the ink cartridge as a transparent body, and constitutes a cap for opening and closing the through hole and the through hole on either side of the main body. By providing a separation membrane having at least one discharge hole formed at a height, a sponge is provided below the separation membrane, and the ink is stored above, so that the state of filling of the ink can always be visualized, so that the filling of the ink is performed efficiently. The present invention relates to an ink cartridge that is easily filled with ink, which prevents damage to a nozzle and enhances product competitiveness to enable self filling.

Generally, a printer is used to output a file (document, picture, etc.) created using a computer. The printer is classified into a dot method using a ribbon, a laser method using a toner, and an ink method using ink.

The dot printer has the advantage of low cost, but excessive noise is generated, and the laser printer has an excessive purchase cost and maintenance cost (replacement cost of the toner and developer). Ink printers were preferred for general business use.

Such an ink printer has a main body configured to have an access assembly configured to discharge paper and finished printed paper on one side, and a guide rail to spray ink while being reciprocated in a transverse direction of the paper provided inside the main body and inserted into the main body. It consists of an ink cartridge reciprocating and filled with ink therein.

In addition, the ink cartridge is configured to be detachable when replacing or filling the ink.

However, in the early days when the ink-based printer was popularized, no means for filling ink into the ink cartridge was invented, so that the number of recyclable cartridges was limited to one, and the maintenance cost of the ink-based printer was excessive. Of course, there was a problem that a large amount of industrial waste occurs.

Therefore, various types of filling tools are being used to develop a technology that allows a user to easily fill a cartridge that is depleted of ink, and the initially developed filling tool is a syringe type, which allows a user to press-fit ink contained in an ink bottle. However, such a syringe-type filling tool was cumbersome because the user has to apply pressure.

As described above, when filling by using a syringe, there is a problem in that the pressure inside the cartridge is increased as the ink is filled and the ink is leaked to the outside.

Due to these problems, in recent years, the ink cartridges go to a specialized charging station equipped with a dedicated ink charger, and thus, there is a problem that the time wasted and the ink charging costs are high with the inconvenience of moving to a specialized charging station.

In addition, the main body of the ink cartridge is opaque, so that the amount of ink can not be visually confirmed, it was limited to efficient ink charging as the time of use or the printing time to determine the charging time is determined.

In addition, when the state in which the ink charge amount is consumed in the ink cartridge is maintained for a long time, there is a problem that there is a limit of recycling that the ink is solidified in the nozzle of the ink cartridge and cannot be reused.

In particular, the ink cartridge is a sealed shape that does not have a separate through-hole and maintains a constant pressure inside the state at all times, thereby preventing smooth filling by internal pressure during ink filling, as well as the nozzle as described above. There was a problem causing the problem that the ink hardens.

The present invention proposes to solve the above problems, an object of the present invention is to form a main body of the ink cartridge with a transparent body and to form a cap for opening and closing the through and through holes on either side of the main body and the inside of the main body There is provided a separation membrane formed with at least one discharge hole at a certain height, and a sponge is provided below the separation membrane and the ink is stored above, so that the filling state of the ink can be made visually at all times. The present invention provides an ink cartridge that is easily filled with ink, which enhances the product competitiveness of preventing nozzle damage and allowing self filling.
