Abstract
The present invention relates to an ink supply device, and more particularly, to the ink refill ink supply, etc., and to improve the print quality and ink so that the outside air is introduced when the printer print operation, and the outside air is blocked when the printer is stopped. An ink supply apparatus which can achieve savings.
It is an object of the present invention to provide an ink supply device which not only smoothly supplies external air at the time of printing but also automatically cuts off the supply of external air at the time of printing stop.
In order to achieve the above object, the present invention provides an ink container having one end of the ink discharge pipe 1 penetrated on the upper side thereof and exposed to the outside, and the other end being located on the bottom surface of the inside of the ink container. 3), a lid 4 formed to seal the inlet 2 of the ink container 3 and detachable therebetween, and penetrated through the upper side of the ink container 3 so that one end is exposed to the outside. And the other end is coupled to the inflow pipe 5 located on the bottom side of the inside of the ink container, and the upper portion (exposed portion of the inflow pipe 5) of the inflow pipe 5, so that the negative pressure inside the ink container 3 when printing the printer. When formed, the air is introduced into the ink container (3), characterized in that it consists of a valve means configured to block the inflow of external air while being contracted when the suction pressure is removed when printing stops.
Description
The present invention relates to an ink supply apparatus, and more particularly, to be applied to an endless refill ink supply, etc., and to improve the print quality and ink by allowing the outside air to flow in when the printer is printing and the outside air when the printer is stopped. It relates to an ink supply device which can achieve savings.
In general, the infinite refill ink supply device used in inkjet printers and the like to install a large-capacity ink container on the outside of the printer, by connecting the ink container to the cartridge of the printer so that ink can be supplied to the cartridge to reduce the cost It is made up.
The ink supply device is configured to install four or six ink containers for each color of the ink and to connect the cartridge and the supply pipe of the printer. The ink container is always kept open to allow the outside air to flow. do.
That is, in order to supply ink from the ink container to the cartridge, external air must be supplied to the ink container. For this purpose, the lid of the ink container is always opened.
However, as described above, if the lid of the ink container is left open at all times, ink supply is easily performed at the start of printing, but even when the printing is stopped, ink flows into the cartridge by external air, which causes the ink to flow into the cartridge. There is a problem that oversupply occurs.
That is, even though printing is stopped, a small amount of ink is supplied to the cartridge due to the weight or inertia of the air and ink, which causes excess ink in the cartridge, resulting in deterioration in print quality due to excess ink at the next printing. There is a problem.
Accordingly, an object of the present invention is to solve the above problems, and to provide an ink supply device which not only smoothly supplies external air during printing but also automatically cuts off the supply of external air when printing is stopped. .
In order to achieve the above object, the present invention provides an ink container having one end of the ink discharge pipe penetrated through the upper side thereof and being exposed to the outside, and the other end being located at the bottom of the inside of the ink container, and having an inlet formed thereon. A lid formed to seal the inlet and detachable, an inlet tube penetrating through the upper side of the ink container, one end of which is exposed to the outside and the other end of which is located on the bottom side of the inside of the ink container, The valve means is coupled to the upper part (exposed part) and configured to block the inflow of external air by expanding when negative pressure is formed inside the ink container during printing of the printer, and introducing air into the ink container and contracting when the suction pressure is removed when printing is stopped. Characterized in that the configuration.
As described above, the present invention installs a chamber at an upper end of the ink container so as to be connected to an inlet pipe in an ink supply device applied to an infinite refill ink supply device, and installs a suction pipe formed with a cutout therein, so that the negative pressure according to printer printing inside the ink container is maintained. If this is formed by sucking the outside air and interrupt the outside air when printing is interrupted, there is an advantage that the print quality can be improved.
