Description

Printer's infinite ink supply {INFINITE INK FEEDER FOR PRINTER}

The present invention relates to an infinite ink supply device for a printer that is applied to a printer and enables continuous ink supply and use of the printer only by replenishing ink without replacing an ink cartridge.

Printers commonly used in homes and offices are divided into two types, inkjet and laser printers. In the case of a laser printer, static electricity is generated in the area to be printed by scanning a laser, and the toner powder is adhered to the area to be printed and then melted and printed with high heat. The result of the output is excellent, but the quality of the toner compatible with the laser is high. On the other hand, an inkjet printer is a method of printing by spraying ink, and has advantages of low power consumption, low cost of printing per sheet, and low maintenance cost because compatible ink can be used. Therefore, in many cases, inkjet printers are used when the quality of output results has little to do with or when a large number of outputs are required.

In the case of an inkjet printer, when it is not used for a long time, the nozzle may become clogged, so constant maintenance is required. When an infinite ink supply device is installed to supply a large amount of ink to an inkjet printer, it is common for an ink container in which a large amount of ink is stored to be mounted outside the printer body, so that ink is hardened in the tube during the process of supplying ink from the ink container to the head assembly located inside the printer body. In this case, there is an inconvenience in that the operation of the printer must be stopped and the tube tube itself must be replaced. In addition, when air bubbles are mixed in the tube tube, the printer does not operate or poor quality output comes out, so there is an inconvenience in that all ink present in the tube tube must be removed and ink must be supplied again to remove the air bubbles in the tube tube. In addition, when the elongated tube tube is undesirably folded, ink does not flow in the tube tube and is clogged.

Accordingly, there is a demand for an infinite ink supply device for supplying a large amount of ink to the head assembly more stably by minimizing clogging of the tube tube while using a long tube by applying an infinite ink supply device to supply a large amount of ink to the inkjet printer. In addition, there is a demand for an endless ink supply device capable of easily removing ink even if ink is hardened or bubbles are mixed in the tube.

To this end, a scale may be formed in the water level display unit 700 . On the other hand, in the case of the floating plate 610 (the floating plate and the first magnetic body coupled thereto), it is made of a material that is lighter than the ink material and floats, so that the remaining amount of ink in the ink refill unit 210, which is invisible from the outside (not visible by the light blocking film), can be grasped by the movement or position of the second magnetic body 710.

In addition, it may further include a plurality of floating plate holes 630 formed to penetrate the floating plate 610 in the vertical direction and spaced apart from each other on the floating plate 610 . Accordingly, even if ink is mixed at the top of the floating plate 610, the ink moves in the direction of gravity through the hole 630, so that the remaining amount of ink can be accurately determined. As described above, the ink refilling unit 210 of the present invention may reverse its vertical direction during the process of refilling ink, and in this process, ink may move in the upper direction of the floating plate 610. By forming the hole 630, the ink that has undesirably moved to the upper end of the floating plate 610 can move to the lower direction again. Meanwhile, in order to prevent ink from being hardened in contact with the floating plate 610 without limitation, the floating plate 610 may have a surface treated with a hydrophobic layer.

When unwanted bubbles are mixed in the supply tube, it can be easily removed by the suction device 370. In the conventional case, when air bubbles are mixed, there is a problem in that all ink present in the tube of the supply tube must be removed and ink must be supplied again. However, in the case of the present invention, several section supply tubes are connected by a connecting member 350, the stopper 360 is removed at a position close to the position where the bubble is generated, and the bubble removal part 352 close to the position. By sucking the ink into the suction device 370, the bubble can be easily removed without removing all the ink. Of course, when there is no need to remove air bubbles through the stopper 360, the ink can move smoothly in the supply tube.

On the other hand, the first valve 353 and the second valve 354 include portions cut with a - shape so that ink does not leak through the first valve 353 or the second valve 354 when a certain or more pressure is not applied, and a buffer layer can be formed between the first valve 353 and the second valve 354 so that the bubble removal process proceeds more stably. For this buffer layer, ink may remain in a part of the space between the first valve 353 and the second valve 354 . In addition, by sucking ink in the ink space between the first valve 353 and the second valve 354 through the suction device 370, the ink in the vicinity of the bubble is sucked together, so that the bubble can be stably removed.

Air bubbles mixed in the supply tube 302 are sucked and removed through the teeth 380, ink sucked together during the air bubble suction process is absorbed by the absorbent member 1050, and the air bubbles removal kit 1040 can be removed and replaced.

The bubble removal kit 1040 is formed to be coupled to or separated from the connection pipe 1030, and the used bubble removal kit 1040 can be removed and discarded. In the process of sucking and removing air bubbles, the ink may be unintentionally ejected along with the suction member (for example, the air intake) and contaminated, and the ink may come into contact with the user's skin and become contaminated. In the case of ink used in inkjet printing, it may be difficult to simply wash off with water. Therefore, as in the present invention, ink coming out with bubbles is absorbed through the absorbent member 1050 covering the other end of the connection pipe 1030 in the bubble removal kit 1040, thereby preventing unnecessary contamination by the ink, and the used absorbent member 1050 separates and discards the kitted bubble removal kit 1040, so that the bubble removal process can be performed more cleanly. The absorbent member 1050 may be formed of, for example, a member such as a sponge to absorb air and remove air bubbles while absorbing ink coming out together.

The bypass member 1000 may include a clamp 1010 to prevent ink from being sucked in by being mixed with ink at other positions of the supply tube where bubbles are generated during use. For example, the clamp 1010 pressurizes the front end of the supply tube where bubbles are generated to stop the flow of ink, sucks and removes the ink with bubbles at the rear end, thereby reducing waste of unnecessary ink and performing a process of precisely removing bubbles.
