Abstract

The specialty of an ink box is that the ink box mainly comprises an ink stored chamber, a negative-pressure ink supply chamber in the ink stored chamber and a valve of the ink outlet of the negative-pressure ink supply chamber. An ink absorption groove is positioned between the negative-pressure ink supply chamber and the ink stored chamber, a gas guiding mechanism arranged in the ink stored chamber comprises a gas guiding tube articulated with the inner chamber of the ink stored chamber with the external world and a valve connected with the end of the gas guiding tube. The ink stored box is provided with an ink added port which is provided with a plug. Compared with the prior art, the utility model has the advantages of a large ink storage capacity, availability of repeated use, a good printing quality, easy recovery and less pollution to the environment after the ink box is discarded.

Description

Print cartridge

Technical field:

The utility model relates to the parts on a kind of ink-jet printer, particularly print cartridge.

Background technology:

Ink-jet printer cartridge in the market mainly is divided into the band printhead and is not with printhead two classes, wherein not with the print cartridge of printhead such as the print cartridge of EPSON, the ink carrier of its print cartridge is the foaming sponge, sponge places in the print cartridge and utilizes the concaveconvex structure of cartridge case itself to come compressed sponge, make the density of sponge at print cartridge ink supply port place want big than the density of the sponge at other position, that is the capillary in the print cartridge ink supply port place sponge is thin than the capillary of the sponge at other position, under the effect of surface tension of liquid, liquid in the capillary have a kind of from than the coarse wool tubule to the trend that flows than the fine, soft fur tubule, promptly exist a kind ofly to flow to the pressure of tubule, thereby guaranteed that print cartridge is evenly to printhead supply ink from extra heavy pipe.Though this kind print cartridge is simple in structure, reliability is high, but because sponge itself will take certain space, so just reduced the capacity of print cartridge storage ink, when especially after ink uses up, adding ink again, cause the printing broken string because have air in the sponge, and, after print cartridge is discarded, the sponge that has absorbed ink is contaminated environment not only, simultaneously, has also increased the recovery difficult of useless print cartridge.

Summary of the invention:

Goal of the invention of the present utility model be to provide a kind of storage ink capacity big, can use repeatedly, print quality is good, print cartridge reclaims easily and do not pollute the environment after discarded print cartridge.

The utility model is to realize like this, mainly constitute by ink storage chamber, the negative pressure ink supply chamber that is positioned at ink storage chamber, the valve that is positioned at the ink outlet of negative pressure ink supply chamber, be provided with the blotting groove between ink storage chamber and negative pressure ink supply chamber, in ink storage chamber, be provided with air guide mechanism, air guide mechanism is made of the valve that can be communicated with ink storage chamber inner chamber and extraneous wireway, be connected the wireway end, on the storage print cartridge, be provided with ink and add mouth, add mouth and be provided with stopper.During work, print cartridge is contained on the printer, and the ink outlet of print cartridge is docked with the printhead of printer, and printhead is opened the valve of print cartridge ink outlet, simultaneously, with valve open on the wireway, like this, outside air just can enter in the print cartridge by wireway, guarantee the stable gas pressure in the print cartridge, make print cartridge swimmingly to printhead supply ink, the ink in the print cartridge enters the negative pressure ink supply chamber by ink storage chamber by the blotting groove, is fed on the printhead by the valve of opening again.

Here, in order to control the stability and the continuity of ink of supply printhead, the negative pressure ink supply chamber by ink chamber, be enclosed within valve in the ink chamber, be positioned at the spring of valve between bottom ink chamber and constitute, ink chamber is provided with ink inlet and outlet, outlet communicates with valve, and import communicates with the blotting groove.During work, after the part ink in the space that valve and ink chamber surround is printed head and consumes, the minimizing of the ink in the space that valve surrounds because of valve and ink chamber is inwardly shunk, but under the effect of spring, outside again distending, thereby draw to replenish ink by the blotting groove from ink storage chamber, thus guarantee print cartridge continuously, stably to printhead supply ink.

Here, the valve that is positioned at the ink outlet of negative pressure ink supply chamber can be a check valve, also can be a kapok core.

Check valve is made of the valve pocket that communicates with ink chamber, sealing ring, the spool that has block, spring, sealing ring is positioned at the exit of valve pocket, the block of spool is covered with sealing ring, and in the hole between spool insertion valve pocket and ink chamber, spring is positioned between the block of valve pocket and spool.During work, when print cartridge did not use, sealing ring was stamped outward and seals film, and the block on the spool is covered with sealing ring under the effect of spring, ink can not be flowed out; When print cartridge was contained on the printer, printhead made block leave sealing ring spool jack-up, and like this, the ink in the ink chamber just can enter on the printhead.

In order to make spool freely up and down, simultaneously, when print cartridge does not use, ink is enclosed in the ink chamber, be provided with piston at the other end of spool, be provided with the screens mouth in the hole between valve pocket and ink chamber.Like this, piston had both played the effect of guiding up and down, and simultaneously, when moving down under the effect of spool at spring, piston can not flow out ink the sealing of screens mouth again in ink chamber.

The clarity of the ink in order to guarantee supply on the printhead is provided with the ink filter device in the exit of ink chamber, Cai so that will deliver on the printhead by outlet, valve behind the ink filter.

In order to be contained on the printhead at print cartridge, the valve that is connected the wireway end is opened automatically, and valve is provided with the control link that has piston, is provided with compression spring above the piston.Like this, when print cartridge was contained on the printhead, the printhead base just can make valve open by control link with piston jack-up.

The utility model compared with the prior art, owing to adopted volume little, the negative pressure ink supply chamber that can not take the ink storage chamber space has in a large number substituted sponge, can be when not recharging ink, the air that exists in the sponge causes prints broken string, therefore, have the storage ink capacity big, can use repeatedly, print quality is good, print cartridge reclaims easily and do not pollute the environment after discarded advantage.
