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 decompression ink-supplying mechanism that is positioned at ink storage chamber, the valve that is positioned at the outlet of decompression ink-supplying mechanism ink, 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, the ink outlet of print cartridge is docked with the printhead of printer, 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, guarantees the stable gas pressure in the print cartridge, make print cartridge swimmingly to printhead supply ink, ink in the print cartridge is introduced into the decompression of decompression ink-supplying mechanism, is unlikely to be subjected to the influence of ink level height in the ink storage chamber with the pressure of the ink on the printhead of the printer of guaranteeing supply, and makes ink pressure keep stable low pressure, then, ink is fed on the printhead by the valve of opening again.

Here, the decompression ink-supplying mechanism is made of airtight labyrinth type pipeline, and the import of pipeline is connected with ink storage chamber, and outlet is connected with valve.During work, when with valve that the outlet of decompression ink supply chamber links to each other in ink be printed head and consume after, the ink in the ink storage chamber then carries out additional by mazy pipeline to it again.According to liquid or the gas principle that its pressure can reduce behind the tortuous pipeline of flowing through, ink is flowed through behind the labyrinth type gas relief line, its pressure will greatly be extenuated, thereby the subduction liquid level is to the direct pressure of printhead, and realize the supply and demand formula supply ink of printhead, guaranteed print cartridge continuously, stably to printhead supply ink.

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

Check valve is made of valve pocket, the sealing ring, the spool that has block, the spring that communicate with the ink outlet of decompression ink supply chamber, 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.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, and 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 valve pocket just can enter on the printhead.In order to make spool freely up and down, in the hole of valve pocket and relief chamber outlet, be provided with the screens mouth, play the effect of guiding up and down.The other end at spool is provided with the taper screens, and the effect of taper screens is to prevent that spool from crossing the landing in the hole of screens mouth and getting off.

The clarity of the ink in order to guarantee supply on the printhead is provided with the ink filter device at the relief chamber ink inlet, Cai so that will deliver on the printhead by labyrinth type gas relief line, 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 decompression 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.
