Abstract

The present invention relates to an ink cartridge, and almost the whole space can be used for storing ink. The part of the ink cartridge mainly used for storing ink is an inverted open container with an inverted opening, and the container with an inverted opening is inserted in another open container; foamed plastics can be or does not need to be arranged between the two open containers. A piece 1 can be provided with a printing head or not. A transparent casing is convenient for a person to observe the consumption condition of ink and refill ink. In the process of printing, the ink supply pressure of the printing head is maintained all the time, which provides a condition for the generation of a stable and consistent printing effect. The present invention has the advantages of simple manufacturing technology, material saving, convenient use, etc.

Description

Ink cartridge

Ink cartridge of the present invention is a kind of improvement of ink-jet recording apparatus ink-jet part ink cartridge.

As everyone knows, as the means at the enterprising line item of recording materials, ink-jet recording apparatus has been widely used in printer, printing machine, plotter, facsimile machine, duplicator, various devices such as air brushing machine.

The Inkjet Cartridge of ink-jet recording apparatus is made up of the ink cartridge of printhead and storage ink.What Inkjet Cartridge was general divides three types, and a kind of is that printhead and ink cartridge connect, i.e. " integral type "; Another kind of for both separate, the latter can disassemble, and changes, i.e. " boxlike more than "; Also having a kind of is exactly that printhead is fixed on the body, and ink cartridge can be changed, i.e. " permanent China ink head ".The version of the ink cartridge of which kind of its storage ink of type no matter, nothing more than being: a kind of is to be full of in the ink cartridge to absorb the ink material, as foamed plastics etc.; A kind of be its space only about half of be to absorb the ink material; Also having a kind of is that almost whole space all is used for the splendid attire ink.In in the end a kind of form, be typically structures such as artificial lung is arranged in the print cartridge, though under identical size; it can the more ink of splendid attire, but its complex structure be the more important thing is to be difficult to heavy ink injection; to make full use of the life-span of nozzle, be unfavorable for more and more serious environmental protection problem.

The Inkjet Cartridge of existing ink-jet recording apparatus seldom has ink consumption deixis, so that works need start anew because of ink exhausts before being about to finish.Cause manpower, material resources and waste of time.

An object of the present invention is to provide an improved big capacity ink cartridge.It not only almost makes whole print cartridge space can be used for liquid storage, and structure and manufacturing process are all simple.Can enhance productivity and reduce cost.

Another object of the present invention provides an ink cartridge.It can observe the ink consumption situation.

A further object of the invention provides the ink cartridge of a convenient heavy ink injection.Can be when heavily not annotating, air is discharged from foamed plastics and is produced air sinuses, and the phenomenon that causes spray not go out ink takes place.

The present invention has a purpose to provide an ink cartridge again.In print procedure, the ink supply pressure of keeping printhead all the time is constant, for the printing effect that produces stable and consistent provides condition.

Basic structure of the present invention is the modification of one " draining water gathering of gas law " device.As shown in Figure 1: part 1 is an open containers, ink supply port 4 is arranged at the bottom, be used for partly linking to each other with the not shown printhead of ink-jet recording apparatus, part 2 is a bottom open containers, among the insert 1, between part 2 lower ends and part 1 bottom, can adopt labyrinth sealing or filling to absorb the ink material, for example, foamed plastics 3 prevents ink leakage.Part 1, part 2 and part 3 communicate with atmosphere by the gap, form air duct.This gap size generally is not more than half of arbitrary container maximum straight-line dimension.

Adopt transparent housing in order that be convenient to observe the ink consumption situation and heavy ink injection.

For the needs of production technology, part 1 and part 2 also can be made of one formula.

Ink cartridge course of work principle is as follows: be reduced to part 2 openings when following when ink that nozzle ejection goes out makes ink level in the part 1, air enters the bottom of part 2, its liquid level descends, ink 5 reduces the consumption with ink in the refilling member 1, liquid level in part 1 rises, and seals again till part 2 openings.Go round and begin again, till the ink 5 in part 2 exhausts.

One of feature of the present invention is because the ink 5 of liquid level in part 2 in the part 1 remains before using up constant, so, the ink supply pressure that it can keep ink gun all the time is constant, thereby for obtaining the consistent all the time ink-jet ink-droplet of size, the printing effect that produces stable and consistent provides condition.

With reference to the accompanying drawings, most preferred embodiment of the present invention is described.

Fig. 1 is a basic structure schematic diagram of the present invention.

Fig. 2 is the generalized section of the separate type print cartridge of one embodiment of the invention.

In this example, part 1 is an open containers, and ink supply port 4 is arranged at the bottom, is used for partly linking to each other with printhead, part 2 is a bottom open containers, among the insert 1, places absorption ink material between part 2 lower ends and part 1 bottom, for example, foamed plastics 3 prevents ink leakage.Part 1, part 2 and part 3 communicate with atmosphere by the gap, form air duct.Guaranteeing that it is little to try one's best in the gap, so that improve anti-leakage ability to greatest extent under the unimpeded situation of air.The while confined space filling ink of utilizing as much as possible.Filling absorbent material between part 1 bottom and part 2 openings, as foamed plastics, it both can block the leakage of ink supply port 4, has also increased ink gun and prevent the leakage ability when being inverted.

New clothes or heavy refilling box are full of ink in part 2 and the foamed plastics 3.

The invention has been described with reference to embodiment above, but the present invention can have many modification, all among this scope.
