Abstract

The utility model relates to an environmental protection printer ink box comprising ink box housing and face covering. At least one chamber for ink storage is provided inside the Housing. An ink-supply outlet connected with the printer is arranged in the bottom of the housing. The ink stored in the chamber enters into ink-supply outlet through ink-supply sink. A venthole an ink supplement orifice are arranged on the top of Ink box housing. The Ink supplement orifice is communicated with the chamber for Ink Storage. The venthole is communicated with the air drain arranged in the housing. The air drain communicates with the bottom air inlet of chamber for ink storage. The utility model can maintain constant ink pressure in ink outlet with the fluid pressure principle, thereby the printing quality is guaranteed.

Description

The environmental protection ink-cases of printers

Technical field

The utility model relates to a kind of ink-jet printer consumptive material, and especially a kind of fluid pressure principle adjustment print cartridge that utilizes goes out China ink, and can add the reusable ink-cases of printers of ink.

Background technology

Inkjet printing is a kind of contactless digital printed technology, and this printing technique has that print speed is fast, flexible operation, noise is low and the advantages such as graph image quality height of output, so is widely used.

The used print cartridge of existing ink-jet printer is many to be Chu Moti with the sponge, and there is following shortcoming in this print cartridge:

1. it is few to deposit the China ink amount, because sponge occupies certain space, less relatively with the ink that the print cartridge of volume is stored;

2. the ink utilization rate is low, because the suction-operated of sponge always has a certain amount of ink to use in the print cartridge;

3. easily produce print defect, because sponge is a porous structure, air is adsorbed in the space of sponge easily, become bubble again and flow into shower nozzle together with ink, cause the printing dotted line, moreover ink contacts with the long-time large tracts of land of sponge, the color of ink and chemical property can change, and As time goes on and to some extent the color that prints can change;

4. be unfavorable for regeneration, the print cartridge that uses, remaining in the sponge have bubble and an ink, and the printing effect after the regeneration is had a greatly reduced quality;

5. the pollution to environment is big, because the printing effect of regeneration print cartridge is undesirable, therefore the print cartridge that uses mostly is dropped, and remaining ink can flow into the Nature, causes environmental pollution.

For above-mentioned reasons, occurred in the market a kind ofly substituting the print cartridge of sponge with the threshold pressure valve, the cardinal principle of this print cartridge is a weight of utilizing the pressure of threshold valve to come the balance ink, to keep the normal ink pressure of printing ink mouth.This print cartridge than the progress of original band sponge cartridge some, but the defective that can't overcome below still existing:

1. the threshold pressure of threshold valve is fixed, and the ink in the print cartridge can reduce along with the increase of printing amount, and the ink pressure of printing ink mouth can fluctuate with printing amount, influences print quality;

2. owing to the restriction of production technology, during batch process, the threshold pressure of each threshold pressure valve can be variant, and the print cartridge quality can not get guaranteeing;

3. production technology is comparatively complicated, and production cost is higher.

Summary of the invention

The purpose of this utility model is to can not get guaranteeing, easily pollute and deficiency such as complex manufacturing at price height, print quality that existing print cartridge exists, a kind of fluid pressure principle of utilizing is provided, make the inner air negative pressure that forms naturally of print cartridge come balance ink weight, and reproducible environmental protection ink-cases of printers.

Technical solution of the present utility model is: a kind of environmental protection ink-cases of printers, comprise cartridge case and cover, enclosure interior is provided with the chamber of at least one storage ink, the ink supply port that the lower part of frame setting is connected with printer, the ink of storage enters ink supply port by ink feed slot in the chamber, cartridge case top is provided with a passage and an ink adds the hole, ink adds the hole and is connected with the chamber of storage ink, the passage air flue interior with being arranged on housing is connected, and this air flue communicates with the air admission hole of the cavity bottom of storage ink.

Described air flue is made of the air channel connection that cavity above the storage ink chamber and housing sidewall have.

The beneficial effects of the utility model are: at first, by being arranged on the passage on the cartridge case and the air flue of enclosure interior, utilize fluid mechanics principle, make the self-adjustable atmosphere negative pressure of the inner formation of print cartridge come balance ink weight, it is stable that the printing ink mouth gets ink pressure, guaranteed the quality of printing; Secondly, need not to be provided with sponge or threshold pressure valve in the print cartridge, so the ink storage quantity increase, manufacturing process is simple; Once more, utilize ink to add the regeneration under the prerequisite that does not influence print quality of Kong Keling print cartridge.

The specific embodiment

As Fig. 1 to specific embodiment of the utility model shown in Figure 5, a kind of environmental protection ink-cases of printers, comprise cartridge case 1 and cover 2, housing 1 inside is provided with the chamber 11 of at least one storage ink, the bottom of housing 1 is provided with the ink supply port 12 that is connected with printer, the ink of storage enters ink supply port 12 by ink feed slot 16 in the chamber 11, cartridge case top is provided with a passage 13 and an ink adds hole 14, ink adds hole 14 and is connected with the chamber 11 of storage ink, passage 13 air flue interior with being arranged on housing is connected, and this air flue communicates with the air admission hole 15 of chamber 11 bottoms of storage ink.Air flue is made of air channel 18 connections that cavity 17 above the storage ink chamber and housing 1 sidewall have, and cavity connects passage 13, and air channel connects air admission hole 15.Ink supply port 12 places of housing 1 are equipped with sealing ring 4, sealing nail 5 and Packing spring 6, and filter screen 7 is installed on the path of ink.

As shown in Figure 6, during use, at first open the passage 13 on the cartridge case, and guarantee the airway unobstructed in the housing, the printer of then print cartridge being packed into, the ink supply pin of printer passes sealing ring 4, backs down needle seal 5, and print cartridge begins to be printer ink-providing.When the ink in the print cartridge just forms a vacuum area in the chamber top when water level reduces along with use, at this moment, because extraneous air pressure is greater than storage film chamber interior air pressure, so air constantly enters, and forms stable ink pressure at inkjet mouth.After ink used, the user opened the sealing-plug 3 that ink adds the hole, adds suitable ink, again sealing-plug 3 is installed just and can reuse subsequently.

Claims
