Description

A kind of print cartridge

Technical field

The utility model relates to a kind of print cartridge, particularly a kind of sponge-free ink box of ink-jet printer.

Background technology

The print cartridge that is used for ink-jet printer in the market mainly is a sponge cartridge, this class print cartridge is because exist sponge in the print cartridge, itself in print cartridge, occupy than large space, so cause the interior splendid attire ink capacity of box limited, and sponge and ink long-term co-existence meeting rot, and when serious plug nozzle can't be used; In addition, because sponge is a porous mass, print cartridge can and accumulating are had higher requirement, careless slightly will have air to enter sponge, has a strong impact on thereby printing caused; Sponge cartridge also has a significant disadvantages, and the print cartridge ink residual quantity that uses exactly is big, and the ink utilization rate is low, and contaminated environment, not environmental protection.

In addition, existing no sponge print cartridge or the design of employing back pressure, or adopt one-way valve structures.The easy ink leak of no sponge print cartridge of back pressure design, nozzle stops up easily; And adopt the no sponge print cartridge of one-way valve structures when the filling China ink, to be difficult to make ink to arrive ink supply port, cause print defect, and when print cartridge is installed, can damage nozzle and cause a China ink.

So existing technology has the following disadvantages: Rong Moliang is little, residual quantity is big, low, the easy ink leak of ink utilization rate, nozzle stop up easily, not environmental protection.

The utility model content

Technical problem to be solved in the utility model is the deficiency that overcomes on the prior art, provides a kind of and holds that China ink amount is big, residual quantity is little, ink utilization rate height, is difficult for that ink leak, nozzle are difficult for stopping up, the print cartridge of environmental protection.

The technical scheme that the utility model adopted is: the utility model comprises box body, cover, go out device for ink, described cover is provided with gas port, be sealed with the air guide film on the described gas port, describedly go out device for ink and comprise valve body, spool, filter screen, sealing ring, seal film, described valve body and described box body are fixedly connected, described spool is arranged at the chamber internal upper part of described valve body, the sidewall of described spool is provided with several I side openings, the side wall perimeter of described spool is overlapped flexible internal valve film, described internal valve film covers described I side opening, the bottom of described sealing ring and described valve body is fixedly connected, described sealing ring is axially arranged with through hole, described filter screen is connected the described described through hole of membrane closure that seals with described valve body top mouth.

Describedly go out device for ink and also comprise the outer valve film of elasticity, the sidewall of described valve body is provided with several II side openings, and described II side opening is communicated with described box body inner chamber and described body cavity, and described outer valve Membrane cover is in described body wall periphery and cover described II side opening.

The beneficial effects of the utility model are: owing to do not have sponge in the box body described in the utility model, than existing sponge cartridge bigger Rong Mo space is arranged, and the putrefactive phenomenon that does not exist sponge and ink long-term co-existence to occur, not therefore can be and plug nozzle causes print cartridge to use, can not occur also that print cartridge is attracted deposits ink and situation about can not use up, the China ink amount is big, residual quantity is little so the utility model holds, ink utilization rate height, nozzle are difficult for stopping up, helping environmental protection;

Owing to described in the utility modelly go out device for ink and comprise valve body, spool, filter screen, sealing ring, seal film, described valve body and described box body bottom are fixedly connected, described spool is arranged at the chamber internal upper part of described valve body, the sidewall of described spool is provided with several I side openings, the side wall perimeter of described spool is overlapped flexible internal valve film, described internal valve film covers described I side opening, the bottom of described sealing ring and described valve body is fixedly connected, described sealing ring is axially arranged with through hole, described filter screen is connected with described valve body top mouth, the described described through hole of membrane closure that seals, when print cartridge is installed, the through hole of tattooing needle by described sealing ring of getting on the printer nozzle stretches in the described valve body (being ink supply port), when static, because described internal valve film self has elastic force, the pressure that black liquid produces in the print cartridge is offset by the back pressure that described internal valve film produces, so nozzle can ink leak when static; When the outside ink-jet of nozzle, in ink supply port, produce certain negative pressure, under the pressure double action of this negative pressure and black liquid generation itself, the back pressure that described internal valve film produces is not enough to offset, ink replenishing is in ink supply port in the print cartridge, the then described internal valve film of lasting ink-jet continues to open, ink is constantly replenished in the ink supply port, if a certain moment, nozzle stops ink-jet, then the negative pressure in the nozzle disappears, the reinstatement under self resilient force of described internal valve film covers described I side opening, is returned to the inactive state pattern again, any moment, the pressure of China ink liquid top equates all the time with printer working environment pressure, the ink supplied of oriented nozzle, all passed through described strainer filtering, thereby avoid plug nozzle, so the utility model is difficult for ink leak, nozzle is difficult for stopping up;

Owing to described in the utility modelly go out device for ink and also comprise the outer valve film of elasticity, the sidewall of described valve body is provided with several II side openings, described II side opening is communicated with described box body inner chamber and described body cavity, described outer valve Membrane cover is in described body wall periphery and cover described II side opening, gas port from described cover when irritating China ink vacuumizes described box body inside, because described outer valve film is an elastomer, and only to the inner conducting of print cartridge, so this a part of air of ink supply port inside can be taken away, when the vacuum of print cartridge inside reaches requirement, ink poured into described box body, because the unidirectional conduction of described outer valve film, ink can not be back in the ink supply port, and the conducting in ink supply port at this moment of described internal valve film so ink enters ink supply port by it, thereby solves the shortcoming that the ink supply port ink is difficult to arrive; When print cartridge is installed to printer, printer is got tattooing needle and is extend in the ink supply port via described sealing ring, because ink belongs to incompressible fluid, ink pressure in the ink supply port can increase, described outer valve film conducting this moment, described internal valve film ends, ink valve film outside described is extruded ink supply port, the volume of extruding ink is approximately equal to gets the ink volume that tattooing needle arranges, make that the pressure in the ink supply port was released when print cartridge was installed, thereby damage printer head when having avoided the print cartridge installation and drip black defective from nozzle, so be full of ink easily in the utility model ink supply port, can improve print quality, not fragile printer head during the print cartridge installation is difficult for dripping China ink from nozzle.
