Background technology
In recent years, along with computer in the extensive use of every field and the continuous growth of home computer owning amount, the market sales volume of printer is also soaring thereupon.Especially since a large amount of listings of digital camera, entered the digital network New Times, people are the gesture of fast rise to the demand of colour print.No matter be the photo that digital camera is taken, or the exquisite picture of network download, the personalized works of perhaps creating on the computer, people wish indiscriminately ad. as one wishes to print appreciation, collection.Yet because the color laser printer price is higher, color inkjet printer consumptive material costliness causes the ink-jet printer user generally to meet with the embarrassment of " afford printer, use not rise print cartridge ", and the have a great longing for liberty fine ideal printed of people is failed realization all the time.
The invention of ink-jet printer and go into operation similar 10 years, early stage is because print quality and print speed can not be satisfactory, the market mainstream of always failing to become, but recent years, variation took place in situation, because software and hardware technology is increasingly mature, the print quality and the print speed of color inkjet printer significantly improve, not only can satisfy the needs of the various figure message printings of people, also be born need not connect computer just directly plug-in card print the photo-printer having of digital photograph, printing effect can be developed and printed photo with traditional silver halide film and compare favourably.
Compare with color laser printer, color inkjet printer is cheap, simple in structure, but, a crux on the color inkjet printer designing technique, or perhaps the consumptive material strategy of production firm cause the instream factor of color inkjet printer very low, development is gone down like this, along with the reduction of color laser printer production cost, ink-jet printer will withdraw from the arena of history very soon, though this is very wrong concerning it.
As everyone knows, the use cost of color inkjet printer mainly is a consumptive material, and except print media, consumptive material is exactly a record head, and record head comprises ink gun and print cartridge, and print cartridge then is made up of ink tank and printing ink.Early stage ink-jet printer all is ink gun and being made of one of print cartridge, and after the printing ink in the print cartridge used up, whole record head was all discarded.Why so design is in order to guarantee print quality on the one hand, also is that the consumptive material strategy of manufacturer is required on the other hand.Generally meet with users after the embarrassment of " afford horse, can not be equipped with saddle ", some manufacturer has changed strategy, ink gun is made semi-permanent, and the print cartridge independent design is removable, but the use of print cartridge remains disposable, and brings a high price.Got successfully though some user attempts to fill printing ink in the print cartridge that has used up, that is not that ordinary consumer can be grasped.In addition, because the split design has reduced the reliability that fluid connects, having to is wasting a large amount of " preciousness " printing ink in ink gun " cleaning " operation continually, and this split design of result does not reduce user's use cost.
In fact, ink gun is quite durable, the printing ink in short-life just print cartridge.No matter be " thermal " formula or the ink gun of " minute-pressure " formula, under regular service conditions, for the A4 breadth color text of 15% area coverage, an ink gun can be printed 30,000 pages at least, and this is confirmed by the applicant's practice.If in the whole service life of ink gun, only need to replenish printing ink and need not change print cartridge, so, the use cost of ink-jet printer will be reduced to existing cost 1/10th in addition lower, make color laser printer too far behind to catch up.
The automatically supplying ink system design scheme that the present invention proposes, purpose is exactly in order to address the above problem, and objective for implementation can be the ink jet recording device of any brand, any kind, the objective of the invention is need not change by only needing to replenish printing ink that print cartridge realizes.
In disclosed prior art scheme, the patent of invention that has three Chinese utility model patents and a hewlette-packard to have is similar to purpose of the present invention, but there are difference in essence in its technical scheme and the present invention.Its publication number and invention and created name be respectively " CN2355886Y automatically supplying ink in ink jet printer device ", " CN2536401Y automatically supplying ink in ink jet printer device ", " CN2555154Y continuous ink feeding device " and the U.S. " 5966156 in ink-jet strip printer/draught machine the flexible bag holder continuously again the filling ".At this in the lump as quoting material.
The objective for implementation of above-mentioned three Chinese patents only is the ink-jet printer that has the sort of EPSON of ink supply pin on the record head, and behind these three patent workings, the ink supply instability all can not produce a desired effect, thereby not possess practicality.That of hewlette-packard patent need not implement just to know that it does not possess practicality yet, because it is the same with above-mentioned three patents of China, all fails to overcome a technology prejudice.This technology prejudice is exactly black liquid liquid level in the ink feeding system and the horizontal level relation between the nozzle on the ink gun.This technology prejudice is because the natural general knowledge of siphonage and " Water seeks its own level " has limited technical staff's thinking causes.
