Description
Technical field
The present invention relates to the print cartridge that ink-feeding device, particularly ink-jet printer that ink vapo(u)r recorder uses are used.
Background technology
That Chinese invention patent ublic specification of application CN1252353A discloses is by name " China ink jar, comprise this China ink jar assembly, and use the PRN device of this assembly " innovation and creation, and provided the embodiment of a print cartridge by its Figure of description 5, this print cartridge is a bicavate print cartridge that is divided into by dividing plate, the pore that blotting material, ink supply port is arranged and be communicated with atmosphere in chamber; Another chamber is the liquid storage chamber of base closed, and a channel connection is passed through in two chambeies near the bottom of dividing plate.When blotting material ink absorbed is consumed by printhead, black liquid is supplied with the blotting material through the interface channel in two chambeies in the liquid storage chamber, when the negative pressure when the liquid storage chamber in ink supply process lumen increases gradually, from pore and pass the blotting material air add to the liquid storage chamber through interface channel, negative pressure in the liquid storage chamber, the end is fallen, formation is for the negative pressure of printhead substantial constant, thereby makes the ink that supplies to printhead keep stable.Tp with isosceles triangle shape of 90 ° of drift angles is arranged in the bottom in liquid storage chamber, its electrooptical device in printer constitutes China ink checkout gear to the greatest extent, the detection principle is as follows: when enough inks are arranged in the print cartridge, a waist place of incident light arrival triangle face just folds into ink and is absorbed, thereby photoreceptor can't receive optical signal; When consumption of ink was following to the reflective spot of prism, incident light arrived photoreceptor abreast through triangle two waist place face two secondary reflections, and printer can send China ink signal to the greatest extent after photoreceptor was received optical signal.
It must be noted that, send China ink to the greatest extent during signal at printer, only illustrate in the liquid storage chamber inkless, because the capillarity of blotting material in another chamber, still there is a certain amount of ink, so, after receiving the most signal of China ink, also can proceed a certain amount of printing, this benefit of bringing to printer user is, can arrange printing after this, for example, receive China ink and to the greatest extent generally can continue to print some standards behind the signal and open, when the number of pages of Da Yining is counted above this if desired, should change print cartridge, avoid changing print cartridge midway at multi-page printing.
Summary of the invention
It is well-known that there is the problem of a maximum in the print cartridge of said structure, exactly every print cartridge to contain the China ink amount very low, reason is that the blotting material adopts sponge usually, and sponge has occupied very big volume in the chamber, the volume that is used to contain China ink reduces relatively; Another problem that exists judges that referring to Figure 12 the most operate as normal of China ink is, light path such as the ABCD of light from emission source A to photoreceptor D, the photoreceptor that is positioned at D place receive that sending normal China ink behind the light from the A place uses up signal.But find in the use, under the situation that China ink is arranged, though light folds in the China ink at the first pip B place usually, but sometimes because emission source is not desirable all multifactor influences such as minor deviations that spot light, the carriage return of printer vehicle frame are not in place, print cartridge is installed, when often having occurred in China ink, light is the situation to D place photoreceptor from the 3rd pip E point reflection, thereby causes and send the most rub-out signal of China ink.Therefore, problem to be solved by this invention is a kind of print cartridge structure that can cancel sponge of design, under the prerequisite that guarantees substantially constant negative pressure and ink supply quality, improve the specified content value of every box China ink, and solve under the no sponge situation, send China ink to the greatest extent behind the signal, continue to supply the problem of a certain amount of China ink.Another problem that the present invention need solve is to eliminate and send China ink rub-out signal phenomenon to the greatest extent.
For solving the problems of the technologies described above, scheme of the present invention is still a box body that has black chamber in general, on a face of box body, be provided with the ink supply port of sealing ring, relative another side has a passage that communicates with atmosphere, keep substantially invariable negative pressure in the black chamber in the ink supply process, making, the check valve of a side is set in box body, and the arrival end of check valve is communicated with black chamber, and the port of export is communicated with ink supply port.Be the problem that can continue after solving China ink to the greatest extent signal showing surplus the printing ten, black chamber is divided into main chamber and auxilliary chamber from principle, China ink is set near the interconnecting part in main chamber and auxilliary chamber detects prism to the greatest extent, and auxilliary chamber is included in the main chamber, auxilliary chamber is communicated with the arrival end of unidirectional valve pocket.The ink supply course of work of print cartridge is as follows, unidirectional opening of valves under the effect of printer port of printer suction, Mo Jingfa, ink supply port in the China ink chamber are confessed, China ink in this process in the auxilliary chamber does not consume, when the China ink except that auxilliary chamber in the main chamber exhausts, when having only the full China ink in auxilliary chamber in other words, China ink checkout gear to the greatest extent sends China ink signal to the greatest extent, after this, can continue ink supply by auxilliary chamber and print a certain amount of printed matter.
For solving the to the greatest extent problem of rub-out signal of China ink, the present invention is in the box body outside at place, prism place, more particularly, is that the 3rd pip E place is provided with a China ink and detects the prism dividing plate to the greatest extent.
By above technical solution as seen, when the China ink in the ink supply port is exhausted when a certain amount of, the negative pressure of the check valve port of export is lower than the arrival end negative pressure, the check valve conducting, the China ink in the black chamber flows to ink supply port by check valve, when the negative pressure at check valve two ends tends to balance, check valve is closed automatically, the increase of China ink chamber outflow China ink back negative pressure is then offset by the atmosphere that plasmas channel is introduced, thereby has kept substantially invariable negative pressure in the black chamber, has guaranteed to give the normal ink supply of printer.Owing to saved sponge, increased the volume in black chamber relatively, improved print cartridge storage China ink amount about 30～60% greatly.Adopted the design in main and auxiliary two black chambeies, when the China ink in the main chamber is used surplus and is the auxilliary chamber amount of having stipulated, China ink checkout gear to the greatest extent will send China ink signal to the greatest extent, and at this moment, whether the user can utilize in the auxilliary chamber China ink to print according to actual printing demand decision again.
Owing to set up the China ink of splitting shape at the 3rd pip place and detect the prism dividing plate to the greatest extent, the light source that broken is through the light path of this point reflection to photoreceptor, thereby effectively avoided because the 3rd pip causes the China ink problem of rub-out signal to the greatest extent of sending.
