Abstract
The utility model relates to an ink box used in an inkjet printer, which comprises an ink storage cavity for storing ink, an air inlet which keeps a pressure balance with the external pressure, and an ink exit and a negative pressure mechanism providing ink to the printing head of a printer. The negative pressure mechanism is a capillary pipe with one end being communicated with the air inlet; the ink storage cavity is divided into a first ink storage cavity and a second ink storage cavity by a separation board with a gap; the other end of the capillary pipe is positioned at the bottom of the first ink storage cavity; and the ink exit is formed at the bottom part of the first ink storage cavity. Along with the consumption of the ink in the second ink storage cavity, the ink inside the first ink storage cavity is not reduced, so that the negative pressure at the bottom part of the ink box is in a constant state, and can not vary with the decrease of the ink amount.
Description
Technical field
The utility model relates to the print cartridge that is used for ink-jet printer.
Background technology
The existing print cartridge primary structure that is used for ink-jet printer comprises the ink storage chamber that is used to store ink, keeps the air admission hole of air pressure balance with external environment condition, to the ink outlet port and the negative pressure mechanism of the printhead ink supply of printer.Negative pressure mechanism makes ink in the print cartridge be in the mechanism of certain negative pressure state for the storage request that guarantees normal ink feed and ink, negative pressure mechanism adopts a capillary channel (internal diameter is less than 1mm) as shown in Figure 1 usually, insert in the print cartridge, one end links to each other with atmosphere as the air inlet of print cartridge, the other end is in print cartridge ink storage chamber bottom, when printer is worked, the ink of ink storage chamber is taken away a part, form negative pressure to a certain degree in the print cartridge, end by capillary channel enters print cartridge inside to air from the external world immediately, because the other end of capillary channel is immersed in the ink, and be in the bottom of ink storage chamber, air must overcome certain hydraulic pressure and just can enter, and causes covering the volume of air in the ink storage chamber, the ink volume of taking away less than the machine of being printed always, thus make print cartridge inside be in negative pressure state all the time.This mode is the ink of ink storage chamber (when liquid level is high) more for a long time, print no problem minimizing along with quantity of ink, the ink of ink storage chamber fewer and feweri (liquid level reduction), negative pressure in the print cartridge can be more and more littler, surface fully up to capillary channel, do not have negative pressure in the print cartridge, at this moment the certain ink of remnants in the print cartridge, the negative pressure ink that do not have in the print cartridge can ooze from printhead, thereby influences print quality and pollute printer.
The utility model content
The utility model provides a kind of print cartridge that is used for ink-jet printer, with solve the existing print cartridge that is used for ink-jet printer because of residual ink amount more after a little while owing to do not have in the print cartridge that negative pressure or negative pressure are very little to be caused ink to ooze from printhead influencing print quality and the wasting technical problem of pollution printer.
In order to solve above technical problem, the technical scheme that the utility model is taked is:
A kind of print cartridge that is used for ink-jet printer, comprise the ink storage chamber that is used to store ink, keep the air admission hole of air pressure balance with external environment condition, to the ink outlet port and the negative pressure mechanism of the printhead ink supply of printer, negative pressure mechanism is the capillary channel that an end communicates with air admission hole, it is characterized in that, described ink storage chamber is divided into first ink storage chamber and second ink storage chamber by the dividing plate that top has breach, the other end of described capillary channel is positioned at first ink storage chamber bottom, and described ink outlet port is positioned at the first storage China ink bottom.
Described capillary channel is set to labyrinth type near the air inlet nose end.
After having adopted technique scheme, because ink storage chamber has dividing plate jaggy by top and is divided into first ink storage chamber and second ink storage chamber, the other end of capillary channel is positioned at first ink storage chamber bottom, ink outlet port is positioned at the first storage China ink bottom, because of the proportion of air littler than ink, air can directly enter second ink storage chamber from first ink storage chamber, and the ink of first ink storage chamber can not enter second ink storage chamber; Along with the ink of second ink storage chamber is consumed, because of the ink of first ink storage chamber does not reduce all the time, thereby the negative pressure that has guaranteed print cartridge inside is in a steady state, can not change along with the minimizing of quantity of ink.Solved the existing print cartridge that is used for ink-jet printer because of residual ink amount more after a little while owing to do not have in the print cartridge that negative pressure or negative pressure are very little to be caused ink to ooze from printhead influencing print quality and the wasting technical problem of pollution printer.
Description of drawings
Fig. 1 is the existing structural representation that is used for the print cartridge of ink-jet printer.
Fig. 2 is a structural representation of the present utility model.
Among the figure, the implication of each sign is: 1 first ink storage chamber, 2 air admission holes, 3 ink outlet ports, 4 capillary channels, 5 second ink storage chambers, 6 dividing plates.
The specific embodiment
As shown in Figure 2, a kind of print cartridge that is used for ink-jet printer, comprise the ink storage chamber that is used to store ink, keep the air admission hole 2 of air pressure balance with external environment condition, to the ink outlet port 3 and the negative pressure mechanism of the printhead ink supply of printer, negative pressure mechanism is the capillary channel 4 that an end communicates with air admission hole, capillary channel 4 is set to labyrinth type near air admission hole 2 ends, ink storage chamber is divided into first ink storage chamber 1 and second ink storage chamber 5 by the dividing plate 6 that top has breach, the other end of capillary channel 4 is positioned at first ink storage chamber, 1 bottom, and ink outlet port is positioned at the first storage China ink bottom.Capillary channel 4 forms by cartridge body forming tank and the welding of envelope film.When printer is worked, the ink of second ink storage chamber 5 is taken away a part, will form negative pressure to a certain degree in the cartridge body, end by capillary channel 4 enters cartridge body inside to air from the external world immediately, but because the other end of capillary channel 4 is immersed in the ink of first ink storage chamber 1, and be in the bottom of first ink storage chamber 1, the ink hydraulic pressure that air must overcome first ink storage chamber 1 just can enter, so cover the volume of air of ink storage chamber, always take the volume of ink away, make print cartridge inside be in negative pressure state all the time less than the machine of being printed.Because cartridge body first ink storage chamber 1 and second ink storage chamber, 5 usefulness dividing plates 6 separate, because of the proportion of air is littler than ink, air can directly enter second ink storage chamber 5 from first ink storage chamber 1, and the ink of first ink storage chamber 1 can not enter second ink storage chamber 5; Along with the ink of second ink storage chamber 5 is consumed, because of the ink of first ink storage chamber 1 does not reduce all the time, thereby the negative pressure that has guaranteed print cartridge inside is in a steady state, can not change along with the minimizing of quantity of ink, thereby guarantees the print quality of print cartridge.
