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 comprises an air channel and a constant-pressure cavity arranged at the bottom of the ink storage cavity. One end of the air channel is connected with the air inlet and the other end thereof is connected with the constant-pressure cavity; and a porous material is arranged inside the constant-pressure cavity. The porous material is arranged inside the constant-pressure cavity which has a size smaller than that of the ink storage cavity, so that even if the constant-pressure cavity is filled with the porous material, the amount of the porous material is not large, thereby having small ink absorption amount and reducing amount of the remaining ink after the ink box is used up.
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, Sponge is inserted in adopting as shown in Figure 1 usually in ink storage chamber by negative pressure mechanism, keeps ink by the capillary effect of Sponge; Because built-in cavernous body is full of ink storage chamber and characterization of adsorption, printer can not blot the ink in the sponge only fully, print cartridge uses up the ink that also remains more amount in the sponge of back, the sponge volume is big more, the ink residual volume is many more, most of ink remains in and causes waste in the sponge, also increases user's use cost.
The utility model content
The utility model provides a kind of print cartridge that is used for ink-jet printer, the wasting technical problem to solve the ink that also remains more amount after the existing print cartridge that is used for ink-jet printer uses up.
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, it is characterized in that, described negative pressure mechanism comprises air duct and is arranged at the constant voltage chamber of ink storage chamber bottom, air duct one end is connected with air admission hole, the other end communicates with the constant voltage chamber, and constant voltage is provided with porous material in the chamber.
Described porous material is the porous material of filter screen class.
Described air duct is set to labyrinth type near the air inlet nose end.
The end that described air duct communicates with the constant voltage chamber is positioned at the bottom in constant voltage chamber.
After having adopted technique scheme, because negative pressure mechanism comprises air duct and is arranged at the constant voltage chamber of ink storage chamber bottom, air duct one end is connected with air admission hole, the other end communicates with the constant voltage chamber, porous material is arranged in the very little constant voltage chamber of volume volume with respect to ink storage chamber, therefore, even be full of the porous material of absorption in it, porous material also seldom, the blotting amount is also very little, reduce print cartridge and used up the back amount of ink remaining, solved the ink that also remains more amount after the existing print cartridge that is used for ink-jet printer uses up and wasting technical problem.Secondly, be the filter screen class owing to adopted porous material, and therefore the general blotting not of the porous material of filter screen class, has further reduced print cartridge and has used up the back amount of ink remaining.At last, because air duct is set to labyrinth type near the air inlet nose end, can prevent that the ink accident from overflowing from air duct, protection print cartridge outward appearance is not contaminated.
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 ink storage chamber, 2 air admission holes, 3 ink outlet ports, 4 air ducts, 5 constant voltage chambeies, 6 porous materials, 7 cavernous bodies.
The specific embodiment
As shown in Figure 2, a kind of print cartridge that is used for ink-jet printer comprises that the air duct 4 that is used to store ink is set to labyrinth type near the air inlet nose ends.During manufacturing, air duct 4 forms by cartridge body forming tank and the welding of envelope film.The porous material 6 of filter screen class also is fixed in the constant voltage chamber by welding manner.When printer is worked, the ink of ink storage chamber 1 is taken away a part, will form negative pressure to a certain degree in the cartridge body, end by air duct 4 enters cartridge body inside to air from the external world immediately, but because the other end of air duct 4 is immersed in the constant voltage chamber, the constant voltage chamber is welded with the porous material 6 of filter screen class, and be in the bottom of ink storage chamber 1, so air must overcome the ink hydraulic pressure in constant voltage chamber 5 and surface tension that ink acts on the porous material micropore just can enter, the volume of air that causes covering ink storage chamber 1 is always taken the volume of ink away less than the machine of being printed, make print cartridge inside be in negative pressure state all the time.Because cartridge body constant voltage chamber 5 and ink storage chamber 1 are with separated, the proportion of air is littler than ink, and air can directly enter ink storage chamber 1 from constant voltage chamber 5, and the ink in constant voltage chamber 5 can not enter ink storage chamber.Along with the ink of ink storage chamber 1 is consumed, and the ink in constant voltage chamber 5 does not reduce all the time, ink can cover porous material 6 always, the negative pressure that has guaranteed print cartridge inside is in a steady state, and as long as cover porous material 6 with ink, just can guarantee that negative pressure is constant in the print cartridge, the ink in constant voltage chamber 5 does not just need a lot, has reduced the print cartridge residual volume and can well guarantee the print quality of print cartridge.
