Abstract
The utility model relates to an ink box for an ink-jet printer which comprises a box body, wherein the box body is provided with an ink storing cavity, a negative pressure cavity, a gas inlet and an ink supplying port, wherein the ink storing cavity is further internally provided with a constant pressure mechanism capable of stabilizing the negative pressure in the ink storing cavity. As the ink storing cavity is internally provided with the constant pressure mechanism which can stabilize the negative pressure in the ink storing cavity, when the pressure in the ink storing cavity is increased due to changes, such as the increase of the temperature of the outer environment and the like, the constant pressure mechanism can adjust the flow of gas, and leads the flow of the gas to be more stable, thereby avoiding the phenomena of ink dropping and color mixing when printing, improving the printing quality, and solving the technical problems of the ink box of the ink-jet printer such as ink drooping in an idle mode, color mixing when printing and unstable printing quality due to changes, such as the increase of the temperature of the outer environment and the like.
Description
Technical field
The utility model relates to the print cartridge that a kind of ink-jet printer uses.
Background technology
In the existing ink-jet printer cartridge, a kind of like this print cartridge is arranged, it has spongocoel, air chamber and ink storage chamber, be provided with ink outlet port in the spongocoel bottom, inking chamber top is provided with air admission hole, in addition, is provided with elongated and circuitous capillary ink pipeline at the outer wall of ink storage chamber and spongocoel, ink flows to spongocoel and then flows to ink supply port by wherein during printing.For this class print cartridge, the problem that exists is, after the installation, its serviceability is subjected to influence that ambient temperature changes very greatly, and especially when environment temperature raises, airtight when gases are heated, they expand and can't be from the discharge of ink channel hole (owing to high hydraulic pressure of inking chamber) at the top in the spongocoel, thereby make spongocoel produce malleation ink is pressed to ink outlet port downwards, finally ooze out, cause the print quality instability of image, have standby to drip bad phenomenon such as China ink, printing colour mixture and take place from printhead.
The utility model content
The print cartridge that the utility model provides a kind of ink-jet printer to use causes standby to drip China ink, prints colour mixture and the unsettled technical problem of print quality because of being subjected to variations such as ambient temperature rising with the print cartridge that solves existing ink-jet printer use.
In order to address the above problem, the technical scheme that the utility model provides is:
The print cartridge that a kind of ink-jet printer uses comprises box body, and described box body is provided with ink storage chamber, negative pressure cavity, air inlet and ink supply port, it is characterized in that, described ink storage also is provided with the constant voltage mechanism that can stablize negative pressure in the ink storage chamber in the chamber.
Described constant voltage mechanism is arranged on the constant voltage chamber that communicates with air inlet between ink storage chamber and the negative pressure cavity, described constant voltage chamber bottom is provided with connection chamber, described connection chamber be provided with first opening that is communicated with ink storage chamber respectively, with being communicated with second opening and being communicated with the 3rd opening with negative pressure cavity of constant voltage chamber.
Described box body comprises drain pan and cover, and the lateral wall of described drain pan is provided with the capillary channel that ink storage chamber is communicated with negative pressure cavity, and described cover is provided with the elongated circuitous air slot that communicates with air inlet.
Described constant voltage chamber and negative pressure cavity are separately positioned on the both sides in described ink storage chamber.
Described negative pressure cavity is a spongocoel.
After having adopted technique scheme, owing to increased the constant voltage mechanism that can stablize negative pressure in the ink storage chamber in the ink storage chamber.When print cartridge causes ink storage cavity pressure to increase because of being subjected to variations such as ambient temperature rising, flowing of constant voltage mechanism energy adjustments of gas, make gas flow more steady, disappear thereby make to drip China ink and print mixed color phenomenon, improve print quality, the print cartridge that has solved existing ink-jet printer use causes standby to drip China ink, prints colour mixture and the unsettled technical problem of print quality because of being subjected to variations such as ambient temperature rising.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
First embodiment:
Referring to Fig. 1 and Fig. 2, toner cartridge main body of the present utility model comprises a drain pan 1 and a cover 2, and Fig. 2 is the profile of the print cartridge drain pan among Fig. 1.As seen from Figure 2, comprising 4 cavitys that opening is arranged in the drain pan 1, is ink storage chamber 12, constant voltage chamber 13, spongocoel 4 and air chamber 5 from left to right successively.Ink supply port 10 is arranged at the bottom of spongocoel 4, and the ink in the print cartridge therefrom flows out the supply printhead, is used for implementing to print.Cover 2 is combined as a whole with the mode of drain pan 1 with welding, thereby four atriums of drain pan 1 are sealed.On the outer wall of drain pan 1, be provided with circuitous ink guide tank 3 (as shown in Figure 1), be communicated with ink storage chamber 12 and spongocoel 4, ink is flowed through wherein.Wherein the bottom of ink storage chamber 12 directly is communicated with the connection chamber 7 of the bottom in constant voltage chamber 13 by a first passage mouth 6; Constant voltage chamber 13 is communicated with connection chamber 7 by a second channel mouth 8 of its bottommost; The right of connection chamber 7 has a third channel mouth 9 to be communicated with a four-way road junction 11 of ink guide tank 3, and ink enters spongocoel 4 by four-way road junction 11.Part to ink storage chamber 12 and spongocoel 4 above the cover 2 has pouring ink hole and air admission hole (not shown on the accompanying drawing) respectively.
When the arrow among Fig. 2 is illustrated in printer prints, the flow direction of air 14 in the print cartridge.In the utility model, air 14 is entered in the air chamber 5 of print cartridge through tiny circuitous air slot (not shown on the accompanying drawing) and the gas port (not shown on the accompanying drawing) that is provided with in the cover 2 by the air admission hole on the cover 2, and then flows in the constant voltage chamber 13 by another air slot on the cover 2.During printing, ink flows to the ink guide tank 3 by first passage mouth 6 from ink storage chamber 12, flow into four-way road junction 11 by third channel mouth 9 along the ink guide tank 3 that leads to spongocoel 4 upper ends, then enter spongocoel 4, from ink supply port 9 toward print head of spongocoel 4 bottoms.In the print procedure, consumption along with ink, air can be from constant voltage chamber 13 enters connection chamber 7 by second channel mouth 8 and then enters ink storage chamber 12 and replenish, after ink in the ink storage chamber 12 then enters connection chamber 7 from first passage mouth 6, enter spongocoel 4 again, thereby guarantee the continuation of print job, simultaneously, according to pressure balance principle, negative pressure appears in the top in the ink storage chamber 12, the ink height that the constant voltage chamber is 13 li then can maintain the height of the upper edge of first passage mouth 6, has bigger negative pressure in the spongocoel 4 thereby make.
