Abstract

The utility model discloses an ink box with balanced pressure aiming at providing an ink box with simple structure, big ink capacity, convenient manufacturing and low cost which comprises an ink containing groove shaped like an open box, an ink outlet opening extruded and connected with the printer ink supply needle and arranged on the lower side face of the ink containing groove, an ink outlet device arranged inside the ink outlet opening, an air outlet opening communicated with the ink containing groove and disposed on the upper side face, a interlayer arranged below the air inlet opening and separated into at least two chambers, sponge chamber and a buffering chamber by a clapboard, the one near the air inlet opening is the sponge chamber which is provided with a cellular material absorbing the ink, a notch is arranged at the lower end of the clapboard to communicate the sponge chamber and the buffering chamber, a notch is arranged at the upper end of the buffering chamber to communicate the inner chambers of the ink contain groove and the buffering chamber, a plastic thin piece covers and confines the outer surface of the opening side of the ink contain groove to form a confined ink containing groove.

Description

The ink cartridge that weighing apparatus is pressed

Technical field

The utility model relates to the print cartridge that ink-jet printer is used, and relates in particular to an outer framework and ink cartridge in the combined type print cartridge of ink cartridge monochromatizing or polychrome is installed in the framework outside.

Background technology

Some combined type print cartridges have appearred in the market, it by the print cartridge frame be placed in the print cartridge frame ink cartridge only single or many and form, in use after using up, can adopt by the ink in the ink cartridge way of changing ink cartridge, the print cartridge frame and on element still can continue to use, can continue by the method for changing this kind ink cartridge to use after any therein ink of the combined type print cartridge of polychrome used up, can reduce use cost, reduce unnecessary waste, reduce infringement again environment.But all be full of mandruka in the general ink cartridge,, can often in use the ink in the sponge can not be used up, also reduced the groundwater increment of ink, reduce the service life of ink cartridge, caused waste to stop following of ink freedom.

The utility model content

The utility model provides a kind of simple in structure, the ink cartridge that the weighing apparatus that ink capacity is big, easily manufactured, cost is low is pressed.

In order to achieve the above object, the utility model is achieved through the following technical solutions: comprise the ink tank that opening is box-like, on the downside of ink tank, be shaped on the outstanding ink outlet port that joins with the printer ink-providing pin, device for ink is housed out in the ink outlet port, on upper side, be shaped on the ink tank in the air admission hole that is interlinked to the outside, it is characterized in that being shaped on interlayer below the described air admission hole, interlayer is separated at least two chambers by dividing plate, spongocoel and cushion chamber, closely air admission hole is spongocoel, be placed with the porous material of blotting in the spongocoel, the lower end of dividing plate has breach, and spongocoel and cushion chamber are communicated, the upper end of cushion chamber has short slot, cushion chamber is communicated with the inner chamber of ink tank, on the outer surface of ink tank open sides, have the thin slice of polymer to cover and sealing, form airtight ink tank.

According to the ink cartridge that the weighing apparatus of such scheme manufacturing is pressed, just in the sponge storehouse, be placed with the porous material of fritter blotting, in whole ink tank, all irritated ink.Cushion chamber does not directly contact the ink in the ink tank with the porous material of blotting, prevent that ink from overflowing from air admission hole.Has ink utilization rate height, ink cartridge long service life, the use amount of minimizing porous material, the advantage of reduction manufacturing cost.

Description of drawings

Figure is the stereogram of the ink cartridge of weighing apparatus pressure.

Among the figure: 1, ink tank; 2, ink outlet port; 3, go out device for ink; 4, air admission hole; 5, interlayer; 6, dividing plate; 7, spongocoel; 8, cushion chamber; 9, sponge; 10, breach; 11, short slot; 12, thin slice; 13, inner chamber.

The specific embodiment

The utility model will be further described below by embodiment and accompanying drawing.

As seen from the figure, ink cartridge is the box-like ink tank 1 of an intermediate hollow opening, on the downside of ink tank 1, be shaped on the outstanding ink outlet port 2 that joins with the printer ink-providing pin, device for ink 3 is housed out in the ink outlet port 2, on upper side, be shaped on ink tank 1 in the air admission hole 4 that is interlinked to the outside, below air admission hole, be shaped on interlayer 5, interlayer 5 is separated into two chambers by dividing plate 6, spongocoel 7 and cushion chamber 8, closely air admission hole 4 is spongocoel 7, be placed with sponge 9 in the spongocoel 7, the lower end of dividing plate 6 has breach 10, and spongocoel 7 and cushion chamber 8 are communicated, the upper end of cushion chamber 8 has short slot 11, cushion chamber 8 is communicated with the inner chamber 13 of ink tank 1, on the outer surface of ink tank 1 open sides, have the thin slice 12 of polymer to cover and sealing, form airtight ink tank 1.
