Abstract
A pressure balance device of ink cartridge, a air passage is arranged in a ink cartridge, one end of the air passage is communicated with air and the other end is immerged in the ink. The device can produce negative pressure in the ink cartridge to ensure don't happen ink leak, with simple structure, low costs and good reliability.
Description
Affiliated technical field
The utility model relates to printer, particularly the print cartridge of ink-jet printer.
Background technology
The sponge of one elasticity porous is arranged in traditional ink-jet printer cartridge, and marking ink is all adsorbed wherein.The siphonage that utilizes sponge compression back to produce during printer work arrives the shower nozzle position with ink transport.Sponge also has filtered air simultaneously, does not make air enter the effect of printer.But the existence of sponge also can produce following deficiency: because the liquid adsorption characteristic of sponge itself, quantity of ink residual after print cartridge uses up is many; Vibration in the transportation can make air move to the ink outlet port position, influences print quality; Repeat to add ink and can make bubble enter into printer,, be unfavorable for environmental protection so print cartridge can't be reused; And production cost height.
But directly remove sponge and can cause new problem again: when the gap of print cartridge in work, or quit work, or when being moved out of printer, the ink in the print cartridge can be because the gravity of self and the effect of other power, and water clock comes out.
The utility model content
Remove behind the sponge deficiency of ink leak easily in order to overcome conventional ink cartridge, the utility model provide a kind of print cartridge pressure equaliser it can make the inner negative pressure that produces of the print cartridge of removing sponge, guarantee that water clock does not take place ink.
The technical scheme that its technical problem that solves the utility model adopts is: print cartridge inside is provided with air duct, and the one end communicates with atmosphere, and the other end is immersed in the ink.
The beneficial effects of the utility model are: can make to produce suitable negative pressure in the print cartridge, guarantee that water clock does not take place ink.And simple in structure, cost is low, good reliability.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a cutaway view of the present utility model.
Fig. 2 is a right view of the present utility model.
Fig. 3 is the cutaway view of the utility model when being used in Five-colour ink cartridge.
1 air duct among the figure, 2 ink ducts, 3 ink box covers, 4 cartridge bodies, 5 ink outlet ports.
The specific embodiment
In Fig. 1 Fig. 2, air duct 1 is a circular tubule, and its end communicates with ambient atmosphere through ink duct 2.Ink duct 2 when air duct 1 overflows, can make ink preserve therebetween in the ink accident, and protection print cartridge outward appearance is not contaminated.Air duct 1, ink duct 2 all is combined on the ink box cover 3.The other end of air duct 1 is in the bottom of cartridge body 4, and is immersed in the ink fully.
When printer was worked, near the ink the ink outlet port 5 can be taken away a part, and print cartridge inside will form negative pressure (being lower than an atmospheric pressure) to a certain degree, and air enters print cartridge inside from the external world by air duct 1 immediately.But owing to the other end of air duct is immersed in the ink, and be in the bottom of cartridge body 4, just can enter so this air must overcome certain hydraulic pressure.
Because overcome hydraulic pressure, so cover the volume of air of print cartridge inside, always be less than the volume of the ink that the machine of being printed takes away, so print cartridge inside has negative pressure to exist all the time.The pressure of this negative pressure just in time equals the gravity of ink, makes the pressure differential that print cartridge is inside and outside just to reach the not degree of ink leak water.
Fig. 3 is the schematic diagram of a Five-colour ink cartridge, and the principle of pressure equaliser is with above-mentioned identical.One air duct 1 is all arranged respectively in the ink storehouse of each different colours, ink is played the effect that prevents water clock.
Claims (5)
