Abstract
A print cartridge of an ink jet printer comprises a cartridge body (1) and a surface cover (2) connected with the cartridge body (1). An air inlet (3) and an inlet air cushion chamber (5) communicated with the air inlet (3) are arranged in the cartridge body (1), a vent (4) is formed in the surface cover (2), the inlet air cushion chamber (5) is communicated with the vent (4) via an airway (6), and the air inlet (3) is provided with a teflon filling column (7). Compared with the prior art, due to effects of the inlet air cushion chamber, the airway and the teflon filling column, external air can only slowly penetrate into an ink cavity instead of entering the ink cavity rapidly, so that the ink cavity is in a micro vacuum state; under effect of the atmospheric pressure, ink does not naturally flow out of a printhead, and thus, the utilization rate of ink in the ink cartridge is higher; and an ink outlet is simpler in structure and includes fewer components, and ink obstruction is less likely to occur.
Description
Technical field
The utility model relates to a kind of ink-jet printer cartridge.
Background technology
At present, ink in ink-jet printer cartridge is ejected on the media such as paper, be shaped word or pattern by printhead, this just needs the controlled ejection of ink, and the print cartridge of the ink-jet printer overwhelming majority is on the market all on printhead top, and this just can naturally flow out because of gravity ink from printhead.The solution of prior art ink-jet printer cartridge has two kinds: 1) in print cartridge outlet, add sponge or other porous material, by the loose structure absorption ink of sponge and other porous material, so that ink does not naturally flow out from printhead; 2) at ink box ink outlet, add valve mechanism, by valve, stop ink naturally to flow out from printhead.But first method exists the utilization rate of ink lower, and has all the time residual ink in sponge, the situation that easily causes ink outlet port to stop up once air-dry; And the ink box ink outlet structure of second method is more complicated, parts are more, therefore there is the problem that packaging efficiency is lower and preparation cost is higher.
Utility model content
The utility model provides a kind of ink utilization rate higher for above problem, and ink outlet port structure is simple, parts are less and not susceptible to plugging ink-jet printer cartridge.
The utility model overcomes the above problems technical scheme used: a kind of ink-jet printer cartridge is provided, it comprises box body and cover, described cover is connected with box body, in described box body, be located at air admission hole, described cover is provided with passage, is provided with air inlet cushion chamber in described box body, and described air inlet cushion chamber is communicated with air admission hole, and air inlet cushion chamber is communicated with passage by airway, in described air admission hole, be provided with polytetrafluoroethylene (PTFE) packed column.
Adopt after above structure, compared with prior art, the utility model is owing to being provided with air inlet cushion chamber, air inlet cushion chamber is communicated with passage by airway, and in air admission hole, be provided with polytetrafluoroethylene (PTFE) packed column, after printing head is printed, ink in box body reduces, and at air inlet cushion chamber, under the effect of airway and polytetrafluoroethylene (PTFE) packed column, extraneous air is difficult for entering into fast in inking chamber, can only be penetrated into slowly in inking chamber, and then make in inking chamber in micro-vacuum state, under atmospheric effect, ink just can naturally not flow out from printhead yet, also original sponge and valve mechanism have just been saved simultaneously, therefore can make the ink utilization rate in print cartridge higher, and ink outlet port structure is simpler, parts are less, more be not prone to the situation of obstruction.Therefore the utlity model has ink utilization rate higher, ink outlet port structure is simple, parts are less and not susceptible to plugging feature.
As improvement, between described passage and air admission hole, the extended line of line and the side of box body intersect, and described airway extends along the side of box body; After arranging like this, airway is relatively long, makes the speed of air inlet slower, and then makes inking chamber can guarantee the micro-vacuum state of longer time, further improves stability in use of the present utility model and reliability.
As further improvement, in described box body, be provided with cross buffering isolation strip, described buffering isolation strip is provided with back-up block, the upper surface of described back-up block and cover laminating; After cushioning isolation strip and arranging, make the ink in inking chamber be difficult for rocking, make in use, the vibrations in print procedure are less on ink impact; And after back-up block arranges, more not yielding while making cover stressed, intensity is higher, can effectively prevent the situation that cover crushes, and makes stability in use of the present utility model and better reliability.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model ink-jet printer cartridge.
As shown in the figure: 1, box body, 2, cover, 3, air admission hole, 4, passage, 5, air inlet cushion chamber, 6, airway, 7, polytetrafluoroethylene (PTFE) packed column, 8, buffering isolation strip, 9, back-up block.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, a kind of ink-jet printer cartridge, it comprises that box body 1 and cover 2(also comprise other parts certainly, but owing to not relating to the inventive point of the invention, therefore do not repeat them here), described cover 2 is connected with box body 1, in described box body 1, be located at air admission hole 3, described cover 2 is provided with passage 4, in described box body 1, be provided with air inlet cushion chamber 5, described air inlet cushion chamber 5 is communicated with air admission hole 3, the sidewall of general air admission hole 3 is provided with opening and is communicated with air inlet cushion chamber 5, and air inlet cushion chamber 5 is communicated with passage 4 by airway 6, described air admission hole 3 is provided with the shape of the general polytetrafluoroethylene (PTFE) packed column of polytetrafluoroethylene (PTFE) packed column 7(to be determined according to the shape of air admission hole).
Between described passage 4 and air admission hole 3, the extended line of line and the side of box body 1 intersect, be that between passage 4 and air admission hole 3, line can form triangle with two sides of box body 1, described airway 6 extends along the side of box body 1, and airway 6 is that box body 1 upper surface groove and cover 2 lower surface laminatings form.
In described box body 1, be provided with cross buffering isolation strip 8, buffering isolation strip 8 is arranged in inking chamber, described buffering isolation strip 8 is provided with back-up block 9, general spacing for opposite lid 2, back-up block 9 upper surfaces are also provided with projection, and cover 2 lower surfaces directly over soil block are provided with and projection groove one to one, the upper surface of described back-up block 9 and cover 2 laminatings, fit in the lower surface of the upper surface of back-up block 9 and cover 2.
Above embodiment is only preferred embodiment of the present utility model, and the utility model is not limited only to above embodiment and has also allowed other structural change, allly in the utility model rights to independence claimed range, changes, and all belongs to the utility model protection domain.
