Abstract
The utility model discloses a sealing element for an ink-jet printer cartridge. The sealing element for the ink-jet printer cartridge comprises a cylindrical main body matched with an ink outlet hole of the cartridge in shape, wherein one end face of the cylindrical main body is provided with a first opening, and the other end face is provided with a second opening, a diameter of the second opening is closely matched with an ink-supplying needle of a printer, the diameter of the first opening is bigger than the diameter of the second opening, and a through-hole with the diameter being gradually narrower from the first opening to the second opening is arranged inside the cylinder main body. When the ink-supplying needle of the printer enters the cartridge through the sealing element, the ink-supplying needle can be accurately inserted into the second opening under the guidance of the through-hole, and therefore a sealing structure of the ink-supplying needle and the second opening is formed. The sealing element for the ink-jet printer cartridge has the advantages of being capable of conveniently forming a closely matching relationship with the ink-supplying needle, ensuring good ink-supplying performance of the cartridge, and further guaranteeing printing effect of the printer.
Description
Technical field
The utility model belongs to the ink-cases of printers technical field, is specifically related to the seal that a kind of ink-jet printer cartridge uses.
Background technology
One of common inking mode between ink-jet printer and its supporting print cartridge; Be to insert in the print cartridge ink outlet port through the ink supply pin that will have black fluid through-hole; The ink supply pin is through seal, makes black liquid flow into from ink outlet port that the mode of the black fluid through-hole the ink supply pin realizes.In order to reach good ink supply effect, print cartridge must guarantee that when mounted seal can cooperate with the ink supply pin well, in case both cooperate and badly just can directly have influence on printing effect.
Summary of the invention
To the problems referred to above, the seal that the utility model provides a kind of ink-jet printer cartridge to use, the print cartridge of having used this seal can cooperate with the ink supply pin well, guarantees that printer has good printing effect.
The utility model is that the technical scheme that its technical problem of solution is adopted is:
The seal that a kind of ink-jet printer cartridge uses; Comprise cylinder body with print cartridge ink hole form fit; One end face of said cylinder body is provided with first opening, and the other end is provided with second opening, and the diameter of second opening and printer ink-providing pin closely cooperate; The diameter of first opening is greater than second opening, and the inside of cylinder body is provided with the through hole that diameter shrinks to second opening from first opening gradually.
As preferred embodiment; Said through hole increase and point to first horn mouth, second horn mouth of first opening gradually by radius and be located at first horn mouth and second horn mouth between the 3rd opening form; First bell-mouthed narrow connects second opening; A wide end that connects the 3rd opening, the other end of the 3rd opening connects the second bell-mouthed narrow portion, and second bell-mouthed wide connects first opening.
As preferred embodiment, the sidewall of cylinder body is provided with first sealing flange along the cylinder body circle distribution.
As preferred embodiment, the end face that cylinder body is provided with second opening is provided with second sealing flange around second opening.
As preferred embodiment, seal is the silica gel integrated formed structure.
The beneficial effect of the utility model is: when the printer ink-providing pin got into print cartridge through seal, it can be properly inserted in second opening under the guiding of through hole, thus the hermetically-sealed construction of the formation and second opening.The utility model can form the relation of closely cooperating with the ink supply pin easily, guarantees that print cartridge has good ink supply performance, further guarantees the printing effect of printer.
Description of drawings
Further explain below in conjunction with the accompanying drawing and the specific embodiment:
Fig. 1 is the overall structure profile of the utility model.
The specific embodiment
With reference to Fig. 1; The seal that a kind of ink-jet printer cartridge uses comprises and the cylinder body 1 of print cartridge ink hole form fit that one end face of said cylinder body 1 is provided with first opening 2; The other end is provided with second opening 3; The diameter of second opening 3 and printer ink-providing pin closely cooperate, and the diameter of first opening 2 is greater than second opening 3, and the inside of cylinder body 1 is provided with the through hole 4 that diameter shrinks to second opening 3 from first opening 2 gradually.The general employing of the utility model processed than the material of softness and flexible, and in some preferred embodiments, seal is the silica gel integrated formed structure, and this structure fabrication is convenient, be convenient to sealing and cracky not.The utility model is welded with on first opening and seals film in use, and the end face that is provided with first opening then can be used as the level reference of assembling effect when assembling.
Continuation is with reference to Fig. 1; Through hole 4 increase gradually by radius and point to first horn mouth 5, second horn mouth 6 of first opening 2 and be located at first horn mouth 5 and second horn mouth 6 between the 3rd opening 7 form; Narrow of first horn mouth 5 connects second opening 3; A wide end that connects the 3rd opening 7, the other end of the 3rd opening 7 connects the narrow portion of second horn mouth 6, and wide of second horn mouth 6 connects first opening 2.Said structure is equivalent to before, during and after through hole end big opening, split shed and little opening is set respectively; Its medium and small opening cooperates with the ink supply pin closely; Guarantee normal blotting, big opening and split shed guarantee that then the printer seal can waltz through the printer ink-providing pin.
In order to guarantee that seal can be seated; The sidewall of cylinder body 1 is provided with first sealing flange 8 along cylinder body 1 circle distribution; Seal can cooperate with print cartridge ink hole inwall well after being provided with above-mentioned flange, organizes ink to flow out from the edge.In addition, the end face that cylinder body 1 preferably is provided with second opening is provided with second sealing flange 9 around second opening 3, and this flange and print cartridge spool closely cooperate, and avoid ink infiltrate seal to flow to sealing on the film of first opening one side.
The embodiment of the utility model is not restricted to the described embodiments, as long as it reaches the technique effect of the utility model with essentially identical means, all should belong to the protection domain of the utility model.
