Abstract

The utility model relates to an ink supplementary device of ink-jet printer's ink box. An egress of a used ink box is stuck with a paster and is sealed by a protecting clip. The ink box is provided with a through hole outer margin. The utility model is characterized in that an ink feeding pipe structure in the short cone shape at the front end of the ink feeding barrel is connected and combined with an ink feeding through hole of the ink box. An auxiliary combination composed of an auxiliary plug and an auxiliary pad can also be adopted. The circular plate on the upper part of the ink feeding barrel is pushed to move up and down for many times; therefore, the ink containing chamber of the ink feeding barrel generates the negative pressure through which the air in the ink box containing chamber can do the current exchange with the ink in the ink feeding barrel. The air can be expelled from the ink holding sponge in the containing chamber and then the ink can filter into the space of the ink holding sponge.

Description

The ink replenishing device of ink-jet printer China ink casket

The utility model relates to a kind of ink replenishing device of black casket, refers to a kind of ink replenishing device of ink-jet printer China ink casket especially.

At traditional ink-jet printer, be ink feed by black casket, ink is injected into ink droplet on the printing paper via spray orifice via the eruption device, when the ink in this China ink casket uses, directly change black casket, can continue to print; By the black casket of former factory supply, because of the suitable height of price, suitable big of printing person's financial burden in a large number.

Ink-jet printer China ink casket known can be equipped with balance air bag in black casket master room inside usually, or with sponge absorption ink, normal supply ink when printer prints is provided; The black casket that former factory provides when ink is filled, is to cooperate the automated production operation, and black casket master room inside all can reach pressure balance, does not have the ink leak situation during printing.

Replenish ink at the black casket of known sky, when this China ink casket master room inside is provided with balance air bag, can use adhesive tape in advance, the air-vent that black casket base plane is deflected passage touch, prevent the ink that injects thus path spill; In addition, paste an adhesive tape, prevent that air bag is compressed and loses the pressure balance effect in the position of the top of black casket air bag air admission hole; With the ball pressurization of a sharp object, ball is pushed away seat surface again, ball is pushed away seat surface, form an ink filling port towards the top sealing of black casket; Draw an amount of ink with injection tube, the ink filling port through black casket top slowly injects, till filling with; Seal the ink filling port of black casket top with a plug, tear the adhesive tape of air bag air admission hole position, black casket top and black casket bottom again and deflect adhesive tape on the channel plane; Often when tearing the adhesive tape of black casket base plane off, can produce the ink leak situation at the port that deflects passage or nozzle location, it is former because black casket master room internal pressure can't obtain balance, annotated China ink after, the ink that has only slowly wiping to overflow is till black casket can not ink leak.

Adsorb the black casket of ink known with ink storing sponge, when the black casket of sky carries out ink replenishing, can paste driving fit through paster at the port in exit usually; Again in the center through hole of black casket lid upper limb face with the film sealing, draw an amount of ink through injection tube, expose the below of through hole outer rim film with the elongated shape needle tubing to room, ink is injected room; But the ink storing sponge in this room is because of containing a large amount of bubbles, directly the ink that injects can't be got rid of air, the amount that causes the ink injection is very limited, and store up in the black room and second room and be provided with aperture plate, if the air in second room can't be discharged, the ink that stores up in the black room also can't normally enter second room via aperture plate, and the guiding ink is to the room that erupts device.

Be loaded into the black casket on the printer, can't continue to provide when printing, main cause is to be that the eruption device of printhead inside can't obtain the lasting supply of ink, the passage that the ink importing carrier of no capacity defines causes, promptly be, be to enter too much air in second room of printhead inner edge, air is led to ink eruption device storage chamber and produces disconnected black situation, cause and cause the eruption device not have the situation that ink can spray, as erupt device and do not have situation that ink can spray and continued when of a specified duration, this eruption device has the worry of burning.

The ink replenishing device of No. 97230248.4 and No. 97252034.4 ink-jet printer China ink casket of the Chinese patent of before the applicant, being created, its be the utilization ink bottle refilling Guan Yumo casket pouring ink hole between the driving fit structure, utilize fashion of extrusion that the ink in the ink bottle is injected the black room of storage, when loosening ink bottle, the tension force that has with ink bottle, with the air sucking-off in the ink storing sponge, ink is injected the ink storing sponge room of black casket.

The purpose of this utility model is the ink replenishing device that a kind of ink-jet printer China ink casket will be provided, and the refilling tube of this device combines with black casket grafting, fast the air in the room ink storing sponge is discharged, and replenishes the space that ink infiltrates ink storing sponge.
