Abstract

The utility model discloses a reusable printer cartridge capable of being continuously injected with ink. The printer cartridge comprises an upper cover, an internal air control apparatus and an external cartridge. The upper cover comprises an ink injecting port and an air inlet. The air inlet is tightly connected to the internal air control apparatus through a thin pipe. An air intake A is formed in the center of an intake hood. The air control apparatus comprises three parts: an intake hood on the left, an air control valve in the middle and an outtake hood on the right. The peripheral circumference sizes of the three parts are consistent, and the three parts are connected with one another tightly. A semicircular spherical surface is protruded rightward on the center of the right part of the intake hood. The center of the spherical surface is in corresponding contact with that of the air control valve. A flat round face is protruded leftward on the center of the air control valve. The area of the round face is larger than that of the air intake A. The periphery of the round face is provided with a circlar impression. A groove extended in the vertical direction is arranged in the left side of the outtake hood and is connected with an air outlet B on the top of the outtake hood. The advantages of the printer cartridge are that: the ink can be injected continuously, the repeated use is convenient, the printing cost is reduced, the work is stable, the printhead is not easy to dry and block, and the environmental protection and energy saving are benefited.

Description

One is the reusable ink-cases of printers of ink continuously

Technical field

The utility model is the one reusable ink-cases of printers of ink continuously, belongs to printing technique field.

Background technology

The print cartridge using on ink-jet printer is all disposable print cartridge conventionally, and in the time that the ink in print cartridge is finished, print cartridge is just changed by entirety thereupon, as user arbitrarily abandons old print cartridge, is easy to cause environmental pollution.Even if there is user to want to save, the ink of doing it yourself, also because there are filler or the design of mazy air pressure in print cartridge inside, and cannot reach the reusable effect of ink, so just greatly increase printing cost, a large amount of wastes that also caused print cartridge to produce material.Larger because filler in ink box warehouse is more or mazy air pressure design takes up room, the ink that can store in ink box warehouse is little, and it is complete that ink is easy to volatile dry, thereby cause printer head plugging fault more.On market, also there is the external continuous ink feeding print cartridge of exploitation, this print cartridge is for also having certain practicality with the machine of printhead, but because of its ink-feeding tube longer, add that temperature influence is larger, its fault rate is very high, and its external part to take office space larger, cumbersome when random device moves together, also affect the overall appearance of machine; For the machine with printhead not, except the problems referred to above, this print cartridge is difficult to realize the ideal effect of upper machine work, and its practicality is very poor.

Utility model content

The purpose of this utility model is to provide the one reusable print cartridge of ink continuously, has both reduced and has printed cost, saving resource, does not also pollute the environment.

The technical solution of the utility model is: a kind of reusable print cartridge of ink continuously, this print cartridge is made up of upper cover, inner control device of air and outside ink box warehouse.Above upper cover, have ink filling port and air admission hole with stopper, air admission hole is sealably coupled in inner control device of air by tubule, in the airscoop shroud portion of control device of air, is formed centrally air inlet A.Control device of air comprises three parts: left side is airscoop shroud, and centre is control valve, and right side is air leaving cover, and three's peripheral circumferential is in the same size, is tightly connected.Have to the right the semicircle sphere of projection in centre, airscoop shroud right side, air inlet A is just in the center of sphere, the contact corresponding to the center of control valve of the center of this semicircle sphere.The center of control valve is protruding left smooth disc, and this disc is greater than the area of air inlet A, and disc is with circular impression outward.There is the groove of downward-extension in the left side of air leaving cover, is connected, then by the tubule connecting, gas outlet B is extended to the bottom of print cartridge warehouse, simultaneously the channel connection of gas outlet B also and between airscoop shroud and control valve with the gas outlet B on its top.Whole inner control device of air is positioned in ink box warehouse after realization sealing.Ink box warehouse is exactly the part of the carrying ink that matches with printer on the market, and the inside does not just have other fillers, ink that so just can be a large amount of except laying control device of air.

The utility model course of work and principle are: open ink filling port ink, after filling it up with, load onto plug closes.Under print state not, the center disc of control valve is tightly attached on the semicircle sphere of airscoop shroud right side projection, by air inlet A sealing, the air outside print cartridge can not be entered, whole inner control device of air is in closure state, therefore the ink in ink box warehouse also can not outflow.Under print state, the ink-jet outlet of print cartridge bottom is opened, ink in print cartridge outwards sprays, the air pressure of its print cartridge inside reduces, external pressure is constant, at this moment original air pressure balance is destroyed, the outside relative print cartridge of air pressure inside is higher, the air of print cartridge outside just enters into airscoop shroud by the air admission hole above covering like this, by air inlet A to control valve power to the right, after stress deformation, the center of control valve will be passed to the right, at this moment air inlet A and gas outlet B will be communicated with, whole control device of air is just in open mode, the air of outside just constantly enters in ink box warehouse.Along with the increase of the air capacity entering, in the time that the air pressure in print cartridge is equal with ambient pressure, control valve will return to original position left, and its center disc is again by air inlet A sealing, and whole control device of air is again in closure state.So go round and begin again, print cartridge just can be in normal duty, does not just need like this other filler or labyrinth channel to control flowing and having transported ink of air, for ink box warehouse storage ink has been saved large quantity space in print cartridge warehouse.In the time that ink is finished, can take off the stopper of ink filling port, to ink in print cartridge, add after good and also use plug closes, whole like this print cartridge just can be realized and add continuously China ink and reused.

The print cartridge that the utility model is configured to, tool has the following advantages compared with existing print cartridge: continuously ink, conveniently reuse, reduce and print cost, working stability and be not easy the dry printhead that stops up, be conducive to environmental protection and energy-conservation, can produce good Social benefit and economic benefit.
