Abstract

The utility model relates to an ink box used by an inkjet printer, which comprises a box body (1) with an ink storing chamber (6) and an ink outlet (5), and an air guide hole (4) for balancing the internal and external pressure of the ink box, wherein the ink box is characterized in that: a ventilating tube (2) is installed between the ink storing chamber (6) and the air guide hole (4); a the ventilating tube (2) is provided with micro-pore filtering membrane (7); the aperture of micro pores on the micro-pore filtering membrane (7) is ranged from 0.2 mum to 5 mum; and the ventilating tube (2) is a round tube. The ink box related to the utility model has the advantages of simple structure and reliable performance.

Description

Print cartridge

Technical field

The utility model relates to a kind of print cartridge, specifically is meant the print cartridge that a kind of ink-jet printer is used.

Background technology

In the prior art; In the print cartridge design individual combined symptoms is arranged always; Inner for the balance print cartridge on the one hand because the formed vacuum of consumption of ink; Print cartridge is inner must to communicate counterpressure with ambient atmosphere, on the other hand in order to prevent evaporation of ink and slime flux outside print cartridge, must make print cartridge keep good sealing again.A kind of technical scheme that prior art adopts is that the labyrinth passage of complex design comes air guide in print cartridge, but can not effectively prevent the evaporation of ink like this.Another kind of technical scheme commonly used is one to two black liquid cushion chamber of design and fills some porous materials (like sponge); Though such structure can prevent evaporation of ink, but still be that hermetically-sealed construction can not fundamentally solve the balanced problem of the inside and outside atmospheric pressure of print cartridge.

Summary of the invention

The utility model provides a kind of print cartridge that is used for ink-jet printer, can not realize atmospheric pressure inside and outside the balanced box and the technical problem that prevents evaporation of ink and two functions of slime flux in the box simultaneously to solve existing print cartridge.

For solving the problems of the technologies described above, the technical scheme that the utility model provides is: said print cartridge comprises the box main body that has ink storage chamber and ink outlet port, is used for the gas port of balanced print cartridge external and internal pressure; Between ink storage chamber and the gas port permeability cell is installed; Permeability cell is provided with micropore filtering film, and the micropore size on the micropore filtering film is between 0.2 micron to 5 microns.

As preferably, said permeability cell is a pipe, and this structural stability is good, and is easy for installation.

Can find out according to such scheme and the utlity model has following advantage: adopt the micro porous filtration membrane structure can need not in box main body, to be provided with mazy air guide channel; Also not be used in filling porous material in the print cartridge; Because the micropore size on the micropore filtering film is between 0.2 micron to 5 microns; Gas molecule can freely pass through; So and liquid particle can not can not be realized atmospheric pressure and the technical problem that prevents evaporation of ink in the box, two functions of slime flux inside and outside the balanced box simultaneously through effectively solving existing print cartridge, simplified the production technology of print cartridge simultaneously greatly, reduced production cost.

The specific embodiment

Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.

Provided by accompanying drawing, the utility model is the print cartridge that a kind of ink-jet printer is used, and print cartridge comprises the box main body 1 that has ink storage chamber 6 and ink outlet port 5; The gas port 4 that is used for balanced print cartridge external and internal pressure; Through the tight fit of cover 3 and box main body 1 mode of withholding permeability cell 2 is snugly fitted between ink storage chamber 6 and the gas port 4 during practical implementation, permeability cell 2 is a pipe, is provided with micropore filtering film 7 in the middle of the permeability cell 2; The micropore size on the micropore filtering film that adopts 7 between 0.2 micron to 5 microns; The thickness of micropore filtering film is between 0.05 millimeter to 0.5 millimeter, and can adopt thickness during practical implementation is 0.1 millimeter, and the aperture is 0.5 micron a micropore filtering film.

Can find out according to above embodiment: because micropore filtering film is between ink storage chamber and the gas port; Liquid ink particulate in the ink storage chamber can not pass the micropore on the micropore filtering film and gas molecule can pass freely through micropore filtering film; The utility model can effectively prevent evaporation of ink, slime flux in the box; Simultaneously because gas molecule can pass micropore, so the utility model can the inside and outside atmospheric pressure of balanced box.

Be not limited in above-mentioned embodiment based on the utility model, multiple variation can also be arranged, as directly being contained in micropore filtering film on the passage in the print cartridge and the external world through welding manner or alternate manner.The effect that they are obtained is identical.These simple structural changes still belong to the protection domain of the utility model requirement.

Claims

1. print cartridge that ink-jet printer is used, said print cartridge comprises the box main body (1) that has ink storage chamber (6) and ink outlet port (5), is used for the gas port (4) of balanced print cartridge external and internal pressure; It is characterized in that: between ink storage chamber (6) and the gas port (4) permeability cell (2) is installed; Permeability cell (2) is provided with micropore filtering film (7), and the micropore size on the micropore filtering film (7) is between 0.2 micron to 5 microns.

2. according to the said print cartridge of claim 1, it is characterized in that: said permeability cell (2) is a pipe.
