The novel sponge-free ink cartridge for the ink-jet printer is provided with the air guiding path directly enabling the cavity where the ink absorbing cotton to be communicated with the external atmosphere, and the air guiding path ensures normal ventilation of the ink cartridge during printing, and together with the ink jet structure of the compressed cotton core and the ink absorbing cotton, has the functions of limiting ink flow and ensuring air pressure balance inside and outside the ink cartridge, ensuring that ink does not drop from the ink cartridge, and the ink cartridge can continually and normally print.

Description

A kind of novel without the sponge ink-jet printer cartridge

Technical field

The utility model belongs to the ink-jet printer cartridge technical field, is specially a kind of novel without the sponge ink-jet printer cartridge.

Background technology

Usually be divided at the compatible print cartridge that uses on the market all the time and sponge arranged and without two kinds of structures of sponge.Wherein have the sponge structure print cartridge to occupy most ratios, it mainly is moulding, sponge, cover, cotton core, sealing gasket, retaining clip and air-guiding film that its structure forms.This have the sponge structure print cartridge to filter bubble and storage ink by sponge, and recycling is allowing ink be full of ink storage pond and nozzle under the filter screen under the condition of high vacuum, can print normally to guarantee print cartridge.But have the common sponge of sponge structure and DYE ink matching effect good, print broken string but cause sometimes on high-speed printer, fluency is good not; And also having a fatal defective, sponge can not be complementary with the PIGMENT ink usually exactly, causes the printing effect extreme difference.

Without the inner sponge that is not used for the storage ink of sponge structure print cartridge, this structure effect when being complementary with DYE and PIGMENT ink is all good.In order to guarantee that print cartridge can normal ventilation when printing, without operated by rotary motion in the sponge structure print cartridge ventilation device is arranged, but this ventilation device often can cause the black problem of falling of print cartridge.

Summary of the invention

For the problems referred to above, the utility model provides a kind of effective minimizing to fall the novel without the sponge ink-jet printer cartridge of black phenomenon.

The utility model is that the technical scheme that its technical problem of solution adopts is:

A kind of novel without the sponge ink-jet printer cartridge, comprise box body, ink storage chamber and nozzle, ink storage chamber is arranged in the box body, nozzle is arranged at the box body outside, ink storage chamber and nozzle are communicated with by the ink outlet port that is arranged on the box side wall, be provided with the compression cotton core in the described nozzle, be provided with and the blotting cotton that compresses cotton core and is connected in a side of ink outlet port in the box body, the blotting cotton is placed in the chamber, chamber is communicated with ink storage chamber, be provided with an air guide path on the box body, the air guide path directly is communicated with described chamber with outside atmosphere.

Preferably, described air guide path comprises the inlet chamber that is arranged on chamber one side, the air inlet duct that is arranged on the air slot at the box body back side and is arranged on the box body top, is communicated with successively between chamber, inlet chamber, air slot and the air inlet duct.

Preferably, described ink storage chamber is comprised of some discrete black chambeies that communicate, and the ink container of the circuitous bending of the discrete black chamber of part by being arranged on the box body back side is communicated with.

Preferably, the utility model comprises the protective cover that fastens with box body one side that is provided with nozzle, is provided with the counterbore that is complementary with nozzle location and profile on the protective cover.

Preferably, a side of described box body is provided with the separate type chip set.

Preferably, the top of described box body is provided with the pouring ink hole that is communicated with ink storage chamber, is provided with plug on the pouring ink hole.

The beneficial effects of the utility model are: the utility model is provided with directly so that the air guide path that the cotton chamber of living in of blotting is communicated with outside atmosphere, this air guide path guarantees that print cartridge can normal ventilation when printing, it cooperates the ink jetting structure of compression cotton core and blotting cotton can play the effect of limit ink flow, assurance print cartridge inside and outside air pressure balance, guarantee that print cartridge does not fall ink, can continue normal printing.

Description of drawings

Be further detailed below in conjunction with the drawings and specific embodiments:

Fig. 1 is decomposition texture schematic diagram of the present utility model;

Fig. 2 is the structural representation at the utility model box body back side;

Fig. 3 is the structural representation in the utility model air guide path.

The specific embodiment

Referring to figs. 1 through Fig. 3, of the present utility model a kind of novel without the sponge ink-jet printer cartridge, comprise box body 1, ink storage chamber 2 and nozzle 3, ink storage chamber 2 is arranged in the box body 1, nozzle 3 is arranged at box body 1 outside, ink storage chamber 2 and nozzle 3 are communicated with by the ink outlet port 4 that is arranged on box body 1 sidewall, be provided with compression cotton core 5 in the described nozzle 3, be provided with and the blotting cotton 6 that compresses cotton core 5 and be connected in a side of ink outlet port 4 in the box body 1, blotting cotton 6 is placed in the chamber 7, chamber 7 is communicated with ink storage chamber 2, is provided with an air guide path 8 on the box body 1, and air guide path 8 directly is communicated with described chamber 7 with outside atmosphere.During work, blotting cotton 6 draws ink from ink storage chamber 2, and the ink that blotting cotton 6 is drawn is guided on the compression cotton core 5, the passing sealing gasket for tattooing needle and be inserted in the compression cotton core 5 and draw ink for printing of printer.Being to draw on compression cotton core 5 when the utility model is out of ink, be not direct absorption, so its ink flowrate can obtain good control.
