Description
Technical field
The utility model relates to a kind of print cartridge, specifically, is a kind of multistage filled ink device.
Background technology
Ink-jet printer can be divided into solid inkjet and two kinds of liquid ink-jets (now more common with the latter again) by operation principle, and the liquid ink-jetting style can be divided into bubble type (canon and hp) and liquid piezoelectric type (epson).Bubble technology (bubble jet) is by heated nozzle, makes ink produce bubble, be sprayed onto on the print media, and the critical piece print cartridge of ink-jet printer is particularly important in print job.At present, mainly there is following shortcoming in the print cartridge on the market: the print cartridge capacity is less, and easy ink leak, and after long-time the use, the speed that ink is out of ink and fluency all will reduce greatly is for people's work brings a lot of inconvenience.
The utility model content
The purpose of this utility model be to overcome in the prior art print cartridge capacity little, go out to grind slow-footed defective, provide a kind of simple in structure, realize easily print cartridge.
To achieve these goals, the scheme of the utility model employing is as follows:
Multistage filled ink device comprises auxiliary ink supply chamber, is positioned at the main supply China ink chamber of below, auxiliary ink supply chamber, is arranged on the indoor slideway of main supply China ink, is arranged on the piston that this slip is upper and be complementary with it, and the inkjet mouth that is arranged on lower end, main supply China ink chamber; Wherein, top and bottom in auxiliary ink supply chamber are respectively equipped with through hole, side at slideway then offers the slit that communicates with ambient pressure together, be provided with a spring at piston, the left end of this spring one end and slideway is fastenedly connected, and also is provided with one in order to keep out the active block stop of piston in the lower end of described auxiliary ink supply chamber.
Further, described piston is made by polyethylene.
Further, described piston is provided with and runs through together this piston and in order to be communicated with the ink-feed channel of auxiliary ink supply chamber and the black chamber of main supply.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model is not only simple in structure, and with low cost, realization convenience;
(2) the utility model is comprised of two-stage ink supply chamber, wherein, auxiliary ink supply chamber all communicates with ambient atmosphere with main supply China ink chamber, when the two ink volume is identical, pressure between them equates, when the chamber ink supply of main supply China ink, ink in it reduces, and pressure reduces, and ambient atmosphere pressure is constant, and then pushing piston moves right, so that the ink-feed channel on the piston links to each other with the through hole of bottom, auxiliary ink supply chamber, auxiliary ink supply chamber is to the chamber ink supply of main supply China ink, after the indoor pressure of main supply China ink increases, piston is moved to the left sliding into, cut off being connected between main supply China ink chamber and the auxiliary ink supply chamber, can effectively control the supply of ink by the variation of air pressure, and response speed is very fast, solved the slow problem of ink supply in the prior art, and multistage ink supply chamber has increased the volume of print cartridge widely;
(3) the utility model also is provided with one in order to keep out the active block stop of piston in the bottom of auxiliary ink supply chamber, and this active block stop has been avoided causing piston to skid off the defective of slideway because pressure change is excessive effectively;
(4) the utility model medi-spring is moved to the left in order to spur piston, has effectively avoided causing because pressure transformation is uneven the piston can't travelling backwards, causes auxiliary ink supply chamber ink supply to overflow wasted ink.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, the parts name that Reference numeral is corresponding is called: 1-main supply China ink chamber, and the 2-slideway, the 3-piston, the 4-inkjet mouth, the 5-spring, 6-assists ink supply chamber, 7-ink-feed channel, 8-active block stop.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment
As shown in Figure 1, multistage filled ink device comprises auxiliary ink supply chamber 6, be positioned at the main supply China ink chamber 1 of auxiliary 6 belows, ink supply chamber, be arranged on the slideway 2 in the main supply China ink chamber 1, the piston 3 that is arranged in this slip 2 and is complementary with it, and the inkjet mouth 4 that is arranged on 1 lower end, main supply China ink chamber; Wherein, be respectively equipped with through hole in top and the bottom of auxiliary ink supply chamber 6, then offer the slit that communicates with ambient pressure together at the side of slideway 2, be provided with a spring 5 at piston 3, the left end of these spring 5 one ends and slideway 2 is fastenedly connected.This spring 5 is moved to the left in order to spur piston 3, has effectively avoided causing because pressure transformation is uneven the piston 3 can't travelling backwards, causes auxiliary ink supply chamber 6 ink supply to overflow wasted ink.Further, also be provided with an active block stop 8 in order to keep out piston 3 in the lower end of described auxiliary ink supply chamber 6.This active block stop 8 is rectangular configuration, and it is connected by the side of linking springs with main supply China ink chamber 1.
When the ink volume in assisting the black chamber 1 of ink supply chamber 6 and main supply is identical, pressure between them equates, when chamber 1 ink supply of main supply China ink, ink in it reduces, pressure reduces, ambient atmosphere pressure is constant, and then pushing piston 3 moves right, so that the ink-feed channel 7 on the piston 3 links to each other with the through hole of 6 bottoms, auxiliary ink supply chamber, auxiliary ink supply chamber 6 is to chamber 1 ink supply of main supply China ink, after main supply China ink chamber 1 interior pressure increased, piston 3 was moved to the left at slideway 2, cut off being connected between main supply China ink chamber and the auxiliary ink supply chamber, can effectively control the supply of ink by the variation of air pressure, and response speed is very fast, solved the slow problem of ink supply in the prior art, and multistage ink supply chamber has increased the volume of print cartridge widely.
In the present embodiment, in order to prevent causing piston to skid off slideway because pressure change is excessive, also be provided with one in order to keep out the salient angle of piston 3 in the lower end of described auxiliary ink supply chamber 6.
In the present embodiment, for fear of piston absorption ink, the waste resource, described piston 3 is made by polyethylene.
According to above-described embodiment, can well realize the utility model.
