Description
Technical field
The utility model relates to a kind of print cartridge, specifically, is a kind of ink-jet printer China ink amount control system.
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 is to overcome little, the out of ink slow-footed defective of print cartridge capacity in the prior art, 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:
Ink-jet printer China ink amount control system 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, the piston that is arranged on this slideway and is complementary with it, and the inkjet mouth that is arranged on lower end, main supply China ink chamber; Wherein, be provided with the dividing plate that is provided with together check valve in the middle of the described auxiliary ink supply chamber, this dividing plate will assist the ink supply chamber to be divided into ink supply for subsequent use chamber and secondary ink supply chamber, top and bottom in secondary ink supply chamber are respectively equipped with through hole, side at slideway then offers the slit that communicates with ambient pressure together, also be provided with one in order to keep out the active block stop of piston in the lower end of described secondary ink supply chamber, on described piston, also be provided with a spring, the side of one end of this spring and secondary ink supply chamber is fastenedly connected, and is pasted with one deck sponge at inkjet mouth.
Further, described ink supply for subsequent use chamber and secondary ink supply chamber area equate.
Further, described piston is made by polyethylene.
Run through together this piston and in order to be communicated with the ink-feed channel of the black chamber of secondary ink supply chamber and main supply in order better to realize that the utility model, described piston are provided with.
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 three grades of ink supply chambers, wherein, secondary 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, secondary ink supply chamber, secondary 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 secondary 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 secondary 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) thus just be traditional common material in the utility model, not only cheap, and make very conveniently, established favourable basis for it promotes the use on a large scale.
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, 2-slideway, 3-piston, 4-inkjet mouth, 5-ink supply for subsequent use chamber, 6-level ink supply chamber, 7-ink-feed channel, 8-active block stop, 9-spring, 10-sponge, 11-check valve.
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, ink-jet printer China ink amount control system comprises auxiliary ink supply chamber, be positioned at the main supply China ink chamber 1 of below, auxiliary ink supply chamber, be arranged on the slideway 2 in the main supply China ink chamber 1, the piston 3 that is arranged on this slideway 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 provided with the dividing plate that is provided with together check valve 11 in the middle of the described auxiliary ink supply chamber, this dividing plate will assist the ink supply chamber to be divided into ink supply for subsequent use chamber 5 and secondary ink supply chamber 6, check valve 11 only allows ink to flow to secondary ink supply chamber 6 from ink supply for subsequent use chamber 5, top and bottom in secondary ink supply chamber 6 are respectively equipped with through hole, then offer the slit that communicates with ambient pressure together at the side of slideway 2.And described piston 3 is provided with and runs through together this piston 3 and in order to be communicated with the ink-feed channel 7 of secondary ink supply chamber 6 and main supply China ink chamber 1, also be provided with an active block stop 8 in order to keep out piston 3 in the lower end of described secondary 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.On the other hand, on described piston 3, also be provided with a spring 9, the side of one end of this spring 9 and secondary ink supply chamber 6 is fastenedly connected, this spring 9 is moved to the left in order to spur piston 3, effectively avoided causing because pressure transformation is uneven the piston can't travelling backwards, cause 6 ink supply of secondary ink supply chamber to overflow wasted ink.And, being pasted with one deck sponge 10 at inkjet mouth 4, this sponge 10 can prevent effectively that ink is from inkjet mouth 4 leakages.
When the ink volume in secondary ink supply chamber 6 and the main supply China ink chamber 1 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, secondary ink supply chamber, secondary 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 secondary 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, for the need of better finishing ink supply to, described ink supply for subsequent use chamber 5 and secondary ink supply chamber 6 areas equate.
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.
