Abstract
The invention discloses an ink box of an ink-jet printer. The ink box of the ink-jet printer comprises a small ink supply chamber, a large ink supply chamber below the small ink supply chamber, a slideway arranged in the large ink supply chamber, a piston arranged on the slideway and matched with the slideway, and an ink jet nozzle arranged at the lower end of the large ink supply chamber, wherein an elastic film is attached to the ink jet nozzle; through holes are formed in the top and the bottom of the small ink supply chamber respectively; an air flue communicated with external air pressure is formed in the lateral side of the slideway; an elastic rubber pad is arranged on the piston; one end of the elastic rubber pad is connected with the left end of the slideway in a fastened mode; the lower end of the small ink supply chamber is further provided with a movable baffle used for abutting against the piston. Pressure in the ink box is controlled through stretching out and drawing back of the elastic rubber pad, then the supplying speed of ink can be effectively controlled, the response speed is high, and the two ink supply chambers are combined for use to enlarge the size of the ink box.
Description
Technical field
The present invention relates to a kind of print cartridge, particularly relate to a kind of cartridge of ink-jet printer.
Background technology
Ink-jet printer can be divided into solid inkjet and liquid ink jet two kinds (now more common with the latter again) by operation principle, and liquid ink jet mode can be divided into bubble type and liquid piezoelectric type.Bubbler techniques is by heated nozzle, makes ink produce bubble, be sprayed onto on print media, and the critical piece print cartridge of ink-jet printer is in print job, particularly important.At present, mainly there is following shortcoming in the print cartridge on market: print cartridge capacity is less, easy ink leak, and after long-time use, the speed that ink is out of ink and fluency all will reduce greatly, and the work for people brings a lot of inconvenience.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of cartridge of ink-jet printer, overcome little, the out of ink slow-footed defect of print cartridge capacity.
In order to achieve the above object, the present invention is by the following technical solutions:
A kind of cartridge of ink-jet printer, comprises little ink supply room, is positioned at the large ink supply room below little ink supply room, be arranged on the slideway of large ink supply indoor, be arranged on the piston that this slideway also matches with it, and be arranged on the inkjet mouth of lower end, large ink supply room, be pasted with one deck elastic membrane at this inkjet mouth; Wherein, through hole is respectively equipped with at the top of little ink supply room and bottom, the air flue communicated with ambient pressure together is then offered at the side of slideway, piston is provided with a resilient rubbber cushion, the left end of this resilient rubbber cushion one end and slideway is fastenedly connected, and is also provided with one in order to keep out the sideboard of piston in the lower end of described little ink supply room.
Further, described piston is provided with and runs through this piston together and connecting pipe in order to be communicated with little ink supply room and large ink supply room.
The invention has the beneficial effects as follows: stretching by resilient rubbber cushion, control the pressure in print cartridge, and then effectively can control the feed speed of ink, fast response time, two ink supply rooms combinationally use the volume expanding print cartridge.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: the large ink supply room of 1-, 2-slideway, 3-piston, 4-inkjet mouth, 5-resilient rubbber cushion, the little ink supply room of 6-, 7-connecting pipe, 8-sideboard, 9-elastic membrane.
Detailed description of the invention
Below by embodiment, the invention will be further described by reference to the accompanying drawings.
As shown in Figure 1, a kind of cartridge of ink-jet printer, comprise little ink supply room 6, be positioned at the large ink supply room 1 below little ink supply room 6, be arranged on the slideway 2 in large ink supply room 1, be arranged on the piston 3 that this slip 2 also matches with it, and be arranged on the inkjet mouth 4 of lower end, large ink supply room 1, in order to better realize the present embodiment, preventing ink leakage, being pasted with one deck elastic membrane 9 at this inkjet mouth 4; Wherein, be respectively equipped with through hole at the top of little ink supply room 6 and bottom, then offer the air flue communicated with ambient pressure together at the side of slideway 2, piston 3 is provided with a resilient rubbber cushion 5, and the left end of this resilient rubbber cushion 5 one end and slideway 2 is fastenedly connected.This resilient rubbber cushion 5 is moved to the left in order to pull piston 3, efficiently avoid to cause piston 3 cannot travelling backwards because pressure transformation is uneven, causes the ink supply of little ink supply room 6 to be overflowed, wasted ink.Further, one is also provided with in order to keep out the sideboard 8 of piston 3 in the lower end of described little ink supply room 6.This sideboard 8 is rectangular configuration, and it is connected with the side of large ink supply room 1 by connecting resilient rubbber cushion.
When little ink supply room 6 is identical with the ink volume in large ink supply room 1, pressure between them is equal, and when large ink supply room 1 ink supply, the ink in it reduces, pressure reduces, ambient atmosphere pressure is constant, and then promotion piston 3 moves right, and the connecting pipe 7 on piston 3 is connected with the through hole bottom little ink supply room 6, little ink supply room 6 is to large ink supply room 1 ink supply, after pressure in large ink supply room 1 increases, piston 3 is moved to the left on slideway 2, cuts off the connection between large ink supply room and little ink supply room.
Stretching by resilient rubbber cushion, control the pressure in print cartridge, and then effectively can control the feed speed of ink, fast response time, two ink supply rooms combinationally use the volume expanding print cartridge.
Claims (2)
1. a cartridge of ink-jet printer, it is characterized in that: comprise little ink supply room, be positioned at the large ink supply room below little ink supply room, be arranged on the slideway of large ink supply indoor, be arranged on the piston that this slideway also matches with it, and be arranged on the inkjet mouth of lower end, large ink supply room, be pasted with one deck elastic membrane at this inkjet mouth; Wherein, through hole is respectively equipped with at the top of little ink supply room and bottom, the air flue communicated with ambient pressure together is then offered at the side of slideway, piston is provided with a resilient rubbber cushion, the left end of this resilient rubbber cushion one end and slideway is fastenedly connected, and is also provided with one in order to keep out the sideboard of piston in the lower end of described little ink supply room.
2. a kind of cartridge of ink-jet printer according to claim 1, is characterized in that: described piston is provided with and runs through this piston together and connecting pipe in order to be communicated with little ink supply room and large ink supply room.
