Below in conjunction with accompanying drawing the described device of the embodiment of the invention is described in detail.
Referring to Fig. 1, for the embodiment of the invention has the structure chart of the device of 4 print cartridge ink-jet printer cleaning pressures control, what magnetic valve used in the present embodiment is the two-bit triplet magnetic valve, and pressure-detecting device is a pressure sensor.The described device of present embodiment comprises print cartridge 1,2,3,4; Two-bit triplet magnetic valve 5,6,7,8,9; Pressure sensor 10; Negative pressure gas circuit port one 1; Atmosphere port 12; Positive pressure gas road port 13.Wherein print cartridge 1,2,3,4 has been formed four control branch roads with corresponding two-bit triplet magnetic valve 5,6,7,8; Article four, after the parallel connection of control branch road with two-bit triplet magnetic valve 9, pressure sensor 10, negative pressure gas circuit port one 1, atmosphere port 12, positive pressure gas road port 13 have been formed the control main road.Concrete connection is as follows:
The gas circuit mouth of print cartridge 1,2,3,4 respectively connects the public port 501,601,701,801 of a two-bit triplet magnetic valve 5,6,7,8.Normal ported 502,602,702,802 of two-bit triplet magnetic valve 5,6,7,8 connects negative pressure gas circuit port one 1.The normally closed port 503,603,703,803 of two-bit triplet magnetic valve 5,6,7,8 connects the public port 901 of two-bit triplet magnetic valve 9.Normal ported 902 of two-bit triplet magnetic valve 9 connects atmosphere port 12.The normally closed port 903 of two-bit triplet magnetic valve 9 connects positive pressure gas road port 13.The public port 901 of two-bit triplet magnetic valve 9 connects a pressure sensor 10 and is used for the detected pressures size.
The control flow chart of Fig. 2 nozzle of the shower nozzle of single print cartridge correspondence for present embodiment cleans, the shower nozzle that cleans print cartridge 1 correspondence with needs is an example, the concrete job step of present embodiment is as follows:
When in the present embodiment 1,2,3 collectives being cleaned, at first give the two-bit triplet magnetic valve on the control main road 9 energisings, give corresponding two-bit triplet magnetic valve 5,6,7 energisings of controlling on the branch road of shower nozzle of required cleaning then, malleation enters print cartridge 1 from positive pressure gas road port 13 through two-bit triplet magnetic valve 9,5; Enter print cartridge 2 through two-bit triplet magnetic valve 9,6; Enter in the print cartridge 3 through two-bit triplet magnetic valve 9,7.In the cleaning process, print cartridge 1,2,3 internal gas pressures are malleation, and ink is extruded away from print cartridge 1,2,3, clean the nozzle of the shower nozzle that links to each other with print cartridge 1,2,3.Print cartridge 4 still links to each other with negative pressure gas circuit port one 1, can not influenced by the malleation gas circuit.This moment, cleaning pressure kept a definite value, after scavenging period reaches setting value, cleaned and finished, and entered the cleaning ending phase.When the pressure in the pressure sensor 10 detected cleaning gas circuits on controlling main road was greater than last restriction equally, then cleaning process broke down, and directly enters the cleaning ending phase.Enter clean ending phase after, the two-bit triplet magnetic valve 9 on the closing control main road at first, remaining malleation is discharged in the atmosphere through two-bit triplet magnetic valve 5,9 and goes in the print cartridge 1; Remaining malleation is discharged in the atmosphere through two-bit triplet magnetic valve 6,9 and goes in the print cartridge 2; Remaining malleation is discharged in the atmosphere through two-bit triplet magnetic valve 7,9 and goes in the print cartridge 3.When pressure sensor 10 detects malleation less than lower limit, think when cleaning malleation complete obiteration in the gas circuit, corresponding two-bit triplet magnetic valve 5,6,7 outages make print cartridge 1,2,3 be connected to negative pressure road port 11 through two-bit triplet magnetic valve 5,6,7.
The device of ink-jet printer cleaning pressure that present embodiment provides control can carry out independent cleaning to the nozzle of the shower nozzle of single print cartridge correspondence, also can carry out collective to the nozzle of the shower nozzle of a plurality of print cartridge correspondences simultaneously and clean.In the process that single-nozzle is cleaned, this device only need be controlled two two-bit triplet magnetic valves in the present embodiment, greatly reduces the complexity of control.Because in cleaning process, do not need the print cartridge of the nozzle correspondence of cleaning still to connect negative pressure gas circuit port, can not cause ink in print cartridge, to flow out voluntarily, cause damage, therefore improved the reliability of device.Because pressure sensor detects the positive air pressure value of cleaning in the gas circuit all the time, and the two-bit triplet magnetic valve normal ported connection atmosphere port under off-position on the control main road, the security of device has also obtained effective assurance.
What magnetic valve used in the embodiment of the invention is the two-bit triplet magnetic valve, but be not limited only to the magnetic valve of this type, the multidigit various way solenoid valve of other types, for example two position four-way solenoid valves, two five-way electromagnetic valves, 3 position-5 way magnetic valve etc. also can be used for the embodiment of the invention.
The foregoing description has been described the control method that the ink-jet printer of 4 print cartridges cleaning pressure is arranged, and this method is equally applicable to comprise the control of the ink-jet printer cleaning pressure of any a plurality of print cartridges.
In sum, the embodiment of the invention provides a kind of device of ink-jet printer gas circuit control, comprises some print cartridges, some magnetic valves, negative pressure road port, positive air pressure road port, atmosphere port; The gas circuit mouth of described each print cartridge connects first port of a magnetic valve; Be connected on the negative pressure road port after second port parallel connection of described each magnetic valve, be connected to first port on another one and the magnetic valve that positive air pressure is connected after the 3rd port parallel connection; Second port of the magnetic valve that described another one is connected with positive air pressure is connected to the positive air pressure road port, and the 3rd port is connected to the atmosphere port.So only need switch the gas circuit port of the gas circuit mouth connection of print cartridge, when the nozzle to single shower nozzle carries out the independence cleaning, only need two magnetic valves of control, the complexity that reduction is controlled the ink-jet printer cleaning pressure according to the duty of two magnetic valves.Because in cleaning process, do not need the print cartridge of the nozzle correspondence of cleaning still to connect negative pressure gas circuit port, can not cause ink in print cartridge, to flow out voluntarily, cause damage, therefore improved the reliability of device.Because pressure sensor detects the positive air pressure value of cleaning in the gas circuit all the time, the security of device has also obtained effective assurance.
Though described the present invention by embodiment, those of ordinary skills know, without departing from the spirit and substance in the present invention, just can make the present invention that many distortion and variation are arranged, and scope of the present invention is limited to the appended claims.
