Description
Technical field
The present invention relates to the printing field, especially a kind of junction block for ink-jet printer, the print cartridge that the ink-jet printer of this junction block is installed and is used for this printer.
Background technology
Ink-jet printer is a kind of common PRN device, for modern office provides great convenience.Existing ink-jet printer uses the print cartridge that accommodates ink to spray ink as consumable container to paper, to form literal or the pattern that needs printing at paper.
Referring to Fig. 1, existing a kind of color inkjet printer has housing 11, and ink-jet printer shown in Figure 1 has omitted loam cake and the supporting plate of housing 11.Be provided with the body 12 of ink-jet printer in the housing 11, and be provided with a slide bar 13, print word car 15 and under the drive of motor (invisible among Fig. 1), move back and forth along slide bar 13.
Print on the word car 15 four print cartridges 16 removably are installed, each print cartridge 16 has housing, housing surrounds the cavity that holds ink, outer wall at each print cartridge 16 is equipped with chip piece (invisible among Fig. 1), chip is provided with memory, be used for the relevant information of storage and print cartridge 16, these information comprise print cartridge 16 model, hold the color of ink and the interior ink surplus of print cartridge etc.Also be provided with piezoelectric transducer in the cavity of print cartridge 16, for generation of piezoelectric signal and be sent to ink-jet printer.When ink-jet printer did not receive the piezoelectric signal of any one print cartridge 16, namely thinking had print cartridge 16 to install not in place and quit work.
And, because when in the cavity sufficient ink being arranged, the vibration frequency of piezoelectric transducer is lower, during the interior ink cartridge low of cavity, the vibration frequency of piezoelectric transducer is higher, so the piezoelectric signal that ink-jet printer transmits according to the piezoelectric transducer that receives judges whether sufficient ink is arranged in the print cartridge 16.
Print in the word car 15 and be provided with switching circuit board, switching circuit board is provided with a plurality of electric contacts, and switching circuit board carries out exchanges data by winding displacement 14 and main control board in the body 12, is provided with in the main control board for the communication module that carries out communication with chip.Also be provided with a plurality of electric contacts on the chip of print cartridge 16, print cartridge 16 be installed to print word car 15 after, the electric contact of chip is electrically connected with electric contact on the switching circuit board, and carries out communication by the communication module of winding displacement 14 and ink-jet printer.
Store the information of ink surplus in the chip, to read the ink balance information that is stored in the chip during ink-jet printer work, and the quantity of ink that the calculating print cartridge consumes in print procedure, after the one or many printing is complete, the ink surplus data of reading are deducted the current residual ink amount of the quantity of ink calculating print cartridge of print cartridge consumption, and the quantity of ink data after will calculating write back chip, and chip is upgraded the data of ink surplus.Before ink-jet printer is carried out printing, judge at first whether the ink surplus data of storing in the chip are zero, and judge whether the piezoelectric signal vibration frequency that piezoelectric transducer transmits is higher, if the ink surplus data of chip-stored are that the vibration frequency of zero or piezoelectric signal is higher, the ink surplus is not enough in the expression print cartridge, and ink-jet printer stops to carry out printing.
Ink-jet printer when work, need to read data that chip stores with judge whether the print cartridge model of being installed correct, whether the ink surplus sufficient etc.Like this, the manufacturer of print cartridge must spend higher cost to the chip of the equipped correspondence of each print cartridge, and this causes the production cost of print cartridge high.
Therefore, notification number is the method for modifying that the Chinese invention patent application of CN102009530A discloses a kind of imaging device and imaging device, as shown in Figure 2, this imaging device is an ink-jet printer, and this method of modifying is to repack aforesaid ink-jet printer into this application disclosed ink-jet printer.This ink-jet printer also is provided with an external junction block 20, and junction block 20 can be arranged at the housing place of ink-jet printer, namely away from printing the 15 ground settings of word car.
Referring to Fig. 3, chip 28 is electrically connected with the main control board 18 of ink-jet printer by winding displacement 25.Be provided with piezoelectric signal in the junction block 20 and produce circuit, it comprises the piezoelectric transducer 29 that is electrically connected with main control board 18, and piezoelectric transducer 29 produces the lower piezoelectric signal of frequency when being subjected to electricity, to satisfy the need of work of ink-jet printer.
Certainly, also be provided with other three chip blocks and three piezoelectric transducers, reset switch in the junction block 20, its connected mode is identical with the connected mode of chip 28, piezoelectric transducer 29 and reset switch 22, omits among Fig. 3.
When the user also opens ink-jet printer first after ink-jet printer is reequiped, if the user fails in time to install print cartridge, ink-jet printer is namely started working because receiving piezoelectric signal, and the operation of printhead is cleaned in execution, can suck the moisture retention liquid that presets in the printhead in the useless ink reservoir this moment, causes printhead to cause passage withered because there being air to enter.After print cartridge is installed to printing word car, do not have the existence of diversion successfully the ink in the print cartridge not to be sucked ink nozzle in the passage because of printhead, affect the fluency of ink supply, occur the situation of disconnected China ink when causing printing, informal voucher occurs at the paper of printing, affect print quality.
Summary of the invention
Main purpose of the present invention provides in the situation that print cartridge is not installed when a kind of ink-jet printer after avoiding reequiping is started shooting first and carries out the junction block that cleans print head operation.
