Description
Technical field
The utility model relates to a kind of print cartridge, and the print cartridge of chip especially is installed.
Background technology
Ink-jet printer is a kind of common PRN device, existing ink-jet printer uses removably print cartridge mostly, and it is installed on the ink-jet printer main body, provides printing ink to ink-jet printer, printing ink is printed nozzle ejection in the machine to recording medium, finally forms print pattern.
The print cartridge that various ink-jet printers use all has a chip that is used to store the ink relevant information mostly, and this chip generally is fixed on position corresponding with the printer probe on the print cartridge outer surface.The printer probe is generally seven or nine, has on the chip and the corresponding contact of printer number of probes and position, forms correspondingly between the two during work to be electrically connected.
When print cartridge is installed on the printer or printer when starting shooting again, the control assembly of printer all will be carried out a print cartridge identification, promptly ink box chip is discerned.The control assembly of printer can send a series of reading instruction and read information in the ink box chip, as information such as sequence number, residual ink amount, the date of production.When in information that ink box chip is replied and the printer storage during canned data coupling, then identifying end, printer can enter normal print state, otherwise printer will be pointed out mistake.
General chip all is directly to be fixed on the print cartridge outer surface by welding, non-removable connected mode such as bonding, and when the ink in the print cartridge was used up, the ink volume capacity information in the chip was recorded as " sky " or " zero ", and print cartridge and chip all go out of use together.In fact, chip can continue to use by rewriteeing, for example, more existing chips are realized its function with microprocessor (MCU), and MCU has computing, processing capacity, so, can allow the data of capacity region of MCU record be reduced to " expiring " by the setting of program by " sky ", make chip to recycle.
In order to save the use cost of print cartridge, the serve as reasons cartridge mount that chip is installed and the black cavity that is removably mounted on the cartridge mount of some print cartridge structural designs formed.When ink is used up, do not need to change chip and cartridge mount, the black cavity that only need more renew, and by the setting of program chip is rewritten, just can proceed printing.
But, there are some printers to be provided with and are used to detect a pair of probe whether print cartridge is in place, be used for chip on a pair of short-circuit contact contact accordingly and be connected, be communicated with by a short-circuit block between this a pair of short-circuit contact, so, when print cartridge is installed, this a pair of probe and the corresponding one by one contact of this a pair of short-circuit contact, this a pair of probe is a short-circuit condition; When print cartridge when printer disassembles, this a pair of probe does not contact with this a pair of short-circuit contact, this a pair of probe is an open-circuit condition.When changing print cartridge, the connection status that printer is accepted must be that this a pair of probe transfers open circuit to by short circuit, transfers short circuit again to.If be short-circuit condition always, then can't use new black cavity.The a pair of short-circuit contact of on the chip this only is to be used for contacting with this a pair of probe, makes by short-circuit block to be short-circuit condition between this a pair of probe.
So, on chip or chip pad, add a press button, short-circuit block on the press button control chip is communicated with or disconnects this a pair of short-circuit contact, thereby be used to control the state of short circuit between a pair of probe of printer or open circuit, when more renewing black cavity, pass through pushbutton switch, make between this a pair of probe and transfer open circuit to by short circuit, transfer short circuit again to, make behind the new black cavity of installation, can normally print.But, press button can take certain space, makes the volume of black cavity diminish, and the operation of press button is also inconvenient.
Summary of the invention
The purpose of this utility model provides a kind of use cost print cartridge low, easy to use.
For realizing above-mentioned main purpose, the print cartridge that the utility model provides comprises black cavity, and black cavity is provided with an ink outlet port; Chip body, chip body comprise chip connecting plate and chip body, and a plurality of chip contacts that are used for being electrically connected with printer of chip body are arranged on the chip connecting plate, and chip contacts comprises a pair of short-circuit contact; Base, base have a black cavity installation position and a chip body installation position; Be used for the short-circuit block with a pair of short-circuit contact electric connection, short-circuit block is fixed on black housing surface.
By such scheme as seen, print cartridge is installed on the ink-jet printer, when ink is used up, black cavity can be disassembled from the black cavity of base and more renew print cartridge, chip is installed on the ink-jet printer to rewrite by setting program and can continues to use.And, short-circuit block is fixed on the black cavity, when black cavity is changed, two short-circuit block contacts of short-circuit block transfer disconnection with the status of electrically connecting between a pair of short-circuit contact to by being communicated with, transfer connection again to, thereby the status of electrically connecting of the probe of ink-jet printer and this a pair of short-circuit contact is to transfer open circuit to by short circuit, transfers short circuit again to, can solve the problem that obstacle is run into of printing, normally carry out thereby guarantee to print.
As a kind of preferred scheme, short-circuit block is the short-circuit block of being made by pcb board, copper sheet, connection pin or conductive rubber.Pcb board, copper sheet, connection pin or conductive rubber are conductive material, can satisfy the connection of circuit.
As a kind of improvement of such scheme, short-circuit block is provided with two short-circuit block contacts.Contact with short-circuit contact on the chip by the short-circuit block contact, connect reliable.
As a kind of preferred scheme, the short-circuit block contact is two projectioies that are arranged on the short-circuit block surface.。Use projection, can contact with short-circuit contact easily.
Further scheme, chip connecting plate are provided with a pair of pair of contact of passing plate back connection in front.The structure that is communicated with before and after chip contacts is set to makes the pair of contact of chip connecting plate one side be connected with the contact of printer word car, and the contact of chip connecting plate opposite side is communicated with short-circuit block, thereby realizes printer word car short-circuit condition.
Scheme further, China ink cavity installation position and chip body installation position lay respectively at the both sides of base side wall, have a connected entrance between China ink cavity installation position and the chip body installation position, two short-circuit block contacts directly contact electric connection with a pair of short-circuit contact in the connected entrance position respectively.During use, when black cavity when base disassembles, short-circuit block promptly disconnects with short-circuit contact, when black cavity was installed on the base, short-circuit block promptly was communicated with short-circuit contact.This reasonable in design, cost is low, and is easy to use.
