Description

A kind of recovery print cartridge

Technical field

The utility model relates to the print cartridge after a kind of the recovery.

Background technology

The injection of ink droplet is controlled in the record head utilization of ink-jet printer heat or vibration, when record head print cartridge ink inside deficiency, the state of being unable to supply ink carry out sky that the ink ejection operates down when beating, can break down.Therefore, in ink-jet printer, in order not make record head empty beating being taken place, needs to monitor the ink surplus in the print cartridge.

At present, common a kind of piezoelectric transducer of internal control module and print cartridge that utilizes is worked in coordination to detect the ink-jet printer of ink surplus.Wherein, ink-jet printer stores information such as predefined print cartridge model, color, and printer has a control module, is used for the various information that the managing printing process is produced, as date printed, number of copies, ink surplus, ink droplet calculating etc.; Then be fixed with storage chip and piezoelectric transducer on the supporting with it print cartridge, wherein memory chip stores relevant initial informations such as the model of print cartridge, ink color, ink capacity, thereby control print cartridge and printer mate; And the vibration signal frequency that piezoelectric transducer is produced when having or not ink in print cartridge is different, and during if any China ink, frequency is about 33KHZ, and when inkless, frequency can be judged the ink surplus about 100KHZ.Significantly, in print procedure, all there are information exchange (as figure one) in printer and storage chip, printer and piezoelectric transducer.Simultaneously, because can there be certain error in piezoelectric transducer, usually can be or think that the residue of ink water yield is actual in the print cartridge and be that the actual quantity of ink of " sky " is stored in the storage chip as a corrected value with the error amount of piezoelectric transducer, i.e. control information.

Because printer is to move with the prerequisite that exists for of piezoelectric transducer, then when print cartridge is installed on the printer, after receiving the normal response message of print cartridge side pressure electric transducer and detecting successfully to the information of storage chip, printer can print.

In print procedure, control module in the printer can be sent to information such as the date printed that write down, ink surplus and preserve in the storage chip, and, control module can apply driving pulse to piezoelectric transducer in this process, it is vibrated, produce corresponding frequency of oscillation, being printed machine examination measures, because different frequencies of oscillation is represented quantity of ink information different in the print cartridge, when inkless, then printer just can be determined the ink surplus of print cartridge according to detected frequency of oscillation if any China ink.Send the frequency of oscillation of " ink uses up " when piezoelectric transducer, the control module of printer can read control information from storage chip, sprayable unnecessary quantity of ink and carry out this injection action when calculating reaches the true terminal point of ink, up to reaching the true terminal point of ink, this moment, printer can be pointed out user's ink surplus deficiency, needed to change print cartridge.

By the control procedure of above-mentioned ink surplus as can be known, piezoelectric transducer is the actual detected parts, it can point out " China ink will be use up ", the printer control module then is a management component, the information that piezoelectric transducer provides is analyzed, calculated to obtain the true terminal point of accurate ink, the ink residual volume is controlled to minimum.

But, there is such problem in this print cartridge: (1) pour water in the print cartridge manufacture process excessive velocities or variation of surrounding environment in transportation, all may produce too much bubble or make air bubble expansion, when bubble is adsorbed on piezoelectric transducer surperficial, this moment is if be installed in print cartridge in the printer, printer can be owing to the wrong responses information that receives from piezoelectric transducer makes a mistake the initialization process of printer, and print cartridge then can't continue to use; When (2) damaging for some reason as if the piezoelectric transducer in the print cartridge, entering the sensor container cavity as ink is short-circuited it, then this moment print cartridge is packed in the printer, printer can cause print cartridge can't continue to use owing to the wrong responses information that receives from piezoelectric transducer makes a mistake the initialization process of printer equally; (3) if in the print cartridge use because the atmosphere that enters by gas port can produce bubble and be adsorbed on the surface of piezoelectric transducer, then this moment piezoelectric transducer detection can become unstable, cause ink level to detect and make mistakes.

In addition, print cartridge is as the consumptive material of printer, and major part is dropped after using up, and the print cartridge that these abandon comprises parts such as plastics, film, rubber, chip, in the middle of major part all can not natural degradation, so not only can cause the wasting of resources, and can bring burden to environment.Along with the generally use of ink-jet printer, the consumption of print cartridge little by little increases, and is if the old print cartridge of sky is not reclaimed, then more and more serious to the pollution meeting of environment.Therefore,, reduce environmental pollution, should take to reclaim the measure of processing for resource is effectively reused.

But when reclaiming at the above-mentioned print cartridge that has storage chip and piezoelectric transducer, because described piezoelectric transducer is all had relatively high expectations to ink characteristics and filling process etc., as sensor surface bubble etc. can not be arranged, these all make the yield rate of regeneration print cartridge lower, difficult quality is stable, increases cost recovery.

The utility model content

The utility model provides a kind of recovery print cartridge, and is lower to solve existing recovery print cartridge yield rate, the unstable and high technical problem of cost recovery of quality.

In order to solve above technical problem, the technical scheme that the utility model provides is:

A kind of recovery print cartridge, comprise the ink chamber of storage ink, the supply ink enters print cartridge inside to the ink outlet port of printhead, guiding extraneous air gas port, piezoelectric transducer and storage chip, it is characterized in that, comprise that also the sensor that replaces piezoelectric transducer substitutes portion, has electric contact on the described storage chip, described sensor substitutes in the portion has the circuit of exportable original piezoelectric transducer substitution signal and the lead that is connected with described circuit, is connected with electric contact by lead between the alternative portion of described sensor and the storage chip.

After having adopted technique scheme, because sensor substitutes portion can be according to the certain substitution signal of testing conditions output of ink-jet printer output, this substitution signal is equivalent to the oscillation frequency signal that original piezoelectric transducer is exported when there is ink in print cartridge, when receiving this signal, printer is thought and is also had ink in the print cartridge and continue action, when printer repeatedly receives the stable glitch that is not inconsistent with actual quantity of ink, printer can utilize control module to carry out the management of ink surplus this moment, not influencing the user uses, print cartridge after the recovery is the yield rate height not only, steady quality, and cost recovery is low, the print cartridge yield rate that has solved after the existing recovery is lower, the unstable and high technical problem of cost recovery of quality.

The specific embodiment

A kind of recovery comprises alternative portion of sensor such as the analog sensor 2 that is used to replace original piezoelectric transducer in the print cartridge, the circuit that has the analog signal of output in the wherein said analog sensor 2, the installation response message of exportable and original piezoelectric transducer equivalence, and the analog signal of original piezoelectric transducer institute outputting oscillation signal equivalence when having ink with print cartridge, make printer can discern the existence of print cartridge and think and have ink in the print cartridge and print action.

Obtain this recovery print cartridge and need carry out following recycling step:

1. utilize syringe to take out the residual ink that reclaims in the print cartridge, the cleaning print cartridge, tool using is pulled down storage chip 1, and original piezoelectric transducer is exposed, and removes original contact on it, space around its surface of shutoff reaches, thereby this original piezoelectric transducer of forbidding;

2. analog sensor 2 is packed in the print cartridge and (can be arranged on the storage chip 1 or be arranged separately in print cartridge inside, and do not contact) with ink, the join dependency circuit, whether the circuit that is used to export analog signal in the middle of the detection can normally be exported, if cannot, analog signal then needs described interlock circuit is checked and tested, till can normally be exported;

3. storage chip 1 is reinstalled print cartridge, to described recovery print cartridge filling ink, when ink capacity reached predetermined value, print cartridge was reclaimed in sealing.

According to the ink chamber that has storage ink in the recovery print cartridge after the above-mentioned steps recovery, with the ink feed of ink chamber ink outlet port to the printhead of printer, the gas port that is communicated with extraneous air and print cartridge inside, the storage chip 1 that is used for substituting the analog sensor 2 of original piezoelectric transducer and is used to store ink information etc., wherein have an exportable circuit and a lead 4 that is connected with described circuit that is equivalent to print cartridge analog signal of the oscillator signal of original piezoelectric transducer when China ink is arranged in the analog sensor 2, having a circuit substrate on the storage chip 1 and be positioned at several electric contacts 3 on the described substrate, is to be connected as shown in Figure 3 with electric contact 3 by lead 4 between analog sensor 2 and the storage chip 1 then.Can be electrically connected with the contact of printer side owing to storage chip 1 the above several electric contact 3 simultaneously, therefore the lead 4 of analog sensor 2 can be connected with described printer side contact by described electric contact 3, thereby analog sensor 2 can communicate with printer.

Like this, in the time should reclaiming print cartridge and pack printer into, analog sensor 2 can the default analog signal that is equivalent to original piezoelectric transducer installation answer signal of output, makes printer confirm the information of print cartridge, carries out initialization process, and print cartridge is continued use.Printer can be to analog sensor 2 output testing conditions subsequently, described analog sensor 2 moves according to the condition of this appointment, the oscillator signal equivalence of when there is ink in print cartridge, being exported with original piezoelectric transducer that output is prepared analog signal, when printer interface is received the analog signal of being exported, will be as existing ink to continue its action in the print cartridge.Because printer can be carried different testing conditions to piezoelectric transducer in the compartment of terrain, but analog sensor 2 always is the analog signal of the same frequency that output is stable, the i.e. so-called glitch that is not inconsistent with actual ink remaining amount, different with signal frequency range default in the printer, then printer can judge that the sensor detection is wrong, not with this testing result as after this processing, and manage the ink surplus with control module, be that printer still can be proceeded print processing, up to reaching the ink end point values that number of times that control module operates according to the information and the printer of storage chip 1 calculates, judge the ink surplus deficiency in the print cartridge again, notify the client to change print cartridge (as figure two).Therefore, from the printer aspect, as long as analog sensor 2 is loaded on the print cartridge, just can obtain being equivalent to the response message of original piezoelectric transducer, obtain being equivalent to the analog signal of the partial vibration signal of original piezoelectric transducer, guarantee the normal use of printer, can make the resource recycling, reduce environmental pollution; And from customer-side, use and reclaim the number of print pages that print cartridge just can reach original-pack print cartridge, can reduce use cost.
