Abstract
The invention relates to an ink jet control circuit. A heating chip disposed inside an ink-jetting head structure comprises a heater and six switch circuits and receives a power signal, a printing data signal, a preheating data signal, a heating control signal, and a preheating control signal. When the printing data signal and the heating control signal are maintained at high potential, the heater heats a part of ink and generates bubbles such that the ink is pushed out of the ink-jetting holes on the heating chip. When the preheating control signal and the preheating data signal are maintained at high potential, the heater preheats a part of the ink and the ink-jetting head. Therefore, the ink-jetting head has easily-controlled preheating temperature and high preheating efficiency.
Description
Technical field
The present invention is about a kind of ink-jet controlling circuit, espespecially a kind of ink-jet controlling circuit that is applicable to the heating chip of ink gun.
Background technology
Along with the fast development of the universal and world-wide web of PC, ink-jet printer has become very general peripheral equipment, is widely used in family, personal work chamber or even all trades and professions in recent years.The major advantage of ink-jet printer is cheap, the low and good print quality of when operation noise, and printable in various media, such as general paper, special inkjet printing paper, photo paper and special-purpose transparency etc.
Affecting printing of inkjet printer product qualitative factor has a lot, for example ink forms, paper is selected and ink cartridges ink supply mode etc., yet ink cartridges is for any ink-jet printer, is indispensable element, the print quality of ink-jet printer and the quality of ink cartridges more concerns.For pursuing more perfect quality, relevant developer has devoted considerable time and has designed in ink cartridges ink storage and ink supply mode with mental and physical efforts, and the phase can meet the requirements such as simple in structure, cost of manufacture is low, high ink storage ability and high print quality.
Inkjet technology is developed so far, and controls ink gun and disengages ink droplet to the mode of ink-jet media and can roughly be divided into piezoelectric type and the large class of hot bubble type two.Take hot bubble type ink jet head as example, and its operating principle system utilizes heating resistor heating to make part ink produce bubble, and then ink is injected on ink-jet media.
Refer to Fig. 1, it is the ink-jet driving circuit schematic diagram of controlling single heating resistor running in known heating chip, as shown in the figure, its ink-jet driving circuit 1 is to comprise: heating resistor 11,12 and two input endpoint D(Print-Data of driving transistors (Driver MOS)), P(Power) and one connect altogether end points (COM), wherein heating resistor 11 one end are connected in the drain electrode end (Drain) of driving transistors 12, and the other end is connected in input endpoint P.As for meeting altogether end points COM and input endpoint D, system is connected to source terminal (Source) and the gate terminal (Gate) of driving transistors 12, and this meets altogether end points COM and is connected with earth terminal, when printer control system (not shown) wish is carried out ink-jet action, can transmit an enable signal (Enable Signal) by input endpoint D, control driving transistors 12 conductings, input endpoint P can transmit a printing voltage to heating resistor 11 simultaneously, thus, the temperature of heating resistor 11 will raise, and then ink is heated to produce bubble, ink is sprayed onto on ink-jet media.
Yet known ink-jet driving circuit is in response to ever-increasing ink jet ink head ink-jet hole count problem, its control mode is transformed into sequence transmission by traditional two dimension control and controls, its benefit is significantly to reduce contact point (Pad) number of controlling chip of ink-jet head, and can accelerate print speed.The printing voltage that generally input endpoint D can be transmitted is divided into two kinds of preheat pulse voltage (Warming Pulse) and heat pulse voltages (Firing Pulse), main heating resistor 11 heating that first utilize preheat pulse Control of Voltage ink-jet driving circuit, and then make part ink and ink gun be heated to a specified temp, then again by heating resistor 11 heating of heat pulse Control of Voltage ink-jet driving circuit, 11 pairs of part inks of heating resistor are heated and produce bubble and then a jet orifice of ink being pushed out to this heating chip.
Refer to Fig. 2, it is the oscillogram of voltage and the heating resistor both end voltage Vr of known input endpoint P, D, and as shown in the figure, time ta1 is high potential to input endpoint D between ta2, indicates the printing of printed information wish.Now, printer control system is carried out ink-jet action, and transmit respectively a preheat pulse voltage P1 and a heat pulse voltage P2 in input endpoint P, by preheat pulse voltage P1 first by part ink and ink gun preheating, recycling heat pulse voltage P2 is the heating of part ink, makes it to produce bubble and ink is sprayed onto on corresponding ink-jet media.Therefore the both end voltage Vr that, preheat pulse voltage P1 and heat pulse voltage P2 can make heating resistor 11 at time ta1 to producing respectively two high potentials between ta2; Yet, time ta3 between ta4 because input endpoint D is electronegative potential, do not have printed information wish to print, therefore second preheat pulse voltage P1 that input endpoint P transmits, second heat pulse voltage P2, be time tp5 to tp6 and tp7 to carrying out preheating to part ink and ink gun between tp8, the both end voltage Vr that makes heating resistor 11 at time ta3 to be maintained electronegative potential between ta4 always.
In well known single ink gun, there is a plurality of jet orifice and ink-jet driving circuit, known technology only just can carry out preheating to part ink and ink gun by the ink-jet driving circuit that carries out the printing of row data, when therefore if printed information is few, the ink-jet driving circuit number that preheating is carried out in relative meeting just tails off, because the temperature of ink gun is whole rather than only for single jet orifice, therefore the heat that only minority jet orifice is carried out preheating will soon be taken away by whole heating chip, so will cause ink gun preheat temperature not enough, and then affect print quality.
Therefore, how to develop a kind of ink-jet controlling circuit that improves above-mentioned known technology disappearance, real is current problem in the urgent need to address.
Summary of the invention
Main purpose of the present invention is to provide a kind of ink-jet controlling circuit, it is by when printed information signal and heating control signal are while being high potential signal, heater is heated part ink and produce bubble and then this jet orifice of ink being pushed out to this heating chip; Otherwise when printed information signal is that low-potential signal and warm-up control signal and preheating data signal are while being high potential signal, control heater carries out preheating to part ink and this ink gun, its ink gun preheat temperature is easily controlled and pre-thermal efficiency raising, in order to do solving known technology, only the ink-jet driving circuit that carries out the printing of row data just can carried out to preheating to part ink and ink gun, cause ink gun preheat temperature not enough, and then affect the shortcomings such as print quality.
Another object of the present invention is to provide a kind of ink-jet controlling circuit, in the same time, only have the heater that preheating data signal An-1 controls can carry out preheating, can avoid causing the problem of the excessive and chip overheating of power consumption; And when the An time prints, can carry out preheating in the time of An-1, before printing in the An time, carry out preheating, and reach the ink-jet effect before ink-jet.Even therefore when not printing, receive the also preheating really of warm-up control signal and preheating data signal, reach the effect that keeps chip temperature, and then guarantee print quality, and the lifting of ink gun preheat temperature control efficiency also can reach the effect that print speed is improved.
