Description
[technical field]
The present invention system refers to a kind of three-dimension type ink-jet driving circuit that is applicable to the heated chip of ink gun especially about a kind of ink-jet driving circuit.
[prior art]
Along with the fast development with the internet popularized of PC, ink-jet printer (ink jetprinter) 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 medium, for example general paper, special inkjet printing paper, photo paper and special-purpose transparency etc.
As everyone knows, the factor that influences the printing of inkjet printer quality has a lot, the composition of ink for example, ink supply mode of the selection of paper and ink cartridges or the like, yet ink cartridges is for any ink-jet printer, it is indispensable element, the printing of inkjet printer quality and the quality of ink cartridges more concerns, for pursuing more perfect quality, relevant developer has devoted considerable time and mental and physical efforts design in ink cartridges storage China ink and ink supply mode,, requirements such as cost of manufacture low, high storage black ability and high print quality simple in structure in the hope of meeting.
Inkjet technology development so far, control ink gun (printhead) disengages ink droplet to the mode of ink-jet medium can roughly be divided into piezoelectric type (micro piezo-electric type) and hot bubble type (thermal bubble type) two big classes.With the hot bubble type ink jet head is example, and its operating principle system utilizes heating resistor (ink firingresistor) heating to make the part ink produce bubble, and then ink is pushed out a plurality of jet orifice (nozzle) is sprayed onto on the ink-jet medium.
See also Fig. 1, it is the ink-jet driving circuit schematic diagram of single heating resistor running of control in the known heated chip, as shown in the figure, it is to comprise: heating resistor (ink firing resistor) 11, driving transistors (Driver MOS) 12 and two input endpoint A (Address), P (power) and one connect end points (COM) altogether, wherein heating resistor 12 1 ends are connected in the drain electrode end (Drain) of driving transistors 12, the other end is connected in input endpoint P, as for connecing source terminal (Source) and the gate terminal (Gate) that end points (COM) and input endpoint A are connected to driving transistors 12 altogether, and this connects end points (COM) altogether and is connected with earth terminal (Ground), when printer control system (not shown) desire is carried out the ink-jet action, can transmit an activation signal (Enable signal) by input endpoint A, make driving transistors (Driver MOS) 12 conductings, input endpoint P can transmit one and print voltage simultaneously, thus, the temperature of heating resistor 12 raises, and the generation bubble that the ink heating is made and then ink is sprayed onto on the inkjet printing medium.
In order to accelerate print speed, generally can increase the number of jet orifice, and with a plurality of jet orifice arrangements, see also Fig. 2, the ink-jet that is a plurality of heating resistor runnings of control in the known heated chip drives the array circuit schematic diagram, as shown in the figure, ink-jet drives array circuit system and is made up of a plurality of ink-jet driving circuit 1, wherein input endpoint A1～A4 and P1～P8 are connected in the contact of ink gun, and is connected with printer control system (not shown) by this contact, and printer control system (not shown) utilizes the jet orifice of input endpoint A1～A4 and P1～P8 selection desire ink-jet.When the jet orifice number of ink gun increases, the contact number of ink gun is increased, so be easy to generate the contact loose contact of ink gun, the reliability of contact reduces, and then influences print quality.
Therefore, how to develop a kind of ink-jet driving circuit that is applicable to ink gun that improves above-mentioned known techniques disappearance, real in pressing for the problem of solution at present.
