It can also be reduced by way of reducing pump power by way of increasing pump power come increased pumping ink dynamics
The dynamics of pumping ink.The duration of a preceding pumping ink is longer in pumping ink cleaning process, and the waste ink of suction is also more, such case
Pumping ink power can suitably be reduced when a pumping ink after lower excessively causes spray head to damage in order to avoid aspirating.Such as in a complete spray
Head pumping ink cleaning process in using pumping ink three times cleaning by the way of, for the first time, for the second time and third time pumping ink pump power
It is different from.
S3, the control signal that control pump pumping ink is obtained according to the changing rule of the power of the pump；

As a kind of preferred embodiment, the control signal that the control pump power supply switches on and off is pulse signal,
In step s 4 according to the duty ratio of the power changing rule control wave of pump.
Pulse signal in the present embodiment is the action time extremely short voltage or current signal in moment suddenly change.Arteries and veins
Rushing signal is a kind of discrete signal, and shape is varied, compared with general analogue signal (such as sine wave), in the time between waveform
Axis discontinuous (having apparent interval between waveform and waveform) but to have certain periodicity be its feature.The most common pulse
Wave is rectangular wave (namely square wave).Pulse signal shows on plane coordinates to be exactly the curve for having countless breakpoints, also
It is to say to be not present in the limit of periodically some place points, such as sawtooth wave also has the letter for the digital circuit used in computer
Number, 0,1.Pulse signal, that is, the signal as beat pulse, relative to direct current, interrupted signal.The present embodiment is being patrolled
Collecting the upper pulse way of output for supporting pump can be constant pressure set time power supply, pulse control mode.Constant pressure set time electricity

Sequencing successively successively decreases.
When most starting pumping ink, the waste ink impurity in spray head is more, and the stopping state of spray head starts to take out than more serious just
Biggish pumping ink dynamics can be used when black, rapidly to pump out the waste ink impurity etc. in spray head.By preceding primary pumping
The stopping state of Mo Hou, spray head are mitigated, and pumping ink dynamics at this moment can be suitably reduced, in case suction excessively causes spray head to damage.
Therefore the pumping ink power of the pumping ink number first carried out in the present embodiment is larger, to be aspirated to spray head using biggish dynamics,
To fast powerful the waste ink in spray head is extracted out.After previous suction operation, spray head stopping state gradually improves,
It is gradually reduced the dynamics of suction, in the number of subsequent pumping ink how to realize and keep away while pumping out waste ink from spray head
Exempt to damage spray head.Such as in certain pumping ink cleaning process by the way of the cleaning of pumping ink three times, wherein taking out for the first time
Ink uses 100% pump power, and second of pumping ink uses 50% pump power, and third time pumping ink uses 30% pump function
Rate.

More, the dredging situation of spray head is preferable after pumping ink, and the power of pump at this moment can be suitably reduced in pumping ink next time, makes pumping ink
Dynamics matches with the case where current spray head.If the time of an opposite preceding pumping ink is shorter, there is also certain for spray head after pumping ink
The blocking of degree, the power of pump when at this moment can suitably increase pumping ink next time, to increase the effect of pumping ink.For example, by using
The cleaning way of pumping ink twice, if pumping ink time first time is 1000ms, pumping ink power is 100% pump power, then second
Secondary pumping ink power can be set to 30% pump power, if pumping ink time first time non-800ms, pumping ink power is 100% ink
Pump power, then second of pumping ink power can be set to 50% pump power.
