[control system]
The control system of irritating device for ink comprises microcontroller, microswitch group and start button.Microcontroller can be single-chip microcomputer or DSP devices such as (digital signal processors).Referring to Figure 17, Figure 17 has reflected the 89C52 type single-chip microcomputer of present embodiment and the circuit diagram of peripheral circuit thereof, and the I/O mouth is used to receive the information and the operation of control filling China ink of user's input.Wherein, 8 of pin P1 group with 4 of pin P3 group totally 12 I/O mouth be used to receive the feedback levels signal of microswitch group as detecting a mouthful input.8 of pin P0 group with 7 of pin P2 group totally 15 I/O mouths are user interface input/output ports, pin P2.0 is electrically connected with start button.Pin P3.2 and pin P3.3 control the work of vavuum pump and relief valve as the delivery outlet of control system control filling China ink through the switching manipulation of triode.
Be provided with print cartridge identification module, vavuum pump control module and relief valve control module and surplus black judge module in the single-chip microcomputer 1940.The print cartridge identification module is used to receive the level signal that microswitch feeds back, and judging the toner cartridge type of being installed in each kerve according to level signal is black print cartridge or colour ink box, and then calculates the number of black print cartridge and colour ink box respectively; The vavuum pump control module is used to control the operation of vavuum pump; The relief valve control module is used to control the operation of relief valve.Surplus black judge module is used for amount of ink remaining in each ink tank is calculated, and sends signal when quantity of ink is not enough in judging ink tank.
According to the print cartridge identification module exported about the type of the print cartridge that identifies and the identification signal of number; Vavuum pump control module control vavuum pump carries out the negative pressure of taking out of first scheduled duration, and relief valve control module control relief valve carries out the pressure release of second scheduled duration.
In the present embodiment, the required design of pressure that reaches is 36KPA to print cartridge after the negative pressure through taking out.In order to set out second scheduled duration with enough durations; Suppose the print cartridge that its heap(ed) capacity that can hold all is installed in all kerves; Thereby; When relief valve is started working, the extraneous standard atmospheric pressure value 101KPA when each print cartridge pressure inside value will progressively be risen to air pressure in the gas holding portion with corresponding ink tank and reached balance mutually by force value 36KPA, therefore; Reach the lasting time of opening of relief valve in the 101KPA process through calculating print cartridge pressure inside value by 36KPA, can calculate second scheduled duration of relief valve pressure release.In the present embodiment; The print cartridge no matter the print cartridge identification module identifies is how many which kind of type and numbers be; Be stored in the second scheduled duration data that are used to control relief valve operation duration in the relief valve control module and all be set at 8 seconds; And microcontroller is transferred the operation duration of these second scheduled duration data with the control relief valve.
The vavuum pump control module is determined first scheduled duration according to the received identification signal from the print cartridge identification module through computing, thereby the control vavuum pump carries out the operation of first scheduled duration.
In the present embodiment, because the volume of the big or small capacity ink box of black or colour is more or less the same, thereby less to taking out the required influence consuming time of negative pressure, therefore, the vavuum pump control module does not determine discretely first scheduled duration according to the size of print cartridge capacity.
At the colour ink box that supposition print cartridge identification module is identified all is that volume is under the situation of colored big capacity ink box of 17ml; If what the print cartridge identification module identified is a colour ink box; Make a force value in the colour ink box reach the first required scheduled duration of 36KPA in order to set out vavuum pump; Suppose further that then colour ink box and the ink tank that is connected with colour ink box are complete empty; Be the air that is full of 17ml and 100ml volume in colour ink box and the ink tank respectively, and first pipeline and the 3rd ducted volume of air summation that are communicated with the ink supply pipeline of this complete empty colour ink box and this complete empty ink tank and are communicated with vavuum pump and this complete empty ink tank be 3ml, therefore; Comprise that the volume of air summation in the space of complete empty ink tank, corresponding first pipeline, the 3rd pipeline and the ink supply pipeline of a complete empty colour ink box, is 120ml; In order to make the force value in this space reach 36KPA, during vavuum pump need aspirate between clearancen 65% of gas volume, i.e. 120 * 65%=78 (ml); And the speed of exhaust of the vavuum pump that is adopted in the present embodiment is 2.3ml/s; Therefore, vavuum pump suction duration=gas volume is counted the ÷ speed of exhaust=78 ÷ 2.3, promptly approximates 33.9 (s).So identifying for the print cartridge identification module is the situation of a colour ink box, the first scheduled duration T1 in the vavuum pump control module was set to 34 seconds, and then to carry out the first scheduled duration T1 be 34 seconds operation to vavuum pump control module control vavuum pump.
When if the print cartridge that the print cartridge identification module identifies is a black print cartridge and one or more colour ink box; So on the basis of a black print cartridge; Colour ink box of every increase; It is on 56 seconds basis, to increase constant C=22 that the vavuum pump control module is determined first scheduled duration, and then the duration of vavuum pump control module control vavuum pump operation is also with regard to constant C=22 of corresponding increase.
Above is that complete following empty of situation is determined the duration of taking out negative pressure and enough had the colour ink box of ink and ink tank to take out negative pressure to residue according to colour ink box and the ink tank that is connected with colour ink box; And big capacity ink box is taken out the also enough negative pressure of taking out of duration of negative pressure to corresponding low capacity print cartridge; Therefore; The size of the print cartridge capacity that identifies regardless of the print cartridge identification module; Be to determine first duration as follows in the vavuum pump control module: when the print cartridge identification module identified a black print cartridge or a colour ink box, the first scheduled duration T1 of vavuum pump control module control vavuum pump operation was 56 seconds or 34 seconds; When the print cartridge identification module identifies when comprising a black print cartridge or a colour ink box at interior N print cartridge; This numerical value of N is greater than 1 and less than 6 natural number; Then the vavuum pump control module can be determined the first scheduled duration TN according to formula: T1+ (N-1) * C; Thereby the first scheduled duration TN of vavuum pump control module control vavuum pump operation is 56+ (N-1) * 22 or 34+ (N-1) * 22.
