The invention provides an electrolysis control circuit and a disinfectant manufacturing device, which are used for solving the problems of electromagnetic noise generated during electrolysis and lower electrolysis efficiency in the prior art.
Example 1
As shown in fig. 2, an embodiment of the present invention provides an electrolysis control circuit including: the control chip MCU, the electrolytic component, the second resistor R2 and the diode D1.
The control chip MCU is provided with an output port and a feedback port, wherein the output port is used for outputting voltage, and the feedback port is used for receiving feedback signals. The electrolysis assembly is composed of a first electrode and a second electrode, the first electrode is connected with the output port, the second electrode is grounded through a first resistor R1, and the first electrode and the second electrode are suitable for being placed into electrolyte for electrolysis. One end of the second resistor R2 is connected with the first electrode, the other end of the second resistor R2 is grounded, and the feedback port is connected between the second resistor R2 and the output port. The positive electrode of the diode D1 is connected between the second electrode and the first resistor R1, and the negative electrode is connected to the feedback port. The control chip MCU supplies power to the control chip MCU through a power supply. Of course, the control chip MCU may be a DC-DC chip.
In this embodiment, the feedback signal is a voltage signal of the diode D1 received by the feedback port. The first electrode and the second electrode are placed in an electrolyte prior to electrolysis. And then the enabling pin of the control chip MCU is connected with one I/O port of the signal source, the on and off of the control chip MCU is controlled through the high and low levels of the I/O port of the signal source, and when the I/O is at the high level, the control chip MCU is connected with a power supply to start working. After the electrolysis is started, the output port of the control chip MCU outputs a certain voltage, so that the two electrode plates start to electrolyze the electrolyte.
When the concentration of the electrolyte meets the electrolysis requirement, the output current can be stably increased to a preset constant current value, and the control chip MCU controls the output port to output in a constant current electrolysis mode, so that the electrolysis current is increased. And as the electrolyte is electrolyzed, ions in the electrolyte gradually increase, so that the resistance of the electrolyte is reduced, and the current is steadily increased under the action of the ions and the electrolyte. When the current increases to a preset current value, the voltage at two ends of the first resistor R1 is greater than the voltage at two ends of the second resistor R2, so that the diode D1 is turned on, and the feedback voltage received by the feedback port of the control chip MCU is the voltage at two ends of the first resistor R1. Then, since the ion concentration in the electrolyte is sufficiently large at this time, the output current can be stably increased to a preset constant value, and the current is kept unchanged after reaching the constant value.
As electrolysis proceeds, the ion concentration of the electrolyte begins to decrease, the conductivity becomes weak, the ion concentration in the electrolyte is insufficient to maintain the output current at a preset constant value, the current in the circuit begins to decrease, and the voltage across the electrode pad begins to increase. At this time, the control chip MCU controls the output port to output in the constant voltage electrolysis mode. The voltage across the first resistor R1 starts to decrease and the voltage across the second resistor R2 starts to increase. When a certain moment is reached, the voltage across the first resistor R1 is smaller than the voltage across the second resistor R2, so that the diode D1 is turned off. At this time, the feedback voltage received by the feedback port is the minimum value.
When the voltage at two ends of the second resistor R2 is reduced to a preset feedback voltage, namely when the electrolysis of the electrolyte reaches a certain degree, the output voltage of the control chip MCU is increased to a preset constant voltage value, so that the electrolyte is electrolyzed at a preset maximum voltage until the electrolysis is finished. Thus, the electrolysis current can be well controlled, electromagnetic noise generated by the intermittent control electrode plate is eliminated, and the electrolysis efficiency is improved.
Of course, if the electrolyte does not meet the electrolysis requirement at first, that is, the output current cannot be stably increased to the preset constant current value, the control chip MCU directly controls the output port to output in the constant voltage electrolysis mode.
As an alternative embodiment, since the voltage across the first resistor R1 is smaller than the voltage across the second resistor R2, so that the diode D1 is turned off, the voltage across the second resistor R2 gradually increases during the subsequent electrolysis. When the voltage at two ends of the second resistor R2 is increased to the preset value again, the output voltage is controlled to be increased to the preset maximum voltage, so that the electrolyte is electrolyzed at the preset maximum voltage until the electrolysis is finished. Therefore, the electrolyte can be further fully electrolyzed, the electrolysis current can be well controlled, electromagnetic noise generated by the intermittent control electrode plate is eliminated, and the electrolysis efficiency is improved.
Optionally, in an embodiment of the present invention, as shown in fig. 3, the electrolysis control circuit further includes an amplifying circuit, where an input end of the amplifying circuit is connected between the first resistor R1 and the second electrode, and an output end of the amplifying circuit is connected to an anode of the diode D1.
The amplifying circuit comprises an operational amplifier and a feedback resistor Rf, wherein the non-inverting input end of the operational amplifier is connected between the first resistor R1 and the second electrode, the inverting input end of the operational amplifier is grounded through a fourth resistor R4, and the output end of the operational amplifier is connected with the anode of the diode D1. One end of the feedback resistor Rf is connected with the inverting input end, and the other end is connected with the output end.
Therefore, through the arrangement of the amplifying circuit, the voltage at two ends of the first resistor R1 can be amplified, so that the conducting voltage of the diode D1 is adjusted, the diode D1 can be cut off when the voltage at two ends of the second resistor R2 needs to be increased to a higher voltage, and then the electrolytic current and the electrolytic voltage in the electrolytic process are adjusted, and the electrolytic efficiency is improved.
The amplifying circuit further comprises a fifth resistor R5, wherein the fifth resistor R5 is connected between the first resistor R1 and the second electrode, and the other end of the fifth resistor R5 is connected with the non-inverting input end of the operational amplifier.
Optionally, in an embodiment of the present invention, as shown in fig. 4, the electrolysis control circuit further includes a third resistor R3, where the third resistor R3 is disposed between the first electrode and the second resistor R2, and the feedback port is connected between the second resistor R2 and the third resistor R3.
Therefore, the third resistor R3 can divide the voltage at two ends of the second resistor R2, so that the voltage at two ends of the second resistor R2 is reduced, the diode D1 can be cut off when the voltage at two ends of the second resistor R2 needs to rise to a higher voltage, and then the electrolytic current and the electrolytic voltage in the electrolytic process are adjusted, and the electrolytic efficiency is improved.
Optionally, in the embodiment of the present invention, as shown in fig. 4, an inductance element L1, a filter capacitor C1, and a rectifier diode D2 are further included. One end of the inductance element L1 is connected to the output port, and the other end is connected to the first electrode. One end of the filter capacitor C1 is connected with the first electrode, and the other end of the filter capacitor C is grounded. The negative electrode of the rectifying diode D2 is connected with the output port, and the positive electrode of the rectifying diode D2 is grounded.
Example 2
The embodiment of the invention also provides a disinfectant manufacturing device, which comprises the electrolysis control circuit according to any embodiment.
The beneficial effects are that: the arrangement is such that after start-up the electrolysis process starts to electrolyze at maximum current, at which time the voltage of the first resistor is higher than the voltage of the second resistor, so that the diode is turned on. The electrolysis efficiency is high at this time. Along with the progress of electrolysis, the current gradually decreases, the voltage gradually rises, at the moment, the diode is cut off, and when the current flowing through the electrode plate is smaller than the preset current and the voltage at the two ends of the electrode plate is equal to the preset voltage, the electrolyte is electrolyzed with the preset maximum voltage until the electrolysis is finished. Thus, the electrolysis current can be well controlled, electromagnetic noise is eliminated, and the electrolysis efficiency can be improved.
Example 3
The embodiment of the invention also provides an electrolysis control method applied to the disinfectant manufacturing device according to the embodiment, which comprises the following steps:
s1, acquiring feedback voltage from the feedback port;
s2, judging whether the feedback voltage is reduced to a preset feedback voltage or not;
s3, if the feedback voltage is reduced to the preset feedback voltage, the output voltage is controlled to be increased to the preset maximum voltage.
The electrolysis control circuit of the disinfectant manufacturing device is provided with a control chip MCU, and a feedback port of the control chip MCU is used for acquiring a feedback signal, and in the embodiment, the feedback voltage is used as a feedback signal for explanation.
Before electrolysis, the first electrode and the second electrode are put into electrolyte, and after electrolysis is started, the output port of the control chip MCU outputs a certain voltage, so that the two electrode plates start to electrolyze the electrolyte.
In the electrolysis process, the output voltage of the output port is increased, so that the output current is gradually increased, and when the current is increased to a preset current value, the voltage at the two ends of the first resistor R1 is larger than the voltage at the two ends of the second resistor R2, so that the diode D1 is conducted, and the feedback voltage received by the feedback port of the control chip MCU is the voltage at the two ends of the first resistor R1. Then, the control chip MCU adjusts the output voltage according to the feedback voltage received by the feedback port, and the output current can be stabilized at a preset current value and kept unchanged because the ion concentration in the electrolyte is enough to keep the output current stable at the moment.
As electrolysis proceeds, the ion concentration of the electrolyte begins to decrease, conductivity becomes weak, the ion concentration in the electrolyte is insufficient to keep the output current stable, so that the current in the circuit begins to decrease and the voltage across the electrode pad begins to increase. At this time, the voltage across the first resistor R1 starts to decrease, and the voltage across the second resistor R2 starts to increase. When a certain moment is reached, the voltage across the first resistor R1 is smaller than the voltage across the second resistor R2, so that the diode D1 is turned off. At this time, the feedback voltage received by the feedback port is the minimum value.
When the voltage at two ends of the second resistor R2 is reduced to a preset feedback voltage, namely when the electrolysis of the electrolyte reaches a certain degree, after the feedback port receives the feedback signal, the output voltage is controlled to rise to a preset maximum voltage, so that the electrolyte is electrolyzed at the preset maximum voltage until the electrolysis is finished. Thus, the electrolysis current can be well controlled, electromagnetic noise generated by the intermittent control electrode plate is eliminated, and the electrolysis efficiency is improved.
As an alternative embodiment, since the voltage across the first resistor R1 is smaller than the voltage across the second resistor R2, so that the diode D1 is turned off, the voltage across the second resistor R2 gradually increases during the subsequent electrolysis. When the voltage at two ends of the second resistor R2 is increased to the preset value again, the output voltage is controlled to be increased to the preset maximum voltage, so that the electrolyte is electrolyzed at the preset maximum voltage until the electrolysis is finished. Therefore, the electrolyte can be further fully electrolyzed, the electrolysis current can be well controlled, electromagnetic noise generated by the intermittent control electrode plate is eliminated, and the electrolysis efficiency is improved.
In this embodiment, before the obtaining the feedback voltage from the feedback port, the method includes:
s0. obtain an activation signal; and controlling the output current value to be increased to a preset current value according to the starting signal. And when the output current value is increased to the preset current value, controlling the output current value to be unchanged.
In the electrolysis process, the output voltage of the output port is increased, so that the output current is gradually increased, and when the current is increased to a preset current value, the voltage at the two ends of the first resistor R1 is larger than the voltage at the two ends of the second resistor R2, so that the diode D1 is conducted, and the feedback voltage received by the feedback port of the control chip MCU is the voltage at the two ends of the first resistor R1. Then, the control chip MCU adjusts the output voltage according to the feedback voltage received by the feedback port, and the output current can be stabilized at a preset current value and kept unchanged because the ion concentration in the electrolyte is enough to keep the output current stable at the moment. By the arrangement, the electrolysis can be performed at the same electrolysis speed all the time in the electrolysis process, so that the electrolysis device can be ensured to keep higher electrolysis efficiency all the time.

The beneficial effects are that: the arrangement is such that after start-up the electrolysis process starts to electrolyze at maximum current, at which time the voltage of the first resistor is higher than the voltage of the second resistor, so that the diode is turned on. The electrolysis efficiency is high at this time. Along with the progress of electrolysis, the current gradually decreases, the voltage gradually rises, at the moment, the diode is cut off, and when the current flowing through the electrode plate is smaller than the preset current and the voltage at the two ends of the electrode plate is equal to the preset voltage, the electrolyte is electrolyzed with the preset maximum voltage until the electrolysis is finished. Thus, the electrolysis current can be well controlled, electromagnetic noise is eliminated, and the electrolysis efficiency can be improved.
