Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.

The disinfection machine on the market at present usually adopts the working method of fixed power, fixed time to salt volume is as preparing the only change volume of sodium hypochlorite solution, and the concentration of the sodium hypochlorite solution of preparing also often depends on the salt content. However, different sodium hypochlorite solutions with different concentrations are needed for different scenes, and the concentration of the prepared sodium hypochlorite solution can be determined only by determining the salt adding amount by the preparation method, and when the salt adding amount cannot be determined, the solubility of the generated sodium hypochlorite solution is difficult to control.
Based on this, this technical scheme is through detecting the electric current volume between the electrolysis electrode in order to confirm the electric conductivity of electrolytic solution, according to the corresponding relation between electric conductivity and the salt volume to confirm the salt volume in the electrolytic solution, so that further control sodium hypochlorite solution's the formation solubility.
According to an embodiment of the present invention, there is provided a salt amount detection circuit, as shown in fig. 1, including: a first electrolysis electrode 11, a second electrolysis electrode 12 and a current amount collecting unit 13. Wherein, the distance between the first electrolysis electrode 11 and the second electrolysis electrode 12 is fixed; the current amount collecting unit 13 is connected to the first electrolysis electrode 11 or the second electrolysis electrode 12, and is used for collecting the amount of current between the first electrolysis electrode 11 and the second electrolysis electrode 12. The current amount collecting means 13 in FIG. 1 will be described by way of example as being connected to the first electrolysis electrode 11.
Specifically, the distance between the first electrolysis electrode 11 and the second electrolysis electrode 12 needs to be fixed, and the distance can be determined according to experimental data and the design requirements of technicians. The first electrolysis electrode 11 and the second electrolysis electrode 12 are respectively connected to an IO output port of the control chip, and the control chip provides fixed output voltage for the first electrolysis electrode 11 and the second electrolysis electrode 12. The output voltage value of the control chip can be determined according to experimental data and the design requirements of technicians. For example, the first electrolysis electrode 11 is connected to one IO output port of the control chip, the second electrolysis electrode 12 is connected to the other IO output port of the control chip, and the output voltage of the control chip is fixed.
The current amount acquisition unit 13 is connected to the salt amount detection circuit, and acquires the current amount between the first electrolysis electrode 11 and the second electrolysis electrode 12 to obtain the conductivity of the electrolytic solution. Specifically, the electrolytic solution is a salt solution composed of clear water and daily-use salt. The current collecting unit can be an analog-to-digital conversion chip, and the analog-to-digital conversion chip is connected to the first electrolysis electrode 11 or the second electrolysis electrode 12 to collect the current between the first electrolysis electrode and the second electrolysis electrode. Because the first electrolysis electrode 11 and the second electrolysis electrode 12 are both in the electrolytic solution, and the first electrolysis electrode 11 and the second electrolysis electrode 12 form a passage through the electrolytic solution, the current collecting chip can be connected to any one electrolysis electrode to obtain the current between the first electrolysis electrode 11 and the second electrolysis electrode 12. As shown in FIG. 1, a current amount collecting unit 13 is provided on the first electrolysis electrode 11 to collect the amount of current between the first electrolysis electrode and the second electrolysis electrode. The connection and operation of the current amount collecting unit 13 and the second electrolysis electrode 12 are the same as those of the first electrolysis electrode 11, and the description thereof is omitted.
Before the electrolysis is started to generate the disinfectant (sodium hypochlorite), the first electrolysis electrode 11 and the second electrolysis electrode 12 are powered, one of the electrolysis electrodes is at a high level, and the other electrolysis electrode is at a low level. Since the first electrolysis electrode 11 and the second electrolysis electrode 12 are in the electrolytic solution, a weak current can be generated between the first electrolysis electrode 11 and the second electrolysis electrode 12, and a path is formed in the first electrolysis electrode 11, the second electrolysis electrode 12 and the electrolytic solution, and then the current between the first electrolysis electrode 11 and the second electrolysis electrode 12 can be converted through the analog-to-digital conversion chip, so as to obtain the amount of current between the first electrolysis electrode 11 and the second electrolysis electrode 12.
The salt amount detection circuit provided in the present embodiment includes: the device comprises a first electrolysis electrode, a second electrolysis electrode and a current amount acquisition unit, wherein the distance between the first electrolysis electrode and the second electrolysis electrode is fixed, and the current amount acquisition unit is connected with the first electrolysis electrode or the second electrolysis electrode and is used for acquiring the current amount between the first electrolysis electrode and the second electrolysis electrode. The conductivity of the electrolytic solution where the electrolytic electrode is located can be determined by collecting the current amount through the salt amount detection circuit, so that the salt amount in the electrolytic solution is determined based on the conductivity, and the salt amount in the current electrolytic solution is accurately determined under the condition of uncertain salt adding amount.
Alternatively, as shown in fig. 2, an adjustable resistance resistor may be provided in the salt amount detection circuit for manually calibrating the detection circuit. Specifically, the adjustable resistance value resistor can be arranged on a connection path of the first electrolysis electrode and the control chip or on a connection path of the second electrolysis electrode and the control chip.
Optionally, as shown in fig. 3, the salt amount detection circuit further includes: and the control unit 14, wherein the control unit 14 at least comprises two output ends and is used for outputting a voltage with a fixed amplitude. The first output 141 of the control unit 14 is connected to the first electrolysis electrode 11, and the second output 142 of the control unit 14 is connected to the second electrolysis electrode 12. The first output terminal 141 of the control unit 14 applies the first electric signal output by the control unit to the first electrolysis electrode 11, and the second output terminal 142 of the control unit 14 applies the second electric signal output by the control unit to the second electrolysis electrode 12, so as to drive the first electrolysis electrode 11 and the second electrolysis electrode 12 to carry out electrolysis.
Due to the polarity of the first electrolysis electrode 11 and the second electrolysis electrode 12, ions in the electrolytic solution move in one direction, and the ion concentration between the first electrolysis electrode 11 and the second electrolysis electrode 12 changes.

Fig. 5 is a flowchart of a salt amount detecting method according to an embodiment of the present invention, as shown in fig. 5, the flowchart includes the steps of:
s11, obtaining the current amount between the first electrolysis electrode and the second electrolysis electrode.
The first electrolysis electrode and the second electrolysis electrode can periodically act as an electrolysis anode and an electrolysis cathode. The voltage amplitude applied to the first electrolysis electrode and the second electrolysis electrode by the control unit is fixed, and the change of the polarity does not change the current quantity between the first electrolysis electrode and the second electrolysis electrode. The current amount can be obtained by a current collecting unit connected to the salt amount detecting circuit, and for the detailed description, reference is made to the related description of the above embodiments, which is not repeated herein.
And S12, determining the conductivity corresponding to the current amount based on the current amount.
The electrolytic solution is a NaCl solution, and the conductivity of the NaCl solution can be directly regarded as the concentration of NaCl ions. If the input voltage is U, the input voltage can be regarded as a resistor with a constant resistance R under the condition of constant ion concentration, and the current is I ═ U/R. Taking the specific resistance of the salt quantity-influenced electrolytic solution as P, the distance-influenced length L of the first electrolytic electrode and the second electrolytic electrode, and the vertical cross section of the first electrolytic electrode and the second electrolytic electrode as the area S as an example, the resistance calculation formula R is PL/S, and the resistance R can be calculated by the formula.
By
The electrolysis instantaneous power can be calculated, and the conductivity of the electrolytic solution is fed back according to the I value in the electrolysis instantaneous power.
And S13, determining the salt amount in the current electrolytic solution based on the corresponding relation between the conductivity and the pre-established conductivity and salt amount.
Through a plurality of tests, the corresponding relation between the conductivity and the salt content can be established, the corresponding relation can be in a form of a corresponding table or a fitting formula, and a person skilled in the art can determine the corresponding relation according to actual needs, and the method is not specifically limited in this application. Specifically, after determining the conductivity, the processor of the disinfecting liquid manufacturing apparatus may traverse the correspondence between the conductivity and the salt amount, determining the salt amount corresponding to the conductivity of the present electrolytic solution.
The present embodiment provides a salt amount detection method for calculating the conductivity of an electrolytic solution in which a first electrolysis electrode and a second electrolysis electrode are located, by detecting the amount of current flowing between the first electrolysis electrode and the second electrolysis electrode. According to the pre-established corresponding relation between the conductivity and the salt amount, the salt amount in the current electrolytic solution can be determined. The method realizes accurate determination of the salt amount in the current electrolytic solution under the condition of uncertain salt adding amount, thereby being capable of controlling the generation concentration of the sodium hypochlorite solution.
In the present embodiment, a salt amount detection method is provided, which can be used in a disinfectant manufacturing apparatus, such as a disinfectant manufacturing machine, a disinfecting machine, etc., including the above-mentioned salt amount detection circuit. Fig. 6 is a flowchart of a salt amount detecting method according to an embodiment of the present invention, as shown in fig. 6, the flowchart includes the steps of:
s21, obtaining the current amount between the first electrolysis electrode and the second electrolysis electrode.
Specifically, the step S21 may include the following steps:
and S211, controlling the electric signals of the first electrolysis electrode and the second electrolysis electrode to be periodically inverted.
The electrical signal may be a high level or a low level applied to the first electrolysis electrode and the second electrolysis electrode. The periodic reversal of the electrical signal is that the first electrolysis electrode and the second electrolysis electrode periodically act as an electrolysis anode and an electrolysis cathode. For example, when the first electrolysis electrode is at a high level and the second electrolysis electrode is at a low level in the current control period, the first electrolysis electrode is controlled to be at the low level and the second electrolysis electrode is controlled to be at the high level after one control period. Wherein the control period may be determined by setting a duty ratio of the PWM wave.
S212, determining the current amount of the first electrolysis electrode and the second electrolysis electrode based on the periodically inverted electric signal.
Since the magnitude of the voltage applied to the first electrolysis electrode and the second electrolysis electrode is fixed, although the polarity of the first electrolysis electrode and the second electrolysis electrode is changed due to the periodically inverted electric signal, the ion concentration between the first electrolysis electrode and the second electrolysis electrode is uniform and does not change the amount of current between the first electrolysis electrode and the second electrolysis electrode. Therefore, by periodically inverting the electric signals of the first electrolysis electrode and the second electrolysis electrode, the current amount of current between the first electrolysis electrode and the second electrolysis electrode can be determined.
And S22, determining the conductivity corresponding to the current amount based on the current amount. For a detailed description, refer to the related description of step S12 corresponding to the above embodiment, and the detailed description is omitted here.
And S23, determining the salt amount in the current electrolytic solution based on the corresponding relation between the conductivity and the pre-established conductivity and salt amount. For a detailed description, refer to the related description of step S13 corresponding to the above embodiment, and the detailed description is omitted here.
The present example provides a salt amount detection method that periodically inverts by controlling electric signals applied to a first electrolysis electrode and a second electrolysis electrode, and determines periodically varying amounts of electric current of the first electrolysis electrode and the second electrolysis electrode based on the periodically inverted electric signals. The method avoids the ions in the electrolytic solution between the first electrolytic electrode and the second electrolytic electrode from flowing towards one direction by periodically reversing the electric signals applied to the first electrolytic electrode and the second electrolytic electrode, and ensures the constant number of the ions in the electrolytic solution, thereby ensuring the accurate acquisition of the amount of current between the first electrolytic electrode and the second electrolytic electrode. Meanwhile, the phenomenon of scaling of the electrolytic electrode caused by the fact that ions in the electrolytic solution flow towards one direction is avoided, the service life of the electrolytic electrode is prolonged, and the current detection precision is further guaranteed.
In accordance with an embodiment of the present invention, there is provided an embodiment of an electrolysis control method, it being noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system, such as a set of computer-executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than presented herein.
In the present embodiment, there is provided an electrolysis control method which can be used in a disinfectant liquid manufacturing apparatus, such as a disinfectant liquid manufacturing apparatus, a disinfecting machine, or the like, and fig. 7 is a flowchart of the electrolysis control method according to the embodiment of the present invention, as shown in fig. 7, the flowchart includes the steps of:
and S31, calculating the salt amount in the electrolytic solution. For a detailed description, refer to the related description of the salt amount detection method, and are not repeated herein.
And S32, determining the corresponding electrolyte concentration of the electrolytic solution based on the salt amount.
And determining the electrolyte concentration corresponding to the current electrolytic solution according to the calculated salt amount and the volume of the current electrolytic solution. The volume of the electrolytic solution may be determined according to the apparatus for containing the electrolytic solution. The electrolyte is NaCl, and the electrolyte concentration is determined based on the amount of salt in the current electrolytic solution and the amount of solvent corresponding to the electrolytic solution. Specifically, if it is determined that the amount of salt in the current electrolytic solution is M, the volume of the electrolytic solution is V1, and the density of the salt is fixed, the volume of salt in the electrolytic solution V2 can be determined based on the density of the salt and the amount of salt M, and thus the solvent amount V becomes V1 to V2, and the electrolyte concentration C becomes M/V.
And S33, judging whether the electrolyte concentration is consistent with the preset concentration.
The preset concentration is the concentration corresponding to the amount of the generated target sodium hypochlorite, different salt amounts correspond to different preset concentrations, under the condition of the same electrolysis parameters (electrolysis work), the electrolysis conversion rate of the sodium hypochlorite is different, and the higher the preset concentration is, the higher the amount of the generated sodium hypochlorite is. Therefore, the corresponding relation can be established according to the corresponding preset concentration of different salt amounts and the amount of the generated target sodium hypochlorite. And determining whether the current electrolyte concentration can generate a sodium hypochlorite solution meeting the concentration requirement or not according to the corresponding relation.
After determining the concentration of the desired sodium hypochlorite solution, a predetermined concentration corresponding thereto may be determined. And comparing the calculated electrolyte concentration corresponding to the current electrolytic solution with a preset concentration, determining whether the electrolyte concentration is consistent with the preset concentration, and executing the step S34 when the electrolyte concentration is inconsistent with the preset concentration, otherwise executing normal electrolysis operation.
And S34, adjusting the electrolysis parameters.
The electrolysis parameters are control parameters of the electrolysis process, wherein the electrolysis parameters may include electrolysis time, duty ratio adjustment, electrolysis work value and the like, and may also include other control parameters. When the electrolyte concentration is inconsistent with the preset concentration, the electrolysis parameters can be adjusted in order to ensure the generation concentration of the sodium hypochlorite. For example, if the electrolyte concentration is less than the preset concentration, the electrolysis time can be prolonged to increase the work of electrolysis and ensure the generation concentration of sodium hypochlorite; if the electrolyte concentration is higher than the preset concentration, the electrolysis time can be reduced, so that the work of electrolysis is reduced, and the generation concentration of sodium hypochlorite is ensured.
In the electrolysis control method provided by this embodiment, the electrolyte concentration corresponding to the current electrolytic solution is determined by obtaining the salt content in the electrolytic solution, whether the electrolyte concentration is consistent with the preset concentration is determined, and when the electrolyte concentration is inconsistent with the preset concentration, the electrolysis parameters are adjusted to electrolyze to obtain the sodium hypochlorite solution meeting the concentration requirement. The method can control the generation concentration of the sodium hypochlorite solution under the condition that the salt adding amount is difficult to determine, thereby ensuring that the concentration of the prepared sodium hypochlorite solution is not influenced by the salt adding amount and realizing the accurate control of the sodium hypochlorite generation amount.
In the present embodiment, there is provided an electrolysis control method which can be used in a disinfectant liquid manufacturing apparatus, such as a disinfectant liquid manufacturing apparatus, a disinfecting machine, or the like, and fig. 8 is a flowchart of the electrolysis control method according to the embodiment of the present invention, as shown in fig. 8, the flowchart includes the steps of:
and S41, calculating the salt amount in the electrolytic solution. For a detailed description, refer to the related description of step S31 corresponding to the above embodiment, and the detailed description is omitted here.
And S42, determining the corresponding electrolyte concentration of the electrolytic solution based on the salt amount. For a detailed description, refer to the related description of step S32 corresponding to the above embodiment, and the detailed description is omitted here.
And S43, judging whether the electrolyte concentration is consistent with the preset concentration. For a detailed description, refer to the related description of step S33 corresponding to the above embodiment, and the detailed description is omitted here.
And S44, when the electrolyte concentration is inconsistent with the preset concentration, adjusting the electrolysis parameters.
Specifically, the step S44 may include the following steps:
s441, determining a concentration difference between the electrolyte concentration and a preset concentration based on the electrolyte concentration and the preset concentration.
The electrolyte concentration is compared with the preset concentration, so that the size relation between the electrolyte concentration and the preset concentration can be determined, and then the concentration difference between the electrolyte concentration and the preset concentration is determined. Specifically, if the electrolyte concentration is a1 and the preset concentration is a2, the concentration difference D between the electrolyte concentration and the preset concentration may be calculated as a1 to a 2. If the calculated D value is positive, the electrolyte concentration is larger than the preset concentration; and if the calculated D value is negative, the electrolyte concentration is less than the preset concentration.
S442, determining an electrolysis correction coefficient based on the concentration difference.
The electrolysis correction coefficient is used for correcting electrolysis parameters so as to electrolyze and generate sodium hypochlorite meeting the concentration requirement. The electrolysis correction factor may be determined from a concentration difference between the electrolyte concentration and a preset concentration. For example, if 300mg/L of sodium hypochlorite is required to be generated, the programmed work done by electrolysis of the sterilizer is 300J, but since the electrolyte concentration affects the efficiency of the generation of sodium hypochlorite, the programmed work done is 300J X, wherein the value of X can be determined according to the determined salt content. If 2g of salt is electrolyzed and does work in 300ml of electrolytic solution (or preset concentration A2) for 300J to generate 300mg/L of sodium hypochlorite, namely the electrolysis correction coefficient X is 1.0, when the calculated salt amount in the electrolytic solution is 1g, if electrolysis is continuously performed according to the electrolysis work value 300J, the concentration of the generated sodium hypochlorite is less than 300mg/L and does not meet the disinfection requirement, the electrolysis work value can be corrected at the moment, the electrolysis correction coefficient X of the obtained 1g of salt in 300ml of electrolytic solution is 1.2, and the generation amount of the sodium hypochlorite can be accurately controlled to be 300 mg/L. From this program, the electrolytic work value corresponding to each electrolyte concentration can be determined, and thus the electrolytic correction factor, for example, the electrolytic correction factor X of 4g of salt in 300ml of electrolytic solution is 0.8. Therefore, the generation amount of the sodium hypochlorite is accurately controlled.
S443, adjusting the electrolysis parameters based on the electrolysis correction coefficient.
And adjusting electrolysis parameters according to the determined electrolysis correction coefficient so as to accurately control the generation amount of the sodium hypochlorite. Taking the electrolysis parameter as the electrolysis work, for example, if the electrolysis correction coefficient X is 1.2, the electrolysis work value for generating the preset amount of sodium hypochlorite is 300J × 1.2 ═ 360J, that is, under the current electrolytic solution, 360J of work is needed to obtain the preset amount of sodium hypochlorite. Therefore, the salt amount does not need to be added by a user accurately according to the requirement, and the generation amount of the sodium hypochlorite can be accurately controlled to prepare the disinfectant with different concentrations only by enough salt amount. The disinfectant with different concentrations can be respectively applied to different application scenes such as fruit cleaning, appliance cleaning, clothes cleaning or ground disinfection and the like.
Of course, the electrolysis time can also be controlled by selecting the electrolysis duty ratio using the known electrolyte concentration. The electrolyte concentration is not specifically limited in this application, and those skilled in the art can determine the electrolyte concentration according to actual needs, as long as the electrolysis parameters can be adjusted according to the concentration difference between the current electrolyte concentration and the preset concentration, and a preset amount of sodium hypochlorite can be generated.
In the electrolysis control method provided by this embodiment, the concentration difference between the electrolyte concentration and the preset concentration is calculated by comparing the electrolyte concentration with the preset concentration, the electrolysis correction coefficient in the electrolysis process is determined based on the concentration difference, and the electrolysis parameter is adjusted based on the electrolysis correction coefficient, so that the concentration of the sodium hypochlorite solution obtained by electrolysis meets the requirement. The method determines the electrolysis parameters through the electrolysis correction coefficient, avoids the problem of inaccurate sodium hypochlorite generation amount caused by the difference of the electrolysis efficiency under different electrolyte concentrations, and realizes the accurate control of the sodium hypochlorite generation amount.
