Description

Technical Field

[0001] This utility model relates to the field of mouthwash production technology, and in particular to an electrolytic mouthwash production device. Background Technology

[0002] Electrolysis technology generates strong oxidizing substances such as hypochlorous acid (HClO) by electrolyzing saline or specific solutions. These components have broad-spectrum bactericidal effects and are gentler than traditional chemical preservatives (such as alcohol), making them suitable for sensitive individuals. Furthermore, electrolysis reduces the use of chemical additives, aligning with the trend of green manufacturing. In summary, mouthwash produced by electrolysis has advantages such as simple formulation, a refreshing and non-greasy taste, and high bactericidal efficiency. However, current production processes often use high-concentration sodium chloride solutions to electrolyze at the anode to generate chlorine gas, which then undergoes a series of chemical reactions to obtain the final product. This method carries the risk of toxic chlorine gas leakage, which may harm the respiratory tract, skin, and other organs of operators. In addition, the aforementioned production process generates alkaline wastewater, which requires acidification or other pollution-free treatment before discharge. Therefore, traditional processes suffer from high operational risks, complex processes, and high costs.

[0003] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0004] In response to the problems pointed out in the background art, this utility model proposes an electrolytic mouthwash production device, which uses a low-concentration salt solution for electrolysis and achieves zero emission of harmful gases and waste liquid through ingenious design of the electrolysis device, thereby realizing safe, efficient and automated production.

[0005] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0006] In some embodiments, an electrolytic mouthwash production apparatus is provided, comprising: a mixing system, an electrolysis system, an acid-base adjustment system, and a filling system connected in series; the electrolysis system includes a storage tank and an electrolysis device, the mixing system is connected to the storage tank via a pipeline, a circulating pipeline is provided between the storage tank and the electrolysis device, wherein at least one pipeline is equipped with a first control pump.

[0007] The electrolysis device includes a cathode chamber containing a cathode electrode and an anode chamber containing an anode electrode, with a proton channel between the cathode and anode electrodes. The cathode chamber has a gas outlet, and the anode chamber has an inlet and an outlet. The electrolyte in the storage tank enters the anode chamber through the inlet, undergoes electrolysis in the anode chamber, and then flows out through the outlet, returning to the storage tank via a pipeline, forming a closed loop. The proton channel enables the transport of hydrogen ions from the anode chamber to the cathode chamber, where they are reduced to H2 and discharged. Simultaneously, an oxidation reaction occurs in the anode chamber, yielding an electrolyte containing hypochlorous acid and hypochlorite. Because the cathode chamber utilizes hydrogen ions transported from the anode chamber through the proton channel, rather than hydrogen ions generated by the dissociation of water within the cathode chamber, no hydroxide ions are produced in the cathode chamber, thus eliminating waste liquid generation at its source and overcoming the technical problem of producing alkaline waste liquid in existing technologies.

[0008] The storage tank is connected to the acid-base adjustment system via a pipeline, and the electrolyte that has been electrolyzed in the storage tank is transported to the acid-base adjustment system to adjust the pH value.

[0009] The pH adjustment system is connected to the filling system, and the electrolyte with adjusted pH value is transported to the filling system for filling.

[0010] In some embodiments, the zero-gap bonding of the cathode electrode and / or anode electrode with the proton channel can reduce the resistance between the anode and cathode electrodes, increase the electrolysis current, and thus improve the electrolysis efficiency. When the cathode electrode and / or anode electrode is bonded to the proton channel with zero gap, the contact area between the electrode bonded to the proton channel and the proton channel is smaller than the area of ​​the proton channel, so as to facilitate the smooth escape of electrolysis products.

[0011] In some embodiments, when the cathode electrode and / or anode electrode are in zero-gap contact with the proton channel, the electrode in zero-gap contact with the proton channel is provided with at least one through-path, which can accelerate the escape of hydrogen gas generated by electrolysis between the cathode electrode and the proton channel and prevent the cathode electrode and the proton channel from separating; it can also accelerate the export of electrolysis products between the anode electrode and the proton channel, while accelerating the inflow of electrolyte and improving electrolysis efficiency.

[0012] In some embodiments, the inlet is located away from the anode electrode, and the outlet is located close to the anode electrode. This not only maximizes the content of electrolytic products in the electrolyte and improves the bactericidal effect of the mouthwash, but also increases the turbulence of the electrolyte in the anode chamber and improves the electrolysis efficiency.

[0013] In some embodiments, the storage tank is equipped with a thermometer, and a cooling system is provided outside the storage tank; by using the cooling system and the thermometer in combination, the electrolysis reaction can be carried out at a low temperature, thereby reducing the occurrence of oxygen-producing side reactions and improving electrolysis efficiency.

[0014] In some embodiments, the mixing system includes a mixing tank, a water inlet device, and a salt inlet device, which are respectively connected to the mixing tank via pipelines. Separating the water inlet device and the salt inlet device allows for flexible adjustment of the amount of electrolyte in the electrolyte solution as needed, and the operation is simple.

[0015] The acid-base adjustment system includes a pH adjustment tank and an acid storage tank connected to it. A first valve is provided on the connecting pipeline, and the storage tank is connected to the pH adjustment tank through a pipeline.

[0016] In some embodiments, the acid outlet of the acid storage tank is located above the acid inlet of the pH adjustment tank, and a first valve is provided on the pipeline from the acid storage tank to the pH adjustment tank. Positioning the acid storage tank above the pH adjustment tank allows the acid to drip into the pH adjustment tank under gravity, facilitating pH adjustment of the electrolyte.

[0017] In some embodiments, the mixing tank is equipped with a stirring device and a heating device, which can accelerate the mixing of pure water and salt solution. In particular, when solid salt is directly fed into the salt feeding device, the salt can be dissolved in the water more quickly, reducing the process time.

[0018] In some embodiments, the storage tank is equipped with a first conductivity meter and a first pH meter, and the pH adjustment tank is equipped with a second pH meter;

[0019] A second valve is installed on the pipeline connecting the mixing system and the storage tank.

[0020] These embodiments can seal the electrolysis and acid-base neutralization reactions within the system, eliminating the need to activate the system to detect parameters. The reaction endpoint can be determined by observing changes in the conductivity and pH of the electrolyte.

[0021] In some embodiments, the electrolytic mouthwash production apparatus further includes a control system electrically connected to at least one functional component for controlling the production apparatus and achieving automated production. The control system can electrically control the mixing system, electrolysis system, and acid-base adjustment system within the apparatus. After setting the corresponding parameters, the production apparatus can automatically mix, electrolyze, and adjust the acid-base according to the set parameters, automatically transferring materials in each relevant system without requiring system sampling and monitoring, thus achieving fully automated control.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are:

[0023] 1. The electrolytic mouthwash production device of this application, through its ingenious structural design, achieves a pathway where only hydrogen gas is discharged from the cathode chamber, while the electrolysis products enter and flow out from the anode chamber. This overcomes the defect of existing electrolysis devices that continuously generate alkaline solution, eliminating the need for waste liquid treatment, saving waste liquid treatment costs, and being environmentally friendly.

[0024] 2. The electrolytic mouthwash production device in this application, by setting up instruments such as conductivity meters and pH meters, enables full monitoring of the electrolysis reaction and acid-base neutralization reaction under closed conditions, avoiding the risk of leakage of harmful gases such as chlorine due to system opening, and avoiding personal injury and environmental pollution.

[0025] 3. The electrolytic mouthwash production apparatus in this application achieves fully automatic control through the setting of the control system, which not only reduces manual intervention and avoids errors caused by human operation, but also avoids gas leakage and uncertainties introduced by system opening, making the quality between batches stable and controllable.

[0049] Example 1: Electrolytic mouthwash production apparatus that does not produce waste liquid

[0050] This embodiment discloses an electrolytic mouthwash production apparatus, referring to... Figure 1 , Figure 2 and Figure 3 It includes a mixing system 10, an electrolysis system 20, an acid-base adjustment system 30, and a filling system 40.

[0051] The electrolysis system 20 includes a storage tank 21 and an electrolysis device 22. The storage tank 21 is connected to the mixing system 10 via a pipeline. The uniformly mixed brine in the mixing system 10 is fed into the storage tank 21 through the pipeline. A circulation pipeline is provided between the storage tank 21 and the electrolysis device 22. A first control pump 214 is installed on this pipeline to provide power for the flow of electrolyte between the storage tank 21 and the electrolysis device 22, improving electrolysis efficiency and ensuring more complete electrolysis of the electrolyte in the storage tank 21, thus saving time required for the overall production process. The storage tank 21 is connected to the acid-base adjustment system 30 via a pipeline. The electrolyte that has completed electrolysis in the storage tank 21 is transported to the acid-base adjustment system 30 to adjust the pH value to the required value. The acid-base adjustment system 30 is connected to the filling system 40, and the pH-adjusted electrolyte is transported to the filling system 40 for filling.

[0052] Taking sodium chloride solution as the electrolytic raw material, the dilute sodium chloride solution in the storage tank 21 flows rapidly between the storage tank 21 and the electrolysis device 22 under the power of the first control pump 214. The solution is rapidly electrolyzed in the electrolysis device 22 to produce hypochlorous acid and its salt. The hypochlorous acid and its salt have a good bactericidal effect and are a highly efficient bactericidal, refreshing and non-sticky mouthwash.

[0053] The first control pump 214 between the storage tank 21 and the electrolysis device 22 is installed on the return pipeline from the electrolysis device 22 to the storage tank 21, which can also provide power for the rapid flow of electrolyte between the storage tank 21 and the electrolysis device 22.

[0054] Electrolysis unit 22 of the electrolytic mouthwash production apparatus, refer to Figure 2 , Figure 3 It includes an anode chamber 221 and a cathode chamber 222. An anode electrode 224 is disposed in the anode chamber 221, and a cathode electrode 225 is disposed in the cathode chamber 222. A proton channel 223 is provided between the anode electrode 224 and the cathode electrode 225, allowing only hydrogen ions to pass through. The anode chamber 221 has a liquid inlet 2211 and a liquid outlet 2212, and the cathode chamber 222 has a gas outlet 2221.

[0055] The proton channel 223 is configured as a proton membrane for transporting hydrogen ions from the anode chamber 221 to the cathode chamber 222.

[0056] The electrolyte flowing from storage tank 21, driven by the first control pump 214, enters the anode chamber 221 through inlet 2211. In the anode chamber 221, it comes into contact with the anode electrode 224, loses electrons, and undergoes an oxidation reaction. Simultaneously, hydrogen ions dissociated from the electrolyte pass through proton channel 223 to the cathode chamber 222, gain electrons at the cathode electrode 225, undergo a reduction reaction, and produce hydrogen gas. The hydrogen gas is discharged from the system through exhaust port 2221. The electrolyzed electrolyte then flows back to storage tank 21 through outlet 2212 via pipeline.

[0057] In this embodiment, the electrolytic mouthwash production device has an electrolysis unit 22 that allows the electrolyte to enter, electrolyze, and exit only from the anode chamber 221, generating hypochlorous acid and hypochlorite. After pH adjustment, the desired electrolytic mouthwash is obtained. The cathode chamber 222 does not require electrolyte entry. Hydrogen ions are transported from the anode chamber to the cathode chamber through the proton channel 223, and only hydrogen gas is generated on the cathode electrode 225 without producing strongly alkaline byproducts, reducing the procedures and costs of subsequent waste liquid treatment.

[0058] Example 2: Zero-gap bonding between electrode and proton channel

[0059] This embodiment refers to Figure 2 and Figure 3 The cathode electrode 225 and the proton channel 223 are fitted together with zero gap. The area of ​​the cathode electrode 225 is smaller than the contact area between the proton channel 223 and the cathode electrode 225, so that the generated hydrogen gas will not be blocked between the cathode electrode 225 and the proton channel 223. This prevents the cathode electrode 225 and the proton channel 223 from separating or partially separating due to the hydrogen gas generated in the middle, which would reduce the electrolysis efficiency or even cause the electrolysis to stop.

[0060] The cathodic reduction reaction is as follows:

[0061] 2H + +2e - →H2↑

[0062] In one specific embodiment, the cathode electrode 225 is provided with a through hole 2251 for exporting hydrogen gas generated between the cathode electrode 225 and the proton channel 223 through the through hole 2251, thereby further preventing the cathode electrode 225 and the proton channel 223 from separating.

[0063] In this configuration, the anode electrode 224 is fitted with the proton channel 223 with zero gap. The area of ​​the anode electrode 224 is smaller than the contact area between the proton channel 223 and the anode electrode 224, making it easier for the electrolytic products generated by the anodic electrolysis to be extracted from between the anode electrode and the proton channel 223. Combined with the zero-gap fit of the cathode electrode 225 with the proton channel 223, the resistance between the anode electrode 224 and the cathode electrode 225 is minimized. Under the same voltage, the current can be increased, thereby improving the electrolysis efficiency.

[0064] The anode electrode 224 is provided with a through hole, which makes it easier for the electrolytic products generated by the anode electrolysis to be extracted from the anode electrode 224 and the proton channel 223, and allows the electrolyte to come into contact with the anode electrode 224 more quickly, thus accelerating the reaction rate.

[0065] If the cathode electrode 225 is not in zero-gap contact with the proton channel 223, then pure water needs to be pre-added to the cathode chamber or a conductive material needs to be placed between the cathode electrode 225 and the ion channel 223 to ensure the flow of electrons on the cathode electrode and to ensure the electrolysis reaction proceeds.

[0066] Example 3: Properly setting the anode inlet and outlet

[0067] In this embodiment, the inlet 2211 is positioned away from the anode electrode 224, and the outlet 2212 is positioned close to the anode electrode 224. This allows the electrolyte that has just been electrolyzed to be discharged from the outlet 2212 into the anode chamber 221, while the electrolyte that is newly pumped into the anode chamber 221 from the storage tank 21 enters the anode chamber 221 from a position away from the anode electrode 224. This increases the flow of electrolyte in the anode chamber 221, the electrolysis time, and the turbulent state, thereby further improving the electrolysis efficiency.

[0068] Example 4: Low-Temperature Operation of Electrolysis Process

[0069] In this embodiment, a thermometer 213 is provided on the storage tank 21, and a cooling device (not shown) is provided outside the storage tank 21 to cool the electrolyte during electrolysis, keeping the electrolyte at a lower temperature. Because at higher temperatures, anodic electrolysis makes it easier for chloride ions and hydroxide ions to lose electrons and be oxidized, thus producing more oxygen and causing unnecessary waste of energy and time; while at lower temperatures, chloride ions are more likely to lose electrons and be oxidized, thus producing more chlorine gas, which further reacts to produce more hypochlorous acid or hypochlorite ions, improving the energy conversion rate and effectively shortening the electrolysis time. Furthermore, the chlorine gas produced by anodic electrolysis is more easily dissolved in water at low temperatures, preventing chlorine gas from escaping from the water and improving the conversion rate of the salt solution to the effective components.

[0070] Example 5: pH adjustment of alkaline electrolyte

[0071] In this embodiment, the mixing system 10 includes a mixing tank 11. The mixing tank 11 is connected to the water inlet device 12 and the salt inlet device 13 through conveying pipelines. The purified pure water and concentrated brine are conveyed to the mixing tank 11 through the water inlet device 12 and the salt inlet device 13, respectively, and mixed evenly in the mixing tank 11.

[0072] The acid-base adjustment system 30 includes a pH adjustment tank 31 and an acid storage tank 32. The pH adjustment tank 31 is connected to the storage tank 21 through a pipeline. The electrolyte that reaches the end of the electrolysis is transported to the pH adjustment tank 31. The electrolyte at the end of the electrolysis is alkaline because hydrogen ions are transported to the cathode chamber and hydroxide ions are left behind.

[0073] The reaction principle can be understood as follows: the anode electrode 224 loses electrons and undergoes an oxidation reaction to produce chlorine gas. The chlorine gas reacts with water to produce hypochlorous acid and hydrochloric acid. Hydrogen ions from the dissociation of water in the anode chamber 224 reach the cathode chamber 222 through the proton channel 223, where they gain electrons at the cathode electrode 225 and are reduced to produce hydrogen gas. According to the reaction principle, the transfer of two electrons results in the generation of one hydrogen gas at the cathode electrode and two hydroxide ions and one chlorine gas at the anode electrode 224. The chlorine gas reacts with water to produce one hypochlorous acid and one hydrogen chloride. The two hydroxide ions further react with one hypochlorous acid and one hydrogen chloride to produce water, one hypochlorite ion, and one chloride ion. Hypochlorous acid is a weak acid, and its corresponding hypochlorite aqueous solution is alkaline, resulting in an overall alkaline anolyte composition at the anode.

[0074] The reaction formula is as follows:

[0075] Cathode: 2H + +2e - →H2↑

[0076] Anode: 2Cl - -2e - Cl₂ + H₂O → HClO + HCl

[0077]

[0078] 2OH - +HClO + HCl → 2H₂O + ClO - +Cl -

[0079]

[0080] The acid storage tank 32 is connected to the pH adjustment tank 31. The acid solution in the acid storage tank 32 is input into the pH adjustment tank 31 to adjust the electrolyte in the pH adjustment tank 31 to the required pH value.

[0081] In this embodiment of the electrolytic mouthwash production apparatus, pure water enters the mixing tank 11 via the water inlet device 12, and concentrated salt water or solid salt enters the mixing tank 11 via the salt inlet device 13. After the pure water and concentrated salt water or solid salt are thoroughly mixed in the mixing tank 11, the desired concentration of salt water is obtained. This salt water is then transported to the storage tank 21 to become the electrolyte. To prepare for electrolysis, the first control pump 214 and the electrolysis device 22 are started sequentially. After electrolysis for a certain period, a sample is taken from the storage tank 21. Taking a concentrated sodium chloride solution as an example, the pH and available chlorine of the electrolyte are measured. Electrolysis is stopped once the target value is reached. The electrolyte after electrolysis is completed is transported to the pH adjustment tank 31. The acid stored in the acid storage tank 32 is added dropwise to the pH adjustment tank 31 to adjust the pH value, thus obtaining electrolytic mouthwash that meets the requirements.

[0082] Example 6: Adding acid solution by gravity

[0083] In this embodiment, the mixing tank 11 is also equipped with a heating device and a stirring device (not shown), which can accelerate the mixing of pure water and concentrated salt solution in the mixing tank 11. When used in conjunction with the external cooling device of the storage tank 21, it can quickly mix the electrolytic raw materials and cool them down, thereby improving efficiency and reducing process waiting time.

[0084] The acid outlet (not marked) of the acid storage tank 32 is located above the acid inlet (not marked) of the pH adjustment tank 31. A first valve 321 is installed on the pipeline between the two. When the first valve 321 is opened, the acid in the acid storage tank 32 can drip into the pH adjustment tank 32 by gravity. When the pH reaches the target value, the first valve 321 is closed. The acid is slowly added by gravity to prevent the reaction endpoint from being exceeded during acid-base adjustment, so that the acid-base adjustment is more accurate.

[0085] Example 7: Automatic monitoring of reaction progress

[0086] In this embodiment, the storage tank 21 is equipped with a first conductivity meter 211 and a first pH meter 212 to monitor the conductivity and pH of the electrolyte in the storage tank 21. As the electrolysis process progresses, the conductivity and pH of the electrolyte gradually increase. The principle can be referenced from the above-mentioned principle that the cationic products are alkaline. By adding the left and right sides of all the anode reaction equations respectively, the identical products on both sides are canceled out, resulting in the following reaction equation:

[0087] Cl - -2e - +2H₂O→2H + +HClO+OH -

[0088] The two hydrogen ions on the right side reach the cathode through proton channel 223 and react there. Therefore, the reaction at the anode can be simplified to:

[0089] Cl - -2e - +2H₂O→HClO+OH -

[0090] Hypochlorous acid is a weak acid that undergoes reversible electrolysis in water.

[0091]

[0092] Therefore, as the electrolysis process progresses, the total number of ions in the solution will increase, the conductivity will increase accordingly, and the alkalinity will gradually increase. The electrolysis endpoint can be monitored by monitoring the conductivity and pH of the electrolyte.

[0093] The pH adjustment tank 31 is equipped with a second pH meter 311, which is used to monitor the pH of the electrolyte in the pH adjustment tank 31 and indicate the product endpoint. There is no need to take out the electrolyte to test related indicators, thus avoiding the risk of chlorine gas generated during electrolysis escaping from the system and causing personal injury if the system is opened.

[0094] A second valve 112 is provided on the pipeline connecting the mixing tank 11 and the storage tank 21 to separate the mixing tank 11 and the storage tank 21 and prevent the chlorine gas generated during the electrolysis process from flowing back into the mixing tank 11 through the pipeline.

[0095] The above settings ensure that once electrolysis begins, the entire electrolysis system 20 and acid-base adjustment system 30 are in a closed state, and there is no risk of leakage of toxic gases such as chlorine generated during the electrolysis process, thus ensuring the safety of the environment and personnel.

[0096] The filling system 40 is connected to the pH adjustment tank 31 via a pipeline. A third valve 312 is installed on the pipeline to ensure that the electrolysis reaction and acid-base neutralization reaction, which produce toxic gases, are sealed in the electrolysis system 20 and the acid-base adjustment system 30, so that no gas escapes.

[0097] Example 8: Installation of power unit and monitoring device

[0098] In this embodiment, a fourth control pump 121 is provided on the pipeline from the water inlet device 12 to the mixing tank 21 to pump pure water into the mixing tank 21.

[0099] The pipeline from the salt inlet device 13 to the mixing tank 21 is equipped with a fifth control pump 131, which pumps concentrated salt solution or solid salt into the mixing tank 21.

[0100] The mixing tank 11 is equipped with a second conductivity meter 111, which can monitor the conductivity of the salt solution in the mixing tank 21 to obtain the salt solution concentration, thereby controlling the amount of liquid and salt fed in.

[0101] A second control pump 113 is installed on the pipeline from the mixing tank 11 to the storage tank 21, which is used to quickly pump the mixed salt solution in the mixing tank 11 into the storage tank 21.

[0102] Among them, a third control pump 215 is provided on the pipeline from storage tank 21 to pH adjustment tank 31, which is used to quickly pump the electrolyte that has reached the end of electrolysis into pH adjustment tank 31.

[0103] The pipeline from pH adjustment tank 31 to filling system 40 is equipped with a sixth control pump, which is used to pump the mouthwash that has completed pH adjustment in the pH adjustment tank into the filling system.

[0104] Example 9: Setting up a control system

[0105] In this embodiment, the electrolytic mouthwash production device also includes a control system (not shown). The control system can be electrically connected to one or more of the functional components such as valves, control pumps, and tanks mentioned above. According to the set values, it controls the start and stop of each functional component, so that the system can achieve the purpose of automatic control.

[0106] The control system is electrically connected to the mixing system 10, the electrolysis system 20, the pH adjustment system 30, the filling system 40, and the valves and control pumps on the connecting pipelines, and is used to control the operation of the entire system.

[0107] First, start the mixing system 10, turn on the fourth control pump 121 and the fifth control pump 131 to control the inflow of pure water and concentrated salt solution, and at the same time turn on the stirring system and heating system of the mixing tank 11. Based on the reading of the second conductivity meter 111, turn off the operation of the mixing system 10.

[0108] Open the second valve 112 and the second control pump 113 to pump the mixed salt solution into the storage tank 21. Start the cooling device outside the storage tank 21. After the salt solution in the mixing tank 11 is pumped into the storage tank 21, close the second valve 112 and the second control pump 113. After the thermometer 213 reaches the preset value, start the electrolysis device 22 and the first control pump 214 to start electrolysis.

[0109] The electrolyte is repeatedly circulated between the storage tank 21 and the electrolysis device 22 for electrolysis. When the first conductivity meter 211 and the first pH meter 212 reach the set values, the electrolysis device 22 and the first control pump 214 are turned off to stop electrolysis.

[0110] Start the third control pump 215 to pump the electrolyzed electrolyte into the pH adjustment tank 31. Open the first valve 321 to allow the dilute hydrochloric acid stored in the acid storage tank 32 to drip into the pH adjustment tank 31. When the reading of the first pH meter 311 reaches the set value, close the first valve 321 to obtain the desired electrolyzed mouthwash.

[0111] Open the third valve 312 and the sixth control pump 323 to pump the electrolyzed mouthwash into the filling system 40 and begin the filling process.

[0112] In this embodiment, after setting the parameters for each stage, the entire production process can be automatically controlled without human intervention or operation, which greatly reduces labor costs and lowers the possibility of the production equipment being contaminated and the possibility of the production equipment polluting the environment.

[0113] In this invention, when an acidic electrolyte is used for electrolysis or other interfering factors cause the electrolysis products to be acidic, the acid storage tank 32 can also be used to hold alkaline solution to adjust the acidity or alkalinity of the product to the required pH.

[0114] The flow rate and velocity of the control pump in the entire process system of this utility model are adjustable, and the set values ​​of each conductivity meter and pH meter are adjustable. The parameters can be adjusted according to different production batches and active ingredient concentration requirements to control output and indicators.

[0115] In addition to pre-setting indicators for automatic control, this system can also select certain indicators for automatic control while manually controlling the rest. For example, only the electrolysis system can be automatically controlled, while other parts can be manually adjusted as needed. The flexible and adjustable parameters and control methods of this invention provide greater operational flexibility for process production, especially during process debugging.

[0116] In this invention, the electrode can be made of conductive diamond or other conductive materials, such as one or a combination of ceramic, titanium, platinum, gold, titanium alloy, nickel, palladium, platinum-ruthenium alloy or stainless steel.

[0117] In this invention, at least one electrode of the integrated electrode module is made of conductive diamond material, for example, the anode electrode 224 is made of conductive diamond material, or the cathode electrode 225 is made of conductive diamond material.

[0118] In the prior art, electrodes used for electrolysis often use precious metal electrodes such as platinum, ruthenium, and iridium. Considering the limited resources of precious metals, the development prospects of such electrodes are limited. In this invention, conductive diamond electrodes are used, which reduces the dependence on precious metal resources. Considering that carbon resources for preparing conductive diamond are more abundant, this invention has better development prospects.

[0119] The mouthwash produced by this electrolytic mouthwash production device can be used not only as a mouthwash, but also in other situations requiring sterilization, such as air sterilization, fruit and vegetable sterilization, pet sterilization, environmental sterilization, and other disinfection scenarios. In addition, it can also be used in other scenarios where hypochlorous acid solution is used.

[0120] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0121] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
