[0035] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0036] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0037] The applicant explains the related technologies mentioned in the background technology as follows:

[0038] The electrolyzed water after electrolysis has a bactericidal and disinfecting function. Using an electrolytic cell to electrolyze the incoming water can produce electrolyzed water with a bactericidal and disinfecting function. However, the electrolytic cell efficiency may be low during use, and the generated electrolyzed water may not reach the predetermined oxidation potential. The oxidation potential will decrease, and the sterilization rate will also decrease accordingly after testing. In severe cases, the sterilization effect will be lost, and the electrolytic water device will lose its due effectiveness. At the same time, if the electrolytic cell continues to be turned on and used when it is inefficient, the power consumption will also increase, and it will have a negative impact on the service life of the electrode, the core component of the electrolytic cell.

[0039] The main reason for the low efficiency of the electrolytic cell is that the method of electrolyzing tap water (containing chlorine) can generate hydroxyl radicals (·OH) under the action of an electric field, and the electrolysis process is very complicated.

[0040] Among them, the generation mechanism of chloride ions participating in the electrolysis process is as follows:

[0041] Anode: 2C l–2e – →C l 2 ,

[0042] Cathode: 2H + +2e – →H 2 ,

[0043] NaCl+H 2 O→NaCl O+H 2 ↑(produces sodium hypochlorite),

[0044] NaClO+H 2 O=HCl O+NaOH (forming hypochlorous acid),

[0045] HCl O→HCl+[O] (decomposes to produce new oxygen),

[0046] HCl+NaOH=NaCl+H 2 O (reduced to sodium chloride and water).

[0047] During the electrolysis process, oxygen is generated at the anode. When the dissolved oxygen in the water and the oxygen generated at the anode reach the cathode surface,

[0048] O 2 +e – =·O 2– (1)

[0049] O 2 +2e – +2H + =H 2 O 2 (2)

[0050] H 2 O 2 +2e – +H+=·OH+H 2 O(3),

[0051] H 2 O 2 +·O 2 –=·OH+O 2 +OH – (4)

[0052] HOC l+·O 2 –=O 2 +·OH+C l – (5).

[0053] H2O2 is obtained by reduction through reaction equations (1) and (2), and H 2 O 2 Hydroxyl radicals (·OH) can be generated directly on the cathode surface, and can also be generated through reaction (5) with extremely high oxidation potential. Hydroxyl radicals can react instantly with organic matter, oxidizing it to generate stable substances that are harmless to the human body.

[0054] However, during the electrolysis of tap water, scale or sediment will gradually form on the electrode surface. The scale or sediment may contain metal oxides or other substances. The scale may also be adsorbed inside the electrode and is difficult to remove. In particular, when the water quality is poor and scale accumulates, it will seriously affect the electrolysis efficiency of the water electrolysis device. At the same time, the electrode surface is gradually covered by sediment, which will cause a certain degree of corrosion and attenuation, resulting in a decrease in electrolysis efficiency and a decrease in the oxidation potential of the electrolyte.

[0055] The main factor affecting the working efficiency of the electrolyzer is the reduction in the energy efficiency of the cathode plate. The reason for the reduction in the energy efficiency of the cathode plate is that there are metal ions such as calcium and magnesium in tap water. During the electrolysis process, there will be a large amount of metal oxides, hydroxide ions and carbonate ions in the cathode area. When calcium and magnesium ions pass through this area, calcium carbonate and magnesium hydroxide will be produced. Since calcium carbonate and magnesium hydroxide are not easily soluble in water, they will be adsorbed on the cathode plate. When the calcium carbonate and magnesium hydroxide on the cathode plate are deposited to a certain extent, the electrode working efficiency will be affected. In addition, a selectively permeable proton exchange membrane, i.e., a diaphragm, is often set between the anode and cathode. The ideal diaphragm material should have the characteristics of good ion conductivity, high porosity and low resistivity. However, during the use of the electrolytic water device, metal oxides, calcium carbonate and magnesium hydroxide generated near the cathode chamber will also adhere to the diaphragm. Therefore, the electrolytic water device will affect the effectiveness of the diaphragm after long-term use. Therefore, the electrolytic water device often needs to be disassembled, cleaned or even replaced after a period of use in order to continue to maintain the performance of the electrolytic water device, which greatly increases the use cost of the electrolytic water device and reduces the user's experience and desire to buy.

[0056] The applicant used an oxidation potential (liquid mV) detector to measure the oxidation potential of 5 groups of water electrolysis devices in different regions using tap water of different water qualities for 6 months (see Table 1).

[0057] Table 1. Changes in oxidation potential of water electrolysis devices after a period of use under water quality conditions in different regions

[0058]

[0059] Note: The results are obtained from three consecutive measurements.

[0060] It can be found from Table 1 that under the water quality conditions in different regions, the oxidation potential value of the electrolyzed water prepared by the electrolyzed water device dropped significantly after one month of use; after 4 months, due to water quality reasons in some areas, the oxidation potential value of the electrolyzed water prepared by the electrolyzed water device dropped below 400, which could not meet the functional requirements of sterilization and disinfection.

[0061] The applicant used an oxidation potential (liquid mV) detector to measure the oxidation potential of electrolyzed water at different spraying distances using 25°C raw water in the electrolysis water device (see Table 2).

[0062] Table 2. Oxidation potential of raw water at 25℃ and electrolyzed water at different spraying distances

[0063]

[0064] Note: The results are obtained from three consecutive measurements.

[0065] It can be found from Table 2 that the oxidation potential values ​​of the electrolyzed water measured at different spraying distances from the water outlet are very different. Specifically, the farther away from the water outlet, the more obvious the decrease in the oxidation potential value of the electrolyzed water.

[0066] The applicant used an oxidation potential (liquid mV) detector to measure the oxidation potential of electrolyzed water produced by the electrolysis device using 25°C raw water after being placed for 0s, 20s, 30s, and 40s (see Table 3).

[0067] Table 3. Oxidation potential of raw water at 25℃ and electrolyzed water after different storage time

[0068]

[0069] Note: The results are obtained from three consecutive measurements.

[0070] It can be found from Table 3 that the oxidation potential value of the prepared electrolyzed water decreases rapidly as the storage time increases, and even basically drops to less than 400 mV after 30 seconds.

[0071] From the above, it can be seen that the oxidation potential of the electrolyzed water prepared by the electrolytic water device changes significantly with the spraying distance and the placement time, and it is extremely difficult to accurately detect it; it is easy to have inaccurate detection problems due to factors such as the spraying distance or the detection time performance.

[0072] Therefore, the present application provides an electrolytic water detection device to solve the technical problem that users cannot promptly detect the decline in the biological function of the electrolytic water produced immediately after long-term use of the electrolytic water device. Figure 1 As shown, the water electrolysis device includes a raw water supply, an electrolytic cell 20 and an oxidation potential detection module 50. The raw water can be pure water, tap water, mineral water, weak acid or a neutral salt solution such as physiological saline. The electrolytic cell 20 includes an anode 21 and a cathode 22. The electrolytic cell 20 can be connected to the raw water supply, so that the raw water is transported to the electrolytic cell 20 and electrolyzed to prepare electrolyzed water with a high oxidation potential rich in hydroxyl radicals (·OH); the prepared electrolyzed water is discharged through the water outlet 40 and connected to the electrolytic cell 20 using the oxidation potential detection module 50, which can directly detect the oxidation potential value of the electrolyzed water prepared by the electrolytic cell 20. Through the above-mentioned setting, the true oxidation potential value of the electrolyzed water prepared at the electrolytic cell 20 can be directly measured to avoid the problem of inaccurate measurement of the prepared electrolyzed water due to the problem of transportation distance and time; and, through the setting of the oxidation potential detection module 50, it can avoid the problem of needing to collect electrolyzed water and cooperate with professional detection instruments and experimental means to detect its oxidation potential, thereby improving the user experience.

[0073] In one embodiment, the raw water supply part includes a water tank 10 provided in the water electrolysis device, and the water tank 10 is connected to the electrolytic cell 20. Pure water, tap water, mineral water, weak acid or neutral saline solution such as physiological saline is injected into the water tank 10 as raw water for preparing electrolyzed water, and the raw water is transported to the electrolytic cell for preparing electrolyzed water with a high oxidation potential. The design of the water electrolysis device with its own water tank especially meets the needs of the C-end customer market for miniaturization and portability of the water electrolysis device.

[0074] In other embodiments, the raw water supply member includes a pipeline (not shown) provided in the water electrolysis device, and the electrolytic cell 20 is connected to a water supply device for supplying raw water through the pipeline, and the water supply device is used to supply raw water to the electrolytic cell 10. The device structure design of this embodiment is particularly aimed at the demand for continuous or large-scale preparation of electrolyzed water, which requires a large amount of raw water supply, which cannot be met by the portable design of the electrolytic water device with a self-contained water tank.

[0075] In one embodiment, the electrolytic water device also includes an air pump 30, one end of which is connected to the electrolytic cell 20 and the other end is connected to the water outlet 40. When the air pump 30 is in operation, the negative pressure generated can quickly transport the raw water in the water tank or the external water supply equipment to the electrolytic cell 20 to prepare electrolytic water, and atomize the electrolytic water prepared by the electrolytic cell 20 and spray it through the water outlet 40. The form of electrolytic spray is more conducive to fully contacting the surface of the object to be disinfected or the surface of the user's skin, and can also save the use of raw water and electrolytic water, and extend the service life of the electrode. In addition, the air pump 30 is connected to the power supply 80 and the control circuit board 70 respectively, the power supply 70 is used to power the air pump 30, and the control circuit board 70 is used to control the operation of the air pump 30.

[0076] In other embodiments, the water electrolysis device may not be provided with an air pump. In this case, the position of the raw water supply part is higher than the electrolytic cell 20, and the position of the electrolytic cell 20 is higher than the water outlet 40. At this time, under the action of gravity, the raw water can also flow smoothly from the raw water supply part into the electrolytic cell 20 to be prepared into electrolyzed water, and then be smoothly discharged through the water outlet at a lower position. In this embodiment, no air pump is provided, which can save some power consumption accordingly.

[0077] In one embodiment, the water electrolysis device is provided with a water inlet (not shown in the figure) connected to the water tank 10, and the raw water is injected into the water tank 10 through the water inlet.

[0078] In other embodiments, the water tank 10 may also be configured to be detachable, and the water tank 10 may be removed and filled with raw water before being installed.

[0079] In one embodiment, the oxidation potential detection module 50 may be configured as a probe or a probe.

[0080] Further, such as Figure 2 As shown, the probe or probe can be placed on the anode 21 and the cathode 22 of the electrolytic cell 20 to simultaneously detect the oxidation potential values ​​of the anode 21 and the cathode 22 of the electrolytic cell 20 .

[0081] In other embodiments, the probe or probe can be set at the anode 21 or the cathode 22 of the electrolytic cell 20. It is placed on the anode 21 side to detect the positive oxidation potential, and an alarm is triggered when it is lower than a preset threshold value. For example, when the oxidation potential is 450mv detected on the anode 21 side, an alarm is triggered; when it is placed on the cathode 22 side to detect the negative oxidation potential, an alarm is triggered when its absolute value is lower than a preset threshold value. For example, when the oxidation potential is -450mv detected on the cathode 22 side, an alarm is triggered. For example, the preset threshold value can be set at 500mV.

[0082] The oxidation potential detection module 50 is placed on the anode 21 side or the cathode 22 side because the electrolyzed water product of the present application will produce a large number of active ions, especially hydroxyl radicals, which are produced during the electrode electrolysis process. Therefore, the closer the hydroxyl radicals are to the edge of the anode 21 and the higher the concentration, the more accurate the oxidation potential detection is. On the cathode 22 side, since oxidation-reduction reactions occur on the anode 21 and the cathode 22 respectively, wherein the anode 21 undergoes an oxidation reaction and the cathode 22 undergoes a reduction reaction, water can be reduced to hydrogen. Therefore, the cathode 22 detects a negative oxidation potential, which is to detect the degree of electrolysis from the degree of the reduction reaction, which represents the ability and efficiency of electrode electrolysis.

[0083] The relationship between the oxidation potentials of the anode 21 and the cathode 22 is further described. The oxidation-reduction potential of the electrolyzed water obtained by the anode 21 increases, such as: the oxidation potential of the oxidized water is expressed as a positive value, which can rise from +200mv (millivolts) to +1200mv (millivolts); the oxidation-reduction potential of the reduced water obtained by the cathode 22 gradually decreases, such as: the reduction potential of the reduced water is expressed as a negative value, which can gradually decrease from +200mv (millivolts) to -800mv (millivolts). The increase in the potential of the electrolyzed water indicates that the oxidation power is stronger; the decrease in the potential of the reduced water indicates that the reducing power is stronger.

[0084] In other embodiments, Figure 3 As shown, the probe or probe may also be arranged on the inner wall of the cover plate in the electrolytic cell 20, because the electrolyzed water does not leave the electrolytic cell 20 at this time, and the accuracy of the oxidation potential value of the electrolyzed water measured by it can be guaranteed.

[0085] In other embodiments, if an open electrolytic cell 20 is used, the oxidation potential detection module 50 may also be disposed on the inner side or bottom surface of the shell of the water electrolysis device and close to the electrolytic cell 20 to ensure the accuracy of the oxidation potential detection at the electrolytic cell 20 .

[0086] In other embodiments, the oxidation potential detection module 50 may be a detection circuit, and the oxidation potential value at the electrolytic cell 20 is detected by the detection circuit.

[0087] In other embodiments, the oxidation potential detection module 50 may also be a detection pen, and a contact electrically connected to the electrolytic cell 20 is provided on the surface of the water electrolysis device, and the oxidation potential value at the electrolytic cell 20 is obtained by contacting the detection pen with the contact.

[0088] In other embodiments, the detection pen serves as an oxidation potential detection module 50 and can detect the oxidation potential value at the water outlet 40 of the water electrolysis device.

[0089] In one embodiment, the anode 21 is made of conductive diamond particles; the cathode 22 is made of metal particles or conductive ceramic particles, wherein the metal particles include at least one of titanium, platinum, gold, titanium alloy, nickel, palladium, platinum-ruthenium alloy or stainless steel.

[0090] In other embodiments, both the anode 21 and the cathode 22 are made of conductive diamond particles.

[0091] In other embodiments, the anode 21 and the cathode 22 are both made of metal particles or conductive ceramic particles, wherein the metal particles include at least one of titanium, platinum, gold, titanium alloy, nickel, palladium, platinum-ruthenium alloy or stainless steel.

[0092] In one embodiment, the electrolytic cell 20 further includes a diaphragm 23, which is located between the anode 21 and the cathode 22. After long-term use, the diaphragm may also adhere to insoluble substances such as metal oxides, calcium carbonate, and magnesium hydroxide, thereby affecting the efficacy of the diaphragm.

[0093] Furthermore, the water electrolysis device further includes a control circuit board 70 and a power supply 80. The control circuit board 70 is electrically connected to the electrolytic cell 20 and the air pump 30, respectively, so as to control the operation of the electrolytic cell 20 and the air pump 30. The power supply 80 supplies power to the electrolytic cell 20, the air pump 30 and other structures to maintain their operation.

[0094] In one embodiment, the power source 80 is a dry cell battery or a rechargeable battery to improve the portability of the water electrolysis device.

[0095] In other embodiments, the power source is an external power source that needs to be plugged in.

[0096] In one embodiment, the water electrolysis device further includes a switch 60, which may be a touch panel or a mechanical button. The switch 60 may be used to connect or disconnect the electrical connection between the control circuit board 70 and the power supply; after injecting raw water into the water tank 10, the user only needs to touch or press the switch 60, and the water electrolysis device can start the electrolysis water preparation work.

[0097] Furthermore, the water electrolysis device also includes an oxidation potential reminder module, which is activated when the oxidation potential value of the electrolyzed water is lower than a preset threshold.

[0098] In one embodiment, the oxidation potential reminder module includes an indicator light 90, and the indicator light 90 and the oxidation potential detection module 50 are electrically connected to the control circuit board 70. The control circuit board 70 controls the color change of the indicator light 90 according to the oxidation potential value detected by the oxidation potential detection module 50. The user determines whether the electrolysis cell 20 of the water electrolysis device needs to be cleaned by observing the color of the indicator light 90.

[0099] In other embodiments, the oxidation potential reminder module includes a sound alarm unit. If the absolute value of the oxidation potential value detected by the oxidation potential detection module 50 is less than a preset threshold, the control circuit board 70 starts the sound alarm unit to issue a voice alarm, thereby reminding the user that the electrolytic cell 20 needs to be cleaned.

[0100] In other embodiments, the oxidation potential reminder module includes a vibration reminder unit. If the absolute value of the oxidation potential value detected by the oxidation potential detection module 50 is less than a preset threshold, the control circuit board 70 starts the vibration reminder unit to vibrate and alarm, thereby reminding the user that the electrolytic cell 20 needs to be cleaned.

[0101] In other embodiments, the water electrolysis device includes an oxidation potential value display module, which can be used to display the real-time numerical value of the oxidation potential value measured at the electrolytic cell 20 after being started; the user can actively choose whether to clean the electrolytic cell 20 by observing the displayed oxidation potential value.

[0102] In other embodiments, the water electrolysis device further includes a wireless connection module, and the oxidation potential value measured by the oxidation potential detection module 50 can be transmitted to the terminal electronic device through the wireless connection module, and the oxidation potential value at the electrolytic cell 20 can be viewed through a small program of a terminal electronic device such as a mobile phone. The electrolytic cell 20 can be cleaned by operating the water electrolysis device body; or a cleaning instruction can be sent to the water electrolysis device through a terminal electronic device such as a mobile phone to clean the electrolytic cell 20. The wireless connection module can be Bluetooth, wifi, NFC, etc.

[0103] In one embodiment, the water electrolysis device further includes a cleaning module (not shown in the figure), and the electrolytic cell 20 is cleaned by the cleaning module.

[0104] In other embodiments, the cleaning module includes a reversal circuit, which can be arranged at the shell of the electrolytic cell 20, and the reversal circuit is respectively connected to the anode 21 and the cathode 22 of the electrolytic cell 20 through wires, and the reversal circuit is also connected to the control circuit board 70 and the power supply. If the oxidation potential detection module 50 detects that the oxidation potential value at the electrolytic cell 20 is less than the preset threshold value or the user actively intends to clean the electrolytic cell 20, the user can inject the cleaning liquid (a weak acid solution can be selected) into the water tank 10, and use a terminal electronic device such as a mobile phone to issue a cleaning instruction or start the switch of the electrolytic water device (for example, set a long press or long touch switch as an instruction to start cleaning), so that the control circuit board 70 controls the operation of the reversal circuit, thereby cleaning the electrolytic cell 20, thereby removing the insoluble scale adhered to the cathode 22 and the diaphragm 23. After pickling, rinse with a large amount of clean water to complete the cleaning of the electrolytic water device. Compared with the existing strategy of directly replacing new electrodes, without disassembling the electrolytic cell 20 to replace the electrodes and diaphragms, the neutralization reaction effect of weak acid and alkaline scale on the surface of the electrodes and diaphragms is utilized to effectively remove the deposits covering the surfaces of the electrodes and diaphragms, and to achieve reactivation of the electrodes, thereby extending the use time of the electrodes, greatly improving the life of the electrodes, and improving the cost-effectiveness of the electrodes.

[0105] In other embodiments, the cleaning liquid is preferably an acidic solution with a pH value of ≤ 3.5. The cleaning liquid may be any one of acetic acid, hydrochloric acid, and sodium citrate, or a mixture of two or three of them in a certain proportion.

[0106] By adopting the inverted circuit method in the embodiment of the present application, a weak acid with a pH of 3 was used to clean three groups of water electrolysis devices using Qingdao tap water, Wahaha purified water, and Chunyue purified water as raw water for 5 minutes. The oxidation potential values ​​of the water electrolysis devices were detected before and after cleaning (self-tested by the oxidation potential detection module of the present application), and the results are shown in Table 4.

[0107] Table 4.3 Changes of electrolysis water devices with different raw water before and after cleaning

[0108] type Before cleaning After cleaning Tap water 470±10 810±10 Wowhahaha 490±10 830±10 Pure Joy 500±10 840±10

[0109] Note: The results are obtained from three consecutive measurements.

[0110] As can be seen from Table 4, the oxidation potential value of the electrolytic water device of the present application changes significantly before and after cleaning, and the cleaning effect is good. The oxidation potential value of the electrolytic water spray immediately prepared by the electrolytic water device after cleaning can achieve a sterilization and disinfection effect. The electrolytic water device can be recycled to maintain the commercial use value of the electrolytic water device, thereby improving the user experience and maintaining user stickiness.

[0111] In summary, after being used for a long time, the electrolytic water device of the present application can automatically and accurately detect the oxidation potential value at the electrolytic cell 20 of the device without professional experimental instruments and complex experimental means, thereby promptly and proactively reminding the user that the biological function of the electrolytic water device has declined and needs to be cleaned. Moreover, the electrolytic water device of the present application has its own cleaning module, which can remove the deposits covering the surface of the electrode and the diaphragm by injecting an acidic cleaning solution for a period of time in the electrolytic cell 20 without disassembly or replacement, and realize the reactivation of the electrode, thereby extending the use time of the electrode, greatly improving the life of the electrode, and improving the cost-effectiveness of the electrode.

[0112] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
