[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] Please refer to Figures 1-4 The utility model provides a technical scheme:

[0023] The device structure based on electrolysis principle is relatively simple, does not need huge and complex discharge equipment and supporting high-voltage power supply system, for example, using the household small ozone generator, using this direct electrolysis water technology, cooperating with small and exquisite electrode module and simple control circuit, can be conveniently integrated into kitchen small household appliance, air purifier and other equipment, provides ozone disinfection, air purification, drinking water sterilization and other functions for home environment, meets daily healthy life demand, and the land space is small, easy to operate and maintain;

[0024] As Figure 1 Shown, the whole micro ozone electrode module adopts the structure of inserting each other, can be directly fixed at the top of the container needing ozone generation, and the corresponding electrode plate is immersed in the aqueous solution, and the generated ozone can directly separate from the gap between the electrode plates;

[0025] The cathode plate 11 is fixed symmetrically on the ozone generator bottom cover 1, and the anode plate 10 is fixed between the two cathode plates 11, as shown in Figure 3 The electrode arrangement of two cathodes and one anode can effectively disperse the current density in the electrochemical system, so that the electric field lines form more symmetrical and uniform distribution between the electrodes, and then the ion concentration gradient is gently, especially the local enrichment degree of scale forming ions such as calcium and magnesium is significantly reduced;

[0026] At the same time, multiple cathodes in parallel can share the hydrogen evolution load of single pole, inhibit the sharp rise of pH value in the local area of cathode, thereby reducing the rapid deposition of scale products such as calcium carbonate and magnesium hydroxide, in addition, the intermediate anode or the centrally arranged anode will produce active oxygen and other self-cleaning factors under high potential conditions, which has a certain oxidative decomposition effect on microorganisms or organic adhesion, combined with the corrosion resistance of the coated titanium anode and the "self-cleaning" effect, can further reduce the deposition on the surface of the electrode;

[0027] In addition, the sandwich structure of cathode-anode-cathode has better fluid channel and mass transfer efficiency, reduces the probability of dead zone and turbulent extreme area, reduces the adhesion of initial crystalline particles on the electrode surface, and improves the stability and durability of the overall electrolysis reaction. Therefore, the two-cathode-one-anode layout can play a significant role in suppressing fouling, dispersing current load, improving electrode life, and maintaining the activity of the coated titanium anode, and is the preferred solution for anti-fouling design in water treatment and clean disinfection modules.

[0028] In addition, it can save the overall ozone generation module area, facilitate subsequent household appliance shell assembly installation, and similar products have household scrubbers, which can sterilize and disinfect the roller after scrubbing, such as Figure 4 As shown, the distance between the cathode plate 11 and the anode plate is usually controlled between 0.8mm-2mm, so that the generated bubbles can be effectively discharged, and at the same time, the distance between the plates is greatly reduced. Under the same voltage, the current will be greater, thereby accelerating the electrolysis reaction, and at the same time, the shortening of the mass transfer distance can also improve the reaction efficiency. The test voltage interval of the plate is usually controlled between 6-24V, and the current density is controlled between 5-50mA / cm 2 The ozone concentration generated by the micro product is generally greater than 0.3mg / L, and the overall electrode service life is controlled between 300-500h;

[0029] For the installation of the entire anode and cathode plate 10, the entire micro ozone electrode module can also be modified, such as other sandwich structures with three cathodes and two anodes, but it should be noted that the installation of the plate must be on the anode plate 10 side. The cathode plate 11 is installed to ensure that both sides of the anode plate 10 can be fully used;

[0030] The ozone generator bottom cover 1 and the ozone generator top cover 2 are installed in the shell with a circuit board 5. The cathode contact 4 and the anode contact 3 are fixedly connected to the ozone generator top cover 2, and the two are penetrated through the ozone generator top cover 2 and abutted with the circuit board 5. The cathode plate 11 and the anode plate 10 installed at the bottom of the ozone generator bottom cover 1 abut with the two side guide rings 7, that is, the cathode contact 4 and the cathode plate 11, and the anode contact 3 and the anode plate 10 are connected, so as to avoid the leakage of the generated ozone along the entire shell joint gap. The sealing ring 9 is installed at the connection position between the ozone generator bottom cover 1 and the outer shell, and the sealing ring 8 is installed on the cathode contact 4 and the anode contact 3.

[0031] For the convenience of the subsequent user to understand the whole electrolytic disinfection, the bottom of the whole circuit board 5 is also installed with LED lamp plate 6, through the irradiation mode, clearly understand the bubble generated between the electrode plate, because the electrolytic water produces ozone to the electrode plate material requirement is higher, this side adopts the material with high catalytic activity and conductivity corrosion resistance, common have noble metal and its oxide, boron-doped diamond, antimony-doped tin oxide, or other high-performance oxide materials, often used as such electrode material, and coated on the titanium substrate above-mentioned metal or its oxide coating, not only inherits the excellent mechanical properties of titanium, and greatly improves the electrochemical activity of the electrode surface, so that the current can be evenly and efficiently distributed on the electrode surface, for the electrolytic water ozone provides stable electronic supply.
