Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Further, such as Figure 2 As shown, a self-priming pump 6, an ozone generating device 10, a hydrogen peroxide generating device 9 and an ultraviolet device 11 are installed in the lower shell 1, the ozone generating device 10 and the hydrogen peroxide generating device 9 are arranged in parallel, and the inlet ends of the ozone generating device 10 and the hydrogen peroxide generating device 9 are commonly connected to the water outlet of the self-priming pump 6 through a first three-way elbow pipe 13, and the outlet ends of the ozone generating device 10 and the hydrogen peroxide generating device 9 are commonly connected to the inlet end of the ultraviolet device 11 through a second three-way elbow pipe 14. The water outlet of the self-priming pump 6 is connected with a one-way valve 7 and a pressure switch 8 in sequence, and the outlet end of the pressure switch 8 is connected to the inlet position of the first three-way elbow pipe 13, and the pressure switch 8 can provide an on-off signal for the main control board 16.

[0021] Further, such as Figure 2 As shown, the self-priming pump 6 is a micro self-priming pump. The flow rate of pure water drawn by the micro self-priming pump is controlled at 0.8L / min-1.2L / min, preferably 1.0L / min, so that the ozone concentration of the ozone-carrying water generated by the ozone generating device 10 is 1mg / L-2mg / L, which can be used directly.

[0022] Further, such as Figure 2 and Figure 3 As shown, the water inlet of the self-priming pump 6 is provided with a first internal joint 5, and the first internal joint 5 is connected to a first quick interface 3 extending from the side wall of the lower shell 1. The outlet end of the ultraviolet device 11 is provided with a second internal joint 12, and the second internal joint 12 is connected to a second quick interface 4 extending from the side wall of the lower shell 1. In order to facilitate carrying, the first quick interface 3 and the second quick interface 4 both adopt an external thread structure, and the first internal joint 5 and the second internal joint 12 are provided with corresponding internal thread structures, which cooperate with each other to achieve effective and quick installation and disassembly. 5 and the second internal joint 12 are both provided with limiting blocks, the inner wall of the lower shell 1 is provided with a limiting seat 15 for the limiting block to be inserted, and the inner top surface of the upper shell 2 is fixedly connected with a limiting plate 23 for resisting the first internal joint 5 and the second internal joint 12. The limiting seat 15 is used to limit the limiting block axially, and the limiting block is radially limited under the abutment action of the limiting plate 23. Therefore, when the upper shell 2 and the lower shell 1 are fixed to each other, the first internal joint 5 and the second internal joint 12 remain in position, thereby facilitating the subsequent connection of the first quick interface 3 and the second quick interface 4.

[0023] Further, such as Figure 2 and Figure 3 As shown, a battery, a main control board 16 and a low-power voltage regulator board 17 are also installed in the lower shell 1. The main control board 16 and the low-power voltage regulator board 17 are electrically connected to the battery, and a Type-C interface can be set on the surface of the lower shell 1. The Type-C interface is powered by a power supply within the human safety voltage range and can optionally use a fast pluggable power supply. Therefore, it is powered by an external power adapter or an internal battery. After the external power adapter is inserted into the Type-C interface or the battery is fully charged, a constant current can be provided to generate ozone and hydrogen peroxide, and the battery is preferably a lithium battery. A touch circuit board 20 is fixedly installed inside the upper shell 2, and the touch circuit board 20 is A display light is installed, and a touch switch 24 connected to a touch circuit board 20 is provided on the surface of the upper shell 2. By touching the touch switch 24, the display light can be driven to light up and a start signal can be given to the main control board 16, thereby driving the self-priming pump 6, the ozone generating device 10, the hydrogen peroxide generating device 9 and the ultraviolet device 11 to operate respectively, that is, the touch circuit board 20, the main control board 16, and the low-power voltage stabilizing board 17 constitute a control system, which has extremely low power consumption. According to a large number of experiments and test data, its power consumption in standby mode is as low as 0.1mA, which greatly prolongs the use time and service life of the lithium battery, thereby achieving energy saving and cost reduction.

[0024] Further, such as Figure 2As shown, the ultraviolet device 11 includes a static mixer and an ultraviolet lamp arranged on the static mixer and irradiating the solution passing through the static mixer with ultraviolet light. The static mixer can make the two solutions fully mixed. The ultraviolet lamp adopts a low-pressure mercury lamp with a wavelength of 254nm, which can meet the effective wavelength of ozone and hydrogen peroxide photolysis.

[0025] Photolysis of ozone: Under ultraviolet light (wavelength less than 310nm), ozone undergoes photolysis to generate oxygen and active oxygen atoms (O 1 D): O3+hv → O2+O ( 1 D); Active oxygen atoms react with water to generate hydroxyl radicals: O ( 1 D) +H2O → 2 ● OH; Photolysis of hydrogen peroxide: Under ultraviolet light (wavelength 254nm), it directly decomposes to generate two hydroxyl radicals: H2O2+hv → 2 ● OH; Therefore, when ozone and hydrogen peroxide exist at the same time and are irradiated with ultraviolet light, the generation of hydroxyl radicals increases significantly and the oxidizing capacity is greatly enhanced. That is, ultraviolet light promotes the photolysis of ozone and hydrogen peroxide, accelerates the generation of hydroxyl radicals, and improves production efficiency.

[0026] like Figure 1-Figure 3 As shown, a method for preparing dual electrolytic water based on O3 and H2O2 in parallel is applied to the device for preparing dual electrolytic water based on O3 and H2O2 in parallel as described above, comprising the following steps: S1. Pretreatment of water sources: remove impurities such as suspended particles and organic matter in water through sand filters and carbon filters, and use ion exchange equipment or reverse osmosis equipment to reduce water hardness and conductivity, prevent scaling and electrode contamination during the electrolysis process, so as to ensure that the water quality entering the system meets the process requirements and prevent adverse effects on equipment and reactions; S2, generating ozone and hydrogen peroxide, using a self-priming pump 6 to extract the treated water and transport it to the ozone generator 10 and the hydrogen peroxide generator 9 respectively, the ozone generator 10 generates hydroxyl radicals, ozone and hydrogen peroxide under the action of an electric field, and the hydrogen peroxide generator 9 generates hydrogen peroxide by electrochemical electrolysis; The ozone generating device 10 can use diamond conductive material as an electrolytic electrode, and apply a low-voltage electric field to the electrode of the diamond conductive layer to bombard pure water, so that hydrogen atoms and oxygen atoms in water molecules are displaced and ionized, and hydroxyl free radicals, hydrogen peroxide, ozone and other oxidizing substances and protective substances rich in active oxygen molecules are generated. The following main reactions occur in the pure water in the ozone generating device 10: Anode (main) reaction: M+H2O-e- → M(● OH)+H + ; (Side) reaction: 2M ( ● OH) → H2O2+2M; 4M( ● OH) → O2*+2H2O+4M; 6M( ● OH) → O3+3H2O+6M; Cathode reaction: 4H2O+4e- = 4OH-+2H2; M is diamond crystal material, O2* is excited oxygen molecule; The electrolytic reaction of the hydrogen peroxide generating device 9 is: O2+2H + +2e- → H2O2; In the electrolysis process, hydrogen ion filter membrane is used to selectively conduct hydrogen ions to prevent interference from other ions and improve the generation efficiency and purity of hydrogen peroxide; S3, mixing ozone and hydrogen peroxide, by controlling the output flow of the ozone generator 10 and the hydrogen peroxide generator 9, that is, adjusting the flow of the two solutions by means of a flow meter and a control valve, etc., delivering the internal solutions of the two to the ultraviolet device 11 according to the mass ratio of hydrogen peroxide and ozone, and fully mixing the two solutions by means of a static mixer, that is, adding hydrogen peroxide to ozone can further promote the generation of hydroxyl radicals, wherein if the generation of hydroxyl radicals is to be maximized, the mass ratio of hydrogen peroxide to ozone is controlled to be between 0.35 and 0.45, because 0.5 moles of hydrogen peroxide are required for each 1 mole of ozone to generate hydroxyl radicals by bending reaction, and if only the hydroxyl radicals in the ozone aqueous solution are to be increased, the mass ratio of hydrogen peroxide to ozone is controlled to be below 0.35; S4, UV light irradiation, using ultraviolet light to irradiate the mixed solution to promote the photolysis of ozone and hydrogen peroxide, further promote the generation of hydroxyl free radicals, thereby significantly enhancing the oxidizing capacity of the aqueous solution. Compared with a simple ozone aqueous solution, this high-concentration hydroxyl free radical disinfectant has a better effect in sterilization and disinfection; S5. Collection and application: the solution after UV light irradiation can be directly collected for sterilization and disinfection. It can be used as soon as it is made and is suitable for medical care, food processing, agricultural irrigation and other fields.

[0027] Under experimental conditions, a comparative test of the sterilization effect of the disinfectant of the present invention and the traditional ozone aqueous solution was conducted: Table 1: The test strain is Escherichia coli, and the killing rate is calculated as (positive control sample colony count - test sample colony count) * 100% / positive control sample colony count

[0028] Table 2: Results of bactericidal test against Porphyromonas gingivalis

[0029] Table 3: Results of bactericidal test against Prevotella In summary, it can be seen from Table 1 that, in the same and shorter time, this product has a significant effect of killing Escherichia coli compared with traditional ozone aqueous solution; it can be seen from Table 2 that this product has a strong bactericidal effect on Porphyromonas gingivalis; it can be seen from Table 3 that this product has a strong bactericidal effect on Prevotella; therefore, this product can achieve a bactericidal rate of 99.999% for microorganisms such as Escherichia coli, which is a certain improvement over the existing bactericidal effect of using ozone aqueous solution alone, and the contact time required for this product to achieve the same bactericidal effect is shorter.

[0030] In addition, the main products after the reaction are water and oxygen, with no harmful chemical residues, which is safe and environmentally friendly.

[0031] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
