[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0020] Please refer to Figures 1 to 3 together. Now, the ozone generator provided by the present utility model will be described. The ozone generator includes a water tank 5, a low-voltage electrolysis module 3 and an ozone collection bottle 4; the cathode electrolysis assembly and the anode electrolysis assembly of the low-voltage electrolysis module 3 are both connected to the deionized water in the water tank 5 through pipelines; the ozone collection bottle 4 collects the ozone produced by the anode electrolysis assembly of the low-voltage electrolysis module 3 through an ozone collection pipe; a pressure regulating pipe 16 for air to enter is provided on the ozone collection pipe, and a vacuum filter 6 for purifying air is provided on the pressure regulating pipe 16.
[0021] The beneficial effects of the ozone generator provided by the present utility model are as follows: (1) Using the PEM electrolysis method, with deionized water as the raw material and solid precious metal polymer as the electrolyte, combined with the cation exchange mode, ozone is generated by the cation exchange and proton exchange separation of water molecules under the state of low voltage and high density current, without any auxiliary materials and additives. The generated ozone concentration can be as high as 20% (gas weight ratio 250-280 mg / L). The accompanying substances of the generated ozone gas are oxygen, without any secondary pollution and without nitrogen oxides (Nox); (2) The outside air enters the vacuum filter 6 through the air inlet 19, and the clean air filtered by the vacuum filter 6 is merged into the ozone outlet, which can adjust the ozone outlet pressure, avoid the fluctuation of the ozone outlet pressure, and ensure the stability of the ozone outlet pressure, thereby facilitating the stability of water quality disinfection and sterilization.
[0022] The working principle of the low-voltage electrolysis module 3 for electrolyzing ozone to produce ozone is as follows: Using deionized water to make water molecules undergo cation exchange and proton exchange separation to generate ozone under the state of low voltage and high density current; during operation, the positive and negative electrodes of the solid membrane electrode are conductively connected by low-voltage direct current to electrolyze deionized water. Water is separated into hydrogen and oxygen molecules in the form of proton exchange at the special anode solution interface. Hydrogen is directly discharged from the cathode solution interface, and oxygen molecules obtain energy due to the electron excitation generated by the high density current at the anode interface and polymerize into ozone molecules. For example, hydrogen is directly discharged from Figure 3 the waste gas outlet 17 shown in, or collected for utilization. Figure 3 In, the part inside the dotted line is the ozone generator part, the right side is the external pipeline, the part with arrows is the disinfection circulation pipeline, and the arrow direction represents the water flow direction.
[0023] The principle of generating ozone by electrolyzing water is mainly based on the chemical properties of ozone and the physical properties of electrolyzed water, involving the decomposition of water molecules under the action of an electric field during electrolysis and further oxidation reactions. During electrolysis, the low-voltage electrolysis module 3 is connected to the power supply module 9, and an electric current is passed through the water in the electrolytic cell through an electrolyte. The water molecules are decomposed into oxygen and hydrogen under the action of the electrolysis field. Among the gases generated by the anodic oxidation reaction, the oxygen molecules undergo an anodic oxidation reaction under the action of the electrode plate to generate ozone gas. The ozone gas is collected by the ozone collection bottle 4 and then transported to the water body that needs to be disinfected or oxidized.
[0024] The ozone generator provided by the present utility model is applicable to the disinfection of drinking water: deep well water, municipal water supply, secondary pressurized water supply, rural drinking water, etc.
[0025] In some embodiments, as Figure 3 shown, a regulating valve 15 is provided on the pressure regulating pipe 16 to adjust the amount of clean air transported by the vacuum filter 6 in real time through the regulating valve 15, and the ozone entering the ozone collection bottle 4 is cut off through the regulating valve 15. When the ozone gas directly participates in the reaction by mixing with the water quality, the mixing ratio with the water quality can be adjusted through the regulating valve 15. Among them, the pressure regulating pipe 16 can be a silicone tube or a PVC tube.
[0026] See Figure 1 and Figure 2 shown, the ozone generator provided by the present utility model further includes a box body 1. The box body 1 is a cuboid. A bottom partition 11 and an upper partition 14 are arranged inside the box body 1, and the box body 1 is divided into three parts: an upper compartment, a middle compartment 13, and a bottom compartment 2; the low-voltage electrolysis module 3 is arranged in the bottom compartment 2; the water tank 5 and the ozone collection bottle 4 are supported on the bottom partition 11 and are located in the middle compartment 13; the vacuum filter 6 is arranged in the middle compartment 13; the upper compartment is provided with a control circuit board 10 and a power supply module 9. An ammeter 7 and control buttons are arranged on the front side of the upper compartment, and a fan 8 is arranged on the side. By arranging each component in layers and integrating them into the box body, the convenience after intensification is reflected; among them, the power supply module 9, the ammeter 7, the control buttons, the fan 8, and the low-voltage electrolysis module 3 are all connected to the control circuit board 10.

The ozone collection bottles 4 store deionized water, filter the produced ozone with the deionized water, and temporarily store ozone gas. The three ozone collection bottles 4 can be connected in parallel or independently without being interconnected. When one of the ozone collection bottles 4 is full, the collection of another bottle is carried out.
[0032] In some embodiments, as Figure 1 and Figure 2 shown, there are clamps 12 connected to each other between the three ozone collection bottles 4, which play a role in fixing the ozone collection bottles 4.
[0033] In some embodiments, as Figure 3 shown, a drain pipe 18 is provided at the bottom of the water tank 5, and a water inlet pipe and a liquid level gauge are provided at the top.
