The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
As shown in fig. 1 to 5, an ozone water preparing apparatus comprises an anode sheet 3 for generating ozone, and a cathode sheet 2 for generating electrolysis with the anode sheet 3, wherein the anode sheet 3 is provided with a first anode power line 7, the cathode sheet 2 is provided with a first cathode power line 6, water flows through a gap between the anode sheet 3 and the cathode sheet 2 to generate ozone water, the ozone water preparing apparatus further comprises a middle electrode sheet 1 for removing precipitates on the surface of the cathode sheet 2, the middle electrode sheet 1 is arranged on one side of the cathode sheet 2 or the anode sheet 3, the middle electrode sheet 1 is provided with a second cathode power line 4, the cathode sheet 2 is further provided with a second anode power line 5, the first anode power line 7 and the first cathode power line 6 are conducted to form a loop in an electrolysis process, and the second cathode power line 4 and the second anode power line 5 are conducted to form a loop in the electrolysis process, the deposits on the surface of the cathode plate 2 automatically fall off after being communicated with the loop through the second cathode power line 4 and the second anode power line 5.
In the practical use process, because the anode sheet 3 is connected with a first anode power line 7 communicated with the anode of the power supply, and the cathode sheet 2 is connected with a first cathode power line 6 communicated with the cathode of the power supply, when the anode sheet 3 and the cathode sheet 2 are in a water body, and the first anode power line 7 is communicated with the first cathode power line 6 to form a loop, an electric field is generated between the anode sheet 3 and the cathode sheet 2, water molecules between the electric fields are electrolyzed and catalyzed into groups or molecules such as hydrogen, oxygen, ozone, free radicals and the like, but when the water source is common water, such as municipal tap water, river water, underground water and the like, the water often contains various charged ions, colloidal particles and other impurities, the impurities are easily adsorbed on the charged electrodes and subjected to redox reaction, particularly, compact precipitates can be formed on the surface of the cathode along with the increase of the working time and gradually thicken, and the precipitates can increase the circuit resistance, the proton exchange rate and the electrolysis efficiency are reduced, and the gap between the cathode sheet 2 and the anode sheet 3 may be blocked, increasing the risk of short circuit between the anode and the cathode. Therefore, a middle pole piece 1 is arranged between at least one side of the cathode piece 2 or the anode piece 3, a second cathode power line 4 connected with a power supply is arranged on the middle pole piece 1, a second anode power line 5 which is connected with the second cathode power line 4 and is also connected with the original cathode piece 2 is arranged on the original cathode piece 2, when the power supply between the anode piece 3 and the cathode piece 2 is closed, a current loop of the middle pole piece 1 and the original cathode piece 2 is conducted, the original cathode piece 2 is changed from a cathode to an anode, the interface environment between the original cathode piece 2 and sediment is changed by electrical exchange, the reduction interface is changed into an oxidation interface, chemical bonds are broken, the sediment is changed into loose after being oxidized and is easy to fall off quickly, and the production of the sediment on the surface of the cathode piece 2 can be obviously prevented by regularly switching the two power supply passages. In the practical application process, different settings can be carried out according to the working time ratio of the water quality to the two power supply paths, for example, the power supply paths are switched after the anode sheet 3 and the cathode sheet 2 work for 1-48h, the original cathode sheet 2 and the middle sheet 1 are conducted for 1-100 s, and then the power supply paths are switched to the original power supply paths, so that the power supply paths work repeatedly at regular time, the cathode sheet 2 can keep a clean state for a long time, the electrode structure and the working mode effectively solve the problem that the ozone preparation efficiency and the electrode service life are influenced by the deposits of the cathode sheet 2 in the existing ozone water preparation device, and the service life of the cathode sheet 2 is doubled.
