Technical Field

[0001] The utility model relates to an ozone water machine, in particular to an ozone water machine which adopts a circulating water supply method, and belongs to the technical field of ozone application. Background Art

[0002] With the continuous development of ozone production technology and application technology, various ozone products have been widely used in various fields of people's lives. In recent years, due to the restrictions on the application of gaseous ozone in certain fields, ozone water machines that can directly produce ozone water have come into being. Ozone water machines are equipment that converts the ozone gas generated by an ozone generator into ozone water through a gas dosing device and a gas-liquid mixing device. The ozone water produced by it can be used in many fields as an important tool for sterilization and disinfection.

[0003] After technical and market research, it is found that the ozone water machines on the market generally have the following shortcomings: First, the main production process of existing ozone water machines is imperfect, the ozone gas concentration is low, and the effects of ozone addition and gas-liquid mixing are poor, resulting in low concentration and unstable ozone water produced, which cannot meet the needs of users; second, the existing ozone water machines are large in size, not compact in structure, inflexible in use, and poor in equipment stability; third, the existing ozone water machines all have single-point water supply. Since ozone decays very quickly in water, it is difficult for users at the end of the pipeline network to ensure the stability of the concentration of the ozone water obtained.

[0004] CN200920239304 discloses an ozone water machine, which improves the above-mentioned shortcomings of the ozone water machine to a certain extent, but still has the problems of low gas-liquid mixing efficiency and unstable ozone concentration at the user's water use point. Summary of the invention

[0005] The purpose of the utility model is to provide an ozone water machine with a circulating water supply method in view of the above-mentioned deficiencies existing in the ozone water machine in the prior art, to increase the gas-liquid mixing efficiency in the ozone water machine and to improve the concentration of the ozone water at the end of the user's water use so as to meet the needs of the user by improving the structure of the gas-liquid mixing device and the water supply pipeline of the ozone water machine.

[0006] In order to solve the above technical problems, the utility model adopts the following technical scheme: an ozone water machine adopting a circulating water supply method, including a water inlet pipe, a water inlet valve, a water inlet pressure gauge, a mixing tank, a mixing tank outlet pipe, a dissolved air pump water inlet regulating valve, a dissolved air pump water inlet pressure gauge, a dissolved air pump, a dissolved air pump drain pipe, a dissolved air pump drain pressure gauge, an ozone pipe, a gas check valve, a water supply pump, a water supply pipe, a water supply pressure gauge, a sampling pipe, a sampling regulating valve, an online ozone water concentration detector, a reflux pipe, a reflux pressure gauge, a water supply check valve, an automatic exhaust valve, a user water intake interface, and an ozone gas generating and controlling device.

[0017] An air pump is used as a gas-liquid mixing device.

[0018] The mixing tank, the mixing tank outlet pipe, the water supply pump, the water supply pipe, the return pipe and the water supply check valve form a closed, one-way ozone water flow loop, and the water supply pump provides the circulation power.

[0019] The ozone gas generating and controlling device reads the detection value of the online ozone water concentration detector in real time, and adjusts the power of the ozone gas generating device according to the ozone water concentration value set by the user by using its internal control algorithm, so as to achieve the regulation and control of the ozone water concentration.

[0020] Compared with the prior art, the advantages and positive effects of the utility model are: 1. The air dissolving pump is used as the gas-liquid mixing device, which improves the gas-liquid mixing efficiency and increases the concentration of ozone water.

[0021] 2. The water supply method of the circulating pipeline is adopted to ensure that the user's water intake point can still quickly obtain ozone water with relatively stable concentration even if it is far away from the ozone water machine.

[0022] 3. By setting up the PLC control system, users can selectively set the ozone water outlet concentration. The PLC control system automatically adjusts the dosage of ozone gas according to the user's set value and the detection value of the online concentration meter, realizes automatic control of the ozone water machine and its output ozone water concentration, and ensures stable operation of the equipment.
