Abstract
Description
Technical Field
[0001] This utility model relates to the field of disinfection equipment, and in particular to an ozone water mixing spray device. Background Technology
[0002] Ozone is a strong oxidizing bactericide, and using ozone to disinfect object surfaces is a common method of sterilization. According to my country's ozone disinfection technical specifications for surface disinfection, the ozone concentration should be ≥60 mg / L, the relative humidity ≥77%, and the contact time 60 to 120 minutes. For ozone water disinfection, the requirements are: an ozone concentration ≥10 mg / L in the water and a contact time ≥60 minutes.
[0003] Comparison shows that ozone in water has a stronger bactericidal effect and requires less time. This is because, in a humid environment, the cell membranes of microorganisms on the surface of objects swell and thin due to moisture absorption. In this state, the cell membranes are more easily penetrated by ozone. Ozone can quickly react with the unsaturated fatty acids in the cell membrane, changing its structure and function, causing leakage of cell contents, thereby enhancing the bactericidal effect. Not all objects can be disinfected with ozone water. To enhance the disinfection effect, ozone water mist has become a more widely applicable method. Because ozone water particles are very small, they float in the environment as a mist, allowing them to adhere to the disinfection target without any blind spots. The smaller the water mist particles, the better the floating effect. When the particle diameter is less than 100 micrometers, it is called ozone dry fog. The common method for producing ozone dry fog is to dissolve ozone in water, then pressurize the ozone water and spray it out as ozone dry fog through a fluid nozzle. Alternatively, ozone water can be sprayed through a two-fluid nozzle and high-pressure air can be used to form a better ozone dry fog. However, due to the simple structure of this type of ozone water dry fog generating device, the disinfection effect of the ozone dry fog cannot be fully guaranteed. Utility Model Content

[0015] The present invention will be further described in detail below with reference to the accompanying drawings.
[0016] Example: An ozone-water mixing spray device, such as Figure 1 As shown, the device includes a main body 1 and a control panel 2 mounted on the main body 1. Users operate the main body 1 via the control panel 2. The main body 1 contains a processing chamber 3, which houses an oxygen generator 4, an ozone generator 5 connected to the oxygen generator 4, and a channel mixer 6. The oxygen generator 4 includes an air compressor 7, an air purifier 8, a PSA pressure swing adsorption oxygen generator 9, and an oxygen storage tank 10, connected in sequence. Air is continuously supplied through the air compressor 7, purified by the purifier, and then fed into the PSA pressure swing adsorption oxygen generator 9 to obtain pure oxygen, which is stored in the oxygen storage tank 10.
[0017] Oxygen produced by oxygen generator 4 is used to supply ozone generator 5 to produce ozone gas. The generated ozone is then transported to channel mixer 6. Channel mixer 6 has a through-flow channel with a Venturi tube structure. One end of channel mixer 6 is connected to air compressor 7, which continuously inputs pressurized airflow under operator control. Ozone inlet 11 is located in the middle of channel mixer 6 and is connected to ozone generator 5, allowing ozone gas to mix with the airflow. During ozone mixing, due to the special Venturi tube design of the through-flow channel, the high-pressure air is compressed at the throat, causing a sharp increase in velocity and a decrease in pressure to negative pressure, drawing ozone gas into the high-speed airflow for thorough mixing.
[0018] The other end of the channel mixer 6 is connected to an airflow duct 12, through which the initially mixed ozone gas is transported. To fully ensure the disinfection effect of the final output ozone mixed dry fog, a mixing injector 13 is also connected in the treatment chamber 3. The mixing injector 13 has a spray chamber 14 in the middle, and a narrow slit nozzle 15 is provided at one end of the spray chamber 14. The end of the spray chamber 14 away from the narrow slit nozzle 15 is connected to the airflow duct 12. The mixed high-speed ozone gas flow enters the spray chamber 14 along the airflow duct 12 and is sprayed out from the narrow slit nozzle 15.
[0019] Meanwhile, the mixing injector 13 is also equipped with an ozone water inlet 16, and the ozone gas undergoes secondary mixing before being ejected. The processing chamber 3 also contains an ozone water mixing chamber 17, and a water storage tank 18. The ozone water mixing chamber 17 is connected to both the water storage tank 18 and the ozone generator 5. A water pump block 19 is also installed on the ozone water mixing chamber 17, and a guide hose 20 is provided between the water pump block 19 and the ozone water inlet 16. Under the operator's control, the ozone water mixture is input into the injection chamber 14 via the water pump block 19 and mixed with the high-speed airflow before being ejected. During this process, according to Henry's Law, at a certain temperature, the solubility of a gas in a liquid is directly proportional to the partial pressure of that gas; that is, the higher the pressure, the more gas is dissolved. The ozone mixture is under high pressure. When inhaled, the ozone water rapidly cuts and dissolves the mixture. As it is sprayed through the nozzle, the high-speed gas further cuts the mixture, forming fine droplets containing dissolved ozone. This ensures the sprayed dry fog consists of tiny water droplets with a diameter of 10 to 50 micrometers, effectively achieving contact disinfection of the surface of the object to be disinfected. Simultaneously, the sprayed ozone water dry fog is surrounded by gas containing a large amount of ozone, creating a disinfection environment where the ozone dry fog and ozone gas mix. During the compression and spraying of the ozone water, some ozone gas is released from the water, while some dissolves back into the water, ensuring a fully reliable ozone disinfection environment.
[0020] Considering the need for large-scale disinfection in actual use, the device body 1 has a limiting slot 21 on its side for the mixing sprayer 13 to be moved and placed. The treatment chamber 3 has rewinding wheels 24 for the guide hose 20 and airflow duct 12 to be wound and unwound, facilitating long-distance disinfection by the user. The rewinding wheels 24 automatically unwind, carrying the mixing sprayer 13 to the designated location for disinfection. The ozone water inlet 16 is equipped with a quick connector 22, and the guide hose 20 has a quick-connect sleeve 23 that mates with the quick connector 22, allowing for simultaneous adjustment of the guide hose 20 and the mixing sprayer 13, making assembly and disassembly convenient. Additionally, a plug block 25 is provided on the side of the device body 1 for the quick-connect sleeve 23 on the guide hose 20 to be movably engaged with it. This ensures that when the guide hose 20 is disassembled, it remains engaged with the plug block 25, limiting the entry of impurities and preventing the escape of ozone gas. The processing chamber 3 is also equipped with a leakage monitoring block 26, which can monitor the environment inside the processing chamber 3 and promptly report to the operators in case of leakage, ensuring the overall safe and reliable operation of the device.
[0021] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
