DETAILED DESCRIPTION

[0019] A multifunctional cooling fan, which is in the shape of a three-dimensional square and less than 1.5 meters in height, is used for ventilation and cooling in summer, and comprises a bottom water tank 1, a middle fuselage 2, a top cover 3, a controller 4, an air outlet 5, an exhaust fan 6, a rear ventilation wet curtain 72 device 7, a water pump 8, and a water supply pipe 9. The interior of the middle fuselage 2 is a machine cavity 101, and the exhaust fan 6 and the water pump 8 are connected to the controller 4 through wires; the water pump 8 is direct current, with a power of 5V to 10V; the exhaust fan 6 is a direct current exhaust fan 6 or an alternating current exhaust fan 6; movable casters are installed at the four corners of the bottom of the bottom water tank 1 to facilitate the movement of the machine; the top box opening of the bottom water tank 1 is connected to the bottom of the middle fuselage 2 through a screw assembly, the top of the middle fuselage 2 is fixedly connected to the top cover 3 through a screw assembly, and the top of the top cover 3 is fixedly connected to the controller through a screw assembly 4; an air outlet 5 is provided on the front of the middle fuselage 2, and a blade for adjusting the air direction is connected to the air outlet 5; a rear ventilation wet curtain 72 device 7 is provided on the rear wall of the middle fuselage 2, and the rear ventilation wet curtain 72 device 7 is used for water wetting ventilation evaporative cooling; a water pump 8 is placed in the bottom water tank 1, and the water pump 8 is connected to the bottom end of the water supply pipe 9, and the top end of the water supply pipe 9 is connected to the top of the rear ventilation wet curtain 72 device 7, and the exhaust fan 6 is fixed to the inner machine cavity 101 wall of the middle fuselage 2 by a screw assembly, and the air supply port of the exhaust fan 6 is aligned with the air outlet 5, and the water supply pipe 9 is arranged inside the machine cavity 101. The above structure belongs to the basic structure of the prior art product, and the main technical improvement of this product is: an ozone generator 10 is placed at the bottom of the bottom water tank 1, and the ozone generator 10 is connected to the controller 4 through an electric wire;

[0020] When in use, add an appropriate amount of water to the bottom water tank 1; then start the operation of the exhaust fan 6 and the water pump 8 by operating the controller 4. When the exhaust fan 6 is working, the wind enters from the rear ventilation wet curtain 72 device 7, passes through the machine cavity 101 and then enters the exhaust fan 6, and the exhaust fan 6 sends the wind out from the air outlet 5 to cool the human body in summer; when the water pump 8 is working, water is pumped to the top of the rear ventilation wet curtain 72 device 7 through the water supply pipe 9, and the water then falls from the wet curtain of the rear ventilation wet curtain 72 device 7 and wets the wet curtain, and the remaining water flows back to the bottom water tank 1 from the bottom of the rear ventilation wet curtain 72 device 7, and the water circulates in this way. During the circulation process, the wind contacts the water in the wet curtain, and the water evaporates, cooling the wind / air, together with the wind The ozone generator 10 flows away together, and the wind blown out is lower than the normal temperature, thereby playing a cooling role; the ozone generator 10 is started by operating the controller 4. After starting, the ozone generator 10 generates ozone and mixes with water. The ozone can quickly and efficiently sterilize the water in the water tank and can kill pathogenic viruses, bacteria and microorganisms; the extremely strong oxidizing property of ozone can destroy the biological structure of bacteria and viruses. Compared with harmful fungicides such as chlorine, bleaching powder and potassium permanganate, ozone is harmless to the human body; at the same time, ozone can also disinfect, deodorize and remove peculiar smell of the water in the water tank, so that the water quality in the water tank is better and cleaner. After the water is recycled and evaporated, the wind blown out is fresher and easier to use.

[0021] The bottom water tank 1 is manually filled with water. At the beginning, more water will be added. During the ventilation and cooling work, the rear ventilation wet curtain 72 device 7 will evaporate water, the water volume will gradually decrease, and the water level of the bottom water tank 1 will decrease; if the working power of the ozone generator 10 is fixed, when the water volume in the bottom water tank 1 is large, the ozone volume may be insufficient, affecting the sterilization, disinfection, deodorization and deodorization effects; when the water volume in the bottom water tank 1 is small, the ozone volume may be too much, and the ozone will affect the taste of the water. If the ozone in the water is too concentrated, the air quality is not comfortable enough; for this reason, a water level sensor 12 and / or an ozone sensor 13 are installed to control the amount of ozone generated;

[0022] The inner bottom wall of the middle fuselage 2 is fixedly connected with a water level sensor 12 by screws. The water level sensor 12 is used to detect the water level of the water tank. The water level sensor 12 is connected to the controller 4 through an electric wire; the controller 4 controls the working power of the ozone generator 10 by feedback of the water level through the water level sensor 12; when the water level of the water tank is full, more ozone is needed to have a better sterilization, disinfection, deodorization and deodorization effect on the water; when the water level of the water tank is lower, the amount of ozone should be reduced to control the appropriate amount of ozone generated; if there is less water and more ozone, the ozone smell of the water is too strong, and after the water is recycled and evaporated, the wind blown out carries too strong ozone smell, which makes people feel uncomfortable after breathing; therefore, the amount of ozone generated should be controlled by controlling the working power of the ozone generator 10. The lower the power, the less the amount of ozone generated, and the higher the power, the higher the amount of ozone generated. It is more important to control the appropriate amount of ozone generated.

[0023] An ozone sensor 13 is placed at the bottom of the bottom water tank 1. The ozone sensor 13 is used to detect the ozone content value of the water body. The ozone sensor 13 is connected to the controller 4 through an electric wire; the controller 4 controls the working power of the ozone generator 10 by feeding back the ozone content value through the ozone sensor 13; during production, the manufacturer sets the ozone content value through the controller 4. When the water level of the water tank is full, the power of the ozone generator 10 is increased to generate more ozone to reach the preset ozone content value; after the water level drops, the power of the ozone generator 10 is reduced through the controller 4 to reduce the generation of ozone to maintain the preset ozone content value;

[0024] Controlling the appropriate amount of ozone generated can be achieved through the water level sensor 12 or the ozone sensor 13, either of which can be selected; the ozone sensor 13 and the water level sensor 12 can also be installed and used at the same time to control the amount of ozone generated more accurately; so that the evaporated water can reduce bacteria and viruses as much as possible.

[0025] The back of the housing of the exhaust fan 6 is fixed with an ultraviolet germicidal lamp 14 by a screw assembly. The ultraviolet germicidal lamp 14 faces the rear ventilation wet curtain device. The ultraviolet germicidal lamp 14 is installed inside the machine cavity 101. It will not shine outward during operation and will not affect the use. The ultraviolet germicidal lamp 14 is connected to the controller 4 through an electric wire; the ultraviolet germicidal lamp 14 is used to sterilize and disinfect the circulating air, so that the air can reduce bacteria and viruses as much as possible, and improve the sterilization and disinfection effect together with the ozone generator 10;

[0026] This product is particularly suitable for use in public places such as hospitals, restaurants, and canteens. For families with infants and young children, it can sterilize and disinfect the air, improve air quality, reduce the spread of bacteria and viruses, and reduce the contact between infants and young children and bacteria, which is more conducive to their healthy growth.
