[0021] Figure 1 This is a schematic diagram of an embodiment of the ultraviolet disinfection machine of the utility model ①;

[0022] Figure 2 This is a schematic diagram of an embodiment of the ultraviolet disinfection machine of the utility model. DETAILED DESCRIPTION

[0023] The following is further described in detail through specific implementation methods:

[0024] 1. Definition

[0025] Atomizer: It can turn water and liquid medicine into fine aerosols, with the characteristics of large mist volume and small and uniform droplets.

[0026] Spraying: refers to the process of spraying liquid or gas in the form of spray onto the target surface through spraying equipment. Its working principle mainly includes the supply, pressurization and injection of liquid or gas.

[0027] Water pump: A machine that transports liquid or pressurizes liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid.

[0028] Wet curtain: also called water curtain, made of a special paper honeycomb structure material, it uses the physical phenomenon of "water evaporation absorbs heat" to achieve cooling. Specifically, when working, water flows from top to bottom under the action of gravity, forming a water film on the corrugated fiber surface of the wet curtain. At this time, the air flows quickly through the wet curtain, and the water in the water film absorbs the heat in the air and evaporates, taking away a lot of heat, thereby achieving the purpose of cooling. In addition, when the air passes through the wet curtain, harmful substances such as dust, odor, bacteria, etc. in the air are filtered out, and it also has the effect of purification and sterilization.

[0029] Plasma generator: The main working principle of the plasma generator is to increase the low voltage to positive high voltage and negative high voltage through a boost circuit, and use the positive high voltage and negative high voltage to ionize the air (mainly oxygen) to produce a large number of positive ions and negative ions. The number of negative ions is greater than the number of positive ions (the number of negative ions is approximately 1.5 times the number of positive ions).

[0030] Negative oxygen ion generator: a device that generates negative air ions. The device processes the input DC or AC power through the EMI processing circuit and the lightning protection circuit, and then upgrades it to AC high voltage through the pulse circuit, overvoltage current limiting, high and low voltage isolation and other lines, and then obtains pure DC negative high voltage after rectification and filtering by special grade electronic materials. The DC negative high voltage is connected to the release tip made of metal or carbon elements, and the DC high voltage at the tip is used to generate high corona, and a large number of electrons (e-) are released at high speed. Electrons cannot exist in the air for a long time (the lifetime of existing electrons is only at the ns level), and they will be immediately captured by oxygen molecules (O2) in the air, thereby generating negative air ions. Negatively charged negative ions are electrode-neutralized with positively charged smoke and dust floating in the air, causing them to settle naturally, which has the effect of refreshing the air and removing smoke and dust.

Each group of ultraviolet germicidal lamps includes a mounting lamp holder 14 and a lamp body 4. The lamp body 4 is located in the air duct section, and the mounting lamp holder 14 is installed on the second mounting partition 5. The plasma generator 12 and the negative oxygen ion generator 13 are installed on the second mounting partition 5. The fan 6 is located in the electrical installation section and is installed on the lower surface of the first mounting partition 7. In this embodiment, the central wavelength of each group of ultraviolet germicidal lamps is 253.7nm, the power is 25W, and the irradiation intensity should be no less than 170μW / cm 2 The disinfectant in the disinfectant receiving device 8 is alcohol (C2H5OH), hydrogen peroxide (H2O2) and hypochlorous acid (HClO) or the like.

[0035] An air duct is provided between the air inlet 2 and the air outlet 11. The air duct is bent and reciprocated in the air duct section of the walking device 1, and then passes through the electrical installation section and the medium outflow section and communicates with the air outlet 11. The ultraviolet lamp structure is located in the air duct. The air duct can be formed by setting a partition on the inner surface of the walking device and using the partition to guide the air, or by setting a ventilation duct.

[0036] A cooling and humidifying structure is also provided in the walking device 1, and the cooling and humidifying structure is located on the air duct. The cooling and humidifying structure includes a water tank and a spraying structure, and the spraying structure is connected to the water tank. The spraying structure includes a spraying pipe 15 arranged above the water tank and a spraying water pump 16 connected to the spraying pipe 15, and the spraying water pump 16 is located in the water storage section. A wet curtain 3 is provided between the spraying pipe 15 and the water tank, and the wet curtain 3 is perpendicular to the air duct, and the wet curtain 3 is arranged opposite to the air inlet 2.

To protect human health and prevent the spread of germs in complex scenarios.

[0038] The spray water pump 16 pumps the water out of the water tank and sends it to the spray pipe 15, which sprays it onto the wet curtain 3 below. After the fan 6 is running, the air enters from the air inlet 2 and blows onto the wet curtain 3, accelerating the evaporation of the water on the wet curtain 3 to turn it into steam to take away the heat. After passing through the wet curtain 3, the air is cooled and humidified, and the dust, odor, bacteria and other harmful substances in the air are filtered out. Then the air continues to flow along the air duct, passes through the ultraviolet sterilization lamp, and finally flows out from the air outlet 11. At the air outlet 11 of the fan 6, a cool breeze 3 to 8 degrees lower than the site can be generated. After testing, the cooling effect is most significant when the relative humidity is less than 50% and the water evaporation amount is large; in order to adapt to the use environment, the disinfection machine shell is made of 304 stainless steel, and other materials, such as plastic shell, can also be used. It has a beautiful appearance, is sturdy and durable, and is widely used in various sites to cool down and disinfect bacteria for dense personnel, with a sterilization rate of more than 99.5%.

[0039] In order to avoid the impact of the pungent smell of disinfectant on the crowd, the controller can be set to use ultraviolet rays, plasma and negative oxygen ions for disinfection during the day when there are more people, and the disinfectant spray can be turned on at night when there are no people.
