[0039] When the main motor 11 is started, it provides power for the entire system. The main motor is used to provide power for the refrigeration device 12 to ensure that it can operate. The refrigeration device 12 starts working, and the temperature sensor 15 measures to ensure that the temperature in the mist outlet pipe 13 reaches 20±1°C. When the temperature in the mist outlet pipe 13 reaches the set temperature, the high-voltage and high-frequency power supply in the driving power module 5 works, and the multi-layer micro-spacing discharge generating device 14 is started. At this time, the air in the mist outlet pipe 13 passes through the multi-layer micro-spacing discharge generating device 14, and under the action of the input high voltage, it is coupled to the discharge gap through the dielectric capacitor to form a strong electric field. Charged particles such as electrons gain energy under the action of the electric field, and react with the surrounding air molecules (such as oxygen molecules, nitrogen molecules, etc.) by inelastic collisions, ionization, etc., and transfer the electric field energy to the gas molecules in the air. As the level of excited gas molecules continues to increase, electron avalanches are triggered, forming space charges and strengthening the local electric field formed. The charges and electrons in the electric field form electric field waves. Since the charges move faster than the electrons, a conductive channel is formed, and a large number of fine pulse streamer discharges are formed in the gap between the blocking medium 17, forming abundant active particles (OH, O, H2O2, O3, ONOOH, etc.). At the same time, the atomizing device 6 starts to work, and the high-frequency vibration of the atomizing sheet in the atomizing device 6 is used to atomize the water surface into a very small water mist. The strong electric energy breaks the water into tiny floating particles, forming an atomized beam. The waterproof fan 25 drives the atomization beam to pass through the atomization outlet pipe. The refrigeration device 12 is used to maintain a specific temperature range, including thermal insulation cotton 19, a refrigeration sheet 20, a cooling block 21, a heat sink 22, a cold end small fan 23 and a hot end fan 24, wherein the surface of the cooling block 21 is coated with thermal grease and fits with the cooling surface of the refrigeration sheet 20, the thermal insulation cotton 19 is placed around the refrigeration sheet, and the cold end small fan 23 is located on the surface of the cooling block 21, the heat sink 22 fits with the hot surface of the refrigeration sheet 20 through thermal grease, the hot end fan 24 is located on the surface of the heat sink 22, and the cooling block 21 is embedded in the inner surface of the mist outlet pipe 13; the refrigeration device 12 cools the atomization beam, and the water mist is transported through the multi-layer micro-spacing discharge generating device 14 for one activation. The smaller the water droplet particles are, the larger the contact surface with the plasma gas is, and the higher the solubility is. At this time, it is a mixture of partially activated water mist and plasma gas components, and the active particles are dissolved in the atomization beam to form an initially activated atomization beam.

[0040] Under the action of the waterproof small fan 26, the water mist activated for the first time is then liquefied and compressed in a small range under the action of wind. In the process of small water droplets condensing into larger water droplets, water and plasma gas components are further dissolved, further improving the degree of activation of the water mist. The water mist particles after secondary activation are larger and can cover samples at a longer distance under the action of wind, with better effect. Through the mist outlet pipe 13, the atomized beam is sprayed onto food or the environment, thereby achieving the effect of sterilization and disinfection. The time control device can automatically control the work-stop cycle of the humidifier according to the operator's settings.

[0041] After working for a period of time, if the water tank 1 needs to be cleaned, the operator can select the self-cleaning mode in the control panel 9, replace the self-cleaning mist outlet circular tube 27, connect the cleaning inlet 8, add water to the top water injection port 3 of the water storage tank 1 on the side surface of the box body to the scale line, or connect the water pipe through the external water injection port 4 for automatic water injection. When the main motor 11 is started, it provides power for the entire system. The main motor is used to provide power for the refrigeration device 12 to ensure that it can operate. The refrigeration device 12 starts working, and the temperature sensor measures to ensure that the temperature in the mist outlet pipe 13 reaches 20±1°C. When the temperature reaches the set temperature, the high-voltage and high-frequency power supply is driven to work, and the multi-layer micro-spacing discharge generating device 14 is started. The air in the mist outlet pipe 13 passes through the multi-layer micro-spacing discharge generating device 14 to form rich active particles. At the same time, the atomizing device 6 starts to work, the atomizing sheet vibrates, the fan drives the atomizing beam to pass through the atomizing pipe 13, the refrigeration device 12 cools the atomizing beam, and passes through the multi-layer micro-spacing discharge generating device 14 to generate an activated atomizing beam. After passing through the self-cleaning atomizing circular pipe, the activated mist is transported back to the water tank 1 and diffuses in the water tank 1 to self-clean and disinfect the inner wall of the water tank 1, the air environment, etc. Finally, the residual water after cleaning is discharged through the water outlet 7.

[0042] Red grapes and strawberries generally have a short shelf life, so they were used for cold chain logistics preservation experiments. Fresh red grapes and strawberries without mechanical damage and of uniform size were selected and immediately transported to the laboratory after harvesting. Rotten, cracked, and mechanically damaged fruits were removed, and red grapes and strawberries with intact berries, uniform size, uniform color, and similar maturity were selected as test materials. Fresh red grapes and strawberries were spread flat on the supermarket display cabinet and treated with ordinary water mist humidification as the control group.

[0043] The setting mode is to run the multi-layer micro-spacing discharge atomizing automatic humidifier for 10 minutes every 4 hours. The temperature is set to 20±1℃, the input power is 80W, the pH value of the water mist is 2.2, and the redox potential ORP value is 542mV.

[0044] It can be found that the red grapes or strawberries placed in the multi-layer micro-pitch discharge atomization automatic humidifier remain fresh and free of mold growth, while the red grapes and strawberries in the control group have obvious mold growth, especially nearly 50% of the strawberries in the control group (ordinary water mist humidification treatment) have mold.
