[0002] The development of cold chain logistics and the widespread use of household refrigerators have enabled the formation of a complete closed loop of cold chain logistics around the world that can reach every household.

[0035] Working principle: connect the liquid inlet tee pipe 403 to the external coolant pipe, connect the extension pipe 603 to the external liquid discharge pipe, and connect the smoke exhaust duct 313 to the external smoke exhaust channel; When in use, close the tank solenoid valve 405, open the tank solenoid valve 404 and the drain solenoid valve 407, and the coolant enters the interior of the cooling water tank 401 from the liquid inlet tee 403. After the coolant fills the cooling water tank 401, it is discharged from the drain tee 406. Then close the tank solenoid valve 404, open the tank solenoid valve 405, and the coolant enters the interior of the gas washing tank 306 from the liquid inlet tee 403 until the liquid level is higher than the overflow tube 606, and then the overflow tube 606 pushes the membrane frame 607 away to discharge, so that the liquid level is maintained. At this time, the liquid submerges the bottom of the air sealing cover 304 and the isolation cover 307, leaving two air cavities between the isolation cover 307 and the guide bucket 302 and between the air sealing cover 304 and the guide bucket 302 respectively; Then, the cabinet door 104 is opened to place the cold chain logistics on the surface of the conductive plate 205, and then the cabinet door 104 is closed, and the flap 506 is opened, and the moxa cake is ignited and placed in the combustion tank 512, and then the flap 506 is closed, and the magnet block 509 is attracted with the limit iron bar 507, and then the smoke exhaust fan 314 and the spoiler motor 702 are started, and the switch of the high-voltage and low-current DC power supply 201 is turned on, and the smoke exhaust fan 314 continuously pumps the air inside the device outward, so that a slight negative pressure is formed inside the device, and the external air passes through the air filter sponge block 312 and the support net 311 and enters the air washing tank 306 from the smoke inlet elbow 310, and then the air is cleaned by the liquid. After washing, it floats to the inside of the isolation cover 307, then enters the combustion box 501 from the air inlet 502, then reaches the bottom of the air inlet 502 from the air guide bend 514, and then the air enters the combustion groove 512 from the ash leakage hole 513 to continuously replenish the oxygen needed for the combustion of the mugwort cakes, and then the air carries the mugwort smoke into the smoke conveying duct 503, and then enters the smoke exhaust hood 504, and then passes through the flame retardant mesh plate 505 into the inside of the insulating and heat-insulating inner shell 102. At this time, the spoiler motor 702 drives the spoiler rod 703 to rotate, so that the mugwort smoke is evenly dispersed above the negative electrode ionization network 203. After the switch of the high-voltage and low-current DC power supply 201 is turned on, the negative electrode The ionization network 203 carries a negative voltage, and the conductive plate 205 carries a positive voltage. The conductive plate 205 conducts the positive voltage to the surface of the cold chain logistics, making the cold chain logistics positively charged. At the same time, the moxa smoke falls due to the effect of the slight negative pressure. When falling, it passes through the negative electrode ionization network 203, making the moxa smoke ionized and negatively charged, and then enters the insulated heat conduction pipe 409 to be cooled and continue to fall. Due to the mutual attraction of positive and negative charges, the diffusion effect of moxa smoke and the diversion effect of slight negative pressure, most of the negatively charged moxa smoke particles continue to adhere to the surface of the cold chain materials and the conductive plate 205 to form a protective film for disinfection, and then a small amount of moxa smoke is mixed with the air. Pass through the conductive plate 205, then pass through the negative electrode ionization network 203 to enter the guide bucket 302, then enter the air sealing cover 304 from the guide bucket 302, and then enter the liquid for cleaning from the exhaust bend 305. The cleaned gas enters the air cavity below the guide bucket 302, and then enters the exhaust duct 313 from the exhaust port 308, and then is discharged from the exhaust duct 313. After a period of time, the moxa cake is burned, the high-voltage and low-current DC power supply 201 is turned off, and the high-speed mode of the exhaust fan 314 is started to speed up the discharge of the remaining moxa smoke, and then the cabinet door 104 is opened to take out the cold chain logistics, thereby achieving the disinfection of the surface packaging of the cold chain logistics; Then open the box solenoid valve 404, and the coolant inside the cooling water tank 401 enters the washing tank 306 from the liquid inlet three-way pipe 403, and then the electromagnet 613 is energized. After the electromagnet 613 is energized, it attracts the nickel block 616 to rise, and the lifting piston 619 is driven to rise until the lifting piston 619 rises to above the drain port 604. At this time, all the coolant inside the washing tank 306 enters the drain cylinder 602 from the drain port 604, and then is discharged from the epitaxial tube 603.
