The distance between the bottom of the blocking rod 315 and the top of the inner cavity of the transport box 100 is equal to the distance between the bottom of the piston 304 and the top of the exhaust port 303.

[0026] When the berries in the transport box 100 are almost fumigated, the gas generated in the transport box 100 gradually increases, and the air pressure in the transport box 100 gradually increases. At this time, the piston 304 is pushed to move upward. When the piston 304 moves into the installation cylinder 301 and is within the range that the electromagnet 312 can adsorb, the electromagnet 312 adsorbs the iron sheet 308, drives the iron sheet 308 and the exhaust fan 306 to move upward, so that the plug plate 313 is inserted into the slot 307, and the top plate 309 contacts the control switch 311. The control switch 311 is used to control the motor 310 to start, and the motor 310 drives the exhaust fan 306 to rotate through the plug plate 313, thereby extracting the gas in the transport box 100 and discharging the excess fumigation gas in the transport box 100, so as to facilitate ventilation of the transport box 100.

[0027] The fumigation assembly 400 includes a fumigator 401, a conduit 402, a gas channel 403, a fumigation nozzle 404 and a hose 405.

[0028] When the return spring 209 is in a free state, the spray direction of the gas channel 403 and the fumigation nozzle 404 is toward the center of the support plate 202. A plurality of fumigation nozzles 404 are evenly distributed along the extension direction of the gas channel 403 at the bottom of the gas channel 403.

[0029] The bottom of the card plate 211 is in an arc shape, and the connection between the card slot 210 and the berry tray 203 is in an arc shape. The shape characteristics of the card plate 211 and the card slot 210 make it easy for the card plate 211 to enter the card slot 210 or slide out from the card slot 210.

[0030] Working principle: When using the device, the fumigant is placed in the fumigator 401, the fumigator 401 is connected to an external power source, the fumigator 401 is started, the agent is sprayed out from the fumigation nozzle 404 through the conduit 402 and the gas channel 403, berries are placed in the berry tray 203, and one side of the berry tray 203 is pushed into the transport box 100 from the entrance 201. At this time, the top of the berry tray 203 contacts the card plate 211, pushing the card plate 211 to rotate, the return spring 209 is twisted, and the lower gear 208 is driven to rotate. Due to the meshing connection between the lower gear 208 and the upper gear 206, the connecting shaft 204 and the mounting seat 205 on the upper gear 206 are driven to rotate, thereby driving the gas channel 403 and the fumigation nozzle 404 on the mounting seat 205 to blow mist toward the entrance 201. The berry tray 203 is completely pushed into the transport box 100. At this time, the card plate 211 enters the card slot 210, and the return spring 209 is reset to limit the position of the berry tray 203. As the gas in the transport box 100 increases, the berries are fumigated, and the air pressure in the transport box 100 increases. The air pressure in the transport box 100 pushes the piston 304 to move upward, and the exhaust port 303 is used to connect the transport box 100 with the outside world, so that part of the gas in the transport box 100 is discharged; When the berries in the transport box 100 are almost fumigated, the electromagnet 312 is connected to the external power supply to generate magnetic force, the gas generated in the transport box 100 gradually increases, and the air pressure in the transport box 100 gradually increases. At this time, the piston 304 is pushed to move upward. When the piston 304 moves into the installation cylinder 301 and is within the range that the electromagnet 312 can adsorb, the electromagnet 312 adsorbs the iron sheet 308, drives the iron sheet 308 and the exhaust fan 306 to move upward, so that the plug board 313 is inserted into the slot 307, and the top plate 309 contacts the control switch 311. The control switch 311 is used to control the motor 310 to start, and the control motor 310 is connected to the external power supply. The motor 310 drives the exhaust fan 306 to rotate through the plug board 313, thereby extracting the gas in the transport box 100, discharging the excess fumigation gas in the transport box 100, and ventilating the transport box 100.
