[0002] Berries are small, fleshy fruits that develop from the ovary or other associated floral organs. They are typically round, thin-skinned, thick-fleshed, and juicy. Most berries are consumed fresh or processed. Blueberries, strawberries, grapes, mulberries, cranberries, raspberries, and currants are among the most common. Today, berries comprise the largest portion of the human diet, and their properties have become a focus of research. This is attributed to their rich content of phenolic compounds, organic acids, vitamins, anthocyanins, and other special active ingredients, as well as various nutritional and health factors.

The outer side of the rotating shaft 207 is connected to the rear side of the inner cavity of the transport box 100 by a return spring 209. The front and rear sides of the connecting shaft 204 are fixedly connected with a mounting seat 205 and an upper gear 206 respectively. The outer side of the rotating shaft 207 is fixedly connected with a lower gear 208. The outer teeth of the lower gear 208 are engaged with the outer teeth of the upper gear 206. A card slot 210 is opened on the rear side of the top of the berry tray 203, and a card plate 211 located in the inner cavity of the card slot 210 is fixedly installed on the rear side of the lower gear 208.

[0034] The transport box 100 is provided with a berry entry assembly 200. When the berry tray 203 enters the transport box 100, it squeezes the card plate 211, driving the lower gear 208 to rotate. Due to the engagement between the lower gear 208 and the upper gear 206, the upper gear 206 is driven to rotate, driving the gas channel 403 and the fumigation nozzle 404 on the mounting seat 205 to rotate toward the entrance 201, so that the fresh-keeping mist sprayed by the fumigation nozzle 404 is sprayed at the entrance of the berries into the transport box 100, which can reduce the oxygen outside the device from entering the transport box 100, reduce the oxygen for respiration between the transport box 100 and the berries, and improve the fresh-keeping life of the berries.

[0035] The ventilation component 300 includes a mounting cylinder 301, a mounting plate 302, an exhaust port 303, a piston 304, and a guide rod 305. The top of the transport box 100 is fixedly sleeved with the mounting cylinder 301, the upper part of the inner cavity of the mounting cylinder 301 is fixedly sleeved with the mounting plate 302, the lower part of the inner cavity of the mounting cylinder 301 is movably sleeved with the piston 304, the top of the piston 304 is fixedly connected to the guide rod 305, the top of the guide rod 305 is movably sleeved on the mounting plate 302, and the outer side of the mounting cylinder 301 is provided with a mounting plate 302 located above the piston 304. A mounting cylinder 301, a mounting plate 302, an exhaust port 303, a piston 304 and a guide rod 305 are provided on the upper part of the transport box 100. When the transport box 100 is fumigated, the air pressure in the transport box 100 will increase, and the air pressure in the transport box 100 will push the piston 304 to move upward. The exhaust port 303 is used to connect the transport box 100 with the outside world, thereby discharging part of the gas in the transport box 100, thereby avoiding damage to the berries or the entire device due to excessive pressure.

[0036] The ventilation assembly 300 also includes an exhaust fan 306, a slot 307, an iron sheet 308, a top plate 309, a motor 310, a control switch 311, an electromagnet 312, a plug plate 313, a connecting rod 314, a blocking rod 315, an air inlet 316 and an air exchange port 317. The middle part of the piston 304 is rotatably connected to the exhaust fan 306. The top of the exhaust fan 306 is provided with a slot 307. The top of the piston 304 is fixedly mounted with an iron sheet 308 and a top plate 309. The bottom of the mounting plate 302 is respectively An electromagnet 312 and a control switch 311 are provided. A motor 310 is installed in the center of the mounting plate 302. The output end of the motor 310 is connected to the plug plate 313 through the bottom of the mounting plate 302. A ventilation port 317 located above the exhaust port 303 is provided on the outside of the mounting cylinder 301. An air inlet 316 is provided on one side of the top of the transport box 100. A blocking rod 315 is movably connected to the inner cavity of the air inlet 316. The top of the blocking rod 315 is connected to the top of the guide rod 305 by a connecting rod 314.

[0037] There are multiple ventilation ports 317, evenly distributed along the circumference of the mounting tube 301. The control switch 311 is located directly above the top plate 309, and the guide rod 305 is positioned outside the piston 304, away from the center. 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.

[0038] As 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, driving 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 motor 310 drives the exhaust fan 306 to rotate through the plug board 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.

[0039] The fumigation assembly 400 includes a fumigator 401, a conduit 402, a gas channel 403, a fumigation nozzle 404 and a hose 405. The fumigator 401 is provided at the bottom of the inner cavity of the transport box 100, the output port of the fumigator 401 is connected to the conduit 402, the output port of the conduit 402 is connected to the hose 405, the gas channel 403 is fixedly installed at the bottom of the mounting base 205, the bottom of the gas channel 403 is connected to the fumigation nozzle 404, and one end of the hose 405 is connected to the gas channel 403.

[0040] When the return spring 209 is in a free state, the gas channel 403 and the fumigation nozzle 404 spray 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.

[0041] 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. Through the shape characteristics of the card plate 211 and the card slot 210, it is convenient for the card plate 211 to enter the card slot 210 or slide out from the card slot 210.

[0042] Working principle: When using this device, the fumigant is placed into the fumigator 401, the fumigator 401 is connected to an external power source, the fumigator 401 is started, and 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 inlet 201. At this time, the top of the berry tray 203 contacts the card plate 211, pushing the card plate 211 to rotate, and the return spring 209 is twisted, driving the lower gear 208 to rotate. Due to the meshing connection between the lower gear 208 and the upper gear 206, the connecting shaft 204 and the mounting base 205 on the upper gear 206 are driven to rotate, thereby driving the gas channel 403 and the fumigation nozzle 404 on the mounting base 205 to blow mist toward the inlet 201.

[0043] The berry tray 203 is fully 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. The air pressure in the transport box 100 increases, and the air pressure in the transport box 100 pushes the piston 304 to move upward. The exhaust port 303 is used to connect the transport box 100 to the outside, thereby partially exhausting the gas in the transport box 100.

[0044] 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 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, driving 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.
