Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0026] See also Figures 1 to 5In an embodiment of the present invention, a fruit transportation and preservation system comprises a box body 1, a box cover 4 is installed at the top opening of the box body 1, the box body 1 and the box cover 4 are both made of heat-insulating materials, specifically polypropylene plastic foam material, the box cover 4 is detachably connected to the box body 1 by a buckle, a device seat 11 is detachably installed on the box cover 4, a fan 19 is fixedly connected to the bottom of the device seat 11 through a suspension rod 18, a plurality of net bags 29 for storing dry ice are installed at the bottom of the box cover 4, a device compartment 20 is opened at the top of the device seat 11, a panel 24 is detachably connected to the corresponding part of the top of the device seat 11 and the device compartment 20 through screws, a display 25, a button 26 and a charging interface 27 are installed on the panel 24, a battery 21 and a controller 22 are installed in the device compartment 20, a temperature sensor 23 is installed at the bottom of the device seat 11, and a pressure relief valve 9 is installed on the box cover 4.

[0027] By adopting the above scheme, when in use, after the fruits to be transported are placed in the box body 1, dry ice is placed in the net bag 29, and the box cover 4 is installed on the box body 1, so that the dry ice can be used to keep the fruits in the box body 1 fresh at low temperature, and the carbon dioxide concentration in the box body 1 will increase during the melting and sublimation of the dry ice, so as to inhibit the aerobic respiration of the fruits, thereby further improving the preservation effect of the fruits. In addition, the dry ice in the net bag 29 can avoid direct contact with the fruits, thereby avoiding frostbite of the fruits. By starting the fan 19, the distribution of cold air in the box body 1 can be made more uniform. By setting the pressure relief valve 9, when the air pressure in the box body 1 increases due to the melting and sublimation of the dry ice, the pressure relief valve 9 can discharge the excess gas from the box body 1. By setting the temperature sensor 23 and the display screen 25, the temperature in the box body 1 can be monitored and displayed, so as to facilitate judging whether the dry ice is completely melted according to the temperature in the box body 1, so as to replenish the dry ice in time, and the use effect is good.

[0028] Specific combination Figure 1 In one embodiment of the present invention, the outer contour size of the bottom end of the box body 1 is adapted to the top opening size of the box body 1. Therefore, when no fruit is transported, the bottom end of the upper box body 1 can be inserted into the lower box body 1 to reduce the space occupied by empty box transportation. A support platform 2 is integrally formed in the box body 1, and a bracket 30 is provided on the support platform 2. Through the setting of the bracket 30, the interior of the box body 1 can be divided into an upper and lower layer, so that when transporting fragile fruits (such as strawberries, peaches, etc.), the fruits can be stored in layers to avoid the fruits located at the bottom of the box body 1 from being crushed.

[0029] Specific combination Figure 1 and Figure 5In one embodiment of the present invention, the bracket 30 includes a plurality of first connecting rods 32 and second connecting rods 35, the two ends of the first connecting rod 32 are respectively fixedly connected to the first cross bar 31 and the second cross bar 33, the two ends of the second connecting rod 35 are respectively fixedly connected to the plurality of third cross bars 34 and the fourth cross bar 36, and the second connecting rod 35 is slidably inserted into the second cross bar 33, and the first connecting rod 32 is slidably inserted into the third cross bar 34.

[0030] By adopting the bracket 30 composed of the above components, the length of the bracket can be telescopically adjusted, so that the storage space occupied by the bracket 30 can be reduced when not in use.

[0031] Specific combination Figure 1 In one embodiment of the present invention, second positioning grooves 37 are provided at the surface of the support platform 2 corresponding to the first cross bar 31 and the fourth cross bar 36. Through the setting of the second positioning grooves 37, the first cross bar 31 and the fourth cross bar 36 of the bracket 30 can be positioned on the support platform 2 to prevent the bracket 30 from telescoping during transportation.

[0032] Specific combination Figure 1-4 In one embodiment of the present invention, the box cover 4 includes a main cover plate 5, both ends of the main cover plate 5 are hinged with side cover plates 7 through hinges 6, the net bag 29 is fixedly installed on the bottom of the corresponding side cover plate 7, and the main cover plate 5 is penetrated with a stepped mounting hole 10 adapted to the equipment seat 11, and the pressure relief valve 9 is installed on the main cover plate 5.

[0033] By providing the box cover 4 composed of the main cover plate 5 and the two side cover plates 7, the box cover 4 can be folded, so that the box cover 4 can be stored in the box body 1 when not in use.

[0034] Specific combination Figure 1 and Figure 4 In one embodiment of the present invention, a plurality of pads 3 are fixedly provided at the bottom of the box body 1, and first positioning grooves 8 are provided at the tops of the main cover plate 5 and the side cover plate 7 corresponding to the pads 3, and the height dimension of the pads 3 is greater than the depth dimension of the first positioning grooves 8.

[0035] Through the cooperation of the pad strip 3 and the first positioning groove 8, when transporting fruits, the box body 1 covered with the box cover 4 can be stacked vertically, and the upper box body 1 can be positioned on the box cover 4 conveniently. In addition, since the height of the pad strip 3 is greater than the depth of the first positioning groove 8, a certain gap will be left between the top surface of the box cover 4 and the bottom surface of the box body 1, thereby avoiding interference with the exhaust of the pressure relief valve 9.

[0036] Specific combination Figure 1-3In one embodiment of the present invention, two locking holes 12 are symmetrically provided in the stepped mounting hole 10, and the outer walls on both sides of the equipment seat 11 are slidably connected to the corresponding parts of the locking holes 12 through blind holes 13 with locking rods 14, and one end of the locking rod 14 located in the blind hole 13 is embedded with a spring 15, and the top of the equipment seat 11 and the corresponding parts of the blind hole 13 are provided with opening grooves 16, and the bottom ends of the opening grooves 16 are communicated with the corresponding blind holes 13, and a lever 17 is slidably provided in the opening grooves 16, and the bottom ends of the lever 17 are fixedly connected to the corresponding locking rods 14.

[0037] By pulling the lock rod 14 to move through the lever 17, the end of the lock rod 14 can be inserted into or disengaged from the lock hole 12 to achieve locking or unlocking between the device seat 11 and the main cover 5, thereby facilitating direct replacement of a device seat 11 when the battery 21 is low on power.

[0038] Specific combination Figure 1 In one embodiment of the present invention, the side cover plate 7 is fixedly provided with an inserting strip 28 on the outer wall facing the main cover plate 5, and a slot is provided at the outer wall of the main cover plate 5 corresponding to the inserting strip 28, and the inserting strip 28 is adapted to the slot. The cooperation between the inserting strip 28 and the slot can improve the sealing performance when the main cover plate 5 and the side cover plate 7 are combined.
