[0024] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0025] Please refer to Figure 1 to Figure 2 , the first embodiment of the utility model:

[0026] A vegetable and fruit fresh-keeping atmosphere-conditioning device, comprising a tray 1 and a fresh-keeping storage mechanism;

[0027] The fresh-keeping storage mechanism 2 is placed on the tray 1, and the fresh-keeping storage mechanism includes a storage box and a storage unit box 23;

[0028] The storage box is a rectangular box body 21 with an opening at the top, and a plurality of gas delivery branches 22 are arranged in a rectangular array at the bottom of the inner wall of the storage box;

[0029] The bottom of the storage unit box 23 is provided with an air inlet 24 corresponding to the air delivery branch pipe 22 .

[0030] In this embodiment, a gas main pipe 25 is provided in the storage box, and the plurality of gas branch pipes 22 are all connected to the gas main pipe 25. The gas branch pipes 22 and the gas main pipe 25 form a gas passage in the storage box, and the gas conditioning gas enters the gas branch pipes 22 through the gas main pipe 25.

[0031] When in use, the fruits and vegetables to be preserved are placed in the storage unit boxes 23 to achieve independent storage of the fruits and vegetables, avoiding the problem of collision between adjacent fruits and vegetables during transportation. The storage unit boxes 23 are then placed one by one in the rectangular box 21 and connected to the corresponding gas branch pipes 22. The gas-controlled gas enters the corresponding storage unit boxes 23 through each gas branch pipe 22, thereby achieving gas-controlled preservation of the fruits and vegetables in the storage unit boxes 23.
