[0024] A type of cold chain delivery box, such as Figures 1-4 As shown, the system includes a delivery box body 1 and a refrigeration tank 2 filled with dry ice. The refrigeration tank 2 is made of stainless steel and has a cover 3. A sealing ring 15 is fixedly connected to the bottom of the cover 3 to effectively improve the sealing effect between the cover 3 and the refrigeration tank 2, preventing the cold air inside the refrigeration tank 2 from leaking out. The cover 3 has a through hole 4. A gas supply pipe 5 for supplying cold air is fixedly connected to the delivery box body 1. One end of the gas supply pipe 5 passes through the delivery box body 1, and the other end is detachably connected to the through hole 4. The cover 3 is equipped with an air pump 6 that pressurizes the inside of the refrigeration tank 2. The air pump 6 is a miniature air pump that can actively control the dry ice vaporization rate and realize the directional delivery of cold air, improving delivery efficiency. When using the cold chain delivery box to deliver vegetables, place the delivery box body 1, then put the vegetables into the delivery box body 1 and close the delivery box body 1, then rotate... The lid 3 opens the refrigeration tank 2, then dry ice is placed inside the refrigeration tank 2 and the lid 3 is closed. Finally, the air supply pipe 5 and the through hole 4 of the lid 3 are connected to each other, and the air pump 6 is started. The air pump 6 supplies air into the refrigeration tank 2. At this time, the air pressure inside the refrigeration tank 2 increases. The dry ice in the refrigeration tank 2 releases cold air, which is affected by the air pressure and moves upward to the through hole 4 of the lid 3 and enters the air supply pipe 5. The cold air can be delivered to the delivery box body 1 through the air supply pipe 5, thereby achieving the effect of cold chain for the vegetables in the delivery box body 1. With the setting of the refrigeration tank 2 and the air supply pipe 5, there is no need to place crushed ice and ice packs in the delivery box body 1 to achieve the effect of refrigeration for the vegetables in the delivery box body 1. This avoids the vegetables at the bottom of the delivery box body 1 from being soaked in water, thereby preventing the vegetables from becoming soft and rotten and improving the freshness of the vegetables.

[0025] Furthermore, an installation tube 7 is fixedly connected to one end of the gas pipe 5 near the cover 3. The installation tube 7 is slidably connected to the through hole 4. A cap 8 is rotatably connected to the outer wall of the installation tube 7. An installation ring 9 is fixedly connected to the side wall of the through hole 4. The cap 8 and the installation ring 9 are threadedly connected. A limit ring 10 is fixedly connected to the outer wall of the installation tube 7. The limit ring 10 and the inner wall of the cap 8 are in contact with each other. The installation tube 7 and the gas pipe 5 are fixedly connected by a corrugated pipe 11. The position and orientation of the installation tube 7 can be changed according to the actual situation, which facilitates the subsequent installation of the installation tube 7 and the cover 3. When installing the gas pipe 5 and the cover 3, the installation tube 7 is inserted into the installation ring 9. Then, the cap 8 is rotated to thread the cap 8 and the outer wall of the installation ring 9 until the two sides of the limit ring 10 are in contact with the installation ring 9 and the cap 8 respectively. At this time, the installation tube 7 is restricted and cannot be separated from the installation ring 9, thus completing the effect of installing the gas pipe 5 and the cover 3.

[0027] A filter screen 14 is fixedly connected to one end of the gas supply pipe 5 inside the delivery box body 1, which can prevent vegetable leaves or other impurities from entering the gas supply pipe 5 and prevent the gas supply pipe 5 from becoming blocked.

[0028] The usage process of this utility model is as follows:

[0029] When using a cold chain delivery box to deliver vegetables, place the delivery box body 1, then put the vegetables inside and close the delivery box body 1. Next, rotate the lid 3 to open the refrigeration tank 2, then put dry ice into the refrigeration tank 2 and close the lid 3. Finally, connect the air supply pipe 5 and the through hole 4 of the lid 3 and start the air pump 6. The air pump 6 supplies air into the refrigeration tank 2, which increases the air pressure. The dry ice in the refrigeration tank 2 releases cold air, which is affected by the air pressure and moves upward to the through hole 4 of the lid 3 and enters the air supply pipe 5. The air supply pipe 5 can deliver cold air into the delivery box body 1, thereby achieving the effect of cold chain for the vegetables in the delivery box body 1. With the setting of the refrigeration tank 2 and the air supply pipe 5, there is no need to put crushed ice and ice packs in the delivery box body 1 to achieve the effect of refrigeration for the vegetables in the delivery box body 1. This avoids the vegetables at the bottom of the delivery box body 1 from being soaked in water, thus preventing the vegetables from becoming soft and rotten and improving the freshness of the vegetables.
