[0045] like Figures 1 to 6 As shown, this embodiment provides a medicine cold chain box, including a box body 11, a conveyor 12, a storage seat 13, a door body, and a refrigerator. The door body and the refrigerator are not shown in the figure. The refrigerator is a refrigeration device such as a heat pump unit.

[0046] The housing 11 has a refrigeration tank 111 and a take-in and take-out port 112. The refrigeration tank 111 is connected to the outside of the housing 11 through the take-in and take-out port 112. Medicines that need to be refrigerated are stored in the refrigeration tank 111 from the take-in and take-out port 112, and medicines that need to be taken out from the refrigeration tank 111 can also be taken out from the take-in and take-out port 112. The refrigerator has a refrigeration channel. The refrigeration channel is connected to the refrigeration tank 111, and the cold air produced by the refrigerator enters the refrigeration tank 111, so that a low-temperature environment is formed in the refrigeration tank 111. The refrigeration tank 111 is used to accommodate medicines to achieve refrigeration of the medicines.

[0047] The conveyor 12 has a plurality of conveying parts 124 that move along a circular track. The plurality of conveying parts 124 cyclically move along the circular track. The circular track may be a circular ring, an elliptical ring, a waist-shaped ring, etc. The plurality of conveying parts 124 are arranged at intervals along the circular track. The pick-up and release ports 112 are located on the moving paths of the plurality of conveying parts 124. When the plurality of conveying parts 124 move along the circular track, they may pass through the pick-up and release ports 112 and stay at the pick-up and release ports 112.

[0048] The storage seat 13 is used to place medicines. The storage seat 13 is rotatably mounted on the conveying portion 124. The storage seat 13 has a storage portion 135 located in the cold storage tank 111, and the medicine is placed on the storage portion 135, and the storage portion 135 is kept moving in the cold storage tank 111. There are multiple storage seats 13 and they correspond to multiple conveying portions 124 one by one. The circular track can be completely located in the box, or part of it can be located in the box and part of it can be located outside the box. When a part of the circular track is located outside the box, the conveying portion 124 will move through the outside of the box, so the storage portion 135 is installed on the conveying portion 124 through a connecting structure, so that the storage portion 135 is kept moving in the cold storage tank 111 and close to or away from the access port 112. The storage portion 135 does not need to be moved outside the box, avoiding the problem of the existing drawer-type medicine-taking method that the medicine moves between the box and the outside, thereby avoiding the frequent switching of the medicine in different temperature environments, improving the refrigeration effect of the medicine, and ensuring the efficacy of the medicine. The storage seat 13 moves along the circular track driven by the conveying part 124, and the storage seat 13 can rotate relative to the conveying part 124 under the action of gravity to prevent the medicine placed on the storage seat 13 and the storage part 135 from tilting or turning over. The conveying part 124 drives the storage seat 13 to move when moving along the circular track. When the storage seat 13 moves to the access port 112, the medicine that needs to be taken and placed can be placed on the storage seat 13 conveniently and quickly, and the medicine on the storage seat 13 can be taken out conveniently and quickly, and other medicines that do not need to be taken out are away from the access port 112. Reduce the influence of external temperature on other medicines in the cold storage tank 111. The door body is movably installed on the box body 11 to cover or stay away from the access port 112. The door body can be rotatably or slidably installed on the box body 11. When the medicine needs to be taken and placed, the door body is opened so that the door body is away from the access port 112. After the access is completed, the door body is closed so that the door body covers the access port 112 to achieve heat preservation.

[0049] When in use, the conveyor 12 is first started, and the conveyor 12 first drives the required storage seat 13 to move to the access port 112, and then the door body is opened, and then the medicine can be quickly placed on the storage seat 13 located at the access port 112 or taken out from the storage seat 13 located at the access port 112, and the door body is quickly closed after the storage of the medicine is completed to complete the operation. In this way, the pharmaceutical cold chain box of this embodiment can facilitate the storage and access of medicines, improve the refrigeration effect of medicines, and ensure the efficacy of medicines.
