[0036] The reheating plate 53 has its back side slidably connected to the slide rail frame 51 near the outer end via a sliding plate. The top of the reheating plate 53 is fixedly connected to a lower contact tooth 531, which is staggered with the upper contact tooth 521. The reheating plate 53 is located on the front of the cooling plate 52. The sliding plate on the back of the reheating plate 53 is slidably connected to the slide rail frame 51 via a spring. A protrusion is provided on the inner side of the sliding plate of the reheating plate 53, which is located on the back of the protrusion of the cooling plate 52.

[0037] The switching kit 54 is provided at the bottom of the inner wall of the outer housing 1. The switching kit 54 includes a support frame 541 fixedly connected to the bottom of the inner wall of the outer housing 1. An actuating gear 542 is rotatably connected to the top of the support frame 541. A shaft block 543 is rotatably connected to the outer side of the actuating gear 542. An electric push rod 544 is rotatably connected to the bottom of the shaft block 543. The electric push rod 544 is fixedly connected to the inner wall of the outer housing 1.

[0038] A switching push block 55 is provided in the middle of the support frame 541. The switching push block 55 includes a main shaft 551 rotatably connected to the middle of the support frame 541. The outer surface of the main shaft 551 meshes with the outer surface of the actuating gear 542. A rear shift block 552 is fixedly connected to the inner side of the main shaft 551, and a front shift block 553 is fixedly connected to the outer side of the main shaft 551. The rear shift block 552 and the front shift block 553 form a 90° angle. The rear shift block 552 is located on the back of the protrusion of the cooling plate 52, and the front shift block 553 is located on the front of the protrusion of the reheating plate 53.

[0039] The inner box 3 is equipped with a ventilation frame 6, which includes a support column 61 fixedly connected to the inner box 3. The front and back of the support column 61 are fixedly connected to the mounting plate 62. The top of the mounting plate 62 has a through hole. The top of the support column 61 has a through hole, and the front of the support column 61 has a through hole. The left and right sides of the outer box 1 are connected to external fans 7. One external fan 7 is used for air intake, and the other external fan 7 is used for air exhaust. The box cover 2 is connected to a circulation pipe 8. The bottom of the circulation pipe 8 is connected to three evenly distributed through holes. The through holes at both ends of the circulation pipe 8 are connected to internal fans 81. The top of the box cover 2 is fixedly connected to a display screen 9, which is used to display the heat preservation and reheating status of the box and the temperature inside the inner box 3. The box cover 2 is fixedly connected to a control circuit board.

[0040] When in use, take out the ventilation rack 6, place the blood products to be transported between the adjacent placement plates 62, then put the ventilation rack 6 back into the inner box 3, close the box cover 2, and fasten the buckle 11.

[0041] During the heat preservation process, the cooling end of the semiconductor cooler 42 contacts the cooling plate 52 through the slide rail 51, thereby absorbing the heat inside the inner box 3 through the low-temperature cooling plate 52, thereby reducing the temperature inside the inner box 3, and thus maintaining a relatively low temperature inside the inner box 3, improving the preservation effect of blood products.

[0042] When rewarming is required, the electric push rod 544 pushes the actuating gear 542 to rotate. The actuating gear 542 drives the switching push block 55 to rotate. After the switching push block 55 rotates, on the one hand, the rear lever 552 disengages from the cooling plate 52, allowing the cooling plate 52 to move outward and detach from the inner box 3. At the same time, the front lever 553 contacts the protrusion of the rewarming plate 53, allowing the rewarming plate 53 to come close to the inner box 3. Since the rewarming plate 53 is in contact with the heating end of the semiconductor cooler 42, the rewarming plate 53 is in a high temperature state at this time. Therefore, the rewarming plate 53 transfers heat to the inside of the inner box 3, promoting the rewarming of the inside of the inner box 3.

[0043] During the heat preservation and reheating process, the temperature sensor inside the inner chamber 3 monitors the temperature change inside the inner chamber 3 in real time and transmits the temperature data inside the inner chamber 3 back to the control board in real time. The control board transmits the heat preservation and reheating status and the current temperature information inside the inner chamber 3 to the display screen 9 for the user to view.

[0044] Since the heat preservation and reheating of the state conditioning component 5 starts from the front and back of the inner box 3, in order to make the cooling and heating more uniform and improve the cooling and heating efficiency, the inner fan 81 draws the air near the front and rear ends of the inner box 3 into the circulation pipe 8, and then discharges the air from the through hole in the middle of the bottom of the circulation pipe 8, thereby promoting the temperature of the middle part of the inner box 3 to become uniform as soon as possible.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
