[0033] The technical solution of the utility model is further described below with specific embodiments, but the protection scope of the utility model is not limited to the following embodiments.

The refrigeration mechanism generates cold air and sends it into the insulation box through the central channel hole of the workbench and the central ventilation slot at the bottom of the EPS insulation box. The cold air moves upward to the box cover and then diffuses downward in all directions. After covering each test kit on the rotating disk assembly and taking away the heat, it returns to the refrigeration mechanism through the side reflux slot and the central channel hole. The cooling oil is sent upward into the insulation box again to form a cold air circulation.

[0035] Implementation method 2: Figures 7 to 10As shown, the refrigeration mechanism 3 of the reagent disk module includes a semiconductor refrigeration box 31 and an axial flow fan 32. The semiconductor refrigeration box 31 is provided with an air supply hole 311 located directly below the central ventilation slot 211 and a return hole 312 located directly below the side return groove 212. The axial flow fan 32 is installed on the central ventilation slot 211. The axial flow fan draws the cold air generated by the semiconductor refrigeration box upward through the air supply hole into the insulation box and pushes it to the box cover. The cold air diffuses downward to the surroundings and flows back to the semiconductor refrigeration box through the side return groove and the return hole. The refrigeration mechanism 3 also includes a cold water tank 33, a water pump 34, and an air-cooled radiator 35. The cold water tank 33 is connected to the water inlet of the semiconductor refrigeration box 31 through a water hose through the water pump 34, and the drain outlet of the semiconductor refrigeration box 31 is connected back to the cold water tank 33 through a water hose through the air-cooled radiator 35. A water-exchange water tank is provided in each water-cooled semiconductor refrigeration box for removing heat from the hot surface of the semiconductor refrigeration piece. Its water inlet is the water inlet of the water-exchange water tank, and its drain outlet is the drain outlet of the water-exchange water tank. The cold water tank injects cold water into the water-exchange water tank under the action of the water pump. The water tank removes heat from the hot surface of the semiconductor refrigeration piece in a contact manner and conducts it to the cold water. After the cold water is discharged, it is dissipated by the air-cooled radiator and flows back to the cold water tank again to form a cycle. The remaining structures and components are as described in Implementation 1 and will not be described again.

A plurality of track wheel frames are installed circumferentially around the periphery of the central ventilation slot, and then the inner edge of the rotating disk is clamped in the grooves of these I-shaped guide wheels to realize the rotation connection of the rotating disk in the EPS incubator. The remaining structures and components are as described in Implementation 1 and will not be described again.

[0037] Implementation 4: Fig.13 As shown, the driving assembly 5 of the reagent disk module includes a driving motor 51 installed in the fixing groove 213 and a driving gear 52 arranged on the output shaft of the driving motor 51. A gear ring 411 is fixed to the lower surface of the rotating disk 41, and the gear ring 411 is meshed with the driving gear 52. Through the transmission of the driving gear-gear ring, the driving motor drives the rotating disk to rotate, so that the reagent kit on the rotating disk is evenly cooled. The remaining structures and components are as described in Implementation 1 and will not be described again.

[0038] Implementation 5: A temperature sensor 321 is installed on one side of the axial flow fan 32 of the reagent tray module. The ambient temperature in the heat preservation mechanism can be collected in real time, which can be used for real-time monitoring of the reagent environment, and can be used in conjunction with the single-chip microcomputer to control the speed of the axial flow fan to achieve constant temperature automatic adjustment based on temperature signal feedback. The remaining structures and components are as described in Implementation 1 and will not be described again.
