A circulating fan 6500 is arranged in the cavity 6110. The circulating fan 6500 is used to circulate the cold air in the cavity 6110 so that the cold air is evenly distributed in the cavity 6110.

[0055] In some embodiments, the cooling sheet is a semiconductor cooling sheet disposed on the top of the cooling head 6220. The semiconductor cooling sheet has the advantages of no moving parts, small size, easy installation, no refrigerant pollution, high reliability, etc., and has a better cooling effect.

[0056] In some embodiments, the radiator 6230 is connected to the cooling fan 6240, and the radiator 6230 is connected to the bottom of the cold storage bin 6100.

Thus, by providing the heat-insulating layer 6130, the heat exchange between the cold storage bin 6100 and the outside air is isolated, thereby improving the cold storage effect.

[0060] In some embodiments, a turntable 6400 is disposed in the cavity 6110, and the turntable 6400 is located below the circulation fan 6500. A plurality of placement racks 6410 for placing reagent bottles 6700 are sequentially arranged on the turntable 6400 along its circumferential direction. The top of the cavity 6110 is covered by a cover plate 6140, and a first through hole 6141 is provided on the cover plate 6140 at the reagent absorption station. The turntable 6400 is connected to the driving member 6300, and the driving member 6300 drives the turntable 6400 to rotate.

[0061] It should be noted that the number and arrangement of the racks 6410 depend on the size of the cavity 6110 , the size of the turntable 6400 and other specific conditions. The number of reagent aspiration stations on the cover 6140 may be one or more than two, for example, two reagent aspiration stations.

[0062] When it is necessary to take the reagents in the cold storage bin 6100, the driving member 6300 drives the turntable 6400 to rotate, and the placement rack 6410 rotates together with the turntable 6400, so that the reagent bottles 6700 on the placement rack 6410 correspond to the first through holes 6141, and the reagent bottles 6700 can also be mixed to prevent the magnetic beads in the magnetic bead liquid bottle 6710 from sinking to the bottom.

Thus, the cover door 6142 is opened and closed by the handle 6143, so that the reagent bottle 6700 in the cavity 6110 can be replaced, and maintenance and other operations are more convenient.

[0066] In some embodiments, a plurality of reagent bottles 6700 are arranged in sequence along the radial direction of the turntable 6400 on each placement rack 6410, wherein the reagent bottle 6700 close to the outer side of the turntable 6400 is a magnetic bead liquid bottle 6710, and a planetary gear 6450 is provided on the turntable 6400 to cooperate with each magnetic bead liquid bottle 6710, and the magnetic bead liquid bottle 6710 is connected to the planetary gear 6450 and rotates together, and each planetary gear 6450 is respectively arranged on the second rotating shaft 6440, and each second rotating shaft 6440 is arranged on the turntable 6400 in the vertical direction, and an inner gear ring 6160 cooperating with each planetary gear 6450 is provided at the bottom of the cavity 6110, and there are multiple first through holes 6141 at the reagent absorption station and can correspond one-to-one with the reagent bottles 6700 on the placement rack 6410.

[0068] When the turntable 6400 rotates, the inner gear ring 6160 cooperates with each planetary gear 6450 to synchronously drive each planetary gear 6450 to rotate, and each magnetic bead liquid bottle 6710 rotates together with its corresponding planetary gear 6450, so that the magnetic bead liquid in the magnetic bead liquid bottle 6710 can be better mixed, preventing the magnetic beads from sinking to the bottom, etc., which is more stable and reliable.

[0069] In some embodiments, each planetary wheel 6450 is provided with a positioning pin 6430 that matches the magnetic bead liquid bottle 6710.
