DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present utility model.

[0027] like Figure 1 As shown, a reagent storage device includes a refrigeration bin 1 for storing reagent bottles 2; a refrigeration mechanism 3 for cooling the refrigeration bin 1; a refrigeration bin cover 4 arranged on the top of the refrigeration bin 1; and a circulation mechanism arranged in the refrigeration bin cover 4 for circulating cold air in the refrigeration bin 1.

[0028] The circulation mechanism can absorb the cold air in the refrigeration bin, and then discharge the cold air into the refrigeration bin through the refrigeration bin cover, so that the cold air between the refrigeration bin and the refrigeration bin cover can be continuously circulated, preventing external heat from being introduced into the refrigeration bin, improving the low-temperature preservation effect in the refrigeration bin, and effectively increasing the opening validity period of reagents with high requirements for shelf life.

[0029] like Figure 2 As shown, the refrigeration compartment cover 4 includes an upper cover 5 and a lower cover 6. The upper cover 5 is connected to the external space, and the lower cover 6 is connected to the refrigeration compartment 1. A circulation space is formed between the upper cover 5 and the lower cover 6, and a circulation mechanism is arranged in the circulation space.

[0030] Specifically, the upper cover 5 and the lower cover 6 are provided with sampling holes 7 which are in communication with each other, so that the sampling needle can pass through the sampling hole 7 to absorb the reagent stored in the refrigeration chamber 1 .

[0031] The circulation mechanism of the present invention is a circulation fan 8. In other embodiments, other mechanisms may be used to circulate the cold air in the refrigeration compartment.

[0032] The utility model absorbs cold air in the refrigeration bin by a circulating fan, and then discharges the cold air into the refrigeration bin through a sampling hole arranged on the lower cover, so that the cold air in the refrigeration bin circulates continuously, reduces the efficiency of heat introduced into the refrigeration bin from the top of the refrigeration bin, and makes the cold air inside the refrigeration bin fully contact with the reagent bottle, so that the temperature in the reagent bottle is kept constant and at a low temperature.

[0033] like Figure 3 As shown, the refrigeration mechanism 3 includes a cooling fan 9, a heat conducting plate 10, a cooling fin 11 and a heat sink 12; the cooling fin 11 is sealed between the heat sink 12 and the heat conducting plate 10; the cooling fan 9 is arranged on the side of the heat sink 12 away from the cooling fin 11; and the side of the heat conducting plate 10 away from the cooling fin 11 is installed at the bottom of the outer side of the refrigeration chamber 1.

[0034] Specifically, the refrigeration fin 11 is sealed between the heat sink 12 and the heat conducting plate 10 through a waterproof rubber ring 13 ; the heat sink 12 and the heat conducting plate 10 are fixed to the bottom of the refrigeration chamber 1 through a spring 14 .

[0035] During operation, the top of the refrigeration plate 11 is a cold surface and the bottom is a hot surface. The heat at the bottom of the refrigeration bin 1 is conducted to the refrigeration plate 11 through the heat conduction plate 10, and the heat of the air in the refrigeration bin 1 is continuously conducted to the bottom of the refrigeration bin 1, so that the air in the refrigeration bin 1 forms cold air.

[0036] The utility model fixes the refrigeration mechanism by means of a spring, so that the pressure around the refrigeration plate is uniform, the heat conduction effect of the refrigeration plate is increased, and the service life is prolonged.

[0037] Furthermore, the cooling plate in the present invention adopts a Peltier structure, and other cooling structures may also be adopted in other embodiments.

[0038] like Figure 4 As shown, it also includes a bracket 15 for placing the reagent bottle 2. An inlet and outlet are provided at one end of the refrigeration bin 1, and the bracket 15 can be inserted into or pulled out of the refrigeration bin 1 through the inlet and outlet; a guide bar 16 is provided at the bottom of the inner side of the refrigeration bin 1, and the bracket 15 moves along the guide bar 16 when being inserted into or pulled out of the refrigeration bin 1.

[0039] Furthermore, a collecting tank 17 is provided at one end of the inlet and outlet of the refrigeration bin 1. When the bracket 15 is pulled out of the refrigeration bin 1, the condensed water at the bottom of the bracket 15 is collected by the collecting tank 17, and the condensed water in the collecting tank 17 is discharged at a regular time by setting a drainage pump to ensure that the condensed water will not overflow after it is generated.

[0040] Since the refrigeration warehouse is a low-temperature environment, the refrigeration warehouse uses sealing rubber rings, insulation surfaces, glue and other measures, which will cause condensation water to be generated when the internal humidity is too high. The collection tank can effectively solve the accumulation of condensation water in the refrigeration warehouse.

[0041] The utility model also discloses a coagulation analyzer, comprising the reagent storage device mentioned above.

[0042] The utility model adopts a semiconductor refrigeration sheet to cool the refrigeration bin, so that the validity period of the reagent stored in the refrigeration bin is prolonged, and the circulation mechanism on the top is used to increase the refrigeration effect, so as to achieve the best refrigeration temperature of the sample.

[0043] The above are merely embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are included in the scope of the claims of the present invention to be approved.
