[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0025] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0026] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0027] The utility model provides a small reagent refrigeration device and a sample analyzer, such as Figures 1 to 4 As shown, a small reagent refrigeration device includes a refrigerator 1 and a cooling component 2. The refrigerator 1 is provided with a refrigerated compartment 11 for limiting reagent bottles. The refrigerated compartment 11 is tilted, and the tilt angle of the refrigerated compartment 11 is 5-15°. In this embodiment, the tilt angle of the refrigerated compartment 11 is 10.5°, which helps to place the reagent bottles firmly and facilitate their use, and can make the reagents in the reagent bottles tilt to one side, and the residual reagents can be gathered on one side of the reagent bottle, so that the dead space capacity is lower and more reagents are saved.

[0028] In this embodiment, the refrigerator 1 is manufactured by injection molding and mass production is performed through molds, which can effectively reduce costs.

[0029] In other embodiments, a partition or limiting structure such as a groove or partition may be provided in the cold storage chamber 11 to ensure that the reagent bottles do not collide with or roll against each other during the refrigeration process.

[0030] In this embodiment, the cooling component 2 includes a refrigerator 21 and an air duct 22. The air duct 22 is provided with a heat sink 23 and a fan 24. The refrigerator 21, the air duct 22, the heat sink 23, and the fan 24 cooperate to cool the cold storage box 1. In this embodiment, the refrigerator 21 is a refrigerator 21 based on the Peltier effect. The refrigerator 21 includes a heat absorption end 211 and a heat release end 212, which are used to absorb and release heat, respectively. The heat absorption end 211 is electrically connected to the cold storage compartment 11, and the heat release end 212 is electrically connected to the heat sink 23.

[0031] In this embodiment, the heat absorbing end 211 is electrically connected to the refrigerated compartment 11 and is configured to absorb heat within the refrigerated compartment 11, thereby lowering its temperature. The heat releasing end 212 is electrically connected to the heat sink 23 and is configured to transfer the absorbed heat to the heat sink 23 for further dissipation via the fan 24. In this embodiment, the air duct 22 serves as a heat transfer channel, ensuring that heat can be efficiently transferred from the heat releasing end 212 to the heat sink 23 and effectively reducing heat loss during the transfer process. The heat sink 23 is a fin-type heat sink 23, which is configured to increase the heat dissipation area of ​​the heat releasing end 212, thereby effectively transferring heat to the surrounding air and improving heat dissipation efficiency. The fan 24 corresponds to the heat sink 23 and is configured to accelerate the flow of air around the heat sink 23, thereby improving heat dissipation efficiency.

[0032] In this embodiment, the refrigerator 21 is located at the bottom of the cold storage box 1. It should be noted that the refrigerator 21 based on the Peltier effect is an existing technology and is a solid refrigeration technology with the advantages of small size, no noise, no vibration, etc., and has higher refrigeration efficiency and relatively low energy consumption. It can directly convert electrical energy into heat energy transfer without the need for additional refrigerants or compressors. Those skilled in the art should be clear about its structure, principle and usage method, etc., and no specific description is given here. The refrigerator 21 can be used according to actual conditions.

[0033] In this embodiment, the outer walls of the refrigerator 1 and refrigerator 21 are both wrapped with insulation 12. Insulation 12 is a highly effective thermal insulation material whose low thermal conductivity effectively prevents heat from transferring through the outer walls of the refrigerator 1 and refrigerator 21. When the interior of the refrigerator 1 needs to be kept cool, insulation 12 reduces the impact of high external temperatures on the internal temperature of the refrigerator 1, thereby reducing energy consumption and improving refrigeration efficiency. It also mitigates temperature fluctuations within the refrigerator 1, enabling precise control of the temperature of reagents or samples to ensure their quality and performance.

[0034] In this embodiment, a support structure 3 is provided at the bottom of the refrigerator 1. The support structure 3 includes partitions 31 and pillars 32 distributed sequentially along the side away from the refrigerator 1. In this embodiment, the ends of the partitions 31 are respectively interlocked with the refrigerator 1 and the pillars 32. The refrigerator 1 and the pillars 32 are both made of metal, which has the advantages of high strength, strong load-bearing capacity, and good stability. It should be noted that if the refrigerator 1 and the pillars 32 are in direct contact, the heat transfer rate will be accelerated. In this embodiment, the partitions 31 are made of plastic, which can reduce the heat transfer rate, reduce heat loss, and further reduce the impact of the external environment on the temperature of the inner wall of the refrigerator 1.

[0035] In this embodiment, a liquid flow outlet 13 is provided at the bottom of the cold storage box 1, and the liquid flow outlet 13 is interconnected with the cold storage compartment 11. When the temperature of the cold storage compartment 11 is too low, condensed water will be generated, and the condensed water will be discharged from the cold storage box 1 through the liquid flow outlet 13, which can reduce the liquid accumulation in the cold storage compartment 11. At the same time, when the reagent is accidentally spilled into the cold storage compartment 11, it can also be discharged through the liquid flow outlet 13.

[0036] In this embodiment, the refrigerator 1 is hingedly connected to a compartment lid 14, which allows the compartment lid 14 to be freely opened and closed within a certain range. The compartment lid 14 completely covers the opening of the refrigerated compartment 11, preventing impurities such as outside air, dust, and moisture from entering the interior of the refrigerated compartment 11. In other embodiments, to improve the sealing performance of the compartment lid 14, a sealing strip or sealing gasket can be provided between the compartment lid 14 and the main body of the refrigerator 1 to further prevent outside air from entering the interior of the refrigerated compartment 11 through the gap, thereby effectively improving refrigeration efficiency.

[0037] A sample analyzer includes a main body, a small reagent refrigeration device, and a sample analyzer as described above. Integrating the small reagent refrigeration device and the sample analyzer into the sample analyzer facilitates storage and access of reagents, helps shorten analysis time and improve analysis efficiency, and helps maintain the activity and stability of the reagents, thereby improving the accuracy and reliability of the analysis results. In this embodiment, the sample analyzer is a hematology analyzer.

[0038] The utility model provides a small reagent refrigeration device and a sample analyzer. In the small reagent refrigeration device, the reagent bottles are placed at an angle in the refrigeration chamber 11, so that the reagents in the reagent bottles can be tilted to one side, and the residual reagents can be gathered on one side of the reagent bottles, so that the dead space capacity is lower and the reagents are saved more. The small reagent refrigeration device can provide a stable low-temperature environment to ensure that the reagents are not affected by external temperature fluctuations during storage, thereby maintaining their activity and stability.
