Abstract
Description
Technical Field
[0001] This utility model relates to the field of fully automated biochemical analyzer technology, and in particular to a constant temperature structure for a fully automated biochemical analyzer that can prevent the loss of constant temperature liquid. Background Technology
[0002] Fully automated biochemical analyzers are instruments used to detect and analyze biochemical substances. They are important medical devices that provide information for clinical diagnosis, treatment, prognosis, and health status. Since temperature has a significant impact on the reaction results during biochemical reactions, the sensitivity and accuracy of the temperature control system directly affect the measurement results. Therefore, the temperature control structure is an indispensable and important system structure in fully automated biochemical analyzers.
[0003] However, most of the existing fully automated biochemical instruments use air baths or traditional water baths for their temperature control, which generally result in poor overall stability. Furthermore, traditional water bath temperature control structures are prone to leakage of the temperature control liquid during repeated heating or cooling operations because the liquid in the temperature control bath remains stagnant for a long time and cannot flow. This significantly affects the overall performance and work efficiency.
[0004] Based on this, this utility model proposes a constant temperature structure for a fully automated biochemical analyzer that can prevent the loss of constant temperature liquid to solve the above problems. Utility Model Content

[0014] By incorporating heating bends and heating components, as well as cooling bends and cooling components, the temperature control of the constant temperature liquid in this structure can be directly achieved within the constant temperature liquid carrying tank. This avoids structural impact on the constant temperature bath and interference with its normal operation, effectively improving the overall stability of the structure.

The thermostatic liquid carrying tank 3 is a hollow tank structure. A liquid filling pipe 13 is pre-set at the upper end of the outer side of the thermostatic liquid carrying tank 3. The liquid filling pipe 13 is interconnected with the inside of the thermostatic liquid carrying tank 3. The constant temperature liquid carrying tank 3 is connected to the outside of the liquid filling pipe 13, and a liquid filling valve 14 is movably installed on the outside of the liquid filling pipe 13. A drain port 17 is pre-set on the side of the bottom of the constant temperature liquid carrying tank 3, and a drain valve 18 is movably installed on the outside of the drain port 17. A heating component 8 is fixedly installed on one side of the upper end of the constant temperature liquid carrying tank 3, and a cooling component 9 is fixedly installed on the other side of the upper end of the constant temperature liquid carrying tank 3. A heating bend 10 is spirally covered on the outside of the constant temperature liquid carrying tank 3, and the heating bend 10 and the heating component 8 are electrically connected to each other.

Ensure that the drain valve 18 is closed. During normal operation, the constant temperature liquid inside the constant temperature liquid carrier tank 3 can be pumped into the constant temperature bath 2 through the inlet pump pipe 15 and the circulation inlet hole 4.

The thermostat 6... The system can provide real-time feedback on the internal temperature of the constant temperature bath 2, allowing for the activation of the heating component 8 and the cooling component 9. The heating bend 10 and the cooling bend 11 are used respectively to heat or cool the constant temperature liquid inside the constant temperature liquid carrier tank 3, thus appropriately adjusting the temperature to meet the requirements of the reaction plate 1. The overall circulation process is continuous and smooth, facilitating temperature control.
