[0057] Working principle of the invention:

[0058] The mixing mechanism 3 employs a combination of clamping component 31 and mixing component 32. Clamping component 31 uses electromagnetic and elastic elements to achieve precise clamping and positioning, ensuring the stability of test tube 22 during mixing and preventing displacement. The coordinated operation of the crank plate 321, hinge block 322, air bladder, and lifting cylinder 324 in mixing component 32 makes the mixing process more uniform and improves the accuracy of sample detection. In particular, the hinge block 322 and air bladder allow for precise adjustment under different forces, further optimizing sample processing. The innovation of the temperature control mechanism 5 lies in its efficient hot and cold water circulation system. The stirring angle is controlled by varying the depth to which test tubes 22 are embedded in the upper casing 12. A turbidimeter 41 ensures that the detection area below test tubes 22 remains dark and the culture medium is not cloudy, allowing for normal operation. Transmitters 42 and receivers 43 are located on either side of test tubes 22. By detecting the degree of light reactivity of the liquid, damaged reagents, test reagents, and reagents that have completed testing are distinguished, thus controlling the embedding depth of test tubes 22. The cold water chamber 131 and hot water chamber 132 are configured, and multiple valves, including a cold water valve 54 and a hot water valve 52, control the temperature. The heating tube 51, arranged in a serpentine pattern, ensures uniform heating of the hot water, resulting in excellent temperature control. The coordination of the cold and hot water circulation valves 53 enables precise adjustment of the temperature control zone, guaranteeing the constant temperature environment required during sample testing. This combination of designs gives the equipment excellent temperature control capabilities and detection accuracy during operation, improving the reliability and consistency of the test results.
