Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a centrifuge device. Background Technology

[0002] When preparing cell blocks using the agar method, it is often necessary to go through processes such as melting, temperature control, mixing, centrifugation, and cooling.

[0003] Existing centrifuge devices do not integrate heating devices, making it impossible to achieve temperature control and switching of centrifugation functions. Centrifuge tubes need to be transferred between different devices, increasing transfer time and hindering the improvement of detection efficiency.

[0004] Based on the above problems, there are currently centrifuge devices with heating components. For example, Chinese Patent No. CN211190614U discloses a centrifuge for biomedicine, and Chinese Patent No. CN221797491U discloses a high-speed centrifuge mechanism for microbial purification. However, these devices all achieve overall heating of the space where the centrifuge tubes are placed, and cannot concentrate the heat energy at the bottom of the centrifuge tubes, resulting in energy waste.

[0005] Chinese patent CN214021400U discloses a centrifuge device for medical testing. This device combines water bath heating with centrifugation. However, water bath heating can cause water evaporation, which in turn affects the analytical results of the test samples.

[0036] Beneficial effects:

[0038] 2. This device integrates heating and centrifugation functions. Users only need to add the sample and agar, and the equipment can then perform subsequent processes such as heating, melting, isothermal control, centrifugation, and cooling. This reduces the opportunity for operators to directly contact high-temperature agar and biological samples, lowering the risk of burns and biocontamination. It reduces the workload and skill dependence of operators, significantly improves experimental efficiency, and ensures high consistency and reproducibility of results.

[0039] 3. The lifting mechanism drives the annular electric heating cover to move up and down. When the centrifuge disc is rotating, the annular electric heating cover moves downward to avoid the centrifuge disc. When the centrifuge disc stops running, the annular electric heating cover rises to achieve sample heating control. Attached Figure Description
