[0002] In the field of bio-extraction, centrifuges are crucial equipment used to separate biological samples of different densities, such as cells, proteins, and nucleic acids. During the use of centrifuges, personnel often need to clean the interior regularly. However, during routine cleaning, due to the small gap between the centrifuge's rotor and the inner tank, conventional cleaning tools are difficult to penetrate, making it difficult to completely remove dirt and residual biological samples. Therefore, personnel often need to disassemble the rotor using tools. The disassembly operation is quite cumbersome, which greatly increases the difficulty of daily cleaning. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] The components in this application, such as the housing 1, control panel 2, heat dissipation hole 3, angle rotor 4, inner liner 5, protective cover 6, fixing frame 7, stepper motor 8, first pulley 9, belt 10, push rod 11, rotating shaft 12, second pulley 13, reinforcing plate 14, spline shaft 15, spline sleeve 16, fixing cylinder 17, pressing block 18, groove 19, annular groove 20, clamping plate 21, and pressure spring 22, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0022] Example 1:

[0023] Please see Figures 1-5 As shown, this utility model provides a centrifuge device for biological extraction, including a shell 1. An inner liner 5 is fixedly installed in the middle of the inner cavity of the shell 1. A rotating shaft 12 is movably connected between the middle of the bottom of the inner liner 5 and the middle of the bottom of the inner cavity of the shell 1 via a bearing. A spline shaft 15 is fixedly connected to the top of the rotating shaft 12. An annular groove 20 is opened on the top of the spline shaft 15. A spline sleeve 16 is engaged with the surface of the spline shaft 15. A fixed cylinder 17 is fixedly connected to the outer surface of the spline sleeve 16. An angle rotor 4 is fixedly connected to the outer surface of the fixed cylinder 17. Push rods 11 are slidably connected to the upper ends of both sides of the fixed cylinder 17. A pressure spring 22 is fixedly connected between the surface of the push rod 11 and the upper end of the inner cavity of the fixed cylinder 17. A clamping plate 21 is fixedly connected to the bottom of the two push rods 11 that are close to each other. The lower end of the clamping plate 21 is movably connected to the surface of the annular groove 20.

[0024] In this technical solution, when personnel need to clean the inside of the centrifuge, they can press the push rods 11 on both sides to move them closer to each other. This moves the L-shaped clamping plate 21 and stretches the pressure spring 22 inside the fixed cylinder 17 until the L-shaped clamping plate 21 can disengage from the annular groove 20, thus limiting the vertical contact between the fixed cylinder 17 and the spline shaft 15. Then, personnel can pull the fixed cylinder 17 and the angle rotor 4 upwards, allowing the spline sleeve 16 to be removed from the surface of the spline shaft 15. Personnel can then clean the inside of the inner tank 5. The overall operation is convenient and quick, greatly facilitating daily cleaning and maintenance.

[0027] In this technical solution, the stepper motor 8 is supported and fixed by the fixed frame 7. With the stepper motor 8, the first pulley 9, the belt 10 and the second pulley 13, the first pulley 9 can be rotated by the stepper motor 8, and the second pulley 13, the rotating shaft 12, the spline shaft 15, the spline sleeve 16, the fixed cylinder 17 and the angle rotor 4 can be rotated by the belt 10, so as to achieve the centrifugation operation of the centrifuge tube placed on the angle rotor 4.

[0028] Example 3:

[0029] Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, a reinforcing plate 14 is fixedly connected between the outer surface of the fixed cylinder 17 and the bottom of the angle rotor 4. A centrifuge tube is placed on the top of the angle rotor 4. A pressing block 18 is fixedly connected to the side of the two push rods 11 that are far apart from each other. Grooves 19 are provided at both ends of the top of the fixed cylinder 17. The surface of the pressing block 18 is slidably connected to the surface of the groove 19. A protective cover 6 is movably connected to the top of the housing 1 through a hinge. A control panel 2 is fixedly installed on the upper end of the front surface of the housing 1. Heat dissipation holes 3 are provided on both sides of the housing 1. Rubber support seats are fixedly connected around the bottom of the outer surface of the housing 1. The push rod 11 is U-shaped and the clamping plate 21 is L-shaped.

[0030] In this technical solution, the reinforcement plate 14 effectively improves the connection strength between the fixed cylinder 17 and the angle rotor 4. The pressing block 18 facilitates the pressing and pushing of the push rod 11 by personnel. The protective cover 6 facilitates the protection of the top of the housing 1 by personnel. The heat dissipation hole 3 facilitates the dissipation of heat inside the housing 1 to the outside. The rubber support seat provides support for the bottom of the housing 1.
