[0038] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0039] Combine Figures 1 to 8 As shown, the embodiment of the present disclosure provides an angle rotor, which includes a rotor body 10. The rotor body 10 defines a plurality of receiving holes 101 spaced apart along the circumference of the rotor body 10. The receiving holes 101 are used to receive the sample container 60. Figure 2 and Figure 4 As shown, a weight-reducing hole 102 is configured in the rotor body 10 between two adjacent receiving holes 101 .

[0040] In the disclosed embodiment, the receiving holes 101 are used to accommodate the sample container 60, allowing the sample container 60 to rotate with the rotor body 10 to centrifuge the reagents within the sample container 60. The rotor body 10 between two adjacent receiving holes 101 is deburred to form weight-reducing holes 102. This reduces the weight of the angle rotor, ensuring that the rotor meets the load capacity of the centrifuge's drive device, allowing the centrifuge to easily reach the desired speed, improving the centrifugal efficiency, and ensuring the separation of reagents. Furthermore, the reduced weight of the angle rotor makes it easier for users to handle and enhances operational convenience.

[0041] Optionally, the cross-sectional area of ​​the receiving hole 101 gradually increases from top to bottom, which can ensure the strength of the rotor body 10 and prevent the rotor body 10 from being damaged.

[0042] Optionally, the bottom of the rotor body 10 is recessed upward to form a hollow structure 103 .

[0043] In the embodiment of the present disclosure, a hollow structure 103 is also constructed inside the rotor body 10, which can further reduce the weight of the angle rotor and improve the centrifugal efficiency.

[0044] In the prior art, angle rotors cannot reach the preset speed of 10,000 rpm due to excessive load, and can only reach 8,000 rpm due to the limited load capacity of the centrifuge motor. The angle rotor of the disclosed embodiment reduces its weight through the weight-reducing holes 102 and hollow structure 103, ensuring that the angle rotor meets the load capacity of the centrifuge motor, easily reaching the preset speed, and improving centrifugal efficiency.

[0045] Alternatively, as Figure 3 and Figure 6 As shown, the lower portion of the hollow structure 103 has a first opening, and a plurality of receiving holes 101 are arranged on the outer side of the hollow structure 103 along the circumference of the hollow structure 103. The angular rotor also includes an inner sleeve 20, which is located in the hollow structure 103. The upper end of the inner sleeve 20 is connected to the rotor body 10, and the lower end of the inner sleeve 20 is covered on the first opening to close the first opening.

[0046] In the disclosed embodiment, the inner sleeve 20 is located in the hollow structure 103, which facilitates the arrangement of the inner sleeve 20. The inner sleeve 20 can not only cooperate with the drive device connected to the centrifuge, but the inner sleeve 20 can also cover the first opening, so that the lower end of the hollow structure 103 is closed to prevent condensation water from accumulating on the inner wall of the structure.

[0047] Alternatively, as Figure 8 As shown, the inner sleeve 20 includes a connecting sleeve 201 and a sealing cover 202. The connecting sleeve 201 is located within the hollow structure 103, extends in the height direction, and is connected to the rotor body 10; the sealing cover 202 is connected below the connecting sleeve 201 and is located below the first opening to close the first opening. The sealing cover 202 and the connecting sleeve 201 are an integrated structure.

[0048] In the disclosed embodiment, the inner sleeve 20 includes two parts, and the connecting sleeve 201 is used to connect with the rotor body 10 to realize the connection between the driving device of the centrifuge and the rotor. The sealing cover 202 is used to close the first opening to seal the lower end of the hollow structure 103. In addition, the sealing cover 202 and the connecting sleeve 201 are an integrated structure, which reduces the assembly process of the sleeve and improves production efficiency. In addition, the hollow structure 103 is sealed by the inner sleeve 20, which can reduce or avoid the contact between the hollow structure 103 and the external gas, reduce the generation of condensed water, and thus avoid the accumulation of condensed water.

[0049] Optionally, the angle rotor further includes a first sealing strip 203 , which is provided between the lower end of the shaft sleeve and the rotor body 10 .

[0050] In the disclosed embodiment, first sealing strip 203 seals between the lower end of the sleeve and rotor body 10, completely sealing hollow structure 103 and preventing condensation from forming on the inner wall of hollow structure 103, which could lead to condensation accumulation. Furthermore, the sealing between rotor body 10 and inner sleeve 20 by first sealing strip 203 reduces wind resistance and noise.

[0051] Optionally, the first opening is circular, and the first sealing strip 203 extends in a ring shape along the circumference of the first opening to circumferentially close the first opening, so that the hollow structure 103 is closed to prevent the hollow structure 103 from contacting the external air to generate condensed water.

[0052] Optionally, the hollow structure 103 is connected to the lower end of the lightening hole 102. In this way, the lightening hole 102 between two adjacent receiving holes 101 is removed, and the lightening hole 102 is connected to the hollow structure 103, which facilitates the processing of the lightening hole 102 and the hollow structure 103 and can effectively reduce the weight of the angular rotor.

[0053] Alternatively, as Figure 6 As shown, the rotor body 10 is also constructed with a connecting portion 104, which is located above the hollow structure 103, and a plurality of receiving holes 101 are connected to the outside of the connecting portion 104 along the circumference of the connecting portion 104; wherein the inner sleeve 20 is attached to and connected to the lower end of the connecting portion 104.

[0054] In the disclosed embodiment, the rotor body 10 is internally configured with a connecting portion 104, which is connected to the inner sides of the plurality of receiving holes 101. This ensures the strength of the rotor body 10 and prevents damage to the rotor body 10 due to a reduction in strength caused by the provision of receiving holes 101. The inner sleeve 20 fits in contact with the lower end of the connecting portion 104, thus achieving the connection between the inner sleeve 20 and the rotor body 10.

[0055] Optionally, the connecting portion 104 and the hole walls of the plurality of receiving holes 101 are an integrated structure.

[0056] Optionally, the inner sleeve 20 is configured with a first rotating hole 204, the connecting portion 104 is configured with a second rotating hole 105, the first rotating hole 204 and the second rotating hole 105 are coaxially arranged, the driving device of the centrifuge is suitable for passing through the first rotating hole 204 and the second rotating hole 105, and the angular rotor also includes a locking nut 30, which is arranged in the second rotating hole 105 and is suitable for connecting to the driving device of the centrifuge.

[0057] In the disclosed embodiment, the first rotating hole 204 of the inner sleeve 20 facilitates the passage of the rotating shaft of the centrifuge's drive device. After passing through the first rotating hole 204, the rotating shaft of the drive device can extend into the second rotating hole 105. A locking nut 30 is provided in the second rotating hole 105. The locking nut 30 can secure the rotating shaft of the drive device, ensuring that the bearing remains stable in its working position. The locking nut 30 can also prevent the rotating shaft from shifting or loosening due to vibration or impact during operation. Axial displacement is prevented: When the drive device is operating, the angular rotor generates axial forces, which can cause axial displacement of the bearing. By locking the rotating shaft, the locking nut 30 can effectively prevent the rotating shaft from moving axially, ensuring that the angular rotor operates in the correct position.

[0058] Optionally, the locking nut is configured with an internal thread that can cooperate with a rotating shaft of a driving device of the centrifuge, and the rotating shaft is provided with an external thread, so that the rotating shaft can be connected to the locking nut 30.

[0059] Alternatively, as Figure 6 As shown, the angle rotor further includes a flange 40 and a fastener 402 . The flange 40 is disposed above the connecting portion 104 . The fastener 402 passes through the flange 40 , the connecting portion 104 and the inner sleeve 20 in sequence to connect the flange 40 , the rotor body 10 and the inner sleeve 20 .

[0060] In the embodiment of the present disclosure, the flange 40 is arranged above the connecting portion 104, and the inner sleeve 20 is located below the connecting portion 104, so that the fastener 402 can pass through the flange 40, the rotor body 10 and the inner sleeve 20 in sequence to connect the three together, thereby improving the structural stability of the angle rotor so that the entire angle rotor can rotate more stably.

[0061] Optionally, the flange 40 is provided with a plurality of first screw holes, which are sequentially spaced along the circumference of the flange body, and the inner sleeve 20 is provided with second screw holes, the number of which is the same as the number of the first screw holes and corresponds one-to-one. This can further enhance the connection strength between the rotor body 10, the flange 40, and the inner sleeve 20.

[0062] For example, the number of the first screw holes is six.

[0063] Optionally, the flange 40 is provided with a third rotating hole, which is coaxially arranged with the first rotating hole 204 and the second rotating hole 105, and the third rotating hole is connected to the locking nut 30, so that the tightening tool can cooperate with the locking nut 30 from the third rotating hole to tighten the locking nut 30 to the rotating shaft of the driving device.

[0064] Optionally, the upper portion of the rotor body 10 has a second opening, and the angle rotor further includes a rotor cover 50 and a second sealing strip 501 . The rotor cover 50 is arranged to cover the second opening; the second sealing strip 501 is arranged at the connection between the rotor cover 50 and the rotor body 10 .

[0065] In the disclosed embodiment, the rotor cover 50 is provided at the second opening, so that it is convenient to place the sample container 60 from the second opening to the receiving hole 101. After the sample container 60 is placed, the rotor cover 50 can cover the second opening and the receiving hole 101, so that the sample container 60 will not fall out of the receiving hole 101 when the angular rotor rotates. In addition, the rotor cover 50 can reduce wind loss, thereby reducing the noise when the centrifuge is working. The second sealing strip 501 is located between the rotor cover 50 and the rotor body 10, so that the upper opening of the rotor body 10 can also be sealed to prevent the accumulation of condensed water on the inner wall of the rotor. The opening on the upper part of the rotor body 10 is also sealed, which can further reduce wind resistance and reduce noise.

[0066] Optionally, the second sealing strip 501 is annular, so as to completely seal the rotor cover 50 and the rotor body 10 from the circumferential direction.

[0067] Optionally, the rotor cover 50 is provided with a through hole, which passes through the rotor cover 50 in the thickness direction. The angle rotor also includes a rotor handle 502, which passes through the through hole. The lower end of the rotor handle 502 is connected to the rotor body 10, and the upper end of the rotor handle 502 is located above the through hole.

[0068] In the embodiment of the present disclosure, the lower end of the rotor handle 502 is connected to the rotor body 10, so that the entire rotor body 10 can be lifted by the rotor handle 502. The rotor handle 502 is easy to grasp, thereby making it easy for the user to move the angle rotor through the rotor handle 502.

[0069] Optionally, the lower end of the rotor handle 502 is connected to the flange 40. Here, the flange 40 is connected to the connecting portion 104 of the rotor body 10 via a fastener 402, so that the rotor handle 502 can be connected to the rotor body 10.

[0070] Optionally, the rotor handle 502 is snap-fitted to the flange 40 .

[0071] Optionally, a mounting cavity is internally configured at the lower end of the rotor handle 502 , and the rotor handle 502 is sleeved on the outer side of the flange 40 through the mounting cavity, and the cavity wall of the mounting cavity is snap-fitted to the flange 40 .

[0072] Optionally, the cavity wall of the installation cavity is configured with a snap-fit ​​groove 5021 , and the outer wall surface of the flange 40 is configured with a snap-fit ​​protrusion. When the rotor handle 502 is connected to the flange 40 , the snap-fit ​​protrusion is located in the snap-fit ​​groove 5021 .

[0073] Optionally, the inner wall surface of the rotor body 10 is partially recessed outward to form a liquid storage groove 503 . The liquid storage groove 503 extends along the circumference of the second opening and is located below the second sealing strip 501 .

[0074] In the disclosed embodiment, a liquid storage tank 503 is provided below the second sealing strip 501 , so that when the sample in the sample container 60 accidentally overflows, the liquid storage tank 503 can store part of the sample to prevent the sample from completely flowing downwards and affecting other components.

[0075] Optionally, the liquid storage tank 503 extends in a ring shape along the circumference of the second opening.

[0076] Alternatively, as Figure 7 As shown, the angular rotor further includes a label cover 205 and an identification device. The label cover 205 is arranged on the outer wall surface of the bottom of the inner sleeve 20; the identification device is arranged between the label cover 205 and the inner sleeve 20.

[0077] In the disclosed embodiment, a label cover 205 and an identification device are provided on the bottom wall of the inner sleeve 20 , that is, the bottom of the rotor body 10 , so as to facilitate rapid identification of different rotors.

[0078] Optionally, the identification device is provided on the label cover 205 .

[0079] Optionally, the identification device includes an RFID identification chip.

[0080] Optionally, the identification device is provided on a side of the label cover 205 facing the inner sleeve.

[0081] Optionally, the label cover 205 is detachably connected to the bottom wall of the inner sleeve 20 to facilitate disassembly and maintenance of the label cover 205 and the identification device.

[0082] Optionally, the label cover 205 and the bottom wall of the inner sleeve 20 are detachably connected by screws or the like.

[0083] Optionally, the bottom wall of the inner sleeve 20 is flush with the bottom wall of the rotor body 10, so that the bottom of the angle rotor is flat, which is convenient for placement and operation.

[0084] Optionally, the outer wall surface portion of the bottom wall of the inner sleeve 20 is recessed upward to form a label slot, and the label cover 205 is covered in the label slot, which facilitates the installation of the label cover 205 on the inner sleeve 20 .

[0085] Optionally, the bottom wall of the inner sleeve 20 is flush with the bottom wall of the label cover 205, so that the bottom of the angle rotor is entirely on the same plane, which facilitates the placement and operation of the angle rotor.

[0086] Optionally, the receiving holes 101 are tilted outward from top to bottom, creating a predetermined angle between the receiving holes 101 and the centrifuge's rotation axis. This allows the angle rotor to maintain a constant angle with the centrifuge's rotation axis. This allows the sample in the sample container 60 to be reoriented during operation. Specifically, during centrifuge acceleration, the sample layer shifts from a vertical orientation to a radial distribution, with particles settling to form zones. During the rotor's stop, the sample is reoriented to form a vertical gradient. This allows for higher rotational speeds and relative centrifugal forces, enabling more efficient sample separation.

[0087] Optionally, the angle between the receiving hole 101 and the rotating shaft of the driving device of the centrifuge is in the range of 14°-40°.

[0088] Optionally, the rotor body 10 includes a cylindrical portion 106, an expanded portion 107, and a reduced diameter portion 108, arranged sequentially from top to bottom. The outer diameter of the cylindrical portion 106 remains consistent from top to bottom, the outer diameter of the expanded portion 107 gradually increases from top to bottom, and the outer diameter of the reduced diameter portion 108 gradually decreases from top to bottom. This ensures the placement of the receiving hole 101 and increases the volume of the angular rotor.

[0089] An embodiment of the present disclosure further provides a centrifuge, which includes an angular rotor as described in any one of the above embodiments.

[0090] The centrifuge provided by the embodiment of the present disclosure includes the angular rotor of any of the above embodiments, and thus has the beneficial effects of the angular rotor of any of the above embodiments, which will not be described in detail here.

[0091] Optionally, the centrifuge includes a driving device connected to the rotor body 10 , and a rotating shaft of the driving device can be inserted into the angle rotor and pass through the angle rotor so that the angle rotor can rotate to perform centrifugal motion.

[0092] Optionally, the drive device comprises a motor.

[0093] Optionally, the centrifuge includes a housing defining a centrifugal chamber into which the angular rotor can be moved. The rotation shaft of the drive device is located at the bottom of the centrifugal chamber. When the angular rotor is moved into the centrifugal chamber, the rotation shaft of the drive device can be inserted into the first rotation hole 204 and connected to the locking nut 30.
