High-speed centrifuges are suitable for the rapid separation and synthesis of trace elements. They utilize the differences in precipitation rates of different substances in a centrifugal force field to achieve sample analysis and separation.

[0003] Existing centrifuges are often limited in functionality and have few additional features, resulting in underutilization of internal space and wasted resources. Furthermore, the handling of reagents is inconvenient for operators, leading to time-consuming operations, low efficiency, and significant temperature fluctuations in reagents during operation, which greatly affects the accuracy of experimental data.

[0004] Therefore, it is necessary to provide a centrifuge that facilitates reagent replacement to solve the above-mentioned technical problems. Summary of the Invention

[0010] A sleeve device is movably disposed inside the rotor, and multiple sleeve devices are provided and correspond to multiple reagent storage cavities, used to restrict the reagents inside the rotor and to move the reagents.

[0011] The reagent storage device drives the reagent storage plate and the reagent to rotate. The reagent storage plate moves the reagent to the position corresponding to the rotor. The sleeve device moves to the outside of the rotor and picks up the reagent on the reagent storage plate. Then the sleeve device drives the reagent back to the rotor to work.

[0014] The reagent storage device has multiple bottom slides at the bottom, which are adapted to slide with the bottom slider. The reagent storage device is provided with a second driving component for driving the reagent storage plate to move along the bottom slides via the bottom slider.

[0015] As a further aspect of the present invention: the reagent storage plate has a through-hole, the outer wall of the reagent storage plate is provided with a third driving member, and the output end of the third driving member is provided with a control block located at the corresponding through-hole position for pushing the reagent.

[0016] As a further aspect of the present invention: the inner wall of the reagent storage plate is provided with a plurality of elastic fixing blocks for restricting the movement of reagents entering the reagent storage plate.

[0017] As a further aspect of the present invention: the outer wall of the rotor is provided with a plurality of inlets and outlets communicating with its interior, and a side sliding groove is provided in the rotor at the position corresponding to the inlets and outlets;

[0018] The bottom of the sleeve device is provided with a sliding base, and the sliding base is provided with a sliding block that is adapted to slide along the side sliding groove. The rotor is provided with a fourth driving member for driving the sleeve device to move along the side sliding groove through the sliding block.

[0019] As a further aspect of the present invention: the sleeve device has a tube wall opening, and a reagent fixing member is slidably provided inside the tube wall opening for fixing the reagent located inside the sleeve device. The sleeve device is provided with a fifth driving member that drives the reagent fixing member to move up and down along the tube wall opening.

[0020] As a further aspect of the present invention, it also includes:

[0021] An arc-shaped slide is provided on the sliding base. A slide rod is slidably arranged inside the arc-shaped slide. A movable tube wall is provided at the upper end of the slide rod to cover the opening of the sleeve device.

[0022] The bottom of the sliding base is provided with a sixth driving component, which is used to drive the moving pipe wall to slide along the arc-shaped slide rail via the slide rod.

[0023] As a further aspect of the present invention: a slide rail interlayer is provided in the side wall of the rotor, and a movable door is slidably disposed in the slide rail interlayer to seal the entrance and exit.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. When reagent needs to be filled into the rotor, this solution uses a reagent storage plate to move the reagent horizontally towards the rotor. The sleeve device inside the rotor moves outward, and the reagent storage plate pushes the reagent into the sleeve device. Then, the sleeve device pulls the reagent back into the rotor; the reagent storage plate then returns to the reagent storage device, completing the filling process. Similarly, when changing reagents, the centrifuged reagent is removed from the rotor via the sleeve device and pushed onto an empty reagent storage plate. The entire reagent storage device then rotates, causing another reagent storage plate to rotate with the reagent to be centrifuged to the position of the sleeve device, pushing the reagent back into the sleeve device. This process is repeated, providing a simple and convenient way to change reagents. This greatly reduces the need for staff to repeatedly open the centrifuge to retrieve and place reagents, saving significant time and increasing operational efficiency and automation. It also significantly reduces the risk of large temperature fluctuations caused by reagent handling, greatly improving the accuracy of experimental data and demonstrating strong practicality.

[0027] 2. In this solution, when the sleeve device is moved outside the rotor, the control block will push the reagent in the reagent storage plate into the sleeve device to complete the reagent filling; when changing the reagent, the sleeve device will move the centrifuged reagent out of the rotor, release the sleeve device itself from fixing the centrifuged reagent, and push the reagent into the reagent storage plate. Then, the reagent to be centrifuged on the other reagent storage plate will enter the sleeve device, thus completing the reagent replacement. The operation process is fast and smooth, and it is highly practical. Attached Figure Description

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figure 1-3 , Figure 5-7 and Figure 11-12 A centrifuge for easy reagent replacement includes a centrifuge body 1 with a centrifugation chamber 11 and a rotor 12 inside the centrifugation chamber 11. It also includes: a reagent storage chamber 2, multiple of which are disposed on the centrifuge body 1, for storing reagents; a reagent storage device 21, rotatably and movable within the reagent storage chamber 2, containing multiple horizontally movable reagent storage plates 213 for fixing and moving reagents; and a sleeve device 3, movably disposed within the rotor 12, with multiple devices corresponding to the multiple reagent storage chambers 2, for restricting reagents within the rotor 12 and moving reagents. The reagent storage device 21 rotates the reagent storage plates 213 and the reagents, the reagent storage plates 213 move the reagents to the corresponding positions on the rotor 12, the sleeve device 3 moves outside the rotor 12 and collects the reagents from the reagent storage plates 213, and then the sleeve device 3 moves the reagents back to the rotor 12 for operation.

[0047] In use, when the reagent is in storage or the rotor 12 is in operation, the reagent storage device 21 in the reagent storage chamber 2 will rotate to an appropriate position, so that the reagent storage device 21 is not connected to the rotor 12, thus avoiding affecting the normal operation of the rotor 12 in the centrifuge chamber 11. At this time, the reagent will be stored on the reagent storage plate 213 in the reagent storage device 21.

[0048] When reagent needs to be filled into rotor 12, after rotor 12 stops rotating, reagent storage device 21 in reagent storage chamber 2 rotates to an appropriate position to communicate with rotor 12. Then, reagent is moved horizontally towards rotor 12 via reagent storage plate 213. The sleeve device 3 inside rotor 12 moves outwards from rotor 12, i.e., towards reagent storage chamber 2. After moving to the designated position, reagent storage plate 213 pushes the reagent onto it, pushing it into sleeve device 3. Sleeve device 3 then restricts and fixes the reagent, and then the sleeve device 3 moves the reagent back into rotor 12. Reagent storage plate 213 then retracts into reagent storage device 21, which rotates to an appropriate position to seal reagent storage chamber 2. At this point, reagent filling is complete, and centrifuge body 1 can operate normally. Similarly, when changing reagents, as described above, the reagent storage plate 213 without reagents moves towards the rotor 12 until it reaches the designated point. The centrifuged reagent is then removed from the rotor 12 via the sleeve device 3 and pushed onto the reagent storage plate 213. After the reagent is secured by the reagent storage plate 213, it moves the reagent back into the reagent storage device 21, causing the reagent storage device 21 to rotate. At this point, the reagent storage plate 213 in another location, carrying the reagent to be centrifuged, is positioned in the sleeve device 3. The subsequent steps are the same as described above: the reagent to be centrifuged is pushed back into the sleeve device 3, and the sleeve device 3 moves the reagent back into the rotor 12 for the next centrifugation. This process is repeated to perform the replacement operation, making reagent replacement simple and convenient. This greatly avoids the need for staff to open the centrifuge and repeatedly retrieve and place reagents, saving a significant amount of time and significantly improving operational efficiency and automation. It also greatly reduces the large temperature changes that occur when retrieving and placing reagents, greatly improving the accuracy of experimental data and demonstrating strong practicality.

[0049] A rotating shaft 13 is rotatably mounted inside the centrifuge chamber 11 via bearings. The rotor 12 is connected to the rotating shaft 13. A drive motor 14 is installed inside the centrifuge body 1, and its output end is connected to the bottom of the rotating shaft 13. The drive motor 14 drives the rotating shaft 13 and the rotor 12 to rotate, thereby realizing the centrifugal motion of the reagents inside the rotor 12.

[0050] In this embodiment, preferably, please refer to [reference needed]. Figure 3 , Figure 5-7 and Figure 10The reagent storage chamber 2 has a reagent transfer port 22 connected to the centrifuge chamber 11. A first driving component, which drives the reagent storage device 21 to rotate, is located at the bottom of the reagent storage chamber 2. In this application, the first driving component can be a servo motor. Openings 211 are provided at the corresponding positions of each reagent storage plate 213 on the side wall of the reagent storage device 21. The reagent transfer port 22 facilitates communication with the rotor 12, allowing for the exchange and placement of reagents. The first driving component drives the reagent storage device 21 to rotate within the reagent storage chamber 2. The rotation of the reagent storage device 21 causes the reagent storage plates 213 and the reagents on them to rotate, and also changes the direction of the openings 211. When reagents are being removed or replaced, the openings 211 rotate to the position of the reagent transfer port 22 and connect with it. After the reagents have been removed or replaced, during centrifugation, the openings 211 rotate to the inner wall of the reagent storage chamber 2, no longer communicating with the reagent transfer port 22, thus sealing the reagent storage chamber 2.

[0051] In this embodiment, preferably, please refer to [reference needed]. Figure 7-9 and Figure 10 The reagent storage plate 213 has a bottom fixing platform 218 at its bottom, and a bottom slider 217 is provided on the side wall of the bottom fixing platform 218. The reagent storage device 21 has multiple bottom slides 212 at its bottom, which slide and adapt to the bottom sliders 217. A second driving component is provided on the reagent storage device 21. In this application, the second driving component can be an electric slide rail or an electric telescopic rod, used to drive the reagent storage plate 213 to move along the bottom slides 212 via the bottom sliders 217. The second driving component can drive the reagent storage plate 213 to move, and the reagent storage plate 213 moves along the bottom slides 212 via the bottom sliders 217, thereby realizing the horizontal movement of the reagent storage plate 213, that is, moving towards or away from the opening 211.

[0052] In this embodiment, preferably, please refer to [reference needed]. Figure 7-9 The reagent storage plate 213 has a through-hole 215, and a third driving member 219 is provided on the outer wall of the reagent storage plate 213. The third driving member 219 in this application can be a motor. The output end of the third driving member 219 is provided with a control block 216, which is located at the corresponding through-hole 215 and is used to push the reagent. The third driving member 219 drives the control block 216 to rotate. When the control block 216 rotates, its end will gradually squeeze and push the reagent in the reagent storage plate 213, and finally push the reagent out of the reagent storage plate 213.

[0053] In this embodiment, preferably, please refer to [reference needed]. Figure 7 and Figure 9The inner wall of the reagent storage plate 213 is provided with multiple elastic fixing blocks 214 to restrict the movement of reagents entering the reagent storage plate 213. The elastic fixing blocks 214 restrict and fix the reagents. When the control block 216 pushes the reagent, the reagent also squeezes the elastic fixing blocks 214. Finally, after the reagent is removed from the reagent storage plate 213, it is no longer restricted or fixed by the elastic fixing blocks 214. When the sleeve device 3 pushes the reagent into the reagent storage plate 213, the elastic fixing blocks 214 also fix the reagent, thus completing the reagent transfer. The operation process is simple and quick.

[0054] In this embodiment, preferably, please refer to [reference needed]. Figure 11-14 The outer wall of the rotor 12 is provided with multiple inlets and outlets 121 that communicate with its interior. A side sliding groove 124 is provided at the corresponding position of the inlet and outlet 121 inside the rotor 12. A sliding base 31 is provided at the bottom of the sleeve device 3. A sliding block 32 that is slidably adapted to the side sliding groove 124 is provided on the sliding base 31. A fourth driving member is provided inside the rotor 12 to drive the sleeve device 3 to move along the side sliding groove 124 through the sliding block 32. The fourth driving member of this application can be an electric slide rail, an electric telescopic rod, or a gear rack, etc. After the rotor 12 stops rotating, the inlet / outlet 121 on the rotor 12 will correspond to the positions of each reagent transfer port 22. Then, the fourth driving component drives the sleeve device 3 and the sliding base 31 to move along the side sliding groove 124 via the sliding block 32. This allows the sleeve device 3 and the reagent inside it to move away from or towards the center of the rotor 12. When the sleeve device 3 and the reagent are away from the center of the rotor 12, it is in the state of filling or discharging reagent. When the sleeve device 3 and the reagent are close to the center of the rotor 12, it is in the state of filling reagent and returning for centrifugation, or stopping use after the work is completed. When the sleeve device 3 moves to the outside of the rotor 12, the control block 216 will push the reagent in the reagent storage plate 213 into the sleeve device 3 to complete the reagent filling. When replacing, the sleeve device 3 will move the reagent out of the rotor 12. After releasing the sleeve device 3 from fixing the reagent, it will push the reagent into the reagent storage plate 213 to complete the reagent replacement. The operation process is fast and smooth.

[0055] In this embodiment, preferably, please refer to [reference needed]. Figure 12-14The sleeve device 3 has a tube wall opening 36, and a reagent fixing member 37 is slidably disposed within the tube wall opening 36 to fix the reagent located inside the sleeve device 3. The sleeve device 3 is provided with a fifth driving member 38 that drives the reagent fixing member 37 to move up and down along the tube wall opening 36. The fifth driving member 38 in this application can be an electric slide rail, an electric telescopic rod, or a gear rack structure. When changing the filling reagent, the rotor 12 will always position the tube wall opening 36 at the inlet / outlet 121 position. When the reagent storage plate 213 pushes the reagent into the sleeve device 3 through the tube wall opening 36, the fifth driving member 38 will drive the reagent fixing member 37 to move down along the tube wall opening 36, and finally fix the reagent through the reagent fixing member 37. When the reagent is centrifuged and needs to be removed, the fifth driving member 38 will drive the reagent fixing member 37 to move up along the tube wall opening 36, thereby releasing the fixation of the reagent.

[0056] In this embodiment, preferably, please refer to [reference needed]. Figure 12-14 It also includes: an arc-shaped slide 35, which is provided on the sliding base 31. A slide rod 39 is slidably arranged in the arc-shaped slide 35. A movable tube wall 33 is provided at the upper end of the slide rod 39 to cover the opening of the sleeve device 3. A sixth driving member 34 is provided at the bottom of the sliding base 31 to drive the movable tube wall 33 to slide along the arc-shaped slide 35 through the slide rod 39. The sixth driving member 34 in this application adopts an electric slide rail or a gear rack structure. The sixth driving member 34 can drive the movable tube wall 33 to slide along the arc-shaped slide 35 through the slide rod 39, thereby opening or closing the opening of the sleeve device 3. Before centrifugation, the sleeve device 3 is sealed by the movable tube wall 33. When the reagent is discharged after centrifugation, the movable tube wall 33 is opened again, so that the reagent can be removed from the opening of the sleeve device 3.

[0057] In this embodiment, preferably, please refer to [reference needed]. Figure 11 and 15The rotor 12 has a slide rail interlayer 122 in the side wall, and a movable door 123 is slidably disposed in the slide rail interlayer 122 to block the entrance 121. The bottom of the corresponding slide rail interlayer 122 on the side wall of the rotor 12 is provided with a slide rail for the movable door 123 to move, and a seventh driving member is provided in the slide rail to drive the movable door 123 to move. The seventh driving member in this application can be an electric slide rail or a gear rack structure. When filling the rotor 12 with reagent or changing the reagent, the seventh drive unit drives the movable door 123 to slide along the slide rail and into the slide rail interlayer 122. At this time, the movable door 123 no longer blocks the inlet and outlet 121, and the reagent can be removed from the inlet and outlet 121. When the rotor 12 is about to perform centrifugal operation, the seventh drive unit drives the movable door 123 to slide along the slide rail and out of the slide rail interlayer 122. The movable door 123 blocks the inlet and outlet 121, so that the rotor 12 can perform centrifugal operation smoothly.
