[0002] During the centrifugation of biological samples, multiple cycles of sample centrifugation, supernatant extraction, and reagent addition are required, depending on the sample's centrifugation requirements.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] The core of this utility model is to provide a centrifuge shaking mechanism, which can improve the efficiency of sample centrifugation and the convenience of operation.

[0032] For the specific embodiment of the centrifuge shaking mechanism provided by the present invention, please refer to Figures 1 to 7 , including: a centrifugal module 1 and a shaking module 2.

[0033] The centrifugal module 1 includes a centrifugal drive assembly and a basket assembly 109 movably connected to the side of the centrifugal drive assembly, and the basket assembly 109 is used to install the centrifuge tube 105. The centrifugal drive assembly is used to drive the basket assembly 109 to rotate and centrifuge around the rotation center line of the centrifugal drive assembly. Specifically, the centrifugal drive assembly includes a centrifugal motor 101 and a rotor 102 connected to the output end of the centrifugal motor 101, the rotation center line of the rotor 102 is specifically in the up and down direction, and the basket assembly 109 is connected to the rotor 102.

[0034] The shaking module 2 includes a shaking drive assembly and a first magnetic member connected to the shaking drive assembly, and the hanging basket assembly 109 is connected to a second magnetic member. At least one of the first magnetic member and the second magnetic member is an electromagnet 207. Figure 4 As shown, the first magnetic member is an electromagnet 207, and the second magnetic member is a metal ball 108. In other embodiments, the first magnetic member and the second magnetic member may both be electromagnets.

[0035] When the electromagnet 207 is powered on, the first magnetic member and the second magnetic member are attracted to form a transmission part, so that the shaking drive assembly can drive the hanging basket assembly 109 to oscillate through the transmission part. Specifically, when the electromagnet 207 is powered on, the ball 108 is attracted, and the first magnetic member and the second magnetic member are magnetically connected. The second magnetic member can have rotational freedom on the first magnetic member, so that the shaking module 2 can move with the hanging basket assembly 109, thereby achieving the purpose of shaking in space. When the electromagnet 207 is powered off, the first magnetic member and the second magnetic member are separated and will not interfere with the action of the centrifugal module 1. At the same time, Figure 5 As shown, the ball 108 is naturally separated from the electromagnet 207 due to gravity, and the shaking module 2 does not affect the rotational movement of the centrifugal module 1.

[0036] In this embodiment, due to the addition of a first magnetic member and a second magnetic member that can be connected and separated by magnetic attraction, the switching between centrifugal motion and shaking oscillation motion of the hanging basket assembly 109 and the centrifuge tube 105 thereon can be achieved. During centrifugal motion, the hanging basket assembly 109 can be disconnected from the shaking drive assembly, and the shaking module 2 will not interfere with the centrifugal motion of the hanging basket assembly 109. When it is necessary to shake, it is only necessary to energize the electromagnet 207, and the shaking drive assembly can be used as a driving member to drive the hanging basket assembly 109 to oscillate and shake. The device has both centrifugal and shaking functions, does not need to be transferred between different devices, is easy to operate, and can improve the efficiency of centrifugal shaking. In addition, when the first magnetic member and the second magnetic member need to be connected, as long as one of the two that is adsorbed by the electromagnet 207 is within the magnetic force range of the electromagnet 207, even without manual intervention, the adsorption of the two can be achieved, which can improve the smoothness of the connection action between the two.

[0037] Furthermore, the shake drive assembly is a linear drive assembly to drive the first magnetic member to reciprocate linearly, which facilitates planning the motion trajectory of the first magnetic member. Of course, in other embodiments, the shake drive assembly can also drive the first magnetic member to move along a circular trajectory.

[0038] Further, if Figure 3 and Figure 4 As shown, the shaking drive assembly includes a linear guide rail 206, a mounting plate 204, an eccentric disk 202 and a rotating drive member.

[0039] The rotary drive member is specifically a shake motor 203. The rotary drive member is connected to and used to drive the eccentric disk 202 to rotate. The eccentric disk 202 is provided with a cam follower 201. The cam follower 201 is arranged in parallel on one side of the rotation centerline of the rotary drive member, and the cam follower 201 is eccentrically arranged relative to the eccentric disk 202. The cam follower 201 is slidably connected to the linear slide 2041 of the mounting plate 204. The first magnetic member is provided on the mounting plate 204, and the mounting plate 204 is slidably connected to the linear guide rail 206. Specifically, a slider 205 is fixedly provided on the mounting plate 204 and slidably connected to the linear guide rail 206. The guide direction of the linear guide rail 206 is at an angle to the guide direction of the linear slide 2041.

[0040] When the rotary drive member rotates the eccentric disk 202, the cam follower 201 rotates with the eccentric disk 202 and slides within the linear guide 2041. The cam follower 201 pushes the mounting plate 204, driving the mounting plate 204 and the first magnetic member to reciprocate linearly on the linear guide 206. The coordination of the rotary drive member and the cam mechanism allows for more flexible design of the movement direction of the first magnetic member, improving the smoothness of its movement. Of course, in other embodiments, linear motors, hydraulic cylinders, etc. may also be directly used.

[0041] Among them, the shaking module 2 can be installed on other modules or equipment according to structural requirements. Specifically, each basket assembly 109 can be equipped with a shaking module 2. When the basket assembly 109 is centrifugal, the corresponding shaking module 2 rotates synchronously around the rotation center line of the centrifugal drive assembly. Alternatively, each shaking module 2 is fixed and stops at the set relationship of the corresponding shaking module 2 in the circumferential direction when the centrifugal movement of the basket assembly 109 ends.

[0042] Furthermore, if Figure 2 、 Figure 3 and Figure 4 As shown, the basket assembly 109 is hinged to the centrifugal drive assembly via a first rotation axis 110. The first rotation axis 110 extends tangentially to the circular motion of the centrifugal drive assembly, and the rotation centerline of the first rotation axis 110 is perpendicular to the rotation centerline of the centrifugal drive assembly. The basket assembly 109 performs centrifugal motion around the first rotation axis 110, wherein the centrifuge tube 105 is placed in the basket frame 104. After the basket assembly 109 centrifuges, based on the direction of the first rotation axis 110, the bottom end of the basket assembly 109 continuously moves away from the rotation centerline of the centrifugal drive assembly, and eventually the basket assembly 109 can be changed from a vertical state to a horizontal state.

[0043] Furthermore, if Figure 2As shown, the hanging basket assembly 109 includes a hanging basket 103, a hanging basket frame 104, and a second rotating shaft 111. The hanging basket 103 is hinged to the centrifugal drive assembly via a first rotating shaft 110, and the hanging basket frame 104 is hinged to the hanging basket 103 via a second rotating shaft 111. The second rotating shaft 111 is angled with the first rotating shaft 110, and can be perpendicular to each other. The first rotating shaft 110 and the second rotating shaft 111 are respectively perpendicular to the rotation centerline of the centrifugal drive assembly. The provision of the second rotating shaft 111 increases the number of degrees of freedom of movement of the centrifuge tube 105 within the hanging basket assembly.

[0044] Further, if Figure 4 As shown, the hanging basket assembly 109 also includes a connecting rod mechanism, a second magnetic component is provided at the bottom end of the connecting rod mechanism, the top end of the connecting rod mechanism is connected to the hanging basket frame 104, and the top end of the connecting rod mechanism passes through the intersection of the rotation center lines of the first rotating axis 110 and the second rotating axis 111, so that the connecting rod mechanism can smoothly drive the hanging basket frame 104 to rotate around the first rotating axis 110 and / or the second rotating axis.

[0045] Further, if Figure 4 As shown, the connecting rod mechanism includes an oscillation shaft 106 and a connecting rod 107 hinged to the bottom end of the oscillation shaft 106, and a second magnetic member is provided at the bottom end of the connecting rod 107. The connecting rod mechanism has a simple structure and is easy to process. Specifically, on the hanging basket assembly, the oscillation shaft 106 is located at the center of the hanging basket 103, and a number of centrifuge tubes 105 are arranged circumferentially. One end of the connecting rod 107 is hinged to the oscillation shaft 106, and the other end is covered with a rollable ball 108. In other embodiments, the connecting rod mechanism can also be a three-link structure formed by hinged three connecting rods, as long as it can drive the hanging basket assembly.

[0046] Furthermore, the movement direction of the first magnetic element is perpendicular to the rotation centerline of the centrifugal drive assembly and forms an angle with the rotation centerline of the first rotation axis 110 and the rotation centerline of the second rotation axis 111. In this case, the hanging basket 104 rotates in two directions around the first rotation axis 110 and the second rotation axis 111 during shaking. Driven by these two axes, the hanging basket 104 can cause the liquid in the centrifuge tube 105 to generate a vortex motion, which can more fully mix and ensure sufficient shaking and oscillation.

[0047] Specifically, the extension direction of the linear guide rail 206 (corresponding to the movement direction of the first magnetic member) is the same as Figure 4 The vertical reference plane of the hanging basket frame 104 passing through the center line of the second rotating shaft 111 is at a certain angle, such as 10 to 30 degrees. Driven by the slider 205 and the linear guide rail 206, the first magnetic element cuts into the nutation space of the oscillation shaft 106 at a certain angle.

[0048] Of course, in other embodiments, the shaking drive assembly can also drive the hanging basket frame 104 to rotate perpendicular to the second rotation axis 111 to shake.

[0049] Furthermore, the second magnetic component and the first magnetic component are arranged in sequence along the direction close to the center line of the centrifugal drive assembly, so that the direction of the centrifugal movement of the second magnetic component (away from the centrifugal drive assembly) is opposite to the direction when it is connected to the first magnetic component (close to the centrifugal drive assembly), which can avoid the first magnetic component interfering with the centrifugal movement of the hanging basket assembly 109.

[0050] The centrifuge shaking mechanism in this embodiment works as follows:

[0051] 1. Centrifugal mode:

[0052] Start centrifugation:

[0053] The electromagnet 207 is powered off, the ball 108 is separated from the electromagnet 207, and the connecting rod 107 is under the action of gravity. Figure 5 As shown, it naturally droops to a vertical state in the plane XOZ. After starting the centrifugal motor 101, the centrifugal motor 101 drives the rotor 102 to rotate. Due to the centrifugal force, the hanging basket assembly 109 rotates as shown. Figure 2 The first rotation axis 110 in the YOZ plane rotates so that the hanging basket frame 104 and the hanging basket 103 are converted to a horizontal state from a vertical state. When the hanging basket frame 104 and the hanging basket frame are completely in a horizontal state, the centrifugal effect is best.

[0054] End of centrifugation:

[0055] As the centrifugal motor 101 gradually decelerates to 0, the basket frame 104 and the basket 103 gradually transform from a horizontal state to a vertical state. In fact, due to the friction between the basket 103, the first rotating shaft 110 and the rotor 102, the basket frame 104 and the basket 103 will not completely return to the vertical state, but will have a slight tilt relative to the vertical direction, and the bottom ends of the basket frame 104 and the basket 103 are further away from the rotation center line of the centrifugal drive assembly than the top ends. However, it should be noted that since the magnetic attraction of the electromagnet 207 can work within a certain range, if the electromagnet 207 is energized at this time, it can generate a magnetic attraction to the ball 108 in this state, and drive the connecting rod 107 to swing, so that the ball 108 and the electromagnet 207 are smoothly attracted and connected.

[0056] 2. Shake mode:

[0057] The centrifugal motor 101 is locked, and the rotor 102 no longer rotates. Then, the electromagnet 207 is energized, connecting it to the ball bearing 108. The shake motor 203 is activated. The rotation of the shake motor 203, via the eccentric disk 202, drives the mounting plate 204 and slider 205 to reciprocate along the linear guide 206. Simultaneously, the cam follower 201 moves within the linear slot 2041 of the mounting plate 204, pushing the mounting plate 204, which in turn drives the electromagnet 207 to reciprocate.

[0058] like Figures 2 to 5 As shown, the rotation center line of the first rotation axis 110 is the OY axis direction, and the rotation center line of the second rotation axis 111 is the OX axis direction. Since the linear guide 206 and the XOZ plane form a certain angle, as shown in FIG. Figure 7 As shown, the thrust exerted on the mounting plate 204 also has an angle with the OY axis, and the angle range can be 10 to 30 degrees, and 20 degrees is taken in this case. The hinge axis between the connecting rod 107 and the oscillation axis 106 is parallel to the OY axis, and the connecting rod 107 can only swing in the plane XOZ. Under the push of the mounting plate 204, while the connecting rod 107 swings in the plane XOZ, the connecting rod translates along the positive direction of the OY axis. Therefore, when the rotor 102 is fixed, the hanging basket 104 has two directions of movement, namely, rotation in the plane XOZ around the first rotation axis 110 and rotation in the plane YOZ around the second rotation axis 111. In particular, during the swinging process of the hanging basket 104, the hinge point of the oscillation axis 106 and the connecting rod 107 has a height change on the OZ axis. When the hinge point moves toward the positive direction of the OZ axis, the connecting rod 107 rotates relative to the oscillation axis 106 until the hinge point reaches the highest point when the two are collinear; when the hinge point moves toward the negative direction of the OZ axis, the connecting rod 107 rotates in the opposite direction relative to the oscillation axis 106, and the angle formed by the two gradually decreases.

[0059] The centrifuge shaking mechanism in this embodiment has the following advantages: when the ball 108 is separated from the electromagnet 207, the rotor 102 drives the hanging basket frame 104 to move, so as to realize centrifugal motion; the linear reciprocating motion of the electromagnet 207 driven by the eccentric motion, and the magnetic adsorption effect of the ball 108 and the electromagnet 207 can jointly simulate the manual shaking action, so that the centrifuge tube 105 can complete the two actions of centrifugation and shaking without transferring the centrifuge tube 105; the two actions of centrifugation and shaking can be connected in series by only turning on / off the electromagnet 207, and the centrifugation and shaking can be separated from each other and easily combined, and the equipment structure is compact; the mounting plate 204 of the first magnetic attraction member cuts into the nutation space of the oscillation shaft 106 at a certain angle, so that the oscillation shaft 106 can swing in two directions. Driven by the two axes of the hanging basket frame 104, the liquid in the centrifuge tube 105 will generate vortex motion, and the mixing is more sufficient.
