Description

Technical Field

[0001] This invention relates to the technical field of centrifuge equipment, and more specifically, to a vibrating centrifuge device. Background Technology

[0002] Currently in the medical field, blood is typically separated using centrifuges after collection for convenient subsequent testing. The high-speed rotation of the centrifuge rotor generates strong centrifugal force, accelerating the sedimentation rate of particles in the liquid being tested, thus separating substances with different buoyant densities and sedimentation coefficients. In related technologies, a vacuum centrifuge includes a body, a rotor rotatably connected within the centrifuge body, and a motor that drives the rotor. A cover is hinged to the centrifuge; opening the cover allows the liquid to be tested to be placed onto the rotor, and starting the motor causes the rotor to rotate, achieving separation.

[0003] However, during centrifugation, it is sometimes necessary to shake and stir the sample in the test tube midway to ensure thorough mixing. This requires operators to frequently transfer the test tube between the centrifuge and the shaker, which not only affects the preparation efficiency but also easily causes contamination and affects subsequent testing. Summary of the Invention

[0004] The problem solved by this invention is to provide a shaking centrifuge device that can simultaneously perform centrifugation and shaking operations on samples.

[0005] To address the aforementioned problems, this invention provides a vibrating centrifuge device, comprising a main frame and a main power source for driving the main frame to rotate, as well as a vibrating assembly and a sliding assembly. The main frame has a plurality of sub-frames arranged circumferentially, each sub-frame having a support portion for fixing samples. Each sub-frame has a transmission rod. The vibrating assembly includes an eccentric sleeve and a vibrating power source. The sliding assembly drives the vibrating assembly to move toward the transmission rod so that the eccentric sleeve is inserted into the transmission rod. The vibrating power source drives the eccentric sleeve to rotate.

[0006] The advantages of the above scheme are as follows: The main frame is driven by an active power source, allowing the sample on the sub-frame to rotate and achieve centrifugation. Simultaneously, due to the inclusion of the oscillation and sliding components, after temporary centrifugation, the eccentric sleeve moves towards the transmission rod under the drive of the sliding component until the transmission rod inserts into the eccentric sleeve. The oscillation power source then drives the eccentric sleeve to rotate, causing the sample on the sub-frame to oscillate and mix. After oscillation, the sliding component resets the eccentric sleeve, allowing the sample to continue centrifugation as needed. Compared to existing technologies, this scheme achieves centrifugation and oscillation simultaneously without sample transfer, resulting in high preparation efficiency and no contamination.

[0007] Preferably, the sub-frame includes an outer ring frame and an inner ring frame. The outer ring frame is rotatably connected to the main frame and its rotation axis is perpendicular to the radial direction of the main frame. The inner ring frame is rotatably connected to the inner side of the outer ring frame and its rotation axis is parallel to the radial direction of the main frame. The resting part is located on the middle of the inner ring frame. Thus, the sample can rotate in two rotational directions as the rotation speed of the main frame changes, thereby obtaining a better centrifugation effect.

[0008] Preferably, the rotation axis of the eccentric sleeve is parallel to the rotation axis of the main frame, so that the vibration direction of the sub-frame matches the rotation direction of the main frame, thereby reducing the vibration impact of the sub-frame on the main frame.

[0009] Preferably, the transmission rod is connected to the middle of the inner ring frame, and the transmission rod is arranged in a direction parallel to the rotation axis of the eccentric sleeve, so that the eccentric sleeve can more effectively drive the sub-frame to vibrate.

[0010] Preferably, the transmission rod has a raised truncated cone at one end facing the eccentric sleeve. The truncated cone is used to cooperate with the eccentric sleeve, so that the eccentric sleeve and the transmission rod can be tightly connected, ensuring that the subframe can achieve a better vibration effect.

[0011] Preferably, the outer periphery of the main frame is provided with a number of circumferentially arranged grooves, and the two sides of the outer ring frame are provided with pins that are rotatably connected to the groove walls of the grooves, so that the sub-frame is more stably connected to the main frame.

[0012] Preferably, the outer periphery of the main frame is provided with several circumferentially arranged grooves for accommodating the outer ring frame. The groove walls are provided with guide rails arranged radially along the main frame. A rotating shaft arranged radially perpendicular to the main frame is slidably connected to the guide rails. A spring arranged radially on the main frame is provided, which pushes the rotating shaft to slide radially along the main frame. The outer ring frame is rotatably connected to the rotating shaft in the groove. The spring further reduces the impact of the sub-frame's vibration on the main frame, and during centrifugal operation, the sub-frame can rotate more stably under the influence of the main frame.

Detailed Implementation

[0019] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. 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. It should also be noted that all directional indications (such as up, down, left, right, front, back, inside, outside) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0020] Please see Figures 1-3 An embodiment of the present invention provides a vibrating centrifuge device, including a main frame 1 and a main power source 1.1 for driving the main frame 1 to rotate, and also includes a vibrating assembly 3 and a sliding assembly 4. The main frame 1 is provided with a plurality of sub-frames 2 arranged circumferentially, and each sub-frame 2 is provided with a support for fixing samples. Each sub-frame 2 is provided with a transmission rod 2.3. The vibrating assembly 3 includes an eccentric sleeve 3.1 and a vibrating power source 3.2. The sliding assembly 4 is used to drive the vibrating assembly 3 to move toward the transmission rod 2.3 so that the eccentric sleeve 3.1 is inserted into the transmission rod 2.3. The vibrating power source 3.2 is used to drive the eccentric sleeve 3.1 to rotate.

[0021] The above scheme uses a main power source 1.1 to drive the main frame 1, enabling the sample on the sub-frame 2 to rotate and achieve centrifugation. Simultaneously, due to the inclusion of the oscillation component 3 and the sliding component 4, after the sample centrifugation is temporarily completed, the eccentric sleeve 3.1 moves towards the transmission rod 2.3 under the drive of the sliding component 4 until the transmission rod 2.3 inserts into the eccentric sleeve 3.1. Then, the oscillation power source 3.2 drives the eccentric sleeve 3.1 to rotate, causing the sample on the sub-frame 2 to oscillate and mix. After oscillation is complete, the sliding component 4 moves the eccentric sleeve 3.1 back to its original position, allowing the sample to continue centrifuging as needed. Compared to existing technologies, this scheme achieves centrifugation and oscillation simultaneously without sample transfer, resulting in high preparation efficiency and no contamination.

[0022] In this embodiment, the sliding component 4 is preferably an electric push rod, or it can be a cylinder or other power component that can drive the oscillation component 3 to move back and forth; the main power source 1.1 and the oscillation power source 3.2 are both preferably motors.

[0023] Preferably, the sub-frame 2 includes an outer ring frame 2.1 and an inner ring frame 2.2. The outer ring frame 2.1 is rotatably connected to the main frame 1 and its rotation axis is perpendicular to the radial direction of the main frame 1. The inner ring frame 2.2 is rotatably connected to the inner side of the outer ring frame 2.1 and its rotation axis is parallel to the radial direction of the main frame 1. The resting part is located on the middle part of the inner ring frame 2.2. Thus, the sample can rotate in two rotational directions as the main frame 1 rotates, thereby obtaining a better centrifugation effect.

[0024] In this embodiment, the rotation axis of the eccentric sleeve 3.1 is parallel to the rotation axis of the main frame 1, and both rotation axes are vertical, so that the vibration direction of the sub-frame 2 matches the rotation direction of the main frame 1, thereby reducing the vibration influence of the sub-frame 2 on the main frame 1.

[0025] The transmission rod 2.3 is preferably arranged vertically, so that the eccentric sleeve 3.1 can more effectively drive the sub-frame 2 to vibrate. The upper end of the transmission rod 2.3 is connected to the middle of the inner ring frame 2.2, and the lower end of the transmission rod 2.3 is provided with a protruding frustum 2.4, which is used to cooperate with the eccentric sleeve 3.1, so that the eccentric sleeve 3.1 and the transmission rod 2.3 can be tightly connected, ensuring that the sub-frame 2 can achieve a better vibration effect.

[0026] In this embodiment, the outer periphery of the main frame 1 is provided with four circumferentially arranged grooves 1.2, each groove 1.2 corresponding to a sub-frame 2. The outer ring frame 2.1 is provided with pins 2.1a on both sides, which are rotatably connected to the groove walls of the grooves 1.2, thereby making the sub-frame 2 more stably connected to the main frame 1.

[0027] like Figure 4As shown, in another embodiment, the outer periphery of the main frame 1 is provided with four circumferentially arranged grooves 1.2 for accommodating the outer ring frame 2.1. The groove walls of the grooves 1.2 are provided with guide rails 1.3 arranged radially along the main frame 1. A rotating shaft 2.1b arranged radially perpendicular to the main frame 1 is slidably connected to the guide rails 1.3. A spring 1.4 is provided on the main frame 1 arranged radially. The spring 1.4 is used to push the rotating shaft 2.1b to slide radially along the main frame 1. The outer ring frame 2.1 is rotatably connected to the rotating shaft 2.1b of the grooves 1.2. The setting of the spring 1.4 further reduces the impact of the oscillation of the sub-frame 2 on the main frame 1, and the spring 1.4 can play a buffering role during centrifugal operation, so that the sub-frame 2 can rotate more stably under the drive of the main frame 1.

[0028] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art will recognize that various changes and modifications can be made without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
