Description

Technical Field

[0001] This utility model relates to the field of biotechnology, and in particular to a mixing device. Background Technology

[0002] In the fields of biochemical experiments and clinical testing, the homogenizer is a key sample pretreatment device, and its performance parameters directly affect the reliability of experimental results such as cell culture, nucleic acid extraction, and immunoassay.

[0003] However, traditional mixing mechanisms employ a two-dimensional planar rotation mode, with the rotation axis tilt angle fixed within the range of 15°±3°. This rigid motion trajectory is difficult to meet the differentiated requirements of different experimental systems for mixing dynamics, such as: conventional mixing requires horizontal rotation, cell resuspension requires vertical oscillation, viscous liquid mixing requires spiral tumbling, and anti-precipitation requires wave oscillation. Utility Model Content

[0004] The purpose of this invention is to provide a mixer that solves the aforementioned problems in the prior art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A mixer includes a centrifuge disc, a first motor, a second motor, a horizontal plate, a base, a compression spring, and an electromagnetic module. A first motor with its output shaft facing upwards is fixedly mounted under the centrifuge disc. The housing of the first motor is fixedly mounted on a rotating ring. Second motors are mounted at both ends of the rotating ring. The housings of the second motors are fixed to the horizontal plate via uprights. A base is spaced apart under the horizontal plate. A compression spring and an electromagnetic module are respectively positioned between the center of the base and the bottom of the horizontal plate, and between the sides of the base and the bottom of the horizontal plate. The electromagnetic module includes a permanent magnet mounted at the bottom of the horizontal plate and an electromagnet mounted on the base. The permanent magnet and the electromagnet attract each other with opposite poles. The first motor, the second motor, and the electromagnetic module are all electrically connected to an external controller.

[0007] The beneficial effects of this invention are: this mixer combines the above four mixing dynamics, which can meet the different requirements of mixing dynamics for four experimental systems: conventional mixing, cell resuspension, viscous liquid mixing, and anti-precipitation.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the centrifugal disc includes an upper disc, a middle disc, and a lower disc stacked sequentially from top to bottom. One end of the upper disc, the middle disc, and the lower disc are horizontally connected by a multi-stage rotating rod, and the other end of the upper disc, the middle disc, and the lower disc are fixedly connected by a through rod.

[0010] The further beneficial effects of adopting the above are: by setting up an upper plate, a middle plate, and a lower plate, and rotating them through a multi-stage rotating rod and fixing them with a rod, the capacity of the centrifuge plate to hold centrifuge tubes can be increased, and a large number of centrifuge tubes can be processed at the same time.

[0011] Furthermore, the upper plate, middle plate, and lower plate are respectively provided with a first insertion hole, a second insertion hole, and a third insertion hole with progressively smaller diameters, and each of the first insertion hole, the second insertion hole, and the third insertion hole is provided with a silicone retaining ring.

[0012] The further beneficial effects of adopting the above are: a 50ml centrifuge tube can be placed in the first socket, a 15ml centrifuge tube can be placed in the second socket, and a 5ml centrifuge tube can be placed in the third socket; the silicone retaining ring can prevent the centrifuge tube from falling out of the socket; it can process 50ml / 15ml / 5ml centrifuge tubes simultaneously or separately, increasing the mixing efficiency and making it highly practical.

[0018] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0019] Example 1

[0020] like Figure 1 and Figure 2As shown, a mixer includes a centrifuge disc 1, a first motor 2, a second motor 3, a horizontal plate 4, a base 6, a compression spring 5, and an electromagnetic module 7. The first motor 2 with its output shaft facing upward is fixedly installed under the centrifuge disc 1. The housing of the first motor 2 is fixedly installed on a rotating ring 32. The second motor 3 is installed at both ends of the rotating ring 32. The housing of the second motor 3 is fixed to the horizontal plate 4 by a vertical rod 31. The base 6 is installed at intervals under the horizontal plate 4. The compression spring 5 and the electromagnetic module 7 are respectively installed between the middle of the base 6 and the bottom of the horizontal plate 4, and between the two sides of the base 6 and the bottom of the horizontal plate 4. The electromagnetic module 7 includes a permanent magnet 71 installed at the bottom of the horizontal plate 4 and an electromagnet 72 installed on the base 6. The permanent magnet 71 and the electromagnet 72 attract each other with opposite poles. The first motor 2, the second motor 3, and the electromagnetic module 7 are all electrically connected to an external controller.

[0021] Place the centrifuge tubes on centrifuge plate 1, start the first motor 2 to rotate centrifuge plate 1 horizontally, and complete the routine mixing operation. Place the centrifuge tubes on centrifuge plate 1, and simultaneously start and stop the electromagnets 72 on both sides of the horizontal plate 4. Under the attraction of the electromagnets 72 and the permanent magnet 71 and the elastic force of the compression spring 5, centrifuge plate 1 oscillates up and down, and completes the cell resuspension operation. Place the centrifuge tubes on centrifuge plate 1, and simultaneously start the first motor 2 and the second motor 3. While the first motor 2 rotates centrifuge plate 1 horizontally, the second motor 3 rotates the combination of the first motor 2 and centrifuge plate 1 vertically, causing centrifuge plate 1 to tumble in a spiral, and completes the mixing operation of viscous liquid. Centrifuge tubes are placed on centrifuge tray 1. The electromagnets 72 on both sides of the horizontal plate 4 are differentially activated. When one electromagnet 72 is activated, the horizontal plate moves the centrifuge tray 1 to one side under the magnetic attraction. When the electromagnet 72 is deactivated and the other electromagnet 72 is activated, the horizontal plate moves the centrifuge tray 1 to the other side under the magnetic attraction. The horizontal plate moves in a wave-like motion under the action of the electromagnets 72 on both sides and the compression spring 5, thus completing the anti-precipitation operation of the centrifuge tubes. This mixer has the above four mixing kinetics and can meet the different mixing kinetics requirements of four experimental systems: conventional mixing, cell resuspension, viscous liquid mixing, and anti-precipitation.

[0022] Example 2

[0023] like Figure 1 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0024] The centrifuge tray 1 includes an upper tray 11, a middle tray 12, and a lower tray 13 stacked sequentially from top to bottom. One end of the upper tray 11, the middle tray 12, and the lower tray 13 are horizontally rotatably connected by a multi-stage rotating rod 14, and the other end of the upper tray 11, the middle tray 12, and the lower tray 13 are fixedly connected by a through-hole rod 15. By setting up the upper tray 11, the middle tray 12, and the lower tray 13 and rotating them through the multi-stage rotating rod 14 while fixing them with the through-hole rod 15, the capacity of the centrifuge tray 1 for holding centrifuge tubes can be increased, allowing for the simultaneous processing of a large number of centrifuge tubes.

[0025] The upper plate 11, middle plate 12, and lower plate 13 are respectively provided with a first insertion hole 111, a second insertion hole 121, and a third insertion hole 131 with progressively decreasing diameters. Each insertion hole 111, 121, and 131 is fitted with a silicone retaining ring. A 50ml centrifuge tube can be placed in the first insertion hole 111, a 15ml centrifuge tube in the second insertion hole 121, and a 5ml centrifuge tube in the third insertion hole 131. The silicone retaining rings prevent the centrifuge tubes from falling out of the insertion holes. This design allows for the simultaneous or individual processing of 50ml / 15ml / 5ml centrifuge tubes, increasing mixing efficiency and enhancing practicality.

[0026] Example 3

[0027] like Figure 3 As shown, this embodiment is a further improvement on any one of embodiments 1 to 2, as detailed below:

[0028] It also includes a light shield 9, with a locking ring 91 on the opening of the light shield 9 engaging with a corresponding annular slot 41 on the horizontal plate 4. The light shield 9 prevents the degradation of photosensitive reagents inside the centrifuge tubes during the operation of the mixer.

[0029] A hot and cold air fan 8 is installed on the horizontal plate 4 inside the light shield 9. It is used to maintain the temperature of the solution inside the centrifuge tube and prevent excessive temperature difference from causing enzymes and volatile substances to become inactive.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
