Description

A multifunctional adjustable mixer Technical Field

[0001] This utility model relates to the field of mixing instruments, and in particular to a multifunctional adjustable mixing instrument. Background Technology

[0002] A homogenizer is a commonly used experimental device for mixing sample mixtures by shaking. It replaces manual shaking, is convenient to use, and is widely used in environmental monitoring, medical and health, petrochemical, food, and metallurgical fields. In laboratories of these fields, various experimental samples in centrifuge tubes are typically mixed thoroughly. After adding the mixed sample to the centrifuge tube, the homogenizer shakes the sample for a certain period to obtain a relatively homogeneous solution. It offers advantages such as fast mixing speed and thorough mixing. There are many types of homogenizers, such as rotary mixers, vertical mixers, rocking mixers, and vortex mixers. In biochemical laboratories, during reaction tests or experiments on cells, blood samples, etc., the sampled or prepared liquid sample is usually placed inside a test tube or centrifuge tube, and then homogenized using a homogenizer. Depending on the sample, different homogenizers may be required for the experiment.

[0003] However, using multiple mixers is cumbersome and expensive. Existing mixers can generally only meet the mixing needs of one type of centrifuge tube and cannot mix multiple centrifuge tubes of different sizes at the same time, resulting in low mixing efficiency. Moreover, mixers only have a single mixing function during use and do not have multiple different mixing modes. They also cannot adjust the tilt angle and mixing direction of the centrifuge tubes during mixing, nor can they mix centrifuge tubes of different temperatures at the same time. This results in the need for multiple mixing operations when there are many centrifuge tubes to be mixed, which reduces the mixing efficiency of the mixer. Summary of the Invention

[0004] To address the technical problems of existing mixers being unable to simultaneously mix centrifuge tubes of various sizes, and having limited mixing modes and functions, thus reducing the mixing efficiency of centrifuge tubes, this utility model provides the following technical solution.

[0005] This utility model discloses a multifunctional adjustable mixer, comprising a base with a control panel and a rotating column. A turntable is fixedly connected to the upper end of the rotating column. A bracket with a first support plate and a second support plate respectively on both sides is fixedly connected to the upper part of the turntable. A main shaft with several fixed sleeves is rotatably connected between the upper ends of the first support plate and the second support plate. A drive motor connected to one end of the main shaft is fixedly connected to one side of the first support plate. Fixed columns are fixed at both ends of the fixed sleeves. A quick-release connecting cylinder is detachably connected to the fixed column. A tube rack with a heating wire in the inner cavity for inserting centrifuge tubes is fixedly connected to the quick-release connecting cylinder.

[0006] As a further technical solution, the outer wall of the fixed column is provided with a plurality of positioning holes in the radial direction, the quick-release connecting sleeve is sleeved on the outer wall of the fixed column and the quick-release connecting sleeve is provided with an adjustment hole that matches the positioning holes, and a wing bolt is connected between the positioning holes and the adjustment holes.

[0007] As a further technical solution, the main shaft has a hollow structure and is connected to the wire hole axially arranged in the fixed column, and the wire hole is connected to the heating wire in the tube frame.

[0008] As a further technical solution, the tube rack is provided with a number of tube holes for placing centrifuge tubes, and the inner wall of the tube holes is provided with a number of elastic protrusions that clamp the centrifuge tubes.

[0009] As a further technical solution, an extension cylinder is fixedly provided at the lower end of the tube hole, and the elastic protrusion extends to the inner wall of the extension cylinder.

[0010] As a further technical solution, the tube rack is made of a thermally conductive material.

[0011] The beneficial effects of this utility model are as follows: A turntable is connected to the upper part of the base, and a support is fixedly connected to the upper part of the turntable. The support can connect multiple tube racks of different specifications via a main shaft, thus allowing simultaneous mixing of centrifuge tubes of various specifications, improving mixing efficiency. The turntable and main shaft can drive the tube racks to rotate and mix at multiple angles horizontally and vertically. Each tube rack is fixedly connected to a quick-release connecting cylinder, whose tilt angle and mixing direction relative to the fixed column can be adjusted. Heating wires are installed inside the tube racks to adjust the mixing temperature and allow for adjustment of multiple mixing modes according to the mixing requirements of the centrifuge tubes. This reduces the impact of a single mixer being unable to meet the needs of various centrifuge tube specifications in laboratory work, shortens unnecessary time waste, and improves mixing efficiency.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0019] As shown in Figures 1 and 2, this utility model discloses a multifunctional adjustable mixer, including a base 1 with a control panel 101 and a rotating column 102. A turntable 2 is fixedly connected to the upper end of the rotating column 102. The control panel 101 is equipped with buttons for adjusting the mixing temperature, mixing speed, and time. The base 1 adopts the structure of an existing mixer, and contains a controller and a motor for driving the turntable 2 to rotate for mixing, etc., which will not be described in detail here.

[0020] As shown in Figures 1 and 3, in a preferred embodiment, a bracket 3 is fixedly connected to the upper part of the turntable 2, with a first support plate 301 and a second support plate 302 respectively on both sides. The bracket 3 is an inverted U-shaped structure and is fixedly connected to the turntable 2 by bolts or welding. The bracket 3 can rotate horizontally with the turntable 2. A main shaft 4 is rotatably connected between the upper ends of the first support plate 301 and the second support plate 302. A drive motor 5 is fixedly connected to one end of the main shaft 4 on one side of the first support plate 301, and the drive motor 5 drives the main shaft 4 to rotate.

[0021] The main shaft 4 is axially equipped with several fixed sleeves 401, each fixed sleeve 401 being perpendicular to the main shaft 4, and each fixed sleeve 401 having a fixed post 402 fixed at both ends. A quick-release connecting cylinder 6 is detachably connected to the end of the fixed post 402 away from the fixed sleeve 401. The quick-release connecting cylinder 6 is fixedly connected to a tube rack 8 for loading centrifuge tubes. The quick-release connecting cylinder 6 is radially tiltable and rotatable relative to the fixed post 402, allowing the tilt angle and mixing direction of the quick-release connecting cylinder 6 relative to the fixed post 402 to be adjusted. Therefore, the centrifuge tubes on the tube rack 8 can be mixed in multiple tilting directions, both horizontally and longitudinally, under the action of the turntable 2, the main shaft 4, and the fixed post 402, improving mixing efficiency and adaptability.

[0022] In a preferred embodiment, the outer wall of the fixed column 402 is provided with a plurality of positioning holes 403 radially. The quick-release connecting cylinder 6 is sleeved on the outer wall of the fixed column 402, and the quick-release connecting cylinder 6 is provided with an adjustment hole 601 that matches the positioning hole 403. Both the adjustment hole 601 and the positioning hole 403 are screw holes, and a wing bolt 7 is connected between the positioning hole 403 and the adjustment hole 601. In this embodiment, there is one positioning hole 403 and multiple adjustment holes 601. Of course, there can also be multiple positioning holes 403 and one adjustment hole 601. This utility model does not make any particular limitation. Holding the tube rack 8, the quick-release connecting cylinder 6 is rotated relative to the fixed column 402. After adjusting the tilt angle of the tube rack 8, the adjustment hole 601 is aligned with the positioning hole 403. Then, the wing bolt 7 is screwed into the adjustment hole 601 and the positioning hole 403 by hand. This simple operation can keep the tube rack 8 stably connected to the main shaft 4, ensuring the stability of the tube rack 8 and the centrifuge tube during the mixing process.

[0023] The figure shows four pipe supports 8. The size of the pipe holes 801 of each pipe support 8 is different. Of course, the size of the four pipe supports 8 can be the same or different. Similarly, the number of pipe supports 8 can be more than four or less than four. This utility model does not make any special limitation on it.

[0024] In a preferred embodiment, the main shaft 4 is hollow. A conductive slip ring is provided inside both the rotating column 102 and the main shaft 4. Wires from the base 1 can pass through the rotating column 102 and the main shaft 4 into the fixed column 402. The fixed column 402 has an axially oriented wire hole 404 for the wires to pass through. The quick-release connecting cylinder 6 has a through hole, and the inner cavity of the tube frame 8 has a heating wire. Wires passing through the wire hole 404 have quick-release connectors, and the heating wire inside the tube frame 8 also has a quick-release connector, facilitating the connection of the wires in the wire hole 404 to the heating wire inside the tube frame 8. The tube frame 8 is made of a thermally conductive material. When the heating wire inside the tube frame 8 is energized, the entire tube frame 8 conducts heat, causing a temperature change in the centrifuge tubes placed inside. This allows for setting the mixing temperature of the centrifuge tubes, improving the mixing effect of the mixer.

[0025] As shown in Figure 4, in a preferred embodiment, the tube rack 8 has several tube holes 801 for placing centrifuge tubes. The tube holes 801 are used to insert centrifuge tubes. The inner wall of the tube holes 801 is axially provided with several elastic protrusions 802 for clamping the centrifuge tubes. An extension cylinder 803 is fixedly provided at the lower end of the tube holes 801, and the elastic protrusions 802 extend to the inner wall of the extension cylinder 803. Thus, the extension cylinder 803 extending axially from the tube holes 801 can further increase the clamping force and contact area of ​​the centrifuge tubes, ensuring the stability of the centrifuge tubes during the mixing process. At the same time, the increase in axial contact area also ensures the stability of the centrifuge tube temperature when the tube rack 8 is heated.

[0026] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
