[0030] In the description of the utility model, unless otherwise explicitly limited, the words such as setting, installation, connection should be broadly understood, and the specific meaning of the above words in the utility model can be reasonably determined by the person skilled in the art in combination with the specific content of the technical scheme.

[0031] Reference Figure 1 According to the mixing instrument of the utility model embodiment, including base 100, clamping piece 200 and rotation driving device 300.

[0032] Clamping piece 200 is arranged on base 100, and clamping piece 200 is used for clamping test tube, so that the axis of test tube on clamping piece 200 forms an angle with the up-down direction. The output end of rotation driving device 300 is in transmission connection with clamping piece 200, and rotation driving device 300 is used to drive clamping piece 200 to rotate, so that the test tube on clamping piece 200 rotates around its own shaft.

[0033] It needs to be explained that in the prior art, after clamping piece 200 in mixing instrument clamps test tube, the test tube remains in vertical state, that is, the axis of test tube is parallel to the up-down direction, so that the test tube is always in vertical state in the process of rotating and mixing. In the process of rotation, the sample near the test tube wall has a faster flow rate under the action of centrifugal force, and the sample near the axis of test tube has a slower flow rate, so that there is a large difference in the flow rate of sample at the test tube wall and the axis, and then the middle part of the sample in the test tube is easy to form concentrated large vortex. The concentrated large vortex is concentrated vortex. After the formation of concentrated large vortex, the sample mainly does circular motion around the axis of test tube, and in this case, the exchange between different components in the sample becomes slow, and different levels of components in the sample are difficult to effectively mix, and then the mixing effect of the mixing instrument is reduced.

[0034] Clamping piece 200 can clamp test tube, and under the clamping action of clamping piece 200, the axis of test tube forms an angle with the up-down direction. The output end of rotation driving device 300 is in transmission connection with clamping piece 200, so that rotation driving device 300 can drive clamping piece 200 to rotate, and then the test tube on clamping piece 200 rotates around its own shaft. In the utility model embodiment, the axis of test tube forms an angle with the up-down direction, which means that the test tube is in an inclined state.

[0035] It can be understood that when the sample needs to be mixed, the experimenter can pour the sample to be mixed into the test tube and place the test tube on the clamping piece 200, so that the clamping piece 200 can clamp the test tube. Under the clamping action of the clamping piece 200, the axis of the test tube forms an angle with the up-down direction, that is, the test tube is in an inclined state. Then the experimenter starts the rotary drive device 300, and the rotary drive device 300 drives the clamping piece 200 and the test tube on the clamping piece 200 to rotate. In the process of rotation of the test tube, the test tube always maintains an inclined state under the action of the clamping piece 200. In the process of rotation of the test tube in the inclined state, the middle part of the sample in the test tube will not generate concentrated large eddies, and the flow path of the sample becomes more complex, not only making the exchange between different components in the sample faster, but also making the sample flow more in the up-down direction, so that the components at different levels in the sample can be mixed more effectively, thereby improving the mixing effect of the mixer.

[0036] It needs to be explained that in the process of rotation of the test tube in the inclined state, the sample in the test tube is simultaneously subjected to the action of gravity and centrifugal force. The combined action of gravity and centrifugal force makes the flow path of the sample complex, so that the components at different levels in the sample can be more easily exchanged with each other, that is, the components close to the bottom wall of the test tube can be more easily brought to the upper layer of the sample, thereby improving the mixing effect of the sample in the test tube. In the embodiment of the utility model, the inclination angle of the test tube refers to the angle formed by the axis of the test tube and the up-down direction.

[0037] Reference Figure 1 and Figure 2 The mixer further comprises a support 120, the clamping piece 200 and the rotary drive device 300 are arranged on the support 120, and the support 120 is connected to the base 100 in a rotatable manner, so that the clamping piece 200 can swing relative to the base 100, and the angle formed by the axis of the test tube on the clamping piece 200 and the up-down direction can be adjusted. In the embodiment of the utility model, the rotation axis of the support 120 is perpendicular to the up-down direction, that is, the rotation axis of the support 120 is perpendicular to the axis of the test tube on the clamping piece 200 and the clamping piece 200. It can be understood that when the experimenter needs to adjust the angle formed by the axis of the test tube and the up-down direction, that is, the experimenter needs to adjust the inclination angle of the test tube, the support 120 can be driven to rotate. Since the clamping piece 200 and the rotary drive device 300 are arranged on the support 120, the support 120 can drive the clamping piece 200 to swing relative to the base 100, so that the test tube can swing together with the clamping piece 200, so as to adjust the inclination angle of the test tube. Specifically, the base 100 is provided with a support column 140, and the support 120 is connected to the support column 140 in a rotatable manner.

[0038] It needs to be explained that, on the one hand, different samples have different physical properties such as density, viscosity, etc. The inclination angle of the test tube in the mixing instrument can be adjusted according to the specific characteristics of different samples. For example, when the sample is relatively thick, adjusting the inclination angle of the test tube can change the flow state of the sample in the test tube, improve the fluidity, and thus achieve better mixing effect, ensuring that different samples can have the most suitable mixing method. On the other hand, in some specific experiments, different experimental stages may require different mixing degrees or methods. For example, in the early stage of the experiment, a gentle mixing method may be required. At this time, the inclination angle of the test tube can be adjusted to be smaller. In the later stage of the experiment, a more thorough mixing method may be required. At this time, the inclination angle of the test tube can be adjusted to be larger. The mixing instrument allows the experimenter to flexibly adjust the inclination angle of the test tube according to the characteristics of different samples and different experimental stages, so as to find the most suitable mixing condition, thereby improving the use flexibility of the mixing instrument.

In the embodiment of the present application, the arc-shaped through hole 122 takes the axis of the hinge shaft 121 as the center line. The fastening assembly 130 comprises a bolt and a nut. The bolt is arranged in the arc-shaped through hole 122 of the support 120 and the mounting hole 150 of the base 100. The nut is threadedly connected with the bolt. When the inclination angle of the test tube needs to be adjusted, the experimenter can loosen the nut and rotate the support 120, so as to adjust the inclination angle of the test tube on the clamping piece 200. After the inclination angle of the test tube is adjusted, the experimenter can tighten the nut, so that the nut and the bolt clamp the base 100 and the support 120, and then the support 120 is fixed on the base 100, avoiding the rotation of the support 120 in the subsequent mixing process, and ensuring that the mixing process can be carried out smoothly. In the embodiment of the present application, the base 100 is provided with two mounting holes 150. The support 120 is provided with two arc-shaped through holes 122.
