Description

TECHNICAL FIELD

[0001] The utility model relates to the field related to oscillator, concretely is a vortex oscillator. BACKGROUND

[0002] In natural science experiments, it is often necessary to mix various reagents, solutions or chemical substances for processing to ensure uniformity of reactants, thereby improving reaction efficiency and product quality. This requirement is particularly prominent in fields such as chemical analysis, life sciences, environmental monitoring, and material preparation. In particular, in a laboratory environment, the oscillation mixing of reagent centrifuge tubes is a common and important operation. Traditional mixing methods often rely on manual oscillation or the use of simple mechanical mixers, such as a shaking bed, a roller mixer, etc. Manual oscillation is not only time-consuming and labor-intensive, but also unstable in mixing effect. While traditional mechanical mixers achieve a certain degree of automation, their mixing force is weak. To overcome these shortcomings, vortex oscillators have emerged.

[0003] A vortex oscillator is a device that uses electromagnetic induction and mechanical motion principles to mix samples through rotational motion or vortex oscillation. It uses magnetic force to drive shaft movement, causing the sample in the sample container (such as a centrifuge tube) to rotate and mix, thereby breaking the laminar flow in the sample and promoting uniform mixing of the sample. In addition, the vortex oscillator can also drive the shaking bed below to move up and down constantly, generating shear force and flexural stress inside the liquid, forming a vortex, and further improving the mixing effect. For example, the Chinese authorized patent with publication number CN213966304U (biochemical detection vortex oscillator), the Chinese authorized patent with publication number CN212017607U (automatic vortex oscillator tray), the Chinese authorized patent with publication number CN205948779U (multi-tube vortex oscillator), etc.

[0004] The above-mentioned prior art mixes samples by generating rotational motion or vortex oscillation, but during vortex oscillation, the vortex oscillator switch and the timer switch need to be pressed, and after the timer displays the target oscillation time, the vortex oscillator switch needs to be turned off to ensure that the oscillation time meets the oscillation requirements. This requires constant attention to the timer, and after the oscillation is completed, the centrifuge tube needs to be taken out, the vortex oscillator switch needs to be turned off, and the timer switch needs to be turned off, which is relatively cumbersome in operation.

[0028] As shown in Figure 4 and Figure 5 , the second pressing part 15 is formed with first gear part 16 away from the first pressing part 14 side, the rear bottom plate 5 front end side is connected with intermediate transition drive piece 17 through bearing vertical plate along the trigger switch piece 12 side. The intermediate transition drive piece 17 is formed with second gear part 18 on one side, and the second gear part 18 is engaged with the first gear part 16. When the trigger switch piece 12 rotates, it will drive the intermediate transition drive piece 17 to rotate synchronously.
