Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chemical experimental instruments, and particularly relates to a vortex oscillator. Background Art
[0002] In chemical experiments, liquid extractants are often used to extract relevant analytes in solid powder samples. The traditional extraction step of solid-liquid sample solutions usually adopts a vertical oscillation method. Specifically, a centrifuge tube containing the solid powder sample and the liquid extractant is vertically inserted into the sample tray of the oscillator, and the solid-liquid sample solution in the centrifuge tube is oscillated and mixed using the eddy current principle, so that the solid-liquid sample solution in the centrifuge tube is fully mixed.
[0003] However, the traditional vertical oscillation method has an unsatisfactory extraction effect on solid-liquid sample solutions. Its limitations are specifically manifested as follows: during the vortex oscillation of the vertically placed centrifuge tube, the solid powder sample immersed in the liquid extractant will adhere to the bottom of the centrifuge tube, and the overall solid powder sample will form a relatively compact state, making it difficult for the solid powder sample to be fully dispersed during the vortex oscillation. This also makes it impossible for the liquid extractant to fully contact the solid powder sample, resulting in incomplete mixing of the liquid extractant and the solid powder sample. Finally, the extraction of the solid-liquid sample solution is insufficient, greatly affecting the subsequent detection and analysis results, and further affecting the judgment of product quality and safety indicators.

[0026] See Figure 1 , the present utility model provides a vortex oscillator for mixing the solid-liquid sample solution in a centrifuge tube, which includes a base 3, a driving mechanism, an adjusting component 4, and an oscillating component 1. The oscillating component 1 includes two parts, namely an upper oscillating disk 101 and a lower oscillating disk 102. Preferably, the length of the upper oscillating disk 101 is greater than the length of the lower oscillating disk 102. The left and right sides of the upper oscillating disk 101 are both connected to the base 3 through the adjusting component 4. The driving mechanism is installed on the base 3 and is connected to the lower oscillating disk 102. The driving mechanism can drive the lower oscillating disk 102 to perform circular motion in the vertical plane, so that the lower oscillating disk 102 drives the centrifuge tube to perform circular motion in the vertical plane. A placement groove 112 for horizontally placing the centrifuge tube is provided at the top of the lower oscillating disk 102, and an avoidance groove 111 for avoiding the centrifuge tube is provided at the bottom of the upper oscillating disk 101.

By providing a driving mechanism, the driving mechanism can provide power to drive the lower oscillation disk 102 to perform circular motion in a vertical plane, that is, the lower oscillation disk 102 drives the centrifuge tube to perform circular motion in a vertical plane, thereby vortex-oscillating the solid-liquid sample solution in the centrifuge tube, enabling the solid-liquid sample solution in the centrifuge tube to be fully mixed, improving the extraction effect, and ensuring the reliability and accuracy of subsequent detection results. By providing an avoidance groove 111 at the bottom of the upper oscillation disk 101, when the vortex oscillator is working, it can prevent the centrifuge tube from colliding with the upper oscillation disk 101 when performing circular motion in a vertical plane, thereby protecting the centrifuge tube. By providing an adjustment assembly 4, when the vortex oscillator is not working, the upper oscillation disk 101 can be adjusted to descend through the adjustment assembly, so that the avoidance groove 111 and the placement groove 112 can jointly fix the centrifuge tube.

During the use of the vortex oscillator, the motor is started, and the motor rotates and drives the lower oscillation disk 102 to make a circular motion in the vertical plane, causing vortex oscillation in the centrifuge tube.
