AI Technical Summary

Technical Problem

In existing luteolin detection technologies, test tube cleaning is time-consuming, laborious, and fragile, manual cleaning cannot be thorough, the detection device lacks constant temperature function, and there is a significant risk of waste liquid leakage.

Method used

The system employs a sample placement device, a temperature control device, a switching component, and a testing device. A servo motor drives an octagonal plug to agitate the sample liquid, an electric actuator controls the liquid flow from the test tube, a temperature-controlled liquid exchanges with thermal grease to maintain the temperature, a cleaning solution is agitated in the test tube for cleaning, and waste liquid is collected and discharged.

Benefits of technology

It enables automated cleaning and constant temperature testing of test tubes, reduces the risk of waste liquid leakage, and improves the safety and accuracy of testing.

Abstract

This invention discloses a method and system for detecting luteolin, relating to the field of luteolin detection technology. The system includes a sample placement device, a temperature control device, a switching component, a testing device, and a liquid holding device. A servo motor drives the outer octagonal interface to reciprocate via a transmission shaft. The outer octagonal interface, through an ultraviolet detector, drives the test hemisphere to reciprocate, achieving a slight shaking and agitation of the sample solution, ensuring better mixing of the various components and preventing precipitation. An electric actuator on the side of the transmission shaft drives the connector base to slide downwards, causing the inner octagonal plug to be pulled out from the lower end of the outer octagonal interface. The sample placement base is then manually opened, and the test hemisphere is manually rotated so that the opening of the transparent test tube faces downwards. The sample solution inside the transparent test tube flows downwards through the gap in the rubber flap. The flowing sample solution mixes together and flows from the lower opening of the concave surface of the hemisphere into the lower half of the heat-insulating shell for collection. The collected mixture is then discharged through the drain port.
