Description

Technical Field

[0001] The utility model relates to the technical field of pesticide detection, in particular to an intelligent pesticide residue detection device. Background Art

[0002] Pesticide residues in agricultural products, food, and other items are a significant potential risk to human health. China's annual pesticide usage in agricultural production ranks first in the world, with organophosphorus pesticides, in particular, accounting for 80% of total pesticide use. Recent data indicates that over 14% of agricultural products sold in farmers' markets in major provincial-level cities in China failed to meet standards for organophosphorus pesticides in the first quarter. Greenhouse-grown produce is particularly prone to pesticide residues. Direct pesticide application to agricultural products can also lead to internalized pesticide residues in the fruit flesh. Therefore, testing for pesticide residues must not only focus on the surface of the produce but also on the flesh itself, requiring rapid and accurate detection technology.

[0003] The existing pesticide residue detection device has a low level of intelligence and requires frequent manual operation during detection. First, the test vegetables are cut and soaked with detection liquid to remove the pesticides on the vegetables. Then the detection liquid is placed in the detection tube and placed in the detector for detection. The process is complicated and the detection process is time-consuming and labor-intensive. At the same time, each time the pesticides on the surface of the vegetables are removed, multiple beakers are required for the pesticide removal step. The beakers need to be cleaned after each test. There are many cleaning steps after the pesticide residue test. The detection equipment is complex to use and has low intelligence. Therefore, a detection device for rapid detection of the agricultural industry is needed. Utility Model Content
