[0002] my country is a major tea planting, processing, consumption and exporting country. With the development of social economy and the improvement of material living standards, tea, as a green health product, is widely favored by consumers. Acequinoxaline is a commonly used insecticide and miticide, usually used to control the growth and reproduction of tea pests and mites. However, the acequinoxaline residue in tea may pose a potential threat to human health. Although tea can kill some mites and pesticide residues during the brewing process, long-term intake of tea containing pesticide residues may have adverse effects on the human body. Therefore, the acequinoxaline content of tea needs to be tested before it is sold.

[0003] When detecting chlorfenapyr in tea leaves, it is usually necessary to crush the tea leaves first and then mix them with an extraction solvent. The chlorfenapyr residues in the crushed tea leaves are easier to distribute evenly in the solvent. However, the prior art usually requires staff to crush the tea leaves in advance and then put them into an extraction device for mixed extraction with the solvent. The steps are relatively cumbersome, and the tea leaves need to be separated when the solvent is extracted, thereby reducing the detection efficiency of the tea leaves. Utility Model Content
