AI Technical Summary
Existing pesticide residue detection sampling devices are highly sealed, which affects the ease of cleaning and makes it difficult to quickly prepare for resampling.
Design a sampling device comprising a box assembly, a filter assembly, and a top cover assembly. The box assembly contains a liquid outlet pipe and a support rim, and the filter assembly has a fixing frame and a filter screen. The sample basket is rotated by a hand crank to accelerate dissolution, and the modular design supports separate cleaning.
It achieves efficient and low-cost pesticide residue sampling, avoids cross-contamination, shortens extraction time, is suitable for field or laboratory environments, lowers the threshold for use, and improves cleaning efficiency.
