AI Technical Summary
Existing pesticide residue detectors use open or semi-open detection structures. When external light enters the detection area and overlaps with the detection light, non-target spectral noise is mixed into the detection signal, resulting in baseline drift, decreased signal-to-noise ratio, and deviations or even misjudgments in the detection results.
A pesticide residue detector was designed. It uses an electric telescopic rod to move a light shield to cover the spectral scanner, a rotating connecting cylinder to block light, and a waterproof motor and nozzle assembly for cleaning, ensuring a stable detection process and effective cleaning.
It effectively blocks external light during the detection process, reduces spectral noise interference, improves the signal-to-noise ratio, and ensures the accuracy and cleanliness of the detection results.
