Abstract

This utility model relates to the field of pesticide detection, and more particularly to a rapid pesticide detection device utilizing quantum dot microsphere fluorescence. It includes a base, a placement box, a display screen, a top cover, and a test seat. The placement box is slidably connected to the lower part of the base, and the top cover is rotatably mounted on the upper rear part of the base. The display screen is connected to the inner side of the top cover, and the test seat is connected to the inner side of the upper part of the base. The top cover is rotatably connected to the upper left part of the test seat. This utility model involves placing a container containing reagents onto a turntable, then crushing fruits and vegetables using a crushing rack, allowing the crushed sample to flow into the container for sampling. The turntable rotates, causing the next container to rotate below the filter for further sampling. During rotation, the turntable moves up and down under the action of protrusions and connecting blocks, vibrating and mixing the reagents and samples. This allows for switching containers to sample multiple samples while automatically mixing the solvent and sample, facilitating rapid detection, reducing labor costs, and improving detection efficiency.
