Description

Technical Field

[0001] The utility model relates to the technical field of pesticide detection, in particular to a fruit and vegetable pesticide detection device. Background Art

[0002] In recent years, with the improvement of people's living standards, people have paid more and more attention to food safety issues. A detector is a kind of detection instrument for pesticide residues in food. When using the detector to detect fruits and vegetables and other foods, it is often necessary to squeeze the fruits and vegetables into juice and then conduct the detection.

[0003] A fruit and vegetable pesticide detection device described in the publication number CN217733175U, through the provided storage barrel, extrusion rod, mounting plate, electric push rod and drive assembly, starts the electric push rod to drive the extrusion rod and the extrusion plate to move down to squeeze the vegetables, so that the water can fall from the discharge pipe to the detection test tube. Starting the drive assembly includes a bidirectional motor, a threaded lead screw, a mounting block and a guide rod. Starting the bidirectional motor, the bidirectional motor can drive the threaded lead screw to rotate. Combined with the action of the guide rod, the mounting block and the storage barrel can be moved, thereby realizing the ability to move and add materials to the reagent tubes in a row one by one, which is more convenient. Among them, the caliber of the discharge pipe is small, which can control that when the extrusion rod does not move down to squeeze, the water will not fall automatically, and the filter holes of the filter plate are very small, effectively solving the problems raised in the background art and improving the detection accuracy and detection efficiency. However, the prior art still has defects:

[0004] 1. In the prior art, the storage barrel is fixedly connected with the mounting block, so that the storage pipe can only slide along the guide rod, which is not convenient to disassemble and clean, affecting the next detection use.

[0005] 2. In the prior art, the fruits and vegetables inside the storage barrel are squeezed by the extrusion rod to make their juice flow out from the discharge pipe. However, this squeezing method can only squeeze out the internal juice, and the pesticide residues may still exist on the surface of the fruits and vegetables, affecting the detection accuracy. At the same time, the amount of the discharged liquid cannot be controlled, which may lead to too much liquid being squeezed in at one time. Content of the Utility Model
