[0002] Food, soil, and water quality are gradually polluted by industrial waste gas, wastewater, and waste residue. Some people even use industrial wastewater directly to irrigate crops, resulting in the enrichment and accumulation of heavy metals such as cadmium, copper, arsenic, chromium, mercury, nickel, iron, aluminum, zinc, and manganese in the soil arable layer. The phenomenon is more serious in urban suburbs, especially in urban areas. Coupled with the large-scale use of inorganic chemical pesticides, the heavy metal content in vegetables and fish is seriously exceeded. To detect whether the heavy metals in food exceed the standard, a food heavy metal detector is needed to detect it.

When the detector is not used for a long time, a large amount of dust will erode it, and when the detector is placed, an accidental collision will also cause it to be damaged, so its practicality is poor. In addition, a food heavy metal detector in the prior art mixes the powder residue after the food is crushed with the medicine during detection, and the detection is performed by the detector. The traditional mixing method requires manual mixing, and it cannot automatically stir and mix when placed in the detector body, resulting in a lot of time consumption and poor practicality.
