Description

Technical Field

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

[0002] Pesticides are widely used in modern agricultural production as an important means to increase agricultural production and protect crops from pests. However, improper or excessive use of pesticides may lead to pesticide residues in agricultural products, which in turn poses a potential threat to human health. Therefore, testing pesticide residues in food to ensure food safety has become an important task in the field of food safety testing.

[0003] At present, there are many ways to detect pesticide residues in food. Among them, the water washing method is to soak the food sample in clean water for a period of time, and use the solubility of pesticides in water to dissolve the pesticide residues from the surface or inside of the food. However, a single soaking method is likely to cause uneven dissolution. In addition, if the food sample is not washed sufficiently, the pesticide residues may not be completely dissolved, which will affect the test results. Therefore, we propose a food pesticide residue detection device. Utility Model Content

The food sample to be tested is contained, and the push plate 52 is pressed to make the push rod 51 push the connecting cover 54 and the net cylinder 4 downward along the sliding hole on the top of the cylinder cover 2. At the same time, the push plate 52 squeezes the compression spring 53. At this time, the cleaning liquid in the detection cylinder 1 contacts the food sample through the mesh holes on the net cylinder 4. When the push plate 52 is released, the compression spring 53 causes the connecting cover 54 to move the net cylinder 4 upward to its original position. After repeated operations, the cleaning liquid can fully wash the food sample. An auxiliary unit 6 is arranged at the bottom center of the detection cylinder 1. The auxiliary unit 6 consists of a stirring motor 61, a sealed bearing 62 and a stirring paddle 63. The stirring paddle 63 is arranged at the bottom center of the detection cylinder 1.

[0018] The working principle of the utility model is as follows: when in use, first insert the detection tube 1 into the seat hole 9 on the base 3, then pour an appropriate amount of external cleaning liquid into the detection tube 1, then put the food sample that needs to be tested for pesticide residues into the net tube 4, and thread the net tube 4 to the bottom of the connecting cover 54, then insert the net tube 4 into the inside of the detection tube 1, and thread the tube cover 2 to the top of the detection tube 1, by pressing the push plate 52, the push rod 51 pushes the connecting cover 54 and the net tube 4 downward along the sliding hole at the top of the tube cover 2, and at the same time, the push plate 52 squeezes the compression spring 53, at this time, the cleaning liquid in the detection tube 1 contacts the food sample through the mesh holes on the net tube 4, and when the push plate 5 is released, the food sample is in contact with the food sample. 2, under the action of the compression spring 53, the connecting cover 54 drives the net cylinder 4 to move upward to the original position. After repeated operations, the cleaning liquid can fully wash the food sample, thereby washing away the pesticide residues on the food sample. In addition, the user can also start the stirring motor 61 through the external controller, so that the output shaft of the stirring motor 61 drives the stirring paddle 63 to fully stir the cleaning liquid at the bottom of the detection cylinder 1, so that the pesticide residues in the cleaning liquid are evenly mixed. After the washing and stirring operations, the cleaning liquid in the detection cylinder 1 already contains the pesticide residues on the food sample.
