Technical Field

[0001] The utility model relates to the technical field of residual pesticide detection, in particular to a residual pesticide detection device for fruits and vegetables. Background Technique

[0002] At present, many fruits and vegetables need to be sprayed with pesticides to prevent insects from eating the vegetables and improve the yield of vegetables. However, this kind of pesticide is also harmful to the human body. If it is not cleaned thoroughly, it will cause food poisoning and pose a threat to human health. In view of the above deficiencies, it is necessary to design and develop a residual pesticide detection device for fruits and vegetables to make up for the above shortcomings.

[0003] When the existing residual pesticide detection device for fruits and vegetables detects the samples of fruits and vegetables, it only rinses the samples simply, and cannot rinse the pesticides that may remain on the surface of the samples of fruits and vegetables cleanly, resulting in certain errors in the detection results. Moreover, the existing residual pesticide detection device for fruits and vegetables does not have a filtering function itself, and external equipment needs to be used to filter the samples to be detected to avoid the residues of fruits and vegetables residues in the mixed liquid, which may damage the detection structure.
