Abstract

The invention discloses a food fast detector with a continuous sampling injection function, and particularly relates to the technical field of food fast detection. The food fast detector comprises a driving motor, a fixed disc, a liquid inlet device and an oscillation device, and the output end of the driving motor is fixed to the lower portion of the fixed disc. The oscillation device comprises afixed seat. The liquid inlet device comprises an outer barrel, a first liquid storage barrel, a piston barrel, a second liquid storage barrel, a sample liquid barrel and a sample inlet pipe. The outer cylinder body is elastically connected with the fixed seat. The first liquid storage cylinder is sleeved with the outer cylinder body, a first through hole is formed in the first liquid storage cylinder, the first liquid storage cylinder is provided with a piston rod, and the end of the piston rod is fixed to the piston. The piston is arranged in the piston cylinder in a sliding mode, the pistoncylinder is fixedly communicated with the second liquid storage cylinder, the second liquid storage cylinder is provided with a sealing plug, and a second through hole is formed in the side wall of the second liquid storage cylinder. One end of the sample injection pipe is communicated with the sample liquid cylinder, and the other end is communicated with the first liquid storage cylinder. The food fast detector has the advantage that the liquid can be continuously fed in the centrifugal process of the sample solution.

Description

technical field [0001] The invention relates to the technical field of quick food inspection, in particular to a quick food inspection instrument with the function of continuous and uninterrupted sampling. Background technique [0002] Rapid detection technology is widely used in medical diagnosis, bacterial detection, inspection and quarantine, food safety monitoring such as environment and pesticide residues, veterinary diagnosis, drug detection, drug screening, dynamic monitoring of biological reaction process and scientific research, including biologically carried pathogens, Rapid diagnosis and detection of cancer markers, heart disease markers, various hormones, illegally added / pesticide / veterinary drug residues, etc. Among them, fast detection technology is widely used in the field of food testing, such as using kits for qualitative or semi-quantitative detection of illegal additions / pesticides / veterinary drug residues in food testing sample liquids, and using portable...
