Description

Technical Field

[0001] The utility model relates to the technical field of food detection and sampling equipment, in particular to a food safety detection and sampling device. Background Art

[0002] Food safety testing is a vital task that aims to ensure food safety and protect the health and rights of consumers. Food safety testing is mainly based on relevant national and regional laws and regulations to formulate testing standards and test and analyze harmful substances in food. The scope of food safety testing is wide, including pesticide residues, additives, heavy metals, microorganisms, pathogenic bacteria and other aspects. These testing items cover various risks that may exist in the food production process to ensure that food meets safety standards before entering the market.

[0003] At present, most of the food sampling devices on the market are machine sampling, which is inconvenient for sampling liquid food. At the same time, there is no detachable hose, which is very inconvenient for sampling different liquids. In addition, the structure is relatively complex and the operation is cumbersome, which is not suitable for large-scale use. Based on these problems, Chinese patent CN206387607U discloses a food safety detection sampling device, which is equipped with a detachable hose and can sample different liquid foods. The scope of application is relatively large. At the same time, a sealing ring is provided to seal and preserve the liquid in the protective shell so that the liquid will not leak out and cause harm to the experiment. A buffer ring is provided to prevent the head cover from damaging the equipment during the squeezing process. The equipment has a relatively simple structure, a low operation difficulty coefficient, and is relatively convenient to clean and maintain.

[0004] The hose at the bottom of the sampling device is directly connected to the atmosphere, so the liquid food inside the protective shell will deteriorate when in contact with the atmosphere, which will also affect the accuracy of the test results. Utility Model Content

At this time, the liquid food will pass through the ring. A large amount of gas is stored in the gas sleeve. When the staff holds the gas sleeve tightly, the gas in the gas sleeve will be transported to the top of the first piston through the gas pipe and the joint. At this time, the first piston will slide downward due to the compression of the gas. At the same time, the sleeve on the support rod at the bottom of the slide rod will also slide downward. Subsequently, a gap will be generated between the top of the outer wall of the conical block and the inner wall of the conical cavity inside the ring. By setting a simple connection method between the sampling tube and the top ring, the disassembly and assembly steps of the top cover are more convenient and quick, and it is also convenient to clean the inside of the sampling tube.
