Abstract

The invention discloses a gas sampling device, which belongs to the technical field of gas sample detection in modified atmosphere packaging. The gas sampling device includes a hollow needle, an air guiding part, a holding part and a positioning protection seat. The air inlet, the end of the hollow needle away from the sharp part is connected to the air guide part, the holding part is fixed on the outer peripheral surface of the hollow needle, and the positioning protection seat and the holding part are connected with a reset deformation part; the positioning protection seat is installed in the hollow The needle and the positioning protection seat have a protection position covering the sharp part and a sampling position away from the sharp part, the positioning protection seat is suitable for moving between the protection position and the sampling position, and the reset deformable part tends to move the positioning protection seat to the protection position. The gas sampling device of the present invention can realize the integrated operation of piercing holes for gas sampling, prevent gas leakage, improve the accuracy of gas sampling, avoid accidental injury of sharp parts, and has the characteristics of simple operation, accurate sampling, good reproducibility and low cost.

Description

technical field [0001] The invention relates to the technical field of gas sample detection in modified atmosphere packaging, in particular to a gas sampling device. Background technique [0002] At present, in the food, pharmaceutical or chemical industry, modified atmosphere packaging is often used to seal or keep food or other products fresh, such as products in hard packaging (soy sauce, edible vegetable oil, beverages, etc.) or products in soft packaging (boxed Stewed food, bagged potato chips, etc.), generally by injecting suitable gas (such as nitrogen and carbon dioxide, etc.) into the packaging bag or packaging container to discharge the target gas (such as oxygen), so that the shelf life of the goods is extended. When it is necessary to detect the gas content and composition in the modified atmosphere package, the gas sample in the package is usually sucked out with a sampling tube, and then sent to the gas analyzer for gas sample analysis. [0003] However, when ...
