Abstract

The invention discloses a gas sampling device, and belongs to the technical field of modified atmosphere packaging gas sample detection. The gas sampling device comprises a hollow needle, a gas guideportion, a gripping portion and a positioning protective seat. The hollow needle is provided with a sharp portion, a gas inlet is formed in the sharp portion, the end, which is far away from the sharpportion, of the hollow needle is connected with the gas guide portion, the gripping portion is fixedly arranged on the outer peripheral surface of the hollow needle, and a reset deformation componentis arranged between the positioning protective seat and the gripping portion in a connected manner; the hollow needle penetrates the positioning protective seat, the positioning protective seat has aprotective location and a sampling location, wraps the sharp portion when positioned at the protective location, is far away from the sharp portion when positioned at the sampling location and is suitable to move between the protective location and the sampling location, and the reset deformation component tends to enable the positioning protective seat to move to the protective location. The gassampling device has the advantages that hole pricking and gas collecting integrated operation can be carried out by the gas sampling device, gas leakage can be prevented, and the gas sampling accuracy can be improved; accidental injury due to the sharp portion can be prevented, and the gas sampling device is easy and convenient to operate, accurate in sampling, good in reproducibility and low incost.

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 ...
