Purging and trapping automatic sample injector

The utility model discloses an automatic sample injector for purging and trapping, which comprises a storage cylinder, a top cover and a stirring component, the top cover is detachably mounted on the upper surface of the storage cylinder, a rotating groove is formed in the upper surface of the top cover, the stirring component is movably mounted in the rotating groove, and a sealing cover is detachably mounted on the upper surface of the stirring component. Through the design of the stirring assembly, when all samples in the storage cylinder are stirred, the samples can rotate and revolve around the edge of the storage cylinder off the center at the same time, so that the samples can be in full contact with helium or nitrogen, and the volatilization amount of volatile organic matters in the samples can be increased; and the content of carried organic matters is increased in the purging process of helium or nitrogen. 本实用新型公开了一种吹扫捕集自动进样器，包括存储筒、顶盖、搅拌组件，存储筒上表面可拆卸安装有顶盖，顶盖上表面开设有转动槽，转动槽内活动安装有搅拌组件，搅拌组件上表面可拆卸安装有密封盖。本申
