Sealing structure of toxic gas sampler

Abstract

The utility model discloses a sealing structure of a poisonous gas sampler, which relates to the technical field of poisonous gas sampling and comprises a sampling bottle for sampling poisonous gas. The sampling bottle is clamped and mounted on a supporting plate in the case; an air inlet channel is detachably mounted at the top of the sampling bottle; the air inlet channel is hermetically connected with the flow controller shell through a connecting pipe; an air outlet pipe is installed in the flow controller shell in a matched mode. A plurality of air outlet holes are formed in the air outlet pipe; a spiral blade is integrally arranged on the outer wall of the air outlet pipe; the bottom of the air outlet pipe is hermetically connected with the connecting pipe; the automatic sampling effect is achieved by controlling the sampling pump through the controller, poisonous gas extracted by the sampling pump is conveyed into the inner cavity of the coarse filter cover through the connecting pipe, residual impurities in the poisonous gas are effectively filtered through the filter pipe, and the situation that the impurities enter a sampling bottle, and the sampling quality of the poisonous gas is affected is avoided.
