A sampling and testing device for household chemicals

Abstract

The application belongs to the technical field of sample collection, and particularly relates to a sampling and detecting device for daily chemicals, which comprises a suction pipe assembly, a suction pipe conveying assembly, a negative pressure generating assembly, a poking assembly, a sampling box body, a rack and a conveying assembly, the suction pipe assembly is located in the suction pipe conveying assembly, the suction pipe conveying assembly is arranged in the rack, and the negative pressure generating assembly is arranged in the rack. The suction pipe conveying assembly can drive the suction pipe assembly to ascend and descend. In the ascending and descending process of the suction pipe assembly, through linkage of the poking assembly, the negative pressure generating assembly can clamp the hose part when the suction pipe assembly descends and release the hose part when the suction pipe assembly ascends. Through clamping and rolling contact of the negative pressure generating assembly on the hose part, the air flow in the suction pipe assembly can be actively controlled, so that negative pressure is generated in the suction pipe assembly and external fluid is attracted into the suction pipe assembly.
