Indoor environment detection air collection device

Abstract

The utility model discloses an indoor environment detection air collection device, and belongs to the technical field of indoor environment detection, and the indoor environment detection air collection device comprises a storage box and an implementation structure, and the storage box is internally provided with a cylindrical storage cavity and a vertical storage cavity; the implementation structure comprises a transparent collector bottle placed in the cylindrical containing cavity and a gas conveying assembly placed in the vertical containing cavity. When the indoor environment detection air collecting device is used, a pull rod of an injector in the air conveying assembly is pulled firstly, after the air pressure of an inner cavity of an air box is reduced, a second plugging ball originally plugged at the narrow opening end of a second circular truncated cone cavity compresses a second spring, and air in the indoor environment is continuously extracted into the injector through the second circular truncated cone cavity; and finally, an operator presses a pull rod of an injector, so that the collected gas jacks a first blocking ball and then makes contact with the alcohol solution, and finally the indoor air quality can be judged by detecting and calculating the content of particulate matter on the dust removal net and the content of formaldehyde dissolved in the alcohol solution.
