The invention belongs to the technical field of aerosol sampling, and particularly relates to an air aerosol sampler and a using method thereof.The air aerosol sampler comprises a spherical frame, a carrier block, a base, a sampling pipe, an induced draft fan, an air inlet pipe, a scraping motor, a driving lead screw, a driven scraping plate, a feed liquid box and a liquid supply pipe; a carrier block is installed on the lower portion of the spherical frame, a base is installed on the lower portion of the carrier block in a threaded connection mode, a sampling pipe with an air inlet pipe is fixed to the upper end of the base, an induced draft fan is installed at the top end of the sampling pipe, a scraping motor is installed in the base in an embedded mode, a driving lead screw is installed at the output end of the scraping motor, and a driven scraping plate is installed on the outer side of the driving lead screw. According to the invention, the spherical frame, the carrier block and the base form a self-adaptive carrier system, and the sampling pipe is always in a vertical state by utilizing gravity, so that the sampling is smoothly carried out; automatic spraying of feed liquid and automatic scraping and collecting of the feed liquid can be achieved, and the requirement for multiple times of continuous sampling is met.
