The resuspension sampler can stably generate polydisperse dust particles with certain mass concentration and particle size distribution in a laboratory and perform sampling detection. Therefore, the method plays a great role in the atmospheric particulate matter source resolving work. The resuspension sampler generally comprises a particulate matter resuspension system and a particulate matter detection system, wherein the resuspension system comprises an air source part, a particulate matter generation part and a resuspension part, dust to be detected is uniformly mixed in a mixing barrel after being generated in a particle non-generation part under the action of compressed air in the operation process, and then the particulate matter is sampled, detected and analyzed by the detection system. However, in the operation process of the equipment, the dust to be detected exists in the mixing barrel in a suspension state after entering the mixing barrel, at the moment, a small part of dust is adsorbed on the surface of the mixing barrel and cannot be completely extracted by a sampling part due to electrostatic adsorption or the influence of the smoothness processed by the barrel wall of the mixing barrel, and finally, the dust needs to be cleaned up manually so as not to influence the next test. Generally, such devices are large in size, and if the devices are cleaned by manpower, the devices are time-consuming and labor-consuming, and the cleaning effect is not ideal.
