Description

Technical Field

[0001] The utility model relates to the technical field of aerosol generation, in particular to an anti-leakage dust aerosol generation mechanism. Background Art

[0002] When conducting research in the field of environmental science on particle purification and in the field of medicine on dust pathology, a stable atmospheric environment that can simulate the presence of particles of different concentrations is often needed, which requires the use of an aerosol generator. Currently, common aerosol generators on the market mainly use liquid as raw material, which is atomized and then sprayed to simulate particulate environmental pollution; however, in the actual environment, particulate matter mainly exists in the form of dry particles, so in many cases, solid dust is needed to create dust aerosols to simulate polluted environments.

[0003] The existing Chinese utility model patent, application number CN201020145532.1, discloses a turntable dust aerosol generating device, which specifically includes a stirring motor controlled by a computer to drive the stirring blade in the flow bin to rotate, stir the internal dust evenly and transport it to the pit on the rotating disk below the bottom leakage hole of the flow bin, which is specially used to carry dust. The computer-controlled negative pressure generator sucks the dust carried in the pit on the rotating disk into the powder spraying dissolution chamber through the negative pressure powder suction pipe to form a dust aerosol, and then transports it to the aerosol detection experimental cabin for detection and experiment. When the computer-controlled turntable motor rotates at different speeds and selects a rotating disk with different pit widths, the amount of dust transported to the negative pressure powder suction pipe is different, and the concentration of the dust aerosol formed by flowing into the powder spraying dissolution chamber is also different. Therefore, by selecting a rotating disk with a suitable pit width and a suitable rotating disk speed and keeping it constant, a dust aerosol with a stable concentration can be continuously and accurately generated.
