[0002] Atmospheric particulate matter is a general term for all kinds of solid and liquid particulate matter present in the atmosphere. Dust, smoke, fog, and haze that we commonly see all fall under the category of atmospheric particulate matter. Because atmospheric particulate matter can cause harm to people, it is necessary to collect particulate matter to detect whether it exceeds the standard. Current particulate matter collection devices refer to devices that draw in external air and filter and collect pollutant particles floating in the atmosphere. However, existing sampling devices require frequent shutdowns to replace the sampling filters when sampling multiple sets of the same or different types of particulate matter. This process is time-consuming and labor-intensive, and shutdowns halt the sampling process, resulting in low sampling efficiency. Therefore, we need to propose an atmospheric particulate matter sampling device. Utility Model Content
