[0002] Atmospheric particulate matter is a general term for various solid and liquid particulate matter in the atmosphere. Various particulate matter is evenly dispersed in the air to form a relatively stable and large suspension system. Atmospheric particulate matter is an important basis for judging the health of the atmospheric environment. When monitoring the atmosphere, a sampling device is required to sample atmospheric particulate matter. The main principle is to set up an air intake structure to guide the air to the filter membrane, which intercepts the particulate matter in the air, and then detect the particulate matter collected on the filter membrane to understand the environmental conditions and changes.

[0003] The existing technology, such as the utility model with authorization announcement number CN217403914U, realizes collecting multiple samples at one time.

[0004] Currently, there is a lack of a device that can achieve equally spaced and adjustable sampling samples. Utility Model Content
