Problems solved by technology
[0002] At present, the particulate matter pollution in the atmosphere is serious, seriously affecting people's work, life and health. In order to understand the air quality in various places, it is necessary to regularly collect and test the air at each testing point
[0003] Moreover, the existing sampler has a single function when used, and can only sample a single type of particulate matter, which cannot meet various needs; at the same time, after the existing sampler finishes sampling, the electronic adsorption screen is very inconvenient to take out, and then The sampled particles will affect the detection results after being left for a long time. Therefore, in view of the problems in the prior art, it is necessary to propose a comprehensive sampler for ambient air particles

The invention belongs to the technical field of samplers, and particularly relates to an ambient air particulate matter comprehensive sampler, which comprises a working box, wherein a supporting baseis fixedly connected to the bottom of the working box, a handle is movably connected to the top of the working box, an exhaust fan is fixedly installed on the inner top wall of the working box, the air inlet of the exhaust fan communicates with an air inlet pipe in a sealed mode, the other end of the air inlet pipe communicates with a connecting piece arranged at the top of the working box in a sealed mode, the other end of the connecting piece is in threaded connection with an air suction head, a dustproof cover is fixedly installed at the top of the air suction head, the output port of the exhaust fan communicates with an air conveying pipe in a sealed mode, the other end of the air conveying pipe is hermetically communicated with a spring pipe, the other end of the spring pipe is hermetically communicated with an upper clamping pipe, and an air outlet pipe is arranged at the inner bottom of the working box. The ambient air particulate matter comprehensive sampler provided by the invention achieves the effect of manually and quickly taking out a sampling product, and avoids the influence of long-time placement of the sampling product on a detection result.
