[0021] Compared with the prior art, the advantages and positive effects of this application are:

[0022] 1. In the present application, before the test, the automatic telescopic rod is controlled so that its output end drives the push plate to move. At this time, multiple filter papers are placed inside the filter paper frame, and then the automatic telescopic rod is controlled so that its output end presses the filter papers through the push plate. When the test is carried out, the switch of the bidirectional motor is turned on, and the power is turned on to drive the threaded rod to rotate forward.

[0023] 2. In the present application, when the filter paper collects samples of particulate matter in the air, the external power supply of the driving motor is turned on, and then the output shaft of the driving motor drives the rotating rod to rotate, further causing the fan blades to rotate. When the fan blades rotate, the external air is sucked into the interior of the collection box, further causing the filter paper to collect samples of particulate matter in the air. When the rotating rod rotates, it drives the ring to rotate, further causing the multiple cutting blades to rotate. When the air is inhaled, the leak plate filters large objects. At the same time, the large objects adsorbed on the outer surface of the leak plate are shredded by the rotating multiple cutting blades, preventing the large objects from blocking the leak holes on the leak plate and affecting the collection of the filter paper, thereby improving the practicality of the device.
