[0027] In a preferred embodiment: the outer wall of the inserting plate 7 is fixedly equipped with an adsorption layer, and the inserting plate 7 is made of a foamed board.

[0033] Working principle: First, the user picks up the plug plate 7 to weigh it, then aligns the plug plate 7 with the docking groove 11 and presses the plug plate 7 to make the plug plate 7 enter the vacuum tube 2. The material of the plug plate 7 is elastic so that the outer wall of the plug plate 7 fits tightly with the inner wall of the docking groove 11 to ensure that the extracted air cannot leak through the docking groove 11. Then, the pull rod 3 is pulled, and the pull rod 3 will extract the high-pressure air inside the vacuum tube 2 through the ventilation pipe 12. At the same time, the pull rod 3 pulls the piston 14 to slide along the inner wall of the vacuum tube 2 through the wire rope 13, and at this time, the vacuum tube 2 will The outside air is extracted, and the air contacts the adsorption layer to separate the aerosol from the air, thereby achieving the sampling effect. The marking ruler 6 will mark the moving distance of the piston 14, and the user can collect the data of the movement of the piston 14 according to the scale. After the sampling is completed, the pull rod 3 is pushed back to allow the high-pressure air to be discharged into the vacuum cylinder 2 again, and the piston 14 is reset under the transfer of the high-pressure air. At the same time, a pulling force is generated on the wire rope 13, which makes the wire rope 13 taut to ensure the subsequent use of the detector. Finally, the user removes the plug plate 7 and re-weighs the plug plate 7.
