When filling air, the positioning block 34 can slide inside the limiting groove 3. When the air collecting chamber 11 is filled with enough air, the rubber sheet 31 can slide to the bottom of the air collecting chamber 11. This step can be used to discharge the waste gas inside the air collecting chamber 11 through the action of the rubber sheet 31 before multi-point sampling and collection of air, thereby reducing the impact of waste gas on the monitoring results.

[0029] like Figure 2-3 As shown, a sieve plate 6 is fixedly connected to the middle of the air guide box 14; during operation, when the air guide tube 15 is used to fill the air into the atmosphere collecting box 1, the sieve plate 6 can be used to perform preliminary filtration on the air. This step can reduce the occurrence of external impurities entering the air collecting chamber 11 when collecting the air, thereby improving the accuracy of air monitoring.

[0030] like Figure 1-2 As shown, a plurality of rubber pads 7 are fixedly connected to the middle of the atmosphere collection box 1; during operation, when the atmosphere collection box 1 is used for operation, it can be connected to the outside world through the rubber pads 7. This step can reduce the possibility of tipping over of the atmosphere collection box 1 when the atmosphere collection box 1 is used for air sampling.

[0031] Working principle: during operation, when it is necessary to perform multi-point sampling and collection of air, the atmosphere collection box 1 can be placed at the sampling position, and then the rubber head 16 can be pressed, so that the first spring 18 can be compressed, and the gas inside the gas collecting chamber 11 can be discharged to the outside, and then the restraint on the rubber head 16 can be released, so that the rubber head 16 can be restored to its original shape under the action of the first spring 18, so that the air can enter the gas collecting chamber 11 through the gas collecting head 19, and then the position of the atmosphere collection box 1 can be moved, and at the same time, the slide rail 13 can be slid in the middle of the slide groove 12, so that the air guide box 14 can be placed at the end of the gas collecting chamber 11 at different positions, and then the above operation can be performed again. This step can be performed by setting the interior of the atmosphere collection box 1 There are multiple groups of air collecting cavities 11, which can be used for multi-point sampling and collection when sampling the air, so that when performing data analysis on the air inside the factory, the inaccurate sampling data analysis caused by the continuous flow of air can be reduced. When performing multi-point sampling on the air, after the slide rail 13 is slid inside the slide groove 12, the pressing piece 24 can be pressed, and then the positioning piece 21 can be brought into contact with the side of the slide rail 13 under the action of the support rod 23, so that the position of the air guide box 14 can be fixed. When the position of the air guide box 14 needs to be slid, the pressing of the pressing piece 24 can be released, and then the positioning piece 21 can be retracted under the elastic force of the second spring 22. This step can be performed when multi-point sampling of the air is required. The function of 21 is to reduce the sliding of the slide rail 13 when sampling the air, thereby reducing the situation of insufficient sampling air caused by the sliding of the slide rail 13 during the air sampling process, thereby improving the accuracy of multi-point air sampling analysis. When sampling the air, the telescopic rod 32 can be extended, and then the positioning block 34 can be slid inside the limiting groove 3 through the telescopic rod 32, so that the rubber sheet 31 can discharge the air inside the air collecting chamber 11 to the outside. When filling the air into the air collecting chamber 11, the positioning block 34 can slide inside the limiting groove 3. When the air collecting chamber 11 is filled with enough air, the rubber sheet 31 can slide to the bottom of the air collecting chamber 11. This step can be performed in multiple air sampling. Before point sampling and collection, the waste gas inside the gas collecting chamber 11 can be discharged through the action of the rubber sheet 31, thereby reducing the influence of the waste gas on the monitoring results. Through the sliding action of the positioning block 34 inside the limiting groove 3, after the air collection is completed, the gas inside the gas collecting chamber 11 can be conveniently discharged for monitoring, thereby improving the collection efficiency when sampling and collecting the air. When the gas collecting chamber 11 is used to perform multi-point sampling and collection of the air, the baffle 41 can be slid inside the sheet groove 4. When the rubber head 16 is used to fill the gas collecting chamber 11 on one side, the baffle 41 can be used to cover the end of the gas collecting chamber 11. When the air is collected at multiple points, the baffle 41 can be gradually pushed. This step can be achieved through the action of the baffle 41.The end of the air collecting chamber 11 can be covered, so that when the air is sampled and collected at multiple points, the external debris entering the air collecting chamber 11 and causing air pollution can be reduced, thereby improving the accuracy of air monitoring. After using multiple groups of air collecting chambers 11 to sample and collect the air, the card column 5 can be placed in the middle of the atmosphere collection box 1, and the baffle 41 can be limited by the meshing action between the bottom of the card column 5 and the baffle 41. This step can reduce the sliding of the baffle 41 inside the sheet slot 4 after the air is sampled and collected, thereby improving the accuracy of air monitoring. This can reduce the contamination of the air in the air collecting chamber 11 by external impurities. When the air guide tube 15 is used to fill the air into the air collecting box 1, the sieve plate 6 can be used to perform preliminary filtration on the air. This step can reduce the external impurities from entering the air collecting chamber 11 when collecting the air, thereby improving the accuracy of air monitoring. When the air collecting box 1 is used for work, it can be connected to the outside world through the rubber pad 7. This step can reduce the tipping of the air collecting box 1 when the air is sampled.
