The inner wall of the irregular bag sleeve is sleeved and contacts the middle end of the outer wall of the reagent tube.

[0015] A method for using a field environment sampling device for indoor environmental pollutant detection comprises the following steps:

[0016] Step 1: The staff manipulates the pull block to push it to both sides, the pull block drives the box door to move, the box door drives the sliding plate to move, the sliding plate drives the connecting block to move, the connecting block drives the toothed plate to move, the toothed plate drives the gear to rotate during the movement, the gear drives the first threaded sleeve to rotate, the first threaded sleeve rotates during the rotation of the threaded plate to move up, the threaded plate drives the reagent plate to move up, the reagent plate drives the reagent tube to move up, which solves the problem that the device cannot quickly place and take out the reagent tube;

[0017] Step 2: When the reagent plate is moved upward, the reagent rack is driven to move upward, the reagent rack drives the rotating block to move upward, the rotating block drives the second threaded sleeve to move upward, and during the second threaded sleeve moving upward, the second threaded sleeve is set by the threaded rod, and the second threaded sleeve drives the square plate to rotate. The rotation of the square plate generates airflow, which solves the problem that when the device is placed at an extreme temperature, the temperature accumulation affects the sample inside the reagent tube;

[0018] Step 3: When the reagent tube is filled with water samples and placed inside the reagent plate, the reagent plate falls due to the gravity of the multiple reagent tubes, and the reagent plate drives the threaded plate to fall. After the threaded plate falls, it no longer squeezes the first airbag. The first round tube, the first square box, the activated carbon plate, the elastic tube, and the aspirator are set to solve the problem of dust contamination of the water sample during storage.

[0019] Step 4: As the threaded plate falls, it drives the second square box to fall, and the second square box drives the second airbag to fall. When the second airbag falls and contacts the bottom of the inner wall of the box, the second airbag will be squeezed. The problem of shaking of the reagent tube during the falling process is solved by setting the second round tube, condensation plate, connecting tube, and irregular bag cover.

[0020] The present invention has the following beneficial effects:

[0021] (1) According to the present invention, the staff operates the pull block to push it to both sides, the pull block drives the box door to move, the box door drives the sliding plate to move, the sliding plate drives the connecting block to move, the connecting block drives the toothed plate to move, the toothed plate drives the gear to rotate during the movement, the gear drives the first threaded sleeve to rotate, the first threaded sleeve rotates during the rotation of the threaded plate, the threaded plate drives the reagent plate to move up, the reagent plate drives the reagent tube to move up, which facilitates the staff to take and place the reagent tube for sampling and improves the work efficiency.

[0022] (2) In the present invention, during the process of the reagent plate moving up, the reagent rack is driven to move up, the reagent rack drives the rotating block to move up, the rotating block drives the second threaded sleeve to move up, during the process of the second threaded sleeve moving up, the second threaded sleeve is set by the threaded rod, the second threaded sleeve rotates, and the second threaded sleeve drives the square plate to rotate. The rotation of the square plate generates airflow, thereby stirring the internal airflow of the box body, preventing extreme temperature from being concentrated and accumulating for a long time, affecting the storage of samples inside the reagent tube, and enhancing the protection effect of the device.

[0023] (3) According to the present invention, when the reagent tube is filled with water sample and then placed inside the reagent plate, the reagent plate falls due to the gravity of the multiple reagent tubes, and the reagent plate drives the threaded plate to fall. After the threaded plate falls, it no longer squeezes the first airbag, and suction is generated inside the first airbag. The suction enters the first square box through the first circular tube, and then enters the elastic tube through the first square box. The suction enters the aspirator through the elastic tube, thereby collecting the dust scattered above the reagent tube. After the dust enters the first square box, it is filtered and adsorbed by the activated carbon plate, thereby enhancing the protection effect of the device on the sample inside the reagent tube. The airflow generated during the rotation of the square plate can also enhance the dust absorption effect of the aspirator, thereby improving the protection effect of the device.

[0024] (4) In the present invention, the threaded plate drives the second square box to fall as it falls, and the second square box drives the second airbag to fall as well. When the second airbag falls to contact the bottom of the inner wall of the box, the second airbag will be squeezed, and the airflow inside the second airbag will enter the interior of the second square box through the second circular tube. Under the influence of the condensation plate, the airflow is converted into cold airflow, which enters the interior of the irregular bag cover through the connecting tube. The cold airflow makes the irregular bag cover bulge, thereby enhancing the stability of the reagent tube during storage and preventing the reagent tube from shaking during movement. The cold airflow circulating inside the irregular bag cover affects the reagent tube and prevents it from being affected by overheated airflow, thereby enhancing the accuracy of water sample detection inside the reagent tube.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The rotation of the square plate 468 generates airflow, thereby stirring the internal airflow of the box body 1, preventing extreme temperature from being concentrated and accumulating for a long time, affecting the storage of samples inside the reagent tube 462, and enhancing the protection effect of the device.

[0050] When the reagent tube 462 is filled with water samples and placed in the reagent plate 457, the reagent plate 457 falls due to the gravity of the multiple reagent tubes 462, and the reagent plate 457 drives the threaded plate 456 to fall. After the threaded plate 456 falls, it no longer squeezes the first air bag 473, and suction is generated inside the first air bag 473.
