[0045] Working principle: According to Figure 1-3As shown, the box cover 2 is rotated to open and expose the interior of the detection box 1. The box cover 2 is fitted on the support platform 3 for limiting, and then the support legs 11 are unfolded. The support legs 11 are rotated to unfold on the mounting seat 9, and the support legs 11 are rotated close to the limiting pieces 10 to support the support legs 11.

[0046] according to Figure 4-5 As shown, after the battery 7 is powered, it is installed. During installation, the battery 7 pushes the push plate 62 to push it into the limit buckle plate 6. Then, the battery 7 is pushed into the battery slot 8 to connect the electrical connection end 81 and the electrical output end 71 to conduct electricity. After the push plate 62 loses its limit, it is pushed back by the push spring 61 to position the push plate 62 to the side of the battery 7 to limit its installation. When the battery 7 is removed, the push plate 62 is pushed to release the limit between it and the battery 7.

[0047] according to Figure 7 As shown, when installing the collection bottle 17, limit it with the installation mechanism 18, place the collection bottle 17 between the two clamping pieces 186, push the slider 184 to support the collection bottle 17 through the limiting spring 185 to clamp and install it, then screw the bottle cap 171 and the collection bottle 17 together, install the connecting pipe 15 and the docking pipe 172, and complete the installation and fixation by magnetic attraction between the magnetic ring 16 and the installation ring 173.

After stopping, the one-way valve 176 works to prevent gas backflow. When conducting the test, take out the collection bottle 17, connect the outlet pipe 174 to the detection mechanism, open the outlet valve 175 to start the atmospheric monitoring work.
