When the various indicators of the detected gas are within the standard, the third motor 56 drives the second threaded rod 57 to rotate, the second threaded rod 57 drives the second nut block 58 to move, and the second nut block 58 pulls the sealing plate 61 to move, thereby opening the air outlet 33. After the gas is discharged through the first circular hole 51, it enters the fifth pipe 20 and is finally discharged to the outside.

[0041] The method of using this embodiment is explained as follows: In the initial state, the sealing plate 61 contacts the outside of the air outlet 33 to seal the air outlet 33; the first fixed tube 50 and the first circular hole 51 outside the first rotating drum 49 correspond to each other; the second fixed tube 53 and the second circular hole 54 outside the second rotating drum 52 are staggered and staggered, so that the gas can only be discharged through the first circular hole 51; When the gas enters the detection shell 16 for detection, the sealing plate 61 blocks the outside of the air outlet 33, so that the gas in the detection shell 16 can be fully detected; When the detected gas indicators are within the standard, the third motor 56 drives the second threaded rod 57 to rotate, the second threaded rod 57 drives the second nut block 58 to move, and the second nut block 58 pulls the sealing plate 61 to move, thereby opening the air outlet 33, and the gas is discharged through the first circular hole 51, enters the fifth pipe 20, and is finally discharged to the outside; When various indicators of the detected gas exceed the standard, the second motor 39 drives the first threaded rod 40 to rotate, the first threaded rod 40 drives the first nut block 41 to move (the first nut block 41 moves toward the direction of the second motor 39), the first nut block 41 drives the slider 37 and the synchronous plate 42 to move, the slider 37 drives the first rack 38 to slide, and the first rack 38 drives the first gear 46 and the second gear 48 to rotate a certain angle; The first gear 46 drives the first rotating drum 49 to rotate, and the second gear 48 drives the second rotating drum 52 to rotate. After the first rotating drum 49 rotates, the first rotating drum 49 and the first circular hole 51 outside the first fixed tube 50 are staggered with each other, and at the same time, the second rotating drum 52 and the second circular hole 54 outside the second fixed tube 53 correspond to each other; At the same time, when the synchronous plate 42 moves, it will also synchronously drive the pulling plate 60 and the sealing plate 61 to move. After the sealing plate 61 moves, the air outlet 33 is opened. If the opening range of the air outlet 33 is not large enough, the second motor 39 can be started to make the sealing plate 61 continue to slide, so as to open the air outlet 33 further. Subsequently, the gas exceeding the standard enters the sixth pipe 22 through the second circular hole 54 , is output to the seventh pipe 23 through the second suction fan 21 , and is finally filtered through the filter box 24 before being discharged through the eighth pipe 25 .

When the synchronous plate 42 slides, the rotating rod 74 will resist the toggle frame 66, thereby driving the toggle frame 66 to rotate, the outside of the synchronous plate 42 is fixedly connected to the limiting column 67, the outside of the pin shaft 69 is sleeved with a torsion spring 70, the torsion spring 70 plays a torsion reset role, and the limiting column 67 plays a limiting role on the toggle frame 66, in addition, the outside of the toggle frame 66 is fixedly connected to the extrusion plate 72, the outside of the synchronous plate 42 is fixedly connected to the mounting plate 71, the outside of the mounting plate 71 is fixedly connected to the pressure sensor 73, the outside of the seventh pipeline 23 is fixedly connected to the indicator light 85, and the pressure sensor 73 and the indicator light 85 are both electrically coupled to the control module.

[0043] The method of using this embodiment is explained as follows: When various indicators of the detected gas exceed the standard, the second motor 39 is started, and after the synchronous plate 42 slides (see the explanation in Example 3 for details), the rotating rod 74 will abut against the outside of the toggle frame 66. After the toggle frame 66 is abutted by the rotating rod 74, it will rotate through the pin 69, and the toggle frame 66 will drive the extrusion plate 72 to abut against the outside of the pressure sensor 73. After the control module receives the pressure signal, it will turn on the indicator light 85 to remind, indicating that the gas is filtered through the filter box 24. At the same time, it also feeds back to the control module, indicating that the first rack 38 has moved into place and the first motor 10 is turned off. Embodiment five:
