Then, the wind shield 20 connected to the circumferential surface of the limit rod 19 is rotated to make the wind shield 20 separate from the covering of the bellows 6, so that the gas to be tested is sucked into the suction groove 7 through the suction force generated by the rotation of the blade 8, and then the gas to be tested enters the sensor group 13 through the ventilation pipe 9. The concentration of the harmful substance is converted into an electrical signal through the various detections of the sensor group 13, and then the circuit processing and data analysis are performed by the central processing system 15, and the sorted data is transmitted to the mobile device and the remote terminal, thereby realizing the detection of the harmful substance.

[0028] For details, please refer to Figure 2 The upper end of the support pad 3 is fixedly connected to two support rods 23, and the inner wall of one side of the placement groove 2 is fixedly connected to a rubber pad 11.

[0029] In this embodiment: the two support rods 23 fixedly connected to the upper end of the support pad 3 can support the bellows 6 in the working and static states to prevent the bellows 6 from tilting left and right, thereby preventing damage to the device and failure to operate normally. The rubber pad 11 fixedly connected to the inner wall of one side of the placement groove 2 can form a good buffering force between the components in the device to reduce mutual vibration and collision.

Both ends of the limit rod 19 are fixedly connected to limit blocks 21.

[0033] In this embodiment: by rotating the wind shield 20 connected to the circumferential surface of the limit rod 19, the air flow of the bellows 6 can be controlled, so that the external air will not directly enter the inside of the device when the device is not in use, thereby reducing the impact of dust on the device. By fixing the limit blocks 21 at both ends of the limit rod 19, the limit rod 19 can be limited to prevent the wind shield 20 from falling when the circumferential surface of the limit rod 19 rotates, thereby preventing the limit rod 19 from falling and being damaged.

[0035] When the device is needed, the mobile power supply 4 fixedly connected to the upper end of the support pad 3 is energized to the drive motor 5 to drive the blade 8 fixedly connected to the output end of the drive motor 5 to rotate and generate suction, and then the wind shield 20 sleeved on the circumferential surface of the limit rod 19 is moved, so that the gas to be tested is sucked into the suction groove 7 by the suction force generated by the rotation of the blade 8, and then enters the sensor group 13 through the suction groove 7. The concentration of the harmful substance is converted into an electrical signal through the various detections of the sensor group 13, and then the circuit processing and data analysis are performed by the central processing system 15, and the sorted data is transmitted to the mobile device and the remote terminal, thereby realizing the detection of the harmful substance.
