The shoulder strap 7 can then be installed on the top of the body 2. The device can be conveniently carried by carrying it on your back, while freeing your hands to perform other tasks.

[0027] An outer frame 16 is fixed to the top right side of the front of the body 2, and a viewing plate 18 is provided at the front of the outer frame 16. Mounting feet 14 are fixed at the four corners of the front of the outer frame 16, and knobs 17 are provided at the four corners of the front of the viewing plate 18. The knobs 17 have external threads on the outside, and the rear end of the knobs 17 passes through the interior of the viewing plate 18 and is threadedly connected to the mounting feet 14.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, a viewing panel 18 is installed and fixed on the front of the display screen 15 using four sets of knobs 17. The viewing panel 18 can be used to cover the outer side of the front of the display screen 15 to prevent scratches and wear. At the same time, the viewing panel 18, which is made of transparent acrylic material, will not affect the display of the display screen 15.

[0029] A side cover 3 is provided on the left side of the body 2, and a side cover 8 is provided on the right side of the body 2. A slot 20 is provided on the inside of the left side of the side cover 3 and the inside of the right side of the side cover 8. Fixing bolts 11 are provided at the four corners on the left side of the side cover 3 and the four corners on the right side of the side cover 8. A reserved hole 12 is provided at the inside of the four corners on both sides of the body 2. The slot 20 passes through the inside of the side cover 3 and the side cover 8 respectively. The fixing bolts 11 pass through the inside of the side cover 3 and the side cover 8 respectively and are threadedly connected to the reserved hole 12.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, side covers 3 and 8 are installed and fixed on both sides of the outside of the body 2, which can cover the outer corner of the device and facilitate the external impact protection of the device.

[0031] The four corners of the bottom of the body 2 are fixed with feet 1 respectively. The left side of the body 2 is equipped with a collection port 4.

[0032] Working Principle: In use, the external power supply is connected to the power interface 10. After powering on the device and setting the parameters, dust-laden air can be collected via the acquisition port 4. The gas being measured enters the internal measuring cavity of the body 2, where the laser beam is collimated to form a stable spot. Dust particles passing through the laser beam induce Mie scattering, which is captured by a high-sensitivity photodiode array. The signal is amplified and filtered before being converted into a digital signal. The microprocessor inside the body 2 calculates the dust mass concentration using an algorithm model and displays it in real-time on the display screen 15.

[0033] Simultaneously, when the environmental monitoring device needs to be carried, the two sets of hanging loops 22 on the shoulder strap 7, which are fixed to the top of the body 2 respectively, can be locked and installed on the top of the body 2. The shoulder strap 7 allows for convenient carrying of the device, freeing up the hands for other tasks. Furthermore, during the use of the display screen 15, a viewing panel 18 is fixed to the front of the display screen 15 using four sets of knobs 17. The viewing panel 18 provides auxiliary protection against scratches and abrasions by covering the outer side of the front of the display screen 15. The transparent acrylic material of the viewing panel 18 does not affect the display of the display screen 15. Additionally, during the use of the monitoring device, side covers 3 and 8 are fixed to the outer sides of the body 2 respectively, providing external protection against impacts.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
