Description

Technical Field

[0001] The utility model belongs to the field of detection equipment, and in particular relates to a particle concentration detection device based on light scattering. Background Art

[0002] Light-scattering particle concentration detection devices utilize the phenomenon of light scattering to measure the concentration of particulate matter (such as dust, smoke, and pollen) in an environment. When light strikes particulate matter, it scatters. The device measures the scattered light's intensity, angle, and other characteristics to estimate the particle concentration. However, light-scattering particle concentration detection devices have certain drawbacks in signal transmission. During transmission, electrical signals are susceptible to interference, which can cause signal distortion and data deviation. This arises from the long transmission paths, resulting in insufficient interference resistance. Conventional solutions employ shielded cables, encasing the transmission paths in a metal shielding layer to prevent electromagnetic interference. However, shielded cables are expensive and increase the weight and volume of the cables, reducing portability for portable devices. Furthermore, over time, the shielding layer can become damaged, reducing shielding effectiveness. Therefore, a new structure is needed to address these technical issues. Utility Model Content
