Device for detecting automobile internal and external air quality

Abstract

The invention relates to a device for detecting automobile internal and external air quality. The device comprises a dust box pedestal and a dust box cover which can be mutually fastened to form a boxbody. A tube-shaped air flue chamber assembly is arranged in the dust box pedestal; two plastic hoses capable of respectively connecting inside and outside of a vehicle are arranged outside the dustbox pedestal; the other end of each plastic hose is provided with an acquisition head assembly; and a dust sensor clings to the tube-shaped air flue chamber assembly. Air enters the tube-shaped air flue chamber assembly through the acquisition head assemblies and the plastic hoses and then is detected through the dust sensor. The device has a simple structure, is ingeniously designed, and achievesgood reaction sensitivity and high accuracy of PM2.5 and PM10 values as well as higher detection precision.

Description

technical field [0001] The invention relates to the technical field of air detection, in particular to a device for detecting air quality inside and outside an automobile. Background technique [0002] In recent years, heavy industry has been vigorously developed in many parts of the world, resulting in a sharp drop in air quality and a serious threat to human health. Domestic people are paying more and more attention to the quality of the living environment, especially PM2.5 in the air, which has been received by all walks of life. With the attention of the industry, various industries have provided PM2.5-related detection and purification products. [0003] Automobile manufacturers are no exception, investing a lot of resources in research and development of products related to in-vehicle air quality management. . The common and practical dust sensors on the market now have the following defects: 1. The temperature range of the dust sensor is -10~60 degrees; 2. The detec...

AI Technical Summary

Problems solved by technology

The common and practical dust sensors on the market now have the following defects: 1. The temperature range of the dust sensor is -10~60 degrees; 2. The detection accuracy of the dust sensor can only be above 50ug±50%; 3. One sensor can only detect one 4. When the existing products are detected while driving, the data contrast is large, unstable or impossible to detect; 5. There is no waterproof and dustproof protection function; 6. There is no protection against large particles, mud, wool fabrics, etc. Preliminary filter system, the lens inside the sensor is easy to accumulate dust, the life is short, and the sensor needs to be replaced after 1000 hours
