Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust detection technology, and in particular to a public health air dust detection device. Background Technology
[0002] Dust refers to solid particles suspended in the air. It is commonly referred to by many names, such as dust, grime, soot, mineral dust, sand, and powder, with no clear boundaries between these terms. The International Organization for Standardization (ISO) defines dust as solid suspended particles with a diameter of less than 75 μm. The presence of dust in the atmosphere is one of the main reasons for maintaining the Earth's temperature; too much or too little dust in the atmosphere will have catastrophic effects on the environment. However, in daily life and work, industrial dust is a major threat to human health and a leading cause of many diseases.
[0003] Currently, conventional dust detection devices typically detect dust in the air simultaneously, resulting in rather vague detection results and difficulty in distinguishing dust particles of different diameters. Furthermore, after prolonged use, dust accumulates inside the detection device, and failure to clean it promptly can lead to significant errors in subsequent detections.
[0004] Therefore, those skilled in the art have provided a public health air dust detection device to solve the problems mentioned in the background art. Utility Model Content
