Single-channel air quality detection device

Abstract

The invention discloses a single-channel air quality detection device, and particularly relates to the field of air quality detection equipment. The single-channel air quality detection device comprises a shell, a horn mouth, a light sensor and a laser module, a horn mouth mounting column is integrally formed on the side surface of the shell, a channel cover plate limiting plate is integrally formed on the bottom surface of the shell, and an air outlet is formed in the left side of the shell. A display device installation groove is formed in the front face of the shell, a charging port is fixedly formed in the front face of the shell, a battery installation groove is integrally formed in the bottom face of the shell, and the outer surface of the horn mouth installation column and the inner cavity of the horn mouth are fixedly installed. By arranging a baffle with a certain height on the outer side of the channel cover plate limiting plate, it is avoided that when the equipment works, dust in air falls into the equipment from a gap between the channel cover plate and the shell, dust is accumulated in the equipment, equipment detection is inaccurate, and the practicability of the equipment is improved.

Description

technical field [0001] The invention relates to the technical field of air quality detection equipment, more specifically, the invention is a single-channel air quality detection device. Background technique [0002] With the development and progress of science and technology, people's daily life, production and other activities will produce air pollution. Air pollution will not only affect people's health, but also interfere with people's daily life. Therefore, the detection of air quality is very important. Air quality testing focuses on the detection of dust in the air. [0003] At present, the air quality detection devices on the market pass air into the interior of the air quality monitoring device, and then measure the content of PM2.5 in the air through the internal laser module and light sensor, and then input the detection results to the central The processor performs data processing, and then sends it to the display device for data display. However, during use, it...

[0003] At present, the air quality detection devices on the market pass air into the interior of the air quality monitoring device, and then measure the content of PM2.5 in the air through the internal laser module and light sensor, and then input the detection results to the central The processor performs data processing, and then sends it to the display device for data display. However, during use, it is found that a large amount of dust will accumulate in the air channel during use, which will cause inaccurate detection results of the equipment. The air channels of the quality inspection device are all integrally formed, and there are a lot of dead angles inside, so it will be extremely difficult to clean
