The invention is applicable to the field of PM2.5 sensing and monitoring, and provides a packaging device for packaging a laser PM2.5 sensor. The device includes: a shell, the top of the shell is provided with an opening for placing the sensor, and the sensor is The bottom surface fits the bottom surface of the casing. There is an annular air duct for air flow between the side of the sensor and the side of the casing. The air inlet and outlet of the sensor are both located on the annular air duct. The casing is directly above the air inlet. A transverse baffle is provided on the side wall, and the length of the transverse baffle is smaller than the lateral width of the annular air duct. A closed air outlet channel is provided at the air outlet of the annular channel, and the bottom of the air outlet channel is connected with the air outlet; the end cover, Located on the top of the casing, there are air inlets and air outlets on both sides of the end cover. The air inlet is connected to the air duct where the air inlet is located. The air outlet is connected to the top of the air outlet channel. The inner surface of the top of the end cover is provided with There are grooves; it assists the laser PM2.5 sensor to stably and accurately detect the mid-PM2.5 value of the gas to be measured.
Description
Technical field [0001] The invention belongs to the field of PM2.5 monitoring and sensing, and particularly relates to a packaging device and an automobile. Background technique [0002] In recent years, haze weather has frequently occurred in my country, and air quality issues have attracted great attention from the whole society. With the continuous improvement of people’s health awareness, air quality monitoring and air purification products have received extensive attention. In terms of exposure, vehicle PM2.5 particle detection equipment has become the focus of attention after household PM2.5 detection equipment. [0003] At present, the detection methods of the core sensor of the vehicle-mounted PM2.5 particle detection equipment are mainly divided into two types: infrared detection and laser detection. The laser detection is more accurate. The shells set outside the existing laser PM2.5 sensor are only used for The packaged parts do not assist the detection effect of the las...
