Abstract

The invention is suitable for the field of sensing and monitoring, and provides a laser PM2.5 sensor packaging device and a car. The device includes: a casing, with an opening on the top of the casing for placing the laser PM2.5 sensor. The side of the sensor is in contact with the There is an annular air duct between the sides of the housing that allows air flow to pass through. The air inlet and outlet of the sensor are located on the annular air duct. There is a transverse baffle on the side wall of the housing directly above the air inlet. The transverse baffle The length is less than the lateral width of the annular air duct; the end cover is arranged on the top of the casing. There are ventilation holes on both sides of the top of the end cover. The two ventilation holes are connected to the annular air duct. The inner surface of the top of the end cover is provided with a groove. , a fixed sponge is placed between the end cover groove and the sensor. The end cover squeezes the sensor through the fixed sponge. If the air flow in the environment changes sharply, the inlet air flows through the buffer of the annular channel and the flow restriction of the baffle. This prevents the air intake volume from the air inlet from fluctuating significantly, which is beneficial to the stability of the sensor detection performance.

Description

technical field [0001] The invention belongs to the field of PM2.5 monitoring and sensing, and in particular relates to a laser PM2.5 sensor packaging device and an automobile. Background technique [0002] In recent years, smog has occurred frequently in our country, and the air quality problem has 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. Contact degree, PM2.5 particle detection equipment for vehicles 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. Packaged parts do not play an auxiliary role in the detection effect of the laser PM2.5 sensor. Contents of the invention [0004] An embodiment of ...
