Problems solved by technology

However, there is no equipment to detect the concentration of PM2.5 in the air inside and outside the car. Users can only choose the internal circulation or external circulation mode according to their own judgment. This method is very inaccurate

Embodiment Construction

[0019] like Figure 1 to Figure 6 As shown, a PM2.5 detection module according to the present invention is used to detect the air PM2.5 concentration inside / outside the car on a car. The PM2.5 detection module includes a PM2.5 sensor 1 , an outside air sampling tube 2 , an inside air sampling tube 3 , a first fan 4 and a second fan 5 . One end of the air sampling pipe 2 outside the car extends out of the car cockpit, and the other end is connected to the first fan 4 , and the air outlet of the first fan 4 communicates with the sampling port 11 of the PM2.5 sensor 1 . One end of the air sampling pipe 3 in the car is stretched out in the cockpit of the car, and the other end is connected to the second fan 5 , and the air outlet of the second fan 5 communicates with the sampling port 11 of the PM2.5 sensor 1 . The first fan 4 , the second fan 5 and the PM2.5 sensor 1 are respectively connected to a control unit (not shown) in the vehicle, and the control unit can control the fir...

Abstract

The invention relates to a PM2.5 detection module. The PM2.5 detection module comprises a PM2.5 sensor, an external air sampling tube, an in-car air sampling tube, a first fan and a second fan, wherein one end of the external air sampling tube stretches out of an automobile cab, and the other end of the external air sampling tube is connected onto the first fan; an air outlet of the first fan is communicated with a sampling opening of the PM2.5 sensor; one end of the in-car air sampling tube stretches out of the automobile cab while the other end of the in-car air sampling tube is connected onto the second fan, and an air outlet of the second fan is communicated with the sampling opening of the PM2.5 sensor; and the PM2.5 sensor can detect the PM2.5 concentration of air sucked in the first fan / the second fan. Air inside and outside the automobile cab can be sampled and conveyed to the PM2.5 sensor to be detected by the first fan and the second fan, and only one PM2.5 sensor can realize real-time detection on the PM2.5 concentration of the air inside and outside the automobile cab.

Description

technical field [0001] The invention relates to a PM2.5 detection device. Background technique [0002] With the continuous increase of car ownership and people's attention to the environment, the air detection and purification related to cars has attracted more and more attention. In the existing air environment, PM2.5 concentration is a very important air quality index. At present, the detection of PM2.5 concentration is mainly aimed at the static air environment, such as indoors, inside the car, etc., and has not yet been tested for the flowing air environment. [0003] In the use of automobiles, in order to enable drivers or passengers to obtain a better air environment, the air conditioner in the automobile has an internal circulation mode for circulating the air inside the vehicle and an external circulation mode for communicating with the air outside the vehicle. When the air environment outside the car is poor, the air conditioner in the car can switch to the inter...
