Embodiment Construction

[0024] Such as figure 1 As shown, a two-solenoid valve detecting a dual-solenoid valve detection vehicle inside and outside PM2.5 concentration, including an outer intake pipe 1, a vehicle intake pipe 2, 1 solenoid valve 3, a laser module 4, a fan 5, 2 Electromagnetic valve 6, car out of the air tube 7 and the vehicle out of the air pipe 8; the outer intake pipe 1 and the inner air intake pipe 2 separately connected to the first solenoid valve 3 air port, No. 1 solenoid valve 3 air outlet laser module 4 Inlet, fan 5 intake end laser module 4 out of the air, fan 5 extra gas end 2 Electromagnetic valve 6 intake port, No. 2 solenoid valve 6 venting port separately take the air outlet trachea 7 and the vehicle inner air pipe 8 . In order to improve the sealing, the system also includes sealing housing 9, 1 solenoid valve 3, the laser module 4, 2 solenoid valve 6, and the fan 5 are placed in the sealing housing 9. In order to further avoid interference between each structure, the pres...

Abstract

The invention discloses a system for detecting the PM2.5 concentration inside and outside the car with double solenoid valves, which includes the air intake pipe outside the car, the air intake pipe inside the car, the No. 1 solenoid valve, the laser module, the No. 2 solenoid valve, the air outlet pipe outside the car and the Air outlet pipe; the air intake pipe outside the vehicle and the air intake pipe inside the vehicle are respectively connected to the air inlet of the No. 1 solenoid valve, the air outlet of the No. 1 solenoid valve is connected to the air inlet of the laser module, and the air outlet of the laser module is connected to the air inlet of the No. 2 solenoid valve The air outlet of No. 2 solenoid valve is respectively connected to the air outlet pipe outside the vehicle and the air outlet pipe inside the vehicle. The invention is simple in structure, low in cost and easy to control. It can switch the air duct through the electromagnetic valve to detect the PM2.5 concentration inside and outside the car, and at the same time solve the problem of inability to collect gas due to the pressure difference inside and outside the car.

Description

Technical field [0001] The present invention belongs to the field of automotive air quality testing, and in particular, the present invention relates to a system of a dual-solenoid valve detection vehicle inside and outside the PM2.5 concentration. Background technique [0002] Air quality is the focus of global concern, especially in recent years with the rapid development of the industry, the damage caused by the air quality has also increased sharply, the PM2.5 is small, the area is large, the activity is strong, and it is easy to use toxic, harmful Substances (eg, heavy metals, microorganisms, etc.), and long residence time in the atmosphere, the transport distance is far, and thus the impact on human health and atmospheric environment is greater. [0003] PM2.5 concentration is an important indicator that measures the quality of air quality. The higher the concentration, the worse the quality of the air; the PM2.5 concentration detection equipment on the existing car is basi...
