Portable personal environment monitoring and purifying system

Abstract

The invention discloses a portable personal environment monitoring and purifying system. The system comprises a shell provided with an intake port and an exhaust port in the top and the bottom; an activated carbon filter screen, an intake port fan, a negative ion generator, an electrostatic absorption filter screen and an exhaust port fan are arranged in the shell in sequence from bottom to top; the negative ion generator includes multiple discharge devices arranged in sequence from bottom to top; the discharge devices include multiple discharge tip ends; the discharge devices are connected with single-chips through negative ion generation circuits; and the single-chips are respectively connected with the intake port fan, the exhaust port fan and a power supply. The system can monitor the environmental PM2.5 concentration value in real time; after a start button is opened, the intake port fan, the negative ion generator and the exhaust port fan start to work to generate negative ions helpful for human bodies and to send the negative ions to the exhaust port; and the system is low in power consumption and convenient to personally carry.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, in particular to a portable personal environmental monitoring and purification system. Background technique [0002] PM2.5 (fine particulate matter) refers to particulate matter in the ambient air with an aerodynamic equivalent diameter of ≤2.5 microns. It can be suspended in the air for a long time, and the higher its concentration in the air, the more serious the air pollution. Although PM2.5 is only a small component of the earth's atmospheric composition, it has an important impact on air quality and visibility. Compared with coarser atmospheric particles, PM2.5 has a small particle size, large area, strong activity, and is easy to attach toxic and harmful substances (such as heavy metals, microorganisms, etc.), and has a long residence time in the atmosphere and a long transportation distance. Therefore, it has a greater impact on human health and atmospheric environmental...

And when the ozone content reaches more than 0.5ppm, it will have adverse effects on the human body.

Therefore, although the air purifier can provide a certain purification of indoor air, its disadvantages are also obvious. It is easy to generate ozone that is harmful to the human body, high cost, and high power consumption. It is only suitable for indoor use and is bulky and difficult to move.
