Abstract

The invention discloses a multi-channel atmosphere sampling apparatus, wherein a gas path switching device comprises a connecting rod, a piston, a sleeve and a pushing mechanism; one end of the sleeve is sealed, and the other end of the sleeve is communicated with an external air source; an air nozzle which is communicated with the inside of the sleeve is arranged on the outer wall of the sleeve; a through groove is arranged by means of penetrating through a head face and a side face of the piston; the pushing mechanism is used for pushing the piston to slide in the sleeve through the connecting rod; an air exhaust passage is formed by the air nozzle, the through groove and the external air source when the air nozzle is aligned with the through groove; the gas path switching device further comprises a controlling device which is connected with the pushing mechanism, is used for controlling the position of the piston which is pushed by the pushing mechanism in the sleeve, and comprises an input module, a controller and a display module; the controller is connected with the input module and the display module respectively; the input module is used for inputting controlling parameters for the controller; and the controller is used for controlling the pushing mechanism to work depending on the controlling parameters. The multi-channel atmosphere sampling apparatus is simply structured and low in energy consumption.

Description

technical field

[0001] The invention relates to the field of atmospheric sampling devices, in particular to a multi-channel atmospheric sampling device with simple structure and low energy consumption. Background technique

[0002] With the process of human industrialization, environmental problems are becoming more and more serious. Industrial production emits a large amount of waste gas, and the content of harmful gases in the air continues to increase, which has brought serious harm to people's health.

[0003] Meteorologists and medical experts believe that hazy weather caused by fine particles is even more harmful to human health than sandstorms. Particles with a particle size of 10 microns or more will be kept out of the human nose; particles with a particle size between 2.5 microns and 10 microns can enter the upper respiratory tract, but some of them can be excreted through sputum, etc. The internal fluff blocks it, which is relatively less harmful to human health;...
