Problems solved by technology
In order to have accurate measurement, each reflector 231 of the reflector 2 needs to be kept clean, but because the reflector 2 is used in a high air pollution area, the mirror 232 of each reflector 231 is easily contaminated. Dust, or highly corrosive gases such as strong acid and strong alkali commonly used in industry, make the coating of the reflector 231 easy to peel off, and Taiwan, China is a rainy island climate with high environmental humidity, so the reflector 231 It is also easy to have water vapor on the surface, and the above all cause the surface of the reflector 231 to be dirty and easily corroded to affect the reflection effect. Therefore, the service life of the reflector 231 is short, and the replacement frequency is high, which increases the cost of expenditure.

The invention provides an optical path measuration reflection unit for environmental monitoring. The optical path measuration reflection unit comprises a substrate, a reflector element arranged on the substrate, an air supply unit arranged on the substrate, and a heating unit arranged on the substrate, wherein the air supply unit blows towards the direction of the reflector element, the heating unit is arranged on the substrate and positioned between the reflector element and the air supply unit, and can enable wind blown by the air supply unit to be heated by the heating unit and then return to the reflector element. Through air blowing of the air supply unit towards the reflector element, shielding of air flow is formed, so that dust is prevented from attaching to the reflector element, the heating unit enables temperature of the wind blown from the air supply unit to be increased, plays the role of evapotranspiration of steam, and greatly reduces the chance that the reflector element is polluted, so that the service life of the device is prolonged, and an accurate measurement result is maintained.
Description
technical field [0001] The invention relates to an environment monitoring device, in particular to an optical path measuring reflection device for environment monitoring. Background technique [0002] refer to figure 1 and figure 2 , is an existing Fourier transform infrared spectrometer 1 (FTIR) for detecting air quality, comprising a transmitter 11 emitting infrared light, and a reflector 2 for reflecting infrared light, and the reflector 2 includes a housing 21 , an outer cover 22 disposed on the housing 21 , and a reflection unit 23 disposed in the housing 21 . Wherein, the outer cover 22 has an opening 222 through which the reflective unit 23 communicates with the outside world. The reflective unit 23 has a plurality of reflective elements 231 arranged against each other, and each reflective element 231 includes three mirrors 232 perpendicular to each other. [0003] After the infrared light is emitted by the emitter 11, after passing through the opening 222 of the ...
