New description: [New technical field] The present invention relates to an environmental monitoring device, in particular to an optical path measuring and reflecting device for environmental monitoring. [Prior Art] Referring to Figures 1 and 2, A conventional Fourier transform infrared spectrometer (UFTIR) for detecting air quality includes an emitter 11 that emits infrared light, and a reflector 2 for reflecting infrared light. The reflector 2 includes a casing and a An outer cover 22 on the housing 21 and a reflection unit 23 disposed in the housing of the housing. The outer cover 22 has an opening 222 for communicating the reflection unit 23 with the outside. The reflection unit 23 has a plurality of The reflective members 231 are arranged, and each of the reflective members 231 includes three lenses 232 that are perpendicular to each other. After the infrared ray is emitted by the emitter ,, after the opening of the reflector 2: 222, the red ray is reflected back to the emitter u by the lens 232 of the reflector 231 of the reflector 2, and the infrared ray After the emission and reflection path, /, after the gas contact, the specific frequency of the infrared light will be absorbed by the gas, and the different gases will have different absorption frequencies, so the light reflected back to the emitter U will be specified. The energy at the frequency will be attenuated, so that "the specific frequency of attenuation, and the amount of attenuation energy, determine the type and concentration of the gas. Therefore, the above-mentioned Fourier transform infrared spectrometer 1 is often used in industrial areas 'large petrochemical plants, steel and steel, The perimeter of the airport's high-air sweat-dyeing area is used to monitor the air quality. It is expected to avoid toxic gases harmful to the human body, avoiding 3 M430602 poisonous gas, and affecting personnel safety. For accurate measurement, Each of the reflectors 231 of the reflector 2 needs to be kept clean, but since the reflector 2 is used in a high air pollution area, the lens of each of the reflectors 231 is easily contaminated. Dust and dirt, or high-corrosion gas such as strong acid and alkali, which are commonly used in industry, make the anti-(4)231 mineral film easy to fall, and Taiwan is a rainy island climate. The ambient humidity is high, so these reflectors The surface of the reflector 231 is filthy and susceptible to erosion and affects the reflection effect. Therefore, the reflector 231 has a short service life, a high frequency of replacement, and an increase in cost.

The reflecting unit includes a plurality of reflecting members arranged in an array, each reflecting member including three perpendicular to each other. a lens, each lens having a reflective surface plated with metal and used for reflection, and a reflecting surface of each of the reflecting members is opposite to each other. The direction of the blowing unit toward the reflecting unit The heating unit is disposed on the substrate and located between the reflecting unit and the air blowing unit, and the wind blown by the air blowing unit is heated by the heating unit to the reflecting unit. The function of the novel is: by the air supply The unit blows air toward the reflecting unit to form a shield for the airflow 'to prevent dust from adhering to the reflecting members, and the heating unit increases the temperature of the air blown by the air blowing unit, and has the function of evaporating the water vapor 4 M430602, so that , greatly reducing the chance of such reflective parts being infected by sweat, increasing the service life and maintaining accurate measurement results.

In the present embodiment, the reflective unit 6 is for reflecting infrared light, and The lens 611 of the reflecting unit 6 can be made of glass or stainless steel, and the metal plated on each of the reflecting members 61 can be gold, silver, or a layer of mineral silver and then a layer of gold. Referring to FIG. 3, the air blowing unit 7 blows air toward the reflecting unit 6, and the air blowing unit 7 includes a blower 71. The air blower 71 has an air outlet 711 facing the reflecting unit 6. The heating unit 8 is disposed at the air blowing unit The substrate 5 is located between the reflection unit 6 and the air supply unit 7, and the heating unit 8 includes a plurality of heating sheets 8丨 electrically connected to the external power source and spaced apart, and the heating sheets 81 of each of the 5 M430602 heating sheets are formed by the air supply. A gap 811 in which the unit 7 extends toward the reflecting unit 6. The I sensing member 91 is electrically connected to the heating unit 8 and senses the ambient humidity, and the sensing member 91 senses that the ambient humidity is greater than - the set humidity automatically activates the heating unit 8. The control switch 92 is electrically connected to the heating unit 8, and the heating unit 8 can be manually used. In this embodiment, the set humidity is 85% of humidity, but can be adjusted according to the needs of use. / Figure 5, using a transmitting device 32 to emit infrared light to the optical path measuring and reflecting device 31, the infrared light is reflected back to the transmitting device 32' via the reflecting member 61 of the reflecting unit 6 The infrared ray analyzes the specific frequency that is absorbed, and further determines the type and concentration of gas between the emitting device 32 and the optical path measuring reflector 431. 3 and FIG. 5, the air blower 71 of the air blowing unit 7 continues to pass through the gap 811 of the heating unit 8 through the air gap 7 811 toward the reflecting unit 6 and a wind shield is formed in front of the reflecting unit 6.
