Oil smoke detection device

Abstract

The invention discloses an oil smoke detection device. The oil smoke detection device comprises a sampling unit, a processing module, a light emitting module and a light receiving module, wherein thelight receiving module and the light emitting module are arranged on different sides of the sampling unit; the light receiving module comprises a sensing unit and a lens; the lens is arranged betweena detection cavity of the sampling unit and the sensing unit; the processing module is connected with the sensing unit; the light receiving module is used for receiving light scattered by oil smoke; and the sampling unit is arranged outside an oil smoke pipeline and communicates with the oil smoke pipeline. The oil smoke detection device has the substantial effects of improving the intensity of anoptical signal received by the light receiving module when working, reducing the interference of stray light, improving the detection accuracy, and having the characteristics of long service life andconvenient operation.

Description

technical field [0001] The invention relates to the field of detection of cooking smoke, in particular to a lampblack detection device. Background technique [0002] During the cooking and processing of food, the organic matter of oil and food is thermally decomposed or cracked, and the moisture in the food is rapidly vaporized. At the same time, the thermal decomposition of combustion produces fine particles and harmful gases, which eventually form volatiles and gases of oil and food at high temperature. Soot composed of sol, water vapor and fine particulate matter. Oil fume not only directly harms the health of the surrounding people, but also has become an important source of pollution in the urban atmosphere. The use of oil fume detectors to accurately detect catering oil fume is a necessary basic link for oil fume control. [0003] China Patent Authorization Announcement No. CN 205481203 U, the authorization announcement date is August 17, 2016, discloses a laser oil f...
