Lampblack gas detection device with self cleaning function

Abstract

The invention relates to the technical field of lampblack detection, and in particular to a lampblack gas detection device with a self cleaning function. The lampblack gas detection device comprises amain box body; a rear end of the main box body communicates with a first gas guide tube and a second gas guide tube, which stretch into an exhaust passage and are used for collecting a gas to be analyzed, a lower end of the main box body communicates with a third gas guide tube and a fourth gas guide tube for exhausting the gas, a sliding plate driven by a driving component is slidably installedon the inner side of the main box body, the sliding plate is arranged in an L shaped, a first through hole and a second through hole are formed in a vertical end of the sliding plate, a third throughhole and a fourth through hole are formed in a horizontal end of the sliding plate, and a draught fan and a gas detector for lampblack detection are further installed on the inner side of the main boxbody. The lampblack gas detection device provided by the invention has a novel design, the sliding plate is driven by a disposed driving mechanism to move, so that separate connection of the first gas guide tube and the second gas guide tube with the third gas guide tube and the fourth gas guide tube is achieved, thereby achieving long-term collection and analysis of the gas.

Description

technical field [0001] The invention relates to the technical field of oil fume detection, in particular to a self-cleaning oil fume gas detection device. Background technique [0002] Kitchen fume contains more than 300 harmful substances, the most important lung cancer-causing substance is DNP, and the amount of DNP inhaled by housewives when preparing a meal in the kitchen is 188 times that in fresh air outside! What is even more shocking is that cooking on cookers with poor ventilation and extremely low combustion efficiency can cause health damage equivalent to smoking two packs of cigarettes a day! [0003] The exhaust of oily fume outside will cause air pollution. Therefore, when the oily fume is discharged, it is necessary to collect and analyze the oily fume gas first. The existing oily fume gas monitor generally needs to be manually hand-held for detection, which is inconvenient to use and cannot be measured at any time. [0004] Therefore, the present invention p...
