Intelligent induction type ventilation equipment for laboratory

The invention discloses intelligent induction type ventilation equipment for a laboratory. The intelligent induction type ventilation equipment for the laboratory comprises an indoor fresh air pipeline and is characterized in that the inner side of the indoor fresh air pipeline is connected with an extension inner pipe in a sliding mode, a fresh air exhaust groove is formed in the bottom end of the extension inner pipe, an outer pipe fresh air exhaust groove is formed in the position, corresponding to the fresh air exhaust groove, of the bottom end of the indoor fresh air pipeline, one end ofthe indoor fresh air pipeline is connected with a filtering bent pipe, the tail end of the filtering bent pipe is connected with an L-shaped outer fresh air inlet pipe, an indoor mounting surface is mounted at the position, close to the filtering bent pipe, of the outer side of the indoor fresh air pipeline, and a vibration sensor is mounted on one side of the indoor mounting surface. According tothe intelligent induction type ventilation equipment for the laboratory, the problems that when ventilation equipment is used, ventilation equipment is difficult to extend or retract according to thesize of the laboratory, fresh air is difficult to obtain at the position far away from an exhaust outlet, the fresh air is inconvenient to exhaust to the indoor proper position, and the use effect ofventilation equipment is affected are avoided.
