Further, smoke extractor of the present utility model, described actuating device is motor.

By such scheme, this utility model at least has the advantage that smoke extractor of the present utility model, Its body is fixedly installed on the top of the discharge flue of ceiling by connecting plate, passes through actuating device in body Connecting and have exhaust fan, the lower section of connecting plate is provided with outer smoke exhaust pipe, intermediate row smoke pipe, interior smoke exhaust pipe, outer row Smoke pipe is fixedly installed on connecting plate, and intermediate row smoke pipe is slidably disposed in outer smoke exhaust pipe, interior smoke exhaust pipe It is arranged in intermediate row smoke pipe, in ceiling, is provided with control device and cylinder.Time specifically used, work as generation During fire, fire-control center sends a signal to control device, and control device sends a signal to cylinder to be made to bring about the desired sensation The lever of cylinder inwardly stretches, and interior smoke exhaust pipe falls downwards, and drive intermediate row smoke pipe to Under fall, intermediate row smoke pipe is fixed on the bottom of outer smoke exhaust pipe by the first limited block and the second limited block, interior Smoke exhaust pipe is fixed on the bottom of intermediate row smoke pipe by the 3rd limited block, the 4th limited block, then controls device Opening exhaust fan, owing to the bottom of interior smoke exhaust pipe is near bottom surface, smoke extractor the most of the present utility model can It is effectively discharged out subaerial smog, thus reduces the injures and deaths of personnel, and due to outer smoke exhaust pipe, interior row Smoke pipe, intermediate row smoke pipe are made up of metal material respectively, therefore, also will not be burned even if burning, still So can normally discharge fume.

Described above is only the general introduction of technical solutions of the utility model, in order to it is new to better understand this practicality The technological means of type, and can be practiced according to the content of description, below with preferable reality of the present utility model After executing example and coordinating accompanying drawing to describe in detail such as.

Accompanying drawing explanation

Fig. 1 is the structural representation of smoke extractor of the present utility model；

Fig. 2 is the use state diagram of smoke extractor.

Detailed description of the invention

Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail. Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.

See Fig. 1 to Fig. 2, a kind of smoke extractor of this utility model one preferred embodiment, including body 1, The bottom of body is fixedly installed on the top of ceiling 2, and the bottom surface of body is provided with connecting plate 3, connecting plate It is fixedly installed on the upper surface of ceiling, connecting plate is fixedly installed actuating device 4, actuating device defeated Shaft through connecting plate and is connected with exhaust fan 5, and connecting plate is provided with multiple air vent (not shown), Offering discharge flue 6 on ceiling, discharge flue communicates with the inner chamber of body, fixing on the bottom surface of connecting plate Being provided with outer smoke exhaust pipe 7, the top of outer smoke exhaust pipe is fixedly installed on connecting plate, on the medial surface of outer smoke exhaust pipe Being provided with the first limited block 8, be provided with intermediate row smoke pipe 9 in outer smoke exhaust pipe, intermediate row smoke pipe sets slidably Put outside in smoke exhaust pipe, and on the lateral surface of intermediate row smoke pipe, be provided with the second limited block 10, middle smoke evacuation It is provided with the 3rd limited block 11 on the medial surface of pipe, in intermediate row smoke pipe, is provided with interior smoke exhaust pipe 12, interior smoke evacuation The top of the lateral surface of pipe is provided with fourth limited block 13 adaptive with the 3rd limited block, the outside of interior smoke exhaust pipe The bottom in face is provided with the 5th limited block 14, and the upper side of the 5th limited block can be with the first limited block or arrange outward The bottom surface contact of smoke pipe, is provided with cylinder 15 and controls device 16 in ceiling, control device and actuating device, Cylinder electrically connects, and the lever of cylinder protrudes in discharge flue and contacts with the bottom surface of the 4th limited block, outer row Smoke pipe, intermediate row smoke pipe, interior smoke exhaust pipe is made up of metal material respectively.
