Preferably, described exhaust outlet is square.
Preferably, described louvre blade is plastic material.
Preferably, described electromagnetic core is cylindrical soft iron.
Preferably, described electromagnetic core and described iron plate are coated in a safety cover.
As mentioned above, the utlity model has following beneficial effect: utilize slidable bar is set on louvre blade, and attract described slidable bar by electromagnetic core as traction source, and then drive described louvre blade to launch, whole louvre blade launches action and all after fan starting energising, is completed by electromagnetic core, and without being started by the wind-force producing after fan starting, thereby reduce the energy consumption of blower fan, simultaneously if energising in the situation that blower fan can keep the state launching, relatively of the prior artly carry out driving situation by wind-force and come more stablely; After blower fan stops or after power-off, louvre blade naturally droops the state of getting back to Natural closure under the tension force impact of spring.To sum up, in the relative prior art of the utility model, drive the structure of louvre blade to come more stablely and effectively reduced the energy consumption of motor by wind-force.
