Be fixed with contiguous block on the described spiral case sidewall, contiguous block one end is fixed on the madial wall of casing.

Be fixed with demarcation strip in the described casing, make the interior spatial separation of casing become power house and exhaust chamber, spiral case is in power house, the air outlet tube of spiral case stretches out demarcation strip and communicates with exhaust chamber, three flow distribution plates that are fixed with in the exhaust chamber make exhaust chamber be formed with from top to bottom the first air vent, the second air vent and the 3rd air vent, simultaneously, three flow distribution plates are divided into upper exhaust outlet with the exhaust outlet of air outlet tube, middle exhaust outlet and lower exhaust outlet, upper exhaust outlet, middle exhaust outlet and lower exhaust outlet successively with the first air vent, the second air vent and the 3rd air vent communicate, the first air vent, the second air vent and the 3rd air vent are communicated with the nozzle of three universal balls down certainly successively by upper.

The beneficial effects of the utility model are:

1, it is compared with the used large-scale ventilator of basement of prior art, can save a large amount of ventilation ducts, saved piping cost, can suitably reduce simultaneously the height of basement, because the large-scale ventilator of the existing basement of volume ratio of the present utility model is much smaller, takes up room and want much less.

2, its casing is provided with controller, pop one's head in to detect the outer environment of blower fan by the smoke sensing of controller, to detect to such an extent that the smoke condition of external environment converts induced signal to and sends master chip in the controller to, master chip is according to the unlatching of this actuated signal control external rotor electric machine and stop, it need not manually, intelligence is convenient, and is very safe.

3, it is divided into three exhaust outlets with the exhaust outlet of spiral case, and communicates with the nozzle of three universal balls successively, and such three nozzle exhausts are even, improves using effect.

4, be fixed with zinc-plated porous slab 7 on its casing 3 inwalls, be provided with noise reduction glass wool 8 between casing 3 inwalls and the zinc-plated porous slab 7, can reduce the noise of blower fan.
