1121 flow forward of natural air inlet mouth is mixed with recuperated gas.
The ratio between outlet air open area and air-admitting surface of front side air dam 1411 are smaller than the outlet air of rear side air dam 1412
The ratio between open area and air-admitting surface, so that the flow velocity of the air-flow blown out by front side round wind outlet is greater than by rear side annular air outlet
The flow velocity of the air-flow of mouthful blowout, and then the air-flow that is blown out by front side round wind outlet is improved to being blown out by rear side round wind outlet
The guiding function of air-flow improves the air supplying distance of annular air guide member 141.
The air-admitting surface of front side air dam 1411 is smaller than the air-admitting surface of rear side air dam 1412, so that front side is led
The air output in wind portion 1411 is less than the air output of rear side air dam 1412, and then send annular air guide member 141 with farther away
Wind apart from while, have biggish air output.The area of rear side round wind outlet can be increased as much as possible, to reduce wind
Resistance, keeps the flowing of air-flow more smooth.
Multiple axis along axis of imaginaries can be equably provided at front side round wind outlet and rear side round wind outlet respectively
The flow deflector 1414 extended to direction and radial direction, is blown out with reduction by front side round wind outlet and rear side round wind outlet
The shifting amount of air-flow in radial directions, and then make the air-flow blown out by front side round wind outlet and rear side round wind outlet more
Uniformly.
The rear wall of the airflow channel of front side air dam 1411 can be used as the antetheca of the airflow channel of rear side air dam 1412, no
Production cost can be only reduced, the air-flow flowing changing rule in front side air dam 1411 and rear side air dam 1412 can also be made
Unanimously, it reduces from front side round wind outlet and is altered due to interfering with each other to radial direction from the air-flow that rear side round wind outlet is blown out
Dynamic shifting amount enhances the whole air-out effect of annular air guide member 141.Wherein, the backward side wall of front side air dam 1411 can
It is set as arching upward backward, by the water conservancy diversion forward of the recuperated gas in rear side air dam 1412.
