Jet effect, realize that unit Bladeless is blown, be specially：
The utility model is passed through a small amount of compressed gas conduct by the use of the suction hole 14 of the interlude 13 in air channel 1 as nozzle
Power source, gas are sprayed at a high speed by suction hole 14, and because of Coanda effect, this strand of primary airstream is attached to the inner surface contour face in air channel 1
Upper flowing, cavity center in air channel 1 is produced a low-pressure area, and cause around substantial amounts of air be inhaled into, primary airstream and
Surrounding flow converges the rear wind outlet section 11 for just forming speed is higher, capacity is bigger air-flow in air channel 1 and exported again, finally realizes machine
Group Bladeless air-supply.
Above-mentioned Coanda effect is also known as attached wall effect or Coanda effect, and fluid, which has, leaves original flow direction, is changed to
The tendency flowed with the body surface of protrusion.
One preferably or in alternative embodiment, air channel 1 can be venturi conduit.Venturi is produced by venturi conduit
Effect：When air-flow blows over obstacle, the air pressure of near ports is relatively low above the lee face of obstacle, is inhaled so as to produce
It is attached to act on and cause the flowing of air.Using Venturi effect, accelerate fluid velocity, in air channel 1 fluid from the coarse to fine
Outlet rear side forms " vacuum " area, and suction-operated is produced using " vacuum " area.The entrance of wind inlet section 12 in air channel 1 is cut
Area A1 is more than the sectional area A2 that the wind inlet section 12 in air channel 1 exports, and the flow velocity V1 of the wind inlet section 12 in air channel 1 is less than going out for air channel 1
The flow velocity V2 of wind section 11, the hydrostatic pressure P1 in the wind inlet section 12 in air channel 1 are more than the hydrostatic pressure in the wind outlet section 11 in air channel 1
Power P2.
