Described centrifugal wind wheel 3 profile substantially turriform or cry trapezoidal, its upper end is the second end plate 33, for only band central shaft hole nonventilated cecum, second end plate 33 be fixedly installed on central shaft hole install in order to wind wheel, wind wheel shaft sleeve that vertical precision is high, to overlap distribution arbor in order to install described centrifugal wind wheel 3；Second end plate 33 neighboring area is in order to one end of fixing centrifugation blade 32.Described centrifugal wind wheel 3 lower end is the second end plate 31, and the second end plate 31 central part is wind wheel air draught air inlet, and border area is wind wheel end ring plate, in order to the other end of fixing centrifugation blade 32；Described centrifugation blade 32 is arranged between second end plate the 31, first end plate 33, central axis relative to centrifugal wind wheel 3, radially circumference uniform distribution, quantity is odd number, and this centrifugation blade 32, it is tilting relative to the central axis of centrifugal wind wheel 3, it is according to the windward side of centrifugal wind wheel 3 direction of rotation, and for convex, crest curve increases with radial direction radius, it is typically designed and opens in for involute, to reduce wind wheel rotation wind cutting noise to greatest extent.
The structure of centrifugal wind wheel 3 arranges and makes it rotate when the direction of rotation specified with windward side, can be centrifuged from tilting centrifugation blade 32 throw away by air from the air inlet inspiration of the second end plate 31.Because the tilting of centrifugation blade 32 and fan blade windward side are involute convex surface, make thrown away whizzer motion vector direction, do not only have the radial level component of the hollow cavity pointing to housing, also there is the axially vertical component pointing to the second i.e. outlet air end of end plate 33, therefore, the air-out direction of centrifugation blade 32, for tilting upward centrifugal throwing away, is compared traditional horizontal centrifugal and is thrown away, and its suction is bigger.
One prominent and significant Technology design is, one specific wind-guiding component 2 is set between described centrifugal wind wheel 3 and housing, described wind-guiding component 2 its be shaped as guide cylinder, its outer wall is tightly linked with housing, the cylinder medial wall 21 of ventilating duct be on centrifugal wind wheel 3 radial circumference along centrifugal wind wheel 3 direction of rotation be involute open, centrifugal wind wheel 3 axially on helically rise until exhaust outlet the component that suits mutually with inner walls.
The first gap formed between described wind-guiding component 2 and described centrifugation blade 32 is: be that involute opens along centrifugal wind wheel 3 direction of rotation on centrifugal wind wheel 3 radial circumference, because of the turriform shape of centrifugal wind wheel 3 on centrifugal wind wheel 3 axis, the first gap constantly increases from the second end plate 31 to the second end plate 33 direction of centrifugal wind wheel 3.
Extension as described wind-guiding component 2 designs application, it is considered to the first gap can be made up of side by side different compression clearances, and wind-guiding inclined-plane 22 also can be made up of a plurality of involute step, to form evolvent type step air channel, can be described as compound air duct component.
Second housing 1 and wind-guiding component 2 can be one-body molded, it is also possible to molding respectively.
For making the gas through air channel pressurization not be short-circuited to inlet scoop, described second end plate 31 can be made into curved, keeps minimal moving clearance laminating with the air intake cervical region with the second tubular shell 1.
Described centrifugal wind wheel 3 is also called turriform centrifugal wind wheel.
As shown in figs. 14-15, as an embodiment of the present utility model, give the another embodiment of wind-guiding component 2 in this embodiment, described wind-guiding component 2 is ventilating duct, described centrifugal wind wheel 3 is arranged in described ventilating duct, and the cylinder medial wall 21 of described ventilating duct is provided with down the wind-guiding inclined-plane 22 of little big horn shape.This wind-guiding inclined-plane 22 can be one-body molded with cylinder medial wall 21, and certainly, this wind-guiding inclined-plane 22 can also be single two parts with cylinder medial wall 21.
In addition to motor 6 and centrifugal wind wheel 3, remaining part can be made up of metal or non-metallic plastic.By the special air channel air gap formed between described wind-guiding component 2 and centrifugal wind wheel 3, the centrifugal radial component motive air thrown away of centrifugal wind wheel 3 can be made, it not to be press directly against inner walls, form static pressure, gas is pressed to exhaust outlet output by static pressure, but not lost-motion pressure head, after involute air channel is compressed, gradually axially extrude to exhaust outlet spiral.The axial component air that centrifugal wind wheel 3 rotary compression goes out, then directly extrude from aerator exhaust outlet 41.Thus the two, significantly improve axial air draft ability, aerator pneumatic principle can obtain, and aerator input and output wind static pressure is constant, then export pneumatic pressure and increase, then input pneumatic pressure and also increase, show as aerator air draught ability and strengthen.
The entire outer diameter of described housing is about 240mm, and height is 180mm, and second housing the 1, first housing 4 is positioned by the installation screw of seam and docking and installs.The second built-in centrifugal wind wheel of housing 13, this centrifugal wind wheel 3 is arranged on the output shaft of motor 6, a diameter of 125mm of the second end plate 33, a diameter of 175mm of the second end plate 31, the center of the second end plate 31 is wind wheel inlet scoop, the a diameter of 120mm in wind wheel inlet scoop, this second end plate 31 can be made into curved, keeps minimal moving clearance laminating with the second housing 1 air intake cervical region；Centrifugation blade 32 is tilting, and the number of blade of centrifugation blade 32 is preferably 11, and centrifugation blade 32 curved surface of dashing forward windward is involute face.Between centrifugal wind wheel 3 and the second housing 1, it is equipped with wind-guiding component 2, this wind-guiding component 2 is the air channel component forming single compressed air gap road, its outer wall and the second housing 1 are integrally formed by injection, its internal chamber wall the second end plate 31 with centrifugal wind wheel 3 constitute compressed air passage initiate compression position gap be 4mm, highly it is equal to the axial height of centrifugal wind wheel 3, aerator radial circumference is that involute opens along wind wheel direction of rotation air channel element cavity wall, helically rise until aerator outlet air end suiting mutually with blower drum inwall on blower shaft upwards wind-guiding inclined-plane 22, centrifugal wind wheel 3 runs freely in wind-guiding component 2.
