Further, the height of described cam is not more than the height of described flabellum array.
Further, described shell divides the occlusion of upper and lower two parts to install, and described impeller unit is arranged on the middle of shell, and the wind guide tank of shell is installing the circular mounting hole left and right sides symmetrical openings of motor shaft.
Further, adjust the size of air inlet by regulating the size of described cam, to adjust the size of air quantity and noise.
Further, the shape of cross section of flabellum is that umbilicate analog-U shaped structure is equalled on both sides.
Further, the arrangement mode of described flabellum array is become 53 degree of arrangements along the tangential direction connecting annulus.
Further, when adjusting air port, keep motionless parallel with the tangential direction of impeller unit of air outlet, regulate the position of another side to regulate openings of sizes.
Further, the air outlet of described shell has little groove, in order to connect fixing wind-guiding flexible pipe.
Further, the electrical installation of this fan assembly can be installed in any direction according to base.
Further, having gap between this fan assembly and base, this gap silencing cotton is filled.
The Novel vane-free fan device of the present invention really realizes super-silent, the bladeless fan that air output is big.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As it is shown in figure 1, the Novel vane-free fan device of the present invention, including: impeller unit 1 and the shell with wind guide tank 2, the occlusion of described shell about 2 forms.
As in figure 2 it is shown, impeller unit 1 includes the bottom surface 3 with reinforcement, center, bottom surface 3 has motor and installs axis hole 4；It is perpendicular to the cam 5 for fixing motor shaft of bottom surface 3, is perpendicular to the flabellum array 6 of bottom surface 3 and for connecting the annulus 7 being parallel to bottom surface 3 of all flabellum arrays 6.
Cam 5 height for fixing motor shaft of impeller unit 1 should be not more than the height of flabellum array 6, is adjusted the size of air inlet by the size of adjustment cam 5, to adjust the size of air quantity and noise.
The flabellum number of flabellum array 6 according to the size needs of air output and noise ratio, can select between 5 to 44.As shown in Figure 4, the shape of cross section of flabellum is that umbilicate analog-U shaped structure is equalled on both sides, and the arrangement mode of flabellum array 6 is become 53 degree of arrangements along the tangential direction connecting annulus.
As it is shown on figure 3, about the 2 points two parts occlusions of shell with wind guide tank are installed.Above-mentioned impeller unit 1 is arranged on the middle of shell 2, the wind guide tank 8 of shell 2 is installing circular mounting hole 9 left and right sides symmetrical openings of motor shaft, openings of sizes is according to how many size and flabellum numbers of above-mentioned impeller unit 1 regulate, the one side keeping air outlet 10 parallel with the tangential direction of impeller unit 1 is motionless, regulates the position of another side to regulate openings of sizes.
The air outlet of shell 2 has little groove 11, in order to connect fixing wind-guiding flexible pipe.
As it is shown in figure 5, this fan assembly can level be installed；As shown in Figure 6, this fan assembly can right angle setting.
The Novel vane-free fan device advantage of the present invention is in that:
The dual openings air outlet along impeller tangential direction of fan assembly designs；
The open design of the Impeller Design of said fans device and air inlet and air outlet.Mix Computer Simulation by strict calculating and draw suitable parameter, it is ensured that the size of air output and the ratio of noise, in most suitable ratio, really fundamentally solve bladeless fan air quantity little, the defect that noise is big.
When level installs motor, the wind of air outlet is sent in air channel through wind-guiding flexible pipe, so the electrical installation of fan assembly arbitrarily can be installed according to the design of base, change and carry out unalterable right angle setting mode in the past, it is possible to adopt right angle setting can also adopt horizontal mounting means.
After installation, having gap between fan assembly and base, this gap silencing cotton is filled, and bottom surface and the surface of base are coated with silencing cotton.
During right angle setting motor, sending in air channel through a submissive surface extending of motor air outlet, the design of the similar wing of this curved surface makes wind not produce big eddy current when against non-plane motion, thus effectively reducing noise.
