It is preferred that, in addition to some first connectors, wing flange is fixedly connected on housing by each first connector.
It is preferred that, in addition to some second connectors, guide assembly is fixedly connected on housing by each second connector.
It is preferred that, in addition to some 3rd connectors, each adjacent air guide member is fixedly connected by the 3rd connector.
It is preferred that, each air guide member is cylindrical in shape, and the two ends of each air guide member are open state；The cavity of each air guide member according to
It is secondary to connect and be formed as the passage.
It is preferred that, the internal diameter of each air guide member is gradually reduced along the direction away from wing flange.
Compared with prior art, the beneficial effects of the utility model are：
By using wing flange, a lift is obtained；By using guide assembly, it can be obtained by wall attachment effect
Another lift, therefore substantially increase the lift of ducted fan；Simultaneously surrounding can be prevented by using guide assembly
Air produces interference with the air-flow sprayed, ducted fan is more stablized.

Embodiment
Below, with reference to accompanying drawing and embodiment, the utility model is described further：
As shown in Fig. 1~5, a kind of ducted fan, including housing 1, wing flange 7, fan body 2 and guide assembly 3, shell
Body 1 has the chamber through two ends, and fan body 2 is in chamber and coaxial with housing 1, and wing flange 7 has opening 4 and the wing
Shape flange 7 is fixedly connected on one end of housing 1, and guide assembly 3 is fixedly connected on the other end of housing 1, and guide assembly 3 has logical
Road 8, and opening 4, passage 8 are and chamber；The first air intake duct 5 is formed between guide assembly 3 and housing 1；Guide assembly 3 is wrapped
Some air guide members 9 are included, axis of each air guide member 9 along housing 1 is sequentially arranged at intervals, and two air guide members 9 of arbitrary neighborhood
Between form the second air intake duct 6.
When fan body 2 is rotated, air is promoted to pass sequentially through opening 4, chamber and passage 8 from top to bottom, when air-flow warp
When crossing wing flange 7, because wing flange 7 is in wing, thus a lift can be produced；Because the high speed of fan body 2 rotates,
Air-flow is after fan body 2, and pressure and speed are obtained for raising, become high velocity air；When high velocity air is via chamber
When being sprayed from passage 8, according to wall attachment effect, substantial amounts of air will be via the first air intake duct 5 and the second air intake duct around housing 1
6 enter passage 8, so as to produce another lift, the lift produced when adding foregoing air-flow by wing flange 7 obtain
Two lift, compared with traditional ducted fan, the lift of acquisition is greatly improved, moreover, can also reduce electric power, combustion
The use of oil, can save the energy；Air cause simultaneously around smoothly enters passage 8, and will not be sent out with the air-flow of ejection
Raw interference, improves the stability of ducted fan.
As shown in Figure 4 and Figure 5, chamber 1 is less than the rotating diameter D of fan body 2 towards the diameter L of wing one end of flange 7,
When fan body 2 is rotated, air inversion can be effectively prevented, to lift fan body pressure difference about 2, duct wind is improved
The lift of fan.
As shown in figure 3, the inwall of the housing 1 slopes inwardly from the middle part of housing 1 to one end towards guide assembly 3,
And be preferably into nine degree of angles with the axis of housing 1；I.e. from the middle part of the inwall of housing 1 downwards, the internal diameter of housing 1 is gradually reduced,
Therefore when air enters from the upper end of housing 1, when being flowed out from lower end, because the internal diameter of the lower end of housing 1 is smaller, therefore formed at a high speed
Air-flow；According to air amplifier principle, wall attachment effect, first air intake duct 5 and second air intake duct 6 of the mass air flow from periphery are produced
Into so as to considerably increase capacity, reducing outer gas stream when duct aircraft (such as model plane) is flat to fly and wake flow done
Disturb, improve the stability of ducted fan.
As shown in Figures 1 to 3, ducted fan also includes some first connectors 10, and wing flange 7 passes through each first connector
10 are fixedly connected on housing 1, it is preferred that wing flange 7 is fixedly connected on housing 1 by each first connector 10 by welding.
Equally, ducted fan also includes some second connectors 11 and some 3rd connectors 12, and guide assembly 3 is by each
Second connector 11 is fixedly connected on housing 1, it is preferred that guide assembly 3 is fixedly connected by each second connector 11 by welding
In housing 1；Each adjacent air guide member 9 is fixedly connected by the 3rd connector 12, it is preferred that each 3rd connector 12 passes through welding
Each adjacent each air guide member 9 is fixedly connected.
It is preferred that, each air guide member 9 is cylindrical in shape, and the cavity of each air guide member 9 is sequentially communicated and is formed as the passage 8；Respectively lead
The internal diameter of wind part 9 is gradually reduced along the direction away from wing flange 7.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
It is corresponding to change and deformation, and all these change and deformation should all belong to the protection of the utility model claim
Within the scope of.
