The electric fan with multistage fan blade of raw interference.
A kind of electric fan with multistage fan blade of the present utility model, its technical scheme are：
It is used for the fan blade of output wind including at least two-stage, the nesting with accommodation space is designed with the middle part of every grade of fan blade
Ring, fan blades at different levels are sequentially embedded in the nested rings of one-level fan blade adjacent thereto to realize the socket of fan blades at different levels from small to large.
Wherein, every grade of fan blade is designed with axis hole, and the rotating shaft of motor sequentially passes through the axis holes of fan blades at different levels to drive provided with level
The rotation of fan blade.
Wherein, including two-stage fan blade, respectively first order fan blade and second level fan blade, second level fan blade are built in the first order
The nested rings of fan blade.
Wherein, it is provided with first drivening piece affixed with it in the nested rings of first order fan blade, the first drivening piece offers the
One axis hole, the nested rings of second level fan blade are interior to be provided with second drivening piece affixed with it, and the second drivening piece offers the second axis hole,
The rotating shaft of motor come through the first axis hole it is affixed with the second axis hole so that motor driven first order fan blade and the second level fan blade rotation
Turn.
Wherein, the rotating shaft of motor and the mode that the second axis hole is connected through a screw thread are affixed.
Wherein, the nested rings of second level fan blade are extended with towards its air-out direction and driven with its integrally formed knob, second
Part is in knob.
Wherein, dowel is provided between the nested rings of the first drivening piece and first order fan blade.
Wherein, dowel has a plurality of and uniform arrangement.
Wherein, multiple blades are uniformly placed with outside nested rings at different levels.
Implementation of the present utility model includes following technique effect：
Electric fan of the present utility model with multistage fan blade, its structure include the fan blade that at least two-stage is used for output wind,
The nested rings with accommodation space are designed with the middle part of every grade of fan blade, fan blades at different levels are sequentially embedded adjacent thereto one from small to large
To realize the socket of fan blades at different levels in the nested rings of level fan blade, so the central region of fan can not only be enabled to produce foot
Enough wind-force so that fan is realized blows without dead angle, and is set due to being that fan blades at different levels are nested, can not only avoid wind at different levels
The air-out of leaf institute interferes phenomenon, additionally it is possible to which so that the structure of fan is more compact, space-consuming is less, then causes fan
Monnolithic case simple and beautiful.

Embodiment
The utility model is described in detail below in conjunction with embodiment and accompanying drawing, it should be pointed out that described
Embodiment be intended merely to facilitate to understanding of the present utility model, and do not play any restriction effect to it.
Referring to a kind of electric fan with multistage fan blade that shown in Fig. 1 and Fig. 2, the present embodiment provides, its structure includes two
Level is used for the fan blade of output wind, and respectively first order fan blade 1 and second level fan blade 2, second level fan blade 2 is built in first order fan blade
1 nested rings 3, the nested rings 3 of first order fan blade 1 are interior to be provided with first drivening piece 11 affixed with it, and the first drivening piece 11 opens up
There is the first axis hole 12, be provided with second drivening piece 22 affixed with it in the nested rings 3 of second level fan blade 2, the second drivening piece 22 is opened
Provided with the second axis hole 23, the rotating shaft 41 of motor 4 is affixed so that motor 4 drives the first order through the first axis hole 12 and the second axis hole 23
Fan blade 1 and second level fan blade 2 rotate, because the first axis hole 12 and the second axis hole 23 are separate, after the damage of certain one-level fan blade,
Can easily it be replaced.Multiple blades are all uniformly placed with outside the nested rings 3 of first order fan blade 1 and second level fan blade 2,
The air current flow for driving its annex is produced wind-force by blade rotation.
First order fan blade 1, which rotates, enables to fan to drive the air flow and then output wind-force of its outer peripheral areas, and second
Level fan blade 2, which rotates, enables to fan to drive the wherein air flow in portion region and then the enough wind-force of output, first order fan blade 1
Mutually covered the shortage with second level fan blade 2 and reach comprehensive no dead angle air-supply, this addresses the problem fan in the prior art
Central region can not produce the technical problem of enough wind-force, and be set because the utility model is that fan blades at different levels are nested, no
Fan blade institutes at different levels air-out can only be avoided interferes phenomenon, additionally it is possible to so that the structure of fan is more compact, space-consuming
Less, fan monnolithic case simple and beautiful is then caused.
In the present embodiment, the rotating shaft 41 of motor 4 and the mode that the second axis hole 23 is connected through a screw thread are affixed, second level fan blade
2 nested rings 3 are extended with towards its air-out direction and are located at its integrally formed knob 21, the second drivening piece 22 in knob 21.It is logical
Crossing turning knob 21 can be locked at second level fan blade 2 in the rotating shaft 41 of motor 4, while the partial insertion of the first drivening piece 11
In the nested rings 3 of second level fan blade 2, second level fan blade 2 and first order fan blade 1 can also be locked together by turning knob 21,
Prevent second level fan blade 2 from releasing.
In the present embodiment, dowel 13, dowel are provided between the first drivening piece 11 and the nested rings 3 of first order fan blade 1
13 have a plurality of and uniform arrangement.Dowel 13 can not only mitigate the gravity of first order fan blade 1, and cause first order fan blade 1
Overall construction intensity enhancing, be hardly damaged it.
Finally it should be noted that above example is only illustrating the technical solution of the utility model, rather than to this reality
With the limitation of novel protected scope, although being explained with reference to preferred embodiment to the utility model, this area it is general
It is logical it will be appreciated by the skilled person that can be modified to the technical solution of the utility model or equivalent substitution, without departing from this
The spirit and scope of utility model technical scheme.
