Abstract
The utility model is related to a kind of novel fan vane, including shell, the shell is provided with helical blade, described shell one end, which is provided with support frame, the shell, is provided with rotating shaft, and the rotating shaft is provided with two groups of internal fan leaves, three blades are equipped with the internal fan leaf, it is equipped with arc groove on the blade, external spiral blade and cylinder are more beneficial for air as an entirety and spinned in cylinder motion, are unlikely to air and are leaked hunting from blade edge；The screw for coordinating external spiral blade to strengthen air is increased the flowing velocity and efficiency of air, while adding arc groove on blade, further increases air quantity by two groups of internal fan blades being distributed in rotating shaft.
Description
Technical field
The utility model is related to a kind of novel fan vane.
Background technology
Fan, have small-sized household, also have large-sized workshop, there is various sizes of fan to carry depending on different use occasions
For using, but purpose is all identical, is provided to provide the air circulation of use occasion, increases cross-ventilation, keeps room air
Pure and fresh, the helical blade and shell of existing conventional fan are separated from each other, and blade is rotated relative to shell, this structure meeting
Air is set to be leaked hunting from blade edge；It is less into the air in blade and conventional helical blade fan only has one group of blade, blowout
The intensity of the wind gone is smaller, and noise is larger, it is difficult to meet the demand in market.
Utility model content
The purpose of this utility model is that provides a kind of novel fan vane to solve the above problems.
The utility model is achieved through the following technical solutions above-mentioned purpose：A kind of novel fan vane, including shell, institute
Shell is stated provided with helical blade, described shell one end, which is provided with support frame, the shell, is provided with rotating shaft, is set in the rotating shaft
Have to be equipped with three blades, the blade on two groups of internal fan leaves, the internal fan leaf and be equipped with arc groove.
It is preferred that, the internal fan leaf is fixedly connected with rotating shaft.
It is preferred that, the helical blade is fixedly connected with shell.
It is preferred that, the shell is drum.
It is preferred that, the arc groove is located at blade edge.
The beneficial effects of the utility model are：External spiral blade and cylinder are more beneficial for air in cylinder as an entirety
Inside spin motion, be unlikely to air and leaked hunting from blade edge；Two groups of internal fan blades being distributed in rotating shaft will coordinate external spiral
Blade strengthens the screw of air, increases the flowing velocity and efficiency of air, while adding arc groove on blade, enters one
Step increases air quantity.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment, based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Fig. 1,2,3, a kind of novel fan vane, including shell 1 are referred to, the shell 1 is provided with helical blade 2, spiral shell
Vane piece 2 prevents fan leaf edge from leaking out, and described one end of shell 1 is provided with support frame 3, and support frame 3 plays support protection
Effect, rotating shaft 4 is provided with the shell 1, rotating shaft 4 drives fan leaf to rotate, the rotating shaft 4 provided with two groups of internal fan leaves 5,
Internal fan leaf 5 is by rotating, and generation is distinguished and admirable, is equipped with the internal fan leaf 5 on three blades 6, the blade 6 and is equipped with arc
Connected in star 7, arc groove 7 plays a part of increasing air quantity.
The internal fan leaf 5 is fixedly connected with rotating shaft 4, and the helical blade 2 is fixedly connected with shell 1, and the shell 1 is cylinder
Shape, the arc groove 7 is located at the edge of blade 6, and when rotated, the circuit of edge is most long for blade 6, produces distinguished and admirable effect
It is really best.
When in use, it is distinguished and admirable that rotating shaft 4 drives the rotation of internal fan leaf 5 to produce to the utility model, and internal fan leaf 5 is in rotation process
In can produce air leakage phenomena, it is distinguished and admirable to be blown away along helical blade 2 to outlet, the phenomenon leaked out will not be produced, arc groove 7 exists
During being rotated with blade 6, the air quantity produced is further increased.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can realize that this practicality is new in other specific forms
Type, therefore, no matter from the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, and this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limitation
Involved claim.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
It may be appreciated other embodiment.
