Abstract
The utility model is related to a kind of novel fan vane, including shell, the outer casing inner wall is provided with helical blade, described shell one end is provided with support frame, rotating shaft is provided with the shell, the rotating shaft runs through described shell one end, sealing ring is provided between the rotating shaft and the support frame, the rotating shaft is provided with two groups of internal fan leaves, three blades are equipped with the internal fan leaf, arc groove is equipped with the blade, the utility model is spinned motion because external spiral blade and cylinder are more beneficial for air as an entirety in cylinder, it is unlikely to air to leak 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
Outer casing inner wall is stated 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 passed through
Described shell one end is worn, sealing ring is provided between the rotating shaft and the support frame, the rotating shaft is provided with two groups of internal fans
It is equipped with leaf, the internal fan leaf on three blades, the blade and is equipped with arc groove.
It is preferred that, the internal fan leaf passes through nut connection rotating shaft.
It is preferred that, the helical blade is flexibly connected shell by nut.
It is preferred that, the shell is drum.
It is preferred that, the arc groove is located at blade edge.
It is preferred that, the number of the arc groove and blade is three.
The beneficial effects of the utility model are：The utility model more has due to external spiral blade and cylinder as an entirety
Spinned beneficial to air in cylinder motion, be unlikely to air and leaked hunting from blade edge；Two groups of internal fan leaves being distributed in rotating shaft
The screw for coordinating external spiral blade to strengthen air is increased the flowing velocity and efficiency of air by piece, while adding on blade
Enter arc groove, further increase air quantity.

Fig. 1,2,3, a kind of novel fan vane, including shell 1 are referred to, the inwall of shell 1 is provided with helical blade 2,
Helical blade 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 and protected
Rotating shaft 4 is provided with the effect of shield, the shell 1, the rotating shaft 4 runs through described one end of shell 1, the rotating shaft 4 and the support
Sealing ring is provided between framework 3, rotating shaft 4 drives fan leaf to rotate, and the rotating shaft 4 is provided with two groups of internal fan leaves 5, internal fan leaf
5 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 groove 7,
Arc groove 7 plays a part of increasing air quantity.
The internal fan leaf 5 is flexibly connected shell 1, institute by nut connection rotating shaft 4, the helical blade 2 by nut
Shell 1 is stated for drum, the arc groove 7 is located at the edge of blade 6, and when rotated, the circuit of edge is most for blade 6
It is long, produce distinguished and admirable effect preferably, the number of the arc groove 7 and blade 6 is three.
When in use, the utility model rotating shaft 4 drives internal fan leaf 5 to rotate and produces distinguished and admirable, internal fan leaf 5 the utility model
Air leakage phenomena can be produced in rotation process, 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 increases the air quantity produced during being rotated with blade 6, further.
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
