Blade and multiple quaterfoils, first blade, the second blade, root and the current collector of third blade and quaterfoil
Connection, first blade, the second blade, the length of third blade and quaterfoil increase successively；And
5th blade of the impeller body upper surface being arranged between first blade and the second blade；
Wherein, the angle between adjacent first blade, the second blade, third blade and quaterfoil is different from each other.
Alternatively, gradually become to the differential such as length of first blade, the second blade, third blade and quaterfoil
Change.
Alternatively, the differential such as angle between adjacent first blade, the second blade, third blade and quaterfoil
Gradually change.
A kind of impeller assembly provided by the utility model, by being circularly set successively in the more of the impeller body upper surface
Individual first blade, multiple second blades, multiple third blades and multiple quaterfoils, first blade, the second blade, the 3rd
The root of blade and quaterfoil is connected with the current collector, first blade, the second blade, third blade and quaterfoil
Length increase successively；And it is arranged on of the impeller body upper surface between first blade and the second blade
Five blades；Angle between adjacent first blade, the second blade, third blade and quaterfoil is arranged to each other not
Together, so that when impeller works, frequency noise caused by each blade is different, so that it is big to reduce total noise caused by impeller
It is small.First blade, the second blade, the length of third blade and quaterfoil increase successively, also cause partial blade edge far from leaf
The Distance Shortened at piece center, so that blade edge stress reduces, to improve its performance, increase the service life.
According to the accompanying drawings will be more to the detailed description of the utility model specific embodiment, those skilled in the art
Add clear of the present utility model above-mentioned and other purposes, advantages and features.
Brief description of the drawings
It is described in detail by way of example, and not by way of limitation with reference to the accompanying drawings hereinafter more of the present utility model specific real
Apply example.Identical reference denotes same or similar part or part in accompanying drawing.It should be appreciated by those skilled in the art that
What these accompanying drawings were not necessarily drawn to scale.In accompanying drawing：
Fig. 1 is the structural representation figure according to a kind of impeller assembly of the utility model one embodiment；
Fig. 2 is that the side view structure of the impeller assembly shown in Fig. 1 is schematically schemed.
Embodiment
Fig. 1 is the structural representation figure according to a kind of impeller assembly of the utility model one embodiment；Fig. 2 is Fig. 1 institutes
The side view structure of the impeller assembly shown is schematically schemed.A kind of impeller assembly of the present utility model is carried out with reference to Fig. 1 and Fig. 2
Describe in detail.As shown in figure 1, a kind of impeller assembly provided by the utility model, in general manner, can include the impeller sheet of plate-like
Body 1, current collector 2, multiple first blades 3, multiple second blades 4, multiple third blades 5 and multiple quaterfoils 6 and the 5th
Blade 7.Current collector 2 is arranged on the center of impeller body 1 of plate-like, for focused airflow.Multiple first blades 3, multiple second leaves
Piece 4, multiple third blades 5 and multiple quaterfoils 6 are circularly set in the upper surface of impeller body 1 successively.First blade 3,
The root of two blades 4, third blade 5 and quaterfoil 6 is connected with current collector 2 respectively.First blade 3, the second blade the 4, the 3rd
The length of blade 5 and quaterfoil 6 is different from each other and increases successively.Adjacent first blade 3, the second blade 4, the 3rd leaf
Angle between piece 5 and quaterfoil 6 is different from each other.5th blade 7 is arranged on the leaf between the first blade 3 and the second blade 4
Take turns the upper surface of body 1.
Specifically, the upper surface of impeller body 1 is once provided with some groups of the first blades 3, the second blade 4, the and of third blade 5
Quaterfoil 6.First blade 3, the second blade 4, third blade 5 and quaterfoil 6 are disposed adjacent respectively, and the first adjacent leaf
Angle, adjacent third blade 5 between angle between the blade 4 of piece 3 and second, the second adjacent blade 4 and third blade 5
Angle between quaterfoil 6, the size of angle between the adjacent blade 3 of quaterfoil 6 and first are different from each other.First
Blade 3, the second blade 4, the length of third blade 5 and quaterfoil 6 are also different.By the length of each blade it is different and
The different designs of angle between each blade so that frequency noise caused by each blade is different, so that reducing caused by impeller
Total noise level.Other first blade 3, the second blade 4, the length of third blade 5 are shorter so that the first blade 3, the second blade
4th, Distance Shortened of the blade edge of third blade 5 away from blade center (at current collector 2), so that blade edge stress reduces,
And then improve its performance, increase the service life.
In a specific embodiment, the first blade 3, the second blade 4, the length of third blade 5 and quaterfoil 6
Etc. differential gradually change, angle between adjacent first blade 3, the second blade 4, third blade 5 and quaterfoil 6 etc.
Gradually change to differential.By controlling the size of angle and the length of each blade between each blade, control and make an uproar caused by each blade
The size of voice frequency and noise, it is final to realize the purpose for reducing total noise level caused by impeller.
A kind of impeller assembly provided by the utility model, by being circularly set successively in the more of the impeller body upper surface
Individual first blade, multiple second blades, multiple third blades and multiple quaterfoils, first blade, the second blade, the 3rd
The root of blade and quaterfoil is connected with the current collector, first blade, the second blade, third blade and quaterfoil
Length increase successively；And it is arranged on of the impeller body upper surface between first blade and the second blade
Five blades；Angle between adjacent first blade, the second blade, third blade and quaterfoil is arranged to each other not
Together, so that when impeller works, frequency noise caused by each blade is different, so that it is big to reduce total noise caused by impeller
It is small.First blade, the second blade, the length of third blade and quaterfoil increase successively, also cause partial blade edge far from leaf
The Distance Shortened at piece center, so that blade edge stress reduces, to improve its performance, increase the service life.
So far, although those skilled in the art will appreciate that herein it is detailed have shown and described it is of the present utility model more
Individual exemplary embodiment, still, still can be public according to the utility model in the case where not departing from the spirit and scope of the utility model
