Utility model content
The purpose of this utility model is to provide a kind of blower fan blades, can avoid the installation of cutter, pass through
First inclined cut face and the second inclined cut face are used cooperatively, and effectively improve cutting effect, reduce drive energy and production
Cost.
In order to achieve the above object, the technical solution of the utility model is：
A kind of blower fan blade including fan blade ontology, offers axis installation through-hole on the fan blade ontology, described
First blade of 1 or more is equidistantly installed, first blade positioned at axis installation through-hole side on fan blade ontology side
On offer the first inclined cut face, be equidistantly equipped with 1 on the fan blade ontology between first blade and axis installation through-hole
The second more than piece blade offers the second inclined cut face on second blade；The fan blade ontology opposite side is first-class
Away from the third blade for being equipped with 1 or more.
The first inclined cut face counterclockwise from bottom to top is offered on first blade, is offered on second blade
Second inclined cut face clockwise from bottom to top.
Axle sleeve is installed on the fan blade ontology outside the axis installation through-hole, opened up on the fan blade ontology it is fluted,
Reinforcement block is installed, the reinforcement block is connected respectively with fan blade ontology, axle sleeve in the groove.
Triangle convex is installed, the side of the triangle convex is connected with the first inclined cut face on first blade
Installation.
First blade with triangle convex is integrally manufactured forms.
7 first blades are equidistantly installed on the fan blade ontology side.
3 second blades are equidistantly installed on the fan blade ontology between first blade and axis installation through-hole.
12 third blades are equidistantly installed on the fan blade ontology opposite side.
The beneficial effects of the utility model are：A kind of blower fan blade, can avoid the installation of cutter, pass through
One inclined cut face and the second inclined cut face are used cooperatively, and effectively improve cutting effect, are reduced drive energy and are produced into
This.

Specific embodiment
Embodiment 1
A kind of blower fan blade as shown in Figure 1 and Figure 2 including fan blade ontology 1, offers on the fan blade ontology 1
Axis installation through-hole 2 is equidistantly equipped with first blade 3 of 1 or more on 1 side of fan blade ontology, positioned at axis installation through-hole 2
The first inclined cut face 4, the wind between first blade 3 and axis installation through-hole 2 are offered on first blade 3 of side
Second blade 5 of 1 or more on impeller body 1 is equidistantly installed, the second inclined cut face 6 is offered on second blade 5；
The third blade 7 of 1 or more is equidistantly installed on 1 opposite side of fan blade ontology.
The first inclined cut face 4 counterclockwise from bottom to top is offered on first blade 3, is opened on second blade 5
Equipped with the second inclined cut face 6 clockwise from bottom to top.
Axle sleeve 8 on the fan blade ontology 1 outside the axis installation through-hole 2 is installed, is offered on the fan blade ontology 1 recessed
Slot 9 is equipped with reinforcement block 10 in the groove 9, and the reinforcement block 10 is connected respectively with fan blade ontology 1, axle sleeve 8.
Triangle convex 11, the side of the triangle convex 11 and the first inclined cut face 4 are installed on first blade 3
Be connected installation.First blade 3 with triangle convex 11 is integrally manufactured forms.The setting of triangle convex 11 can be carried further
The cutting effect of high first blade 3.
7 first blades 3 are equidistantly installed on 1 side of fan blade ontology.First blade 3 and axis installation through-hole
3 second blades 5 are equidistantly installed on the fan blade ontology 1 between 2.It is equidistantly equipped on 1 opposite side of fan blade ontology
12 third blades 7.
Blower fan blade described in the present embodiment inclines due to offering counterclockwise from bottom to top first on the first blade 3
Face 4 is chamfer, the second inclined cut face 6 clockwise from bottom to top, therefore 3 He of the first blade are offered on second blade 5
Second blade 5 can form leaf, the branch of scissor cutting sucking, and sawtooth, this reality are opened up on blade compared to better simply
The cutting effect for applying example is more preferable.Simultaneously because the first blade 3, the second blade 5, and second are installed simultaneously on fan blade ontology 1
Blade 5 has filled up the gap between the first blade 3 and axis installation through-hole 2, so as to improve the air output of blower.The present embodiment institute
The fan blade ontology 1 and blade stated are that metal is made, therefore the setting of reinforcement block 10 can improve 8 mounting stability of axle sleeve,
So as to reduce noise.
A kind of blower fan blade of the present embodiment, can avoid the installation of cutter, pass through the first inclined cut face
With being used cooperatively for the second inclined cut face, cutting effect is effectively improved, reduces drive energy and production cost.
