Relationship description word.
Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in Figure 1 to Figure 3, the utility model provides a kind of impeller 100, including the wheel hub 11 of general conical and along week
To multiple blades 12 of the arranged for interval on the outer peripheral face of wheel hub 11, each blade 12 is included positioned at the leading edge face 121 of entrance point
With the rear surface 122 positioned at the port of export, the blade 12 is flat board twisted blade, the trailing edge section of the blade 12 relative to
Circumferencial direction turn-knob tilts.
Preferably, the trailing edge section is inclined relative to the direction of rotation w of the impeller 100 towards the turn-knob of upstream side 21
Tiltedly.It should be noted that trailing edge section is also not necessarily limited to 21 reverse to the upstream side, for same impeller 100, figure can be also in reverse to
The direction of rotation w rotations shown, but efficiency relative mistake.
Because the rear rim segment of blade 12 21 is reversed to the upstream side, be advantageous to be bonded fluid conduction, it is recessed after especially reversing
Shape face 126 is streamlined etc..In a word, by being distorted to the trailing edge of plate blade, impeller 100 of the present utility model can effectively subtract
The fluid loss of the port of export of vanelets 12, expand work area of the impeller 100 in the case of low discharge, that is, add effectively

Height is gradually successively decreased.Specifically, i.e., from the height b2 of height b1 to the rear surface 122 in the leading edge face 121 of blade 12 be by
Gradually successively decrease.Wherein it is preferred to meet respectively：5mm≤b1≤9mm, 2mm≤b2≤5mm.In other words, before each blade 12
The leaf top surface 123 in edge face 121 is maximum relative to the height value b1 of the blade root 124, and is limited to 5mm≤b1≤9mm, each
The leaf top surface 123 of the rear surface 121 of blade 12 is minimum relative to the height value b2 of the blade root 124, and is limited to 2mm≤b2
≤ 5mm, the height between the maximum height b1 and minimum constructive height b2 of blade 12 are gradually successively decreased.Pass through the blade height
Design and limitation, the volume of blade 12 while the structural strength and service behaviour of blade 12 is ensured, can be reduced, so as to drop
The weight of low whole blower fan.
To realize airflow design, the blade root edge line of the blade root 124 is preferably from the bottom in the leading edge face 121
Extend to the smoothed curve of the bottom of the rear surface 122.
In addition as shown in figure 3, the stagger angle of blade 12 is β 1, exit installation angle is β 2, and is met：30°≤β1≤
80 °, 2≤80 ° of 40 °≤β.Specifically, with reference to shown in Fig. 1, the blade root edge line of the blade root 124 of blade 12 is the side of blade 12
Face and the intersecting lens of the outer peripheral face of wheel hub 11, i.e. intersection curve between face and face, thus the stagger angle of blade 12 is leaf
Angle between the first tangent line and the second tangent line most at leading edge point of root edge line.First tangent line is blade root edge line
Most leading edge point relative to the blade root edge line tangent line, second tangent line be the most leading edge point relative to the most leading edge point with
