Description

Wind impeller

Technical Field

The utility model belongs to the technical field of the fan, refer in particular to a fan impeller.

Background

At present, a fan is a machine which increases gas pressure and discharges gas by means of input mechanical energy, and is a driven fluid machine. The blower is a Chinese habit abbreviation for gas compression and gas conveying machinery, and the blower generally comprises a ventilator, a blower and a wind driven generator.

The most important fan impeller in the fan has a structure which influences the transmission efficiency of the fan, and the existing fan impeller in the existing market is often simple in structure and weak in optimization and treatment of gas, so that the fan is low in efficiency.

Disclosure of Invention

The utility model aims at providing a reduce the vortex to the impeller of efficiency is improved.

The purpose of the utility model is realized like this:

the utility model provides a wind impeller, includes the wheel hub that links mutually with the output shaft of motor to and connect on the wheel hub lateral wall and along a plurality of blades of circumference evenly distributed, the blade is the wing section, each the lower part shaping of blade has the blade root of downwardly extending and bottom surface cross-section for the arc, and the upper right corner of blade upwards extends and forms the apex, and the upper portion shaping of blade has the transition region that the thickness reduces gradually, and the outside shaping of blade has the wing that rises, and the thickness that is located the wing that rises of apex one end reduces gradually, the left side perpendicular to wheel hub's lateral wall of blade, and the side cross-section and the level of blade form the contained angle of 30 ~ 60.

The utility model discloses further set up to, the blade with the junction shaping of wheel hub has the hemisphere cambered surface of forward hunch-up, and this cambered surface sets up in the middle part of blade.

The utility model discloses it is further set up that the area ratio of transition region and blade is preferably 1: 4.

The utility model discloses further set up to, the vertical height of blade is 1.5 times of wheel hub vertical height.

The utility model discloses further set up to, be provided with a plurality of strengthening ribs in the wheel hub.

Compared with the prior art, the utility model outstanding and profitable technological effect is:

1. the utility model discloses a some transition regions of the blade shaping of wing section can reduce air resistance, make the impeller rotate more high-efficiently, rise the wing in addition and carry out the drainage to gas, reduce the vortex to raise the efficiency.

2. The utility model discloses a further hemisphere cambered surface that sets up can strengthen the fixed effect between blade and the wheel hub.

Detailed Description

The invention will be further described in the following with reference to specific embodiments thereof, with reference to the accompanying drawings, in which fig. 1 to 3:

a wind impeller comprises a hub 1 and a plurality of blades 2, wherein the hub 1 is linked with an output shaft of a motor, the blades 2 are connected to the outer side wall of the hub 1 and are uniformly distributed along the circumferential direction, each blade 2 is in an airfoil shape, a blade root 20 which extends downwards and is arc-shaped in bottom surface cross section is formed at the lower part of each blade 2, the upper right corner of each blade 2 extends upwards to form a blade tip 21, a transition area 22 with gradually reduced thickness is formed at the upper part of each blade 2, a lifting wing 23 is formed at the outer side of each blade 2, the thickness of the lifting wing 23 at one end of each blade tip 21 is gradually reduced, the left side of each blade 2 is perpendicular to the outer side wall of the hub 1, and the side cross section of each blade 2 forms.

When the motor rotates, drive hub 1's rotation, transition region 22 is windward mouthful cutting air current, and the transition region 22 that the thickness that has reduces gradually is less with air area of contact, can reduce the windage by a wide margin for this impeller rotates fast, rises in addition that wing 23 plays certain drainage effect with gas, is difficult for letting gas to run off from the outside of blade, reduces wind and disturbs, raises the efficiency.

Preferably, a forward-arched hemispherical arc surface 24 is formed at the joint of the blade 2 and the hub 1, the arc surface 24 is arranged in the middle of the blade 2, and the arc surface 24 structurally enhances the connectivity between the blade 2 and the hub, so that the wind impeller is efficient and continuously used.

Preferably, the area ratio of the transition region 22 to the blade 2 is preferably 1: 4.

Because the thickness of transition region 22 relative blade 2 will be a lot of littlely, so the area of transition region 22 accounts for blade 1 vertical plane proportion lessly, ensures blade 2's structural strength, the work efficiency when the guarantee uses.

Preferably, the vertical height of the blades 2 is 1.5 times that of the hub 1, and the structure can generate larger air inlet amount and improve higher rotating efficiency.

Preferably, a plurality of reinforcing ribs 10 are arranged in the hub 1, and the reinforcing rib structure enhances the structural strength of the hub 1.

The working principle is as follows:

the utility model adopts a unique blade 2 structure, wherein the transition region 22 with gradually reduced thickness can reduce the wind resistance, enhance the intake air quantity and improve the air intake effect, the elevating wing 23 enhances the drainage effect and reduces the wind disturbance, in addition, the thickness of the end of the elevating wing 23 positioned at the blade tip is gradually reduced, the effect of reducing the wind resistance is also achieved, thereby realizing the effect of improving the working efficiency,

the above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
