AI Technical Summary
In some specific usage environments, the noise requirements of the impeller are high, and the prior art is difficult to effectively reduce noise under the same air volume and the same power. It is usually necessary to reduce noise by adding sound insulation materials, resulting in air volume, power and noise. In proportional.
The spherical centrifugal impeller design is adopted. By setting the motor shaft mounting member and the hub plate along the thickness direction at the center, the blade connection is used to form a spherical structure. The diameter of the hub plate increases from the inside to the outside, forming an inclined air outlet angle, and enlarges the output. Wind surface to reduce noise.
Under the same power and air volume, the spherical centrifugal impeller effectively reduces noise, and makes reasonable use of space to reduce impeller thickness and further reduces noise.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of fan impellers, and particularly relates to a spherical centrifugal impeller. Background Art
[0002] In some specific usage environments, the noise requirements for the impeller are relatively high, and many require noise reduction treatment, such as setting sound insulation materials. Power, air volume and noise are often proportional. The greater the air volume and power, the higher the noise will generally be. Therefore, how to reduce noise under the same air volume and power is our research and development direction. Utility Model Content
[0003] The utility model provides a spherical centrifugal impeller, which can solve the problems pointed out in the background technology.
[0004] A spherical centrifugal impeller includes a motor shaft mounting part located at the center and at least one hub piece coaxially arranged with the motor shaft mounting part and arranged along the thickness direction. The hub piece and the motor shaft mounting part and adjacent hub pieces are connected by a plurality of blades to form a spherical structure with intervals between the blades.
[0005] Preferably, the diameter of the hub piece increases from the inside to the outside, and the diameter of the innermost hub piece is larger than the outer diameter of the motor shaft mounting component to form a spherical structure.
[0006] Preferably, the number of the hub plates is two.
[0007] Preferably, the angle between the hub plate and the impeller rotation plane is 15-50 degrees.
[0008] Beneficial effects: The utility model provides a spherical centrifugal impeller which adopts a spherical structure so that the air outlet surface is much larger than the air inlet surface, thereby effectively reducing noise under the condition of equal power and air volume. The hub piece has an inclined air outlet angle, which further increases the air outlet surface and further reduces noise. The spherical setting can reasonably utilize space and the thickness of the impeller can also be relatively reduced. BRIEF DESCRIPTION OF THE DRAWINGS
