Problems solved by technology

However, placing the balance object into the groove with a tool will make it difficult to separate the tool and the balance object due to the high viscosity of the balance object, which will cause inconvenience in operation and make the calibration of the balance extremely time-consuming
Or, due to the design of the existing groove, the balance is easy to overflow when the impeller rotates, reducing the effect of balance correction
Even, the impeller must be separated from the motor to place the counterweight, which also causes inconvenience when correcting the rotational balance

Embodiment Construction

[0028] The impeller according to a preferred embodiment of the present invention will be described below with reference to related drawings, wherein the same components are described with the same reference numerals.

[0029] image 3 An impeller according to a preferred embodiment of the present invention. The impeller 20 includes a hub 21 and a plurality of blades 22 disposed around the periphery of the hub 21 . Each blade 22 is connected by an annular structure 26 and the annular structure 26 is concentric with the hub 21 .

[0030] Figure 4A for image 3 Magnified view at X. exist Figure 4A Among them, the end surface of the annular structure 26 has a plurality of concave holes 23A. Since the concave hole 23A can be filled with a balance object, the effect of correcting the rotation balance of the impeller and adding balance can be achieved according to the manufacturer's requirements.

[0031] In the present invention, the ring structure 26 is not limited to ima...

Abstract

The invention discloses an impeller, which comprises a wheel hub and a plurality of fan blades; wherein the fan blades are arranged the circumference of the wheel hub and connected by a ring structure. The end surface of the ring structure is provided with a plurality of concave holes for the placement of balance substances. In addition, the invention also provides a fan comprising the impeller. The impeller and the fan provided in the invention can improve the stability when rotating, and thereby increasing the reliability and service life of the product.

Description

technical field [0001] The invention relates to a fan and its impeller, in particular to a fan with stable rotation balance and its impeller. Background technique [0002] Nowadays, fans are widely used by the public. Because the fan is a device that creates a pressure difference by rotating the impeller to generate air flow, the balance of the impeller rotation is the basic requirement of the manufacturer. [0003] Existing fans include an impeller and a motor that drives the impeller. Such as figure 1 As shown, a general impeller 10 includes a hub 11 and a plurality of fan blades 12 surrounding it. In order to further correct the impeller 10 during the rotation shake test, the hub 11 is provided with a plurality of grooves 13 , and the manufacturer can put appropriate amount of balance objects into the grooves 13 to correct the rotation balance of the impeller 10 . [0004] Also have existing impeller to utilize its wheel hub and the remaining space of motor assembly t...
