  • Patent number: 10883514
    Abstract: A blower fan including an impeller easily mounted on the rotational shaft of a motor generates less noise. The impeller is mounted on the rotational shaft of the motor using a fastener with an elastic vibration isolator and a washer in between. The washer has a predetermined shape including radial projections from a circumference about a central receiving hole. The vibration isolator has the predetermined shape larger than the predetermined shape of the washer, and has a first recess having the predetermined shape on its top surface to receive the washer fittingly. The impeller has a second recess having the predetermined shape on its top surface to receive the vibration isolator fittingly. The vibration isolator thus separates the impeller mounted on the rotational shaft from the washer in both the axial and rotational directions of the motor to reduce vibrations in both directions propagating to the impeller, generating less noise.
