AI Technical Summary
Existing fan motors suffer from increased outer diameter and reduced flow efficiency during miniaturization and weight reduction, especially due to air leakage and adhesive blockage between the impeller cover and guide vanes.
By designing the outer circumferential surface of the impeller cover and the inner circumferential surface of the guide blade as an insertable structure, and using adhesive to seal them together, the outer diameter of the impeller cover is reduced. Adhesive is applied to the outer circumferential surface of the insertion part to prevent flow path blockage. Cover joint groove and joint groove are used to enhance the bonding effect.
This technology enables the miniaturization and weight reduction of the fan motor, while improving suction power and preventing a decrease in flow path efficiency, thus avoiding the reduction in flow path efficiency caused by adhesive clogging.
