AI Technical Summary

Benefits of technology

The blower achieves higher blowing efficiency with reduced power consumption and noise, while maintaining a compact size and environmentally friendly operation, enhancing user comfort and operational ease.

Problems solved by technology

Owing to the limitation of the structure of the centrifugal fan per se, the volume of air exiting is often not great, and thus the blowing effect is not good, which cannot well meet users' demands.
However, as the blower using a gasoline engine often has greater work noise and uses gasoline to supply energy, it is easy to form atmospheric pollution, which is not environment-friendly enough.
However, the engine is disposed outside the housing, to cause the engine to be farther from the fan, and the volume of the whole blower seems to be greater; in addition, the engine is bulky, and does not conform to the portable and lightweight development trend.

Abstract

A blower includes a housing having an air inlet; a motor; an axial fan, driven by the motor to rotate along a fan axis and generate air flow, and the axial fan comprising a hub and impeller; a blowing tube, comprising an air outlet for the air exiting; and a duct, comprising a guiding cone which is located between the axial fan and the air outlet, and used for guiding the air flow generated by the axial fan to move to the air outlet, wherein a size of the motor is configured in a manner that the motor cannot be contained in the guiding cone, the housing and the blowing tube are internally provided with an air passage, the motor is completely contained in the air passage of the housing, and the motor and the duct are located on two opposite sides of the axial fan.
