Abstract

The invention relates to a blower. The blower comprises a casing, a motor, an axial flow fan, a blowpipe and a duct, wherein a wind inlet is formed in the casing, and air enters the casing through the wind inlet; the motor is positioned in the casing; the axial flow fan is driven by the motor to rotate along a fan axis and generate air currents; the blowpipe is connected with the casing and is provided with a wind outlet, and the air currents are blown out of the wind outlet; the duct is used for guiding the air currents to move towards the wind outlet; air current passages are arranged in the casing and the blowpipe, and comprise an upstream region from the wind inlet to the axial flow fan and a downstream region from the axial flow fan to the wind outlet, the motor is arranged at the upstream region, and the duct is arranged at the downstream region.

Description

technical field [0001] The invention relates to an electric tool, especially a hair dryer. Background technique [0002] In daily life, a hair dryer is a relatively common tool, usually used to clean up grounds such as gardens or streets. [0003] For example, US Patent No. 4,880,364 discloses a hair dryer, which includes a housing, a motor, a fan, and an air duct. The fan rotates to generate airflow, which is blown out from the air duct. But what the fan of this kind hair dryer adopts is a centrifugal fan, and the air inlet is arranged below the centrifugal fan, and the air outlet is arranged at the side of the centrifugal fan. Due to the limitation of the structure of the centrifugal fan itself, the air volume blown out by this kind of hair dryer is often not large, so the blowing effect is not good, and the needs of users cannot be well met. [0004] Disclosed a kind of blower that adopts engine as power as U.S. Patent No. 5975862, engine utilizes gasoline as fuel as p...
