Problems solved by technology

However, the longer length of the air duct will increase the wind resistance of the airflow generated by the fan in the blower pipe, which will cause the loss of airflow velocity; on the other hand, it will cause the machine to be heavier
In order to minimize the loss of airflow velocity and reduce the weight of the machine, one solution is to shorten the length of the air duct to reduce the volume of the air duct, but this will bring new challenges to the comfort of machine operation and machine performance

Abstract

The invention provides a hair drier. The hair drier comprises an operating handle; the air inlet cover is provided with a plurality of protective cover holes; an air duct part; the axial fan is arranged in the air duct part; a motor; the blower further comprises a supporting piece extending in the longitudinal direction, the supporting piece is connected with the air inlet cover through a first end, and the supporting piece is connected with the operating handle through a second end. The projection of the first end falling on a rotating surface formed by rotation of the axial fan in the longitudinal extending direction of the supporting piece is always located in the outer contour range of the rotating surface of the axial fan, the cross sectional area of the air inlet cover is smaller than 13300 mm < 2 >, the air inlet cover is provided with an inserting part, and the air blower further comprises a first connecting structure; the first end of the supporting piece is connected with the air inlet cover through the first connecting structure. The orthographic projection of the first connecting structure on the rotating surface does not coincide with the orthographic projection of the shield hole on the rotating surface basically. The hair dryer is compact in structure, and the use feeling of a user is improved.

Description

technical field [0001] The present application relates to an electric tool, in particular to a hair dryer. Background technique [0002] As a relatively conventional electric tool, the blower can be used to blow off fallen leaves, road dust, accumulated water, snow and forest fires. The hair dryer generally includes: a casing, an operating handle formed on the casing, a motor contained in the casing, a fan driven by the motor, a duct at the front end of the casing, a flow guiding mechanism arranged in the duct, a connecting The blowpipe at the front end of the duct. The working principle is roughly as follows: the motor drives the fan to generate airflow, and after the airflow is guided by the deflector mechanism, it is blown out through the front opening of the blowing pipe. The user operates the operating handle by hand, and aligns the front end of the blowing pipe with the target object (for example, fallen leaves, dust, water accumulation, snow accumulation, flames, et...
