Problems solved by technology

In this new type of blower, the design parameters such as the overall size of the axial flow fan, the proportional arrangement of the fan hub and the fan as a whole, and the setting of the motor speed have not fully considered the combination of blowing efficiency and power consumption, resulting in The wind speed and air volume of the whole machine are small, and the blowing efficiency is low. It is difficult to blow the heavy leaves falling on the lawn and the leaves in the cracks, etc. or the blowing efficiency of the whole machine is guaranteed, but the power consumption is too high. When the battery pack is powered, the hair dryer can maintain a shorter working time

Embodiment Construction

[0058] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0059] Figure 1 to Figure 7Shown is a hair dryer 100 according to a first embodiment of the present invention. The hair dryer 100 includes a housing 200 , a motor 300 , a duct 400 , a fan 500 , and a blowing pipe 600 . Wherein, the motor 300 , the duct 400 and the fan 500 are all arranged in the casing 200 . The blowing pipe 600 is connected to the casing 200 . The air blowing pipe 600 is connected with the casing 200 to form an air flow channel 602 . The blowing pipe 600 is provided with an air outlet 601, and the air moves from the airflow channel 602 to the air outlet 601 and is blown out from the air outlet 601 for blowing away fallen lea...

Abstract

The invention provides a hair dryer. The air dryer comprises a shell, a motor, an axial fan, an air blowing pipe and a duct, wherein an air inlet is formed in the shell, and air enters from the air inlet; the motor is located in the shell; the axial fan is driven by the motor to rotate and generate airflow; the air blowing pipe is connected with the shell and provided with an air outlet, and airflow is blown out from the air outlet; the duct is used for guiding airflow to move towards the air outlet; the duct comprises a flow guide cone, a duct outer cover containing the flow guide cone and a static blade located between the flow guide cone and the duct outer cover; the motor is arranged between the air inlet and the axial flow fan, and the flow guide cone and the motor are arranged on the two opposite sides of the axial flow fan. Compared with the prior art, the hair dryer drives the small-diameter fan at a high rotating speed, so power consumption is lower, higher blowing efficiency can be obtained, and heavier leaves on a lawn, leaves in cracks and the like can be conveniently blown.

Description

[0001] This application is a divisional application of a patent application with the application number: 201510064758.6, the application date is 2015 / 02 / 06, and the invention name is hair dryer technical field [0002] The invention relates to an electric tool, especially a hair dryer. Background technique [0003] Along with the continuous expansion of urban green area, green belts in parks, highways, and public places are all over the country, and lawn trimming tools are also widely used, and hair dryers are just one of them. [0004] In current hair dryers using axial flow fans, the motor is arranged outside the duct in order to improve the efficiency of guiding the airflow. In this new type of blower, the design parameters such as the overall size of the axial flow fan, the proportional arrangement of the fan hub and the fan as a whole, and the setting of the motor speed have not fully considered the combination of blowing efficiency and power consumption, resulting in ...
