Description

Technical Field

[0001] This utility model relates to the field of electrical appliances, and in particular to a hair dryer. Background Technology

[0002] A high-speed hair dryer refers to a hair dryer in which the motor rotates at high speed, causing the fan blades to rotate rapidly, resulting in a large air volume. In existing high-speed hair dryers, the air volume enters through the air inlet, the fan blades are set inside the air tube, and the air volume is dispersed through the air tube and out through the air outlet. The air volume is relatively dispersed, which is not conducive to concentrating the air force.

[0003] There are also some existing technologies, such as... Figure 3 As shown, a wind-gathering component is installed at the external air outlet of the air duct. The air inlet of the wind-gathering component matches the air outlet of the air duct, and the diameter of the air outlet of the wind-gathering component is much smaller than the diameter of the air inlet. This causes the air force to be concentrated and blown out through the air outlet by the wind-gathering component.
