Technical Field

[0001] This utility model relates to the technical field of hair dryers, and more particularly to a nozzle structure for a hair dryer. Background Technology

[0002] Hair dryers are primarily used for drying and styling hair, but can also be used for other drying and grooming purposes. They work by drawing in outside air, heating it, and then blowing it out. Hair dryers typically have a nozzle at the air outlet to concentrate the airflow before blowing it out.

[0003] However, some traditional air nozzles are quite noisy or have significant loss of air pressure and air speed. Utility Model Content

[0032] The connecting area 21 is an arc-shaped line. The first guide surface assembly 23 extends from the bottom of the inner guide fluid 2 toward the arc-shaped line.

The third guide surface assembly 25 and the fourth guide surface assembly 26 connect the first guide surface assembly 23 and the second guide surface assembly 24. The connecting area 21 is a plane. The first guide surface assembly 23 extends from the bottom of the inner guide fluid 2 toward the left side of the plane, and the second guide surface assembly 24 extends from the bottom of the inner guide fluid 2 toward the right side of the plane. A third guide surface assembly 25 and a fourth guide surface assembly 26 are respectively disposed between the first guide surface assembly 23 and the second guide surface assembly 24, extending from the bottom of the inner guide fluid 2 toward the front and rear sides of the plane.

[0034] Specifically, in this embodiment, the guide surface assembly includes one or more smooth curved surfaces. Preferably, the guide surface assembly is a single smooth curved surface. "Approaching extension" means that the distance between the first guide surface assembly 23 and the second guide surface assembly 24 gradually decreases along the direction from the air inlet to the air outlet. The "plane" is formed by bending a rounded rectangle along a certain arc; the plane can be an arc-shaped plane or a horizontal plane; the plane has four sides, one pair of which are short sides; the other two opposite sides are parallel extending long sides, which are two parallel long arcs.
