Description

TECHNICAL FIELD

[0001] The utility model provides a rotatable air nozzle's hair drier belongs to hairdressing appliance field. BACKGROUND

[0002] In the development history of hair dryers, traditional hair dryers mainly focus on realizing basic drying function. The air nozzle of early hair dryers is usually of fixed structure, and after being connected with the main body of the hair dryer, the air outlet direction thereof cannot be adjusted. Such fixed air nozzle design has many inconveniences in actual use. For example, when the user needs to dry different parts of the hair, especially the side and back of the head, it is often necessary to frequently move the entire hair dryer body to change the air direction, which not only is troublesome to operate, but also is difficult to accurately control the air direction, easily leading to uneven drying of the hair, overheat in some areas while still damp in other areas, affecting the drying efficiency and use experience.

[0003] With the increasing diversification of hairdressing needs and the continuous improvement of product convenience requirements, hair dryer technology has gradually improved. Some hair dryers have begun to innovate in air nozzle design, and air nozzles that can adjust the angle within a certain range have appeared, but these air nozzles mostly have limited adjustment angle, not smooth enough adjustment process, and complex structure that is easy to damage, etc. For example, some adjustable air nozzles use simple hinge structure, although they can realize rotation within a certain angle, but they are prone to jamming during rotation, and the hinge is severely worn after long-term use, affecting the stability and service life of the air nozzle.

[0004] In addition, in terms of hair styling, professional stylists and ordinary consumers have an increasingly urgent need to accurately control the air direction to create different hair styling effects. Whether it is to blow out fluffy hair roots, smooth straight hair or curly styling, the hair dryer air nozzle needs to be able to flexibly and stably change the air outlet direction to cooperate with different styling methods. However, the existing air nozzle technology cannot fully meet this demand, and cannot realize omnidirectional and multi-angle free twisting while ensuring structural reliability, thereby limiting the further application and development of hair dryers in the hair styling field.
