Description

Technical Field

[0001] The utility model relates to the field of hair dryer equipment structure, in particular to a blower with press-folding feedback. Background Art

[0002] A hair dryer is a small household appliance that is mainly used to quickly dry wet hair and reduce the time required for natural drying. Its basic principle is to generate heat through a built-in electric heating element, while the internal motor drives the fan to rotate, forming a strong stream of hot or cold air. This wind is blown out through the air collecting nozzle at the front end of the hair dryer and acts directly on the wet hair, causing the moisture to evaporate quickly, thereby achieving the effect of quick drying hair. It is one of the indispensable items in modern people's daily life.

[0003] Folding hair dryers are distinguished by their foldable design, making them convenient for storage and portability when not in use. This foldable design significantly reduces their size and weight, making them easy to carry for travel, business trips, and everyday life without taking up too much space. They are particularly suitable for those who frequently carry a hair dryer, such as travelers, students, and office workers. Furthermore, their portability makes them suitable for specific occasions, such as camping and use at the gym.

[0004] A conventional folding hair dryer is composed of a hair dryer and a handle, which are hinged at one end of the hair dryer body and the handle to achieve the folding function. For example, a household hair dryer described in the patent document with the announcement number CN208048267U realizes the above function. However, for hair dryers like this, the hinge is usually achieved by simply adding a rotating shaft between the hair dryer body and the handle. In a short period of time, the handle can be folded at any angle on the hair dryer and fixed, thereby realizing the function of the hair dryer. However, as the use time increases, the rotating shaft may gradually lose its fixing ability due to wear or loosening, resulting in the handle being unable to stably maintain the angle required by the user, which may affect the comfort and convenience of the user when operating the hair dryer. In order to improve the user experience, it is possible to consider using more durable hinged materials or designs to enhance its long-term stability.

[0005] Therefore, there is an urgent need to provide a fan with press-folding feedback to solve the above technical problems. Summary of the Invention

[0006] In response to the problems in the related art, the utility model proposes a fan with press-folding feedback, which can be fixed after each folding and has a folding feedback effect. At the same time, it will not loosen after multiple foldings.
