Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of handheld fans, in particular, to a portable reinforced handheld fan. BACKGROUND

[0002] The information provided in this section is for the purpose of generally presenting the context of the application. The work of the now named inventors, to the extent the descriptions are concerned with, neither explicitly nor implicitly, are considered prior art with respect to the present application.

[0003] In the hot summer, people used to cool down by fans and the like. With the improvement of people's living standards, portable handheld fans have become a frequently used household item for people going out. Nowadays, handheld fans have become an indispensable 3C electronic product in people's summer life, and various handheld fans are hot-selling on the market.

[0004] A small handheld refrigeration fan disclosed in a Chinese patent with the publication number CN222457825U includes a handle, an outer cover assembly, and a fixed outer cover assembly. The outer cover assembly and the fixed outer cover assembly are threadedly connected and rotatably arranged at the top of the handle. The outer wall of the handle is slidably sleeved with an outer sleeve. The outer wall of the bottom end of the handle is provided with a receiving groove. Each group of receiving grooves is rotatably provided with a support plate. The outer cover assembly includes an outer ring connected with the fixed outer cover assembly. The product protects the fan in a non-use state by the outer cover assembly to prevent data lines, key pendants, and other objects from entering during carrying in a bag or to prevent the situation of long hair of girls invading and entangling, thereby further improving the practicality of the handheld fan. Meanwhile, the foldable and storable support plate makes the fan more convenient to hold or stand on the desktop without worrying about the loss of the base.

[0005] After long-term research, we found that many consumers have higher requirements for the firmness of handheld fans. Because it is easy to drop the small fan when holding it, many handheld fans are "not allowed to fall", and are easily damaged after falling a few times, especially the fan cover part is seriously deformed and damaged or even scattered, which easily causes consumers to be dissatisfied and affects the long-term stable and normal use of consumers.

[0006] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present application, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art.
