Description

[Technical Field]

[0001] This utility model relates to the technical field of portable small fan products, and in particular to a highly practical portable multi-functional fan that can be used as a mobile phone support. [Background Technology]

[0002] Portable fans have become increasingly popular among consumers, allowing them to enjoy coolness anytime, anywhere. In recent years, a wide variety of portable fan products with different shapes and styles have emerged, giving users more choices.

[0003] Currently, there are various types of portable fans on the market, including handheld fans for users to hold in their hands and tabletop fans for users to place on a table. However, in actual use, handheld fans cannot be used independently on a table. When placed on a table, they need to be supported by a stand to stand upright. While tabletop fans can be placed directly on a table, they are usually only suitable for tabletop use and cannot be held by hand. Furthermore, holding a tabletop fan by hand can easily block the fan's air inlet and outlet, affecting airflow. Each type of fan has its own limitations.

[0004] To make it easier to stand on a table, some portable fans come with adjustable support rods. However, these rods are not very stable or reliable, and they cannot provide adequate support. They are also easily damaged by external forces, affecting normal use.

[0005] For example, utility model patent application number CN202222287611.1, entitled "A Portable Fan," specifically discloses a portable fan comprising: a main body including an air outlet area and a functional area, the functional area having a receiving slot, the functional area being usable for handheld use; a fan assembly disposed in the air outlet area, the air outlet area having an air inlet and an air outlet communicating with the fan assembly; and a support portion pivotally connected to the functional area, the support portion being pivotally embedded into or pivotally detached from the receiving slot to support the main body. By providing the support portion, the portable fan can be used both handheld and tabletop, allowing users to apply the portable fan to various scenarios in life and work, thus improving the utilization rate of the portable fan.

[0006] The specific implementation

[0030] section discloses that "the receiving groove 124 includes a pivot groove 1242, the pivot groove 1242 is provided with a pivot hole 12421 and a stop part 12422, the support part 5 is provided with a pivot rod 53 and a stop part 54, the pivot rod 53 is received in the pivot hole 12421 so that the support part 5 is pivotally connected to the pivot groove 1242. During the pivoting process of the support part 5, the stop part 54 abuts against the stop part 12422 so that the support part 5 is positioned at that angle." The use of a relatively weak stop part structure to limit the angle of the entire product, and its location on the rear side of the product, results in poor stability in actual use.

[0007] Therefore, further improvements and enhancements are needed based on existing technologies. [Utility Model Content]
