Description

Technical Field

[0001] This application belongs to the field of fan technology, and in particular relates to a portable lithium-ion outdoor fan. Background Technology

[0002] With the increasing number of outdoor activities, people inevitably encounter times when they go out without fans or air conditioning. In order to enable people to use fans at any time even when they are outdoors, portable fans have become an important tool for people to relax outdoors. They serve as a quick cooling tool for people going out in the hot summer, thus relieving heat and making people feel cool.

[0003] Currently, most portable fans are one-piece designs with built-in rechargeable batteries, allowing them to be taken outdoors after a full charge. However, the battery capacity of existing portable fans is limited, requiring recharging once the battery is depleted, which is insufficient for extended outdoor use. Improvements are needed to address this issue. Utility Model Content

[0004] The purpose of this application is to address the aforementioned technical problems by providing a portable lithium-ion outdoor fan that can be easily transported and improved in terms of convenience by folding the support base and legs.

[0010] The fan assembly consists of a fan cover, motor, and fan blades. The motor powers the fan to rotate and blow air. There are two fan covers, front and rear, connected by screws and other fasteners. The motor is mounted on the rear fan cover. The bracket assembly is connected to the fan cover. The legs are movably connected to the support base. The sliding part and sliding groove use a sliding hinge structure. When the sliding part moves to one end of the sliding groove, the support base and telescopic base are in a retracted state, and the plug-in part is inserted into the plug-in groove, achieving a folded state for the support base and legs, facilitating the overall movement and transportation of the fan. When the sliding part is in the sliding groove and moved to the other end, the plug-in part is pulled out of the plug-in groove, and then the support base rotates around the sliding part. The movement causes the contact surface to abut against the insertion part, forming an angle between the support leg and the support base. When the support base is in support, it is in an extended state with the telescopic base, increasing the support area of ​​the support base and further improving its support performance. This allows the fan assembly to be supported on the placement surface. The battery plug is used to insert a lithium battery pack.
