Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 A multi-purpose portable fan includes a fan body 1, with folding legs 2 connected to the bottom end face of the fan body 1. The folding legs 2 include a first leg 21 and a second leg 23. One end of the first leg 21 and the second leg 23 are hinged to each other through a hinge mechanism. The first leg 21 and the second leg 23 can be unfolded or folded relative to each other with the hinge mechanism as the axis.

[0023] The folding support leg 2 is connected to the bottom surface of the fan body 1 via a limiting mechanism. The limiting mechanism includes a first limiting mechanism and a clearance mechanism that cooperates with the first limiting mechanism to achieve limiting and unlocking. The first limiting mechanism includes a shaped shaft 11 disposed on the bottom surface of the fan body 1, a shaped bushing 232 disposed at the pivot of the hinge mechanism of the folding support leg 2, and a bolt 27 for connecting the shaped bushing 232 and the shaped shaft 11. The clearance mechanism includes a clearance member receiving cavity 233 disposed at the end of the shaped bushing 232 away from the fan body 1, and a clearance member receiving cavity 233 disposed at the end of the shaped bushing 232 away from the fan body 1. The elastic relief member 24 is located within the cavity 233, and a gasket 25 is placed at the opening of the cavity 233. The bolt 27 passes through the gasket 25 and the elastic relief member 24. The elastic relief member 24 can elastically deform under force. When the first leg 21 and the second leg 23 are in the folded state, the irregular bushing 232 is fitted around the irregular shaft 11 in the circumferential direction. The irregular contour is matched to achieve a limit, so that the first leg 21 and the second leg 23 will not rotate relative to each other, thereby locking the folding leg 2 in the folded state to the fan body. 1. When the first support leg 21 and the second support leg need to be unfolded relative to each other to use the folding support leg 2 for stable support of the fan body 1, so that the fan body 1 can be placed on the table, the second support leg 23 can be pulled by external force to move the second support leg 23 away from the fan body 1. At this time, the elastic relief member 24 located in the relief member receiving cavity 233 is compressed and deformed. The thinned elastic relief member 24 can make way for the irregular bushing 232, so that the irregular bushing 232 is removed from the axial range of the irregular shaft 11, thereby making the irregular bushing 232... The locking state between 232 and the irregular shaft 11 is released. The limiting mechanism also includes a second limiting mechanism. The second limiting mechanism includes a limiting groove 212 disposed on the upper surface of the folding support leg 2 and a limiting protrusion 12 disposed on the bottom end face of the fan body 1. The limiting protrusion 12 is placed in the limiting groove 212 and is slidably connected with the limiting groove 212. The cooperation between the limiting protrusion 12 and the limiting groove 212 can limit the maximum unfolding angle of the first support leg 21 and the second support leg 23, which is beneficial to improving the overall appearance and cleanliness of the product during use.

[0024] The pad 25 is a magnetic component. Using the pad 25 with magnetic attraction, the fan body 1 can be attached to a metal object, increasing the usage scenarios of the fan body.

[0025] The hinge mechanism includes a bushing 211 disposed on the first support leg 21 and a rotating shaft 231 disposed on the second support leg 23. The bushing 211 is sleeved around the rotating shaft 231 in the circumferential direction. A damping ring 22 is sandwiched between the first support leg 21 and the second support leg 23. The damping ring 22 plays a role in increasing the damping effect when the first support leg 21 and the second support leg 23 rotate relative to each other, so that the first support leg 21 and the second support leg 23 can be relatively positioned after the external force is removed.

[0026] The bottom end face of the first support leg 21 and the bottom end face of the second support leg 23 are flush. Anti-slip pads 26 are provided on the bottom end face of the first support leg 21 and the bottom end face of the second support leg 23. This technical solution can effectively improve the stability of the folding support leg 2 supporting the fan body 1.

[0027] In summary, this utility model allows the folding support leg 2 to support the fan body 1 when unfolded, enabling it to be stably placed on a flat surface. When folded, the folding support leg 2 can be hidden and stored on the fan body 1, resulting in a simple appearance and making it convenient for users to carry and use. The folding support leg 2 is also equipped with a magnetic component, allowing the fan body 1 to be attached to objects with magnetic attraction. Therefore, it has diverse application scenarios, practical functions, and effectively improves the product's cost-effectiveness and practicality.
