[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] 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.

[0025] Example:

[0026] Please see Figure 1 - Figure 4 A portable mini fan with multi-level limiting placement in this embodiment includes a front cover 1, a rear cover 2 fixedly connected to the outer surface of the front cover 1, damping shafts 3 rotatably connected to both sides of the front cover 1 and the rear cover 2, a limiting ring 4 fixedly connected to the other end of the damping shaft 3, and a bracket 5 fixedly connected to the other end of the limiting ring 4. The outer surfaces of the two limiting rings 4 are in close contact with the outer surfaces of the front cover 1 and the rear cover 2 to stabilize the rotation of the bracket 5.

[0027] The bracket 5 has a narrow band fixing groove 6 inside, a wide band fixing groove 7 inside, and a barb structure 8 on the outer surface of the bracket 5.

[0028] The bracket 5 is manually rotated around the axis of the damping shaft 3, so that the damping shaft 3 rotates inside the front cover 1 and the rear cover 2, so that the bracket 5 and the fan body can form different angles. Every five degrees of rotation of the bracket 5, there will be a locking point. At the same time, the limiting ring 4 keeps the bracket 5 and the body relatively close, so it can be stably positioned at this angle. At this time, the product can be placed on a flat object surface or table, so that the bracket 5 can provide stable support for the product. When rotated to different angles, the air blowing direction of the fan will change. The air blowing direction of the fan changes by the same angle as the bracket 5 rotates. This allows the user to adjust the air blowing direction of the fan when the fan is not in use, so that the user can more conveniently enjoy the coolness and comfort of the fan.

[0029] At this point, through the narrow strap fixing groove 6 and the bracket 5, two hook structures of different sizes are designed in the bracket 5. The narrow strap fixing groove 6 is designed to be used on a narrower strap similar to a key strap, while the wide strap fixing groove 7 is designed to be used to hook the product onto a wider fabric strap of a travel bag or handbag. After the fan is hooked onto the travel bag strap or handbag fabric, it will not easily fall off because the hook structure has a barbed structure 8, making the small fan easy to carry by hook and not easy to lose.

[0030] The upper surface of the rear cover 2 is fixedly connected to the rear fan cover 9, the outer surface of the rear fan cover 9 is fixedly connected to the connecting frame 10, the outer surface of the connecting frame 10 is fixedly connected to the front fan cover 11, the interior of the front cover 1 and the rear cover 2 is equipped with a lithium battery 12, which provides power to the entire device. The outer surface of the front cover 1 is equipped with a button 13, which can quickly start the device and increase the wind speed. The lower surface of the connecting frame 10 is fixedly connected to the upper surface of the front cover 1, and the rear fan cover 9 and the front fan cover 11 are fixed by the connecting frame 10.

[0031] The front cover 1 and the rear cover 2 are combined to install the internal power supply structure, including the lithium battery 12, which powers the entire fan. The design of the rear fan cover 9 and the connecting frame 10 can protect the user from being accidentally injured by the internal fan blades. The connecting frame 10 facilitates the installation of the rear fan cover 9 and the front fan cover 11. Pressing the button 13 can start the fan.

[0032] The working principle of the above embodiment is as follows: During use, the bracket 5 is manually rotated around the axis of the damping shaft 3, causing the damping shaft 3 to rotate inside the front cover 1 and the rear cover 2, thus creating different angles between the bracket 5 and the fan body. Every five degrees of rotation of the bracket 5 creates a locking point, and the limiting ring 4 ensures that the bracket 5 and the main body are tightly fitted together, thus securing it at this angle. At this time, the product can be placed on a flat surface or table, allowing the bracket 5 to provide stable support. When rotated to different angles, the fan's airflow direction changes. The angle by which the bracket 5 rotates corresponds to the angle by which the fan's airflow direction changes, allowing for easy adjustment of the fan's airflow direction when the fan is not in use, making it more convenient for the user to enjoy the coolness and comfort of the fan. The combination of the front cover 1 and the rear cover 2... The internal power supply structure includes a lithium battery 12, which powers the entire fan. A narrow mounting slot 6 and a bracket 5 are used. The bracket 5 features two hooks of different sizes. The narrow mounting slot 6 is designed for use on narrower straps, similar to keychains, while the wide mounting slot 7 is designed for attaching the product to wider straps of travel bags or handbags. Once the fan is hooked onto the travel bag strap or handbag, the hook structure has a barbed hook 8, preventing it from easily falling off, making the small fan easy to carry and less likely to be lost. The rear fan cover 9 and connecting frame 10 provide protection for the user, preventing accidental injury from the internal fan blades. The connecting frame 10 facilitates the installation of the rear fan cover 9 and the front fan cover 11. Pressing the button 13 starts the fan.

[0033] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
