[0002] Currently, folding fans, as a portable cooling device, are widely used in daily life and work. With the advancement of technology, the design of folding fans not only focuses on portability and functionality, but also gradually incorporates more intelligent and convenient features, such as USB charging and multi-level adjustment. The addition of these features makes folding fans more practical in various scenarios such as outdoor activities, travel, and the office, thus improving the user experience.

[0003] In related technologies, the folding fans commonly found on the market mainly adopt a manual folding design, using a simple mechanical structure to unfold and fold the fan. While this design ensures portability, in actual use, it is difficult to adjust the height, angle, and direction of the fan's airflow according to needs, making it difficult to meet the personalized needs of users in different environments. At the same time, the fan cannot blow air when folded and can only be used when unfolded, which to some extent limits its applicability and flexibility and reduces the user experience.

[0004] To address the aforementioned issues, a foldable fan with USB charging capability has been designed. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] This application provides a folding fan with USB charging, which solves the problems in related technologies where general folding fans are not convenient to adjust the height, angle and direction of the airflow, and the fans cannot perform the airflow function when folded, resulting in poor applicability and flexibility.

[0031] Please see Figures 1-6 A folding fan with USB charging includes: a base 1, a first connecting rod 2, a second connecting rod 3, a hinge seat 30, a fixing frame 4, a cooling fan 5, and a drive assembly 6. The base 1 has a through hole 11 in the center. The first connecting rod 2 has two sets, which are symmetrically arranged on both sides of the base 1. One end of each set of the first connecting rod 2 is hinged to the base 1. The second connecting rod 3 has two sets, which are hinged to the end of the first connecting rod 2 away from the base 1.

[0032] The hinge seat 30 is disposed between two sets of second connecting rods 3. The two ends of the hinge seat 30 are rotatably connected to the ends of the two sets of second connecting rods 3 away from the first connecting rod 2. The fixed frame 4 is rotatably disposed on the hinge seat 30. The fixed frame 4 is located between the two sets of second connecting rods 3. Several sets of cooling fans 5 are provided. Several cooling fans 5 are rotatably disposed in the fixed frame 4. The cooling fans 5 correspond to the through holes 11. The driving component 6 is disposed on the base 1 and connected to several cooling fans 5 to drive several cooling fans 5 to rotate.

[0033] In this way, when in use, the drive component 6 can drive several cooling fans 5 to rotate simultaneously, so that the cooling fans 5 blow air outward through the through hole 11 on the base 1, thus enabling the device to achieve the air blowing function even in the folded state.

[0034] When the device needs to be unfolded, the user can adjust the height and position of the cooling fan 5 by rotating the first connecting rod 2 and the second connecting rod 3, and adjust the airflow angle of the cooling fan 5 by rotating the hinge base 30. At the same time, the airflow direction of the cooling fan 5 can be adjusted by rotating the fixed frame 4 and the hinge base 30. In this way, the user can freely adjust the height, position, airflow angle and airflow direction of the cooling fan 5, and can adjust the unfolded state of the entire device according to the needs of different environments. This not only makes the device easy to carry in the folded state, but also easy to adjust when unfolded, which is highly flexible, widely applicable and can meet the diverse needs of users, making it highly practical.

[0035] Specifically, in this embodiment, the drive component 6 includes a motor 61, a battery 62, a USB port 63, a first button 64, a first transmission component 65, and several second transmission components 66. Adjacent sets of cooling fans 5 are driven and connected through the second transmission components 66. The second transmission component 66 includes a first transmission belt 661 and two sets of first transmission wheels 662. The two sets of first transmission wheels 662 are respectively sleeved on the two adjacent sets of cooling fans 5, and the first transmission belt 661 is sleeved on the two sets of first transmission wheels 662.

[0036] The motor 61 is housed within the fixed frame 4. The first transmission component 65 includes a second transmission wheel 651, a third transmission wheel 652, and a second transmission belt 653. The second transmission wheel 651 is mounted on the motor 61, the third transmission wheel 652 is mounted on one of the cooling fans 5, and the second transmission belt 653 is sleeved on the second transmission wheel 651 and the third transmission wheel 652. The USB port 63 and the first button 64 are both mounted on the base 1. The motor 61, the USB port 63, and the first button 64 are all electrically connected to the battery 62.

[0037] When the motor 61 starts, it drives the second transmission wheel 651 to rotate, which in turn drives the third transmission wheel 652 to rotate via the second transmission belt 653. This drives one of the cooling fans 5 to rotate via the third transmission wheel 652. Then, the cooling fan 5 drives all the cooling fans 5 to rotate via the cooperation of the first transmission wheel 662 and the first transmission belt 661, thus blowing air.

[0038] Simultaneously, the motor 61 can be powered by the storage battery 62, the start and stop of the motor 61 can be controlled by the first button 64, and the storage battery can be charged through the USB port 63, thereby enabling the device to be used without power supply limitations and enhancing the flexibility of the device.

[0039] It should be noted that the use of a battery 62, a USB port 63, and a first button 64 to power and start / stop the motor 61 is existing technology, and the aforementioned components are commercially available devices. Furthermore, this application does not improve how the motor 61 is powered, charged, and started / stopped, so it will not be described in detail here.

[0040] The storage battery 62 is located inside the base 1;

[0041] This allows the battery 62 to add counterweight to the base 1, thereby lowering the center of gravity of the device and ensuring its stability when placed after deployment.

[0042] Furthermore, in this embodiment, the fixed frame 4 is provided with an LED light strip 7, the LED light strip 7 is electrically connected to the storage battery 62, and the base 1 is provided with a second button 8 that is electrically connected to the LED light strip 7;

[0043] In this way, when the user unfolds the device, they can control the LED light strip 7 to switch on and off via the second button 8, so that the device can be used as a desk lamp for lighting. The device can also dissipate heat and cool down while providing lighting for the user, thus enhancing the applicability of the device.

[0044] It should be noted that the second button 8 and the LED light strip 7 in this application are also prior art and can be purchased on the market. Furthermore, this application does not make any improvements to the second button 8 and the LED light strip 7 themselves, so they will not be described in detail here.

[0045] Furthermore, both the first button 64 and the second button 8 are located on the side of the base 1 away from the first connecting rod 2. The ends of the two sets of first connecting rods 2 away from the base 1 are fixedly connected by a connecting plate 9, which corresponds to the first button 64 and the second button 8.

[0046] In this way, the connecting plate 9 not only enhances the stability of the connection between the two sets of first connecting rods 2 and the two sets of second connecting rods 3, thus strengthening the structural strength of the device, but also covers the first button 64 and the second button 8 when the device is folded. This prevents the user from accidentally pressing the first button 64 and the second button 8 when the device is folded, thus ensuring the safety of the device and making it convenient to use.

[0047] Preferably, the fixing frame 4 is provided with a protective cover 10, the protective cover 10 is located inside the through hole 11, and the plurality of cooling fans 5 are all located inside the protective cover 10;

[0048] This allows the cooling fan 5 to be shielded and protected by the protective cover 10, thereby enhancing the safety of the device and making it highly practical.
