[0029] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0030] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0031] like Figure 1As shown, a magnetic wireless charging and cooling handheld folding fan includes a fan body 1. The fan body 1 adopts a folding design and includes an upper shell 2 and a lower shell 3. The upper shell 2 serves as the fan head, and the lower shell 3 serves as the handle. A connecting tube 5 is installed on the lower rear side of the upper shell 2, and a connecting tube 6 is installed on the upper rear side of the lower shell 3. The connecting tube 6 is rotatably connected to the inside of the connecting tube 5 via a pivot. The pivot can rotate flexibly at multiple angles. When the fan is in use, the upper shell 2 and the lower shell 3 unfold to a suitable angle for convenient handheld operation. When not in use, the upper shell 2 can be tightly folded into the lower shell 3, greatly reducing the product size and making it easy to store and carry. It can be easily placed in a pocket or backpack without any burden. A fan motor 16 is installed inside the upper shell 2, and a fan blade 17 is installed at the output end of the fan motor 16. The fan motor 16 is electrically connected to a polymer lithium battery 14. Rotatable brackets 4 are installed on both sides of the rear end of the lower shell 3. The brackets 4 are U-shaped, and rotating the brackets 4 allows the fan to stand upright on a table for operation.

[0032] The upper shell 2 and lower shell 3 are made of high-strength, lightweight aluminum alloy. The upper shell 2 has a circular mesh structure, which ensures the product's sturdiness and durability while reducing the overall weight and making it easy for users to hold. The outer shell is made of environmentally friendly, wear-resistant plastic material, which has a good feel and appearance.

[0033] The magnetic attachment 7 is located inside the lower part of the lower housing 3. Magnetic attachment 7 uses a high-performance neodymium iron boron magnet, possessing strong magnetic force to ensure stable adhesion between the fan and the phone. It is also resistant to demagnetization due to external environmental factors. Magnetic attachment 7 can firmly adhere to phones or phone cases with magnetic attachment capabilities, allowing the fan to be stably fixed to the back of the phone. When users want to free their hands to watch videos, browse short videos, or perform other phone operations, the fan's magnetic function comes into play, eliminating the need for additional handheld operation and providing a convenient user experience.

[0034] The wireless charging structure 8 is located inside the lower housing 3. The wireless charging structure 8 includes a wireless charging magnetic coil 12, a wireless charging drive module 13, a polymer lithium battery 14, a main control PCBA 15, and related control circuits. The wireless charging drive module 13 is electrically connected to the wireless charging magnetic coil 12, the polymer lithium battery 14, and the main control PCBA 15. When a mobile phone with wireless charging function is attached to the magnetic part of the fan, the wireless charging module can convert the electrical energy of the fan power device into magnetic field energy and wirelessly charge the mobile phone through the principle of electromagnetic induction, solving the problem of insufficient mobile phone battery for users outdoors. The polymer lithium battery 14 is a high-performance rechargeable battery with a reasonably designed battery capacity. After a full charge, it can meet the user's long-term use needs, providing stable power support for the fan's airflow, cooling function, and wireless charging of mobile phones.

[0035] The cooling structure 9 includes a semiconductor cooling chip 10, which is located inside the upper housing 2. A cold-conducting metal sheet 11 is installed at the front end of the upper housing 2. The semiconductor cooling chip 10 uses high-quality bismuth telluride semiconductor material to ensure cooling effect. When the semiconductor is energized, it will generate the Peltier effect, that is, when current passes through a couple composed of two different semiconductor materials, heat absorption and heat release will occur at the two ends of the couple, respectively. The cooling structure 9 utilizes this principle and, through reasonable circuit design, generates a low temperature on one side of the module to provide a cooling effect for the user. To ensure the stable operation of the semiconductor cooling structure 9, the fan is also designed with corresponding heat dissipation and insulation structures. A high-efficiency heat sink and a cooling fan are installed at the heat-generating end of the cooling structure 9 to ensure heat dissipation efficiency and dissipate the generated heat in a timely manner, avoiding affecting the cooling effect and the normal operation of other fan components. At the same time, a heat insulation layer is set between the cooling module and other parts of the fan, which has excellent heat insulation performance and lightweight characteristics, preventing low temperature from being conducted to other unnecessary parts of the fan, ensuring user safety and comfort.

[0036] A control button 18 is installed on one side of the lower housing 3. The control button 18 allows for multiple speed adjustments of the fan. A TYPE-C charging port is installed on the other side of the lower housing 3. The fan has multiple wind speed adjustment functions, and users can easily switch between different wind speeds through the control button 18, from a gentle breeze to a strong wind, to meet the user's choice of wind speed in different scenarios and personal needs. The product is equipped with a common USB charging port 19, which allows users to recharge the fan anytime and anywhere using power banks, computers and other devices.

[0037] Detailed assembly process:

[0038] First, install the fan motor 16 inside the upper housing 2. Then, fix the fan blade 17 on the output shaft of the fan motor 16 to ensure that the fan blade 17 rotates flexibly. Next, connect the lower housing 3 and the upper housing 2 through a rotating shaft and install the relevant fixing parts to ensure that the rotating shaft rotates smoothly and the angle is adjustable.

[0039] Install the wireless charging magnetic coil 12 inside the lower housing 3 according to the designed position, connect the control circuit and power line, and then fix the magnetic component 7 at the bottom of the lower housing 3 to ensure that the magnetic position is accurate and firm.

[0040] Install the cooling structure 9 in the corresponding position on the fan, connect the circuit, and ensure that the current can correctly pass through the semiconductor material to generate a cooling effect. Install a heat sink and a cooling fan on the heat-generating end of the cooling structure 9, and connect the power line of the cooling fan. Finally, install an aerogel insulation layer between the cooling module and other components.

[0041] Control buttons 18, used to control the fan switch, wind speed adjustment, and cooling function switch, are installed on the lower housing 3 to ensure sensitive button operation. At the same time, the USB charging port 19 is installed in a suitable position on the lower housing 3 and connected to the internal circuit to ensure normal charging function.

[0042] In actual use, turn on the fan control button 18, select the appropriate fan speed setting using the fan speed adjustment button 18, and the fan will start blowing air. In hot weather, users can hold the fan to enjoy the coolness.

[0043] When a user needs to free their hands to use their phone and charge it, they simply bring the fan's magnetic attachment 7 close to a phone or phone case with magnetic attraction, and the fan will automatically attach to the back of the phone. At this time, the wireless charging structure 8 will automatically detect the phone and begin wireless charging, allowing the user to freely operate the phone, such as watching videos or browsing short videos.

[0044] In particularly hot environments, users can press the cooling function control button 18, activating the semiconductor cooling structure 9 to generate a low temperature. Users can then place the fan's cooling conduction metal plate 11 close to their skin, such as on the forehead or neck, for a comfortable cooling experience. While using the cooling function, the fan's airflow function can be turned on simultaneously as needed to enhance the cooling sensation.

[0045] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
