[0036] In this utility model, the cable storage structure 9 includes a baffle 91 and a friction block 92. The baffle 91 and the friction block 92 are fixedly connected. The end of the baffle 91 is fixedly connected to two buckles. The baffle 91 is slidably inserted into the bottom of the base body 4 and connected to the base body 4 through buckles. The cable storage structure 9 can facilitate users to store the cables required for charging. When storing or using the cable, the baffle 91 can be slid out. The friction block 92 on the baffle 91 can increase the friction between the user and the baffle 91. After the baffle 91 is pulled out, the cable can be stored in the cable storage space reserved inside the base body 4, or the cable can be taken out from the space. After the cable is stored or taken out, the baffle 91 can be slidably inserted back into the bottom of the base body 4 using the buckles, and the desktop fan can be used normally.

[0037] In this utility model, a rubber pad 10 is provided at the bottom of the base body 4. The rubber pad 10 is located on both sides of the bottom of the base body 4 and is fixedly connected to the base body 4. The rubber pad 10 at the bottom of the base body 4 enhances the anti-slip properties of the device, ensuring safe use and a clean desktop.

[0038] In this utility model, there are three guide grooves 13 that are equidistantly distributed on the positioning ring 11, three guide blocks 14 that are equidistantly distributed on the air outlet cover 12, three locking blocks 17 that are equidistantly distributed on the air guide cover 15, and three sliding grooves 19 that are equidistantly distributed on the air inlet cover 18. The three equally distributed air guide grooves 13, air guide blocks 14, locking blocks 17, and sliding grooves 19 can make the fan body more stable during installation.

[0039] In this utility model, the slide groove 19 is L-shaped and opens inside the air inlet cover 18. The L-shaped slide groove 19 allows the locking block 17 to be inserted into the depth of the slide groove 19 more quickly, thus completing the installation between the air inlet cover 18 and the air guide cover 15.

[0040] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0041] In this implementation scheme: the various structures of the fan body 1 adopt detachable connection methods such as snap-fit. During installation, the guide block 14 on the air outlet cover 12 slides along the direction of the guide groove 13 on the positioning ring 11, thereby connecting the positioning ring 11 and the air outlet cover 12 through snap-fit. Then, the air outlet cover 12 is inserted into the front side of the guide cover 15 to install the data display structure 7. The guide cover 15 can help guide air to flow more smoothly into the fan blade area. By optimizing the direction and speed distribution of airflow, airflow turbulence can be reduced, allowing air to be drawn in more efficiently. The display motherboard 71 and the fixing sleeve 72 are respectively inserted into the guide cover 15. Then, the mounting sleeve 73 is inserted into the fixing sleeve 72, and the mounting sleeve 73 and the guide cover 15 are fixed by bolts. Finally, the display screen 71 is fixed to the mounting sleeve 73 with snap-fit ​​to complete the installation of the data display structure 7. The data display structure 7 can provide real-time feedback on operating parameters, improving the intuitiveness of operation. The cable connecting the data display structure 7 and the control structure 8 runs along the base body 4, the limit groove 5, and the ring. The cavity formed by the toothed block 16 and the air guide 15 is connected to the data display structure 7. When installing the air inlet shroud 18, first install the electric fan blades on the rear side of the air guide 15, then slide the locking block 17 on the rear side of the air guide 15 into the groove 19 on the air inlet shroud 18 and rotate the air inlet shroud 18 by a certain angle to complete the installation of the fan body 1. The two sides of the fan body 1 are respectively inserted into a rotating block 2. The rotating block 2 is rotatably connected to the base body 4, so that the fan body 1 can adjust the angle with the rotating block 2 as the center to achieve multi-angle air outlet. The buckle connection of the cover plate 6 simplifies maintenance. The control structure 8 is installed on the front. The base 41 and the rear base 42, and the front base 41 and the rear base 42 are connected by bolts. The angle positioning block 43 inside the base body 4 can cooperate with the limit block 3 to keep the rotation angle of the fan body 1 within a certain range, preventing excessive rotation from damaging the internal cables. The charging interface 84 on the control motherboard 82 supports charging of the battery 83. The power supply interface 85 on the control motherboard 82 supports reverse power supply, which can provide emergency charging support for mobile phones or other USB devices when necessary, further enhancing the practicality and flexibility of the product. The control switch 81 on the control motherboard 82 is used to control... The rotation of the fan blades inside the air guide shroud 15 and the cable storage structure 9 allow users to easily store the charging cables. When storing or using the cable, slide out the baffle 91. The friction block 92 on the baffle 91 increases the friction between the user and the baffle 91. After the baffle 91 is pulled out, the cable can be stored in the cable storage space inside the base body 4, or the cable can be taken out of the space. After the cable is stored or taken out, the baffle 91 can be re-inserted into the base body 4 using the buckle. The desktop fan can then be used normally. The rubber pad 10 at the bottom of the base body 4 enhances the anti-slip properties of the device, ensuring safe use and a clean desktop.
