[0023] In view of the technical problems described in the background art, such as Figure 1-5As shown, a novel waist-mounted fan is provided, comprising: a housing 1, wherein the housing 1 has an installation space, and at least one hook 2 is provided on the outer wall of the housing 1; an air outlet 3 is provided on the upper end face of the housing 1, and an air inlet 4 is provided on the lower end face of the housing 1; a motor 5, wherein the motor 5 is installed inside the housing 1, and a fan blade 6 is installed on the rotating end of the motor 5, the fan blade 6 being close to the air outlet 3; a first battery cell 7, wherein the first battery cell 7 is disposed inside the housing 1; and a first control circuit board 8, wherein the first control circuit board 8 is disposed inside the housing 1, and the first control circuit board 8 is connected to the first battery cell 7. The motor 5 is electrically connected, and the first control circuit board 8 is provided with a charging interface 18; the second battery cell 9 is disposed inside the housing 1; the second control circuit board 10 is disposed inside the housing 1 and is electrically connected to the second battery cell 9; the cable reel 11 is disposed inside the housing 1, and the output / input line 12 is wound on the cable reel 11. The output / input line 12 is electrically connected to the second control circuit board 10, and the charging end of the output / input line 12 is led out and fixed on the outer wall of the housing 1.

[0024] This novel waist-mounted fan mainly consists of a housing 1, a motor 5, a first battery cell 7, a first control circuit board 8, a second battery cell 9, a second control circuit board 10, a winding reel 11, and an air guide component 14. These components work together to achieve the waist-mounted fan's portability, long battery life, additional charging capability, and efficient cooling.

[0025] The housing 1 is made of high-strength, lightweight plastic material, such as ABS engineering plastic, to ensure that the overall weight of the fan is light and easy to carry, while also having a certain degree of impact resistance. The housing 1 is generally in the shape of a flat rectangular box, and its size is designed according to the layout of the internal components and actual usage requirements.

[0026] The outer wall of the housing 1 has at least one hook 2, preferably two hooks 2, located on both sides of the housing 1. The hooks 2 can be fixed to the housing 1 by assembly. One hook 2 allows the user to hang the fan on their belt, while the other hook 2 is used to hold clothing, preventing clothing from obstructing the air inlet 4. The upper surface of the housing 1 has an air outlet 3, which is circular or other shapes. The lower surface has an air inlet 4, which can be designed as a grille structure to ensure sufficient airflow and prevent foreign objects from entering.

[0027] A DC brushless motor 5 can be selected, which has advantages such as high efficiency, low noise, and long life. The size of the motor 5 is selected according to the internal space of the housing 1 and the power requirements of the fan. The motor 5 is fixed to the preset installation position inside the housing 1 with bolts to ensure that the motor 5 is stable and reliable during operation. The fan blade 6 is fixed to the rotating end of the motor 5, ensuring that the fan blade 6 is tightly connected to the motor 5 and can rotate synchronously when the motor 5 is running.

[0028] Both the first battery cell 7 and the second battery cell 9 are lithium-ion batteries, which have advantages such as high energy density and good charge / discharge performance. The capacity of the battery cells is determined according to the power of the fan and the required usage time. The first battery cell 7 and the second battery cell 9 are respectively installed in preset mounting positions inside the housing 1 and fixed by clips or glue. The electrodes of the battery cells are connected to the corresponding control circuit board through wires to ensure circuit continuity.

[0029] The first control circuit board 8 is mainly responsible for controlling the operation of the motor 5, and, in conjunction with the buttons, adjusting the speed of the motor 5 and controlling the charging and discharging of the first battery cell 7. The second control circuit board 10 is used to control the charging and discharging function of the second battery cell 9.

[0030] Installation and Connection: The first control circuit board 8 and the second control circuit board 10 are respectively installed in corresponding spaces inside the housing 1 and fixed with screws. The first control circuit board 8 is electrically connected to the first battery cell 7 and the motor 5 through wires, and the second control circuit board 10 is electrically connected to the second battery cell 9 through wires.

[0031] The first control circuit board 8 is provided with a charging interface 18. The charging interface adopts the common Micro-USB and / or Type-C interface. Preferably, the charging interface 18 includes a Micro-USB interface and a Type-C interface. When the first battery cell 7 is out of power, the first battery cell 7 can be charged by connecting the output / input line 12 through the Type-C interface or by connecting the power supply through the Micro-USB interface.

[0032] The reel 11 is disc-shaped and installed inside the housing 1. The reel 11 is prior art and is used to stretch and retract the output / input cable 12. Under the action of external force, the output / input cable 12 is pulled out from the reel 11, and after the external force is removed, the output / input cable 12 is retracted onto the reel 11.

[0033] One end of the output / input line 12 is electrically connected to the second control circuit board 10, and the other end, the charging terminal, is led out and fixed to the outer wall of the housing 1. During charging, the user can pull the output / input line 12 from the reel 11 to connect it to an external electronic device for charging, or connect it to the charging interface of the first control circuit board 8 to charge the first battery cell 7. After charging is complete, the output / input line 12 is retracted into the housing 1 via the reel 11. The length of the output / input line 12 can be freely extended according to user convenience. The output / input line 12 can also be connected to an external power source to charge the second battery cell 9.

[0034] The usage process is as follows: When the user needs to use the waist-mounted fan, the fan is hung on the waist via hook 2. The fan switch is turned on, and after the first control circuit board 8 receives the switch signal, it controls the motor 5 to run. The motor 5 drives the fan blades 6 to rotate, and air enters the housing 1 from the air inlet 4 on the lower end. After being accelerated by the fan blades 6, it is blown out from the air outlet 3, achieving efficient cooling.

[0035] When the fan battery is low or an external electronic device needs charging, the user removes the charging terminal of the output / input cable 12. The output / input cable 12 is then connected to the charging port on the first control circuit board 8 or the charging port of the external electronic device. Current flows through the output / input cable 12 into the first control circuit board 8, which manages the charging process and stores electrical energy in the first battery cell 7. After charging is complete, the reel 11 automatically retracts the output / input cable 12, and the user secures the charging terminal to the side wall of the housing 1 for future use. The user can then connect the output / input cable 12 to an external power source to charge the second battery cell 9.

[0036] The housing 1 is provided with a magnet 13 at the fixed end of the output / input line 12, and the magnet 13 is used to attract the charging end of the output / input line 12.

[0037] Magnet 13 is installed inside the housing 1 at the corresponding charging end position. After use, magnet 13 is used to hold the output / input cable 12 and fix it to the side wall of the housing 1, making cable storage convenient and neat.

[0038] Preferably, the present invention includes an air guide 14, which is disposed at the air outlet 3. The outer wall of the air guide 14 radially contracts from the air inlet direction to the air outlet direction to pressurize the airflow.

[0039] The outer wall of the air guide 14 contracts radially from the air inlet direction to the air outlet direction, forming a gradually narrowing channel. As the cross-sectional area through which the airflow passes gradually decreases, the airflow is pressurized and the wind speed is higher under the premise that the air volume remains unchanged.

[0040] Specifically, the outer wall of the housing 1 is provided with a groove 15 for accommodating the charging terminal of the output / input line 12.

[0041] This utility model includes a warning light 16, which is disposed on the housing 1 and electrically connected to the first control circuit board 8.

[0042] The warning light 16 is activated by a button on the housing. The warning light 16 can be used in scenarios such as outdoor work, outdoor fishing, and outdoor cycling to warn the outside world.

[0043] This utility model includes a lighting lamp 17, which is disposed on the housing 1 and electrically connected to the first control circuit board 8.

[0044] The light 17 can be turned on by a button on the housing 1, or by using the same button as the warning light 16, and can be turned on via an editable method, such as turning on the light with a single press and turning on the warning light with two consecutive presses. The light 17 can provide illumination in scenarios such as outdoor work at night, outdoor fishing, and outdoor cycling. Furthermore, via an editable method, the illumination mode of the light 17 can be changed by pressing the button, for example, emitting an intermittent distress signal mode.

[0045] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
