[0056] First embodiment

[0057] refer to Figure 1 and Figure 2 The first embodiment of the present invention discloses a handheld fan 10, comprising a housing 11, a fan module 12, a power module 13, and a retractable cable module 14. The fan module 12, the power module 13, and the retractable cable module 14 are respectively disposed in the housing 11, which provides support and position limiting for these components. The power module 13 is used to supply power to the fan module 12. For example, a physical button or a virtual button may be provided on the housing 11. When the button is triggered, the fan module 12 and the power module 13 are connected or disconnected, thereby starting or stopping the fan module 12.

[0058] The retractable wire module 14 includes a cable 141 that can be retracted relative to the housing 11 to be stored in the housing 11 or extended outside the housing 11. The cable 141 is used to connect to an external electronic device and power the external electronic device through the power module 13. In some embodiments, the cable 141 can be wound and stored in the housing 11 to achieve a hidden effect of the cable 141, so that the handheld fan 10 maintains a relatively simple appearance and avoids the cable 141 causing inconvenience to the user's daily use. When the user needs to power an external electronic device such as a mobile phone, the cable 141 of the retractable wire module 14 can be pulled out of the housing 11 and connected to the external electronic device. The power module 13 of the handheld fan 10 is used to power these external electronic devices, such as charging a mobile phone.

[0059] refer to Figure 3In some embodiments, the cable 141 may include a wire body 1411, a docking portion 1413 and a digital display portion 1415. The digital display portion 1415 is connected between the free end of the wire body 1411 and the docking portion 1413. The docking portion 1413 is used to dock to an external electronic device. The docking portion 1413 may be a Type-C interface, or a Micro-USB interface, or a Lightning interface, etc., which is not limited in this application. The digital display portion 1415 may include a display panel such as a liquid crystal panel or an OLED panel to display information such as current and voltage during the operation of the cable 141 to improve the convenience of use. Of course, the digital display portion 1415 is not necessary. For example, in Figure 1 、 Figure 2 and Figure 4 In the illustrated embodiment, the cable 141 does not include a digital display 1415 .

[0060] It can be understood that the power module 13 of the handheld fan 10 generally includes a battery that can be repeatedly charged and discharged, such as a lithium battery, and with the advancement of battery technology, the capacity of the battery has a continuous upward trend, and the battery life performance of the handheld fan 10 has also been steadily improved. By utilizing the large-capacity battery of the handheld fan 10 in combination with the telescopic wire module 14, the power module 13 of the handheld fan 10 can be used to power external electronic devices, such as charging a mobile phone, thereby improving the convenience of use.

[0061] The handheld fan 10 includes a housing 11, a fan module 12, a power module 13, and a retractable cable module 14. The fan module 12 is disposed in the housing 11. The power module 13 is disposed in the housing 11 and is used to power the fan module 12. The retractable cable module 14 is disposed in the housing 11 and includes a cable 141 that can be retracted relative to the housing 11 to be stored in the housing 11 or extended outside the housing 11. The cable 141 is used to connect to an external electronic device and power the external electronic device through the power module 13. When a user carries the handheld fan 10 and needs to charge the fan, the cable 141 of the retractable cable module 14 can be pulled out from the housing 11 of the handheld fan 10 and connected to an external electronic device such as a mobile phone. The power module 13 of the handheld fan 10 is used to power the external electronic device and realize the charging function, thereby eliminating the need to carry a mobile power supply and charging cable, thereby improving the convenience of use. When the external electronic device does not have a rechargeable battery, the user can also use the power module 13 of the handheld fan 10 to power the external electronic device. When the user no longer needs to use the handheld fan 10 to power external electronic devices, the cable 141 of the retractable wire module 14 can be basically stored in the shell 11, and the handheld fan 10 can still maintain a relatively simple appearance, which is convenient for users to carry and improves the convenience of use.

[0062] refer to Figure 1The shell 11 includes a grip portion 111 and an air outlet portion 113 connected to one end of the grip portion 111. The air outlet portion 113 protrudes from the grip portion 111, or the air outlet portion 113 and the grip portion 111 are arranged side by side in the length direction of the handheld fan 10. The air outlet portion 113 is roughly cylindrical and has an air outlet 113a. During operation, the fan module 12 can drive the air flow out from the air outlet 113a to dissipate heat for the user. The position of the air inlet of the shell 11 can have various deformations. For example, the air inlet can be located on the side of the air outlet portion 113 away from the air inlet 113a, or it can be located on the grip portion 111. This application does not impose any restrictions on this. The power supply module 13 is arranged in the grip portion 111. The fan module 12 can be disposed in the air outlet portion 113 or in the grip portion 111, and the retractable wire module 14 can also be disposed in the grip portion 111 or in the air outlet portion 113. The first embodiment of the present application is described by taking the fan module 12 disposed in the air outlet portion 113 and the retractable wire module 14 disposed in the grip portion 111 as an example, which should not be construed as limiting the solution.

[0063] In particular, in some embodiments, the fan module 12 can use an air compressor such as a booster turbine to achieve a design without an impeller on the appearance of the handheld fan 10, that is, to achieve a bladeless fan effect, making the appearance of the handheld fan 10 more concise.

[0064] exist Figure 1 In the illustrated embodiment, the grip portion 111 and the air outlet portion 113 are integrally formed, making the handheld fan 10 simpler in appearance and easier to process. For example, injection molding can be used to mass-produce the housing 11. In other embodiments, the air outlet portion 113 can also be assembled and fixed to the grip portion 113, for example, by means of a snap connection, adhesive connection, or threaded connection, to enhance assembly convenience.

[0065] refer to Figure 2 、 Figure 4 The handheld fan 10 includes a circuit board 15, and the circuit board 15 is provided in one of the grip portion 111 and the air outlet portion 113, that is, the circuit board 15 can be provided in the grip portion 111 or in the air outlet portion 113. The first embodiment of the present application is described by taking the circuit board 15 provided in the grip portion 111 as an example, which should not be regarded as a limitation to the scheme. The circuit board 15 can integrate the control circuit, power management unit, etc. of the handheld fan 10, and the power module 13, the fan module 12 and the cable 141 are electrically connected to the circuit board 15 respectively. The start and stop button, speed adjustment knob and other devices of the fan module 12 can be set corresponding to the control circuit on the circuit board 15 to realize the corresponding functions, which will not be described in detail in this application.

[0066] refer to Figure 2 、 Figure 4The retractable cable module 14 includes a housing 143 disposed within the grip 111. The housing 143 and the circuit board 15 are fixed relative to each other, and the cable 141 is retractably disposed within the housing 143. The housing 143 can be fixedly connected to the circuit board 15 or to the grip 111 of the housing 11, thereby maintaining a fixed position relative to the circuit board 15. The retractable cable module 14, including the housing 143, can be manufactured as a standalone module and assembled into the handheld fan 10, thereby improving assembly efficiency and ensuring the reliability of the retractable cable module 14.

[0067] Specifically, the telescopic cable module 14 may include a circuit board 144, a torsion spring 145, and a rotating disk 146 disposed within a housing 143. The circuit board 144 is fixed relative to the housing 143, for example, fixedly connected to the housing 143 or the grip 111. The circuit board 144 is electrically connected to the circuit board 15, for example, by wire bonding. The torsion spring 145 may be helical and have a first free end 1451 and a second free end 1453. The first free end 1451 of the torsion spring 145 is connected to the rotating disk 146, while the second free end 1453 is fixed relative to the circuit board 144, for example, fixedly connected to the housing 143 or the circuit board 144. The rotating disk 146 is rotatably connected to the housing 143, for example, by having a rotating shaft on one of the two, and a shaft hole on the other, thereby achieving the rotatable connection between the rotating disk 146 and the housing 143. Cable 141 is wound around the outer circumference of torsion spring 145. One of circuit board 144 and turntable 146 is provided with a contact pin (not shown), and the other is provided with a ring conductor (not shown). The contact pin contacts and the ring conductor, and the cable 141 is electrically connected to the contact pin or the ring conductor on turntable 146, thereby achieving an electrical connection between cable 141 and circuit board 144. For example, circuit board 144 may be provided with a contact pin, turntable 146 may be provided with a ring conductor, and cable 141 may be electrically connected to the ring conductor; or circuit board 144 may be provided with a ring conductor, turntable 146 may be provided with a contact pin, and cable 141 may be electrically connected to the contact pin, thereby achieving an electrical connection between cable 141 and circuit board 144.

[0068] Cable 141 is retained by turntable 146. When the user pulls cable 141, turntable 146 rotates in a direction, such as clockwise, relative to housing 143, gradually extending out of housing 143. During this process, the contact pins maintain contact with the annular conductor, thereby ensuring electrical connection between cable 141 and circuit board 15. During this process, torsion spring 145 accumulates elastic potential energy, causing turntable 146 to tend to rotate counterclockwise. When the user no longer needs to power external electronic devices with handheld fan 10, torsion spring 145 releases this elastic potential energy, causing cable 141, which has been extended from housing 143, to gradually retract into housing 143.

[0069] refer to Figure 5In some embodiments, the telescopic cable module 14 includes a block 147 rotatably connected to the cover 143, and the turntable 146 has a stop position 1461 and an unlocking position 1463. When the cable 141 is pulled out of the cover 143, the cable 141 drives the turntable 146 to rotate to the stop position 1461 corresponding to the block 147, and the block 147 restricts the rotation of the turntable 146; when the cable 141 continues to be pulled out of the cover 143 and drives the turntable 146 to rotate, the block 147 rotates relative to the cover 143 and moves to the unlocking position 1463, so that the cable 141 can be gradually retracted into the cover 143. Figure 5 The dotted line shows the movement trajectory of the end locking point of the locking block 147 in the locking position 1461 and the unlocking position 1463. By setting corresponding limiting grooves 146a and guide grooves 146b on the turntable 146, the groove wall of the limiting groove 146a can be used as the locking position 1461, and the connection between the groove wall of the guide groove 146b and the groove wall of the limiting groove 146a is the unlocking position 1463.

[0070] When the user pulls the cable 141 out of the cover 143 and drives the turntable 146 to rotate, the end clamping point of the clamping block 147 moves along the guide groove 146b to the locking position 1461. At this time, if the user stops pulling the cable 141, under the action of the torsion spring 145, the end clamping point of the clamping block 147 abuts against the groove wall of the limit groove 146a, and the turntable 146 stops rotating, thereby achieving the locking effect of the cable 141; when the user continues to pull the cable 141 out of the cover 143 and drives the turntable 146 to rotate, the clamping block 147 rotates relative to the cover 143 and retracts to the guide groove 146b, and can switch to the guide groove 146b and continue to move along the guide groove 146b, that is, reaches the unlocking position 1463, and the turntable 146 can continue to rotate and make the cable 141 continue to extend out of the cover 143, or the cable 141 can be gradually reeled into the cover 143. The above-mentioned block 147 and the turntable 146 cooperate to realize the effect of locking and automatically reeling the cable 141, thereby improving the convenience of use. In addition, the turntable 146 can be provided with two or more locking positions 1461 and unlocking positions 1463, and the locking positions 1461 and the unlocking positions 1463 can correspond to each other one by one.

[0071] Of course, in other embodiments, other structures can be used to replace the blocking effect of the block 147 on the cable 141. For example, the handheld fan 10 may include a limiter (not shown) that is movably engaged with the grip portion 111. The limiter has a first position and a second position. In the first position, the cable 141 can be pulled out or retracted into the grip portion 111; in the second position, the limiter abuts the cable 141 and limits the movement of the cable 141 relative to the grip portion 111.

[0072] For example, the limiter is slidably engaged with the grip portion 111, and the sliding movement of the limiter and the grip portion 111 has appropriate damping to prevent the limiter from easily retreating. When the user needs to stop the cable 141 during the process of pulling out the cable 141, the limiter is pushed relative to the grip portion 111 to a position that presses against the cable 141, thereby stopping the cable 141 in the grip portion 111. When the user needs to retract the cable 141 into the grip portion 111, the limiter is pushed in the opposite direction. After the limiter no longer presses against the cable 141, the cable 141 can be rewound into the housing 143 under the action of the torsion spring 145 and the turntable 146.

[0073] For example, the stopper is rotatably engaged with the grip portion 111. The stopper may have an eccentric wheel structure and suitable rotational damping to prevent the stopper from easily retreating. When the user needs to stop the cable 141 during the process of pulling out the cable 141, the stopper is rotated so that the eccentric wheel of the stopper presses against the cable 141, thereby stopping the cable 141 in the grip portion 111. When the user needs to retract the cable 141 into the grip portion 111, the stopper is rotated in the opposite direction. After the eccentric wheel of the stopper no longer presses against the cable 141, the cable 141 can be rewound into the housing 143 under the action of the torsion spring 145 and the rotating disk 146.

[0074] The above two limiting member structures can achieve the cable 141 to stop, and combined with the torsion spring 145, can achieve an automatic winding effect, improving the convenience of use. In other embodiments, the limiting member can also adopt other structural forms to achieve the cable 141 to stop effect.

[0075] It is understood that the cover 143 of the retractable cable module 14 is not required and can be omitted to simplify the structure of the handheld fan 10 and improve its compactness. For example, the retractable cable module 14 includes a torsion spring 145 and a turntable 146. The first free end 1451 of the torsion spring 145 is connected to the turntable 146, and the second free end 1453 of the torsion spring 145 is fixed relative to the circuit board 15. The cable 141 is wound around the periphery of the torsion spring 145 and electrically connected to the circuit board 15 directly, or the cable 141 and the circuit board 15 are electrically connected via contact pins and a ring conductor. The cable 141 can be clamped to the turntable 146. When the user pulls the cable 141, the turntable 146 rotates in a direction, such as clockwise, relative to the grip 111 to gradually extend outside the grip 111. During this process, the torsion spring 145 accumulates elastic potential energy, causing the turntable 146 to tend to rotate counterclockwise. When the user no longer needs to use the handheld fan 10 to power external electronic devices, the torsion spring 145 releases its elastic potential energy, driving the cable 141 extending outside the grip portion 111 to gradually reel into the grip portion 111 .

[0076] In this embodiment, the telescopic cable module 14 may also include a clamping block 147, and the turntable 146 has a stop position 1461 and an unlocking position 1463. When the cable 141 is pulled out of the gripping portion 111, the cable 141 drives the turntable 146 to rotate to the stop position 1461 corresponding to the clamping block 147, and the clamping block 147 restricts the rotation of the turntable 146; when the cable 141 continues to be pulled out of the gripping portion 111 and drives the turntable 146 to rotate, the clamping block 147 moves relative to the turntable 146 to the unlocking position 1463, so that the cable 141 is gradually reeled into the gripping portion 111. The principle and structure of the clamping of the cable 141 by the clamping block 147 and the principle and structure of the unlocking can be referred to the above content and will not be repeated here. The cooperation of the above clamping block 147 and the turntable 146 can realize the clamping of the cable 141, and combined with the torsion spring 145, an automatic reeling effect can be achieved, thereby improving the convenience of use.

[0077] Of course, in this embodiment, the handheld fan 10 may also include a limiter that is movably engaged with the gripping portion 111, and the limiter has a first position and a second position. In the first position, the cable 141 can be pulled out or retracted into the gripping portion 111; in the second position, the limiter abuts the cable 141 and limits the movement of the cable 141 relative to the gripping portion 111. The principle and structure of the cable 141 being stopped by the limiter, as well as the principle and structure of unlocking the cable 141 can also refer to the above content and will not be repeated here. The structure of the limiter can achieve the stopping of the cable 141, and combined with the torsion spring 145, an automatic winding effect can be achieved, thereby improving the convenience of use. In other embodiments, the limiter can also adopt other structural forms to achieve the stopping effect of the cable 141.

[0078] Second embodiment

[0079] refer to Figure 6 、 Figure 7 and Figure 8 The second embodiment of the present invention discloses a handheld fan 20, comprising a housing 21, a fan module 22, a power module 23, and a retractable cable module 24. The fan module 22, the power module 23, and the retractable cable module 24 are respectively disposed in the housing 21, and the housing 21 provides support and position limiting for these components. The power module 23 is used to supply power to the fan module 22. The retractable cable module 24 includes a cable 241 that can be retracted relative to the housing 21 to be accommodated within the housing 21 or extended outside the housing 21. The cable 241 is used to connect to an external electronic device and supply power to the external electronic device through the power module 23.

[0080] refer to Figure 6The shell 21 includes a grip portion 211 and an air outlet portion 213 connected to one end of the grip portion 211. The air outlet portion 213 protrudes from the grip portion 211, or the air outlet portion 113 and the grip portion 111 are arranged side by side in the length direction of the handheld fan 10. The air outlet portion 213 has an air outlet 213a. During operation, the fan module 22 can drive the air flow out from the air outlet 213a to dissipate heat for the user. The position of the air inlet of the shell 21 can have various deformations. For example, the air inlet can be located in the air outlet portion 213 or in the grip portion 211. This application does not impose any restrictions on this. The power supply module 23 is arranged in the grip portion 211. The fan module 22 can be arranged in the air outlet portion 213 or in the grip portion 211, and the telescopic line module 24 can also be arranged in the grip portion 211 or in the air outlet portion 213. The second embodiment of the present application is described by taking the example that the fan module 22 and the telescopic line module 24 are respectively arranged in the air outlet portion 213, which should not be regarded as a limitation to the solution.

[0081] Unlike the first embodiment, in the second embodiment of the present application, the grip portion 211 of the handheld fan 20 is rotatably connected to the air outlet portion 213. That is, the air outlet portion 213 can rotate relative to the grip portion 211, thereby changing the angle between the two and adjusting the air outlet angle, making it more convenient for the user. In particular, in some embodiments, the rotatable connection between the air outlet portion 213 and the grip portion 211 allows the air outlet portion 213 to be folded against the grip portion 211 when not in use, thereby reducing the overall size of the handheld fan 20 and further improving portability.

[0082] refer to Figure 7 and Figure 8 In some embodiments, the handheld fan 20 includes a circuit board 25, which is located in either the air outlet 213 or the grip 211. The power module 23, the fan module 22, and the cable 241 are electrically connected to the circuit board 25. This application uses the example of the circuit board 25 being located in the air outlet 213. In other embodiments, the circuit board 25 can be located in the grip 211. This description will not be repeated here.

[0083] In the second embodiment of the present application, the cable 241 of the retractable cable module 24 can be wound and stored within the air outlet 213, thereby achieving a concealed effect of the cable 241, maintaining a relatively simple appearance of the handheld fan 20 and preventing the cable 241 from causing inconvenience to the user during daily use. When the user needs to power an external electronic device such as a mobile phone, the cable 241 of the retractable cable module 24 can be pulled out from the air outlet 213 and connected to the external electronic device, and then powered by the power module 23 of the handheld fan 20, such as charging a mobile phone.

[0084] refer to Figure 9In some embodiments, the cable 241 may also include a wire body 2411, a docking portion 2413 and a digital display portion 2415. The digital display portion 2415 is connected between the free end of the wire body 2411 and the docking portion 2413. The docking portion 2413 is used to dock to an external electronic device. The docking portion 2413 can be a Type-C interface, a Micro-USB interface, a Lightning interface, etc., which is not limited in this application. The digital display portion 2415 may include a display panel such as a liquid crystal panel or an OLED panel to display information such as current and voltage during the operation of the cable 241 to improve the convenience of use. Of course, the digital display portion 2415 is not necessary and can be omitted.

[0085] It can be understood that the power module 23 of the handheld fan 20 generally includes a battery that can be repeatedly charged and discharged, such as a lithium battery, and with the advancement of battery technology, the capacity of the battery has a tendency to continue to increase, and the battery life performance of the handheld fan 20 has therefore steadily improved. By utilizing the large-capacity battery of the handheld fan 20 in combination with the telescopic wire module 24, the power module 23 of the handheld fan 20 can be used to power external electronic devices, such as charging a mobile phone, thereby improving the convenience of use.

[0086] The handheld fan 20 includes a housing 21, a fan module 22, a power module 23, and a retractable cable module 24. The fan module 22 is disposed in the air outlet 213 of the housing 21. The power module 23 is disposed in the grip 211 of the housing 21 and is used to supply power to the fan module 22. The retractable cable module 24 is disposed in the air outlet 213 and includes a cable 241 that can be retracted relative to the air outlet 213 to be stored in the air outlet 213 or extended out of the air outlet 213. The cable 241 is used to connect to an external electronic device and power the external electronic device through the power module 23. When a user carries the handheld fan 20 and needs to charge the fan, the cable 241 of the retractable cable module 24 can be pulled out of the handheld fan 20 and connected to an external electronic device such as a mobile phone. The power module 23 of the handheld fan 20 can then be used to power the external electronic device, for example, to achieve a charging function. This eliminates the need to carry a separate power bank and charging cable, thereby improving convenience of use. When the external electronic device does not have a rechargeable battery, the user can also use the power module 23 of the handheld fan 20 to power the external electronic device. When the user no longer needs to use the handheld fan 20 to power the external electronic device, the cable 241 of the retractable cable module 24 can be basically stored in the air outlet 213. The user can also fold the air outlet 213 into the grip 211, reducing the overall size of the handheld fan 20 and maintaining a relatively simple appearance, making it easier for the user to carry and improve the convenience of use.

[0087] Specifically, continue to refer to Figure 7 and Figure 8In some embodiments, the air outlet portion 213 may include a hood 2131 and a mounting portion 2133 connected to the hood 2131. The hood 2131 is generally cylindrical and has an air outlet 213a. The mounting portion 2133 is generally hollow and rectangular and is rotatably connected to the grip portion 211. The circuit board 25 and the telescopic cable module 24 are disposed within the mounting portion 2133. In other embodiments, the circuit board 25 and the telescopic cable module 24 may be disposed within the grip portion 211 to reduce the size of the mounting portion 2133. Such implementations may refer to the first embodiment and will not be further described here.

[0088] Similar to the first embodiment, the retractable cable module 24 can include a housing 243 disposed within the mounting portion 2133. The housing 243 and the circuit board 25 are fixed relative to each other, and the cable 241 is retractably mounted within the housing 243. The housing 243 can be fixedly connected to the circuit board 25 or to the mounting portion 2133, thereby maintaining a fixed position relative to the circuit board 25. The retractable cable module 24, including the housing 243, can be manufactured as a standalone module and assembled within the handheld fan 20, thereby improving assembly efficiency and ensuring the reliability of the retractable cable module 24.

[0089] Specifically, the telescopic cable module 24 may include a circuit board 244, a torsion spring 245, and a turntable 246 disposed within a housing 243. The circuit board 244 and the housing 243 are fixed relative to each other and are electrically connected to the circuit board 25, for example, by wire bonding. A first free end 2451 of the torsion spring 245 is connected to the turntable 246, while a second free end 2453 of the torsion spring 245 is connected to the housing 243. The turntable 246 is rotatably connected to the housing 243, and the cable 241 is wound around the circumference of the torsion spring 245. One of the circuit board 244 and the turntable 246 is provided with a contact pin (not shown), while the other is provided with a ring conductor (not shown). The contact pin and the ring conductor are in electrical contact, and the cable 241 is electrically connected to the contact pin or the ring conductor on the turntable 246. The cable 241 is used to pull the rotary disk 246 to rotate relative to the housing 243, gradually extending it out of the housing 243. The rotary disk 246 is used to drive the cable 241 that has been extended out of the housing 243 to be gradually retracted into the housing 243. The structure and principle of the retractable cable module 24 and its cooperation with the mounting portion 2133 of the housing 21 can be found in the first embodiment and will not be repeated here.

[0090] Of course, combined Figure 10The retractable cable module 24 may also include a block 247 rotatably connected to the housing 243. The turntable 246 has a locking position 2461 and an unlocking position 2463. When the cable 241 is pulled out of the housing 243, the cable 241 drives the turntable 246 to rotate until the locking position 2461 corresponds to the block 247, and the block 247 restricts the rotation of the turntable 246. When the cable 241 continues to be pulled out of the housing 243 and drives the turntable 246 to rotate, the block 247 rotates relative to the housing 243 and moves to the unlocking position 2463, allowing the cable 241 to be gradually retracted into the housing 243. The structure and principle of the block 247 and the turntable 246 cooperating to achieve the locking and unlocking of the cable 241 can be referred to the first embodiment and will not be repeated here.

[0091] Of course, in other embodiments, other structures can be used to replace the blocking effect of the block 247 on the cable 241. For example, the handheld fan 20 may include a limit member (not shown) that is movably engaged with the mounting portion 2133. The limit member has a first position and a second position. In the first position, the cable 241 can be pulled out or retracted into the mounting portion 2133; in the second position, the limit member abuts the cable 241 and limits the movement of the cable 241 relative to the mounting portion 2133.

[0092] For example, the retaining member slides with the mounting portion 2133, and the sliding movement of the retaining member and the mounting portion 2133 has appropriate damping to prevent the retaining member from easily retreating. When the user needs to stop the cable 241 during the process of pulling out the cable 241, the retaining member is pushed relative to the mounting portion 2133 to slide until it is in contact with the cable 241, thereby securing the cable 241 in the mounting portion 2133. When the user needs to retract the cable 241 into the mounting portion 2133, the retaining member is pushed in the opposite direction. After the retaining member no longer acts to tighten the cable 241, the cable 241 can be rewound into the mounting portion 2133 under the action of the torsion spring 245 and the rotating disk 246.

[0093] For example, the retaining member rotates in conjunction with the mounting portion 2133. The retaining member may have an eccentric wheel structure and suitable rotational damping to prevent the retaining member from easily retreating. When the user needs to stop the cable 241 during the process of pulling out the cable 241, the retaining member is rotated so that the eccentric wheel of the retaining member presses against the cable 241, thereby locking the cable 241 in the mounting portion 2133. When the user needs to retract the cable 241 into the mounting portion 2133, the retaining member is rotated in the opposite direction. After the eccentric wheel of the retaining member no longer presses against the cable 241, the cable 241 can be rewound into the mounting portion 2133 under the action of the torsion spring 245 and the rotating disk 246.

[0094] The above two limiting member structures can achieve the effect of stopping and automatically reeling the cable 241, thereby improving the convenience of use. In other embodiments, the limiting member can also adopt other structural forms to achieve the effect of stopping the cable 241.

[0095] Similar to the first embodiment, the retractable cable module 24 can also be omitted from the housing 243 to enhance the compactness of the handheld fan 20. For example, the retractable cable module 24 can include a torsion spring 245 and a turntable 246 to enable the cable 241 to extend and retract relative to the mounting portion 2133. Specifically, the first free end 2451 of the torsion spring 245 can be connected to the turntable 246, while the second free end 2453 of the torsion spring 245 is fixed relative to the circuit board 25. The cable 241 is wound around the outer periphery of the torsion spring 245. The cable 241 is used to pull the turntable 246 to rotate relative to the circuit board 25 to gradually extend out of the mounting portion 2133. The turntable 246 is used to drive the cable 241, which has extended outside the mounting portion 2133, to gradually retract into the mounting portion 2133. When the housing 243 is omitted, the structural coordination and operating principle of the torsion spring 245, turntable 246, mounting portion 2133, and circuit board 25 can be referred to in the first embodiment and will not be further described here.

[0096] In this embodiment, the retractable cable module 24 may also include a clamping block 247, and the rotary disk 246 has a locking position 2461 and an unlocking position 2463. When the cable 241 is pulled out of the mounting portion 2133, the cable 241 drives the rotary disk 246 to rotate until the locking position 2461 corresponds to the clamping block 247, and the clamping block 247 restricts the rotation of the rotary disk 246. When the cable 241 continues to be pulled out of the mounting portion 2133 and drives the rotary disk 246 to rotate, the clamping block 247 moves relative to the rotary disk 246 to the unlocking position 2463, so that the cable 241 is gradually reeled into the mounting portion 2133. The structure and principle of the clamping block 247 and the rotary disk 246 cooperating to achieve the locking and unlocking of the cable 241 can be referred to the first embodiment and will not be repeated here.

[0097] Of course, in this embodiment, the handheld fan 20 may also include a limiter that movably fits in the mounting portion 2133. The limiter has a first position and a second position. In the first position, the cable 241 can be pulled out or retracted into the mounting portion 2133; in the second position, the limiter abuts the cable 241 and limits the movement of the cable 241 relative to the mounting portion 2133. The limiter and the mounting portion 2133 may adopt a sliding fit structure or a rotation fit structure. For details, please refer to the description of the first embodiment, which will not be repeated here. Of course, the structure for achieving the locking and unlocking of the cable 241 in the mounting portion 2133 may also have other forms, so as to achieve the locking of the pulled-out cable 241, and when the user does not need the cable 241 to be locked, the cable 241 can be conveniently retracted into the mounting portion 2133. This will not be repeated here.

[0098] refer to Figure 11 In some embodiments, at least one of the air outlet portion 213 and the grip portion 211 is provided with a snap-fit ​​structure (not shown), which is used to snap-fit ​​with one end of the cable 241 extending out of the housing 21, i.e., the free end of the cable 241, to form a ring-shaped structure for hanging on the human body. For example, the air outlet portion 213 may be provided with a slot (not shown) and a card plate (not shown) that slides with the air outlet portion 213. After the user pulls out the cable 241 stored in the housing 21, the user can extend the free end of the cable 241 into the slot, and then push the card plate to cover the slot, snapping the cable 241 into the air outlet portion 213. The cable 241 thus forms a ring-shaped structure for hanging on the human body. The user can hang the handheld fan 20 around the neck through the ring structure, or put his hand through the ring structure. After the air outlet 213 is rotated relative to the grip 211 to a certain angle, such as 85 degrees, the user can hang the handheld fan 20 around the neck through the ring structure. The air outlet 213 can still blow air toward the face, and the user can free their hands to do other things, thereby improving the convenience of using the handheld fan 20 and expanding the use scenarios of the handheld fan 20. After the user retracts the card plate, the free end of the cable 241 can be unlocked from the housing 21 and then normally retracted into the housing 21. The locking structure can also have other forms. For example, the air outlet 213 or the grip 211 is provided with an openable and closable buckle. After opening the buckle, the free end of the cable 241 can be inserted. After the buckle is fastened, the free end of the cable 241 can also be locked to the housing 21, thereby forming a ring structure for hanging on the human body.

[0099] Of course, in the first embodiment of the present application, a snap-fit ​​structure can also be provided on the shell 21 to fix the free end of the cable 241 to the shell 21 to form a ring structure for hanging on the human body, thereby facilitating the carrying of the handheld fan 20, which will not be repeated here.

[0100] Further, refer to Figure 12In some embodiments, at least one of the air outlet portion 213 and the grip portion 211 has an axial hole 21a. The axis of rotation of the air outlet portion 213 relative to the grip portion 211 passes through the axial hole 21a. The cable 241 is configured to extend from one end of the axial hole 21a and extend into and latch from the other end opposite the axial hole 21a, thereby forming a ring-shaped structure for hanging on a human body. By utilizing the rotation structure of the air outlet portion 213 relative to the grip portion 211, the cable 241 can be configured to extend from one end of the axial hole 21a and extend into and latch from the other end opposite the axial hole 21a, thereby forming a reliable ring-shaped structure. The latching of the cable 241 in the axial hole 21a is not limited to a button, an eccentric wheel, or a slider, and will not be described in detail here. In this embodiment, the cable 241 is passed through the shaft hole 21a. When the cable 241 is hung on the neck of the human body through the annular structure of the cable 241, the grip portion 211 can be basically along the vertical direction and fit more closely to the human body. The force it receives is relatively stable, which can prevent the top corner of the grip portion 211 from frequently colliding with the human body due to the deviation of the grip portion 211 relative to the direction of gravity, thereby improving the comfort of use.

[0101] Of course, reference Figure 13 In embodiments where at least one of the air outlet portion 213 and the grip portion 211 includes an axial hole 21a, the housing 21 may not include a snap-fit ​​structure. The handheld fan 20 may include a hanging cord 27 threaded through the axial hole 21a. The hanging cord 27 has a loop-shaped structure for hanging from a person's body. The hanging cord 27 also enhances the convenience of the handheld fan 20 and expands its use scenarios. It also avoids the need for a complex snap-fit ​​structure, thereby simplifying the structure of the handheld fan 20 and reducing its manufacturing cost.

[0102] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0103] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
