[0023] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0024] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0026] Referring to Figures 1 and 2, the first embodiment of the present invention discloses a handheld fan 10, including a housing 11, a fan module 12, a power module 13, and a retractable cord module 14. The fan module 12, power module 13, and retractable cord module 14 are respectively disposed on the housing 11, and the housing 11 provides support and limit for these components. The power module 13 is used to supply power to the fan module 12. For example, physical buttons or virtual buttons can be provided on the housing 11. When the physical buttons or virtual buttons are triggered, the fan module 12 and the power module 13 can be connected or disconnected, thereby starting or stopping the fan module 12.

[0027] The retractable cable module 14 includes a cable 141 that can extend or retract relative to the housing 11 to be housed within or extend outside the housing 11. The cable 141 is used to connect to an external electronic device and supply power to the external electronic device via the power module 13. In some embodiments, the cable 141 can be coiled and housed within the housing 11 to achieve a concealed cable 141 effect, keeping the handheld fan 10 in a relatively simple appearance and avoiding inconvenience caused by the cable 141 during normal use. When the user needs to supply power to an external electronic device such as a mobile phone, the cable 141 of the retractable cable module 14 can be pulled out from the housing 11 and connected to the external electronic device, supplying power to these external electronic devices via the power module 13 of the handheld fan 10, for example, to charge a mobile phone.

[0028] Referring to Figure 3, in some embodiments, the cable 141 may include a cable body 1411, a connector 1413, and a digital display 1415. The digital display 1415 is connected between the free end of the cable body 1411 and the connector 1413, which is used to connect to an external electronic device. The connector 1413 may be a Type-C interface, a Micro-USB interface, or a Lightning interface, etc., and this application is not limited thereto. The digital display 1415 may include a display panel, such as an LCD panel or an OLED panel, to display information such as current and voltage during the operation of the cable 141, improving ease of use. Of course, the digital display 1415 is not mandatory; for example, in the embodiments shown in Figures 1, 2, and 4, the cable 141 does not have a digital display 1415.

[0029] Understandably, the power module 13 of the handheld fan 10 generally includes a rechargeable battery such as a lithium battery. As battery technology advances, battery capacity is on the rise, and the battery life of the handheld fan 10 is thus steadily improved. By combining the large-capacity battery of the handheld fan 10 with the retractable cable 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, thus improving the convenience of use.

[0030] 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 housed in the housing 11, and the power module 13 is housed in the housing 11 and supplies power to the fan module 12. The retractable cable module 14 is housed in the housing 11 and includes a cable 141 that can extend or retract relative to the housing 11 to be stored inside or outside the housing 11. The cable 141 is used to connect to an external electronic device and supplies power to the external electronic device through the power module 13. When a user carries the handheld fan 10 and needs to charge it, 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 supplies power to the external electronic device and provides charging functionality, eliminating the need to carry a separate power bank and charging cable, thus improving convenience. 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 supply power to the external electronic device. When the user no longer needs to power external electronic devices through the handheld fan 10, the cable 141 of the retractable cable module 14 can be basically stored inside the housing 11, and the handheld fan 10 can still maintain a relatively simple appearance, making it easy for users to carry and improving the convenience of use.

[0031] Referring to Figure 1, the housing 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 outward from the grip portion 111, or in other words, the air outlet portion 113 and the grip portion 111 are arranged side by side along the length of the handheld fan 10. The air outlet portion 113 is generally cylindrical and has an air outlet 113a. During operation, the fan module 12 can drive airflow out from the air outlet 113a to dissipate heat for the user. The position of the air inlet of the housing 11 can be varied. For example, the air inlet can be located on the side of the air outlet portion 113 opposite to the air inlet 113a, or it can be located in the grip portion 111. This application does not limit this. The power module 13 is disposed inside the grip portion 111. Of course, the power module 13 can also be disposed inside the air outlet portion 113. The fan module 12 can be located inside the air outlet 113 or inside the grip 111, and the telescopic cable module 14 can also be located inside the grip 111 or inside the air outlet 113. The first embodiment of this application is described using the example of the power module 13 being located in the grip 111, the fan module 12 in the air outlet 113, and the telescopic cable module 14 in the grip 111, and should not be considered a limitation of the solution.

[0032] In particular, in some embodiments, the fan module 12 may employ an air compressor, such as a booster turbine, to achieve a bladeless design for the handheld fan 10, thus achieving a bladeless fan effect and making the handheld fan 10 more aesthetically pleasing.

[0033] In the embodiment shown in Figure 1, the grip 111 and the air outlet 113 are integrally formed, resulting in a simpler appearance for the handheld fan 10 and easier processing. For example, the housing 11 can be mass-produced by injection molding. In other embodiments, the air outlet 113 can also be assembled and fixed to the grip 113, for example, by snap-fit, adhesive, or threaded connection, to improve the ease of assembly.

[0034] Referring to Figures 2 and 4, the handheld fan 10 includes a circuit board 15, which is disposed in either the grip portion 111 or the air outlet portion 113. That is, the circuit board 15 can be disposed within either the grip portion 111 or the air outlet portion 113. The first embodiment of this application uses the example of the circuit board 15 being disposed in the grip portion 111 for illustration, and should not be considered a limitation of the solution. The circuit board 15 can integrate the control circuitry, power management unit, etc., of the handheld fan 10. The power module 13, the fan module 12, and the cable 141 are electrically connected to the circuit board 15. The start / stop button, speed adjustment knob, and other components of the fan module 12 can be correspondingly configured with the control circuitry on the circuit board 15 to achieve the corresponding functions, which will not be elaborated further in this application.

[0035] Referring to Figures 2 and 4, the telescopic cable module 14 includes a housing 143 disposed within the grip portion 111. The housing 143 is fixed in position relative to the circuit board 15, and the cable 141 is telescopically disposed within the housing 143. The housing 143 can be fixedly connected to the circuit board 15 or to the grip portion 111 of the housing 11, thereby achieving relative fixation between the housing 143 and the circuit board 15. The telescopic cable module 14, including the housing 143, can be manufactured as an independent module and assembled into the handheld fan 10, thereby improving assembly efficiency and ensuring the reliability of the telescopic cable module 14 in operation.

[0036] Specifically, the telescopic cable module 14 may include a circuit board 144, a torsion spring 145, and a turntable 146 disposed within a housing 143. The circuit board 144 is fixedly positioned relative to the housing 143, for example, the circuit board 144 is fixedly connected to the housing 143 or the gripping part 111, and the circuit board 144 is electrically connected to the circuit board 15, for example, through wire bonding. The torsion spring 145 may be helical and has 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 turntable 146, and the second free end 1453 is fixedly positioned relative to the circuit board 144, for example, fixedly connected to the housing 143 or the circuit board 144. The turntable 146 is rotatably connected to the housing 143, for example, one of the turntable 146 and the housing 143 is provided with a rotating shaft, and the other is provided with a shaft hole, thereby realizing the rotatable connection between the turntable 146 and the housing 143. Cable 141 is wound around the outer periphery 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 makes contact with the ring conductor to conduct electricity. Cable 141 is electrically connected to the contact pin or ring conductor on turntable 146, thereby realizing the electrical connection between cable 141 and circuit board 144. For example, circuit board 144 is provided with a contact pin, turntable 146 is provided with a ring conductor, and cable 141 is electrically connected to the ring conductor; or circuit board 144 is provided with a ring conductor, turntable 146 is provided with a contact pin, and cable 141 is electrically connected to the contact pin, thus realizing the electrical connection between cable 141 and circuit board 144. Of course, cable 141 can also be directly electrically connected to circuit board 144 by means of wire bonding or other methods.

[0037] Cable 141 can be held in place by turntable 146. When the user pulls cable 141, it causes turntable 146 to rotate relative to housing 143 in one direction, such as clockwise, gradually extending beyond housing 143. During this process, the contact pin remains in contact with the annular conductor, thereby ensuring the 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 via handheld fan 10, torsion spring 145 can release elastic potential energy, causing cable 141 extending beyond housing 143 to gradually retract into housing 143.

[0038] Referring to Figure 5, in some embodiments, the telescopic cable module 14 includes a locking block 147 rotatably connected to the housing 143. The turntable 146 has a locking position 1461 and an unlocking position 1463. During the process of the cable 141 being pulled out of the housing 143, when the cable 141 drives the turntable 146 to rotate until the locking position 1461 corresponds to the locking block 147, the locking block 147 restricts the rotation of the turntable 146. When the cable 141 continues to be pulled out of the housing 143 and drives the turntable 146 to rotate, the locking block 147 rotates relative to the housing 143 and moves to the unlocking position 1463, so that the cable 141 can be gradually wound into the housing 143. Figure 5 shows that the turntable 146 is provided with corresponding limiting grooves 146a and guide grooves 146b. The groove wall of the limiting groove 146a can serve 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.

[0039] The sidewall of the guide groove 146b can guide and limit the movement of the end of the locking block 147, so that during the pulling out of the cable 141, the end of the locking block 147 continues to move along the guide groove 146b. When the user stops pulling the cable 141 out, the torsion spring 145 drives the turntable 146 to rotate in the opposite direction (e.g., clockwise), and the end of the locking block 147 is guided by the sidewall of the guide groove 146b into the limiting groove 146a, thereby stopping the cable 141. When the user continues to pull the cable 141 out, the turntable 146 continues to rotate in the original direction (e.g., counterclockwise), and the end of the locking block 147 exits the limiting groove 146a and enters the guide groove 146b, allowing the cable 141 to continue to be pulled out. It is understood that the above functions can be achieved by designing the depth and width of the guide groove 146b and the limiting groove 146a, which will not be elaborated further in this application.

[0040] When the user pulls the cable 141 out of the housing 143 and drives the turntable 146 to rotate, the end of the locking 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 of the locking block 147 abuts against the groove wall of the limiting groove 146a, and the turntable 146 stops rotating, thus achieving the locking effect of the cable 141. When the user continues to pull the cable 141 out of the housing 143 and drives the turntable 146 to rotate, the locking block 147 rotates relative to the housing 143 and retracts to the guide groove 146b. It can switch to the guide groove 146b and continue to move along the guide groove 146b, that is, reach the unlocking position 1463. The turntable 146 can continue to rotate, causing the cable 141 to continuously extend out of the housing 143, or the cable 141 can gradually be wound back into the housing 143. The combination of the above-mentioned locking block 147 and turntable 146 can achieve the locking and stopping of cable 141 and automatic winding, improving the convenience of use. Moreover, the turntable 146 can be set with more than two locking positions 1461 and unlocking positions 1463, and the locking positions 1461 and unlocking positions 1463 can be matched one-to-one.

[0041] Of course, in other embodiments, other structures can be used to replace the locking effect of the locking block 147 on the cable 141. For example, the handheld fan 10 may include a limiting member (not shown) that is movably engaged with the grip portion 111 or the circuit board 15. The limiting member 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 limiting member abuts against the cable 141 and restricts the movement of the cable 141 relative to the grip portion 111.

[0042] For example, the limiting member slides in conjunction with the gripping part 111, and the sliding of the limiting member and the gripping part 111 has appropriate damping to prevent the limiting member from easily retracting. When the user needs to stop the cable 141 while pulling it out, the limiting member is pushed relative to the gripping part 111 to the position where it presses against the cable 141, i.e., the second position, which can stop the cable 141 in the gripping part 111; when the user needs to retract the cable 141 into the gripping part 111, the limiting member is pushed in the opposite direction to the first position. After the limiting member no longer presses against the cable 141, the cable 141 can be retracted into the cover 143 under the action of the torsion spring 145 and the turntable 146.

[0043] For example, the limiting member rotates in conjunction with the gripping part 111. The limiting member may have an eccentric wheel structure and appropriate rotational damping to prevent the limiting member from easily retracting. When the user needs to stop the cable 141 while pulling it out, the limiting member is rotated to the second position, so that the eccentric wheel of the limiting member presses against the cable 141, thus stopping the cable 141 in the gripping part 111. When the user needs to retract the cable 141 into the gripping part 111, the limiting member is rotated in the opposite direction to the first position. After the eccentric wheel of the limiting member no longer presses against the cable 141, the cable 141 can be retracted into the cover 143 under the action of the torsion spring 145 and the turntable 146.

[0044] Both of the above-described limiting components can stop the cable 141, and when combined with the torsion spring 145, they can achieve an automatic winding effect, improving ease of use. In other embodiments, the limiting components can also adopt other structural forms to achieve the same stopping effect on the cable 141.

[0045] It is understandable that the housing 143 of the telescopic cable module 14 is not necessary and can be omitted to simplify the structure of the handheld fan 10 and improve its compactness. For example, the telescopic cable module 14 includes a torsion spring 145 and a turntable 146 rotatably connected to one of the grip 111 and the circuit board 15. 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 position of the circuit board 15. The cable 141 is wound around the outer periphery of the torsion spring 145 and electrically connected directly to the circuit board 15, or the cable 141 is electrically connected to the circuit board 15 through a contact pin and a ring conductor. The cable 141 can be held in place by the turntable 146. When the user pulls the cable 141, the turntable 146 rotates relative to the grip 111 in one direction, such as clockwise, gradually extending beyond 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 power external electronic devices via the handheld fan 10, the torsion spring 145 releases its elastic potential energy, causing the cable 141 extending beyond the grip 111 to gradually retract back into the grip 111.

[0046] In this embodiment, the telescopic cable module 14 may also include a locking block 147 rotatably connected to one of the grip 111 and the circuit board 15. The turntable 146 has a locking position 1461 and an unlocking position 1463. During the process of the cable 141 being pulled out of the grip 111, the cable 141 drives the turntable 146 to rotate until the locking position 1461 corresponds to the locking block 147, at which point the locking block 147 restricts the rotation of the turntable 146. When the cable 141 continues to be pulled out of the grip 111 and drives the turntable 146 to rotate, the locking block 147 moves relative to the turntable 146 to the unlocking position 1463, so that the cable 141 gradually rewinds into the grip 111. The locking principle and structure of the locking block 147 for the cable 141, as well as the unlocking principle and structure, can be referred to the foregoing content and will not be repeated here. The combination of the above-mentioned locking block 147 and turntable 146 can stop the cable 141, and combined with the torsion spring 145, it can achieve an automatic winding effect, improving the convenience of use.

[0047] Of course, in this embodiment, the handheld fan 10 may also include a limiting member that is movably coupled to one of the grip portion 111 and the circuit board 15. The limiting member 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 limiting member abuts against the cable 141 and restricts the movement of the cable 141 relative to the grip portion 111. The principle and structure of the limiting member in stopping the cable 141, as well as the principle and structure of unlocking the cable 141, can be referred to the foregoing and will not be repeated here. The structure of the limiting member can achieve the stopping of the cable 141, and combined with the torsion spring 145, it can achieve an automatic winding effect, improving the convenience of use. In other embodiments, the limiting member may also adopt other structural forms to achieve the stopping effect of the cable 141. Example

[0048] Referring to Figures 6, 7, and 8, a second embodiment of the present invention discloses a handheld fan 20, including a housing 21, a fan module 22, a power module 23, and a retractable cable module 24. The fan module 22, power module 23, and retractable cable module 24 are respectively disposed in the housing 21, and the housing 21 provides support and restraint 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 extend and retract relative to the housing 21 to be housed within the housing 21 or extend outside the housing 21. The cable 241 is used to connect to external electronic devices and supply power to the external electronic devices through the power module 23.

[0049] Referring to Figure 6, the housing 21 includes a grip portion 211 and an air outlet 213 connected to one end of the grip portion 211. The air outlet 213 protrudes from the grip portion 211, or in other words, the air outlet 213 and the grip portion 211 are arranged side by side along the length of the handheld fan 10. The air outlet 213 has an air outlet 213a. During operation, the fan module 22 can drive airflow out from the air outlet 213a to dissipate heat for the user. The air inlet position of the housing 21 can be varied; for example, the air inlet can be located in the air outlet 213 or in the grip portion 211. This application does not limit this. The power module 23 is disposed within the grip portion 211 or the air outlet 213. The fan module 22 can be disposed within the air outlet 213 or the grip portion 211, and the telescopic cable module 24 can also be disposed within the grip portion 211 or the air outlet 213. The second embodiment of this application is described using the example of the power module 23 being located in the grip 211, the fan module 22 and the telescopic cable module 24 being located in the air outlet 213, and should not be regarded as a limitation on the solution.

[0050] Unlike the first embodiment, in the second embodiment of this application, the grip portion 211 and the air outlet portion 213 of the handheld fan 20 are rotatably connected. 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 for user convenience. In particular, in some embodiments, by rotating the air outlet portion 213 and the grip portion 211, the air outlet portion 213 can be folded and folded into the grip portion 211 when not in use, thereby reducing the overall size of the handheld fan 20 and further improving portability.

[0051] Referring to Figures 7 and 8, in some embodiments, the handheld fan 20 includes a circuit board 25, which is disposed 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 describes the circuit board 25 as being disposed in the air outlet 213; in other embodiments, the circuit board 25 may be disposed within the grip 211. Further details will not be provided here.

[0052] In the second embodiment of this application, the cable 241 of the retractable cable module 24 can be wound and stored inside the air outlet 213 to achieve a hidden cable 241 effect, allowing the handheld fan 20 to maintain a relatively simple appearance and avoiding inconvenience caused by the cable 241 to the user during daily use. When the user needs to power external electronic devices such as mobile phones, the cable 241 of the retractable cable module 24 can be pulled out from inside the air outlet 213 and connected to the external electronic device. The power module 23 of the handheld fan 20 can then power these external electronic devices, such as charging a mobile phone.

[0053] Referring to Figure 9, in some embodiments, the cable 241 may also include a cable body 2411, a connector 2413, and a digital display 2415. The digital display 2415 is connected between the free end of the cable body 2411 and the connector 2413, which is used to connect to an external electronic device. The connector 2413 can be a Type-C interface, a Micro-USB interface, or a Lightning interface, etc., and this application is not limited to this. The digital display 2415 may include a display panel, such as an LCD panel or an OLED panel, to display information such as current and voltage during the operation of the cable 241, improving ease of use. Of course, the digital display 2415 is not necessary and can be omitted.

[0054] Understandably, the power module 23 of the handheld fan 20 generally includes a rechargeable battery such as a lithium battery. As battery technology advances, battery capacity is on the rise, and the battery life of the handheld fan 20 is thus steadily improving. By combining the large-capacity battery of the handheld fan 20 with the retractable cable 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, thus improving the convenience of use.

[0055] 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 located in the air outlet 213 of the housing 21. The power module 23 is located in the grip 211 of the housing 21 and supplies power to the fan module 22. The retractable cable module 24 is located in the air outlet 213 and includes a cable 241 that can extend or retract relative to the air outlet 213 to be stored inside or outside the air outlet 213. The cable 241 is used to connect to an external electronic device and supplies power to the external electronic device through the power module 23. When a user carries the handheld fan 20 and needs to charge it, the cable 241 of the retractable cable module 24 can be pulled out from 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 supplies power to the external electronic device, for example, to achieve a charging function, thus eliminating the need to carry a separate power bank and charging cable, improving the convenience of use. When the external electronic device does not have a rechargeable battery, the user can also power the external electronic device using the power module 23 of the handheld fan 20. When the user no longer needs to power the external electronic device through the handheld fan 20, the cable 241 of the retractable cable module 24 can be basically stored inside the air outlet 213, and the user can 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 easy for the user to carry and improving the convenience of use.

[0056] Specifically, referring again to Figures 7 and 8, in some embodiments, the air outlet 213 may include a fan shroud 2131 and a mounting portion 2133 connected to the fan shroud 2131. The fan shroud 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. The implementation of this embodiment can be referred to in the first embodiment, and will not be repeated here.

[0057] Similar to the first embodiment, the retractable cable module 24 may include a housing 243 disposed within the mounting portion 2133. The housing 243 is fixed in position relative to the circuit board 25, and the cable 241 is retractably disposed within the housing 243. The housing 243 may be fixedly connected to the circuit board 25 or fixedly connected to the mounting portion 2133, thereby achieving relative fixation between the housing 243 and the circuit board 25. The retractable cable module 24, including the housing 243, can be manufactured as an independent module and assembled into the handheld fan 20, thereby improving assembly efficiency and ensuring the reliability of the retractable cable module 24 in operation.

[0058] 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 is fixed in position relative to the housing 243, and the circuit board 244 is electrically connected to the circuit board 25, for example, through wire bonding. The first free end 2451 of the torsion spring 245 is connected to the turntable 246, and the 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 outer periphery of the torsion spring 245. One of the circuit board 244 and the turntable 246 is provided with a contact pin (not shown), and the other is provided with a ring conductor (not shown). The contact pin contacts the ring conductor to conduct electricity, and the cable 241 is electrically connected to the contact pin or the ring conductor on the turntable 246. Cable 241 is used to pull turntable 246 to rotate relative to housing 243 so that it gradually extends out of housing 243. Turntable 246 is used to drive cable 241, which extends out of housing 243, to gradually rewind into housing 243. The structure and principle of telescopic cable module 24 and its cooperation with mounting part 2133 of housing 21 can be referred to the first embodiment, and will not be repeated here. Of course, cable 241 can also be directly electrically connected to circuit board 244 by means of lead soldering or other methods.

[0059] Of course, referring to Figure 10, the telescopic cable module 24 may also include a locking block 247 rotatably connected to the housing 243. The turntable 246 has a locking position 2461 and an unlocking position 2463. During the process of the cable 241 being pulled out of the housing 243, when the cable 241 drives the turntable 246 to rotate to the locking position 2461 corresponding to the locking block 247, the locking 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 locking block 247 rotates relative to the housing 243 and moves to the unlocking position 2463, so that the cable 241 can be gradually wound into the housing 243. The structure and principle of the locking block 247 cooperating with the turntable 246 to lock and unlock the cable 241 can be referred to the first embodiment. For example, the turntable 246 is provided with corresponding limiting grooves 246a and guide grooves 246b. The groove wall of the limiting groove 246a can be used as the locking position 2461, and the connection between the groove wall of the guide groove 246b and the groove wall of the limiting groove 246a is the unlocking position 2463. This will not be elaborated here.

[0060] Of course, in other embodiments, other structures can be used to replace the locking effect of the locking block 247 on the cable 241. For example, the handheld fan 20 may include a limiting member (not shown) that is movably fitted to the mounting part 2133 or the circuit board 25. The limiting 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 part 2133. In the second position, the limiting member abuts against the cable 241 and restricts the movement of the cable 241 relative to the mounting part 2133.

[0061] For example, the limiting member slides in conjunction with the mounting part 2133, and the sliding of the limiting member and the mounting part 2133 has appropriate damping to prevent the limiting member from easily retracting. When the user needs to stop the cable 241 while pulling it out, the limiting member is pushed relative to the mounting part 2133 to the position where it abuts the cable 241, i.e., the second position, which stops the cable 241 in the mounting part 2133. When the user needs to retract the cable 241 into the mounting part 2133, the limiting member is pushed in the opposite direction to the first position. After the limiting member no longer abuts the cable 241, the cable 241 can be retracted into the mounting part 2133 under the action of the torsion spring 245 and the turntable 246.

[0062] For example, the limiting member rotatably engages with the mounting part 2133. The limiting member may have an eccentric wheel structure and appropriate rotational damping to prevent the limiting member from easily retracting. When the user needs to stop the cable 241 while pulling it out, the limiting member is rotated to the second position, so that the eccentric wheel of the limiting member presses against the cable 241, thus stopping the cable 241 in the mounting part 2133. When the user needs to retract the cable 241 into the mounting part 2133, the limiting member is rotated in the opposite direction to the first position. After the eccentric wheel of the limiting member no longer presses against the cable 241, the cable 241 can be retracted into the mounting part 2133 under the action of the torsion spring 245 and the turntable 246.

[0063] Both of the above-described limiting components can achieve the stopping and automatic winding effect of cable 241, improving ease of use. In other embodiments, the limiting components can also adopt other structural forms to achieve the stopping effect of cable 241.

[0064] Similar to the first embodiment, the retractable cable module 24 may also omit the housing 243 to improve the structural compactness of the handheld fan 20. For example, the retractable cable module 24 can achieve the retractable movement of the cable 241 relative to the mounting portion 2133 by including a torsion spring 245 and a turntable 246 rotatably connected to either the mounting portion 2133 or the circuit board 25. Specifically, the first free end 2451 of the torsion spring 245 can be connected to the turntable 246, the second free end 2453 of the torsion spring 245 is fixed relative to the position of 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, and the turntable 246 is used to drive the cable 241 extending out of the mounting portion 2133 to gradually rewind back into the mounting portion 2133. When the cover 243 is defaulted, the structure and working principle of the torsion spring 245, turntable 246, mounting part 2133, and circuit board 25 can be referred to the first embodiment, and will not be repeated here.

[0065] In this embodiment, the telescopic cable module 24 may also include a locking block 247 rotatably connected to one of the mounting portion 2133 and the circuit board 25. The turntable 246 has a stopping position 2461 and an unlocking position 2463. During the process of the cable 241 being pulled out of the mounting portion 2133, the cable 241 drives the turntable 246 to rotate until the stopping position 2461 corresponds to the locking block 247, at which point the locking block 247 restricts the rotation of the turntable 246. As the cable 241 continues to be pulled out of the mounting portion 2133 and drives the turntable 246 to rotate, the locking block 247 moves relative to the turntable 246 to the unlocking position 2463, so that the cable 241 gradually rewinds into the mounting portion 2133. The structure and principle of the locking block 247 and the turntable 246 cooperating to stop and unlock the cable 241 can be referred to in the first embodiment, and will not be repeated here.

[0066] Of course, in this embodiment, the handheld fan 20 may also include a limiting member that is movably coupled to the mounting portion 2133 or the circuit board 25. The limiting 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 limiting member abuts against the cable 241 and restricts the movement of the cable 241 relative to the mounting portion 2133. The limiting member and the mounting portion 2133 may adopt a sliding fit structure or a rotating fit structure, as described in the first embodiment, which will not be repeated here. Of course, the structure for stopping and unlocking the cable 241 in the mounting portion 2133 may also have other forms, such as stopping the pulled-out cable 241 and allowing the cable 241 to be easily retracted into the mounting portion 2133 when the user does not need the cable 241 to be stopped, which will not be repeated here.

[0067] Referring to Figure 11, in some embodiments, at least one of the air outlet 213 and the grip 211 is provided with an engaging structure (not shown). The engaging structure is used to engage 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 structure for suspension to the human body. Exemplarily, the air outlet 213 may be provided with a slot (not shown) and a locking plate (not shown) that slides with the air outlet 213. After the user pulls out the cable 241 stored in the housing 21, the free end of the cable 241 can be inserted into the slot, and then the locking plate can be pushed to cover the slot, engaging the cable 241 with the air outlet 213. The cable 241 thus forms a ring structure for suspension to the human body. The user can suspend the handheld fan 20 around their neck through the ring structure, or place their hand through the ring structure. After the air outlet 213 rotates a certain angle, such as 85 degrees, relative to the grip 211, the user can hold the fan 20 and suspend it around their neck via the ring structure. The air outlet 213 can still blow air towards the face, freeing the user's hands to do other things, thus improving the convenience of using the handheld fan 20 and expanding its usage scenarios. After the user retracts the latch, the free end of the cable 241 can be unlocked from the housing 21 and then normally wound back into the housing 21. The latching structure can also have other forms, such as an openable and closable buckle on the air outlet 213 or the grip 211. After opening the buckle, the free end of the cable 241 can be inserted. After the buckle is closed, the free end of the cable 241 can also be locked in the housing 21, thus forming a ring structure for hanging on the human body.

[0068] Of course, in the first embodiment of this application, a snap-fit ​​structure can also be provided on the housing 21 to fix the free end of the cable 241 to the housing 21, so as to form a ring structure for hanging to the human body, thereby facilitating the carrying of the handheld fan 20. This will not be elaborated here.

[0069] Furthermore, referring to FIG12, in some embodiments, at least one of the air outlet 213 and the grip 211 has a shaft hole 21a. The axis of rotation of the air outlet 213 relative to the grip 211 passes through the shaft hole 21a. The cable 241 is used to extend from one end of the shaft hole 21a and extend into and be secured from the opposite end of the shaft hole 21a to form a loop structure for suspension to the human body. Utilizing the rotational structure of the air outlet 213 relative to the grip 211, the cable 241 can be configured to extend from one end of the shaft hole 21a and extend into and be secured from the opposite end of the shaft hole 21a, thereby forming a reliable loop structure. The securing of the cable 241 in the shaft hole 21a is not limited to buttons, eccentric wheels, or sliders, etc., and will not be described further here. In this embodiment, the cable 241 passes through the shaft hole 21a. When the cable 241 is suspended around the neck of a person through the loop structure of the cable 241, the grip part 211 can be basically vertical and fits the human body more closely. The force is more stable, which can prevent the top corner of the grip part 211 from frequently hitting the human body due to the relative tilt of the grip part 211 to the direction of gravity, thereby improving the comfort of use.

[0070] Of course, referring to Figure 13, in embodiments where at least one of the air outlet 213 and the grip 211 has a shaft hole 21a, the housing 21 may not have a locking structure. The handheld fan 20 may include a lanyard 27 passing through the shaft hole 21a, and the lanyard 27 has a loop structure for hanging to the human body. The lanyard 27 can also improve the ease of use of the handheld fan 20 and expand the application scenarios of the handheld fan 20, and can avoid setting up a complex locking structure, thereby simplifying the structure of the handheld fan 20 and reducing the manufacturing cost of the handheld fan 20.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0072] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
