[0050] First embodiment

[0051] refer to Figure 1 and Figure 2The first embodiment of the present application discloses a wearable fan 10, comprising a shell assembly 11, a fan 12, a power module 13 and a retractable wire module 14. The shell assembly 11 is used to be worn on the user's body and provide support and positioning for other devices. The fan 12 is provided in the shell assembly 11, and the shell assembly 11 has an air outlet 11a for the fan 12 to discharge air. In some embodiments, the wearable fan 10 is used to be worn on the user's neck. This type of wearable fan 10 can also be called a neck-hanging fan. After the wearable fan 10 is worn on the user's neck, the fan 12 can be started to drive the air flow out from the air outlet 11a to dissipate heat for the area around the user's neck. The position of the air inlet of the shell assembly 11 can have various variations. For example, the air inlet can be located on the side of the shell assembly 11 away from the air outlet 11a, or it can be located at the end of the shell assembly 11. This application does not impose any restrictions on this. In particular, in some embodiments, the fan 12 can use an air compressor such as a supercharged turbine to achieve a design without an impeller on the appearance of the wearable fan 10, that is, to achieve the effect of a bladeless fan 12, making the appearance of the wearable fan 10 more concise.

[0052] The power module 13 is disposed within the housing 11 and is used to power the fan 12. The power module 13 of the wearable fan 10 typically includes a rechargeable battery, such as a lithium battery. With advancements in battery technology, battery capacity is increasing, and the battery life of the wearable fan 10 is also steadily improving.

[0053] The retractable wire module 14 is provided in the shell assembly 11 and includes a cable 141 that can be retracted relative to the shell assembly 11. The cable 141 can be stored in the shell assembly 11 and can be pulled out of the shell assembly 11 and docked to an external electronic device to power the external electronic device through the power module 13. In some embodiments, the cable 141 can be wound and stored in the shell assembly 11 to achieve a hidden effect of the cable 141, so that the wearable 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 shell assembly 11 and docked to the external electronic device, and these external electronic devices are powered by the power module 13 of the wearable fan 10, such as charging a mobile phone.

[0054] 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 is not limited to a Type-C interface, or a Micro-USB interface, or a Lightning interface, or a magnetic charging interface, etc. The digital display portion 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, thereby improving the convenience of use. Of course, the digital display portion 1415 is not necessary. For example, in Figure 1 、 Figure 2 In the illustrated embodiment, the cable 141 does not include a digital display 1415 .

[0055] The wearable fan 10 includes a housing assembly 11, a fan 12, a power module 13, and a retractable cable module 14. The housing is intended to be worn on the user's body. The fan 12 is disposed in the housing assembly 11, and the housing assembly 11 has an air outlet 11a for the fan 12 to discharge air. The power module 13 is disposed in the housing assembly 11 and is used to power the fan 12. The retractable cable module 14 is disposed in the housing assembly 11 and includes a cable 141 that can be retracted relative to the housing assembly 11. The cable 141 can be stored in the housing assembly 11 and can be pulled out of the housing assembly 11 and connected to an external electronic device to power the external electronic device through the power module 13. By utilizing the large-capacity battery of the wearable fan 10 in combination with the retractable cable module 14, the power module 13 of the wearable fan 10 can be used to power the external electronic device, improving the convenience of use. For example, when the user carries the wearable fan 10 and needs to charge it, the cable 141 of the retractable wire module 14 can be pulled out from the shell assembly 11 of the wearable fan 10 and connected to an external electronic device such as a mobile phone. The power module 13 of the wearable fan 10 can be used to power the external electronic device and realize the charging function, so there is no need to carry a mobile power supply and charging cable separately, which improves 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 wearable fan 10 to power the external electronic device. When the user no longer needs to power the external electronic device through the wearable fan 10, the cable 141 of the retractable wire module 14 can be stored in the shell assembly 11, and the wearable fan 10 can still maintain a relatively simple appearance, which is convenient for the user to carry and improves the convenience of use.

[0056] refer to Figure 4The shell assembly 11 is roughly C-shaped and may include a first shell 111 for being worn around the user's neck, and a second shell 113 connected to the end of the first shell 111. At least one of the first shell 111 and the second shell 113 has an air outlet 11a, that is, the air outlet 11a can be located in the first shell 111 or the second shell 113, or both the first shell 111 and the second shell 113 are provided with an air outlet 11a. At least one of the first shell 111 and the second shell 113 is equipped with a fan 12, for example, the fan 12 can be provided in the first shell 111 or the second shell 113, or the first shell 111 and the second shell 113 are respectively provided with a fan 12, and the air inlet, the air outlet 11a and the air duct connecting the air inlet and the air outlet 11a can be adaptively deformed. At least one of the first shell 111 and the second shell 113 is provided with a power supply module 13. Specifically, the power supply module 13 can be provided in the first shell 111 or the second shell 113, or both the first shell 111 and the second shell 113 are provided with a power supply module 13, thereby improving the battery life of the wearable fan 10. A retractable cable module 14 is provided in at least one of the first shell 111 and the second shell 113. For example, the retractable cable module 14 can be provided in the first shell 111, the second shell 113 is provided with the retractable cable module 14, or both the first shell 111 and the second shell 113 are provided with the retractable cable module 14.

[0057] In some embodiments, the first shell 111 and the second shell 113 are fixedly connected, for example, by injection molding, to form a single piece, thereby improving the efficiency of the processing and molding of the shell assembly 11 and reducing the cost of the shell assembly 11. In other embodiments, the shell assembly 11 can be formed by joining two half shells. This type of wearable fan 10 has a relatively simple structure and low processing cost.

[0058] Combined with Figure 5 In other embodiments, the first shell 111 is movably connected to the second shell 113 and the second shell 113 has a first state and a second state relative to the first shell 111. The first shell 111 is provided with a first air outlet 11a1 extending along the circumference of the user's neck, and the second shell 113 is provided with a fan 12 and a second air outlet 11a2. That is, the air outlet 11a of the shell assembly 11 may include a first air outlet 11a1 and a second air outlet 11a2. In the first state, the first air outlet 11a1 and the second air outlet 11a2 are connected and connected, that is, air can be supplied to the side and back of the user's neck through the first air outlet 11a1, as shown in FIG. Figure 1 In the second state, the first air outlet 11a1 deviates from the second air outlet 11a2 to adjust the direction of the second air outlet 11a2, as shown Figure 5 Reference Figure 5In the second state, the first air outlet 11a1 may not supply air or supply a small amount of air, and the fan 12 provided in the second shell 113 may supply air to the user's chest area or chin and face through the second air outlet 11a2, thereby improving the heat dissipation effect, expanding the usage scenarios, and improving the user experience.

[0059] Exemplarily, in this embodiment, one of the second shell 113 and the first shell 111 can be provided with an arc-shaped groove or a special-shaped groove 113a, and the other of the second shell 113 and the first shell 111 has a support rod 111a. The arc-shaped groove or the special-shaped groove 113a can guide and limit the movement of the support rod 111a. When the support rod 111a moves along the arc-shaped groove or the special-shaped groove 113a, the angle of the second shell 113 relative to the first shell 111 can be gradually changed, thereby realizing the deviation of the second air outlet 11a2 relative to the first air outlet 11a1 and changing the direction of the second air outlet 11a2.

[0060] Furthermore, in this embodiment, the two ends of the first shell 111 can be respectively connected to the second shell 113, and the two second shells 113 are both provided with a fan 12 and a second air outlet 11a2. The second shells 113 at both ends of the first shell 111 can respectively move relative to the first shell 111 to adjust the direction of the second air outlet 11a2. Since the second shells 113 at both ends of the first shell 111 can move independently, more usage scenarios can be expanded. For example, when one of the second shells 113 is in the first state, the fan 12 in the second shell 113 can supply air to the side neck and back neck of the user through the first air outlet 11a1; when the other second shell 113 is in the second state, the second shell 113 can supply air to the chest area or chin or face of the user through the second air outlet 11a2, thereby expanding the air supply area and improving the user experience.

[0061] Continue to refer Figure 4The wearable fan 10 includes a circuit board 15 disposed within the shell assembly 11. The retractable cable module 14 includes a cover 142 disposed within the shell assembly 11. The fan 12 and the power module 13 are electrically connected to the circuit board 15, respectively. The positions of the cover 142 and the circuit board 15 are relatively fixed, and the cable 141 is retractably disposed in the cover 142. The circuit board 15 can integrate the control circuit, power management unit, etc. of the wearable fan 10. The power module 13, the fan 12, and the cable 141 are electrically connected to the circuit board 15, respectively. The start / stop button, speed adjustment knob, and other components of the fan 12 can be set corresponding to the control circuit on the circuit board 15 to achieve corresponding functions. This will not be described in detail. The cover 142 can be fixedly connected to the circuit board 15, or it can be fixedly connected to the shell assembly 11, such as the first shell 111, so as to achieve relative fixation of the positions of the cover 142 and the circuit board 15. The retractable wire module 14 including the cover 142 can be made into an independent module and assembled into the wearable fan 10 , thereby improving the assembly efficiency and ensuring the reliability of the retractable wire module 14 .

[0062] Specifically, combined Figure 6 The telescopic cable module 14 may include a circuit board 143, a torsion spring 144, and a rotating disk 145 disposed within a housing 142. The circuit board 143 is fixed relative to the housing 142, for example, fixedly connected to the housing 142 or the first shell 111 of the housing assembly 11. The circuit board 143 is electrically connected to the circuit board 15, for example, by wire bonding. The torsion spring 144 may be helical and have a first free end 1441 and a second free end 1443. The first free end 1441 of the torsion spring 144 is connected to the rotating disk 145, while the second free end 1443 is fixed relative to the circuit board 143, for example, fixedly connected to the housing 142 or the circuit board 143. The rotating disk 145 is rotatably connected to the housing 142, 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 145 and the housing 142. Cable 141 is wound around the periphery of torsion spring 144. One of circuit board 143 and turntable 145 is provided with a contact pin (not shown), while the other is provided with a ring conductor (not shown). The contact pin contacts and conducts electricity with the ring conductor, electrically connecting cable 141 to the contact pin or ring conductor on turntable 145, thereby achieving electrical connection between cable 141 and circuit board 143. For example, circuit board 143 may be provided with a contact pin and turntable 145 may be provided with a ring conductor, electrically connecting cable 141 to the ring conductor; or circuit board 143 may be provided with a ring conductor and turntable 145 may be provided with a contact pin, electrically connecting cable 141 to the contact pin, thereby achieving electrical connection between cable 141 and circuit board 143. Of course, cable 141 may also be directly electrically connected to circuit board 143 through methods such as wire soldering.

[0063] Cable 141 is retained by turntable 145. When the user pulls cable 141, turntable 145 rotates in a direction, such as clockwise, relative to housing 142, gradually extending out of housing 142. 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 144 accumulates elastic potential energy, causing turntable 145 to tend to rotate counterclockwise. When the user no longer needs to power an external electronic device through wearable fan 10, torsion spring 144 releases this elastic potential energy, causing cable 141, which has been extended from housing 142, to gradually retract into housing 142.

[0064] Combined with Figure 6 In some embodiments, the telescopic cable module 14 includes a block 146 rotatably connected to the cover 142, and the turntable 145 has a stop position 1451 and an unlocking position 1453. When the cable 141 is pulled out of the cover 142, the cable 141 drives the turntable 145 to rotate to the stop position 1451 corresponding to the block 146, and the block 146 restricts the rotation of the turntable 145; when the cable 141 continues to be pulled out of the cover 142 and drives the turntable 145 to rotate, the block 146 rotates relative to the cover 142 and moves to the unlocking position 1453, so that the cable 141 can be gradually retracted into the cover 142. Figure 6 The dotted line shows the movement trajectory of the end locking point of the locking block 146 in the locking position 1451 and the unlocking position 1453. By setting corresponding limiting grooves 145a and guide grooves 145b on the turntable 145, the groove wall of the limiting groove 145a can be used as the locking position 1451, and the connection between the groove wall of the guide groove 145b and the groove wall of the limiting groove 145a is the unlocking position 1453.

[0065] When the user pulls the cable 141 out of the cover 142 and drives the turntable 145 to rotate, the end clamping point of the clamping block 146 moves along the guide groove 145b to the locking position 1451. At this time, if the user stops pulling the cable 141, under the action of the torsion spring 144, the end clamping point of the clamping block 146 abuts against the groove wall of the limit groove 145a, and the turntable 145 stops rotating, thus achieving the locking effect of the cable 141; when the user continues to pull the cable 141 out of the cover 142 and drives the turntable 145 to rotate, the clamping block 146 rotates relative to the cover 142 and retracts to the guide groove 145b, and can switch to the guide groove 145b and continue to move along the guide groove 145b, that is, reaches the unlocking position 1453, and the turntable 145 can continue to rotate and make the cable 141 continue to extend out of the cover 142, or the cable 141 can be gradually reeled into the cover 142. The above-mentioned block 146 and the turntable 145 cooperate to realize the effect of locking and automatically reeling the cable 141, thereby improving the convenience of use. In addition, the turntable 145 can be provided with two or more locking positions 1451 and unlocking positions 1453, and the locking positions 1451 and the unlocking positions 1453 can correspond to each other one by one.

[0066] Of course, in other embodiments, other structures can be used to replace the blocking effect of the block 146 on the cable 141. For example, the wearable fan 10 may include a limiter (not shown) that is movably engaged with the shell assembly 11 (the first shell 111 or the second shell 113). 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 shell assembly 11; in the second position, the limiter abuts the cable 141 and limits the movement of the cable 141 relative to the shell assembly 11.

[0067] For example, the limiter is in sliding engagement with the shell assembly 11, and the sliding movement of the limiter and the shell assembly 11 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 shell assembly 11 to slide to the position where it presses against the cable 141, i.e., the second position, so that the cable 141 can be stopped in the shell assembly 11; when the user needs to retract the cable 141 into the shell assembly 11, the limiter is pushed in the opposite direction to the first position. After the limiter no longer presses against the cable 141, the cable 141 can be rewound into the housing 142 under the action of the torsion spring 144 and the turntable 145.

[0068] For example, the limiting member is rotatably engaged with the shell assembly 11. The limiting member may have an eccentric wheel structure and suitable rotational damping to prevent the limiting member from easily retreating. When the user needs to stop the cable 141 during the process of pulling out the cable 141, the limiting member is rotated so that the eccentric wheel of the limiting member presses against the cable 141, i.e., reaches the second position, thereby stopping the cable 141 in the shell assembly 11. When the user needs to retract the cable 141 into the shell assembly 11, 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 rewound into the cover 142 under the action of the torsion spring 144 and the rotating disk 145.

[0069] The above two limiting member structures can achieve the cable 141 to stop, and combined with the torsion spring 144, 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.

[0070] It is understood that the cover 142 of the retractable cable module 14 is not required and can be omitted to simplify the structure of the wearable fan 10 and improve its compactness. For example, the retractable cable module 14 includes a torsion spring 144 and a turntable 145. The first free end 1441 of the torsion spring 144 is connected to the turntable 145, and the second free end 1443 of the torsion spring 144 is fixed relative to the circuit board 15. The cable 141 is wound around the periphery of the torsion spring 144 and electrically connected to the circuit board 15 directly, such as by soldering or wire welding, or by contact pins and a ring conductor. The cable 141 is retained by the turntable 145. When the user pulls the cable 141, the turntable 145 rotates in a direction, such as clockwise, relative to the housing assembly 11, gradually extending out of the housing assembly 11. During this process, the torsion spring 144 accumulates elastic potential energy, causing the turntable 145 to tend to rotate counterclockwise. When the user no longer needs to power the external electronic device through the wearable fan 10 , the torsion spring 144 releases elastic potential energy, driving the cable 141 extending outside the shell assembly 11 to gradually reel into the shell assembly 11 .

[0071] In this embodiment, the telescopic cable module 14 may also include a clamping block 146, and the turntable 145 has a locking position 1451 and an unlocking position 1453. When the cable 141 is pulled out of the shell assembly 11, the cable 141 drives the turntable 145 to rotate to the locking position 1451 corresponding to the clamping block 146, and the clamping block 146 restricts the rotation of the turntable 145; when the cable 141 continues to be pulled out of the shell assembly 11 and drives the turntable 145 to rotate, the clamping block 146 moves relative to the turntable 145 to the unlocking position 1453, so that the cable 141 is gradually reeled into the shell assembly 11. The principle and structure of the clamping of the cable 141 by the clamping block 146 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 146 and the turntable 145 can realize the locking of the cable 141, and combined with the torsion spring 144, an automatic reeling effect can be achieved, thereby improving the convenience of use.

[0072] Of course, in this embodiment, the wearable fan 10 may also include a limiter that is movably engaged with the shell assembly 11, 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 shell assembly 11; in the second position, the limiter abuts the cable 141 and limits the movement of the cable 141 relative to the shell assembly 11. The principle and structure of the stop of the cable 141 by the limiter, as well as the principle and structure of the unlocking, can also refer to the above content and will not be repeated here. The structure of the limiter can achieve the stop of the cable 141, and combined with the torsion spring 144, 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 stop effect of the cable 141.

[0073] Second embodiment

[0074] refer to Figure 7 、 Figure 8 and Figure 9In the second embodiment of the present application, another wearable fan 20 is provided, which also includes a shell assembly 21, a fan 22, a power module 23 and a retractable wire module 24. The shell assembly 21 is used to be worn on the user's body and provide support and positioning for other devices. The fan 22 is provided in the shell assembly 21, and the shell assembly 21 has an air outlet 21a for the fan 22 to discharge air. In some embodiments, the wearable fan 20 can be used to be worn on the user's collar or other locations. After the wearable fan 20 is worn on the user's body, the fan 22 can be started to drive the air flow out of the air outlet 21a to dissipate heat for the user. The position of the air inlet of the shell assembly 21 can have various variations. For example, the air inlet can be located on the side of the shell assembly 21 away from the air outlet 21a, or it can be located on the circumference of the shell assembly 21. This application does not impose any restrictions on this. In particular, in some embodiments, the fan 22 can use an air compressor such as a supercharged turbine to achieve a design without an impeller on the appearance of the wearable fan 20, that is, to achieve the effect of a bladeless fan 22, making the appearance of the wearable fan 20 more concise.

[0075] The power module 23 is disposed within the housing assembly 21 and is used to power the fan 22. The power module 23 of the wearable fan 20 typically includes a rechargeable battery, such as a lithium battery. With advancements in battery technology, battery capacity is increasing, and the battery life of the wearable fan 20 is also steadily improving.

[0076] The retractable wire module 24 is provided in the shell assembly 21 and includes a cable 241 that can be retracted relative to the shell assembly 21. The cable 241 can be stored in the shell assembly 21 and can be pulled out of the shell assembly 21 and docked to an external electronic device to power the external electronic device through the power module 23. In some embodiments, the cable 241 can be wound and stored in the shell assembly 21 to achieve a hidden effect of the cable 241, so that the wearable fan 20 maintains a relatively simple appearance and avoids the cable 241 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 241 of the retractable wire module 24 can be pulled out of the shell assembly 21 and docked to the external electronic device, and these external electronic devices are powered by the power module 23 of the wearable fan 20, for example, to charge a mobile phone.

[0077] refer to Figure 10In the second embodiment, 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 is not limited to a Type-C interface, or a Micro-USB interface, or a Lightning interface, or a magnetic charging interface, etc. 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, so it will not be described in detail.

[0078] When the user carries the wearable fan 20 and needs to charge it, the cable 241 of the retractable wire module 24 can be pulled out from the shell assembly 21 of the wearable fan 20 and connected to an external electronic device such as a mobile phone. The power module 23 of the wearable fan 20 can be used to power the external electronic device and realize the charging function, so there is no need to carry a mobile power supply and charging cable separately, which improves the 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 wearable fan 20 to power the external electronic device. When the user no longer needs to power the external electronic device through the wearable fan 20, the cable 241 of the retractable wire module 24 can be stored in the shell assembly 21, and the wearable fan 20 can still maintain a relatively simple appearance, which is convenient for the user to carry and improves the convenience of use.

[0079] The difference from the first embodiment is that the shell assembly 21 may include a shell 211 and a wearing piece 213 connected to the shell 211, the shell 211 has an air outlet 21a, and the fan 22, the power module 23 and the telescopic line module 24 are respectively arranged on the shell 211. The wearing piece 213 can be integrally formed with the shell 211, for example, by injection molding, thereby improving the efficiency of the shell assembly 21 processing and reducing the cost of the shell assembly 21. The wearing piece 213 can also be assembled and fixed with the shell 211. For example, it is fixed to the shell assembly 21 by fasteners such as screws, or by bonding, or by snap fasteners. The material of the wearing piece 213 can be the same as that of the shell 211, for example, both are plastic. Of course, the material of the wearing piece 213 can be different from that of the shell 211. For example, the shell 211 is made of plastic material, and the wearing piece 213 is made of metal material such as stainless steel or manganese steel, thereby improving the fatigue resistance and texture of the wearing piece 213.

[0080] refer to Figure 8The wearing member 213 may include an integrally formed fixing portion 2131, a deforming portion 2133, and an abutting portion 2135. The fixing portion 2131 is fixedly connected to the housing 211, for example, by injection molding or bonding. The deforming portion 2133 has an arc-shaped cross-section, with one end of the deforming portion 2133 connected to the fixing portion 2131 and the other end of the deforming portion 2133 connected to the abutting portion 2135. The abutting portion 2135 is inclined toward the housing 211 from the end of the deforming portion 2133 away from the fixing portion 2131. Taking the example of a user wearing the wearable fan 20 to the collar, the abutment portion 2135 can be inserted between the user's collar and the body, and the collar will support the end of the abutment portion 2135 away from the deformation portion 2133 away from the shell 211, providing space for the entry of the collar. During this process, the deformation portion 2133 produces elastic deformation; the collar continues to penetrate between the abutment portion 2135 and the shell 211 until it abuts the deformation portion 2133, and the end of the abutment portion 2135 away from the deformation portion 2133 can press the shell 211 or press the shell 211 through the collar or clothing, thereby restricting the collar between the wearing piece 213 and the shell 211, thereby reliably wearing the wearable fan 20 on the body.

[0081] In other embodiments, the wearing member 213 may be rotatably connected to the housing 211, for example, by screws, bolts, or other rotating shaft structures. For example, the fixing portion 2131 of the wearing member 213 may be rotatably connected to the housing 211, and the relative rotation between the two may have appropriate damping. When the user hangs the wearable fan 20 on a collar or other location via the wearing member 213, the housing 211 may be rotated relative to the wearing member 213 to adjust the direction of the air outlet 21a, thereby improving user convenience.

[0082] The housing 211 may be provided with a snap-fit ​​structure (not shown) and an opening for the cable 241 to extend and retract. The snap-fit ​​structure is used to snap-fit ​​with one end of the cable 241 extending out of the housing 211 to form a ring structure for hanging on a human body, such as Figure 11As shown. For example, the housing 211 may be provided with a card slot (not shown), and a card plate (not shown) that slides with the housing 211. After the user pulls out the cable 241 housed in the housing 211, the free end of the cable 241 can be extended into the card slot, and then the card plate is pushed to cover the card slot, and the cable 241 is engaged with the housing 211. The cable 241 thus forms a ring structure for hanging on the human body. The user can hang the wearable fan 20 around the neck through the ring structure, or put the hand through the ring structure, so that the air can be blown toward the face or other directions, thereby improving the convenience of using the wearable fan 20 and expanding the use scenarios of the wearable fan 20. After the user retracts the card plate, the free end of the cable 241 can be unlocked from the housing 211 again, and then retracted into the housing 211 normally. The snap-fit ​​structure may also have other forms, for example, the housing 211 may be provided with an openable and closable buckle. After the buckle is opened, the free end of the cable 241 may be inserted. After the buckle is closed, the free end of the cable 241 may also be clamped to the housing 211, thereby forming a ring structure for hanging on the human body.

[0083] Continue to refer Figure 8 and Figure 9 In some embodiments, the wearing piece 213 is fixedly connected to the housing 211. The housing 211 may include a first shell 2111 connected to a second shell 2113 of the first shell 2111, and the first shell 2111 and the second shell 2113 may be in the shape of an oblate spherical shell. The fan 22 is mounted on the first shell 2111, and the first shell 2111 has an air outlet 21a. The power module 23 and the telescopic line module 24 are provided on the second shell 2113. The first shell 2111 can rotate relative to the second shell 2113 to adjust the direction of the air outlet 21a. For example, the relative rotation between the first shell 2111 and the second shell 2113 has appropriate damping. When the user hangs the wearable fan 20 on a collar or other location through the wearing piece 213, the first shell 2111 can be driven to rotate relative to the second shell 2113 to adjust the direction of the air outlet 21a, thereby improving the convenience of use.

[0084] Furthermore, the rotation axis of the fan 22 can be parallel to the rotation axis of the second shell 2113 relative to the first shell 2111. The fan 22 can be a radial fan 22, which discharges air from the side of the first shell 2111. This wearable fan 20 can have a smaller overall thickness, improving its compactness and portability.

[0085] Similar to the first embodiment, the wearable fan 20 may also include a circuit board 25 disposed within the second shell 2113. The retractable cable module 24 includes a cover 242 disposed within the outer shell 211. The fan 22 and the power module 23 are each electrically connected to the circuit board 25. The cover 242 and the circuit board 25 are relatively fixed in position, and the cable 241 is retractably disposed within the cover 242. The circuit board 25 may integrate the control circuitry, power management unit, and other components of the wearable fan 20. The power module 23, fan 22, and cable 241 are each electrically connected to the circuit board 25. Components such as the fan 22's start / stop button and speed adjustment knob may be configured to correspond to the control circuitry on the circuit board 25 to achieve corresponding functions. This will not be further described.

[0086] The cover 242 can be fixedly connected to the circuit board 25 or to the second shell 2113, thereby securing the cover 242 relative to the circuit board 25. The retractable cable module 24, including the cover 242, can be manufactured as a separate module and assembled into the wearable fan 20, thereby improving assembly efficiency and ensuring the reliability of the retractable cable module 24.

[0087] Specifically, the telescopic cable module 24 may include a circuit board 243, a torsion spring 244, and a rotating disk 245 disposed within a housing 242. The circuit board 243 is fixed relative to the housing 242, for example, fixedly connected to the housing 242 or the second shell 2113 of the housing assembly 21. The circuit board 243 is electrically connected to the circuit board 25, for example, by wire bonding. The torsion spring 244 may be helical and have a first free end 2441 and a second free end 2443. The first free end 2441 of the torsion spring 244 is connected to the rotating disk 245, while the second free end 2443 is fixed relative to the circuit board 243, for example, fixedly connected to the housing 242 or the circuit board 243. The rotating disk 245 is rotatably connected to the housing 242, for example, by providing a rotating shaft on one of the two, and a shaft hole on the other, thereby achieving the rotatable connection between the rotating disk 245 and the housing 242. Cable 241 is wound around the periphery of torsion spring 244. One of circuit board 243 and turntable 245 is provided with a contact pin (not shown), while the other is provided with a ring conductor (not shown). The contact pin contacts and the ring conductor, electrically connecting cable 241 to the contact pin or the ring conductor on turntable 245, thereby achieving electrical connection between cable 241 and circuit board 243. For example, circuit board 243 may be provided with a contact pin, and turntable 245 may be provided with a ring conductor, and cable 241 may be electrically connected to the ring conductor; or circuit board 243 may be provided with a ring conductor and turntable 245 may be provided with a contact pin, and cable 241 may be electrically connected to the contact pin, thereby achieving electrical connection between cable 241 and circuit board 243. Of course, cable 241 may also be directly electrically connected to circuit board 243 through methods such as wire soldering.

[0088] The cable 241 can be clamped to the rotating disc 245, and during the process of pulling the cable 241 by the user, the rotating disc 245 is driven to rotate relative to the shell 242 in a direction, for example, the clockwise direction, to gradually extend out of the shell 242, and in this process, the contact pin keeps in contact with the annular conductor, thereby ensuring the electrical connection between the cable 241 and the circuit board 25. In this process, the torsional spring 244 accumulates elastic potential energy, so that the rotating disc 245 has a tendency to rotate in the counterclockwise direction. When the user no longer needs to power the external electronic device through the wearable fan 20, the torsional spring 244 can release the elastic potential energy, and drive the cable 241 extending out of the shell 242 to gradually wind into the shell 242.

[0089] Meanwhile, in combination with Figure 12 In some embodiments, the telescopic cable module 24 includes a clamping block 246 rotationally connected to the shell 242, and the rotating disc 245 has a clamping position 2451 and an unlocking position 2453. During the process of pulling the cable 241 out of the shell 242, when the rotating disc 245 is driven to rotate to the clamping position 2451 corresponding to the clamping block 246, the clamping block 246 limits the rotation of the rotating disc 245; when the cable 241 continues to pull out of the shell 242 and drives the rotating disc 245 to rotate, the clamping block 246 rotates relative to the shell 242 and moves to the unlocking position 2453, so that the cable 241 can be gradually wound into the shell 242. Figure 12 The dashed line shows the movement track of the end clamping point of the clamping block 246 in the clamping position 2451 and the unlocking position 2453. By setting corresponding limiting grooves 245a and guide grooves 245b on the rotating disc 245, the groove wall of the limiting groove 245a can be used as the clamping position 2451, and the connecting position of the groove wall of the guide groove 245b and the groove wall of the limiting groove 245a is the unlocking position 2453.

[0090] When the user pulls the cable 241 out of the shell 242 and rotates the rotating disc 245, the end of the clamping block 246 moves to the clamping position 2451 along the guide groove 245b, at this time, if the user does not continue to pull the cable 241, the end of the clamping block 246 abuts against the groove wall of the limiting groove 245a under the action of the torsion spring 244, the rotating disc 245 no longer continues to rotate, that is, the cable 241 can be clamped and stopped; when the user continues to pull the cable 241 out of the shell 242 and rotates the rotating disc 245, the clamping block 246 rotates relative to the shell 242 and retreats to the guide groove 245b, and can be switched to the guide groove 245b to continue to move along the guide groove 245b, that is, to the unlocking position 2453, the rotating disc 245 can continue to rotate and make the cable 241 continuously extend out of the shell 242, or the cable 241 can be gradually wound into the shell 242. The cooperation of the clamping block 246 and the rotating disc 245 can realize the clamping and automatic winding of the cable 241, and improve the convenience of use. Moreover, the rotating disc 245 can be provided with two or more clamping positions 2451 and unlocking positions 2453, and the clamping positions 2451 and the unlocking positions 2453 can be one-to-one corresponding.

[0091] Of course, in other embodiments, other structures can be used to replace the clamping block 246 to clamp the cable 241, for example, the wearable fan 20 can include a limiting piece (not shown) movably fitted in the second shell 2113, the limiting piece has a first position and a second position, when the cable 241 can be pulled out or retracted into the second shell 2113 in the first position; in the second position, the limiting piece abuts against the cable 241 and limits the movement of the cable 241 relative to the second shell 2113.

[0092] Exemplarily, the limiting piece is slidingly fitted with the second shell 2113, and the sliding of the limiting piece and the second shell 2113 has appropriate damping to avoid easy retreat of the limiting piece. In the process of pulling out the cable 241 by the user, when the cable 241 needs to be clamped, the limiting piece is pushed to slide relative to the second shell 2113 to the position of abutting against the cable 241, that is, the second position, so that the cable 241 can be clamped in the second shell 2113; when the user needs to retract the cable 241 into the second shell 2113, the limiting piece is pushed in the opposite direction to the first position, and the limiting piece no longer abuts against the cable 241, so that the cable 241 can be wound into the shell 242 under the action of the torsion spring 244 and the rotating disc 245.

[0093] For example, the stopper is rotatably engaged with the second shell 2113. 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 241 during the process of pulling out the cable 241, the stopper is rotated so that the eccentric wheel of the stopper presses against the cable 241, i.e., reaches the second position, thereby stopping the cable 241 in the second shell 2113. When the user needs to retract the cable 241 into the second shell 2113, the stopper is rotated in the opposite direction to the first position. After the eccentric wheel of the stopper no longer presses against the cable 241, the cable 241 can be rewound into the cover 242 under the action of the torsion spring 244 and the rotating disk 245.

[0094] The above two limiting member structures can achieve the cable 241 to stop, and combined with the torsion spring 244, 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 241 to stop effect.

[0095] It is understood that the housing 242 of the retractable cable module 24 is optional and can be omitted to simplify the structure of the wearable fan 20 and improve its compactness. For example, the retractable cable module 24 includes a torsion spring 244 and a turntable 245. The first free end 2441 of the torsion spring 244 is connected to the turntable 245, and the second free end 2443 of the torsion spring 244 is fixed relative to the circuit board 25. The cable 241 is wound around the periphery of the torsion spring 244 and electrically connected to the circuit board 25 directly, such as by soldering or wire bonding, or by contact pins and a ring conductor. The cable 241 is retained by the turntable 245. When the user pulls the cable 241, the turntable 245 rotates in a direction, such as clockwise, relative to the second housing 2113, gradually extending out of the second housing 2113. During this process, the torsion spring 244 accumulates elastic potential energy, causing the turntable 245 to tend to rotate counterclockwise. When the user no longer needs to power the external electronic device through the wearable fan 20 , the torsion spring 244 releases elastic potential energy, driving the cable 241 extending outside the second shell 2113 to gradually reel into the second shell 2113 .

[0096] In this embodiment, the telescopic cable module 24 may also include a clamping block 246, and the turntable 245 has a locking position 2451 and an unlocking position 2453. When the cable 241 is pulled out of the second shell 2113, the cable 241 drives the turntable 245 to rotate to the locking position 2451 corresponding to the clamping block 246, and the clamping block 246 restricts the rotation of the turntable 245; when the cable 241 continues to be pulled out of the second shell 2113 and drives the turntable 245 to rotate, the clamping block 246 moves relative to the turntable 245 to the unlocking position 2453, so that the cable 241 is gradually reeled into the second shell 2113. The principle and structure of the clamping block 246 for locking the cable 241 and the principle and structure of the unlocking of the cable 241 can be referred to the above content and will not be repeated here. The cooperation of the above clamping block 246 and the turntable 245 can realize the locking of the cable 241, and combined with the torsion spring 244, an automatic reeling effect can be achieved, thereby improving the convenience of use.

[0097] Of course, in this embodiment, the wearable fan 20 may also include a limiter that is movably engaged with the second shell 2113, and 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 second shell 2113; in the second position, the limiter abuts the cable 241 and limits the movement of the cable 241 relative to the second shell 2113. The principle and structure of the cable 241 being stopped by the limiter, as well as the principle and structure of unlocking, 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 241, and combined with the torsion spring 244, 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 241.
