[0035] First Embodiment

[0036] Reference Figure 1 、 Figure 2 and Figure 3 , and in combination with Figure 4 , the first embodiment of the present application discloses a portable fan 10, which comprises a shell assembly 100, a fan 200, a power module 300 and a flexible wire module 400. The shell assembly 100 is used to provide support for the entire structure, and is provided with an outlet 100a and an air outlet 100b. The fan 200 is arranged in the shell assembly 100 and blows air from the air outlet 100b. In some embodiments, the fan 200 is an axial fan. In other embodiments, the fan 200 can be a centrifugal fan. In other embodiments, the fan 200 can also use an air compressor such as a turbocharger to achieve a portable fan 10 design without impeller on the appearance, that is, to achieve the effect of a bladeless fan 200, so that the appearance of the portable fan 10 is more simple and concise.

[0037] In some embodiments, as shown in Figure 1 and Figure 2 , the portable fan 10 is a handheld fan, the shell assembly 100 comprises an air outlet part 110 and a holding part 120 connected to the air outlet part 110. The air outlet part 110 has an air outlet 100b, the fan 200 is arranged in the air outlet part 110, and the power module 300 and the flexible wire module 400 are arranged in the holding part 120. One of the air outlet part 110 and the holding part 120 has an outlet 100a. Of course, in other embodiments, the fan 200 can be arranged in the holding part 120, and the power module 300 and the flexible wire module 400 can also be arranged in the air outlet part 110. The user can hold the holding part 120 of the portable fan 10 and direct the air outlet 100b towards some parts of the body such as the face or the neck, etc. for blowing and heat dissipation.

[0038] In other embodiments, referring to Figure 5 and Figure 6 , the portable fan 10 can comprise a wearing part 500 connected to the shell assembly 100, which is used to be worn on the user's body. In some embodiments, the wearing part 500 is a curved hardware with a free end that can be driven to open and close relative to the shell assembly 100, and can be used to wear the portable fan 10 on the waistband or backpack strap, etc. The portable fan 10 in this embodiment is typically a waist-mounted fan, a clip fan, etc.

[0039] Referring to Figure 7 and Figure 8In other embodiments, the shell assembly 100 can also form a space for wearing to the user's body, for example, the shell assembly 100 forms an open ring, and the user can wear such a portable fan 10 on the neck, Figure 7 The portable fan 10 shown can also be referred to as a neck fan 200.

[0040] The present application is described by way of example of a handheld fan, and adaptive deformation can be made for other types of portable fans 10, which should not be excluded from the protection scope of the present application.

[0041] Continuing to refer to Figure 2 The power module 300 is provided in the shell assembly 100 and is used to power the fan 200. The power module 300 of the portable fan 10 generally includes a battery that can be repeatedly charged and discharged, such as a lithium battery. With the advancement of battery technology, the capacity of the battery is constantly increasing, and the endurance performance of the portable fan 10 is also steadily improving. Further, the portable fan 10 can include a circuit board 600 provided in the shell assembly 100. The fan 200, the power module 300, and the flexible wire module 400 are respectively electrically connected to the circuit board 600. The circuit board 600 can integrate a control circuit of the fan 200 and a power management unit, etc. The shell assembly 100 can also be provided with buttons, rotating wheels, and other structures. Such structures are provided in correspondence with triggering structures on the circuit board 600, and are used to control the start and stop of the fan 200, or adjust the speed of the fan 200, etc. The buttons are not limited to physical buttons, and can also be virtual buttons, such as virtual buttons presented by a touch screen.

[0042] Meanwhile referring to Figure 3 The flexible wire module 400 is provided in the shell assembly 100 and includes a wire body 410 and a docking head 420 connected to one end of the wire body 410. The wire body 410 is electrically connected to the circuit board 600, and the width of the docking head 420 is not greater than the width of the wire outlet 100a. The wire body 410 can be retracted into the wire outlet 100a to be accommodated in the shell assembly 100, or extended out of the shell assembly 100 to dock the docking head 420 to an external electronic device, and power the external electronic device through the power module 300. In some embodiments, the wire body 410 can be wound and accommodated in the shell assembly 100 to achieve a hiding effect of the wire body 410, so that the portable fan 10 maintains a relatively simple appearance and avoids inconvenience to the user in daily use. When the user needs to power a mobile phone or other external electronic device, the wire body 410 of the flexible wire module 400 can be pulled out of the shell assembly 100 and docked to the external electronic device through the docking head 420. The power module 300 of the portable fan 10 is used to power these external electronic devices, such as charging a mobile phone. The docking head 420 is not limited to a Type-C interface, or a Micro-USB interface, or a Lightning interface, or a magnetic charging interface, etc., which will not be described here.

[0043] In the embodiments of the present application, the width of the joint 420 is not greater than the width of the outlet 100a, which can be understood as the cross-sectional area of the joint 420 is not greater than the cross-sectional area of the outlet 100a, so that the joint 420 can be extended from the outlet 100a in the assembly process, so that the joint 420 is extended outside the shell assembly 100 after the telescopic line module 400 is assembled in the shell assembly 100, ensuring the smoothness of the assembly of the telescopic module and the shell assembly 100. It can be understood that the width of the outlet 100a is equal to or slightly greater than the width of the joint 420, or the cross-sectional area of the outlet 100a is equal to or slightly greater than the cross-sectional area of the joint 420, so as to prevent the shell assembly 100 from opening a too large outlet 100a and causing great damage to the overall appearance of the shell assembly 100.

[0044] Reference Figure 3 The telescopic line module 400 can include a cover 430 provided in the shell assembly 100 (for example, the holding portion 120), the cover 430 is relatively fixed with the position of the power module 300, and the line body 410 is telescopically provided in the cover 430. The cover 430 can be fixedly connected to the circuit board 600, or can be fixedly connected to the shell assembly 100, so as to realize the relative fixation of the position of the cover 430 and the circuit board 600. The telescopic line module 400 including the cover 430 can be made into an independent module and assembled into the shell assembly 100, so as to improve the efficiency of assembly and ensure the reliability of the work of the telescopic line module 400.

[0045] The telescopic wire module 400 can include a circuit board 440, a torsion spring 450 and a rotating disc 460 arranged in the shell 430. The circuit board 440 is fixed relative to the shell 430, for example, fixedly connected to the shell 430 or the shell assembly 100, and electrically connected to the circuit board 600, for example, by wire bonding. The torsion spring 450 can be in the shape of a spiral and one end thereof is fixed relative to the shell 430 and the other end thereof is fixed relative to the rotating disc 460. The rotating disc 460 is rotatably connected to the shell 430, for example, one of the rotating disc 460 and the shell 430 is provided with a rotating shaft and the other is provided with a shaft hole matched with the rotating shaft. The wire body 410 is arranged around the outer periphery of the torsion spring 450, one of the circuit board 440 and the rotating disc 460 is provided with a contact pin (not shown) and the other is provided with a ring conductor (not shown), the contact pin is in contact with the ring conductor, the wire body 410 is electrically connected to the contact pin or the ring conductor on the rotating disc 460, thereby realizing the electrical connection between the wire body 410 and the circuit board 440. For example, the circuit board 440 is provided with the contact pin and the rotating disc 460 is provided with the ring conductor, the wire body 410 is electrically connected to the ring conductor; or the circuit board 440 is provided with the ring conductor and the rotating disc 460 is provided with the contact pin, the wire body 410 is electrically connected to the contact pin, thereby realizing the electrical connection between the wire body 410 and the circuit board 440. Of course, the wire body 410 can be directly electrically connected to the circuit board 440 by wire bonding or the like.

[0046] The wire body 410 can be clamped to the rotating disc 460 and in the process of being pulled by the user, the wire body 410 drives the rotating disc 460 to rotate relative to the shell 430 in one direction, for example, clockwise, to gradually extend out of the shell 430, in the process, the contact pin keeps in contact with the ring conductor, thereby ensuring the electrical connection between the wire body 410 and the circuit board 600. In the process, the torsion spring 450 accumulates elastic potential energy, so that the rotating disc 460 has a tendency to rotate counterclockwise. When the user no longer needs to supply power to the external electronic device by the portable fan 10, the torsion spring 450 can release the elastic potential energy and drive the wire body 410 extending out of the shell 430 to gradually wind into the shell 430.

[0047] Meanwhile, in combination with Figure 4 In some embodiments, the telescopic wire module 400 includes a clamping block 470 rotatably connected to the shell 430, the rotating disc 460 has a clamping position 461 and an unlocking position 463, in the process of being pulled out of the shell 430, when the wire body 410 drives the rotating disc 460 to rotate to the clamping position 461 corresponding to the clamping block 470, the clamping block 470 limits the rotation of the rotating disc 460; when the wire body 410 continues to be pulled out of the shell 430 and drives the rotating disc 460 to rotate, the clamping block 470 rotates relative to the shell 430 and moves to the unlocking position 463, so that the wire body 410 can be gradually wound into the shell 430. Figure 4The rotary disc 460 is provided with corresponding limiting grooves 460a and guide grooves 460b. The groove wall of the limiting groove 460a can be used as the clamping stop position 461, and the connecting position of the groove wall of the guide groove 460b and the groove wall of the limiting groove 460a is the unlocking position 463.

[0048] The side wall of the guide groove 460b can guide and limit the movement of the end of the clamping block 470, so that the wire body 410 continuously moves along the guide groove 460b during the pulling-out process, and when the user stops pulling out the wire body 410, the rotary disc 460 is driven to rotate reversely (for example, clockwise) by the torsional spring 450, the end of the clamping block 470 is guided into the limiting groove 460a by the side wall of the guide groove 460b, and the clamping of the wire body 410 is achieved; when the user continues to pull out the wire body 410, the rotary disc 460 continues to rotate in the original direction (for example, counterclockwise), the end of the clamping block 470 exits the limiting groove 460a and enters the guide groove 460b, and the wire body 410 can continue to be pulled out. It can be understood that the above functions can be achieved by designing the depth and width of the guide groove 460b and the limiting groove 460a, and the application will not be described in detail.

[0049] When the user pulls out the wire body 410 from the shell 430 and drives the rotary disc 460 to rotate, the end of the clamping block 470 moves to the clamping stop position 461 along the guide groove 460b. At this time, if the user does not continue to pull out the wire body 410, the end of the clamping block 470 is abutted against the groove wall of the limiting groove 460a under the action of the torsional spring 450, the rotary disc 460 no longer continues to rotate, and the clamping of the wire body 410 is achieved; when the user continues to pull out the wire body 410 from the shell 430 and drives the rotary disc 460 to rotate, the clamping block 470 rotates relative to the shell 430 and retreats to the guide groove 460b, and can switch to the guide groove 460b to continue to move along the guide groove 460b, that is, to reach the unlocking position 463, the rotary disc 460 can continue to rotate and make the wire body 410 continuously extend out of the shell 430, or the wire body 410 can be gradually wound into the shell 430. The cooperation of the clamping block 470 and the rotary disc 460 can achieve the clamping and automatic winding of the wire body 410, and improve the convenience of use. Moreover, the rotary disc 460 can be provided with two or more clamping stop positions 461 and unlocking positions 463, and the clamping stop positions 461 and the unlocking positions 463 can be one-to-one corresponding.

[0050] Of course, in other embodiments, other structures can be used to replace the clamping block 470 to clamp the wire body 410, for example, the portable fan 10 can include a limiting piece (not shown) movably matched with the shell assembly 100, the limiting piece has a first state and a second state, in the first state, the wire body 410 can be pulled out or retracted into the shell assembly 100; in the second state, the limiting piece abuts against the wire body 410 and limits the movement of the wire body 410 relative to the shell assembly 100.

[0051] Exemplarily, the limiting member is in sliding fit with the shell assembly 100, and the sliding of the limiting member with the shell assembly 100 has appropriate damping, avoiding easy back-off of the limiting member. In the process of pulling out the wire body 410 by the user, when it is needed to stop the wire body 410, the limiting member is pushed to slide relative to the shell assembly 100 to abut against the wire body 410 to the position of the second state, so that the wire body 410 can be stopped in the shell assembly 100; when the user needs to collect the wire body 410 into the shell assembly 100, the limiting member is pushed to the first state in the opposite direction, and the limiting member no longer abuts against the wire body 410, so that the wire body 410 can be rewound into the cover shell 430 under the action of the torsional spring 450 and the rotating disc 460.

[0052] Exemplarily, the limiting member is in rotating fit with the shell assembly 100, and the limiting member can have an eccentric wheel structure and appropriate rotating damping, preventing easy back-off of the limiting member. In the process of pulling out the wire body 410 by the user, when it is needed to stop the wire body 410, the limiting member is rotated, so that the eccentric wheel of the limiting member abuts against the wire body 410 to the second state, so that the wire body 410 can be stopped in the shell assembly 100; when the user needs to collect the wire body 410 into the shell assembly 100, the limiting member is rotated to the first state in the opposite direction, and the eccentric wheel of the limiting member no longer abuts against the wire body 410, so that the wire body 410 can be rewound into the cover shell 430 under the action of the torsional spring 450 and the rotating disc 460.

[0053] The structures of the above two limiting members can both achieve the stopping of the wire body 410, and the automatic rewinding effect can be achieved in combination with the torsional spring 450, improving the convenience of use. In other embodiments, the limiting member can also have other structural forms, and the stopping effect on the wire body 410 can be achieved.

[0054] It can be understood that the cover 430 of the retractable wire module 400 is not necessary, and can be omitted to simplify the structure of the portable fan 10 and improve the compactness of the portable fan 10. For example, the retractable wire module 400 includes a torsion spring 450 and a rotating disc 460 rotatably connected to the shell assembly 100 or the circuit board 600, one free end of the torsion spring 450 is connected to the rotating disc 460, the other free end of the torsion spring 450 is fixed relative to the position of the circuit board 600, the wire body 410 is arranged on the outer periphery of the torsion spring 450 and is directly electrically connected to the circuit board 600, for example, soldering or combined with wire bonding, or the electrical connection between the wire body 410 and the circuit board 600 is realized through a contact pin and a ring conductor. The wire body 410 can be clamped to the rotating disc 460, and in the process of the user pulling the wire body 410, the rotating disc 460 is driven to rotate relative to the shell assembly 100 in one direction, for example, a clockwise direction, to gradually extend out of the shell assembly 100. In this process, the torsion spring 450 accumulates elastic potential energy, so that the rotating disc 460 has a tendency to rotate in the opposite direction, that is, counterclockwise. When the user no longer needs to power the external electronic device through the portable fan 10, the torsion spring 450 releases the elastic potential energy, and the wire body 410 extending out of the shell assembly 100 is gradually wound into the shell assembly 100.

[0055] In this embodiment, the retractable wire module 400 can also include a clamping block 470, and the rotating disc 460 has a clamping position 461 and an unlocking position 463. In the process of pulling the wire body 410 out of the shell assembly 100, when the wire body 410 drives the rotating disc 460 to rotate to the clamping position 461 corresponding to the clamping block 470, the clamping block 470 limits the rotation of the rotating disc 460. When the wire body 410 continues to be pulled out of the shell assembly 100 and drives the rotating disc 460 to rotate, the clamping block 470 moves relative to the rotating disc 460 to the unlocking position 463, so that the wire body 410 is gradually wound into the shell assembly 100. The clamping principle and structure of the clamping block 470 to the wire body 410 and the unlocking principle and structure can be referred to the foregoing content, which will not be described here. The cooperation of the clamping block 470 and the rotating disc 460 can realize the clamping of the wire body 410, and combined with the torsion spring 450, the automatic winding effect can be realized, improving the convenience of use.

[0056] Of course, in this embodiment, the portable fan 10 can also include a limiting piece movably matched with the shell assembly 100, and the limiting piece has a first state and a second state. In the first state, the wire body 410 can be pulled out of the shell assembly 100 or wound into the shell assembly 100. In the second state, the limiting piece abuts against the wire body 410 and limits the movement of the wire body 410 relative to the shell assembly 100. The clamping principle and structure of the limiting piece to the wire body 410 and the unlocking principle and structure can also be referred to the foregoing content, which will not be described here. The structure of the limiting piece can realize the clamping of the wire body 410, and combined with the torsion spring 450, the automatic winding effect can be realized, improving the convenience of use. In other embodiments, the limiting piece can also adopt other structural forms to realize the clamping effect of the wire body 410.

[0057] Referring to Figure 9 In some embodiments, the connector 420 has a first position and a second position relative to the housing assembly 100, in the first position the wire body 410 is received in the housing assembly 100 and the connector 420 is at least partially received in the outlet 100a. In the second position, the wire body 410 and the connector 420 extend out of the housing assembly 100 for connection to an external electronic device. In other words, in the first position, the connector 420 can partially protrude out of the outlet 100a, preventing the connector 420 from extending out of the housing assembly 100 too long and causing inconvenience to the user, and also allowing the user to hold the connector 420 with a finger and pull the connector 420 and the wire body 410 out of the housing assembly 100. Of course, in the first position, the connector 420 can also be fully received in the outlet 100a.

[0058] In combination Figure 10 And Figure 11 In such embodiments, the portable fan 10 can include an ejecting assembly 700 provided in the housing assembly 100, the ejecting assembly 700 being configured to be triggered to eject the connector 420 in the first position out of the housing assembly 100. Specifically, the ejecting assembly 700 can include a resilient member 710 provided in the housing assembly 100, and a slider 720 connected to the resilient member 710, in the process of switching the connector 420 from the second position to the first position, the connector 420 drives the slider 720 to move in the housing assembly 100 and be locked in the first position, and the resilient member 710 accumulates elastic potential energy, as shown in Figure 11 The slider 720 is configured to be triggered to be unlocked from the housing assembly 100, and the resilient member 710 drives the slider 720 to eject the connector 420 out of the housing assembly 100, as shown in Figure 10

[0059] Specifically, referring to Figure 10 And Figure 11 In some embodiments, the ejecting assembly 700 includes a mounting base 730 connected to the housing assembly 100, and a pull rod 740 rotatably connected to the mounting base 730 at one end, the slider 720 is slidingly fitted to the mounting base 730, one end of the resilient member 710 is connected to the mounting base 730, and the other end is connected to the slider 720, the other end of the pull rod 740 is slidingly fitted to the slider 720. In the process of the connector 420 being pressed into the outlet 100a and moving to the first position, the connector 420 drives the slider 720 to move relative to the mounting base 730 to engage the pull rod 740 with the slider 720 in the first position; when the pull rod 740 is engaged with the slider 720, the connector 420 is pushed inward along the outlet 100a, the pull rod 740 can be unlocked from the slider 720, and the resilient member 710 can push the connector 420 out of the outlet 100a through the slider 720.

[0060] ​Specifically, the sliding block 720 can be provided with a sliding groove 721, which includes an entry groove 721a, an engaging groove 721b and an exit groove 721c. The engaging groove 721b is in communication with the entry groove 721a and the exit groove 721c respectively, and the exit groove 721c is in communication with the entry groove 721a. The bottom wall of the entry groove 721a is provided with a plurality of steps so that the depth of the entry groove 721a increases from the entrance of the entry groove 721a to the position where the engaging groove 721b is located. The depth of the exit groove 721c is smaller than that of the engaging groove 721b, and the bottom wall of the exit groove 721c and the bottom wall of the engaging groove 721b are smoothly connected. The depth of the exit groove 721c is smaller than that of the entrance of the entry groove 721a, so as to avoid that the free end of the pull rod 740 is mistakenly pushed into the exit groove 721c at the entrance of the entry groove 721a. When the adapter 420 is pushed inward along the outlet 100a, the free end of the pull rod 740 is slid into the entry groove 721a from the entrance of the entry groove 721a, and slides along the extension direction of the entry groove 721a to slide into the engaging groove 721b. The pull rod 740 is engaged with the sliding block 720 in the engaging groove 721b, so as to lock the sliding block 720 in the mounting seat 730, and the adapter 420 reaches the first position. When the pull rod 740 is engaged with the sliding block 720, the adapter 420 is pushed inward along the outlet 100a, the pull rod 740 is slid into the exit groove 721c and slides along the extension direction of the exit groove 721c to the entrance of the entry groove 721a, and the elastic member 710 pushes the adapter 420 out of the outlet 100a through the sliding block 720.

[0061] The pop-out assembly 700, in the process of storing the wire body 410 into the shell assembly 100, the user pushes the adapter 420 into the outlet 100a, and the step structure formed by the height difference between the adapter 420 and the wire body 410 can push the sliding block 720 to move, and then the free end of the pull rod 740 is engaged with the engaging groove 721b. When the free end of the pull rod 740 is engaged with the engaging groove 721b, the adapter 420 reaches the first position, and the sliding block 720 is locked in the shell assembly 100. The user can conveniently put the portable fan 10 into a bag or a pocket, and prevent the adapter 420 from being directly hung outside the shell assembly 100 to adversely affect the convenience of use. When the adapter 420 is located at the first position, the shell assembly 100 can also protect the adapter 420 from being scratched or damaged due to accidental collision.

[0062] When the user needs to use the docking head 420 to supply power to the external electronic device, the docking head 420 is pushed into the outlet 100a, and the step structure formed by the height difference between the docking head 420 and the wire body 410 can push the slider 720 to continue to move into the shell assembly 100, so that the free end of the pull rod 740 moves out of the clamping groove 721b and moves to the exit groove 721c in the sliding groove 721; under the action of the restoring force of the elastic member 710, the slider 720 is driven to reset by the elastic member 710, thereby pushing the docking head 420 to move out of the outlet 100a, that is, the function of the docking head 420 popping out of the shell assembly 100 is realized. When the slider 720 resets to the initial position, it can be considered that the docking head 420 has moved to the second position, and the user can conveniently hold the docking head 420 and pull the wire body 410 out of the shell assembly 100, thereby docking the docking head 420 to the external electronic device to supply power to the external electronic device.

[0063] Reference Figure 12 In other embodiments, the slider 720 has an integrally formed body 723 and a stop portion 725, the elastic member 710 is connected to the body 723, and the ejection assembly 700 includes a mounting box 750 fixed relative to the position of the shell assembly 100 and a clamping jaw 760 movably arranged in the mounting box 750. In the process of switching the docking head 420 from the second position to the first position, the docking head 420 drives the slider 720 to move in the shell assembly 100 and makes the stop portion 725 pass the clamping jaw 760, and the clamping jaw 760 and the stop portion 725 are locked at the first position, thereby positioning the docking head 420 at the first position. The clamping jaw 760 can be driven to open to drive the stop portion 725 out of the clamping jaw 760 by the elastic member 710, and drive the slider 720 to eject the docking head 420 out of the shell assembly 100. The mounting box 750 can be provided with a spring or other structure inside, or the clamping jaw 760 can cooperate with a torsion spring 450 or other structure, so that the clamping jaw 760 has a tendency to keep closing, so as to reliably keep the stop portion 725 of the slider 720 in the clamping jaw 760 at the first position. By means of an exposed button or a pull cord or other structure, the clamping jaw 760 is driven to open, and the elastic member 710 can reset the slider 720, thereby pushing the docking head 420 out of the shell assembly 100 by the slider 720.

[0064] Reference Figure 13In some embodiments, the docking joint 420 can be located entirely outside the shell assembly 100 in a state where the docking joint 420 is not in use. The portable fan 10 can include a decorative ring 800 that is disposed through the wire outlet 100a and is limited to the shell assembly 100. The decorative ring 800 has a through hole for the wire body 410 to pass through, and the width of the through hole is smaller than the width of the docking joint 420. Alternatively, the cross-sectional area of the through hole is smaller than the cross-sectional area of the docking joint 420, and the through hole allows the wire body 410 to freely expand and contract, but limits the docking joint 420 from entering the shell assembly 100, and appropriately blocks the wire outlet 100a to prevent the excessively large wire outlet 100a from easily entering dust or liquid droplets, thereby achieving a certain waterproof and dustproof effect, and preventing the excessively large wire outlet 100a from damaging the overall appearance of the shell assembly 100, i.e., improving the overall appearance of the shell assembly 100.

[0065] In this embodiment, the decorative ring 800 can be in the form of an open ring. The open ring-shaped decorative ring 800, which is not limited to materials such as hardware (e.g., stainless steel), silicone, or rubber, can be conveniently sleeved on the outer periphery of the wire body 410. During the assembly process of the extension wire module 400 and the shell assembly 100, the docking joint 420 passes through the wire outlet 100a from the inside of the shell assembly 100 to the outside of the shell assembly 100. The decorative ring 800 sleeved on the wire body 410 can be moved to the position of the wire outlet 100a and riveted, adhered, or clamped and fixed on the shell assembly 100 at the wire outlet 100a, thereby ensuring the connection stability of the decorative ring 800 and the shell assembly 100. Of course, in other embodiments, the decorative ring 800 can be in the form of a circumferentially closed ring structure, and the material thereof can be a resilient silicone or rubber. By stretching the decorative ring 800, the decorative ring 800 can be deformed to be conveniently sleeved on the wire body 410 and achieve the limiting of the decorative ring 800 and the shell assembly 100 at the wire outlet 100a.

[0066] Further, with reference to Figure 13 In some embodiments, the shell assembly 100 has a sink 100c that is in communication with the wire outlet 100a. The wire outlet 100a is disposed on the bottom of the sink 100c, and the wire body 410 can be bent to limit the docking joint 420 in the sink 100c. For example, the portable fan 10 can include a magnetic member 900 that is connected to the shell assembly 100 and is disposed corresponding to the bottom of the sink 100c. The docking joint 420 has a matching member 421 that is used to magnetically match the magnetic member 900 to adsorb the docking joint 420 to the bottom of the sink 100c. Further, one of the thickness directions of the docking joint 420 can be attached to the bottom of the sink 100c. The surface has a relatively large area, and the depth of the sink 100c does not have to be too large to avoid excessively affecting the overall appearance of the shell assembly 100.

[0067] One of the magnetic attraction member 900 and the matching member 421 is a magnet, and the other is a magnet or a ferromagnetic metal member such as iron, cobalt, nickel and alloys thereof. By using the magnetic attraction cooperation of the magnetic attraction member 900 and the matching member 421, the butt joint 420 after the bending of the wire body 410 can be reliably limited in the sink 100c, avoiding the butt joint 420 from extending outside the shell assembly 100 and adversely affecting the normal use. Of course, it can be understood that it is easier to realize that the butt joint 420 is provided with a ferromagnetic metal member and the shell assembly 100 is provided with a magnet, for example, the outer periphery of the butt joint 420 is covered with a ferromagnetic metal member.

[0068] Of course, there are more than one way to limit the butt joint 420 in the sink 100c, for example, the slot wall of the sink 100c can have a clamping part for directly clamping and limiting the butt joint 420 in the sink 100c. In other words, in this embodiment, the side wall of the sink 100c or the two sides of the butt joint 420 can be provided with a clamping structure that can be extruded and deformed. During the process of pressing the butt joint 420 into the sink 100c, the clamping structure is deformed so that the butt joint 420 is clamped into the sink 100c. This way can also realize the reliable limitation of the butt joint 420 in the sink 100c, and when needed, the butt joint 420 can be easily taken out of the sink 100c, and the wire body 410 can be pulled out of the shell assembly 100.

[0069] The above portable fan 10, when the user carries the portable fan 10 and needs to charge, can pull out the wire body 410 of the telescopic wire module 400 from the shell assembly 100 of the portable fan 10, and butt joint 420 to the external electronic equipment such as mobile phone, through the power supply module 300 of the portable fan 10 to supply power to the external electronic equipment and realize the charging function, so as not to carry the mobile power supply and the charging wire additionally, improve the convenience of use. When the external electronic equipment does not have a charging battery, the user can also use the power supply module 300 of the portable fan 10 to supply power to the external electronic equipment. When the user no longer needs to supply power to the external electronic equipment through the portable fan 10, the wire body 410 of the telescopic wire module 400 can be stored in the shell assembly 100, and the portable fan 10 can still maintain a relatively simple appearance, which is convenient for the user to carry and improves the convenience of use. Since the width of the butt joint 420 is not greater than the width of the wire outlet 100a, during the assembly of the telescopic wire module 400 and the shell assembly 100, the butt joint 420 can be pulled out from the shell assembly 100, so as to ensure the smooth assembly of the telescopic wire module 400 and the shell assembly 100.

[0070] Second embodiment

[0071] Reference Figure 14 and Figure 15The second embodiment of the present application provides a portable fan 1000, which comprises a shell assembly 1100, a fan 1200, a power module 1300 and a retractable wire module 1400. The shell assembly 1100 comprises a first shell 1110 and a second shell 1120 connected to the first shell 1110, and the first shell 1110 and the second shell 1120 enclose an outlet 1100a. The fan 1200 is arranged in the shell assembly 1100 and the shell assembly 1100 has an outlet 1100b for the fan 1200 to blow air. The power module 1300 is arranged in the shell assembly 1100 and used to supply power to the fan 1200. The retractable wire module 1400 is arranged in the shell assembly 1100 and comprises a wire body 1410 and a connector 1420 connected to one end of the wire body 1410. The width of the connector 1420 is greater than the width of the outlet 1100a. The wire body 1410 can be retracted into the outlet 1100a to be accommodated in the shell assembly 1100, or extended out of the shell assembly 1100 to connect the connector 1420 to an external electronic device, and the external electronic device is powered by the power module 1300.

[0072] In the second embodiment, the fan 1200 can be an axial fan, a centrifugal fan or a turbocharger, which will not be described here. The portable fan 1000 of the second embodiment can be a handheld fan, as shown in Figure 14 As shown, the shell assembly 1100 comprises an air outlet part 1101 and a holding part 1102 connected to the air outlet part 1101, and the first shell 1110 and the second shell 1120 are configured as part or all of the holding part 1102. One of the air outlet part 1101 and the holding part 1102 has the outlet 1100a. The air outlet part 1101 has the outlet 1100b, the fan 1200 is arranged in the air outlet part 1101, and the power module 1300 and the retractable wire module 1400 are arranged in the holding part 1102. Of course, the fan 1200 can be arranged in the holding part 1102, and the power module 1300 and the retractable wire module 1400 can also be arranged in the air outlet part 1101. The user can hold the holding part 1102 of the portable fan 1000 and direct the outlet 1100b towards some parts of the body, such as the face or the neck, for blowing and heat dissipation.

[0073] The portable fan 1000 of the second embodiment can also comprise the wearing part 500 connected to the shell assembly 1100 as in the first embodiment, and the wearing part 500 is used to be worn on the user's body. That is, the portable fan 1000 of the second embodiment can also be a waist hanging fan or a clip fan, etc. Of course, the shell assembly 1100 of the portable fan 1000 of the second embodiment can also form a space for being worn on the user's body, for example, the shell assembly 1100 forms an open ring shape, and the user can wear such a portable fan 1000 on the neck, that is, the portable fan 1000 of the second embodiment can also be a neck hanging fan, which will not be described here.

[0074] The second embodiment also takes the handheld fan as an example for illustration, and adaptive deformation can be made for other types of portable fans 1000, which should not be excluded from the protection scope of the present application.

[0075] The power module 1300 is arranged in the shell assembly 1100 and is used to supply power for the fan 1200. The power module 1300 of the portable fan 1000 generally includes a battery such as a lithium battery that can be repeatedly charged and discharged. With the advancement of battery technology, the capacity of the battery is constantly increasing, and the endurance performance of the portable fan 1000 is also steadily improved. Further, the portable fan 1000 can include a circuit board 1600 arranged in the shell assembly 1100. The fan 1200, the power module 1300, and the wire body 1410 are electrically connected to the circuit board 1600. The circuit board 1600 can integrate a control circuit of the fan 1200 and a power management unit, etc. The shell assembly 1100 can also be provided with a button, a rotary knob, etc. Such structures are arranged in correspondence with triggering structures on the circuit board 1600, and are used to control the start and stop of the fan 1200, or adjust the rotation speed of the fan 1200, etc. The button is not limited to a physical button, but can also be a virtual button, such as a virtual button presented by a touch screen.

[0076] In some embodiments, the wire body 1410 can be wound and stored in the shell assembly 1100 to achieve a hiding effect of the wire body 1410, so that the portable fan 1000 maintains a relatively simple appearance and avoids inconvenience caused to users in daily use by the wire body 1410. When the user needs to supply power to an external electronic device such as a mobile phone, the wire body 1410 of the telescopic wire module 1400 can be pulled out from the shell assembly 1100 and connected to the external electronic device through the connector 1420, and the power module 1300 of the portable fan 1000 is used to supply power to these external electronic devices, such as charging the mobile phone. The connector 1420 is not limited to a Type-C interface, or a Micro-USB interface, or a Lightning interface, or a magnetic charging interface, etc., which will not be described here.

[0077] The structure and working principle of the telescopic wire module 1400 of the second embodiment of the present application can refer to the first embodiment. The telescopic wire module 1400 of the first embodiment can be applied to the second embodiment by adaptive deformation, which will not be described here.

[0078] Different from the first embodiment, the shell assembly 1100 of the portable fan 1000 of the second embodiment can comprise a first shell 1110 and a second shell 1120 assembled separately, or in other words, the first shell 1110 and the second shell 1120 have a parting surface, and the two are assembled to form the wire outlet 1100a. The width of the wire outlet 1100a can be smaller than the width of the connector 1420, for example, the cross-sectional area of the wire outlet 1100a is smaller than the cross-sectional area of the connector 1420, and the cross-sectional area of the wire outlet 1100a can be comparable to the cross-sectional area of the wire body 1410 so that the wire body 1410 can be extended out of the shell assembly 1100. In other words, in this embodiment, the width of the wire outlet 1100a is not required to be greater than or equal to the width of the connector 1420, and the wire outlet 1100a can be relatively small to reduce the damage to the overall appearance of the shell assembly 1100, while reducing the probability of dust and liquid droplets entering the shell assembly 1100 from the wire outlet 1100a. In this embodiment, the first shell 1110 and the second shell 1120 can be assembled by abutting, for example, buckling or clamping or bonding, to form the wire outlet 1100a. During the assembly of the telescopic wire module 1400 and the shell assembly 1100, the wire body 1410 is only required to be arranged at the wire outlet 1100a, and the first shell 1110 and the second shell 1120 are abutted to be assembled, thereby ensuring the smooth assembly of the telescopic wire module 1400 and the shell assembly 1100, and improving the assembly efficiency.

[0079] Reference Figure 15 In some embodiments, the first shell 1110 has a first notch 1111, and the second shell 1120 has a second notch 1121, and the first notch 1111 and the second notch 1121 are abutted to form the wire outlet 1100a. In this embodiment, the first notch 1111 and the second notch 1121 can be mirror-symmetrically arranged with respect to the parting surface to obtain a more coordinated appearance of the shell assembly 1100. In other embodiments, the length of the first notch 1111, or the distance between the end of the first notch 1111 and the parting surface, can be greater than the length of the second notch 1121, or even the second notch 1121 can be omitted, that is, the second shell 1120 can be abutted with the first shell 1110 at the straight edge of the parting surface to form the wire outlet 1100a, and realize the smooth assembly of the telescopic wire module 1400 in the shell assembly 1100.

[0080] When the user carries the portable fan 1000 and needs to charge, the wire body 1410 of the telescopic wire module 1400 can be pulled out of the shell assembly 1100 of the portable fan 1000, and the connector 1420 can be connected to an external electronic device such as a mobile phone, so that the external electronic device is powered by the power supply module 1300 of the portable fan 1000 to realize the charging function, thereby eliminating the need to carry a separate power bank and charging cable, and improving the convenience of use. When the external electronic device does not have a charging battery, the user can also use the power supply module 1300 of the portable fan 1000 to power the external electronic device. When the user no longer needs to power the external electronic device through the portable fan 1000, the wire body 1410 of the telescopic wire module 1400 can be stored in the shell assembly 1100, and the portable fan 1000 can still maintain a relatively simple appearance, be convenient for the user to carry, and improve the convenience of use. Since the width of the connector 1420 is greater than the width of the wire outlet 1100a, the first shell 1110 and the second shell 1120 enclose the wire outlet 1100a, and in the assembly process of the telescopic wire module 1400 and the shell assembly 1100, the wire body 1410 is arranged at the wire outlet 1100a between the first shell 1110 and the second shell 1120, and then the first shell 1110 and the second shell 1120 are assembled and fixed, so that the telescopic wire module 1400 and the shell assembly 1100 can be smoothly assembled.

[0081] Of course, in the second embodiment of the present application, the portable fan 1000 can also include a decorative ring 800 similar to the first embodiment, which is arranged in the wire outlet 1100a and fixedly connected to the first shell 1110 and the second shell 1120. The decorative ring 800 can be made of metal such as stainless steel, or non-metal such as rubber or silicone, and the wire body 1410 is arranged in the decorative ring 800. In the case where the width of the wire outlet 1100a is less than the width of the connector 1420, the decorative ring 800 can still play a good decorative role, prevent the wire outlet 1100a from being too wide to damage the overall appearance of the shell assembly 1100, and play a better waterproof and dustproof effect, and the material can be used to reduce the abrasion or wear of the wire body 1410 and the first shell 1110 or the second shell 1120 caused by direct friction, for example, the decorative ring 800 contains self-lubricating materials or a smooth surface to reduce the wear of the wire body 1410.

[0082] Of course, in the second embodiment, the first housing 1110 and the second housing 1120 can also enclose the sink 1100c in communication with the outlet, and the outlet 1100a is arranged at the bottom of the sink 1100c, and the wire body 1410 can be bent to limit the adapter 1420 in the sink 1100c. For example, the portable fan 1000 can include a magnetic member 1500 connected to the housing assembly 1100 and arranged corresponding to the bottom of the sink 1100c, and the adapter 1420 has a matching member 1421 for magnetically matching with the magnetic member 1500 to attract the adapter 1420 to the bottom of the sink 1100c. Further, one of the surfaces of the adapter 1420 in the thickness direction can be attached to the bottom of the sink 1100c, the surface has a relatively large area, and the depth of the sink 1100c does not have to be too large to avoid too much impact on the overall appearance of the housing assembly 1100.

[0083] One of the magnetic member 1500 and the matching member 1421 is a magnet, and the other is a magnet or a ferromagnetic metal member such as iron, cobalt, nickel and their alloys. By using the magnetic matching of the magnetic member 1500 and the matching member 1421, the adapter 1420 after being bent can be reliably limited in the sink 1100c, avoiding the adapter 1420 to be drooping outside the housing assembly 1100 and adversely affecting the normal use. Of course, it can be understood that it is easier to realize that the adapter 1420 is provided with a ferromagnetic metal member and the housing assembly 1100 is provided with a magnet, for example, the outer periphery of the adapter 1420 is covered with a ferromagnetic metal member.

[0084] Of course, there are more than one way to limit the adapter 1420 in the sink 1100c, for example, the sidewall of the sink 1100c can have a clamping part for directly clamping the adapter 1420 in the sink 1100c. In other words, in this embodiment, the sidewall of the sink 1100c or the two sides of the adapter 1420 can be provided with a clamping structure that can be extruded and deformed, and in the process of pressing the adapter 1420 into the sink 1100c, the clamping structure is deformed so that the adapter 1420 is clamped into the sink 1100c. This way can also realize that the adapter 1420 is reliably limited in the sink 1100c, and when needed, the adapter 1420 can be easily taken out of the sink 1100c, and the wire body 1410 can be pulled out of the housing assembly 1100, and the structure and function of the sink 1100c can refer to the first embodiment, which will not be described here.

[0085] The technical features of the above-described embodiments can be combined in any manner. In order to make the description simple, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present disclosure.

[0086] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
