In particular, the term "a" may refer to "one" in one embodiment and "more than one" in another embodiment. Therefore, the above terms should not be construed as limiting the actual number of elements of the present invention.

[0037] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0038] refer to Figure 1 This utility model discloses a portable fan 10. The portable fan 10 is a small and lightweight air-dissipating device that provides users with immediate and targeted cooling in mobile or outdoor scenarios. Portable fans 10 include, but are not limited to, handheld fans, desktop fans, waist-mounted fans, and neck-mounted fans. To improve ease of use, these portable fans 10 are typically equipped with a rechargeable battery, such as a lithium battery, and with the development of battery technology, the battery life of these portable fans 10 is continuously improving. This application uses a waist-mounted fan, which is equipped with a battery, as an example for description, but the portable fan 10 of this application is not limited to this type of battery-equipped product. In some embodiments, the portable fan 10 may operate without a battery, powered by an external power source, an external AC power adapter, or directly by AC power.

[0039] Also refer to Figure 1 and Figure 2The portable fan 10 may include a mounting housing 20, a battery 30, a hanging member 40, and an air outlet assembly 50. The air outlet assembly 50 is disposed within the mounting housing 20. The battery 30 is disposed within the mounting housing 20 and is used to power the air outlet assembly 50. The hanging member 40 is disposed outside the mounting housing 20 and can be opened and closed relative to the mounting housing 20, allowing the portable fan 10 to be hung on the user's collar, trouser cuff, or belt. In some embodiments, the portable fan 10 includes a circuit board 60 and a retractable cable module 70 disposed within the mounting housing 20. The air outlet assembly 50 is electrically connected to the circuit board 60, and the circuit board 60 is electrically connected to the battery 30. The circuit board 60 may integrate the control circuitry of the air outlet assembly 50 and may also include functional auxiliary components such as a trigger switch (not shown) for turning the portable fan 10 on and off. The retractable cable module 70 includes a cable 71 that can extend and retract relative to the mounting housing 20. The cable 71 is electrically connected to the circuit board 60 and can be stored within the mounting housing 20. The cable 71 can also be pulled out of the mounting housing 20 to connect to external electronic devices. It is understandable that the suspension component 40 can be omitted in products such as handheld fans and neck fans.

[0040] In some embodiments, the cable 71 is wound and housed within the mounting housing 20 using structures such as a torsion spring (not shown) and a turntable (not shown). The turntable winds the cable 71 and provides a rotatable connection to the mounting housing 20, while the torsion spring retracts the cable 71 after it extends out of the housing 20. An auxiliary circuit board (not shown) is provided inside the mounting housing 20. The auxiliary circuit board has a conductive ring, and the turntable has conductive contacts. These conductive contacts are electrically connected to the cable 71, and the auxiliary circuit board is electrically connected to the circuit board 60. The conductive contact between the conductive contacts and the conductive ring ensures that the cable 71 remains electrically connected to the circuit board 60 during extension and retraction. This allows the cable 71 to be connected to an external electronic device to supply power or to charge the battery 30. For example, the external electronic device could be a mobile terminal such as a mobile phone or tablet. By connecting the cable 71 to the charging port of the mobile terminal, the battery 30 can charge the mobile terminal. Users of this portable fan 10 no longer need to carry a separate power bank to charge such mobile terminals, thus improving convenience. For example, the external device can be a small fan or display screen without its own power supply. It can be connected to such electronic devices via cable 71, or the battery 30 of the portable fan 10 can power the electronic device. Alternatively, the external electronic device can be a power bank or power adapter, and the cable can be connected to such electronic devices to charge the battery 30 inside the portable fan 10, thus avoiding the inconvenience of an additional charging cable. Charging the battery 30 of the portable fan 10 via an external electronic device falls under the field of reverse charging technology, and there are already relatively mature technical solutions, which will not be elaborated upon in this application.

[0041] refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The air outlet assembly 50 includes a housing 51, a fan 52, and an air guide 53. The housing 51 has an air inlet 511. The fan 52 is disposed inside the housing 51, and the air inlet 511 connects to the fan 52. The battery 30 supplies power to the fan 52 of the air outlet assembly 50, and the fan 52 is electrically connected to the circuit board 60. The air guide 53 is movably disposed in the housing 51 and has an air outlet 531, which connects to the fan 52. When the air outlet assembly 50 is mounted on the mounting housing 20 of the portable fan 10, the air guide 53 protrudes from the mounting housing 20 and can move relative to the housing 51 to change the orientation of the air outlet 531. When a user uses the portable fan 10 equipped with the aforementioned air outlet assembly 50, the air guide 53 of the air outlet assembly 50 can be adjusted according to actual needs, thereby adjusting the airflow direction of the portable fan 10 and improving the flexibility of the portable fan 10.

[0042] refer to Figure 5 and Figure 6 In some embodiments, the housing 51 includes a base shell 512 and a constraint member 513 connected to one end of the base shell 512. The base shell 512 has an air inlet 511, and a fan 52 is disposed on the base shell 512 and located between the air inlet 511 and the air outlet 531. The air guide member 53 is movably confined within the constraint member 513. Specifically, as shown... Figure 5 As shown, the housing 51 can be approximately cylindrical in shape, with a constraint member 513 disposed at one end of the base housing 512 and an air inlet 511 disposed at the other end of the base housing 512. The base housing 512 has a receiving hole 5121 communicating with the air inlet 511, extending from one end of the air inlet 511 to the opposite end of the base housing 512. The base housing 512 may also include a plurality of first connecting portions 5122 spaced apart circumferentially on the base housing 512. The first connecting portions 5122 are used for assembly with corresponding parts of the mounting shell 20 of the portable fan 10, for example, by using threaded fasteners such as screws to achieve a detachable connection between the air outlet assembly 50 and the mounting shell 20.

[0043] refer to Figure 5 , Figure 6 and Figure 7In some embodiments, the air guide 53 has an air inlet 533 opposite to the air outlet 532. The diameter of the air outlet 532 is smaller than the diameter of the air inlet 533, and the air inlet 533 is closer to the fan 52 than the air outlet 532. The air outlet 532 and the air inlet 533 of the air guide 53 are interconnected to form an air supply channel, and the cross-section of the air supply channel gradually increases from the air outlet 532 to the air inlet 533 along the axial direction of the air guide 53. That is, the air guide 53 adopts a tapered flow channel design. This structure reduces the flow cross-sectional area of ​​the air supply channel, so that the airflow velocity at the air outlet 532 can be higher than the airflow velocity at the air inlet 533 during the air supply process. When the fan 52 is running, air enters from the air inlet 533, is accelerated and pressurized by the tapered flow channel of the air guide 53, and is blown out from the air outlet 532, thereby enhancing the airflow of the portable fan 10.

[0044] refer to Figure 5 , Figure 6 and Figure 7 In some embodiments, the outer surface of the air guide 53 between the air outlet 532 and the air inlet 533 is part of a sphere, and the inner surface shape of the constraint member 513 matches that of the air guide 53. Figure 6 As shown, the constraint member 513 is approximately a hollow ball table, and the air guide member 53 is also approximately a hollow ball table. The air guide member 53 and the constraint member 513 cooperate to form a ball joint, thereby allowing the orientation of the air outlet 531 of the air guide member 53 to be flexibly adjusted.

[0045] Specifically, the constraint member 513 includes a connector 5131 and a limiting member 5132. In the axial direction of the fan 52, the connector 5131 connects the base shell 512 and the limiting member 5132. The connector 5131 and the limiting member 5132 enclose a limiting cavity 5133. The air guide member 53 is movably disposed within the limiting cavity 5133 and protrudes from the end of the limiting member 5132 away from the fan 52. For example, as shown... Figure 5As shown, the connector 5131 may include a first connector 51311, a receiving portion 51312 integrally formed with the first connector 51311, and a plurality of second connector portions 51313 spaced apart and protruding on the outer surface of the connector 5131. The limiting member 5132 includes a third connector portion 51321 that mates with the second connector portions 51313 of the connector 5131. After the second connector portions 51313 of the connector 5131 and the third connector portions 51321 of the limiting member 5132 are matched, they can be connected by threaded fasteners such as screws. In some embodiments, the first connector 51311 has a first mounting hole 5131a, and the base shell 512 includes a second connector 5123 that matches the first connector 51311 of the connector 5131, and a second mounting hole 5124 disposed on the second connector 5123 and matching the first mounting hole 5131a of the first connector 51311. After the connector 5131 is matched with the second mounting hole 5124 of the base shell 512 through the first mounting hole 5131a of the first connector 51311, it can be connected by threaded fasteners.

[0046] Furthermore, the limiting member 5132 has a first opening 51322 and a second opening 51323. The diameter of the first opening 51322 is smaller than the diameter of the second opening 51323. The second opening 51323 is closer to the fan 52 than the first opening 51322. The diameter of the second opening 51323 is larger than the outer diameter of the air inlet 533 of the air guide member 53. The diameter of the first opening 51322 is larger than the outer diameter of the air outlet 532 of the air guide member 53 and smaller than the outer diameter of the air inlet 533 of the air guide member 53. The air guide member 53 protrudes from the first opening 51322. The inner surface of the limiting member 5132 between the first opening 51322 and the second opening 51323 is part of a sphere.

[0047] In some embodiments, the connector 5131 has a fifth opening 51314 disposed in the receiving portion 51312 and a sixth opening 51315 disposed in the first connecting seat 51311. The diameter of the fifth opening 51314 is larger than the diameter of the sixth opening 51315, and the sixth opening 51315 is closer to the fan 52 than the fifth opening 51314. The diameter of the fifth opening 51314 is larger than the outer diameter of the air inlet 533 of the air guide 53, and the diameter of the sixth opening 51315 is smaller than the outer diameter of the air inlet 533 of the air guide 53. The diameter of the fifth opening 51314 may be comparable to the diameter of the second opening 51323 of the limiting member 5132. The inner surface of the receiving portion 51312 of the connector 5131 between the fifth opening 51314 and the sixth opening 51315 of the first connecting seat 51311 is part of a spherical surface. When the air guide 53 is disposed within the limiting cavity 5133 formed by the receiving portion 51312 of the limiting member 5132 and the connecting member 5131, such as Figure 6As shown, the limiting member 5132 and the receiving portion 51312 of the connecting member 5131 form a limiting cavity 5133 that matches the air guide member 53, which is used to accommodate the air guide member 53 and limit the rotation range of the air guide member 53 in the limiting cavity 5133 through the first connecting seat 51311.

[0048] Furthermore, refer to Figure 5 , Figure 6 and Figure 9 The air outlet assembly 50 includes a fixing member 54 disposed at the end of the fan 52 away from the air inlet 511, and an air guide member 53 hinged to the fixing member 54. The circumferential direction of the fixing member 54 forms an air duct with the inner side of the connecting member 5131, the air duct connecting the fan 52 and the limiting cavity 5133, the inner diameter of the air duct being smaller than the diameter of the second opening 51323. In some embodiments, the fixing member 54 has a hinged ball head 541 extending into the limiting cavity 5133, and the air guide member 53 is hinged to the hinged ball head 541. Specifically, as shown... Figure 9 As shown, the fixing member 54 includes a support base 542 disposed opposite to the hinge ball head 541, and a support rod 543 connecting the hinge ball head 541 and the support base 542. The side of the support base 542 away from the hinge ball head 541 may include two or more pins 5421, which, when combined... Figure 10 The fan 52 may include a pin groove 521 that mates with the pin 5421 of the support base 542. The pin 5421 of the support base 542 and the pin groove 521 of the fan 52 are matched and connected to fix the fixing member 54 to the side of the fan 52 near the air guide member 53. The hinged ball head 541 on the other side of the fixing member 54 is hinged to the air guide member 53 and provides support for the air guide member 53, making the rotation of the air guide member 53 smoother. The hinge between the air guide member 53 and the hinged ball head 541 can have appropriate damping to achieve immediate positioning of the air guide member 53 after rotation, preventing the air guide member 53 from easily swaying relative to the restraint member 513 during fan operation.

[0049] Continue to refer to Figure 5 , Figure 6 and Figure 7 In some embodiments, the air guide 53 includes an integrally formed outer cover 534, connecting strips 535, and a hinge portion 536. The outer cover 534 has an air outlet 532 and an air inlet 533. The hinge portion 536 is spaced apart from the outer cover 534. Multiple connecting strips 535 are provided, each connecting strip 535 connecting between the outer cover 534 and the hinge portion 536. The multiple connecting strips 535 are evenly arranged circumferentially on the hinge portion 536. The hinge portion 536 has a groove 5361 on the side facing the fixing member 54 for hinged engagement with a hinge ball head 541. The hinge portion 536 covers at least a portion of the hinge ball head 541 through the groove 5361 and is hinged to the hinge ball head 541. For example, as... Figure 7As shown, three connecting strips 535 and a hinge portion 536 are disposed on the side of the outer cover 534 near the fixing member 54. One end of the connecting strip 535 is fixed to the inner wall of the outer cover 534, and the other end is fixedly connected to the hinge portion 536. The included angle between adjacent connecting strips 535 can be 120 degrees. The hinge portion 536 can be located at the center of the air guide member 53 and can be disposed on the extended axis of the fan 52.

[0050] refer to Figure 5 , Figure 6 and Figure 10 In some embodiments, the fan 52 may include a drive component 522, a fan body 523 linked to the output end of the drive component 522, and a fan housing 524 for accommodating the drive component 522 and the fan body 522. The fan housing 524 includes a mounting base 5242 and a plurality of fixing strips 5241. The plurality of fixing strips 5241 are distributed circumferentially at intervals along the mounting base 5242. One end of the fixing strip 5241 is fixedly connected to the fan housing 524, and the other end is fixedly connected to the mounting base 5242, so that a ventilation channel is formed between the mounting base 5242 and the fan housing 524. A pin groove 521 that cooperates with the pin 5421 of the fixing component 54 is provided on the side of the mounting base 5242 near the fixing component 54. The drive component 522 is disposed inside the fan housing 524 and located on the side of the mounting base 5242 opposite to the fixing component 54. The drive unit 522 can be a DC brushless motor. The output of the motor is linked to the fan body 522, driving the fan body 522 to rotate and guide the air to the air outlet 531 of the air guide 53. The battery 30 of the portable fan 10 can power the drive unit 522 of the fan 52.

[0051] Combination Figure 6 In some embodiments, the base shell 512 includes a limiting protrusion 5125 protruding from its inner surface, and the air outlet assembly 50 includes a buffer member 55 disposed between the inner surface of the base shell 512 and the fan housing 524. When the fan housing 524 is assembled into the receiving hole 5121 in the base shell 512, the buffer member 55 is first sleeved on the fan housing 524, and then the fan housing 524 and the buffer member 55 are placed into the receiving hole 5121 of the base shell 512, with one end of the fan housing 524 abutting against the limiting protrusion 5125 of the base shell 512. At the opposite end of the fan housing 524, the diameter of the sixth opening 51315 of the first connecting seat 51311 of the connector 5131 can be smaller than the outer diameter of the fan housing 524, so that the first connecting seat 51311 of the connector 5131 abuts against the fan housing 524, thereby reliably confining the fan 52 in the receiving hole 5121 of the base shell 512. The buffer 55 can provide cushioning and shock absorption. It can be made of silicone, rubber or foam. It is used to cushion and absorb shock of the fan 52 and maintain a stable connection between the mounting shell 20 and the base shell 512 of the fan 52.
