[0032] 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.

[0033] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] refer to Figure 1 , Figure 2 and Figure 3This application discloses a liftable fan 10, including a fan assembly 100, a power module 200, and a telescopic cable module 300. The fan assembly 100 includes at least two support members 110 that can move relatively vertically, and an air outlet assembly 120 connected to one of the support members 110. The air outlet assembly 120 may include a fan, such as an axial fan or a centrifugal fan, which can guide airflow during operation to dissipate heat for the user. In some embodiments, the fan may also employ an air compressor, such as a turbocharger, to achieve a bladeless design in the appearance of the liftable fan 10, i.e., to achieve a bladeless fan effect, making the appearance of the liftable fan 10 more concise.

[0036] The power module 200 is connected to the fan assembly 100 and is used to power the air outlet assembly 120. The power module 200 of the lift-up fan 10 generally includes a rechargeable battery such as a lithium battery, and with the advancement of battery technology, the capacity of batteries is on the rise, thus the battery life of the lift-up fan 10 is steadily improving.

[0037] After at least two support members 110 move up and down relative to each other, the height of the air outlet assembly 120 relative to a supporting surface such as a table or the ground can be adjusted, thereby adjusting the height of the air outlet assembly 120 and improving ease of use. For example, in a home environment, by adjusting the height of the air outlet assembly 120 relative to a table or the ground using the support members 110, the user can direct the air outlet assembly 120 towards different parts of the body. In outdoor environments such as camping, the user can also adjust the height of the air outlet assembly 120 relative to the ground or other supporting surfaces using the support members 110, thereby improving ease of use. In some embodiments, the air outlet assembly 120 can also be hinged to the support members 110, allowing for pitch and rotation relative to the support members 110 to adjust the pitch angle of the air outlet assembly 120, further enabling flexible adjustment of the air outlet direction and improving ease of use.

[0038] A retractable cable module 300 is disposed in the fan assembly 100 and includes a cable 310. The cable 310 is retractable relative to the power module 200 to be stored in the fan assembly 100 or pulled out of the fan assembly 100, and connected to an external electronic device to power the external electronic device through the power module 200. In some embodiments, the cable 310 can be coiled and stored inside the fan assembly 100 to achieve a hidden cable 310 effect, keeping the lift-up fan 10 in a relatively simple appearance and avoiding inconvenience to the user during daily use, such as preventing the cable 310 from getting tangled with other items during transportation or when not in use. When the user needs to power an external electronic device such as a mobile phone, the cable 310 of the retractable cable module 300 can be pulled out from the fan assembly 100 and connected to the external electronic device, and the power module 200 of the lift-up fan 10 can power these external electronic devices, such as charging a mobile phone, improving the convenience of use.

[0039] Also refer to Figure 4 In some embodiments, the cable 310 may include a cable body 311, a connector 313, and a digital display 315. The digital display 315 is connected between the free end of the cable body 311 and the connector 313, which is used to connect to an external electronic device. The connector 3131 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 315 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 310, improving ease of use. Of course, the digital display 315 is not mandatory; for example, in… Figure 1 , Figure 2 In the embodiment shown, the cable 310 does not have a digital display unit 315.

[0040] Continue to refer to Figure 2 and Figure 3 The fan assembly 100 includes a base 130, a support member 110 disposed between the base 130 and the air outlet assembly 120, so as to adjust the distance between the air outlet assembly 120 and the base 130 via the support member 110. The power module 200 and the telescopic cable module 300 are respectively disposed on the base 130. The base 130 can have a relatively large width and mass to lower the center of gravity of the entire lift-up fan 10 and improve the support stability of the lift-up fan 10. Of course, in other embodiments, the power module 200 can be disposed on the air outlet assembly 120, the telescopic cable module 300 can also be disposed on the air outlet assembly 120, and the base 130 is only used to improve the support stability of the lift-up fan 10.

[0041] refer to Figure 2 and Figure 3In some embodiments, the base 130 is a hollow cylindrical shape, having a cavity 130a and an opening 130b communicating with the cavity 130a. The power module 200 is disposed within the cavity 130a, and the cable 311 passes through the opening 130b. With the cable 310 retracted into the base 130, the mating portion 313 passes through the opening 130b and at least partially protrudes from the base 130. In other words, with the cable 310 retracted into the fan assembly 100, the mating portion 313 can partially protrude from the base 130, allowing the user to easily grasp the mating portion 313 with their fingers and pull the cable 310 out of the base 130.

[0042] Of course, in other embodiments, with the cable 310 retracted in the base 130, the mating part 313 can also be completely housed within the base 130, meaning the mating part 313 does not protrude from the surface of the base 130, thereby preventing damage or scratches to the interface caused by accidental collisions. In this embodiment, the base 130 can be equipped with a pop-up structure, such as a push-push structure, to position the mating part 313 in the retracted state and allow it to automatically pop out of the base 130 when pressed, improving ease of use.

[0043] Furthermore, the base 130 may include a seat body 131 and at least three legs 133 movably connected to the seat body 131 and evenly spaced circumferentially from the seat body 131. The legs 133 are capable of opening or closing relative to the seat body 131. Figure 2 Taking the illustrated embodiment as an example, the end of the base 131 furthest from the air outlet assembly 120 is provided with three support legs 133. The three support legs 133 are evenly spaced around the circumference of the base 130, that is, the central angle between adjacent support legs 133 is approximately 120 degrees. The base 130 can be provided with mounting grooves 130c spaced apart from the cavity 130a. The support legs 133 are rotatably disposed in the mounting grooves 130c, thereby realizing the opening or closing of the support legs relative to the base 131.

[0044] When the fan is open, the ends of the three legs 133 furthest from the air outlet assembly 120 are basically on a plane, and the area of ​​the triangle formed by the line connecting the ends of the three legs 133 is larger than the vertical projection area of ​​the base 130, thereby increasing the support width of the lifting fan 10 and reliably supporting the entire lifting fan 10 on a table or ground surface. The ends of the base 130 furthest from the air outlet assembly 120 are spaced apart from the support surface to prevent the base 130 from getting damp or dirty. When the fan is closed, the legs 133 can rotate to a state that is basically parallel to the axis of the base 130, or in other words, basically parallel to the lifting direction of the support member 110, so as to reduce the size occupied by the lifting fan 10 in the width direction, improve the compactness of the structure, and facilitate transportation or storage.

[0045] Of course, in some embodiments, a folding structure similar to a camera tripod can be adopted, so that the legs 133 in the close-up state can be folded towards the direction of the air outlet assembly 120 and close to the outer wall of the base 130, further reducing the length of the lifting fan 10, improving the compactness of the structure and making it easier to transport or store.

[0046] The support member 110 is a hollow tubular structure, and multiple support members 110 are nested in stages, for example, three support members 110 are nested in stages to form a three-stage telescopic structure. The interior of the support member 110 is used for wiring to achieve electrical connection between the air outlet assembly 120 and the power module 200. In other words, in this embodiment, the liftable fan 10 may include multiple tubular support members 110, which are nested in stages, that is, the tubular support member 110 with a smaller inner diameter is inserted into the tubular support member 110 with a larger inner diameter. This allows the height of the air outlet assembly 120 and the support surface such as the table or ground to be changed when two adjacent tubular support members 110 move relative to each other, thereby achieving multi-stage telescopic movement. The internal wiring of the support member 110 can prevent the cable 310 of the air outlet assembly 120 from being exposed outside the liftable fan 10 and accidentally damaged, thereby ensuring the reliability of the cable 310 and ensuring the service life of the liftable fan 10. When the multi-stage support member 110 is in the extended state, the adjacent two stages of support members 110 can be positioned instantly by using damping, or by engaging the elastic pin with the hole, or by tightening with bolts. These details will not be elaborated here.

[0047] In some embodiments, the support member 110 connected to the air outlet assembly 120 can be detachably connected to the air outlet assembly 120 by means of a threaded connection, so as to facilitate the removal of the air outlet assembly 120 from the support member 110 and further improve the convenience of handling or storage.

[0048] Furthermore, in some embodiments, the base 130 is provided with a countersunk hole 130d, and at least one support member 110 is telescopically disposed within the countersunk hole 130d. Specifically, in embodiments where the support member 110 is a hollow tube, the outermost support member 110 or the support member 110 with the largest inner diameter is telescopically disposed within the countersunk hole 130d and can telescopically move within the countersunk hole 130d to be at least partially housed within the countersunk hole 130d, or to extend beyond the base 130 from within the countersunk hole 130d. With this structure of the countersunk hole 130d, when the distance between the air outlet assembly 120 and the base 130 is closest, the support member 110 can be housed as much as possible within the countersunk hole 130d, thereby reducing the length of the lifting fan 10, improving the compactness of the structure, and facilitating transportation or storage.

[0049] Continue to refer to Figure 2 and Figure 3The lift-up fan 10 may include a circuit board 400 disposed within the fan assembly 100. The circuit board 400 may integrate the control circuitry and power management unit of the lift-up fan 10. The cable 310, the fan of the air outlet assembly 120, and the power module 200 are electrically connected to the circuit board 400. The fan's start / stop button, speed adjustment knob, and other components can be correspondingly configured with the control circuitry on the circuit board 400 to achieve their respective functions; these details will not be elaborated further. Simultaneously, in conjunction with... Figure 5 and Figure 6 The retractable cable module 300 may include a housing 320 disposed within the fan assembly 100. The housing 320 is fixed in position relative to the power module 200, and the cable 310 is retractably disposed within the housing 320. The housing 320 may be fixedly connected to the circuit board 400 or to the fan assembly 100, such as the base 130, thereby achieving relative fixation between the housing 320 and the circuit board 400. The retractable cable module 300, including the housing 320, can be manufactured as an independent module and assembled into the fan assembly 100, such as the base 130, thereby improving assembly efficiency and ensuring the reliability of the retractable cable module 300.

[0050] Specifically, in combination Figure 5 The telescopic cable module 300 may include a circuit board 330, a torsion spring 340, and a turntable 350 disposed within a housing 320. The circuit board 330 is fixedly positioned relative to the housing 320, for example, it is fixedly connected to the housing 320 or to the base 130 of the fan assembly 100. The circuit board 330 is electrically connected to the circuit board 400, for example, through wire bonding. The torsion spring 340 may be helical and has a first free end 341 and a second free end 343. The first free end 341 of the torsion spring 340 is connected to the turntable 350, and the second free end 343 is fixedly positioned relative to the circuit board 330, for example, it is fixedly connected to the housing 320 or the circuit board 330. The turntable 350 is rotatably connected to the housing 320, for example, one of the turntable 350 and the housing 320 has a rotating shaft, and the other has a shaft hole, thereby realizing the rotatable connection between the turntable 350 and the housing 320. Cable 310 is wound around the outer periphery of torsion spring 340. One of the circuit board 330 and turntable 350 has a contact pin (not shown), and the other has a ring conductor (not shown). The contact pin makes contact with the ring conductor, and cable 310 is electrically connected to the contact pin or ring conductor on turntable 350, thereby achieving an electrical connection between cable 310 and circuit board 330. For example, circuit board 330 has a contact pin, turntable 350 has a ring conductor, and cable 310 is electrically connected to the ring conductor; or circuit board 330 has a ring conductor, turntable 350 has a contact pin, and cable 310 is electrically connected to the contact pin, achieving an electrical connection between cable 310 and circuit board 330. Of course, cable 310 can also be directly electrically connected to circuit board 330 through wire bonding or other methods.

[0051] Cable 310 can be held in place by turntable 350. When the user pulls cable 310, it causes turntable 350 to rotate relative to housing 320 in one direction, such as clockwise, to gradually extend beyond housing 320. During this process, the contact pin remains in contact with the annular conductor, thereby ensuring the electrical connection between cable 310 and circuit board 400. During this process, torsion spring 340 accumulates elastic potential energy, causing turntable 350 to tend to rotate counterclockwise. When the user no longer needs to power external electronic devices through the power module 200 of the lifting fan 10, torsion spring 340 can release elastic potential energy, causing cable 310 extending beyond housing 320 to gradually retract into housing 320.

[0052] Simultaneously combined Figure 6 In some embodiments, the telescopic cable module 300 includes a locking block 360 rotatably connected to the housing 320. The turntable 350 has a locking position 351 and an unlocking position 353. During the process of the cable 310 being pulled out of the housing 320, when the cable 310 drives the turntable 350 to rotate to the locking position 351 corresponding to the locking block 360, the locking block 360 restricts the rotation of the turntable 350. When the cable 310 continues to be pulled out of the housing 320 and drives the turntable 350 to rotate, the locking block 360 rotates relative to the housing 320 and moves to the unlocking position 353, so that the cable 310 can be gradually wound into the housing 320. Figure 6 The turntable 350 is shown to have corresponding limiting grooves 350a and guide grooves 350b. The groove wall of the limiting groove 350a can be used as the stop position 351, and the connection between the groove wall of the guide groove 350b and the groove wall of the limiting groove 350a is the unlock position 353.

[0053] The sidewall of the guide groove 350b can guide and limit the movement of the end of the locking block 360, so that the end of the locking block 360 continues to move along the guide groove 350b during the pulling process of the cable 310. When the user stops pulling the cable 310 out, the torsion spring 340 drives the turntable 350 to rotate in the opposite direction (e.g., clockwise). The end of the locking block 360 is guided by the sidewall of the guide groove 350b into the limiting groove 350a, thereby stopping the cable 310. When the user continues to pull the cable 310 out, the turntable 350 continues to rotate in the original direction (e.g., counterclockwise). The end of the locking block 360 exits the limiting groove 350a and enters the guide groove 350b, and the cable 310 can continue to be pulled out.

[0054] When the user pulls the cable 310 out of the housing 320 and drives the turntable 350 to rotate, the end of the locking block 360 moves along the guide groove 350b to the locking position 351. At this time, if the user stops pulling the cable 310, under the action of the torsion spring 340, the end of the locking block 360 abuts against the groove wall of the limiting groove 350a, and the turntable 350 stops rotating, thus achieving the locking effect of the cable 310. When the user continues to pull the cable 310 out of the housing 320 and drives the turntable 350 to rotate, the locking block 360 rotates relative to the housing 320 and retracts to the guide groove 350b. It can switch to the guide groove 350b and continue to move along the guide groove 350b, that is, reach the unlocking position 353. The turntable 350 can continue to rotate, causing the cable 310 to continuously extend out of the housing 320, or the cable 310 can gradually be wound back into the housing 320. The combination of the above-mentioned card block 360 and turntable 350 can achieve the stopping and automatic winding effect of cable 310, improving the convenience of use. Moreover, the turntable 350 can be set with more than two stopping positions 351 and unlocking positions 353, and the stopping positions 351 and unlocking positions 353 can be matched one-to-one.

[0055] Of course, in other embodiments, other structures can be used to replace the locking effect of the locking block 360 on the cable 310. For example, the lifting fan 10 may include a limiting member (not shown) that is movably fitted to the base 130. The limiting member has a first position and a second position. In the first position, the cable 310 can be pulled out or retracted into the fan assembly 100. In the second position, the limiting member abuts against the cable 310 and restricts the movement of the cable 310 relative to the fan assembly 100.

[0056] For example, the limiting member slides with the fan assembly 100, such as the base 131, and the sliding of the limiting member with the fan assembly 100 has appropriate damping to prevent the limiting member from easily retracting. When the user needs to stop the cable 310 while pulling it out, the limiting member is pushed relative to the fan assembly 100 to the position that abuts the cable 310, i.e., the second position, which can stop the cable 310 in the fan assembly 100; when the user needs to retract the cable 310 into the fan assembly 100, the limiting member is pushed in the opposite direction to the first position. After the limiting member no longer abuts the cable 310, the cable 310 can be retracted into the cover 320 under the action of the torsion spring 340 and the turntable 350.

[0057] For example, the limiting member rotates with the fan assembly 100, such as the base 131. The limiting member may have an eccentric wheel structure and appropriate rotational damping to prevent the limiting member from easily retracting. When the user needs to stop the cable 310 while pulling it out, the limiting member is rotated so that the eccentric wheel of the limiting member presses against the cable 310, i.e., reaches the second position, thus stopping the cable 310 in the fan assembly 100. When the user needs to retract the cable 310 into the fan assembly 100, 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 310, the cable 310 can be retracted into the cover 320 under the action of the torsion spring 340 and the turntable 350.

[0058] Both of the above-described limiting components can stop the cable 310, and when combined with the torsion spring 340, they can achieve an automatic winding effect, improving ease of use. In other embodiments, the limiting components can also adopt other structural forms to achieve the same stopping effect on the cable 310.

[0059] It is understandable that the housing 320 of the telescopic cable module 300 is not essential and can be omitted to simplify the structure of the lift-up fan 10 and improve its compactness. For example, the telescopic cable module 300 includes a torsion spring 340 and a turntable 350. The first free end 341 of the torsion spring 340 is connected to the turntable 350, and the second free end 343 of the torsion spring 340 is fixed relative to the position of the circuit board 400. The cable 310 is wound around the outer periphery of the torsion spring 340 and is directly electrically connected to the circuit board 400, for example, by soldering or combining lead wire soldering, or by using a contact pin and a ring conductor to achieve an electrical connection between the cable 310 and the circuit board 400. The cable 310 can be held in place by the turntable 350, and when the user pulls the cable 310, it causes the turntable 350 to rotate relative to the circuit board 400 in one direction, such as clockwise, to gradually extend out of the fan assembly 100. During this process, the torsion spring 340 accumulates elastic potential energy, causing the turntable 350 to tend to rotate counterclockwise. When the user no longer needs to power external electronic devices through the lifting fan 10, the torsion spring 340 releases its elastic potential energy, causing the cable 310 extending outside the fan assembly 100 to gradually retract into the fan assembly 100.

[0060] In this embodiment, the telescopic cable module 300 may also include a locking block 360, which is rotatably connected to the circuit board 400 or the base 130 of the fan assembly 100. The turntable 350 has a locking position 351 and an unlocking position 353. During the process of the cable 310 being pulled out of the fan assembly 100, when the cable 310 drives the turntable 350 to rotate to the locking position 351 corresponding to the locking block 360, the locking block 360 restricts the rotation of the turntable 350. When the cable 310 continues to be pulled out of the fan assembly 100 and drives the turntable 350 to rotate, the locking block 360 moves relative to the turntable 350 to the unlocking position 353, so that the cable 310 is gradually wound into the fan assembly 100. The locking principle and structure of the locking block 360 for the cable 310, as well as the unlocking principle and structure, can be referred to the foregoing content and will not be repeated here. The combination of the above-mentioned locking block 360 and turntable 350 can stop the cable 310, and combined with the torsion spring 340, it can achieve an automatic winding effect, improving the convenience of use.

[0061] Of course, in this embodiment, the lifting fan 10 may also include a limiting member that is movably fitted to the fan assembly 100. The limiting member has a first position and a second position. In the first position, the cable 310 can be pulled out or retracted into the fan assembly 100; in the second position, the limiting member abuts against the cable 310 and restricts the movement of the cable 310 relative to the fan assembly 100. The principle and structure of the limiting member in stopping the cable 310, as well as the principle and structure of unlocking the cable 310, can be referred to the foregoing content and will not be repeated here. The structure of the limiting member can achieve the stopping of the cable 310, and combined with the torsion spring 340, it can achieve an automatic winding effect, improving the convenience of use. In other embodiments, the limiting member may also adopt other structural forms to achieve the stopping effect of the cable 310.

[0062] The above-mentioned height-adjustable fan 10 includes a fan assembly 100, a power supply module 200, and a retractable cable module 300. The fan assembly 100 includes at least two relatively movable support members 110 and an air outlet assembly 120 connected to one of the support members 110. The power supply module 200 is connected to the fan assembly 100 and is used to power the air outlet assembly 120. The retractable cable module 300 is located in the fan assembly 100 and includes a cable 310. The cable 310 can be extended or retracted relative to the power supply module 200 to be stored in the fan assembly 100 or pulled out of the fan assembly 100, and is connected to an external electronic device to power the external electronic device through the power supply module 200. After the at least two support members 110 are relatively movable, the height of the air outlet assembly 120 relative to the desktop or the ground can be adjusted, improving the convenience of use. When a user uses the lift-up fan 10 and needs to charge it, the cable 310 of the retractable cable module 300 can be pulled out from the fan assembly 100 of the lift-up fan 10 and connected to an external electronic device such as a mobile phone. The power module 200 of the lift-up fan 10 then powers and charges the external electronic device, eliminating the need for a separate power bank and charging cable, thus improving convenience. Even when the external electronic device does not have a rechargeable battery, the user can still power it using the power module 200 of the lift-up fan 10. When the user no longer needs to power the external electronic device through the lift-up fan 10, the cable 310 of the retractable cable module 300 can be stored inside the fan assembly 100, allowing the lift-up fan 10 to maintain a relatively simple appearance, making it easy for users to carry and use, and further enhancing convenience.
