[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0032] Please see Figure 1-15 A foldable fan according to an embodiment of the present invention includes a base 100 and a fan bracket 200. The base 100 is connected to the fan bracket 200 through a rotatable structure, and the fan bracket 200 can rotate relative to the base 100.

[0033] The rotatable structure includes a fixed part 400 and a rotating part 300. The fixed part 400 is connected to the base 100, and the rotating part 300 is connected to the fan bracket 200. The rotating part 300 can rotate relative to the fixed part 400, thereby driving the fan bracket 200 to rotate relative to the base 100.

[0034] In this embodiment, by providing a rotatable structure between the seat 100 and the fan bracket 200, the fan bracket 200 can rotate relative to the seat 100 for folding, thereby saving space when storing and making it easy to carry, suitable for camping and other scenarios.

[0035] When needed, the power can be turned on directly, or the fan bracket 200 can be rotated relative to the base 100 to form a certain angle, so that the fan blades 700 in the fan bracket 200 rotate and blow air under the drive of the rotating motor.

[0036] The rotatable structure includes a fixed part 400 and a rotating part 300, which are rotatably connected. The fixed part 400 is disposed on the base 100, and the rotating part 300 is disposed on the fan bracket 200. The fan bracket 200 can rotate relative to the fixed part 400 through the rotating part 300, and thus rotate relative to the base 100.

[0037] Among them, the rotatable connection can be a shaft-hole connection.

[0038] In a preferred embodiment, the rotating part 300 and the fan bracket 200 are integrally formed, which can reduce the number of assembly parts and reduce the assembly difficulty.

[0039] In one embodiment, the fan bracket 200 is provided with a fan blade 700 and a rotating motor that drives the fan blade 700 to rotate. The rotating motor is fixed to the air inlet grille 210 of the fan bracket 200. A disc 600 is provided in the middle of the air outlet grille 220 of the fan bracket 200. The disc 600 is detachably connected to the air outlet grille 220.

[0040] In this embodiment, by setting the disc 600, the disassembly and assembly of the air outlet grille 220 are made easier. At the same time, the disc 600 is set to be detachable, so that it can be removed when cleaning is required, thus avoiding some gaps that cannot be cleaned.

[0041] The disc 600 is provided with a protrusion or a recess, which allows for easy operation of the disc 600 or indirect operation of the air outlet grille 220.

[0042] The fan bracket 200 has an air outlet grille 220 on the front and an air inlet grille 210 on the rear.

[0043] The air inlet grille 210 can be detachably connected to the fan bracket 200, or it can be integrated with the fan bracket 200.

[0044] In one embodiment, the air outlet grille 220 is detachably connected to the fan bracket 200.

[0045] The detachable connection is a snap-fit ​​connection, that is, the air outlet grille 220 is connected to the fan bracket 200 through a snap-fit ​​structure.

[0046] In one embodiment, the snap-fit ​​connection can be provided with a rotating locking position on the air outlet grille 220 and a locking protrusion 212 on the fan bracket 200. The rotating locking position is an arc-shaped groove 225 extending along the edge of the air outlet grille 220. One end of the arc-shaped groove 225 is provided with a first notch 227, and a first limiting block 226 is provided in the arc-shaped groove 225.

[0047] In this embodiment, during assembly, the locking protrusion 212 is aligned with the first notch 227 and the locking protrusion 212 is inserted into the arc groove 225. The air outlet grille 220 is rotated, which drives the locking protrusion 212 to rotate until the locking protrusion 212 passes the first limiting block 226, thereby temporarily connecting the air outlet grille 220 and the fan bracket 200.

[0048] In one embodiment, a locking protrusion 610 is provided on the inner side of the disc 600, and a corresponding locking through hole 221 is provided on the air outlet grille 220. The locking through hole 221 is arc-shaped and extended, and a second notch 223 is provided on one side of the locking through hole 221, and a second limiting block 222 is provided on one side of the second notch 223.

[0049] In this embodiment, a limiting member is provided at the distal end of the locking protrusion 610. In use, the locking protrusion 610 is engaged at the second notch 223 and rotates relative to the air outlet grille 220. After applying a certain force, it can pass over the second limiting block 222 and enter the locking through hole 221. At this time, the limiting member restricts the locking protrusion 610 from axially disengaging from the locking through hole 221, while the second limiting block 222 simultaneously restricts the locking protrusion 610 from rotating out of the locking through hole 221, thereby achieving the purpose of installing the disc 600.

[0050] The above installation method can make the installation of the disc 600 more stable.

[0051] In one embodiment, the first limiting block 226 is an arc-shaped block.

[0052] In this embodiment, the arc-shaped block makes it easier to install the air vent grille 220, and the locking protrusion 610 is easier to pass over, reducing the assembly difficulty.

[0053] In one embodiment, the second limiting block 222 is an arc-shaped block.

[0054] In this embodiment, the arc-shaped block makes it less difficult to install the disc 600, and the locking protrusion 610 is easier to pass over, reducing the assembly difficulty.

[0055] In one embodiment, a clearance through hole 224 is provided below the locking through hole 221, and the locking through hole 221 and the clearance through hole 224 are connected at the second notch 223, forming a deformable locking extension between the locking through hole 221 and the clearance through hole 224.

[0056] In this embodiment, by providing a clearance through hole 224, the locking extension can undergo slight deformation, further reducing the assembly difficulty and making it easier for the locking protrusion 610 to pass over the limiting block.

[0057] In one embodiment, the rotation direction of the mounting disc 600 is the same as the rotation direction of the mounting air outlet grille 220.

[0058] In this embodiment, by making the rotation direction of the mounting disc 600 the same as the rotation direction of the mounting air outlet grille 220, when the air outlet grille 220 is installed after the mounting disc 600 is installed, applying force to the disc 600 will not cause the disc 600 to detach from the air outlet grille 220.

[0059] Specifically, the rotation direction of the mounting disc 600 is determined by the extension direction of the locking through hole 221 and the position of the second notch 223.

[0060] Specifically, the rotation direction of the installed air outlet grille 220 is determined by the extension direction of the arc groove 225 and the position of the first notch 227.

[0061] In one embodiment, the air outlet grille 220 corresponding to the disc 600 is provided with a plurality of air outlet holes, and the center of the disc 600 is hollowed out to form an air outlet, thereby increasing the number of air outlets and improving the air blowing effect.

[0062] In one embodiment, a transverse protrusion 620 is provided in the middle of the disk 600.

[0063] In one embodiment, the fixing part 400 is disposed on one side of the base 100 and forms an L-shape, the rotating part 300 is disposed on one side of the fan bracket 200, and the rotating part 300 is rotatably connected to the fixing part 400.

[0064] In this embodiment, since the fixing part 400 is located on one side of the base 100 and the rotating part 300 is located on one side of the fan bracket 200, the fan bracket 200 is positioned further forward during use, resulting in a stronger airflow.

[0065] Moreover, when storing, it will not affect the thickness of the fan bracket 200 and the base 100.

[0066] In one embodiment, a recess 110 is provided in the middle of the base 100, and the recess 110 is provided corresponding to the air inlet grille 210 on the fan bracket 200, so that the fan bracket 200 and the base 100 fit more closely when stored.

[0067] In one embodiment, a wire routing groove 211 is provided between the fan bracket 200 and the rotating part 300 on the air inlet grille 210, and a cover 800 that can be detachably connected to the air inlet grille 210 is provided on the wire routing groove 211.

[0068] In this embodiment, by setting the wire routing channel 211, the wires can be hidden by the cover 800, making the appearance more attractive and preventing them from getting wet and causing short circuits.

[0069] In one embodiment, the wire routing groove 211 is provided with two sets of limiting protrusions 2111 in the middle.

[0070] In this embodiment, by setting a limiting protrusion 2111, the width of the limiting protrusion 2111 is smaller than the width of the wire routing groove 211, which can constrain the wire and prevent the wire from being too scattered during routing.

[0071] In one embodiment, one end of the fixing part 400 is disposed in the base 100, and the other end of the fixing part 400 is provided with a connecting shaft 410. The rotating part 300 is provided with a connecting hole 310 corresponding to the connecting shaft 410, and the rotating part 300 is sleeved on the connecting shaft 410 through the connecting hole 310.

[0072] A first through hole 2112 is provided between the rotating part 300 and the wire routing groove 211, and a second through hole 420 is provided between the fixing part 400 and the base 100. The first through hole 2112 and the second through hole 420 are connected.

[0073] In this embodiment, the wires are routed through the wire routing groove 211 and the rotating part 300 and the fixing part 400. This prevents the wires from being pulled when the fan bracket 200 is rotated, and the wires are hidden, increasing safety.

[0074] The fixing part 400 is a symmetrical two-part assembly design, which is convenient for disassembly and assembly. The two parts are provided with connecting shafts 410 of different diameters. The large-diameter connecting shaft 410 has a hollowed-out center to form a space for the small-diameter connecting shaft 410 to be inserted. One of the parts is provided with a second through hole 420.

[0075] In one embodiment, a fixing member 500 is provided on one side of the rotating part 300, a limiting hole 510 is provided in the middle of the fixing member 500, and a third through hole 520 is provided on one side of the limiting hole 510.

[0076] The fastener 500 is sleeved on the connecting shaft 410, and the first through hole 2112, the second through hole 420, and the third through hole 520 are connected in sequence.

[0077] In this embodiment, by setting a fixing member 500, the diameter of the limiting hole 510 is equal to or slightly smaller than the connecting shaft 410 (or the connecting shaft 410 with a large diameter), the fixing member 500 is sleeved on the connecting shaft 410, and the fixing member 500 is connected to the rotating part 300. When the rotating part 300 rotates, the fixing member 500 rotates along with it, and the third wire hole 520 rotates along with it, so as not to pull the wire.

[0078] Furthermore, the diameter of the limiting hole 510 is equal to or slightly smaller than that of the connecting shaft 410, which increases the friction between the fixing part 500 and the connecting shaft 410. After the rotating part 300 rotates, the fan bracket 200 will not fold back under the action of gravity and can be fixed at an angle.
