The lampshade 133 is fixedly connected to the lamp holder 131 by fastening screws. The lamp bead 132 is arranged between the lampshade 133 and the lamp holder 131, and the lamp bead 132 is pressed and fixed by assembling the lampshade 133 and the lamp holder 131. The lamp bead 132 is connected to the circuit in the fan body 1 through a wire (not shown in the drawings) to obtain electrical energy from the fan body 1. One end face of the lamp bead 132 is exposed from the lampshade 133 for lighting.

[0030] It should be noted that a rechargeable battery (not shown in the drawings) is disposed in the fan body 1, and the lamp bead 132 is connected to the rechargeable battery through a wire, so that the lamp bead 132 is powered on and emits light. In this embodiment, two lighting assemblies 13 are provided, and the two lighting assemblies 13 are symmetrically arranged. The rechargeable battery is a lithium battery, and the lamp bead 132 is an LED lamp.

[0031] Please continue reading Figures 2 to 4In one embodiment, a mounting hole 14 is provided on the fan body 1. A shaft head 1311 is protrudingly provided on the end surface of the lamp holder 131 close to the fan body 1, and a limiting protrusion 1312 is protrudingly provided on the outer wall of the shaft head 1311 away from the lamp cover 133. The limiting protrusion 1312 enters the interior of the fan body 1 through the mounting hole 14 and abuts against the inner wall of the fan body 1, thereby limiting the lamp holder 131 to prevent the lamp holder 131 from being separated from the mounting hole 14.

[0032] In this embodiment, the fan body 1 includes: an upper shell 15 and a lower shell 16. The upper shell 15 and the lower shell 16 are connected by fastening screws to form a cylindrical fan body 1. A portion of the mounting hole 14 is respectively provided on the upper shell 15 and the lower shell 16. After the upper shell 15 and the lower shell 16 are matched, the mounting hole 14 is also combined and formed. When the lamp holder 131 is installed, it is first matched with a portion of the mounting hole 14 provided on the lower shell 16 so that the limiting protrusion 1312 is located inside the lower shell 16, and then the upper shell 15 and the lower shell 16 are locked and fixed by fastening screws so that the limiting protrusion 1312 is located inside the fan body 1.

[0033] In one embodiment, a first protrusion 1313 is provided on the side of the shaft head 1311 away from the limiting protrusion 1312. An annular boss is provided on the inner wall of the mounting hole 14, and a second protrusion 141 is provided on the annular boss. The first protrusion 1313 is used to cooperate with the second protrusion 141 to prevent the lamp holder 131 from over-rotating.

[0034] See also Figures 5 to 7 In one embodiment, the connecting component 2 includes: a first connecting member 21 and a second connecting member 22. Specifically, the first connecting member 21 is fixedly connected to the mounting portion 11. A card interface 211 is provided on the first connecting member 21. The second connecting member 22 is connected to an end of the folding bracket 3 close to the fan body 1. A card connection column 221 is provided on the second connecting member 22. When the first connecting member 21 and the second connecting member 22 are assembled, the card connection column 221 cooperates with the card interface 211 to realize a detachable assembly between the first connecting member 21 and the second connecting member 22.

[0035] In one embodiment, a clamping platform 2111 is protruded on the inner side wall of the clamping interface 211. A clamping joint 2211 is provided on the side of the clamping column 221 close to the first connecting member 21. When the first connecting member 21 and the second connecting member 22 are assembled, the clamping joint 2211 extends into the clamping interface 211 and is clamped with the clamping platform 2111. When the first connecting member 21 and the second connecting member 22 are separated, an external force needs to be applied to the clamping column 221 first, so that the clamping column 221 undergoes elastic deformation, forcing the clamping joint 2211 to separate from the clamping platform 2111, and then the first connecting member 21 and the second connecting member 22 are separated.

[0036] In one of the embodiments, a clearance opening 220 is provided on the side wall of the second connecting member 22, and a clamping column 221 is provided in the clearance opening 220, so that when the clamping column 221 is clamped or separated from the clamping interface 211, there is enough space for the clamping column 221 to undergo elastic deformation, which is beneficial to the disassembly and assembly of the first connecting member 21 and the second connecting member 22.

[0037] Please continue reading Figures 5 to 7 In one embodiment, a mounting platform 212 is protrudingly provided on the end surface of the first connecting member 21 close to the fan body 1, and a mounting cavity 2121 is provided on the mounting platform 212. Three mounting columns 2122 are provided inside the mounting cavity 2121. Three fastening screws pass through the mounting columns 2122 and are fixedly connected to the mounting portion 11, thereby realizing a fixed connection between the first connecting member 21 and the mounting portion 11.

[0038] In one embodiment, a positioning hole 213 is provided on the first connecting member 21 near the second connecting member 22, and a positioning column 222 is correspondingly provided on the second connecting member 22. When the first connecting member 21 and the second connecting member 22 are assembled, the positioning column 222 is assembled with the positioning hole 213, which not only enables the clamping column 221 to be quickly aligned with the clamping interface 211, facilitating the connection between the clamping column 221 and the clamping interface 211, but also improves the stability of the first connecting member 21 and the second connecting member 22 after assembly.

[0039] See also Figure 5 In one embodiment, the folding bracket 3 includes: a first bracket 31, a second bracket 32 ​​and a first damping shaft 33, wherein the first bracket 31 is rotatably assembled with the second bracket 32 ​​through the first damping shaft 33, and the first bracket 31 and the second bracket 32 ​​can be fixed at the rotated position after being rotated, which is beneficial to the adjustment of the air supply angle and air supply height of the fan body 1.

[0040] See also Figure 5 , Figure 8 and Fig. 9 In one embodiment, the first bracket 31 includes: a first assembly portion 311, a first connecting arm 312, a second connecting arm 313, a first side cover 314 and a second side cover 315. The first connecting arm 312 and the second connecting arm 313 are respectively connected to two opposite side walls of the first assembly portion 311, so that the first bracket 31 is C-shaped as a whole, and the end surface of the first connecting arm 312 away from the first assembly portion 311 is substantially parallel to the end surface of the second connecting arm 313 away from the first assembly portion 311. The first assembly portion 311 is rotatably assembled with the second bracket 32 ​​through the first damping shaft 33. The first side cover 314 and the second side cover 315 are detachably connected to the first connecting arm 312 and the second connecting arm 313, respectively.

[0041] Specifically, the first connecting arm 312 is provided with a first plug-in column 3121, and the first side cover 314 is correspondingly provided with a first plug-in slot 3141 adapted to the first plug-in column 3121. Both ends of the first side cover 314 are provided with a first clamping block 3142, and correspondingly, the first connecting arm 312 is provided with a first clamping hole 3122 adapted to the first clamping block 3142. The first side cover 314 is adapted to the first plug-in column 3121 through the first plug-in slot 3141 and the first clamping block 3142 and the first clamping hole 3122, so as to achieve detachable assembly with the first connecting arm 312. The second connecting arm 313 is provided with a second plug-in column 3131, and the second side cover 315 is correspondingly provided with a second plug-in slot 3151 adapted to the second plug-in column 3131. The second side cover 315 is provided with a second clamping block 3152 at both ends, and correspondingly, the second connecting arm 313 is provided with a second clamping hole 3132 adapted to the second clamping block 3152. The second side cover 315 is detachably assembled with the second connecting arm 313 by adapting the second plugging slot 3151 to the second plugging column 3131 and the second clamping block 3152 to the second clamping hole 3132.

[0042] See also Figure 5 , Fig.10 and Fig.11 In one embodiment, the second bracket 32 ​​includes: a first body 321, a second body 322, a third side cover 323 and a fourth side cover 324. The first body 321 and the second body 322 are respectively connected to the two ends of the first damping shaft 33. The third side cover 323 is detachably connected to the first body 321. The fourth side cover 324 is detachably connected to the second body 322.

[0043] It should be noted that the end of the first body 321 away from the first damping shaft 33 can be connected to the end of the second body 322 away from the first damping shaft 33, so that the second bracket 32 ​​can be used as a base of the folding fan. Obviously, the end of the first body 321 away from the first damping shaft 33 can also be arranged opposite to the end of the second body 322 away from the first damping shaft 33, so that the second bracket 32 ​​is connected to other structures (such as a base, a clip, etc.).

[0044] In one embodiment, the first body 321 is provided with a third plug-in column 3211, and the third side cover 323 is correspondingly provided with a third plug-in slot 3231. The third side cover 323 is also provided with a third clamping block 3232, and the first body 321 is correspondingly provided with a third clamping hole 3212. The third side cover 323 is adapted to the third plug-in column 3211 and the third plug-in slot 3231 and the third clamping block 3232 and the third clamping hole 3212, so as to achieve detachable assembly with the first body 321. Similarly, the second body 322 is provided with a fourth plug-in column 3221, and the fourth side cover 324 is correspondingly provided with a fourth plug-in slot 3241, and the fourth side cover 324 is also provided with a fourth clamping block 3242, and the second body 322 is correspondingly provided with a fourth clamping hole 3222.

[0045] It should be noted that, in the present embodiment, the first bracket 31 is roughly rectangular, and similarly, the second bracket 32 ​​is also roughly rectangular, and the size of the second bracket 32 ​​is larger than the size of the first bracket 31, so that after the folding bracket 3 is folded, the first bracket 31 can be accommodated in the rectangular space formed by the second bracket 32, which is conducive to the storage of the folding bracket 3. In other embodiments, the approximate shape formed by the first bracket 31 and the second bracket 32 ​​can also be a geometric shape such as a circle or a triangle, and the approximate shape formed by the first bracket 31 can be the same as or different from the approximate shape formed by the second bracket 32. The first bracket 31 only needs to be able to be accommodated in the space surrounded by the geometric shape formed by the second bracket 32 ​​after folding.

[0046] See also Figure 5 , Figures 8 to 11 In one embodiment, the first damping shaft 33 includes: a first rotating shaft 331, a first shaft seat 332, a second shaft seat 333, a first shaft body 334, a second shaft body 335 and a first elastic member 336. The first rotating shaft 331 passes through the first shaft seat 332, the second shaft seat 333, the first shaft body 334, the second shaft body 335 and the first elastic member 336. The first elastic member 336 is arranged between the first shaft body 334 and the second shaft body 335 and squeezes them to both sides, so that the first shaft body 334 and the first shaft seat 332 and the second shaft body 335 and the second shaft seat 333 generate interaction forces.

[0047] Specifically, the first rotating shaft 331 is provided with a limiting portion at both ends, which are a first limiting portion 3311 and a second limiting portion 3312 respectively. The first shaft seat 332 is sleeved on the first rotating shaft 331 and abuts against the first limiting portion 3311. The second shaft seat 333 is sleeved on the first rotating shaft 331 and abuts against the second limiting portion 3312. The first shaft seat 332 and the second shaft seat 333 are both connected to the second bracket 32. The first shaft body 334 is sleeved on the first rotating shaft 331 and is located between the first shaft seat 332 and the second shaft seat 333. The first shaft body 334 is connected to the first bracket 31, and one end face thereof abuts against the first shaft seat 332. The second shaft body 335 is sleeved on the first rotating shaft 331 and is located between the first shaft seat 332 and the second shaft seat 333. The second shaft body 335 is also connected to the first bracket 31, and one end face thereof abuts against the second shaft seat 333. The first shaft body 334 and the second shaft body 335 can both rotate around the first rotation axis 331 relative to the first shaft seat 332 and the second shaft seat 333. The first elastic member 336 is disposed between the first shaft body 334 and the second shaft body 335.

[0048] In one embodiment, the first rotating shaft 331 includes: a first shaft core 3313 and a first end 3314. Specifically, the first shaft core 3313 sequentially passes through the first shaft seat 332, the first shaft body 334, the first elastic member 336, the second shaft body 335 and the second shaft seat 333. The first limiting portion 3311 is connected to an end of the first shaft core 3313 away from the first end 3314. The first end 3314 is threadedly assembled with the first shaft core 3313, and the second limiting portion 3312 is connected to an end of the first end 3314 away from the first limiting portion 3311.

[0049] It should be noted that, in this embodiment, the first elastic member 336 is a spring. After the first damping shaft 33 is assembled, the distance between the first limiting portion 3311 and the second limiting portion 3312 is a fixed value, so that the first shaft seat 332, the second shaft seat 333, the first shaft body 334, the second shaft body 335 and the first elastic member 336 are confined in a fixed area. In other embodiments, the first elastic member 336 can also be a spring block or a spring sheet.

[0050] Specifically, one end of the first elastic member 336 abuts against the first shaft 334, and the other end abuts against the second shaft 335. In addition, in the first damping shaft 33, the first elastic member 336 is in a compressed state, and the elastic potential energy generated by its compression can squeeze the first shaft 334 toward the first shaft seat 332, and squeeze the second shaft 335 toward the second shaft seat 333, so that the first shaft 334 and the first shaft seat 332 and the second shaft 335 and the second shaft seat 333 generate interaction forces, thereby fixing the first bracket 31 and the second bracket 32 ​​in the rotated position. The first damping shaft 33 set in this way can avoid looseness, improve the overall support stability of the folding bracket 3, and facilitate the use of the folding fan.

[0051] It should be noted that, under the action of the first elastic member 336, a force is generated between the first shaft body 334 and the first shaft seat 332 and between the second shaft body 335 and the second shaft seat 333, and the friction force of rotation between the first shaft body 334 and the first shaft seat 332 and between the second shaft body 335 and the second shaft seat 333 is increased, thereby enabling the first bracket 31 and the second bracket 32 ​​to be fixed in the rotated position.

[0052] It should also be noted that, during the manufacturing process or during use, the friction between the first shaft seat 332 and the first shaft body 334 and between the second shaft seat 333 and the second shaft body 335 can be adjusted by replacing the first elastic member 336 with different elastic forces or the first elastic member 336 with different lengths, so as to adjust the rotation tightness of the folding bracket 3. In this way, the problem of frequent loosening of the first damping shaft 33 due to the vibration generated when the fan body 1 is working and the gravity of the fan body 1 itself, which ultimately leads to the inconvenience of using the folding fan, can be avoided, which is beneficial to the use and maintenance of the folding fan.

[0053] Please continue reading Figure 5 , Figures 8 to 11 In one embodiment, a first receiving groove 3341 is formed on one side of the first shaft body 334 close to the second shaft body 335 along the axis direction of the first rotating shaft 331.

[0067] The second damping shaft 35 includes a second rotating shaft 351 , a third shaft seat 352 , a fourth shaft seat 353 , a third shaft body 354 , a fourth shaft body 355 and a second elastic member 356 .

[0068] Specifically, two ends of the second rotating shaft 351 are provided with limiting parts, which are the third limiting part 3511 and the fourth limiting part 3512 respectively. The third shaft seat 352 is sleeved on the second rotating shaft 351 and abuts against the third limiting part 3511. The fourth shaft seat 353 is sleeved on the second rotating shaft 351 and abuts against the fourth limiting part 3512. The third shaft seat 352 and the fourth shaft seat 353 are both connected to the first bracket 31. The third shaft body 354 is sleeved on the second rotating shaft 351 and is located between the third shaft seat 352 and the fourth shaft seat 353. The third shaft body 354 is connected to the second connecting member 22. One end surface of the third shaft body 354 abuts against the third shaft seat 352. The fourth shaft body 355 is sleeved on the second rotating shaft 351 and is located between the third shaft body 354 and the fourth shaft seat 353. The fourth shaft body 355 is connected to the second connecting member 22. One end surface of the fourth shaft body 355 abuts against the fourth shaft seat 353. The third shaft body 354 and the fourth shaft body 355 can rotate relative to the third shaft seat 352 and the fourth shaft seat 353 around the second rotation axis 351.

The second end 3514 is threadedly assembled with the second shaft core 3513, and the fourth limiting portion 3512 is connected to an end of the second end 3514 away from the third limiting portion 3511.

[0070] It should be noted that, in this embodiment, the second elastic member 356 is a spring. After the second damping shaft 35 is assembled, the distance between the third limiting portion 3511 and the fourth limiting portion 3512 is a fixed value, so that the third shaft seat 352, the fourth shaft seat 353, the third shaft body 354, the fourth shaft body 355 and the second elastic member 356 are confined in a fixed area. In other embodiments, the second elastic member 356 can also be a spring block or a spring sheet.

In the second damping shaft 35, the second elastic member 356 is in a compressed state, and the elastic potential energy generated by its compression can squeeze the third shaft 354 toward the third shaft seat 352, and squeeze the fourth shaft 355 toward the third shaft 354, so that friction is generated between the third shaft 354 and the third shaft seat 352 and between the fourth shaft 355 and the fourth shaft seat 353, thereby fixing the first bracket 31 and the second connecting member 22 in the rotated position. The second damping shaft 35 set in this way can avoid looseness, improve the overall support stability of the folding bracket 3, and facilitate the use of the folding fan.

[0072] It should also be noted that, during the manufacturing process or during use, the friction between the third shaft seat 352 and the third shaft body 354 and between the fourth shaft seat 353 and the fourth shaft body 355 can be adjusted by replacing the first elastic member 336 with different elastic forces or the first elastic member 336 with different lengths, so as to adjust the rotation tightness of the folding bracket 3. In this way, the loosening of the second damping shaft 35 caused by the vibration generated when the fan body 1 is working and the gravity of the fan body 1 itself can be avoided, which ultimately leads to the inconvenience of using the folding fan, and is beneficial to the use and maintenance of the folding fan.

The third positioning block 3521 is adapted to the third positioning groove 3124, so that the third shaft seat 352 is limitedly installed in the third mounting opening 3123. Similarly, a fourth positioning groove 3134 is provided on the inner side wall of the fourth mounting opening 3133, and a fourth positioning block 3531 is provided on the outer side wall of the fourth shaft seat 353. The fourth positioning block 3531 is adapted to the fourth positioning groove 3314, so that the fourth shaft seat 353 is limitedly installed in the fourth mounting opening 3133. In this way, the third shaft seat 352, the fourth shaft seat 353 and the first bracket 31 can remain relatively fixed when the second connecting member 22 rotates, so as to facilitate the rotation of the connecting assembly 2.

[0081] In one embodiment, the second assembly portion 223 is further provided with a second receiving groove 2233, and two second receiving grooves 2233 are provided, which are respectively located at the two ends of the second assembly hole 2231, and the two second receiving grooves 2233 are both connected to the second assembly hole 2231. Two second damping rings 36 are also provided between the second assembly hole 2231 and the first connecting arm 312 and between the second assembly hole 2231 and the second connecting arm 313. Specifically, one of the second damping rings 36 is tightly fixed in the corresponding second receiving groove 2233 by the first connecting arm 312, and the other second damping ring 36 is tightly fixed in the corresponding second receiving groove 2233 by the second connecting arm 313. It should be noted that the provision of the second damping ring 36 enables the first bracket 31 and the second connecting member 22 to rotate to generate a damping force, further improving the stability of the folding bracket 3 when supporting.

[0082] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0083] 1) The fan body and the folding bracket are assembled through a connecting component, so that the fan body and the folding bracket can be detachably assembled. On the one hand, the user can replace the folding bracket as needed to avoid the folding fan from being unable to be used normally due to damage to the folding bracket; on the other hand, when the folding fan is stored or packaged, the folding bracket can be separated from the fan body, thereby facilitating carrying or transportation.

[0084] 2) The first damping shaft passes through the first rotating shaft and defines the first shaft seat, the second shaft seat, the first shaft body, the second shaft body and the first elastic member, so that the first elastic member located between the first shaft body and the second shaft body is in a compressed state. In this way, the first shaft body and the second shaft body are respectively pressed against the first shaft seat and the second shaft seat under the elastic force of the first elastic member, so that the first shaft body and the second shaft body produce a damping effect when rotating. The first bracket and the second bracket are rotatably assembled through the first damping shaft, so that the folding bracket can provide stable support when the fan body is in use, thereby avoiding the problem of the rotating structure of the folding fan being frequently loosened due to the vibration generated by the operation of the fan body and the gravity of the fan body itself, and has the advantages of good support stability, not easy to loosen, and easy fan use.

[0085] 3) By providing the first damping part and the second damping part, the first bracket and the second bracket can be fixed at the rotated position, and by cooperating with the first tooth surface and the second tooth surface, the folding bracket can provide more stable support for the fan body.

[0086] 4) The first damping part and the second damping part are both tooth surfaces. When the first bracket rotates relative to the second bracket, when the tooth top of the first tooth surface is opposite to the tooth top of the second tooth surface, the first elastic member is further compressed, so that the first damping part and the second damping part can rotate relative to each other. When the tooth root of the first tooth surface is opposite to the tooth top of the second tooth surface, the first elastic member increases the pressure between the first damping part and the second damping part, thereby realizing the locking of the folding angle of the first bracket and the second bracket.

[0087] 5) The setting of the first damping ring can not only avoid the direct connection between the first bracket and the second bracket, thereby preventing the first bracket or the second bracket from being worn, but also provide damping force between the first bracket and the second bracket again, further improving the stability of the folding bracket support.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
