[0038] In the related art, most fans can be provided with a shaking device on a bracket. By connecting the shaking device to the fan housing, the shaking device can drive the fan and the fan blades to swing in the up and down directions, so that the fan can achieve the effect of up and down air blowing and increase the air outlet range of the fan. However, due to the relatively large overall weight of the fan and the fan blades, the shaking device usually needs to use a motor with a relatively large power to drive the fan and the fan blades to rotate against gravity, resulting in the shaking device usually needing to be configured with a high-power motor with a relatively large volume, increasing the overall volume of the fan, unable to well achieve the simple design of the fan, and reducing the practicability of the fan. To solve the above problems, the present utility model proposes a shaking device 100.

[0039] Please refer to Figures 1 to 13, in an embodiment of the present utility model, the swing device 100 includes a first mounting member 10, a second mounting member 30, a swing mechanism 50 and an elastic structure 70. The first mounting member 10 is used to connect to the support frame 200, and the first mounting member 10 has a first normal line 10a; the second mounting member 30 is used to connect to the fan assembly 400, and the second mounting member 30 has a second normal line 31, and the second normal line 31 is arranged at an angle with the first normal line 10a; the swing mechanism 50 connects the first mounting member 10 and the second mounting member 30, and drives the second mounting member 30 to swing relative to the first mounting member 10 to change the included angle formed by the first normal line 10a and the second normal line 31; the elastic structure 70 connects the first mounting member 10 and the second mounting member 30. It can be understood that the fan assembly 400 may include a fan, fan blades and a protective cover, etc. By using the fan to drive the fan blades to rotate, the stable blowing operation of the fan 1000 is realized. At this time, the protective cover can wrap and protect the fan blades, and the rotating shaft of the fan passes through the protective cover to connect the fan blades; or the protective cover can wrap the fan and the fan blades to achieve a better protective effect and effectively reduce the safety hazards of the operation of the fan 1000. The fan 1000 can connect and install the swing device 100 on the support frame 200, and fix the fan and / or the protective cover of the fan assembly 400 to the swing device 100. Then, under the support and fixation of the support frame 200, the swing device 100 can stably drive the fan assembly 400 to rotate and swing, realizing the swing effect of the fan 1000 and better increasing the blowing range of the fan 1000.

[0040] In the present application, the swing device 100 may include a first mounting member 10 and a second mounting member 30. The first mounting member 10 may be a columnar structure connected to the support frame 200, and the second mounting member 30 may be a seat frame structure connected and fixed to the fan and / or the protective cover. The geometric center normal line of the first mounting member 10 can be set as the first normal line 10a, and the geometric center normal line of the second mounting member 30 can be set as the second normal line 31. At this time, when the second mounting member 30 is connected to the fan of the fan 1000, the central axis of the rotating shaft of the fan can also be arranged on the same straight line as the second normal line 31, so that the swing device 100 can be better connected and installed at the center of gravity of the fan assembly 400, and better improve the overall structural stability of the fan 1000. After the first mounting member 10 and the second mounting member 30 are connected, the first normal line 10a and the second normal line 31 can be arranged at an angle, so that the fan assembly 400 can be installed on the vertical support frame 200 through the swing device 100 to maintain horizontal blowing and ensure the stable operation of the fan 1000.

[0041] By arranging a swing mechanism 50 between the first mounting member 10 and the second mounting member 30 and connecting the swing mechanism 50 to the first mounting member 10 and the second mounting member 30, the swing mechanism 50 can be used to connect and drive the second mounting member 30 to rotate relative to the first mounting member 10. The second mounting member 30 can swing towards or away from the first mounting member 10 in the height direction of the fan 1000, changing the angle between the first normal line 10a and the second normal line 31. Furthermore, under the driving action of the swing mechanism 50, the second mounting member 30 can drive the fan assembly 400 to swing up and down in the height direction of the fan 1000, realizing the up-and-down swing air-sweeping function of the fan 1000 and effectively increasing the air-blowing range of the fan 1000.

[0042] By using an elastic structure 70 to connect the first mounting member 10 and the second mounting member 30, the elastic structure 70 can be a spring, a torsion spring, a reed or other structures. When the fan 1000 is in a horizontal air-blowing state or a state of blowing obliquely downward, the gravity of the fan assembly 400 and the second mounting member 30 acts on the elastic structure 70, causing the elastic structure 70 to undergo a certain elastic deformation. At this time, the swing mechanism 50 can play a certain role in limiting and self-locking the relative rotation of the first mounting member 10 and the second mounting member 30, so that the elastic structure 70 can maintain the elastic deformation that occurs at this time, ensuring the stable horizontal air-blowing or the operation of blowing obliquely downward of the fan 1000.

[0043] When the swing mechanism 50 drives the second mounting member 30 to swing relative to the first mounting member 10, as the second mounting member 30 moves upward, the elastic structure 70 can recover a certain elastic deformation and exert a force on the second mounting member 30 and the fan assembly 400, so that part of the elastic potential energy exerted by the elastic structure 70 on the second mounting member 30 cancels out part of the gravitational potential energy exerted by the fan assembly 400 on the second mounting member 30. Furthermore, the elastic structure 70 can play a certain auxiliary role when the swing mechanism 50 drives the second mounting member 30 to lift and rotate, so that the swing mechanism 50 can drive the second mounting member 30 to swing smoothly with lower power consumption. The swing mechanism 50 can adopt a low-power drive device 53 with a small volume, realizing the miniaturized design of the swing device 100, effectively reducing the overall volume of the fan 1000, and improving the practicability and reliability of the swing device 100.

[0044] The technical solution of the present utility model is to arrange an elastic structure 70 in the swing device 100 to connect the first mounting member 10 and the second mounting member 30. When the swing device 100 supports the fan assembly 400 to blow horizontally or obliquely downward, the gravity of the fan assembly 400 and the second mounting member 30 is used to squeeze the elastic structure 70, causing the elastic structure 70 to undergo a certain elastic deformation. Then, when the swing mechanism 50 drives the second mounting member 30 to lift and swing relative to the first mounting member 10, the elastic structure 70 can recover a certain elastic deformation as the second mounting member 30 rises, and the force for the elastic structure 70 to recover the elastic deformation can be applied to the second mounting member 30 to offset part of the gravity received by the second mounting member 30, so that the swing mechanism 50 can stably drive the second mounting member 30 to lift and swing with relatively low power consumption. This is conducive to arranging the swing mechanism 50 with a low-power drive device 53 of a smaller volume, effectively reducing the overall volume of the swing device 100, realizing the simple design of the fan 1000, and further improving the practicability and reliability of the swing device 100.

[0045] Further, the first mounting member 10 includes a first connecting column 11, a second connecting column 13 and a steering mechanism 15. The second connecting column 13 is stacked with the first connecting column 11. One end of the second connecting column 13 facing away from the first connecting column 11 is connected to the swing mechanism 50. The steering mechanism 15 connects the first connecting column 11 and the second connecting column 13 and drives the second connecting column 13 to rotate relative to the first connecting column 11.

[0046] In this embodiment, the first mounting member 10 can be formed by the first connecting column 11 and the second connecting column 13 that are stacked on each other. The first connecting column 11 and the second connecting column 13 can be sleeve structures with a certain cavity, so that the steering mechanism 15 can be installed in the inner cavities of the first connecting column 11 and the second connecting column 13, and connect the first connecting column 11 and the second connecting column 13. By connecting and fixing the first connecting column 11 to the support frame 200, the steering mechanism 15 can be electrically driven to operate, so that the steering mechanism 15 drives the second connecting column 13 to rotate relative to the first connecting column 11 in the horizontal direction. Furthermore, by connecting the end of the second connecting column 13 facing away from the first connecting column 11 to the swing mechanism 50 and the second mounting member 30, the second mounting member 30 can be driven to rotate together when the second connecting column 13 rotates horizontally, realizing the horizontal swing function of the fan 1000, enabling the fan 1000 to achieve a larger blowing range, and further improving the practicability and reliability of the swing device 100. By arranging the steering mechanism 15 in the first mounting member 10 to drive the second connecting column 13 to rotate, and making the second connecting column 13 drive the second mounting member 30 to rotate horizontally, the swing device 100 can integrate the up-and-down swing function and the horizontal swing function. Furthermore, the swing device 100 can achieve the swing effect of multiple degrees of freedom, effectively increasing the blowing range of the fan 1000, so that the fan 1000 can better meet the user's usage requirements, and further improving the practicability and reliability of the swing device 100. By integrating the horizontal swing drive component on the first mounting member 10 of the swing device 100 and arranging the swing mechanism 50 between the first mounting member 10 and the second mounting member 30 to achieve the up-and-down swing function, the swing device 100 can more compactly arrange multiple drive components within a smaller volume setting, which is beneficial to better realizing the miniaturized design of the swing device 100. Furthermore, it can better reduce the overall volume of the fan 1000 and further improve the practicability of the swing device 100.

[0047] Referring to Figures 2 to 4 , in an embodiment of the present invention, the first mounting member 10 is provided with a mounting seat 131, the second mounting member 30 is provided with a connecting web 33, the swing mechanism 50 includes a rotating shaft 51 and a driving device 53. The rotating shaft 51 connects the mounting seat 131 and the connecting web 33, and the driving device 53 connects and drives the second mounting member 30 to swing relative to the first mounting member 10 around the central axis of the rotating shaft 51.

[0048] In this embodiment, a mounting seat 131 can be convexly provided on one end face of the first mounting member 10 of the shaking device 100. The mounting seat 131 can be a sheet metal structure with a certain structural support strength, or can be a block structure with a certain thickness, etc. And a connecting web 33 that cooperates and abuts against the outer wall or inner wall of the mounting seat 131 is provided on the side of the second mounting member 30 close to the first mounting member 10. By arranging the swing mechanism 50 with a rotating shaft 51 connecting the mounting seat 131 and the connecting web 33, the central axis of the rotating shaft 51 can be used as the central axis for the second mounting member 30 to swing relative to the first mounting member 10 in the height direction.

[0049] At this time, by arranging the driving device 53 of the swing mechanism 50 between the mounting seat 131 and the connecting web 33, the driving device 53 can be arranged on the mounting seat 131 to connect and drive the connecting web 33, or can be arranged on the connecting web 33 to drive the connecting web 33 to rotate around the rotating shaft 51, or can be arranged on the rotating shaft 51 to directly drive the connecting web 33 to rotate relative to the mounting seat 131. Furthermore, under the driving action of the driving device 53, the connecting web 33 can drive the second mounting member 30 and the fan assembly 400 to rotate around the central axis of the rotating shaft 51 relative to the first mounting member 10, realizing that the shaking device 100 drives the fan assembly 400 to stably swing in the height direction, ensuring the swinging operation of the fan 1000, and further improving the structural stability and reliability of the shaking device 100. Among them, the swing mechanism 50 can be provided with bearings on the mounting seat 131 or the connecting web 33, and the rotating shaft 51 is arranged to pass through the bearings. Under the action of the bearings, the second mounting member 30 can rotate more smoothly relative to the first mounting member 10, reducing the burden of rotational friction force received by the second mounting member 30, and further improving the structural reliability of the shaking device 100.

[0050] By using the rotating shaft 51 to connect the mounting seat 131 and the connecting web 33, under the elastic reset action of the elastic structure 70, the driving device 53 can drive and lift the second mounting member 30 more stably, so that the first mounting member 10 can bear part of the force received by the second mounting member 30 through the rotating shaft 51, better avoiding the situation that the load received by the second mounting member 30 is too large and there is a certain probability of damage, and further improving the practicability and reliability of the shaking device 100.

[0051] Furthermore, referring to Figure 14, bearings 511 are sleeved on both ends of the rotating shaft 51, and the bearings 511 are connected to the mounting seat 131 and the connecting web 33. In this embodiment, by using the bearings 511 at both ends of the bearing 51 to connect with the mounting seat 131 and the connecting web 33, the friction between the rotating shaft 51 and the mounting seat 131 and the connecting web 33 can be better reduced under the action of the bearings 511, so that the driving device 53 can drive the second mounting member 30 to swing relative to the first mounting member 10 around the central axis of the rotating shaft 51 more smoothly, making the load of the driving device 53 more uniform and gentle, and improving the overall service life of the driving device 53 and the fan 1000.

[0052] Refer to Figure 3 and Figure 5 , in an embodiment of the present utility model, the elastic structure 70 is connected to the rotating shaft 51. The elastic structure 70 is provided with a first fixed end 71 and a second fixed end 73. The first fixed end 71 is connected to the first mounting member 10, and the second fixed end 73 is connected to the second mounting member 30.

[0053] In this embodiment, the elastic structure 70 can be a torsion spring wound around the rotating shaft 51; or a reed can be passed through or fixedly connected to the rotating shaft 51; or, the elastic structure 70 can adopt the structure of a compression spring, and the compression spring can be arranged on one side of the rotating shaft 51 close to the fan assembly 400; or, the elastic structure 70 can adopt the structure of a tension spring, and the tension spring can be arranged on one side of the rotating shaft 51 facing away from the fan assembly 400. Thus, the elastic structure 70 can be installed on the rotating shaft 51, and the first fixed end 71 and the second fixed end 73 are respectively connected and fixed to the first mounting member 10 and the second mounting member 30, so that the elastic structure 70 can be more firmly installed on the first mounting member 10 and the second mounting member 30, ensuring the stable and reliable support of the elastic structure 70 for the second mounting member 30, and further improving the structural stability and reliability of the swing head device 100. At this time, when the second mounting member 30 swings downward, the elastic structure 70 can be subjected to the gravity of the second mounting member 30 and the fan assembly 400, causing the second fixed end 73 to approach the first fixed end 71, and the elastic structure 70 is compressed and elastically deformed. Then, when the driving device 53 drives the second mounting member 30 to swing upward, the elastic structure 70 can be released, and the second fixed end 73 moves in a direction away from the first fixed end 71 to restore the elastic deformation of the elastic structure 70, so that the elastic structure 70 can stably support the second mounting member 30, realizing the stable swing operation of the swing head device 100, and further improving the practicability and reliability of the swing head device 100.

[0054] Refer to Figure 5, in an embodiment of the present utility model, at least two fixing structures 133 are provided inside the first mounting member 10. The at least two fixing structures 133 are arranged at intervals along the swinging direction of the second mounting member 30 relative to the first mounting member 10, and the first fixed end 71 is connected to any one of the fixing structures 133.

[0055] In this embodiment, the fixing structure 133 can be a jack for the first fixed end 71 to be inserted and fixed, or can be a clip for clamping and fixing the first fixed end 71, etc. By arranging the at least two fixing structures 133 at intervals on the first mounting member 10 along the swinging path of the second mounting member 30, at this time, by changing the installation position of the first fixed end 71 of the elastic structure 70 among the at least two fixing structures 133, the degree of elastic deformation of the elastic structure 70 under the gravity of the second mounting member 30 and the fan assembly 400 can be adjusted. For example, when the first fixed end 71 is installed on the fixing structure 133 relatively above inside the first mounting member 10, the degree of elastic deformation of the elastic structure 70 can be made larger, and when the first fixed end 71 is installed on the fixing structure 133 relatively below inside the first mounting member 10, the degree of elastic deformation of the elastic structure 70 can be made smaller.

[0056] Furthermore, by changing the installation site of the elastic structure 70 and the first mounting member 10, the adjustment of the degree of elastic deformation of the elastic structure 70 can be realized, so that the swinging device 100 can better adjust the elastic force of the elastic structure 70 according to the gravity of the fan assembly 400 and the second mounting member 30 of the fan 1000, and realize a better auxiliary effect on the driving device 53 to lift the second mounting member 30, so that the fan 1000 can use the swinging device 100 to swing up and down more smoothly.

[0057] Refer to Figure 3 and Figure 4 , in an embodiment of the present utility model, the driving device 53 includes a driving motor 531 and a transmission structure. The driving motor 531 is connected to the mounting seat 131, and the driving motor 531 is provided with a driving wheel 5311; the transmission structure is connected to the connecting web 33, and the transmission structure is provided with a rack 533, and the rack 533 is meshed and connected with the driving wheel 5311.

[0058] In this embodiment, the driving device 53 can mount and fix the driving motor 531 in the mounting seat 131. A driving wheel 5311 can be arranged on the driving shaft of the driving motor 531. By arranging a transmission structure on the side of the connecting web 33 facing the driving motor 531, the transmission structure can be a rack 533 arranged on the plate surface of the connecting web 33. A plurality of engaging teeth cooperating with the driving wheel 5311 can be arranged on the rack 533, and the rack 533 can be arranged with an arc equal to the arc of the swinging path of the second mounting member 30. When the driving motor 531 drives the driving wheel 5311 to rotate, the driving wheel 5311 can be used to engage and drive the rack 533 and the second mounting member 30 to rotate around the rotating shaft 51, realizing the stable swinging operation of the shaking head device 100. By using the gear meshing action of the driving motor 531 and the transmission structure to drive the second mounting member 30 to swing in the up and down direction, the structural arrangement on the second mounting member 30 can be better simplified, which is beneficial to better reducing the overall weight of the second mounting member 30, so that the driving device 53 can drive the second mounting member 30 to swing relative to the first mounting member 10 at a lower working power, ensuring the stable swinging air supply operation of the fan 1000, and further improving the practicability and reliability of the shaking head device 100.

[0059] Referring to Figures 6 to 8 , in some embodiments of the present utility model, one end of the first connecting column 11 facing away from the second connecting column 13 is provided with a first wiring terminal 113, and the first wiring terminal 113 is used to connect the transmission cable 600.

[0060] In this embodiment, when the fan 1000 adopts a detachable structural design of the support frame 200 and the shaking head device 100, the shaking head device 100 can adopt a detachable structure for the wires passing through and connecting the swinging mechanism 50, the steering mechanism 15 and the fan assembly 400 inside and the transmission cable 600 of the adapter, so that when the fan 1000 is disassembled, assembled and stored, the shaking head device 100 and the support frame 200 can be better separated, and the overall volume of the fan 1000 during storage can be better reduced.

[0061] Among them, when the shaking head device 100 is installed on the support frame body 200, one end of the first connecting column 11 facing away from the second mounting column can be connected and fixed to the support frame body 200 by means of threaded cooperation or plug-in cooperation. At this time, a certain space can be set in the support frame body 200 for the transmission cable 600 of the adapter to route. By providing a first wiring terminal 113 on the end face of one end of the first connecting column 11, the end of the transmission cable 600 can be provided with a terminal structure that is adapted to be plugged into the first wiring terminal 113. In this way, the transmission cable 600 can be plugged into the first wiring terminal 113 in the support frame body 200 to achieve stable wiring between the adapter and the shaking head device 100, ensuring the stable operation of the fan 1000 and further improving the practicability and reliability of the shaking head device 100. By providing the first wiring terminal 113 at the end of the first connecting column 11 to cooperate with the transmission cable 600 for plugging and conduction, the transmission cable 600 of the adapter can be accommodated in the support frame body 200, which is beneficial to better avoid the exposure of the cable of the fan 1000, reduce the interference of the cable to the user's activities, and at the same time make the overall structure of the fan 1000 more compact, further improving the aesthetics and practicability of the fan 1000.

[0062] Referring to Figures 10 to 12 , in some other embodiments of the present invention, an installation hole 111 is formed in the first connecting column 11. The steering mechanism 15 is provided with a connecting rotating rod 151. The connecting rotating rod 151 is connected to one end of the second connecting column 13. A part of the structure of the connecting rotating rod 151 is arranged in the installation hole 111. A first bearing 153 and a second bearing 155 are sleeved on the outer periphery of the connecting rotating rod 151. The first bearing 153 and the second bearing 155 are arranged at intervals along the extending direction of the connecting rotating rod 151 and are respectively fixedly abutted against the inner wall of the hole of the installation hole 111. A wire routing channel 1511 is provided in the connecting rotating rod 151. A wire routing long hole 1513 communicating with the wire routing channel 1511 is provided on the outer peripheral side of the connecting rotating rod 151. The wire routing long hole 1513 is arranged between the first bearing 153 and the second bearing 155. A wire groove 1111 is recessed on the inner wall of the hole of the installation hole 111. The notch of the wire groove 1111 is arranged opposite to the wire routing long hole 1513. A wiring hole 115 communicating with the wire groove 1111 is provided on the outer peripheral side of the first connecting column 11.

[0063] In this embodiment, the first connecting column 11 can be connected to other column support frames 200 or the support frames 200 of the frame structure, so that the fan 1000 can operate more stably. By installing and fixing the second connecting column 13 on the steering mechanism 15 and using the steering mechanism 15 to rotate on the first connecting column 11, the steering mechanism 15 can drive the second connecting column 13 to rotate horizontally on the nose assembly, thereby expanding the working range of the electric fan 1000. Among them, an installation hole 111 with a certain length can be opened in the first connecting column 11. By inserting the connecting rod 151 of the steering mechanism 15 into the installation hole 111 and sleeving a first bearing 153 and a second bearing 155 at a certain interval along the extension direction of the connecting rod 151 on the outer periphery of the connecting rod 151, the outer peripheries of the first bearing 153 and the second bearing 155 can be connected and fixed to the inner wall of the hole of the installation hole 111. Thus, under the action of the first bearing 153 and the second bearing 155, the rotational friction between the steering mechanism 15 and the first connecting column 11 can be reduced, ensuring more stable relative rotation between the steering mechanism 15 and the first connecting column 11.

[0064] By providing a wire groove 1111 on the inner wall of the mounting hole 111 of the first connecting column 11, the notch of the wire groove 1111 can be arranged between the first bearing 153 and the second bearing 155. At this time, a wiring hole 115 penetrating through to the wire groove 1111 can be provided on the outer periphery of the first connecting column 11, enabling the transmission wire of the fan 1000 to pass through the wiring hole 115 and enter the wire groove 1111. Furthermore, by forming a wiring channel 1511 with a certain length inside the connecting rotating rod 151 through structural avoidance or by opening an inner hole structure, the wiring channel 1511 can penetrate from the inside of the connecting rotating rod 151 to the end face of the connecting rotating rod 151 arranged inside the second connecting column 13. By providing a long wiring hole 1513 on the outer periphery of the connecting rotating rod 151 that penetrates and communicates with the wiring channel 1511, the long wiring hole 1513 can be arranged to extend a certain length along the rotation direction of the connecting rotating rod 151. The long wiring hole 1513 can be arranged between the first bearing 153 and the second bearing 155, and the notch of the wire groove 1111 on the mounting hole 111 is arranged opposite to the long wiring hole 1513. Thus, after the wire enters the wire groove 1111, it can enter the wiring channel 1511 through the long wiring hole 1513 on the connecting rotating rod 151, enabling the wire to stably pass through the second connecting column 13 to connect the swing mechanism 50, the steering mechanism 15, the fan assembly 400, etc., realizing the wiring of the wires inside the swing device 100 and ensuring the power supply and control of the fan 1000. Among them, since the long wiring hole 1513 extends along the rotation direction of the connecting rotating rod 151, it is beneficial to make the lateral dimension of the long wiring hole 1513 much larger than the outer diameter dimension of the wire. During the process of the steering mechanism 15 driving the second connecting column 13 to rotate, the long wiring hole 1513 can be used to avoid the wire, enabling the wire and the connecting rotating rod 151 to swing relative to each other at the long wiring hole 1513, effectively preventing the wire from being pulled when the steering mechanism 15 rotates or the wire from being wound around the connecting rotating rod 151, so that the wire can be more stably and reliably arranged on the first connecting column 11 and the steering mechanism 15 to ensure the stable operation of the fan 1000.

[0065] Referring to Figures 10 to 12 , in an embodiment of the present utility model, a connecting groove 119 is provided at the end of the first connecting column 11. The wiring hole 115 penetrates through to the inner side wall of the connecting groove 119, and the mounting hole 111 penetrates through to the bottom wall of the connecting groove 119. The wire groove 1111 communicates with the connecting groove 119. A part of the structure of the connecting rotating rod 151 is arranged in the connecting groove 119 and is rotatably connected to the inner side wall of the connecting groove 119.

[0066] In this embodiment, a connection groove 119 may be recessed at the end of the first connection post 11 facing the steering mechanism 15. At this time, an installation hole 111 may be formed below the connection groove 119 in the first connection post 11, and the installation hole 111 may penetrate through to the bottom wall of the connection groove 119. The inner diameter of the installation hole 111 may be set smaller than the inner diameter of the connection groove 119. When the steering mechanism 15 is configured such that the connection rod 151 has a structure that is wider at the top and narrower at the bottom, a portion of the connection rod 151 with a smaller outer diameter at the lower end may be inserted into the installation hole 111, and a portion with a larger outer diameter at the upper end may be limited and arranged within the connection groove 119 to achieve the assembly of the steering mechanism 15 and the first connection post 11. Among them, by making one side of the wire groove 1111 penetrate through to the bottom wall of the connection groove 119, the wire groove 1111 can be communicated with the connection groove 119. At this time, the wiring hole 115 may penetrate through to the inner side wall of the connection groove 119, and the wiring hole 115 can be communicated with the wire groove 1111 within the connection groove 119. Furthermore, after the wire within the swing head device 100 is connected to the cable of the external power supply at the wiring hole 115, it can run through the connection groove 119 and enter the wire groove 1111, enabling the wire to better avoid the first bearing 153 of the connection rod 151 during wiring, and further preventing the wire from interfering with the first bearing 153. And within the connection groove 119, the wire can be arranged as close as possible to the inner side wall of the connection groove 119. The installation hole 111 is arranged in the central area of the connection groove 119. By providing a notch on the outer circumference of the connection rod 151 to avoid the wire or reducing the outer diameter of a part of the structure of the connection rod 151 arranged within the connection groove 119, the wire and the connection rod 151 can be arranged at a certain distance from each other within the connection groove 119, which is beneficial to better avoiding the interference between the wire and the connection rod 151, and further preventing the wire from being pulled or wound around the connection rod 151 due to the rotational force of the connection rod 151 with a certain probability, thus ensuring the stable operation of the fan 1000.

[0067] And by providing a rotating device within the connection groove 119 that is connected to the inner side wall of the connection rod 151 and the connection groove 119, under the driving action of the rotating device, the connection rod 151 can rotate relative to the first connection post 11 within the connection groove 119, so that the steering mechanism 15 can rotate along the central axis of the connection rod 151 to drive the second connection post 13 to rotate, further improving the structural stability and reliability of the swing head device 100.

[0068] Referring to Figure 10 and Figure 12 , in an embodiment of the present utility model, a connection rack 1191 is provided on the inner side wall of the connection groove 119, and the connection rod 151 is further provided with a transmission gear 1515. The transmission gear 1515 is rotatably exposed on the outer peripheral side of the connection rod 151 and is meshed and connected to the connection rack 1191.

[0069] In this embodiment, by providing a connecting rack 1191 on the inner side wall of the connecting groove 119, the connecting rack 1191 can be arranged in an arc shape on the inner side wall of the connecting groove 119, and a plurality of teeth are sequentially provided on the side of the connecting rack 1191 facing the connecting rotating rod 151. The radian of the connecting rack 1191 can be the radian of the rotation of the steering mechanism 15. Furthermore, by providing a rotatable transmission gear 1515 in the connecting rotating rod 151, and using the engagement connection between the transmission gear 1515 and the teeth of the connecting rack 1191, the connecting rotating rod 151 can be rotated on the first connecting column 11 under the rotation of the transmission gear 1515, thus ensuring the stable rotation of the steering mechanism 15 and expanding the air outlet range of the electric fan 1000. Among them, the connecting rack 1191 can be firmly connected to the inner side wall of the connecting groove 119 by hot melting process or adhesive adhesion; or, the connecting rack 1191 can be formed when the first connecting column 11 is integrally molded, which is beneficial to better improving the overall structural strength of the connecting rack 1191 and the first connecting column 11, and further improving the service life of the shaking head device 100. In the connecting groove 119, the wiring hole 115 can be located on the part of the inner side wall of the connecting groove 119 where the connecting rack 1191 is not provided, so that when the wire runs between the wiring hole 115 and the wire passing groove 1111, it can better avoid the connecting rack 1191, preventing the transmission gear 1515 of the connecting rotating rod 151 from interfering with the wire when it rotates in cooperation with the connecting rack 1191, further improving the structural stability and reliability of the shaking head device 100, and realizing a more compact structural design of the shaking head device 100.

[0070] Referring to FIG. 12, in an embodiment of the present invention, the connecting rotating rod 151 includes a shaft body section and a rotating section. The shaft body section is arranged in the mounting hole 111, the shaft body section is sleeved with a first bearing 153 and a second bearing 155, and a wire passing long hole 1513 is provided on the outer peripheral side of the shaft body section; one end of the rotating section is connected to the shaft body section, the other end of the rotating section is connected to the second connecting column 13, and a part of the structure of the rotating section is arranged in the connecting groove 119. The transmission gear 1515 is exposed on the outer peripheral side of the rotating section, and a driving source 157 is arranged in the rotating section. The driving source 157 is connected to the transmission gear 1515 and drives the transmission gear 1515 to rotate.

[0071] In this embodiment, the shaft body section connecting the rotating rod 151 can be a cylindrical structure with an outer diameter smaller than the inner diameter of the mounting hole 111, so that the rotation of the shaft body section of the rotating rod 151 in the mounting hole 111 by sleeving a first bearing 153 and a second bearing 155 on the outer periphery of the shaft body section can well ensure the stable rotation of the steering mechanism 15. The outer diameter of the rotating section can be set to be larger than that of the shaft body section. One end of the rotating section facing away from the shaft body section can be exposed at the notch of the connecting groove 119, and a mounting platform or a mounting bracket and other structures can be arranged on this part of the structure of the rotating section to connect with the second connecting column 13, improving the connection stability and reliability between the steering mechanism 15 and the second connecting column 13, and ensuring the stable drive of the second connecting column 13. Among them, a cavity with a certain volume can be formed in the inner cavity of the rotating section, so that the drive source 157 for driving the rotation of the steering mechanism 15 can be installed in this cavity. The drive source 157 can be a device such as a motor. At this time, the transmission gear 1515 can be connected to the drive shaft of the drive source 157, and a hole structure communicating with its inner cavity can be arranged on the outer periphery of the rotating section, so that the transmission gear 1515 can rotate in this hole structure and be exposed on the outer peripheral side of the rotating section, so that the rotating gear can mesh and rotate with the transmission rack 533 under the drive of the drive source 157, thereby realizing the rotation of the connecting rod 151 in the first connecting column 11 and realizing the horizontal shaking and air blowing of the second connecting column 13. Among them, a wiring channel 1511 can be formed by using the installation gap between the drive source 157 and other components inside the cavity of the rotating section, so that the wire can be connected to the second connecting column 13 through the wiring channel 1511 in the shaft body section and the rotating section, ensuring the stable power supply and control of the fan 1000, further improving the structural stability and reliability of the shaking device 100, and realizing a more compact structural design of the shaking device 100.

[0072] Refer to Figure 10 , in an embodiment of the present utility model, the first connecting column 11 is provided with a second wiring terminal 117, and the second wiring terminal 117 is installed in the wiring hole 115.

[0073] In this embodiment, in order to better achieve the disassembly, storage and transportation of the fan 1000, the whole-machine cable of the fan 1000 can be divided into internal wires arranged in the swing device 100 and a transmission cable 600 for the adapter to connect to an external power supply. At this time, by setting a second terminal 117 at the wiring hole 115 and at least part of its structure being accommodated in the connection groove 119, the second terminal 117 can be a socket or a plug. Specifically, it can be a DC power plug or a DC power socket, or it can be a USB (Universal Serial Bus) plug or a USB socket, etc. At this time, a plug or a socket that mates with the second terminal 117 can be provided at one end of the transmission cable 600 for the fan 1000 to connect to an external power supply, so that when the fan 1000 is disassembled, the transmission cable 600 can be pulled out from the swing device 100, enabling the fan 1000 to achieve better disassembly and assembly, facilitating the overall storage and transportation of the fan 1000. At the same time, using the second terminal 117 to achieve the plug-in conduction with the transmission cable 600 is also beneficial for users to replace the adapter with a transmission cable 600 of a suitable length according to the actual usage environment, enabling the fan 1000 to better meet the usage requirements of users and further improving the practicability and reliability of the fan 1000.

[0074] Since in the actual use process of the fan 1000, the swing angle of the second connecting column 13 for swing ventilation is mostly set within 270°, usually it can be 90°, 120°, 150° or 180°, etc. At this time, the arc of the connecting rack 1191 in the connection groove 119 can be set corresponding to the rotation angle of the steering mechanism 15, so that the connecting rack 1191 can only occupy a part of the inner side wall of the connection groove 119. At this time, the second terminal 117 can be connected to the part of the inner side wall of the connection groove 119 where the connecting rack 1191 is not provided, so that the second terminal 117 and the connecting rack 1191 can be arranged at intervals on the inner side wall of the connection groove 119, preventing the connecting rotating rod 151 from interfering with the second terminal 117 and the wires when rotating in the connection groove 119. Among them, the wire groove 1111 can be arranged adjacent to one end of the second terminal 117 facing away from the wiring hole 115, so that the wires inside the fan 1000 can be more conveniently inserted into the wire groove 1111 for wiring after being connected to the second terminal 117, ensuring the wiring convenience inside the swing device 100. At the same time, it can well avoid the interference between the wires and the connecting rotating rod 151, further improving the structural stability and reliability of the swing device 100 and realizing a more compact structural design of the swing device 100.

[0075] The present utility model also provides a fan 1000, which includes a fan assembly 400, a support frame 200, and a swing device 100. The specific structure of the swing device 100 refers to the above-mentioned embodiments. Since this fan 1000 adopts all the technical solutions of the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated herein one by one.

[0076] Referring to Figure 6 and Figure 8 , in an embodiment of the present utility model, the support frame 200 includes a chassis 21 and a support column 23. The support column 23 is detachably connected to the swing device 100. A wire passing through hole 231 is provided in the support column 23, and the first wiring terminal 113 of the swing device 100 is exposed in the wire passing through hole 231. The fan 1000 further includes an adapter, and the adapter is provided with a transmission cable 600. The transmission cable 600 is movably arranged through the wire passing through hole 231. One end of the transmission cable 600 is provided with a third wiring terminal 61, and the third wiring terminal 61 is cooperatively connected with the first wiring terminal 113 of the swing device 100.

[0077] In this embodiment, the support frame 200 can be provided with an installation hole 111 on the bottom plate that cooperates with the support column 23 for insertion. At this time, a snap structure or a threaded structure, etc., can be respectively provided at one end of the support column 23 and the installation hole 111 of the chassis 21, so that the support column 23 and the chassis 21 can be detachably connected by snap fixation or threaded fixation, etc., improving the disassembly and assembly convenience of the support column 23 and the chassis 21; similarly, a snap structure or a threaded structure can be respectively provided at the other end of the support column 23 and the first mounting member 10 of the swing device 100, so that the support column 23 and the first mounting member 10 of the swing device 100 can be detachably connected by snap fixation or threaded fixation, improving the disassembly and assembly convenience of the support column 23 and the swing device 100. When the fan 1000 is stored, the components such as the support column 23, the chassis 21, the swing device 100, and the fan assembly 400 can be assembled and stored in a certain combination manner, or the multiple components of the fan 1000 can be respectively placed at the corresponding positions in a special storage mold for accommodation and storage, so as to reduce the volume of the fan 1000 during storage.

[0078] By arranging the support column 23 in a hollow columnar structure, a wire passing through hole 231 that penetrates both ends of the support column 23 can be formed inside the support column 23. Furthermore, when one end of the support column 23 is installed at the installation hole 111, the wire passing through hole 231 can be communicatively arranged through the installation hole 111. At this time, by arranging a first wiring terminal 113 at the end face of the first mounting member 10 of the swing device 100, the first wiring terminal 113 can be connected to a cable inside the swing device 100. When the first mounting member 10 is fixedly connected to the other end of the support column 23, the end face of the first mounting member 10 can be exposed inside the wire routing through hole of the support column 23. Therefore, the fan 1000 can electrically connect an adapter connected to an external power supply to the swing device 100 through the wire passing through hole 231, realizing the overall power supply and regulation of the fan 1000, etc. The adapter can be configured with a transmission cable 600 of a certain length. By arranging a third wiring terminal 61 at the end of the transmission cable 600 that is matingly inserted with the first wiring terminal 113, the adapter can pass the transmission cable 600 through the chassis 21, the wire outlet, and the wire passing through hole 231 and arrange it inside the support column 23, and enable the third wiring terminal 61 to be inserted into the first wiring terminal 113 of the swing device 100 inside the wire passing through hole 231, realizing the electrical connection between the adapter and the swing device 100, so that the fan 1000 can stably arrange the cable for transmitting power to the swing device 100 inside the support frame 200, which is beneficial to better avoid the external wiring cable of the fan 1000 being suspended and having a certain probability of tripping the user, reducing the interference of the fan 1000 with the user's activities, and at the same time making the overall structure of the fan 1000 more concise and improving the aesthetics of the fan 1000. Among them, the fan 1000 can arrange the installation hole 111 to penetrate the chassis 21. At this time, by using a foot pad to raise the chassis 21 so that there is a certain gap between the chassis 21 and the ground, the transmission cable 600 can enter the wire passing through hole 231 through the gap and the installation hole 111 to be electrically connected to the swing device 100; or a channel communicating with the installation hole 111 can be arranged in the chassis 21 so that the transmission cable 600 can enter the wire passing through hole 231 through the channel inside the chassis 21 and the installation hole 111, realizing the stable and reliable assembly of the transmission cable 600 on the support frame 200 and further improving the overall structural stability and reliability of the fan 1000.

[0079] By using the first terminal 113 and the third terminal 61 to connect the swing device 100 and the adapter, the swing device 100 and the transmission cable 600 can be detached more conveniently by plugging and unplugging. The support frame 200 is configured such that the widths of the wire passing through hole 231 and the mounting hole 111 are both larger than the outer diameter of the transmission cable 600, allowing the transmission cable 600 to move within a certain range when passing through the inside of the support frame 200. Therefore, when the fan 1000 needs to be disassembled and stored, after separating the swing device 100 from the support column 23 and pulling out a part of the transmission cable 600, the first terminal 113 and the third terminal 61 can be easily unplugged, completely separating the swing device 100 from the support frame 200 and the adapter. Then, the transmission cable 600 can be pulled out from the mounting hole 111 and the wire passing through hole 231, enabling the transmission cable 600 of the adapter to be easily detached from the swing device 100 and the support frame 200, avoiding interference of the electrical connection between the transmission cable 600 and the swing device 100 during the disassembly and storage of the fan 1000, ensuring the convenient disassembly and assembly of the fan 1000, and improving the practicality and reliability of the fan 1000. In addition, when the fan 1000 is assembled and used, the transmission cable 600 can be first passed through the mounting hole 111 and the wire passing through hole 231, then the support column 23 is connected and fixed at the mounting hole 111. After the third terminal 61 of the transmission cable 600 passes through the end of the support column 23 and is inserted into and mated with the first terminal 113 of the swing device 100, the first mounting member 10 of the swing device 100 is correspondingly mounted and fixed at the end of the support column 23 to achieve stable and reliable assembly of the fan 1000, enabling the transmission cable 600 to be stably and conveniently assembled inside the support frame 200, further improving the assembly convenience and reliability of the fan 1000.
