[0049] And by setting the second connecting hole 311 on the other connecting web plate 31, the end face of the first shaft section 511 facing away from the second shaft section 513 is provided with a flange, so that when the first shaft section 511 passes through the second connecting hole 311, the flange can abut against the side of the connecting web plate 31 facing away from the mounting seat 11, thereby ensuring the limited installation of the first shaft section 511 and the connecting web plate 31, and further ensuring the stable connection of the rotating shaft 50 and the swing piece 30 under the combined connection of the first shaft section 511 and the second shaft section 513 and the two connecting web plates 31, so that the swing piece 30 can be more stably swung up and down on the support structure 10 around the rotating shaft 50 under the driving of the driving device 70, thereby ensuring the stable operation of the swing device 100 and further improving the practicability and structural reliability of the swing device 100.

[0050] With reference to Figure 3 In an embodiment of the present application, the mounting seat 11 is provided with a first wire hole 115, and the connecting web plate 31 is provided with a second wire hole, and the first wire hole 115, the first wire port 5113, the wire passage 5111, the second wire port 5115 and the second wire hole are used for sequentially passing the connecting cable 500.

[0051] In the embodiment, the support structure 10 can be provided in a hollow structure to facilitate the arrangement of components inside the support structure 10. By providing the first wire hole 115 on the mounting base 11, the connection cable 500 can be routed from the inside of the support structure 10 through the first wire hole 115. It can be understood that the fan 1000 can be provided with a wire segment connected to an external power source around the outer periphery of the support structure 10, or an interface can be provided on the support structure 10, so that the wire segment connected to the external power source of the fan 1000 can be plugged into the interface on the support structure 10 through the joint, and the connection cable 500 can be electrically connected to the interface arranged in the swing device 100, thereby stably transmitting power and control signals to the fan 1000 and ensuring the stable operation of the fan 1000. Further, the connection cable 500 can pass through the first wire hole 115 of the support structure 10, bypass the mounting base 11, pass through the first wire port 5113, the wire passage 5111, and the second wire port 5115 of the shaft 50, and then pass through the second wire port 5115 to bypass the connecting web 31 and be connected to the fan assembly, thereby realizing stable routing of the connection cable 500 in the swing device 100, reducing interference or pulling of the connection cable 500 in the swing device 100, ensuring stable electrical connection between the connection cable 500 and the fan assembly, and further improving the structural stability and reliability of the swing device 100. By providing corresponding avoiding hole structures on the mounting base 11, the shaft 50, and the connecting web 31 for the connection cable 500 to pass through, the routing inside the swing device 100 can be more regular, and the cable can be better hidden inside the swing device 100, reducing the exposure of the cable, so that the swing device 100 can realize more beautiful structural design.

[0052] In some embodiments, the first wire port 5113 can be provided as a long strip port extending along the rotation direction around the shaft 50, so that the first wire port 5113 can have a larger length dimension, and when the swing piece 30 rotates relative to the support structure 10 in the up-down direction, the shaft 50 can rotate with the swing piece 30, thereby enabling the connection cable 500 to swing in the rotation direction at the first wire port 5113 with a larger length, which is beneficial to better reduce the pulling effect of the connection cable 500 when the shaft 50 and the swing piece 30 rotate, so that the connection cable 500 can be more stably and reliably routed in the swing device 100, preventing the connection cable 500 from being disconnected from the fan assembly, and further improving the practicality and structural reliability of the swing device 100.

[0053] Referring to Figure 3 and Figure 5In one embodiment of the utility model, the connecting web plate 31 is provided with a transmission rack 313 on the side facing the mounting base 11, the driving device 70 is a driving motor, the driving shaft of the driving device 70 is connected with a transmission gear 71, and the transmission gear 71 is in meshing connection with the transmission rack 313.

[0054] In the embodiment, the driving device 70 can be in the form of a driving motor, the driving motor can be fixedly installed on the mounting base 11, the transmission gear 71 can be arranged on the driving shaft of the driving motor, the transmission rack 313 can be arranged on the side of the connecting web plate 31 facing the mounting base 11, the transmission rack 313 can be provided with a plurality of clamping teeth matched with the transmission gear 71, the transmission rack 313 can be arranged in extension along the rotation direction of the rotating shaft 50, at this time, the transmission rack 313 can be arranged in the form of a ring-shaped rack or an arc-shaped rack around the rotating shaft 50, and when the driving device 70 drives the transmission gear 71 to rotate, the transmission gear 71 can be used to drive the transmission rack 313 and the connecting web plate 31 to rotate around the rotating shaft 50, so that the swinging device 100 can stably swing the swinging member 30 and the handpiece assembly 300. The swinging member 30 and the handpiece assembly 300 can be driven to swing in the up-down direction by the gear meshing action of the driving motor and the transmission rack 313, so that the structure of the driving device 70 in the swinging device 100 can be better simplified, the overall weight and volume of the swinging device 100 can be better reduced, the driving device 70 can drive the swinging member 30 to swing relative to the support structure 10 under lower working power, the stable swinging operation of the swinging device 100 can be ensured, and the practicability and reliability of the swinging device 100 can be further improved.

[0055] In one embodiment of the utility model, the mounting base 11 is provided with a first limiting structure, the connecting web plate 31 is provided with a second limiting structure, and the first limiting structure and the second limiting structure can be in abutting cooperation to limit the angle of rotation of the swinging member 30 relative to the support structure 10.

[0056] In the embodiment, the mounting seat 11 can be provided with a first limiting structure on the side facing the connecting web plate 31, and the connecting web plate 31 is provided with a second limiting structure on the side facing the mounting seat 11. The first limiting structure and the second limiting structure can be a boss structure, or can be a structure of a protrusion and a groove matched with each other. Of course, the first limiting structure and the second limiting structure can also adopt other structures matched with each other, and the application does not limit the structure form of the first limiting structure and the second limiting structure, as long as the first limiting structure and the second limiting structure can be matched and abutted when the connecting web plate 31 rotates relative to the mounting seat 11 by a certain angle. When the connecting web plate 31 rotates relative to the mounting seat 11 by a certain angle around the rotation shaft 50, the first limiting structure and the second limiting structure can abut against each other, thereby limiting the rotation angle of the connecting web plate 31, effectively preventing the second mounting member from rotating by too large an angle relative to the first mounting member, which has a certain probability of causing the components in the swing device 100 to collide with each other. For example, the transmission gear 71 of the driving device 70 can be prevented from colliding with the end of the transmission rack 313, or the swing member 30 can be prevented from colliding with the support structure 10, so that the swing device 100 can operate more stably and reliably.

[0057] In order to realize better swing angle of the fan 1000, the first limiting structure and the second limiting structure can abut against each other when the connecting web plate 31 rotates to drive the head assembly 300 to blow horizontally, and can abut against each other when the connecting web plate 31 rotates to drive the head assembly 300 to blow vertically upward, so that the swing device 100 can cover a larger blowing range. Of course, under the condition of meeting the mutual avoidance of the components of the swing device 100, the first limiting structure and the second limiting structure can abut against each other when the connecting web plate 31 rotates by a larger angle, so that the swing device 100 can better meet the use requirement, and the application does not limit the rotation range of the connecting web plate 31 limited by the first limiting structure and the second limiting structure.

[0058] Referring to Figure 4 and Figure 5 In an embodiment of the utility model, the mounting seat 11 is provided with a containing space, and the driving device 70 is arranged in the containing space, and the two ends of the driving device 70 abut against the opposite two side walls of the containing space.

At this time, when the connecting web plate 31 is arranged at the outer side wall of the mounting seat 11, a through hole communicating with the containing space can be arranged at the side wall of the mounting seat 11, so that the driving shaft of the driving device 70 can pass through the through hole, and the transmission gear 71 is located at the outer side wall of the mounting seat 11 and connected to the driving shaft of the driving device 70, so as to ensure the stable driving of the driving device 70 on the swing piece 30, and further improve the structural stability and reliability of the swing device 100.

[0060] In addition, by abutting the opposite two ends of the driving device 70 against the two opposite inner side walls of the containing space, the driving device 70 can be used to support the mounting seat 11, which is beneficial to avoid the deformation of the mounting seat 11 caused by the lateral force of the connecting web plate 31, and better ensure the stable operation of the swing device 100, and further improve the overall structural stability and reliability of the swing device 100.

[0061] Further, the width of the containing space of the mounting seat 11 can correspond to the thickness of the driving device 70, so as to ensure that the two ends of the driving motor can stably abut against the opposite two inner side walls of the containing space. Alternatively, the driving device 70 can include a motor body and a limiting block, the motor body is provided with a driving shaft connected to the transmission gear 71, one end face of the motor body abuts against one inner side wall of the containing space, and the limiting block is connected to the other end of the motor body, and the end of the limiting block opposite to the motor body abuts against the other opposite inner side wall of the containing space. By connecting the end of the motor body with the limiting block, the overall thickness of the driving motor can better correspond to the width of the containing space, which is beneficial to reduce the size requirement of the motor body and ensure the stable support of the driving device 70 on the mounting seat 11.

[0062] In an embodiment of the utility model, the support structure 10 includes a first connecting column, a second connecting column and a steering mechanism, the second connecting column is stacked with the first connecting column, and one end of the second connecting column opposite to the first connecting column is connected with the swing piece 30; the steering mechanism connects the first connecting column and the second connecting column, and drives the second connecting column to rotate relative to the first connecting column.

[0063] In the embodiment, the support structure 10 can be formed by the first connecting column and the second connecting column which are stacked with each other, the first connecting column and the second connecting column can be sleeve 113 structures with cavities, so that the steering mechanism can be installed in the inner cavities of the first connecting column and the second connecting column and connect the first connecting column and the second connecting column, by connecting and fixing the first connecting column with the support, the steering mechanism can be driven to work by electricity, so that the second connecting column is driven to rotate horizontally relative to the first connecting column, that is, the second connecting column can be rotated in the left-right direction. Further, by arranging the mounting seat 11 on the end of the second connecting column away from the first connecting column, the mounting seat 11 and the swing piece 30 can be driven to rotate together when the second connecting column rotates, the horizontal swing function of the swing device 100 is realized, so that the swing device 100 can realize a larger range of blowing effect, and the practicability and reliability of the swing device 100 are further improved. By arranging the steering mechanism in the support structure 10 to drive the second connecting column to rotate, and driving the second connecting column to drive the mounting seat 11 and the swing piece 30 to rotate horizontally, the swing device 100 can integrate the up-down swing function and the horizontal swing function, and further can realize the swing action of multiple degrees of freedom of the swing device 100, so that the fan 1000 can better meet the use requirements of the user, and the practicability and reliability of the swing device 100 are further improved. By integrating the horizontal head driving part on the support structure 10 of the swing device 100, and arranging the rotation shaft 50 and the driving device 70 between the support structure 10 and the swing piece 30 to realize the up-down head function, the swing device 100 can be more compactly arranged with multiple driving parts in a smaller volume, which is beneficial to better realize the miniaturization design of the swing device 100, and further can better reduce the overall volume of the swing device 100, and further improve the practicability of the swing device 100.
