[0033] In the application, the support structure 10 can include but is not limited to a stand, a triangular support, a clamping structure and the like, and the support structure 10 is used to realize the overall support of the fan device 100, so that the fan device 100 can be stably placed in various environments for blowing operation, and the stable operation of the fan device 100 is ensured.

[0034] The head assembly 30 can generally include a fan, a fan blade, and a fan blade cover or a fan outlet tube, so that the head assembly 30 can drive the fan blade to generate a blowing air flow by using the fan, thereby realizing the blowing operation of the fan device 100. At this time, the head assembly 30 can be provided with a support web 31 on the back side of the fan, or can be provided with a support web 31 on the side or back side of the fan outlet tube of the head assembly 30, of course, the support web 31 can also be provided on the back side of the head assembly 30 of other structures. The present application does not limit the structure of the head assembly 30 and the support web 31, as long as it can guarantee the stable blowing of the head assembly 30 and the stable support of the support web 31 to the head assembly 30.

[0035] By arranging the support web 31 on one side of the mounting seat 11 at the top of the support structure 10, arranging the mounting seat 11 with a first connecting hole 1131, and arranging the support web 31 with a second connecting hole 3131, the connecting shaft 51 can pass through the first connecting hole 1131 and the second connecting hole 3131 to realize the connection of the support web 31 and the mounting seat 11, and then the head assembly 30 is stably mounted on the support structure 10. At this time, by arranging a bearing 53 in the first connecting hole 1131 of the mounting seat 11 or in the second connecting hole 3131 of the support web 31, the bearing 53 can include an outer ring, an inner ring, and bearing 53 balls arranged between the outer ring and the inner ring, so that the bearing 53 can tightly connect the outer ring with the inner wall of the first connecting hole 1131 or the second connecting hole 3131, and the connecting shaft 51 can be sleeved in the inner ring of the bearing 53, so that the connecting shaft 51 can rotate more smoothly under the action of the bearing 53. Further, by connecting a stop ring 55 at the end of the connecting shaft 51 passing through the support web 31, and using the stop ring 55 to abut against the side wall of the support web 31 facing away from the mounting seat 11, the shaft structure 50 can stably connect the mounting seat 11 and the support web 31, effectively preventing the connecting shaft 51 from being separated from the mounting seat 11 and the support web 31 in the axial direction, so that the rotation of the connecting shaft 51 can be used to rotate the support web 31 relative to the mounting seat 11 around the connecting shaft 51. It should be noted that the head assembly 30 can be provided with a support web 31 on opposite sides of the mounting seat 11, so that the connecting shaft 51 can pass through the two support webs 31 and the mounting seat 11, and the stop ring 55 can be connected at both ends of the connecting shaft 51, and the two stop rings 55 can abut against the two support webs 31 respectively, so that the shaft structure 50 can be more stably connected between the support structure 10 and the head assembly 30, effectively improving the structural stability and reliability of the fan device 100.

[0036] And by connecting the driving member 70 on the mounting base 11 or the support web 31, the driving member 70 can adopt a driving device such as a motor, and can make the driving member 70 connected with the support web 31 through a gear transmission structure; or can make the driving member 70 drive the connecting shaft 51 to rotate, and drive the support web 31 to rotate through the connecting shaft 51, so that under the driving action of the driving member 70, the support web 31 can be driven to rotate around the central axis of the connecting shaft 51, and then the support web 31 and the head assembly 30 can be swingably arranged on the mounting base 11 in the up-down direction, realizing the up-down swing operation of the fan device 100, effectively increasing the blowing range of the fan device 100, and improving the practicability and reliability of the fan device 100.

[0037] In addition, by connecting the mounting base 11 and the support web 31 through the elastic member 90, the elastic member 90 can include but is not limited to a tension spring, a spring, a torsional spring, or a spring leaf, etc. When the support web 31 and the head assembly 30 swing relative to the mounting base 11, the elastic member 90 can be elastically deformed. Therefore, when the head assembly 30 swings along the up-down direction to blow in the horizontal direction, the elastic member 90 can be elastically deformed between the support web 31 and the mounting base 11. Then, when the support web 31 and the head assembly 30 swing upward relative to the mounting base 11, the elastic member 90 can be in a state of recovering the elastic deformation, so that the support web 31 can be subjected to a certain upward elastic force of the elastic member 90. Then, the elastic force of the elastic member 90 can overcome part of the gravity of the head assembly 30, so that the driving member 70 can drive the support web 31 and the head assembly 30 to swing upward by using smaller power. Therefore, the driving member 70 can be designed in a smaller size, which is beneficial to better reduce the overall structure size of the fan device 100, and realize the miniaturization design of the fan device 100.

[0038] And by making the rotating shaft structure 50 stably arrange the connecting shaft 51 between the mounting base 11 and the support web 31 through the bearing 53 and the retainer 55, the support web 31 can swing along the up-down direction under the more smooth rotating action of the connecting shaft 51, which can be beneficial to better reduce the resistance of the head assembly 30 relative to the support structure 10, i.e. to better reduce the rotating friction resistance of the rotating shaft structure 50, so that the fan device 100 can more stably and reliably drive the support web 31 and the head assembly 30 to swing along the up-down direction through the cooperation of the driving member 70 and the elastic member 90, and better reduce the power demand of the driving member 70. At the same time, the loosening of the connecting shaft 51 between the head assembly 30 and the support structure 10 can be effectively prevented, which is beneficial to better reduce the wear of the rotating shaft structure 50 and the noise generated during the operation of the fan device 100, and further improves the structural stability and reliability of the fan device 100.

In addition, the mounting structure 313 forms the second connecting hole 3131, which can make the blocking ring 55 abut against the side wall of the mounting structure 313 away from the mounting seat 11.

[0053] Referring to Figure 4 In an embodiment of the present application, the side of the mounting seat 11 opposite to the head assembly 30 is provided with a first protrusion 1111, and one end of the support web 31 opposite to the head assembly 30 is provided with a second protrusion 3111; the elastic member 90 is arranged on the side of the mounting seat 11 opposite to the head assembly 30 and extends in the up-down direction, and the two ends of the elastic member 90 are respectively connected to the first protrusion 1111 and the second protrusion 3111.

[0054] By arranging the first protrusion 1111 on one side of the mounting seat 11 and the second protrusion 3111 on one side of the support web 31, the first protrusion 1111 and the second protrusion 3111 can be arranged opposite to each other in the up-down direction, so that the two ends of the elastic member 90 can be connected to the first protrusion 1111 and the second protrusion 3111, realizing the connection and support of the elastic member 90 to the mounting seat 11 and the support web 31, so that the elastic member 90 can stably pull and support the support web 31 when the driving member 70 drives the support web 31 to rise relative to the mounting seat 11, reducing the load acting on the driving member 70. By connecting the elastic member 90 by the first protrusion 1111 and the second protrusion 3111, the elastic member 90 can better avoid the components arranged between the mounting seat 11 and the support web 31, realize a more reasonable and compact space layout of the fan device 100, facilitate the maintenance and replacement of the elastic member 90, and further improve the practicability and structural reliability of the fan device 100.

[0055] In an embodiment of the utility model, the mounting seat 11 is provided with a first limiting structure, the support web plate 31 is provided with a second limiting structure, the first limiting structure and the second limiting structure can cooperate and abut to limit the rotation angle of the support web plate 31 relative to the mounting seat 11.

[0056] In the embodiment, the mounting seat 11 can be provided with the first limiting structure on the side facing the support web plate 31, and the second limiting structure on the side of the support web plate 31 facing the mounting seat 11. The first limiting structure and the second limiting structure can be a boss structure, or a mutually cooperating protrusion and groove structure. Of course, the first limiting structure and the second limiting structure can also be provided with other structures for cooperating and abutting. 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 cooperate and abut when the support web plate 31 rotates a certain angle relative to the mounting seat 11. When the support web plate 31 rotates a certain angle relative to the mounting seat 11 around the connecting shaft 51, the first limiting structure and the second limiting structure can abut each other, thereby limiting the rotation angle of the support web plate 31. This effectively prevents the second mounting member from rotating too large an angle relative to the first mounting member, which may, with a certain probability, cause the components in the fan device 100 to collide with each other. For example, it can prevent the transmission gear 75 of the driving member 70 from colliding with the end of the transmission rack 3135, or it can prevent the head assembly 30 from colliding with the support structure 10, etc., so that the fan device 100 can operate more stably and reliably.

[0057] In order to achieve better swing angle of the fan, the first limiting structure and the second limiting structure can abut each other when the support web plate 31 rotates to drive the head assembly 30 to blow horizontally, and can abut each other when the support web plate 31 rotates to drive the head assembly 30 to blow vertically upward, so that the fan device 100 can cover a larger blowing range. Of course, under the condition of meeting the mutual avoidance of various components of the fan device 100, the first limiting structure and the second limiting structure can abut each other when the support web plate 31 rotates a larger angle, so that the fan device 100 can better meet the use requirements. The application does not limit the rotation range of the support web plate 31 limited by the first limiting structure and the second limiting structure.

[0058] 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 the end of the second connecting column opposite to the first connecting column is provided with the mounting seat 11. 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.

[0059] 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 and can be sleeve 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 operate 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 which is opposite to the first connecting column, the head assembly 30 can be driven to rotate together with the second connecting column when the second connecting column rotates, so as to realize the horizontal swing function of the fan device 100, so that the fan device 100 can realize a larger blowing effect, and further improve the practicability and reliability of the fan device 100. 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 rotate horizontally, the fan 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, so as to make the fan better meet the use demand of the user, and further improve the practicability and reliability of the fan device 100. By integrating the horizontal head driving part on the support structure 10 of the fan device 100, and arranging the driving part 70 between the support structure 10 and the head assembly 30 to realize the up-down head function, the fan device 100 can more compactly arrange multiple driving parts in a smaller volume, which is beneficial to better realize the miniaturization design of the fan device 100, and further can better reduce the overall volume of the fan device 100, and further improve the practicability of the fan device 100.
