[0038] The present invention provides a support structure 100 .

[0039] See also Figure 1 to Figure 2 In one embodiment of the present invention, the support structure 100 is used to support the housing 210, and the support structure 100 includes a support body 1, an oscillating head device 2 and a connecting arm 3; the oscillating head device 2 connects the support body 1 and the connecting arm 3, and the connecting arm 3 is bent at one end facing away from the oscillating head device 2 and connected to the housing 210. The oscillating head device 2 can drive the connecting arm 3 and the housing 210 to swing up and down and rotate left and right.

[0040] It can be understood that blowing devices 1000 such as fans and heaters have a housing 210 that protects the fan or impeller 260. In this embodiment, the swing device 2 and the housing 210 are connected by a connecting arm 3 to drive the housing 210 to swing, thereby expanding the blowing area. The connecting arm 3 adopts a 7-shaped cantilever structure. One end of the connecting arm 3 is connected to the swing device 2 to achieve the fixation and transmission of the connecting arm 3. In this embodiment, considering the convenience of disassembly, assembly, and maintenance, the connecting arm 3 and the swing device 2 are set to be detachably connected, for example, by bolts, snap-fit structures, etc. The other end of the connecting arm 3 is connected to the housing 210 of the blowing device 1000 for installing and fixing the housing 210. Similarly, considering the convenience of disassembly, assembly, and maintenance, the connecting arm 3 and the housing 210 are set to be detachably connected, for example, by bolts, snap-fit structures, etc. The housing 210 is arranged below the cantilever of the connecting arm 3, that is, the connecting arm 3 is connected to the top of the housing 210. The advantage of this setting is that the force on the connecting arm 3 is optimized, and there is no need to use large-sized connecting parts and support parts on the housing 210 to connect the housing 210 and the connecting arm 3, reducing the structural size. Since the housing 210 is lower than the connecting arm 3, the center of gravity of the entire blowing device 1000 is lowered, improving the stability of the bracket. In addition, in the traditional method, an installation structure 250 is provided at the center of the housing 210 for connecting to the swing device 2. The traditional connection method requires the swing device 2 to pass through the air inlet grille 230 before connecting to the installation structure 250 at the center of the housing 210, making the disassembly and assembly of the air inlet grille 230 inconvenient. Compared with the traditional connection method, in this embodiment, the swing device 2 is connected to the side wall of the housing 210 through the connecting arm 3, and the air inlet grille and the air outlet grille on the housing 210 can be independently disassembled, facilitating cleaning and maintenance. It should be noted that the connecting arm 3 can also be connected to the bottom or side of the housing 210, and the air inlet grille and the air outlet grille on the housing 210 can still be independently disassembled. It should also be noted that the connecting arm 3 can also adopt shapes such as C-shaped and U-shaped to achieve connection with the side wall of the housing 210.

[0041] The swing device 2 integrates the mechanisms for realizing the two functions of up-and-down swing and left-and-right swing. The bottom wall of the swing device 2 is connected to the bracket main body 1, and the top of the swing device 2 is connected to the connecting arm 3. The swing device 2 can drive the connecting arm 3 and the housing 210 to swing up and down and rotate left and right. The bracket main body 1 can adopt structures such as a column, a tripod, a suction cup, or a clip to adapt to usage scenarios such as the ground or the wall surface. For the convenience of disassembly, assembly, and maintenance, the swing device 2 can be detachably connected to the bracket main body 1 by means of threads, screws, and snap-fit structures, etc.

[0042] The support structure 100 of this embodiment integrates the left and right shaking mechanism and the up and down shaking mechanism into one, that is, through one shaking device 2, it can realize both left and right shaking and up and down shaking, thereby reducing the volume of the shaking device 2. The shaking device 2 drives the connecting arm 3 and the housing 210 to shake up and down or left and right. In addition, the connecting arm 3 is connected to the side wall of the housing 210, avoiding the connection between the connecting arm 3 and the housing 210 through a large-sized connecting structure. In this way, the simple and compact design of the hair dryer 1000 is achieved, and the practicality and reliability of the support structure 100 are improved.

[0043] For further information, see Figure 1 and Figure 7 In one embodiment of the present invention, the connecting arm 3 includes a first connecting portion 31 and a second connecting portion 32. The first connecting portion 31 is spaced apart from the air inlet end of the casing 210 and is connected to the shaking head device 2. The second connecting portion 32 is bent and connected to the first connecting portion 31 and is connected to the side wall of the casing 210.

[0044] In this embodiment, the first connection part 31 is located at the end of the connecting arm 3 close to the oscillating device 2. The first connection part 31 is provided with a bolt hole for connecting and fixing with the oscillating device 2. The first connection part 31 is provided with an arc groove to adapt to the outer contour shape of the oscillating device 2, so as to facilitate the swing of the connecting arm 3 relative to the oscillating device 2. The second connection part 32 is located at the end of the connecting arm 3 away from the oscillating device 2. The second connection part 32 is provided with a plurality of pivots, and the center of the pivot is provided with a bolt hole for achieving installation and fixing with the housing 210. A gap is formed between the first connection part 31 and the air inlet end of the housing 210 to prevent the connecting arm 3 from blocking the air inlet end of the housing 210, thereby ensuring the air intake of the housing 210, reducing turbulence, and ensuring stable air intake of the housing 210.

[0045] The connecting arm 3 can adopt a hollow structure while ensuring the supporting strength. The hollow inside the connecting arm 3 can be used to set the connecting wires of the motor, etc. The second connecting part 32 and the casing 210 are provided with two interconnected wiring openings to allow the connecting wires to pass through the connecting arm 3 and enter the casing 210.

[0046] For further information, see Figure 1 and Figure 7 In one embodiment of the present invention, the connecting arm 3 includes two second connecting portions 32, and the two second connecting portions 32 are respectively connected to opposite sides of the housing 210; or, the bracket structure 100 includes two connecting arms 3, and the two connecting arms 3 are respectively connected to opposite sides of the housing 210.

[0047] In this embodiment, the connecting arm 3 includes two second connecting parts 32, and the two second connecting parts 32 are respectively connected to the opposite sides of the housing 210. The bracket has two ends away from the first connecting part 31, and the two ends are respectively provided with second connecting parts 32, and the two ends are respectively connected to the opposite sides of the housing 210 through the second connecting parts 32. In this way, the connection strength between the shaking head device 2 and the housing 210 is strengthened, which is conducive to the stable support of the hair dryer 1000. Or, the bracket structure 100 includes two connecting arms 3, and the two connecting arms 3 are respectively connected to the opposite sides of the housing 210, that is, the two connecting arms 3 can also be a split design, and the two connecting arms 3 are both connected to the shaking head device 2, and the two connecting arms 3 are respectively connected to the side of the housing 210. This split design not only strengthens the connection strength between the shaking head device 2 and the housing 210, but also facilitates flexible disassembly and assembly.

[0048] For further information, see Figure 3 and Figure 4 In one embodiment of the present invention, the shaking head device 2 includes a first connecting structure 21, a second connecting structure 22, a swinging device 23 and an elastic member 24, the first connecting structure 21 is connected to the bracket body 1; the second connecting structure 22 is connected to the connecting arm 3, and the second connecting structure 22 is hinged to the first connecting structure 21; the swinging device 23 connects the first connecting structure 21 and the second connecting structure 22, and drives the second connecting structure 22 to swing relative to the first connecting structure 21; the elastic member 24 connects the first connecting structure 21 and the second connecting structure 22.

[0049] In this embodiment, the shaking head device 2 may include a first connecting structure 21 and a second connecting structure 22. The first connecting structure 21 may be a column structure connected to the supporting frame, and the second connecting structure 22 may be a frame structure connected and fixed to the fan and / or the casing 210. After the first connecting structure 21 is connected to the second connecting structure 22, the casing 210 can be installed on the vertical supporting frame through the shaking head device 2 to maintain horizontal blowing, thereby ensuring the stable operation of the blowing equipment 1000.

[0050] By setting a swinging device 23 between the first connecting structure 21 and the second connecting structure 22, the swinging device 23 connects the first connecting structure 21 and the second connecting structure 22. The swinging device 23 can be used to connect and drive the second connecting structure 22 to rotate relative to the first connecting structure 21, so that the second connecting structure 22 can be swung toward the first connecting structure 21 or away from the first connecting structure 21 in the height direction of the blowing device 1000. Furthermore, under the driving action of the swinging device 23, the second connecting structure 22 can drive the casing 210 to swing up and down in the height direction of the blowing device 1000, thereby realizing the up and down swinging sweeping function of the blowing device 1000 and effectively expanding the blowing range of the blowing device 1000.

[0051] By connecting the first connection structure 21 and the second connection structure 22 with an elastic member 24, the elastic member 24 may be a spring, a torsion spring or a leaf spring. When the hair-drying device 1000 is in a horizontal blowing state, the elastic force exerted by the elastic member 24 on the second connection structure 22 can completely or partially offset the gravity of the housing 210 and the fan etc. borne on the second connection structure 22, thereby reducing the power consumption generated by the shaking device 2 to maintain the horizontal blowing of the hair-drying device 1000. When the hair-drying device 1000 is in a state of blowing diagonally downward, the gravity of the housing 210 and the second connection structure 22 acts on the elastic member 24, causing the elastic member 24 to undergo a certain elastic deformation. At this time, the swing device 23 is continued to be used to play a certain limiting self-locking role on the relative rotation of the first connection structure 21 and the second connection structure 22, so as to overcome the elastic force of the elastic member 24 and enable the elastic member 24 to maintain the elastic deformation occurring at this time. In this way, the hair-drying device 1000 is guaranteed to perform stable horizontal blowing or diagonally downward blowing.

[0052] When the swing device 23 drives the second connecting structure 22 to swing relative to the first connecting structure 21, at this time, as the second connecting structure 22 swings upward, the elastic member 24 can restore a certain elastic deformation to apply a force to the second connecting structure 22 and the casing 210, so that part of the elastic force applied by the elastic member 24 on the second connecting structure 22 and part of the gravity of the casing 210 on the second connecting structure 22 offset each other, and thus the elastic member 24 can play a certain auxiliary role when the swing device 23 drives the second connecting structure 22 to lift and rotate, so that the swing device 23 can drive the second connecting structure 22 to swing smoothly with lower power consumption, and the swing device 23 can adopt a smaller low-power driving device, thereby realizing the miniaturized design of the shaking head device 2, effectively reducing the overall volume of the hair-drying device 1000, and improving the practicality and reliability of the shaking head device 2.

[0053] For further information, see Figure 3 and Figure 4 In one embodiment of the present invention, the first connecting structure 21 is provided with a mounting seat 214, the second connecting structure 22 is provided with a connecting web 222, and the swing device 23 transmission connects the mounting seat 214 and the connecting web 222; a first mounting protrusion 2141 is provided on one side of the mounting seat 214, and a second mounting protrusion 2221 is provided on one side of the connecting web 222, and both ends of the elastic member 24 are respectively connected to the first mounting protrusion 2141 and the second mounting protrusion 2221.

[0054] In this embodiment, the first connection structure 21 may be provided with a mounting seat 214 protruding on its end face. The mounting seat 214 may be a sheet metal structure with a certain structural strength erected on the end face of the first connection structure 21, or may be a block structure with a certain volume thickness, etc. At this time, the second connection structure 22 may be provided with a connecting web 222 protruding on the side close to the first connection structure 21. The connecting web 222 may be a sheet metal with a certain structural strength, and the connecting web 222 may be correspondingly arranged on the outer side wall of the mounting seat 214, or the connecting web 222 may be correspondingly arranged on the inner side wall of the mounting seat 214. For example, both the mounting seat 214 and the second connection structure 22 are provided as U-shaped sheet metal structures. The mounting seat 214 has two parallel wall bodies. The second connecting member includes a mounting plate 221 and two parallel connecting webs 222. The two parallel connecting webs 222 are arranged on the opposite sides of the mounting plate 221 and are located outside the two parallel wall bodies of the mounting seat 214, and the connecting web 222 is hinged to the wall body of the mounting seat 214. Furthermore, the swinging device 23 may be arranged between the connecting web 222 and the mounting seat 214, and the swinging device 23 is used to drive the connecting web 222 to swing relative to the mounting seat 214, realizing the swinging design of the second connection structure 22 relative to the first connection structure 21 in the up and down directions, and ensuring the stable operation of the head shaking mechanism.

[0055] By providing a first mounting protrusion 2141 on one side of the mounting seat 214 and a second mounting protrusion 2221 on one side of the connecting web 222, the first mounting protrusion 2141 and the second mounting protrusion 2221 may be arranged opposite to each other in the up and down directions, so that both ends of the elastic member 24 can be connected to the first mounting protrusion 2141 and the second mounting protrusion 2221, realizing the connection of the elastic member 24 between the first connection structure 21 and the second connection structure 22, enabling the elastic member 24 to stably pull the second connection structure 22 when the swinging device 23 drives the second connection structure 22 to rise relative to the first connection structure 21, and reducing the load acting on the swinging device 23. By using the first mounting protrusion 2141 and the second mounting protrusion 2221 to connect and mount the elastic member 24, the elastic member 24 can be better arranged to avoid the swinging device 23, realizing a more reasonable and compact spatial layout of the head shaking mechanism, and at the same time facilitating the maintenance and replacement of the elastic member 24, further improving the practicality and structural reliability of the head shaking mechanism. It should be noted that the first mounting protrusion 2141 may be arranged to be detachably connected to the mounting seat 214, and the second mounting protrusion 2221 may be arranged to be detachably connected to the connecting web 222. Taking the second mounting protrusion 2221 as an example, screw holes may be provided on the connecting web 222, and the second protrusion may be mounted on the connecting web 222 through bolts. Figure 3 and Figure 4An exploded view is used for convenience of observation. In the exploded view, the second mounting protrusion 2221 is separated from the connecting web 222 . It can be understood that the second mounting protrusion 2221 in the figure can be connected to the connecting web 222 .

[0056] The connecting web 222 and the mounting seat 214 are respectively provided with limit members to limit the range of rotation of the connecting web 222 relative to the mounting seat 214 to prevent the structure from being easily damaged due to excessive rotation angle, and the position of the limit members can be set so that when the two limit members are in contact, the orientation of the hair dryer 1000 just reaches a specific angle to meet the user's usage requirements, such as the air outlet of the hair dryer 1000 just faces upwards, such as Fig. 9 As shown, at this time, the limiting member can enable the blowing device 1000 to blow air upward stably without the need for the shaking head device 2 to generate additional power consumption to limit the direction, thereby saving energy consumption.

[0057] See also Figure 3 and Figure 4 In one embodiment of the present invention, the shaking device 2 also includes a connecting shaft 25, the connecting shaft 25 includes a bearing structure 252 and a shaft body 251, the shaft body 251 passes through the mounting seat 214 and the connecting web 222, the bearing structure 252 is connected to the mounting seat 214 and / or the connecting web 222, and the bearing structure 252 is sleeved on the outer periphery of the shaft body 251; the swinging device 23 is connected to the mounting seat 214 or the second connecting structure 22, and the swinging device 23 drives the connecting web 222 to swing around the central axis of the connecting shaft 25 relative to the mounting seat 214.

[0058] In this embodiment, the swing device 23 can use the connecting shaft 25 to pass through the mounting seat 214 and the connecting web 222, and connect the mounting seat 214 and the connecting web 222, so that the connecting web 222 can rotate around the axial direction of the connecting shaft 25 under the action of the connecting shaft 25. At this time, the swing device 23 can be connected and installed on the mounting seat 214, and the swing device 23 is transmission-connected with the second connecting structure 22; or, the swing device 23 can be connected and installed on the second connecting structure 22, and the swing device 23 is transmission-connected with the mounting seat 214. The swing device 23 can be a matching structure of a motor and a gear transmission, or a structure of a telescopic push rod, etc., so that under the action of the swing device 23 and the connecting shaft 25, the second connecting structure 22 can be stably driven to swing relative to the mounting seat 214 around the central axis of the connecting shaft 25, so as to realize the up and down wind swinging function of the fan, and further improve the structural stability and reliability of the shaking mechanism.

[0059] It can be understood that the connecting shaft 25 can include a shaft body 251 that passes through the mounting seat 214 and the connecting web 222, and a bearing structure 252 that is sleeved on the outer periphery of the shaft body 251. Under the action of the bearing structure 252, a smoother rotation effect of the shaft body 251 can be achieved, and the friction of the shaft body 251 during rotation can be reduced. Furthermore, a through hole can be set on the side wall of the mounting seat 214, so that the bearing structure 252 is installed and fixed in the through hole, so that the shaft body 251 can pass through the bearing structure 252 on the mounting seat 214 and connect with the connecting web 222; or, a through hole can be set on the side wall of the connecting web 222, so that the bearing structure 252 is installed and fixed in the through hole, and the mounting seat 214 is provided with relative bearing holes, so that the shaft body 251 can pass through the bearing structure 252 and the bearing hole to connect the mounting seat 214 and the connecting web 222; or, the bearing structure 252 can be set on both the mounting seat 214 and the connecting web 222, so that the shaft body 251 can be successively passed through the bearing structures 252 of the mounting seat 214 and the connecting web 222. By utilizing the matching design of the bearing structure 252 and the shaft body 251, the friction force between the connecting shaft 25 and the support and swinging parts can be effectively reduced, which is beneficial to better reduce the load on the driving device, so that the driving component can better adopt a smaller power driving device setting, further improving the practicality and reliability of the shaking head device 2.

[0060] In addition, when the mounting seat 214 or the connecting web 222 is set up using a sheet metal structure, the bearing structure 252 can also include a bearing seat and a bearing body. The bearing seat can be clamped and installed on the mounting seat 214 or the connecting web 222, and the bearing body can be installed and fixed in the bearing seat, so that the bearing structure 252 can be more stably and reliably connected and installed on the mounting seat 214 or the connecting web 222, avoiding a certain probability of the bearing not being properly installed due to the thickness of the mounting seat 214 or the connecting web 222 being too small. There is no need for the mounting seat 214 and the connecting web 222 to adopt a more complex structural design to increase production costs, thereby further improving the practicality and structural reliability of the shaking head device 2.

[0061] For further information, see Figure 3 and Figure 4 In one embodiment of the present invention, the swing device 23 includes a first drive motor 231 and a transmission structure 233. The first drive motor 231 is arranged on the mounting seat 214, and the first drive motor 231 is provided with a first drive gear 232; the transmission structure 233 is connected to the connecting web 222, and the transmission structure 233 is provided with a first rack 2331. The first rack 2331 is extended along the circumference of the shaft body 251, and the first rack 2331 is meshed with the first drive gear 232.

[0062] In this embodiment, the first drive motor 231 in the swing device 23 is installed and fixed on the mounting seat 214, and the first drive gear 232 can be set on the rotating shaft of the first drive motor 231. By setting a transmission structure 233 on the side of the connecting web 222 facing the first drive motor 231, the transmission structure 233 can be a first rack 2331 structure set on the plate surface of the connecting web 222, and the first rack 2331 can be provided with a plurality of locking teeth that cooperate with the first drive gear 232, and the first rack 2331 can be set in an arc-shaped structure with an arc equal to the swing path of the second mounting part, that is, the first rack 2331 is extended along the circumferential direction of the shaft body 251, so that when the first drive motor 231 drives the first drive gear 232 to rotate, the first drive gear 232 can be used to engage and drive the first rack 2331 and the connecting web 222 to rotate around the connecting shaft 25, thereby realizing the stable swinging operation of the shaking device 2. In this way, the structural setting of the swing device 23 on the connecting web 222 can be better simplified, which is conducive to better reducing the overall weight of the connecting web 222, so that the swing device 23 can drive the connecting web 222 to swing relative to the support member under lower working power, thereby ensuring the stable swinging operation of the fan and further improving the practicality and reliability of the shaking device 2.

[0063] For further information, see Figures 5 to 7 In one embodiment of the present invention, the first connecting structure 21 includes a first pillar 211, a second pillar 212 and a steering device 213.

[0064] In this embodiment, the first mounting member may be formed by a first support 211 and a second support 212 stacked on each other, and the first support 211 and the second support 212 may be sleeve structures with a certain cavity, so that the steering device 213 may be installed in the inner cavity of the first support 211 and the second support 212, and connect the first support 211 and the second support 212. By connecting and fixing the first support 211 to the support frame, the steering device 213 may be operated by electrically driving the steering device 213, so that the steering device 213 drives the second support 212 to rotate in the horizontal direction relative to the first support 211. Furthermore, by connecting the end of the second support 212 facing away from the first support 211 with the swing mechanism and the second mounting member, the second mounting member may be driven to rotate together when the second support 212 rotates horizontally, thereby realizing the horizontal swing function of the fan, so that the fan can achieve a wider range of blowing effects, and further improving the practicality and reliability of the shaking device 2. By providing a steering device 213 in the first mounting part to drive the second support 212 to rotate, and by allowing the second support 212 to drive the second mounting part to rotate horizontally, the shaking device 2 can integrate the up and down swinging function and the horizontal swinging function, thereby enabling the shaking device 2 to achieve a swinging effect with multiple degrees of freedom, effectively improving the blowing range of the fan, so that the fan can better meet the user's usage needs, and further improving the practicality and reliability of the shaking device 2. By integrating a horizontal shaking drive component on the first mounting part of the shaking device 2, and providing a swing mechanism between the first mounting part and the second mounting part to achieve the up and down shaking function, the shaking device 2 can arrange multiple driving components more compactly within a smaller volume setting, which is conducive to better realizing the miniaturization design of the shaking device 2, thereby better reducing the overall volume of the fan, and further improving the practicality of the shaking device 2.

By arranging a bearing on the outside of the shaft body 251 to reduce the friction between the first pillar 211 and the rotating shaft 2121, the smoothness of the sliding of the second pillar 212 relative to the first pillar 211 is improved.

[0067] A second rack 2133 extending along the axial direction of the rotating shaft 2121 is arranged on the inner wall of the shaft hole 211a, and the second pillar 212 is hollow to form a cavity for accommodating the second driving motor 2131. An opening is arranged on the inner wall of the cavity to accommodate the second driving gear 2132. The second driving gear 2132 is connected to the shaft of the second driving motor 2131 and passes through the opening to mesh with the second rack 2133. When the second driving motor 2131 drives the second driving gear 2132 to move along the second rack 2133, the second pillar 212 is driven to rotate relative to the first pillar 211 around the axial direction of the rotating shaft 2121, so that the shaking device 2 drives the housing 210 to shake left and right to sweep the wind.
