[0038] This utility model proposes a support structure 100.

[0039] Please see Figures 1-2 In one embodiment of the present invention, the bracket structure 100 is used to support the housing 210. The bracket structure 100 includes a bracket body 1, a swaying device 2, and a connecting arm 3. The swaying device 2 connects the bracket body 1 and the connecting arm 3. The end of the connecting arm 3 facing away from the swaying device 2 is bent and connected to the housing 210. The swaying 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 the blowing device 1000 such as a fan, a hair dryer, etc. has a casing 210 for protecting the fan or the fan blade 260. In the embodiment, the casing 210 is connected to the swing head device 2 through the connecting arm 3 to drive the casing 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 head device 2 to realize the fixation and transmission of the connecting arm 3. In the embodiment, the connecting arm 3 and the swing head device 2 are detachably connected, for example, through bolts, clamping structures, etc. The other end of the connecting arm 3 is connected to the casing 210 of the blowing device 1000 to realize the fixation of the casing 210. Similarly, the connecting arm 3 and the casing 210 are detachably connected, for example, through bolts, clamping structures, etc. The casing 210 is arranged below the cantilever of the connecting arm 3, that is, the top of the connecting arm 3 is connected to the casing 210. This arrangement has the advantages of optimizing the stress of the connecting arm 3 and reducing the structure size without using large-size connecting members and supporting members to connect the casing 210 and the connecting arm 3. Since the casing 210 is lower than the connecting arm 3, the center of gravity of the whole blowing device 1000 is lowered, thereby improving the stability of the support. In addition, in the traditional method, the center of the casing 210 is provided with an installation structure 250 to be connected to the swing head device 2. The traditional connection mode requires the swing head device 2 to pass through the air inlet grille 230 to be connected to the installation structure 250 at the center of the casing 210, which is not convenient for disassembly. Compared with the traditional connection mode, the connecting arm 3 is used to connect the swing head device 2 to the side wall of the casing 210 in the embodiment, and the air inlet grille and the air outlet grille on the casing 210 can be independently disassembled, which is convenient for cleaning and maintenance. It should be noted that the connecting arm 3 can also be connected to the bottom or the side of the casing 210, which can also realize that the air inlet grille and the air outlet grille on the casing 210 can be independently disassembled. It should be further noted that the connecting arm 3 can also adopt a C-shaped or a U-shaped shape to be connected to the side wall of the casing 210.

[0041] The swing head device 2 integrates the mechanisms for realizing the up-down and left-right swinging functions. The bottom wall of the swing head device 2 is connected to the support body 1, and the top of the swing head device 2 is connected to the connecting arm 3. The swing head device 2 can drive the connecting arm 3 and the casing 210 to swing up-down and rotate left-right. The support body 1 can adopt a stand, a tripod, a suction cup or a clamp, etc. to adapt to the use scenarios on the ground or the wall, etc. In order to facilitate disassembly and maintenance, the swing head device 2 can be detachably connected to the support body 1 through threads, screws, clamping structures, etc.

[0042] The support structure 100 of the embodiment can realize left and right tilting and up and down tilting through the integration of the left and right tilting mechanism and the up and down tilting mechanism, i.e. through one tilting device 2, thereby reducing the size of the tilting device 2, and the tilting device 2 drives the connecting arm 3 to tilt up and down or left and right with the casing 210. Moreover, the connecting arm 3 is connected with the side wall of the casing 210, thereby avoiding the connection between the connecting arm 3 and the casing 210 through a large-size connecting structure. In this way, the simple and compact design of the hair dryer 1000 is realized, and the practicability and reliability of the support structure 100 are improved.

[0043] Further, referring to Figure 1 and Figure 7 In an embodiment of the present application, the connecting arm 3 comprises a first connecting part 31 and a second connecting part 32, the first connecting part 31 is arranged at a distance from the air inlet end of the casing 210 and is connected with the tilting device 2, and the second connecting part 32 is bent and connected with the first connecting part 31 and is connected with the side wall of the casing 210.

[0044] In the embodiment, the first connecting part 31 is located at one end of the connecting arm 3 close to the tilting device 2, the first connecting part 31 is provided with a bolt hole for connecting and fixing with the tilting device 2, and the first connecting part 31 is provided with an arc-shaped groove to facilitate the swinging of the connecting arm 3 relative to the tilting device 2 in order to adapt to the outer contour shape of the tilting device 2. The second connecting part 32 is located at one end of the connecting arm 3 away from the tilting device 2, the second connecting part 32 is provided with a plurality of pivot shafts, the center of the pivot shafts is provided with a bolt hole for mounting and fixing with the casing 210. The first connecting part 31 and the air inlet end of the casing 210 form a space to prevent the connecting arm 3 from blocking the air inlet end of the casing 210, to ensure the air inlet amount of the casing 210 and to reduce turbulence, and to ensure the stable air inlet of the casing 210.

[0045] The connecting arm 3 can adopt a hollow structure under the premise of ensuring the supporting strength, the hollow inside the connecting arm 3 can be used for arranging the connecting lines of the motor and the like, and the second connecting part 32 and the casing 210 are provided with two wire ports in communication with each other, so that the connecting lines pass through the connecting arm 3 and enter the casing 210.

[0046] Further, referring to Figure 1 and Figure 7 In an embodiment of the present application, the connecting arm 3 comprises two second connecting parts 32, and the two second connecting parts 32 are connected to the opposite sides of the casing 210, respectively; or, the support structure 100 comprises two connecting arms 3, and the two connecting arms 3 are connected to the opposite sides of the casing 210, respectively.

[0047] In the embodiment, the connecting arm 3 comprises two second connecting portions 32, the two second connecting portions 32 are connected to opposite sides of the shell 210 respectively, the support has two end portions away from the first connecting portion 31, the two end portions are respectively provided with the second connecting portion 32, and the two end portions are connected to the opposite sides of the shell 210 through the second connecting portion 32 respectively. In this way, the connection strength of the head shaking device 2 and the shell 210 is strengthened, and the hair dryer 1000 is stably supported. Alternatively, the support structure 100 comprises two connecting arms 3, the two connecting arms 3 are connected to opposite sides of the shell 210 respectively, that is, the two connecting arms 3 can also be designed in a split type, and the two connecting arms 3 are connected with the head shaking device 2, and the two connecting arms 3 are connected to the side portions of the shell 210 respectively. The split type design can strengthen the connection strength of the head shaking device 2 and the shell 210, and facilitate flexible disassembly and assembly.

[0048] Further, referring to Figure 3 and Figure 4 In an embodiment of the utility model, the head shaking device 2 comprises 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 with the support main body 1, the second connecting structure 22 is connected with the connecting arm 3, the second connecting structure 22 is hinged with 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, and the elastic member 24 connects the first connecting structure 21 and the second connecting structure 22.

[0049] In the embodiment, the head shaking device 2 can comprise the first connecting structure 21 and the second connecting structure 22, the first connecting structure 21 can be a column structure connected with the support frame body, and the second connecting structure 22 can be a seat frame structure fixedly connected with the fan and / or the shell 210, after the first connecting structure 21 is connected with the second connecting structure 22, the shell 210 is installed on the vertical support frame body through the head shaking device 2 and can maintain horizontal blowing, and the stable operation of the hair dryer 1000 is guaranteed.

[0050] By arranging the swinging device 23 between the first connecting structure 21 and the second connecting structure 22, the swinging device 23 is connected with the first connecting structure 21 and the second connecting structure 22, the second connecting structure 22 can be driven to rotate relative to the first connecting structure 21 by the swinging device 23, the second connecting structure 22 can swing towards or away from the first connecting structure 21 in the height direction of the hair dryer 1000, and the second connecting structure 22 can drive the shell 210 to swing up and down in the height direction of the hair dryer 1000 under the driving action of the swinging device 23, the up and down swinging and blowing function of the hair dryer 1000 is realized, and the blowing range of the hair dryer 1000 is effectively expanded.

[0051] When the blowing device 1000 is in the horizontal blowing state, the elastic force exerted by the elastic member 24 on the second connecting structure 22 can completely or partially offset the gravity of the casing 210 and the blower and the like borne by the second connecting structure 22, thereby reducing the power consumption of the swing device 2 for maintaining the horizontal blowing of the blowing device 1000. When the blowing device 1000 is in the oblique downward blowing state, the gravity of the casing 210 and the second connecting structure 22 acts on the elastic member 24, causing the elastic member 24 to be elastically deformed. At this time, the swing device 23 continues to limit and self-lock the relative rotation of the first connecting structure 21 and the second connecting structure 22, so as to overcome the elastic force of the elastic member 24 and maintain the elastic deformation of the elastic member 24. In this way, the stable horizontal blowing or the oblique downward blowing of the blowing device 1000 is ensured.

[0052] When the swing device 23 drives the second connecting structure 22 to swing relative to the first connecting structure 21, the elastic member 24 can be restored to a certain elastic deformation to exert a force on the second connecting structure 22 and the casing 210, so that part of the elastic force of the elastic member 24 exerted on the second connecting structure 22 and part of the gravity of the casing 210 acting on the second connecting structure 22 are offset. In this way, the elastic member 24 can assist the swing device 23 in driving the second connecting structure 22 to stably swing with lower power consumption, so that the swing device 23 can adopt a low-power driving device with a smaller size, thereby realizing the miniaturization of the swing device 2, effectively reducing the overall size of the blowing device 1000, and improving the practicability and reliability of the swing device 2.

[0053] Further, please refer to Figure 3 and Figure 4 In an embodiment of the present application, 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 is in transmission connection with the mounting seat 214 and the connecting web 222. One side of the mounting seat 214 is provided with a first mounting protrusion 2141, one side of the connecting web 222 is provided with a second mounting protrusion 2221, and the two ends of the elastic member 24 are connected to the first mounting protrusion 2141 and the second mounting protrusion 2221, respectively.

[0054] In the embodiment, the first connecting structure 21 can be provided with a mounting seat 214 protruding on the end face thereof, which can be a sheet metal structure with certain structural strength erected on the end face of the first connecting structure 21, or can be a block structure with certain thickness, etc. At this time, the second connecting structure 22 can be provided with a connecting web 222 protruding on the side close to the first connecting structure 21, which can be a sheet metal structure with certain structural strength, and the connecting web 222 can be arranged at the outer side wall of the mounting seat 214, or can be arranged at the inner side wall of the mounting seat 214. For example, the mounting seat 214 and the second connecting structure 22 are both provided as a U-shaped sheet metal structure, the mounting seat 214 has two parallel walls, the second connecting structure 22 includes a mounting plate 221 and two parallel connecting webs 222 arranged on opposite sides of the mounting plate 221 and located outside the two parallel walls of the mounting seat 214, and the connecting webs 222 are hinged to the walls of the mounting seat 214. Further, the swing device 23 can be arranged between the connecting webs 222 and the mounting seat 214, and the swing device 23 drives the connecting webs 222 to swing relative to the mounting seat 214, so as to realize the swing design of the second connecting structure 22 relative to the first connecting structure 21 in the up-down direction, and ensure the stable operation of the swing mechanism.

[0055] The first mounting protrusion 2141 and the second mounting protrusion 2221 can be arranged opposite to each other in the up-down direction, so that the two ends of the elastic member 24 can be connected to the first mounting protrusion 2141 and the second mounting protrusion 2221, the elastic member 24 is connected to the first connecting structure 21 and the second connecting structure 22, and the elastic member 24 can stably pull the second connecting structure 22 when the swing device 23 drives the second connecting structure 22 to rise relative to the first connecting structure 21, so as to reduce the load acting on the swing device 23. By connecting the elastic member 24 to the first mounting protrusion 2141 and the second mounting protrusion 2221, the elastic member 24 can better avoid the swing device 23, realize more reasonable and compact space layout of the swing mechanism, facilitate maintenance and replacement of the elastic member 24, and further improve the practicality and structural reliability of the swing mechanism. It should be noted that the first mounting protrusion 2141 can be arranged in detachable connection with the mounting seat 214, and the second mounting protrusion 2221 can be arranged in detachable connection with the connecting web 222. For example, the second protrusion can be mounted on the connecting web 222 by a bolt through a screw hole arranged on the connecting web 222. Figure 3 and Figure 4For the convenience of observation, an explosion view is adopted, in which 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 with the connecting web 222.

[0056] The connecting web 222 and the mounting seat 214 are respectively provided with limit members to limit the rotation range of the connecting web 222 relative to the mounting seat 214, so as to prevent the structure from being easily damaged due to too large rotation angle, and the positions of the limit members can be set so that when the two limit members are in contact, the orientation of the blowing equipment 1000 just reaches a specific angle to meet the use demand of the user, for example, the air outlet of the blowing equipment 1000 is just upward, as shown in the figure. At this time, the blowing equipment 1000 can be stably blown upward by the limit members without additional power consumption of the swing device 2 to limit the orientation, thereby saving energy consumption.

[0057] Please refer to Figure 3 and Figure 4 In an embodiment of the utility model, the swing device 2 further 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 swing device 23 is connected to the mounting seat 214 or the second connecting structure 22, and the swing device 23 drives the connecting web 222 to swing relative to the mounting seat 214 around the central axis of the connecting shaft 25.

[0058] In the embodiment, the swing device 23 can pass through the mounting seat 214 and the connecting web 222 by the connecting shaft 25, 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 in transmission connection 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 in transmission connection with the mounting seat 214.
