Description

Technical Field

[0001] This application belongs to the field of fan technology, specifically relating to fans. Background Technology

[0002] A fan is a device that blows air into the environment, improving the temperature and overall comfort for the user. Fans generally include tall, floor-standing fans and shorter, desktop fans that can be placed on a desk or other surface. Users need to purchase both types of fans, which not only takes up space but also increases costs. Utility Model Content

[0003] In view of this, this application provides a fan, the fan including a base module and an air outlet device, the base module being used to support the ground, the air outlet device being detachably connected to the base module, the air outlet device including a detachably connected air outlet module and a support module, the air outlet module being used to blow air outward, and the support module having an unfolded state and a folded state;

[0004] When the air outlet device is connected to the base module, the air outlet module is installed in the base module, and the support module is in the combined state and is located inside the base module, abutting against the air outlet module. When the air outlet module is separated from the base module, at least a portion of the support module can protrude from the base module. After the support module is removed from the base module, it can still be installed in the air outlet module. When the support module is in the unfolded state, the support module is used to support the surface to be supported.

[0005] Based on this, the base module includes a base, a support rod, and a moving component. The base is used to support the ground, the support rod is disposed on the base, and the moving component is disposed within the support rod. The moving component includes a fixing member, a moving member, and an elastic member. The fixing member is fixed within the support rod, the moving member is mounted on the fixing member and can move relative to the fixing member along the axial direction of the moving member, the moving member and the fixing member enclose a receiving space, and the elastic member is disposed within the receiving space, with the opposite ends of the elastic member respectively connected to the fixing member and the moving member.

[0006] When the air outlet device is connected to the base module, the air outlet module abuts against the support module located inside the support rod, and the support module abuts against the movable member, causing the movable member to move in a direction closer to the base, while the elastic member is in a compressed state. When the air outlet module is separated from the base module, the compressed elastic member drives the movable member to move in a direction away from the base, thereby causing the support module to also move in a direction away from the base.

[0007] Based on this, the bottom wall of the fixing member is provided with a boss, and the elastic member is connected to the boss.

[0008] Based on this, the side wall of the fixing member is provided with a limiting hole, and the end of the moving member near the base is provided with a limiting part protruding in the radial direction of the moving member. When the moving member is installed on the fixing member, the limiting part is provided in the limiting hole.

[0009] When the air outlet module is separated from the base module, the elastic element in the compressed state drives the moving element to move away from the base. When the moving element moves a preset distance, the limiting part abuts against the top wall of the limiting hole.

[0010] Based on this, the support module includes a housing assembly and multiple support assemblies. The multiple support assemblies are arranged circumferentially along the housing assembly and are all rotatably connected to the housing assembly. The housing assembly is provided with a plug-in groove along its axial direction. The end of the air outlet module is provided with an installation space, and the inner wall of the installation space is provided with a plug-in part.

[0011] When the air outlet device is connected to the base module, the air outlet module is installed on the base module, the plug-in part is offset from the plug-in slot, and the plug-in part abuts against the housing assembly; when the air outlet module is separated from the base module and the support module is removed from the base module, at least a portion of the housing assembly is installed in the installation space, and the plug-in part is located in the plug-in slot.

[0012] Based on this, when the air outlet module separates from the base module, the support module moves away from the ground, at least a portion of the housing assembly protrudes from the base module, and at least a portion of the insertion slot is exposed.

[0013] Based on this, the outer peripheral side of the housing assembly is provided with a mating rib. When at least a part of the housing assembly is installed in the installation space, the mating rib abuts against the inner wall of the installation space, and the housing assembly is interference-fitted with the air outlet module through the mating rib.

[0014] Based on this, the support module includes a linkage component and multiple support components. The multiple support components are arranged circumferentially along the linkage component and are all connected to the linkage component. The linkage component can move in a direction that is closer to or farther away from the air outlet module.

[0015] Wherein, after the support module is removed from the base module, the linkage component can move and drive the multiple support components to rotate synchronously in mutually distancing directions, thereby placing the support module in the unfolded state, and the multiple support components are used to support the surface to be supported.

[0016] Based on this, when the support module is in the merged state, at least a portion of the linkage component protrudes from the plurality of support components in a direction away from the air outlet module;

[0017] Wherein, after the support module is removed from the base module, the linkage component in the support module in the merged state can abut against the surface to be supported, and when pressure is applied to the linkage component along the direction of the surface to be supported, the linkage component moves in the direction closer to the air outlet module, and drives the multiple support components to rotate synchronously in the direction away from each other, so that the support module is in the unfolded state.

[0018] Based on this, after the support module is removed from the base module, the linkage component is moved away from the air outlet module, and the multiple support components are driven to rotate synchronously in mutually distancing directions, thereby putting the support module into the unfolded state.

[0019] The fan provided in this application allows for conversion between a desktop fan and a standing fan by detachably connecting the air outlet device to the base module. When the air outlet device is connected to the base module, it functions as a standing fan; when the air outlet device is detached from the base module, it functions as a desktop fan. Furthermore, the air outlet device includes an air outlet module for airflow and a support module that has an extended state and a folded state. In this embodiment, the air outlet module can be detachably connected to the support module. In other words, the air outlet module and the support module are not fixedly connected; the support module can be installed onto the air outlet module to form a single unit, or it can be detached from the air outlet module to become two independent components.

[0020] When the air outlet device is connected to the base module, the air outlet module can be installed on the base module. At this time, the support module is in a combined state and located inside the base module, with the support module abutting against the air outlet module. The support module and the air outlet module are in a separate state. When the air outlet module is separated from the base module, the air outlet module no longer abuts against the support module, and at least a portion of the support module can protrude from the base module by various methods for easy removal by the user. The user can then remove the support module from the base module and install it onto the air outlet module. When the support module is in the unfolded state, it can be supported on the surface to be supported, allowing the air outlet device to be supported on the surface.

[0021] In summary, this application, based on the realization of a dual-purpose (tabletop and stand-up) fan, reduces the transport size of the air outlet device by allowing the air outlet module to be detachably connected to the support module, enabling separate transport of the air outlet module and the support module during transportation. Furthermore, if either the support module or the air outlet module is damaged and needs replacement, only the damaged module needs to be replaced, without replacing the entire air outlet device, thus reducing maintenance and replacement costs.

Detailed Implementation

[0044] The following are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.

[0045] In view of this, in order to solve the above-mentioned technical problems, this application provides a fan, which please refer to. Figures 1-5 , Figure 1 This is a three-dimensional structural diagram of a vertical fan in one embodiment of this application. Figure 2 for Figure 1 The diagram shows the vertical fan after the air outlet module and the base module have been separated. Figure 3 for Figure 2 The diagram shown illustrates the vertical fan after the support module and base module have been separated. Figure 4 This is a three-dimensional structural diagram of a desktop fan according to one embodiment of this application. Figure 5 for Figure 4 The image shown is an exploded view of a desktop fan.

[0046] The fan 1 provided in this embodiment includes a base module 10 and an air outlet device 20a. The base module 10 is used to support the ground, and the air outlet device 20a is detachably connected to the base module 10. The air outlet device 20a includes a detachably connected air outlet module 20 and a support module 30. The air outlet module 20 is used to blow air outward, and the support module 30 has an unfolded state and a folded state.

[0047] When the air outlet device 20a is connected to the base module 10, the air outlet module 20 is installed in the base module 10, and the support module 30 is in a combined state and is located inside the base module 10, abutting against the air outlet module 20. When the air outlet module 20 is separated from the base module 10, at least a portion of the support module 30 can protrude from the base module 10, and after the support module 30 is removed from the base module 10, it can still be installed in the air outlet module 20. When the support module 30 is in an unfolded state, the support module 30 is used to support the surface to be supported.

[0048] Fan 1 is a device that can blow air and can be used in various scenarios, such as indoors and outdoors, to improve the temperature of the external environment and enhance the overall comfort of the user. The fan 1 provided in this embodiment consists of a base module 10 and an air outlet device 20a. The base module 10 is a component placed on the ground, having a certain height, and capable of housing the air outlet device 20a. The air outlet device 20a is detachably connected to the base module 10. When the air outlet device 20a is installed and connected to the base module 10, the fan 1 can be referred to as a standing fan. When the air outlet device 20a is detached from the base module 10 and separated from it, the air outlet device 20a can be placed independently on a support surface, in which case it can be referred to as a desktop fan. Optionally, the support surface includes, but is not limited to, the ground, a desktop, etc. This embodiment only uses a desktop as an illustrative example.

[0049] Therefore, the fan 1 provided in this embodiment can be converted between desktop and stand fan. Users only need to purchase an air outlet device 20a and a base module 10. When they want a desktop fan, they only need to use the air outlet device 20a. When they want a stand fan, they can install the air outlet device 20a on the base module 10. This can reduce space occupation and save costs.

[0050] The air outlet device 20a consists of an air outlet module 20 and a support module 30. The air outlet module 20 is used to blow air to the outside. Optionally, the air outlet module 20, based on the air outlet principle, includes, but is not limited to, circulating air type air outlet module 20, inertial flow air outlet module 20, centrifugal air outlet module 20, axial flow air outlet module 20, etc. Optionally, the air outlet module 20 can blow cold air or hot air to the outside, and can also spray water mist outward at the same time while blowing air, which is carried by the wind to the outside environment.

[0051] The support module 30 is mainly used to support the air outlet module 20 on the surface to be supported when the air outlet device 20a is separated from the base module 10 and used as a desktop fan. The support module 30 has an unfolded state and a folded state. When the support module 30 is in the folded state, it can be placed inside the base module 10. When the support module 30 is in the unfolded state, it can serve as a support component for the air outlet module 20.

[0052] In this embodiment, the air outlet module 20 can be detachably connected to the support module 30. In other words, the air outlet module 20 and the support module 30 are not fixedly connected together. The support module 30 can be installed on the air outlet module 20 to become a whole, and the support module 30 can also be detached from the air outlet module 20 to become two independent parts.

[0053] When the air outlet device 20a is connected to the base module 10, the air outlet module 20 can be installed on the base module 10. At this time, the support module 30 is in a combined state and located inside the base module 10, with the support module 30 abutting against the air outlet module 20. The support module 30 and the air outlet module 20 are in a separated state. When the air outlet module 20 is separated from the base module 10, the air outlet module 20 no longer abuts against the support module 30, and at least a portion of the support module 30 can protrude from the base module 10 by various methods for easy access by the user. For example, the support module 30 can automatically move upward in a direction away from the ground, or the user can manually move the support module 30 upward in a direction away from the ground, or a motor can move the support module 30 upward in a direction away from the ground, ultimately causing at least a portion of the support module 30 to protrude from the base module 10 for easy access by the user. This embodiment and the following description only illustrate the possibility that the support module 30 can automatically move upward in a direction away from the ground. The user can then completely remove the support module 30 from the base module 10 and install the support module 30 onto the air outlet module 20. When the support module 30 is in the unfolded state, it can be supported on the surface to be supported, and the air outlet device 20a can be supported on the surface to be supported using the support module 30.

[0054] In summary, this embodiment, while achieving a dual-purpose (tabletop and stand-up) fan, allows the air outlet module 20 to be detachably connected to the support module 30. This enables the air outlet module 20 and support module 30 to be transported separately during transportation, thereby reducing the transport size of the air outlet device 20a. Furthermore, if either the support module 30 or the air outlet module 20 is damaged and needs replacement, only the damaged module needs to be replaced, without replacing the entire air outlet device 20a, thus reducing maintenance and replacement costs.

[0055] Please refer to this as well. Figures 6-8 , Figure 6 for Figure 1 The diagram shows the three-dimensional structure of the vertical fan after removing part of the support rod. Figure 7 for Figure 6 The exploded view of the vertical fan shown. Figure 8 for Figure 1The diagram shows a partial cross-sectional view of the vertical fan. In this embodiment, the base module 10 includes a base 11, a support rod 12, and a moving component 13. The base 11 is used to support the ground, the support rod 12 is disposed on the base 11, and the moving component 13 is disposed within the support rod 12. The moving component 13 includes a fixing member 14, a moving member 15, and an elastic member 16. The fixing member 14 is fixed within the support rod 12, the moving member 15 is mounted on the fixing member 14 and can move relative to the fixing member 14 along the axial direction of the moving member 15, and the moving member 15 and the fixing member 14 enclose a receiving space 130. The elastic member 16 is disposed within the receiving space 130, and the opposite ends of the elastic member 16 are respectively connected to the fixing member 14 and the moving member 15.

[0056] When the air outlet device 20a is connected to the base module 10, the air outlet module 20 abuts against the support module 30 located within the support rod 12, and the support module 30 abuts against the movable member 15, causing the movable member 15 to move in a direction closer to the base 11, while the elastic member 16 is in a compressed state. When the air outlet module 20 is separated from the base module 10, the compressed elastic member 16 drives the movable member 15 to move in a direction away from the base 11, thereby causing the support module 30 to also move in a direction away from the base 11.

[0057] The base module 10 includes a base 11, a support rod 12, and a moving component 13. The base 11 is circular and supported on the ground. The rod-shaped support rod 12 is located on the base 11 and provides a certain height for the air outlet device 20a, enabling it to function as a vertical fan. In addition, a moving component 13 can be added inside the support rod 12. The moving component 13 is mainly used to control the movement of the support component 50. Specifically, the moving component 13 consists of a fixed member 14, a moving member 15, and an elastic member 16. The fixed member 14 is fixed inside the support rod 12; that is, the fixed member 14 is stationary and will not move. The moving member 15 is mounted on the fixed member 14, and the moving member 15 is not fixedly connected to the fixed member 14 but is movably connected. The moving member 15 can move up and down relative to the fixed member 14 along the axial direction of the moving member 15. The movable member 15 and the fixed member 14 cooperate to form a receiving space 130. The elastic member 16 can be installed in the receiving space 130, and one end of the elastic member 16 is connected to the fixed member 14, and the other end is connected to the movable member 15.

[0058] When the air outlet device 20a is connected to the base module 10, the air outlet module 20 is mounted on the support rod 12, and the support module 30 is located inside the support rod 12. The air outlet module 20 abuts against the support module 30, allowing the support module 30 to abut against and press down on the moving member 15. This causes the moving member 15 to move downwards in the direction closer to the base 11, compressing the elastic member 16. When the air outlet module 20 separates from the base module 10, the air outlet module 20 no longer abuts against the support module 30. The compressed elastic member 16 can drive the moving member 15 to move upwards in the direction away from the base 11, thereby causing the support module 30 to also move in the direction away from the base 11. This continues until the elasticity of the elastic member 16 is fully released. At this point, the elastic member 16 returns to a balanced state, and the upper end of the support module 30 protrudes from the support rod 12 for easy removal by the user.

[0059] Please refer to this as well. Figures 9-12 , Figure 9 This is a three-dimensional structural diagram of the moving component in one embodiment of this application. Figure 10 for Figure 9 The diagram shows a three-dimensional structure of the movable component from another perspective. Figure 11 for Figure 9 An exploded view of the moving component shown. Figure 12 for Figure 9 The diagram shows a cross-sectional view of the movable component. In this embodiment, the bottom wall of the fixing member 14 is provided with a boss 140, and the elastic member 16 is connected to the boss 140. By connecting the elastic member 16 to the protruding boss 140, the length of the elastic member 16 can be reduced, the degree of compression of the elastic member 16 can be increased, thereby allowing the elastic member 16 to better drive the movable member 15 and the support module 30 to move upward.

[0060] In this embodiment, the side wall of the fixing member 14 is provided with a limiting hole 141, and the end of the moving member 15 near the base 11 is provided with a limiting part 151 protruding in the radial direction of the moving member 15. When the moving member 15 is installed on the fixing member 14, the limiting part 151 is provided in the limiting hole 141.

[0061] When the air outlet module 20 is separated from the base module 10, the elastic member 16 in the compressed state drives the moving member 15 to move away from the base 11. When the moving member 15 moves a preset distance, the limiting part 151 abuts against the top wall of the limiting hole 141.

[0062] A limiting hole 141 can be formed on the side wall of the fixing member 14. The limiting hole 141 extends upward along the axial direction of the fixing member 14, but the limiting hole 141 does not penetrate the top of the fixing member 14, that is, the limiting hole 141 has a top wall. The lower end of the moving member 15 near the base 11 can be provided with a limiting part 151 protruding outward along the radial direction of the moving member 15. When the moving member 15 is installed on the fixing member 14, the limiting part 151 can be disposed in the limiting hole 141.

[0063] As can be seen from the above, when the air outlet module 20 is separated from the base module 10, the elastic member 16 in the compressed state can drive the moving member 15 to move upward in the direction away from the base 11. When the moving member 15 moves a preset distance, the limiting part 151 will abut against the top wall of the limiting hole 141, and the limiting part 151 will no longer be able to move upward, thereby preventing the moving member 15 from coming off the fixing member 14.

[0064] Optionally, the elastic element 16 can be in a balanced state or still in a compressed state at this time.

[0065] Please refer to this as well. Figures 13-14 , Figure 13 This is a three-dimensional structural diagram of a portion of the air outlet module and a portion of the support module when the air outlet device is connected to the base module in one embodiment of this application. Figure 14 for Figure 4 The diagram shows an exploded view of the housing assembly and part of the air outlet module in the desktop fan. In this embodiment, the support module 30 includes a housing assembly 60 and a plurality of support assemblies 50. The plurality of support assemblies 50 are arranged circumferentially along the housing assembly 60 and are all rotatably connected to the housing assembly 60. The housing assembly 60 is provided with a plug-in groove 61 along its axial direction. The end of the air outlet module 20 is provided with a mounting space 200, and the inner wall of the mounting space 200 is provided with a plug-in portion 21.

[0066] When the air outlet device 20a is connected to the base module 10, the air outlet module 20 is installed on the base module 10, the plug-in part 21 is offset from the plug-in slot 61, and the plug-in part 21 abuts against the housing assembly 60. When the air outlet module 20 is separated from the base module 10 and the support module 30 is removed from the base module 10, at least a portion of the housing assembly 60 is installed in the installation space 200, and the plug-in part 21 is located in the plug-in slot 61.

[0067] The support module 30 consists of a housing assembly 60 and support components 50. The housing assembly 60 is used to connect the air outlet module 20. Multiple support components 50 are arranged circumferentially around the housing assembly 60, that is, multiple support components 50 are arranged in a circle around 360°. All multiple support components 50 are rotatably connected to the housing assembly 60. When the multiple support components 50 are unfolded, the support module 30 is in the unfolded state. At this time, multiple support components 50 can simultaneously support the surface to be supported, improving the support stability of the air outlet device 20a. When the multiple support components 50 are combined, the support module 30 is in the combined state. At this time, the volume of the support module 30 can be reduced, making it easier to place the support module 30 inside the base module 10.

[0068] The housing assembly 60 is provided with a plug-in groove 61 along its axial direction, that is, the plug-in groove 61 extends along the axial direction of the housing assembly 60. The lower end of the air outlet module 20 is provided with a mounting space 200, and a plug-in part 21 can be provided on the inner wall of the mounting space 200, which also extends along the axial direction of the housing assembly 60.

[0069] When the air outlet device 20a is connected to the base module 10, the air outlet module 20 is installed in the base module 10, the support module 30 is located inside the base module 10, and the lower end of the air outlet module 20 abuts against the housing assembly 60 at the upper end of the support module 30. At this time, the insertion part 21 and the insertion slot 61 can be staggered, and the insertion part 21 is used to abut against the housing assembly 60 to press down the support module 30. When the air outlet module 20 is separated from the base module 10, and the support module 30 is removed from the base module 10, and the support module 30 is installed in the air outlet module 20, the angle between the support module 30 and the air outlet module 20 can be controlled, that is, the angle between the insertion part 21 and the insertion slot 61 can be controlled, so that the insertion part 21 corresponds to the insertion slot 61, achieving aligned installation and avoiding reverse installation. This allows at least a portion of the housing assembly 60 to be installed within the installation space 200, with the insertion part 21 positioned within the insertion slot 61, thus successfully completing the installation.

[0070] In summary, through the cooperation between the plug-in part 21 and the plug-in slot 61, the air outlet module 20 can be made to abut against the support module 30, and the air outlet module 20 and the support module 30 can be aligned and installed, thereby improving the installation accuracy.

[0071] Optionally, the air outlet module 20 is provided with a first alignment part, and the support rod 12 is provided with a second alignment part. The air outlet module 20 and the support rod 12 can be aligned and installed by the cooperation of the first alignment part and the second alignment part. The first alignment part includes one of an alignment groove and an alignment block, and the second alignment part includes the other of an alignment groove and an alignment block.

[0072] Please refer to Figure 15 , Figure 15 for Figure 1The diagram shows a three-dimensional structure of the vertical fan after the air outlet module has been removed. In this embodiment, when the air outlet module 20 is separated from the base module 10, the support module 30 moves away from the ground, at least a portion of the housing assembly 60 protrudes from the base module 10, and at least a portion of the insertion slot 61 is exposed.

[0073] As can be seen from the above, when the air outlet module 20 separates from the base module 10, the support module 30 moves upward in a direction away from the ground, and at least a portion of the support module 30 protrudes from the base module 10, that is, at least a portion of the housing assembly 60 protrudes from the base module 10. In other words, when a vertical fan is needed, when the support module 30 is just placed on the base module 10, due to the action of the elastic member 16, the support module 30 is not completely placed inside the base module 10, and the housing assembly 60 at the upper end of the support module 30 can protrude from the base module 10. Based on this, this embodiment can expose at least a portion of the insertion slot 61. In this way, when the air outlet module 20 abuts against the support module 30 and is pressed down, the insertion part 21 and the insertion slot 61 can be better misaligned, avoiding the insertion part 21 and the insertion slot 61 being directly aligned, thus preventing the support module 30 from being pressed down into the base module 10.

[0074] In summary, by exposing at least a portion of the insertion slot 61, the insertion slot 61 can serve as an identifier.

[0075] Please refer to this again. Figure 14 In this embodiment, the outer peripheral side of the housing assembly 60 is provided with a mating rib 62. When at least a part of the housing assembly 60 is installed in the installation space 200, the mating rib 62 abuts against the inner wall of the installation space 200, and the housing assembly 60 is interference-fitted with the air outlet module 20 through the mating rib 62.

[0076] A mating rib 62 may be provided on the outer peripheral side of the sidewall of the housing assembly 60, and the mating rib 62 extends along the axial direction of the housing assembly 60. When there are multiple mating ribs 62, the multiple mating ribs 62 are spaced apart along the circumferential direction of the housing assembly 60. The arrangement of the mating ribs 62 makes the outer diameter of the housing assembly 60 larger than the inner diameter of the mounting space 200. When the support module 30 is installed in the mounting space 200 of the air outlet module 20, the mating rib 62 abuts against the inner wall of the mounting space 200. Therefore, in this embodiment, the housing assembly 60 is interference-fitted with the air outlet module 20 through the mating ribs 62, thereby improving the connection performance between the air outlet module 20 and the support module 30.

[0077] Optionally, the top of the rib 62 is provided with a guide slope 620, so that the support module 30 plays a guiding role when it is installed in the air outlet module 20.

[0078] Please refer to this as well. Figures 16-19 , Figure 16This is a front view of the support module in a merged state according to one embodiment of this application. Figure 17 This is a three-dimensional structural diagram of the support module in the deployed state according to one embodiment of this application. Figure 18 This is a front view of the support module in a merged state according to another embodiment of this application. Figure 19 This is a front view of the support module in its deployed state according to another embodiment of this application. In this embodiment, the support module 30 includes a linkage component 40 and a plurality of support components 50. The plurality of support components 50 are arranged circumferentially along the linkage component 40 and are all connected to the linkage component 40. The linkage component 40 can move in a direction that is closer to or farther away from the air outlet module 20.

[0079] In this process, after the support module 30 is removed from the base module 10, the linkage component 40 can move and drive multiple support components 50 to rotate synchronously in directions away from each other, so that the support module 30 is in an unfolded state, and the multiple support components 50 are used to support the surface to be supported.

[0080] In addition to multiple support components 50, the support module 30 may also include a linkage component 40. The multiple support components 50 are arranged circumferentially along the linkage component 40, and the linkage component 40 can connect to multiple support components 50 simultaneously. The linkage component 40 can move up and down in the direction of approaching or moving away from the air outlet module 20. Therefore, when the linkage component 40 moves, it can drive multiple support components 50 to move simultaneously. This eliminates the need to individually control the movement and merging of multiple support components 50 one by one, reducing the difficulty of operation for the user.

[0081] Specifically, when the support module 30 needs to be deployed, simply controlling the support module 30 to move in a certain direction will cause the linkage component 40 to drive the multiple support components 50 to deploy. When the support module 30 needs to be merged, simply controlling the support module 30 to move in the opposite direction will cause the linkage component 40 to drive the multiple support components 50 to merge and retract.

[0082] In summary, this embodiment achieves a dual-purpose (tabletop and stand-up) fan. During the unfolding and merging of the support component 50, it is not necessary to rotate multiple support components 50 sequentially. With the cooperation of the linkage component 40, only the movement of the linkage component 40 needs to be controlled individually to simultaneously drive the unfolding and merging of multiple support components 50, thus reducing the difficulty of operation for users.

[0083] Please refer to this again. Figures 16-17 In this embodiment, when the support module 30 is in a merged state, at least a portion of the linkage component 40 protrudes from the plurality of support components 50 in a direction away from the air outlet module 20.

[0084] When the support module 30 is removed from the base module 10, the linkage component 40 in the combined support module 30 can abut against the surface to be supported. When pressure is applied to the linkage component 40 along the direction of the surface to be supported, the linkage component 40 moves in the direction closer to the air outlet module 20 and drives multiple support components 50 to rotate synchronously in directions away from each other, thereby putting the support module 30 in the unfolded state.

[0085] In this embodiment, when the support module 30 is in the merged state, at least a portion of the linkage component 40 protrudes from the plurality of support components 50 in a direction away from the air outlet module 20, that is, at least a portion of the linkage component 40 protrudes downward from the support components 50. When the support module 30 is in the merged state, the linkage component 40 will be the first to contact the contact surface.

[0086] Based on the above structure, when the air outlet device 20a is connected to the base module 10, the support module 30 is in a combined state and is located inside the base module 10, while at least a portion of the air outlet module 20 is located outside the base 11, and the support module 30 is hidden inside the base module 10. When the air outlet device 20a is disassembled from the base module 10, the support module 30 is still in a combined state. After the support module 30 is installed on the air outlet module 20, it can first abut against the surface to be supported. As can be seen from the above, because the lower end of the linkage component 40 protrudes further, the linkage component 40 will abut against the surface to be supported. Subsequently, pressure can be applied to the air outlet device 20a and the linkage component 40 along the direction of the surface to be supported. That is, when downward pressure is applied, the linkage component 40 can move upward along the direction close to the air outlet module 20. When the linkage component 40 moves upward, it can drive multiple support components 50 to rotate synchronously in directions away from each other, thereby putting the support module 30 into an unfolded state, and the multiple support components 50 supporting the surface to be supported. Therefore, it is only necessary to place the air outlet device 20a on the surface to be supported and press down on the air outlet device 20a to achieve unfolding, without the need for additional control of the linkage component 40, which can further reduce the user's operating difficulty.

[0087] It is worth noting that in this embodiment, initially the linkage component 40 is in contact with the surface to be supported. As the linkage component 40 rises and the multiple support components 50 unfold, the multiple support components 50 can also support the surface to be supported. During this process, the linkage component 40 can always remain in contact with the surface to be supported, or after the linkage component 40 moves to a preset height, only the multiple support components 50 support the surface to be supported, and the linkage component 40 separates from the surface to be supported.

[0088] When the support components 50 need to be merged, the linkage component 40 can be moved downwards in a direction away from the air outlet module 20, allowing multiple support components 50 to merge and retract. Alternatively, one or a small number of support components 50 can be controlled to merge and retract individually, thereby driving the linkage component 40 to move downwards in a direction away from the air outlet module 20, and then the linkage component 40 drives the other multiple support components 50 to merge and retract. Therefore, whether unfolding or merging, it is not necessary to control the movement of multiple support components 50 one by one; simply moving the linkage component 40 is sufficient to achieve the unfolding and merging of multiple support components 50.

[0089] In summary, this embodiment, while achieving a dual-purpose (tabletop and stand-mounted) fan, eliminates the need for multiple support components 50 to rotate sequentially during the unfolding and merging process. Through the coordination of the linkage component 40, only the movement of the linkage component 40 needs to be controlled individually, thereby synchronously driving the unfolding and merging of multiple support components 50, reducing the difficulty of user operation. The specific structure of the support module 30 has been protected in other patents filed on the same day, and will not be elaborated upon here.

[0090] Please refer to this again. Figures 18-19 In this embodiment, after the support module 30 is moved out of the base module 10, the linkage component 40 is moved away from the air outlet module 20, and multiple support components 50 are driven to rotate synchronously in directions away from each other, so that the support module 30 is in the unfolded state.

[0091] In another embodiment, when the air outlet device 20a is connected to the base module 10, the support module 30 is in a combined state and is located inside the base module 10, while at least a portion of the air outlet module 20 is located outside the base 11, and the support module 30 is concealed within the base module 10. When the air outlet device 20a is disassembled from the base module 10, the support module 30 is still in a combined state. After the support module 30 is installed on the air outlet module 20, it is only necessary to move the linkage component 40 downwards in a direction away from the air outlet module 20. Since the linkage component 40 connects multiple support components 50, the linkage can drive the multiple support components 50 to rotate synchronously in mutually distancing directions, thereby putting the support module 30 in an unfolded state, and the multiple support components 50 are used to support the surface to be supported. Therefore, the unfolding operation of the multiple support components 50 can be achieved simply by controlling the linkage component 40.

[0092] When the support components 50 need to be merged, the linkage component 40 can be moved upwards along the direction closer to the air outlet module 20, allowing multiple support components 50 to merge and retract. Alternatively, one or a small number of support components 50 can be controlled to merge and retract individually, thereby driving the linkage component 40 to move upwards along the direction closer to the air outlet module 20, and then the linkage component 40 drives the other multiple support components 50 to merge and retract. Therefore, whether unfolding or merging, it is not necessary to control the movement of multiple support components 50 one by one; simply moving the linkage component 40 is sufficient to achieve the unfolding and merging of multiple support components 50.

[0093] In summary, this embodiment, while achieving a dual-purpose (tabletop and stand-mounted) fan, eliminates the need for multiple support components 50 to rotate sequentially during the unfolding and merging process. Through the coordination of the linkage component 40, only the movement of the linkage component 40 needs to be controlled individually to synchronously drive the unfolding and merging of multiple support components 50, reducing the difficulty of user operation. The specific structure of the support module 30 has been protected in other patents filed on the same day, and will not be elaborated upon here.
