[0002] A fan is a device that blows air into the outside environment, improving the ambient temperature and overall user comfort. The air outlet mechanism in a fan has two states: a collapsed state and an expanded state. To switch from the collapsed state to the expanded state, multiple support members must be manually deployed one by one, which is inconvenient for the user. Summary of the Invention

Furthermore, the linkage assembly in the combined support module can abut the surface to be supported, i.e., the linkage assembly is positioned further downward to abut the surface to be supported. When pressure is applied to the linkage assembly, the linkage assembly can move in a direction toward the air outlet module. Since the linkage assembly connects multiple support assemblies, it can drive the multiple support assemblies to rotate synchronously in a direction away from each other, thereby placing the support module in an expanded state and supporting the multiple support assemblies on the surface to be supported.

It should be noted that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.

[0046] In view of this, in order to solve the above technical problems, this application provides a fan, please refer to Figure 1-Figure 7 , Figure 1 This is a schematic diagram of the three-dimensional structure when the fan is a vertical fan in one embodiment of the present application.

Figure 7 This is a schematic diagram of the three-dimensional structure of the support module in an embodiment of the present application when it is in an expanded state.

[0047] 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 be supported on the ground. The air outlet device 20a is detachably connected to the base module 10. The air outlet device 20a includes a connected air outlet module 20 and a support module 30. The air outlet module 20 is used to blow air outward. The support module 30 has an expanded state and a merged state. The support module 30 includes a linkage component 40 and multiple support components 50. The multiple support components 50 are arranged along the circumference of the linkage component 40 and are all connected to the linkage component 40. When the support module 30 is in the merged state, at least a portion of the linkage component 40 protrudes from the multiple support components 50 in a direction away from the air outlet module 20.

[0048] When the air outlet device 20a is connected to the base module 10, the support module 30 is in a combined state, with at least a portion of the support module 30 disposed within the base module 10, and at least a portion of the air outlet module 20 disposed outside the base module 10. When the air outlet device 20a is disassembled from the base module 10, and the linkage assembly 40 is subjected to a force acting in the direction of the air outlet module 20, the linkage assembly 40 moves in a direction toward the air outlet module 20, and drives the multiple support assemblies 50 to rotate synchronously in a direction away from each other, thereby placing the support module 30 in an expanded state, with the multiple support assemblies 50 supported on the surface to be supported.

[0049] The fan 1 is a device that can blow air and can be used in various scenarios such as indoors and outdoors. It can improve the temperature of the external environment and enhance the overall comfort of the user. The fan 1 provided in this embodiment is composed of a base module 10 and an air outlet device 20a. The base module 10 is a component placed on the ground, has a certain height, and can be equipped with 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 called a vertical fan. When the air outlet device 20a is removed from the base module 10 and separated from the base module 10, the air outlet device 20a can be placed alone on the surface to be supported. At this time, the air outlet device 20a can be called a desktop fan. Optionally, the surface to be supported includes but is not limited to the ground, a desktop, etc. This embodiment is only schematically illustrated with the surface to be supported being a desktop.

[0050] Therefore, the fan 1 provided in this embodiment can be converted into a desktop or stand-up fan. The user only needs to purchase an air outlet device 20a and a base module 10. When a desktop fan is needed, only the air outlet device 20a is used. When a stand-up fan is needed, the air outlet device 20a is installed on the base module 10, which can reduce space occupation and save costs.

[0051] The air outlet device 20a comprises an air outlet module 20 and a support module 30. The air outlet module 20 is used to blow air to the outside. Optionally, based on the air outlet principle, the air outlet module 20 includes but is not limited to a circulating air outlet module 20, a flow air outlet module 20, a centrifugal air outlet module 20, an axial air outlet module 20, and the like. Optionally, the air outlet module 20 can blow cold air or hot air to the outside, and simultaneously spray water mist outward, which is driven by the wind and drifts to the outside environment.

[0052] The support module 30 is mainly used to support the air outlet module 20 on a support surface when the air outlet device 20a is separated from the base module 10 and used independently as a desktop fan. The support module 30 and the air outlet module 20 can be fixedly connected or detachably connected. This embodiment only schematically illustrates the fixed connection between the support module 30 and the air outlet module 20. The support module 30 has an expanded state and a combined state. In the combined state, the support module 30 can be installed on the base module 10 together with the air outlet module 20, so that the support module 30 can be placed inside the base module 10. At this time, at least a portion of the support module 30 is placed inside the base module 10, and at least a portion of the air outlet module 20 is placed outside the base module 10 and connected to the base module 10. The support module 30 in the expanded state is used to support the air outlet device 20a on a support surface when the air outlet device 20a is separated from the base module 10 and used independently.

[0053] The support module 30 includes a linkage assembly 40 and multiple support assemblies 50. The multiple support assemblies 50 are arranged circumferentially around the linkage assembly 40, forming a 360° circle. When the multiple support assemblies 50 are deployed, the support module 30 is in an deployed state. In this state, the multiple support assemblies 50 can simultaneously support the supported surface, improving the support stability of the air outlet device 20a. When the multiple support assemblies 50 are combined, the support module 30 is in a combined state. This reduces the size of the support module 30 and facilitates its placement within the base module 10.

[0054] The linkage assembly 40 can simultaneously connect to multiple support assemblies 50. Therefore, when the linkage assembly 40 moves, it can drive the simultaneous movement of the multiple support assemblies 50. This eliminates the need to individually control the movement and merging of the multiple support assemblies 50, reducing operational complexity for the user. Furthermore, in this embodiment, when the support module 30 is in the merged state, at least a portion of the linkage assembly 40 protrudes from the multiple support assemblies 50 in a direction away from the air outlet module 20. That is, at least a portion of the linkage assembly 40 protrudes downward from the support assemblies 50. When the support module 30 is in the merged state, the linkage assembly 40 will first contact the surface to be contacted, such as another object.

[0055] 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 merged state, with at least a portion of the support module 30 disposed within the base module 10, while at least a portion of the air outlet module 20 is disposed outside the base module 10, with the support module 30 concealed within the base module 10. When the air outlet device 20a is detached from the base module 10, the support module 30 of the air outlet device 20a remains in the merged state. At this time, the portion of the linkage assembly 40 in the support module 30 that protrudes from the multiple support assemblies 50 can initially contact various surfaces and objects, such as a hand, a tabletop, or the ground. When the linkage assembly 40 is subjected to a force in the direction of the air outlet module 20 through various means, such as a user's hand pushing up on the linkage assembly 40, or the support module 30 abutting against a surface to be supported and the user pressing down on the air outlet device 20a, the surface to be supported exerts a force on the linkage assembly 40 in the direction of the air outlet module 20. This embodiment and the following description will only be schematically described using the linkage component 40 abutting against the surface to be supported. From the above description, it can be seen that since the lower end of the linkage component 40 is more protruding, 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 in the direction of the surface to be supported. That is, when downward pressure is applied, the linkage component 40 can be moved upward in the direction close to the air outlet module 20. When the linkage component 40 moves upward, it can drive the multiple support components 50 to rotate synchronously in the direction away from each other, so that the support module 30 is in an expanded state, and the multiple support components 50 are supported on 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 the air outlet device 20a to achieve expansion, without the need for additional control of the linkage component 40, which can further reduce the user's operating difficulty.

[0056] It is worth noting that in this embodiment, the linkage component 40 is initially in contact with the surface to be supported. As the linkage component 40 rises and the multiple support components 50 are unfolded, the multiple support components 50 can also be supported on 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 are supported on the surface to be supported, and the linkage component 40 is separated from the surface to be supported.

[0057] When the support assemblies 50 need to be combined, the linkage assembly 40 can be moved downward in a direction away from the air outlet module 20 to combine and retract the multiple support assemblies 50. Alternatively, one or a small number of support assemblies 50 can be individually controlled to combine and retract, thereby driving the linkage assembly 40 to move downward in a direction away from the air outlet module 20, and then driving the other multiple support assemblies 50 to combine and retract through the linkage assembly 40. Therefore, whether deploying or combining, there is no need to control the movement of multiple support assemblies 50 one by one. Only the linkage assembly 40 needs to be moved to achieve deployment and combination of multiple support assemblies 50.

[0058] In summary, based on the realization of the stand-up dual-purpose fan 1, this embodiment does not require the multiple support assemblies 50 to rotate in sequence during the process of expanding and merging the support assemblies 50. Through the cooperation of the linkage assembly 40, it is only necessary to control the movement of the linkage assembly 40 separately, thereby synchronously driving the multiple support assemblies 50 to expand and merge, reducing the difficulty of user operation.

[0059] It is worth noting that the air outlet device 20a can function as the smallest vending unit, and thus the air outlet device 20a can serve as a standalone protected object. In this case, the present embodiment provides a single air outlet device 20a. The air outlet device 20a includes an air outlet module 20 and a support module 30, which are connected to each other. The air outlet module 20 is configured to blow air outward. The support module 30 has an expanded state and a collapsed state. The support module 30 includes a linkage assembly 40 and a plurality of support assemblies 50. The plurality of support assemblies 50 are arranged circumferentially around the linkage assembly 40 and are all connected to the linkage assembly 40. When the support module 30 is in the collapsed state, at least a portion of the linkage assembly 40 protrudes from the plurality of support assemblies 50 in a direction away from the air outlet module 20. When the linkage assembly 40 is subjected to a force acting in the direction of the air outlet module 20, the linkage assembly 40 moves toward the air outlet module 20, driving the plurality of support assemblies 50 to rotate synchronously away from each other, thereby enabling the support module 30 to be in the expanded state and the plurality of support assemblies 50 to be supported on the surface to be supported.

[0060] Subsequently, this embodiment can also provide a fan 1 composed of an air outlet device 20a and a base module 10. The fan 1 provided in this embodiment includes a base module 10 and the air outlet device 20a provided in the above embodiment of this application. The base module 10 is used to be supported on the ground, and the air outlet device 20a is detachably connected to the base module 10. When the air outlet device 20a is connected to the base module 10, the support module 30 is in a merged state and at least part of the support module 30 is arranged in the base module 10, and at least part of the air outlet module 20 is arranged outside the base module 10.

[0061] Please refer again Figure 6-Figure 7 In this embodiment, the support module 30 also includes a shell assembly 60 connected to the air outlet module 20, and the linkage assembly 40 is arranged on the side of the shell assembly 60 away from the air outlet module 20. Each support assembly 50 includes a support member 51 and a connecting member 52. The support member 51 is rotatably connected to the shell assembly 60, and one end of the connecting member 52 is rotatably connected to the support member 51, and the other end is rotatably connected to the linkage assembly 40.

[0062] In the process of unfolding the support module 30, the linkage assembly 40 moves in the direction close to the shell assembly 60, the other end of the connecting member 52 rotates relative to the linkage assembly 40, one end of the connecting member 52 rotates relative to the support member 51, and the support member 51 rotates relative to the shell assembly 60, thereby causing the support member 51 to rotate in the direction away from the linkage assembly 40.

[0063] During the merging process of the support module 30, the linkage assembly 40 moves in the direction away from the shell assembly 60, the other end of the connecting member 52 rotates in the opposite direction relative to the linkage assembly 40, one end of the connecting member 52 rotates in the opposite direction relative to the support member 51, and the support member 51 rotates in the opposite direction relative to the shell assembly 60, thereby causing the support member 51 to rotate in the direction close to the linkage assembly 40.

[0064] In addition to the above-mentioned components, the support module 30 also includes a shell assembly 60. The shell assembly 60 is connected to the air outlet module 20, and some components of the air outlet module 20 may also be arranged in the shell assembly 60. The linkage assembly 40 is arranged on the side of the shell assembly 60 away from the air outlet module 20, that is, the linkage assembly 40 is arranged below the shell assembly 60. Each support assembly 50 includes a support member 51 and a connecting member 52, wherein the support member 51 is mainly used to support the surface to be supported in the unfolded state, thereby playing a supporting role, and the support member 51 is rotatably connected to the shell assembly 60. The connecting member 52 mainly serves to connect the support member 51 and the linkage assembly 40, such as one end of the connecting member 52 is rotatably connected to the support member 51, and the other end is rotatably connected to the linkage assembly 40.

[0065] With the above arrangement, during the deployment of the support module 30, when downward pressure is applied to the linkage member, the linkage assembly 40 moves upward in a direction approaching the housing assembly 60, the other end of the connector 52 rotates relative to the linkage assembly 40, and one end of the connector 52 rotates relative to the support member 51, causing the support member 51 to rotate relative to the housing assembly 60, thereby causing the support member 51 to rotate outward in a direction away from the linkage assembly 40 and deploy. During the closure of the support module 30, the linkage assembly 40 can be pulled downward to move downward in a direction away from the housing assembly 60, the other end of the connector 52 rotates in the opposite direction relative to the linkage assembly 40, and one end of the connector 52 rotates in the opposite direction relative to the support member 51, causing the support member 51 to rotate in the opposite direction relative to the housing assembly 60, thereby causing the support member 51 to rotate inward in a direction approaching the linkage assembly 40 and retract.

[0066] In summary, through the cooperation among the linkage assembly 40 , the support member 51 , and the connecting member 52 , the structure is simple, and the expansion and merging of the support member 51 can be achieved.

[0067] Optionally, a button 53 may be provided on one of the supports 51, and the button 53 may be used to lock the air outlet device 20a when the air outlet device 20a is installed on the base module 10. When the air outlet device 20a needs to be taken out, the button 53 may be pressed to unlock the air outlet device 20a and then the air outlet device 20a may be taken out.

[0068] Please refer to Figure 7-Figure 8 , Figure 8 for Figure 6A cross-sectional schematic diagram of the support module is shown. In this embodiment, the support member 51 includes a side wall 511 and a bottom wall 512 that is bent and connected to the side wall 511. The side wall 511 is rotatably connected to the housing assembly 60 and one end of the connecting member 52. A first latch portion 4000 is provided on the side of the linkage assembly 40 facing away from the housing assembly 60, and a second latch portion 5120 is provided on the bottom wall 512.

[0069] When the support module 30 is in the merged state, the bottom wall 512 is arranged on the side of the linkage assembly 40 away from the shell assembly 60, and the first snap-fit ​​portion 4000 and the second snap-fit ​​portion 5120 cooperate with each other to enable the support member 51 to be snap-connected to the linkage assembly 40.

[0070] The support member 51 is composed of a sidewall 511 and a bottom wall 512. The bottom wall 512 is bent and connected to the sidewall 511, giving the support member 51 an L-shape. The sidewall 511 is rotatably connected to the housing assembly 60 and one end of the connecting member 52. A first latching portion 4000 is provided on the side of the linkage assembly 40 facing away from the housing assembly 60, that is, below the linkage assembly 40. A second latching portion 5120 is correspondingly provided above the bottom wall 512.

[0071] When the support module 30 is in the combined state, the side walls 511 of the multiple support members 51 can be arranged to form a circle. In this case, the bottom wall 512 is located on the side of the linkage assembly 40 facing away from the housing assembly 60, that is, the bottom wall 512 is located below the linkage assembly 40. Therefore, by cooperating with the first snap-fit ​​portion 4000 and the second snap-fit ​​portion 5120, the support members 51 can be snap-fitted to the linkage assembly 40, thereby improving the stability of the support members 51 in the combined state and preventing them from moving arbitrarily. The first snap-fit ​​portion 4000 includes one of a snap and a slot, and the second snap-fit ​​portion 5120 includes the other of the snap and slot. This embodiment is schematically described using the first snap-fit ​​portion 4000 as a snap and the second snap-fit ​​portion 5120 as a slot.

[0072] In summary, by designing the support member 51 to be L-shaped, the bottom wall 512 can be snap-connected with the linkage assembly 40 when the support module 30 is in the combined state, thereby improving the stability of the support member 51 .

[0073] Optionally, a first limiting portion 513 is provided on one side of the sidewall 511 of the support member 51, and a second limiting portion 514 is provided on the other side of the sidewall 511. When the support module 30 is in the combined state, the first limiting portion 513 of each of the plurality of support members 51 arranged in an annular manner cooperates with the second limiting portion 514 of the adjacent support member 51 to further limit the rotation of the support member 51 and further improve stability. The first limiting portion 513 includes one of a limiting block and a limiting hole, and the second limiting portion 514 includes the other of a limiting block and a limiting hole.

[0074] Please refer to Figure 9, Figure 9 for Figure 8 A partial enlarged view of the support module is shown. In this embodiment, the linkage assembly 40 includes a bottom shell 41 and an end cover 42 mounted on the bottom shell 41. The bottom shell 41 is provided with a first latch portion 4000. The end cover 42 is rotatably connected to the other end of the connector 52. The bottom shell 41 can move relative to the end cover 42 along its axial direction. When the support module 30 is in the merged state, the bottom shell 41 can abut against the surface to be supported.

[0075] In which, during the unfolding process of the support module 30, when pressure is applied to the bottom shell 41 along the direction of the supported surface, the bottom shell 41 moves relative to the end cover 42 in the direction close to the shell assembly 60, so that the first snap-fit ​​portion 4000 is separated from the second snap-fit ​​portion 5120. The bottom shell 41 can also move with the end cover 42 in the direction close to the shell assembly 60, thereby causing multiple support assemblies 50 to rotate synchronously in the direction away from each other.

[0076] The linkage assembly 40 is composed of a bottom shell 41 provided at the bottom and an end cover 42 provided at the top. The bottom shell 41 is provided with the first snap-fit ​​portion 4000 mentioned above. The end cover 42 is installed at the opening above the bottom shell 41. The end cover 42 is rotatably connected to the other end of the connecting member 52. In addition, the bottom shell 41 and the end cover 42 are not fixedly connected. The bottom shell 41 and the end cover 42 are movably connected. The bottom shell 41 can move relative to the end cover 42 along its axial direction. When the support module 30 is in the merged state, the bottom shell 41 abuts against the surface to be supported. Optionally, an abutment portion 410 is protruding from the side of the bottom shell 41 facing away from the air outlet module 20. The abutment portion 410 protrudes from the support member 51, so that the protruding abutment portion 410 can abut against the surface to be supported.

[0077] Based on the above structure, during the deployment of the support module 30, when the air outlet device 20a is pressed downward, that is, when the bottom shell 41 is pressed downward along the surface to be supported, the surface to be supported exerts an upward reaction force on the bottom shell 41, causing the bottom shell 41 to move upward relative to the end cover 42 in a direction closer to the housing assembly 60. When the bottom shell 41 moves upward, the first latch portion 4000 and the second latch portion 5120 are separated, and the latched state is achieved, allowing the support member 51 to rotate. Furthermore, the bottom shell 41 can also move with the end cover 42 in a direction closer to the housing assembly 60, so that, as mentioned above, the other end of the connecting member 52 rotates relative to the end cover 42, one end of the connecting member 52 rotates relative to the support member 51, and the support member 51 rotates relative to the housing assembly 60, thereby causing the multiple support members 51 to rotate synchronously in a direction away from each other.

[0078] In summary, by enabling the bottom shell 41 to move relative to the end cover 42, during the unfolding process, the first snap portion 4000 can be separated from the second snap portion 5120 first, and then the support member 51 can be rotated without manual unlocking, further reducing the difficulty of operation.

[0079] In this embodiment, the bottom shell 41 is provided with an abutment portion 411, with a distance between the abutment portion 411 and the end cap 42. When pressure is applied to the bottom shell 41 in the direction of the supported surface, the bottom shell 41 moves a first distance relative to the end cap 42 toward the housing assembly 60, and the first latch portion 4000 separates from the second latch portion 5120. When the bottom shell 41 moves a second distance relative to the end cap 42 toward the housing assembly 60, the abutment portion 411 abuts the end cap 42, thereby causing the bottom shell 41 to move the end cap 42. The first distance is smaller than the second distance.

[0080] The bottom shell 41 may be provided with a stopper 411 protruding toward the end cap 42. When the bottom shell 41 is not subjected to the rebound force of the surface to be supported, a gap can be controlled between the stopper 411 and the end cap 42. Thus, when pressure is applied to the bottom shell 41 in the direction of the surface to be supported, due to the gap between the stopper 411 and the end cap 42, the bottom shell 41 will first move upward relative to the end cap 42 in a direction approaching the housing assembly 60. When the bottom shell 41 moves a first distance, the first latch portion 4000 and the second latch portion 5120 separate as described above, releasing the locked state of the support member 51. When the bottom shell 41 continues to move upward and moves to a second distance greater than the first distance, the stopper 411 abuts the end cap 42. Therefore, when the bottom shell 41 subsequently moves upward, it can drive the end cap 42 to move upward as well, thereby causing the bottom shell 41 to drive the end cap 42 to move, and then utilizing the end cap 42 to deploy the support member 51.

[0081] Please refer to Figure 9-10 , Figure 10 This is an exploded schematic diagram of the bottom housing and end caps in one embodiment of the present application. In this embodiment, the linkage assembly 40 further includes an elastic member 43 disposed within the bottom housing 41. The end cap 42 is provided with a guide portion 420. The elastic member 43 is sleeved within the guide portion 420 and connects the end cap 42 to the bottom housing 41 at opposite ends. The bottom housing 41 is provided with a through hole 412 corresponding to the guide portion 420.

[0082] When the bottom shell 41 moves relative to the end cover 42 in a direction toward the housing assembly 60, the elastic member 43 is compressed, and the guide portion 420 protrudes from the bottom shell 41 through the through hole 412. When the bottom shell 41 is separated from the support surface, the compressed elastic member 43 can drive the bottom shell 41 to move away from the housing assembly 60.

[0083] The linkage assembly 40 may further include an elastic member 43, which may be disposed within the bottom shell 41, with one end of the elastic member 43 connected to the end cap 42 and the other end connected to the bottom shell 41. When the bottom shell 41 moves upward relative to the end cap 42 in a direction approaching the housing assembly 60, the elastic member 43 is compressed, thereby placing the elastic member 43 in a compressed state. When the air outlet device 20a is lifted to separate the bottom shell 41 from the support surface, or when the bottom shell 41 separates from the support surface as the bottom shell 41 moves upward and the support member 51 supports the support surface, the compressed elastic member 43 can drive the bottom shell 41 to move downward in a direction away from the housing assembly 60, returning the bottom shell 41 to its initial position.

[0084] Furthermore, a guide portion 420 is provided within the end cap 42. The elastic member 43 is sleeved within the guide portion 420 to provide a mounting base for the elastic member 43. Furthermore, a through hole 412 is provided in the bottom shell 41 to correspond to the guide portion 420. When the bottom shell 41 moves upward relative to the end cap 42 in a direction toward the housing assembly 60, the guide portion 420 protrudes from the bottom shell 41 through the through hole 412, thereby providing guidance for the movement of the bottom shell 41.

[0085] Please refer to Figure 8 、 Figure 10-11 , Figure 11 for Figure 1 A partial cross-sectional schematic diagram of a stand fan is shown. In this embodiment, the support module 30 further includes a housing assembly 60 connected to the air outlet module 20. The linkage assembly 40 is disposed on a side of the housing assembly 60 facing away from the air outlet module 20. The air outlet module 20 includes a first electrical connection terminal 61 disposed within the housing assembly 60. The linkage assembly 40 has a through hole 400. When the support module 30 is in a combined state, the multiple support assemblies 50 are arranged to form a receiving space 500. The base module 10 includes a base 11, a support rod 12, and a second electrical connection terminal 13. The base 11 is used for supporting the ground. The support rod 12 is disposed on the base 11, and the second electrical connection terminal 13 is disposed within the support rod 12.

[0086] When the air outlet device 20 a is connected to the base module 10 , the end of the support rod 12 passes through the linkage assembly 40 through the through hole 400 , and the first electrical connection end 61 is connected to the second electrical connection end 13 in the receiving space 500 .

[0087] The air outlet module 20 is provided with a first electrical connection terminal 61 located within the housing assembly 60. The first electrical connection terminal 61 is used to connect to an external power source to provide power to the air outlet module 20. In this embodiment, a through hole 400 is provided in the linkage assembly 40 along its axial direction, that is, a through hole 400 is provided in the end cover 42 and the bottom shell 41, providing a foundation for the subsequent support rod 12 and the housing assembly 60 to penetrate the linkage assembly 40.

[0088] When the support components 50 are in a combined state, multiple support components 50 are arranged to form a receiving space 500. The base module 10 includes a base 11, a support rod 12, and a second electrical connection end 13. The base 11 is circular and supported on the ground. The rod-shaped support rod 12 is arranged on the base 11 to provide a certain height for the air outlet device 20a so that it can become a vertical electric fan.

[0089] In this embodiment, a second electrical connection terminal 13 can be added to the support rod 12. When the support assembly 50 is in the combined state and mounted on the base module 10 with the air outlet module 20, the support module 30 is disposed within the support rod 12 of the base module 10. The end of the support rod 12 then passes through the linkage assembly 40 via the through hole 400, and the first electrical connection terminal 61 connects to the second electrical connection terminal 13 within the receiving space 500. This allows the second electrical connection terminal 13 to provide power to the air outlet module 20, eliminating the need for additional components to connect to the first electrical connection terminal 61 and simplifying the structure. Furthermore, concealing the second electrical connection terminal 13 within the support rod 12 improves the appearance and performance of the fan 1.

[0090] Please refer to Figure 12 , Figure 12 for Figure 7 A cross-sectional schematic diagram of the support module is shown. In this embodiment, the housing assembly 60 includes a housing 62 and a protrusion 63 disposed on the side of the housing 62 facing away from the air outlet module 20. The first electrical connection end 61 is disposed within the protrusion 63. When the support module 30 is in the deployed state, the end of the protrusion 63 and the first electrical connection end 61 protrude from the linkage assembly 40. The first electrical connection end 61 is configured to connect to the third electrical connection end.

[0091] The shell assembly 60 is composed of a shell 62 and a protrusion 63 on the side of the shell 62 facing away from the air outlet module 20. That is, a protrusion 63 is further extended from the bottom of the shell 62, and the first electrical connection end 61 can be arranged in the protrusion 63. When the support module 30 is in the expanded state, the linkage assembly 40 will move upward toward the shell assembly 60. When it moves to the expanded state, the protrusion 63 can pass through the linkage assembly 40 through the through hole 400, and the end of the protrusion 63 and the first electrical connection end 61 can protrude from the linkage assembly 40. In other words, the first electrical connection end 61 can be exposed. In this way, in the expanded state, a third electrical connection end can be connected to the first electrical connection end 61 via an external source, thereby utilizing the third electrical connection end to provide electrical energy to the air outlet module 20.

[0092] Please refer to Figure 13 , Figure 13This is a cross-sectional schematic diagram of a support module in another embodiment of the present application. In this embodiment, when the support module 30 is in the deployed state, the surface of the protrusion 63 proximal to the support surface is flush with the surfaces of the multiple support assemblies 50 proximal to the support surface. The protrusion 63 protrudes from the sidewall 511 of the linkage assembly 40 and defines a connection hole 630. The third electrical connection terminal connects to the first electrical connection terminal 61 through the connection hole 630.

[0093] When the support module 30 is in the deployed state, the end of the protrusion 63 protrudes beyond the linkage assembly 40, meaning that the end of the protrusion 63 is closer to the supported surface than the linkage assembly 40. Therefore, the surface of the protrusion 63 near the supported surface can be flush with the surfaces of the multiple support assemblies 50 near the supported surface. In other words, the lower surface of the protrusion 63 is flush with the lower surface of the support assembly 50 in the deployed state, allowing the support assembly 50 and the protrusion 63 to jointly support the supported surface, thereby enhancing the support effect. Furthermore, because the protrusion 63 supports the supported surface, the linkage assembly 40 can be separated from the supported surface, which also facilitates the aforementioned return of the bottom shell 41 to its original position under the action of the elastic member 43.

[0094] Because the protrusion 63 abuts the support surface, it blocks the opening below the protrusion 63, thereby blocking the first electrical connection end 61. Furthermore, in this embodiment, a connection hole 630 may be provided on the side wall 511 of the protrusion 63 protruding from the linkage assembly 40, through which the third electrical connection end is connected to the first electrical connection end 61. In other words, the third electrical connection end is connected to the first electrical connection end 61 via the side wall 511 of the protrusion 63, simplifying the connection between the first and third electrical connection ends.

[0095] Please refer to Figure 14 , Figure 14 This is a cross-sectional schematic diagram of a support module in another embodiment of the present application. In this embodiment, the support module 30 further includes a housing assembly 60 connected to the air outlet module 20. The linkage assembly 40 is disposed on a side of the housing assembly 60 facing away from the air outlet module 20. The housing assembly 60 includes a housing 62 and a protrusion 63 disposed on the housing 62 facing away from the air outlet module 20. When the support module 30 is in the deployed state, the protrusion 63 abuts the linkage assembly 40.

[0096] The positional relationship between the linkage assembly 40 and the housing assembly 60, as well as the housing 62 and protrusion 63 within the housing assembly 60, has been described in detail above and will not be further elaborated upon in this embodiment. In this embodiment, the linkage assembly 40 does not have a through-hole 400. Therefore, during the deployment of the support module 30, the linkage assembly 40 will move upward toward the housing assembly 60. When the support module 30 is deployed, the protrusion 63 abuts against the linkage assembly 40, preventing further upward movement and terminating the movement.

[0097] Optionally, the support assembly 50 and the linkage assembly 40 may be supported together on the surface to be supported, or only the support assembly 50 may be supported on the surface to be supported.

[0098] Optionally, since the linkage assembly 40 does not have a through hole 400, the first electrical connection end 61 is not arranged in the protrusion 63 in this embodiment, but is arranged in the shell 62. A hole can be opened on the side wall 511 of the shell 62. Whether it is a desktop fan or a standing fan, other electrical connection ends can be connected to the first electrical connection end 61 through the hole.

[0099] This application has introduced various specific structures of the fan in detail above. Next, this application will continue to introduce the dimensional relationship between the linkage assembly and the support assembly in the support module. The following will simplify the various components in the support module into a straight-link mechanism model. The dimensions of each part are shown in the figure below. Please refer to Figure 15-17 , Figure 15 This is a schematic diagram of a support module in an expanded state in one embodiment of the present application. Figure 16 This is a schematic diagram of another embodiment of the present application when the support module is in an expanded state. Figure 17 This is a schematic diagram of a supporting module in an embodiment of the present application when it is in a combined state.

[0100] in, Figure 15-17 is a simplified schematic diagram of the support module. First, r1 is the distance from the upper end of the support member to the center axis of the support module ( Figure 15-17 (indicated by the vertical dashed line in the figure). l1 is the distance from the upper end of the support member to the connection between the support member and the connector. l2 is the distance from the connection between the support member and the connector to the lower end of the support member. l3 is the length of the connector. r2 is the distance from the connection between the connector and the linkage assembly to the central axis of the support module. h is the distance the linkage assembly protrudes downward. θ1 is the angle between the support member and the horizontal plane. θ2 is the angle between the connector and the horizontal plane. α is the angle between the connector and the support member when in the combined state.

[0101] like Figure 15 As shown, in order to ensure that the support surface of the support member is flush with the middle bottom of the linkage assembly in the unfolded state, the structural dimensions should meet the following requirements:

[0102] l1·cosθ1+r1=l3·cosθ2+r2

[0103] and

[0104] l2·sinθ1=h+l3·sinθ2。

[0105] like Figure 16As shown, in particular, if the connecting member is parallel to the supported surface in the unfolded state, the support member can reach the maximum opening angle and minimum height. At this time, the structure has the greatest stability, and the structural dimensions should meet the following requirements:

[0106] l1·cosθ1+r1=l3+r2

[0107] and

[0108] l2·sinθ1=h.

[0109] like Figure 17 As shown, in the combined state, each structural dimension should meet the following requirements:

[0110] l3·sinα <l2<l3·sinα+h,

[0111] In order to ensure that the support member can be opened by pushing the linkage assembly in the combined state, α should be greater than 0°.

[0112] Please refer to Figures 18-20 , Figure 18 This is a schematic diagram of a support module in another embodiment of the present application when it is in an expanded state. Figure 19 This is a schematic diagram of a support module in an expanded state in yet another embodiment of the present application. Figure 20 This is a schematic diagram of another embodiment of the present application when the support modules are in a combined state.

[0113] If we consider an actual structural feature of the support module, it can be simplified to the connecting rod structure shown in the figure below, where d1 is the distance from the upper end of the support member to the connection between the support member and the shell assembly. r1 is the distance from the connection between the support member and the shell assembly to the center axis of the support module ( Figures 18-20 (shown by the vertical dotted line in the figure). l1 is the distance from the upper end of the support member to the connection between the support member and the connecting member. l2 is the distance from the connection between the support member and the connecting member to the lower end of the support member. d3 is the distance from the lower end of the support member to the contact between the support member and the surface to be supported. d2 is the distance from the left end of the connecting member to the connection between the connecting member and the support member. l3 is the length of the connecting member. r2 is the distance from the connection between the connecting member and the linkage component to the central axis of the support module. h is the distance that the linkage component protrudes downward. θ1 is the angle between the support member and the horizontal plane. θ2 is the angle between the connecting member and the horizontal plane. α is the angle between the connecting member and the vertical plane in the combined state.

[0114] like Figure 18 As shown, in order to ensure that the support surface of the support member is flush with the middle bottom of the linkage assembly in the unfolded state, the structural dimensions should meet the following requirements:

[0115] r1+d1+l1·cosθ1=r2+l3·cosθ2+d2·sinθ1

[0116] and

[0117] l2·sinθ1+d3=d2·cosθ1+l3·sinθ2+h.

[0118] like Figure 19 As shown, in particular, if the connecting member is parallel to the supported surface in the unfolded state, the support member can reach the maximum opening angle and minimum height. At this time, the structure has the greatest stability, and the structural dimensions should meet the following requirements:

[0119] r1+d1+l1·cosθ1=r2+l3+d2·sinθ1

[0120] and

[0121] l2·sinθ1+d3=d2·cosθ1+h.

[0122] like Figure 20 As shown, in the combined state, each structural dimension should meet the following requirements:

[0123] l3·sinα <l2+d3·sinθ1<l3·sinα+h,

[0124] In order to ensure that the support member can be opened by pushing the linkage assembly in the combined state, α should be greater than 0°.
