Description

Technical Field

[0001] This utility model relates to the field of fan technology, and more specifically, to a fan structure. Background Technology

[0002] Currently, fans have become an essential item in hot weather. Standing fans are too bulky to carry around, while portable fans have smaller fan heads and limited functionality, only meeting the portability needs of travel. They are not very effective at cooling down and circulating air, and cannot balance airflow and size. Although there are fans that can be used as both standing and table fans, switching between the two forms usually requires screw-on installation, which is quite cumbersome. Utility Model Content

[0003] The present invention aims to at least solve the technical problem that the operation of switching modes of existing dual-purpose fans is cumbersome in the prior art or related technologies.

[0004] In view of this, an embodiment of the present invention provides a fan structure.

[0005] To achieve the above objectives, embodiments of this utility model provide a fan structure, including: a fan head structure; a support leg assembly movably connected to the fan head structure, the support leg assembly including a connecting body and multiple support leg bodies, at least one support leg body being rotatable relative to the connecting body; a base structure, the base structure having a support rod, one end of the support rod having a connecting portion; wherein, when the support leg assembly is in a retracted state, the connecting portion is detachably connected to the support leg assembly.

[0006] The fan structure proposed in this utility model mainly utilizes a modular structure to achieve a balance between airflow and portability. This reduces the difficulty of form-switching operations and expands the applicability range while allowing for use in multiple scenarios. Specifically, the fan structure includes a fan head structure, a support frame, and a base structure. The fan head structure, as the main working part of the fan, is located at the top of the entire fan structure. The fan head structure includes key components such as fan blades and a motor, providing airflow. The fan head structure is movably connected to the support frame, allowing for flexible adjustment when used independently.

[0007] The support leg assembly includes a connecting body and support leg bodies that can rotate relative to each other. The connecting body is mainly used to connect the fan head structure and multiple support leg bodies. By restricting at least one support leg to rotate relative to the connecting body, the function of unfolding or retracting is achieved. When unfolded, the support leg structure is at a certain tilt angle, cooperating with each other to form a stable support structure. It can be understood that the support leg structure can achieve multiple angle support states (such as a triangular structure) through rotation, ensuring the stability of the fan. When not in use, the support leg structure can be retracted and fit snugly with the connecting body, facilitating transportation and storage.

[0008] It is understood that the support leg assembly is located at the bottom of the fan head structure and is movably connected to it. In the retracted state, the support leg assembly is fixed to the support rod of the base structure through the connecting part. In one configuration, the fan head structure and the support leg assembly can be used independently, i.e., the support leg assembly supports the fan head structure. In another configuration, the support leg assembly is assembled onto the connecting part, thereby utilizing the base structure to support the fan head structure. The connecting part allows for quick installation or removal of the support leg assembly, facilitating the independent use of the fan head structure.

[0009] The fan supports multiple usage modes (such as desktop or floor-standing) thanks to the retractable support legs. The base structure is located at the bottom of the fan, forming a vertical connection with the support legs and fan head. The connector on the support rod is directly connected to the support legs when they are in the retracted state.

[0010] Furthermore, the movable connection between the fan head structure and the support frame allows the fan head structure to oscillate left and right and adjust its angle up and down to meet different air delivery needs.

[0011] In some technical solutions, optionally, at least one support body can rotate relative to the fan head structure, and multiple support bodies are stacked when the support leg assembly is in a retracted state; wherein the shape of the stacked multiple support bodies is adapted to the shape of the connecting part.

[0012] In this technical solution, at least one support foot body is restricted to rotate relative to the fan head structure. Specifically, the bottom end of this support foot body is fixed to the support body via a pivot or hinge, but it can rotate a certain angle around the axis of the connecting body. During rotation, the support foot assembly can be easily unfolded or retracted. When fan support is needed, the rotating support foot body can be easily unfolded, providing stable support. When retracted, the rotating support foot body can be easily stacked with other support foot bodies, avoiding excessive space occupation and achieving a compact storage effect.

[0013] It's understandable that rotating the support legs allows you to adjust their angle and ensure fan head stability. When unfolded, the angle of the support legs affects the fan's support force; therefore, rotating them adjusts the support angle to ensure even force distribution and prevent the fan from tilting or becoming unstable.

[0014] When the support leg assembly is in its stowed state, the connecting part and the multiple stacked support legs of the support leg assembly are tightly connected through shape adaptation, ensuring the stable fixation of the support leg assembly when not in use. When the support leg assembly is unfolded, the connecting part provides support, ensuring a firm and reliable connection between the support leg and the base structure.

[0015] The connecting part and the support leg assembly are detachably connected, so that when the fan head structure needs to be used alone, the support leg assembly can be easily detached from the support rod along with the fan head structure, and the support leg assembly can be unfolded for use alone. When not in use, the support leg assembly can be quickly stored back into the connecting part and fixed.

[0016] In some technical solutions, the solution may optionally include: a limiting hole provided on at least one support body, the limiting hole extending in an arc shape around a first axis of rotation of the support body relative to the connecting body; and a fixing member provided at one end of the plurality of support bodies away from the fan head structure, the fixing member including a limiting rod extending into the limiting hole of at least one support body.

[0017] In this technical solution, a limiting hole is provided on the support body, which, under the action of the fixing component and the limiting hole, can limit the rotation angle of the support body. Specifically, the limiting hole extends in an arc shape around the first axis of rotation of the support body relative to the connecting body, so that the rotation angle of the support body can be limited, ensuring that the support body will not rotate arbitrarily or exceed the predetermined angle.

[0018] By using limiting holes and fasteners, the rotation of the support legs is restricted, preventing excessive extension or retraction of the support legs and ensuring stable operation of the fan at different heights and angles. This also helps maintain proper connection between the support legs and the base structure and support rods.

[0019] The fixing element is located at the end of the multiple support legs furthest from the fan head structure. The fixing element includes a limiting rod that extends into a limiting hole in one or more support legs. When the support legs are unfolded, the limiting rod extends into the limiting hole to ensure the angle of the legs is stable and to prevent the legs from rotating or loosening during use. When the support leg assembly is in the retracted state, the limiting rod securely locks the multiple support legs together. The limiting rod, through its connection with the limiting hole, prevents the support legs from loosening or shifting during storage, ensuring that the legs are tightly stacked in the retracted state.

[0020] In some technical solutions, optionally, the number of support legs is three, and when the support leg assembly is in the unfolded support state, the included angle between the projections of two support legs on the cross section of the first axis is 120°.

[0021] In this technical solution, the support assembly comprises three support bodies. When the support assembly is deployed, the three support bodies are evenly distributed on a horizontal plane, forming a stable triangular support structure that provides excellent stability when independently supporting the fan. On the cross-section of the first axis, by defining the projected angle between two support bodies as 120°, when the support bodies are deployed, the angle between two adjacent support bodies is also 120°, forming an equilateral triangular support structure (each angle is 120°). This ensures that the relative angles of the support bodies are symmetrical when deployed, guaranteeing the balance and stability of the support structure.

[0022] In some technical solutions, optionally, the extension direction of the support rod is parallel to and does not coincide with the extension direction of the first axis, the extension direction of the connecting part is not parallel to the extension direction of the first axis; and / or the fan head structure is located on one side of the base structure in the height direction, and the first axis extends in the height direction.

[0023] By restricting the relative positional relationship between the support rod and the first axis, that is, the extension direction of the support rod is parallel to and does not coincide with the extension direction of the first axis, the extension direction of the support rod is parallel to the first axis, but there is a spatial displacement between the two, that is, the two do not coincide. The support rod is parallel to and separate from the first axis, making the overall center of gravity of the fan more balanced and avoiding structural instability problems that may be caused by overlapping design.

[0024] Furthermore, by implementing a separate design, space can be provided for the corresponding structure or the accommodation of wires, thus avoiding interference between functional components.

[0025] By limiting the extension direction of the connecting part to be non-parallel to the extension direction of the first axis, that is, the extension direction of the connecting part is inclined to the first axis, forming a certain angle, the connecting part, as the intersection of other fan components (such as support rods, feet, etc.), undertakes the functions of connection and support, so that the connecting part can better distribute the force from the fan head and support rod, and improve the mechanical stability of the overall structure.

[0026] Meanwhile, the inclined design of the connecting part provides greater movement space for the support rod to rotate and the fan head to adjust, ensuring flexibility in angle adjustment. The non-parallel design avoids the stacking of spatial structures, allowing each functional module to be distributed independently and improving the scalability of the design.

[0027] Furthermore, by restricting the fan head structure to one side of the base structure in the height direction, the first axis extends along the height direction, the fan head structure is located at the top of the fan, and the base structure is located at the bottom, with both distributed along the height direction.

[0028] The first axis runs through the height of the fan and serves as the main reference axis. Its distribution along the height makes the functions of the upper and lower structures of the fan clearly distinguished, with the top focusing on airflow output and the bottom focusing on support and stability.

[0029] In some technical solutions, optionally, it also includes: a first protrusion, provided at one end of the connecting body facing the base structure, and a limiting groove adapted to the shape of the first protrusion is provided in the connecting part; wherein, the cross-section of the first protrusion is non-circular.

[0030] In this technical solution, by setting a first protrusion and a limiting groove, the distance between the support leg assembly and the connecting part in the stored state can be limited, preventing further rotation. Specifically, the first protrusion is located at the end of the connecting body facing the base structure, that is, at the bottom of the connecting body, near the base structure. The cross-section of the first protrusion is not a simple circle, but rather a non-circular shape, which may be elliptical, square, irregular, or other special geometric shapes. Because the cross-section of the first protrusion is non-circular, it provides a better positioning effect, preventing rotation or displacement between the connecting part and the connecting body.

[0031] The limiting groove is located inside the connecting part and its shape is adapted to the first protrusion. The shape of the limiting groove is precisely matched with the non-circular cross-section of the first protrusion to ensure that the two can be tightly connected. The limiting groove is used to lock the first protrusion, ensure that the connection point between the connecting body and the connecting part is stable, prevent loosening, limit the lateral or rotational movement of the first protrusion, and ensure the structural integrity.

[0032] In some technical solutions, the connecting part is optionally perforated, and a second protrusion is provided at one end of the connecting body facing the base structure. The shape of the second protrusion is adapted to the shape of the connecting part to realize the detachable connection between the connecting part and the support assembly.

[0033] In this technical solution, the connecting part is perforated, and the second protrusion cooperates with the perforated connecting part to form a detachable connection. It can be understood that the connecting part itself is a structure with a hole, possibly circular or other geometrically shaped, used to receive and connect the second protrusion. By inserting the second protrusion, the support rod and the leg assembly can be connected, allowing the user to quickly detach the top fan head structure, enabling the fan head structure to be used independently.

[0034] In some technical solutions, optionally, the support body rotates about a second axis relative to the connecting body, and the second axis is located in the normal plane corresponding to the axis of the connecting part.

[0035] In this technical solution, the support body rotates around the second axis relative to the connecting body, and the second axis is located in the normal plane corresponding to the axis of the connecting part. That is, the second axis and the axis of the connecting part are perpendicular to each other, and there is a non-plane orthogonal positional relationship between the second axis and the axis of the connecting part. The support body rotates around the second axis, so that the support body can swing or unfold freely along the direction of the second axis in the supported state.

[0036] In some technical solutions, optionally, when the support leg assembly is in the retracted state, the support leg body is snapped into connection with the connecting body. The fan structure also includes: an unlocking component, which is provided on the connecting body. The unlocking component is triggered to release the snap-fit ​​between the support leg body and the connecting body.

[0037] In this technical solution, the support base and the connecting body are connected via a snap-fit ​​mechanism. When the fan is folded up, they are connected by this snap-fit. Specifically, the snap-fit ​​design typically uses clips or latching structures to ensure a secure and stable connection between the support base and the connecting body. When the fan is not in use, the support base is tightly secured to the connecting body via the snap-fit, preventing the legs from loosening or falling off and ensuring the fan remains neat and stable during storage. After the snap-fit ​​is released by triggering the unlocking mechanism, the support base can be quickly released and unfolded, facilitating rapid installation or adjustment by the user.

[0038] By placing a unlocking element on the connecting body, the locking relationship between the foot and the connecting body is released. Specifically, the unlocking element may include, but is not limited to, a button, pull ring, knob, or other mechanical triggering device, which the user triggers to release the foot.

[0039] In some technical solutions, optionally, when the support leg assembly is in the retracted state, the outer surface of at least a portion of the support leg body is flush with the outer surface of at least a portion of the support rod; and / or when the support leg assembly is in the extended support state, the ends of the plurality of support leg bodies away from the fan head structure are on the same plane.

[0040] In this technical solution, when the support leg assembly is in the unfolded support state, the ends of multiple support legs away from the fan head structure are on the same plane, ensuring that the support legs can provide stable support.

[0041] Specifically, when the support leg assembly is deployed, the ends of the support legs furthest from the fan head structure will be on the same plane, meaning all support legs form a single plane on the support surface. This ensures even and stable force distribution on the legs, preventing any single leg from bearing excessive pressure and guaranteeing fan stability. Regardless of how the fan's weight is distributed, all legs can share the load.

[0042] Whether the ground where the fan is placed is flat or slightly inclined, the planar design of the support body can effectively distribute the load, allowing the fan to maintain high stability in various environments.

[0043] Furthermore, when the support leg assembly is in the retracted state, a portion of the outer surface of the support leg body will be flush with the outer surface of the support rod. Moreover, the flush outer surface is the surface of the part where the support leg body and the support rod are connected, thereby making the support leg assembly and the support rod form an integrated appearance structure, reducing the appearance of protrusions and grooves, improving both aesthetics and the safety of equipment use.

[0044] Specifically, for the design where the connecting part is hole-shaped and the end of the connecting body facing the base structure has a second protrusion, the circumferential outer surface of part of the support body is flush with the circumferential outer surface of part of the support rod where the connecting part is located.

[0045] For a solution where multiple support legs are stacked when the support leg assembly is in the stowed state, the connecting part is groove-shaped, and the upper surface of the top support leg is flush with the opening of the connecting part.

[0046] In some technical solutions, optionally, the connecting body is provided with a universal joint that is movably connected to the fan head structure.

[0047] In this technical solution, by providing a universal joint on the connecting body that is movably connected to the fan head structure, the position of the fan head structure can be flexibly adjusted through the universal joint, that is, the fan head structure is allowed to swing freely at multiple angles while maintaining a stable connection.

[0048] Additional aspects and advantages of this invention will become apparent in the description that follows, or may be learned by practice of this invention. Attached Figure Description

Detailed Implementation

[0063] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this utility model, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0064] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0065] The following reference Figures 1 to 12 Some embodiments according to the present invention are described.

[0066] like Figure 1 and Figure 5 As shown, this embodiment provides a fan structure 100, which mainly utilizes a modular structure to achieve a balance between airflow and portability, enabling its use in multiple scenarios and expanding its applicability. Specifically, the fan structure 100 includes a fan head structure 102, a support assembly 104, and a base structure 106. The fan head structure 102, as the main working part of the fan, is located at the top of the entire fan structure 100. The fan head structure 102 includes key components such as fan blades and a motor, providing airflow functionality. The fan head structure 102 is movably connected to the support assembly 104, allowing for flexible adjustment when used independently.

[0067] The support leg assembly 104 includes a connecting body 1044 and support leg bodies 1042 that are rotatable relative to each other. The connecting body 1044 is mainly used to connect the fan head structure 102 and multiple support leg bodies 1042. By restricting at least one support leg to rotate relative to the connecting body 1044, the function of unfolding or retracting is achieved. When unfolded, the support leg structure is at a certain tilt angle, cooperating with each other to form a stable support structure. It can be understood that the support leg structure can achieve multiple angle support states (such as a triangular structure) through rotation, ensuring the stability of the fan. When not in use, the support leg structure can be retracted and fit snugly against the connecting body 1044, facilitating transportation and storage.

[0068] It is understood that the support leg assembly 104 is located at the bottom of the fan head structure 102 and is movably connected to it. In the stored state, the support leg assembly 104 is fixed to the support rod 1062 of the base structure 106 through the connecting part 1064. In one configuration, the fan head structure and the support leg assembly can be used independently, that is, the support leg assembly supports the fan head structure. In another configuration, the support leg assembly is assembled onto the connecting part, so that the base structure can be used to support the fan head structure. The connecting part 1064 enables quick installation or removal of the support leg assembly 104, facilitating the independent use of the fan head structure 102.

[0069] The storage function of the support leg assembly 104 supports multiple usage modes (such as desktop or floor-standing). The base structure 106 is located at the bottom of the entire fan and forms a vertical connection with the support leg assembly 104 and the fan head structure 102. The connecting part 1064 on the support rod 1062 is directly connected to the support leg assembly 104 when the support leg assembly 104 is in the stored state.

[0070] Furthermore, the movable connection between the fan head structure 102 and the support assembly 104 allows the fan head structure 102 to oscillate left and right and adjust its angle up and down to meet different air delivery needs.

[0071] When the support leg assembly 104 is stowed, it can be connected to the connecting part 1064 of the support rod 1062 of the base structure 106 to form a complete integrated floor fan. When the support leg assembly 104 is unfolded, it ensures that the fan head structure 102 is evenly stressed when used independently, preventing it from tipping over. Even stress distribution is achieved through the tilt angle and the fixing parts 1084 between the support points, enhancing overall stability.

[0072] Furthermore, the fan head structure 102 can be fixed to the support rod 1062 of the base by a limiting structure to provide stable support.

[0073] In some embodiments, optionally, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, at least one support column 1042 is restricted to rotate relative to the fan head structure 102. Specifically, the bottom end of this support column 1042 is fixed to the support body 1044 via a pivot or hinge, but it can rotate a certain angle around the axis of the support body 1044. During rotation, the support body 104 can be easily unfolded or retracted. When fan support is needed, the rotating support column 1042 can be easily unfolded to provide stable support. When retracted, the rotating support column 1042 can be easily stacked with other support columns 1042, avoiding excessive space occupation and achieving a compact storage effect.

[0074] It is understandable that rotating the support body 1042 can adjust the angle of the support legs, ensuring the stability of the fan head. When unfolded, the angle of the support legs affects the supporting force of the fan, so rotating it can adjust the support angle to ensure even force distribution and prevent the fan from tilting or becoming unstable.

[0075] The shape of the stacked support body 1042 is adapted to the shape of the connecting part 1064. The support body 1042 has a specific geometric shape (such as groove, protrusion, rounded corner, etc.) to ensure that the two are tightly and securely connected to the connecting part 1064.

[0076] When the leg assembly 104 is in the retracted state, the connecting part 1064 and the multiple stacked leg bodies 1042 of the leg assembly 104 are tightly connected through shape adaptation, ensuring the stable fixation of the leg assembly 104 when not in use. When the leg assembly 104 is unfolded, the connecting part 1064 provides support, ensuring a firm and reliable connection between the legs and the base structure 106.

[0077] The connecting part 1064 is detachably connected to the support leg assembly 104, so that when the fan head structure 102 needs to be used alone, the support leg assembly 104 can be easily detached from the support rod 1062 along with the fan head structure 102, and the support leg assembly 104 can be unfolded for use alone. When not in use, the support leg assembly 104 can be quickly stored back into the connecting part 1064 and fixed.

[0078] The design of the support leg assembly 104 allows users to quickly store it when not in use, and it fits tightly with the connector 1064, avoiding cumbersome disassembly operations.

[0079] When in use, the support leg assembly 104 can be quickly extended and connected to the connecting part 1064 to provide stable support.

[0080] The rotation function of at least one support body 1042 provides convenient support angle adjustment, ensuring the stability of the fan under various operating conditions.

[0081] In some embodiments, optionally, a limiting hole 1082 is provided on the support body 1042, which can limit the rotation angle of the support body 1042 under the action of the fixing member 1084 and the limiting hole 1082. Specifically, the limiting hole 1082 extends in an arc shape around the first axis of rotation of the support body 1042 relative to the connecting body 1044, so that the rotation angle of the support body can be limited, ensuring that the support body will not rotate arbitrarily or exceed the predetermined angle.

[0082] The first axis is the axis through which the support leg rotates relative to the connecting body 1044. The arc-shaped design of the limiting hole 1082, combined with this axis, ensures that the rotation of the support leg is limited and does not affect the stability of the fan.

[0083] By using the limiting hole 1082 and the fixing member 1084, the rotation of the support leg is restricted, preventing the support leg body from being over-extended or retracted, and ensuring that the fan operates stably at different heights and angles. This also helps to maintain the correct connection between the support leg and the base structure 106 and the support rod 1062.

[0084] The fastener 1084 is located at the end of the plurality of support bodies 1042 away from the fan head structure 102. For example... Figure 3As shown, the fixing member 1084 includes a limiting rod 1086 that extends into the limiting hole 1082 of one or more support legs 1042. When the support legs 1042 are unfolded, the limiting rod 1086 extends into the limiting hole 1082 to ensure the angle of the support legs is stable and to prevent the support legs from rotating or loosening during use. When the support leg assembly 104 is in the retracted state, the limiting rod 1086 can securely lock multiple support legs 1042 together. The limiting rod 1086, through its connection with the limiting hole 1082, can prevent the support legs from loosening or misaligning during storage, ensuring that the support legs are tightly stacked in the retracted state.

[0085] The fastener 1084 is located at the end of the support leg assembly 104 away from the fan head structure 102. The limiting rod 1086 extends into the limiting hole 1082 of the support leg body, forming a mechanical locking structure. The length, shape, and structure of the limiting rod 1086 are matched with the design of the limiting hole 1082 to ensure a secure connection.

[0086] In some embodiments, optionally, such as Figure 4 and Figure 10 As shown, the support assembly 104 includes three support bodies 1042. When the support assembly 104 is in the unfolded support state, the three support bodies are evenly distributed on the horizontal plane to form a stable triangular support structure, which can provide excellent stability when independently supporting the fan.

[0087] On the cross-section of the first axis, as Figure 4 As shown, by limiting the included angle between the projections of the two support pillars 1042 to 120°, when the support pillars are unfolded, the included angle between the two adjacent support pillars 1042 is 120°, thus forming an equilateral triangular support structure (each angle is 120°). This ensures that the relative angles of the support pillars 1042 are symmetrical when unfolded, guaranteeing the balance and stability of the support structure.

[0088] In some embodiments, optionally, such as Figure 2 and Figure 3 As shown, the first protrusion 1102 and the limiting groove 1104 are provided to limit the movement between the support leg assembly 104 and the connecting part 1064 in the stored state, preventing further rotation. Specifically, the first protrusion 1102 is located at the end of the connecting body 1044 facing the base structure 106, that is, at the bottom of the connecting body 1044, near the base structure 106. The cross-section of the first protrusion 1102 is not a simple circle, but a non-circular shape, which may be elliptical, square, irregular, or other special geometric shapes. Because the cross-section of the first protrusion 1102 is non-circular, it provides a better positioning effect and prevents rotation or displacement between the connecting part 1064 and the connecting body 1044.

[0089] The limiting groove 1104 is located inside the connecting part 1064 and its shape is adapted to the first protrusion 1102. The shape of the limiting groove 1104 precisely matches the non-circular cross-section of the first protrusion 1102 to ensure that the two can be tightly joined. The limiting groove 1104 is used to lock the first protrusion 1102, ensuring that the connection point between the connecting body 1044 and the connecting part 1064 is stable, preventing loosening, and restricting the lateral or rotational movement of the first protrusion 1102 to ensure the structural integrity.

[0090] Furthermore, the non-circular design means that the connecting body 1044 and the connecting part 1064 can only be assembled in a specific direction, avoiding reverse connection or incorrect docking.

[0091] In some embodiments, optionally, such as Figure 2 As shown, by restricting the relative positional relationship between the support rod 1062 and the first axis, that is, the extension direction of the support rod 1062 is parallel to and does not coincide with the extension direction of the first axis, the extension direction of the support rod 1062 is parallel to the first axis, but there is a spatial displacement between the two, that is, the two do not coincide. The support rod 1062 is parallel to and separate from the first axis, making the overall center of gravity of the fan more balanced and avoiding structural instability problems that may be caused by overlapping design.

[0092] Furthermore, by implementing a separate design, space can be provided for the corresponding structure or the accommodation of wires, thus avoiding interference between functional components.

[0093] By limiting the extension direction of the connecting part 1064 to be non-parallel to the extension direction of the first axis, that is, the extension direction of the connecting part 1064 is inclined to the first axis, forming a certain angle, the connecting part 1064 serves as the intersection of other fan components (such as the support rod 1062, the support leg assembly 104, etc.), undertaking the functions of connection and support, so that the connecting part 1064 can better disperse the force from the fan head and the support rod 1062, and improve the mechanical stability of the overall structure.

[0094] Meanwhile, the inclined design of the 1064 connecting section provides greater movement space for the support rod rotation and fan head adjustment, ensuring flexibility in angle adjustment. The non-parallel design avoids the stacking of spatial structures, allowing each functional module to be independently distributed and improving the scalability of the design.

[0095] Furthermore, by restricting the fan head structure 102 to one side of the base structure in the height direction, with the first axis extending in the height direction, the fan head structure 102 is located at the top of the fan, while the base structure is located at the bottom, and the two are distributed in the height direction.

[0096] The first axis runs through the height of the fan and serves as the main reference axis. Its distribution along the height makes the functions of the upper and lower structures of the fan clearly distinguished, with the top focusing on airflow output and the bottom focusing on support and stability.

[0097] In some embodiments, optionally, such as Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the connecting portion 1064 is hole-shaped, and the second protrusion 1066 cooperates with the hole-shaped connecting portion 1064 to form a detachable connection. It can be understood that the connecting portion 1064 itself is a structure with a hole, possibly circular or other geometrically shaped, used to receive and connect the second protrusion 1066. By inserting the second protrusion 1066, the support rod 1062 and the foot assembly 104 can be connected, allowing the user to quickly detach the top fan head structure 102, enabling the fan head structure 102 to be used independently.

[0098] The shape of the second protrusion 1066 is adapted to the hole design of the connecting part 1064 to ensure the firmness and stability of the connection.

[0099] In some embodiments, optionally, such as Figure 12 As shown, the support body 1042 rotates about a second axis relative to the connecting body 1044, and the second axis is located as follows: Figure 7 In the normal plane corresponding to the axis of the connecting part 1064 shown, that is, the second axis and the axis of the connecting part 1064 are perpendicular to each other, that is, there is a non-plane orthogonal positional relationship between the second axis and the axis of the connecting part 1064. The support body 1042 rotates around the second axis, so that the support body 1042 can swing or unfold freely along the direction of the second axis in the supported state.

[0100] like Figure 11 and Figure 12 As shown, the rotation of the support leg body around the second axis allows the legs to be extended and retracted. When the support leg assembly 104 is in the retracted state, as... Figure 11 As shown, the support body can rotate around the second axis, allowing multiple support bodies 1042 to be directly attached to the main body 1044, reducing space occupation; and when unfolded, as... Figure 12 As shown, the support body 1042 can rotate around the second axis to a predetermined angle, thereby forming a stable support structure.

[0101] Furthermore, between the stowed state and the unfolded support state, the support body 1042 rotates around the second axis by an angle of 60°-80°, and more specifically, by 70°.

[0102] In some embodiments, optionally, the support base 1042 and the connecting body 1044 are connected by a snap-fit ​​connection, and the support base 1042 and the connecting body 1044 are connected by a snap-fit ​​connection in the storage state. Specifically, the snap-fit ​​design generally uses buckles, fastening structures, etc., to ensure that the support base 1042 and the connecting body 1044 are firmly fixed. When the fan is not in use, the support base 1042 is tightly fixed to the connecting body 1044 by the snap-fit, which can prevent the support feet from loosening or falling off, and ensure the cleanliness and stability of the fan during storage. After the snap-fit ​​is released by the unlocking component 112, the support base 1042 can be quickly released and unfolded, which is convenient for users to quickly install or adjust.

[0103] By placing the unlocking element 112 on the connecting body 1044, the locking relationship between the foot support body 1042 and the connecting body 1044 is released. Specifically, the structure of the unlocking element 112 includes, but is not limited to, a button, pull ring, knob, or other mechanical triggering device, and the user releases the foot support by triggering the unlocking element 112.

[0104] It is understandable that the unlocking component 112 can trigger a mechanism to release the fixed connection between the support leg body and the connecting body 1044, allowing the support leg to be smoothly extended or retracted. Users can quickly release the latch and extend the support leg assembly 104 by simply touching or operating the unlocking component 112, improving the convenience and comfort of using the fan, especially when it is necessary to quickly adjust the fan's posture or height.

[0105] In some embodiments, optionally, when the support leg assembly 104 is in the extended support state, the ends of the multiple support legs away from the fan head structure 102 are on the same plane to ensure that the support legs can provide stable support.

[0106] Specifically, when the support leg assembly 104 is deployed, the ends of the support legs 1042 furthest from the fan head structure 102 will be on the same plane, meaning all support legs 1042 form a single plane on the support surface. This ensures that the force on the legs is even and stable, preventing any leg from bearing excessive pressure and ensuring the stability of the fan. Regardless of how the fan's weight is distributed, all legs can share the load.

[0107] During the unfolding process, the support body will be adjusted to be perpendicular to or at a certain angle to the fan head structure 102, so that multiple support bodies present the same height and horizontal line on the support surface.

[0108] The unfolding angle and rotation direction of the support body are limited by the design of the support assembly 104. When the support assembly 104 unfolds, the support body will automatically adjust to ensure that its far ends are aligned with the same plane.

[0109] When all the legs are on the same plane, the support system acts like a stable triangular support structure, enhancing the overall support effect. This design ensures that the fan remains stationary regardless of external forces encountered during deployment, guaranteeing stable operation of the equipment.

[0110] Whether the ground where the fan is placed is flat or slightly inclined, the planar design of the support body can effectively distribute the load, allowing the fan to maintain high stability in various environments.

[0111] Based on any of the above embodiments, optionally, when the support leg assembly is in the retracted state, a portion of the outer surface of the support leg body will be flush with the outer surface of the support rod. Furthermore, the flush outer surface is the surface of the part where the support leg body is connected to the support rod, thereby making the support leg assembly and the support rod form an integrated appearance structure, reducing the appearance of protrusions and grooves, improving aesthetics on the one hand, and improving the safety of equipment use on the other hand.

[0112] Specifically, for the design where the connecting part is hole-shaped and the end of the connecting body facing the base structure has a second protrusion, the circumferential outer surface of part of the support body is flush with the circumferential outer surface of part of the support rod where the connecting part is located.

[0113] For a solution where multiple support legs are stacked when the support leg assembly is in the stowed state, the connecting part is groove-shaped, and the upper surface of the top support leg is flush with the opening of the connecting part.

[0114] Based on any of the above embodiments, optionally, such as Figure 3 As shown, a universal joint 1046 is provided on the connecting body 1044 and is movably connected to the fan head structure 102, so that the position of the fan head structure 102 can be flexibly adjusted through the universal joint 1046, that is, the fan head structure 102 is allowed to swing freely at multiple angles while maintaining a stable connection.

[0115] In one specific embodiment, a triangular support structure is provided that allows for one-button pop-out of the support rod 1062 and can be opened. This simple, modular design allows the fan product to be switched between different heights, providing users with multiple usage scenarios for both tabletop and stand applications. After the triangular support frame (i.e., the support leg assembly 104) is detached with one button (i.e., the unlocking component 112), the three supports (i.e., the support leg body 1042) can be opened by hand and placed. Each triangular support can be opened by 70°, and the locking structure securely positions the triangular support.

[0116] In another specific embodiment, a rotatable and retractable support structure is provided. The legs are rotated out for support during use, and the support can be rotated and retracted for storage when not in use. The fan consists of a detachable fan head (i.e., fan head structure 102), a column (i.e., support rod 1062), and a chassis (i.e., base structure 106). It can be used as a whole or the fan head can be disassembled for independent use. The top of the column has a cavity (i.e., connecting part 1064) for assembling the legs, and the fan head can be fixed by weight and a limiting structure.

[0117] The fan head support (i.e., support assembly 104) has a certain tilt angle and consists of three supports (i.e., support body 1042). It can rotate and open, and is fixed to each other by fasteners, limiting the relative rotation angle to ensure that the force is evenly distributed when open, supporting the fan head for independent use. When the fan head is used independently, the supports are movably connected to the fan head, enabling the fan head to oscillate left and right and adjust its angle up and down.
