Description

Technical Field

[0001] This utility model relates to the field of folding fans, and in particular to a novel folding fan. Background Technology

[0002] In recent years, folding electric fans have rapidly risen in the market and are very popular with consumers. These products feature a wide-angle, flexible fan head and column, and the column tube is extendable and adjustable. When not in use, the folding and retracting design allows the fan head, column, and other components to be stored on the base, reducing the product's footprint and improving storage convenience and portability. However, currently mainstream folding fans, when folded, can only have the fan head stacked on the base and cannot be further compressed for storage. Even when folded, they still occupy a considerable amount of space, making efficient storage difficult for consumers with limited living space. Utility Model Content

[0003] In order to overcome at least one of the defects of the prior art, the present invention provides a novel fan, which, through the storage cavity structure design on the base, allows the fan head, column and other components to be stored inside the base, thereby greatly reducing the overall volume of the product after storage and achieving more efficient space utilization.

[0004] The technical solution adopted by this utility model to solve its problem is:

[0005] A new type of folding fan includes:

[0006] A fan head assembly, comprising a fan head housing and a fan blade mechanism, wherein the fan blade mechanism is installed within the fan head housing;

[0007] The base has a storage cavity.

[0008] The column assembly includes a support rod, a first rotating member, and a second rotating member. The support rod includes at least a first segment and a second segment, which can move closer to or further away from each other to allow the support rod to be in a folded or unfolded state. The first segment is rotatably connected to the fan head housing via the first rotating member. The second segment is rotatably connected to the base via the second rotating member. The second segment is used to rotate when the support rod is in the folded state and fold into the storage cavity.

[0009] Furthermore, the fan head housing is provided with an insertion part, which is used to insert into the storage cavity when the support rod is in a folded state.

[0010] Furthermore, the insertion part is provided with a clearance groove in the middle, which is used to accommodate the support rod in a folded state when the insertion part is inserted into the storage cavity.

[0011] Furthermore, it also includes a limiting component, a mounting cavity on the base, the mounting cavity having a mounting notch; the second rotating member includes a rotating shaft and a connecting shaft, one end of the connecting shaft is connected to the second rod segment, and the other end of the connecting shaft is connected to the rotating shaft; the rotating shaft is rotatably connected to the mounting cavity via the mounting notch and abuts against the end wall of the mounting notch;

[0012] The limiting component includes a limiting member, which is movably connected to the mounting cavity and can move closer to or further away from the rotating shaft. When the limiting member moves closer to the rotating shaft, it abuts against the rotating shaft to limit the rotational movement of the rotating shaft.

[0013] Furthermore, the limiting component also includes an elastic member that abuts against the limiting member and provides an elastic stress to drive the limiting member to move closer to the rotation axis.

[0014] Furthermore, the limiting component also includes a fixed base, the fixed base is provided with a sliding groove, and the limiting component is provided with a slider, the slider slidingly engaging with the sliding groove.

[0015] Furthermore, the limiting member is also provided with a through cavity and a limiting protrusion. The limiting protrusion is located at one end of the limiting member away from the through cavity. The rotating shaft is provided with a guide block. The guide block abuts against the limiting protrusion and is used to press the limiting protrusion when subjected to force, so as to guide the limiting member to move away from the rotating shaft.

[0016] The cavity has a through-post, and the elastic component is sleeved on the through-post.

[0017] Furthermore, the guide block is provided with a guide slope, which abuts against the limiting protrusion and is used to guide the limiting member away from the rotation axis when the guide block is subjected to force.

[0018] Furthermore, the base is provided with a limiting notch, which is connected to the mounting cavity; the limiting member is provided with a limiting buckle, which passes through the limiting notch and is used to guide the limiting member to move closer to or away from the rotating shaft when subjected to force.

[0019] Furthermore, the support rod package also includes at least one connecting rod segment, wherein the first rod segment is slidably connected to the connecting rod segment, and the second rod segment is slidably connected to the connecting rod segment.

[0020] In summary, the novel folding fan provided by this utility model has the following technical effects: When the product needs to be folded, the first and second segments of the support rod can be brought close to each other until the support rod is in a folded state. At this time, the support rod can be rotated toward the storage cavity on the base to fold it into the storage cavity. At the same time, the fan head assembly is simultaneously folded into the storage cavity under the drive of the support rod, so that the fan head assembly and the column assembly are folded into the base. After being folded, the overall volume is greatly reduced, achieving more efficient space utilization. Attached Figure Description

[0038] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0039] See Figures 1 to 9 This utility model discloses a novel folding fan, including a fan head assembly 10, a column assembly 30, and a base 20, with a storage cavity 21 provided on the base 20. Specifically, the fan head assembly 10 includes a fan head housing 11 and a fan blade mechanism 12, with the fan blade mechanism 12 installed inside the fan head housing 11. The column assembly 30 includes a support rod 31, a first rotating member 32, and a second rotating member 33. The support rod 31 includes at least a first rod segment 311 and a second rod segment 312, which can move closer to or further away from each other to allow the support rod 31 to be in a folded or unfolded state. The first rod segment 311 is rotatably connected to the fan head housing 11 via the first rotating member 32, and the second rod segment 312 is rotatably connected to the base 20 via the second rotating member 33. The second rod segment 312 can rotate when the support rod 31 is in the folded state and fold into the storage cavity 21.

[0040] Based on the above structure, when the fan needs to be folded, firstly, operate the support rod 31 of the column assembly 30 to bring the first rod segment 311 and the second rod segment 312 closer together. Through their relative movement, the support rod 31 changes from an unfolded state to a folded state, significantly shortening its length. Subsequently, the second rod segment 312 rotates about the second rotating member 33 as an axis toward the storage cavity 21 on the base 20, storing the folded support rod 31 into the storage cavity 21. Since the first rod segment 311 is rotatably connected to the fan head housing 11 through the first rotating member 32, during the rotation and storage of the second rod segment 312, it will drive the fan head assembly 10 to move synchronously toward the storage cavity 21. When it approaches the storage cavity 21, the fan head housing 11 can be rotated to correspond to the storage cavity 21, until the fan head assembly 10 can also be stored in the storage cavity 21 of the base 20. In this way, after folding, the fan head assembly 10 and the column assembly 30 can be stored in the base 20, which greatly reduces the space volume of the product, achieves efficient storage, and is convenient for storage and carrying.

[0041] When unfolding the fan, the second rod segment 312, which is stored in the storage cavity 21 of the base 20, is first rotated out of the storage cavity 21 and unfolded outward around the second rotating member 33. As the second rod segment 312 rotates, the first rod segment 311, which is connected to the second rod segment 312 through the first rotating member 32, and the fan head assembly 10 are also unfolded. Next, the first rod segment 311 and the second rod segment 312 are moved away from each other, so that the support rod 31 gradually changes from a folded state to an unfolded state, restoring it to its normal length. At this time, the fan head assembly 10 is at a suitable height and angle, and the position of the fan blade mechanism 12 within the fan head housing 11 is also adjusted. The entire fan is now fully unfolded and in normal working condition, providing users with a comfortable airflow experience.

[0042] Specifically, in this embodiment, the first segment 311 and the second segment 312 adopt a nested design. A limiting protrusion 411 is provided on the inner wall of the second segment 312, and a corresponding limiting groove 431 is provided on the outer wall of the first segment 311. They can move closer or further apart by sliding. A locking button can be installed at the end of the segment. When unfolded, the button is locked into the groove. When folded, pressing the button releases the lock, ensuring stability and ease of folding.

[0043] Of course, the first segment 311 and the second segment 312 of the support rod 31 can also be connected by a hinge shaft. By setting a torsion spring at the connection point, the torsion spring provides support to keep the rod upright when unfolded, and overcomes the resistance of the torsion spring to bend the segment when folded. A buckle can also be set at the hinge point, which automatically locks when unfolded and unlocks manually when folded to prevent accidental folding.

[0044] The specific number of the first segment 311 can be set to one, two, or more depending on the required unfolding height of the fan head assembly 10.

[0045] It should be noted that the storage cavity 21 can be a groove formed on the base 20 and matched with the shape of the fan head housing 11 so that the fan head housing 11 can be inserted into it when moving towards it. Of course, the base 20 can also be set with a hollow structure, so that the storage cavity 21 is integrally formed on the base 20.

[0046] Furthermore, in this embodiment, the first rotating member 32 can be an existing steering ball joint. During installation, a matching groove is provided on the fan head housing 11, and the ball joint is embedded into the fan head housing 11 to achieve a rotatable connection. Alternatively, the first rotating member 32 can be an existing shaft, which is installed by providing a corresponding rotating groove on the fan head housing 11. Additionally, during installation, a rubber coating or damping oil layer can be applied to the outer periphery of the first rotating member 32 to allow the fan head housing 11 to hover at a designated position after rotation.

[0047] Similarly, the second rotating component 33 can also be an existing rotating shaft, and by providing a corresponding rotating groove on the base 20, the second rotating shaft 332 can be rotatably connected to the base 20. Likewise, the rubber coating or damping oil layer on the outer periphery of the first rotating component 32 allows the support rod 31 to be suspended at a designated position after rotation.

[0048] More specifically, the fan blade mechanism 12 in this embodiment can be selected from existing axial flow fans, centrifugal fans, etc.

[0049] Furthermore, the fan head housing 11 is provided with an insertion part 111, which is inserted into the storage cavity 21 when the support rod 31 is in a folded state.

[0050] Specifically, when folding the fan, the first segment 311 and the second segment 312 of the support rod 31 are brought close together to fold it. Then, with the second rotating component 33 as the axis, the folded support rod 31 is rotated toward the storage cavity 21 of the base 20. During the rotation, the angle of the fan head housing 11 is adjusted simultaneously so that the insertion part 111 on the fan head housing 11 is aligned with the entrance of the storage cavity 21. When the support rod 31 is completely folded into the storage cavity 21, the insertion part 111 on the fan head housing 11 is inserted into the storage cavity 21, so that it is tightly against the cavity wall. This forms a stable mechanical fit between the insertion part 111 and the storage cavity 21, effectively limiting the displacement of the fan head housing 11 and reducing the swaying amplitude in the folded state, making the overall folding of the fan more stable and reliable.

[0051] It should be noted that the insertion part 111 can be provided with a protruding structure on the fan head housing 11, such as a protruding ring or protruding block that matches the storage cavity 21 on the fan head housing 11, so that it can be inserted into the storage cavity 21.

[0052] Furthermore, a clearance groove is provided in the middle of the insertion part 111, which accommodates the support rod 31 in a folded state when the insertion part 111 is inserted into the storage cavity 21.

[0053] Specifically, when the support rod 31 is folded into the storage cavity 21, its end joint or connecting shaft 331 may physically interfere with the main body of the insertion part 111 (such as collision or squeezing), causing the fan head housing 11 to be unable to be inserted into the storage slot. Therefore, in this embodiment, an avoidance groove is provided on the insertion part 111. The outline of the avoidance groove matches the shape of the support rod 31 after it is folded (for example, an arc groove is adapted to a cylindrical support rod 31, and a U-shaped groove is adapted to a rectangular rod), providing it with a dedicated storage space so that the insertion part 111 and the support rod 31 are embedded in each other in the storage state, reducing the gap between the two and preventing shaking while compressing the overall volume.

[0054] Furthermore, it also includes a limiting component 40, a mounting cavity 22 on the base 20, the mounting cavity 22 having a mounting notch 23, the second rotating member 33 including a rotating shaft 332 and a connecting shaft 331, one end of the connecting shaft 331 being connected to the second rod segment 312, and the other end of the connecting shaft 331 being connected to the rotating shaft 332; the rotating shaft 332 is rotatably mounted in the rotating groove and rotatably connected to the mounting groove via the mounting notch 23, and abuts against the end wall of the mounting notch 23; the limiting component 40 includes a limiting member 41, the limiting member 41 being movably connected to the mounting cavity 22, and used to move closer to or away from the rotating shaft 332 when subjected to force, and when moving closer to the rotating shaft 332, abutting against the rotating shaft 332 to limit the rotational movement of the rotating shaft 332.

[0055] Specifically, when the rotating shaft 332 is inserted into the mounting groove through the mounting notch 23, it is rotatably connected to the base 20. At the same time, the outer peripheral surface of the rotating shaft 332 and the end wall (such as the left and right side walls) of the mounting notch 23 form a mechanical hard limit to limit the maximum rotation angle of the rotating shaft 332.

[0056] Furthermore, when the rotating shaft 332 drives the support rod 31 to rotate and fold, an external force can be applied to the limiting member 41 to move it closer to the outer circumference of the rotating shaft 332 and abut it, preventing it from continuing to rotate and keeping the support rod 31 in a preset position, preventing it from wobbling. When it needs to be unfolded again, simply apply an external force to the limiting member 41 again to move it away from the rotating shaft 332, so that the support rod 31 can rotate and unfold again.

[0057] It should be noted that the limiting member 41 in this embodiment can be a block-shaped structure or a rod-shaped structure (such as a limiting block or a limiting post). During assembly, one end of the limiting member 41 is connected to the inner wall of the mounting cavity 22 through the elastic member 42, and the other end faces and abuts against the rotating shaft 332. Thus, when rotation occurs, an external force is applied to the limiting member 41, at which time the elastic member 42 is compressed, moving it away from the rotating shaft 332. When the rotating shaft 332 stops rotating, the elastic member 42 will restore its elastic deformation, driving the driving member to move closer to the limiting member 41 again, thus restricting the rotational movement of the rotating shaft 332.

[0058] Of course, the limiting component 41 can also be a pin structure. During assembly, it is connected to the mounting cavity 22 via a spring or manual lever, and has a matching limiting hole on the rotating shaft 332. After the support rod 31 is extended into place, the user can manually push the pin (or the spring automatically ejects the pin) to insert it into the positioning hole of the rotating shaft 332, forming a mechanical stop and restricting the rotation of the rotating shaft 332. The user can then manually pull the pin out of the positioning hole. When it is necessary to release the limit, the user can manually pull the pin out of the positioning hole to release the limit.

[0059] Preferably, the limiting component 40 in this embodiment also includes an elastic component 42 (such as a spring, sheet metal, etc.). During assembly, one end of the elastic component 42 is installed in the mounting cavity 22, and the other end abuts against the limiting member 41. In this way, the elastic component 42 generates elastic stress through its own deformation, which continuously drives the limiting member 41 to move towards the rotating shaft 332, so that the limiting member 41 and the rotating shaft 332 remain in contact or have a tendency to quickly abut. When the rotating shaft 332 is forced to squeeze the limiting member 41 by external force (such as the manual adjustment support rod 31), the elastic component 42 will compress and deform to store energy. At this time, the rotating shaft 332 can rotate. When the external force is removed, the elastic stress drives the limiting member 41 to quickly reset and continue to achieve the limiting. No additional drive mechanism (such as a motor or button) is required; the limiting is achieved solely by elastic stress, resulting in a simple structure.

[0060] More specifically, the limiting component 40 also includes a fixed base 43. During assembly, the fixed base 43 can be fixedly installed in the mounting cavity 22, and a sliding groove 431 is provided on the fixed base 43. A slider 414 is provided on the limiting member 41. The slider 414 is embedded into the sliding groove 431 and slides. At this time, the two ends of the elastic member 42 can abut against the fixed base 43 and the limiting member 41 respectively, so as to provide axial guidance for the elastic member 42 and the limiting member 41 through the sliding groove 431 of the fixed base 43, so that the elastic stress is directly transmitted along the sliding direction of the limiting member 41 (i.e., the radial direction of the rotation shaft 332), avoiding stress deviation that causes the elastic member 42 to bend or fail, so that the limiting member 41 can move according to the predetermined trajectory.

[0061] Furthermore, the limiting member 41 is also provided with a through cavity 412 and a limiting protrusion 411. The limiting protrusion 411 is located at the end of the limiting member 41 away from the through cavity 412. The rotating shaft 332 is provided with a guide block 3321. The guide block 3321 abuts against the limiting protrusion 411 and is used to press the limiting protrusion 411 when subjected to force, so as to guide the limiting member 41 to move away from the rotating shaft 332. The through cavity 412 has a through post 4121, and the elastic member 42 is sleeved on the through post 4121.

[0062] Based on this structure, by providing a through cavity 412 on the limiting member 41 and a through post 4121 therein, an installation reference is provided for the elastic member 42, so that its axis is consistent with the movement direction of the limiting member 41.

[0063] Furthermore, by setting a guide block 3321 (such as a block structure with a slope or arc surface) on the side of the rotating shaft 332 facing the limiting protrusion 411 and abutting against the limiting protrusion 411, specifically when the guide block 3321 is a block structure with a slope, when the rotating shaft 332 needs to rotate, the slope on the guide block 3321 will decompose the rotational force of the rotating shaft 332 into a force perpendicular to the slope, that is, a radial force on the rotating shaft. This radial component overcomes the resistance of the elastic component 42, forcing the limiting component 41 to slide away from the rotating shaft 332 along the slide groove 431 of the fixed seat 43 via the slider 414 until the limiting protrusion 411 completely disengages from the limiting structure of the rotating shaft 332, thereby unlocking.

[0064] When the guide block 3321 is a block structure with an arc surface, and the arc surface is convex (the radius of curvature increases from the axis outward), as the rotating shaft 332 rotates, the radius of curvature of the contact point gradually increases, and the radial component always points outward, forcing the limiting protrusion 411 to drive the limiting member 41 away from the rotating shaft 332 along the slide groove 431, compressing the elastic member 42 (such as a spring), making the unlocking process easier.

[0065] Preferably, in this embodiment, the guide block 3321 is provided with a guide slope 33211, which abuts against the limiting protrusion 411 so that the rotational force of the rotating shaft is decomposed into a force perpendicular to the slope, that is, a force in the radial direction of the rotating shaft 332 through the guide slope 33211, thereby forcing the limiting member 41 to move away from the rotating shaft 332.

[0066] Furthermore, the base 20 is also provided with a limiting notch 24, which is connected to the mounting cavity 22; the limiting member 41 is provided with a limiting buckle 413, which passes through the limiting notch 24 and is used to guide the limiting member 41 to move closer to or away from the rotating shaft 332 when subjected to force.

[0067] Specifically, the limiting buckle 413 is inserted into the notch, allowing it to slide only along the length of the notch or a preset trajectory. This enables the limiting member 41 to move closer to or further away from the rotating shaft 332 along the preset trajectory, preventing the limiting member 41 from wobbling or shifting. Furthermore, the limiting buckle 413, embedded in the notch, forms a physical barrier, preventing the limiting member 41 from detaching from the base 20 even when subjected to lateral forces (such as vibration or impact). This avoids mechanism failure due to component detachment, improving the stability and reliability of the limiting action.

[0068] More specifically, users can also apply external force to the limiting member 41 by moving the limiting buckle 413 outside the base 20. In this way, when the elastic component 42 loses elasticity due to long-term use or becomes stuck, users can assist the limiting member 41 to slide by moving it externally without disassembling the base 20, so as to quickly unlock or reset and improve the flexibility of operation.

[0069] Furthermore, the support rod 31 also includes at least one connecting rod segment 313, with a first rod segment 311 slidably connected to the connecting rod segment 313 and a second rod segment 312 slidably connected to the connecting rod segment 313.

[0070] Specifically, during assembly, the connecting rod segment 313 serves as an intermediate transition structure, simultaneously sliding and engaging with the first rod segment 311 and the second rod segment 312 to form at least a three-section telescopic structure. This allows users to adjust the total length of the support rod 31 as needed by sliding each segment to meet the height requirements of different scenarios (such as switching between desktop and floor fans). When folding is required, the first rod segment 311 and the second rod segment 312 slide towards the connecting rod segment 313, ultimately forming a multi-layered nested structure that allows it to be folded into the storage cavity 21.

[0071] It should be noted that during assembly, linear guide rails can be provided on both sides of the connecting rod segment 313, and corresponding sliding grooves 431 can be provided on the inner walls of the first rod segment 311 and the second rod segment 312. Sliding is achieved by the cooperation of the guide rails and the sliding grooves 431. Alternatively, the first rod segment 311 and the second rod segment 312 can be designed as hollow tubes, and the connecting rod segment 313 can be a solid rod or a hollow tube with an outer diameter smaller than the inner diameter of the first and second rod segments 312. The two ends of the connecting rod segment 313 can be inserted into the first rod segment 311 and the second rod segment 312 respectively to form a "sleeve-type" sliding fit.

[0072] In addition, the number of connecting rod segments 313 can be set to one, two, or more, depending on the actual number of fan segments that need to be deployed.
