Description

Technical Field

[0001] This utility model relates to the field of electrical technology, and in particular to a magnetic fan that is easy to store. Background Technology

[0002] Currently, portable fans have become a common cooling device for daily travel, and users have placed higher demands on their stability and adaptability to various scenarios. Most portable fans on the market typically have support feet at the bottom of the base. For example, the support feet of the CN202673741U fan can usually be rotated to switch between an extended and retracted state, thus balancing stable support during use with reduced size when not in use. This support foot assembly is generally composed of plastic parts connected by a shaft, and its rotating and retracting function has become a typical means in this field to address the needs of portability and standing.

[0003] However, the functional design of these conventional rotating support leg structures is always optimized around the single scenario of providing support on a flat surface. After the support leg is extended, the force between it and the surface relies solely on the structure's own gravity and static friction. This single mode of mechanical action significantly reduces the product's stability when facing various common materials such as smooth metal surfaces, posing a risk of slippage or tipping. Therefore, existing rotating support leg structures, due to their limitation to providing only single-plane support, suffer from insufficient adaptability to various application scenarios. Utility Model Content

[0004] The main purpose of this invention is to propose a magnetic fan that is easy to store, aiming to solve the technical problem that the existing technology is limited to providing a single flat support and has insufficient adaptability to various usage scenarios.

[0005] To achieve the above objectives, this utility model proposes a magnetic fan that is easy to store, including a blowing structure and a base. The blowing structure is installed on the base and supported by the base. The bottom of the base is provided with a support foot, and the bottom of the base is provided with a storage part for accommodating the support foot. The support foot can rotate relative to the storage part and has a first position for being accommodated in the storage part and a second position for being extended out from the storage part. The support foot includes a body and a magnetic part fixed to the body. The magnetic part is at least partially exposed from the body and is configured to adhere to an iron surface.

[0006] Furthermore, a rotating shaft structure is provided between the support foot and the storage part. The rotating shaft structure is located in the middle of the support foot and the storage part and is configured as the rotation center of the support foot relative to the storage part. The magnetic part is located on the side of the rotating shaft structure.

[0007] Furthermore, the rotating shaft structure is a column integrally formed from the bottom of the base, and the main body is provided with a through-hole that is configured for the column to pass through.

[0008] Furthermore, the main body defines a first receiving cavity below the opening, and a damping structure is provided in the first receiving cavity. The damping structure abuts against the column and is configured to provide damping force when the support leg rotates relative to the storage part, thereby making the support leg stably maintained in the first position and the second position.

[0009] Furthermore, the main body is provided with a second receiving cavity for accommodating the magnetic suction part. The second receiving cavity is defined as a cavity that is open at the bottom, so that the bottom surface of the magnetic suction part is in complete contact with the outside.

[0010] Furthermore, there are two magnetic suction parts, which are mirror images of each other at both ends of the main body.

[0011] Furthermore, foot pads are provided between the magnetic parts, and the foot pads are fixedly connected to the bottom of the main body.

[0012] Furthermore, an intermediate component is provided between the support leg and the storage part, and the intermediate component is fixedly connected to the magnetic part.

[0013] Furthermore, the intermediate component includes a rod and a fixing part, the fixing part being located at the end of the rod facing the magnetic part and used to prevent the magnetic part from falling.

[0014] Furthermore, the magnetic part is provided with a connecting hole that gradually expands from top to bottom, through which the rod can pass, while the fixing part cannot pass through the connecting hole.

[0015] This utility model includes a blower structure and a base. The blower structure is mounted on the base, and the base has a support foot at its bottom. A corresponding storage portion for accommodating the support foot is also provided at the bottom of the base. The support foot is rotatable relative to the storage portion and has a first position where it is housed within the storage portion and a second position where it extends out from the storage portion. The support foot includes a body and a magnetic suction portion fixed to the body, with at least a portion of the magnetic suction portion protruding from the body. This utility model overcomes the technical deficiency of existing technologies that rely solely on friction on smooth metal surfaces by utilizing the adsorption force generated between the magnetic suction portion and the ferrous surface. This improves the fan's anti-slip and anti-tipping capabilities when placed, effectively expanding its stable usage scenarios. In summary, this utility model, by forming a force perpendicular to the usage surface through the magnetic suction portion, has beneficial technical effects applicable to a wider range of scenarios.

[0026] This invention proposes a magnetic fan that is easy to store.

[0027] In this embodiment of the utility model, such as Figures 1 to 5As shown, this easy-to-store magnetic fan includes a blowing structure 1 and a base 2. The blowing structure 1 is mounted on the base 2 and supported by the base 2. The base 2 has a support foot 3 at its bottom, and a corresponding storage portion 21 for accommodating the support foot 3 is provided at the bottom of the base 2. The support foot 3 can rotate relative to the storage portion 21 and has a first position where it is accommodated in the storage portion 21 and a second position where it extends out from the storage portion 21. The support foot 3 includes a body 31 and a magnetic suction portion 32 fixedly disposed on the body 31. The magnetic suction portion 32 is at least partially exposed from the body 31 and configured to adhere to an iron surface. Specifically, the core improvement of this utility model lies in integrating the rotatable and retractable support foot 3 structure with the magnetic suction function. Compared to the limitations of existing technologies where the support foot 3 has a single function and can only provide support on a flat surface, this utility model provides a magnetic suction part 32 on the support foot 3 body 31. This allows the support foot 3 to provide support not only through physical contact when it is extended from the first position to the second position, but also through the magnetic attraction force generated between the magnetic suction part 32 and the iron surface, which significantly enhances the adhesion stability of the fan on a smooth metal surface.

[0028] This structural design produces several beneficial effects: First, the fact that the magnetic suction part 32 is at least partially exposed from the main body 31 ensures that the magnetic lines of force can effectively penetrate and form a complete magnetic circuit closure with the iron surface, thereby providing sufficient adsorption force; Second, the rotatable nature of the support foot 3 allows it to be completely housed in the storage part 21 when stored, avoiding scratches or foreign objects that may be caused by the exposed magnetic suction part 32, ensuring the integrity and portability of the stored state; Third, compared with the pain point of traditional fans being prone to slipping and tipping on high-speed rail carriages, metal desks, and kitchen appliance surfaces, this greatly expands the applicable scenarios of the product.

[0029] Understandably, the fixing method of the magnetic suction part 32 is not limited to a single form such as embedding or bonding. In some alternative embodiments of this utility model, the magnetic suction part 32 can also be fixed by snapping, interference fit with the body 31, or by adopting a detachable design, as long as it can be ensured that the magnetic suction part 32 remains relatively fixed to the body 31 in the working state, and at least part of its surface can be used for adsorption. In addition, the material of the magnetic suction part 32 is not limited to permanent magnets, but can also be a magnetic element that requires external power supply, such as an electromagnet, and the on and off of its magnetic force can be controlled by the internal circuit of the base 2.

[0030] It should be noted that the aforementioned first and second positions refer to the two extreme working positions of the support leg 3 relative to the bottom of the base 2. The first position, the stowed position, refers to the state where the support leg 3 is rotated until its extension direction is basically parallel to the bottom contour of the base 2, and it is entirely housed within the stowed portion 21. At this position, the overall profile of the fan is most compact, facilitating carrying and storage. The second position, the extended working position, refers to the state where the support leg 3 rotates out from the stowed portion 21, and its extension direction is approximately perpendicular to the bottom of the base 2. At this position, the support leg 3 and the base 2 together form a stable support base, providing reliable standing support for the fan. Simultaneously, the magnetic suction part 32 is fully exposed and faces the placement surface, achieving the optimal working posture.

[0031] In some embodiments of this invention, a rotating shaft structure 22 is provided between the support leg 3 and the storage part 21. The rotating shaft structure 22 is located in the middle of the support leg 3 and the storage part 21, and is configured as the rotation center of the support leg 3 relative to the storage part 21. The magnetic suction part 32 is located on the side of the rotating shaft structure 22. Compared with the prior art where the rotating shaft is located at the end of the support leg 3 or a non-axial flip joint is used, setting the rotating shaft structure 22 in the middle of the support leg 3 and the storage part 21 allows the two ends of the support leg 3 (i.e., the end where the magnetic suction part 32 is installed) to move symmetrically around the center when the support leg 3 is unfolded and stored. This arrangement makes the change in the center of mass of the support leg 3 smaller during rotation, the movement more stable, and less prone to unexpected swaying.

[0032] Specifically, the rotating shaft structure 22 is preferably a column integrally formed from the bottom of the base 2, and the body 31 is provided with a through-hole 311 to allow the column to pass through. Compared with the existing technology that often uses independent pins, bolts and other rotating connecting parts that require additional assembly, this utility model achieves a reduction in the number of parts and a simplification of the structure by extending the column directly from the bottom of the base 2 as the rotating shaft. This design brings multiple benefits: firstly, it eliminates the procurement, management and assembly of independent shaft parts, reducing material and assembly costs; secondly, the integrally formed structure avoids the risk of failure caused by loosening or falling off of independent shaft parts, improving the long-term reliability of the rotating joint and the overall structural strength.

[0033] Furthermore, the design of the through-hole 311 facilitates the installation of the support leg 3, which can be easily installed onto the column by sliding it in laterally or from top to bottom. To ensure smooth rotation and avoid excessive wobbling, a small clearance fit is preferably provided between the through-hole 311 and the column. In addition, the through-hole 311 also makes routine maintenance of the support leg 3 (such as cleaning and lubrication) possible.

[0034] It is understood that the specific form of the rotating shaft structure 22 is not limited to the integrally formed column. In some alternative embodiments of this utility model, the rotating shaft structure 22 can also be implemented as a split structure, for example, a combination of a bushing that can be fixed to the bottom of the base 2 and an independent short shaft, or a shaft provided on the support foot 3 that fits with the shaft hole at the bottom of the base 2. As long as it can realize the function of the support foot 3 rotating relative to the storage part 21 about a fixed axis, it is acceptable.

[0035] Furthermore, the core of the rotating shaft structure 22 lies in achieving reliable relative angular displacement between the support leg 3 and the base 2, allowing switching between the unfolded and retracted positions. Its core purpose is to change the angle between the support leg 3 and the base 2. Therefore, the statement "the support leg 3 can rotate relative to the retracted portion 21" should be interpreted broadly, and the means of achieving this function should not be limited to the mechanical rotating shaft structure 22. In some alternative embodiments of this invention, a non-circular hinge with positioning function can be considered, or a combination of magnetic attraction and mechanical stops can be used (e.g., setting mutually attracting magnets on the support leg 3 and the retracted portion 21, and setting a limiting structure at a specific angle) to achieve angle changes and locking. As long as the mechanism ultimately achieves the angular displacement function of the support leg 3 from the retracted position parallel to the base 2 to the unfolded position perpendicular to the base 2, it should be interpreted as an embodiment where the support leg 3 can rotate relative to the retracted portion 21.

[0036] More specifically, the main body 31 defines a first receiving cavity 312 below the opening 311, and a damping structure 33 is provided within the first receiving cavity 312. The damping structure 33 abuts against the column and is configured to provide damping force when the support leg 3 rotates relative to the storage part 21, thereby stably maintaining the support leg 3 in the first position and the second position. Integrating the damping structure 33 into the specific space defined by the first receiving cavity 312 of the support leg 3 main body 31, and combining it with the integrally formed column, produces the following beneficial effects: First, it achieves a very high degree of structural integration. The damping structure 33 is completely accommodated and hidden in the first receiving cavity 312 inside the support leg 3, eliminating the need to create additional installation space on the seat 2 or the storage part 21. This makes the entire rotary joint structure very compact and simple in appearance, while effectively protecting the damping structure 33 from dust accumulation or physical damage due to exposure. Second, it provides a stable and uniform damping effect. The damping structure 33 directly and continuously abuts against the column, which serves as the center of rotation, ensuring that the support leg 3 experiences uniform and smooth resistance throughout the entire rotation stroke, thereby improving the operational feel. Thirdly, this built-in layout works in conjunction with the magnetic suction part 32 to jointly ensure the ultimate stability of the support leg 3 in the unfolded state (resistance to sliding and accidental folding) and its retention in the folded state.

[0037] Understandably, in some alternative embodiments of this invention, the damping structure 33 may be implemented as an O-ring fitted onto the column, a bushing made of engineering plastic with a high coefficient of friction, or a mating structure lubricated with viscous damping grease. Any implementation that utilizes the friction or adhesion between the element disposed within the first accommodating cavity 312 and the column to provide resistance should be considered an equivalent substitution of this invention.

[0038] In some embodiments of this invention, the main body 31 is provided with a second receiving cavity 313 for accommodating the magnetic suction part 32. The second receiving cavity 313 is defined as an open cavity at the bottom, so that the bottom surface of the magnetic suction part 32 is in complete contact with the outside. The second receiving cavity 313 is an optimized structure that works in conjunction with the magnetic suction part 32. By designing the second receiving cavity 313 as an open cavity at the bottom, this invention allows the adsorption bottom surface of the magnetic suction part 32 to be directly and completely exposed to the external environment. The second receiving cavity 313 reduces the non-magnetic medium in the magnetic field transmission path, allowing the magnetic energy of the magnetic suction part 32 to act on the target ferrous surface with almost no loss, thereby maximizing the adsorption force. This allows the fan to achieve a reliable fixing effect on vertical metal surfaces (such as refrigerator doors and metal filing cabinets) even in bumpy or vibrating environments. At the same time, the open structure at the bottom also facilitates cleaning and can effectively remove foreign matter such as iron filings that may adhere to the magnetic suction part 32 after long-term use.

[0039] Specifically, two magnetic suction parts 32 are provided, mirror-imagely positioned at both ends of the main body 31. More specifically, a foot pad 34 is provided between the magnetic suction parts 32, and the foot pad 34 is fixedly connected to the bottom of the main body 31. Positioning the two magnetic suction parts 32 mirror-imagely at both ends of the main body 31 is a preferred layout for achieving stable adsorption. Compared to a single magnetic suction part 32, this dual magnetic suction part 32 configuration establishes two symmetrical adsorption points with a certain distance between the support foot 3 and the iron surface. This design produces the following beneficial effects: First, it can effectively resist the overturning moment generated when the fan's center of gravity shifts or is subjected to lateral disturbances, improving the fan's anti-tipping ability and overall stability when placed on the iron surface; second, the symmetrical layout ensures a uniform distribution of adsorption force, avoiding localized stress concentration in the support foot 3, main body 31, or base 2 structure that may result from single-point adsorption.

[0040] The foot pads 34, located between the magnetic attachment parts 32 and fixed to the bottom of the main body 31, are a multifunctional design. Firstly, the foot pads 34 act as independent support points, forming a stable three-point support system together with the two magnetic attachment parts 32. When the fan is placed on a non-ferrous surface (such as a wooden or plastic tabletop), the foot pads 34 contact the surface and provide static friction for stable support. At this time, the magnetic attachment parts 32 are not active but are elevated by the foot pads 34, preventing direct contact and wear with the surface. When the fan is attached to a ferrous surface, the foot pads 34 act as a limiting and buffering structure: their slight but present compression deformation ensures that even with minor unevenness on the ferrous surface, the two magnetic attachment parts 32 can simultaneously and tightly adhere to the surface under the elastic adjustment of the foot pads 34, maximizing the contact area. Secondly, the elasticity of the foot pads 34 absorbs some vibration energy, improving quietness during use. Furthermore, the presence of the foot pads 34 protects the bottom of the main body 31 between the magnetic attachment parts 32 from scratches, enhancing the product's durability and perceived quality.

[0041] Similarly, the specific implementation of the foot pad 34 is not limited to a single form. Its material can be selected from polymers with good elasticity and coefficient of friction, such as rubber, silicone, and TPU. In addition to adhesive bonding, it can also be fixed to the bottom of the body 31 by snap-fitting, screw fixing, or integral molding with the body 31 (such as two-color injection molding).

[0042] In some embodiments of this invention, an intermediate component 4 is provided between the support foot 3 and the storage portion 21, and the intermediate component 4 is fixedly connected to the magnetic suction portion 32. It is worth noting that the magnetic suction portion 32 and the intermediate component 4 can be pre-assembled and tested as an independent sub-unit before being assembled with the support foot 3 body 31. This helps improve production efficiency and product quality consistency. Furthermore, the material of the intermediate component 4 can be different from that of the support foot 3 body 31 (usually plastic), a material more suitable for bonding with the magnetic suction portion 32, or a material with higher strength (such as metal), thereby optimizing the fixing strength and reliability of the magnetic suction portion 32. Finally, the intermediate component 4 can be designed with a specific structure to better adapt to the internal space of the storage portion 21, or to provide additional protection for the magnetic suction portion 32 during rotation, preventing direct collision or friction between it and the inner wall of the storage portion 21.

[0043] Specifically, a preferred structure for the intermediate component 4 is proposed here. The intermediate component 4 includes a rod portion 41 and a fixing portion 42. The fixing portion 42 is located at the end of the rod portion 41 facing the magnetic suction portion 32 and is used to prevent the magnetic suction portion 32 from falling. More specifically, the magnetic suction portion 32 has a connecting hole 321 that gradually expands from top to bottom. The rod portion 41 can pass through the connecting hole 321, while the fixing portion 42 cannot pass through the connecting hole 321. During assembly, the rod portion 41 passes through the gradually expanding connecting hole 321 of the magnetic suction portion 32. Since the lateral dimension of the fixing portion 42 is larger than the diameter of the narrowest part of the connecting hole 321, when the magnetic suction portion 32 tends to fall due to gravity or external force, the inner wall of its connecting hole 321 (especially the conical surface or stepped surface of the gradually expanding structure) will eventually be abutted by the fixing portion 42, thereby supporting the magnetic suction portion 32 and effectively preventing it from falling off from the working position. This purely mechanical fixing method offers higher long-term reliability compared to fixing relying solely on adhesives, and is less prone to failure due to adhesive aging or temperature changes. Simultaneously, the gradually expanding connecting hole 321 provides initial guidance and self-centering for the rod 41 during assembly, facilitating rapid alignment and installation. The specific shape of the fixing part 42 is not limited to a regular geometric shape; it can be implemented as a sphere, an ellipsoid, a horizontal pin perpendicular to the rod 41, or a disc-shaped structure with a diameter larger than the rod 41, etc. Similarly, the gradually expanding connecting hole 321 from top to bottom is a functional description of the hole wall structure; it can be a continuous conical surface or a stepped hole with a stepped change. As long as its structure satisfies the core constraint that "the rod 41 can pass through while the fixing part 42 cannot," thereby achieving the function of preventing the magnetic part 32 from falling, it should be considered an equivalent alternative.

[0044] In some embodiments of this utility model, the side of the base 2 is provided with a rotatable pull ring 5. When the support foot 3 is placed on an inclined surface, in addition to the stable placement achieved by the body 31 and the magnetic part 32, the pull ring 5 can also be fastened to some reference objects (such as rod-shaped or cylindrical objects), thereby further enhancing the stability during use and increasing the applicable scenarios. The structure for achieving the auxiliary fixation is not limited to the rotatable pull ring 5. In some alternative embodiments of this utility model, the pull ring 5 can be implemented as an ear seat with a through hole, a U-shaped buckle, or a retractable hook, rope, or other structures to achieve the same function.

[0045] The following content serves as an explanation of the working principle of this utility model:

[0046] The working principle of this invention is based on the synergistic effect of the rotatable storage characteristic of the support foot 3 and the adsorption function of the magnetic part 32. When needed, the user rotates the support foot 3 from the first position of the storage part 21 to the second position. During this process, the support foot 3 rotates around the rotation axis structure 22, while the built-in damping structure 33 provides appropriate resistance, allowing the support foot 3 to remain stably at any unfolded angle and ultimately be firmly held in the fully unfolded second position.

[0047] When the fan is placed on a ferrous surface, the fully exposed magnetic suction part 32 at the bottom of the support foot 3 comes into direct contact with the ferrous surface, generating a strong magnetic attraction force. This attraction force, combined with the mechanical support of the support foot 3, overcomes the fan's weight and possible external interference, ensuring that the fan maintains extremely high stability on smooth or tilted ferrous surfaces, effectively solving the problem of traditional fans easily slipping and tipping over on such surfaces.

[0048] When storing, the user rotates the support foot 3 in the opposite direction to return it to the first position of the storage section 21. The rotation and linear storage action of the support foot 3 allows it to be compactly housed at the bottom of the base 2, and the magnetic part 32 is also completely protected inside, avoiding unnecessary scratches or foreign objects from being attracted, ultimately minimizing the overall size and greatly improving the portability of the product.

[0049] Furthermore, the optional intermediate component 4 optimizes the fixing reliability of the magnetic suction part 32; the side pull ring 5 allows users to perform auxiliary binding and fixing in special scenarios, further expanding the product's applicability and stability. Through the coordinated work of the above-mentioned components, this utility model ultimately achieves a high degree of unity between stable standing, wide adsorption, and compact storage.

[0050] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
