Description

Technical Field

[0001] This invention relates to the field of smart wearable device technology, specifically to a cross-category universal magnetic fragrance interface system, which enables the same fragrance module to be interchangeably worn in various headwear categories such as headbands, hair clips, and hair ties. Background Technology

[0002] With the upgrading of consumption and the pursuit of a higher quality of life, fragrance has gradually become an important added value of personal care products. In the field of hair accessories, combining fragrance with hair accessories can achieve continuous fragrance while wearing the accessories, meeting users' personalized fragrance needs in scenarios such as sports, commuting, and social occasions.

[0003] In the existing technology, the magnetic modular fragrance headband mainly has the following technical problems: First, the product categories are limited. Existing patents for magnetic fragrance headbands mainly focus on headbands and hairbands, such as the magnetic modular fragrance headband disclosed in CN [Patent 1] and the controllable fragrance diffusion structure for sports headbands disclosed in CN [Patents 3 / 4]. These technical solutions deeply bind the magnetic interface to the structure of specific product categories, explicitly defining "headband body" or "hairband body" in the claims, making it impossible to naturally extend to other head accessory categories such as hair clips and hair ties. Hair clips have a clamping mechanical structure, and hair ties have a ring-shaped fabric structure. Their physical forms are fundamentally different from the arc-shaped embrace of headbands and the binding of hairbands, making it impossible to directly apply existing magnetic interfaces.

[0004] Secondly, the wearing stability is insufficient. Existing technologies lack a dedicated anti-slip design between the magnetic base and the headwear carrier. Under dynamic conditions such as sweating during exercise or head movement, the magnetic module is prone to slippage or even detachment. This is particularly true for hair clips and hair ties, where the clamping force of the hair clip arms couples with the inertial force of the magnetic module, and the elastic band's stretching and contracting movement conflicts with the need for fixation by the magnetic base. Existing technologies do not provide an effective anti-slip solution.

[0005] Third, the curvature adaptation range is narrow. The curvature of the wearing surface varies significantly among different types of headwear: the curvature radius of the forehead area of ​​headbands is approximately 55-65mm (corresponding to the common head circumference of adult women, 54-58cm), headbands have an almost flat structure (curvature radius approaching infinity), hair clips have a linear clamping structure, and hair ties have a ring-shaped curved surface (curvature radius approximately 30-50mm). Existing magnetic interfaces lack an effective curvature adaptation structure, making it impossible to achieve stable contact and reliable magnetic attraction with surfaces of various curvatures under the same interface standard.

[0006] Fourth, the sealing is not perfect. Existing fragrance control mechanisms mostly use stepped adjustment with aligned / misaligned grid holes. In the closed state, they rely on hole misalignment rather than surface contact sealing, resulting in slight leakage. At the same time, the magnetic coupling area lacks an effective sweat and oil barrier. During exercise, sweat seeps into the magnetic interface, leading to decreased magnetic force, corrosion of metal parts, and unpleasant odors caused by the mixing of essential oils and sweat.

[0007] Fifth, the protective system is lacking. Essential oils are corrosive to ordinary plastics, silicone, and elastic fibers, and long-term contact can lead to material aging, yellowing, and breakage; sweat and oil seeping into the headwear can cause mold growth. Although existing technologies have sealing structures, they lack system-level protective designs specifically for "essential oil isolation" and "sweat aging prevention."

[0008] In summary, existing technologies lack a standardized magnetic fragrance interface system that can be used across four categories: headbands, hair clips, and hair ties. This makes it impossible to achieve a user experience of "one fragrance module, multiple headwear carriers, and free switching between scenarios," and also makes it impossible to establish an effective patent barrier to prevent competitors from replicating the "one chip for four products" business model. Summary of the Invention

[0009] The purpose of this invention is to provide a universal magnetic fragrance interface system that can be used across different product categories, which solves the technical problems of existing magnetic fragrance headwear such as limited product categories, insufficient wearing stability, narrow curvature adaptation range, and imperfect sealing. This system enables the same fragrance module to be stably interchangeable and worn across multiple headwear categories.

[0010] To achieve the above objectives, the present invention adopts the following technical solution: A cross-category universal magnetic fragrance interface system includes a headwear carrier and a detachable fragrance module. The headwear carrier is selected from at least two of headbands, hair ties, hair clips, and hair rings. Each headwear carrier has a pre-embedded magnetic base. The pre-embedded magnetic base has a first magnetic element embedded in it, forming a standardized magnetic coupling surface. The detachable fragrance module includes a module housing, a second magnetic element disposed on the bottom surface of the module housing, and a fragrance release adjustment mechanism. The second magnetic element cooperates with the standardized magnetic coupling surface to form a magnetic connection. At least one of the pre-embedded magnetic base or the detachable fragrance module has an anti-misalignment positioning structure. The anti-misalignment positioning structure includes asymmetrically arranged positioning pins and positioning holes to restrict the circumferential rotational freedom of the detachable fragrance module relative to the pre-embedded magnetic base. At least one of the detachable fragrance modules is provided with an anti-loosening mechanical locking structure, which includes an elastic buckle and a slot, for providing a mechanical holding force perpendicular to the magnetic direction on the basis of magnetic attraction; the pre-embedded magnetic base is provided with an anti-slip bonding structure, which includes an elastic bonding layer and an anti-slip texture layer. The thickness of the elastic bonding layer is 0.5-2mm, and the anti-slip texture layer is a grid-like or dot-matrix raised layer, for enhancing the bonding stability between the pre-embedded magnetic base and the headdress carrier; the detachable fragrance module is provided with a fully sealed fragrance chamber, which includes a main sealing ring for the chamber body, a top cover sealing gasket, and a closing sealing surface. When the detachable fragrance module is in the closed state, the closing sealing surface forms a surface contact seal with the top cover, reducing the fragrance evaporation to less than 5% of the maximum evaporation.

[0011] Preferably, the standardized magnetic coupling surface includes three magnetic contacts, which are arranged in an isosceles triangle with a base length of 15-25mm and a leg length of 18-30mm.

[0012] Preferably, the pre-embedded magnetic base is provided with an arc adaptation structure, which includes at least one of an elastic pad and an adjustable arc support pad. The thickness of the elastic pad is 1-4mm, and the elastic pad is provided with an arc-shaped bottom surface that is pre-adapted to the curvature of the headdress carrier surface, so that the same standardized magnetic coupling surface can be adapted to different headdress carrier surfaces with curvature radii of 30-70mm, and ensure that the normal component of the magnetic attraction force remains stable on different arc surfaces.

[0013] Preferably, the headwear carrier is a headband, the embedded magnetic base is a silicone headband integrally injection molded embedded magnetic magnet, the magnetic magnet is fully covered by silicone to form a coating layer, the coating layer thickness is 1-3mm, and the anti-slip bonding structure is disposed between the coating layer and the silicone headband body.

[0014] Preferably, the headdress carrier is a hairband, the pre-embedded magnetic base is a hidden magnetic groove pre-embedded on the inner side of the webbing, and the anti-slip bonding structure is an anti-slip silicone edge set on the edge of the magnetic groove.

[0015] Preferably, the headdress carrier is a hair clip, the pre-embedded magnetic base is a clamp body with a reserved magnetic docking position, and the anti-slip bonding structure is an anti-slip micro-protrusion texture set on the surface of the magnetic docking position.

[0016] Preferably, the headdress carrier is a hair tie, the pre-embedded magnetic base is a sewn magnetic backing, and the anti-slip bonding structure is an anti-slip adhesive dot matrix disposed between the magnetic backing and the hair tie fabric.

[0017] This invention also provides a method for installing a cross-category magnetic fragrance module, comprising the following steps: placing the detachable fragrance module close to the pre-embedded magnetic base of the headwear carrier, so that the second magnetic element and the first magnetic element automatically align and adsorb under magnetic force; during the magnetic adsorption process, the anti-misalignment positioning structure guides the detachable fragrance module to the correct circumferential position; continuing to press the detachable fragrance module until the anti-loosening mechanical locking structure generates locking feedback, thus completing the installation.

[0018] The present invention also provides the use of the above-mentioned cross-category universal magnetic fragrance interface system in the modular assembly of fragrance for head ornaments.

[0019] The beneficial effects of this invention are: First, it achieves cross-category universal interchangeability. Through a standardized magnetic coupling surface design, the same detachable fragrance module can be adapted to four types of headwear: headbands, hair clips, and hair ties. Users can freely switch between them according to their usage scenarios, significantly reducing the cost of using it in multiple scenarios. Compared to existing technologies where each category requires a separate fragrance module purchase, the universal design of this invention significantly improves user experience and cost-effectiveness.

[0020] Secondly, it significantly improves wearing stability. Through the design of the anti-slip fit structure, including the cushioning and energy absorption of the elastic fit layer and the friction enhancement of the anti-slip texture layer, it effectively solves the problem of magnetic modules slipping and falling off under dynamic conditions such as sweating during exercise and head movement. Differentiated anti-slip designs for different product categories (anti-slip rubber layer for headbands, silicone edge anti-slip for hairbands, micro-embossed anti-slip for hair clips, and rubber dot matrix anti-slip for hair ties) are all optimized for the specific force characteristics of each product category, ensuring positional stability under various wearing conditions.

[0021] Third, the curvature adaptation range is optimized. Through the design of the curvature adaptation structure, the combination of elastic pads and adjustable curvature support pads allows the same interface to adapt to various surfaces with curvature radii of 30-70mm (the curved shape of the headband forehead, the near-flat surface of the hairband, and the circular curved surface of the hair tie), covering most head sizes (corresponding to head circumferences of 52-60cm). The pre-adapted curved bottom surface of the elastic pads ensures that the normal component of the magnetic attraction remains stable within the common curvature range, avoiding magnetic attraction attenuation or local stress concentration caused by curvature mismatch.

[0022] Fourth, it achieves a fully sealed fragrance lock. Through a three-stage sealing system consisting of the main sealing ring of the chamber, the top cover sealing gasket, and the closing sealing surface, the fragrance evaporation is reduced to less than 5% of the maximum evaporation when closed. Compared to existing technologies with misaligned grille holes (which still result in 15-20% leakage), the sealing performance is improved by approximately 3-4 times. Simultaneously, the elastic sealing lip forms a sweat and oil barrier in the magnetic coupling area, preventing sweat from seeping into the magnetic interface during exercise.

[0023] Fifth, specific implementation plans are provided for four product categories. For each of the headbands, hair clips, and hair ties, differentiated pre-embedded structures were designed, including integrated silicone injection molding, hidden grooves on the inner side of the webbing, pre-reserved docking positions on the clip body, and sewn magnetic base plates. These designs maintain standardized interfaces while achieving organic integration with the structures of each product category. Attached Figure Description

Detailed Implementation

[0026] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1: Overall Layout of a Cross-Category Universal Magnetic Fragrance Interface System like Figure 1 As shown, this embodiment provides a cross-category universal magnetic fragrance interface system, including four types of headwear carriers and a unified detachable fragrance module ⑧. The four types of headwear carriers are headband carrier ①, hairband carrier ②, hair clip carrier ③, and hair tie carrier ④, each of which is provided with a pre-embedded magnetic base ⑤.

[0028] The headband carrier ① has a pre-embedded magnetic base ⑤ in the forehead area, and the first magnetic element ⑦ is encapsulated inside the silicone using a one-piece silicone injection molding process, with only the standardized magnetic coupling surface ⑥ exposed. The hairband carrier ② has a hidden pre-embedded magnetic base ⑤ on the inner side of the webbing, and the magnetic coupling surface is covered by the webbing material. The hair clip carrier ③ has a magnetic docking position on the inner side of the middle section of the clip arm. The hair tie carrier ④ has a magnetic backing sewn into the fabric interlayer.

[0029] The bottom surface of the detachable fragrance module ⑧ is equipped with a second magnetic element ⑨, which can magnetically engage with the standardized magnetic coupling surface ⑥ on any carrier. For example... Figure 1 As shown in the bottom view below, the second magnetic element ⑨ is arranged in an isosceles triangle on the bottom surface of the module, corresponding to and engaging with the first magnetic element ⑦ on the standardized magnetic coupling surface ⑥. Guided by the anti-misalignment positioning structure ⑩, the detachable fragrance module ⑧ can only be installed in the single correct circumferential position, avoiding reverse installation or misalignment. The anti-loosening mechanical locking structure ⑪ provides additional mechanical holding force on top of the magnetic attraction, preventing accidental detachment during dynamic wear.

[0030] Example 2: Standardized magnetic coupling surface and sealing structure like Figure 2As shown, the standardized magnetic coupling surface ⑥ includes three magnetic contacts arranged in an isosceles triangle. The base of the isosceles triangle is 20mm long, and the legs are 25mm long. This asymmetrical distribution, combined with the anti-misalignment positioning structure ⑩, includes a D-shaped positioning pin located at the midpoint of the base and a circular positioning pin located at the vertex. The cross-section of the D-shaped positioning pin is D-shaped (semi-circular + flat), and the cross-section of the circular positioning pin is circular. This combination of large and small, non-circular and circular positioning methods can achieve both rapid alignment (the flat surface of the D-shape provides rapid guidance) and ensure uniqueness (the circular shape provides precise positioning).

[0031] An anti-slip bonding structure ⑫ is positioned between the pre-embedded magnetic base ⑤ and the headwear carrier, comprising an elastic bonding layer ⑬ and an anti-slip textured layer ⑭. The elastic bonding layer ⑬ is a 1mm thick silicone layer that provides cushioning and energy absorption, absorbing micro-vibrations and impacts during wear. The anti-slip textured layer ⑭ consists of grid-like protrusions, each 0.3mm high with a grid spacing of 1mm, increasing the coefficient of friction on the contact surface to prevent slippage.

[0032] The elastic sealing lip ⑯ is set around the standardized magnetic coupling surface ⑥, generating a compression of 0.5mm during magnetic engagement, forming an interface that isolates sweat and oil. The elastic sealing lip ⑯ is made of fluororubber or modified silicone, which has the characteristics of resistance to essential oil corrosion and sweat aging.

[0033] The curvature adaptation structure⑮ includes an elastic pad and an adjustable curvature support pad. The elastic pad is a 2mm thick silicone pad with a bottom surface that is pre-adapted to the curvature of the headwear carrier surface. The adjustable curvature support pad includes multiple support strips, the stiffness of which decreases along the direction away from the magnetic coupling surface, forming a flexible transition, allowing the same interface to adapt to different surfaces with curvature radii of 30-70mm.

[0034] Example 3: Detachable Fragrance Module Structure like Figure 3 As shown, the detachable fragrance module ⑧ includes a module housing, a second magnetic element ⑨, a fully sealed fragrance chamber ⑰, and a rotating stepless fragrance mixing mechanism ㉑.

[0035] The fully sealed fragrance chamber (17) includes a main sealing ring (18) for the chamber body, a top cover sealing gasket (9) and a closing sealing surface (9). The main sealing ring (18) is a silicone sealing ring with an O-shaped or X-shaped cross-section, installed in the annular groove between the fragrance chamber body and the top cover. The top cover sealing gasket (9) is an elastic silicone gasket, 1mm thick, adhered to the inner surface of the top cover. The closing sealing surface (9) is a precision-machined flat surface with a flatness ≤0.05mm. When the continuously variable fragrance mechanism (29) is adjusted to the closed position, the closing sealing surface (9) forms a surface contact seal with the top cover, reducing fragrance evaporation to below 3% of the maximum evaporation.

[0036] The rotary stepless fragrance mixing mechanism (29) includes a fragrance cap (20) and a fragrance cap mating surface. The fragrance cap (20) and the fragrance cap mating surface form a continuously variable ventilation cross-section through a conical fit, with a cone angle of 10 degrees. The fragrance cap (20) has a first ventilation groove, and the fragrance cap mating surface has a second ventilation groove. By rotating the fragrance cap (20), the overlapping area of ​​the first and second ventilation grooves is changed, allowing for stepless adjustment of the fragrance dispersion from 0-100%. When the fragrance cap (20) is rotated to the closed position, the bottom surface of the fragrance cap (20) and the fragrance cap mating surface form a surface contact seal. The contact pressure of the surface contact seal is provided by the pre-tightening force of the anti-loosening mechanical locking structure (11), further enhancing the sealing reliability.

[0037] An essential oil isolation and protective layer (23) is installed between the fragrance core compartment and the bottom surface of the module shell, including an isolation membrane resistant to essential oil corrosion. The isolation membrane is made of fluororubber and is 1mm thick, which can effectively prevent essential oil from penetrating into the magnetic element and headdress carrier, preventing material aging and corrosion.

[0038] Example 4: Differentiated Design of Four Types of Anti-slip Adhesive Structures like Figure 4 As shown, the anti-slip fit structure ⑫ adopts differentiated specific designs based on the stress characteristics and wearing methods of different product categories: For the headband carrier ①, an anti-slip fit structure ⑫ is provided between the rubber coating layer and the silicone headband body. The rubber coating layer is 2mm thick, and the contact surface between the rubber coating layer and the headband body has a grid-like anti-slip texture layer ⑭ with a grid depth of 0.2mm. The elastic deformation of the rubber coating layer can absorb the bending stress when the headband is worn, while the anti-slip texture prevents the rubber coating layer from slipping relative to the headband body during repeated bending.

[0039] For the headband carrier ②, the anti-slip fitting structure ⑫ is an anti-slip silicone edge set at the edge of the magnetic groove. The edge is 3mm wide and has longitudinal anti-slip stripes on its surface. When the headband is worn, the edge is in direct contact with the scalp, using the natural friction between silicone and skin to prevent the headband from slipping, while the hidden design of the magnetic groove keeps the appearance neat.

[0040] For the hair clip carrier ③, the anti-slip bonding structure ⑫ consists of anti-slip micro-protrusions on the surface of the magnetic docking position. The micro-protrusions are hemispherical protrusions, 0.5mm in diameter and 0.2mm in height, arranged in an array. These micro-protrusions increase the coefficient of friction between the magnetic module and the hair clip arm, while their small size does not affect the hair clip's clamping function or the smoothness of its appearance.

[0041] For the hair tie carrier ④, the anti-slip bonding structure ⑫ is an anti-slip adhesive dot array placed between the magnetic base and the hair tie fabric. The adhesive dots are circular silicone dots, 2mm in diameter and 0.5mm in height, distributed in a quincunx pattern. The adhesive dots utilize the viscoelasticity and surface adhesion of silicone to prevent the magnetic base from slipping circumferentially within the hair tie fabric. At the same time, the flexible dot array structure does not affect the hair tie's elasticity and wearing comfort.

[0042] Example 5: Installation method of cross-category magnetic fragrance module This embodiment provides an installation method for a cross-category magnetic fragrance module, applicable to the cross-category universal magnetic fragrance interface system as described in any one of claims 1-18.

[0043] Step 1: Preparation. Take the detachable fragrance module ⑧ and the headwear carrier (headband carrier ①, hair tie carrier ②, hair clip carrier ③, or hair ring carrier ④) that is already worn or to be worn. Ensure that the surface of the pre-embedded magnetic base ⑤ on the headwear carrier is clean and free of sweat, oil, or foreign matter.

[0044] Step Two: Initial Alignment. Place the detachable fragrance module ⑧ close to the pre-embedded magnetic base ⑤ of the headdress carrier, so that the second magnetic element ⑨ on the bottom of the module and the first magnetic element ⑦ on the base initially approach each other under magnetic force. At this time, the D-shaped positioning pin (large end) of the anti-misalignment positioning structure ⑩ first contacts the corresponding positioning hole, using the planar guiding characteristics of the D-shaped cross-section to guide the module into a roughly aligned position.

[0045] Step 3: Precise Positioning. Continue moving closer, and the circular positioning pin (small end) will enter the corresponding positioning hole, providing precise positioning. Because the three magnetic contacts are asymmetrically distributed in an isosceles triangle, the module can only be attracted in the single correct circumferential orientation. A 180° rotation or a 60° offset will prevent the positioning pin from entering the positioning hole, thus fundamentally preventing reverse installation or deflection.

[0046] Step 4: Magnetic Adsorption. Under the action of magnetic force, the second magnetic element ⑨ and the first magnetic element ⑦ automatically adhere to each other, generating an initial magnetic attraction force (approximately 1.5-3.0 kg). At this time, the elastic sealing lip ⑯ begins to contact the edge of the standardized magnetic coupling surface ⑥, generating initial compression.

[0047] Step 5: Mechanical Locking. Continue pressing the detachable fragrance module ⑧. The elastic buckle of the anti-loosening mechanical locking structure ⑪ slides along the guide slope into the slot until the hook engages with the locking recess, producing a perceptible click sound. At this point, the elastic sealing lip ⑯ reaches the designed compression amount (0.2-0.8mm), forming a complete sweat and oil barrier. Installation complete.

[0048] To remove the fragrance module, reverse the process: apply a pulling force perpendicular to the magnetic direction to overcome the mechanical holding force and magnetic attraction of the anti-loosening mechanical locking structure ⑪, and the detachable fragrance module ⑧ can be removed. Because the anti-loosening mechanical locking structure ⑪ is designed with a pulling force (approximately 3-5 kg) greater than the inertial force and vibration impact force during daily wear, it effectively prevents accidental dislodgement without being too tight to make manual removal difficult.

[0049] Example 6: Applications of a cross-category universal magnetic fragrance interface system This embodiment provides the application of the above-mentioned cross-category universal magnetic fragrance interface system in the modular assembly of fragrance for head ornaments.

[0050] The cross-category universal magnetic fragrance interface system of the present invention can be used in the following scenarios: Scenario 1: Multi-scene switching. Users wear headband carrier ① with detachable fragrance module ⑧ (emitting a light office fragrance) during their morning commute; switch to headband carrier ② (same module, sports-grade anti-sweat fragrance) during midday exercise; and change to hair clip carrier ③ (with the module's inner core replaced by a romantic fragrance) before an evening date. The same module can be used across three carriers, achieving "one core for three products."

[0051] Scenario 2: Shared Module Pool for Multiple Users. Multiple family members each own a headband / hair tie / hair clip / hair ring holder, but share a set of detachable fragrance modules. Based on the user's individual needs (fragrance preference, functional requirements such as mosquito repellent / cooling / antibacterial), the corresponding module core is selected and installed on the individual holder, significantly reducing the cost of family fragrance consumption.

[0052] Scenario 3: Seasonal Outfit Changes. Use hair tie carrier ④ (breathable and not stuffy) in spring and summer, and headband carrier ① (warm and covers the forehead) in autumn and winter. The same fragrance module can be switched with the season to avoid idle waste.

[0053] Scenario 4: B2B Gift Customization. Enterprise clients customize headbands / hair clips with brand logos as promotional gifts, and sell them as consumables along with standardized detachable fragrance modules⑧, establishing a business model of "carrier-driven traffic + module repurchase".

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
