Description

Technical Field

[0001] This invention relates to the field of nail product technology, and in particular to a nail device that attracts cat eyes. Background Technology

[0002] The core principle of cat-eye nail art is to add magnetic pigments that can be attracted by a magnetic field to the nail polish. When the nail polish is applied to the nail surface, the magnetic field causes the magnetic pigments in the polish to align in a specific direction, thus creating a cat-eye-like glossy effect. It can also present changing light and shadow effects at different angles.

[0003] The glass bead cat-eye effect is an innovative design in the current nail art industry. Its production principle is as follows: after evenly applying cat-eye gel polish to the nail surface, a small magnetic stick is held and rotated in a circle along the edge of the nail to make the magnetic pigment form a circular light-focusing effect, ultimately presenting a three-dimensional, rounded cat-eye luster similar to a glass bead, hence the name glass bead cat-eye effect.

[0004] However, creating a cat-eye effect with glass beads is quite challenging in practice. Firstly, the operator needs to draw a precise circular path using a magnetic stick. The roundness of this path directly determines the smoothness of the final glass bead effect; any deviation in the path will result in distortion and uneven light distribution. Secondly, the rotation speed of the magnetic stick also affects the final effect; a more stable and uniform rotation speed produces a more refined effect. These operations typically require professionally trained nail technicians. For ordinary users, creating a cat-eye effect with glass beads at home presents a significant challenge, making it difficult to achieve the desired results.

[0005] Previously, our development team applied for a patent for "A Cat-Eye Nail Stick" (application number CN202420286454.9). This solution can create a dynamic cat-eye effect, but it is difficult to consistently achieve a simplified glass bead cat-eye effect, requiring skilled operation from nail technicians. Therefore, there is an urgent need to develop a brand-new cat-eye suction device to lower the operational threshold for glass bead cat-eye nail art while ensuring consistency and refinement of the results.

[0027] Example Reference Figures 1 to 6 The present invention proposes a nail art device that attracts cat eyes, comprising: a housing 10, a magnetic suction component 20, and a rotary drive mechanism 30; The housing 10 is provided with an operating cavity 11 for supporting the manicure to be treated. The top of the housing 10 is provided with a light-transmitting operating area 12 that is vertically corresponding to the operating cavity 11. The light-transmitting operating area 12 is provided with a vertically penetrating viewing window. The magnetic suction assembly 20 includes a hollow rotating disk 21 and at least one magnet 22 mounted on the rotating disk 21. The rotating disk 21 is rotatably mounted on the top of the housing 10, and the hollow area of ​​the rotating disk 21 corresponds to the viewing window. The rotary drive mechanism 30 is used to drive the rotating disk 21 to rotate circumferentially, so as to drive the magnet 22 to rotate along a circular trajectory, and apply a rotating magnetic field to the nail polish coated with cat-eye gel polish placed in the operating cavity 11 to form a glass bead cat-eye effect.

[0028] The beneficial effects of this invention are: 1. Lowering the operational threshold and enabling zero-based operation: This invention replicates the circular drawing and magnetic action of professional nail technicians through a mechanical structure. Users only need to place the nail polish-coated nails into the operating cavity 11. No professional training or mastery of precise manual circular drawing techniques is required. Ordinary users can create professional-grade glass bead cat-eye nail art, completely breaking down the operational barriers of this nail art style.

[0029] 2. The magnetic attraction effect is stable and controllable, and the finished product is more refined. The rotating disk 21 drives the magnet 22 to rotate in a constant coaxial circle, avoiding problems such as hand tremors, trajectory deviation, and uneven speed during manual operation. The roundness of the rotation trajectory and the uniformity of the speed are far superior to those of handheld cat-eye stick operation. It can form a stable and uniform rotating magnetic field, making the magnetic pigment in the nail polish gel more regular. The final glass bead effect is round and full with uniform light focusing. Moreover, the consistency of the effect between batches is extremely strong, and the yield rate is much higher than that of manual operation.

[0030] 3. Strong functional expandability to meet diverse nail art needs. The magnetic component 20 adopts a replaceable modular disk design. Users do not need to replace the whole machine. They only need to replace the disks with different magnets 22 in terms of material, quantity, and arrangement to achieve different styles of cat-eye effects, which greatly improves the cost performance and functional expandability of the device.

[0031] Creating a glass bead cat's eye effect or other magnetic cat's eye effects refers to the effect produced by the nail technician's combination of magnets, rotation speed, stillness, and movement of the device, or other magnetic cat's eye effects not limited to glass bead cat's eye.

[0032] In some embodiments, the housing 10 includes an upper cover 13 and a lower cover 14; the operating cavity 11 is formed on the lower cover 14, and the light-transmitting operating area 12 is disposed on the upper cover 13; the upper cover 13 and the lower cover 14 are movably connected by a hinge, or the upper cover 13 is detachably connected to the lower cover 14. The split-type housing 10 structure, through the movable connection design of the upper and lower covers 14, realizes the opening and closing operation of the housing 10. Users can directly open the upper cover 13 to place and take out nail polish, providing a large operating space and convenient placement and retrieval, especially suitable for scenarios involving continuous operation of multiple nails; at the same time, the hinge or detachable connection design can adapt to different product positioning. The hinged opening and closing operation is more convenient and suitable for home scenarios, while the detachable connection facilitates cleaning and maintenance and is suitable for high-frequency use scenarios in professional nail salons, further improving the practicality and scenario adaptability of the device.

[0033] In some embodiments, the housing 10 is a one-piece housing structure, the operating cavity 11 is an open cavity located on the side of the housing 10, and the light-transmitting operating area 12 is located on the top of the housing 10 and communicates vertically with the open cavity. The one-piece housing structure, through the one-piece cavity design with side openings, greatly simplifies the structure of the housing 10, reduces assembly parts, and lowers mold opening and production costs.

[0034] In some embodiments, the rotating disk 21 is movably placed on the top surface of the housing 10 and can rotate circumferentially around the viewing window. The top surface of the housing 10 is provided with an annular limiting structure 15 coaxial with the rotating disk 21. The inner diameter of the annular limiting structure 15 is adapted to the outer diameter of the rotating disk 21, and is used to radially limit the rotating disk 21. The assembly method of placing the rotating disk 21 on the top surface, together with the annular limiting structure 15, realizes the non-embedded assembly of the rotating disk 21. Users can directly remove or replace the rotating disk 21, greatly improving the convenience of operation and perfectly adapting to the design of modular replaceable disks. At the same time, the annular limiting structure 15 can ensure that the rotating disk 21 always remains coaxial with the viewing window when rotating, avoiding radial offset during rotation, ensuring that the center of the rotating magnetic field coincides with the center of the nail art, and ensuring the roundness and uniformity of the glass bead effect. This not only meets the need for convenient replacement but also ensures the stability of the magnetic attraction effect.

[0035] In some embodiments, the rotating disk 21 is embedded within the light-transmitting operation area 12; the viewing window is a hollow window extending vertically, and the inner diameter of the rotating disk 21 is adapted to the outer diameter of the hollow window, allowing the rotating disk 21 to be rotatably embedded within the light-transmitting operation area 12. This embedded assembly method allows the rotating disk 21 and the housing 10 to form an integrated, compact structure, significantly reducing the overall size of the device and enhancing portability. Simultaneously, the embedded assembly precisely defines the rotation axis of the rotating disk 21, ensuring coaxiality and preventing displacement or jumping during rotation. This results in higher rotational stability, more precise speed control, further enhancing the refinement of the glass bead effect, and a cleaner overall appearance with no exposed moving parts, thus improving safety during use.

[0036] Furthermore, the mating point between the rotating disk 21 and the housing 10 is provided with bearings, balls, or grease. The design of bearings, balls, or grease significantly reduces the frictional resistance during the rotation of the rotating disk 21, making its rotation smoother and its speed more uniform and stable. This avoids speed fluctuations caused by jamming or uneven resistance, ensuring the uniformity of the rotating magnetic field and further improving the magnetic attraction effect. Simultaneously, the friction-reducing structure reduces wear on rotating parts, extends the device's service life, reduces noise during use, and enhances the user experience.

[0037] In some embodiments, the rotary drive mechanism 30 is an electric drive mechanism, including a motor 31, a control circuit board 32, a power supply unit, and a transmission assembly; the motor 31 is connected to the rotating disk 21 via the transmission assembly, and the control circuit board 32 is electrically connected to the motor 31 and the power supply unit, used to control the start, stop, direction, and speed of the motor 31; the transmission assembly includes a driving gear 33 and a driven gear 34 that mesh with each other; the driving gear 33 is fixed to the output shaft of the motor 31, and the driven gear 34 is a gear ring fixed to the outer circumference of the rotating disk 21; the power supply unit is a battery or an external power interface.

[0038] The specific solution for the electric drive mechanism, through the cooperation of motor 31, control circuit board 32, power supply unit and gear transmission components, realizes the automated drive of rotating disk 21, eliminating the need for manual operation and completely freeing the user's hands. The user only needs to start the device to automatically complete the magnetic attraction operation, further reducing the operation threshold. The control circuit board 32 can precisely control the start, stop, direction and speed of motor 31, which can adapt to different types of cat-eye nail polish gel and different effect requirements, and realize personalized parameter adjustment. The transmission design of the drive gear 33 and the outer circumferential gear ring of rotating disk 21 has a stable transmission ratio, no slippage in the transmission process, and uniform torque transmission, making the rotational stability of rotating disk 21 stronger and ensuring the constant uniformity of the rotating magnetic field. At the same time, the dual power supply design of rechargeable battery or external power supply adapts to different needs of portable use and fixed scene use, making the scene compatibility stronger.

[0039] In some embodiments, the rotary drive mechanism 30 is a manual drive mechanism, including a hand crank 35. The hand crank 35 is coaxially fixed to the rotating disk 21 or located on the outer periphery of the rotating disk 21, and the rotating disk 21 is driven to rotate circumferentially by human power. The design of the hand crank 35 achieves purely mechanical manual drive, requiring no power supply or electronic components, significantly simplifying the structure and reducing production costs, making it suitable for entry-level home products. Simultaneously, the manual drive allows users to independently control the rotation speed, rotation duration, and rotation direction of the rotating disk 21 according to their needs, adapting to personalized nail art effects and offering greater operational flexibility. Furthermore, the absence of electronic components enhances the device's waterproofness and durability, eliminating concerns about battery depletion, circuit failures, and other issues, resulting in a longer lifespan and greater portability, allowing for use anytime, anywhere without power supply limitations.

[0040] In this invention, the magnet 22 is any one or more of neodymium iron boron magnets, magnetic steel, ferrite magnets, rubber magnets, or electromagnets; the magnet 22 is any one or more of spherical, columnar, or cubic shapes; the magnet 22 is arranged oppositely or in parallel on the rotating disk 21; or, the magnet 22 is a composite magnetic group structure with multiple magnets stacked on the rotating disk 21; the magnetic attraction component 20 is a replaceable modular structure, and different magnetic attraction components 20 have magnets 22 arranged in different ways on the rotating disk 21 to form replaceable disks of different specifications.

[0041] The material, shape, arrangement, and modular design of the magnets 22 allow for compatibility with different magnetic permeability levels of cat-eye gel polish. Stronger magnets are suitable for polishes with lower magnetic permeability, while weaker magnets are suitable for polishes with higher magnetic permeability, preventing over- or under-magnetization. Different magnet shapes and arrangements create different magnetic fields, achieving various cat-eye effects and meeting diverse user needs. Furthermore, the replaceable modular disk design eliminates the need to replace the entire device; simply changing the disk allows for different cat-eye effects, significantly improving the device's scalability and cost-effectiveness while reducing user expenses.

[0042] In some embodiments, the housing 10 is provided with a curing lamp assembly 40; the curing lamp assembly 40 is disposed on the side of the light-transmitting operation area 12 opposite to the operation cavity 11, and is used to cure and set the cat-eye nail polish gel on the nail. By integrating the curing lamp with the magnetic attraction device, after magnetic attraction is completed, the housing 10 does not need to be opened, and the nail polish does not need to be moved. The curing lamp can be directly activated to irradiate and cure the nail polish through the light-transmitting operation area 12, avoiding the problem of displacement and disordered arrangement of the magnetic pigment caused by the disappearance of the magnetic field during the movement of the nail polish. It can perfectly lock the glass bead effect after magnetic attraction, greatly improving the yield and the refinement of the effect; at the same time, the integrated design eliminates the step of users preparing a separate curing lamp, making the operation process simpler and more convenient, further improving the integration and practicality of the device.

[0043] This invention, based on the magnetic properties of cat-eye gel polish, replicates and optimizes the manual magnetic attraction technique used by professional nail technicians through a mechanical structure, achieving a standardized and simplified production of the glass bead cat-eye effect. The working principle is as follows: Cat-eye gel polish contains flake-shaped magnetic pigments that can rotate freely within the liquid gel polish. When subjected to an external magnetic field, these pigments align in a specific direction along the magnetic field, creating a unique glossy effect. The core of the glass bead cat-eye effect is achieved by using a circular rotating magnetic field to evenly arrange the magnetic pigments within the gel polish along a circular trajectory, resulting in a rounded glass bead gloss with a central focus and naturally transitioning edges.

[0044] In use, the present invention first applies cat-eye gel polish evenly to the surface of the nail or nail tip, and then places the manicure with uncured cat-eye gel polish in the operating cavity 11 of the housing 10, so that the center of the manicure is coaxial with the light-transmitting operating area 12 at the top of the housing 10 and the hollow area of ​​the rotating disk 21; the rotating drive mechanism 30 is activated, and the rotating drive mechanism 30 drives the rotating disk 21 to rotate circumferentially around the axis. The magnet 22 fixed on the rotating disk 21 moves in a uniform circular motion synchronously with the rotating disk 21, thereby forming a uniform and stable rotating magnetic field with a fixed center at the operating cavity 11.

[0045] Under the influence of a rotating magnetic field, the magnetic pigments within the liquid nail polish on the nail surface are evenly oriented along a circular trajectory as the magnetic field rotates, forming a regular, rounded ring-shaped light-focusing effect, i.e., the glass bead cat-eye effect. After the magnetic pigments are arranged, the rotating drive mechanism 30 is turned off, and the nail polish can be directly irradiated and cured using a curing lamp through the hollow area of ​​the rotating disk 21 and the light-transmitting operation area 12, so that the arrangement of the magnetic pigments is permanently fixed, completing the creation of the glass bead cat-eye nail art. In the integrated curing lamp assembly 40 solution, the curing lamp assembly 40 on the housing 10 can be directly activated to complete the curing operation, without the need for additional curing equipment.

[0046] Compared to the manual operation of drawing circles with a magnetic rod, this invention ensures the absolute regularity of the rotation trajectory of the magnet 22 and the constant and uniform speed through a mechanical structure. It completely avoids problems such as hand tremors, trajectory deviation, and uneven speed during manual operation. It can produce a more rounded, uniform, and consistent glass bead cat's eye effect than manual operation. At the same time, no professional operating skills are required, and ordinary users can easily complete the operation.

[0047] Example 1 Please see Figures 1 to 3 This embodiment discloses a split-type electrically driven cat-eye nail art device, which is a preferred implementation method suitable for professional nail salons and home use.

[0048] This device includes a housing 10, a magnetic suction assembly 20, and an electric rotary drive mechanism 30. The housing 10 is divided into an upper cover 13 and a lower cover 14, which are hinged together to achieve a flip-top opening and closing. The top of the lower cover 14 has a recessed operating cavity 11 for supporting the manicure to be processed. The center of the operating cavity 11 has a marking position for positioning the manicure. The center of the upper cover 13 has a light-transmitting operating area 12, which is a circular viewing window that runs vertically through the center. The viewing window is coaxially aligned with the positioning marking position of the operating cavity 11.

[0049] The magnetic assembly 20 includes a hollow circular rotating disk 21 and two cylindrical neodymium iron boron magnets 22 fixed on the rotating disk 21. The outer diameter of the rotating disk 21 is adapted to the inner diameter of the viewing window, and the rotating disk 21 is rotatably embedded in the viewing window. The hollow area of ​​the rotating disk 21 corresponds coaxially with the viewing window. The four magnets 22 are symmetrically fixed to the rotating disk 21 with their north and south poles facing each other, and can rotate synchronously with the rotating disk 21. Food-grade grease is filled between the mating contact surfaces of the rotating disk 21 and the viewing window of the upper cover 13 to reduce rotational friction resistance and ensure smooth rotation of the rotating disk 21.

[0050] The electric rotary drive mechanism 30 is fixedly installed inside the upper cover 13 and includes a motor 31, a control circuit board 32, a rechargeable lithium battery, and a transmission assembly. The transmission assembly includes a meshing drive gear 33 and a driven gear ring. The drive gear 33 is fixedly installed on the output shaft of the motor 31, and the driven gear ring is integrally formed on the outer peripheral sidewall of the rotating disk 21. The control circuit board 32 is electrically connected to the motor 31 and the rechargeable lithium battery. The outer side of the housing 10 is provided with control buttons that are electrically connected to the control circuit board 32, which can realize the start and stop, speed adjustment, and forward and reverse rotation switching control of the motor 31. The rechargeable lithium battery provides power to the device, and the outer side of the housing 10 is provided with a Type-C charging interface connected to the lithium battery, which can realize cyclic charging.

[0051] The usage method of this embodiment is as follows: Pretreatment: Apply a layer of cat-eye gel polish evenly to the surface of the nail or nail tip, without curing; Positioning: Open the top cover 13 and place the nail art with uncured cat-eye gel polish in the operating cavity 11 of the bottom cover 14, aligning the center of the nail art with the positioning mark, and then close the top cover 13. Automatic magnetization: The motor 31 is started by the control button. The motor 31 drives the rotating disk 21 to rotate at a uniform speed through the meshing of the driving gear 33 and the driven gear ring. The magnet 22 on the rotating disk 21 moves in a coaxial circular motion with the rotating disk 21, forming a uniform rotating magnetic field at the nail art area. This causes the magnetic pigment in the nail polish to align in an orientation, forming a rounded glass bead cat-eye effect. Users can observe the magnetization effect in real time through the hollow area of ​​the rotating disk 21 and adjust the magnetization time. Curing and shaping: After magnetization is completed, motor 31 is turned off. The nail polish is then irradiated with ultraviolet curing lamp through the hollow area and viewing window of rotating disk 21 to cure the cat-eye nail polish, fix the arrangement of the magnetic pigments, and complete the creation of glass bead cat-eye nail polish.

[0052] Meanwhile, the magnetic suction component 20 in this embodiment is a replaceable modular structure. Users can replace the rotating disk 21 with different numbers of magnets 22 and different arrangements of magnets 22 according to their needs to achieve different styles of cat's eye effects.

[0053] Example 2 Please see Figures 4 to 6 This embodiment discloses an integrated, manually driven cat-eye nail art device, which is a low-cost implementation method suitable for beginners.

[0054] This device includes an integrated housing 10, a magnetic suction assembly 20, and a manual rotation drive mechanism 30. The integrated housing 10 is a one-piece injection molded structure. The side of the housing 10 has an open operating cavity 11, into which the user can directly insert their fingers to place nails. The bottom surface of the operating cavity 11 has an arc-shaped finger support to improve user comfort. The top of the housing 10 has a light-transmitting operating area 12, which is a circular viewing window that runs vertically through the housing. The viewing window is coaxially aligned with the finger support of the operating cavity 11.

[0055] The magnetic assembly 20 includes a hollow circular rotating disk 21 and a block-shaped ferrite magnet 22 fixed on the rotating disk 21. The rotating disk 21 is independently and movably placed on the top surface of the housing 10. The top surface of the housing 10 has an integrally formed an upwardly protruding annular limiting structure 15. The inner diameter of the annular limiting structure 15 is adapted to the outer diameter of the rotating disk 21, which can radially limit the rotating disk 21, ensuring that the rotating disk 21 rotates circumferentially around the axis of the viewing window without radial displacement. The hollow area of ​​the rotating disk 21 corresponds coaxially with the viewing window. The magnet 22 is fixed on the lower end face of the rotating disk 21, facing the side of the operating cavity 11. An annular ball groove is provided between the bottom surface of the rotating disk 21 and the top surface of the housing 10. Multiple stainless steel balls are evenly arranged in the ball groove to reduce the frictional resistance when the rotating disk 21 rotates, ensuring smooth rotation.

[0056] The manual rotation drive mechanism 30 is a hand crank 35 integrally formed on the outer periphery of the rotating disk 21. The hand crank 35 extends outward along the radial direction of the rotating disk 21. The user can rotate the rotating disk 21 circumferentially by holding the hand crank 35.

[0057] The usage method of this embodiment is as follows: Pretreatment: Apply a layer of cat-eye gel polish evenly to the nail surface, without curing; Positioning: Insert the finger coated with uncured cat-eye nail polish into the operating cavity 11 on the side of the housing 10 and place it on the arc-shaped support, so that the center of the nail is aligned with the axis of the viewing window. Manual magnetization: Hold the hand crank 35 and rotate the rotating disk 21 at a constant speed. This will cause the magnet 22 to make a coaxial circular motion around the nail, forming a rotating magnetic field. This will cause the magnetic pigments in the nail polish to align in an orientation, creating a glass bead cat's eye effect. Users can adjust the rotation speed and duration as needed and observe the magnetization effect in real time through the hollow area of ​​the rotating disk 21. Curing and shaping: After the magnetization is completed, stop rotating the rotating disk 21. Use an ultraviolet curing lamp to irradiate the nail through the hollow area and viewing window of the rotating disk 21 to cure the nail polish and complete the creation of the glass bead cat eye nail art.

[0058] The device in this embodiment has no electronic components, requires no power supply, has a simple structure, low production cost, and is easy to operate, making it very suitable for ordinary users at home. At the same time, different sizes of rotating discs 21 can be replaced to achieve different nail art effects.

[0059] Example 3 This embodiment discloses a cat-eye nail art device with an integrated curing lamp assembly 40, which is a preferred embodiment for convenient operation. The difference between this embodiment and Embodiment 1 is that the curing lamp assembly 40 is integrated onto the housing 10.

[0060] The curing lamp assembly 40 includes multiple ultraviolet LED beads, which are fixedly installed on the inner edge of the viewing window on the top of the housing 10. The light-emitting side of the beads faces the operating cavity 11 and can irradiate the nail art inside the operating cavity 11 through the viewing window and the hollow area of ​​the rotating disk 21. The curing lamp assembly 40 is electrically connected to the control circuit board 32. The housing 10 has a corresponding curing lamp control button on the outside, which can control the start and stop of the curing lamp and the irradiation duration.

[0061] The usage method of this embodiment is as follows: Pretreatment: Apply cat-eye gel polish evenly to the nail surface without curing; Positioning: Insert your finger into the operating cavity 11 and adjust the position of your nail so that the center of your nail is coaxially aligned with the viewing window; Automatic magnetization: Start motor 31 to drive rotating disk 21 to rotate at a constant speed. The rotating magnetic field formed by magnet 22 causes the magnetic pigment in the nail polish to align in an orientation, forming a glass bead cat's eye effect. After magnetization is complete, turn off motor 31. In-situ curing: Directly activate the curing lamp assembly 40. The curing light emitted by the ultraviolet lamp beads shines on the nail through the viewing window, curing the cat-eye nail polish in-situ. No need to move the finger, perfectly locking the magnetic effect. After curing, remove the finger to complete the glass bead cat-eye nail art.

[0062] This embodiment integrates the magnetic attraction function and the curing function, making the operation process simpler. It also avoids the displacement of the magnetic pigment during the movement, resulting in a higher yield and more refined effect, making it very suitable for home use.

[0063] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
