Description

Technical Field

[0001] This invention relates to pillows, specifically to a rare-earth magnetic graphene far-infrared spinal health pillow. Background Technology

[0002] Based on the principles of human anatomy and biomechanics during sleep, the inventor of this invention, using prior-authorized utility model patent ZL201720864404.4, scientifically divides the body into seven independent functional zones. Each zone is separated by strips of fabric, forming a relatively enclosed independent cavity. Differentiated elastic fibers are used for filling, and reasonable height differences are set: the neck support zone for left and right lateral positions is higher than that for supine positions, adapting to the physiological characteristic of the shoulders naturally rising when lying on one's side, effectively avoiding cervical spine scoliosis; the occipital support zone for supine positions and the temporal support zone for left and right lateral positions adopt a low-elasticity, low-height design, precisely matching the pressure requirements of different parts of the head and neck; the pillow position stabilization zone is filled with heavy particles, effectively ensuring that the pillow position does not shift during sleep, reducing the occurrence of stiff neck and cervical spine torsion and deformation.

[0003] Following the prior patent application date, the inventor has successively disclosed a large number of similar health and wellness bedding-related patent technologies, including seven-zone ergonomic pillow structure, layered support pillow, graphene far-infrared therapy pillow, carbon fiber heating therapy products, and rare earth magnetic therapy health and wellness equipment, among other technical solutions.

[0004] Some of these patents replicate the seven-zone pillow layout, simply imitating the external zoning structure without a systematic inner composite health and wellness structure; some patents disclose layered filling pillow designs, simply using conventional soft and hard materials stacked together without setting precise ratio ranges based on biomechanics; and many other patents apply graphene and far-infrared heating technology to the pillow body, only achieving basic heating radiation function without constructing a secondary excitation amplification and synergistic empowerment system.

[0005] Several patents related to health pillows with built-in negative ion generators have been disclosed in the existing technology, with typical examples including CN106213915A, CN105877337A, CN206964466U, and CN203953135U. Among them, CN106213915A integrates a negative ion generator and an ultrasonic mosquito repellent module inside the pillow body; CN105877337A generates negative ions by using a charging module with a dedicated boost circuit and a transmitter; CN206964466U adopts a head-press trigger-type start-up structure; and CN203953135U integrates a traditional negative ion generator and a carbon fiber emitting electrode into the pillow body.

[0006] Most of the aforementioned published patents employ the traditional high-voltage corona discharge negative ion generation mode. This requires a dedicated high-voltage boost module to generate a high-voltage electric field of several thousand volts, relying on the electrode tips to ionize the air and produce negative oxygen ions. This technology has several inherent drawbacks. When used close to the head and neck for extended periods, the built-in high-voltage circuitry poses a risk of leakage and electromagnetic radiation, creating significant safety hazards for long-term home use. Furthermore, the high-voltage discharge process easily generates harmful byproducts such as ozone and nitrogen oxides, which are continuously released in the closed bedroom environment, negatively impacting respiratory health. The entire high-voltage generation system is complex, including a high-voltage mainboard, intricate circuitry, dedicated emitting electrodes, and control components. The assembly structure is cumbersome, resulting in high manufacturing costs. Daily pressure and bending of the pillow can cause circuit aging, poor contact, and equipment failure, leading to a short overall lifespan. Some systems rely on head pressure to trigger the release of negative ions, resulting in a weak and highly fluctuating output concentration that cannot be maintained stably and effectively over a long period, leading to poor practical results. Meanwhile, this type of negative ion pillow has a single function, only independently releasing negative ions. It is not equipped with a professional far-infrared therapy system, rare earth composite magnetic array, or zoned ergonomic support structure. The various functions are independent of each other without a linkage mechanism, and there is no multi-dimensional synergistic health care principle. The technology system is crude and simple.

[0007] Among magnetic therapy and wellness technologies, CN202511537176.5, a rare-earth permanent magnet graphene composite magnetic therapy mat, is relatively close. Although this solution combines rare-earth permanent magnet materials with graphene far-infrared technology, its overall technical design is rather superficial and rudimentary. This device simply uses rare-earth permanent magnets scattered and laid out without incorporating rare-earth soft magnetic materials for combination, failing to form a composite magnetic circuit system with complementary magnetic potentials, and also failing to use a topological array method to organize the magnetic field lines. This scattered, single-point placement of magnets easily results in a chaotic and disordered magnetic field distribution, significant differences in regional magnetic field strength, weak magnetic field penetration, a narrow effective range, excessively high magnetic field strength at close range, and rapid attenuation and dissipation of the magnetic field at locations far from the magnets, failing to form a uniform, long-lasting, stable, and deeply penetrating steady-state therapeutic magnetic field.

[0008] Meanwhile, the existing technology only achieves a simple combination of graphene heating and single-point magnetic therapy, without a negative ion release health care system, without a synergistic mechanism for far-infrared directional activation of negative ions, without a dedicated gradient layered support structure for the head and neck, and even less with a seven-zone precise ergonomic design to adapt to various sleeping positions. The overall technical solution has a single function and a crude health care mode, and cannot specifically address the actual pain points in the industry such as cervical spine alignment and maintenance, deep calming and sleep aid, and long-term conditioning of human microcirculation.

[0009] However, the inventor's original patent still has the following technical shortcomings: 1. The first layer of the original patent uses a far-infrared conversion layer with a specific wavelength, which only has a single wavelength conversion function and no negative ion health and wellness enhancement, resulting in a single functional dimension; the second layer is a conventional heating emission source with a wide range of noise and low emissivity, insufficient flexibility, and significant long-term attenuation, and it lacks a synergistic structure for light wave-excited negative ions, thus limiting the health and wellness benefits. According to relevant research literature, graphene can stably emit far-infrared light waves of 7-14μm. This band is highly compatible with the core range of human infrared radiation of 8-14μm, and it is easy to resonate with human tissues. It has good subcutaneous penetration effect and its far-infrared emission performance is significantly better than that of traditional materials such as carbon crystal and carbon fiber.

[0010] Existing publicly available medical and health research data clearly recognizes that negative ions have a definite regulatory effect on the human body: For the nervous system, they can calm the nerves, relieve tension and anxiety, improve difficulty falling asleep, and enhance the quality of deep sleep; for the respiratory system, they can purify air particles, moisturize the respiratory mucosa, and soothe throat and airway discomfort; for the cardiovascular system, they can help regulate peripheral microcirculation, relieve vascular stress, and stabilize the body's metabolic rhythm; simultaneously, they can positively regulate the body's immune function, enhance physiological anti-fatigue ability, and improve the body's homeostasis. The World Health Organization (WHO) stipulates that the standard for fresh air negative ions is ≥1000–1500 ions / cm³, while the domestic health environment standard requires ≥3000 ions / cm³. Clinical studies have confirmed that high concentrations of negative ions can significantly improve sleep structure. Reference: World Health Organization (WHO). Air Quality Guidelines (Fourth Edition) [S]. Geneva: WHO Press, 2021.

[0011] In nature, negative ions generally exhibit spontaneous decay and charge annihilation phenomena. The main mechanisms of their extinction include the neutralization of positive and negative ion charges, adsorption and sedimentation of suspended particulate matter in the air, and consumption through oxidation reactions with harmful gases. Their lifespan is greatly affected by the environment. In ordinary urban indoor environments, the lifespan of negative ions is only 30 to 300 seconds, and as low as 0.1 to 3 seconds in polluted environments. Even in clean environments such as forests and waterfalls, the lifespan is only 3 to 10 minutes. At the same time, negative ions decay extremely quickly in space, and their concentration drops sharply with increasing diffusion distance. Under natural conditions, it is impossible to maintain an effective health-preserving concentration in a fixed area for a long time.

[0012] Conventional negative ion smart substrates and ordinary negative ion home textile composite layers, although capable of passively releasing negative ions, suffer from inherent defects due to the natural attenuation, charge annihilation, and dilution characteristics of negative ions by airflow diffusion: negative ions drift freely in open spaces and are rapidly diffused, attenuated, and annihilated by indoor air convection and airflow, failing to form a continuous, stable, and effective health-promoting concentration around the human mouth and nose; even in a closed room environment, it is difficult to naturally accumulate to form a concentration of negative ions that can be effectively inhaled by the respiratory system, thus rendering its inherent effects such as nerve calming, respiratory regulation, cardiovascular microcirculation regulation, and immune enhancement ineffective, resulting in products with functions that are merely formal and have extremely low practical application value.

[0013] 2. The original patented head and neck key support area uses a single high-elastic fiber as the whole filling, without an upper and lower layered structure, which cannot simultaneously achieve the layered force distribution design of strong lower support and soft upper body fit. It is difficult to balance support hardness and comfort. According to relevant biomechanical research, a pillow height deviation of 2cm can lead to abnormal cervical curvature and an increase in intervertebral disc pressure of 40-60%. Layered support can effectively optimize the distribution of head and neck force. References: Zhang Lei, Chen Yang, Liu Min. Biomechanical design and optimal height ratio of cervical pillow[J].

[0014] 3. The original patented magnetic therapy structure uses ordinary soft magnetic materials in a simple and irregular flat arrangement, resulting in a scattered magnetic field, disordered magnetic lines of force, large fluctuations in strength, significant temperature drift, easy attenuation, and insufficient depth penetration. The stability and long-term effectiveness of the magnetic therapy are both significantly lacking. Biomagnetic research shows that a static magnetic field of reasonable intensity can promote local blood circulation and relieve muscle tension and fatigue. The composite arrangement of rare earth permanent magnets and soft magnets can significantly improve the uniformity of the magnetic field and the depth of spatial penetration.

Summary of the Invention

[0015] The purpose of this invention is to provide a rare-earth magnetic graphene far-infrared spinal health pillow. While retaining the existing proprietary patent structure, it makes targeted and substantial iterative upgrades and improvements to address the technical shortcomings of the original patent, such as single function, weak emission source performance, easy decay and annihilation of natural negative ions, insufficient concentration and ineffectiveness of conventional products, unreasonable filling ratio without layering, and insufficient performance of the magnetic therapy system. At the same time, it is different from existing similar patents that simply replicate the structure, replace materials, or add functions. All technical improvements are supported by national standards, professional journals, and biomechanical literature, and the technological advancement and practicality are clear.

[0016] The technical solution of this invention is: a rare-earth magnetic graphene far-infrared spinal health pillow, the pillow body is designed according to human anatomy and biomechanics, and the pillow body is divided into seven independent functional areas, including a supine neck support area, a right lateral neck support area, a left lateral neck support area, a right lateral temporal face support area, a left lateral temporal face support area, a supine occipital support area, and a pillow body position stabilization area; its characteristic is: below the biomimetic curved support layer of the supine neck support area, there is a composite negative ion health function layer, a far-infrared emission source layer, a support filling layer, and a magnetic therapy composite array layer from top to bottom; the supine neck support area is provided with an airbag structure for independently inflating and deflating to adjust the height of the pillow body.

[0017] The biomimetic curved support layer is a topological arc surface configuration adapted to the physiological curves of the human cervical and thoracic vertebrae; the negative ion health care function layer is made of negative ion composite fiber material; the far-infrared emission source layer is any one of graphene, carbon crystal, or carbon fiber with far-infrared emission function as an active carbon substrate layer; the magnetic therapy composite array layer is made of neodymium iron boron rare earth permanent magnet material and is arranged in any one of the following dot matrix arrangements: matrix, honeycomb, ring, or staggered.

[0018] The negative ion health and wellness functional layer includes a heat emission source and a negative ion functional composite substrate layer. The heat emission source uses graphene as the optimal steady-state temperature field supply source, and alternative materials with equivalent heat field efficiency, such as carbon crystal, carbon fiber, and electric heating wire, can also be used. A constant steady-state radiation temperature field is generated by the graphene emission source or other equivalent heating medium, forming a temperature field coupling intelligent energy-enabling system with the negative ion functional composite substrate layer. The steady-state temperature field polarization activates the functional fibers inside the substrate, realizing the continuous, balanced, and long-lasting release of negative ion health and wellness energy.

[0019] The far-infrared emission source layer includes a heating emission source and a far-infrared resonant functional substrate layer, with the heating emission source located below the far-infrared resonant functional substrate layer. The heating emission source uses graphene and also includes, but is not limited to, any one of the following functional media with equivalent infrared radiation performance: carbon crystal, carbon fiber, or heating wire. A basic far-infrared light wave field is generated by the lower graphene or other equivalent heating medium, and then resonates, superimposes, excites, and optimizes the spectrum of the upper far-infrared resonant functional substrate layer to achieve far-infrared energy concentration amplification and deep penetration therapy.

[0020] The supporting filling layer is optimized into an upper and lower layered structure, with the upper part using a soft, low-elasticity buffer filling material and the lower part using a high-elasticity fiber material composite arrangement. The equivalent ratio range is limited to 1 / 6 to 1 / 4 for the upper layer and 3 / 4 to 5 / 6 for the lower layer.

[0021] The magnetic therapy composite array layer is a rare earth magnetic topology array, which uses rare earth permanent magnets and rare earth soft magnets as the optimal combination and is combined according to the magnetic circuit topology configuration. Through the mutual topological arrangement of permanent magnets and soft magnets, the magnetic potential complementarity, and the magnetic field line convergence magnetic field configuration, a stable health and wellness physiological magnetic field with directional uniform magnetic field, magnetic energy concentration, and uniform penetration is formed.

[0022] The pillow body may also include a layer of mugwort, a layer of agarwood, a layer of bamboo charcoal purification, a height adjustment buckle, a side ventilation channel, a removable inner liner, and external storage accessories.

[0023] The pillow body is either an integral structure or a detachable modular structure, and may include additional ventilation grooves, height adjustment components, a medicated filling layer, and a removable pillowcase.

[0024] Advantages of this invention: First, the specific wavelength far-infrared conversion layer in the supine neck support area of ​​the original patent has been removed and replaced with a negative ion health and wellness functional layer. The equivalent range of negative ion release concentration in the substrate is set to 1500-3000 ions / cm³, and the far-infrared normal emissivity is not less than 85%. Existing public literature and industry consensus confirm that negative ions have mature and clear human health and wellness mechanisms: acting on the nervous system, they can calm the central nervous system, relieve emotional anxiety, shorten the time to fall asleep, and improve the quality of deep sleep; acting on the respiratory system, they can purify suspended particles in the microenvironment around the mouth and nose, moisturize the airway mucosa, and relieve respiratory sensitivity and discomfort; acting on the cardiovascular system, they can improve peripheral blood microcirculation, relieve vascular tension, and stabilize the body's metabolic rhythm; at the same time, they can positively regulate the body's immune function, enhance anti-fatigue ability, and promote physiological self-repair homeostasis.

[0025] Secondly, this invention uses active graphene far-infrared light waves to physically excite the negative ion substrate to release negative ions, completely abandoning the traditional method of generating negative ions through high-voltage corona discharge and high-voltage breakdown air ionization. It eliminates the risks of high-voltage leakage, high-voltage breakdown, electromagnetic radiation, and harmful byproducts such as ozone and nitrogen oxides from the structural source, making it safer, more environmentally friendly, and more suitable for long-term close-fitting use on the head and neck during sleep. At the same time, it avoids the defects of traditional high-voltage circuits, such as complexity, easy damage, short lifespan, and high cost, resulting in a simpler structure, more stable performance, and longer service life.

[0026] Third, the substrate is placed at the core of the head and neck pillow, close to the human body's mouth and nose breathing area. The far-infrared light waves radiated by the lower graphene nanoscale far-infrared excitation source layer can irradiate upwards in a directional manner, activating the polarization efficiency of the internal fibers of the composite substrate. This breaks through the environmental conditions that limit the natural release of negative ions, greatly improving the concentration, activity and long-term stability of negative ions, and offsetting the natural decay and annihilation loss of negative ions.

[0027] Fourth, the substrate simultaneously generates far-infrared secondary radiation upon stimulation, achieving a synergistic effect of far-infrared therapy and negative ions, resulting in a synergistic benefit greater than the sum of its parts. Compared to conventional negative ion substrates, which are prone to free dispersion in open spaces, rapid decay and annihilation, and difficulty in forming an effective inhalation concentration, rendering various health benefits ineffective, this invention employs a unique structure of close-range, body-hugging placement combined with infrared directional stimulation. This effectively counteracts the natural decay, annihilation, and diffusion loss of negative ions, allowing them to stably converge in the small breathing area around the mouth and nose without large-scale spatial diffusion loss. During nighttime sleep, the body can continuously and directly inhale high concentrations and highly active negative ions, enabling the inherent health benefits of negative ions in areas such as nerve-aiding sleep, respiratory regulation, cardiovascular microcirculation, and immune regulation to be truly, stably, and efficiently realized. This synergistic system has not been disclosed in existing similar subsequent patents.

[0028] Fifth, the conventional far-infrared emitting layer of the original patent is directly replaced with a graphene nanoscale far-infrared excitation source layer. According to GB / T 18319-2019, T / CGIA 006-2024 standards and research literature on graphene textile materials, graphene natively emits far-infrared wavelengths of 7-14μm, with a pure spectrum, concentrated energy, and an excellent proportion of effective therapeutic wavelengths. The far-infrared normal emissivity can reach over 88%, and the heating is uniform without local hot spots. The material is thin, flexible, and can be fully installed to fit the curved surface of the pillow. The long-term working power attenuation is extremely low, and the service life is far superior to traditional heating materials, with more prominent therapeutic effects through resonance.

[0029] Sixth, the support filling layer is optimized into a two-layer structure. The upper layer uses a soft, low-elasticity cushioning filling material, while the lower layer uses a composite of high-elasticity fiber materials. The equivalent ratio range is limited to 1 / 6 to 1 / 4 for the upper layer and 3 / 4 to 5 / 6 for the lower layer. The optimal volume ratio is 1 / 5 and 4 / 5. The lower high-elasticity layer serves as the basic load-bearing layer, providing rigid support and maintaining the physiological curvature of the cervical spine. The upper soft cushioning material serves as the body-contact layer, providing flexible cushioning, pressure relief, and skin-friendly effects. This significantly improves the fit and long-term sleep comfort while ensuring that the support does not diminish.

[0030] Seventh, abandoning the irregular and simple flat magnetic therapy layer of ordinary magnetic materials in the original patent, the optimal combination of rare earth permanent magnets and rare earth soft magnets is preferred, and then arranged in an alternating manner according to the magnetic circuit topology to form a uniform magnetic permeability composite magnetic array; at the same time, it is compatible with neodymium iron boron permanent magnets, plastic flexible soft magnets, magnetic adhesives and other magnetic materials with the same effect; by utilizing the complementary advantages of the two types of magnetic materials, the magnetic field arrangement is regulated and the direction of magnetic lines of force is straightened; effectively solving the shortcomings of traditional ordinary magnetic materials such as scattered magnetic field, fluctuation in strength due to sleeping posture deviation, significant environmental temperature drift, easy magnetic attenuation, and weak depth penetration; constructing a stable three-dimensional composite magnetic field with full coverage, uniform strength, good temperature stability, resistance to attenuation, and strong depth penetration, greatly improving the stability, long-term effect and therapeutic depth of magnetic therapy.

[0031] Eighth, it fully retains the original patent's seven functional zones layout, the height difference design of each zone, and the ergonomic advantages of side-lying with shoulder elevation. The elastic filling and height-to-low ratio logic of each zone remain unchanged. It also retains the original airbag layer structure, which can flexibly adjust the local height of the pillow body by inflating and deflating the airbag, adapting to the personalized support needs of users with different heights, body types, and cervical spine conditions, making it more universal. It does not require changes to the shape mold and airbag installation structure, making it highly industrializable.

[0032] Ninth, the four improvements are clearly defined and progressively implemented: First, rare-earth magnetic materials are selected as the optimal combination for the magnetic assembly, while also providing a backup of equivalent magnetic materials. Second, graphene is selected as the optimal emission source for far-infrared and negative ion temperature fields, while also being compatible with other equivalent heating media. Third, a new multi-system health and wellness dimension for negative ions is added, achieving synergistic effects with light waves. Simultaneously, the core pain points of natural attenuation and annihilation of negative ions, insufficient concentration in traditional products, and ineffective efficacy are addressed through a close-fitting design and infrared excitation. Fourth, the graphene nano-level far-infrared excitation source layer is upgraded, resulting in a purer spectrum, higher emissivity, and greater flexibility and durability. Fifth, the upper and lower layered filling structure of the head and neck support area is optimized, with a strong support and shaping lower layer and a flexible, close-fitting upper layer. The cushioning completely solves the drawbacks of single filling not being able to balance support and comfort; the reconstructed uniform magnetic and magnetically conductive composite magnetic array makes the magnetic field more uniform, stable, durable, and penetrating deeper; all improvements are concentrated on the four core modules of the inner intelligent composite substrate, the newly added health and wellness function, the far-infrared emission source material, the layered arrangement and ratio of filling, and the magnetic material array, without changing the external structure, the partition shape, or the original adjustment function of the airbag. The improvement boundaries are clear, the new functions are well-defined, the mechanism of action is supported by public research and physical properties, and the practical application value is outstanding. Compared with the existing simple replication and superimposed later patents, it has outstanding creativity and significant technological progress. Attached Figure Description

Detailed Implementation

[0034] The technical solution of the present invention will be further described below with reference to the accompanying drawings, but it should not be construed as a limitation on the technical solution.

[0035] like Figure 1 , 2As shown, a rare-earth magnetic graphene far-infrared spinal health pillow is designed based on human anatomy and biomechanics. The pillow body is divided into seven independent functional zones, including a supine neck support zone 1, a right lateral neck support zone 2, a left lateral neck support zone 3, a right lateral temporal facial support zone 4, a left lateral temporal facial support zone 5, a supine occipital support zone 6, and a pillow body position stabilization zone 7. Its characteristic feature is that, below the biomimetic curved support layer 8 of the supine neck support zone, from top to bottom, there are sequentially arranged a negative ion health function layer 9, a far-infrared emission source layer 10, a support filling layer 11, and a magnetic therapy composite array layer 12; the supine neck support zone 11 is equipped with an airbag 13 for height adjustment.

[0036] The biomimetic curved support layer is a topological arc structure adapted to the physiological curves of the human cervical and thoracic vertebrae; the negative ion health and wellness functional layer is made of negative ion composite fiber material; the far-infrared emission source layer is made of one of the carbon far-infrared emission substrates, namely graphene, carbon crystal or carbon fiber; and the magnetic therapy composite array layer is made of neodymium iron boron rare earth permanent magnet material to form a topological array structure.

[0037] The negative ion health care functional layer is composed of a heat emission source and a negative ion functional composite substrate layer. The heat emission source is one of graphene, carbon crystal, carbon fiber or electric heating wire, which can generate a steady-state radiation temperature field. The far-infrared light waves emitted by the far-infrared emission source layer directly irradiate the negative ion functional composite substrate layer, and activate the negative ion fibers through temperature field coupling and physical polarization, so as to achieve continuous, balanced and long-lasting release of negative ions.

[0038] The far-infrared emission source layer is composed of a heating emission source and a far-infrared resonant functional substrate layer, with the heating emission source located below the far-infrared resonant functional substrate layer. The heating emission source generates a basic far-infrared light wave field, which is resonantly superimposed, secondary excited, and spectrum optimized by the far-infrared resonant functional substrate layer to achieve far-infrared energy concentration amplification and deep penetration therapy.

[0039] The supporting filling layer has an upper and lower layer structure. The upper layer uses a soft, low-elasticity cushioning filler, and the lower layer uses a high-elasticity fiber material. The upper layer accounts for 1 / 6 to 1 / 4 of the volume, and the lower layer accounts for 3 / 4 to 5 / 6 of the volume. The optimal proportions are 1 / 5 and 4 / 5.

[0040] The magnetic therapy composite array layer is a rare earth magnetic group topology array, which is composed of rare earth permanent magnets and rare earth soft magnets arranged in a magnetic circuit topology. Through the complementary magnetic potential of permanent magnets and soft magnets and the convergence of magnetic lines of force, a steady-state therapeutic magnetic field with directional uniform magnetic field, magnetic energy concentration and uniform penetration is formed.

[0041] The pillow body may also include a layer of mugwort, a layer of agarwood, a layer of bamboo charcoal purification, a height adjustment buckle, a side ventilation channel, and a removable inner liner or external storage accessories.

[0042] The pillow body is either an integral structure or a detachable modular structure, and may be equipped with additional ventilation grooves, height adjustment components, a medicated filling layer, and a removable pillowcase.

[0043] Any equivalent technical substitutions that name rare earth permanent magnet arrays as biomimetic magnetic induction arrays or constant energy health-preserving magnetic modules, graphene far-infrared layers as nano-carbon light wave energy-renewing layers or far-infrared resonance layers, or biomimetic curved surfaces as spinal biomimetic arc surfaces, as long as they achieve the same technical principles of negative ion health preservation, magnetic therapy, far-infrared radiation, and cervical spine alignment and support functions, fall within the scope of protection of this patent.

[0044] Regardless of whether the magnetic flux of the magnet, the spacing between the magnetic blocks, the far-infrared emissivity, or the curvature parameters of the pillow surface are adjusted, any slight parameter tweaks that deviate from the conventional value range, while having a functional principle, structural layout, or combination logic that is substantially equivalent to this solution, constitute equivalent infringement and fall within the scope of this patent protection.

[0045] The scope of protection of this patent application is not limited to the category of sleep pillows. It also applies the same magnetic arrangement, far-infrared structure, bionic curved surface, and negative ion combination scheme to all human spinal support health care products or physiotherapy packs, such as back support cushions, lumbar support cushions, bed rest cushions, nap pillows, and seat support cushions.

[0046] This patent application uses alternative materials with the same performance to replace the rare earth permanent magnets, graphene, and negative ion fibers specified in this solution, including ordinary neodymium iron boron to replace rare earth magnets, carbon crystal or carbon fiber to replace graphene, and ordinary negative ion floss to replace special negative ion cotton. As long as equivalent magnetic therapy, far-infrared radiation, negative ion release, and spinal support effects are achieved, they all fall within the scope of protection of this patent.

[0047] The product of this patent application has one or more built-in functions such as magnetic induction, far-infrared, bionic support, and negative ions. Even if a certain function is deliberately omitted in the product promotion or text description, as long as the physical structure and function are substantially consistent with this solution, it still falls within the scope of protection of this patent.

[0048] This patent application for a rare-earth magnetic array preferably employs rare-earth permanent magnets and rare-earth soft magnets as the optimal combination, arranged according to a magnetic circuit topology configuration. The permanent magnets include, but are not limited to, rare-earth permanent magnets, neodymium iron boron permanent magnets, and other similar permanent magnet functional materials, while the soft magnets include, but are not limited to, rare-earth soft magnets, plastic flexible soft magnets, and magnetic adhesive soft magnets, and other soft magnet functional materials with similar effects. Through the mutual topological arrangement, magnetic potential complementarity, and magnetic field line convergence of the permanent and soft magnets, a stable health-promoting physiological magnetic field with directional uniformity, magnetic energy concentration, and uniform penetration is formed. This structure does not limit the specific number, arrangement, or dimensions of the permanent and soft magnets, but any similar structure that uses permanent magnets and soft magnets in a magnetic circuit topology composite arrangement to achieve orderly convergence of magnetic field lines and energy-concentrating slow-release therapeutic magnetic field falls within the protection scope of this invention.

[0049] The far-infrared emission source layer of this patent application includes a heating emission source and a far-infrared resonant functional substrate layer, with the heating emission source located below the far-infrared resonant functional substrate layer. The heating emission source preferably uses graphene as the optimal material, and also includes, but is not limited to, any one of carbon crystal, carbon fiber, or heating wire with equivalent infrared radiation efficiency. The lower graphene optimal emission source or other equivalent heating medium generates a basic far-infrared light wave field, which is then resonantly superimposed, secondarily excited, and optimized in spectrum by the upper far-infrared resonant functional substrate layer, thereby realizing far-infrared energy concentration and amplification and deep penetration therapy. Even if the order of the layers is adjusted, an irrelevant intermediate pad is added, or the layers are merged into a composite integrated layer, as long as the core principle of two-stage far-infrared excitation and amplification is used, it will fall within the scope of protection.

[0050] The negative ion health and wellness functional layer of this patent application includes a heat emission source and a negative ion functional composite substrate layer. The heat emission source preferably uses graphene as the optimal steady-state temperature field supply source, while alternative materials with equivalent heat field efficiency, such as carbon crystal, carbon fiber, and heating wire, can also be used. A constant steady-state radiation temperature field is generated by the optimal graphene emission source or other equivalent heating medium, forming a temperature field coupling intelligent energy-enabling system with the negative ion functional composite substrate layer. The steady-state temperature field polarization activates the functional fibers inside the substrate, realizing the continuous, balanced, and long-term release of negative ion health and wellness energy. This structure does not rely on the far-infrared secondary excitation conduction path. Regardless of whether the negative ion substrate is blended into the fabric, disassembled and placed in different locations, or the material name is changed, as long as the core architecture of using graphene or an equivalent heating medium to provide a steady-state temperature field and couple and activate the release of negative ions falls within the scope of protection.

[0051] This patent application divides the pillow body into seven standard independent functional areas according to the physiological curvature of the human head, neck and shoulders. Each area uses a differentiated filling matrix ratio with different modulus and density. The key support area of ​​the neck adopts a multi-level gradient layered filling structure with soft upper and hard lower parts. Even if the areas are merged, split, renamed, or the thickness is used to replace the softness and hardness of the material, as long as the seven-zone ergonomic layout and the multi-level gradient layered support logic of the neck are adopted, they will all fall within the scope of protection of this patent.

[0052] The above description is only a preferred embodiment of the present invention. Any modifications made by the inventor based on the prior patented shape, seven-zone layout, layered structure, and adjustable airbag structure, such as simplifying the number of zones, deleting some functions, fine-tuning the shape outline, replacing the negative ion intelligent substrate with a similar material, replacing the graphene excitation source with an equivalent material, slightly adjusting the upper and lower filling layer ratio within the equivalent range, making non-substantial changes to the magnetic material combination and arrangement, or only changing the appearance without substantial changes to the internal core health care structure and synergistic mechanism, shall fall within the scope of protection of the patent rights of the present invention.
