Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of wearable devices, and particularly to a wearable structure that is excited by the human body temperature and emits multi-band far-infrared rays to promote human health.
Background Art
[0002] Far-infrared rays (FIR) have various physiological benefits for the human body, and thus are widely applied to various health wearable products such as energy bands and necklaces. However, the existing technologies have many problems in structural design and material application, which hinder the performance of these products.
[0003] Please refer to the two general prior arts shown in FIGS. 1 and 2. The first is a method of mixing far-infrared powder with a silicone or rubber base material at a low ratio and then injection molding it into a bracelet or necklace. The second is a method of directly filling far-infrared powder into a hollow silicone tube. The main drawback of these designs is that since silicone / rubber is a thermal insulator, the body temperature of the wearer cannot be effectively conducted to the internal far-infrared powder, resulting in insufficient excitation of the powder and a significant decrease in the far-infrared radiation efficiency. In addition, since the silicone tube wall itself absorbs or blocks part of the emitted far-infrared rays, it becomes difficult to reach the human skin surface.
[0004] Please refer to another prior art shown in FIG. 3. It is a method of pre-processing far-infrared powder or materials such as metal germanium and titanium into far-infrared circular ingots and then fitting and fixing them into the ingot fixing holes of a metal / silicone bracelet using an adhesive. There are two problems with this structure. First, the adhesive layer forms a thermal resistance barrier between the ingot and the bracelet body, inhibiting the effective transmission of body temperature and limiting the far-infrared excitation efficiency. Second, the adhesive deteriorates over time and due to contact with sweat and chemicals, resulting in a decrease in adhesive strength, and ultimately there is a risk that the far-infrared circular ingot loosens and falls off.
[0005] Most commercially available far-infrared products concentrate their radiation wavelengths in a single, narrow range from 4 μm to 14 μm. While this wavelength range is primarily related to resonant absorption with water molecules in the human body, other wavelength ranges of far-infrared radiation may be necessary to achieve broader resonance and stimulating effects on other tissues, organs, and cells in the human body. Designing with a single wavelength range limits the breadth and depth of the overall physiological benefits.
[0006] In summary, conventional technologies generally suffer from low thermal conductivity, insufficient far-infrared excitation, detachment of functional components due to adhesive degradation, and a single emission wavelength range. Therefore, there is an urgent need for novel technological solutions that overcome these shortcomings and provide far-infrared wearable devices that are structurally stable, highly thermally efficient, and possess multi-wavelength emission capabilities. [Overview of the Initiative] [Problems that the invention aims to solve]
[0007] The main objective of this invention is to provide a multi-wave stage far-infrared wearable structure that solves the problem of reduced far-infrared excitation efficiency due to poor heat conduction in conventional technology by utilizing a highly thermally conductive metal carrier and a far-infrared functional composite layer directly filled in grooved tanks.
[0008] Another objective of this invention is to provide a structurally stable wearable device that fundamentally solves the problem of functional components falling off due to adhesive degradation in conventional technology by integrally bonding the far-infrared functional composite layer with the grooves of the metal carrier and achieving mechanical interlocking through the inverted groove structure.
[0009] Furthermore, the objective of this invention is to provide a wearable structure that emits multi-wavestage, multi-peak far-infrared radiation, which can extend the radiation wavelength range from 2 μm to 100 μm by mixing far-infrared materials having at least two different radiation spectral characteristics, thereby providing a broader and deeper physiological regulatory effect on the human body. [Means for solving the problem]
[0010] To achieve the above objective, the present invention provides a multi-wave stage far-infrared wearable structure. The structure includes a metal carrier which is a wearable accessory body with high thermal conductivity, and the metal carrier is provided with grooves extending along its length or along a specific region, and further includes a far-infrared functional composite layer integrally solidified and bonded within the grooves. The functional composite layer is composed of multi-wave stage far-infrared powder and a curing agent substrate, and is characterized in that the functional composite layer is in direct contact with the inner wall surface of the grooves to form a gapless heat conduction path. The cross-sectional contour of the grooves has at least one inverted slope structure, and the opening width of the grooves is designed to be smaller than the bottom width, thereby creating a mechanical interlock effect with the far-infrared functional composite layer. [Effects of the Invention]
[0011] Compared to conventional technology, the beneficial effects of this invention are as follows:
[0012] (1) Extremely high thermal conductivity: By directly conducting body heat to the closely adhering far-infrared functional composite layer using a highly thermally conductive metal support, and eliminating all thermal resistance barriers, the far-infrared powder is excited rapidly and stably, achieving a radiation efficiency far higher than conventional technologies using silicone substrates or adhesive fixation.
[0013] (2) Outstanding structural stability: The functional composite layer and the metal carrier are integrally bonded within the grooved tank. In particular, when the grooved tank has an inverted groove structure, the bonding force is based on mechanical interlocking, thus fundamentally eliminating problems of detachment due to aging deterioration or environmental factors.
[0014] (3) Physiological benefits of broad spectrum: By mixing different types of far-infrared materials, broad-spectrum far-infrared radiation with multiple emission peak values (at least two peak values within the range of 2 μm to 100 μm) is generated, which corresponds to the resonance frequencies of different tissues and cells in the human body, resulting in a more comprehensive health-promoting effect.
[0015] (4) High-density far-infrared radiation: This invention allows for a filling rate of far-infrared powder up to 70 wt%, significantly improving the effective material density per unit area and enabling the emission of a higher far-infrared energy flux. [Brief explanation of the drawing]

Embodiments for Carrying out the Invention
[0018] Hereinafter, with reference to the drawings, preferred embodiments of the present invention will be described in detail. The following embodiments are merely illustrative explanations and do not limit the scope of the utility model registration claims of the present invention.
[0019] Please refer to FIGS. 4 and 5. A multi-band far-infrared injection type wearable structure 4000 according to the first embodiment of the present invention is shown. The structure mainly includes a metal carrier 100 and a far-infrared functional composite layer 200a.
[0020] The metal carrier 100 is made of a metal material having excellent biocompatibility and high thermal conductivity such as pure titanium, titanium alloy, 316L stainless steel, pure silver or K gold, and its thermal conductivity is greater than 15 W / (m·K). It can take any shape that can be worn on the human body, such as a bracelet, necklace, ring, anklet, etc. One or more grooves 100a extending along its annular path are provided on the outer surface or inner surface of the metal carrier 100.
[0021] As shown in the cross-section of FIG. 5, the cross-section of the groove 100a is designed with a special contour (such as trapezoidal or swallowtail shape) having at least one barb structure 100b, and the groove opening width W1 is smaller than the groove bottom width W2. Due to this "narrow mouth and wide bottom" design, the internally filled and cured far-infrared functional composite layer 200a forms a mechanical interlock structure in which the movement in the opening direction is physically restricted, effectively preventing the composite layer from falling off or peeling under extreme external forces or temperature changes.
[0022] The far-infrared functional composite layer 200a has a layer structure in which the multi-band far-infrared powder and the curing agent matrix are solidified integrally. The composite layer has a dense structure substantially free of air bubbles, and by closely adhering to the bottom surface and side walls of the groove without gaps, it constitutes a direct heat conduction path from the metal carrier 100 to the far-infrared powder. The outer surface of the composite layer is flush with the outer surface of the metal carrier or is set at a position 0.1 mm to 2 mm lower. The weight percentage of the multi-band far-infrared powder ranges from 20 wt% to 70 wt% of the entire composite layer, and the particle size is controlled between 0.01 μm and 100 μm, thereby forming a dense dispersion structure.
[0023] As shown in FIG. 6, the multi-band far-infrared powder of the present invention is a mixture of materials (short-wave band powder 500b and long-wave band powder 500a) having at least two different radiation spectrum characteristics, and has a structural characteristic of emitting far-infrared rays having at least two energy peak values in the wavelength range of 2 μm to 100 μm at body temperature (30 degrees Celsius to 40 degrees Celsius).
[0024] Please refer to Figure 7, which shows a multi-wave stage far-infrared filled wearable structure 5000 of the second embodiment of the present invention. The main difference from the first embodiment lies in the internal structure of the far-infrared functional composite layer. This structure has a two-layer structure including a multi-wave stage far-infrared powder layer 300 deposited and filled in a grooved tank 100a, and a sealing hardening agent layer 300a that covers the upper surface of the powder layer and is tightly bonded to the side wall of the grooved tank. The thickness of the sealing hardening agent layer 300a is between 0.1 mm and 2 mm, and it serves to prevent leakage of the powder layer and protect it from the external environment. With this structure, the far-infrared powder density in the grooved tank approaches the filling density, achieving a higher far-infrared radiation flux compared to the first embodiment.
[0025] The inner wall surface of the grooved tank of the metal carrier may have a surface-modified structure achieved by roughening treatment (such as sandblasting) or plasma activation treatment, thereby increasing the contact area with the far-infrared functional composite layer and further strengthening the mechanical bonding force. In addition, the outer surface of the metal carrier may have a surface finish layer selected from polishing, anodizing, or PVD coating, improving appearance quality, corrosion resistance, and hardness.
[0026] Those skilled in the art will see that the present invention is not limited to the details of the exemplary embodiments described above, and can be realized in other specific forms without departing from the spirit or basic features of the present invention.
