Description

Far infrared radiation film for heat application

The invention relates to a far infrared heat radiation sheet, in particular to a hot film formed by a micro-arc oxidation treatment, a dip-coated sol process metal sheet and an electric heating film.

The prior art involved in the far-infrared low-temperature and high-radiation efficiency and its health-care use of the far-infrared heat radiation film of the present invention is described in two parts: one is the application of far-infrared (line) technology and related technologies. The second is to search for comparisons of prior patents.

At present, the application of far-infrared technology: In the past 20 years, the US Aerospace Science's Tera Hertz (THz) technology is within the scope of far-infrared technology, and its application of "no damage detection" and "microscopic imaging" is more It involves more and more extensive scientific applications of new materials such as national defense, biotechnology, refined agriculture, and the global environment.

In recent years, domestic TV media has reported on the magical efficacy of far-infrared health care products and their exaggerated claims. In particular, there are manufacturers and materials experts who claim that their health care products "use special materials to have special radiation." ~14 micron far-infrared health care products..." advertised that such far-infrared products "mislead" the public.

In fact, it is obviously inconsistent with the common sense of science that we know!

Popular knowledge: According to the modern infrared physics theory, objects above absolute temperature (-273 °C) can "radiate" or "absorb" far infrared rays.

That is to say, all the substances that we have seen so far, including humans, animals and plants, clothes, fruits, stones on the road, cow dung, etc., all have "far infrared rays", that is, they can all be " Radiation "far infrared rays can also "absorb" far infrared rays. And the wavelengths of far infrared rays radiated by almost all of these substances also fall. Enter the range of 8~14 microns! It is not only the special materials of its manufacturer's experts that have "far infrared rays"! However, the "energy" of far-infrared rays radiated by these substances is different. For the human body, some far-infrared rays "energy" are "huge" to "burn" people; some far-infrared rays "energy" "Small" is almost equal to "Nothing"!

At present, China's Ministry of Health and Welfare regulations on medical equipment permits: the total power of medical grade far-infrared appliances should not exceed 500W, and must be operated by "with qualified medical technicians". Obviously, its high power has a certain degree of danger!

In addition, the low-power far-infrared appliances of the Ministry of Health and Welfare's "first-class licensing method" for medical equipment are "non-invasive" to the human body, and the qualified manufacturers are required to be certified. Most of the people use it for health care, rehabilitation, etc., and it has not been confirmed by international information that it has a recognized "medical" effect.

Therefore, regarding the magical efficacy of far-infrared health care products, it can cure all kinds of false reports and cure cancer, and it is obviously misleading the general consumers.

Popular knowledge 2: According to Wien's displacement law, the hotter an object, the shorter the wavelength of its radiation, or the higher the frequency of its radiation, the higher the relative radiation energy.

According to the mathematical expression of Wien's displacement law: λ = b / T where λ is the peak wavelength of the radiation (in meters), T is the absolute temperature of the black body (unit K), where b is the proportional constant, called Wien displacement The simple simple memory is " 2897 ". The wavelength λ of the radiation (absorption) of the human body (37 degrees C) is approximately equal to 9.3 μm (micrometers). Although the above-mentioned and far-infrared radiation bands of 8 to 14 micrometers can provide (including) 9.3 micrometers that the human body must match, it does not mean that it has "far infrared rays that have substantial benefits to the human body." Among them, there are reports that the far-infrared radiance (including the 9.3 μm range) averages below 0.8, and at room temperature, there is almost no "resonance" thermal effect on the human body, which means that there is no substantial benefit to the human body.

Therefore, since the radiant energy of the far-infrared product is related to the temperature, it is necessary to indicate the relative "temperature" and "emissivity" parameters to give a description.

Some far-infrared textile garments claim to be "far infrared" in a "room temperature" environment. Has "healing" effect! Obviously, it does not meet the principle of heat transfer related to thermodynamics!

Assume that the "normal temperature" environment is 25 degrees C, so the far-infrared textile clothing should be at about 25 degrees C. However, the body surface temperature is about 32 degrees C. The phenomenon of thermodynamics "heat transfer to low temperature" should be It is the "high temperature" of the human body that transfers "thermal energy" to this "low temperature far-infrared textile clothing" rather than "low temperature far-infrared textile clothing" to transfer heat energy to the human body surface, isn't it?

Unless this is a source of heat added to the "low temperature" far-infrared textile garments, it is more likely that the far-infrared textile garments become at a higher temperature than the surface temperature of the human body, such as 40 degrees C.

Here, "more likely" is not "certain"! how to say?

A heat source added to the far-infrared textile garment is, for example, an impedance type electric heat source, and the "heat" emitted by the far-infrared textile garment is close to the skin and is directly transmitted to the human body surface by using the human body surface as a medium. Internal organization, this kind of transmission by medium is called "conduction".

However, the added heat source is close to the skin conduction heat. Obviously, the "hot" heat temperature should not be greater than 50 degrees C, otherwise the body surface is easily burned!

However, when the temperature is at 50 ° C, the "heat" emitted by the heat source is absorbed by the inner layer of the textile garment by about 45%, and then reflected by the body surface by about 50%, and the remaining penetrates the body surface into the tissue. The "hot" is less than 5%.

Moreover, less than 5% of the "heat" generated by this heat source is actually a "near-infrared" with a slightly visible red light, which is not the "far infrared" range required by the human body. According to Steven Bozeman's law of radiation and Wien's law of displacement, 5% of the total radiant energy of far-infrared textile clothing! Very "very small", it can be inferred that its far-infrared heat radiation effect on the human body is almost equal to "0"!

In fact, if the "peak" of this 5% heat radiation can extend beyond 9.3 microns and has a sufficiently high (eg, above 0.8) emissivity, it is slightly more likely. Here, "something is possible", too, is not "certain" possible!

The material of the 5% thermal radiation heat source must also have a high (at least 0.8 or more) radiance to create a "resonance effect" in the body surface of the human body! Actually, Because of the temperature, far-infrared products emit radiant energy through the heat generated by temperature. The amount of energy released is determined by the surface temperature and the surface properties (the object is expressed in terms of emissivity). The emissivity is: the ratio of the radiant energy of this object to the radiant energy of the black body at the same temperature. The radiant energy of the black body is represented by 1, and the emissivity of other objects is between 0 and 1. The higher the emissivity, the The same amount of energy radiated from this wavelength.

Therefore, since the amount of energy released by the far-infrared product is determined by the surface temperature and the radiance of the surface of the object, only a high emissivity can be taken under consideration of the temperature "not scalding the human body" (0.8 The design of the above direction has practical significance in the use of human medical care (hot compress or hyperthermia)!

According to the Kirchhoff Laws energy conservation calculation, the energy radiated by far infrared rays is equal to the energy absorbed by the human body. Obviously, if the energy radiated is "weak", the energy absorbed by the human body must be "weak". This "weak" energy produces almost no "resonance effect" of far-infrared to human tissue.

Popular knowledge 3: According to electromagnetic wave theory and electromagnetic wave spectrum, the far-infrared range from 4 to 1000 micrometers has a small section of 8 to 14 micrometers. It is a region of fertility that is extremely important for the growth of humans and all living things. . In fact, according to Planck law, the "thermal radiation" of objects on the ground is mainly concentrated in this interval. This 8~14 micron range is also called "far infrared" in the far infrared product industry. Because this "far infrared" is "invisible" by human eyes, this specification calls this "far infrared" as "far infrared". , ignoring the word "line".

Moreover, if "far infrared rays" are "invisible" by human eyes, then the "red color light" radiated by commercially available therapeutic devices or health care products is obviously not all "far infrared" and should be included. "Near Infrared" and "Red Light".

When the far-infrared heat radiation is radiated onto the skin of the human body, part of it is "reflected" on the surface of the skin. For example, Caucasian skin reflects about 60% of its energy; while black human skin reflects about 30% of its energy.

Also, because our skin has many uneven surfaces (not easily seen by the human eye), the far-infrared heat radiation is also partially "scattered" on the uneven surface of the skin, and different types of surface tissue have different Scattering properties. So, under the same conditions, According to foreign related health literature data: the energy of the far-infrared radiation source with low emissivity (below 0.8) can enter the skin tissue layer is limited! In general, far infrared radiation penetrates the skin to a depth of only about 0.5 to 2 mm (mm) and thus acts only on the superficial tissue of the skin.

Also, according to the Steven-Bozemann radiation law: W=sT ⁴ , the strongest radiation intensity W of the human body can be calculated, which is related to the history-wave constant S (5.67*10 ^-12 w/cm ² K ⁴ ) and the absolute temperature T. relationship. The strongest amount of radiation in the human body is equal to 0.046 W (46 mW milliwatts) per square centimeter of radiant energy. If the average human face is 200 square centimeters, the total facial radiation power of the human face should be 9.2 watts. These energies include electromagnetic waves of various wavelengths, but most of the range falls within the invisible infrared range.

Therefore, if the radiant energy per square centimeter is 0.046 W, it is obviously inefficient.

According to Steven Bozeman's law of radiation, objects with temperature radiate energy W in almost every electromagnetic wave band. The peak value of each curve also changes due to the temperature T. The higher the temperature, the greater the radiant energy. Therefore, it is only meaningful that the radiance of all far-infrared products is at least "measured at which temperature." The patents mentioned above or their commercial products are often only marked with an emissivity of 0.9 or more. Whether the "intentional" or "uninformed" is ignored by the temperature indicating the measurement, causing the misleading of the "fishing beads" .

In the infrared range: generally widely distinguishes near-infrared (NIR), which is mainly used in communications, laser, infrared photography, etc.; mid-infrared (MIR); and far-infrared (IR) from 8 μm to 14 μm ), is thermal imaging The operating range of the system is widely used in medical, industrial and military fields.

However, in the case of the human body, the skin temperature of the face, hands, and the like is about 32 ° C at room temperature of about 20 ° C. The infrared radiation rate ( ε ) of human skin is very high, and the average value above 4 μm (micrometer) is about 0.99, which is close to the black body. However, most of the radiance is distributed in the far infrared (8 μm to 14 μm of FIR), and only a few are distributed in the mid-infrared (MIR 3 μm to 5 μm ). Therefore, the "high emissivity" far-infrared products can produce the practical needs of "radiation" and "absorption" in the medical and health care applications of the human body!

Related prior art applications: Among them, related art (A) Micro-Arc Oxidation (MAO), micro-arc oxidation treatment is a new technology developed in the 1980s, which is an improved technology derived from anodized processing. Also known as Plasma Electrolytic Oxidation (PEO), microarc oxidation has been used in recent years for the surface modification of light metals. This method combines plasma chemistry, thermochemistry, and electrochemistry to form a thin layer of aluminum oxide on the surface of a valve metal or its alloy, such as a 1000 or 6000 series aluminum alloy. The layer is not uniform. In some weak areas, it will be broken by a high voltage of several hundred volts. The temperature in this area of the breakdown suddenly increases, forming an instantaneous high temperature and high pressure plasma area, melting the substrate. The electrolyte is vaporized, and the molten aluminum metal combines with oxygen radicals generated in the water to form α- Al ₂ O ₃ and γ-Al ₂ O _{3 having} relatively high hardness. The micro-arc oxidation electrolyte generally uses an alkaline salt solution (such as citrate, phosphate, borate, hypophosphite, etc.), so the environmental impact is small.

The biggest advantage of the micro-arc oxidation method is that the ceramic film formed on the surface of the treated metal (the thickness of which can be 30~200μm) can be used to make the micro-arc oxide film even if the ceramic material is not introduced from outside. It is α-Al ₂ O ₃ ) with high performance of ceramic membrane, its chemical properties are very stable, it can protect the internal substrate and has a very good bond with the substrate, and has wear resistance, corrosion resistance and good Insulation performance, insulation resistance up to 100MΩ.

At present, the methods of micro-arc oxidation, the world's advanced countries such as the United States, Japan, Britain, Germany, the Soviet Union and mainland China and other research units have been constantly innovative and mature new technologies, such as: China Patent Publication No. CN 1772968 A, The name is a method of micro-arc oxidation on the surface of a magnesium alloy.

Conclusion of related micro-arc oxidation: Please refer to the previous technology, in which a micro-arc oxidation treatment method combines plasma chemistry, thermo-chemistry and electrochemistry, and the whole process is to continuously find the aluminum oxide layer. Defective or fragile breakdown, causing aluminum and oxygen to diffuse and react with each other and then generate a new aluminum oxide film. In short, the preparation method has different parameters (such as time, film thickness, material and electrolyte). Many cumbersome processes.

According to the data, from the international application market and its patented technology products in the past five years, the use of micro-arc oxidation technology is mainly applied to the "heat dissipation" of electronic products, such as the heat dissipation effect of LED lights and smart phones, others. It is also used in industrial machinery for wear resistance and corrosion resistance. However, it has not been found in the application of heat application to "far infrared" and the health care industry.

Among them, related art (B) Sol-Gel treatment technology, sol gel is a colloidal suspension, and the porous gel produced by the method can be purified by chemical method and high temperature fire to obtain high purity. Oxide. It is a method of preparing nano-scale organic-inorganic hybrid materials. It forms a stable transparent colloid in solution and can be easily covered on a substrate having a large surface area, and can be directly coated on the surface of the substrate to form a nano-sized structural film.

A colloid is a dispersion system with a small dispersed phase particle size. The gravity of the dispersed phase particles is negligible, and the interaction between the particles is mainly a short-range force. Sol (Sol) is a colloidal system with "liquid" characteristics; gel (Gel) is a colloidal system with "solid" characteristics.

The materials derived from the sol-gel method have many applications in various fields. The most important application of the sol-gel method is to produce a film on the surface of a substrate by a spin coating method, a dip coating method, a spray method, an electrophoresis method, an inkjet method, a roll coating method, or the like on a film. Optical coating, protective coating, decorative coating, and electro-optic materials can be produced not only on glass, metal, but also on various other substrates.

During the test of the embodiment of the present invention, one of the sol-gel method (Dipping) was prepared by a conventional process, and a part of the defect rate was found after the "evaporation" process was carried out. It occurs on the surface of the sol film layer and is easily peeled off and scratched.

After many experiments have known this phenomenon, another method of far-infrared drying (such as the conveyor track machine 45 of Fig. 4) has been designed to replace the original volatilization process steps, which has indeed solved this problem. The radiant solution of the "far-infrared heat radiation film" of the present invention is improved by the sol liquid whose main component is cerium oxide.

For the convenience of understanding, since the embodiment of the present invention adopts a dip coating method for the sol-gel treatment process, and an improvement of far-infrared drying in the dip coating method, the related art (B) sol-gel ( In the aspect of the Sol-Gel processing technique, the embodiment of the present invention is simply referred to as a "dip coating sol (film) process", which will be described in further detail in the following embodiments.

The related art (C) is a resistive electric heating film, which refers to a thin soft material which has an electrical resistance to be connected to a power source and can generate heat. For example, Polyimide Film (PI) ultra-thin electric heating sheet, silicone electric heating sheet (line) Silicon Rubber. There is also a Polyimide Film (PI) Silicon Rubber electric heating sheet which is combined with silicone rubber and PI. In addition to maintaining the structural strength and flexibility of the silicone electric heating sheet, it also has excellent heat conduction efficiency of the PI electric heating sheet, and most of them are produced by etching. In addition, there is a transparent ultra-thin electric element Polyester Film (PET) electric heating sheet, which also has the characteristics of PI electric heating sheet, can withstand temperature to 130 ° C, waterproof and moisture resistant, often used in health care, beauty, heat preservation, beauty power generation rod, Fog, drying and other livelihood supplies. Thirdly, there is also a printed electric heating sheet which is made of a printed electric resistance material and is used for defogging of a rear view mirror of an automobile. There is also an aluminum foil electric heating sheet, which is applied to the heating of the toilet seat cushion, the defogging of the bathroom mirror, the low-temperature cultivation of the biochemical vaccine, the seedling, the heat preservation breeding, and the etching production will not cause the uneven distribution of heat caused by the block damage. In addition, there is a special material printing type electric heating material, which can directly print electrothermal materials on non-woven fabric or rubber, and is used as electric heating and warming articles, and is suitable for beauty jacket, warm gloves, warm vest, warm clothing and the like.

Some embodiments of the present invention adopt a conventional and well-established Polyimide Film (PI) ultra-thin electric heating sheet, and design a 5 ohm ohmic resistance value, 8 cm * 16 cm size electric heating piece, commissioned by the manufacturer. Usually, most electric heating films are flat and thin, and they can be heated on both sides. In this embodiment, a temperature control unit is attached to the (PI) ultra-thin electric heating sheet to provide safe use for low-temperature heating, and a soft wrapping soft cover is used for reflecting and hindering the "unusable" heating of one side to increase efficiency.

The related technology (D) further combines the above (A), (B), and (C) to produce a technical feature with low temperature and high emissivity, safe and easy to use, and its unpredictable effect, as described later. Description of the examples.

As disclosed in the prior art, it is apparent that the combination of the related art (D) and its effect are not And the prior art and the related patent documents below do not disclose the solution to the common problems caused by the far-infrared heat application of the human body.

As shown in FIG. 5, it is a schematic structural view of the cast aluminum alloy 400 with surface modification of the embodiment 5 after dyeing treatment and sealing treatment. Due to the diffusion of the titanium dioxide particles, the pores 411 of the oxide layer 41 formed on the surface of the cast aluminum alloy substrate 40 are small, and in this embodiment 5, a dyed layer is formed on the surface of the oxide layer 41 by an electrostatic spraying method. After 42, the sealing treatment was carried out by means of sol-gel sealing, and it was washed with flowing water for 1 minute and left to stand at room temperature to complete the sealing structure 412 of the oxide layer 41.

Comment: I456091 has a surface-modified cast aluminum alloy... dyed layer 42, and then sealed by sol-gel sealing. The technique is based on the use of a sol-gel method as a sealing application for protecting the dyed layer 42 on the cast aluminum alloy oxide layer.

The Republic of China patent M336666 integrated heat-dissipating substrate comprises a metal substrate, a metal compound insulating layer, a sealing material and a metal film, wherein the metal compound insulating layer is formed on the surface of the metal substrate and has a plurality of holes, and the sealing material is filled In the hole of the metal compound insulating layer, the hole is narrowed, or the density of the hole is changed, or the hole is completely sealed, and the metal film is formed on the insulating layer of the metal compound by vacuum coating or printing process, and then used.

Comment: Integrated heat sink substrate filled with a seal in the hole of the metal compound insulation The material is 23 water, a sol gel or a mouthpiece. Obviously, the use of sol gel as a process for heat dissipation is a process.

The Republic of China Patent No. M491773 "flashlight with far infrared ray" includes: a body having a holding portion and a light source portion connecting the holding portion, the outer periphery of the body having a far infrared ray coating, the far infrared ray The coating radiates far infrared rays by the heat sink of the light source portion being absorbed by the grip portion. The above far infrared ray coating (14) is produced by the following steps: Step A. A solution of an inorganic metal salt such as a chloride salt, a sulfate or a nitrate or an alkoxy compound such as tetraethoxy decane is used as the first material. Step B. Mixing the first material with water, an acidic solution such as ammonium hydroxide, hydrochloric acid, acetic acid or nitric acid, adjusting the pH to less than 3, and forming a gel by a "sol gel method". Alternatively, the first material is mixed with water, an alkaline solution such as sodium hydroxide, and the pH is adjusted to be between 8 and 10, and then gelled by a "sol gel method". After the obtained gel is applied to the body (1), the body (1) is calcined, wherein the calcination temperature is between 500 and 900 ° C, so that the gel forms minute crystal grains, which are formed after being cooled. The far infrared coating (14). The light source portion (12) can be transferred to the far infrared ray coating (14) by the working heat generated by the illuminating unit (122). After receiving the working heat energy, the far-infrared coating (14) radiates far-infrared rays, so that the far-infrared rays act on the palm (A) or the wrist of the user, which can promote microvascular expansion.

Comment: According to the LED lamp described in the manual of M491773 and the second figure, it is actually "hard" to produce a palm (A) or wrist that causes far infrared rays to act on the user, which can promote microvascular expansion. The feasibility, such as the following question points:

Question 1: It radiates far infrared rays "How can it penetrate" the lampshade in front of its flashlight? In practice, the "far infrared energy" generated by the "light cover" transparent through its "flashlight" is almost "zero"! All of them are the "visible light" range emitted by LED lights! Unless you remove the "shade", if there is a "shade" in front of the flashlight.

Question 2: Even if the "shade" is removed, as shown in the direction of the far-infrared coating (14) shown in Fig. 2, it can be seen that the far-infrared coating (14) radiates its "far infrared" in its In the light source section (12), there is a "large part" in the direction of "interference". It is not like the LED light can be directly emitted in front of its flashlight. The line has the property of "straight forward", reflection, transmission, and the like. Therefore, the energy radiated by the far-infrared coating (14), due to the error in its radiation direction, has already been "very weak" energy, and again caused a second loss, leaving little!

Question 3: As shown in the description of an LED lamp and the second figure, the "far infrared coating (14)" receives a "heat" from its LED lamp to emit "visible light". The natural "thermal convection" method inside the source part (12) is transmitted, and the "heat" transmitted to its far-infrared coating (14) is very limited, that is, its far-infrared coating (14) accepts it "very Can the temperature of the far-infrared coating (14) be increased after the limited working heat? According to the common knowledge of advanced science, the radiance and radiant energy of the far-infrared coating (14) is no different from the far-infrared coating (14) in the normal temperature state, that is, its far-infrared coating ( 14)" As with other substances, it can radiate far infrared rays! In this way, the "far infrared coating (14)" and "one LED light" are not related to "necessity".

Question 4: As shown in the specification of M491773, an LED lamp and the second picture, the far infrared generated, because the first light can not penetrate the front of the flashlight "to the user's palm (A) or Wrist"; second, its radiation direction is not correct; third, its radiation energy is insufficient, etc., it can be known that the design and principle of its structure are not specified.

Therefore, the micro-arc oxidation and sol-gel methods similar to those disclosed in the above "patent" differ in the results of metal treatment (such as dyeing or heat dissipation), or are contrary to scientific principles or lack of specific description of "far infrared."

Retrieving the comparison of "far-infrared" patents related to the prior art: Far-infrared patent information retrieval data revealed that most of the patent specifications only refer to the words "far infrared" and do not specify the "far-infrared" technical content. For example, at what temperature does the radiance have? What is the amount of radiation? Radiation direction and so on.

According to the Republic of China Patent Information Retrieval System, a total of 86 patents and other related patent materials in Japan, the United States and the mainland were identified by the "Far Infrared AND Healthcare" combination as follows: Announcement on April 1, 2014 The Republic of China new patent M475264 "The far-infrared ray illuminator with adjustable illumination area", the description of which is mainly based on a main illumination device Each of the two sides is respectively connected with a pair of illumination devices; wherein the main illumination device is respectively formed with a first pivoting portion on opposite sides of the left and right sides, and the second pair of illumination devices respectively form a second pivoting portion on one side, and The first pivoting portions on both sides of the main illuminating device are respectively coaxially pivoted with the second pivoting portion of the sub illuminating device, so that the two illuminating devices are pivotally connected with the main illuminating device to form a multi-section illumination. Therefore, the present invention mainly provides a user to irradiate a part (such as an arm) through a pivoting sub-irradiation device to provide different illumination directions, so that the illumination area can have greater adjustment elasticity to enhance the improvement of local blood circulation.

In the specification of the M475264 patent, only "the plurality of ceramic sheets 13A are fixed in the second cover 121, ... when the ceramic sheets 13A generate heat, the far infrared rays are generated". In particular, the far-infrared power density outside the range of the illumination indication area 80A is only 0.6 mW per square centimeter, which is far from the power density capable of functioning, and thus can be regarded as invalid, and the closer the illumination indication area 80A is within The far-infrared power density of each of the projection areas 131, 131A is higher, for example, in the projection area 131A corresponding to the ceramic sheet 13A of the sub-irradiation device 12, the far-infrared power density is 10 mW per square centimeter; the ceramic in the main illumination device 11 The projection area 131 corresponding to the sheet 13 has a far-infrared power density of 20 mW per square centimeter.

Comments: (1) In its M475264 patent specification, its characteristic technology is that its structural design of the irradiation area of the far-infrared illuminator is independent of the far-infrared technical features. Further, (2) in the patent specification, only "the plurality of ceramic sheets 13A are fixed in the second cover 121, ... when the ceramic sheets 13A generate heat, the far-infrared rays are generated", and it is not described that the ceramic sheets 13A are produced. What kind of far infrared? Furthermore, (3) the patent specification describes "the range of the illumination indication area 80A...", obviously, the characteristic technique is to explain: "The structural design of the adjustable illumination area can adjust the heating of the ceramic piece 13A to be different. The size of the far-infrared power density, which is the "structural design" of thermodynamics "the thermal energy of radiation is inversely proportional to the radiation distance", has nothing to do with the characteristics of far-infrared technology.

Comment: Assume that it produces a vector area a of "magnetic energy". If there is no current I , then the magnetic dipole moment of the "magnet" reacts to the human body is almost 0 (U = Ia ), and its ore is Far infrared rays "at normal temperature" do not explain how to improve blood circulation.

The above related technologies (A) micro-arc oxidation method, related technology (B) Sol-gel (Sol Gel) processing technology and related technology (C) electric heating film, etc., of which "combination" or "formation" of the three According to the contents and illustrations of the patent specifications described by them, and the products displayed at the 2014 International Medical Equipment Exhibition, none of them have appeared.

As an embodiment of the present invention, it specifically clarifies and proposes a low-temperature, high-radiation, far-infrared heat-radiating soft (thin) sheet suitable for personal and home health applications, and is used to separate larger far-infrared medical instruments from hospital clinics.

The far-infrared heat radiation film of the embodiment of the invention has the characteristics of high-infrared rays in the range of 6 to 14 micrometers in the low temperature range (40 to 50 degrees C). The emissivity ε (having an average value between 0.9 and 0.99) and its radiant power average 40 to 60 mW/cm ² .

The far-infrared heat radiation film of the embodiment of the present invention clearly indicates that the radiation direction of the far-infrared heat radiation film is "direct" to "contact" the corresponding part of the human body surface, and importantly, the human body This part of the table corresponding to "contact" must be "naked".

"Direct" means that there is no other medium other than air between the far-infrared heat radiation film and the human body surface, because according to the data of Far Infrared Complementary Medicine in Japan and Europe, the human body is displayed on the human body. The radiant power of the body surface is preferably between 40 and 60 mW/cm ² , but the energy of the radiant power in this range “can hardly penetrate” a thin piece of paper or cloth, so there is no medium such as clothing; the “contact” means There is a small distance between the far-infrared heat radiation film and the human body surface (because the heat radiation does not need to be transferred by the intermediate medium) or the two are in direct contact with each other (the low temperature does not instantly burn the human body surface).

FIG. 1 is a schematic side view of a far-infrared heat radiation film according to an embodiment of the present invention; FIG. 1 is a schematic view showing the appearance of a radiating metal foil according to an embodiment of the present invention; Please refer to FIG. 1C for a schematic view of the appearance of a wrapped soft cover according to an embodiment of the present invention.

As shown in FIG. 1 , a far infrared heat radiation soft (thin) sheet 100 according to an embodiment of the present invention includes at least: a radiation metal sheet 10 as shown in FIG. 1A, an electric heating film 30 as in FIG. 1B, and A wrapper 40 as in Figure 1C. Among them, the appearance drawings shown in FIG. 1A, FIG. 1B, and FIG. 1C can help to further understand FIG.

Wherein, as shown in FIG. 1, the lower surface 102 of the two sides of the radiating foil 10 is adhered to one of the two faces of the electric heating film 30 by a temperature-resistant adhesive 20, so that the electric heating film 30 is energized. The heat of resistance is conducted from the upper surface 301 via the temperature-resistant adhesive 20 to the lower surface 102 of the radiation foil 10, and then the "heat of resistance" is converted into "radiation heat" by the radiation foil 10, and then irradiated. An upper face 101 of the foil 10 is radiated out to form a radiation phenomenon of the far infrared radiation film 100.

The lower surface 302 of the electric heating film 30 is connected to the closing surface 42 of the bottom of the soft cover 40. From the appearance of the far infrared radiation film 100, the electric heating film 30 is hidden by the wrapped soft cover 40 (surrounding live).

A power input port 32 and a temperature control unit 31 are disposed on an upper surface 301 of the electric heating film 30. The power input port 32, the circuit of the temperature control unit 31, and the printed resistor wire 33 on the electric heating film 30 are disposed. The loops and the like are all "series" together, so that the power input 埠32 is input to the power source, and when the heat is generated by the resistor wire 33 on the electric heating film 30, the temperature of the heat generation can be controlled by the temperature control unit 31. For example, when the electric heating film 30 of the embodiment inputs a DC5V voltage of 1A ampere, the temperature control unit 31 (temperature control range 45 degrees C error 3 degrees C) detects that the temperature on the electric heating film 30 is lower than the lower limit of 45 degrees C (45- 3=42) can be connected to the power supply and; when the temperature on the heating film 30 is higher than 45 ° C upper limit (45+3=48), the power can be disconnected from the power supply.

Then, how does the radiation foil 10 convert "resistance heat" into "heat radiation"?

The details will be as described in the following embodiments. Here, only the following experiment of the radiant metal foil 10 and the test data report made by the commissioned industrial research institute in May 2014: an example of the radiant metal foil 10 of the embodiment of the present invention, wherein The spare "metal" is a 1050 aluminum sheet with a thickness of 0.1 mm and three sheets of ABC, wherein the A sheet sample is not treated, and the B sheet sample is subjected to a micro-arc oxidation (MAO, Micro-Arc Oxidation) treatment, and the C sheet sample. It is first treated by micro-arc oxidation and then treated by a dip-coated sol.

The above three samples of ABC were tested in the laboratory by Thermal Video: (1) at room temperature of 20 ° C and wavelength of 4 to 14 μm, the emissivity: 0.05 for the A piece. The B piece sample was 0.85 and the C piece sample was 0.98. The embodiment of the present invention is formed in a C-plate sample mode, and is subjected to a micro-arc oxidation treatment and then subjected to a sol-gel treatment to form a radiation metal foil having a high emissivity. The test results report that the radiation foil can have an emissivity of up to about 0.98 at 40 °C.

To this end, the embodiment of the present invention uses a resistive electrothermal film 30 to generate an average temperature of about 45 degrees C (40 to 50 degrees C) under the control of the temperature control unit 31 for simulation experiments. Experimental temperature at the time.

The temperature control unit 31 used in the embodiment of the present invention is a LM26CIM5X temperature switch manufactured by Texas Instruments, which has a switching temperature of 45 degrees C and an accuracy of plus or minus 3 degrees C.

The electric heating film 30, in order to adopt a relatively convenient, relatively safe, relatively bendable heat source, the embodiment of the invention adopts a PI electric heating film, the resistance value of which is designed to be about 5 Ω ohm, and the power source for supplying heat to the heat source is DC 5V and 1A~2A current, which can be easily obtained from the "rechargeable battery pack" of the universal mobile phone in the existing market.

As shown in Fig. 1, the electric heating film 30 is supplied from the external power source 321, and is supplied with a voltage of DC 5V and a current of 1 A, and is formed on the upper surface 301 and the lower surface 302 of the electric heating film 30 by an impedance of 5 ohms. 5W "resistance heat", this "resistance heat" continues to be energized, and its temperature continues to rise.

This "heat of resistance" of about 5 W is about 0.036 W/cm ² (5/8*16) on a C-piece sample of 8 cm * 16 cm.

The electric heating film 30 of the embodiment of the present invention has a size area of 8 cm*16 cm. In winter or in cold climates, external power supply 321 (such as mobile phone rechargeable battery) can be switched from 1A current output to 2A current output to improve power heating.

As shown in Fig. 1, the temperature of the electric heating film 30 continues to rise, and if it is close to or exceeds about 50 degrees C, it may cause burns on human skin! Therefore, a temperature control unit 31 connected in series with the power input terminal 32 causes the temperature control unit 31 to sense the temperature of the electric heating film 30 and is limited to between 42 and 48 degrees C.

In the embodiment of the present invention, after a resistive electric heating film 30 and a radiation metal foil 10 are adhered by an adhesive, the two are assembled by a symmetric wrapping soft cover 40 to form a bendable shape. Soft suit combination. The outer surface is formed as shown in Fig. 1 : one side of the outer surface is an open surface 41 of the soft cover 40 so as to expose an upper surface 101 of the radiating metal foil 10, which is a far infrared heat radiation of the embodiment of the present invention. The tablet 100 can radiate far infrared heat radiation!

And the other side is a closed surface 42 enveloping the soft cover 40, which on the one hand protects the radiation foil 10 and the electric heating film 30, and on the other hand, assists in isolating the resistance generated by the lower surface 302 of the electric heating film 30. The heat is gone!

In another embodiment of the present invention, if the heat insulating effect (insulation coefficient) of the wrapped soft cover 40 is significantly lower, between the electric heating film 30 and the wrapping soft cover 40, and additionally inserting a corresponding size of thermal insulation paper. It is used to isolate or re-reflect it into the electric heating film 30.

As shown in Fig. 1, why is the embodiment of the present invention used to "stick" one electric heating film 30 and one radiation metal foil 10 to each other? Is it not possible to use the two separately?

The answer is yes!

Using the electric heating film 30 alone is like using a "hot towel" as a "hot compress" or "thermal therapy" effect, which allows the consumer to have a distinct "warm" feeling; when using the radiation foil 10 alone, the consumer is not Obviously "warm" feeling.

Furthermore, the way in which the resistive electrothermal film 30 transfers heat is a kind of "thermal conduction"; and the micro-arc oxide film layer of the radiating metal foil 10 maintains the average film thickness below 10 μm, which can effectively transfer heat through the micro-arc The oxide film layer is conducted to the aluminum substrate, The rapid formation of the electric resistance of the electric heating film 30 is a kind of "thermal radiation".

For a long time, the medical community at home and abroad has been quite mature in the mastery and application of "heat" in medical treatment and in theory and technology. In general, in the case of Chinese medicine: the conduction heat effect is a description of the "physical effects associated with the hot compress and hyperthermia of the acupoints of the human body"; and in Western medicine: the radiant heat effect describes the "effect on the human blood microcirculation".

As shown in Fig. 1, if one electric heating film 30 and one radiation metal foil 10 are combined together, the effect of "1+1 is greater than 2" is caused. When far-infrared radiation is applied to human skin tissue by radiant heat, it mainly generates thermal reaction to the microscopic blood vessels of the skin tissue, and the "blood" of microvessels is mostly "water", which is called "far" in biomedicine. Infrared uses the radiant heat to resonate with water. This is the explanation for "promoting blood circulation."

The "resonance" effect of far-infrared energy can be used to decompose large-volume (H ₂ O) n into finer H ₂ O. This fine H ₂ O is easily infiltrated into the blood or other tissue cells through the vascular tube.

As far as we know, water molecules are composed of two hydrogen atoms (with a positive charge) and one oxygen atom (with a negative charge). These three atoms are not in a straight line, but are centered on the oxygen atom to form a bond. A triangular arrangement with an angle of about 105° attracts the hydrogen nuclei of adjacent water molecules, forming a so-called hydrogen bond. The far infrared energy can destroy its hydrogen bond.

To put it simply, the electric heating film 30 and a radiation metal foil 10 are combined to form a "combination product" having a low voltage and low temperature (safety for personal health care) and a significant far-infrared "heat radiation" effect.

In summary, Figure 1 assumes that the radiation foil 10 can convert "resistance heat" into "heat radiation" and has a high emissivity. The main factors are the results of the above-mentioned three samples of ABC by infrared camera. Obviously: it is the superposition effect of the valve metal foil after micro-arc oxidation treatment and then a dip coating sol (film) treatment and electric heating film heating treatment.

Definition 2: The embodiment of the present invention particularly emphasizes that the process of "micro-arc oxidation" and "sol-gel" method is performed by using a valve type thin (soft) sheet; wherein, the embodiment is for aluminum (valve metal) Micro-arc oxidation is used for radiation (far infrared) and thermal (hot therapy) applications in the health care industry; and new and improved technical features, such as Figure 4 dip coating The sol (film) process has not been discovered.

Definition 3: A far infrared heat radiation film according to an embodiment of the present invention, wherein the electric heating film 30 of the device is a resistive electric heating film, which refers to a heat source having an electrical impedance value, as long as the power is turned on. The "thin, soft" material electric heating sheet which generates heat due to its electric resistance value is not limited to the specific material in this embodiment, and heat may be generated as long as it is energized. For example, in this embodiment, a Polyimide Film (PI) ultra-thin electric heating sheet is used. In the embodiment, the manufacturer is made to have a resistance value of 5 ohms. If it is made of 7 ohms or 10 ohms, the thickness is a little harder. There is no particular limitation; and it has the same area size as the metal radiating film 10 in the apparatus of the embodiment, and is mainly advantageous for mutual adhesion forming.

In order to achieve the above-mentioned "low temperature and high emissivity", the embodiments of the present invention are as follows:

Example 1: (1) A thin (soft) sheet of a radiant metal was produced.

Please refer to FIG. 2 , which is a schematic diagram of a manufacturing process of a radiation metal foil according to an embodiment of the present invention.

Steps as shown in Fig. 2: sequentially (1-1) pretreatment, (1-2) microarc oxidation treatment, (1-3) dip coating sol film and cutting appropriate size (1-4 )Measure.

(1-1) Pretreatment: First prepare a thin metal sheet, and polish the surface of the 1050 aluminum alloy with a thickness of 0.1 mm by sandpaper, immerse the oxide film in a 3% sodium hydroxide aqueous solution for several minutes, and then immerse it in acetone. Ultrasonic vibration, then washed and dried with water; (1-2) for micro-arc oxidation treatment: (1-2-1) with 1050 aluminum alloy (100mm × 200mm × 0.1mm) as anode material, stainless steel (190mm × 70mm ×1 mm) as a cathode material. The electrolyte drug was sodium hydroxide (1.6 g/L) reagent grade (Shiji Nippon Pharmaceutical Co., Ltd.) NaOH. Sodium citrate (5.5 g / L) reagent grade Nacalai Na ₂ SiO ₃ 9H2O.

(1-2-2) Using 2 DC powers as the pulse power supply, the anode voltage is controlled at 150V, the cathode voltage is controlled at 500V, the experimental time is controlled for 10min, 15min respectively, and the SPIK can be used to regulate Ton(+), Toff Parameters such as (+), Ton(-), and Toff(-) and pulse current are used to adjust the pulse frequency and waveform.

During the preparation process, a large amount of heat will be released on the surface of the 1050 aluminum alloy, so that the temperature of the electrolyte will The temperature rises rapidly and the electrolyte is evaporated, and the concentration is increased, which affects the temperature of the reaction. Therefore, a 110L ice water circulating stainless steel electrolytic cell is used to solve the large amount of reaction heat released, and the temperature of the solution is controlled to maintain 25 ° C during the preparation process.

After the above-mentioned 1050 aluminum alloy is subjected to micro-arc oxidation treatment, this embodiment is referred to as a metal foil 10A. Different from this, the metal foil 10A is referred to as a radiation metal foil 10 after being subjected to dip coating.

Generally, it can be known in the laboratory environment of the school that in this embodiment, ceramic layers with different film properties can be produced by different electrolyte compositions, and the auxiliary electrolyte can be used to prevent harmful impurities from adsorbing and increasing ceramics. The growth rate of the film layer.

The first paper on the thermal radiation characteristics of the micro-arc oxidation film layer appeared in 2011 [ZWWanga, YMWanga, Y.Liub, JLXuc, LXGuoa, Y.Zhoua, JHOuyanga and JMDai, "Microstructure and infrared emissivity property of coating containing TiO ₂ On titanium alloy by microarc oxidation", Current Applied Physics, Vol. 11, No. 6, pp. 1405-1409, 2011.], the object is a titanium sheet, and the titanium sheet used in the military aerospace engineering needs to be borrowed at a high temperature. Thermal radiation completes the heat transfer. In this paper, a ruthenium electrolyte is used to form a ceramic film with rutile as the main and TiO _{2 as the} auxiliary. The thermal emissivity measured at 700 °C is about 0.9, which is much higher than that of the untreated titanium substrate. In fact, through the design of the composition and structure of the micro-arc oxide film layer, it is possible to take into account the high thermal conductivity of the film layer and high heat radiation.

Reference: M. Al Bosta, KJ Ma & HH Chien, "The effect of MAO processing time on surface properties and low temperature infrared emissivity of ceramic coating on aluminium 6061 alloy" Infrared Physics & Technology, Vol. 60, pp. -334,2013.The micro-arc oxidation alumina ceramic film layer was formed by different process parameters, and the effect of electrolyte temperature on the micro-arc oxidation oxide film layer and the increase of alkaline citrate electrolyte concentration were the most favorable. The radiance of the far infrared rays of the film layer.

(1-2-3) oxidizing the micro-arc to form a good metal foil 10A, wherein the film thickness of the film layer is about When the thickness of the film layer is too thick, the heat conduction property is not good, and even if the micro-arc oxide film layer itself has a high emissivity, the film layer grows too thick, and it is difficult to directly conduct the heat to the oxide film layer. The surface cannot effectively increase the emissivity, and the porosity of the porous layer is about 2 to 2.5%. The metal foil 10A is cut by a slow cutting machine and cut into a size of 80 mm * 160 mm, because the measurement is performed. Avoid the effects of the "edge effect" of the current.

The film roughness measurement was measured using a Mitutoyo, SJ310 surface roughness meter, and the measurement was performed at 5 different positions by 8 cm*16 cm size, and the average surface roughness was recorded.

Please refer to FIG. 3 for the surface topography of the micro-arc oxidized metal foil of the present embodiment; please refer to FIG. 3A for the cross-section of the micro-arc oxidized metal foil of the embodiment; and FIG. 3B is the embodiment. An electron micrograph of the surface of a micro-arc metal foil.

Figure 3 shows a 1000-fold surface topography taken by an Electron Microscope (EM). During this process, the aluminum ions react instantaneously with the oxygen ions in the electrolyte at a high temperature to form a complex structure of alumina deposited on the surface of the metal foil. It can be basically distinguished into a surface porous layer and an inner dense layer.

The surface porous layer structure can be further distinguished into different regions, such as the cross-section of Fig. 3A, which has a porous structure which is caused by the generation of plasma in the same region during the micro-arc process. The thickness of the film affects the resistance of the film. If the resistance of the film is not high enough, the energy easily penetrates the film layer, and the micropores that pass through the energy are formed on the surface. The position of the a.b.c. point micro EDS component analysis is indicated in Figure 3B. The figure indicates the position of the a.b.c. point micro EDS component analysis. In the figure (a), the volcanic pore structure is mainly composed of aluminum and oxygen. In the figure (b), the granular phase structure is mainly composed of yttrium, oxygen and aluminum.

Factors affecting the radiation of the foil 10A: depending on its chemical and physical properties, such as its composition, roughness, porosity and film thickness, etc., wherein: composition: the metal foil 10A produced in the examples, micro-arc oxidation The main composition of the film layer is composed of γ-alumina alumina, and γ-alumina itself has a very wide far-infrared band (11.1μm~33μm), which is supposed to be one of the reasons for the high emissivity of the micro-arc oxide film layer.

Surface roughness: The greater the roughness of the surface, the larger the total surface area of the object, so it will increase the far-infrared radiance. The surface of the metal foil 10A oxidized by micro-arcing is very rough and will be generated on the surface. The structure of the crater and the formation of many "phase structures" near the crater structure are beneficial to increase the surface area and increase the emissivity.

The phase structure of the crucible: when the surface of the metal foil 10A is subjected to the micro-arc reaction, the plasma released from the surface has a high temperature and reacts with the electrolyte in a molten state, and solidifies to cover the surface or It is a spherical phase structure that forms a solidification, so that more particles of cerium oxide and sillimanite can be found in the vicinity of the crater. Silicon dioxide with infrared radiation of different sillimanite, silicon dioxide peak emissivity of 9.6 μ m, 11.4 μ m, 12. Μ m5 ~ 15.3 μ m. The radiance peaks of the meteorites have wavelengths of 10.75 μm , 11.63 μm , 13.16 μm , 15.15 μm, and 8.55 μm to 9.80 μm . Moreover, since the electrolyte used is a bismuth salt, a phase structure of ruthenium is formed during micro-arc oxidation, and is distributed on the surface of the film layer, which also contributes to an increase in the radiance of the film layer.

Please refer to FIG. 4 , which is a schematic diagram of the process of dip coating sol (film) according to the embodiment of the present invention, and FIG. 4 is a schematic view 2 of the dip coating sol (membrane) process of the present embodiment.

As shown in Fig. 4, the dip-coated sol process of this embodiment is a self-made semi-automated machine which mainly has a conveyor track machine 45, and a conveyor belt (not shown) can be moved left and right. A pulley machine 451 for lifting up and down is suspended on the conveyor belt. The pulley machine 451 has two pulleys 4511 which can be moved left and right on the conveyor rail machine 45. The belt of the pulley 4511 is suspended by a hook plate 4512, and the hook plate 4512 is attached to the bottom. A plurality of hooks (not shown) can be hooked to a plurality of metal (aluminum) sheets 10A so that the sheet 10A can be moved "up, down, left, and right".

(1-3-2) Immersion: The semi-automatic control system is enabled, and a plurality of metal foils 10A are placed in a stainless steel container 452, and a commercially available sol liquid (mainly SiO ₂ component) is placed in the container 452, timing ( For example, after 10 minutes), the liquid level is automatically pulled out for a while (for example, 1 minute), because when the metal foil 10A passes through the liquid surface, the coating liquid adheres to the surface due to the viscosity, and thereafter, due to the influence of gravity, The thickness of the partial coating liquid flow drops, and then the metal foil 10A is taken out when the viscosity, the gravity, and the surface tension are balanced.

(1-3-3) Baking (dry): Then the metal foil 10A is automatically transferred to a far-infrared baking lane 453, and the time is adjusted for far-infrared electric heating baking. In this embodiment, the metal foil is found many times. If the sol film on 10A is not completely dried, the film surface is easily scratched by external force, and the film surface is not beautiful.

The above (1-3-3) baking emphasizes the design of the "far infrared baking method" because the initial "hot air convection" method is used for drying, and it is often found that the baking is uneven. If the "far-infrared" method is used for baking, the "far-infrared" radiation will resonate with the water molecules in the sol liquid and the liquid component molecules in the sol liquid. The effect of the resonance heat makes the sol film uniformly heated. Control quality. In short, many experiments have found that "far-infrared" baking is reasonable in both preparation time and investment cost.

(1-3-4) Unloading: The dried foil 10A is transferred to the unloading area, the dried foil 10A is removed (as indicated by the dotted line), and then the un-baked metal is reloaded. Sheet 10A, repeat (1-3-1) process operation until completion acceptance.

Its measurement range is -40~500°C, the wavelength range is 8-14μm, and the accuracy is ±2°C. In order to further understand the radiance of the wavelength range of 4-14 μm, in order to clarify the mechanism of high emissivity, this embodiment also An irradiance map in the range of 4-16 μm can be measured using a Fourier transform infrared spectroscopy FTLA2000 Series Spectrometer. Before the test is carried out, the standard blackbody is first calibrated at 40 ° C and 50 ° C. All measurements are also performed under the same environment and set conditions.

Please refer to FIG. 5 for a schematic diagram of the emissivity spectrum of the preferred embodiment of the present invention.

As shown in Fig. 5, the ordinate indicates the percentage of emissivity (%) and the abscissa indicates the wavelength (unit: micrometer μm). The three infrared absorption bands can be seen in the figure. The micro-arc oxidation-treated aluminum film (as indicated by MAOS in the figure) is compared to the untreated aluminum film (marked by AL in the figure). The spectrum has a significant rise. The infrared radiance of the micro-arc oxide film layer is as described above, depending on the composition of its oxide film layer, such as an oxide of aluminum, an oxide of ruthenium or the like, which affects different infrared wavelength regions.

As shown in Figure 5, the area of three rectangles (indicated by dashed lines). The first one is concentrated in the 6.08 μm region, in which the water molecules are concentrated in the absorption band of 6.08 μm. The second is that the rapidly rising region is between 7 μm and 7.6 μm and the radiation rate is gradually increased. The third region, from 8.6 μm to 14.5 μm, mostly achieves an emissivity of 98%, after which the emissivity value is approximately constant.

The preparation steps are as follows: (2-1) Preparing appropriate specifications: preparing an electric heating film having an appropriate size (combined with the size of the metal foil 10A) whose impedance value is set to 5 ohms; (2-2) connecting a temperature control unit 31: in its electric heating One side of the two sides of the film 30 is provided with a power input port 32, and a temperature control unit 31 is connected to the power line 埠32 and the electric heating film 30, so that the power input 埠32 is input to the power source to control the heat. The heat of the film 30 is in the range of 40 to 50 degrees C (or 42 to 48 degrees C); (2-3) adhesive bonding: on the two sides of the electric heating film 30, there are respectively 3M adhesives on the back; 2-4) The electric heating film 30 is adhered to the lower surface 102 of the radiation metal foil 10: the electric heating film 30 and a temperature control unit 31 connected in series and the same lower surface 302 of an input power source 32 are also The wrapped soft cover 40 is hidden, as shown in Figure 1.

Embodiment 3: (3) Forming a wrapped soft cover.

6 is a front view of a wrapped soft cover 40 according to an embodiment of the present invention; see FIG. 6A is a schematic diagram of a back side of a wrapped soft cover according to an embodiment of the present invention; FIG. 6B is a wrapped soft pull-on strap according to an embodiment of the present invention. FIG. 6 is a schematic view of a wrapped soft cover attachment unit according to an embodiment of the present invention.

The wrapping soft cover 40 of the embodiment of the present invention is completed by the inventors providing the design specifications and entrusting the qualified manufacturer to open the mold.

As shown in Fig. 6, the wrapping soft cover 40 of the present embodiment is a concave surface formed by a flexible soft silicone. The front surface formed by the outer surface has a convex edge as shown in Fig. 6, and the open surface 41 surrounding the circumference; and the rear surface formed as shown in Fig. 6A is a closed plane 42 of a closed plane, or please refer to 1 picture of the package soft cover 40 side view.

The inner surface of the open surface 41 of the front side of the soft cover 40 is used to "nak" the upper surface 101 of the radiation metal foil 10. As shown in FIG. 1, it is a far infrared heat radiation sheet according to an embodiment of the present invention. 100 can radiate "far infrared heat radiation".

And the other side is a closed surface 42 enclosing the soft cover 40, which on the one hand protects the radiation foil 10 and its electric heating film 30; on the other hand, it can not help to isolate the resistance heat generated by the lower surface 302 of the heating film 30. Exude!

Wherein, as shown in Fig. 6A, the rear surface of the closed surface 42 of the soft cover 40 is wrapped, and a plurality of attachment units 43 are additionally provided for assisting the auxiliary element of the far infrared heat radiation sheet 100 to easily adhere to the human body part. As shown in Fig. 6A, the packaged soft cover 40 has two longitudinal attachment units 43 behind it, which can be inserted into an elastic band 431 for use. For example, when it is to be used on the neck, the two ends of the elastic band 431 are adhered to the neck with a fastening tape (or a devil's felt) (not shown), so that the exposed radiation foil 10 on the front side of the soft cover 40 is close to the neck. The cervical vertebrae that need to be illuminated.

In order to facilitate the user to use the soft cover 40, the embodiment of the present invention provides a plurality of different attachments for the attachment unit 43 of the soft cover, as shown in FIG. 6C, which are two different attachments. It is convenient for the user to use, and these different attachments can be defined as the attachment unit 43 to which the embodiment belongs.

Wherein, when the exposed metal foil 10 is exposed to the cervical vertebrae behind the neck, the soft cover is wrapped. The heat generated by the 40 internal heating film 30 can be directly conducted (or radiated) to the surface of the cervical vertebra after passing through the metal foil 10.

The present invention is directed to solving such problems in the case of "the skin is allergic to the heat reaction" or "the person who does not want to be in direct contact with the skin", and in another embodiment, the wrapped soft cover 40 has the exposed radiation foil 10 On the front side, a plurality of side strips 411 made of silicone rubber are added, and a silicone web (not shown) composed of a plurality of side strips 411 may be additionally added for the purpose of "exposed radiation foil 10". It is not in direct contact with the surface of the cervical vertebra because the edge strip 411 (or silicone web) is interposed between the radiating foil 10 and the surface of the cervical vertebra.

If the edge strip 411 (or silicone web) between the radiation foil 10 and the surface of the cervical vertebra will affect the "heat" of the "radiation foil 10", it will be transmitted to the surface of the cervical vertebra.

The answer is: it will not affect.

Because "heat" of "radiation foil 10" is a kind of "heat" of radiation, called heat radiation, which radiates "hot" through space (air).

Embodiment 4: The heat application method of the far-infrared heat radiation film 100 is different from the general far-infrared product described in the prior art: there are two types of heat application of the infrared heat radiation film 100: (1) a single-piece heat application method, that is, a far infrared The heat radiating surface of the heat radiation film 100 "directly" contacts the exposed parts of the human body surface, such as the cervical vertebrae, the waist, the abdomen, the legs, etc., or may also cover the back 42 of the soft cover 40 if necessary. An additional elastic band 43 (as shown in Fig. 6B) is placed around the corresponding cervical vertebrae, waist, abdomen, and leg, and the power is turned on to start the hot compress. (2) The method of using the thermal protection of the protective gear is to directly insert the far-infrared heat radiation film 100 into the general commercially available textile protective gear, and only need to pay attention to: when inserting into the general textile protective gear, the textile protective gear should have a relatively internal Appropriate "mesh gap", the appropriate "mesh gap" is used to "direct" the heat radiation surface of the far infrared heat radiation film 100 (not blocked by the textile protector to the far infrared heat radiation) The area to be illuminated.

The above two methods of use must pay attention to the following points: the far-infrared "hot" radiation applied by the general human body is mostly between 40mW and 60mW/cm ² , and its wavelength is a near-infrared frequency of a long wave compared with a short wave. Short, its energy is hard to penetrate even a thin piece of paper. Therefore, the radiation metal foil 10 and the part of the human body surface that needs to be irradiated must be free of obstacles (such as clothing), that is, the human body surface needs to be illuminated. The part must be "naked".

As described in the foregoing "invention" and the following embodiments of the present invention, it is understood that the method (Way), the function, and the result are disclosed in the prior art. Are not the same.

The method is: using micro-arc oxidation, dip-coated sol, electric heating film and wrapping soft cover, etc., so that an aluminum metal foil can produce unpredictable high emissivity and radiation suitable for human body surface at low temperature. power.

For example, in which an aluminum metal foil is formed into a radiation metal foil 10, the average radiance of the radiation metal foil 10 can be significantly increased from 0.08 of the original aluminum metal thin die to 0.99 when the electric heating film 30 is heated at 45 degrees C. Increase the radiance by about 12 times.

Its function is: its average radiance 0.99 matches the average radiance of the human body 0.99; and its average radiant power is about 40~60mW/cm ² , compared with the prior art, the infrared thermal radiation film 100 is sufficient for the human body to produce reasonable Substantial benefits.

The result is: it has "safe low temperature (electric film 30 plus soft cover 40) and high emissivity (radiation foil 10)", what kind of radiance and radiation power is generated at what temperature, compared to the previous The technology, the features of the "Far Infrared" and the method of use thereof are all described in detail in detail, and the design of the soft sheet is further suitable for "personal and family health care" purposes.
