Description
Technical Field
The invention relates to a heating module with a far infrared physiotherapy function for a human body and application of the heating module in a light wave physiotherapy room.
Background
The light wave bathroom is a third generation health care bath device which is popular in Europe and America, uses far infrared rays of 5.6-15 microns as main energy, adopts the low-temperature sweating technology popular in the world, can easily enjoy music while bathing, and has good health care effect on human bodies. On the surface, the far infrared light wave bathroom is much like a sauna room. The same wooden structure and the same chair, but the working principle is completely different. An electric heating furnace is arranged in the sauna room, high-temperature steam is generated by splashing water, and the steam conducts heat to promote the human body to sweat. The principle of the light wave bathroom is that far infrared radiation is utilized, and because the light wave bathroom is a far infrared radiation source and a far infrared radiation receiver, the far infrared radiation emitted by the light wave bathroom is close to the natural frequency of human cells, so that the far infrared radiation receiver can permeate skin and subcutaneous tissues to 4 cm to 5 cm to generate a resonance effect, so that molecular movement becomes active, and cell movement becomes active accordingly, and the effects of increasing the blood flow speed and accelerating metabolism are achieved. Because the far infrared ray with the frequency only acts on the human body, when the light wave bathroom works, the air is not heated, but the human body can sweat in a low-temperature environment. Since high temperature steam is not required, the light wave bathroom has many advantages over saunas: firstly, the utility model is more comfortable, the air can circulate, no choking feeling exists, and the utility model can also listen to music in the cabin to read books; secondly, the physiotherapy effect of the far infrared wave bathroom has the treatment effect on scapulohumeral periarthritis, cervical spondylosis and other diseases; thirdly, the light wave bathroom is provided with a more convenient temperature adjusting and controlling device, and is more energy-saving than the sauna room.
The far infrared heating device of the light wave house is mainly made of carbon crystal plates and carbon fiber plates and is formed by pressing carbon particles, so far infrared can be released, but a plurality of adhesive materials are added, and the effect is poor. Not near the peak of the human wavelength of 9.6 μm. And, after repeated cold and hot alternation, the cohesiveness of the adhesive material is reduced, so that the power attenuation of the carbon fiber plate starts to appear in 1-3 years, the required temperature cannot be reached, the heating rate is reduced, and the far infrared waves disappear. Combustion can occur, local temperature is too high, heating is uneven due to lamination, local heating is too high, and combustion problems occur. According to the news reports of a plurality of media such as Xinhua net, xinlang financial resources, central Guangdong net and the like, the fire disaster occurs in a foot bath shop in Tiantai county of Zhejiang, 18 people die, 18 people are injured, and investigation results show that the fire disaster is caused by the failure of the conductive part of the electrothermal film on the northwest corner wall of the sweat steaming room No. 2 in the center of the foot bath, so that local overheating is generated, the temperature is continuously increased, and surrounding combustible matters are ignited and spread into a disaster.
The carbon crystal plate and the carbon fiber plate are rough and ugly in appearance, are black opaque hard plates with the thickness of 1-2mm and the rough surface, have the phenomenon of slag falling during use, and cannot meet aesthetic requirements of people while physiotherapy. In addition, the carbon crystal plate and the carbon fiber plate are formed by dissolving carbon powder in a solvent, coating the solvent on an epoxy resin plate, and pressing the epoxy resin plate into the carbon powder-dissolved plate, wherein the gel content is more than 80%, and the space in an optical wave room is greatly polluted and the health of people is damaged in the process of long-time electrifying and heating. Again, such carbon crystal plates, carbon fiber plates, have too high electromagnetic radiation (above 10 μt) which is also detrimental to health.

In the market today, many devices using graphene materials as heating elements mainly utilize the conductivity of graphene. However, the technical capability is not enough, the graphene powder is often combined with other carrier substances, and the graphene powder is often pressed by referring to a carbon fiber plate and the like, or the graphene powder is coated with graphene slurry and then dried, and the graphene powder is black or black brown. First, neither the graphene powder nor the graphene slurry is pure graphene, and a functional group with a hydrogen atom or an oxygen atom is connected to a carbon atom, so that the heating power of the graphene powder or the graphene slurry is equivalent to or lower than that of an existing carbon fiber plate heating body. Further, such a graphene heating element is black and opaque, and is not advantageous over a carbon fiber plate or the like in terms of appearance. The far infrared heating module provided by the invention takes the graphene membrane as a heating body, and the graphene membrane adopted by the invention is a graphene membrane deposited and transferred by the existing vapor deposition method and the like, so that the structure of pure graphene is observed. Therefore, the graphene in the graphene membrane adopted by the invention is colorless and transparent. In addition, the graphene membrane provided by the invention is used as a heating body to generate heat in a surface, is uniform in heating, is high in heating speed and stable in performance, radiates far infrared rays beneficial to human bodies, and has a physiotherapy effect. Because the graphene heating film mainly heats by heat radiation and heat conduction, unlike the traditional heating mode, the graphene heating film does not simply heat air first, but directly warms a human body by the heat radiation, just like the body of a cold person warmed by sunlight in winter. The heating mode does not change the air humidity, and the comfort is better.
Specifically, the far infrared heating module provided by the invention has the following advantages:
1. The appearance is particularly attractive, the whole transparent heating module can be manufactured, the transparency is more than 97%, the glass-like feel is achieved, meanwhile, the thickness of the whole heating film block is only required to be adjusted to be 0.1-0.3 mm in order to meet the use requirement, the purpose of fixing the graphene film can be achieved if the front plate and the edge pressing strip are hard, and the thickness requirement is not high.
2. The heating module is light and thin, has simple production process and is convenient and quick to install.
3. The graphene heating film has the advantages of high heat energy utilization rate, high heating efficiency, energy conservation compared with the traditional heating mode, and no noise during use. The heating effect of 1400W of the carbon crystal/carbon fiber heating body can be achieved by using 1000W of power for the heating film block with the same heating time. The power is reduced by one third, the temperature rising speed is high, and the energy is saved.
4. Electromagnetic radiation is low and international standards below 0.4 mu T can be achieved.
The heating device of the light wave physiotherapy room provided by the invention adopts the far infrared heating module disclosed by the invention, and the generated far infrared wavelength is 5-16 microns, so that the physiotherapy effect is better. The hollow structure design of the heat dissipation plate is more suitable for heat dissipation of the graphene surface, and is favorable for far infrared radiation to human bodies. Besides the function of avoiding people from contacting the heating module, the protective grille can also play a role of radiating far infrared rays to the front in a concentrated way, thereby improving the physiotherapy effect. The decorative board can be designed according to aesthetic requirement, because the transparency of the heating film block is very high, can reach more than 97%, so can very light see and feel the visual enjoyment that the decorative board brought to people, let the light wave house more pleasing to the eye. Simultaneously, the decorative board can select the material that has the reflection far infrared, and the far infrared that the heating film piece was to room wall radiation is to the middle reflection of room, and one can further improve heating efficiency and physiotherapy effect, and two reduce the heating of room wall.
The light wave house heating device provided by the invention is safer, belongs to planar heating, and cannot cause local overhigh temperature; in addition, the graphene transparent membrane is similar to a fuse, is fused under the condition of over-limit voltage or over-high temperature point, and does not generate sparks, meanwhile, the transparent membrane is attractive, the aesthetic appearance of people is met, the peak value of the far infrared radiation wavelength is 9.6 mu m, and the peak value of the far infrared radiation wavelength is the same as that of the human body; and the heating does not emit toxic substances, the electromagnetic radiation is lower than the international standard, and the health of human bodies is not damaged.
