Description

Technical Field

[0001] This invention relates to the field of health cabin technology, specifically a health cabin with oxygenation and heat therapy. Background Technology

[0002] Existing thermotherapy wellness chambers have significant shortcomings in the design and fabrication of their core functional components. The selection of raw materials and the production process of their bio-brick functional modules lack a scientifically standardized system, directly leading to unstable and uneven therapeutic effects. At the raw material formulation level, most rely on empirical ratios without adjusting for terahertz radiation requirements. This fails to effectively enhance the mechanical strength of the bio-bricks or guarantee their structural stability under thermotherapy conditions. This material deficiency prevents the bio-bricks from achieving stable and uniform terahertz radiation, thus hindering the full absorption of bioresonance stimulation by human cells. During use, users experience inconsistent therapeutic intensities on different parts of the body, with some areas failing to achieve effective resonance and failing to repair cell damage at its root. This severely impacts the overall effectiveness of thermotherapy wellness and fails to meet users' core needs for precise and efficient therapy. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a thermotherapy health cabin with oxygenation to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a thermotherapy health cabin with oxygenation, comprising: The cabin has a door installed on the front, a ventilation window installed on the back, a base installed at the bottom, and a cover installed on the top. The health-preserving bed is installed inside the cabin; An oxygen cylinder is installed inside a cabin, and a trolley is provided inside the cabin, with the oxygen cylinder clipped onto the trolley. The bio-brick functional module consists of multiple modules, which are evenly laid at the bottom of the cabin. The bio-brick functional module stably radiates terahertz waves in the 0.1-12THz frequency band.

[0005] Specifically, the bio-brick functional module includes a basic mineral matrix, trace element dopants, and a structural stabilizer. The components, by mass ratio, are: 80-90 parts basic mineral matrix, 5-15 parts trace element dopants, and 2-5 parts structural stabilizer. The basic mineral matrix is ​​selected from at least two of tourmaline, maifanite, and montmorillonite, with a tourmaline to maifanite mass ratio of 3-5:1, providing a natural mineral framework and initial terahertz radiation characteristics. The trace element dopants are composite oxides containing copper, iron, and manganese, with CuO accounting for 30%-40%, Fe2O3 for 40%-50%, and MnO2 for 10%-20%. Doping optimizes the terahertz radiation frequency band of the bio-brick, ensuring coverage of the 0.1-12 THz range. The structural stabilizer is a mixture of sodium silicate and alumina, with a mass ratio of 1-2:1, enhancing the mechanical strength and high-temperature resistance of the bio-brick functional module and preventing cracking or deformation at thermotherapy temperatures. This formulation is the core of the bio-brick functional module to achieve stable terahertz wave radiation, ensuring that the components work synergistically to meet the functional requirements of the health cabin.

[0006] Specifically, the method for manufacturing the bio-brick functional module includes the following steps: Step 1, Raw material pretreatment: Crush the basic mineral matrix to a particle size of 5-10 mm, immerse it in an 8%-12% hydrochloric acid solution at room temperature for 20-30 min to remove surface impurities, wash it with deionized water until neutral, and then dry it at 100-120℃ for 3-4 h; grind the trace element dopant to a particle size of 100-200 nm, mix it with the structure stabilizer, add deionized water to make a suspension with a solid-liquid ratio of 1:5-8, and ultrasonically disperse it for 15-20 min (frequency 25-30 kHz). Step 2, Mixing and Molding: Mix the pretreated basic mineral matrix and suspension in a certain proportion, add 3%-5% water glass as a binder, stir for 30-40 minutes until a uniform paste is formed, pour it into a mold, and press it into shape under a pressure of 10-15MPa to obtain a brick blank; Step 3, sintering and curing: Place the brick blank in a high-temperature sintering furnace, preheat it at 200-300℃ for 2-3 hours to remove moisture and volatile impurities, then raise the temperature to 800-1000℃ and hold it for 4-6 hours for sintering. After naturally cooling to room temperature, cut and trim it to the preset size. Step 4, Performance Optimization: Immerse the sintered bio-brick functional modules in a silane coupling agent (1%-3% ethanol solution by mass) for 1-2 hours, then remove and dry at 80-100℃ for 2-3 hours to complete surface modification and improve terahertz wave radiation stability. This manufacturing method ensures that the bio-brick functional modules possess terahertz wave radiation capability, especially maintaining stable radiation power even when heated to 50℃, meeting the long-term use requirements of the health cabin.

[0007] Specifically, in step 1, the trace element dopant is prepared using a co-precipitation method: copper nitrate, ferric nitrate, and manganese nitrate are dissolved in deionized water in a specific ratio to prepare a mixed solution with a concentration of 0.5-1 mol / L; ammonia water (concentration 25%-28%) is added dropwise to the mixed solution to adjust the pH value to 8-9, generating a hydroxide precipitate; the precipitate is filtered, washed, calcined at 500-600℃ for 2-3 hours, cooled, and then ground to a particle size of 100-200 nm. The co-precipitation method ensures that the trace elements are uniformly mixed to form a stable composite oxide, avoiding localized differences in the radiation performance of the bio-brick due to uneven dopant distribution, and ensuring that the overall radiation of the bio-brick meets the uniform and stable requirements of the test report.

[0008] Specifically, in step 2, the inner wall of the mold used for mixing and molding needs to be polished (surface roughness Ra≤0.8μm) and sprayed with a release agent (material is polytetrafluoroethylene, thickness 5-10μm); during the pressing process, a segmented pressing method is adopted, first pre-pressing at 5-8MPa for 10-15min, then increasing to 10-15MPa and holding for 20-25min. Polishing the mold and the release agent can ensure that the surface of the brick blank is smooth after molding, avoiding damage during demolding. Segmented pressing can make the raw materials more uniformly mixed, reduce the internal voids of the brick blank, and ensure stable terahertz wave radiation performance after subsequent sintering, which meets the requirements for the physical structure and radiation characteristics of the functional modules of bio-bricks.

[0009] Specifically, in step 3, the heating rate for sintering and solidification is controlled at 5-10℃ / min, and the cooling rate is controlled at 3-5℃ / min. During the heating process, the temperature is maintained in the range of 400-500℃ for 1-1.5 hours to adjust the crystal phase and promote the lattice fusion of trace element dopants and basic mineral matrix. After sintering, nitrogen protection cooling is used to prevent oxidation of the surface of the bio-brick functional module. The slow heating and cooling rates and intermediate heat preservation can reduce the internal stress of the brick blank and prevent cracks. Nitrogen protection can maintain the chemical stability of the bio-brick functional module and ensure that its terahertz wave radiation performance will not be degraded due to oxidation in subsequent use.

[0010] Specifically, in step 3, the atmosphere control of the high-temperature sintering furnace adopts a mixture of air and nitrogen, with nitrogen accounting for 60%-70%, and the flow rate of the mixture is controlled at 10-15 L / min. During the sintering and holding stage, the oxygen concentration in the furnace is checked every 1 hour to ensure that the oxygen concentration is ≤5%. The inert gas atmosphere can reduce the oxidation loss of trace elements (copper, iron, manganese) in the bio-brick functional modules at high temperatures, avoid changes in the crystal structure caused by element oxidation, and thus affect the terahertz wave radiation frequency band, ensuring that the bio-brick functional modules can stably radiate waves in the 0.1-12 THz frequency band after sintering.

[0011] Specifically, in step 4, the silane coupling agent used for surface modification is amino-silane, and the mass fraction of the silane coupling agent in the ethanol solution is 2% - 2.5%; magnetic stirring (rotation speed 200 - 300 r / min) is adopted during the soaking process to ensure that the surface of the bio-brick functional module is evenly covered with the coupling agent; after drying, the contact angle of the surface of the bio-brick functional module needs to be detected, and a contact angle ≥ 90° is qualified, ensuring that it has a certain hydrophobicity to avoid moisture absorption in a humid environment and affecting its performance. The modification with amino-silane coupling agent can enhance the interfacial stability between the bio-brick functional module and air, reduce the interference of water vapor on terahertz wave radiation, and at the same time, the hydrophobic design can extend the service life of the bio-brick functional module and ensure that its radiation power always meets the numerical range in the detection standard.

[0012] Specifically, a protective coating is provided on the surface of the bio-brick functional module. The protective coating is made of transparent polyimide material with a thickness of 5 - 10 μm, and is coated by spraying process and dried at 80 - 100 °C for 1 - 2 h; the light transmittance of the protective coating ≥ 90%, and it does not affect the penetration and radiation of terahertz waves, and at the same time has wear resistance (hardness ≥ HB) and temperature resistance (-20 - 100 °C) characteristics. The protective coating can protect the surface of the bio-brick from scratches or stain contamination, maintain its surface cleanliness, avoid impurity coverage from affecting terahertz wave radiation, and at the same time does not interfere with the radiation performance and extends the service life of the bio-brick functional module.

[0013] Specifically, the bio-brick functional module further includes a flexible graphene heating sheet (power 30 - 50 W, thickness 0.1 - 0.2 mm), which is pasted on the back of the bio-brick functional module through high-temperature resistant glue, and the flexible graphene heating sheet is electrically connected to the central control system; when the central control system detects that the surface temperature of the bio-brick functional module is lower than 25 °C, the flexible graphene heating sheet is automatically started to maintain the temperature of the bio-brick functional module at 25 - 50 °C, and the terahertz wave radiation power is monitored in real time during the heating process to ensure that the power fluctuation ≤ 10%. It can avoid the decrease of the radiation power of the bio-brick functional module caused by a low-temperature environment, keep it in a stable radiation state at normal temperature and 50 °C during heating, and solve the problem of low-temperature performance attenuation of traditional terahertz devices.

[0014] The beneficial effects of the present invention: The bio-brick functional module adopts a clear design of component mass ratio. The basic mineral matrix, trace element dopant and structure stabilizer act synergistically. The basic mineral matrix provides a natural radiation framework, the trace element dopant optimizes the radiation frequency band, and the structure stabilizer enhances the mechanical strength and high-temperature resistance, ensuring stable radiation of terahertz waves in the 0.1 - 12 THz frequency band and meeting the needs of bio-resonance physiotherapy.

[0015] Trace element dopants are prepared by co-precipitation to ensure uniform mixing of all elements; the mixing and molding process uses segmented pressure and polishing molds to reduce internal voids and surface damage in the brick blanks; multiple bio-brick functional modules are evenly laid at the bottom of the chamber to form a uniform terahertz wave field throughout the chamber, avoiding insufficient local radiation intensity or frequency shift, so that all parts of the human body can receive balanced physical therapy and enhance the bio-resonance effect.

[0016] The flexible graphene heating pad on the back of the bio-brick functional module is linked to the central control system. When the temperature of the bio-brick functional module is detected to be below 25℃, it will automatically start to maintain the temperature between 25-50℃. It also monitors the radiation power in real time to ensure that the fluctuation is ≤10%, which solves the problem of low-temperature performance degradation of traditional equipment. It is suitable for use in different seasons and regions and ensures stable physiotherapy effects.

[0017] By continuously supplying oxygen through oxygen tanks, combined with thermotherapy and terahertz wave therapy, a triple health-preserving mechanism of oxygen supply, thermotherapy, and cell resonance repair is formed. Oxygen provides sufficient raw materials for cell metabolism, thermotherapy promotes blood circulation, and terahertz waves repair cell damage. The three work together to improve the body's condition from multiple dimensions and enhance the efficiency of health preservation. Attached Figure Description

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1-4This invention provides a technical solution: a thermotherapy health cabin with oxygenation, comprising a cabin body 100, a cabin door 200 installed on the front of the cabin body 100, a ventilation window 201 installed on the back of the cabin body 100, a base 101 installed at the bottom of the cabin body 100, and a top cover 102 installed on the top of the cabin body 100; a health bed 500 is disposed inside the cabin body 100; an oxygen tank 400 is disposed inside the cabin body 100, and a trolley 401 is provided inside the cabin body 100, with the oxygen tank 400 snapped onto the trolley 401; multiple bio-brick functional modules 300 are provided, and the multiple bio-brick functional modules 300 are evenly laid at the bottom of the cabin body 100, with the bio-brick functional modules 300 stably radiating terahertz waves in the 0.1-12THz frequency band.

[0021] The bio-brick functional module 300 also includes a flexible graphene heating element (power 30-50W, thickness 0.1-0.2mm), which is attached to the back of the bio-brick functional module 300 with high-temperature resistant adhesive. The flexible graphene heating element is electrically connected to the central control system. When the central control system detects that the surface temperature of the bio-brick functional module 300 is lower than 25℃, it automatically activates the flexible graphene heating element to maintain the temperature of the bio-brick functional module 300 at 25-50℃. During the heating process, the terahertz wave radiation power is monitored in real time to ensure that the power fluctuation is ≤10%. This avoids the decrease in radiation power of the bio-brick functional module 300 due to low temperature environments, ensuring that it maintains a stable radiation state at room temperature and 50℃, thus solving the problem of low-temperature performance degradation of traditional terahertz equipment. Through continuous oxygen supply via oxygen tank 400, combined with thermotherapy and terahertz wave therapy, a triple health-preserving mechanism of oxygen supply, thermotherapy, and cell resonance repair is formed. Oxygen provides sufficient raw materials for cell metabolism, thermotherapy promotes blood circulation, and terahertz waves repair cell damage. The three work synergistically to improve the body's condition from multiple dimensions and enhance health-preserving efficiency.

[0022] The bio-brick functional module 300 includes a basic mineral matrix, trace element dopants, and structural stabilizers. The components, by mass ratio, are: 80-90 parts basic mineral matrix, 5-15 parts trace element dopants, and 2-5 parts structural stabilizers. The basic mineral matrix is ​​selected from at least two of tourmaline, maifanite, and montmorillonite, with a tourmaline to maifanite mass ratio of 3-5:1, providing a natural mineral framework and initial terahertz radiation characteristics. The trace element dopants are composite oxides containing copper, iron, and manganese, with CuO accounting for 30%-40%, Fe2O3 for 40%-50%, and MnO2 for 10%-20%. Doping optimizes the terahertz radiation frequency band of the bio-brick, ensuring coverage of the 0.1-12 THz range. The structural stabilizers are a mixture of sodium silicate and alumina, with a mass ratio of 1-2:1, enhancing the mechanical strength and high-temperature resistance of the bio-brick functional module 300 and preventing cracking or deformation under thermotherapy temperatures. This compositional formula is the core of the Bio-Brick Functional Module 300's stable terahertz wave radiation, ensuring that each component works synergistically to meet the functional requirements of the health cabin. The Bio-Brick Functional Module 300 adopts a well-defined component mass ratio design, with the basic mineral matrix, trace element dopants, and structural stabilizers working synergistically. The basic mineral matrix provides a natural radiation framework, the trace element dopants optimize the radiation frequency band, and the structural stabilizers enhance mechanical strength and high-temperature resistance, ensuring stable radiation of terahertz waves in the 0.1-12THz frequency band to meet the needs of bioresonance therapy.

[0023] The manufacturing method of the bio-brick functional module 300 includes the following steps: Step 1, raw material pretreatment: The basic mineral matrix is ​​crushed to a particle size of 5-10 mm, soaked in an 8%-12% hydrochloric acid solution at room temperature for 20-30 minutes to remove surface impurities, washed with deionized water until neutral, and then dried at 100-120℃ for 3-4 hours; the trace element dopant is ground to a particle size of 100-200 nm, mixed with a structural stabilizer, and then added to deionized water to prepare a suspension with a solid-liquid ratio of 1:5-8. Sound dispersion for 15-20 minutes (frequency 25-30kHz); the preparation of trace element dopants adopts the co-precipitation method: copper nitrate, ferric nitrate, and manganese nitrate are dissolved in deionized water in proportion to prepare a mixed solution with a concentration of 0.5-1 mol / L; ammonia water (concentration 25%-28%) is added dropwise to the mixed solution to adjust the pH value to 8-9, generating hydroxide precipitate; after filtering and washing the precipitate, it is calcined at 500-600℃ for 2-3 hours, cooled, and ground to a particle size of 100-200 nm. The co-precipitation method can ensure that the trace elements are uniformly mixed to form a stable composite oxide, avoiding the difference in local radiation performance of the bio-brick due to uneven distribution of dopants, and ensuring that the overall radiation of the bio-brick meets the requirements of uniformity and stability in the test report; Step 2, Mixing and Molding: Mix the pretreated basic mineral matrix and suspension in a certain proportion, add 3%-5% water glass as a binder, stir for 30-40 minutes until a uniform paste is formed, pour into a mold, and press under 10-15 MPa pressure to obtain a brick blank; the inner wall of the mold used for mixing and molding needs to be polished (surface roughness Ra≤0.8μm) and sprayed with a release agent (material is polytetrafluoroethylene, thickness 5-10μm); during the pressing process, a segmented pressing method is adopted, first pre-pressing at 5-8 MPa for 10-15 minutes, then increasing to 10-15 MPa and holding for 20-25 minutes. Polishing the mold and the release agent can ensure that the surface of the brick blank is smooth after molding, avoiding damage during demolding. Segmented pressing can make the raw materials more uniformly mixed, reduce the internal voids of the brick blank, and ensure stable terahertz wave radiation performance after subsequent sintering, which meets the requirements of the physical structure and radiation characteristics of the bio-brick functional module 300; Step 3, Sintering and Curing: Place the brick blank in a high-temperature sintering furnace, preheat at 200-300℃ for 2-3 hours to remove moisture and volatile impurities, then raise the temperature to 800-1000℃ and hold for 4-6 hours for sintering. After naturally cooling to room temperature, cut and trim to the preset size. The heating rate for sintering and curing is controlled at 5-10℃ / min, and the cooling rate is controlled at 3-5℃ / min. During the heating process, stay in the 400-500℃ range for 1-1.5 hours to adjust the crystal phase and promote the lattice fusion of trace element dopants and basic mineral matrix. After sintering, use nitrogen protection cooling to avoid oxidation of the surface of the bio-brick functional module 300. The slow heating and cooling rate and intermediate heat preservation can reduce the internal stress of the brick blank and prevent cracks. Nitrogen protection can maintain the chemical stability of the bio-brick functional module 300 and ensure that its terahertz wave radiation performance will not be degraded due to oxidation in subsequent use. The atmosphere control of the high-temperature sintering furnace adopts a mixture of air and nitrogen, with nitrogen accounting for 60%-70%, and the flow rate of the mixture is controlled at 10-15 L / min. During the sintering and holding stage, the oxygen concentration in the furnace is checked every 1 hour to ensure that the oxygen concentration is ≤5%. The inert gas atmosphere can reduce the oxidation loss of trace elements (copper, iron, manganese) in the bio-brick functional module 300 at high temperatures, avoid changes in the crystal structure caused by element oxidation, and thus affect the terahertz wave radiation frequency band, ensuring that the bio-brick functional module 300 can stably radiate waves in the 0.1-12THz frequency band after sintering. Step 4, Performance Optimization: Immerse the sintered bio-brick functional module 300 in a silane coupling agent (1%-3% by mass ethanol solution) for 1-2 hours, then remove and dry at 80-100℃ for 2-3 hours to complete surface modification and improve terahertz wave radiation stability. This manufacturing method ensures that the bio-brick functional module 300 has terahertz wave radiation capability, especially maintaining stable radiation power even under heating to 50℃, meeting the long-term use requirements of the health cabin; the silane coupling agent used for surface modification is aminosilane, and the mass fraction of the silane coupling agent in the ethanol solution is 2%-2.5%; during the immersion process, magnetic stirring (200-300 r / min) is used to ensure that the surface of the bio-brick functional module 300 is uniformly covered with coupling agent; after drying, the contact angle of the surface of the bio-brick functional module 300 needs to be tested, and a contact angle ≥90° is acceptable, ensuring that it has a certain degree of hydrophobicity and avoiding moisture absorption in humid environments that would affect performance. Modification with aminosilane coupling agent can enhance the interfacial stability between the bio-brick functional module 300 and air, reduce the interference of water vapor on terahertz wave radiation, and extend the service life of the bio-brick functional module 300 by hydrophobic design, ensuring that its radiation power meets the numerical range in the testing standard for a long time.

[0024] The surface of the bio-brick functional module 300 is coated with a protective coating made of transparent polyimide, 5-10 μm thick, applied using a spraying process and dried at 80-100℃ for 1-2 hours. The protective coating has a light transmittance of ≥90% and does not affect the penetration and radiation of terahertz waves. It also possesses wear resistance (hardness ≥HB) and temperature resistance (-20-100℃). The protective coating protects the surface of the bio-brick from scratches or stains, maintaining its surface cleanliness and preventing impurities from affecting terahertz wave radiation. It also does not interfere with radiation performance, extending the service life of the bio-brick functional module 300. Trace element dopants are prepared using a co-precipitation method to ensure uniform mixing of all elements. The mixing and molding process employs segmented pressure and polishing molds to reduce internal voids and surface damage in the brick blank. Multiple bio-brick functional modules 300 are evenly laid at the bottom of the chamber 100, forming a uniform terahertz wave field throughout the chamber. This avoids insufficient local radiation intensity or frequency shift, allowing all parts of the body to receive balanced therapy and enhancing the bioresonance effect.
