Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to an infrared physiotherapy device based on infrared radiation heating from photonic crystals. Background Technology

[0002] Infrared therapy lamps are frequently used in clinical settings, physiotherapy clinics, and homes. They promote local wound healing, treat post-operative wounds, and alleviate symptoms of chronic conditions such as arthritis, frozen shoulder, and lower back and leg pain. Infrared therapy devices based on photonic crystal infrared radiation heating can effectively promote local blood circulation, improve blood flow, and enhance local nutrient supply. When operating, these devices emit infrared rays that penetrate the skin, generating a thermal effect in muscles and subcutaneous tissues. This accelerates blood circulation, speeds up metabolism, reduces pain, and promotes muscle relaxation.

[0003] The main types of existing infrared therapy lamps are:

[0004] 1. TDP infrared heating lamps utilize a special manufacturing process to create a composite coating radiation plate (treatment plate / element plate). An electric heating device directly heats the radiation plate, causing the elements within it to generate a specific range of electromagnetic waves (mid-infrared and far-infrared) at a certain temperature (above 280℃). This radiation plate irradiates the area requiring treatment, helping to improve blood circulation, promote blood flow, and relax muscles and tendons. Clinically, it can play a role in treating diseases and maintaining health. However, this technology results in problems such as an excessively heavy lamp head and inconvenient adjustment.

[0005] 2. Infrared therapy lamps utilize a halogen bulb mounted on the lamp head housing. The infrared radiation from a halogen lamp is the thermal radiation inevitably produced when a tungsten filament is heated to an extremely high temperature (approximately 3000K) by an electric current. At this temperature, most of the energy radiated by an object is concentrated in the infrared band, with a peak in the near-infrared region. Halogen lamps convert most of the electrical energy (approximately 80%) into heat energy (infrared radiation), with only a small portion (approximately 20%) converted into visible light.

[0006] However, existing infrared therapy lamps still have the following problems and limitations: 1) Inconvenient product installation; 2) Long heating time and slow heating speed, requiring waiting time for patients and affecting their experience; 3) The lamp head is too heavy, making it inconvenient for patients to adjust the irradiation angle; 4) Traditional halogen lamps have a lifespan of only 3-5 years, which is too short; 5) Low temperature control accuracy and uneven heating, which can easily cause local low-temperature burns to patients; 6) They all transfer energy through indirect heating, resulting in low heat conversion efficiency.

[0040] Specifically, the working principle and process of this utility model are as follows:

[0041] This invention utilizes a photonic crystal infrared radiation heating coating applied to the front wall of an infrared radiation heater. A photonic crystal is a material with a periodic refractive index or dielectric constant. The periodic structure of the photonic crystal can interact with the plasmon resonance effect on the surface of a metal thin film, thereby enhancing light of a specific wavelength on the surface. By adjusting the structural parameters of the photonic crystal, the resonant frequency can be modulated, thus exciting the radiation of infrared light. Furthermore, by changing the lattice size of the photonic crystal, the emitted infrared band can be flexibly controlled, achieving spectral tuning.

[0042] This invention utilizes a three-dimensional photonic crystal infrared radiation heating coating, incorporating a photonic bandgap and targeting the infrared absorption peaks of different materials to achieve efficient heating in specific wavelengths. It leverages the infrared radiation effect of the photonic crystal to achieve high efficiency, low energy consumption, and uniform heating. Simultaneously, the precise control of the infrared wavelength and temperature, combined with the lightweight design of the infrared therapy device, solves the problems of low thermal efficiency, slow response, poor temperature control accuracy, and short lifespan associated with traditional heating lamps.

[0043] This invention features a novel and unique structural design, is convenient and reliable to use, and boasts higher thermal energy conversion efficiency. Compared to traditional infrared heating technologies (such as halogen lamps), it can generate heat more quickly and evenly. The concentrated and stable energy of infrared radiation significantly enhances the heating effect and provides excellent health benefits to the human body, improving microcirculation, promoting metabolism, and boosting immunity.

[0044] This utility model has the following advantages:

[0045] 1) The electrothermal radiation conversion efficiency is >85%, which is much higher than that of traditional halogen lamps (50%) and ordinary carbon-based electrothermal materials (60%).

[0046] 2) Rapid response: Heating time <60 seconds (traditional halogen lamps require 5~10 minutes), achieving "on-demand heating" and reducing energy consumption by 40%~70%.

[0047] 3) Temperature uniformity: High-precision temperature control of ±3℃ (the traditional solution is ±10℃) to avoid local overheating or low-temperature waxing.

[0048] 4) Safety and long lifespan: 5-220V power supply design, no risk of leakage. Fully sealed packaging technology, lifespan > 10 years (traditional halogen lamp lifespan 3-5 years).

[0049] 5) Excitation temperature of the heating lamp: The working temperature is 30~500℃ (customizable). It achieves efficient infrared heating through the reflection effect of photonic crystal, reducing energy consumption by 40%.

[0050] 10~300W (near-infrared band, penetration depth 3~5mm), suitable for the safety requirements of physiotherapy scenarios.

[0051] 6) It only takes 10 seconds for the target object (such as skin or pipe) to rise from room temperature to 40°C.

[0052] 7) The temperature is fully adjustable, primarily achieved through adjusting the heating power for precise temperature control. A target temperature can be set via the temperature control system, and the power can be adjusted to maintain a stable temperature output. The adjustable range is from room temperature to 500℃, and the main adjustment factors are power and frequency band selection.

[0053] 8) Infrared bands can be customized by changing the size and materials of micro / nano particles. Infrared bands that can be generated include:

[0054] Near-infrared 0.75-1.1μm

[0055] Mid-infrared 2.5-4.0μm

[0056] Far-infrared wavelength 8.0-9.5μm and can be precisely adjusted in infrared band.

[0057] 9) The film is only 0.5 mm thick, which can be fitted to curved surfaces (such as the curved shell of a heat lamp), eliminating the need for a metal infrared radiation heater and allowing for greater design freedom. This solves the problem of excessive weight of the lamp head caused by existing technologies.

[0058] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
