Description

Technical Field

[0001] The invention relates to the technical field of infrared therapy equipment, and more particularly to a multifunctional leg infrared therapy fumigation massage equipment. Background Art

[0002] In recent years, infrared (IR) physiotherapy equipment has been increasingly used in the field of clinical health care and rehabilitation. Different bands of infrared radiation (including near infrared, mid-infrared and far infrared) have different focuses on the physiological mechanisms and physiotherapy effects of the human body:

[0003] Near infrared (IR-A)

[0004] The wavelength is short (about 0.7-1.4μm) and has relatively strong penetration, which can directly reach deep muscles, joints and other tissues. Clinical studies have shown that near infrared has a significant effect on promoting cell activation, improving mitochondrial function and accelerating tissue repair.

[0005] It is often used in rehabilitation therapy to relieve symptoms such as deep muscle soreness, joint inflammation and local swelling.

[0006] Mid-infrared (IR-B)

[0007] The wavelength is about 1.4-3.0μm, and the penetration depth and thermal effect are between near infrared and far infrared. Its thermal effect is relatively mild, and it is often used to provide stable heating in the skin and shallow tissues, and combined with other functions (such as steam fumigation) to improve local circulation and assist in the penetration of liquid medicine.

[0008] Far infrared (IR-C)

[0009] The wavelength is about 3.0-14μm (or longer), and it mainly acts on the surface of the skin and nearby tissues, which can produce a soothing and uniform thermal effect, promote microcirculation and metabolism. It is widely used in the fields of relieving superficial pain, keeping warm and health care, and assisting blood circulation.

[0010] With the in-depth study of infrared biological effects, devices that use single or dual-band infrared lamps for foot massage, leg health care or whole body physiotherapy have appeared on the market. Some devices have also added steam and massage functions on the basis of thermal therapy, in order to achieve multi-dimensional rehabilitation and health care. However, overall, the existing technology still has obvious shortcomings in multi-band infrared coordination, temperature and humidity linkage control, and convenience of human-computer interaction.

[0011] Problems of existing technologies: 1. Single or simple infrared band layout, lack of coordination between deep and surface layers

[0012] Most of them only use single or dual-band infrared radiation (such as only far infrared or near + far infrared), and cannot take into account both deep rapid warming and surface gentle health care in the same device, resulting in limited therapeutic effects on joints or deep muscles, or insufficient superficial health care.

[0013] 2. Insufficient connection between steam and infrared functions

[0014] Some footbaths and therapy tubs have added steam functions, but they are often simply a combination of steam heating and infrared heating, lacking refined linkage in terms of temperature, humidity and light intensity. During use, problems such as temperature overshoot, local excessive temperature or improper humidity are prone to occur, which not only affects comfort, but also makes it difficult to give full play to the advantages of steam-assisted liquid penetration.

[0015] 3. Lack of synchronous control of massage and heat therapy

[0016] In existing similar products, the massage module and infrared heat therapy usually operate separately, or lack the rhythm management of "first deep rapid heating, then surface soothing massage". As a result, the temperature is still uneven during massage, the deep layer is not fully relaxed, and better physical therapy effects cannot be achieved, and there may even be safety hazards such as excessive local stimulation and heat accumulation.

[0017] 4. Insufficient integrated design and functional integration

[0018] When a device tries to combine functions such as "infrared + steam + massage", it often faces technical difficulties such as insufficient compactness of the internal structure, imperfect electrical safety and waterproof design, and interference between the three functions. This results in the device being bulky, reliability being difficult to guarantee, and it being difficult to form a truly multifunctional integrated physiotherapy product. Summary of the invention

[0019] In order to overcome the shortcomings of the existing technology, the present invention provides a multifunctional leg infrared physiotherapy fumigation massage device, which effectively solves the shortcomings of traditional physiotherapy equipment in multi-band infrared coordination, temperature and humidity control, massage coordination, and structural integration, and provides a safer, more comfortable and efficient multi-dimensional physiotherapy solution for the elderly and other people who need leg rehabilitation care. This technical solution has broad application value and promotion prospects in the fields of clinical rehabilitation, family health care and health preservation. .

[0020] To achieve the above object, the present invention provides the following technical solutions:

[0021] A multifunctional leg infrared physiotherapy fumigation massage device, which has three infrared band light sources, namely near infrared, mid-infrared and far infrared, and has a built-in steam generator and a leg massage mechanism; the device uses an integrated control system to start and stop the three-band infrared light sources in sections or in parallel, and to perform multi-channel linkage control on steam output and massage programs;

[0022] The near-infrared IR-A light source is used for rapid temperature increase and thermal therapy of deep joints and muscles; the mid-infrared IR-B light source is combined with steam fumigation to maintain a mild and uniform thermal environment; the far-infrared IR-C light source is mainly used for surface soothing and improving microcirculation.

[0023] In a specific embodiment, the integrated control system includes a temperature sensor, an infrared radiation / light intensity sensor and a humidity sensor. The data collected by the sensors are analyzed in real time through a software algorithm, and the power output of the three-band infrared light source, the steam volume of the steam generating device, and the operating frequency and strength of the massage mechanism are adjusted in a linked manner.

[0024] In a specific embodiment, the near-infrared IR-A light source has a high power density and strong penetration, and is used for the initial rapid temperature rise stage or for enhanced heat therapy of deep sore areas;

[0025] The mid-infrared IR-B light source operates at medium power and cooperates with the steam function to provide gentle and gradual heat transfer;

[0026] The far infrared IR-C light source is distributed on the surface area of ​​the legs with low to medium power for continuous warmth preservation, microcirculation improvement and later relaxation.

[0027] In a specific embodiment, it also includes an infrared radiation / light intensity sensor installed inside the device or near the lamp group, which is used to detect the actual emission power of the infrared lamp; when it is detected that the light intensity of a certain band of lamp sources exceeds a safety threshold, the control system automatically reduces the power or stops the corresponding light source to prevent burning or scalding caused by excessive radiation.

[0028] In a specific embodiment, the steam generating device and the three-band infrared lamp source are arranged in partitions through a heat-insulating and moisture-insulating structure to prevent steam from directly impacting or affecting the circuit and heating elements; an exhaust port is provided on the inner wall or top of the equipment to allow the steam to circulate evenly in the barrel.

[0029] In a specific embodiment, the massage mechanism adopts roller massage or air bag massage and is arranged on the sole of the foot or around the barrel wall.

[0030] In a specific embodiment, a variety of physical therapy modes are preset in the integrated control system, including joint relief mode, deep relaxation mode, quick relief mode, and full-process comprehensive mode; users can select or modify parameters on a single human-computer interaction interface or APP, and start the corresponding physical therapy process with one click.

[0031] In a specific embodiment, the integrated human-computer interaction interface can display the temperature inside the barrel, the infrared lamp band power, the massage intensity, the steam volume and the remaining treatment time in real time, and is equipped with a voice prompt or alarm function.

[0032] In a specific embodiment, the device uses a waterproof, moisture-proof and high-temperature resistant ceramic heating plate or a corresponding infrared lamp tube inside;

[0033] The spatial angle arrangement and power distribution of the three-band light source have been optimized to avoid excessive superposition of infrared energy and formation of hot spots in the same local area, thereby enhancing the balance and comfort of the overall physical therapy.

[0034] In a specific implementation, the device has multi-point temperature / humidity / light intensity detection and adopts an independent drive circuit or multi-channel power supply. Through electromagnetic compatibility EMC design and isolation layer protection, the infrared lamp group, steam system and massage mechanism can operate safely without interfering with each other, thus forming a feasible and stable product solution.

[0035] This patent proposal proposes a multifunctional physiotherapy device that deeply integrates three-band synergistic physiotherapy of near infrared (IR-A), mid infrared (IR-B) and far infrared (IR-C) with steam fumigation, leg massage and other functions. By systematically planning the lighting angles, power distribution and heat insulation and waterproof measures of the three infrared bands in the hardware design, and realizing closed-loop monitoring and multi-channel control of temperature, humidity and infrared light intensity at the software level, it can:

[0036] Layered therapy: A "segmented" thermal therapy mode that uses near-infrared deep penetration for preheating, mid-infrared transition and far-infrared surface health care, taking into account both deep and surface needs.

[0037] Steam synergy: cooperates with mid-infrared and far-infrared in a suitable temperature and humidity range to help open pores, promote the penetration of herbal liquid or care medium, and further enhance the therapeutic effect.

[0038] Integrated safety and control: Through multi-point sensor monitoring of temperature, humidity and infrared radiation intensity, the intelligent algorithm can timely adjust the power or steam output of each band; combined with a user-friendly operation interface and preset modes, it reduces the risk of misoperation by elderly users.

[0039] Multifunctional integration: Infrared lamp group, steam generator, massage mechanism and corresponding exhaust and moisture-proof devices are compactly arranged in the same barrel structure to ensure that various functions work together and operate stably, which not only improves the convenience of use, but also significantly enhances the comprehensive effectiveness of physical therapy.

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] The following is a detailed description of a specific embodiment thereof.

[0047] Embodiment 1:

[0048] Single interface user free control mode

[0049] Users can select infrared bands (near, medium and far infrared), steam functions and massage modes (intensity, roller speed, airbag rhythm, etc.) on the control panel, and start with one button or adjust at any time during the treatment.

[0050] The interface provides a clear display of parameters such as temperature, time, and massage intensity, and comes with voice / text prompts, reducing the risk of confusion or misoperation for elderly users caused by complex operations.

[0051] Multiple preset modes

[0052] The system has built-in multiple preset programs (such as "joint relief mode" and "fatigue relief mode", etc.), integrating the combination logic of different bands of infrared, steam and massage, allowing the elderly and caregivers to quickly call up appropriate physical therapy processes, further improving convenience and safety of use.

[0053] Joint relief mode

[0054] Deep relaxation mode

[0055] Quick relief mode

[0056] Fully integrated model

[0057] Multi-band infrared work coordination

[0058] Innovative combination of three-band infrared synergistic therapy

[0059] Multi-band collaborative technology

[0060] The three-band synergistic physiotherapy scheme of near infrared (IR-A), mid infrared (IR-B) and far infrared (IR-C) adopted by the present invention is optimized at the hardware structure and control system level, so that the three bands can work in time-sharing mode to achieve multi-stage thermal therapy of "deep layer-middle layer-surface layer", and can also be used in parallel at specific stages to enhance the overall physiotherapy performance. This technical means not only provides the rapid thermal therapy function of joints and deep muscles, but also takes into account the comfort and safety required for mild surface physiotherapy.

[0061] Different from the single or simple dual-band application in the existing technology, it truly realizes the full-process thermal therapy mode of "fast preheating + gentle transition + surface relief", which can effectively solve the pain point of traditional equipment that is difficult to take into account both deep physiotherapy and surface gentle health care. This multi-band linkage technology has significant innovation and practical value in both hardware design and software control, and is suitable for application in a wide range of scenarios such as leg health care and rehabilitation therapy for the elderly.

[0062] Near infrared (IR-A) time-sharing: fast warm-up and deep conditioning

[0063] Due to its short wavelength and strong penetrating power, near-infrared can quickly increase the temperature of deep leg tissue in the initial stage of physical therapy, helping elderly users relieve joint pain and accelerate local blood circulation.

[0064] When the target temperature is detected or the user has reached the initial "warm-up" requirement, the system can automatically switch to other bands according to the set strategy to avoid over-stimulation of deep tissue.

[0065] Mid-infrared (IR-B) gentle transition: gradual heating and fumigation promotion

[0066] The mid-infrared light source preset inside the device, combined with the steam or liquid fumigation function, can take over and maintain a comfortable heating level for the legs after the deep layers have been activated by near-infrared.

[0067] Through the cross-effect of mid-infrared and moderate steam, a more uniform heat transfer can be achieved, which helps the elderly to gradually adapt to the heat while avoiding the discomfort or risk of burns caused by traditional rapid heating.

[0068] Far infrared (IR-C) surface soothing: microcirculation improvement and health care consolidation

[0069] The far infrared band is known for its relatively gentle thermal radiation, which mainly acts on the skin and superficial tissues.

[0070] In the second half of the physical therapy or massage stage, the use of far-infrared light sources can further consolidate the effects of the entire thermal therapy, promote sweating, relieve surface muscle fatigue, and have a mild relieving effect on common geriatric symptoms such as leg rheumatism and joint soreness.

[0071] Software system for refined control of multi-band light groups

[0072] In order to give full play to the "superposition effect" of the three bands, the present invention sets a variety of physical therapy modes in the control program:

[0073] Sequential therapy mode: near infrared preheating + medium infrared slow transition + far infrared late soothing;

[0074] Parallel overlay mode: Multi-band light groups are turned on simultaneously within a specific time period to achieve a combination of rapid heating and surface maintenance.

[0075] The system performs closed-loop regulation based on real-time data collected by sensors (temperature, humidity, infrared light intensity), dynamically adjusting the power output or start and stop time of each lamp group to ensure that the entire physical therapy process is safe, comfortable and efficient.

[0076] Technical effects and advantages

[0077] Taking both deep and surface layers into consideration: Compared with traditional single-band devices that only heat the surface of the skin or local areas, this system can achieve comprehensive physical treatment of joints, deep muscles and superficial skin in the same device.

[0078] Avoid sudden temperature changes or excessive stimulation: In time-sharing mode, elderly users can receive therapy step by step, significantly reducing the risk of sudden burns or excessive irritation.

[0079] Combined fumigation and massage function: Through multi-band coordination and parallel regulation of steam, massage and other modules, a "full-process physical therapy" closed loop is formed from rapid preheating to gentle consolidation, which greatly improves the overall comfort and rehabilitation efficiency.

[0080] Technical features: wavelength selection, power matching and angle layout

[0081] The present invention mainly solves the problem of mutual interference between three infrared bands (near infrared IR-A, mid infrared IR-B, and far infrared IR-C) and achieves the best physical therapy effect.

[0082] Wavelength selection and feature matching

[0083] According to the leg physiotherapy needs of the elderly, near infrared (0.7–1.4μm), mid infrared (1.4–3.0μm) and far infrared (3.0–14μm) are selected as the core working bands, which are responsible for deep activation, middle-layer gentle conditioning and surface soothing health care respectively.

[0084] In the selection of lamps or heating elements, due to the differences in material processes (halogen lamps, carbon fiber tubes, ceramic heating plates, etc.), the equipment needs to work in a relatively high-humidity and high-temperature environment (such as a physiotherapy barrel with steam fumigation function), and has high requirements for waterproofing and moisture-proofing, so we choose ceramic heating plate materials. Additional waterproof sealing measures (package cover, sealing ring, etc.) are also taken in the design to further enhance safety and reliability. Ensure that the main peak emission range of each band is consistent with the design target to avoid excessive wavelength deviation or useless spectral interference in production.

[0085] Power matching and segmented control

[0086] Taking into account the different penetration depths and thermal effects of the three bands, each group of infrared lights is divided into independent power channels in the hardware circuit design to facilitate segmented control or synchronous adjustment on the software side.

[0087] A higher power density is set for the near-infrared lamp group to meet the needs of rapid warming and deep therapy; the mid-infrared and far-infrared lamp groups are mainly medium and low power, focusing on maintaining a mild and stable thermal environment.

[0088] Through pulse width modulation (PWM) or constant current drive, the power output of each lamp group is automatically adjusted according to the user's body sensation and the feedback from the temperature / light intensity sensor in the device, ensuring that the deep and surface layers can obtain appropriate heat supply at different stages.

[0089] Light source angle layout and distance control

[0090] Spatial partition layout: Inside the barrel or in the three-dimensional structure, the near-infrared lamp group is arranged at the key parts closer to the user's joints or muscles, and the light is projected more directly to the deep target area through the appropriate inclination angle; at the same time, the mid-infrared and far-infrared lamp groups are arranged in relatively peripheral or upper positions to form surround heating to prevent the near-infrared and other band lamp groups from strongly overlapping at the same position.

[0091] Optical auxiliary components: In order to reduce the mutual interference of light between bands, a reflective cover or optical lens is installed on the near-infrared lamp group to focus or limit the radiation range; the mid- and far-infrared lamp groups adopt a diffuse reflection or surface divergence design to evenly distribute the energy on the leg surface.

[0092] Lamp group distance and heat dissipation management: According to the heat generation and heat dissipation characteristics of each infrared lamp, the distance from the lamp surface to the skin is reasonably set to avoid local overheating caused by near-infrared lamps being too close; at the same time, a heat dissipation channel or insulation layer is reserved for each lamp group so that they can independently control the temperature when working in parallel, reducing the risk of attenuation or overshoot caused by heat accumulation.

[0093] The effect of complementarity and avoiding interference

[0094] Through band differentiation + power partitioning + angle differentiation, this design can focus near-infrared for deep activation without excessively affecting the gentle physical therapy of the surface and middle layers by mid- and far-infrared;

[0095] The radiation center areas of different lamp groups are "misaligned" to avoid energy superposition in the same small area causing burns or scorching, and to prevent unnecessary spectrum overlap between each other and weakening the therapeutic effect;

[0096] Combined with intelligent software algorithms, the device can activate each light group simultaneously or in stages, and on the basis of complementarity, achieve full-process optimized physical therapy of "rapid preheating + gentle maintenance + surface relief" for the elderly's legs, significantly enhancing the synergistic value of multi-band infrared.

[0097] Application effect: layered therapy and compatibility

[0098] The present invention combines three wavebands, namely near infrared (IR-A), mid infrared (IR-B) and far infrared (IR-C), in the same device, giving full play to their differentiated advantages in deep and surface therapy, and realizing multi-level comprehensive conditioning of common leg diseases in the elderly (such as arthritis, muscle soreness, poor microcirculation, etc.).

[0099] Near Infrared (IR-A): Rapid Relief of Deep Joint and Muscle Pain

[0100] Near-infrared has a shorter wavelength and stronger penetrating power, and can directly reach joints, ligaments and deep muscles.

[0101] It is particularly suitable for deep heat therapy of the knee joints and leg muscles of the elderly, and can quickly relieve the soreness and stiffness caused by degenerative arthritis, fasciitis, etc.

[0102] Using near-infrared for "quick preheating" can significantly accelerate local blood circulation, activate muscle activity, and make deep preparations for subsequent medium and far-infrared therapy or massage.

[0103] Mid-infrared (IR-B): Gradual heating and temperature connection

[0104] The mid-infrared band mainly acts on the skin and superficial muscles, and can form a continuous thermal effect within a milder temperature range.

[0105] After the deep tissue has been activated by near-infrared, mid-infrared can "take over" the therapy process, steadily maintain the temperature and avoid sudden temperature changes, making it easier for the elderly to adapt to long-term therapy.

[0106] When combined with fumigation or medicinal bath functions, mid-infrared can effectively promote the penetration of medicinal liquids and the opening of pores, reduce irritation, and at the same time play a soothing and relaxing role.

[0107] Far infrared (IR-C): Steady-state heating for soothing and health care

[0108] Far infrared radiation is mild and penetrates shallowly, but it can provide continuous and uniform heat to the skin and superficial blood vessels, accelerate microcirculation and help the body sweat and detoxify.

[0109] Especially suitable for relaxation and conditioning in the "finishing stage": after the near and medium infrared have completed the deep and middle layer heat therapy, the gentle radiation of far infrared can stably maintain the therapeutic temperature, so that the legs can get full relief and health care.

[0110] For the elderly with rheumatism, cold constitution or poor blood circulation, the continuous warmth of far-infrared can significantly improve symptoms such as cold limbs and difficulty in movement.

[0111] Comprehensive solution capability: compatible with various geriatric diseases and stage needs

[0112] Arthritis and muscle soreness: Near infrared deeply relieves pain + mid-infrared and far-infrared continuously maintain temperature, promote blood circulation, and help relieve joint inflammation and muscle fatigue.

[0113] Microcirculation disorders: The three bands promote vasodilation and blood flow at different levels, which can synergistically improve blood circulation in the lower limbs and reduce edema and swelling.

[0114] Flexible combination and personalized application: The device can choose to turn on the three-band light source in different time periods or superimpose it in parallel at the software level, providing customized physiotherapy mode for the different physical conditions and disease course needs of the elderly.

[0115] Safety Warning

[0116] Temperature and infrared light intensity / radiation integrated management function

[0117] By combining temperature detection with infrared radiation intensity detection, the multifunctional leg infrared therapy fumigation massage barrel has significantly enhanced both safety and therapeutic effects, thus providing elderly users with a more comfortable, efficient and controllable comprehensive therapy experience.

[0118] 1. Functional Overview

[0119] During the treatment, the temperature inside the barrel and on the skin surface of the legs is monitored, while the infrared lamp radiation intensity (or light intensity) is detected in real time. Based on the dynamic data of the two, the safety and comfort of the current treatment environment are comprehensively analyzed. The system uses intelligent algorithms to adjust the infrared lamp power output and working time to avoid overheating, burns or excessive radiation.

[0120] 2. Key implementation mechanisms

[0121] Multi-point temperature sensor layout

[0122] Temperature sensors are installed on the barrel wall, sole plate and near the infrared light source.

[0123] Each sensor transmits temperature data to the main control system. The main control software determines whether the local or overall ambient temperature exceeds the limit by analyzing the temperature difference and heating rate of each point.

[0124] Infrared radiation / light intensity sensor monitoring

[0125] Install a light intensity detector at or near the infrared lamp group to detect the actual infrared radiation output.

[0126] If the light intensity exceeds the safety threshold (such as an abnormality in the infrared light or too high power), the system will immediately sound an alarm and implement power reduction or shutdown measures.

[0127] Intelligent control algorithm integration

[0128] Use PID or adaptive algorithm to simultaneously receive "temperature" and "infrared light intensity" data.

[0129] When the temperature is close to the upper limit set by the user and the light intensity is still high, the system will reduce the power of the infrared lamp in advance to avoid rapid temperature overshoot; if the temperature is low but the light intensity is normal, the system can increase the power appropriately to speed up the heating speed.

[0130] Linked protection and graded warning

[0131] Level 1 warning: When the temperature or radiation intensity reaches the "moderate" warning line, the system will send a buzzer or screen prompt to the user, suggesting that the treatment time be shortened or the power be reduced appropriately.

[0132] Secondary protection: When the temperature or radiation intensity continues to rise to the "high-risk" threshold, the system automatically stops the infrared light and starts a forced cooling program, while issuing a high-level alarm (such as voice prompts or power cuts) to prevent burns or worsening equipment failures.

[0133] 3. Functional value and significance

[0134] Dual monitoring, security upgrade

[0135] There are blind spots in relying solely on temperature or light intensity monitoring, but the combination of the two can identify unexpected conditions of equipment or environment (such as abnormal overheating of a single light group, sensor failure, etc.) in real time, achieving more precise safety control.

[0136] Comfort and efficacy are equally important

[0137] Reduce treatment interruptions caused by excessive temperature fluctuations or "sudden power reduction", and keep the entire treatment process within the optimal temperature and radiation intensity range to ensure a smooth experience and stable therapeutic effect.

[0138] Intelligence and scalability

[0139] Combined with subsequent cloud data analysis or health monitoring systems (such as detecting the user's heart rate, blood pressure, etc.), the accuracy of personalized physiotherapy plans can be further improved and maintenance costs can be reduced.

[0140] Deep integration design

[0141] Composite function: steam fumigation + multi-band infrared + massage

[0142] The present invention cleverly combines the steam generator, three-band infrared light source, and massage module (airbag / roller, etc.) in a compact and efficient manner in the same therapy barrel to form a multi-dimensional therapy solution. Through reasonable spatial layout and intelligent control methods, it overcomes the common problems of "insufficient space utilization", "difficult to unify the temperature environment", and "large interference when functions are superimposed" in traditional single-function products. It not only makes full use of space and unifies the hot and humid environment, but also reduces the interference between functional modules, improves collaborative efficiency and user experience, and is especially suitable for daily care and therapy for elderly people with mobility problems.

[0143] Multifunctional integration of structural design

[0144] Reasonable separation of steam generation device and infrared light source:

[0145] A steam generating module is arranged at the bottom or side wall of the barrel and is relatively isolated from the infrared lamp group by a high-temperature resistant and waterproof barrier, which not only ensures the unobstructed flow of the steam nozzles, but also avoids direct impact of the steam on the lamp source or electrical safety hazards.

[0146] The three-band infrared light sources (near infrared, mid infrared, and far infrared) are distributed at different positions in the barrel according to deep and surface needs, forming a three-dimensional therapeutic light field.

[0147] Differentiated layout of massage modules:

[0148] Diverse selection of components:

[0149] If you choose a roller massage unit, place an embedded roller on the sole of the foot or calf, and set up a large gap for drainage or ventilation;

[0150] If you choose an airbag massage assembly, reserve space around the barrel wall to accommodate the airbag assembly and its air path layout to ensure that the inflation / deflation action is not affected by steam humidity.

[0151] Integrated sealing and exhaust design:

[0152] The whole inner layer is packaged with moisture-resistant and heat-proof materials (such as polymer composite or stainless steel liner), and exhaust holes are reserved on the top or barrel wall to allow steam to circulate smoothly and be evenly distributed throughout the treatment space.

[0153] Unified coordination of temperature environment and humidity environment

[0154] Step temperature control:

[0155] First, use near infrared to quickly heat up, then use mid-infrared or far-infrared to maintain a stable temperature, and turn on the steam generator at the same time to allow the legs to relax deeply in a hot and humid environment;

[0156] When the system detects that the temperature or humidity exceeds the threshold, it can automatically adjust the infrared lamp power or steam output to ensure that the environment remains within the therapeutic range acceptable to the elderly.

[0157] Partition and time scheduling:

[0158] The steam session can be performed alternately or in parallel with the massage session: first, the steam session opens the pores, then the massage session dredges the muscles and speeds up blood circulation;

[0159] Based on the data from the real-time temperature and humidity sensors in the barrel, the main control system will intelligently switch to the appropriate working mode to avoid poor therapy effects due to excessively high or low temperatures.

[0160] Interference suppression and synergy enhancement when functions are superimposed

[0161] Hierarchical structure prevents mutual interference:

[0162] The infrared lamp group, steam pipeline and massage mechanism are supported independently of each other. The electrical system is separated from water vapor through heat insulation and moisture insulation design, which reduces the corrosion of water vapor to electrical components and prevents thermal radiation between high-temperature components from interfering with each other.

[0163] Integrated control algorithm:

[0164] The equipment's software system performs multi-channel control of infrared light, steam and massage, and plans the start and stop sequence, time period and intensity level of each function in advance;

[0165] By utilizing feedback from temperature, humidity, and light intensity sensors, the infrared power or steam output is dynamically adjusted, allowing the entire therapy process to remain safe and stable while multiple functions are running in parallel, achieving a synergistic effect.

[0166] The overall effectiveness of multi-dimensional physical therapy

[0167] Steam fumigation + infrared radiation:

[0168] Soften the epidermis and pores through fumigation, accelerate the penetration of mid-infrared / far-infrared heat into the subcutaneous tissue, and reduce the phenomenon of epidermal dryness and heat conduction obstruction in traditional physiotherapy equipment;

[0169] It helps to sweat and detoxify, improve microcirculation; if combined with herbal fumigation, it can enhance the effect of foot protection or joint health care.

[0170] Massage + Multi-band Infrared:

[0171] When the near-infrared is preheated first, the massage intensity is temporarily turned off or reduced to allow the heat to reach the muscles and joints directly;

[0172] During the far-infrared maintenance stage, the roller or airbag massage is activated to strengthen the relaxation of the leg muscles, accelerate waste metabolism and relieve fatigue.

[0173] Comfort and safety:

[0174] The multifunctional integration reduces the trouble of the elderly to repeatedly move or switch devices. At the same time, the intelligent safety monitoring system (temperature / humidity / light intensity sensors, etc.) is used to effectively ensure the safety of use.

[0175] Mutual promotion of steam fumigation and band thermal effect

[0176] In the multifunctional leg therapy device of the present invention, the combined application of steam fumigation and infrared bands can significantly improve the thermal effect conduction and drug penetration efficiency. Specifically, mid-infrared (IR-B) and far-infrared (IR-C) provide a gentle and uniform heat field during the fumigation stage, which promotes the gradual opening of pores and accelerates blood circulation on the surface of the skin, so that herbal liquid or care liquid can penetrate the subcutaneous tissue more effectively. Near-infrared (IR-A) can perform deep heating at a specific time period, quickly relieve muscle tension and joint pain, and form a synergistic physical therapy mode of deep and surface "inside and outside cooperation".

[0177] Synergistic Effect of Mid-IR / Far-IR and Steam

[0178] Gentle and uniform thermal field:

[0179] During the fumigation process, the temperature distribution in the therapy cavity is more balanced through the surface or surrounding irradiation of mid-infrared and far-infrared, avoiding local overheating caused by traditional single-point or high-power near-infrared.

[0180] Reasonably set the power and position of the infrared lamp group to allow the steam heat and infrared radiation to create a continuous and comfortable warm environment.

[0181] Promote pore opening and drug penetration:

[0182] The dual stimulation of temperature and humidity will speed up the opening of the sweat glands and pores of the skin, accelerating the absorption of care substances such as herbal ingredients, liquid medicine or essential oils;

[0183] At this time, the gentle thermal effect of mid- and far-infrared helps maintain a suitable but non-irritating temperature, making it easier for the elderly to accept long-term fumigation therapy.

[0184] Near infrared deep heating at specific time periods

[0185] Quickly relieve muscle tension:

[0186] When there is obvious soreness and stiffness in the deep joints or muscles of the legs, the near-infrared light group can be turned on in different time periods on the basis of mid-infrared and far-infrared fumigation to strengthen the irradiation of specific parts (such as knee joints and soles of the feet);

[0187] The strong penetrating power of near-infrared can increase local temperature faster, activate deep blood circulation, and accelerate the relief of muscle fatigue and tension.

[0188] Partial irradiation:

[0189] In key areas such as the soles of the feet, the duration or power of near-infrared light can be further enhanced; in the calves or other more sensitive parts, only medium and far-infrared warmth and fumigation are maintained to ensure overall temperature balance and comfort.

[0190] Specific implementation method: Physiotherapy application scenarios by stage or part

[0191] Phased mode:

[0192] Phase 1 (Near Infrared Deep Rapid Heating): Concentrated heat is transferred to joints and muscles in a short period of time to quickly relieve pain;

[0193] The second stage (mid-infrared / far-infrared + steam fumigation): Switch to mild and uniform mid-infrared and far-infrared, and start the steam generator to maintain a constant humid and hot environment for a longer period of time to help open the pores and promote the absorption of medicine or care media.

[0194] The third stage (surface health care consolidation): When the fumigation is about to end, continue to retain the far-infrared low-power irradiation to fully relax the elderly's legs and relieve possible secondary tension or stiffness.

[0195] Partial irradiation mode:

[0196] When there is heel pain or arthritis on the sole of the foot, the near-infrared radiation can be increased in a targeted manner; if the skin on the calf is more sensitive, maintain a warm fumigation mode dominated by medium and far infrared to avoid local overheating stimulation.

[0197] Through multiple independent channels or sensors in the barrel, differentiated control of infrared lamp power and steam distribution in different areas can be achieved, forming a flexible and personalized therapy plan.

[0198] Leg Massage Integration and Control

[0199] The multifunctional leg therapy device of the present invention is not only equipped with near-infrared, mid-infrared and far-infrared three-band light sources and a steam fumigation system, but also cleverly integrates massage modules (roller type or airbag type) to form a multiple therapy plan for the leg muscles and joints of the elderly. Especially when the far-infrared surface therapy stage is combined with the massage function, the comfort and therapy efficiency can be greatly improved.

[0200] The synergistic effect of far infrared and massage

[0201] Surface warmth and muscle relaxation:

[0202] Far infrared (IR-C) provides gentle and stable heat radiation in the later stage of equipment use or during surface care period, allowing the leg skin and superficial muscles to relax.

[0203] At this time, turning on the massage function (such as roller massage or air bag massage) can further help relax muscles, expel metabolic waste, and relieve fatigue and soreness.

[0204] Lowering the pain threshold:

[0205] Through far-infrared heat compress, the skin and surface nerves are more easily adapted to external stimulation, avoiding discomfort caused by excessive massage force or low ambient temperature;

[0206] The combination of thermal effect and mechanical stimulation can accelerate blood circulation and promote lymphatic return, which is especially beneficial for elderly legs with edema or poor microcirculation.

[0207] Flexible scheduling of synchronous or asynchronous control

[0208] Software linkage strategy:

[0209] The main control system of the device can coordinate the start and stop and power level of the far-infrared lamp group and massage module according to the real-time feedback of the temperature sensor and massage force sensor (such as air pressure and roller speed);

[0210] In "synchronous mode", far infrared and massage are turned on at the same time, allowing the elderly to receive massage in a warm and soothing environment; in "asynchronous mode", near infrared or mid-infrared deep therapy can be performed first, and then the massage function can be enabled while switching to far infrared continuous heating.

[0211] Customized Therapy Programs:

[0212] Users can pre-set the duration, light power, and massage intensity of different stages; the equipment automatically executes in sequence, thereby customizing a personalized therapy process (such as "deep warming → steam fumigation → far-infrared massage relaxation → end of warmth preservation").

[0213] Comprehensive benefits and technical advantages

[0214] Efficient relaxation and fatigue management: Far-infrared warmth can improve superficial circulation; combined with the deep or local kneading effect of massage, it forms a dual effect of warm therapy and mechanical stimulation.

[0215] Safety and personalization are equally important: multiple sensors and intelligent algorithms are used to achieve real-time monitoring of far-infrared temperature and dynamic control of massage intensity, which reduces the risk of burns or overstimulation for the elderly while ensuring the therapeutic effect;

[0216] Simplified equipment operation: The integrated interactive design eliminates the tedious steps brought by the traditional equipment of "a thermal therapy device + a massage machine + manual scheduling", which is more in line with the "labor-saving and worry-free" usage requirements of elderly users.

[0217] Composite therapy and segmented control mechanism of multi-band light source

[0218] The present invention realizes dynamic switching and orderly connection of three infrared bands at the hardware and software levels through precise control of time periods and power divisions, greatly improving the comprehensive improvement ability of leg physiotherapy on deep joints, muscles and even superficial blood circulation. This multi-band complex physiotherapy mode based on "process-based" design completely gets rid of the limitations of simple band superposition or single-band continuous emission in the past, and provides a more efficient and safer solution for the daily rehabilitation and health care of the elderly.

[0219] Not just simple superposition, but "precise segmentation" and "dynamic switching"

[0220] If traditional or ordinary physical therapy equipment is equipped with multiple infrared bands, it often only performs simple functional stacking, that is, multi-band lamps are installed at the same time but it is impossible to perform fine timing control and power adjustment of each band during the physical therapy process.

[0221] The present invention emphasizes the start and stop of the three bands of near infrared (IR-A), mid infrared (IR-B) and far infrared (IR-C), especially the power adjustment in different physical therapy stages (such as preheating, fumigation, massage) or different temperature / humidity environments. The software pre-adjustment strategy realizes the real precise control of time period / power.

[0222] Through the dynamic switching strategy of software and hardware linkage, the device can automatically switch the corresponding band or adjust its power output after detecting changes in temperature, humidity or leg status. Different from the simple design on the market that usually only adopts "all on / all off" or "single switch" control, it truly achieves "process-based" management of infrared energy.

[0223] Principle of multi-band layered therapy

[0224] The present invention is not limited to "far-infrared surface hot compress" in terms of physical therapy concept, but uses near-infrared for deep activation of joints and muscle groups, medium-infrared for middle-layer or gradual heating, and far-infrared for continuous shallow surface warmth and relief.

[0225] This layered application of "deep activation first, then surface warming" can not only meet the needs of the elderly for various diseases such as leg arthritis, rheumatism, muscle soreness, etc., but also take into account comfort and safety.

[0226] In the patent, the technical recognition of this solution can be highlighted: traditional single-band devices or devices that only focus on far-infrared surface thermal therapy are difficult to meet deep physical therapy needs, while the present invention highly matches the characteristics of near, medium and far infrared to different depths of leg tissues, forming a physical therapy system with deep, medium and shallow triple effects, showing an innovative path that is completely different from the existing technology.

[0227] Nonlinear coupling design with fumigation and massage functions

[0228] Timing control of "mutual promotion" between infrared and fumigation

[0229] Limitations of traditional solutions:

[0230] Most existing products only enable steam or infrared preheating separately first, and then simply add them together, lacking coordinated regulation in the three dimensions of "temperature (T) - humidity (H) - light band (λ)".

[0231] The multi-parameter coordinated control of the present invention:

[0232] When mid-infrared (IR-B) or far-infrared (IR-C) is selected as the main heat source in the fumigation stage, the system will dynamically adjust the power output of the infrared lamp source according to the real-time changes in the amount of steam, humidity and temperature in the barrel;

[0233] Through this flexible adjustment, steam can play a more effective role in the "appropriate temperature zone", promote the opening of pores and allow the liquid medicine or herbal ingredients to quickly penetrate the subcutaneous tissue;

[0234] If the temperature, humidity or light intensity sensor detects that the temperature is about to exceed the limit (or the humidity is too high), the system can actively reduce the infrared intensity or temporarily shut down the steam generator to prevent overheating, stuffiness and other uncomfortable situations in time.

[0235] Technical effects and innovations:

[0236] The timing control of multi-parameter (T, H, λ) coupling is not just "sequential" or "simple superposition", but combines the multiple needs of leg therapy for the elderly for moist heat and light bands to make corresponding power and timing allocation in real time;

[0237] This idea of ​​deep-level linkage control is not common in traditional steam or infrared single-function equipment, and can provide a more stable and efficient therapy environment.

[0238] Combination of massage rhythm and band thermal effect

[0239] Pre-application of near infrared deep thermal effect:

[0240] Since near infrared (IR-A) has strong penetrating power on muscle and joint tissues, the present invention can start the near infrared lamp group in the key time period before the massage starts, so as to quickly heat up to the target temperature of the "deeper layer";

[0241] This can make the deep tissues of the elderly more relaxed, lay a good foundation for subsequent mechanical stimulation (roller or air bag massage), and reduce pain or poor effects caused by muscle tension.

[0242] Massage connection between steam process and far infrared heat preservation stage:

[0243] During the mid-infrared / far-infrared and steam fumigation stages, if the deep temperature has been reached, the system can switch to the "massage and soothing" program, using the gentle heat preservation characteristics of far-infrared to create a stable, moist and warm environment for massage;

[0244] The temperature fluctuations during this stage are relatively stable, which can effectively relieve muscle soreness and help blood circulation and fatigue metabolism.

[0245] Innovation of multi-dimensional and step-by-step therapy rhythm:

[0246] The present invention combines the three processes of "near infrared deep penetration - steam fumigation / far infrared continuous heat preservation - massage and soothing" in sequence or cross-combination;

[0247] This multi-dimensional, step-by-step physical therapy approach requires comprehensive consideration of the elderly's joint mobility, blood circulation characteristics, heat tolerance, and muscle adaptability in different temperature and humidity environments, and is therefore obviously non-obvious.

[0248] Compared with the simple combination of "pure infrared + pure massage" of traditional equipment, the present invention achieves more detailed "process management" in terms of how to allocate infrared band output, steam volume, and when to intervene in massage, thereby significantly improving the therapeutic effect and comfort of use.

[0249] Complexity of multifunctional integration and spatial coupling design

[0250] The present invention demonstrates a high level of innovative complexity in terms of multifunctional integration and spatial coupling design. Through clever component layout, isolation protection, and robust electrical and structural design, it not only greatly improves the coupling and safety of three-band infrared, steam, and massage functions in the same device, but also provides a more convenient and efficient product solution for multi-dimensional physical therapy for the elderly.

[0251] Realize three-band light source + steam system + massage mechanism in a limited space

[0252] Traditional products have single functional limitations:

[0253] The foot baths or leg therapy tubs on the market are usually only equipped with simple heating devices or single infrared lamps, or when the functions are superimposed, they are limited to a certain infrared band and massage combination, lacking systematic and multifunctional structural planning.

[0254] The high-density functional integration of the present invention:

[0255] The same barrel must contain three-band infrared light sources (near infrared, mid-infrared, and far infrared), a steam generator, and a massage mechanism (roller / airbag), which places strict requirements on the size of the equipment, component layout, and wiring arrangement.

[0256] Within the limited internal volume, it is necessary to reasonably allocate the light source angle and installation position, design the direction of the steam pipe to ensure even distribution of heat and humidity, and reserve enough space to accommodate the mechanical structure and moving parts of the massage components.

[0257] Comprehensive consideration of heat dissipation, moisture resistance and ergonomics:

[0258] There is an overlap and conflict between the heat dissipation requirements of the three-band infrared lamp and the heat dissipation and waterproofing requirements of the steam generator;

[0259] When users put their legs in, they need to comply with ergonomic and safety distance requirements to prevent their legs and feet from directly touching high-temperature light sources or mechanical rotating parts;

[0260] This type of multi-faceted structural design often goes beyond the intuition of conventional technicians and requires multi-dimensional professional planning such as spatial coupling, partition insulation, waterproofing and moisture-proofing.

[0261] Mutual Interference Suppression and Linkage Gain

[0262] Challenges of coexistence of multiple heating elements, steam and electronic sensors:

[0263] The near-infrared lamp has a high operating temperature, the steam environment has a very high humidity, and it also needs to power the massage motor or airbag drive module at the same time;

[0264] Inside the small device, multiple heat sources, humidity sources and electronic signals are superimposed on each other, which greatly increases the probability of interference and failure, making it difficult to simply copy or transplant ordinary heating equipment into this multi-functional scenario.

[0265] Core technical means: isolation layer, electromagnetic compatibility design and independent drive circuit:

[0266] By adding an isolation layer or protective cover in the key area of ​​the barrel, the infrared lamp group is separated from the steam pipeline to ensure that the circuit board and the drive module are protected from water vapor erosion;

[0267] Adopt electromagnetic compatibility (EMC) design to reduce electromagnetic interference generated when infrared light is switched or massage motor is working, and shield or filter the sensor and control circuit;

[0268] Different functional modules use independent drive circuits or separate channels for power supply to avoid mutual influence caused by instantaneous current fluctuations or overloads, thus enhancing the stability of the overall equipment operation.

[0269] Multi-point exhaust and moisture-proof measures:

[0270] For steam output and circulation, multiple exhaust or ventilation channels are reserved, and high temperature resistant and waterproof materials are used to seal the connectors and pipelines;

[0271] Infrared lamps and motor components can be equipped with a casing or package with a higher waterproof grade to ensure long-term stable operation in high temperature and high humidity environments.

[0272] A feasible and stable productization solution:

[0273] The present invention implements refined structural design and electrical isolation of the three-band infrared, steam, massage and other functions in a limited space, and uses a variety of safety assurance and anti-interference measures to enable each function to cooperate with each other and work smoothly in high humidity and high temperature scenarios;

[0274] This not only significantly improves the comprehensive therapeutic effect of the equipment, but also ensures that no serious safety issues will occur during long-term, multi-mode use, achieving a commercially viable level of reliability.
