Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent wearable devices, and in particular relates to intelligent slimming underwear and an intelligent control method thereof. Background Art

[0002] Although there are various slimming bras and technologies on the market, they generally have problems such as lack of targeting, single function or poor comfort. Traditional physical slimming bras mostly use a fixed pressure structure to achieve body shaping through single mechanical compression. Usually, slimming bras only apply constant pressure to local parts of the body through elastic fabrics, and cannot dynamically adjust the pressure according to the degree of fat accumulation in different parts of the body. As a result, there is insufficient pressure in fat-rich areas such as the abdomen and thighs, while sensitive areas such as the shoulders feel uncomfortable due to excessive pressure. This type of product does not incorporate the theory of human acupuncture points and relies only on physical squeezing. The slimming effect is limited to short-term body shaping, and it is difficult to achieve deep fat metabolism.

[0003] While some slimming bras with heating functions incorporate far-infrared materials, they often use a fixed-fit design, securing the far-infrared fibers to the interlayer through sewing. Due to the lack of a dynamic fit mechanism, the material maintains loose contact with the skin, resulting in inefficient far-infrared release. This is particularly true during exercise or changes in body position, as heat conduction is unstable and cannot consistently and effectively affect fat cells. Furthermore, existing products generally lack intelligent control logic, relying on manual pressure adjustment, such as adjusting the tightness of Velcro, which fails to achieve closed-loop pressure feedback. This can easily lead to excessive pressure due to user error or individual differences, posing a safety hazard.

[0004] In the field of acupoint massage, traditional weight loss equipment is mostly external massagers that require users to operate them by hand. They have poor portability and cannot be combined with daily wear. They usually need to be worn independently on specific parts of the body. The usage scenarios are limited and it is difficult to integrate them into daily clothing to achieve continuous intervention.

[0005] To this end, those skilled in the art have proposed an intelligent slimming underwear and an intelligent control method thereof, which aims to dynamically adjust pressure, combine acupoint stimulation with far-infrared metabolic acceleration, and have intelligent safety control to effectively improve the weight loss effect. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides an intelligent slimming underwear and an intelligent control method thereof to solve the problems raised in the background technology.

[0007] According to a first aspect of the present disclosure, a smart slimming underwear is proposed, comprising: a top and a bottom; both the top and the bottom are provided with a self-pressurizing component;

[0008] The self-pressurizing component includes a first micro air pump arranged at the lower end of one side of the outer surface of the upper garment, a main air guide path is fixedly installed at the output end of the first micro air pump, a micro solenoid valve input end is fixedly installed at the end of the main air guide path, a micro solenoid valve output end is fixedly installed at the air guide branch, a flexible air bag is fixedly installed at the end of the air guide branch, a pressure sensor is installed in the flexible air bag, a partition is fixedly installed on the side of the flexible air bag close to the skin, and bumps are fixedly provided on the other side of the partition according to acupuncture points, and a second micro air pump is installed at the upper end of one side of the outer surface of the lower garment.

[0009] Preferably, the top and bottom garments are both provided with two layers of pure cotton fabric, with far-infrared emitting material added to the middle layer.

[0010] Preferably, the flexible airbags in the self-pressurizing assembly are respectively arranged at the fat accumulation parts of the upper and lower garments, and the fat accumulation parts include the upper limbs above the elbow joints, the abdomen, the thighs, and the buttocks; the shape of the flexible airbags fits the curve of the human body.

[0011] Preferably, the micro solenoid valve is used to control the inflation and deflation of each flexible airbag to adjust the pressure; the first micro air pump is used to inflate the flexible airbag in the upper garment, and the second micro air pump is used to inflate the flexible airbag in the lower garment.

[0012] Preferably, the convex block is made of graphene and is coated in soft silicone; when the flexible airbag expands, the convex block presses on the corresponding acupoints, which include: the acupoints above the elbow joint of the upper limb are Quchi, Shousanli, and Bihuang; the acupoints on the abdomen are Zhongwan, Tianshu, Guanyuan, Qihai, Daheng, and Daimai; the acupoints on the thigh are Fengshi, Xuehai, and Futu; the acupoints on the buttocks are Huantiao, Zhibian, and Chengfu.

[0013] According to a second aspect of the present disclosure, a smart control method for smart slimming underwear is proposed, which is applied in the first aspect and includes the following steps:

[0014] S1. Obtaining a user-set target pressure value, pressurization area selection, and pressurization duration through wireless terminals installed on the outer periphery of the upper and lower garments; the pressurization area includes at least one of the upper limbs above the elbow joint, abdomen, thigh, and buttocks;

[0015] S2. Activate the micro air pumps and micro solenoid valves in the corresponding zones according to the selected pressurized zones; the upper garment zone is supplied with air by the first micro air pump, and the lower garment zone is supplied with air by the second micro air pump;

[0016] S3. Inflate the target flexible airbag through a micro air pump. The pressure sensor monitors the actual pressure value in the airbag in real time, compares the actual pressure value with the target pressure value, and dynamically adjusts the opening of the micro solenoid valve and the air pump power through the PID algorithm. When the actual pressure value reaches the target pressure value and remains stable, the constant pressure maintenance stage is entered;

[0017] S4. During the expansion of the flexible airbag, the graphene bump is synchronously triggered to press the corresponding acupuncture point;

[0018] S5. During the pressurization process, the far-infrared emitting material in the interlayer continuously releases far-infrared rays;

[0019] S6. When the set pressurization time is reached, or the pressure sensor detects that the pressure exceeds the threshold, the micro air pump is turned off and the micro solenoid valve is opened for exhaust.

[0020] Preferably, in step S1, the pressurization duration is divided into multiple cycles, and the inflation and pressurization stage and the exhaust and relaxation stage are performed alternately in each cycle. The ratio of the inflation and pressurization stage duration to the exhaust and relaxation stage duration ranges from 1:1 to 3:1.

[0021] Preferably, in step S3, when the sampling period is T and the kth sampling is performed, the error e(k) is calculated by comparing the actual pressure value with the target pressure value using the following formula:

[0022] e(k)=P t -P a (k)

[0023] Among them, P t The target pressure value set by the user, P a (k) is the actual pressure value fed back by the pressure sensor;

[0024] The micro solenoid valve opening and air pump power are dynamically adjusted through the PID algorithm. The PID output is:

[0025]

[0026] Among them, K p , K i , K d are proportional, integral and differential coefficients respectively, and u(k) is the control output; the control output u(k) is decomposed into the coordinated control of the air pump power and the solenoid valve opening, so that the air pump and the solenoid valve complement each other, that is, the solenoid valve is closed during inflation and opened during decompression;

[0027] The constant pressure holding stage begins when the following conditions are met:

[0028] and max i∈[k-N+1,k] P a(i)-min i∈[k-N+1,k] P a (i)≤ε

[0029] Where δ represents the allowable average error threshold, ε represents the allowable pressure fluctuation threshold, and N is the continuous sampling window size.

[0030] Preferably, the pressing depth of the graphene bump is controlled by establishing an airbag pressure-bump displacement mapping relationship table, and adjusting the target pressure value to indirectly control the depth of the bump sinking into the skin. The depth control range is 1-3mm, and the corresponding pressure value is 30%-70% of the target pressure value of the partition.

[0031] According to the airbag pressure-bump displacement mapping relationship table, a piecewise linear mapping function is established, which is expressed as:

[0032]

[0033] Among them, d min is the minimum effective depth of the linear working area, which is 1mm. max is the maximum displacement value of the saturation zone, which is 3 mm. k1 is the linear coefficient of the initial elastic zone. P1 is the pressure limit threshold for entering the linear working zone. k2 is the slope of the linear working zone. P2 is the pressure limit threshold for entering the saturation zone.

[0034] According to different pressurization areas, use the following formula to obtain the actual control target pressure value:

[0035] P c =min(max(P t ,0.3P t ),0.7P t )

[0036] Among them, P t The target pressure value set by the user, P c is the target pressure value for actual control.

[0037] Preferably, in step S5, the flexible airbag is pressurized so that the far-infrared emitting material fits the human skin and absorbs the body's heat. The human body temperature excites the far-infrared emitting material to continuously release far-infrared rays with a wavelength of 4-14 microns, thereby increasing the temperature of fat cells and accelerating fat metabolism.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. The present invention stimulates fat accumulation areas through pressure application, combined with acupoint massage and far-infrared hot compress, to achieve synergistic effects from three dimensions: mechanical compression, meridian regulation, and metabolic acceleration, thereby improving weight loss effects. Pressure closed-loop control is achieved through pressure sensors and PID algorithms, improving pressure control accuracy and enabling personalized pressure settings based on the needs of different areas.

[0040] 2. The present invention applies pressure to specific fat accumulation areas through flexible airbags, thereby preventing the whole body from being pressurized and affecting normal activities, while reducing interference with non-target areas.

[0041] 3. The present invention divides the pressurization time into multiple cycles. The ratio of the inflation and exhaust phases in each cycle is adjustable, simulating the massage rhythm, avoiding discomfort caused by long-term continuous pressurization, and enhancing the effect at the same time. It also has a pressure over-limit protection mechanism, that is, the pressure sensor detects the over-limit threshold and exhausts air, avoiding excessive pressure due to equipment failure or user misoperation, and ensuring safe use.

DETAILED DESCRIPTION

[0047] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0048] Example 1: As shown in the attached Figure 1 To the attached Figure 2 As shown, the present invention provides an intelligent slimming underwear, including: a top 100 and a bottom 200; the top 100 and the bottom 200 are both provided with a self-pressurizing component 300; according to different obesity types and individual differences, different sizes, pressure values, and pressurization time combinations can be selected to achieve personalized weight loss treatment plans, which has broad application prospects and market potential.

[0049] The self-pressurizing component 300 includes a first micro air pump 301 arranged at the lower end of one side of the outer surface of the upper garment 100, the output end of the first micro air pump 301 is fixedly installed with an air guide main path 302, the end of the air guide main path 302 is fixedly installed with an input end of a micro solenoid valve 303, the output end of the micro solenoid valve 303 is fixedly installed with an air guide branch 304, the end of the air guide branch 304 is fixedly installed with a flexible air bag 305, a pressure sensor 306 is installed in the flexible air bag 305, the flexible air bag 305 is fixedly installed with an interlayer 307 on the side close to the skin, and the other side of the interlayer 307 is fixedly provided with bumps 308 according to the acupoints, and a second micro air pump 309 is installed at the upper end of one side of the outer surface of the lower garment 200.

[0050] The first micro air pump 301 and the second micro air pump 309 are used to inflate the flexible airbag 305 by inflating air, thereby applying pressure to specific areas and providing the power for acupoint pressing and far-infrared therapy. The main air guide 302 and the branch air guide 304 are used to transmit gas, connecting the first micro air pump 301 and the second micro air pump 309 with the flexible airbag 305 to ensure stable gas delivery and a smooth pressurization process. The micro solenoid valve 303 is used to control the inflation and deflation of the flexible airbag 305, adjusting the pressure so that the pressure can accurately reach the user-set value and remain stable.

[0051] The pressure value is set according to the amount of body fat. The pressure gradually decreases from the calf to the thigh and buttocks to prevent water and blood metabolism disorders or edema. Through this pressure difference, the fat is guided to move in a specific direction and redistributed to achieve the effect of shaping and reducing local fat accumulation, visually improving the body lines. Long-term wearing also helps the rational distribution and metabolism of fat.

[0052] The top 100 and the bottom 200 are both provided with two layers of pure cotton fabric, with far-infrared emitting material added to the middle layer. The thermal effect of far-infrared rays can accelerate the metabolism of fat cells and decompose triglycerides in fat cells into free fatty acids and glycerol.

[0053] The flexible airbags 305 in the self-pressurizing assembly 300 are positioned at fat-accumulating areas on the upper garment 100 and lower garment 200, providing targeted pressure. These areas include the upper limbs above the elbow joint (A1), the abdomen (A2), the thighs (A3), and the buttocks (A4). The flexible airbags 305 conform to the body's curves and feature a built-in pressure sensor 306, which monitors the pressure within the airbag in real time and provides data support for pressure regulation. The pressure sensor 306 provides real-time feedback on the actual pressure within the airbag, enabling dynamic adjustment of the air pump power and solenoid valve opening using a PID algorithm to ensure accurate pressure control.

[0054] The micro solenoid valve 303 is used to control the inflation and deflation of each flexible airbag 305 and to adjust the pressure; the first micro air pump 301 is used to inflate the flexible airbag 305 in the top 100, and the second micro air pump 309 is used to inflate the flexible airbag 305 in the bottom 200.

[0055] The bump 308 is made of graphene coated in silicone. When the flexible airbag 305 expands, the bump 308 presses on the corresponding acupuncture points, including: the acupuncture points A1 above the elbow joint of the upper limb are Quchi, Shousanli, and Bihuang; the acupuncture points A2 on the abdomen are Zhongwan, Tianshu, Guanyuan, Qihai, Daheng, and Daimai; the acupuncture points A3 on the thigh are Fengshi, Xuehai, and Futu; the acupuncture points A4 on the buttocks are Huantiao, Zhibian, and Chengfu. Combined with the characteristics of graphene, the acupuncture point stimulation effect is enhanced, promoting meridian dredging and metabolism.

[0056] Existing slimming bras often use physical compression or heating. This invention combines modern intelligent control technology with traditional Chinese medicine acupuncture theory by applying pressure through a flexible airbag 305, which in turn activates graphene bumps 308 to pressurize acupoints. Furthermore, independent air pumps, namely a first micro-pump 301 and a second micro-pump 309, are provided in the upper garment 100 and lower garment 200, respectively. This allows for independent pressure control of the upper and lower body regions, which is more precise than single air pump control and can provide differentiated pressure tailored to the characteristics of fat in different areas. The bumps 308 are made of graphene-coated silicone. Graphene has excellent thermal conductivity and biocompatibility, enhancing the conduction of acupoint stimulation. The softness of silicone ensures comfortable pressing, combining functionality and comfort compared to traditional massage particles. Existing far-infrared materials in underwear are often fixed and adhere to the skin. This invention uses airbag pressure to create a closer fit for the far-infrared material, enhancing the efficiency of far-infrared release and promoting fat metabolism.

[0057] Example 2: As shown in the attached Figure 3 As shown, the present invention also provides an intelligent control method for intelligent slimming underwear, which is applied to embodiment 1 and includes the following steps:

[0058] S1. Using wireless terminals installed on the outer periphery of the top and bottom garments, the user-set target pressure value, pressurization area selection, and pressurization duration are obtained. The pressurization area includes at least one of the upper limbs above the elbow joint, abdomen, thigh, and buttocks. The pressurization duration is divided into multiple cycles, with each cycle alternating between an inflation and pressurization phase and an exhaust and relaxation phase. The ratio of the inflation and pressurization phase to the exhaust and relaxation phase ranges from 1:1 to 3:1. The user-set target pressure value, pressurization area, and duration are obtained through the wireless terminal, enabling personalized weight loss plan settings. Users can select key weight loss areas based on their needs and set appropriate pressure and time, improving the targetedness and flexibility of weight loss.

[0059] S2. Activate the micro air pumps and micro solenoid valves in the corresponding zones according to the selected pressurized areas. The upper garment area is supplied with air by the first micro air pump, while the lower garment area is supplied with air by the second micro air pump. This ensures that only the airbags in the target area are inflated and deflated, preventing non-target areas from being pressurized, thereby improving energy utilization efficiency and control accuracy.

[0060] S3. Inflate the target flexible airbag using a micro air pump. The pressure sensor monitors the actual pressure value in the airbag in real time and compares the actual pressure value with the target pressure value. The target pressure value is set according to the body position. From bottom to top, from the calf to the thigh and buttocks, the pressure gradually decreases, thereby preventing water and blood metabolism disorders or edema. The micro solenoid valve opening and air pump power are dynamically adjusted by the PID algorithm. When the actual pressure value reaches the target pressure value and remains stable, the constant pressure holding stage is entered. When the kth sampling is performed at a sampling period of T, the error e(k) is calculated by comparing the actual pressure value with the target pressure value using the following formula:

[0061] e(k)=P t -P a (k)

[0062] Among them, P t The target pressure value set by the user, P a (k) is the actual pressure value fed back by the pressure sensor;

[0063] The micro solenoid valve opening and air pump power are dynamically adjusted through the PID algorithm. The PID output is:

[0064]

[0065] Among them, K p , K i , K d are proportional, integral and differential coefficients respectively, and u(k) is the control output; the control output u(k) is decomposed into the coordinated control of the air pump power and the solenoid valve opening, so that the air pump and the solenoid valve complement each other, that is, the solenoid valve is closed during inflation and opened during decompression;

[0066] The constant pressure holding stage begins when the following conditions are met:

[0067] and max i∈[k-N+1,k] P a (i)-min i∈[k-N+1,k] P a (i)≤ε

[0068] Where δ represents the allowable average error threshold, ε represents the allowable pressure fluctuation threshold, and N is the continuous sampling window size.

[0069] The air pump inflates the flexible airbag, and the pressure sensor monitors the pressure in real time. The air pump power and the opening of the micro solenoid valve are adjusted through the PID algorithm to achieve dynamic pressure control. After reaching the target pressure and stabilizing, it enters the constant pressure stage, thereby accurately controlling the pressure to avoid discomfort caused by excessively high pressure or affecting the effect due to too low pressure. Constant pressure can maintain continuous pressurization stimulation and enhance the weight loss effect.

[0070] S4. During the inflation of the flexible airbag, the graphene bumps are synchronously triggered to press the corresponding acupuncture points. Combining the principles of traditional acupuncture point massage, the graphene bumps stimulate the acupuncture points through pressing, regulating body metabolism and assisting weight loss. The pressing depth of the graphene bumps is controlled by establishing a mapping relationship between airbag pressure and bump displacement. The target pressure value is adjusted to indirectly control the depth of the bumps sinking into the skin. The depth control range is 1-3mm, and the corresponding pressure value is 30%-70% of the target pressure value for the partition.

[0071] According to the airbag pressure-bump displacement mapping relationship table, a piecewise linear mapping function is established, which is expressed as:

[0072]

[0073] Among them, d min is the minimum effective depth of the linear working area, which is 1mm. max is the maximum displacement value of the saturation zone, which is 3 mm. k1 is the linear coefficient of the initial elastic zone. P1 is the pressure limit threshold for entering the linear working zone. k2 is the slope of the linear working zone. P2 is the pressure limit threshold for entering the saturation zone.

[0074] According to different pressurization areas, use the following formula to obtain the actual control target pressure value:

[0075] P c =min(max(P t ,0.3P t ),0.7P t )

[0076] Among them, P t The target pressure value set by the user, P c is the target pressure value for actual control.

[0077] During the pressurization process, the far-infrared emitting material in the interlayer continuously releases far-infrared rays. The flexible airbag pressurizes the material, allowing it to adhere to the skin and absorb body heat. This heat, in turn, stimulates the material to continuously release far-infrared rays with a wavelength of 4-14 microns, raising the temperature of fat cells and accelerating fat metabolism. The far-infrared rays act on fat cells, accelerating fat metabolism and creating a synergistic effect with the pressurization and acupoint stimulation, enhancing overall weight loss efficiency.

[0078] S6. When the set pressurization time is reached, or the pressure sensor detects that the pressure exceeds the threshold, the micro air pump is turned off and the micro solenoid valve is opened to exhaust, thereby preventing safety hazards caused by excessive pressurization, ensuring user safety, and ending a complete weight loss process.

[0079] The second micro-pump's pressurization pressure is different from the first. It gradually decreases from the thigh to the buttocks and finally to the abdomen. This pressure setting is intended to promote blood and fluid circulation in the lower limbs and prevent edema. The pressurization time is also time-limited and can be customized through the wireless terminal's options. For example, setting the time from 8:00 AM to 8:00 PM allows for 10 minutes of pressurization every 30 minutes, or 5 minutes every 15 minutes. This prevents prolonged pressurization and the risk of venous thrombosis, especially in the elderly.

[0080] As can be seen from the above, by establishing a mapping relationship table between the airbag pressure and the pressing depth of the bump, the depth of the bump sinking into the skin is indirectly controlled by adjusting the target pressure to 1-3mm, thereby realizing quantitative control of the massage intensity, which is more accurate and repeatable than the traditional manual adjustment of the massage intensity; the pressurization time is divided into alternating cycles of inflation and exhaust, simulating the "press-release" rhythm of massage, avoiding poor blood circulation caused by continuous pressurization, and enhancing fat metabolism efficiency through periodic stimulation. Existing smart underwear mostly uses continuous pressurization or simple timing control, lacking this dynamic rhythm adjustment; at the same time, the user parameters can be independently set to target pressure, area, and duration through the wireless terminal, and the control process is automatically executed according to the parameters. Compared with the existing fixed-mode slimming underwear, it can better meet the individual needs of different users; and the PID algorithm is used for dynamic pressure adjustment, combined with the pressure sensor to achieve adaptive control, improve the robustness and anti-interference ability of the system, and adapt to the changes in body position and skin elasticity when worn by different users.
