[0018] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0019] like Figures 1-4 As shown, this embodiment of a health care belt includes a body 1, a graphene heating layer 2 disposed inside the body 1, and a controller 3 detachably connected to the body 1. The controller 3 is electrically connected to the graphene heating layer 2.

[0020] The main body 1 includes a first patch 4 and a second patch 5. The first patch 4 corresponds to the area of ​​the human abdomen when in use, and the second patch 5 corresponds to the area of ​​the human lower back when in use. The first patch 4 and the second patch 5 can be made of flexible fabric or elastic fabric so that they can conform to the physiological curve of the human waist. The main body 1 also includes a first connecting part 6 disposed between the first patch 4 and the second patch 5. The first connecting part 6 is a flexible strip structure, and its two ends are fixedly connected to the first patch 4 and the second patch 5 respectively, for example by sewing or gluing. The side of the first patch 4 away from the first connecting part 6 is connected to a second connecting part 7, and the side of the second patch 5 away from the first connecting part 6 is connected to a third connecting part 8. The third connecting part 8 is used to detachably connect to the second connecting part 7.

[0021] In a preferred embodiment, the first connecting part 6 is a woven tape or an elastic band, giving the body 1 a certain degree of flexibility and stretching allowance between the two application parts, which can adapt to users of different body types; the second connecting part 7 is a hook and loop fastener, and the third connecting part 8 is a hook and loop fastener, or the third connecting part 8 is a hook and loop fastener and the second connecting part 7 is a hook and loop fastener, and the belt is fixed at the waist by the adhesive fit between the hook and loop fastener; the width of the hook and loop fastener and the hook and loop fastener is 3cm to 6cm, and the length is determined according to the overall size of the belt to ensure sufficient adhesive area and fixing strength.

[0022] The controller 3 and the main body 1 are detachably mechanically connected via a snap-fit ​​structure. The snap-fit ​​structure includes a protrusion on the housing of the controller 3 and a slot on the main body 1. The slot is L-shaped and includes a longitudinal section and a transverse section that are interconnected. The longitudinal section extends longitudinally from the opening end of the slot, and the transverse section extends laterally from the end of the longitudinal section. After the protrusion enters the longitudinal section from the opening end of the slot, it slides along the longitudinal section to the intersection of the longitudinal and transverse sections, and then slides along the transverse section to the end of the transverse section. The protrusion engages with the end of the transverse section to achieve a fixed connection between the controller 3 and the main body 1. When it is necessary to disassemble the controller 3, the protrusion is slid in the opposite direction from the end of the transverse section along the transverse and longitudinal sections to the opening end of the slot, and the controller 3 can be removed from the main body 1.

[0023] In one specific embodiment, the controller 3 and the main body 1 are detachably electrically connected via contact terminals. The bottom of the controller 3 is provided with a first contact terminal, and the corresponding position on the main body 1 is provided with a second contact terminal, with the positions of the first contact terminal and the second contact terminal corresponding to each other. The second contact terminal is electrically connected to the electrode of the graphene heating layer 2, the therapeutic electrode 9, the red light generator 10, and the temperature sensor via wires. When the controller 3 is installed on the main body 1 via a snap-fit ​​structure and the protrusion slides to the end of the transverse section of the slot, the first contact terminal and the second contact terminal abut against each other and establish an electrical connection. Each drive circuit of the controller 3 is connected to the graphene heating layer 2, the therapeutic electrode 9, the red light generator 10, and the temperature sensor, respectively. When the controller 3 is removed from the main body 1, the first contact terminal and the second contact terminal separate, and the electrical connection between the controller 3 and each electrical control on the main body 1 is simultaneously disconnected.

[0024] In another specific embodiment, the controller 3 and the main body 1 can also achieve a detachable electrical connection through the cooperation of the plug-in end and the plug-in slot; the bottom of the controller 3 is provided with a plug-in end, and the corresponding position of the main body 1 is provided with a plug-in slot, and the plug-in end and the plug-in slot are plugged in and cooperate; the opening size of the plug-in slot is larger than the cross-sectional size of the plug-in end, so that the plug-in end has a certain horizontal movement margin in the plug-in slot. The insertion slot is electrically connected to the electrical electrode of the graphene heating layer 2, the physiotherapy electrode 9, the red light generator 10 and the temperature sensor respectively through wires; when the controller 3 is installed on the body 1 through the snap-fit ​​structure, the protrusion enters the longitudinal section from the opening end of the slot and slides along the longitudinal section, and the insertion end is inserted into the insertion slot as the controller 3 moves horizontally, and slides horizontally in the insertion slot to the working position. When the protrusion slides to the intersection of the longitudinal and transverse sections and slides along the transverse section to the end of the transverse section, the plug end moves to the final working position in the plug slot with the controller 3 and establishes a stable electrical connection. Each drive circuit of the controller 3 is connected to the graphene heating layer 2, the physiotherapy electrode 9, the red light generator 10 and the temperature sensor respectively. When the controller 3 is removed from the body 1, the protrusion slides in the opposite direction from the end of the transverse section along the transverse and longitudinal sections. The plug-in end slides in the plug-in slot and gradually disengages as the controller 3 moves horizontally in the opposite direction. When the protrusion slides to the opening end of the slot, the plug-in end completely exits the plug-in slot, and the electrical connection between the controller 3 and each electrical control on the body 1 is disconnected at the same time.

[0025] The controller 3 is equipped with a main control chip and a drive circuit. The main control chip is a microcontroller, such as an ARM Cortex-M series or an 8051 series microcontroller, which integrates a memory, a timer and an analog-to-digital converter. The memory is used to store programs and parameter configurations for various physiotherapy projects, the timer is used to generate PWM signals and various timing controls, and the analog-to-digital converter is used to acquire analog signals from the temperature sensor. The driving circuit includes a graphene heating layer 2 driving circuit, a physiotherapy electrode 9 driving circuit, and a red light generator 10 driving circuit; the graphene heating layer 2 driving circuit is a MOSFET switching circuit or a relay circuit, which adjusts the effective heating power of the graphene heating layer 2 through a PWM signal. The driving circuit for the physiotherapy electrode 9 is a pulse generation circuit, including a boost circuit and a pulse output circuit. It boosts the low-voltage pulse signal output by the main control chip to 10V to 60V and then outputs it to the physiotherapy electrode 9. The driving circuit for the red light generator 10 is a constant current driving circuit, which provides a stable operating current for the red light LED beads.

[0026] The control unit 3 has a control panel on its outer casing, which includes a power switch and multiple adjustment buttons. These adjustment buttons include buttons for adjusting the heating temperature, electrical stimulation intensity, and phototherapy intensity. The control unit 3 also has a power interface, which can be a USB Type-C interface, a Micro-USB interface, or a DC round hole interface, for connecting external power supply devices such as power banks or USB power adapters. The control unit 3 can also have a rechargeable battery inside, such as a lithium-ion battery or a lithium polymer battery, so that the user can use the belt normally without an external power source.

[0027] The power interface is connected to the power management module of the main control chip via wires, providing the operating voltage for the entire control unit 3. The power management module includes a charging management circuit, a voltage regulator circuit, and a battery protection circuit, which can regulate the external input power and manage the charging of the internal battery. Multiple signal output terminals of the main control chip are connected to the driving circuits of the graphene heating layer 2, the physiotherapy electrode pad 9, and the red light generator 10 via wires, respectively. The switch button, the heating temperature adjustment button, the electrical stimulation intensity adjustment button, and the phototherapy intensity adjustment button are respectively connected to the corresponding signal input terminals of the main control chip.

[0028] After the user connects to an external power source via the power interface and presses the switch button, the main control chip is powered on and starts up. After initialization, the main control chip enters standby mode, waiting for the user to input commands via the adjustment keys. The user sets the heating temperature of the graphene heating layer 2 via the heating temperature adjustment keys, which can be set from 30℃ to 55℃. Each press of the adjustment key changes the temperature by 1℃ or 2℃. The main control chip outputs a PWM signal with a duty cycle of 0% to 100% to the driving circuit of the graphene heating layer 2 according to the set value, driving the graphene heating layer 2 to heat up to the set temperature. The user sets the electrical stimulation intensity of the physiotherapy electrode 9 using the electrical stimulation intensity adjustment key. The intensity can be set from 1 to 10 levels, each corresponding to a different pulse voltage or pulse width. The main control chip outputs pulse signals with a frequency of 1Hz to 200Hz and a pulse width of 50μs to 5ms to the driving circuit of the physiotherapy electrode 9 according to the set value, driving the physiotherapy electrode 9 to output electrical stimulation of the corresponding intensity. The user sets the light emission intensity of the red light generator 10 using the phototherapy intensity adjustment key. The intensity can be set from 1 to 5 levels, each corresponding to a different driving current. The main control chip outputs a driving current of 300mA to 1.4A to the driving circuit of the red light generator 10 according to the set value, driving the red LED beads to emit light at the corresponding brightness.

[0029] The graphene heating layer 2, the physiotherapy electrode pad 9, and the red light generator 10 are independent of each other and can be independently controlled by the user to turn on, off, and adjust the intensity through the corresponding adjustment keys on the control panel, without interfering with each other; the user can choose to turn on any one of the functions individually, or turn on two or more functions at the same time according to their own needs.

[0030] The graphene heating layer 2 includes a flexible substrate layer, a graphene heating film layer, and an insulating protective layer stacked sequentially. The flexible substrate layer serves as the supporting base and is made of a flexible polymer material, such as a polyimide film, a polyethylene terephthalate film, or a polyethylene naphthalate film, with a thickness of 0.05 mm to 0.3 mm. The flexible substrate has good flexibility, heat resistance and electrical insulation, and can bend with the body 1 without breaking; the graphene heating film layer is coated or attached to the surface of the flexible substrate layer and is the main heating functional layer, with a thickness of 10μm to 300μm. The graphene heating film is formed by coating, drying and curing graphene slurry. The graphene slurry contains graphene powder, conductive additives and binding resin, and is uniformly coated on the surface of a flexible substrate by screen printing, gravure printing or slot coating. An insulating protective layer covers the graphene heating film layer, which serves to insulate and protect against leakage and external damage. The material used is polyimide film, PET film or epoxy resin insulating coating, with a thickness of 0.02mm to 0.1mm.

[0031] The graphene heating film has electrodes on both sides. The electrodes are silver paste electrodes, which are formed on both sides of the graphene heating film by screen printing. The width of the silver paste electrodes is 3mm to 10mm and the thickness is 5μm to 30μm. The silver paste electrodes have the advantages of good conductivity and strong adhesion. The electrodes are electrically connected to the controller 3 through wires. The wires are flexible wires, such as silicone insulated electronic wires or enameled wires. One end of the wire is welded or crimped to the surface of the silver paste electrode, and the other end is connected to the corresponding output terminal of the controller 3. The controller 3 applies a working voltage to the electrodes through the wires. The voltage is usually a DC voltage of 5V to 24V. The current flows into the graphene heating film through the electrodes. The graphene heating film generates heat after being energized.

[0032] Both the first application part 4 and the second application part 5 have a graphene heating layer 2 inside. That is, the first application part 4 has a first graphene heating element inside, and the second application part 5 has a second graphene heating element inside. Both the first and second graphene heating elements have the above-mentioned stacked structure of a flexible substrate layer, a graphene heating film layer, and an insulating protective layer. The first graphene heating element is embedded in the interlayer of the first application part 4, and the second graphene heating element is embedded in the interlayer of the second application part 5. They are fixed inside the application part by sewing or hot pressing. The two graphene heating elements are electrically connected to the controller 3 through their respective wires, and the controller 3 independently controls the heating.

[0033] After the controller 3 is powered on, a voltage is applied to the graphene heating film layer through wires and electrodes. The carbon atoms in the graphene heating film layer undergo violent collisions and friction under the action of the electric field, converting electrical energy into heat energy and generating heat. Since the graphene heating film layer is a continuous planar heating body, the heat is evenly distributed on the entire surface of the film layer, and the heating temperature difference does not exceed ±3℃, avoiding the problem of local overheating or underheating caused by the linear heating of traditional resistance wires or carbon fiber heating wires. The flexible substrate layer allows the heating layer to bend with the body 1 and conform to the curve of the human waist. The insulating protective layer ensures that the heating layer is insulated from the outside world, ensuring safe use.

[0034] In a preferred embodiment, the graphene heating layer 2 is also provided with a temperature sensor; the temperature sensor is a patch-type NTC thermistor or thermocouple, which is bonded to the surface of the graphene heating film layer or the back of the flexible substrate layer by thermally conductive adhesive; the temperature sensor is electrically connected to the controller 3 through a signal wire, and is used to detect the heating temperature of the graphene heating layer 2 in real time and feed the temperature signal back to the controller 3; The main control chip receives feedback signals from the temperature sensor and compares them with preset temperature values. It then uses a PID algorithm or switching control to perform closed-loop regulation of the output power, stabilizing the temperature of the graphene heating layer 2 near the set value with an accuracy of ±2℃. When the temperature sensor detects that the temperature of the graphene heating layer 2 exceeds the safety threshold, such as 55℃ or 60℃, the main control chip immediately cuts off the power supply to the graphene heating layer 2 to achieve overheat protection. As a double protection, a thermal protector, such as a bimetallic temperature control switch or a one-time thermal fuse, can be connected in series in the circuit of the graphene heating layer 2. When the temperature rises abnormally, the thermal protector automatically disconnects the circuit.

[0035] In this embodiment, a plurality of therapeutic electrode pads 9 are provided on one side surface of the main body 1. More specifically, the therapeutic electrode pads 9 can be provided on one side surface of the first application part 4 and the second application part 5, which is the side surface facing the human skin during use. The therapeutic electrode pads 9 are conductive silicone pads made of conductive silicone material, which have good conductivity, flexibility and skin affinity, and can fit well with human skin. The shape of the therapeutic electrode pads 9 is circular, elliptical or rectangular, with a diameter of 20mm to 50mm and a thickness of 1mm to 3mm. The therapeutic electrode pads 9 are electrically connected to the control unit 3 through wires. One end of the wire is connected to the therapeutic electrode pad 9 by means of metal snap, magnetic snap or welding, and the other end is connected to the corresponding output terminal of the control unit 3.

[0036] As one arrangement, several therapeutic electrode pads 9 are arrayed on one side surface of the body 1; the array includes a first electrode area distributed longitudinally along the body 1 and a second electrode area distributed transversely along the body 1; the first electrode area is located on both sides of the longitudinal central axis of the body 1, including a left longitudinal electrode area and a right longitudinal electrode area, each longitudinal electrode area containing 2 to 4 electrode pads, arranged at equal intervals along the longitudinal direction, with a spacing of 3cm to 6cm; the second electrode area is located in the transverse flank area of ​​the body 1, that is, the left and right extensions of the first application part 4 and the second application part 5, each flank area containing 1 to 3 electrode pads; each electrode pad is insulated from each other and is independently addressed and controlled by the controller 3.

[0037] As another arrangement method, the physiotherapy electrode pads 9 are arranged according to the anatomical location of acupoints in the human waist. For example, the electrode pads located on both sides of the longitudinal central axis of the body 1, 3cm to 5cm away from the central axis, correspond to the Shenshu acupoint. The electrode pad located on the longitudinal central axis of the body 1, corresponding to the lower part of the spinous process of the second lumbar vertebra, corresponds to the Mingmen acupoint. The electrode pad located on the transverse flank of the body 1, corresponding to the upper edge of the iliac crest, corresponds to the Daimai acupoint. The electrode pad located in the first application part 4, corresponding to the abdominal area, corresponds to the Tianshu or Shuifen acupoint. The control unit 3 has pre-stored various electrode pad activation schemes and pulse parameters corresponding to different physiotherapy projects. The user selects different physiotherapy projects through the control unit 3. The control unit 3 activates the combination of physiotherapy electrode pads 9 in different positions according to the preset scheme, and outputs the corresponding pulse frequency and pulse width to achieve targeted acupoint electrical stimulation.

[0038] The controller 3 is equipped with a pulse generation circuit that can generate pulse currents with specific frequencies of 1Hz to 200Hz and pulse widths of 50μs to 5ms. The pulse current is transmitted to the physiotherapy electrode pads 9 through wires. The physiotherapy electrode pads 9 conduct the pulse current to the surface of the human skin, stimulating subcutaneous muscles and nerve tissue, causing rhythmic passive muscle contraction. The physiotherapy electrode pads 9 at different locations can be independently controlled by the controller 3 to be turned on or off, thereby achieving selective stimulation of different acupoints or muscle groups.

[0039] In this embodiment, a red light generator 10 is provided on one side surface of the main body 1. The red light generator includes an LED light board with multiple red LED beads. The main body has a mounting hole at the position corresponding to the LED light board. More specifically, the red light generator 10 can be provided on one side surface of the first application part 4 and the second application part 5. This side surface is the side surface facing the human skin during use. The red light generator 10 is electrically connected to the controller 3.

[0040] The red light generator 10 includes a light source module and a light guide component. The light source module is located inside the first application part 4 and the second application part 5, behind the light guide component, and does not directly contact the human skin. The light guide component is located on one side surface of the first application part 4 and the second application part 5, that is, the side facing the human skin when in use. Its light-inlet end is opposite to the light source module or connected through a light guide medium, and its light-outlet end faces the human skin. The light source module is an LED light board, which has multiple red LED beads that can emit red light with a wavelength of 660nm to 880nm. The light source module is electrically connected to the controller 3, which provides constant current drive to the light source module with a current of 300mA to 1.4A. The light guide component is made of transparent or semi-transparent light guide material, such as light guide plate, light guide column, fiber bundle or light guide gel, which can conduct the red light emitted by the light source module from the light input end to the light output end; the first application part 4 and the second application part 5 have light output holes at the positions corresponding to the light output end of the light guide component. The light output holes are through holes that penetrate the fabric of the application part. The light output end of the light guide component is embedded in the light output hole and fixed by adhesive or sewing, so that the light output end is exposed on one side surface of the application part. After the light source module is powered on, multiple red LED beads light up simultaneously. The emitted red light enters the light-inlet end of the light guide component through the light-emitting surface of the light source module, and is then conducted to the light-emitting end through the light guide component. The red light is emitted from the light-emitting end and directly irradiates the skin surface of the human waist, producing a photobiological regulatory effect on the subcutaneous tissue and promoting local blood circulation and metabolism.

[0041] In a preferred embodiment, the control unit 3 is also equipped with a wireless communication module; the wireless communication module is a Bluetooth module, supporting Bluetooth 4.0 and above, or a WiFi module, supporting the 802.11b / g / n standard, for data interaction with external terminal devices such as mobile phones and tablets; users can remotely control the control unit 3 through an application on the external terminal device, including selecting physiotherapy programs, adjusting various function parameters, viewing the current working status and historical usage records, to achieve a more convenient operating experience.

[0042] In this embodiment, the controller 3 may have a built-in battery, meaning that the controller 3 also serves as a power supply; alternatively, the controller 3 may be connected to an external power source via a power cord, serving only as a controller for electrical appliances.

[0043] The working process and principle of this invention are as follows: When in use, the user wraps the main body 1 around the waist, with the first patch 4 located in the abdominal area and the second patch 5 located in the lower back area. The waist belt is fixed to the waist by the adhesive cooperation of the second connecting part 7 (hook and loop tape) and the third connecting part 8 (hook and loop hook tape). The tightness is adjusted to a comfortable position. At this time, the physiotherapy electrode 9 and the red light generator 10 on one side of the first patch 4 and the second patch 5 are in close contact with the skin of the waist. The graphene heating layer 2 is located inside the main body 1, and the heat is conducted to the skin through the fabric of the main body 1.

[0044] The user connects an external power source, such as a power bank, to the control unit 3 via the power interface and presses the power switch to start the control unit 3. The user can adjust the heating temperature of the graphene heating layer 2 to a suitable level using the heating temperature adjustment key (which can include low, medium, and high temperature levels), adjust the electrical stimulation intensity of the physiotherapy electrode pads 9 to a suitable level using the electrical stimulation intensity adjustment key, and adjust the light emission intensity of the red light generator 10 to a suitable level using the phototherapy intensity adjustment key (which can include strong, medium, and weak levels). Multiple functions can be adjusted independently, used individually, or used simultaneously. During use, the temperature sensor continuously monitors the temperature of the graphene heating layer 2 and feeds the signal back to the main control chip, which automatically adjusts the output power to maintain the set temperature. The recommended usage time is 15 to 30 minutes per session, depending on individual tolerance.

[0045] After use, press the switch button to turn off the control unit 3, disconnect the power interface from the external power supply, and remove the belt from the waist by unfastening the Velcro. If you need to clean the main body 1, slide the protrusion from the end of the horizontal section of the slot in the opposite direction along the horizontal and vertical sections to the opening end of the slot. Remove the control unit 3 from the main body 1 and clean the main body 1 separately. It can be hand-washed or machine-washed, and the water temperature should not exceed 40℃. After cleaning, let it air dry naturally, avoiding exposure to the sun or high-temperature drying. After drying, align the protrusion with the opening end of the slot, slide it along the vertical section to the intersection of the vertical and horizontal sections, and then slide it along the horizontal section to the end of the horizontal section so that the protrusion engages with the end of the horizontal section. Reinstall the control unit 3 on the main body 1 for reuse.
