Description

Technical Field

[0001] This invention belongs to the field of fitness equipment technology, specifically relating to a fitness vibration fat-burning device system and method with electrical conduction stabilization function, and is particularly suitable for fat-burning devices controlled by wireless communication. Background Technology

[0002] Fat-burning machines are a common type of fitness and body-shaping equipment. They utilize the principle of high-frequency vibration in physical processes, causing the body to vibrate and slowly generate heat, promoting fat burning and thus achieving a warm-up effect. With technological advancements, some fat-burning machines have begun to integrate electrotherapy functions. Electrodes are placed on the pedals, which contact the soles of the feet when the user stands, forming an electrotherapy circuit to achieve better fitness results. Furthermore, as fat-burning machines become more intelligent and wireless, they typically integrate Bluetooth or Wi-Fi modules to connect to a mobile app, enabling functions such as uploading exercise data and switching modes.

[0003] Problems with existing technology: 1. Currently, the electrical conduction modules used in existing vibratory fat-burning devices are usually connected by spot welding. However, during use, this structure is prone to poor contact of the electrotherapy contacts due to the high-frequency vibration of the fat-burning device, which affects the stability of the electrical conduction function.

[0004] 2. In the process of using traditional electrical conduction modules, the contact between the electrical conduction module and the human foot cannot be adaptively adjusted due to the existence of the forefoot, arch, and heel areas of the human foot. This further affects the stability of the electrical conduction to the human body during the high-frequency vibration of the fat-burning device.

[0005] 3. Currently available vibration fat-burning devices typically incorporate a wireless communication module into the main control unit for convenient control, considering the need for intelligence. However, if the wireless communication module operates continuously at high power, it will not only rapidly consume battery power, leading to a shortened battery life, but may also cause unstable circuit current due to power consumption fluctuations, thereby affecting the output stability of the electrical pulse generator and the stability of electrical conduction. Summary of the Invention

[0006] The purpose of this invention is to provide a fitness vibration fat-burning device system and method with electrical conduction stabilization function. It can eliminate contact displacement deviation caused by high-frequency vibration of the fat-burning machine by adding a multi-directional clamping mechanism and a through-hole protrusion for complementary interlocking, and with the help of a floating conductive slide column. At the same time, it can improve the stability of electrical conduction by controlling the power consumption of the wireless communication module in the main control unit.

[0007] The specific technical solution adopted by this invention is as follows: A fitness vibration fat-burning device system and method with electrical conduction stabilization function includes a fat-burning device body and a vibration fat-burning unit disposed inside the fat-burning device body for generating mechanical vibration. The vibration fat-burning unit drives a vibration plane to drive the electrical conduction module to vibrate, and detects the user's movement state through an inertial measurement unit installed inside the vibration plane. Radio frequency microcurrent generator, used to generate low-frequency pulsed current that acts on the human body; The main control unit is used for data interaction with external terminals; An electrical conduction stability monitoring module is used to monitor the output parameters of the electrical conduction module in real time and generate an electrical conduction stability assessment value based on the monitoring results. The muscle fatigue monitoring module is used to collect the user's muscle physiological signals and generate a muscle fatigue assessment value based on the muscle physiological signals. The power consumption control module is electrically connected to the vibration fat-burning unit, the electrical conduction module, the main control unit, and the electrical conduction stability monitoring module, respectively. It is used to dynamically adjust the power consumption mode of the wireless communication module in the main control unit according to the electrical conduction stability evaluation value and the working state of the vibration fat-burning unit, so that the radio frequency micro-current generator generates a stable low-frequency pulse current that is conducted to the human body.

[0008] The muscle fatigue monitoring module is integrated inside the main control unit. The muscle fatigue monitoring module includes a surface electromyography sensor for collecting the user's surface electromyography signals. The muscle fatigue monitoring module has a built-in fatigue detection algorithm that extracts the feature parameters of the surface electromyography signals and outputs the muscle fatigue assessment value. The main control unit dynamically adjusts the power of the radio frequency microcurrent generator based on the muscle fatigue assessment value.

[0009] The electrical conduction module includes multiple conductive sliding pillars and a multi-directional clamping mechanism. The multi-directional clamping mechanism is vertically inserted into the substrate and extends upward to the surface of the elastic insulating layer. The conductive sliding pillars drive the electrode head to slide and engage with the multi-directional clamping mechanism. The bottom of the conductive through-hole protrusion of the multi-directional clamping mechanism is electrically connected to the radio frequency microcurrent generator, so that the low-frequency pulse current generated by the radio frequency microcurrent generator is conducted to the human body.

[0010] The multi-directional interlocking mechanism includes multiple snap-fit ​​protrusions disposed on the periphery of the conductive via protrusions, and interlocking grooves disposed on the surface of the elastic insulating layer and the substrate that are adapted to the snap-fit ​​protrusions. The conductive via protrusions and insert grooves form a complementary press-fit in multiple directions to limit the relative displacement of the multi-directional insert mechanism with respect to the elastic insulating layer and the substrate when the electrical conduction module vibrates.

[0011] The locating groove includes multiple grooves corresponding to the number of conductive via protrusions, and each groove has an inlet ramp that matches the guide surface of the conductive via protrusion, and a locking surface that abuts against the limiting wall of the locating groove. The limiting wall is L-shaped, and there is an angle between one end of the guide slope and the limiting wall, so that the conductive through hole protrusion can be limited in multiple directions after being embedded in the groove.

[0012] The electrical conduction module also includes an annular conductive slip ring disposed inside the conductive through-hole protrusion, and a spring fixedly installed inside the conductive through-hole protrusion. The spring is used to push the conductive slip ring to drive the electrode head to abut against the sole of the foot. The annular groove on the surface of the conductive slide column slides in conjunction with the conductive slip ring to limit the sliding distance of the electrode head driven by the conductive slide column.

[0013] The electrode head is provided with multiple conductive via protrusions, and the bottom of each of the multiple conductive via protrusions is welded with multiple terminals. The multiple terminals are connected in series by conductive wires and electrically connected to the radio frequency microcurrent generator through the conductive wires.

[0014] The motor fixedly installed inside the bottom shell is used to drive the shaft to rotate. The shaft is used to drive the eccentric wheels at both ends to rotate synchronously, so that the eccentric wheels drive the first magnetic block and the second magnetic block to move in a circular motion. The S pole of the first magnetic block and the N pole of the second magnetic block both face the center of the eccentric wheel. One set of the eccentric wheels is attracted to the electromagnet by opposite poles through the first magnetic block, while the other set of the eccentric wheels is repelled by like poles of the electromagnet, so that the electromagnet drives the vibrating plane to move through the mounting frame.

[0015] A method for stabilizing electrical conduction includes the following steps: The real-time output parameters of the electrical conduction module are obtained, including the operating current and operating voltage. Obtain the deviation value between the operating current and the preset standard current, as well as the ripple coefficient of the operating voltage, and determine the current electrical conduction stability assessment value based on the deviation value of the current and the ripple coefficient. The current working status of the vibration fat-removing unit is obtained based on the inertial measurement unit; Based on the electrical conduction stability assessment value and the operating state of the vibration-induced fat-removing unit, the power consumption mode of the wireless communication module in the main control unit is dynamically adjusted, wherein: If the electrical conduction stability assessment value is lower than the first preset threshold, the power consumption control module controls the wireless communication module to switch from high power consumption mode to low power consumption mode; If the electrical conduction stability assessment value remains below the second preset threshold and the vibration fat-removing unit is in a high-frequency vibration state, the power consumption control module controls the wireless communication module to switch from a low-power mode to a deep sleep mode.

[0016] The power consumption control module includes: A state machine unit is used to define wireless communication power consumption states, including at least a high-power mode, a low-power mode, and a deep sleep mode. The decision unit is used to control the wireless communication module to switch from a high-power mode to a low-power mode and from a low-power mode to a deep sleep mode when the electrical conduction stability assessment value is lower than a preset threshold.

[0017] The technical effects achieved by this invention are as follows: This invention, by setting grooves corresponding to the buckle protrusions inside the embedding groove, with each groove having an guide slope that mates with the guide surface of the buckle protrusion and a limiting wall that abuts against the locking surface of the buckle protrusion, and an angle between the guide slope and the limiting wall, allows the buckle protrusion to be limited in multiple directions after being embedded in the embedding groove. Through the complementary engagement formed by the multi-directional embedding mechanism and the elastic insulating layer, the relative displacement between the conductive through-hole protrusions and the pedal base plate motor can be limited from multiple directions during high-frequency vibration of the fat-burning device, effectively eliminating contact displacement deviation caused by high-frequency vibration, ensuring stable contact conduction between the electrotherapy circuit and the limb, and also avoiding the problem of poor contact of the electrical conduction contacts in the transmission spot welding caused by mechanical vibration, significantly improving the stability of the electrical conduction function.

[0018] In this invention, a spring is fixedly installed inside the conductive through-hole protrusion, and the top of the spring extends upward into the interior of the conductive slide post and is fixedly installed therewith. Simultaneously, a conductive slip ring is also provided inside the conductive through-hole protrusion, and the conductive slip ring slides in cooperation with an annular groove on the side of the conductive slide post. Therefore, the vertical movement of the conductive slide post is limited by the annular groove, and the elasticity of the spring ensures that the conductive slide post can drive the electrode head to maintain constant contact with the forefoot, arch, and heel areas of the user's foot, ensuring the stability of the electric drive.

[0019] This invention utilizes a power consumption control module and an electrical conduction stability monitoring module internally located within the body of the fat-burning device. The power consumption control module is electrically connected to the main control unit, while the electrical conduction stability monitoring module includes a current sensor and a voltage sensor. The current sensor is connected in series in the circuit supplying power from the battery module to the electrical conduction module to collect the operating current of the electrical conduction module in real time. The voltage sensor is connected in parallel at the output terminal of the electrical conduction module to collect the output voltage in real time. An electrical transmission stability assessment value is generated based on the operating current, operating voltage, and vibration plane motion collected by the inertial measurement unit. Through the cooperation of the power consumption control module and the electrical conduction stability monitoring module, the power consumption mode of the wireless communication module in the main control unit can be dynamically adjusted according to the assessment value. When a decrease in electrical conduction stability is detected, the power consumption control module of the main control unit will prioritize reducing the power consumption of the wireless communication module to avoid circuit current fluctuations caused by high power consumption operation, thereby ensuring the output stability of the electrical conduction module of the electric pulse generator. At the same time, a balance between battery life and functionality is achieved through graded control of power consumption mode.

[0020] In this invention, a heating module is embedded inside the elastic insulating layer. By improving the serpentine winding path of the heating resistance wire and the arrangement of the conductive through-hole protrusions, the local overheating caused by uneven heat source distribution can be effectively suppressed, the heat exchange efficiency between the heating module and the sole of the human foot is enhanced in low-temperature environments, and the effect of the vibration fat-burning device is further improved.

[0023] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0024] like Figure 1-15 As shown, a fitness vibration fat-burning device system with electrical conduction stabilization function includes the following preferred embodiments: Inside the body 1 of the fat-burning device, there is a vibrating fat-burning unit 3 for generating mechanical vibration. The vibrating fat-burning unit 3 includes a motor 31 fixedly installed inside the bottom shell 11. The motor 31 can drive the shaft 32 to rotate at high speed inside the bottom shell 11 through the transmission wheel and the transmission belt.

[0025] Furthermore, a first magnetic block 322 and a second magnetic block 323 are installed inside the two eccentric wheels 321. At the same time, an electromagnet 331 with the N pole facing down and an S pole facing down are installed inside the two mounting brackets 33 respectively. Therefore, during the rotation of the eccentric wheels 321 at both ends driven by the shaft 32, it can be ensured that one end belongs to the same pole repulsion and the other end belongs to opposite pole attraction, and the movement of the vibration plane 12 is realized through the mounting bracket 33.

[0026] As can be further explained, the first magnetic block 322 and the second magnetic block 323 are both embedded inside 321. At the same time, the S pole of the first magnetic block 322 and the N pole of the second magnetic block 323 are both facing the center of the eccentric wheel 321. Therefore, it can be ensured that the eccentric wheel 321 can drive the N pole of the first magnetic block 322 and the S pole of the second magnetic block 323 to circulate through the bottom of the electromagnet 331 to achieve continuous vibration. The vibration frequency can be adjusted by the speed of the motor 31.

[0027] It is worth noting that the vibration degreasing unit 3 has two vibration transmission effects. One is the vibration effect achieved by direct contact between the eccentric wheel 321 and the mounting bracket 33, while the other is to energize the electromagnet 331 to achieve contactless vibration transmission, thereby reducing the noise of the equipment operation.

[0028] Furthermore, the mounting bracket 33 is fixedly installed at the bottom of the vibration plane 12, and a hinge bracket 34 is also installed inside the bottom shell 11. The hinge bracket 34 is also welded and fixed to the vibration plane 12. The hinge bracket 34 can restrict the vibration plane 12, so that the two sides of the vibration plane 12 can only swing.

[0029] As can be further explained, the electromagnet 331 is equipped with a shielding cover, and the bottom of the mounting bracket 33 is equipped with a shielding plate. The bottom of the electromagnet 331 passes through the mounting bracket 33 and the shielding plate in sequence. The shielding structure can effectively reduce the electromagnetic interference generated by the electromagnet 331 and avoid affecting the normal operation of other electronic components in the body of the fat-burning device 1.

[0030] According to the above structure, when the mounting brackets 33 installed on both sides of the bottom of the vibration plane 12 swing under the action of the rubber wheels, the user standing on the top of the vibration plane 12 will achieve vibration and fat loss under this alternating reciprocating motion.

[0031] It should be noted that both the bottom shell 11 and the vibration plane 12 are made of high-strength metal materials, which gives them sufficient structural strength to support the user's weight. This type of vibration transmission structure has been used to some extent in existing fat-burning devices, thus ensuring the generation of stable high-frequency vibration.

[0032] See attached document Figure 1 , Figure 2 and Figure 3 When the vibration fat-burning unit 3 drives the vibration plane 12 to vibrate the electrical conduction module 2, the user's motion state can be detected by the inertial measurement unit 13 installed inside the vibration plane 12, thereby determining the current working state of the vibration fat-burning device. The working state includes high-frequency vibration state, low-frequency vibration state, and standby state.

[0033] Specifically, the inertial measurement unit 13 can collect motion parameters such as acceleration and angular velocity of the vibration plane 12 in real time and transmit these data to the main control unit 14. The main control unit 14 has a built-in motion state recognition algorithm. By analyzing and processing the received motion parameters, it can accurately determine the current working state of the vibration fat-burning device.

[0034] It is worth noting that when the motion parameters show that the vibration plane 12 is in a high-frequency and large-amplitude reciprocating motion, it is determined to be a high-frequency vibration state. At this time, the power consumption control module 4 will control the electrical conduction module 2 to output electrical pulse signals at maximum power through the radio frequency microcurrent generator 6 to provide a stronger stimulation effect.

[0035] Specifically, when the motion parameters show that the vibration plane 12 is in a low-frequency and small-amplitude reciprocating motion, it is determined to be a low-frequency vibration state. The power consumption control module 4 reduces the output power of the radio frequency microcurrent generator 6 accordingly to save power and avoid over-stimulation.

[0036] When the motion parameters show that the vibration plane 12 has almost no motion, it is determined to be in standby mode. At this time, the power consumption control module 4 will control the electrical conduction module 2 to stop outputting electrical pulse signals through the radio frequency micro current generator 6 in order to extend the device's battery life. The radio frequency micro current generator 6 is used to generate low-frequency pulse current that acts on the human body.

[0037] See attached document Figures 2 to 7 The electrical conduction module 2 includes multiple conductive slides 25 and a multi-directional clamping mechanism 24. The multi-directional clamping mechanism 24 is vertically inserted on the substrate 22 and extends upward to the surface of the elastic insulating layer 21, so that the conductive slides 25 and the electrode head 23 can protrude to the top of the vibration plane 12 and abut against the user's foot, thereby forming an electrical conduction path.

[0038] To achieve the above objectives, a spring 26 is also installed inside the conductive through-hole protrusion 241. The top of the spring 26 extends upward into the interior of the conductive slide post 25 and is fixedly installed with the conductive slide post 25. Therefore, under the elastic action of the conductive slide post 25, the electrode head 23 can be driven to maintain contact with the user's foot, thereby greatly reducing the fluctuation of contact impedance and ensuring the stability of electrical conduction.

[0039] Based on this, the bottom of the conductive through-hole protrusion 241 of the multi-directional clamping mechanism 24 is electrically connected to the radio frequency microcurrent generator 6, so that the low-frequency pulse current generated by the radio frequency microcurrent generator 6 can be conducted to the human body through the multi-directional clamping mechanism 24, the conductive slide 25 and the electrode head 23. There are multiple conductive through-hole protrusions 241, conductive slide 25 and electrode head 23 respectively. The bottom of the conductive through-hole protrusion 241 is equipped with a terminal 244. Multiple terminals 244 can be connected in series by conductive wires, and the other end of the conductive wires is electrically connected to the output terminal of the radio frequency microcurrent generator 6.

[0040] As further explained, a conductive slip ring 242 is integrally formed inside the conductive through-hole protrusion 241. Corresponding to the conductive slip ring 242, an annular groove is formed on the surface of the conductive slip post 25. The conductive slip ring 242 slides in conjunction with the annular groove, thereby limiting the stroke of the spring 26 pushing the conductive slip post 25 and the electrode head 23 to move vertically. The stroke of the conductive slip post 25 and the electrode head 23 should be controlled within ±1.5cm.

[0041] See attached document Figure 6 and Figure 8 The electrode head 23 installed on the top of the conductive slide 25 is composed of a conductive layer 231, a buffer layer 232 and a contact layer 233. The conductive layer 231 is located in the inner layer and is made of a high-conductivity silicone material with a volume resistivity of less than 5Ω / cm.

[0042] Furthermore, the buffer layer 232 is located in the middle layer. It is made of silicone rubber with a microporous foam structure and the pore size should be controlled between 50-200μm. It is used to absorb vibration and shock and to accommodate sweat secreted by the skin to prevent sweat from accumulating and causing short circuits.

[0043] Specifically, silicone rubber has excellent elasticity and resistance to high and low temperatures, making it very suitable as a cushioning substrate. Through physical or chemical foaming processes (such as supercritical CO2 foaming technology), a uniform microporous structure is formed inside the silicone rubber, which enables it to effectively deform under pressure, absorb mechanical vibration, and avoid energy transfer loss.

[0044] Furthermore, the contact layer 233 is located on the outer layer and can be made of skin-friendly conductive silicone or conductive hydrogel. Its surface can be provided with anti-slip texture, the contact resistance is less than 100Ω, and it has skin-friendly characteristics to prevent skin discomfort caused by prolonged use.

[0045] Specifically, hydrogels have excellent biocompatibility and skin conformity, and can form a close fit with the microscopic uneven surface of the skin, greatly reducing contact resistance and motion artifacts. Their water-containing properties can provide a path similar to ion conduction, ensuring the stability of electrical conduction, while also being gentler on the skin.

[0046] In summary, the electrode head 23, which is composed of conductive layer 231, buffer layer 232 and contact layer 233, not only has high-efficiency electrical conduction performance, but also effectively absorbs vibration and shock, ensuring user comfort and safety during use, as well as the stability of electrical conduction.

[0047] See attached document Figures 4 to 7 Multiple snap-fit ​​protrusions 243 are arranged around the conductive through-hole protrusion 241, and multiple insertion grooves 245 adapted to the snap-fit ​​protrusions 243 are provided on the surface of the elastic insulating layer 21.

[0048] Specifically, since the elastic insulating layer 21 can be supported by thermoplastic vulcanized rubber, it can have good elasticity while being insulating, ensuring that the snap-fit ​​protrusion 243 can be snapped into the inside of the recess 245 under the deformation of the elastic insulating layer 21.

[0049] According to the above structure, a guide surface 8 and a locking surface 9 are provided on the surface of the buckle protrusion 243, and an guide inclined surface 2451 and a limiting wall 2452 are provided inside the insertion groove 245. The guide inclined surface 2451 can cooperate with the guide surface 8 to guide the buckle protrusion 243 into the insertion groove 245. There is an angle between one end of the guide inclined surface 2451 and the limiting wall 2452, so that after the conductive through hole protrusion 241 is embedded in the insertion groove 245, it can be locked by the abutment of the locking surface 9 and the limiting wall 2452. At the same time, the multi-directional insertion mechanism 24 is limited in multiple directions by multiple buckle protrusions 243 and multiple grooves located inside the insertion groove 245.

[0050] It is worth noting that by forming complementary pressing in multiple directions through the conductive through-hole protrusions 241 and the locating grooves 245, the relative displacement between the multi-directional locating mechanism 24, the elastic insulating layer 21, and the substrate 22 can be limited when the electrical conduction module 2 vibrates, avoiding contact offset caused by high-frequency vibration, ensuring that the electrical pulse signal can be stably transmitted to the human body, and improving the electrotherapy effect. At the same time, the multi-directional limiting design also enhances the overall mechanical stability of the device and facilitates overall assembly and disassembly.

[0051] As can be further explained, multiple electrical conduction modules 2 are evenly arranged on the top of the vibration plane 12 to simulate the characteristics of the foot. Between the multiple electrical conduction modules 2, a heating module 7 is embedded inside the elastic insulating layer 21. The setting of the heating module 7 can ensure that the user's feet feel a suitable temperature when the fat-burning device is used in a low-temperature environment, thus improving the comfort of use.

[0052] Please refer to the appendix for details. Figure 14 and Figure 15The heating module 7 uses a flexible substrate 71 as the base layer, which is covered with a thermally conductive insulating layer 72, which can effectively prevent current leakage while ensuring that heat can be conducted evenly.

[0053] Furthermore, a heating resistance wire 73 with a serpentine winding wire path design is provided between the flexible substrate 71 and the thermally conductive insulating layer 72. The serpentine winding wire path design not only increases the heating area, but also makes the heat distribution more uniform, avoiding the occurrence of local overheating.

[0054] Furthermore, once the device is started, it can quickly generate heat through the heating resistance wire 73 and transfer it to the user's feet through the thermally conductive insulation layer 72. In addition, the thermally conductive insulation layer 72 can be made of thermally conductive silicone rubber to ensure that a certain amount of contact is maintained during vibration, thereby maintaining stable heat exchange and further improving the performance of the vibration fat-burning device.

[0055] In another preferred embodiment: This embodiment is an optimization based on the embodiment of the fitness vibration fat-burning device system, and provides an electrical conduction stability control method, such as... Figure 2 and Figures 10 to 13 As shown.

[0056] The real-time output parameters of the electrical conduction module 2 are obtained. The output parameters include the operating current and the operating voltage. By obtaining the deviation value of the operating current from the preset standard current and the ripple coefficient of the operating voltage, the current output stability evaluation value can be determined based on the deviation value of the current and the ripple coefficient.

[0057] The stability assessment value consists of deviation calculation and weight fusion.

[0058] Deviation calculation includes current deviation: comparing the real-time current with a preset standard reference current inside the device. The larger the deviation (i.e., the more drastic the current fluctuation), the lower the score.

[0059] Voltage ripple coefficient: This is calculated by analyzing the smoothness of the voltage waveform and the ratio of the peak value to the average value of the voltage within a period (i.e., the ripple coefficient). The larger the ratio, the lower the score.

[0060] Weighted fusion involves combining the two dimensions (current stability and ripple coefficient) according to preset weights. For example: If the equipment is more susceptible to current surges, the current deviation accounts for 70% of the weight, and the ripple coefficient accounts for 30%. Conversely, if the equipment is more susceptible to voltage fluctuations, the ripple coefficient accounts for 70% of the weight, and the current deviation accounts for 30%. A normalized value (e.g., between 0 and 1) is obtained to form a stability assessment value. This weighting can more accurately reflect the output stability requirements of the equipment under different operating conditions.

[0061] Specifically, the stability assessment value of the current output can be used to determine whether adjustment is needed. If the assessment value is lower than the preset threshold, it indicates that the output stability is insufficient and the adjustment mechanism needs to be activated.

[0062] The control mechanism includes adjusting the output power of the radio frequency microcurrent generator 6. Specifically, when the current deviation is large, the output power of the radio frequency microcurrent generator 6 is appropriately reduced to reduce current fluctuations. When the voltage ripple coefficient is large, the voltage ripple is reduced and the smoothness of the output voltage is improved through power consumption optimization.

[0063] Furthermore, the current working state of the vibration fat-removing unit 3 can be obtained through the inertial measurement unit 13, wherein the working state of the vibration fat-removing unit 3 is one of high-frequency vibration state, low-frequency vibration state, and standby state.

[0064] Furthermore, the power consumption mode of the wireless communication module in the main control unit 14 can be dynamically adjusted based on the electrical conduction stability assessment value and the working status of the vibration degreasing unit 3.

[0065] If the electrical conduction stability assessment value is lower than the first preset threshold, the power consumption control module 4 controls the wireless communication module to switch from high power consumption mode to low power consumption mode. If the electrical conduction stability assessment value continues to be lower than the second preset threshold and the vibration fat-removing unit 3 is in a high-frequency vibration state, the power consumption control module 4 controls the wireless communication module to switch from low power mode to deep sleep mode.

[0066] Combining the above control methods, the following specific control flow is obtained and applied to the following scenarios: The standard operating current reference value of the electrical conduction module 2 is set to 500mA, the maximum allowable voltage ripple coefficient is 5%, and the electrical conduction stability evaluation value is represented by a value between 0 and 1. The higher the value, the more stable the electrical conduction. The first preset threshold is set to 0.80, and the second preset threshold is set to 0.60.

[0067] Normal steady state: When the user starts using the fat-burning device, the vibrating fat-burning unit 3 operates at a frequency of 20Hz (medium to low intensity), while the wireless communication module in the main control unit 14 is in high power consumption mode, synchronizing motion data with an external terminal (mobile APP).

[0068] At this time, the electrical conduction stability monitoring module 5 monitors in real time and obtains the following: the current operating current is 495mA and the voltage ripple coefficient is 2%. After weighted fusion, the generated electrical conduction stability evaluation value is 0.95.

[0069] Since the evaluation value of 0.95 is higher than the first preset threshold of 0.80, the power consumption control module 4 determines that the electrical conduction state is good, and the wireless communication module continues to work in the current high power consumption mode.

[0070] Slight fluctuations trigger low-power mode: As the wireless communication module in the main control unit 14 continues to operate at high power consumption, a slight disturbance occurs in the power supply current. The electrical conduction stability monitoring module 5 detects that the current operating current drops to 480mA and the voltage ripple coefficient rises to 3%. After weighted fusion, an electrical conduction stability evaluation value of 0.68 is generated.

[0071] The evaluation value of 0.68 is lower than the first preset threshold of 0.80. The power consumption control module 4 immediately switches the wireless communication module in the main control unit 14 from high power consumption mode to low power consumption mode (non-continuous reception mode, the listening interval is extended to 1 second). After the switch, the power supply load is reduced and the electrical conduction stability is improved.

[0072] Severe fluctuations trigger deep sleep mode: When the user increases the vibration intensity to 40Hz (high-frequency vibration), the overall power consumption of the device increases significantly. The electrical conduction stability monitoring module 5 detects that the current operating current fluctuates to 550mA and the voltage ripple coefficient increases to 6%. After weighted fusion, the electrical conduction stability assessment value is 0.35.

[0073] The evaluation value of 0.35 is not only lower than the first preset threshold of 0.80, but also lower than the second preset threshold of 0.60. At the same time, the vibration fat-burning unit 3 is in a 40Hz high-frequency vibration state. The power consumption control module 4 immediately forces the wireless communication module to enter a deep sleep mode and cuts off all power supply except for the real-time clock. After switching, the power supply of the electrical conduction module 2 is completely pure, ensuring the stability of electrical conduction.

[0074] It is worth noting that when the inertial measurement unit 13 detects a decrease in acceleration amplitude and determines that the user's movement is approaching stillness, the power consumption control module 4 obtains through the main control unit 14 that the vibration fat-burning unit 3 is about to stop operating. 500 milliseconds before the vibration fat-burning unit 3 stops, the power consumption control module 4 can send a wake-up signal to the wireless communication module which is in deep sleep mode, so that it enters low power mode and starts listening. When the vibration fat-burning unit 3 completely stops, the electrical conduction module 2 also stops working. The wireless communication module uses the no-load window period to synchronize data and upload the current exercise data to the external terminal (mobile APP).

[0075] See attached document Figure 1 , Figure 2 and Figure 10The main control unit 14 is equipped with a muscle fatigue monitoring module 15, which is electrically connected to the power consumption control module 4. This allows the power consumption control module 4 to read the muscle fatigue assessment value. When the muscle fatigue value exceeds the standard, the electrical conduction module will be shut down or its power will be reduced. The power consumption control module can determine that "the electrical conduction load is reduced and the power supply pressure is reduced, so the wireless module can be woken up in advance for data synchronization." Conversely, if the muscle condition is good, the electrical conduction module will work at full load, and the power consumption control module will continue to maintain the low power consumption state of the wireless module to save power.

[0076] Furthermore, the muscle fatigue monitoring module 15 is used to collect the user's muscle physiological signals and generate a muscle fatigue assessment value based on the muscle physiological signals.

[0077] In a preferred embodiment, the muscle fatigue monitoring module 15 includes a surface electromyography (EMG) sensor attached to the skin surface of the user's target muscle group (such as the abdomen, thigh, etc.) for real-time acquisition of surface EMG signals during use.

[0078] Specifically, the muscle fatigue monitoring module 15 has a built-in fatigue detection algorithm that preprocesses the collected surface electromyography signals (including amplification, filtering, and analog-to-digital conversion), extracts feature parameters (such as the root mean square value of time-domain features and the average power frequency of frequency-domain features), and generates a muscle fatigue assessment value based on these feature parameters.

[0079] Specifically, the assessment value can be a binary result (fatigue / non-fatigue) or a continuous fatigue index (such as 0-100%) to characterize the current degree of muscle fatigue. Based on the muscle fatigue assessment value, the power of the radio frequency microcurrent generator 6 is dynamically adjusted by the power consumption control module 4 to achieve dynamic control of electrical conduction power, while also protecting the user's muscles and preventing injury.

[0080] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
