Description
Technical Field
[0001] This application relates to the field of beauty device control technology, and in particular to an adaptive fitting control method and module for a rotatable multifunctional beauty device. Background Technology
[0002] Existing rotatable beauty devices generally suffer from technical problems during skin care, including inaccurate contact detection, insufficient adaptability of functional modes to the treatment area, and a simplistic safety control mechanism. Traditional techniques typically employ a fixed power output mode, failing to dynamically adjust operating parameters based on the actual contact pressure between the contact head and the skin, or the rotation angle. This can easily lead to the following defects: 1. Misjudgment of bonding status: Relying solely on a single sensor (such as a pressure sensor) to determine the bonding status without considering the rotation angle of the contact head may lead to false contact or continued operation even when the bonding is invalid due to angular deviation, resulting in energy waste and safety hazards. 2. Poor site adaptability: It cannot automatically identify and match the corresponding energy parameters according to the curvature differences of different beauty sites (such as the corners of the eyes, the wings of the nose, the cheeks, etc.). Users need to manually switch modes, which is cumbersome and the treatment effect is easily affected by improper parameter settings. 3. Lack of dynamic safety adjustment: It lacks a dynamic power adjustment mechanism based on real-time pressure and angle. When the contact pressure is too high or the rotation angle exceeds the safe range, it cannot reduce the energy output in time, which may cause skin damage. 4. Limitations in data interaction: Traditional beauty devices mostly rely on locally preset parameters, making it impossible to update personalized care plans in real time with mobile terminals, thus failing to meet the diverse needs of different users.
[0003] Therefore, a method is urgently needed to solve at least one of the above problems. Summary of the Invention
[0004] This application provides an adaptive fitting control method and device for a rotatable multifunctional beauty device, aiming to solve the technical problems commonly found in existing rotatable beauty devices during skin care, such as inaccurate fitting status detection, insufficient adaptability of functional modes to beauty areas, and a single safety control mechanism.
[0005] In a first aspect, embodiments of this application provide an adaptive fitting control method for a rotatable multifunctional beauty device. The rotatable multifunctional beauty device includes a main body and a contact head. The contact head is connected to the main body via a connecting structure. The contact head integrates a laser component for emitting red light and an electrode for outputting microcurrent. The method includes: The system acquires the rotation angle data and contact pressure data corresponding to the contact head; it compares the contact pressure data with a preset adhesion threshold. When the contact pressure data is greater than the adhesion threshold, it determines that the contact head is effectively in contact with the skin and triggers the corresponding laser component and electrode to start; when the contact pressure is lower than the adhesion threshold, it determines that the contact head is not effectively in contact with the skin or has detached from the skin, and controls the laser component and electrode to stop working. The real-time rotation angle data is compared with the pre-stored rotation angle range of each beauty part to determine the target beauty part that the contact head is currently acting on and the unique laser power range and microcurrent range corresponding to each target beauty part. Based on the matched target cosmetic area, the corresponding laser power range and microcurrent range are obtained from the mobile terminal, and dynamically adjusted in conjunction with real-time contact pressure data: if the contact pressure exceeds the safe pressure threshold of the target cosmetic area, the laser power is reduced to the minimum safe power corresponding to the target cosmetic area, and the microcurrent is reduced to the minimum safe current corresponding to the target cosmetic area; if the rotation angle exceeds the rotation angle range of the target cosmetic area, the laser power is adjusted to the minimum safe power corresponding to the target cosmetic area, and the microcurrent is kept within the safe current range of the target cosmetic area.
[0006] In some embodiments, the connection structure employs a magnetic sealing ring; after maintaining the microcurrent within the safe current range of the target cosmetic area, the method further includes: monitoring contact pressure and rotation angle data; issuing an alarm and stopping the laser component and electrode output when the contact pressure continuously exceeds the safe pressure threshold for a first preset time, or the rotation angle continuously exceeds the rotation angle range for a second preset time; stopping the output and resetting the laser power and microcurrent to their initial state when the contact pressure is lower than the adhesion threshold; calculating the contact head rotation amplitude based on angle sensor data, and dynamically adjusting the sealing pressure in conjunction with the deformation parameters of the magnetic sealing ring to ensure that liquid cannot penetrate into the sealed cavity formed by the lower shell of the main body, the head liner, the lower shell of the head, and the upper shell of the main body.
[0007] In some embodiments, acquiring the rotation angle data and contact pressure data corresponding to the contact head includes: acquiring the rotation angle data of the contact head in real time through an angle sensor disposed within the connection structure, acquiring the contact pressure data in real time through a pressure sensor integrated on the contact surface between the contact head and the skin, and synchronously transmitting the acquired rotation angle data and contact pressure data to the control module of the beauty device for processing.
[0008] In some embodiments, determining that the contact head is effectively in contact with the skin when the contact pressure data is greater than the adhesion threshold and triggering the corresponding laser component and electrode to start includes: filtering the contact pressure data and comparing it with a preset adhesion threshold; if the results of three consecutive samplings are all greater than the adhesion threshold and the sampling time interval does not exceed 50 milliseconds, then determining that the contact head is effectively in contact with the skin, sending a start signal to the drive circuit of the laser component and the power management module of the electrode to trigger the laser component and electrode to start.
[0009] In some embodiments, the step of comparing the real-time rotation angle data with the pre-stored rotation angle ranges of each cosmetic part to determine the target cosmetic part currently being acted upon by the contact head and the unique laser power range and microcurrent range corresponding to each target cosmetic part includes: pre-storing a mapping table of rotation angle ranges, laser power ranges, and microcurrent ranges corresponding to each cosmetic part; traversing the rotation angle ranges of each cosmetic part in the mapping table in a preset order; comparing the real-time rotation angle data with the currently traversed rotation angle range; if the real-time rotation angle data falls within the rotation angle range, then determining the cosmetic part corresponding to that range as the target cosmetic part, and retrieving the corresponding laser power range and microcurrent range; if multiple rotation angle ranges match, selecting the cosmetic part with higher angle range accuracy as the target cosmetic part.
[0010] In some embodiments, obtaining the corresponding laser power range and microcurrent range from the mobile terminal based on the matched target cosmetic area includes: sending the identification information of the target cosmetic area to the mobile terminal via a Bluetooth communication module; the mobile terminal retrieving the corresponding laser power range and microcurrent range from its database based on the identification information and transmitting it back to the control module via the Bluetooth communication module; after receiving the transmitted data, comparing the transmitted data with the locally pre-stored default laser power range and microcurrent range; if there is a difference, updating the local data with the data transmitted back by the mobile terminal.
[0011] In some embodiments, the dynamic adjustment based on real-time contact pressure data includes: calculating the difference between the real-time contact pressure data and the safe pressure threshold of the target cosmetic area; determining the corresponding adjustment coefficient according to a preset pressure-adjustment coefficient mapping relationship; and linearly adjusting the current laser power and microcurrent according to the adjustment coefficient. If the difference is positive and gradually increases, the laser power and microcurrent are reduced proportionally. If the difference is negative and gradually decreases, the laser power and microcurrent are increased proportionally, but neither exceeds the laser power range and microcurrent range corresponding to the target cosmetic area.
[0012] In some embodiments, reducing the laser power to the minimum safe power corresponding to the target cosmetic area and reducing the microcurrent to the minimum safe current corresponding to the target cosmetic area includes: retrieving the minimum safe power value and the minimum safe current value corresponding to the target cosmetic area from the memory; adjusting the drive current of the laser component through a pulse width modulation signal to stabilize the laser power at the minimum safe power value; stabilizing the microcurrent at the minimum safe current value by adjusting the voltage output of the electrode drive circuit; and continuously monitoring the real-time values of the laser power and microcurrent to ensure that they are not lower than the corresponding minimum safe values.
[0013] In some embodiments, if the rotation angle exceeds the rotation angle range of the target cosmetic area, adjusting the laser power to the minimum safe power corresponding to the target cosmetic area and maintaining the microcurrent within the safe current range of the target cosmetic area includes: real-time monitoring of rotation angle data; when the rotation angle is detected to exceed the upper or lower limit of the rotation angle range of the target cosmetic area, immediately sending a minimum safe power control signal to the drive circuit of the laser component to quickly adjust the laser power to the minimum safe power corresponding to the target cosmetic area; and activating a closed-loop control mechanism for the microcurrent to maintain the microcurrent within the safe current range of the target cosmetic area through feedback adjustment until the rotation angle returns to the rotation angle range of the target cosmetic area.
[0014] Secondly, embodiments of this application provide a control module for implementing the method provided in any embodiment of this application.
[0015] The method provided in this application embodiment can accurately identify the effective contact state by synchronously acquiring the rotation angle data and contact pressure data of the contact head, combined with a dual judgment mechanism (pressure threshold and angle range), avoiding false start or missed start, and improving the effectiveness and safety of energy output. Based on the pre-stored mapping relationship between the rotation angle range of each beauty area and the energy parameters, it can automatically match the unique laser power and microcurrent range of the current treatment area, achieving precise "area-parameter" matching, reducing manual operation by users and improving the treatment effect. By monitoring pressure and angle in real time, combined with safety thresholds and dynamic adjustment strategies (such as power degradation and current closed-loop control), it can respond quickly under abnormal conditions, prevent skin damage caused by excessive pressure or angle deviation, and strengthen the safety protection mechanism. Through data interaction with mobile terminals, the energy parameter range can be updated in real time, supporting dynamic adjustment of personalized care plans and enhancing the adaptability of the equipment and user experience. By incorporating mechanical structures such as magnetic sealing rings into the control algorithm, structural deformation parameters (such as dynamic adjustment of sealing pressure) are integrated to achieve coordinated optimization of control logic and hardware structure, thereby improving the reliability and sealing performance of the equipment.

[0025] Existing rotatable beauty devices generally suffer from technical problems during skin care, including inaccurate contact detection, insufficient adaptability of functional modes to the treatment area, and a simplistic safety control mechanism. Traditional techniques typically employ a fixed power output mode, failing to dynamically adjust operating parameters based on the actual contact pressure between the contact head and the skin, or the rotation angle. This can easily lead to the following defects: 1. Misjudgment of bonding status: Relying solely on a single sensor (such as a pressure sensor) to determine the bonding status without considering the rotation angle of the contact head may lead to false contact or continued operation even when the bonding is invalid due to angular deviation, resulting in energy waste and safety hazards. 2. Poor site adaptability: It cannot automatically identify and match the corresponding energy parameters according to the curvature differences of different beauty sites (such as the corners of the eyes, the wings of the nose, the cheeks, etc.). Users need to manually switch modes, which is cumbersome and the treatment effect is easily affected by improper parameter settings. 3. Lack of dynamic safety adjustment: It lacks a dynamic power adjustment mechanism based on real-time pressure and angle. When the contact pressure is too high or the rotation angle exceeds the safe range, it cannot reduce the energy output in time, which may cause skin damage. 4. Limitations of data interaction: Traditional beauty devices rely heavily on local preset parameters and cannot be linked with mobile terminals in real time to update personalized care plans, making it difficult to meet the differentiated needs of different users.
[0026] Currently, no existing technology discloses a solution that integrates rotation angle and contact pressure for the application of beauty devices in terms of fit control, part recognition, and dynamic safety adjustment, nor does it involve a mechanism for dynamically updating parameters by combining mobile terminal data.
[0027] To solve the above problem, please refer to Figure 1 This application provides an adaptive fitting control method for a rotatable multifunctional beauty device, applied to the control module of the rotatable multifunctional beauty device.
[0028] For example, such as Figure 2 and Figure 3As shown, the rotatable multifunctional beauty device includes a main body 200 and a contact head 100. The contact head is connected to the main body through a connecting structure. The contact head integrates a laser component for emitting red light and an electrode for outputting microcurrent.
[0029] Specifically, such as Figure 1 As shown, the adaptive fitting control method for the provided rotatable multifunctional beauty device includes steps S101 to S103. Details are as follows: Step S101. Obtain the rotation angle data and contact pressure data corresponding to the contact head; compare the contact pressure data with the preset adhesion threshold. When the contact pressure data is greater than the adhesion threshold, it is determined that the contact head is effectively in contact with the skin, and the corresponding laser component and electrode are triggered to start; when the contact pressure is lower than the adhesion threshold, it is determined that it is not effectively in contact with the skin or has detached from the skin, and the laser component and electrode are controlled to stop working.
[0030] Specifically, the core of this step is to solve the problem of "misjudgment of adhesion status". By integrating two types of data, contact pressure and rotation angle, it can more accurately determine whether the device is effectively in contact with the skin, and use this as the "master switch" to start and stop the device's energy output (laser and microcurrent).
[0031] Contact pressure data: Acquired in real time by pressure sensors (such as thin-film pressure sensors, strain gauges, etc.) installed at the contact head or connecting structure. Acquired in real time by angle sensors (such as Hall sensors, photoelectric encoders, etc.) installed at the rotation shaft of the connecting structure.
[0032] The control module compares the real-time contact pressure data with a preset adhesion threshold. Only when the detected pressure exceeds this threshold does the system determine that the contact head has formed an effective and tight fit with the skin. At this point, the control module triggers a signal to activate the laser component to emit red light, and the electrodes begin to output a microcurrent.
[0033] During operation, the device continuously monitors pressure data. Once the pressure value is detected to be below the adhesion threshold (for example, when the user lifts the beauty device off the skin, or the adhesion becomes loose), the control module will immediately determine that it is "ineffectively adhered" or "detached" and quickly cut off the output of laser and microcurrent, causing the device to stop working.
[0034] This design avoids false triggering caused by angular deviations that can occur with traditional single-sensor systems, ensuring that energy is released only when in actual contact with the skin. It prevents the device from idling during ineffective contact (such as in mid-air), saving energy and eliminating potential safety risks caused by misoperation.
[0035] Step S102. Compare the real-time rotation angle data with the pre-stored rotation angle ranges of each cosmetic part to determine the target cosmetic part currently being acted upon by the contact head and the unique laser power range and microcurrent range corresponding to each target cosmetic part.
[0036] Specifically, this step aims to address the issue of "poor site compatibility." The principle is based on the characteristic rotation angle of the contact head caused by different facial features (such as flat cheeks, curved nose wings, and sunken corners of the eyes). By comparing the real-time angle with a pre-stored angle "map," the system automatically identifies the area being treated and retrieves the corresponding safe and effective energy parameter range for that area.
[0037] During the development phase, an ergonomic database was established through extensive experimentation and data collection. This database pre-stores the typical rotation angle ranges for various cosmetic areas (such as the forehead, left and right cheeks, nostrils, upper and lower eyelids, perioral area, and neck). For example, when treating the nostrils, the contact head may have a larger inward tilt angle; when treating the corners of the eyes, it may have a more subtle adjustment angle.
[0038] After confirming effective fit in step S101, the control module reads the real-time rotation angle data. This real-time angle value is compared one by one with the rotation angle ranges of all parts pre-stored in the database. When the real-time angle falls within the preset angle range of a certain part, that part is determined to be the target cosmetic area for the current treatment.
[0039] The system then automatically locks onto the unique laser power and microcurrent range corresponding to the target cosmetic area. These ranges are optimal and safe parameter intervals set based on factors such as the thickness and sensitivity of the skin in different areas.
[0040] Users don't need to manually switch modes; the beauty device automatically "knows" which area is being treated and prepares the corresponding "treatment plan," greatly simplifying the operation process. This ensures a high degree of compatibility between energy parameters and the treated area, improving the effectiveness and comfort of the treatment.
[0041] Step S103. Based on the matched target cosmetic area, obtain the corresponding laser power range and microcurrent range from the mobile terminal, and dynamically adjust them in conjunction with real-time contact pressure data: if the contact pressure exceeds the safe pressure threshold of the target cosmetic area, reduce the laser power to the minimum safe power corresponding to the target cosmetic area, and at the same time reduce the microcurrent to the minimum safe current corresponding to the target cosmetic area; if the rotation angle exceeds the rotation angle range of the target cosmetic area, adjust the laser power to the minimum safe power corresponding to the target cosmetic area, and keep the microcurrent within the safe current range of the target cosmetic area.
[0042] Specifically, this step comprehensively addresses the issues of "lack of dynamic safety adjustment" and "limitations in data interaction." Based on the identification of the location in step S102, it introduces real-time contact pressure as a dynamic adjustment variable and interacts with a mobile terminal (such as a mobile app) to achieve power and current adjustment and personalized scheme updates based on real-time status.
[0043] The control module connects to the user's mobile app via a wireless communication module (such as Bluetooth). Based on the identified target cosmetic area, it obtains a more personalized laser power range and microcurrent range for that area from the mobile app. These parameters can be set by the user, recommended by experts, or generated by cloud-based AI algorithms based on the user's historical data, enabling dynamic updates and personalization of the parameters.
[0044] The system continuously monitors real-time contact pressure. Each target cosmetic area has a preset safe pressure threshold in the parameters sent to the mobile terminal. If the detected real-time pressure exceeds this safe threshold (meaning the user is applying too much pressure), the control module immediately takes protective measures: forcibly reducing the laser power to the minimum safe power corresponding to that area, and simultaneously reducing the microcurrent to the minimum safe current corresponding to that area. This effectively avoids potential physical or thermal damage to skin tissue caused by excessive pressure.
[0045] The system simultaneously monitors the real-time rotation angle. If the rotation angle exceeds the preset safe angle range for the target cosmetic area (meaning the instrument may have slipped onto an unsuitable area or the operating posture is incorrect), the control module will adjust the laser power to the minimum safe power and ensure that the microcurrent output remains within its safe current range. This is a preventative protection against the misuse of high energy in non-target areas.
[0046] This achieves a safety upgrade from "passive response" to "proactive prevention," dynamically adjusting energy output based on real-time data to maximize skin protection. Through integration with mobile devices, it breaks the limitations of fixed parameters in traditional beauty devices, allowing for readily updated and up-to-date skincare plans to truly meet the diverse needs of different users.
[0047] In some embodiments, the connection structure employs a magnetic sealing ring; after maintaining the microcurrent within the safe current range of the target cosmetic area, the method further includes: monitoring contact pressure and rotation angle data; issuing an alarm and stopping the laser component and electrode output when the contact pressure continuously exceeds the safe pressure threshold for a first preset time, or the rotation angle continuously exceeds the rotation angle range for a second preset time; stopping the output and resetting the laser power and microcurrent to their initial state when the contact pressure is lower than the adhesion threshold; calculating the contact head rotation amplitude based on angle sensor data, and dynamically adjusting the sealing pressure in conjunction with the deformation parameters of the magnetic sealing ring to ensure that liquid cannot penetrate into the sealed cavity formed by the lower shell of the main body, the head liner, the lower shell of the head, and the upper shell of the main body.
[0048] If an unsafe condition (excessive pressure or abnormal angle) persists for a period of time, stronger protective measures should be taken. Once the device is removed from the skin, the energy output parameters should be reset to prepare for the next use.
[0049] By dynamically adjusting the pressure of the magnetic sealing ring using sensor data, the waterproof and leak-proof performance is improved.
[0050] The system is set with two timers: one for monitoring pressure exceeding the limit (first preset time, such as 3 seconds), and the other for monitoring angle exceeding the limit (second preset time, such as 2 seconds).
[0051] When the contact pressure continuously exceeds the safety pressure threshold for a first preset time, or the rotation angle continuously exceeds the rotation angle range for a second preset time, the control module will issue an alarm to the user via a buzzer or vibration motor and completely stop the laser and microcurrent output.
[0052] When the contact pressure is detected to be below the adhesion threshold (indicating that the device has left the skin), the control module will not only stop outputting, but also reset the currently set laser power and microcurrent value to the initial default state (such as zero or a very low standby value) to ensure that the next adhesion start-up begins from a safe and uniform starting point.
[0053] The control module calculates the real-time rotation amplitude of the contact head based on data from the angle sensor. Based on this rotation amplitude, and combined with pre-stored deformation parameters of the magnetic sealing ring (such as the relationship curve between magnetic force and clearance), an algorithm calculates the ideal sealing pressure required at that moment.
[0054] Subsequently, the actual clamping force of the sealing ring is dynamically adjusted by regulating the electromagnet that controls the magnetic attraction (if supported) or by utilizing the design of the mechanical structure. This maintains an optimal seal during rotation, effectively preventing beauty fluids or moisture from seeping into the sealed cavity formed by the lower shell of the main body, the head liner, the lower shell of the head, and the upper shell of the main body, thus protecting the delicate electronic components.
[0055] In some embodiments, acquiring the rotation angle data and contact pressure data corresponding to the contact head includes: acquiring the rotation angle data of the contact head in real time through an angle sensor disposed within the connection structure, acquiring the contact pressure data in real time through a pressure sensor integrated on the contact surface between the contact head and the skin, and synchronously transmitting the acquired rotation angle data and contact pressure data to the control module of the beauty device for processing.
[0056] This embodiment clarifies the specific acquisition location, method, and transmission path for rotation angle data and contact pressure data.
[0057] An angle sensor (such as a Hall sensor, which senses angle by detecting changes in the magnetic field) is directly installed inside the magnetically attracted rotating connection structure to accurately and directly measure the rotation angle of the contact head relative to the body.
[0058] Integrate pressure sensors (such as thin-film or capacitive pressure sensor arrays) onto the surface of the contact head that directly contacts the skin to obtain the most accurate pressure data.
[0059] After collecting data, the two sensors transmit the data synchronously and in real time to the core control module (such as MCU) of the beauty device through internal circuits (such as I2C or SPI bus) for subsequent analysis and processing.
[0060] In some embodiments, determining that the contact head is effectively in contact with the skin when the contact pressure data is greater than the adhesion threshold and triggering the corresponding laser component and electrode to start includes: filtering the contact pressure data and comparing it with a preset adhesion threshold; if the results of three consecutive samplings are all greater than the adhesion threshold and the sampling time interval does not exceed 50 milliseconds, then determining that the contact head is effectively in contact with the skin, sending a start signal to the drive circuit of the laser component and the power management module of the electrode to trigger the laser component and electrode to start.
[0061] This embodiment provides a more robust fit determination and device startup logic, which prevents false startup caused by momentary jitter or interference through filtering and multiple consecutive confirmations.
[0062] The raw contact pressure data is digitally filtered (e.g., by moving average filtering) to eliminate noise and spikes.
[0063] The filtered pressure data needs to meet a strict composite condition to be activated: the values of three consecutive samples must all be greater than the fit threshold, and the time interval between these three samples must not exceed 50 milliseconds.
[0064] Only when the above conditions are met simultaneously will the control module determine that the connection is "effective" and then send a start signal to the drive circuit of the laser component and the power management module of the electrode to start the energy output.
[0065] In some embodiments, the step of comparing the real-time rotation angle data with the pre-stored rotation angle ranges of each cosmetic part to determine the target cosmetic part currently being acted upon by the contact head and the unique laser power range and microcurrent range corresponding to each target cosmetic part includes: pre-storing a mapping table of rotation angle ranges, laser power ranges, and microcurrent ranges corresponding to each cosmetic part; traversing the rotation angle ranges of each cosmetic part in the mapping table in a preset order; comparing the real-time rotation angle data with the currently traversed rotation angle range; if the real-time rotation angle data falls within the rotation angle range, then determining the cosmetic part corresponding to that range as the target cosmetic part, and retrieving the corresponding laser power range and microcurrent range; if multiple rotation angle ranges match, selecting the cosmetic part with higher angle range accuracy as the target cosmetic part.
[0066] This embodiment details how to identify body parts using a lookup table method and provides a solution when the identification results are ambiguous (matching multiple body parts).
[0067] A mapping table is pre-stored in the device's memory. This table establishes the correspondence between the cosmetic area (e.g., "left cheek") and its rotation angle range, laser power range, and microcurrent range. The control module traverses this mapping table according to a preset order (e.g., from the center of the face to the edge). It compares the real-time acquired rotation angle data with the rotation angle range of the currently traversed area. Once the real-time data falls within a certain range, that area is identified as the target cosmetic area, and its corresponding energy parameter range is retrieved.
[0068] If real-time angle data falls within the preset range of two or more locations simultaneously, the system will select the location with higher angle range accuracy (i.e., a narrower and more precise range) as the final target to improve the accuracy of recognition.
[0069] In some embodiments, obtaining the corresponding laser power range and microcurrent range from the mobile terminal based on the matched target cosmetic area includes: sending the identification information of the target cosmetic area to the mobile terminal via a Bluetooth communication module; the mobile terminal retrieving the corresponding laser power range and microcurrent range from its database based on the identification information and transmitting it back to the control module via the Bluetooth communication module; after receiving the transmitted data, comparing the transmitted data with the locally pre-stored default laser power range and microcurrent range; if there is a difference, updating the local data with the data transmitted back by the mobile terminal.
[0070] This embodiment describes in detail how the beauty device obtains the latest, personalized energy parameters from a mobile terminal (such as a mobile app) and handles potential data inconsistencies.
[0071] The beauty device sends a message to the paired mobile terminal via its Bluetooth communication module, which contains identification information (such as part ID) of the identified target beauty area.
[0072] After receiving the request, the mobile app retrieves the laser power range and microcurrent range customized for the user from its local database or cloud based on the identification information.
[0073] After receiving the data transmitted back from the mobile terminal, the beauty device will compare it with its own pre-stored default parameter range.
[0074] If the returned data differs from the local default data, the control module will prioritize using the data returned by the mobile terminal to update the current working parameters, ensuring that the user receives the latest and most personalized care plan.
[0075] In some embodiments, the dynamic adjustment based on real-time contact pressure data includes: calculating the difference between the real-time contact pressure data and the safe pressure threshold of the target cosmetic area; determining the corresponding adjustment coefficient according to a preset pressure-adjustment coefficient mapping relationship; and linearly adjusting the current laser power and microcurrent according to the adjustment coefficient. If the difference is positive and gradually increases, the laser power and microcurrent are reduced proportionally. If the difference is negative and gradually decreases, the laser power and microcurrent are increased proportionally, but neither exceeds the laser power range and microcurrent range corresponding to the target cosmetic area.
[0076] This embodiment provides a smoother, more refined dynamic adjustment strategy. Instead of abruptly switching to the lowest power only when the threshold is exceeded, it performs proportional linear adjustment based on the degree to which the pressure deviates from the safe threshold.
[0077] The difference between real-time contact pressure data and the safe pressure threshold of the target cosmetic area is calculated in real time.
[0078] Based on a preset pressure-regulation coefficient mapping relationship (which can be a formula or a lookup table), a corresponding regulation coefficient (usually between 0 and 1) is determined according to the current pressure difference.
[0079] If the difference is positive and gradually increases (pressure is increasing and far exceeding the safety limit): reduce the current laser power and microcurrent proportionally according to the adjustment coefficient. The larger the difference, the greater the reduction. If the difference is negative and gradually decreases (pressure is recovering from insufficient to the safety limit): increase the laser power and microcurrent proportionally according to the adjustment coefficient to help the energy output quickly recover to an effective level.
[0080] Throughout the entire linear adjustment process, the final power and current values must never exceed the upper and lower limits specified by the laser power range and microcurrent range corresponding to the target cosmetic area.
[0081] In some embodiments, reducing the laser power to the minimum safe power corresponding to the target cosmetic area and reducing the microcurrent to the minimum safe current corresponding to the target cosmetic area includes: retrieving the minimum safe power value and the minimum safe current value corresponding to the target cosmetic area from the memory; adjusting the drive current of the laser component through a pulse width modulation signal to stabilize the laser power at the minimum safe power value; stabilizing the microcurrent at the minimum safe current value by adjusting the voltage output of the electrode drive circuit; and continuously monitoring the real-time values of the laser power and microcurrent to ensure that they are not lower than the corresponding minimum safe values.
[0082] This embodiment illustrates in detail how to precisely control the laser power and microcurrent to their respective minimum safe values when a safety condition is triggered.
[0083] The minimum safe power and minimum safe current values corresponding to the target cosmetic area are read from memory. The drive current of the laser component is adjusted by generating a pulse width modulation signal with a specific duty cycle, thereby precisely stabilizing the output laser power at the minimum safe power value. The microcurrent flowing through the skin is precisely stabilized at the minimum safe current value by adjusting the voltage output of the electrode drive circuit.
[0084] During the period of maintaining the minimum safe output, the system continuously monitors the real-time values of laser power and microcurrent, and ensures that they do not fall below the corresponding minimum safe value through closed-loop feedback, thus ensuring both safety and maintaining a minimum level of care.
[0085] In some embodiments, if the rotation angle exceeds the rotation angle range of the target cosmetic area, adjusting the laser power to the minimum safe power corresponding to the target cosmetic area and maintaining the microcurrent within the safe current range of the target cosmetic area includes: real-time monitoring of rotation angle data; when the rotation angle is detected to exceed the upper or lower limit of the rotation angle range of the target cosmetic area, immediately sending a minimum safe power control signal to the drive circuit of the laser component to quickly adjust the laser power to the minimum safe power corresponding to the target cosmetic area; and activating a closed-loop control mechanism for the microcurrent to maintain the microcurrent within the safe current range of the target cosmetic area through feedback adjustment until the rotation angle returns to the rotation angle range of the target cosmetic area.
[0086] This embodiment refines the control strategy when the rotation angle exceeds the safe range, emphasizing rapid suppression of laser power and precise stabilization of microcurrent.
[0087] Once the rotation angle is detected to exceed the upper or lower limit of the rotation angle range of the current target cosmetic area, the control module will immediately send a hard-coded minimum safe power control signal to the drive circuit of the laser component, so that the laser power will drop rapidly and stabilize at the minimum safe power.
[0088] Simultaneously, the system activates a closed-loop control mechanism for the microcurrent. This mechanism compares the feedback signal of the output current in real time with the set safe current range and quickly adjusts the output of the electrode drive circuit to maintain the microcurrent within the safe current range of the current target cosmetic area, rather than simply reducing it to a minimum.
[0089] The aforementioned safety control status will continue until the system detects that the rotation angle has returned to the rotation angle range of the target cosmetic area.
[0090] In some embodiments, by introducing reinforcement learning algorithms, beauty devices can autonomously learn and optimize the best energy parameters for each user and each area through continuous "interaction" with the user's skin, thereby achieving truly personalized care.
[0091] The working process of the beauty device is modeled as a reinforcement learning problem, including: State: Combining real-time rotation angle, contact pressure, user skin type data (e.g., dry, oily, sensitive) obtained from the mobile terminal, and historical treatment data. Action: The control module fine-tunes the laser power and microcurrent within a safe range. Reward: After the treatment, the user is guided through a mobile app to rate the comfort and immediate effects of the treatment (e.g., 1-5 stars). Objective: To learn a strategy (i.e., parameter adjustment rules) that maximizes long-term user rewards.
[0092] During each treatment, the system records different state-action pairs. After the treatment, the user's rating is used as a reward signal and fed back to a local reinforcement learning model (such as a lightweight neural network or SARSA algorithm). The model updates its policy based on the reward. For example, if a user gives a five-star rating when a certain set of parameters is used under a specific combination of pressure and angle, the policy will be more inclined to choose this set of parameters when encountering similar situations in the future. After repeated use, the beauty device will "remember" the treatment method most suitable for the user, automatically finding the optimal balance between effectiveness and comfort without the need for repeated manual adjustments.
[0093] In some embodiments, a virtual model of the user's skin is created, and this model is driven by real-time data to achieve a "prediction" rather than a "post-event reaction" of the subcutaneous response.
[0094] A personalized digital twin model of the skin is created for each user on a mobile device or in the cloud. This model integrates the user's static data (age, skin type) and dynamic data (real-time contact pressure, rotation angle, energy output, and ambient temperature and humidity during the treatment).
[0095] During the treatment, the beauty device streams real-time data on contact pressure and rotation angle to a digital twin. Based on the received data, the digital twin simulates and calculates in real-time the energy deposition, temperature distribution, and physiological responses of the laser and microcurrent in the skin tissue.
[0096] The digital twin predicts whether the temperature of key skin areas (such as the dermis) will exceed a safe threshold within seconds. Once a potential risk is predicted, the digital twin immediately sends instructions to the beauty device to proactively reduce energy output or change its operating mode before the skin actually feels discomfort or damage, thus achieving a leap from "passive safety" to "proactive prevention".
[0097] In some embodiments, a federated learning framework allows multiple beauty devices to jointly train a more powerful global model, while all users' raw data remains local.
[0098] Each beauty device trains a local model using its users' data (anonymized rotation angles, pressure, final scores, etc.). Periodically, the beauty device uploads only the updated parameters of the local model (not the original data) to the cloud server in encrypted form.
[0099] The cloud server collects model parameters from a large number of devices and aggregates them into a smarter, more generalizable global model using algorithms (such as FedAvg). The updated global model is then distributed to all participating beauty devices.
[0100] In some embodiments, skin texture images captured by a miniature camera are fused together, and an attention mechanism is used to focus on key features to distinguish between extremely similar angular ranges.
[0101] A miniature, low-power camera is integrated at the edge of the contact head. During treatment, it simultaneously acquires rotation angle data and local skin images.
[0102] A lightweight convolutional neural network is used to extract features (such as pore distribution and fine line direction) from skin images. The image feature vector is then concatenated with rotation angle data to form a multimodal fusion feature vector.
[0103] The fused features are fed into a classification model that includes an attention layer. The attention mechanism automatically learns and assigns higher weights to features that are most important for distinguishing different areas (e.g., the unique texture at the corner of the eye).
[0104] The model ultimately outputs a probability distribution, providing the confidence level for each area being treated. The system selects the area with the highest confidence level as the target cosmetic area.
[0105] This method effectively solves the problem of overlapping angle ranges. For example, even if the user holds the camera at a similar angle to their cheek, but the camera captures obvious skin texture around the eyes, the system will decisively identify it as "skin around the eyes" rather than "cheek," thus applying gentler energy parameters.

[0112] In one embodiment, the processor is configured to run a computer program stored in memory to perform the following steps: The system acquires the rotation angle data and contact pressure data corresponding to the contact head; it compares the contact pressure data with a preset adhesion threshold. When the contact pressure data is greater than the adhesion threshold, it determines that the contact head is effectively in contact with the skin and triggers the corresponding laser component and electrode to start; when the contact pressure is lower than the adhesion threshold, it determines that the contact head is not effectively in contact with the skin or has detached from the skin, and controls the laser component and electrode to stop working. The real-time rotation angle data is compared with the pre-stored rotation angle range of each beauty part to determine the target beauty part that the contact head is currently acting on and the unique laser power range and microcurrent range corresponding to each target beauty part. Based on the matched target cosmetic area, the corresponding laser power range and microcurrent range are obtained from the mobile terminal, and dynamically adjusted in conjunction with real-time contact pressure data: if the contact pressure exceeds the safe pressure threshold of the target cosmetic area, the laser power is reduced to the minimum safe power corresponding to the target cosmetic area, and the microcurrent is reduced to the minimum safe current corresponding to the target cosmetic area; if the rotation angle exceeds the rotation angle range of the target cosmetic area, the laser power is adjusted to the minimum safe power corresponding to the target cosmetic area, and the microcurrent is kept within the safe current range of the target cosmetic area.

[0115] In some embodiments, determining that the contact head is effectively in contact with the skin when the contact pressure data is greater than the adhesion threshold and triggering the corresponding laser component and electrode to start includes: filtering the contact pressure data and comparing it with a preset adhesion threshold; if the results of three consecutive samplings are all greater than the adhesion threshold and the sampling time interval does not exceed 50 milliseconds, then determining that the contact head is effectively in contact with the skin, sending a start signal to the drive circuit of the laser component and the power management module of the electrode to trigger the laser component and electrode to start.
[0116] In some embodiments, the step of comparing the real-time rotation angle data with the pre-stored rotation angle ranges of each cosmetic part to determine the target cosmetic part currently being acted upon by the contact head and the unique laser power range and microcurrent range corresponding to each target cosmetic part includes: pre-storing a mapping table of rotation angle ranges, laser power ranges, and microcurrent ranges corresponding to each cosmetic part; traversing the rotation angle ranges of each cosmetic part in the mapping table in a preset order; comparing the real-time rotation angle data with the currently traversed rotation angle range; if the real-time rotation angle data falls within the rotation angle range, then determining the cosmetic part corresponding to that range as the target cosmetic part, and retrieving the corresponding laser power range and microcurrent range; if multiple rotation angle ranges match, selecting the cosmetic part with higher angle range accuracy as the target cosmetic part.
[0117] In some embodiments, obtaining the corresponding laser power range and microcurrent range from the mobile terminal based on the matched target cosmetic area includes: sending the identification information of the target cosmetic area to the mobile terminal via a Bluetooth communication module; the mobile terminal retrieving the corresponding laser power range and microcurrent range from its database based on the identification information and transmitting it back to the control module via the Bluetooth communication module; after receiving the transmitted data, comparing the transmitted data with the locally pre-stored default laser power range and microcurrent range; if there is a difference, updating the local data with the data transmitted back by the mobile terminal.
[0118] In some embodiments, the dynamic adjustment based on real-time contact pressure data includes: calculating the difference between the real-time contact pressure data and the safe pressure threshold of the target cosmetic area; determining the corresponding adjustment coefficient according to a preset pressure-adjustment coefficient mapping relationship; and linearly adjusting the current laser power and microcurrent according to the adjustment coefficient. If the difference is positive and gradually increases, the laser power and microcurrent are reduced proportionally. If the difference is negative and gradually decreases, the laser power and microcurrent are increased proportionally, but neither exceeds the laser power range and microcurrent range corresponding to the target cosmetic area.
[0119] In some embodiments, reducing the laser power to the minimum safe power corresponding to the target cosmetic area and reducing the microcurrent to the minimum safe current corresponding to the target cosmetic area includes: retrieving the minimum safe power value and the minimum safe current value corresponding to the target cosmetic area from the memory; adjusting the drive current of the laser component through a pulse width modulation signal to stabilize the laser power at the minimum safe power value; stabilizing the microcurrent at the minimum safe current value by adjusting the voltage output of the electrode drive circuit; and continuously monitoring the real-time values of the laser power and microcurrent to ensure that they are not lower than the corresponding minimum safe values.
[0120] In some embodiments, if the rotation angle exceeds the rotation angle range of the target cosmetic area, adjusting the laser power to the minimum safe power corresponding to the target cosmetic area and maintaining the microcurrent within the safe current range of the target cosmetic area includes: real-time monitoring of rotation angle data; when the rotation angle is detected to exceed the upper or lower limit of the rotation angle range of the target cosmetic area, immediately sending a minimum safe power control signal to the drive circuit of the laser component to quickly adjust the laser power to the minimum safe power corresponding to the target cosmetic area; and activating a closed-loop control mechanism for the microcurrent to maintain the microcurrent within the safe current range of the target cosmetic area through feedback adjustment until the rotation angle returns to the rotation angle range of the target cosmetic area.
