DETAILED DESCRIPTION

[0011] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0012] The present invention provides a control method for instant lifting, and the specific steps thereof include: Set the current and frequency of different facial areas and detect the output voltage, current and frequency signals; Based on the detected current and frequency signals, they are compared with the set input current and frequency to obtain an error value; based on the error value, a PID algorithm is used to perform signal modulation to adjust the EMS electrical signal of the control output.

[0013] Based on the detected voltage and current, the skin impedance is calculated, and the input current and frequency are adjusted according to the calculated impedance value.

[0014] like Figure 1 As shown, the beauty instrument system used in the present invention includes: a PID control module, an EMS output module, a signal detection feedback module, an impedance identification module and a plurality of electrodes.

[0015] PID Control Module uses advanced control algorithms (such as PID control) to ensure the stability and accuracy of current intensity and frequency output.

[0016] The signal detection feedback module includes voltage detection, current detection, and frequency detection. The signal detection feedback module is equipped with high-precision sensors to monitor the EMS voltage, current, and frequency output in real time, and dynamically adjust according to changes in skin impedance. The signal detection feedback module detects the current current, voltage, and frequency of the skin through resistance.

[0017] The impedance recognition module calculates skin impedance by real-time voltage and current recognition and by calculating the average value of the voltage and current ratio. Through the designed intelligent algorithm, the frequency and intensity of the current are automatically adjusted according to the user's skin impedance and facial area to achieve the best lifting effect.

[0018] During the detection process, the current detection module sets the current sampling resistor at a location with low power supply interference, such as between two voltage-stabilizing capacitors of the power supply. The current collected by the current sampling resistor is converted through filtering to eliminate clutter interference, making the detection more accurate. During the detection process, the frequency detection module captures the actual frequency acting on the skin through a timer. A voltage detection device is set on the electrode, and the controller detects the effect on the skin in real time.

[0019] In this embodiment, the PID algorithm module: after collecting the current, the current current and frequency are used as PID inputs, compared with the set current and frequency, and the current current and frequency deviations are calculated to obtain the proportional value. The integral value is calculated by calculating the sum of the deviations over a period of time, and the differential value is obtained by calculating the difference between the deviations. The control value is obtained by combining the three adjustment rules of proportion, integration, and differentiation. The current error is calculated by proportion to prevent the instantaneous deviation from being too large. The integral accumulates the deviation continuously. The error must be zero in the steady state, reducing the total current error. Differentiation can predict future errors and play a role in rapid adjustment.

[0020] The current size is set according to the different human body impedances, and the corresponding current size is the best value for the instant lifting effect on the facial muscles, and the set frequency size is the best value for the instant effect on the face. Through precise current frequency control, a better lifting effect can be achieved.

[0021] Impedance identification module: Different human body impedances are calculated based on the relationship between real-time output voltage and output current, and the average value of the voltage and current ratio is calculated to obtain skin impedance. During the implementation process, different facial partitions and different skin impedances determine the settings of current and frequency. The current detection and frequency detection module feedback is compared with the set value, and the control value is obtained through PID calculation to control the output of EMS.

[0022] The experimental results show that, using the control method of the present invention, users can feel an obvious face lifting effect in a short time. According to user feedback, the control method significantly improves the beauty effect, the device is easy to operate, and the user satisfaction is high.

[0023] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
