[0002] The flexible beauty instrument uses the principle of microcurrent to accelerate the movement of active ions under the action of electrodes, helping skin cells absorb the nutrients in skin care products, and delivering the ingredients needed by the skin to the dermis, giving the skin healthy vitality, strengthening the skin barrier, and fundamentally solving skin problems.

[0003] Most beauty devices use the method of adjusting the voltage directly through the gear setting and adjusting the degree of body sensation through the set fixed frequency, which has been used for muscle movement and improving relaxation. However, due to the deviation of the electronic circuit and the interference of external factors such as the difference in skin impedance, the current output stability is insufficient, resulting in poor effects such as lifting, soothing, detumescence and rejuvenation, making it difficult to meet users' needs for a variety of beauty effects.

DETAILED DESCRIPTION

[0014] 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.

[0015] like Figure 1 As shown, the present invention provides a method for controlling multiple composite currents of a flexible beauty instrument, and the specific steps include: Obtain the real-time current and frequency of the electrode head, and use the PID algorithm to modulate the pulse width and voltage; PID modulation uses proportional, integral and differential modulation to output the modulation signal to the controlled object; Based on the received signal, the controlled object feeds back the adjustment result. If the modulation result does not match the set result, the input current and frequency are adjusted. If the modulation result matches the set result, an accurate control signal is output to act on the skin.

[0016] Specifically, the modulation of the invention includes two modes: current regulation and frequency regulation.

[0017] like Figure 2 As shown. For current regulation, the steps include: The current detection module detects the output current of the electrode head in real time, uses the PID algorithm to control the pulse width and voltage, and calculates the current current deviation to obtain the proportional value by comparing the current current with the preset current. 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.

[0018] The control value can be obtained by combining the three regulation rules of proportion, integration and differentiation. Among them, the proportional regulation is used to calculate the current error to prevent the instantaneous deviation from being too large, and the integral regulation keeps accumulating the deviation; when the voltage is in a steady state, the error is zero, which can reduce the total current error. The differential regulation is used to predict future errors and play a role in rapid regulation. Through precise current control, different effects can be achieved. By testing the optimal current values ​​corresponding to the lifting, soothing, detumescence and rejuvenation effects, the currents for different beauty effects can be set.

[0019] like Figure 3 As shown, for frequency regulation, the steps are: identify the real-time output frequency through the frequency detection device, and fine-tune the frequency output by PID calculation, so that the frequency can act on the human skin more accurately, thereby achieving a more accurate skin care effect.

[0020] In this embodiment, for different frequencies, the present invention provides a group of frequencies that can present different effects on the skin, as follows: Lifting: 50-100 Hz; Soothing: 1-10 Hz; De-swelling: 10-50 Hz; Revitalization: 50-120 Hz. Initially, according to different skin care effects, a fixed frequency output current is set. The frequency detection device and the current detection device detect the current frequency as PID input through feedback, and control the current output through the PID output value, thereby correcting the current output and making the frequency and current more accurate.

[0021] The experimental results show that, using the beauty instrument of the present invention, users can feel obvious lifting and soothing effects in a short time. User feedback shows that the application of multiple composite currents significantly improves the beauty effect, the device is easy to operate, and the user satisfaction is high.

[0022] The system used in the present invention includes: a power control module, a current detection output module, a controller and a plurality of electrode heads. The controller controls the power control module to generate a stable current output through a PID algorithm. The current detection output module is configured with a variety of current generation modules, including low-frequency current, high-frequency current and pulse current modules. The current detection module detects the current acting on the face in real time, and controls the current frequency output and intensity output in real time. By adjusting the output of each module, the compounding and switching of the current are realized.

[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.
