Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
According to an embodiment of the present invention, there is provided a cosmetic instrument, as shown in fig. 1, an internal structure of which includes: the facial mask comprises a general control processor 101, an auxiliary clamping device 102, a temperature control device 103, a frequency modulation device 104, a whitening device 105, a plurality of hot compress devices 106 and a plurality of cold compress devices 107, wherein the whitening device 105 is positioned in the central area of the beauty instrument, and the hot compress devices 106 and the cold compress devices 107 are distributed in a staggered manner to cover different skin areas in the face. It should be noted that the number of hot compress devices 106 and cold compress devices 107 may be designed according to specific product requirements, and the illustration of fig. 1 is only an example.
Specifically, the general control processor 101 may control the temperature control device 103 according to the temperature collected by the temperature sensor and the temperature required for beauty treatment, and adjust the radio frequency and/or the radio frequency amplitude of the beauty treatment instrument in real time through the frequency modulation device 104 according to the collected human face echo signal. Furthermore, the overall control processor 101 is also capable of processing complex operations in time to generate an optimal personalized cosmetic regimen for selection by a user. The auxiliary gripping means 102 is responsible for gripping some auxiliary appliances, such as sponge, gauze, etc., when beautifying.
Illustratively, the cosmetic instrument may be a radio frequency cosmetic instrument. The working principle of the radio frequency beauty equipment is mainly to realize the expected treatment purpose by utilizing the heat effect of current or electric field energy on human tissues. It should be noted that, for the device for treating by adopting the current mode, the depth of the tissue penetrated by the current and the corresponding tissue level should be described, so as to determine the theoretical current densities of different levels with different depths; for the equipment adopting the electric field mode treatment, an electric field distribution model and the covered tissue depth are constructed, and the energy absorption degree of different tissues is clear. The skin is directly penetrated by Radio Frequency (RF) waves, and the impedance formed by the skin enables cell molecules to generate strong resonance rotation (in the order of millions of times per second) so as to generate heat energy, so that the temperature of the dermis of the skin is instantaneously increased, and immediate collagen tightening and collagen regeneration are generated by the stimulation of the dermis.
It should be noted that the current mode of action can be divided into monopolar and bipolar (including multipolar), wherein monopolar radio frequency is used in combination with neutral electrode. The electric field action is typically applied with a higher operating frequency, either in a monopolar fashion, which may not use a neutral electrode, or in a bipolar fashion.
The specific working principle of the general control processor 101 can be referred to in the following detailed description of the method embodiments, and will not be described herein.
According to an embodiment of the present invention, there is provided a cosmetic instrument control method embodiment, it being noted that the steps shown in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases the steps shown or described may be performed in an order other than that shown or described herein.
In this embodiment, a control method of a beauty treatment apparatus is provided, which can be used for a general control processor 101 shown in fig. 1, such as a microcontroller (Microcontroller Unit, MCU), a single chip microcomputer, etc., fig. 2 is a flowchart of a control method of a beauty treatment apparatus according to an embodiment of the present invention, and as shown in fig. 2, the flowchart includes the following steps:
step S201, transmitting an electrical signal to the face, and collecting a first echo signal reflected by the face based on the electrical signal.
Specifically, a radio frequency handheld cosmetic instrument is adopted to provide personalized treatment for a user, and the electric signal emitted to the face of the user is a composite electric signal, wherein the low-frequency part of the composite electric signal is used for heating the epidermis layer of the face, and the high-frequency part is used for heating the dermis layer.
In step S202, when the first echo signal is detected as a combined signal reflected by different skin areas in the face, the first echo signal is decomposed to obtain second echo signals corresponding to the skin areas.
Specifically, the face information carried by the echo signals reflected by different skin areas is different, so that different control actions can be formulated according to different skin areas by judging whether the acquired first echo signals are combined signals containing multiple frequencies, and if so, performing frequency synthesis and decomposition on the first echo signals to obtain second echo signals corresponding to the skin areas. Illustratively, the skin area may include, but is not limited to, cheek, forehead, eyes, neck, and the like.
Step S203, according to the second echo signals, impedance values corresponding to the skin areas are obtained.
Specifically, the echo current of each skin area may be calculated according to the second echo signal, and the impedance value corresponding to each skin area may be calculated based on the echo current and the emission voltage of the beauty instrument, and detailed implementation steps may refer to description of related technologies, which will not be repeated herein.
Step S204, according to the impedance value, the working parameters of the beauty instrument aiming at different skin areas are adjusted.
Specifically, the current impedance value of the skin is used as the adjustment basis of the working parameters of the beauty instrument, the skin impedance value is different from the skin temperature, the skin temperature can only detect the temperature of the epidermis layer and can not reflect the state in the dermis layer, the change of parameters such as the water content of skin tissue, the electrolyte content, the tissue temperature and the like can influence the skin impedance value, and the skin impedance value can reflect the comprehensive state of the dermis layer and the epidermis layer of the skin in real time. Therefore, the working parameters of the beauty instrument aiming at different skin areas are timely adjusted based on the skin impedance value, so that the skin reaches the optimal state.
According to the beauty instrument control method, the electric signals are transmitted to the face, the first echo signals reflected by the face based on the electric signals are collected, then when the first echo signals are detected to be combined signals reflected by different skin areas in the face, the first echo signals are decomposed to obtain the second echo signals corresponding to the skin areas, so that the impedance values corresponding to the skin areas are obtained, the working parameters of the different skin areas are adjusted in a targeted mode according to the impedance values, and personalized treatment requirements of users are met.
In this embodiment, a control method of a beauty treatment apparatus is provided, which can be used for a general control processor 101 shown in fig. 1, such as a microcontroller (Microcontroller Unit, MCU), a single chip microcomputer, etc., fig. 3 is a flowchart of a control method of a beauty treatment apparatus according to an embodiment of the present invention, and as shown in fig. 3, the flowchart includes the following steps:
step S301, transmitting an electrical signal to the face, and collecting a first echo signal reflected by the face based on the electrical signal. Please refer to step S201 in the embodiment shown in fig. 2 in detail, which is not described herein.
In step S302, when the first echo signal is detected as a combined signal reflected by different skin areas in the face, the first echo signal is decomposed to obtain second echo signals corresponding to the skin areas. Please refer to step S202 in the embodiment shown in fig. 2, which is not described herein.
Step S303, according to the second echo signals, impedance values corresponding to the skin areas are obtained.
In some alternative embodiments, the step S303 includes:
and a step a1, decomposing the second echo signal to obtain a low-frequency echo signal and a high-frequency echo signal.
And a2, obtaining the impedance value of the epidermis layer of each skin area according to the low-frequency echo signal corresponding to the skin area.
And a step a3 of obtaining the dermis layer impedance value of each skin region according to the high-frequency echo signal corresponding to the skin region.
Specifically, by transmitting a composite electrical signal to the face, a low frequency portion of the composite electrical signal heats the epidermis layer, a high frequency portion heats the dermis layer, and a dermis layer impedance value and an epidermis layer impedance value are calculated from the reflected echo signals, so that the current temperatures of the dermis layer and the epidermis layer are determined from the impedance values. According to the low-frequency echo signal and the high-frequency echo signal obtained after the second echo signal is decomposed, the impedance values of the dermis layer and the epidermis layer of each skin area are obtained, the comprehensive states of the dermis layer and the epidermis layer of the skin are reflected in real time, and the control accuracy of the beauty instrument is improved.
Step S304, according to the impedance value, the working parameters of the beauty instrument aiming at different skin areas are adjusted.
Specifically, the step S304 includes:
step S3041, determining skin temperatures corresponding to different skin areas according to the impedance values.
Specifically, the current dermis layer temperature and epidermis layer temperature can be calculated according to the dermis layer impedance value, the epidermis layer impedance value and a pre-obtained impedance-temperature curve, so that the working parameters of the beauty instrument can be conveniently adjusted, and the control accuracy of the beauty instrument is improved.
Step S3042, for each skin area, adjusting the radio frequency and/or the radio frequency amplitude of the hot compress device and/or the cold compress device corresponding to the skin area according to the skin temperature of the skin area.
Specifically, for each skin region, the radio frequency and/or the radio frequency amplitude of the hot compress device and/or the cold compress device corresponding to the skin region is adaptively adjusted according to the epidermis layer temperature and the dermis layer temperature of the skin region. For example, when the skin temperature is greater than the temperature threshold corresponding to the skin region, the radio frequency and/or the radio frequency amplitude of the heat application device corresponding to the skin region may be appropriately reduced, or the radio frequency and/or the radio frequency amplitude of the cold application device corresponding to the skin region may be appropriately increased. Therefore, based on the skin temperatures corresponding to different skin areas, the radio frequency and/or the radio frequency amplitude of the hot compress device and/or the cold compress device corresponding to each skin area are adjusted, and the control accuracy of the beauty instrument is improved.
In addition, as the temperature change of the skin can cause the change of the skin impedance value, the radio frequency and/or the radio frequency amplitude can be adjusted through the impedance change quantity of the current period compared with the previous period, and as the impedance change quantity can reflect the change rate of the skin temperature, scalding caused by too fast temperature rise can be avoided, hysteresis does not exist in the detection of the skin impedance value, the radio frequency can be adjusted in time, and the safety is improved.
In some alternative embodiments, as shown in fig. 4, the radio frequency of the cosmetic device may be adaptively adjusted by an adaptive controller (adaptive adjuster), and specific calculation steps may be described with reference to the related art, which is not described herein.

As shown in fig. 6, in the adjustment process of the adaptive controller, the range of the deviation value e (k) and the deviation change rate ec (k) obtained each time is larger, and the target rf frequency value required by each skin area needs a more specific and accurate interval, so that the fuzzy inference is modified according to the change of the rf frequency of the skin area acquired each time, thereby achieving the purpose of adjusting the target rf frequency value required by each skin area in real time.
The preset calibration mechanism is designed based on the radio frequency values output at different skin areas, referring to fig. 6 again, relevant parameters are required to be changed continuously according to the output radio frequency values, parameter conversion and frequency modulation control are performed through fuzzy reasoning and fuzzy de-fuzzy to output target frequency values to a controlled target (i.e. a beauty instrument), and meanwhile, the target frequency values are fed back to a control center to be compared with performance evaluation indexes (i.e. satisfaction degree scores or calibration grades of users). And the output frequency is adjusted in real time by applying a self-adaptive fuzzy control algorithm according to the output frequency value of the target skin area obtained through real-time feedback. It should be noted that, the fuzzy inference rule is a core of the fuzzy control algorithm, and specific reference may be made to the description of the related art, which is not repeated here.
According to the beauty instrument control method, the electric signals are transmitted to the face, the first echo signals reflected by the face based on the electric signals are collected, then when the first echo signals are detected to be combined signals reflected by different skin areas in the face, the first echo signals are decomposed to obtain the second echo signals corresponding to the skin areas, so that the impedance values corresponding to the skin areas are obtained, the working parameters of the different skin areas are adjusted in a targeted mode according to the impedance values, and personalized treatment requirements of users are met. In addition, according to the working parameters of the beauty instrument adjusted for different skin areas, a beauty scheme is generated, and based on the satisfaction degree score of the user and a preset verification mechanism, the beauty scheme is adjusted and stored, so that the secondary use of the user is facilitated, and the user experience is improved.
The control method of the beauty treatment instrument of the present invention will be described in detail with reference to a specific application example, as shown in fig. 7A, which mainly includes the following steps:
step one, transmitting an electric signal to the face, collecting a first echo signal reflected by the face based on the electric signal, collecting face information of a working area of the beauty instrument, and analyzing radio frequency and impedance values of the collected dermis and epidermis to pre-execute related beauty actions next.
And step two, comparing the data acquired in real time with prestored parameters, and determining the skin cortex of the target skin area, and combining external environment parameters to determine the treatment parameter range of each working mode of the beauty instrument, so that the parameter differences in different treatment modes and different purposes can be distinguished conveniently, and a personalized pre-execution scheme is generated for the matching of a general control processor.

As shown in fig. 7B, an electrical signal is transmitted to the target skin area through the measuring electrode, the radio frequency and the radio frequency amplitude are determined according to the measured impedance value of the target skin area, a control signal is generated, the parameters of the target skin area are adjusted according to the radio frequency and the radio frequency amplitude, different impedances represent different thicknesses of the skin, and then the adaptive adjustment of different skin thicknesses is realized. The acquired first echo signals are decomposed through the composite electric signals emitted to the face, wherein the low-frequency part heats the epidermis layer, the high-frequency part heats the dermis layer, the impedance of the dermis layer and the epidermis layer is calculated according to the echo signals, and then the current temperatures of the dermis layer and the epidermis layer are determined according to the impedance, so that the working parameters of the beauty instrument are adjusted in a self-adaptive mode. When the frequency of the beauty instrument to the target skin is judged to be in the high-frequency range, the medium-frequency range and the low-frequency range by the self-adaptive frequency modulation algorithm, the instruction of the general control processor is executed by the frequency modulation (temperature control) device, and the mode (ice compress, hot compress and whitening DWHP ultra-penetration technology) is reasonably configured, so that the self-adaptive personalized treatment effect is achieved.
For example, when the frequency of the target skin is in the high-frequency range (2 MHz-3 MHz), the medium-frequency range (1 MHz-2 MHz) and the low-frequency range (less than 1 MHz), the instruction of the general control processor is executed through the frequency modulation (temperature control) device, and the mode (ice compress, hot compress and whitening DWHP ultra-penetration technology) is reasonably configured, so that the self-adaptive personalized treatment effect is achieved. As shown in fig. 7C, in 10 rf frequency adjustments, the handover fluctuation rate of 3 frequency bins is decreasing, and is approaching the set target value, which indicates that the control method can better and quickly realize the user demand.
According to the invention, the change of the skin impedance value can be caused by the acquired skin temperature change, the radio frequency output is adjusted through the impedance change quantity of the current period compared with the previous period, the scald caused by the too fast temperature rise can be avoided as the change rate of the skin temperature can be reflected by the impedance change quantity, and the hysteresis does not exist in the detection of the skin impedance, so that the radio frequency output can be adjusted in time, the safety is improved, and a feasible technical service is provided for solving the personalized treatment problem for users. The skin temperature of each skin area is reflected in time and the radio frequency output is adjusted in a self-adaptive mode according to the treatment effect of each cosmetology, so that the combination of different parameter performances is realized, and the treatment of a single skin area and a plurality of skin areas is realized. In addition, the user can customize a mode suitable for the skin state of the user, provide a guide head covering different working areas, generate a summary of the beauty effect in the use period, provide the user with the technical effect of personalized treatment, and if the deviation between the treatment effect and the treatment estimated scheme is larger, need to revise the treatment scheme in time; if the treatment effect is better, the treatment effect is stored in the control center to form a memory file, so that a user can review the treatment file at any time.
