Referring to fig. 1, a block diagram of an rf cosmetic apparatus 100 according to an embodiment of the application is shown. As shown in fig. 1, the rf cosmetic instrument 100 includes an electrode 10, a pressure sensor 20, an rf module 30, and a control module 40, wherein the electrode 10 is disposed at an end of the rf cosmetic instrument 100, and is used for contacting skin when the rf cosmetic instrument 100 acts on the skin. The pressure sensor 20 is disposed at an end of the rf cosmetic apparatus 100, and is configured to detect a pressure value when the electrode 10 contacts the skin and is stressed. The rf module 30 is configured to output rf energy to the electrode 10 after activation and to conduct the rf energy to the skin through the electrode 10. The control module 40 is configured to control the rf module 30 to be activated to output rf energy when the electrode 10 is determined to be in contact with the skin according to the pressure value detected by the pressure sensor 20, and to control and adjust the output power of the rf module 30 according to the pressure value detected by the pressure sensor 20 when the rf module 30 outputs rf energy.

According to the radio frequency beauty instrument 100 provided by the embodiment of the application, the pressure sensor 20 is adopted to detect the stress before and after the electrode 10 contacts with the skin so as to determine whether the electrode 10 contacts with the skin, and the radio frequency module 30 is started when the electrode 10 contacts with the skin, and the output power of the radio frequency module 30 is controlled according to the detected pressure value, so that whether the electrode 10 contacts with the skin can be accurately judged under the condition that the current value of the radio frequency beauty instrument 100 is not detected, the opening or closing of the radio frequency module 30 is controlled, and the radio frequency output of the radio frequency module 30 is controlled stably and reliably when the radio frequency module 30 outputs radio frequency energy, thereby bringing better use experience.

The pressure sensor 20 may detect the pressure value of the electrode 10 when the electrode is in contact with the skin and is stressed in real time, or may acquire the pressure value of the electrode 10 when the electrode is in contact with the skin and is stressed at predetermined intervals. The pressure sensor 20 sends the detected pressure value to the control module 40, and the control module 40 compares the pressure value with a preset pressure value when receiving the pressure value, so as to determine whether the electrode 10 is in contact with the skin. Wherein the control module 40 determines that the electrode 10 is in contact with the skin when the pressure value is greater than a preset pressure value, and determines that the electrode 10 is not in contact with the skin when the pressure value is less than or equal to the preset pressure value.

The preset pressure value may be obtained through a test experiment, that is, when the electrode 10 is not in contact with the skin, the pressure value detected by the pressure sensor 20 is taken as the preset pressure value.

When the control module 40 determines that the electrode 10 is in contact with skin, the control module 40 controls the radio frequency module 30 to start to output radio frequency energy, and in the process that the radio frequency module 30 outputs radio frequency energy, the control module 40 also controls and adjusts the output power of the radio frequency module 30 according to the pressure value detected by the pressure sensor 20 so as to adjust the output radio frequency energy.

The pressure sensor 20 may be a strain type pressure sensor, a piezoresistive type pressure sensor, a capacitive type pressure sensor, a piezoelectric type pressure sensor, or the like.

Wherein the radiofrequency cosmetic instrument 100 may comprise at least one electrode 10, the material of the electrode 10 may comprise a conductive material, such as a metal. In some embodiments, the material of the electrode 10 may include copper, titanium, and the like.

The rf module 30 may be a high-frequency ac power module that outputs high-frequency ac power, for example, an inverter that converts dc power of a battery into ac power.

The control module 40 may include a single chip microcomputer, a CPU (central processing unit), a DSP (digital signal processing), and other processing chips.

Wherein controlling the output power of the rf module 30 may adjust the output power by adjusting the output current or the output voltage.

In some embodiments, the rf cosmetic device 100 may act on the skin covered with a cosmetic substance or mask through which the electrode 10 is in indirect contact with the skin, and the rf energy output from the rf module 30 to the electrode 10 may be conducted to the skin through the cosmetic substance or mask. The cosmetic substance may be a substance having a cosmetic skin care effect, such as toner, lotion, essence, white water, emulsion, face cream, eye cream, gel, lipstick, lip cream, skin lotion, moisturizing lotion, etc. In other embodiments, the RF cosmetic device 100 may also act directly on the skin, with the electrode 10 in direct contact with the skin. The skin area on which the rf cosmetic device 100 acts may be facial skin, or any other skin area of the human body.

In some embodiments, the control module 40 controls to increase or decrease the output power of the rf module 30 when the pressure value detected by the pressure sensor 20 increases; the control module 40 controls to decrease or increase the output power of the rf module 30 when the pressure value detected by the pressure sensor 20 decreases.

In some embodiments, when the rf module 30 outputs rf energy, the control module 40 is further configured to determine whether the electrode 10 is in contact with skin according to the pressure value detected by the pressure sensor 20, and control the rf module 30 to stop outputting when it is determined that the electrode 10 is not in contact with skin. Therefore, when the radio frequency cosmetic instrument 100 leaves the skin, the output of the radio frequency energy can be stopped, so that the waste of the energy is avoided, and the power consumption is reduced.

Wherein, the control module 40 determines that the electrode 10 is not in contact with the skin, i.e. the rf cosmetic instrument 100 is away from the skin, when the pressure value detected by the pressure sensor 20 is less than or equal to the preset pressure value.

In some embodiments, the control module 40 determines that the electrode 10 is not in contact with the skin when the pressure value detected by the pressure sensor 20 is less than or equal to the preset pressure value for a period of time. The duration of the period of time can be preset according to actual requirements.

In some embodiments, the foregoing control module 40 controls and adjusts the output power of the rf module 30 according to the pressure value detected by the pressure sensor 20, including: the variation amplitude of the pressure value is determined according to the pressure value detected by the pressure sensor 20 at the current moment and the last moment, when the determined variation amplitude of the pressure value is smaller than a preset variation amplitude, the output power of the radio frequency module 30 is controlled to be unchanged, and when the determined variation amplitude of the pressure value is larger than or equal to the preset variation amplitude, the output power of the radio frequency module 30 is controlled to be regulated.

The pressure sensor 20 may detect a pressure value in real time, and the current time and the previous time may be two adjacent times when detecting in real time. Alternatively, the pressure sensor 20 may detect the pressure value at intervals of the predetermined time, the predetermined time may be set according to actual requirements, and the current time and the previous time are separated by the predetermined time, for example, the predetermined time is 0.8s, the previous time is T1 time, the current time is T2 time, and the time T1 and the time T2 are separated by 0.8s. Obviously, the predetermined time may also be other values.

The preset variation range can be set according to actual requirements. The preset variation amplitude may be stored in the memory of the rf cosmetic apparatus 100 in advance.

By controlling the rf output power to be adjusted when it is determined that the variation amplitude of the pressure value is greater than or equal to the preset variation amplitude, and controlling the rf output power to be unchanged when the variation amplitude is less than the preset variation amplitude, frequent adjustment of the output power of the rf module 30 can be avoided, and the change of the output power of the rf module 30 can be avoided in case that the user carelessly moves the rf cosmetic instrument 100 slightly.

Referring to fig. 2, a block diagram of an rf cosmetic apparatus 100 according to another embodiment of the application is shown. In some embodiments, the rf cosmetic device 100 is configured to act on facial skin, as shown in fig. 2, and the rf cosmetic device 100 further includes a region recognition module 50 configured to recognize a facial region contacted by the electrode 10.

The control module 40 is further configured to set a preset variation amplitude corresponding to the face area identified by the area identifying module 50 as a target preset variation amplitude according to a preset correspondence between the preset face area and the preset variation amplitude, control the output power of the radio frequency module 30 to remain unchanged when the determined variation amplitude of the pressure value is smaller than the target preset variation amplitude, and control to adjust the output power of the radio frequency module 30 when the determined variation amplitude of the pressure value is greater than or equal to the target preset variation amplitude.

By setting the different face areas to respectively correspond to a preset change amplitude, when the detected pressure value changes, the adjustment of the radio frequency output power is more targeted, and whether the radio frequency output power needs to be adjusted or not can be judged according to the change of the pressure value in the different face areas.

The preset correspondence between the face areas and the preset variation ranges defines correspondence between a plurality of face areas and a plurality of preset variation ranges, and each face area corresponds to a preset variation range. The preset variation magnitudes corresponding to the different face regions may be the same or different. The facial region may be one of a periocular region, a cheek region, a forehead region, and a perioral region.

In some embodiments, the preset variation amplitude corresponding to the periocular region is smaller than the preset variation amplitude corresponding to other facial regions, and the preset variation amplitudes corresponding to the forehead region and the perioral region are smaller than the preset variation amplitudes of the cheek region.

The skin in the periocular region is sensitive and fragile compared with the skin in other facial regions, and the preset change amplitude corresponding to the periocular region is smaller than the preset change amplitude corresponding to other facial regions, so that the adjustment of the radio frequency output power in the periocular region according to the change of the pressure value is finer, and better beautifying effect of the periocular region and skin protection of the periocular region can be realized. The forehead area and the lip surrounding area are sensitive and fragile compared with the skin of the cheek area, and the forehead area and the lip surrounding area are set to correspond to the preset change amplitude smaller than the cheek area, so that the adjustment of the radio frequency output power of the forehead area and the lip surrounding area according to the change of the pressure value is finer, and the better beautifying effect of the forehead area and the lip surrounding area and the skin of the forehead area and the lip surrounding area can be achieved.

The preset correspondence between the face area and the preset variation range may be stored in the memory of the rf cosmetic apparatus 100 in advance.

The region recognition module 50 may acquire image information of the face region contacted by the electrode 10, and send the image information to the control module 40, and when the control module 40 receives the image information, the control module performs image processing and analysis on the acquired image information through an algorithm, so as to determine the face region contacted by the electrode 10. Wherein the image information includes skeletal features, facial features such as eyes, nose, lips, eyebrows, skin color, wrinkles, facial contours, facial angles, and the like.

Illustratively, the preset variation amplitude corresponding to the periocular region is 100Pa, and the preset variation amplitude corresponding to the cheek region is 200Pa. Obviously, the preset variation amplitude corresponding to the periocular region and the cheek region can also be other values.

In some embodiments, the control module 40 controls and adjusts the output power of the rf module 30 according to the pressure value detected by the pressure sensor 20, including: and controlling and adjusting the output power of the radio frequency module 30 according to the pressure value detected at the current moment and the pressure value detected in the preset time before the current moment. That is, according to the pressure value detected in a period of time, the output power of the radio frequency module 30 is controlled and adjusted, so that the adjustment of the output power of the radio frequency module 30 can be more accurate, the situation that the adjustment of the output power according to the instantaneous pressure value is too absolute and has a certain contingency is avoided, and the influence on the accuracy of power adjustment is avoided.

Wherein the control module 40 may record the pressure value transmitted by the pressure sensor 20 and store the pressure value in the memory when the pressure value is received. In some embodiments, the control module 40 may control to clear the recorded pressure value when the rf cosmetic apparatus 100 is turned off, so as to reduce the memory space. In other embodiments, the user may select whether to clear the recorded pressure value or not by himself, and the control module 40 may control the clearing of the recorded pressure value in response to a clearing operation by the user.

The preset time length can be set according to actual requirements.

In other embodiments, the control module 40 controls and adjusts the output power of the rf module 30 according to the pressure value detected by the pressure sensor 20, including: and controlling and adjusting the output power of the radio frequency module 30 according to the pressure value detected at the current moment.

In some embodiments, the control module 40 controls and adjusts the output power of the rf module 30 according to the pressure value detected at the current time and the pressure value detected within a preset time period before the current time, including: averaging the pressure value detected at the current moment and the pressure value detected in the preset time before the current moment to obtain an average pressure value; and controlling and adjusting the output power of the radio frequency module 30 according to the average pressure value. By taking an average value of the pressure values over a period of time and controlling the adjustment of the rf output power according to the average value, the accuracy of the adjustment of the output power of the rf module 30 can be improved.

Wherein the average value may be a geometric average value or a weighted average value.

In some embodiments, the average is a weighted average, i.e., the average pressure value obtained is a weighted average pressure value. Wherein the weight of the pressure value detected at the current moment may be greater than the weight of the pressure values detected at other moments. In some embodiments, the weight of the first detected preset number of pressure values is smaller than the weight of the remaining pressure values detected later, and the preset number can be set according to actual requirements. The weights of the pressure values detected in the preset time and the current time may be partially the same or different.

For example, the pressure value detected at the current time is P5, the pressure values detected within a preset period before the current time are P1, P2, P3 and P4, respectively, and the average value of the pressure value detected at the current time and the pressure value detected within the preset period before the current time is obtained, that is, (p1+p2+p3+p4+p5)/5, to obtain the geometric average pressure value p_av.

In some embodiments, the control module 40 controls and adjusts the output power of the rf module 30 according to the pressure value detected by the pressure sensor 20, including: a target output power is determined according to the pressure value detected by the pressure sensor 20, an adjustment mode is determined, and the output power of the radio frequency module 30 is adjusted to the target output power according to the adjustment mode.

The target output power is determined according to the pressure value, so that the target output power can be determined without detecting the current value of the radio frequency cosmetic instrument 100, thereby avoiding the influence of the working temperature of the radio frequency cosmetic instrument 100 and the change of the skin impedance of the human body, and further controlling the radio frequency output of the radio frequency module 30 stably and reliably.

Wherein the determining the target output power according to the pressure value detected by the pressure sensor 20 may include: and determining the output power corresponding to the average pressure value as the target output power according to the preset corresponding relation between the preset pressure value and the output power, or determining the output power corresponding to the pressure value detected at the current moment as the target output power. The preset corresponding relation between the pressure values and the output power defines the corresponding relation between a plurality of pressure values and a plurality of output powers, and each pressure value corresponds to one output power. The preset correspondence between the pressure value and the output power may be stored in the memory of the rf cosmetic apparatus 100 in advance.

In some embodiments, the rf cosmetic apparatus 100 has a plurality of adjustment modes, and when the control module 40 adjusts the output power of the rf module 30 to the target output power according to the adjustment modes, if the pressure value detected by the pressure sensor 20 changes, the control module controls to update the current adjustment mode, and adjusts the output power of the rf module 30 to the target output power according to the updated adjustment modes. When the pressure value detected by the pressure sensor 20 changes, the output power can be adjusted in a timely updated adjustment mode by controlling the updated adjustment mode of the output power, so that the power adjustment mode is adapted to the pressure change received by the electrode 10.

In some embodiments, the control module 40 controlling the update of the current adjustment mode includes: and controlling to switch the current adjusting mode to other adjusting modes or controlling to adjust the adjusting parameters of the current adjusting mode. That is, the current adjustment mode is switched to a new adjustment mode, and the output power of the radio frequency module 30 is adjusted to the target output power in the new adjustment mode, or the adjustment parameter of the current adjustment mode is adjusted, and the output power of the radio frequency module 30 is adjusted to the target output power in the new adjustment parameter. The current adjusting mode is updated by switching a new adjusting mode or adjusting the adjusting parameters of the adjusting mode, so that the adjustment of the radio frequency output power is finer, and the adaptation degree of the adjusting mode of the output power to the change condition of the pressure value can be improved.

In some embodiments, the plurality of adjustment modes includes a linear adjustment mode and a nonlinear adjustment mode, and the adjustment parameter includes a slope of an adjustment curve of the linear adjustment mode and the nonlinear adjustment mode. Wherein the slope of the adjustment curve of the linear adjustment mode is kept unchanged, i.e. the ratio of the output power to the time is unchanged in the adjustment process; the slope of the adjustment curve of the nonlinear adjustment mode changes with time, i.e. the ratio of output power to time changes during adjustment.

The control module 40 controls the current adjustment mode to be switched to other adjustment modes, or controls the adjustment parameters for adjusting the current adjustment mode, including: if the pressure value detected by the pressure sensor 20 increases, increasing the slope of the adjusting curve of the current adjusting mode and/or switching to a linear adjusting mode when the current adjusting mode is a nonlinear adjusting mode; and if the pressure value detected by the pressure sensor 20 decreases, decreasing the slope of the adjustment curve of the current adjustment mode and/or switching to the nonlinear adjustment mode when the current adjustment mode is the linear adjustment mode.

When the pressure value detected by the pressure sensor 20 increases and the current adjustment mode is the linear adjustment mode or the nonlinear adjustment mode, the slope of the adjustment curve of the current adjustment mode is increased, that is, the slope of the adjustment curve of the linear adjustment mode or the slope of the adjustment curve of the nonlinear adjustment mode is increased. When the current adjusting mode is a nonlinear adjusting mode, increasing the slope of the adjusting curve of the current adjusting mode means that the slope of each moment of the adjusting curve after adjustment is larger than the slope of each moment of the adjusting curve before adjustment. Wherein, increasing the slope of the adjustment curve of the current adjustment mode may include: and increasing the slope of the regulating curve of the current regulating mode according to the increasing amount of the pressure value.

When the pressure value detected by the pressure sensor 20 increases and the current adjustment mode is a nonlinear adjustment mode, if the slope of the adjustment curve of the nonlinear adjustment mode gradually decreases, the current adjustment mode may be switched to a linear adjustment mode, and the slope of the adjustment curve of the linear adjustment mode is greater than the slope of the adjustment curve of the nonlinear adjustment mode.

When the pressure value detected by the pressure sensor 20 decreases and the current adjustment mode is the linear adjustment mode or the nonlinear adjustment mode, the slope of the adjustment curve of the current adjustment mode is decreased, that is, the slope of the adjustment curve of the linear adjustment mode is decreased or the slope of the adjustment curve of the nonlinear adjustment mode is decreased. When the current adjusting mode is a nonlinear adjusting mode, reducing the slope of the adjusting curve of the current adjusting mode means that the slope of each moment of the adjusting curve after adjustment is smaller than the slope of each moment of the adjusting curve before adjustment. Wherein, the decreasing the slope of the adjustment curve of the current adjustment mode may include: and reducing the slope of the regulating curve of the current regulating mode according to the reduction of the pressure value.

When the pressure value detected by the pressure sensor 20 decreases and the current adjustment mode is a linear adjustment mode, the current adjustment mode may be switched to a nonlinear adjustment mode, and the slope of the adjustment curve of the nonlinear adjustment mode is smaller than the slope of the adjustment curve of the linear adjustment mode.

In some embodiments, when the control module 40 adjusts the output power of the rf module 30 to the target output power according to the adjustment mode, and the user senses that the skin is not heated sufficiently or senses that the heating effect of the rf cosmetic apparatus 100 is not sufficient, the user slightly moves the rf cosmetic apparatus 100 along the direction close to the skin to make the rf cosmetic apparatus close to the skin, so that the pressure applied to the electrode 10 is increased, and then the pressure value detected by the pressure sensor 20 is increased, at this time, the adjustment mode is updated, specifically, the slope of the adjustment curve of the current adjustment mode is increased or the nonlinear adjustment mode is switched to the linear adjustment mode, so that the rate of adjusting the output power to the target output power can be increased, so that the skin is heated more quickly, and the rf cosmetic effect is improved.

In some embodiments, in the process that the control module 40 adjusts the output power of the rf module 30 to the target output power according to the adjustment mode, when the user feels that the skin is stingy, the user slightly moves the rf cosmetic apparatus 100 along the direction away from the skin, so that the pressure applied to the electrode 10 is reduced, and then the pressure value detected by the pressure sensor 20 is reduced, at this time, the adjustment mode is updated, specifically, the slope of the adjustment curve of the current adjustment mode is reduced or the linear adjustment mode is switched to the nonlinear adjustment mode, so that the process of adjusting the output power to the target output power is relatively gentle, so that the change of the output power is not severe, and the user feel bad.

In some embodiments, the control module 40 is further configured to record the adjustment mode if the pressure value detected by the pressure sensor 20 is unchanged when adjusting the output power of the rf module 30 to the target output power according to the adjustment mode, and record the updated adjustment mode after adjusting the output power of the rf module 30 to the target output power according to the updated adjustment mode.

The foregoing determining adjustment means includes: one adjustment from the recorded adjustment is selected to determine the adjustment. One adjustment from the recorded adjustment modes may be selected by the control module 40 to determine the adjustment mode.

The output power is adjusted by selecting one of the recorded adjusting modes, so that the selected adjusting mode is suitable for users, and the adjusting efficiency of the radio frequency output power can be improved.

The adjustment method can be used for recording the adjustment modes, counting the times at the same time, and selecting the adjustment mode with the largest times as the current adjustment mode for adjusting the output power when the adjustment mode is selected.

In some embodiments, the control module 40 may select an adjustment based on the target output power and the current output power. By determining the adjustment mode according to the target output power and the current output power, when the radio frequency module 30 adjusts the output power according to the determined adjustment mode, the adjustment process of the output power is adapted to the power difference between the target output power and the current output power, so that the adjustment to the target output power can be faster.

In some embodiments, when the power difference between the target output power and the current output power is greater than a preset power difference, determining that the adjustment mode is a linear adjustment mode or a nonlinear adjustment mode, where when the adjustment mode is the nonlinear adjustment mode, the slope of the adjustment curve of the nonlinear adjustment mode is gradually increased. When the power difference is large, the adjustment process of the radio frequency output power can be faster by adopting a linear adjustment mode or a nonlinear adjustment mode with gradually increased slope, the power adjustment efficiency can be improved, and the target output power can be reached at a faster speed.

In some embodiments, when the power difference between the target output power and the current output power is less than or equal to the preset power difference, it is determined that the adjustment mode is a nonlinear adjustment mode, and the slope of the adjustment curve of the nonlinear adjustment mode gradually decreases. When the power difference is smaller, the adjustment process of the radio frequency output power is more gentle by adopting a nonlinear adjustment mode with gradually reduced slope, and a user can feel that the temperature rising process of the skin is more gentle, so that the body feeling of the radio frequency effect is improved.

In some embodiments, the rf cosmetic apparatus 100 is configured to act on facial skin, and the control module 40 controls and adjusts the output power of the rf module 30 according to the pressure value detected by the pressure sensor 20, including: and taking the adjusting mode corresponding to the face area identified by the area identifying module 50 as a target adjusting mode according to the preset corresponding relation between the preset face area and the adjusting mode, and controlling and adjusting the output power of the radio frequency module 30 according to the pressure value detected by the pressure sensor 20 and the target adjusting mode.

Wherein, a target output power can be determined according to the pressure value detected by the pressure sensor 20, and the output power of the radio frequency module 30 is adjusted to the target output power in the target adjustment mode.

The preset correspondence between the facial area and the adjustment mode defines correspondence between the periocular area, the cheek area, the forehead area and the perioral area and the adjustment mode, and the adjustment modes corresponding to different facial areas may be the same or different. The preset correspondence between the facial area and the adjustment mode may be stored in the memory of the rf cosmetic apparatus 100 in advance.

In some embodiments, the slope of the adjustment curve of the adjustment pattern corresponding to the periocular region is less than the slope of the adjustment curve of the adjustment pattern corresponding to the other facial region.

The cosmetic material can be cosmetic liquid directly applied to face, such as toner, essence, gel, etc., or can be nutritional material in facial mask. The detection module can comprise a viscosity sensor, an image sensor, a code reader, an electronic tag reader-writer and the like.

The viscosity sensor is used for detecting the viscosity value of the cosmetic substance covered on the skin when the electrode 10 is in contact with the skin to output a detection signal including the viscosity value, and the control module 40 determines the type of the cosmetic substance according to the viscosity value included in the detection signal when receiving the detection signal. The cosmetic substance used with the rf cosmetic instrument 100 includes a plurality of types, the viscosity values of the plurality of types of cosmetic substances may be obtained through a viscosity test in advance, and then a corresponding relationship between the viscosity values and the types of the cosmetic substances may be obtained, and the control module 40 may determine the type of the cosmetic substance currently covered on the skin according to the corresponding relationship between the viscosity values and the types of the cosmetic substances and the viscosity values included in the received detection signal. The viscosity sensor can detect the viscosity value of the beautifying liquid directly smeared on the face and also can detect the viscosity value of nutrient substances in the mask.

The image sensor, the code reader and the electronic tag reader are used for detecting the tag of the facial mask when the radio frequency beauty instrument 100 is in contact with the skin on which the facial mask is laid, so as to output a detection signal comprising the tag, and the control module 40 determines the type of the beauty substance according to the tag comprising the detection signal when receiving the detection signal.

The control module 40 controls and adjusts the output power of the rf module 30 according to the pressure value detected by the pressure sensor 20, including: according to the preset correspondence between the preset type of the cosmetic substance and the adjustment mode, the adjustment mode corresponding to the type of the cosmetic substance detected by the detection module is used as a target adjustment mode, and the output power of the radio frequency module 30 is controlled and adjusted according to the pressure value detected by the pressure sensor 20 and the target adjustment mode.

In some embodiments, the different types of cosmetic substances differ in at least one of molecular weight, viscosity, and skin permeation rate.

In some embodiments, the preset correspondence between the types of the cosmetic substances and the adjustment modes defines that the molecular weight and/or the viscosity are positively correlated with the slope of the adjustment curve of the adjustment modes, that is, the slope of the adjustment curve of the adjustment mode corresponding to the cosmetic substance with higher molecular weight and/or viscosity is larger than the slope of the adjustment curve of the adjustment mode corresponding to the cosmetic substance with lower molecular weight and/or viscosity, or the adjustment mode corresponding to the cosmetic substance with higher molecular weight and/or viscosity may be a linear adjustment mode and the slope of the adjustment curve of the linear adjustment mode gradually increases, the adjustment mode corresponding to the cosmetic substance with lower molecular weight and/or viscosity may be a nonlinear adjustment mode and the slope of the adjustment curve of the nonlinear adjustment mode gradually decreases. Wherein the cosmetic material with the molecular weight larger than the preset molecular weight is a high molecular weight cosmetic material, the cosmetic material with the molecular weight smaller than or equal to the preset molecular weight is a low molecular weight cosmetic material, the cosmetic material with the viscosity larger than the preset viscosity is a high viscosity cosmetic material, and the cosmetic material with the viscosity smaller than or equal to the preset viscosity is a low viscosity cosmetic material. Compared with the cosmetic material with lower molecular weight and/or viscosity, the cosmetic material with higher molecular weight and/or viscosity is difficult to absorb, and radio frequency energy is difficult to penetrate, and the higher the molecular weight and/or viscosity is, the larger the slope of the regulating curve of the regulating mode is, so that the regulating process of the radio frequency output power is faster when the molecular weight and/or viscosity is higher, and the regulating efficiency of the radio frequency output power is improved, and the absorption of the cosmetic material is accelerated. By setting the high molecular weight and/or high viscosity cosmetic substances to correspond to the linear regulation mode, and gradually increasing the slope of the regulation curve of the linear regulation mode, the regulation process of the radio frequency output power can be faster, and the regulation efficiency of the radio frequency output power can be improved and the absorption of the cosmetic substances can be accelerated.

In some embodiments, the preset correspondence between the type of the cosmetic substance and the adjustment mode defines that the skin permeation rate is inversely related to the slope of the adjustment curve of the adjustment mode, that is, the slope of the adjustment curve of the adjustment mode corresponding to the cosmetic substance with a faster skin permeation rate is smaller than the slope of the adjustment curve of the adjustment mode corresponding to the cosmetic substance with a slower skin permeation rate, or the adjustment mode corresponding to the cosmetic substance with a high skin permeation rate may be a nonlinear adjustment mode and the slope of the adjustment curve of the nonlinear adjustment mode gradually decreases, the adjustment mode corresponding to the cosmetic substance with a low skin permeation rate may be a linear adjustment mode and the slope of the adjustment curve of the linear adjustment mode gradually increases. By setting the higher the skin permeation rate, the smaller the slope of the regulating curve of the regulating mode, the regulating process of the radio frequency output power is more gentle when the skin permeation rate of the cosmetic substance is higher, and the regulating process is matched with the skin permeation rate of the cosmetic substance. By setting the cosmetic substance with high skin permeation rate to correspond to the nonlinear regulation mode, and gradually reducing the slope of the regulation curve of the nonlinear regulation mode, the regulation process of the radio frequency output power is more gentle when the skin permeation rate of the cosmetic substance is higher, and the radio frequency output power is matched with the skin permeation rate of the cosmetic substance.
