[0018] Please refer to Figure 1 , Figure 1 which is a schematic flowchart of the intelligent control method based on multiple parameters provided by an embodiment of the present invention. The intelligent control method based on multiple parameters in the embodiment of the present invention can be applied to a shaving device, and can adjust the working parameters of the shaving device according to the beard density index, skin pressure index, and skin humidity index to meet the needs of personalized adaptation of users. As Figure 1 shown, the method includes steps S100 to S120.

[0019] S100, controlled by a start instruction for starting the shaving device, respectively obtain the beard density index, skin pressure index, and skin humidity index.

[0020] In the embodiment of the present invention, the shaving device may be an electric shaver, which may include a sensor module, a control module, and an execution module. The sensor module may include an impedance sensor, a pressure sensor array, and a capacitive humidity sensor. The impedance sensor is used to measure the impedance change rate of the skin contact area, which refers to the contact area between the cutter head of the shaving device and the skin. The pressure sensor array is used to detect the force with which the user presses the skin, and the capacitive humidity sensor is used to sense the skin humidity. The control module may include a control chip, which is used to obtain the sensor data detected by the sensor module, calculate a dynamic adjustment coefficient based on a preset formula, and adjust the working parameters of the shaving device according to the dynamic adjustment coefficient to achieve the control of the shaving device. The execution module may include a motor controller and a motor. The motor controller is used to adjust the rotation speed and reciprocating frequency of the blade of the shaving device, and the motor is used to adjust the vibration amplitude of the blade. Both the motor controller and the motor are controlled by the control module.

[0021] When a startup instruction for the shaving device is detected by the user, target parameters can be obtained through the sensor module, and then a beard density index, a skin pressure index, and a skin humidity index can be calculated based on the target parameters. The startup instruction may refer to the user turning on the shaving device. For example, the shaving device may be provided with a switch button, and when the user presses the switch button, it is regarded as receiving the startup instruction. Or for a shaving device with a touch screen, when the user clicks the startup button on the touch screen, it is regarded as receiving the startup instruction.

[0022] After the shaving device is started, the control module controls the sensor module to start and detect the target parameters in real time. It can be understood that the target parameters can be obtained only when the cutter head of the shaving device is in contact with the user's skin. When the shaving device is not in contact with the user's skin, although the sensor module is in a working state, the target parameters obtained can all be 0.

[0023] S110, Calculate a dynamic adjustment coefficient based on the beard density index, the skin pressure index, and the skin humidity index.

[0024] In the embodiments of the present invention, after the beard density index, the skin pressure index, and the skin humidity index are obtained, a dynamic adjustment coefficient can be calculated according to these three indices. The dynamic adjustment coefficient is used to adjust the blade rotation speed, the reciprocating frequency, and the vibration amplitude of the shaving device, so as to realize the adjustment of the working parameters of the shaving device.

[0025] S120, Control the shaving device to perform a shaving action according to the dynamic adjustment coefficient.

[0026] In the embodiments of the present invention, after the dynamic adjustment coefficient is determined, the working parameters of the shaving device can be determined according to the dynamic adjustment coefficient, so as to realize the adjustment of the shaving device. The dynamic adjustment coefficient is related to the beard density index, the skin pressure index, and the skin humidity index, so that the working parameters of the shaving device can be associated with the user's real-time state, meeting the needs of personalized adaptation. It can be understood that the above adjustment process is a real-time adjustment, that is, when any one of the three indices of the beard density index, the skin pressure index, and the skin humidity index changes, the dynamic adjustment coefficient will also change accordingly, and the working parameters of the shaving device will also change.

[0027] See Figure 2 , In some embodiments, such as this embodiment, the intelligent control method based on multiple parameters further includes steps S130 - S131.

[0028] S130, Obtain the impedance change rate and the sampling area of the shaving device;

[0029] S131. Substitute the rate of change in impedance and the sampling area into a first preset formula to calculate the beard density index.

[0030] Among them, the first preset formula is:

[0031] HDI = K 1 ×ΔZ×S(1)

[0032] Among them, HDI is the beard density index, and K 1 is a calibration constant, ΔZ is the rate of change in impedance, and S is the sampling area.

[0033] In an embodiment of the present invention, the rate of change in impedance and the contact area between the cutter net of the cutter head and the skin can be measured by an impedance sensor, where the contact area is the sampling area. After obtaining the rate of change in impedance and the sampling area, substitute the rate of change in impedance and the sampling area into the first preset formula, and calculate the beard density index through the first preset formula.

[0034] For example, if the rate of change in impedance is 50Ω / cm 2 , the sampling area is 2cm 2 , the calibration constant is 0.03, then ΔZ = 50Ω / cm 2 , S = 2cm 2 , K 1 = 0.03. Substituting into the first preset formula, HDI = 3.0 can be obtained. Among them, the calibration constant is related to the cutter net material, and different cutter net materials have different calibration constants.

[0035] See Figure 3 , in some embodiments, such as this embodiment, the intelligent control method based on multiple parameters further includes steps S140 - S141.

[0036] S140. Obtain the average pressure value of the shaving device on the skin;

[0037] S141. Substitute the average pressure value into a second preset formula to calculate the skin pressure index.

[0038] Among them, the second preset formula is:

[0039] SPC = P ÷ P 0 (2)

[0040] Among them, SPC is the skin pressure index, P is the average pressure value, and P 0 is a preset safety threshold.

[0041] In the embodiments of the present invention, the average pressure value can be obtained through a pressure sensor array, and then the average pressure value is substituted into a second preset formula to calculate the skin pressure index through the second preset formula. For example, the average pressure value is 12 kPa, and the preset safety threshold is 15 kPa, that is, P = 12 kPa, P 0 = 15 kPa. Substituting into the second preset formula, SPC = 0.8 can be obtained.

[0042] See Figure 4 , in some embodiments, such as this embodiment, the multi-parameter based intelligent control method further includes steps S150 - S151.

[0043] S150, obtaining the current dielectric constant of the skin;

[0044] S151, substituting the dielectric constant into a third preset formula to calculate the skin humidity index.

[0045] Wherein, the third preset formula is:

[0046] SMF = (ε - ε 0 ) ÷ (ε max - ε 0 )(3)

[0047] Wherein, SMF is the skin humidity index, ε is the dielectric constant, ε 0 is the dielectric constant of dry skin, and ε max is the maximum humidity dielectric constant.

[0048] In the embodiments of the present invention, the current dielectric constant of the skin can be measured through a capacitive humidity sensor, and then the dielectric constant is substituted into the third preset formula to calculate the skin humidity index through the third preset formula. For example, the dielectric constant can be 6.0, the dielectric constant of dry skin is 3.5, and the maximum humidity dielectric constant is 8.0, that is, ε = 6.0, ε 0 = 3.5, ε max = 8.0. Substituting into the third preset formula, SMF = 0.56 can be obtained.

[0049] In some embodiments, such as this embodiment, the multi-parameter based intelligent control method further includes the following steps: substituting the beard density index, the skin pressure index, and the skin humidity index into a fourth preset formula to calculate the dynamic adjustment coefficient, wherein the fourth preset formula is:

[0050] DAC = α × HDI + β × SPC + γ × SMF(4)

[0051] Wherein, HDI is the beard density index, SPC is the skin pressure index, SMF is the skin humidity index, and α, β, and γ are all weight coefficients.

[0052] In the embodiment of the present invention, taking the foregoing example, HDI = 3.0, SPC = 0.8, SMF = 0.56. If α = 0.5, β = 0.3, γ = 0.2, substituting the above parameters into the fourth preset formula, DAC = 0.502 can be obtained.

[0053] In some embodiments, such as this embodiment, the intelligent control method based on multiple parameters further includes the following steps: substituting the dynamic adjustment coefficients into the blade rotation speed adjustment formula, the reciprocating frequency adjustment formula, and the vibration amplitude adjustment formula respectively to adjust the blade rotation speed, the reciprocating frequency, and the vibration amplitude of the shaving device, wherein the blade rotation speed adjustment formula is:

[0054]

[0055] V is the blade rotation speed, V 0 is the reference rotation speed, and DAC is the dynamic adjustment coefficient;

[0056] The reciprocating frequency adjustment formula is:

[0057] F = F 0 ×(1 + (1 - DAC))(6)

[0058] F is the reciprocating frequency, F 0 is the reference frequency;

[0059] The vibration amplitude adjustment formula is:

[0060] A = A 0 ×DAC(7)

[0061] A is the vibration amplitude, A 0 is the reference amplitude.

[0062] In the embodiment of the present invention, if the reference rotation speed is 8000 rpm, the reference frequency is 50 Hz, the reference amplitude is 0.5, and the dynamic adjustment coefficient is 0.5, substituting the dynamic adjustment coefficient into the blade rotation speed adjustment formula, the reciprocating frequency adjustment formula, and the vibration amplitude adjustment formula respectively, the blade rotation speed can be obtained as 16000 rpm, the reciprocating frequency is 75 Hz, and the vibration amplitude is 0.25 mm. That is, the blade rotation speed is increased, the reciprocating frequency is increased, and the vibration amplitude is decreased. If the dynamic adjustment coefficient is changed to 2.27, substituting the dynamic adjustment coefficient into the blade rotation speed adjustment formula, the reciprocating frequency adjustment formula, and the vibration amplitude adjustment formula respectively, the blade rotation speed can be obtained as 3524 rpm, the reciprocating frequency is 13.5 Hz, and the vibration amplitude is 1.14 mm. That is, the blade rotation speed is decreased, the reciprocating frequency is decreased, and the vibration amplitude is increased.

[0063] The present invention also provides a shaving device, which is configured with the multi-parameter based intelligent control method described in any one of the above embodiments. The shaving device includes a sensor module and a control module; the sensor module is used to obtain the rate of change of impedance, the sampling area, the average pressure value, and the dielectric constant respectively; the control module is used to calculate a dynamic adjustment coefficient according to the rate of change of impedance, the sampling area, the average pressure value, and the dielectric constant, and control the shaving device to perform a shaving action according to the dynamic adjustment coefficient.

[0064] Specifically, the shaving device can be an electric shaver, which can include a sensor module, a control module, and an execution module. The sensor module can include an impedance sensor, a pressure sensor array, and a capacitive humidity sensor. The impedance sensor is used to measure the rate of change of impedance of the skin contact area, which refers to the contact area between the cutter head of the shaving device and the skin. The pressure sensor array is used to detect the force with which the user presses the skin, and the capacitive humidity sensor is used to sense the skin humidity. The control module can include a control chip, which is used to obtain the sensor data detected by the sensor module, calculate a dynamic adjustment coefficient based on a preset formula, and adjust the working parameters of the shaving device according to the dynamic adjustment coefficient to achieve the control of the shaving device. The execution module can include a motor controller and a motor. The motor controller is used to adjust the rotation speed and reciprocating frequency of the cutter of the shaving device, and the motor is used to adjust the vibration amplitude of the cutter. Both the motor controller and the motor are controlled by the control module.

[0065] The control module can obtain target parameters through the sensor module. The target parameters include the rate of change of impedance, the sampling area, the average pressure value, and the dielectric constant. Then, based on the target parameters, it calculates a beard density index, a skin pressure index, and a skin humidity index, calculates a dynamic adjustment coefficient, and then determines the working parameters of the shaving device according to the dynamic adjustment coefficient, thereby realizing the adjustment of the shaving device. The dynamic adjustment coefficient is related to the beard density index, the skin pressure index, and the skin humidity index, so that the working parameters of the shaving device can be associated with the user's real-time state, meeting the needs of personalized adaptation. It can be understood that the above adjustment processes are all real-time adjustments, that is, when any one of the three indexes of the beard density index, the skin pressure index, and the skin humidity index changes, the dynamic adjustment coefficient will also change accordingly, and the working parameters of the corresponding shaving device will also change.

[0066] The multi-parameter based intelligent control method and shaving device disclosed in the present invention can calculate a dynamic adjustment coefficient according to the beard density index, the skin pressure index, and the skin humidity index, and then adjust the working parameters of the shaving device according to the dynamic adjustment coefficient, so as to associate the working parameters of the shaving device with the user's state, thereby realizing personalized adaptation.
