Description

Technical Field

[0001] This invention relates to the field of beauty technology, and in particular to a beauty instrument control method, storage medium, and electronic device. Background Technology

[0002] The working principle of radiofrequency (RF) beauty devices is mainly to utilize the thermal effect generated by electric current or electric field energy on human tissue to achieve the desired treatment purpose. In the treatment of skin and scars, RF beauty devices primarily use the thermal effect generated by electrical energy to act on the dermis or subcutaneous tissue, causing collagen cells to shrink due to heat, resulting in reversible thermal damage. This induces the skin to activate its own repair mechanism, thereby causing the synthesis of new collagen fibers and collagen remodeling. RF beauty devices all have temperature control algorithms used to adjust the RF output power in real time when acting on the human skin.

[0003] Radio frequency (RF) beauty devices often have temperature sensors with large time constants and slow thermal response, meaning the detected temperature is not real-time. Furthermore, heating the skin via RF electrodes results in a very rapid temperature rise, potentially far exceeding the thermal response speed of the temperature sensor. This makes it difficult for RF beauty devices to effectively maintain stable temperature control.

[0004] Existing temperature control methods for radio frequency (RF) beauty devices primarily rely on accelerometers to determine device movement. When the device is moving, it outputs at a set level; when it's stationary, the output stops. However, during the development of this invention, the inventors discovered the following drawbacks in existing RF beauty device temperature control methods:

[0005] 1) If the beauty device is fixed in a certain position on the skin and the user is moving it, there is a risk of burns;

[0006] 2) There is a risk of burns when the beauty device has a small range of motion and the output is at a high level. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of existing beauty device control methods, such as the risk of burns and inaccurate temperature control, and to provide a beauty device control method, storage medium, and electronic device.

[0008] The technical solution of the present invention provides a method for controlling a beauty device, comprising:

[0009] The current temperature of the skin in contact with the electrode head of the beauty device and the acceleration of the moving beauty device are obtained;

[0010] The PID coefficients are obtained based on the acceleration and the preset acceleration-coefficient relationship table.

[0011] The PWM control value of the beauty device is calculated based on the PID coefficient and the current temperature.

[0012] The output power of the beauty device is controlled according to the PWM control value.

[0013] Furthermore, calculating the PWM control value of the beauty device based on the PID coefficients and the current temperature includes:

[0014] Calculate the current temperature difference between the current temperature and the preset target temperature;

[0015] Calculate the average temperature difference of the current temperature difference within a preset time period;

[0016] Calculate the deviation between the current temperature difference and the historical temperature difference at the previous moment;

[0017] The PWM control value is calculated based on the current temperature difference, the average temperature difference, the deviation temperature difference, and the PID coefficient.

[0018] Furthermore, the PID coefficients include a first weighting coefficient, a second weighting coefficient, and a third weighting coefficient. The step of calculating the PWM control value based on the current temperature difference, the average temperature difference, the deviation temperature difference, and the PID coefficients includes:

[0019] The PWM control value is obtained by summing the product of the current temperature difference and the first weighting coefficient, the product of the average temperature difference and the second weighting coefficient, and the product of the deviation temperature difference and the third weighting coefficient.

[0020] Further, the first weighting coefficient includes sequentially increasing first sub-weighting coefficients, second sub-weighting coefficients, third sub-weighting coefficients, and fourth sub-weighting coefficients; the second weighting coefficient includes sequentially increasing fifth sub-weighting coefficients, sixth sub-weighting coefficients, seventh sub-weighting coefficients, and eighth sub-weighting coefficients; and the step of summing the product of the current temperature difference and the first weighting coefficient, the product of the average temperature difference and the second weighting coefficient, and the product of the deviation temperature difference and the third weighting coefficient to obtain the PWM control value includes:

[0021] If the acceleration meets the preset first speed threshold, the product of the current temperature difference and the first sub-weighting coefficient, the product of the average temperature difference and the fifth sub-weighting coefficient, and the product of the deviation temperature difference and the third weighting coefficient are summed to obtain the PWM control value;

[0022] If the acceleration meets the preset second speed threshold, the product of the current temperature difference and the second sub-weighting coefficient, the product of the average temperature difference and the sixth sub-weighting coefficient, and the product of the deviation temperature difference and the third weighting coefficient are summed to obtain the PWM control value, wherein the preset second speed threshold is greater than the preset first speed threshold.

[0023] If the acceleration meets the preset third speed threshold, the product of the current temperature difference and the third sub-weighting coefficient, the product of the average temperature difference and the seventh sub-weighting coefficient, and the product of the deviation temperature difference and the third weighting coefficient are summed to obtain the PWM control value, and the preset third speed threshold is greater than the preset second speed threshold.

[0024] If the acceleration meets the preset fourth speed threshold, the product of the current temperature difference and the fourth sub-weighting coefficient, the product of the average temperature difference and the eighth sub-weighting coefficient, and the product of the deviation temperature difference and the third weighting coefficient are summed to obtain the PWM control value, wherein the preset fourth speed threshold is greater than the preset third speed threshold.

[0025] Furthermore, the step of controlling the output power of the beauty device according to the PWM control value further includes:

[0026] If the PWM control value is greater than the preset control threshold, and the deviation between the current temperature difference and the historical temperature difference at the previous moment is greater than the preset temperature difference threshold, the PWM control value is adjusted according to the deviation temperature difference.

[0027] Furthermore, adjusting the PWM control value based on the temperature deviation includes:

[0028] The PWM compensation value is calculated using the following formula:

[0029] y = a * log 10 xb

[0030] Where y is the PWM compensation value; x is the temperature deviation; a is a constant; b is a constant;

[0031] The PWM control value is adjusted according to the PWM compensation value.

[0032] The present invention also provides a storage medium that stores computer instructions, which, when executed by a computer, are used to perform all steps of the beauty device control method described above.

[0033] The present invention also provides an electronic device, comprising:

[0034] At least one processor; and,

[0035] A memory communicatively connected to the at least one processor; wherein,

[0036] The memory stores instructions that can be executed by the at least one processor to enable the at least one processor to perform the beauty device control method as described above.

[0037] The above technical solution has the following beneficial effects: By acquiring the current temperature of the skin in contact with the electrode head of the beauty device and the acceleration of the beauty device in real time, the PID coefficient is obtained according to the acceleration and the preset acceleration-coefficient relationship table. The PWM control value of the beauty device is calculated according to the PID coefficient and the current temperature. The output power of the beauty device is controlled according to the PWM control value, thereby controlling the temperature of the beauty device. This achieves more accurate and safer temperature control of the beauty device, avoiding burns when the beauty device is fixed in a certain position on the skin or when the beauty device is used for small-area treatment and the output is at a high level.

[0045] Example 1

[0046] like Figure 1 As shown, Figure 1A flowchart of a beauty device control method provided in Embodiment 1 of the present invention includes:

[0047] Step S101: Obtain the current temperature of the skin in contact with the electrode head of the beauty device and the acceleration of the movement of the beauty device;

[0049] Step S103: Calculate the PWM control value of the beauty device based on the PID coefficients and the current temperature;

[0050] Step S104: Control the output power of the beauty device according to the PWM control value.

[0051] Specifically, when the beauty device starts working, the controller executes step S101 to obtain the current temperature of the skin in contact with the electrode head of the beauty device and the acceleration of the beauty device's movement; then, the controller executes step S102 to obtain the PID coefficient corresponding to the acceleration from a preset acceleration-coefficient relationship table; then, the controller executes step S103 to calculate the PWM control value of the beauty device using a PID algorithm based on the PID coefficient and the current temperature; finally, the controller executes step S104 to control the output power of the beauty device based on the PWM control value, thereby controlling the temperature of the beauty device, achieving more accurate and safer temperature control of the beauty device, and avoiding burns.

[0052] In this embodiment of the invention, the current temperature of the skin in contact with the electrode head of the beauty device and the acceleration of the beauty device's movement are acquired in real time. PID coefficients are obtained based on the acceleration and a preset acceleration-coefficient relationship table. The pulse width modulation (PWM) control value of the beauty device is calculated based on the PID coefficients and the current temperature. The on / off ratio of the PWM is adjusted according to the PWM control value to control the output power of the beauty device, thereby controlling the temperature of the beauty device. This achieves more accurate and safer temperature control of the beauty device, avoiding burns when the beauty device is fixed to a certain position on the skin or when the beauty device is used for small-area treatment and the output is at a high level.

[0053] In one embodiment, step S103 includes:

[0054] Calculate the current temperature difference between the current temperature and the preset target temperature;

[0055] Calculate the average temperature difference of the current temperature difference within the preset time period;

[0056] Calculate the temperature difference between the current temperature difference and the historical temperature difference at the previous moment;

[0057] The PWM control value of the beauty device is calculated based on the current temperature difference, average temperature difference, deviation temperature difference, and PID coefficient.

[0058] Specifically, when the current temperature T is obtained C After adjusting for the PID coefficients, the controller calculates the current temperature and the preset target temperature T. D Current temperature difference T X That is, T X =T D -T C Secondly, the controller calculates the average temperature difference ΔT within a preset time period, i.e., ΔT = (T X1 +T X2 +T X3 +…T Xn The value is calculated as ) / n, where n is the number of current temperatures acquired within a preset time period; then, the controller calculates the current temperature difference T. X The historical temperature difference T from the previous moment X ' temperature difference D' X D X =T X -T X Finally, the controller calculates the PWM control value using the PID algorithm based on the current temperature difference, average temperature difference, deviation temperature difference, and PID coefficient. It then adjusts the PWM on / off ratio according to the PWM control value to control the output power of the beauty device, thereby controlling the temperature of the beauty device. This achieves more accurate and safer temperature control of the beauty device and avoids burns.

The calculation of the PWM control value based on the current temperature difference, the average temperature difference, the deviation temperature difference, and the PID coefficients includes:

[0061] The PWM control value is obtained by summing the product of the current temperature difference and the first weighting coefficient, the product of the average temperature difference and the second weighting coefficient, and the product of the deviation temperature difference and the third weighting coefficient.

[0062] In one embodiment, to further and more accurately and safely control the temperature of the beauty device, the step of controlling the output power of the beauty device according to the PWM control value further includes:

[0063] If the PWM control value is greater than the preset control threshold, and the deviation between the current temperature difference and the historical temperature difference at the previous moment is greater than the preset temperature difference threshold, the PWM control value is adjusted according to the deviation temperature difference.

[0064] Specifically, if the PWM control value is greater than the preset control threshold, a large temperature difference will cause the temperature to rise too quickly, which can quickly reduce the output power of the beauty device to ensure safety during use; a small temperature difference will cause the temperature to rise more slowly, which can gradually reduce the output power of the beauty device to improve comfort.

[0065] In one embodiment, to further and more accurately and safely control the temperature of the beauty device, the step of adjusting the PWM control value based on the temperature deviation includes:

[0066] The PWM compensation value is calculated using the following formula:

[0067] y = a * log 10 xb

[0068] Where y is the PWM compensation value; x is the temperature deviation; a is a constant; b is a constant;

[0069] Adjust the PWM control value based on the PWM compensation value.

[0081] Step S210: Sum the product of the current temperature difference and the first weighting coefficient, the product of the average temperature difference and the second weighting coefficient, and the product of the deviation temperature difference and the third weighting coefficient to obtain the PWM control value;

[0082] Step S211: Control the output power of the beauty device according to the PWM control value.

[0083] Specifically, when the beauty device starts working, the controller executes step S201 to obtain the acceleration of the beauty device's movement in real time through an accelerometer or similar means; then, the controller executes step S202 to determine whether the acceleration meets a preset first speed threshold. If it does, step S206 is executed; otherwise, step S203 is executed. In step S203, it is determined whether the acceleration meets a preset second speed threshold. If it does, step S207 is executed; otherwise, step S204 is executed. In step S204, it is determined whether the acceleration meets a preset third speed threshold. If it does, step S208 is executed; otherwise, step S209 is executed. 05; In step S205, it is determined whether the acceleration meets the preset fourth speed threshold. If yes, step S209 is executed; otherwise, step S201 is executed. Then, the controller executes step S210 to sum the product of the current temperature difference and the first weighting coefficient, the product of the average temperature difference and the second weighting coefficient, and the product of the deviation temperature difference and the third weighting coefficient to obtain the PWM control value. Finally, the controller executes step S211 to control the output power of the beauty device according to the PWM control value, thereby controlling the output power of the beauty device according to the different moving speeds of the beauty device and the corresponding weighting coefficients, further improving the accuracy.

[0084] The preset first speed threshold, preset second speed threshold, preset third speed threshold, and preset fourth speed threshold can be set according to user needs. The preset second speed threshold is greater than the preset first speed threshold, the preset third speed threshold is greater than the preset second speed threshold, and the preset fourth speed threshold is greater than the preset third speed threshold.

[0085] The first, second, third, fourth, fifth, sixth, seventh, and eighth sub-weighting coefficients can be set according to user needs.

[0086] In this embodiment, the order of steps S202-S209 is only for ease of explanation and does not constitute a limitation on the claims. Those skilled in the art should understand that as long as the controller determines that the acceleration meets the corresponding speed threshold (preset first speed threshold, preset second speed threshold, preset third speed threshold, or preset fourth speed threshold), the corresponding steps can be performed.
