Description

Technical Field

[0001] The present application relates to the technical field of beauty instruments, and in particular to a beauty instrument control method, a storage medium and an electronic device. Background Art

[0002] With the emergence of home beauty devices, more and more people are starting to use them for skin care. When using them, the contact surface of the electrode head of the beauty device is attached to the skin. The electrode head outputs radio frequency energy to act on the dermis of the skin, promoting collagen growth through cellular thermal effect, thereby achieving the effect of firming and removing wrinkles.

[0003] However, the RF output power of the beauty instrument needs to reach a certain level to achieve a good beauty effect. The RF output power is set when the facial skin and the electrode head are in contact with a large area. If other parts, such as fingers, touch the electrode head when the beauty instrument outputs RF power, the temperature rises too quickly due to the small contact area between the finger and the electrode head. If the contact time is too long, burns may occur, which poses a safety problem. Therefore, it is necessary to provide a beauty instrument control method that can identify the preset risky parts. Summary of the invention

[0004] The purpose of the present application is to overcome the deficiency in the prior art that fingers are prone to burns and to provide a beauty instrument control method, storage medium and electronic device that can identify preset risky areas.

[0005] The technical solution of the present application provides a beauty instrument control method, comprising:

[0006] Get the current skin impedance value;

[0007] If the current skin impedance value is greater than the preset impedance threshold, then

[0008] Controlling the radio frequency power to a first power that is less than a preset power;

[0009] After running for a preset time period, obtaining a first impedance change amount within the preset time period;

[0010] If the first impedance change is greater than or equal to the first change threshold, then

[0011] The contact object is determined to be a preset part, and the RF output is controlled to be turned off.

[0012] Furthermore, the beauty instrument control method also includes

[0013] If the first impedance change is less than the first change threshold, then

[0014] Controlling the radio frequency power to a second power, wherein the second power is less than a preset power and greater than the first power;

[0015] After running for a preset time period, obtaining a second impedance change amount within the preset time period;

[0016] If the second impedance change is greater than or equal to a second change threshold, and the second change threshold is greater than the first change threshold, then

[0017] Determine that the contact object is a preset part and control the RF output to be turned off;

[0018] Otherwise, the RF is controlled to output in normal mode.

[0019] Furthermore, the first power is 5% to 15% of the preset power, and the second power is 25% to 35% of the preset power.

[0020] Furthermore, the first change threshold is 1 to 2 ohms, and the second change threshold is 4 to 5 ohms.

[0021] Furthermore, the preset impedance threshold is 20 to 40 ohms.

[0022] Furthermore, before obtaining the current skin impedance value, the following steps are specifically performed:

[0023] In response to the radio frequency output signal, obtaining the skin impedance value according to a set period;

[0024] If the current skin impedance value meets the sampling condition, the current skin impedance value is output.

[0025] Furthermore, the current skin impedance value satisfies the sampling conditions, specifically including

[0026] Get the set number of skin impedance values ​​collected most recently as the current impedance array;

[0027] Calculate the standard deviation of the current impedance array;

[0028] If the standard deviation of the current impedance array is less than the standard deviation threshold, the current skin impedance value is judged to meet the sampling condition, otherwise all skin impedance values ​​of the current impedance array are cleared.

[0029] The technical solution of the present application also provides a storage medium, which stores computer instructions. When a computer executes the computer instructions, it is used to execute the beauty instrument control method as described above.

[0030] The technical solution of the present application provides an electronic device, comprising at least one processor; and

[0031] a memory communicatively connected to the at least one processor; wherein,

[0032] The memory stores instructions that can be executed by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can execute the beauty instrument control method as described above.

[0033] After adopting the above technical solution, the following beneficial effects are achieved:

[0034] The preset parts with the risk of scalding generally have thicker stratum corneum, which makes the impedance larger, and the contact area between the preset parts and the electrode head is smaller, which makes the temperature rise faster. When the skin impedance value is detected to be too large, and the impedance change within the preset time period is also large, it is judged that the preset parts are in contact, and the RF output is controlled to be turned off to prevent scalding;

[0035] When it is detected that the skin impedance value is too large, the radio frequency power is controlled to be reduced to the second power, which can not only ensure the judgment of the subsequent impedance change amount, but also prevent skin burns during the detection.

[0040] The specific implementation of the present application is further described below with reference to the accompanying drawings.

Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the present application, and should not be regarded as the entirety of the present application or as a limitation or restriction on the technical solution of the application.

[0043] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above-mentioned in this application can be understood according to the specific circumstances.

[0044] A beauty instrument control method in an embodiment of the present application, such as Figure 1 Shown, including

[0045] Step S101: obtaining the current skin impedance value;

[0046] Step S102: If the current skin impedance value is greater than the preset impedance threshold, then

[0047] Controlling the radio frequency power to a first power that is less than a preset power;

[0048] Step S103: After running for a preset time period, obtaining a first impedance change amount within the preset time period;

[0049] Step S104: If the first impedance change is greater than or equal to a first change threshold, it is determined that the contact object is a preset location, and the radio frequency output is controlled to be turned off.

[0050] Specifically, the preset part can be set to a part with a small contact surface with the electrode and a possible risk of burns, such as the elbow, finger tip, finger joint and other parts. Taking the finger as an example, the stratum corneum of the skin of human fingers is thicker, so the skin impedance value is larger. The present application first determines whether the current skin impedance value is greater than the preset impedance threshold to preliminarily determine the finger's mis-touch. And when it is detected that the current skin impedance value is too large, the RF power is controlled to be a first power less than the preset power and then the subsequent finger recognition steps S103-S104 are executed to prevent skin burns.

[0051] The preset power is the normal output power of the beauty instrument in the current working mode, and the specific setting is set according to the working mode of the beauty instrument. The preset impedance threshold can be set to 20 to 40 ohms after comparing a large number of facial skin impedance values ​​and preset skin impedance values. Taking the preset part as an example, the preset impedance threshold is preferably set to 30 ohms.

[0052] Steps S103-S104 perform finger recognition, which identifies whether the contact object is a finger by judging whether the first impedance change within a preset time period is greater than or equal to a first change threshold.

[0053] Specifically, since the contact area between the finger and the electrode head is small, and the RF power of the electrode head is too large relative to the smaller contact area of ​​the finger, the temperature rise rate after the finger contacts the electrode head is higher than the temperature rise rate after the facial skin contacts the electrode head. Therefore, when the impedance change in the preset time period is detected to be greater than the first change threshold, it is determined that the contact object is a finger. In order to prevent the finger from being burned, the RF output is controlled to be turned off. In order to detect obvious impedance changes, the preset time period is set to at least 1 second, and in order to prevent burns, the preset time period cannot be greater than 3 seconds.

[0054] The embodiment of the present application detects the skin impedance value to identify the preset parts, and can accurately identify the preset parts such as fingers, thereby solving the problem that the current beauty instrument cannot identify the parts such as fingers that have the risk of burns and can easily cause burns.

[0055] In one embodiment, the beauty instrument control method further includes

[0056] If the first impedance change is less than the first change threshold, then

[0057] Controlling the radio frequency power to a second power, wherein the second power is less than a preset power and greater than the first power;

[0058] After running for a preset time period, obtaining a second impedance change amount within the preset time period;

[0059] If the second impedance change is greater than or equal to a second change threshold, and the second change threshold is greater than the first change threshold, then

[0060] Determine that the contact object is a preset part and control the RF output to be turned off;

[0061] Otherwise, the RF is controlled to output in normal mode.

[0062] Specifically, the first power is 5% to 15% of the preset power, preferably 10%, and the second power is 25% to 35% of the preset power, preferably 30%. Due to differences in individual skin, in order to prevent misidentification caused by unclear impedance changes at a lower preset power of the radio frequency power, when it is detected that the first impedance change is less than the first change threshold, the radio frequency power is increased and then the second impedance change is judged to ensure that the preset part can be identified.

[0063] The greater the radio frequency power, the greater the change in skin impedance. Therefore, the second change threshold is greater than the first change threshold. Preferably, the first change threshold is 1 to 2 ohms, preferably 2 ohms, and the second change threshold is 4 to 5 ohms, preferably 5 ohms.

[0064] Regarding the determination of the first impedance change and the second impedance change: since the skin impedance of the human body gradually decreases as the temperature rises, the skin impedance value within the preset time period gradually decreases, and the impedance change is obtained by subtracting the ending skin impedance value from the initial skin impedance value of the preset time period.

[0065] In one embodiment, before obtaining the current skin impedance value, the method specifically includes obtaining the skin impedance value according to a set period in response to the radio frequency output signal;

[0066] If the current skin impedance value meets the sampling condition, the current skin impedance value is output.

[0067] In the embodiment of the present application, while receiving the RF output, the skin impedance value is obtained in real time according to the set period, and the set period is set to 0.05 seconds, that is, the skin impedance value is collected 20 times per second. And before outputting the current skin impedance value, it is judged whether the skin impedance meets the sampling conditions, and only the current skin impedance value is valid.

[0068] Furthermore, the current skin impedance value satisfies the sampling conditions, specifically including

[0069] Get the set number of skin impedance values ​​collected most recently as the current impedance array;

[0070] Calculate the standard deviation of the current impedance array;

[0071] If the standard deviation of the current impedance array is less than the standard deviation threshold, the current skin impedance value is judged to meet the sampling condition, otherwise all skin impedance values ​​of the current impedance array are cleared.

[0072] The number of settings is set to at least 10 to ensure the validity of the standard deviation data. When calculating the standard deviation of the current impedance array, the maximum and minimum values ​​are discarded before calculation. The standard deviation threshold is preferably set to 30.

[0073] The embodiment of the present application collects the latest set number of skin impedance values ​​as the current skin impedance array, and determines whether the skin impedance value is valid by calculating its standard deviation. This is because the impedance of human skin changes slowly as the temperature rises. If the skin impedance value fluctuates too much in a short period of time, it can be considered that the factors affecting the skin impedance are not only temperature changes, or the collection of the skin impedance value is incorrect. At this time, it is impossible to accurately identify the preset part through impedance, so the data in the current impedance array is cleared and the impedance value is collected again.

[0077] Step S203: Calculate the standard deviation of the current impedance array;

[0079] Step S205: clearing all skin impedance values ​​in the current impedance array;
