[0059] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] Example 1

[0061] Currently, most beauty devices on the market typically consist of a treatment head and a body structure for easy and secure grip. During use, the user holds the device to guide the treatment head into close contact with the facial skin, thereby applying heat to the skin. This process, utilizing heat conduction, effectively activates skin cell vitality, accelerates metabolism, and enhances the skin's absorption of various skincare products, thus achieving the beauty effects of improving skin texture and beautifying the complexion.

[0062] However, when a user repeatedly heats a specific area of ​​the face multiple times in a short period of time, the heat absorbed by the skin in that area will accumulate excessively, causing the skin temperature to rise sharply beyond the normal tolerance range, which may lead to burns and pose a direct threat to the user's skin health.

[0063] Therefore, embodiments of the present invention provide a method for temperature control and protection of a beauty device to ensure the safety and comfort of the user during use.

[0064] Please refer to Figure 1 This is a flowchart illustrating a temperature control and protection method for a beauty device according to Embodiment 1 of the present invention. This method is applicable to scenarios where a user uses a beauty device to heat the skin, such as the face. The method can be implemented by software and / or hardware. Specifically, the method includes the following steps:

[0065] S102. Activate the beauty head to heat the skin, and time the duration of the beauty head's contact with the skin, or the interval between two consecutive contacts of the beauty head with the skin, to obtain a third timing duration.

[0066] It should be noted that beauty devices include various instruments that care for the skin, such as hair removal devices, radio frequency beauty devices, light therapy beauty devices, and moisturizing devices.

[0067] The beauty head of a beauty device is the component that directly applies heat to the skin for beauty treatments. Once activated, the beauty head heats the skin in a specific way. The purpose of this heating is diverse. On one hand, simply raising the skin temperature can achieve specific beauty effects, such as promoting blood circulation and enhancing the absorption of skincare products. On the other hand, during normal operation of the beauty device, when various beauty technologies such as phototherapy, microcurrent, radio frequency, electroporation, and ultrasound are applied to the skin, these technologies inevitably generate heat during operation, leading to a warming sensation on the skin.

[0068] Detecting the contact between the beauty head and the skin is usually achieved using sensors, such as pressure sensors or capacitive sensors.

[0069] The pressure sensor detects the pressure applied to the beauty head. When the beauty head comes into contact with the skin, the skin exerts pressure on the beauty head, and this pressure change is detected by the pressure sensor. The pressure sensor transmits the detected pressure signal to the control device, which determines whether the beauty head is in contact with the skin based on the received signal.

[0070] Because a certain capacitance is formed between the skin and the beauty head, a capacitive sensor determines whether the beauty head is in contact with the skin by detecting changes in capacitance. When the beauty head approaches or touches the skin, the capacitance value changes accordingly, and the sensor converts this change into an electrical signal and transmits it to the control device for judgment.

[0071] In this step, the beauty head of the device is first activated to begin heating the skin. Simultaneously, the system times the duration of contact between the beauty head and the skin; alternatively, it can time the interval between two consecutive contacts. The final timing result is recorded as the third timing duration.

[0072] By monitoring the duration of skin contact with the beauty head in real time, information on the contact time between the beauty head and the skin can be obtained, providing basic data support for subsequent judgment on whether there are any abnormal operations.

[0073] S103. Detect whether the third timing duration is less than the preset third duration threshold; if yes, then execute S104; if no, then execute S105, or if no, then continue executing S103.

[0074] It should be noted that the third timing duration obtained above is compared with the preset third timing threshold to check whether the third timing duration is less than the preset third timing threshold.

[0075] If the detection result is "yes", that is, the third timing duration is less than the preset third duration threshold, then step S104 is executed.

[0076] If the detection result is "no", that is, the third timing duration is greater than or equal to the preset third duration threshold, there are two processing methods to choose from: one is to execute step S105; the other is to continue to execute step S103 and continue to perform duration detection and judgment. Figure 1 This illustrates step S105.

[0077] The third duration threshold is an important criterion for determining whether the contact between the beauty head and the skin may cause abnormalities. Through this detection and judgment step, potentially risky contact situations can be preliminarily screened, providing a basis for further detection of whether abnormal contact events have been triggered.

[0078] S104. Determine whether to trigger the detection of abnormal contact events and start timing to obtain the first timing duration.

[0079] It should be noted that when the third timing duration is determined to be less than the preset third timing threshold, the system determines that the abnormal contact event detection mechanism needs to be triggered. Simultaneously, timing begins immediately after the abnormal contact event detection is triggered, and the resulting timing is recorded as the first timing duration; the first timing duration and the third timing duration are independent of each other.

[0080] It is understandable that the first timing duration and the third timing duration are independent of each other, meaning that the first timing duration and the third timing duration are two different timing processes, which record different duration information respectively, and do not interfere with each other or include each other.

[0081] Triggering abnormal contact event detection means the system begins to focus on potentially dangerous operations. By recording the initial timing duration, a duration benchmark can be provided for subsequent assessments of whether abnormal contact events occur frequently within a short period.

[0082] S105. Determine that the detection of abnormal contact events is not triggered.

[0083] It should be noted that when the third timing duration is greater than or equal to the preset third timing threshold, the system determines that the current contact between the beauty head and the skin is within the normal range, and there is no need to trigger the detection mechanism for abnormal contact events.

[0084] This step avoids unnecessary anomaly detection under normal operating conditions, thereby improving system efficiency and reducing unnecessary consumption of computing resources.

[0085] S106. Detect whether the first timing duration is less than a preset first duration threshold, and whether the beauty head has an abnormal contact event within the first timing duration, and the number of occurrences reaches a preset number threshold; if yes, then execute S107; if no, then continue to execute S106.

[0086] It should be noted that during the first timing period, the system simultaneously checks whether the following three conditions are met:

[0087] Whether the first timing duration is less than the preset first duration threshold.

[0088] Did an abnormal contact event occur with the beauty head within the first timing period?

[0089] Has the number of abnormal contact events reached a preset threshold, such as two? Figure 9 As shown.

[0090] If all three conditions above are met, i.e. the detection result is "yes", then proceed to step S107.

[0091] If any of the above three conditions is not met, i.e. the detection result is "no", then continue to execute step S106 and continue to perform condition detection.

[0092] By comprehensively testing these three conditions, it is possible to more accurately determine whether there are frequent abnormal contact events occurring in a short period of time, thereby promptly identifying dangerous operations that may cause burns.

[0093] S107. Turn off the beauty head or reduce the power of the beauty head.

[0094] It should be noted that when an abnormal contact event is detected in the beauty head within the first timing period and the number of occurrences reaches the preset threshold, the system will immediately take protective measures, including shutting down the beauty head to stop it from working; or reducing the power of the beauty head to reduce its heating intensity.

[0095] Understandably, taking immediate measures to shut off the beauty head or reduce the power can effectively prevent excessive accumulation of skin temperature due to abnormal contact, thereby providing comprehensive safety protection for users when using handheld beauty devices, improving the user experience, significantly reducing the probability of burns, and making the use of beauty devices safer and more reliable.

[0096] This invention incorporates timing and detection technology to monitor the duration of contact between the beauty head and the skin, as well as the interval between two consecutive skin contacts, thereby establishing a highly efficient safety protection mechanism. This mechanism can detect abnormal user behavior during the use of the handheld beauty device, such as excessively short single skin contact durations or excessively short intervals between two consecutive skin contacts. Such actions are abnormal. Once the monitoring system detects such abnormal behavior, it immediately triggers the detection of abnormal contact events.

[0097] When the detection results of abnormal contact events show that the number of abnormal contact events has reached a preset safety threshold within a preset duration threshold, this embodiment of the invention will quickly take effective intervention measures. Specifically, the system will automatically shut down the beauty head, or significantly reduce the power output of the beauty head without affecting the basic functions of the beauty device. This measure can effectively prevent further rapid increases in skin temperature, avoid skin damage due to excessive heat, and thus provide users with comprehensive and thorough safety protection.

[0098] From the user's perspective, this innovative solution in this invention greatly enhances the user experience of handheld beauty devices. Users can enjoy the convenience and efficient beauty effects of the device without worrying about the risk of burns due to improper operation. This undoubtedly increases user trust and satisfaction with the product, and helps drive the entire industry towards greater safety and reliability, making handheld beauty devices more aligned with modern consumers' dual pursuit of safety and quality.

[0099] Please refer to Figure 2 In one embodiment of this example, in Figure 1 Based on this, prior to S102, the method further includes:

[0100] S101. Detect whether the beauty head of the beauty device is in contact with the skin; if not, continue to execute S101; if yes, execute S102.

[0101] It should be noted that this embodiment saves power by designing the beauty head to start heating only after it is turned on and in contact with the skin.

[0102] Specifically, the beauty head offers two activation options. One is that the beauty head immediately activates the heating function upon power-on. This method is simple and direct, but may lead to unnecessary power consumption because the heating function operates even when not in contact with the skin. The other option is that the beauty head does not immediately activate the heating function upon power-on, but only after detecting contact with the skin. This design effectively saves power because the heating function only activates when actually needed, avoiding energy waste caused by prolonged idling after power-on. This design not only improves the energy efficiency of the beauty device but also extends its lifespan and is more environmentally friendly.

[0103] In summary, by adding step S101 before S102—which detects whether the beauty head is in contact with the skin—the heating function is ensured to be activated only after the beauty head comes into contact with the skin. This design not only improves the energy efficiency of the beauty device and saves power consumption but also extends the device's lifespan and is more environmentally friendly. In this way, the beauty device is more energy-efficient during use, while also providing users with a safer and more comfortable experience.

[0104] For example, consider the following usage scenario: A user is using a beauty device for skin care. Normally, the device needs to be slid across the skin or stamped on one area for a period of time before moving to another to achieve skin care. However, if the user receives a phone call or needs to attend to other matters, but the beauty device remains on while the user is on their face, they may not be slid or stamped on one area at a time, but instead, they may be rapidly touching the skin multiple times in a short period, like a chicken pecking at rice. This rapid, repeated contact can easily cause burns. This invention detects such scenarios and shuts down the beauty head or reduces its power, thereby reducing the risk of burns.

[0105] In one embodiment of this example, in Figure 1 Based on the above, after S107, subsequent steps with different directions are added. The core purpose is still to reduce the risk of burns caused by abnormally high skin temperature due to excessive heat accumulation during the process of the beauty device heating the skin, through a series of detection and control operations, so as to ensure safety and improve user experience.

[0106] Please refer to Figure 3 On the one hand, after S107, the method may further include:

[0107] S108. The duration of turning off the beauty head or reducing the power of the beauty head is timed to obtain a second time duration, and the second time duration is detected to be less than a preset second time duration threshold; if yes, then S109 is executed; if no, then S110 is executed, or if no, then S108 is continued.

[0108] It should be noted that, Figure 3 This indicates the case where S110 is executed if not.

[0109] When the beauty head is turned off or the power is reduced, the internal timing device begins to time the duration of this state, thus obtaining the second timing duration.

[0110] The preset second duration threshold is a pre-defined time limit. By determining whether the second timing duration is less than this threshold, it is determined whether the beauty head has been in the off or low-power state for a sufficient period of time. If it is less than the threshold, it means that the duration is still short and there may still be a certain risk of burns upon re-contact, so the current state needs to be maintained, and S109 is executed; if it is greater than or equal to the threshold, it means that sufficient time has elapsed, the risk of burns has decreased, and S110 is executed.

[0111] S109. Continue to turn off the beauty head, or continue to reduce the power of the beauty head.

[0112] It should be noted that when the second timing duration is less than the preset second duration threshold, the beauty head will remain off or in a low-power state. This is to ensure that excessive heat accumulation is continuously avoided during a potentially risky short period, further protecting skin safety.

[0113] S110, End.

[0114] It should be noted that when the second timing duration is greater than or equal to the preset second duration threshold, it indicates that sufficient time has elapsed to reduce the risk of burns, and the entire control process can end at this point. Users can then restart the beauty device as needed.

[0115] In summary, the newly added steps S108-S110 form a relatively simple subsequent control process. After the beauty head is turned off or the power is reduced, a timer and comparison with a preset threshold determine whether to maintain the current state or end the process. This method ensures continuous safety during potentially risky short periods, and promptly terminates control once the risk is reduced, avoiding unnecessary operational restrictions and improving both flexibility and safety.

[0116] Please refer to Figure 4 On the other hand, after S107, the method may also further include:

[0117] S108. The duration of turning off the beauty head or reducing the power of the beauty head is timed to obtain a second time duration, and the second time duration is detected to be less than a preset second time duration threshold; if yes, then S109 is executed; if no, then S110 is executed, or if no, then S108 is continued.

[0118] It should be noted that, Figure 4 This indicates the case where S110 is executed if not.

[0119] and Figure 3 The process is the same as S108 in the illustration. When the beauty head is turned off or the power is reduced, a second timing period is started to obtain the second timing duration, and its relationship with the preset second duration threshold is detected. If it is less than the threshold, S109 is executed; if it is greater than or equal to the threshold, S110 is executed.

[0120] S109. Continue to turn off the beauty head, or continue to reduce the power of the beauty head.

[0121] It should be noted that, similarly, when the second timing duration is less than the preset second duration threshold, the beauty head will remain off or in a low-power state to reduce the risk of excessive heat accumulation again.

[0122] S110. Detect whether the beauty head comes into contact with the skin again; if yes, proceed to S111; if no, continue to proceed to S110.

[0123] It should be noted that when the second timing duration is greater than or equal to the preset second duration threshold, the system begins detecting whether the beauty head is in contact with the skin again. This detection is performed using a pressure sensor or capacitive sensor, based on the same principle as step S100. If no contact is made, the detection continues to ensure that the beauty head is indeed in contact with the skin before restarting or increasing the power.

[0124] S111. Activate the beauty head or increase the power of the beauty head.

[0125] Furthermore, within a preset second duration threshold, actions such as the user placing the beauty device on their skin or increasing the power level of the beauty device can be ignored, and only actions such as turning off the beauty head or setting it to low power can be performed to reduce the risk of burns.

[0126] It should be noted that when the beauty head is detected to be in contact with the skin again, it indicates that the normal beauty procedure can proceed. At this point, the beauty head should be activated or its power increased to restore it to normal working condition and continue providing beauty services to the user.

[0127] In summary, the newly added steps S108-S111 constitute a more complete subsequent control process. After the beauty head is turned off or the power is reduced, a timer and threshold comparison are used to determine whether to continue maintaining the state. Once sufficient time has elapsed, the system checks whether the beauty head is in contact with the skin again. Only if contact is detected is the device restarted or the power increased. This method is more rigorous, ensuring that the skin is in an acceptable heating state when the beauty device is restarted, further improving the safety of using the device and allowing users to use it for daily skincare with greater peace of mind.

[0128] In one embodiment of this example, the specific definition of an "abnormal contact event" is determined by setting different duration-related conditions to define what kind of skin contact situations are considered abnormal.

[0129] That is, in S106, the abnormal contact event is:

[0130] The duration of skin contact is less than the preset fourth duration threshold, or the interval between two adjacent skin contacts is less than the preset fifth duration threshold, or the duration between the previous skin contact and the next skin contact is less than the preset sixth duration threshold.

[0131] It's important to note that for skin contact durations shorter than a preset fourth duration threshold: a specific duration standard, known as the "fourth duration threshold," is defined. When the duration of a skin contact is less than this preset threshold, the skin contact event is considered an abnormal contact event. For example, if the fourth duration threshold is set to 200 milliseconds, then a skin contact lasting only 100 milliseconds meets this condition and is considered an abnormal contact.

[0132] For instances where the interval between two consecutive skin contacts is less than a preset fifth time threshold: This condition focuses on the duration between two consecutive skin contacts. A "fifth time threshold" is pre-set; when the interval between two consecutive skin contacts is less than this threshold, it is considered an abnormal contact event. For example, if the fifth time threshold is set to 50 milliseconds, and a second skin contact occurs only 50 milliseconds after the first skin contact, then these two contacts meet the condition and are considered abnormal. This situation suggests that the contact behavior is too frequent.

[0133] For cases where the time between the last skin contact and the next skin contact is less than a preset sixth time threshold: This condition is similar to the previous one, but the wording is slightly different. It also sets a "sixth time threshold," but here it emphasizes the time span between the end of one skin contact and the beginning of the next. If this time span is less than the preset sixth time threshold, it is considered an abnormal contact event. For example, if the sixth time threshold is set to 80 milliseconds, if the next skin contact begins only milliseconds after the previous one ended, then this condition is met, and it is considered abnormal. This also helps identify cases with abnormally high contact frequency, reflecting unreasonable user operations.

[0134] In summary, by using these three different but related duration conditions, abnormal skin contact events are comprehensively and meticulously defined from multiple dimensions such as contact duration, adjacent contact interval, and previous and subsequent contact interval, so as to more accurately identify and handle possible abnormal situations.

[0135] In one embodiment of this invention, when the system determines that the power of the beauty head needs to be reduced to implement protective measures, it provides a variety of flexible and scientific power reduction methods, including three modes: linear reduction, step reduction, and reduction according to a preset curve.

[0136] One method is the linear reduction mode, which follows a uniform and continuous pattern of change. In this mode, the power of the beauty head gradually decreases at a constant rate over time. Mathematically, the relationship between power and time exhibits a linear characteristic, meaning the change in power is directly proportional to the change in time. For example, setting the initial power as P0, after time t, the power decreases to P... t Furthermore, within any time interval Δt, the change in power ΔP remains constant, which can be expressed as ΔP=kΔt (where k is a constant representing the rate of power reduction).

[0137] The linear power reduction method is simple, intuitive, and easy to control. It allows the power of the beauty head to smoothly transition to a lower level, avoiding the excessive impact of sudden power changes on the performance of the beauty device and the user experience. At the same time, this uniform reduction method helps to precisely control the heat received by the skin, allowing the skin temperature to drop more gently and reducing discomfort caused by sudden temperature changes.

[0138] Stepped power reduction: This method divides the power reduction process into multiple discrete stages. Each stage corresponds to a specific power value, and the power remains constant within that stage. When a preset time condition is reached or other triggering conditions are met, the power suddenly decreases to the next lower stage, forming a step-like downward trend. For example, the initial power is set to P1. After a period of time t1, the power decreases to P2 and remains at that level for t2, then decreases to P3, and so on.

[0139] The advantage of a stepped power reduction method lies in its better controllability and predictability. By appropriately setting the power value and duration of each step, it can be flexibly adjusted according to different usage scenarios and skin conditions. For example, for users with sensitive skin, more and smaller steps can be set to make the power reduction process smoother; while for situations requiring rapid reduction of heat input, the number of steps can be reduced, and the power reduction magnitude of each step can be increased. In addition, the stepped power reduction method can be easily integrated with other control functions of the system to achieve more complex control strategies.

[0140] The preset curve reduction method adjusts the power of the beauty head according to a pre-defined mathematical curve. These curves can be various functional forms, such as exponential curves, logarithmic curves, sine curves, etc., and the specific choice depends on the optimization requirements of the power reduction process. For example, when using the exponential curve reduction method, the power change over time follows an exponential decay law, i.e., P(t) = P0e^(-t / t). −kt (Where P0 is the initial power, k is the attenuation coefficient, and t is time). By adjusting the parameters of the curve, the rate and trend of power reduction can be precisely controlled.

[0141] Preset curve reduction modes offer more precise and personalized power control. Different curve types can simulate different heat release patterns to meet the needs of different users and different beauty care treatments. For example, an exponential curve reduction mode allows the power to decrease rapidly in the initial stage, quickly reducing heat input, and then gradually flattening out in the later stage to prevent the skin temperature from dropping too quickly; while a logarithmic curve reduction mode allows the power reduction process to be slower and more uniform, suitable for care scenarios with lower requirements for skin irritation. In addition, preset curve reduction modes can also be combined with the skin's thermal response characteristics to achieve more intelligent and efficient protection.

[0142] In summary, these three methods of reducing the power of the beauty head each have their own characteristics. The system can flexibly select or combine these methods according to the actual usage, skin characteristics, and protection needs to ensure that while effectively reducing the risk of burns, it provides users with a safer, more comfortable, and personalized beauty care experience.

[0143] Please refer to Figure 5 In one embodiment of this example, in Figure 1 Based on this, new steps S201 and S202 are introduced to add a judgment mechanism during the detection of abnormal contact events, so as to handle the detection process more reasonably, avoid unnecessary continuous detection, and ensure that the beauty head can continue the subsequent normal operation process when it is in normal contact with the skin.

[0144] S201. During the detection of abnormal contact events, it is detected whether the first timing duration is less than a preset first duration threshold, and whether a normal contact event occurs on the beauty head within the first timing duration; if yes, then S202 is executed; if no, then S201 is continued.

[0145] It should be noted that during the detection of abnormal contact events, two conditions are checked simultaneously. The first condition is whether the "first timing duration is less than a preset first timing threshold". The second condition is whether a normal contact event occurs on the beauty head within the first timing duration.

[0146] If both of the above conditions are "yes"—that is, the first timing duration is less than the preset first timing threshold, and a normal contact event occurs on the beauty head within the first timing duration—then step S202 is executed. If one or both of these conditions are "no," then step S201 is executed, meaning the detection of these two conditions continues. This design is intended to observe whether normal contact occurs on the beauty head within a certain time range (defined by the first timing threshold) to determine the subsequent processing method.

[0147] S202, End the detection of abnormal contact events and return to execute S101.

[0148] It should be noted that this step is executed when the judgment result in S201 is "yes". Specifically, this operation ends the detection of abnormal contact events, which means that monitoring for abnormal skin contact of the beauty head is no longer continued. Then, the process returns to execute step S102. S102 is the initial step of the entire protection method. Returning to execute it is to restart a complete control flow and ensure that the beauty head operates according to the established normal process after normal skin contact.

[0149] Specifically, the normal contact event is:

[0150] The duration of skin contact exceeds the preset fourth duration threshold, or the interval between two adjacent skin contacts exceeds the preset fifth duration threshold, or the duration between the previous skin contact and the next skin contact exceeds the preset sixth duration threshold.

[0151] It should be noted that, for example, if the fourth duration threshold is set to 200 milliseconds, then the condition is met if the beauty head is in contact with the skin for 200 milliseconds. This indicates that the contact duration is long enough and likely meets the requirements for normal operation.

[0152] For example, if the fifth duration threshold is set to 50 milliseconds, and a second skin contact occurs 50 milliseconds after the first skin contact, then the interval between these two contacts meets the condition and is considered normal. This helps to avoid excessively frequent contact and ensures the reasonableness of the contact behavior.

[0153] For example, the sixth duration threshold is set at 80 milliseconds. If the next skin contact begins 80 milliseconds after the previous skin contact ends, this condition is met and considered normal. This is also to regulate the frequency of contact and ensure that contact behavior conforms to normal operating procedures.

[0154] In summary, by adding steps S201 and S202 and defining normal contact events, the process for detecting abnormal contact events in the protection method has been improved, making it more scientific and reasonable. It can effectively detect abnormal situations and adjust the process in a timely manner when normal contact is restored, thus ensuring the safety and normal use of beauty equipment.

[0155] Please refer to Figure 6 In one embodiment of this example, in Figure 1 Building upon step S107, the method further includes steps S112 and S113 to enhance the user experience and the level of intelligent device management:

[0156] S112. Indicates the reason why the beauty head is turned off or the power is reduced, and suggests the following operation.

[0157] It's important to note that after the system shuts down or reduces the power of the beauty head, it will communicate the reason for this to the user through the beauty device's display screen, indicator lights, voice prompts, or a connected mobile device (such as a mobile app). Reasons may include detecting abnormal contact events that have reached a preset threshold, the beauty head being in contact with the skin for too long, or an abnormal interval between two consecutive skin contacts. The system will also provide corresponding suggestions, such as checking the contact between the beauty head and the skin, waiting a while before restarting the beauty head, or checking for any malfunctions in the beauty device.

[0158] This step is crucial for users. It allows them to understand the specific reasons why the beauty device is taking protective measures, preventing confusion or anxiety due to a lack of awareness. By providing suggested operations and guiding users to handle the current situation correctly, it helps them use the beauty device better and reduces the possibility of safety issues arising again due to misoperation. From a product user experience perspective, clear prompts enhance user trust and satisfaction with the product, improving its overall quality image.

[0159] S113. If no operation is detected within the preset waiting time, the device will automatically enter standby mode or shut down.

[0160] It's important to note that after informing the user that the beauty head is off or its power has been reduced, and providing suggested actions, the system will start a preset waiting timer. During this waiting time, the system continuously monitors whether the user has followed the suggested actions, such as restarting the beauty head or adjusting the usage method. If no user action is detected within the preset waiting time, the system will automatically enter standby mode or shut down. In standby mode, the beauty device maintains a low power consumption state so that the user can use it again at any time; while shutting down will completely stop the beauty device from working, saving energy.

[0161] The design of preset waiting time and automatic entry into standby mode or shutdown fully considers various situations that users may encounter. On the one hand, it avoids the beauty device remaining in an abnormal state for an extended period due to the user's temporary absence or lack of timely response, reducing energy consumption and potential safety risks. On the other hand, automatically entering standby mode or shutting down also reflects the device's intelligence and user-friendliness, eliminating the need for complex manual operations and improving ease of use. Simultaneously, this design also helps extend the lifespan of the beauty device, reducing wear and tear caused by prolonged unnecessary use.

[0162] In summary, the addition of steps S112 and S113 further improves the protection method of this embodiment, enabling the beauty device to better interact with users and provide a higher quality and more intelligent user experience while ensuring user safety.

[0163] Please refer to Figure 7 In one embodiment of this example, in Figure 3Based on the provided technical solution, the method is further optimized before step S108. Specifically, the method further includes steps S107.5-S107.6. The purpose of these steps is to further understand the specific condition of the skin after confirming contact between the beauty head and the skin, and to dynamically adjust the key duration parameters (i.e., the second duration threshold) used in subsequent control operations based on the skin condition. This allows the beauty device to adapt to different skin conditions more accurately and personally, improving the safety and effectiveness of its use. Explanations of terms identical or corresponding to those in the above embodiments will not be repeated here.

[0164] S107.5, Detect the condition of the skin.

[0165] It should be noted that, on the one hand, the detection method can be sensor detection. Beauty devices can be equipped with various types of sensors to detect skin condition. For example:

[0166] Temperature sensor: Capable of measuring the skin surface temperature in real time. Different skin types (such as oily skin, dry skin, and sensitive skin) may exhibit different temperature changes under normal conditions and when exposed to external stimuli (such as heating from a beauty device). For example, sensitive skin may heat up more rapidly when heated.

[0167] Humidity sensor: Used to detect the humidity of the skin surface. Skin humidity reflects the skin's water content; dry skin typically has lower humidity, while oily skin has relatively higher humidity. Skin humidity affects the rate of heat conduction and dissipation when the beauty device is heating.

[0168] Skin resistance sensor: The skin's resistance value is related to factors such as the thickness of the stratum corneum and its moisture content. Different skin types have different resistance values, and measuring skin resistance can help determine skin type and condition.

[0169] On the other hand, the detection method can be image recognition technology (which requires the beauty device to be equipped with a camera): using the camera to take images of the skin surface, and then using image analysis algorithms to identify features such as skin texture, pore size, and pigmentation distribution, thereby determining the skin type (such as normal skin, combination skin, etc.) and whether there are any abnormal conditions such as inflammation or allergies.

[0170] S107.6. Match the corresponding second duration threshold according to the skin condition.

[0171] It's important to note that the second time threshold plays a crucial role in subsequent control operations. It controls the cooling time of the beauty device under different skin conditions. Specifically, the second time threshold is the minimum cooling time required after the beauty head leaves the skin to ensure that it won't burn the skin due to excessive temperature upon re-contact.

[0172] Suppose a beauty device detects through sensors that the user's skin is dry, with low moisture, normal initial temperature, and no abnormalities. Based on preset matching rules, the control device will set the second duration threshold to 4 seconds. During subsequent use, after the beauty head leaves the skin, at least 4 seconds must be waited before restarting the heating operation. This is longer than the 3-second threshold for oily skin. During this waiting period, even if the head touches the skin again, it will not heat the skin, thus ensuring safety and reducing the risk of burns. Of course, this specific duration is just an example and can be adjusted based on actual test results.

[0173] Please refer to Figure 8 In one embodiment of this invention, during the skin heating process of the beauty device, a parallel process flow S301-S302 is added. The main purpose is to dynamically adjust the cooling time threshold (i.e., the second time threshold) based on the actual displacement of the beauty head. This is because when the detected displacement of the beauty head is too small, it means that there may be problems such as the heating area being too concentrated or the local skin being heated for too long. In this case, by increasing the waiting time for cooling, it is possible to effectively avoid damage to the local skin due to excessive heating, while optimizing the heating effect, making the heat distribution more uniform, and improving the overall quality and safety of beauty care.

[0174] S301. During the process of heating the skin, detect whether the displacement of the beauty head is less than a preset displacement threshold; if not, continue to execute S301; if yes, execute S302.

[0175] It should be noted that a displacement sensor can be installed on the beauty head of the beauty device. Common types include potentiometer-type displacement sensors, Hall effect displacement sensors, or optical displacement sensors.

[0176] Potentiometer-type displacement sensor: This type of sensor converts the mechanical displacement of the beauty head into a change in the resistance value of a potentiometer, and then uses a circuit to convert the resistance change into a voltage or current signal, thereby measuring the amount of displacement of the beauty head. This type of sensor has a simple structure and low cost, but its accuracy is relatively limited.

[0177] Hall effect displacement sensor: Based on the Hall effect, when the beauty head moves, it causes a change in the magnetic field, and the voltage signal output by the Hall element changes accordingly. The displacement of the beauty head can be determined by measuring the change in the voltage signal. It features high sensitivity and fast response speed.

[0178] Optical displacement sensors: These sensors measure displacement using the principles of light reflection or interference. For example, a laser beam is emitted onto the surface of a beauty head, and the displacement is calculated by detecting changes in the position of the reflected light. Optical displacement sensors offer high accuracy and a large measurement range, but are relatively expensive.

[0179] Understandably, to achieve real-time monitoring, the displacement sensor continuously collects the displacement data of the beauty head at a high frequency, such as 10-100 times per second or even higher, to ensure that any minute movement of the beauty head can be captured in a timely manner. The collected displacement data is transmitted to the control device in real time for processing and analysis.

[0180] The preset displacement threshold was determined based on extensive experimental data and skin safety standards. Taking into account different beauty modes, skin types, and the design requirements of the beauty device, multiple tests and optimizations were conducted to find a suitable displacement range that ensures both beauty effects and avoids skin damage. For example, for general facial beauty care, the preset displacement threshold might be set at 5 mm. If the displacement of the beauty head is less than this value, it is considered too small, and the cooling time needs to be adjusted.

[0181] After receiving real-time displacement data from the displacement sensor, the control device immediately compares it with a preset displacement threshold. If the current displacement of the beauty head is not less than the preset displacement threshold, the control device continues to execute step S301, continuously monitoring and comparing the displacement to form a cyclic monitoring process, ensuring that any abnormal changes in displacement can be detected in a timely manner. Only when the detected displacement of the beauty head is less than the preset displacement threshold will the control device determine that the condition is met and then execute step S302.

[0182] S302, Increase the second duration threshold.

[0183] It should be noted that when the displacement of the beauty head is determined to be too small, the control device will adjust the second duration threshold according to a preset algorithm. For example, a linear adjustment algorithm can be used, determining the adjustment range based on how much the displacement is less than the preset threshold. Assuming the preset displacement threshold is 5 mm, when a displacement of 3 mm is detected (2 mm less than the preset threshold), the second duration threshold can be increased proportionally, such as by 20%. The specific adjustment ratio can be optimized and adjusted based on actual experiments and user feedback.

[0184] By dynamically adjusting the cooling time, heat can be distributed more evenly on the skin, promoting the absorption of beauty ingredients and enhancing the effectiveness of beauty treatments. For example, in beauty procedures such as spot removal and skin whitening, even heating helps activate skin cell metabolism and enhance the efficacy of beauty products.

[0185] Moreover, it avoids the problem of excessive local skin heating caused by insufficient displacement of the beauty head, reducing the risk of skin burns, allergies, and other issues, and providing users with a safer and more reliable beauty care experience.

[0186] In addition, adjusting the cooling time appropriately can reduce the energy consumption of the beauty device, extend its service life, and lower maintenance costs.

[0187] Although this invention uses terms such as "beauty device" and "heating" frequently, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
