[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the temperature control method, device and system of a beauty instrument proposed by the present invention, its specific implementation, structure, features and effects are described in detail as follows in combination with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.

[0022] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0023] The following is a detailed description of a temperature control method, device and system for a beauty instrument provided by the present invention in conjunction with the accompanying drawings.

[0024] See also Figure 1 , which shows a flow chart of a temperature control method of a beauty instrument provided by an embodiment of the present invention.

[0025] 1. The temperature sensor provided in the beauty instrument is used to monitor the skin surface temperature of the user in real time. The user of the embodiment of the present invention refers to the object of application and implementation of the beauty instrument, that is, the user, which can be a person or an animal, rather than the staff operating the beauty instrument. Of course, in some scenarios, the user, that is, the user, may be the same person as the person operating the beauty instrument. Taking a person as an example, the skin surface of the embodiment of the present application can be any part of the human body that needs beauty treatment, generally referring to the facial skin, and in some scenarios, it can also be other parts of the skin, such as the hands, waist, abdomen or back. In general, the temperature sensor of the embodiment of the present invention is provided on the beauty instrument body, which is convenient for monitoring the temperature while using the beauty instrument. It is not excluded that the temperature sensor is provided separately in some specific scenarios, or is provided on other instruments and equipment used in conjunction with the beauty instrument. In addition, there are also requirements for the temperature sensor itself, which needs to be able to measure the temperature normally in the use environment of the beauty instrument. For example, in how to avoid the influence of the mist sprayed by the beauty instrument on the temperature measurement, the embodiment of the present invention can use an infrared thermometer with a certain penetration ability.

[0026] 2. Analyze the changes in the skin surface temperature and the output power of the beauty instrument in time series to obtain the skin temperature change parameters of the user. The temperature data collected by the temperature sensor has a time series. The embodiment of the present invention analyzes the changes in the skin surface temperature and the output power of the beauty instrument in time series to obtain the skin temperature change parameters of the user. From the start of the beauty instrument to the constant temperature range, the output temperature of the beauty instrument changes. The output temperature of the beauty instrument is directly affected by the output power of the beauty instrument. Therefore, the change in the output power of the beauty instrument can reflect the change in the output temperature of the beauty instrument.

[0027] Specifically, the skin surface temperature change parameter of the user at the i-th moment is: the ratio of the first difference to the second difference. The first difference here is the difference between the skin surface temperature of the user at the i-th moment and the skin surface temperature of the user at the i+1st moment; the second difference here is the difference between the output power of the beauty instrument at the i-th moment and the output power of the beauty instrument at the i+1st moment; where i is a positive integer; the skin surface temperature of the user at all moments before the current moment and the output power of the beauty instrument at all moments are traversed to obtain the skin temperature change parameter of the user during the use of the beauty instrument.

[0028] 3. Analyze the skin temperature change parameters of the user at all adjacent moments in the time series to obtain the skin tolerance parameters of the user during the use of the beauty instrument. Specifically: group the adjacent moments in the time series into a group, calculate the absolute value of the change rate of the skin temperature change parameter in each group; then traverse all groups, calculate the average of the absolute values ​​of the change rate of the skin temperature change parameters of all groups, and use this average as the skin tolerance parameter of the user during the use of the beauty instrument.

[0029] 4. When the skin tolerance parameter is greater than the first threshold, the current output power of the beauty instrument is adjusted; the first threshold in the embodiment of the present invention is 0.2. In actual application scenarios, different users, different parts of the skin, and different beauty instruments have different setting values ​​for the first threshold.

[0030] Collect the skin tolerance parameters in the previous stage as a consideration for the temperature adjustment or output power adjustment of the beauty instrument in the next stage. The moment when the skin tolerance parameter in the previous stage is greater than the first threshold is recorded as moment q, where q is a positive integer. The ratio of the skin temperature at moment q to the median of the optimal suitable temperature range is used to represent the progress of the user from the beginning of using the beauty instrument to entering the optimal temperature. The ratio of the skin temperature change value of the user in the previous stage to the duration of the previous stage is used to represent the skin sensitivity of the user. According to the skin tolerance parameters, the progress of the user from the beginning of using the beauty instrument to entering the optimal temperature, and the skin sensitivity of the user, determine the state change parameters when the user feels uncomfortable due to the temperature.

[0031] According to the current output power of the beauty instrument and the state change parameter when the user feels uncomfortable due to temperature in the previous stage, the target output power of the beauty instrument is obtained; and the current output power of the beauty instrument is adjusted to the target output power;

[0032] 5. During the use of the beauty instrument, repeat steps 1-4 above to continuously monitor the user's skin temperature.

[0033] The embodiment of the present invention monitors the skin temperature change data of the user in real time during the use of the beauty instrument, and dynamically adjusts the output power of the beauty instrument in combination with the real-time skin temperature, thereby accurately adjusting the output temperature of the beauty instrument, thereby ensuring the user's safety while improving the user experience.

[0034] Another embodiment of the present invention aims to solve the defect that the time required for users to start up and enter the effective use state when using the beauty instrument is too long, thus affecting the user experience. The embodiment of the present invention monitors the changes in the user's facial skin temperature in real time through a built-in temperature sensor, and analyzes the temperature range suitable for the user based on this, and then quickly adjusts the output power of the device to accurately control the mist temperature, so that the user can enter the effective use state faster and more smoothly, thereby improving the user's overall use experience. The embodiment of the present invention is specifically:

[0035] By installing a temperature sensor on the beauty instrument, the user's facial skin temperature data is obtained during use. Skin temperature refers to skin temperature. Based on these skin temperature data, the overall changes in the user's facial skin temperature are deeply analyzed, and the change parameters of the facial skin temperature during the user's use are calculated. Subsequently, according to these parameters, the output power of the beauty instrument is accurately adjusted to ensure that the user's facial skin temperature can safely and stably reach the optimal and suitable temperature, while effectively avoiding the occurrence of burns.

[0036] The specific scenario targeted by the embodiment of the present invention is that there is a transition stage between the beauty instrument starting to work and the user's facial skin temperature reaching the optimal and suitable state. In order to improve the user's maintenance experience, during this stage, it is necessary to continuously monitor the user's facial skin temperature during use and carefully analyze its changing state. Subsequently, based on these changing parameters, the output power of the beauty instrument is precisely regulated to ensure that the user's facial skin temperature can reach the optimal and suitable state smoothly and safely.

[0037] Step S1: Install a temperature sensor on the detection device to detect the user's facial temperature data during use.

[0038] An infrared thermometer is installed under the beauty instrument nozzle device (in order to avoid the mist sprayed by the beauty instrument from interfering with the detection results, a thermometer with a certain penetration ability is selected here). Taking the anti-scalding beauty spray device of patent application number 2022203131175 as an example, the infrared thermometer is installed in the adjacent Figure 1 Below the connection portion shown by the component marked 7 in the figure and the component marked 9 in the figure, so as to further reduce the influence of fog on the detection results.

[0039] Before using the beauty instrument, the user's facial information is detected to obtain the adaptation interval T of the user's facial skin temperature, and the maximum temperature of the mist of the user's beauty instrument is set before the user performs beauty treatment.

[0040] After the beauty instrument is turned on, it will start working immediately. At this time, adjust the relative position between the beauty instrument and the user to ensure that the thermometer installed on the beauty instrument can accurately monitor the skin temperature of the user's face. At the same time, adjust the direction and position of the beauty instrument nozzle to ensure that the sprayed mist can fully and effectively cover the user's face.

[0041] Then, the sensor on the beauty instrument immediately starts to monitor the skin temperature of the user's face in real time. And transmit these monitoring data to the temperature control system of the beauty instrument in real time and accurately.

[0042] Finally, the temperature control system of the beauty instrument will sort the received data according to the monitoring time and conduct detailed analysis and processing of the data.

[0043] Step S2: Analyze the temperature change of the user's face according to the detection data and adjust the output power of the device in time.

[0044] a. Based on the detection data of the user's facial skin temperature, the system analyzes the changes in the user's skin temperature during the beauty process. When the beauty instrument is working, in order to provide users with better and more effective beauty effects and ensure the user's comfort during use, the mist sprayed from the nozzle will be heated, thereby improving the user's comfort and use experience.

[0045] Adjust the position of the beauty instrument to ensure that the temperature sensor installed on it can accurately monitor the user's facial skin temperature. When the beauty instrument is turned on, the liquid in its solution tank will be transported to the nozzle for atomization, and then the mist will be gently sprayed onto the user's face. At the same time, the temperature sensor immediately starts working, collecting and monitoring the user's facial skin temperature data in real time, and then uploading the monitoring data to the temperature control system. After the system receives the data, it will conduct further analysis and processing.

[0046] Therefore, the user's usage experience is evaluated by analyzing the monitoring data of the user's facial skin temperature.

[0047] Next, by conducting an in-depth analysis of the monitored data, we can obtain the user's facial temperature change parameter F during use:

[0048]

[0049] Where: F represents the change in facial temperature of the user at the i-th and i+1-th moments during use, i is the time sequence number of the user using the beauty instrument, , are the facial skin temperatures of the user at the i-th and i+1-th moments when using the beauty instrument, , are the temperatures of the heating device of the beauty instrument at the i-th and i+1-th moments when the user uses the beauty instrument, that is, the output power of the beauty instrument, It is the difference of the skin temperature of the user's face at adjacent moments during use. The difference in output power of the beauty instrument at adjacent moments during use. It is used to indicate the change of skin temperature during use. It is used to indicate the change of output power of beauty instrument during use. It is the ratio of the difference between the facial skin temperature of the user and the output power of the beauty instrument at adjacent moments during use, which indicates the relationship parameter between the facial skin temperature of the user and the output power of the device during use. The smaller the value, the less the user's skin temperature is affected by the mist temperature, and vice versa. In order to ensure that the denominator is not zero, the parameter adjustment coefficient is added to the denominator. , =0.0001.

[0050] b. Analyze the best adjustment time and identification of beauty devices during use based on the user’s data changes.

[0051] In the beauty salon, after the staff pre-treats the user's facial skin, the user will follow the instructions and lie flat on the medical bed. Then, the staff will place the beauty instrument next to the bed and start it. The solution inside the beauty instrument will quickly atomize into mist, which will be evenly sprayed through the nozzle, gently covering and penetrating the user's face, thus achieving a maintenance effect on the face.

[0052] Different skin types have different sensitivities to temperature changes caused by mist. Therefore, when testing users, the user's tolerance to skin temperature changes will be indirectly assessed based on the degree of skin temperature change. Based on this assessment result, the mist temperature or heating speed sprayed by the beauty instrument can be flexibly adjusted to better match the user's comfort and personalized beauty needs.

[0053] Furthermore, in order to fully understand the tolerance characteristics of the user's facial skin during the use of beauty instruments, it is necessary to continuously monitor the changes in facial skin temperature and analyze the tolerance parameter Q as a whole. Finally, according to the specific changes in skin tolerance, the test results will be scientifically segmented.

[0054]

[0055] Where: Q is the skin tolerance parameter of the user during the maintenance process of using the beauty instrument, is the group number formed by the adjacent moments i and i+1 when the user uses the beauty instrument (a moment group divided by the two adjacent moments i and i+1 is a group j, where j is the group number. F analyzes the two adjacent moments, so the two adjacent moments are divided into one group), The duration of operation of the beauty instrument during use; It is the temperature change parameter of the user's face during use. It is the difference between the change parameters of the adjacent moments of the face during the user's maintenance process. During normal use, the change parameters of the face skin temperature are close or similar. The value of is close to 0, so the closer the value is to 0, the normal change of the user's facial skin temperature during use. On the contrary, there is an abnormal change during the user's use of the beauty instrument, that is, the user feels uncomfortable with the temperature of the beauty instrument. In order to ensure that the denominator is not zero, add the parameter adjustment coefficient to the denominator. , =0.0001.

[0056] Set the threshold to 0.2. If the user feels uncomfortable with the temperature of the beauty instrument, the output power of the beauty instrument needs to be adjusted; otherwise, it is not necessary.

[0057] When the user uses the beauty instrument for facial beauty, the mist formed by the solution containing special ingredients released by the beauty instrument will adhere to the user's face, and then the mist will transfer heat to the user's face, causing the facial temperature to rise. As the beauty process continues, the temperature of the face will gradually change accordingly until the user's facial skin temperature stably and safely reaches the appropriate temperature, thereby providing the user with a good user experience and beauty effect. During this period, the beauty instrument starts from the initial power and continuously provides the user with warm mist within the set appropriate temperature range. When the user's facial skin temperature change parameters are monitored to be abnormal, it should be checked in time to see if there is any abnormality, and the output power and mist temperature of the beauty instrument should be adjusted accordingly to ensure that the user can enjoy a more comfortable maintenance process.

[0058] During the detection process, since the user's facial skin reacts differently to temperature changes, the tolerance parameter Q of the user's facial skin when using the beauty instrument is obtained through the previous step. If the user detects that the Q value has changed significantly while using the beauty instrument, it may mean that the user feels uncomfortable with the temperature of the mist sprayed by the current beauty instrument, so the mist temperature needs to be adjusted accordingly. Therefore, when the system detects that the Q value is abnormal, the specific time q when the abnormality occurs and the detection data information at that time should be recorded immediately, such as the facial skin temperature at adjacent times. etc. for subsequent analysis and adjustment.

[0059] For the detected abnormal data, segment processing is performed, and the data in each segment is analyzed in detail. First, the relationship between the facial skin temperature and the set optimal temperature at the end of the segment is analyzed. Based on these analyses, the overall data is further evaluated comprehensively. If it is found that the ratio between the facial skin temperature and the optimal temperature is small at this time, and the variation parameters of the facial skin temperature are also small, it means that there is a large gap between the current temperature and the optimal temperature. At this time, the output power of the beauty instrument can be appropriately increased. On the contrary, if the facial skin temperature is close to or exceeds the optimal temperature, and the variation parameters also indicate that the temperature is stabilizing or rising too fast, the output power should be reduced.

[0060]

[0061] Where: Y represents the state change parameter when the user feels uncomfortable, Q is the user's skin tolerance parameter during the process of using the beauty instrument for maintenance, It is the median of the suitable temperature range tested by the user before using the beauty instrument and its value is not 0. The skin temperature of the user's face at time q when using the beauty instrument. It is the ratio of the facial skin temperature at time q to the median of the optimal temperature range, which is used to indicate the progress of the user from starting to use the beauty instrument to reaching the optimal maintenance temperature. The larger the value, the faster the user's face adapts, and vice versa; is the change value of the user's facial skin temperature within the segment, is the length of time occupied by the current segment, It is the ratio of the change in the user's facial skin temperature within the segment to the segment duration. The larger the value, the better the user's skin sensitivity, and vice versa. Indicates the state parameter that the user may feel uncomfortable in the segment. The larger the value, the larger the output power range that the beauty instrument needs to adjust, and vice versa. The function normalizes the value.

[0062] c. Analyze the overall change parameters of the segmented data based on the user experience to obtain the range within which the output power of the beauty instrument needs to be adjusted.

[0063] When the user adjusts the power of the beauty instrument during use, the adjustment range is based on the overall change of the user's facial skin temperature in the previous stage. Through the previous steps, the overall change parameter Y of the user's facial skin temperature in the current segment when the user may feel uncomfortable has been obtained. Therefore, combined with the current output power P and parameter Y, the adjusted output power is calculated :

[0064]

[0065] Then, adjust the output power of the beauty instrument to , repeat the above steps to continue monitoring the user's facial skin temperature and obtain its overall change.

[0066] During operation, you need to pay close attention to the changes in the user's facial skin. Once you find that the user's face is obviously uncomfortable or the state parameters are beyond the normal range, you should immediately adjust the output power of the beauty instrument in time to prevent the user's face from being burned.

[0067] Step S3: Complete the temperature control adjustment of the beauty instrument according to the above process.

[0068] Through the above steps, the changes in the user's facial skin temperature during use of the beauty instrument are monitored and obtained in real time, and the power parameters that need to be adjusted for the beauty instrument are calculated accordingly. Subsequently, the output power of the beauty instrument is automatically adjusted according to these parameters to ensure that the user obtains the best comfort and beauty effect during use.

[0069] The method of this embodiment can be integrated into the beauty instrument system to detect the user's skin condition and then adjust the output power. The system first processes the user's facial skin temperature data monitored by the temperature sensor to obtain the overall change of the user's facial skin temperature. Then, the system will determine whether the output power of the beauty instrument needs to be adjusted according to the change of the user's facial skin temperature. If the system predicts that the user may feel uncomfortable during use, the output power of the beauty instrument will be adjusted accordingly; otherwise, it will remain the same to ensure the user's comfort. During the adjustment process, the system will continue to monitor the changes in the user's facial skin temperature, analyze the monitored data, and calculate the difference value of the skin temperature change during the adjustment process. If the difference value reaches or exceeds the skin temperature difference threshold when the user may feel uncomfortable before the adjustment, the system will automatically reduce the adjustment coefficient of the output power and continue to monitor; if it does not exceed, it will be adjusted according to the normal process. Once the user's facial skin temperature stably reaches the median of the safe temperature range set by the system, the system will lock the output power of the beauty instrument to prevent accidents such as burns during use.

[0070] The embodiment of the present invention monitors the changes in the user's facial temperature in real time during use through an integrated temperature sensor, and automatically adjusts the output power of the device's temperature control system accordingly, ensuring that the temperature of the mist sprayed by the beauty instrument is always maintained within a range that is satisfactory to the user, thereby significantly improving the user experience.
