[0002] A hot air comb is an electrical tool that combines a hair dryer and a comb in one. It can quickly dry and style hair through electric heating to maximize hair protection.

[0003] Based on the different tolerance of different types of hair to heat, fine and soft hair is usually more fragile and easily damaged by high temperatures, so a lower temperature is required. Coarse or curly hair is usually more heat-resistant and may require a slightly higher temperature to achieve the desired styling effect. Choose the appropriate temperature setting according to your hair type and health condition, and pay close attention to the reaction of your hair and scalp when using a hot air comb. Choosing the right temperature can reduce irreversible health damage to your hair due to excessive temperature during use.

[0004] In this process, it is usually impossible to accurately control the high temperature selection of the hot air comb, and it can only be roughly controlled based on usage experience, which may cause the user to inadvertently select a temperature that exceeds the temperature adapted to their own hair.

[0056] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0057] Reference Figure 1 As shown, a hot air comb automatic sensing temperature warning method based on real-time monitoring includes:

[0058] Divide the hot air comb into use temperature zones, and evaluate the operation saturation of the hot air comb high temperature zone based on the operation statistics of the high temperature zone during use;

[0059] Real-time monitoring of the temperature change information at different depths of the user's hair when the hot air comb is running in the high temperature zone, analyzing the ratio of heat accumulation inside the hair in the hot air comb action area to the total input heat, and evaluating the abnormal level of heat accumulation of the hot air comb;

[0060] Real-time monitoring of the changes in the amount of charge at the part where the comb teeth touch the hair when the hot air comb is running in different temperature zones, and evaluation of the abnormal level of charge change in the hair in the area where the hot air comb is acting;

[0061] Analyze the changes in friction force on the hair ends sliding in the contact area of ​​the comb teeth and the changes in hair color when the hot air comb is running in the high temperature area, and evaluate the abnormal level of high temperature damage to the hair;

[0062] Based on the abnormal heat level of the hot air comb stack, the abnormal level of electrical change, and the abnormal level of high-temperature damage, the adaptability of the hot air comb operation in the high-temperature area to the current user is comprehensively evaluated, and a high-temperature warning is issued for the use of the hot air comb based on the evaluation results.

[0063] Reference Figure 2 As shown, the hot air comb is divided into temperature zones for use, and the operating conditions of the high-temperature zone during use are statistically analyzed to evaluate the saturation level of the high-temperature zone of the hot air comb.

[0064] The temperature zone division interval is set based on the usage specification standards of the hot air comb. The temperature zone division includes a low temperature zone and a high temperature zone. In daily use, the hot air comb is generally heated to between 130 and 200 degrees Celsius, and the temperature zone division can be performed in this range.

[0065] Acquire real-time monitoring data of the hot air comb temperature, count the total operating time when the temperature is in the high temperature zone during operation, calculate the ratio of the operating time of the hot air comb in the high temperature zone to the total power-on time, and mark it as the high temperature area operation saturation ratio. When the high temperature area operation saturation ratio is greater than the set threshold, turn on the hot air comb sensing temperature warning mode. The high temperature area operation saturation ratio is set according to the actual rated power of the hot air comb and the high temperature zone division. When the high temperature area operation saturation ratio is higher, the risk of high temperature damage to the hair caused by the hot air comb is higher.

[0066] Reference Figure 3 As shown, the temperature change information of different depths of the user's hair is monitored in real time when the hot air comb is running in the high temperature zone, the ratio of the heat accumulation inside the hair in the hot air comb action area to the total input heat is analyzed, and the abnormal level of the hot air comb pile heat is evaluated.

[0067] The standard heat retention ratio control Qst is set based on the safety specifications for the use of hot air combs. Specifically, the average hair temperature is calculated based on the retained heat, hair density, mass, and specific heat capacity, and the setting is made to determine whether it exceeds the safety standard.

[0068] The rated operating power of the hot air comb in the high temperature area is obtained, and the input heat Qit of the hot air comb in the unit detection time is calculated according to the heating efficiency. The heating efficiency can be calculated according to the historical actual heating value and the rated power, which will not be repeated here.

[0069] The length of the hot air comb teeth immersed in the hair is marked as the hair depth of the hot air comb action area, and monitoring points of the same scale are continuously set. The plane combination of all the hair from the hair root to the same height of the monitoring points is marked as a monitoring level. All the monitoring points at the same monitoring level are taken as a whole to continuously measure and monitor the temperature of the hair;

[0070] The hair density at different levels is detected, and the hair area combed by the hot air comb is obtained at the same time. The monitoring level volume differential is calculated according to the set detection point scale, the hair area combed by the hot air comb, and the hair density at different levels. The monitoring level volume differential calculation method is dV=S(l)*ρ′(l)*dl, where S(l), ρ′(l), and dl are the hair area at different levels, hair density, and the set detection point scale, respectively.

[0071] The heat of each monitoring layer is calculated according to the heat calculation formula, and the results are integrated to calculate the total retained heat inside the hair in the hot air comb action area. The specific expression is:

[0072] Qsy=∫c*ρ*ΔT(r)dV;

[0073] Where Qsy is the total retained heat, c is the specific heat capacity of hair, p is the density of hair, ΔT(r) is the change between the temperature detection result corresponding to the rth detection level and the initial temperature of the hair root, and dV is the microvolume of the monitoring level.

[0074] Calculate the difference between the ratio of the total retained heat Qsy inside the hair in the action area corresponding to the unit detection time of the hot air comb and the input heat Qit compared with the preset standard heat retention ratio, marked as the hot air comb stack thermal anomaly coefficient R SQ The specific calculation method of the thermal anomaly coefficient of the hot air comb pile is:

[0075] Reference Figure 4 As shown, the change in charge amount at the part where the comb teeth contact the hair when the hot air comb is operated in different temperature zones is monitored in real time, and the abnormal level of charge change of the hair in the area where the hot air comb is applied is evaluated.

[0076] An electrostatic force detection device is set at the connection position of the hot air comb teeth to monitor the change of the charge amount of the comb teeth contacting the hair when the hot air comb is running in the low temperature zone. Specifically:

[0077] The number of charge detection times is set, and the charge on the hair surface in the area where the comb teeth contact is calculated according to the average distance between the hot air comb teeth connection position and the hair surface during each detection and the average value of the detection results of the electrostatic force detection device;

[0078] According to the charge calculation result of each detection, a hair charge monitoring array is established when the hair is operated in a low temperature area, and is marked as a charge control array;

[0079] Obtain the change of the amount of charge on the hair when using the hot air comb in the high temperature area, and establish a monitoring array of the amount of charge on the hair when the hot air comb is used in the high temperature area based on the same calculation method as that for calculating the amount of charge on the hair in the low temperature area;

[0080] Based on the deviation change rate between the hair charge monitoring array and the charge control array when the hot air comb is running in the high temperature area, the hair charge change abnormality coefficient is calculated. The specific expression is:

[0081]

[0082] In the formula, R QC is the abnormal coefficient of hair charge variation, F hi 、r hi are the average value of the electrostatic force detected for the i-th time when running in the high temperature area, the average distance between the comb tooth connection position and the hair surface, and F li 、r li are the average value of the electrostatic force detected for the i-th time when running in the low temperature area, the average distance between the comb connection position and the hair surface, n is the set number of charge detection times, k is e is the electrostatic constant.

[0083] Continuous high temperature of hair will cause the moisture in the hair to evaporate, and the friction with the hot air comb will accumulate more static electricity. Excessive static electricity will usually cause mutual repulsion, causing the hair to become drier and more brittle. In addition, hair with static electricity is more likely to absorb dust and fine particles in the air. By evaluating the abnormal changes in hair charge, it can indirectly reflect the user's adaptability to the current operating temperature of the hot air comb.

[0084] Reference Figure 5 As shown, the changes in the friction force of the sliding hair ends in the contact area of ​​the comb teeth and the changes in hair color when the hot air comb is running in the high-temperature area are analyzed to evaluate the abnormal level of high-temperature damage to the hair.

[0085] High temperature can roughen the hair's cuticle (protective outer layer), causing it to lose elasticity, become dry and brittle, and even split or break. In addition, it can also cause the hair's natural pigments to decompose, making the hair color dull. Therefore, by detecting the roughness of the hair's cuticle and the degree of hair color change, you can indirectly assess the degree of damage caused to the hair by the current temperature of the hot air comb.

[0086] Set the number of friction force detection times, set a friction force detection device on the comb teeth of the hot air comb, record the friction force of the comb teeth passing through the hair during each detection, and calculate the average change rate of the friction force;

[0087] A high-definition image of the comb contact area is collected at each test. After image preprocessing, the color characteristics of the image are analyzed by image recognition software. The color difference quantification value ΔE of adjacent images is calculated using the three components of the Lab space, and the average change ratio of ΔE is calculated. The calculation method of ΔE is: , where ΔL, Δa, and Δb are the three components of the Lab space, namely the lab values ​​of brightness, red-green axis, and yellow-blue axis.

[0088] The average change ratio of friction force and the average change ratio of color difference quantization value are weighted and multiplied, and the calculation result is marked as high temperature damage abnormality coefficient RDG. In the formula are the average change ratio of the color difference quantization value and the average change ratio of the friction force, α and β are The weight coefficient of .

[0089] Reference Figure 6 As shown, based on the abnormal thermal level of the hot air comb stack, the abnormal level of charged change, and the abnormal level of high-temperature damage, the adaptability of the hot air comb operation in the high-temperature area to the current user is comprehensively evaluated, and a high-temperature warning is issued for the use of the hot air comb according to the evaluation results.

[0090] Determine whether the current mode is the hot air comb induction temperature warning mode. If so, obtain the calculated hot air comb stack thermal anomaly coefficient R SQ , abnormal coefficient of charge change R QC and high temperature damage abnormal coefficient R DG , R SQ , R QC , R DG The weighted comprehensive operation is performed to calculate the suitability index of the current hot air comb operating temperature for the user. The calculation expression of the suitability index is:

[0091]

[0092] In the formula, ω1, ω2, and ω3 are R SQ , R QC , R DGThe weight coefficient of .

[0093] Set the adaptability index threshold. When the adaptability index is greater than or equal to the adaptability index threshold, no processing is performed. When the adaptability index is less than the adaptability index threshold, a high temperature warning signal is issued to remind the user to lower the use temperature.

[0094] The adaptability index threshold is set by professionals in this field based on the adaptability index combined with the high temperature area demarcation of the hot air comb, the rated output power and the specific safety specification standards, and will not be repeated here.

[0095] By taking into account multiple factors such as abnormal stack heat, abnormal charging changes, and abnormal high-temperature damage, timely high-temperature warning is achieved for the use of hot air combs, reminding users to adjust the temperature in time to prevent further damage to the hair.

[0096] For further information, see Figure 7 As shown, based on the same inventive concept as the above-mentioned hot air comb automatic sensing temperature warning method based on real-time monitoring, this solution also proposes a hot air comb automatic sensing temperature warning system based on real-time monitoring, including:

[0097] A high-temperature area operation saturation evaluation module, wherein the high-temperature area operation saturation evaluation module determines whether to start the hot air comb sensing temperature warning mode according to the ratio of the operation time of the hot air comb in high-temperature operation to the total power-on time as the high-temperature area operation saturation ratio;

[0098] A hot air comb stack thermal anomaly assessment module, wherein the hot air comb stack thermal anomaly assessment module calculates the difference between the ratio of the total retained heat inside the hair in the action area corresponding to the hot air comb unit detection time and the input heat and the preset standard heat retention ratio as the hot air comb stack thermal anomaly coefficient;
