[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0018] The embodiment of the present invention provides a method for precise temperature control of a hair straightener. Figure 1 , Figure 1 A flow chart of a method for precise temperature control of a hair straightener provided by an embodiment of the present invention. The method comprises the following steps: Obtaining the instantaneous heating time characteristics in the first instantaneous heating cycle of the hair straightener, and obtaining a first instantaneous heating time curve in combination with the historical records, and obtaining the required instantaneous heating time in the second cycle according to the first instantaneous heating time curve as the first instantaneous heating time; Obtain the power coefficient in the first cycle of instantaneous heating, obtain the use frequency coefficient of the hair straightener through historical records, and obtain the influence coefficient according to the power coefficient and the use frequency coefficient; The expected heating time in the second cycle is obtained, recorded as the target heating time, and the second instantaneous heating time is obtained according to the first instantaneous heating time, the influence coefficient and the target heating time; The instantaneous heating power of the hair straightener is obtained and recorded as the first instantaneous heating power. The heating power in the second period is determined in combination with the second instantaneous heating time, and the hair straightener is instantaneously heated.

[0019] It should be noted that when the hair straightener is in use, in order to ensure that it is more in line with the current usage environment, in the first cycle of instant heating, the hair straightener is still instantaneously heated according to the originally set instant heating power, so as to collect data that is more in line with the actual usage status. At the same time, it can also ensure that the heating power will not be blindly adjusted in the first cycle, causing the hair straightener to overheat.

[0020] Based on a precise control method for instantaneous temperature control of a hair straightener provided by an embodiment of the present invention, the heating power can be appropriately adjusted according to the actual use status and historical records of the hair straightener in the above manner, and blindly adjusting the instantaneous heat power to cause temperature overshoot will not occur, thereby reducing excessive thermal stress on electronic components and minimizing the impact on the service life of the hair straightener.

[0021] In one embodiment, the instantaneous heating time characteristics of the hair straightener in the first instantaneous heating cycle are obtained, and the first instantaneous heating time curve is obtained in combination with the historical records, and the required instantaneous heating time in the second cycle is obtained according to the first instantaneous heating time curve, as the first instantaneous heating time, including: Obtaining a temperature before instant heating and a target instant heating temperature in a first instant heating cycle of the hair straightener, recording them as a first initial temperature and a first target instant heating temperature, respectively, obtaining a first heating temperature interval according to the first initial temperature and the first target instant heating temperature, and recording a heating time corresponding to the first heating temperature interval as a first time; Extracting the heating time corresponding to the first heating temperature interval from the historical data in the order of use time as a historical heating time set, and drawing a first instantaneous heating time curve according to the data in the historical heating time set and the first time; Calculate the slope of the first instantaneous heating time curve and record it as an influencing factor, obtain the temperature of the hair straightener when it is not instantaneously heated and the target instantaneous heating temperature in the next cycle, record them as the second initial temperature and the second target instantaneous heating temperature, respectively, and obtain the second heating temperature range according to the second initial temperature and the second target instantaneous heating temperature; The instantaneous heating power of the hair straightener is obtained, recorded as the first instantaneous heating power, and the time required for the hair straightener to heat from the second initial temperature to the second target instantaneous heating temperature is inquired according to the preset first instantaneous heating power corresponding temperature heating schedule, recorded as the initial instantaneous heating time; The first instant heating time is obtained according to the initial instant heating time and the influencing factor.

[0022] It should be noted that the preset first instantaneous heating power corresponding to the temperature heating schedule is set by professionals according to the actual situation and is not specifically limited; in addition, the first instantaneous heating time can be obtained according to the initial instantaneous heating time and the influencing factor through the following formula: , where is the initial instantaneous heating time, is the impact factor, It is the first instantaneous heating time.

[0023] In one implementation, through the above method, by combining the instantaneous heat time characteristics and historical records, the system can more accurately predict and adjust the instantaneous heat time, making temperature control more precise and subsequent power adjustment more accurate.

[0024] In one implementation, obtaining the power factor in the first cycle of instantaneous heating includes: Obtain the power supply current value of the hair straightener at different times in the first cycle, and calibrate the current value as , Indicates the number of times the power supply current value of the hair straightener is connected at different times in the first cycle, , is the actual current value obtained The number of is a positive integer; Calculate the current value in the first cycle The standard deviation of , the calculation formula is:

[0025] in, is the average value of the power supply current value connected to the hair straightener at different times in the first cycle, and the expression obtained is: .

[0026] It should be noted that the current values ​​of the power supply connected to the hair straightener at different times in the first cycle can be directly obtained through the system inside the hair straightener; when the hair straightener is in use, the larger the power supply coefficient is, the more unstable the current value of the connected power supply is. When the hair straightener is in use, the more unstable the current value of the connected power supply is, the more it is necessary to appropriately increase the instantaneous thermal power of the hair straightener. The reason is: Compensation for current fluctuations: The influence of current fluctuations: Unstable power supply current will cause fluctuations in the actual input power of the heating element, thus affecting the heating efficiency and the accuracy of temperature control.

[0027] Power compensation: By increasing the instantaneous thermal power, the power loss caused by current fluctuations can be compensated to ensure that the heating element can provide sufficient heat to maintain a stable heating effect.

[0028] Ensure heating efficiency: Temperature response speed: Unstable power supply current may cause the temperature response speed of the heating element to slow down. Properly increasing the instantaneous heating power can improve heating efficiency and shorten the time to reach the target temperature.

[0029] Constant temperature maintenance: In the case of large current fluctuations, increasing the instantaneous thermal power can help maintain a constant temperature and avoid temperature drops caused by insufficient power.

[0030] Improve system stability: Reduce temperature fluctuations: Unstable power supply current may cause temperature fluctuations. Increasing instantaneous thermal power can reduce such fluctuations and provide more stable temperature control.

[0031] Extend component life: Although increasing the power will increase instantaneous power consumption, in the long run, by maintaining a stable temperature, it can reduce the loss of heating elements caused by frequent temperature changes and extend their service life.

[0032] In one implementation, a more accurate power factor can be obtained through the above method, which can more accurately reflect the stability of the power supply connected to the hair straightener when it is in use.

[0033] In one embodiment, the use frequency coefficient of the hair straightener is obtained through historical records, and the influence coefficient is obtained according to the power supply coefficient and the use frequency coefficient, including: Obtaining an average usage time interval of the hair straightener, and dividing the average usage time interval by a preset usage time interval to obtain a usage frequency coefficient; The specific formula for obtaining the influence coefficient based on the power coefficient and the frequency coefficient is:

[0034] In the formula, is the impact index, and Respectively represent the power factor and the frequency factor, , are the proportionality coefficients of the power factor and the frequency factor, respectively, and , Both are greater than 0.

[0035] It should be noted that the preset usage time interval is set by professionals based on actual conditions and is not specifically limited.

[0036] It should be noted that when the hair straightener is in use, the smaller the frequency coefficient, the more frequently the hair straightener is used, and the instantaneous heat power of the hair straightener needs to be appropriately increased. The reason is: Frequent use leads to increased heat loss: Frequent heating and cooling: Frequent use means that the hair straightener goes through more heating and cooling cycles. This leads to increased heat loss because reheating after each cooling requires additional energy to return to the target temperature.

[0037] Thermal fatigue: Frequent temperature changes will accelerate the thermal fatigue of the heating element, causing its efficiency to gradually decrease and requiring more power to achieve the same heating effect.

[0038] Maintain constant heating performance: Compensate for performance degradation: As the frequency of use increases, the performance of the heating element may gradually decline. By increasing the instantaneous heating power, this performance degradation can be compensated to ensure that the heating speed and temperature control accuracy remain at the ideal level.

[0039] Maintain fast response: When used frequently, users require a higher response speed of the hair straightener. Increasing the instantaneous heat power can increase the response speed of the heating element to meet user needs.

[0040] Reduce user waiting time: Shorten heating time: When used frequently, users do not want to wait too long to reach the ideal temperature. Increasing the instantaneous heating power can shorten the heating time and improve the user experience.

[0041] Improved efficiency: Higher instantaneous heat power can heat the hair straightener to the target temperature more quickly, thereby improving the efficiency of use and reducing the waiting time between each use.

[0042] Ensure temperature stability: Reduce temperature fluctuations: Frequent use will cause the temperature of the hair straightener to fluctuate greatly. By increasing the instantaneous heat power, the temperature can be better controlled, fluctuations can be reduced, and a constant heating effect can be ensured.

[0043] In one implementation, through the above method, the influence index can be obtained more accurately, and the subsequent instantaneous thermal power of the hair straightener can be better adjusted.

[0044] In one embodiment, the expected heating time in the second cycle is obtained, recorded as the target heating time, and the second instantaneous heating time is obtained according to the first instantaneous heating time, the influence coefficient and the target heating time, including: Calculate the difference between the first instantaneous heating time and the target heating time to obtain a first delay time; The second instantaneous heating time is obtained according to the first delay time and the influence coefficient. The specific formula is: , where is the second delay time, is the first delay time, is the influence coefficient; The second delay time is added to the target heating time to obtain the second instantaneous heating time.

[0045] In one implementation, the first delay time and the influence coefficient are used to obtain the second instantaneous heating time through the above method. In this way, the influence of the hair straightener itself can be considered to obtain a more accurate instantaneous heating time of the second cycle, and subsequent adjustments are made based on the more accurate instantaneous heating time of the second cycle, so that the adjusted instantaneous heating power of the hair straightener is more accurate.

[0046] In one embodiment, the instantaneous heating power of the hair straightener is obtained, recorded as the first instantaneous heating power, and the heating power in the second period is determined in combination with the second instantaneous heating time, and the instantaneous heating control of the hair straightener includes: Calculate the product of the second instantaneous heating time and the first instantaneous heating power to obtain the final heating heat; The final heating amount is divided by the target heating time to obtain the second instantaneous heating power, and the second instantaneous heating power is used as the heating power in the second cycle to perform instantaneous heating control on the hair straightener.

[0047] In one implementation, through the above method, by calculating the product of the second instantaneous heating time and the first instantaneous heating power, the final heating heat is obtained, and the required heat can be accurately calculated, thereby accurately controlling the heating power. This method can ensure that each heating can reach the expected temperature and avoid overheating or insufficient heating; according to the target heating time, the final heating heat is converted into the required instantaneous heating power, which can more stably control the temperature, while avoiding the inconvenience of use or damage to the hair caused by temperature fluctuations, providing a more stable use experience.

[0048] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
