Description

Technical Field

[0001] The present application relates to the field of hair care devices, and in particular to a control method for a hair care device and a hair care device. Background Art

[0002] Hair care devices typically have different operating modes. When operating in a specific mode, the air temperature must be kept stable. Even for the same model of hair care device with different units, the air temperature should be consistent and stable when operating in the same mode. Therefore, the accuracy of the temperature control of hair care devices needs to be tested and calibrated, known as temperature calibration. However, due to uncertainties in the production process and variations in measurement at different test points, the accuracy of calibration results is low.

[0066] To improve the accuracy of air temperature calibration, the embodiments of the present application provide a control method for a hair care device and a hair care device. The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present application, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present application without inventive effort are within the scope of protection of this application. Examples of the embodiments are shown in the accompanying drawings, where identical or similar reference numerals throughout represent identical or similar elements or elements having identical or similar functions.

[0067] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or server that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products, or devices.

[0068] In order to facilitate understanding of the technical solutions and the technical effects produced by the embodiments of the present application, the embodiments of the present application explain the relevant professional terms involved:

[0069] Calibration primarily refers to the use of standard measuring instruments to verify the accuracy (precision) of an instrument. It is generally used for instruments with high precision. Calibration can also be considered calibration. Therefore, it can be considered to encompass both of these aspects.

[0070] NTC: Negative Temperature Coefficient, refers to the phenomenon and material of thermistors with a negative temperature coefficient, in which the resistance decreases exponentially as the temperature rises.

[0071] Open-loop control and closed-loop control: Open-loop control refers to a control method in which the input does not depend on the output; while closed-loop control refers to a control method in which the output is fed back to the input, thereby affecting the input.

[0072] The conduction power ratio is the ratio of the number of half-waves conducted in the first signal subunit and / or the second signal subunit to the total number of half-waves of a preset number of AC waves (ie, twice the preset number).

[0073] Proportional Integral Derivative control, also known as PID control, is a control method that uses a given value and the actual output value to form a control deviation. This deviation is linearly combined using proportional, integral, and differential equations to form a control variable, thus controlling the controlled object. Conventional PID controllers are linear controllers.

[0074] Figure 1This is a flowchart of a control method for a hair care device provided by an embodiment of the present application. The present application provides method operation steps as described in the embodiment or flowchart, but may include more or fewer operation steps based on conventional or non-creative work. The order of steps listed in the embodiment is only one way of executing the steps among many, and does not represent the only execution order. When the actual system or server product is executed, it can be executed in sequence or in parallel (for example, in a parallel processor or multi-threaded processing environment) according to the method shown in the embodiment or the accompanying drawings. Please refer to Figure 1 A control method for a hair care device provided in an embodiment of the present application may include the following steps:

[0075] S110: When the hair care device is operating in a preset state, a first temperature value of a first thermistor and a second temperature value of a second thermistor of the hair care device are obtained, where the first thermistor is used to detect the air outlet temperature of an air outlet, and the second thermistor is used to measure the ambient temperature of the hair care device.

[0076] It should be noted that the hair care device may include a heating wire and a motor. When the hair care device is in operation, the motor rotates to cause air flow to flow in from the air inlet, through the heating component to the air outlet, and finally out from the air outlet, thereby achieving hair drying or styling.

[0077] In one embodiment of the present application, the preset state may include a preset motor power and a preset heating power. When the hair care device operates in the preset state, the motor operates at the preset motor power for a predetermined time, and the heater heats at the preset heating power for a predetermined time. When operating at the preset motor power, the device provides a fixed air volume. Preferably, the preset motor power and the preset heating power are the motor power and heating power corresponding to the highest operating gear of the hair care device, respectively. Optionally, the hair care device can be operated in this preset state and air temperature calibrated before shipment.

[0078] In another embodiment of the present application, the preset state can correspond to the target operating gear of the hair care device after it is turned on or shifted. That is, when the power-on or gear-shift is detected, the hair care device operates according to the target motor power and target heating power corresponding to the target operating gear corresponding to the power-on or gear-shift. This target operating gear can be the default operating gear after power-on, or it can be any operable operating gear after the user adjusts the gear. It is feasible that after leaving the factory, the hair care device can operate in this preset state and perform air temperature calibration during actual user use. This method can cope with the aging of the device, updating the calibrated value as the device performance changes, providing users with a long-term good user experience.

[0079] Furthermore, in the above embodiment, the first temperature value of the first thermistor and the second temperature value of the second thermistor can be obtained when it is determined that the hair care device meets a preset operating condition. The preset operating condition can be a preset operating time, meaning that after the preset operating time, the air temperature at the air outlet of the hair care device can be considered to be relatively stable. The preset operating condition can also be that the change in the first temperature value does not exceed a preset value, meaning that when the change is within a preset value range, it can be understood that the fluctuation is small, and the air temperature at the air outlet can be considered to be relatively stable.

[0080] In an embodiment of the present application, the first thermistor and the second thermistor are both provided on the hair care device, wherein the first thermistor is located at the air outlet of the hair care device and is used to detect the outlet air temperature. Preferably, the second thermistor can be located away from the air outlet and the heating wire of the hair care device.

[0081] In the embodiment of the present application, the hair care device can calibrate the air outlet temperature value under a preset state by itself without relying on external calibration equipment.

[0082] S130: Determine a calibrated air outlet temperature value under the preset state according to the first temperature value and the second temperature value.

[0083] In the embodiment of the present application, taking into account the structural properties of the entire device and the uncertainty of production line assembly, even under the same test environment, there may be differences in the temperatures detected by the thermistors of different hair care devices of the same model. If the temperature value detected by the same thermistor is used as the calibration value, it cannot be guaranteed that the air blown out of different hair care devices of the same model in the same state will have the same temperature. Therefore, the embodiment of the present application does not directly use the first temperature value as the calibration value, but instead uses the second temperature value to compensate or correct the first temperature value. This can avoid the problem of large differences in thermistor detection values ​​of different hair care devices of the same model, thereby improving the accuracy of temperature calibration.

[0084] In one embodiment of the present application, Figure 2 As shown, determining the air outlet temperature calibration value under the preset state according to the first temperature value and the second temperature value may include the following steps:

[0085] S131: Determine a temperature compensation value according to a preset compensation parameter and the second temperature value.

[0086] S133: Obtaining a calibrated air outlet temperature value under the preset state according to the first temperature value and the temperature compensation value.

[0087] For example, the first temperature value is set to X, the second temperature value is set to Y, and the outlet temperature (i.e., the first temperature value) detected by the first thermistor is compensated by the ambient temperature. The target temperature value Z can be obtained as shown in formula (1):

[0088] Z=Xa*Y, where a is a constant; (1)

[0089] Wherein, a is a preset compensation parameter, and the value of a can be determined based on historical experimental data.

[0090] Furthermore, the calibrated value of the air outlet temperature under the preset state can be stored in the flash memory of the hair care device for adjusting and controlling the air outlet temperature during actual use.

[0091] In the embodiment of the present application, the air outlet temperature calibration value is obtained by compensating the air outlet temperature value measured by the first thermistor using the ambient temperature. This avoids the problem of significant differences in thermistor measurements between different devices of the same model, improves the accuracy of temperature calibration, and ensures consistent air temperature across different hair care devices of the same model in the same state. This further improves the accuracy and stability of constant temperature control in normal use. Furthermore, the embodiment of the present application allows the hair care device to self-calibrate, eliminating the need for external calibration equipment, thereby improving temperature calibration efficiency.

[0092] In another embodiment of the present application, the air outlet temperature calibration value corresponding to each operating gear of the hair care device can be determined according to the air outlet temperature calibration value in the preset state.

[0093] It is understandable that the above-mentioned preset state may correspond to one of the operating gears, or may correspond to a type of operating mode other than the operating gear in which the hair care device can work, and this application does not limit this.

[0094] Specifically, the preset proportional coefficient corresponding to the operating gear and the air outlet temperature calibration value can be multiplied to obtain the air outlet gear temperature calibration value corresponding to the operating gear. The air outlet gear temperature calibration value S can be shown as formula (2):

[0095] S=b*Z (2)

[0096] Where b is the proportional coefficient and Z is the air outlet temperature calibration value under the preset state.

[0097] The proportional coefficient corresponding to the operating gear can be determined according to a preset correspondence table between the preset state and each operating gear. Alternatively, the proportional coefficient can be determined according to the corresponding ratio between the power set in the preset state and the power corresponding to each operating gear.

[0098] Furthermore, after the air temperature calibration is completed, the air outlet gear temperature calibration value can also be stored in a preset storage space of the hair care device, such as a fixed address unit of a flash memory, so that when the hair care device is operating at the corresponding operating gear, the air outlet temperature of the air outlet can be closed-loop controlled according to the air outlet gear temperature calibration value.

[0099] In another embodiment of the present application, the method may further include:

[0100] Before the hair care device operates in a preset state, entering a temperature calibration mode of the hair care device;

[0101] And after storing the air outlet gear temperature calibration value corresponding to each of the operating gears, exiting the temperature calibration mode.

[0102] It is feasible that before the device leaves the factory, the hair care device is started and enters the temperature calibration mode, so that the hair care device can operate in a preset state, and exit the temperature calibration mode after the calibration is completed. Further, after exiting the temperature calibration mode, the temperature calibration mode can also be disabled.

[0103] Figure 3a A schematic diagram of the flow of wind temperature calibration and closed-loop control is shown in FIG. Figure 3a As shown, the air temperature calibration process in calibration mode may include: operating in open-loop mode at a fixed heating power, and when the air outlet temperature is detected to be relatively stable, recording the current air outlet NTC temperature and the ambient NTC temperature, calculating an air outlet temperature calibration value for closed-loop control based on the recorded values, and storing the air outlet temperature calibration value in Flash memory. After air temperature calibration is completed, when the hair care device is operated in a certain operating gear instead of in calibration mode, the stored air outlet temperature calibration value is used to convert the air outlet temperature calibration value corresponding to each operating gear. Based on a given control cycle, the first temperature value of the first thermistor is collected as a real-time sampled value, and the deviation between the air outlet temperature calibration value corresponding to the current operating gear and the real-time sampled value is calculated. The deviation value is input into a PID control unit for partial, differential, or integral calculation. Based on the calculation result, the output control waveform of the heating wire is adjusted to ensure that the real-time sampled value approaches the corresponding air outlet temperature calibration value.

[0104] Figure 3b Another flow chart of wind temperature calibration and closed-loop control is shown in FIG. Figure 3bAs shown, after detecting the start or shift operation, the preset time is run in open-loop mode at the default running gear at start or the corresponding running gear after the shift. At the end of the preset time, the air outlet NTC temperature and the ambient NTC temperature are recorded, and based on this, the air outlet temperature calibration value for closed-loop control is calculated, and the air outlet temperature calibration value is stored in Flash. If the start or shift is not detected or the running time after the start or shift is less than the preset time, based on the given control cycle, the deviation between the air outlet temperature calibration value corresponding to the current running gear and the real-time sampling value is calculated, and the deviation value is input into the PID control unit for partial, differential or integral calculation. According to the calculation result, the output control waveform of the heating wire is adjusted so that the real-time sampling value tends to the corresponding air outlet temperature calibration value.

[0105] Figure 4 A schematic diagram of a process for controlling the power of the heating wire according to the temperature calibration value of the air outlet gear is shown. Figure 4 As shown, in the closed-loop control process, the air outlet gear temperature calibration value corresponding to the current operating gear is first determined, and the air outlet gear temperature calibration value and the real-time temperature value collected by the thermistor at the air outlet are input into the PID control unit. The PID control unit calculates the open wave power ratio of the heating wire according to the air outlet gear temperature calibration value and the real-time temperature value, so that the heating wire adjusts the heating power according to the open wave power ratio, thereby affecting the temperature of the air at the air outlet. The thermistor continues to collect the temperature of the air outlet in real time, and inputs it into the PID control unit again together with the air outlet gear temperature calibration value, thereby forming a complete cycle control.

[0106] The control process is described in detail below. In an embodiment of the present application, the hair care device includes a body, an air inlet and an air outlet provided on the body, a first heating unit and a second heating unit provided in the body for generating heat, and a temperature detection unit for detecting the actual air outlet temperature of the air outlet;

[0107] Specifically, the hair care device achieves the purpose of hot blowing by generating heat through the first heating unit and the second heating unit; wherein, the cold air entering through the air inlet of the hair care device is heated after flowing through the first heating unit and the second heating unit, and then the hot air is output from the air outlet of the hair care device.

[0108] Exemplarily, the hair care appliance may be a hair dryer;

[0109] Specifically, the first heating unit and the second heating unit can both be heating wires, heating sheets, etc.

[0110] like Figure 5As shown, in order to improve the accuracy and stability of constant temperature control in normal use mode, the control method provided in the embodiment of the present application may further include the following steps S201, S203, S205, and S207 after the step of determining the air outlet temperature calibration value corresponding to each operating gear of the hair care device based on the air outlet temperature calibration value, which are described in detail below.

[0111] S201: Determine the current conduction power ratio according to the air outlet temperature calibration value and the actual air outlet temperature.

[0112] It should be noted that, in the embodiment of the present application, the air outlet temperature calibration value can be set according to different gears of the hair care device, and different gears have different air outlet temperature calibration values;

[0113] Specifically, when a power-on or gear-shift signal of the hair care appliance is received, the air outlet gear temperature calibration value corresponding to the current gear of the hair care appliance can be determined; that is, the power-on or gear-shift signal of the hair care appliance carries the air outlet gear temperature calibration value of the hair care appliance;

[0114] Each gear corresponds to a cycle. Correspondingly, the current conduction power ratio can be determined based on the air outlet gear temperature calibration value of the current cycle and the actual air outlet temperature detected by the temperature detection unit. The following method can be used:

[0115] Specifically, in the embodiment of the present application, the method for determining the current conduction power ratio includes: step S301 and step S303, as described below:

[0116] S301: Determine the temperature difference between the air outlet temperature calibration value and the actual air outlet temperature.

[0117] In the embodiment of the present application, before determining the temperature difference between the air outlet gear temperature calibration value and the actual air outlet temperature, the method further includes obtaining the actual air outlet temperature of the first heating unit and the second heating unit in the current gear, that is, in the current cycle;

[0118] Specifically, the actual outlet air temperature of the hair care device may be the actual temperature of the air input through the air inlet after being heated by the first heating unit and / or the second heating unit and then output through the air outlet. Correspondingly, the actual outlet air temperature may be detected by a temperature detection unit provided at the air outlet.

[0119] In the embodiment of the present application, a difference can be made based on the air outlet gear temperature calibration value of the first heating unit and the second heating unit corresponding to the current gear and the actual air outlet temperature; the temperature difference between the air outlet gear temperature calibration value and the actual air outlet temperature can be obtained;

[0120] S303: Calling a preset proportional-integral-differential control algorithm to calculate the temperature difference and obtain the current conduction power ratio.

[0121] In the embodiment of the present application, the preset proportional integral derivative control algorithm may be a PID control algorithm;

[0122] That is, the PID control algorithm can be called to calculate the temperature difference and obtain the current conduction power ratio;

[0123] Specifically, the following calculation model 1 can be used to calculate the current conduction power ratio;

[0124] Model 1:

[0125] Where U(t) represents the conduction power ratio; Error represents the temperature difference between the air outlet temperature calibration value and the actual air outlet temperature; K p represents the proportional coefficient; T represents the differential or integral time constant;

[0126] Specifically, in the embodiment of the present application, the temperature difference between the outlet temperature calibration value and the actual outlet temperature in the current cycle is substituted into the above calculation model, and the current conduction power ratio can be obtained by performing proportional, integral and differential calculations.

[0127] In the embodiment of the present application, the conduction power ratio of the hair care device when it is in each gear position can be calculated using the above method.

[0128] S203: Determine the current half-wave conduction number corresponding to the current conduction power ratio based on the current conduction power ratio and a preset number; the preset number is the number of all AC waves corresponding to the two heating units in a single cycle.

[0129] It should be noted that, in the embodiment of the present application, the AC wave may be an output wave of the hair care device, wherein each AC wave may include a positive half-wave and a negative half-wave;

[0130] Specifically, the first heating unit and the second heating unit can be controlled by a first signal subunit corresponding to the first heating unit and a second signal subunit corresponding to the second heating unit; accordingly, the sum of the number of AC waves corresponding to the first signal subunit and the number of AC waves corresponding to the second signal subunit in a single cycle is a preset number;

[0131] Exemplarily, the number of AC waves corresponding to the first heating unit is equal to the number of AC waves corresponding to the second heating unit.

[0132] In the embodiment of the present application, the conduction power ratio is the ratio of the number of half-waves conducted in the first signal subunit and / or the second signal subunit to the total number of half-waves of a preset number of AC waves (i.e., twice the preset number);

[0133] For example, the conduction power ratio may be described in percentage, such as a conduction power ratio of 25%, 50%, . . . 100%.

[0134] Specifically, the conduction power corresponding to the current conduction power ratio may be the operating power of the first heating unit and the second heating unit;

[0135] In the embodiment of the present application, the shift signal and the power-on signal carry the air outlet gear temperature calibration values ​​of the first heating unit and the second heating unit; correspondingly, the current conduction power ratio can be calculated by the air outlet gear temperature calibration value and the actual air outlet temperature of the current cycle;

[0136] Specifically, a preset proportional-integral-differential control algorithm can be used for closed-loop control, wherein the proportional-integral-differential control can be: a control deviation is formed according to a given value and an actual output value, and the deviation is linearly combined according to proportion, integration and differentiation to form a control quantity to control the controlled object.

[0137] In the embodiment of the present application, after the current conduction power ratio is obtained, the number of half-wave conduction of the AC wave corresponding to the current conduction power can be obtained according to the relationship between the current conduction power ratio and the preset number;

[0138] Specifically, the number of half waves of a preset number of AC waves may be first obtained, that is, a number that is twice the preset number;

[0139] Multiply the current conduction power ratio by 2 times the preset number to get the current half-wave conduction number corresponding to the current conduction power ratio;

[0140] For example, if the preset number of AC waves is 50, the AC wave includes 100 half waves, wherein the positive half wave and the negative half wave each include 50 half waves;

[0141] If the current conduction power ratio is 25%, the current half-wave conduction number is 100*25%=25;

[0142] S205: Determine the current conduction strategy according to the current half-wave conduction number and the preset number.

[0143] In the embodiment of the present application, the current conduction strategy may be a conduction mode of controlling the AC wave to conduct half-wave conduction;

[0144] Specifically, it may include a half-wave distribution method and a conduction method for a preset number of AC waves corresponding to the two heating units in the current cycle. Correspondingly, after the AC wave adopts the current conduction strategy to perform half-wave conduction, the first heating unit and the second heating unit operate at a conduction power corresponding to the current conduction power ratio; in the present application, the half-wave conduction method adopts the current conduction strategy, so that the power fluctuation of the first heating unit and the second heating unit during operation is small, and further the temperature control of the hair care device heated by the first heating unit and the second heating unit is more stable.

[0145] In the embodiment of the present application, the current conduction strategy includes a half-wave allocation rule and a half-wave conduction rule; wherein the half-wave allocation rule can be an allocation rule for respectively allocating the number of half-waves required to be turned on to the AC wave corresponding to the first heating unit and / or the second heating unit;

[0146] The half-wave conduction rule may be a conduction rule for conducting half-wave conduction according to a preset method on the number of half waves in the AC wave allocated to the first heating unit or the second heating unit.

[0147] Specifically, in the embodiment of the present application, the steps of the method for determining the current conduction strategy include: steps S401, S403 and S405, as described below:

[0148] S401: Determine a target half-wave allocation rule from preset half-wave allocation rules according to the current half-wave conduction number and a preset number.

[0149] In the embodiment of the present application, when determining the target half-wave allocation rule, the target half-wave allocation rule can be determined from the preset half-wave allocation rules according to the proportional relationship between the current half-wave conduction number and the preset number;

[0150] Exemplarily, if the ratio between the current half-wave conduction number and the preset number is less than 1 / 4, the target half-wave allocation rule may be the first half-wave allocation rule; wherein, the first half-wave allocation rule may be to allocate the current half-wave conduction number to the AC wave corresponding to the first heating unit or the AC wave corresponding to the second heating unit.

[0151] S403: performing half-wave allocation processing on the current half-wave conduction number based on the target half-wave allocation rule to obtain a first conduction half-wave number allocated to the first heating unit and a second conduction half-wave number allocated to the second heating unit.

[0152] In the embodiment of the present application, the sum of the first conduction half-wave number and the second conduction half-wave number is the current conduction half-wave number;

[0153] Specifically, it should be noted that the current half-wave conduction number is always less than or equal to 2 times the preset number;

[0154] In the embodiment of the present application, when allocating the current half-wave conduction number using the target half-wave allocation rule, the magnitude relationship between the current half-wave conduction number and the preset number can be determined;

[0155] Specifically, it can be determined whether the current half-wave conduction number is less than or equal to a preset number;

[0156] In one embodiment of the present application, if the current half-wave conduction number is less than or equal to a preset number, the current half-wave conduction number or half of the preset number is determined as the first conduction half-wave number, and the difference between the current half-wave conduction number and the first conduction half-wave number is determined as the second conduction half-wave number;

[0157] Specifically, if the current half-wave conduction number is determined as the first conduction half-wave number, the second conduction half-wave number may be 0;

[0158] If half of the preset number is used as the first conduction half-wave number, the second conduction half-wave number can be the difference between the current half-wave conduction number and 1 / 2 of the preset number;

[0159] In the embodiment of the present application, if the current half-wave conduction number is less than or equal to half of the preset number, the current half-wave number may be determined as the first conduction half-wave number;

[0160] If the current half-wave conduction number is greater than half of the preset number and less than or equal to the preset number, half of the preset number can be used as the first conduction half-wave number.

[0161] For example, when the preset number is 50, that is, when the total number of positive half-waves and negative half-waves of the AC wave is 100, if the current half-wave conduction number is less than or equal to 25, the current half-wave conduction number is determined as the first conduction half-wave number;

[0162] If the current half-wave conduction number is greater than 25 and less than or equal to 50, half of the preset number, that is, 25, is used as the first conduction half-wave number.

[0163] In another embodiment of the present application, if the current half-wave conduction number is greater than a preset number, the preset number or half of the preset number is determined as the first conduction half-wave number, and the difference between the current half-wave conduction number and the first conduction half-wave number is determined as the second conduction half-wave number;

[0164] In the embodiment of the present application, if the preset number is determined to be the first conduction half-wave number, the second conduction half-wave number is the current half-wave conduction number minus the preset number;

[0165] If half of the preset number is determined as the first conduction half-wave number, the second conduction half-wave number is the current half-wave conduction number - 1 / 2 of the preset number;

[0166] In the embodiment of the present application, if the current half-wave conduction number is greater than the preset number and less than or equal to 3 / 2 times the preset number, half of the preset number can be determined as the first conduction half-wave number;

[0167] If the current half-wave conduction number is greater than 3 / 2 times the preset number and less than or equal to 2 times the preset number, the preset number can be determined as the first conduction half-wave number;

[0168] For example, when the preset number is 50, that is, the total number of positive half-waves and negative half-waves of the AC wave is 100, if the current half-wave conduction number is less than or equal to 75, half of the preset number, that is, 25, is used as the first conduction half-wave number;

[0169] If the current half-wave conduction number is greater than 75 and less than or equal to 100, the preset number, that is, 50, can be used as the first conduction half-wave number.

[0170] S405: Determine a first half-wave conduction rule associated with the first conduction half-wave number and a second half-wave conduction rule associated with the second conduction half-wave number, so that the conduction half-waves in the same cycle are dispersedly output to the first heating unit and the second heating unit.

[0171] In an embodiment of the present application, the following method may be used to determine the first half-wave conduction rule associated with the first conduction half-wave number and the second half-wave conduction rule associated with the second conduction half-wave number:

[0172] Compare the first conduction half-wave number and the second conduction half-wave number with a preset number, respectively, to obtain a first comparison result and a second comparison result;

[0173] In the embodiment of the present application, it should be noted that the first conduction half-wave number and the second conduction half-wave number are both less than or equal to a preset number;

[0174] In an embodiment of the present application, the first conduction half-wave number is compared with a preset number to obtain a first comparison result. The first comparison result may be that the first conduction half-wave number is less than or equal to half of the preset number; or the first conduction half-wave number is greater than half of the preset number and less than or equal to the preset number;

[0175] Comparing the second conduction half-wave number with a preset number to obtain a second comparison result, the second comparison result may be that the second conduction half-wave number is less than or equal to half of the preset number, specifically, the second conduction half-wave number is equal to zero or equal to half of the preset number;

[0176] Alternatively, the second conduction half-wave number is greater than half of a preset number and less than or equal to a preset number, specifically, the second conduction half-wave number is equal to the preset number;

[0177] Specifically, in an embodiment of the present application, if the current half-wave conduction number is less than or equal to a preset number, then when the first comparison result is that the first conduction half-wave number is less than or equal to half of the preset number, the second comparison result may be that the second conduction half-wave number is equal to zero or equal to half of the preset number;

[0178] If the current half-wave conduction number is greater than the preset number, then when the first comparison result is that the first conduction half-wave number is greater than half of the preset number and less than or equal to the preset number, the second conduction half-wave number is equal to zero or equal to half of the preset number.

[0179] According to the first comparison result and the second comparison result, a first half-wave conduction rule associated with the first conduction half-wave number and a second half-wave conduction rule associated with the second conduction half-wave number are determined from preset half-wave conduction rules.

[0180] In the embodiment of the present application, the first half-wave conduction rule may be a conduction mode of the first conduction half-wave number in the AC wave of the first signal subunit corresponding to the first heating unit;

[0181] The second half-wave conduction rule may be a conduction manner of the second conduction half-wave number in the AC wave of the second signal sub-unit corresponding to the second heating unit.

[0182] Specifically, based on the first comparison result, a first half-wave conduction rule corresponding to the first heating unit and associated with the first conduction half-wave number is determined from the preset half-wave conduction rule;

[0183] Based on the second comparison result, a second half-wave conduction rule corresponding to the second heating unit and associated with the second conduction half-wave number is determined from the preset half-wave conduction rule.

[0184] For example, if the first comparison result is that the first conductive half-wave number is less than or equal to half of the preset number, the first half-wave conductive rule may be to make the positive half-wave or negative half-wave of the AC wave corresponding to the first heating unit fully or partially conductive.

[0185] S207: Perform half-wave conduction processing according to the current conduction strategy, so that the first heating unit and the second heating unit operate at a conduction power corresponding to the current conduction power ratio.

[0186] In the embodiment of the present application, half-wave conduction processing is performed with the current conduction strategy, which can make the first heating unit operate alone, and can also make the first heating unit and the second heating unit operate simultaneously;

[0187] Specifically, in the embodiment of the present application, half-wave conduction processing is performed according to the current conduction strategy, so that the AC wave corresponding to the first heating unit is conducted according to the first half-wave conduction rule, and the AC wave corresponding to the second heating unit is conducted according to the second half-wave conduction rule; correspondingly, the signal conduction can be achieved based on the AC wave output by the control unit of the hair care device.

[0188] In the embodiment of the present application, performing half-wave conduction processing with the current conduction strategy may include:

[0189] When the first comparison result shows that the first conduction half-wave number is less than or equal to half of the preset number, the positive half-wave or negative half-wave of the AC wave corresponding to the first heating unit is fully or partially conducted;

[0190] Specifically, when the first comparison result shows that the first conduction half-wave number is less than or equal to half of the preset number, only the conduction half-wave number of the positive half-wave of the AC wave corresponding to the first heating unit may be set to be equal to the first conduction half-wave number; or only the conduction half-wave number of the negative half-wave of the AC wave corresponding to the first heating unit may be set to be equal to the first conduction half-wave number;

[0191] When the first comparison result shows that the first conductive half-wave number is greater than half of the preset number, the negative half-wave of the AC wave corresponding to the first heating unit is completely conductive, and the positive half-wave is completely or partially conductive.

[0192] In the embodiment of the present application, performing half-wave conduction processing with the current conduction strategy may further include:

[0193] When the second comparison result shows that the second conductive half-wave number is less than or equal to half of the preset number, the positive half-wave or negative half-wave of the AC wave corresponding to the second heating unit is turned on or off;

[0194] Specifically, when the second comparison result shows that the second conduction half-wave number is less than or equal to half of the preset number, only the conduction half-wave number of the positive half-wave or negative half-wave of the AC wave corresponding to the first heating unit may be set to be equal to the second conduction half-wave number; or only the conduction half-wave number of the positive half-wave or negative half-wave of the AC wave corresponding to the second heating unit may be set to be equal to zero.

[0195] When the second comparison result shows that the second conduction half-wave number is greater than half of the preset number, both the positive half-wave and the negative half-wave of the AC wave corresponding to the second heating unit are turned on.

[0196] Specifically, if the second comparison result shows that the second number of conduction half-waves is greater than half of the preset number, that is, if the second number of conduction half-waves is equal to the preset number, both the positive and negative half-waves of the AC wave corresponding to the second heating unit are conducted. This conduction half-wave distribution rule of the present application can make the conduction distribution of the AC wave more uniform, and ensure that the operating power of the first heating unit and the second heating unit operating based on the conduction power corresponding to the current conduction power ratio is more stable.

[0197] In the embodiment of the present application, taking the case where the positive half-wave or half-wave of the AC wave corresponding to the first heating unit is partially or fully turned on as an example, the conduction can be performed based on the relationship between the first number of turned-on half-waves and a first preset ratio of a preset number, and specifically, the following steps may be included:

[0198] Specifically, it should be noted that, in this case, the number of the first conduction half-waves is less than half of the preset number.

[0199] Determining whether the first conduction half-wave number is less than or equal to a first preset ratio of a preset number;

[0200] In the embodiment of the present application, the first preset ratio may be 1 / 4 of the preset number; if the preset number is 50, the first preset ratio of the preset number may be 50 / 4;

[0201] In one embodiment of the present application, if the first conduction half-cycle number is less than or equal to a first preset ratio of a preset number, the preset number is divided by the first conduction half-cycle number to obtain a corresponding quotient and remainder, wherein the preset number, the first conduction half-cycle number, the quotient, and the remainder are all natural numbers;

[0202] In the embodiment of the present application, if the preset number is represented by Y, the first conduction half-wave number is represented by X, the commercial number is represented by Z, and the remainder is represented by W;

[0203] Then the preset number is divided by the first conduction half-wave number to obtain the corresponding quotient and remainder. Specifically, the following calculation model 2 can be used for calculation:

[0204] Model 2: Y / 2X=Z...W;

[0205] Among them, the quotient, that is, Z, can represent the number of half-waves between two adjacent conductive half-waves;

[0206] The remainder, that is, W, can represent the redundant AC half-waves after (XW) half-waves are evenly distributed in the AC wave corresponding to the first heating unit;

[0207] The first heating unit is half-wave turned on based on the first conduction half-wave number, the preset number, the quotient and the remainder, so that the positive half-wave or negative half-wave portion of the AC wave corresponding to the first heating unit is turned on.

[0208] In the embodiment of the present application, a calculation is performed by using the first conduction half-wave number, the preset number, the quotient, and the remainder to ultimately output a conduction array, wherein the conduction array includes position information of the half-wave that can be conducted in the positive half-wave or the negative half-wave of the AC wave corresponding to the first heating unit;

[0209] The first heating unit is instructed to conduct half-wave conduction on the positive half-wave or negative half-wave of the AC wave corresponding to the first heating unit based on the conduction array;

[0210] Specifically, for example, the positive half-wave or negative half-wave of the AC wave corresponding to the first heating unit can be divided into X+1 parts, where the X+1th part can be regarded as the remainder W. By distributing W evenly among the X parts, partial conduction of the positive half-wave or negative half-wave of the AC wave corresponding to the first heating unit can be achieved.

[0211] In another embodiment of the present application, if the first conduction half-wave number is greater than a first preset ratio of a preset number, the first heating unit is half-wave conducted according to the first conduction half-wave number and the preset number, so that the positive half-wave or negative half-wave of the AC wave corresponding to the first heating unit is fully or partially conducted.

[0212] In an embodiment of the present application, if the first conduction half-wave number is greater than a first preset ratio of a preset number, a complementary calculation can be performed based on the first conduction half-wave number and half of the preset number, and a conduction array is ultimately output, wherein the conduction array includes position information of the half-wave that can be conducted in the positive half-wave or the negative half-wave of the AC wave corresponding to the first heating unit;

[0213] The first heating unit is instructed to conduct half-wave conduction on the positive half-wave or negative half-wave of the AC wave corresponding to the first heating unit based on the conduction array;

[0214] Specifically, X and Y / 2 can be complementary turned on;

[0215] For example, if the preset number is 50, that is, Y is equal to 50, then the number of AC waves corresponding to the first heating unit is Y / 2=25, and 25 bits are taken from a preset 32-bit array. The 25 bits can represent the number of on-half waves from 1 to 25, and each bit represents whether the current half wave is on or off;

[0216] The complementary conduction can be that the sum of the number of bits of the two conducting half-waves is 25, for example, half-wave 1 and half-wave 24. The complementary conduction of half-wave 1 and half-wave 24 means that when half-wave 1 is on, half-wave 24 is off; when half-wave 1 is off, half-wave 24 is on. In the present application, when the positive half-wave or half-wave of the AC wave corresponding to the first heating unit is partially or fully conducted, the conducted half-waves can be evenly distributed in the AC wave corresponding to the first heating unit, so that after the first heating unit is conducted, the operating power of the first heating unit corresponding to the first heating unit is relatively stable and has less fluctuation.

[0217] Specifically, such as Figure 6 , which is an exemplary schematic diagram showing when the positive half-wave or half-wave of the AC wave corresponding to the first heating unit is partially or fully turned on, wherein 1 in the table indicates that half-wave is turned on, and a space indicates that half-wave is not turned on.

[0218] In a specific embodiment, the preset number is 50, and the AC waves corresponding to the first heating unit and the second heating unit are both 25. When the number of AC waves is 25, both the positive half-wave and the negative half-wave are 25 half-waves. Figures 7a-7d As shown, the AC wave corresponding to the first heating unit is represented by A, and the AC wave corresponding to the second heating unit is represented by B.

[0219] If the current conduction power ratio is 0-25%, the positive half-wave of the AC wave corresponding to the first heating unit is controlled to be fully or partially conducted;

[0220] For example, Figure 7a , which is a schematic diagram showing that the positive half-wave of the AC wave corresponding to the first heating unit is fully conducted when the current conduction power ratio is 25%.

[0221] If the current conduction power ratio is greater than 25% and less than or equal to 50%, the positive half-wave of the AC wave corresponding to the first heating unit is controlled to be fully or partially conducted; the negative half-wave of the AC wave corresponding to the second heating unit is controlled to be fully conducted;

[0222] For example, Figure 7b As shown, it is a schematic diagram of when the current conduction power ratio is 50%, the positive half-wave of the AC wave corresponding to the first heating unit is fully conducted, and the negative half-wave of the AC wave corresponding to the second heating unit is fully conducted;

[0223] If the current conduction power ratio is greater than 50% and less than or equal to 75%, the positive half-wave of the AC wave corresponding to the first heating unit is controlled to be fully or partially conducted, and the negative half-wave is controlled to be fully conducted; the negative half-wave of the AC wave corresponding to the second heating unit is controlled to be fully conducted;

[0224] For example, Figure 7cAs shown, it is a schematic diagram of when the current conduction power ratio is 75%, the positive half-wave and the negative half-wave of the AC wave corresponding to the first heating unit are all conducted, and the negative half-wave of the AC wave corresponding to the second heating unit is all conducted;

[0225] If the current conduction power ratio is greater than 75% and less than or equal to 100%, the positive half-wave of the AC wave corresponding to the first heating unit is controlled to be fully or partially conducted, and the negative half-wave is controlled to be fully conducted; the positive half-wave and negative half-wave of the AC wave corresponding to the second heating unit are controlled to be fully conducted;

[0226] For example, Figure 7d The figure shows a schematic diagram of a first heating unit and a second heating unit, with both the positive and negative half-waves of the AC wave corresponding to the first heating unit fully conducting when the current conduction power ratio is 100%. This application employs this conduction pattern, and ensures that during the conduction of the AC wave with the first and second heating units in this pattern, the maximum difference between two adjacent AC waves is one and a half waves. This results in relatively stable operating power for the electric heating device, with minimal power fluctuations.

[0227] In the embodiment of the present application, during the heating process of the first heating unit and the second heating unit, if the heating power reaches a constant, the first heating unit and the second heating unit can be controlled to operate in an alternating conduction manner when switching gears.

[0228] Specifically, it is possible to determine whether the heating power of the two heating units reaches a constant state by measuring the difference in the conduction power ratio between two adjacent cycles;

[0229] In the embodiments of this application, Figure 8 , which is a flow chart of a control method of a hair care device with constant heating power provided by an embodiment of the present application; the details are as follows:

[0230] S501: Calling a preset proportional-integral-derivative control algorithm to obtain a target on-power ratio for the next cycle.

[0231] In the embodiment of the present application, the next air outlet gear temperature calibration value and the next actual air outlet temperature of the next cycle can be used, and the temperature difference between the next air outlet gear temperature calibration value and the next actual air outlet temperature can be calculated and processed using a preset proportional integral differential control algorithm to obtain the target conduction power ratio;

[0232] Specifically, the method for calculating using the preset proportional-integral-differential control algorithm is the same as the method for calculating the current on-power ratio;

[0233] S503: Subtract the current conduction power ratio from the target conduction power ratio to obtain a first power ratio difference.

[0234] In the embodiment of the present application, after the target conduction power ratio of the next cycle is calculated, the target conduction power ratio is subtracted from the current conduction power ratio to obtain a first power ratio difference;

[0235] S505: If the first power ratio difference is less than or equal to the preset threshold, obtain a target half-wave conduction number corresponding to the target conduction power ratio.

[0236] In the embodiment of the present application, the preset threshold may be a ratio threshold; for example, it may be 25%;

[0237] If the first power ratio difference is less than or equal to a preset threshold, it can be determined that the heating power of the first heating unit and the second heating unit has reached a constant state;

[0238] At this time, the target half-wave conduction number corresponding to the target conduction power ratio can be calculated based on the target conduction power ratio and the preset number;

[0239] Specifically, the target half-wave conduction number corresponding to the target conduction power ratio can be obtained by multiplying the target conduction power ratio by twice the preset number.

[0240] S507: Determine a target conduction strategy according to the target half-wave conduction number, the preset number, and the current conduction strategy.

[0241] In the embodiment of the present application, the target conduction strategy may be a conduction mode of controlling the AC waves corresponding to the first heating unit and the second heating unit to conduct half-wave conduction;

[0242] Specifically, it may include a distribution method and a conduction method of half waves in a preset number of AC waves corresponding to the next cycle;

[0243] Specifically, the next conduction strategy for the next cycle may be determined based on the target half-wave conduction number and the preset number;

[0244] Based on the heating power of the first heating unit and the second heating unit reaching a constant state, in order to make the heating power of the first heating unit and the second heating unit consistent, when the AC wave is half-wave conducted according to the next conduction strategy, the conduction mode of the AC wave in the first signal sub-unit corresponding to the first heating unit and the conduction mode of the AC wave in the second signal sub-unit corresponding to the second heating unit are swapped when the AC wave is half-wave conducted according to the current conduction strategy;

[0245] Specifically, if the current conduction power ratio is equal to the target conduction power ratio of the next cycle, the conduction mode of the AC wave in the first signal sub-unit corresponding to the first heating unit at the current conduction power ratio is made corresponding to the conduction mode of the AC wave in the second signal sub-unit corresponding to the second heating unit at the target conduction power ratio;

[0246] The conduction mode of the AC wave in the second signal subunit corresponding to the second heating unit at the current conduction power ratio is made to correspond to the conduction mode of the AC wave in the first signal subunit corresponding to the first heating unit at the target conduction power ratio.

[0247] For example, Figure 9 As shown, if the current conduction power ratio and the target conduction power ratio of the next cycle are both 75%, the AC wave corresponding to the first heating unit is represented by A, and the AC wave corresponding to the second heating unit is represented by B.

[0248] like Figure 9 In the upper middle figure, in the current cycle, the positive and negative half-waves of the AC wave in the first signal sub-unit corresponding to the first heating unit are all conductive, and the positive half-wave of the AC wave in the second signal sub-unit corresponding to the second heating unit is all conductive, and the negative half-wave is not conductive;

[0249] like Figure 9 In the lower middle figure, in the next cycle, the positive half-wave of the AC wave in the first signal sub-unit corresponding to the first heating unit is fully conductive, and the negative half-wave is not conductive, and the positive and negative half-waves of the AC wave in the second signal sub-unit corresponding to the second heating unit are fully conductive.

[0250] S509: Perform half-wave conduction processing according to the target conduction strategy, so that the first heating unit and the second heating unit operate at a conduction power corresponding to the target conduction power ratio.

[0251] In another embodiment of the present application, if the first power ratio difference is greater than a preset threshold, the current conduction power ratio and a second preset ratio of the preset threshold are added together to determine the first conduction power ratio, so that the first heating unit and the second heating unit operate at a conduction power corresponding to the first conduction power ratio;

[0252] In the embodiment of the present application, if the first power ratio difference is greater than a preset threshold, it is necessary to use the current conduction power ratio as the base conduction power ratio, and perform conduction processing at least twice by increasing the base conduction power ratio so that the conduction power ratio reaches the target conduction power ratio;

[0253] Specifically, the second preset ratio may be 1 times, that is, 1 times the preset threshold;

[0254] The first power ratio difference being greater than the preset threshold value may be greater than 25%; in this case, the sum of the current conduction power ratio and 1 times the preset threshold value may be used as the first conduction power ratio;

[0255] If the preset threshold is 25%, then the first conduction power ratio = current conduction power ratio + 25%;

[0256] After obtaining the first conduction power ratio, the first conduction strategy of the next cycle can be determined according to the first conduction power ratio and the preset number;

[0257] Controlling the next cycle to perform half-wave conduction processing with the first conduction strategy, so that the first heating unit and the second heating unit operate at a conduction power corresponding to the first conduction power ratio;

[0259] If the second power ratio difference is less than or equal to the preset threshold, the AC wave corresponding to the next cycle is controlled to perform half-wave conduction processing with the first conduction power ratio + the second power ratio difference (target conduction power ratio), so that the first heating unit and the second heating unit operate at the conduction power corresponding to the target conduction power ratio;

[0260] In another embodiment of the present application, if the second power ratio difference is greater than a preset threshold, the first conduction power ratio and a second preset ratio of the preset threshold are added together to determine a second conduction power ratio, so that the first heating unit and the second heating unit operate at a conduction power corresponding to the second conduction power ratio;

[0261] In the embodiment of the present application, the second preset ratio may be 1 times, that is, 1 times the preset threshold;

[0265] Controlling the next cycle to perform half-wave conduction processing with a second conduction strategy, so that the first heating unit and the second heating unit operate at a conduction power corresponding to the first conduction power ratio;

[0266] Repeat the step of adding and calculating the first conduction power ratio and the second preset ratio of the preset threshold; until the target difference between the second conduction power ratio and the target conduction power ratio is less than or equal to the preset threshold, and execute the step of controlling the AC wave corresponding to the next cycle to perform half-wave conduction processing with the target conduction strategy, so that the first heating unit and the second heating unit operate with the conduction power corresponding to the target conduction power ratio.

This allows the AC power to be conducted with a small, steady increase in power ratio until the hair care device reaches a constant temperature, further improving the operating power stability of the first and second heating units.
