For the sake of understanding, the function of the smart curler will be introduced in the following with the smart curler workflow. Referring to FIG. 3, the working steps of the smart curler may include:

301. An infrared light emitting device in a smart curler emits an infrared light signal;

When the smart curling device is activated to perform the curling operation, the infrared light emitting device in the smart curling device emits an infrared light signal. Specifically, the infrared light signal may be a signal in the form of infrared light, and the wavelength thereof is between 760 nanometers (nm) and 1 mm. The infrared light signal may also be a signal in the form of an infrared laser, which is not limited herein.

302. The infrared light signal is received by the infrared light receiving device after passing through the curling shaft of the smart curler;

The infrared light emitting device emits the infrared light signal through the curling shaft of the smart curler, and the curling through shaft can heat and shape the hair wrapped thereon, and the infrared light in the infrared light receiving device when the curling shaft does not have the winding hair The intensity of the infrared light signal received by the receiving tube does not change. When the hair is wrapped around the hair shaft, the hair will block part of the infrared light signal, resulting in the intensity of the infrared light signal received by the infrared light receiving device changing. The infrared light signal also changes with the user's curling operation during the signal acquisition period, and the change of the infrared light signal can reflect the operation speed and the thickness of the curl during the curling operation.

Optionally, in the infrared light receiving device of the embodiment, at least one infrared receiving tube is disposed, and the infrared receiving tube is disposed at different height regions for receiving infrared light signals of different heights.

Preferably, three infrared receiving tubes can be disposed in the infrared light receiving device in the embodiment, and the three infrared receiving tubes are disposed in different height regions for receiving infrared light signals of different heights.

303. The intelligent curling device performs signal processing on the received infrared light signal to obtain an effective electrical signal;

The infrared receiving tube in the infrared light receiving device can convert the received infrared light signal into an electrical signal. For example, the infrared receiving tube converts the infrared light signal into a voltage signal, and the infrared light signal received by the infrared receiving tube is weaker, corresponding to The stronger the output voltage signal, the specific conversion circuit is the prior art, and will not be described here.

Further, the infrared light emitting device may set the signal processing circuit to perform signal amplification, wave-taking, compensation, correction, etc. on the electrical signals acquired in each signal acquisition period to finally obtain an effective electrical signal corresponding to each signal acquisition period, specifically The implementation of the signal processing circuit is not limited herein.

304, calculating the sum Va of the electrical signals corresponding to the infrared light signals collected at different heights in the same signal acquisition period;

For ease of understanding, in the embodiment, three infrared receiving tubes are disposed in the infrared light receiving device, and the infrared receiving tube converts the infrared light signals into voltage signals as an example. As shown in FIG. 4, the three infrared receiving tubes are disposed in different manners. The height area is used for receiving infrared light signals of different heights. When the infrared light signal received by the infrared receiving tube is weaker, the corresponding output voltage signal is stronger.

The three infrared receiving tubes in this embodiment output the voltage signal V3 in the infrared receiving tube 1043 arranged outside the curling pass according to different height regions of a certain distance, and the output voltage of the infrared receiving tube 1042 arranged on the inner side of the circular transmitting shaft is output. The signal V2 and the inner infrared receiving tube 1041 output a voltage signal V1, and V1, V2, and V3 vary in magnitude depending on the amount of hair. For example, in the first stage, when the amount of curl is gradually increased, the V1 signal value is saturated. V2 and V3 change according to the amount of hair. In the second stage, the V1 and V2 signal values will be saturated, and V3 will vary according to the amount of hair. Three infrared receiving tubes can be set to identify a wider range of hair volume and accurately detect. The effect of the thickness of the hair, the multiple rows of the infrared receiving tube is not limited to the above description, and the number can be increased or decreased or the arrangement can be changed. For example, two infrared receiving tubes can be arranged in different height regions, or in the same height region. A plurality of infrared receiving tubes are provided, which are not limited herein.

When the amount of hair is increased, the infrared light signal is blocked by the hair, the infrared receiving tube signal is weakened, the output voltage signal is raised, and the amount of hair placed corresponds to the voltage signal value corresponding to the output of the infrared receiving tube, which can be collected in the same signal acquisition period. The sum of the electrical signals corresponding to the infrared light signals of different heights reflects the current amount of hair placement, ie, V1+V2+V3=Va

305, determining a stable value Vn according to the Va value corresponding to different signal acquisition periods;

The hair is wound on the top of the curling shaft in a circle. When the first circle is taken, the Va1 value is calculated from the above. When the second coil is used, the value of Va2 is obtained. When the third circle is taken, the value of Va3 is obtained. The longer the number of turns wound on the roll pass, the more the Va value does not increase after the last roll of a bundle of hair is obtained to obtain the final stable value Vn, and the electrical signals corresponding to the infrared light signals of different heights that continue to be collected subsequently continue. And almost no change, in view of this, the stable value Vn and the time point corresponding to the stable value can be determined according to the Va value corresponding to different signal acquisition periods.

306. Match the curl value H corresponding to the stable value Vn according to a preset rule;

The sum of the electrical signals corresponding to the infrared light signals of different heights is in one-to-one correspondence with the thickness value H of the curl wound on the curling shaft, and the smart curler can store the correspondence between the two, when the smart curler obtains After the stable value Vn, it can be matched to the corresponding curl thickness value H.

307, calculating the length L of the curl according to the stability value Vn and the circumference C of the curling axis;

The circumference of the curling shaft is inherently set to C, and the length of the hair wound on the curling axis can be calculated according to the formula: L≈C*Vn.

308. Calculate the theoretical output temperature of the smart curler according to the curl value H and the curl length L, and adjust the actual output temperature of the smart curler to reduce the difference between the actual output temperature and the theoretical output temperature;

Specifically, the theoretical output temperature t of the smart curling iron can be according to the formula: t=H*L*M, where H is the curl thickness value, L is the curl length value, M is the preset temperature compensation constant, and the smart curler can adjust the actual The temperature is output to reduce the difference between the actual output temperature and the theoretical output temperature.

It can be understood that the calculation method of the theoretical output temperature shown in the refinement step of controlling the operating parameters of the smart hair curler according to the effective electric signal is merely exemplary. In actual operation, the user can reasonably change the above according to the demand.

The smart curler can determine the theoretical output temperature according to the effective electrical signal and adjust the actual output temperature parameter to reduce the actual output temperature and the theoretical output. The difference in temperature reduces the effect of manual differences on hairdressing.

309, according to the time point of the sum of the electrical signals corresponding to the infrared light signals of different heights reaching the stable value Vn and the initial time point of the curling operation, calculating the curling process time T used for the curling operation;

The smart curling device can obtain the curling process time T used for the curling operation by subtracting the initial time point of the curling operation from the sum of the electrical signals corresponding to the infrared light signals of different heights to reach the stable value Vn.

310. Calculate the theoretical curl setting time Ts according to the curling process time T, the curl thickness value H and the curl length L;

Specifically, the theoretical curl setting time Ts can be calculated according to the formula Ts=H*L*P+T, where H is the curl thickness value, L is the curl length value, P is the preset time compensation constant, and T is the curling process time.

311. Starting at the initial time point of the curling operation, after the timing time reaches the theoretical curl setting time Ts, the smart curler performs a preset prompting process to prompt the user that the curling shaping has been completed.

The timing starts at the initial time of the curling operation. After the timing time reaches the theoretical curling setting time Ts, the smart curler performs a preset prompting process to prompt the user that the curling has been completed.

It can be understood that the calculation method of the theoretical curl setting time shown in the refinement step of controlling the operating parameters of the smart curler according to the effective electrical signal is merely exemplary. In actual use, the user can change reasonably according to the demand. The above calculation steps are used to calculate a reasonable theoretical hair curling setting time, and the specific calculation method is not limited herein.

In this embodiment, when the smart curling device is activated to perform the curling operation, the infrared light emitting device in the smart curling device emits an infrared light signal, and the infrared light signal changes in the hair occlusion through the curling shaft of the smart curling device, and the smart The curling iron can perform signal processing on the received infrared light signal to obtain an effective electrical signal, and the intelligent curling device can determine the theoretical curl setting time according to the effective electrical signal, start timing at the initial time of the curling operation, and reach the theory at the time of counting. After the curling setting time Ts, the smart curler performs a preset prompting process to prompt the user that the curling shape has been completed, and reduces the influence of the manual operation difference on the hairdressing effect.

It can be understood that, in the embodiment of the present invention, the smart curling device can individually control its actual output temperature parameter or timing parameter according to the effective electrical signal, and can also realize the actual input at the same time. The control of the temperature parameter or the timing parameter is not limited herein.

It is to be understood that the size of the sequence of the above-mentioned steps does not imply a sequence of executions, and the order of execution of the steps should be determined by its function and internal logic, and should not be construed as limiting the implementation of the embodiments of the present invention.

The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to be limiting; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that The technical solutions described in the embodiments are modified, or the equivalents of the technical features are replaced by the equivalents of the technical solutions of the embodiments of the present invention.
