Description

CROSS REFERENCE TO RELATED APPLICATION

The present application claims the priority to Chinese patent application No. 202011473736.2, titled “HAIR CURLING METHOD AND HAIR CURLER”, filed with the China National Intellectual Property Administration on Dec. 15, 2020, which is incorporated herein by reference in its entirety.

FIELD

The present application relates to the technical field of hair curling tools, and in particular to a hair curling method and a hair curler.

BACKGROUND

With the progress of society, the standard of beauty is gradually diversified, and people's pursuit of beauty has not only been limited to clothing but gradually expanded to various aspects, such as cosmetology, makeup and hair styling. Based on this, a hair curling iron is one of the indispensable tools configured to realize hair styling.
The hair curling irons on the market at present are mainly classified into manual hair curling irons and semi-automatic hair curling irons. Since the manual hair curling irons relatively test skill proficiency and easily cause scald, and require better skills, the semi-automatic hair curling irons gradually become the first choice of tools for non-professionals. For example, the patent with the present application number CN201520739411.2 discloses a hair styling tool, which includes a handle. The handle is provided with a rotating shaft that can rotate relative to the handle, and two parallel heating elements are formed on an end of the rotating shaft. The heating elements extend along the axial direction of the rotating shaft, and a gap for clamping hair is formed between the two heating elements. A circuit board and a motor are arranged in the handle, and a control key is arranged on the handle, where the motor is configured to drive the rotating shaft to rotate. The heating elements, the control key and the motor are respectively electrically connected to the circuit board, where the circuit board is configured to control the heating of the heating elements, and to control the motor to rotate forward or reversely according to an electrical signal input by the control key, so as to cause the two heating elements to rotate forward or reversely by a preset angle.
Although the above hair styling tool controls the rotation angle of heating elements to prevent hair from being tangled and stuck, this kind of situation is still unavoidable in actual operation. In a case that the hair is tangled to cause the hair curling iron to be stuck, adverse consequences, such as pulling of the scalp, and burning of the hair, easily occur to a user under a rush, so that the safety is poor.

DETAILED DESCRIPTION OF THE EMBODIMENTS

For making the objects, features and advantages of the present application clearer and easier to be understood, the technical solutions in the embodiments of the present application are described clearly and completely hereinafter in conjunction with the drawings in the embodiments of the present application. Apparently, the embodiments described hereinafter are only a part of the embodiments of the present application, rather than all embodiments. Any other embodiments obtained by those skilled in the art based on the embodiments in the present application without any creative effort shall fall within the protection scope of the present application.
Technical solutions of the present application will be illustrated in detail through the embodiments and in conjunction with the drawings.
A hair curling method is provided according to embodiments of the present application, and the hair curling method is realized based on an automatic hair curling iron.
For ease of understanding, an automatic hair curling iron in the prior art is provided here, which includes a first handle, a second handle and a heating plate that are strip-shaped as a whole. A first end of the first handle is hinged to a first end of the second handle, and a hair curler is arranged at a side of a second end of the first handle facing the second handle. The hair curler includes a hair curling column facing the second handle and vertically arranged on the first handle; and a hair pushing portion which is connected with an electric device and rotatable around the hair curling column. A protection wall is arranged on the outer periphery of the hair pushing portion, a first groove is defined on the protection wall, and the bottom of the first groove is lower than the top of the hair pushing portion. The heating plate includes a first heating plate arranged on the outer periphery of the bottom of the hair curling column, and a second heating plate arranged on the second end of the second handle, opposite to the first heating plate. Based on the above structure, the hair is placed in the first groove, and the electric device is controlled to drive the hair pushing portion to rotate around the hair curling column, so as to curl the hair around the hair curling column. After that, the first handle and the second handle are combined, and the first heating plate and the second heating plate are controlled to heat the hair wound around the hair curling column, thereby forming an S-shaped three-dimensional hairstyle.
It can be understood that, this automatic hair curling iron may be any kind of automatic hair curling irons on the market, and is not limited to the automatic hair curling iron of the aforementioned type, which does not constitute a limitation to the embodiments of the present application. The automatic hair curler to which the hair curling method provided by the embodiments of the present application can be applied generally includes at least a hair curling member configured to be driven to rotate to curl the hair. The hair curling member rotates by a certain angle, by a certain number of revolutions and by certain strength, and the hair curling member is positioned after rotating by a designated number of revolutions. At the same time, the hair is heated and styled at a certain temperature, so as to curl the hair.
Referring to FIG. 1, the hair curling method provided according to the embodiments of the present application includes the following steps S1 to S8.
In step S1, an operation instruction is obtained.
Specifically, the operation instruction can be obtained by reading a key value of a start button when the user presses the start button. Alternatively, a placement state of the hair on the hair curling member can be detected. When the hair is placed in position, an operation instruction is automatically generated, so that the operation instruction can be obtained.
In this step, the operation instruction may include hair curling modes selected by a user according to styling needs, and the hair curling modes include hair curling parameters, styling durations and styling temperatures of the hair curling member.
Specifically, the curling parameters may further include curling directions of the hair and the numbers of revolutions of curling. It can be understood that the hair curling parameters can be preset by the user, and specifically can be set according to lengths of the hair, styling needs and the diameter of the hair curling member.
In step S2, the operation instruction is executed to curl hair.
The operation instruction is used to control the hair curling member to rotate in a designated direction by a second designated number of revolutions, where the second designated number of revolutions is the above number of revolutions of curling.
The designated direction includes the clockwise or counterclockwise rotation direction. Further, the situation that the hair curling member rotates counterclockwise or clockwise further includes a situation that the rotation axis of the hair curling member is perpendicular to the hair and a situation that an included angle between the rotation axis of the hair curling member and the hair is less than 90 degrees.
In step S3, whether the hair is tangled or not is determined in a process of executing the operation instruction; if the hair is tangled, executing step S4; and if the hair is not tangled, executing step S8.
In this step, in a case that the number of revolutions of rotation is less than the second designated number of revolutions, a driving member for driving the rotation of the hair curling member stops rotating, and the hair is determined as being tangled. It can be understood that a tension force on the hair during the curling process can also be detected as a basis for determining whether the hair is tangled. When the tension force exceeds a certain threshold, the hair can be determined as being tangled.
In step S4, the hair curling member is controlled to stop.
By controlling the hair curling member to stop, the hair is prevented from being further tangled in time, and a tangling degree of the hair is prevented from being further improved.
In step S5, the hair curling member is controlled to rotate in a direction opposite to the designated direction.
When the hair curling member rotates in the direction opposite to the designated direction, the number of revolutions of rotation is a first designated number of revolutions. The first designated number of revolutions is set, so that the tangle state of the hair is lifted after the hair curling member has rotated the first designated number of revolutions.
In the actual use process, when the hair is tangled during the curling process, it is generally possible to release the tangle state by reversing half a revolution. Therefore, in one of implementation manners of the present embodiment, the first designated number of revolutions is half a revolution or at least half a revolution, most degree of the tangle situations can be lifted with this arrangement.
Referring to FIG. 2, in another implementation manner of the present embodiment, the first designated number of revolutions may also be adaptively determined according to the degree of tangling of the hair, which is specifically as follows.
When the hair is tangled, before controlling the hair curling member to rotate in the direction opposite to the designated direction, the following steps S501 and S502 are also included.
In step S501, a tangle parameter of the hair is detected.
In step S502, the tangle parameter is analyzed and calculated to obtain the first designated number of revolutions.
The tangle parameter of the hair may be the thickness, the length of and even the number of revolutions of a tangled part. For example, when the hair is initially curled, the thickness of a bundle of curled hairs can be measured first, and based on this, the first designated number of revolutions is calculated. In a case that the tangle parameter is length, calculation is executed according to the diameter of the hair curling member, the current number of revolutions of curling when the tangle occurs, or the curling thickness of the hair. It can be understood that the tangle parameter may also be other parameters, which are not limited hereto.
By executing steps S501 and S502, the number of revolutions of reverse rotation of the hair curling member is adaptively provided according to the degree of tangling of the hair, so as to avoid secondary tangling of the hair caused by excessive reversing in a case that the tangle state of the hair is ensured to be lifted.
In yet another implementation manner of the present embodiment, before executing step S5, that is, before the hair curling member is controlled to rotate in a direction opposite to the designated direction, the following steps are also included.
The current number of revolutions of hair curling is recorded, and the current number of revolutions of hair curling is set as the first designated number of revolutions.
Based on this, after executing step S5, that is, after the hair curling member is controlled to rotate in a direction opposite to the designated direction, that is, after the hair curling member has rotated by the first designated number of revolutions in this direction, the hair curling member can return to the starting point before the hair is tangled, thereby accurately releasing the tangle state of the hair.
Further, in step S5, after controlling the hair curling member to rotate in the direction opposite to the designated direction, the following steps are included.
In step S6, whether the tangle state of the hair is lifted or not is determined. If the tangle state of the hair is lifted, step S7 is executed, and if the tangle state of the hair is not lifted, the process returns to step S5.
When the tangle state of the hair is not lifted, the process returns to step S5 again, and the hair curling member is controlled to rotate along the direction opposite to the designated direction. In this process, the first designated number of revolutions can be re-determined by executing steps S501 and S502 to further fine-tune the number of revolutions of reverse rotation of the hair curling member, thereby further improving the accuracy of the operation of lifting the tangle state of the hair.
In step S7, the automatic hair curling iron is controlled to shut down.
When the tangle state of the hair is lifted, a shutdown operation is executed. At this time, since the hair has been lifted from the tangle state, the user can smoothly take out the hair from the automatic hair curling iron under the shutdown state while saving the operation of manually lifting the tangle state, thereby further improving the operation convenience of the automatic hair curling iron.
In step S8, when the hair curling member has rotated by the second designated number of revolutions, a heating operation is executed, and the process returns to step S1.
If the automatic hair curling iron is not tangled in the hair curling process, and has smoothly rotated by the second designated number of revolutions corresponding to the operation instruction, the hair curling operation is further executed with the parameters such the styling duration and the styling temperature in the operation instruction, so as to curl and style the hair.
Referring to FIG. 3, based on the above embodiments, a hair curler is further provided according to the present application, where the hair curler includes an obtaining module 10, an execution module 20, a 30 detection module, and an analysis and calculation module 40.

The execution module 20 is configured to execute the operation instruction to control the hair curling member to rotate in the designated direction by the second designated number of revolutions.
The designated direction includes the clockwise or counterclockwise rotation direction. Further, the situation that the hair curling member rotates counterclockwise or clockwise further includes a situation that the rotation axis of the hair curling member is perpendicular to the hair and a situation that an included angle between the rotation axis of the hair curling member and the hair is less than 90 degrees.
The execution module is further configured to, when the hair is tangled, control the hair curling member to stop and control the hair curling member to rotate by a first designated number of revolutions in a direction opposite to the designated direction.
By controlling the hair curling member to stop, the hair is prevented from being further tangled in time, and a tangling degree of the hair is prevented from being further improved.
The execution module is further configured to, when the tangle state of the hair is lifted, control the automatic hair curling iron to shut down.
When the tangle state of the hair is lifted, a shutdown operation is executed. At this time, since the hair has been lifted from the tangle state, the user can smoothly take out the hair from the automatic hair curling iron under the shutdown state while saving the operation of manually lifting the tangle state, thereby further improving the operation convenience of the automatic hair curling iron.
The execution module is further configured to, when the hair curling member has rotated by the second designated number of revolutions, execute a heating operation.
If the automatic hair curling iron is not tangled in the hair curling process, and has smoothly rotated by the second designated number of revolutions corresponding to the operation instruction, the hair curling operation is further executed with the parameters such the styling duration and the styling temperature in the operation instruction, so as to curl and style the hair.
The 30 detection module is configured to:

- determine whether the hair is tangled or not in a process of executing the operation instruction.

Specifically, in a case that the number of revolutions of rotation is less than the second designated number of revolutions, a driving member for driving the rotation of the hair curling member stops rotating, and the hair is determined as being tangled. It can be understood that a tension force on the hair during the curling process can also be detected as a basis for determining whether the hair is tangled. When the tension force exceeds a certain threshold, the hair can be determined as being tangled.
The detection module 30 is further configured to, when the hair is tangled, detect a tangle parameter of the hair.
Specifically, the tangle parameter includes a thickness parameter and a parameter of the number of revolutions.
The detection module 30 is further configured to determine whether the tangle state of the hair is lifted or not.
In the same way, whether the tangle state of the hair is lifted or not can be determined by the above tangle parameter.
The analysis and calculation module 40 is configured to analyze and calculate the tangle parameter to obtain the first designated number of revolutions, or record the current number of revolutions of hair curling when the tangle occurs, so as to determine the first designated number of revolutions.
Specifically, the analysis and calculation module 40 calculates the number of revolutions of reverse rotation of the hair curling member according to the degree of tangling of the hair, so as to adaptively provide the number of revolutions of reverse rotation of the hair curling member, thereby avoiding secondary tangling of the hair caused by excessive reversing in a case that the tangle state of the hair is ensured to be lifted.
