Abstract
Description
Technical Field
[0001] The present application relates to the technical field of hair straightening, and in particular to a multifunctional hair straightener and a control method thereof. Background Art
[0002] A hair straightener, also known as a hair straightener or electric curling iron, is a personal care appliance that uses heat to temporarily straighten and style hair. Its basic operating principle is that an internal heating element (such as a PTC or MCH heater) heats two plates (usually made of metal or ceramic). The user then slides their hair between the heated plates. The heat temporarily breaks the hydrogen and disulfide bonds in the hair, reshaping it and achieving a straight or curly effect.
[0003] Related art hair straighteners pose thermal and chemical damage to hair, causing irreversible damage due to high temperatures. Hair is primarily composed of keratin, which is highly sensitive to heat. When temperatures exceed its denaturation threshold (generally considered to be above 180°C-220°C), keratin permanently degrades, leaving hair dry, brittle, and prone to breakage. While existing products offer temperature adjustment, users often blindly use the highest setting to achieve quick styling results or to achieve desired results for stubborn hair, exacerbating the risk of hair damage. Alternatively, even if users prefer a lower setting, they may find that lower temperatures are insufficient for achieving the desired straightening or curling effects, forcing them to opt for a higher setting. Existing hair straighteners also pose safety risks: the working surface of the straightener can reach extremely high temperatures after use, posing a risk of burns to the scalp, ears, or neck. Furthermore, most existing hair straighteners lack adaptive intelligent adjustment features: the vast majority cannot automatically identify hair quality (e.g., fine, coarse, or damaged), hair thickness, or ambient humidity, requiring the user to manually select the temperature setting. Incorrect selection can lead to poor results or hair damage. The lack of dynamic power and temperature regulation based on real-time feedback (such as hair moisture content and speed) indicates a low level of intelligence. Consequently, hair straighteners in related technologies suffer from the drawbacks of high temperatures that can easily damage hair, the risk of burns from extremely high temperatures, and poor regulation.

[0030] The following is combined with Figure 1-5 This application is described in further detail.
[0031] Example 1: Reference Figure 1 and Figure 2A multifunctional hair straightener includes an aluminum alloy cavity, an outer shell and an air inlet base. Hot air enters the aluminum alloy cavity and is blown out from the side of the aluminum alloy cavity. A cooling air duct is formed between the aluminum alloy cavity and the outer shell. When the hot air is blown out, it drives natural wind to pass through the cooling air duct quickly, thereby reducing the temperature of the outer shell.
[0032] Reference Figure 3 The outer shell includes an upper shell 9 and a lower shell 10. The air inlet base is provided with a first air inlet 17, and hot air enters the aluminum alloy cavity from the first air inlet 17 at the rear end of the outer shell. The aluminum alloy cavity includes an upper cavity 1 and a lower cavity 2; the upper cavity 1 is provided with a first heating plate 3, and the lower cavity 2 is provided with a second heating plate 4, which are used to conduct heating temperature; a first air duct 5 is formed in the upper cavity 1, and a second air duct 6 is formed in the lower cavity 2; the hot air entering the first air inlet 17 is diverted to the first heating plate 3 and the second heating plate 4 through the first air duct 5 and the second air duct 6. The first heating plate 3 and the second heating plate 4 are both configured as aluminum alloy heating plates, which can quickly conduct heat when the hot air passes through. The hot air of the multifunctional hair straightener first enters the aluminum alloy cavity through the first air inlet 17, quickly raising the surface temperature of the aluminum alloy, and the first heating plate 3 and the second heating plate 4 achieve a perming effect. A first air outlet 7 is provided on the side wall of one side of the upper cavity 1, and a second air outlet 8 is provided on the side wall of the same side of the lower cavity 2. In the embodiment of the present application, the first air outlet 7 and the second air outlet 8 are both provided on the left side of the hair straightener. The hot air entering the aluminum alloy cavity is blown out along the first air outlet 7 and the second air outlet 8 on the side of the aluminum alloy cavity, and cooperates with the aluminum alloy first heating plate 3 and the second heating plate 4 to achieve the effect of straightening hair.
[0033] A second air inlet 11 and a third air outlet 12 are formed between the upper shell 9 and the lower shell 10. The third air outlet 12 is located on the side with the first and second air outlets 7 and 8, while the second air inlet 11 is located on the side without the first and second air outlets 7 and 8, i.e., on the right side of the hair straightener. The upper shell 9 has a first opening 13 at the third air outlet 12, and the lower shell 10 has a second opening 14 at the third air outlet 12. The first and second openings 13 and 14 are used to increase the airflow. The cooling air duct includes a third air duct 15 and a fourth air duct 16. The third air duct 15 is formed between the upper shell 9 and the upper cavity 1, and the fourth air duct 16 is formed between the lower shell 10 and the lower cavity 2. Hot air enters the aluminum alloy cavity and is blown out through the first and second air outlets 7 and 8. Natural air enters through the second air inlet 11, passes through the third air duct 15 or the fourth air duct 16, respectively, to reduce the outer shell temperature, and is blown out through the third air outlet 12. The multifunctional hair straightener of the present application is affected by the change in air outlet pressure. According to the Bernoulli principle, natural wind is sucked in from the second air inlet 11 and flows to the third air outlet 12. The third air outlet 12 has a low pressure due to the rapid flow of hot air from the first air outlet 7 and the second air outlet 8. A room wind flow is naturally formed between the aluminum alloy cavity and the outer shell, which can increase the air outlet pressure and air volume of the third air outlet 12.
[0034] Because room-temperature air flows inside the housing, the present invention can keep the housing temperature close to room temperature. On the one hand, the housing temperature is relatively low, preventing burns. On the other hand, when the multifunctional hair straightener of the present invention is used for curling, the housing can cool the heated hair, improving the styling effect.
[0035] A push handle 18 is provided at the rear end of the housing. The push handle 18 is fixedly connected to the upper housing 9. A rotating shaft 22 is provided inside the housing, and the push handle 18 can rotate along the rotating shaft 22. When the push handle 18 is pressed, the first heating plate 3 and the second heating plate 4 are closed; when the push handle 18 is lifted, the first heating plate 3 and the second heating plate 4 are opened, and an angle is formed between the first heating plate 3 and the second heating plate 4; the push handle 18 is provided with a magnet mounting groove, the magnet mounting groove opening is backward, and a magnet block 21 is fixedly installed in the magnet mounting groove. As the push handle 18 rotates, when the push handle 18 is pressed, the magnet block 21 and the air inlet base are separated; when the push handle 18 is lifted, the magnet block 21 and the air inlet base are moved closer; a magnetic induction sensor is embedded in the air inlet base to detect changes in environmental magnetic force. The first and second heating plates 3 and 4 are closed, and the magnet block 21 separates from the air inlet base. The magnet block 21 follows the upper housing 9 away from the magnetic induction sensor. When the magnetic force sensed by the magnetic induction sensor falls below the set value Y, the first air inlet 17 begins to blow air according to the set value. Lifting and pressing the handle 18 opens the first and second heating plates 3 and 4, forming an angle between them. The magnet block 21 follows the upper housing 9 toward the magnetic induction sensor until it contacts the magnetic induction sensor. When the magnetic force sensed by the magnetic induction sensor exceeds the set value X, the hair straightener enters standby mode, shuts off the heating wire, and the first air inlet 17 enters standby mode, reducing the wind speed to a breeze. In this embodiment, the magnetic induction sensor is configured as a linear Hall effect sensor. As the magnetic force decreases, the hair straightener power increases. As the magnetic force increases, the hair straightener power decreases, and the hair straightener enters standby mode. However, the present application does not limit the method for configuring the magnetic force change, nor does the control logic for controlling the hair straightener. The linear Hall effect sensor detects the magnetic force by changing the opening angle of the movement, which serves as a trigger to control the hair straightener. When the hair straightener is opened to form an angle or closed, the magnet block 21 rotates simultaneously. The distance between the magnet block 21 and the magnetic induction sensor is detected and judged by the magnetic induction sensor to change the control logic of blowing or heating. The multifunctional hair straightener of the present application adopts a large curved appearance, which better achieves the curvature of the hair.
[0036] A silicone connector 23 is provided inside the housing. The front end of the silicone connector 23 is fixedly connected to the aluminum alloy upper cavity 1, and the rear end is connected to the fixed slot of the air inlet base. The silicone connector 23 ensures that the first air duct 5 and the second air duct 6 are still sealed and smooth when the hair straightener is in motion. Figure 4, a storage lock switch is provided below the silicone connector 23, and the lock switch includes a sliding piece 26, a switch button 28 and a limit protrusion 30. The switch button 28 is fixedly provided below the sliding piece 26, and the limit protrusion 30 is provided above the sliding piece 26. A slide groove 25 is formed between the outer wall of the air inlet base and the inner wall of the lower shell 10 for the movement of the sliding piece 26; Figure 5 The lower shell 10 is provided with a switch slot 27, and the switch button 28 can move back and forth within the switch slot 27; a spring 31 is also provided inside the shell, and a limit slot 29 is provided at the base of the air inlet, which cooperates with the limit protrusion 30. When the lock switch moves forward, the limit slot 29 engages with the limit protrusion 30, the switch is locked, and the spring 31 is compressed. The hair straightener is closed. When the lock switch moves backward, the limit slot 29 separates from the limit protrusion 30. When the switch is unlocked, the hair straightener remains in the open state under the action of the spring 31. Two silicone spring pads 32 are respectively provided in the third air duct 15 between the upper shell 9 and the upper cavity 1, and the fourth air duct 16 between the lower shell 10 and the lower cavity 2, for a total of four silicone spring pads 32. The silicone spring pads 32 provide a certain elastic space when the hair straightener is closed to prevent excessive force from clamping the hair. The front ends of the upper and lower housings 9 and 10 are respectively equipped with a first assembly cover 33 and a second assembly cover 34. The first assembly cover 33 secures and seals the first and second heating plates 3 and 4, while the second assembly cover 34 provides guidance. Furthermore, the guiding and burn-proof design of the second assembly cover 34 on the front end of the hair straightener ensures smooth insertion of the hair straightener.
[0037] A handle is fixedly provided on one side of the first air inlet, and the handle is connected to the rear end of the shell. A heating part and a blowing part are provided in the handle. The heating part is used to adjust the heating power and temperature of the hot air, and the blowing part is used to adjust the blowing power and speed. In the embodiment of the present application, the heating part is set as a heating wire, and the blowing part is set as a hair dryer.
[0038] Example 2: A control method, characterized in that the method comprises: Obtaining an execution command of the current hair straightener, wherein the execution command includes at least a hair straightening instruction and a hair curling instruction; When the execution command is a hair straightening instruction: the first heating plate 3 and the second heating plate 4 are turned on, an angle is formed between the first heating plate 3 and the second heating plate 4, the current opening angle of the hair straightener is obtained, and the heating power of the heating part is adjusted according to the opening angle and the wind speed level; When the execution command is a curling instruction: the first heating plate 3 and the second heating plate 4 are turned on, an angle is formed between the first heating plate 3 and the second heating plate 4, the current opening angle of the hair straightener is obtained, and the blowing power of the blowing part is adjusted according to the temperature level and the opening angle.
[0039] Furthermore, according to the selected execution command, when the execution command is a straight hair instruction: turn on the setting of the heating power; when the execution command is a curling hair instruction: turn on the setting of the blow-drying power.
[0040] Furthermore, the wind speed levels include a first wind speed F1, a second wind speed F2, and a third wind speed F3. When the command obtained is the first wind speed F1, the heating power can be adjusted to the first temperature range; when the command obtained is the second wind speed F2, the heating power can be adjusted to the second temperature range; and when the command obtained is the third wind speed F3, the heating power can be adjusted to the third temperature range. For example, if the first wind speed F1 is set to be less than the second wind speed F2, and the second wind speed F2 is set to be less than the third wind speed F3, the heating power in the first temperature range, the second temperature range, and the third temperature range will change from low to high, respectively. When the first wind speed F1 and the low heating power in the first temperature range are selected, low blowing power and low heating power are obtained. When the third wind speed F3 and the low heating power in the third temperature range are selected, high blowing power and low heating power are obtained. When the first wind speed F1 and the high heating power in the first temperature range are selected, low blowing power and high heating power are obtained. When the third wind speed F3 and the high heating power in the third temperature range are selected, high blowing power and high heating power are obtained. Similarly, you can get different modes of blowing power and heating power. In this mode, the blowing power adjustment range is three values, and the heating power adjustment range corresponds to three intervals.
[0041] The temperature levels include a first temperature F5, a second temperature F6, and a third temperature F7. When the command obtained is the first temperature F5, the blowing power can be adjusted to the first wind speed range; when the command obtained is the second temperature F6, the blowing power can be adjusted to the second wind speed range; when the command obtained is the third temperature F6, the blowing power can be adjusted to the third wind speed range. Similarly, for example, if the first temperature F5 is set lower than the second temperature F6, and the second temperature F6 is set lower than the third temperature F7, the blowing power in the first wind speed range, the second wind speed range, and the third wind speed range will change from low to high, respectively. Different modes of heating power and blowing power can be obtained. In this method, the heating power adjustment range is three values, and the blowing power adjustment range corresponds to three intervals.
[0042] The working principle of this control method is as follows: Generally, the greater the blowing power, the faster the wind speed of the first and second air ducts 5 and 6, as well as the wind speed of the third and fourth air ducts 15 and 16, and the faster the shell cools down. The higher the heating power, the higher the hot air temperature, the higher the temperature of the first heating plate 3 and the second heating plate 4, and the greater the impact on the shell.
[0043] When the blowing power is high and the heating power is low, the multifunctional hair straightener is in a rare quick cooling mode; when the blowing power is high and the heating power is high, the multifunctional hair straightener is in the curling mode; when the blowing power is low and the heating power is high, the multifunctional hair straightener is in the straightening mode; when the blowing power is low and the heating power is low, the multifunctional hair straightener is in the hair styling mode.
[0044] In summary, the present application provides a method for achieving anti-scalding and rapid styling effects by utilizing the hot air heating principle and the Bernoulli principle to achieve cooling. When the user operates the hair straightener, the first heating plate 3 and the second heating plate 4 are opened or closed, and the magnet block 21 will follow the hair straightener in conjunction with the magnetic induction sensor to sense the size and change of the magnetic force, and dynamically adjust the air intake volume and heating temperature of the first air inlet 17.
[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
