Description

Technical Field

[0001] This application relates to the field of hair styling devices, and more particularly to a hair styling device and method based on synchronous shaping and setting by temperature difference. Background Technology

[0002] Hair straighteners, as common hair styling tools, work on the principle of breaking hydrogen bonds in the hair through heating, followed by physical straightening and cooling to set the style, thus achieving a straight hair effect. Traditional hair straighteners typically use a double-sided heating plate structure, heating both sides simultaneously when clamping the hair, raising the hair temperature and opening the hydrogen bonds. Subsequently, natural cooling in the air allows the hydrogen bonds to recombine, completing the styling process.

[0003] However, traditional hair straighteners have the following obvious drawbacks: 1. Low shaping efficiency: After heating, the tool needs to be removed and the material needs to be cooled naturally by the environment. The whole process takes a long time and cannot achieve continuous and rapid shaping.

[0004] 2. Unstable styling effect: The natural cooling process is affected by ambient temperature, humidity and external forces, which can easily cause hair to bounce back and deform, resulting in poor styling durability.

[0005] 3. High risk of heat damage: In pursuit of quick styling, users often tend to use higher temperatures, which can easily lead to heat damage such as dry hair, split ends, and breakage if exposed to high temperatures for a long time.

[0006] 4. Limited applicable hair types: High-temperature operation can easily cause irreversible damage to heat-sensitive hair (such as damaged hair, fine and soft hair) or synthetic fiber wigs.

[0007] 5. Poor operational continuity: Heating and cooling are separated, requiring multiple clamping or waiting times, which affects the user experience and shaping efficiency.

[0008] Currently, although some products on the market have attempted to introduce temperature control or short-term cooling functions into the hair straightener, most of them still rely on symmetrical heating or only provide passive heat dissipation. They cannot simultaneously complete heating and shaping and active cooling and setting in a single clamping session. Therefore, there is still considerable room for improvement in terms of efficiency, effectiveness, and hair care. Summary of the Invention

[0009] The technical problem this application aims to solve is the shortcomings of traditional hair straighteners, such as low styling efficiency, unstable styling effect, high risk of heat damage, limited applicable hair types, and poor operational consistency. To address these shortcomings of existing technologies, this application provides a hair styling tool and method based on simultaneous temperature difference shaping and setting.

[0010] To solve the above-mentioned technical problems, the technical solution adopted in this application is: A hair styling tool based on synchronous shaping and setting based on temperature difference is constructed, including an upper handle, a lower handle, and a pivot connecting the two. The front ends of the upper and lower handles form a clamping area for accommodating hair. The tool is characterized by further including a first clamping component and a second clamping component. The first clamping component is disposed at the end of the upper handle near the clamping area and has a first clamping surface facing the clamping area. The second clamping component is disposed at the end of the lower handle near the clamping area and has a second clamping surface facing the clamping area and opposite to the first clamping surface. When the upper and lower handles are closed to clamp the hair, the first and second clamping surfaces respectively contact both sides of the hair, creating a temperature difference within the clamping area.

[0011] Preferably, the first clamping assembly includes a heating unit for heating the first clamping surface, and the second clamping assembly includes a cooling unit for cooling the second clamping surface.

[0012] Preferably, the heating unit includes a first temperature-changing plate and a control plate electrically connected thereto, and the cooling unit includes a second temperature-changing plate. The heating temperature range of the first clamping surface is 120°C to 230°C, and the cooling temperature range of the second clamping surface is 10°C to 50°C.

[0013] Preferably, the first clamping assembly further includes a first bracket and a carbon plate disposed between the first bracket and the first temperature-changing plate, and the second clamping assembly includes a second aluminum frame, a heat sink frame, and a plug that fixes the two together.

[0014] Preferably, the cooling unit further includes a heat sink and a fan. The second variable temperature plate is disposed between the second aluminum frame and the heat sink. The heat sink is provided with heat dissipation fins, and the gaps between them form an air flow channel. The fan is disposed on the heat sink and is used to drive air to flow through the flow channel to perform forced air cooling on the second variable temperature plate.

[0015] Preferably, the second temperature plate is a semiconductor cooling chip, with its cold end attached to the second aluminum frame and its hot end attached to the heat sink.

[0016] A hair styling method based on the aforementioned temperature-difference synchronous shaping and setting hair styling device is characterized by comprising the following steps: S1: Activate the hair straightener and set a predetermined temperature difference between the first clamping surface and the second clamping surface; S2: Place a section of hair to be styled into the opened clamping area; S3: Close the upper handle and the lower handle so that the first clamping surface and the second clamping surface are respectively in close contact with both sides of the hair; S4: While maintaining the clamped state, perform a styling operation on the hair; During the styling process, the side of the hair that contacts the first clamping surface is simultaneously heated to achieve shaping, while the side of the hair that contacts the second clamping surface is simultaneously and actively cooled to achieve setting.

[0017] Preferably, the styling operation includes: maintaining the clamped state for a predetermined time to achieve a curly hairstyle.

[0018] Preferably, the styling operation includes: sliding the hair straightener along the hair length direction to achieve a straight hair style.

[0019] Preferably, in step S1, the temperature of the first clamping surface is set to 140°C to 160°C, and the temperature of the second clamping surface is set to 10°C to 30°C.

[0020] The hair styling tool and method based on synchronous shaping and setting of hair by temperature difference provided in this application form an asymmetrical temperature zone structure by setting a heating component on one side and a cooling component on the other side. It can simultaneously achieve hair heating and shaping and active cooling and setting in a single clamping, and has the following significant beneficial effects: 1. Efficient shaping, saving time: Heating and cooling are carried out simultaneously, and shaping and setting can be completed in a single clamping, which greatly shortens the overall shaping time and improves the continuity and efficiency of operation.

[0021] 2. Stable and long-lasting hold: The active cooling system quickly lowers the hair temperature, causing the hydrogen bonds to rapidly recombine and "freeze" while the hair is straightened, significantly reducing hair bounce and making the styling effect more lasting and stable.

[0022] 3. Reduces heat damage and provides better hair care: Due to timely cooling, the same styling effect can be achieved at a relatively low temperature or in a shorter heating time, reducing the duration of hair exposure to high temperatures and heat accumulation damage, making it more suitable for all hair types, especially damaged hair.

[0023] 4. Wide range of applications: The rapid cooling mechanism is especially suitable for heat-sensitive hair or synthetic fiber materials, expanding the applicable scenarios and people for hair straighteners.

[0024] 5. Easy to operate and excellent user experience: No need to switch tools or wait for cooling down, straightening and shaping can be completed with a single swipe, lowering the barrier to entry and enhancing the styling experience.

[0025] 6. Scientific shaping for superior results: By guiding water molecules to migrate directionally between the hot and cold zones through dual-temperature zones, hydrogen bond recombination becomes more regular, resulting in a more uniform and straight shaping effect, such as... Figure 11 and Figure 12The test results shown indicate that the hair straightener of this application has a significantly better straightening effect than the traditional symmetrical heating type hair straightener in the same amount of time.

[0026] In summary, this application not only achieves simultaneous integration of heating and cooling in terms of technology, but also makes substantial improvements in user experience, styling effect and hair care, and has strong practicality and market promotion value.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this application. Obviously, the described embodiments are some embodiments of this application, but not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0029] This application presents a preferred embodiment of a hair styling tool and method based on synchronous shaping and setting due to temperature difference; the hair styling tool is mainly a straightener for straightening or curling hair, and this application specifically describes a straightener. Figures 1-3 As shown, it includes an upper handle 10 and a lower handle 11. The upper and lower handles are connected by a pivot 13, allowing them to rotate. The tail ends of the upper and lower handles are connected by a tail sleeve 12. A push button 50 is provided on the tail sleeve, and a locking key 51 is provided inside the tail sleeve corresponding to the push button. Pushing the push button can cause the locking key to move toward or away from the upper handle, thereby changing the maximum clamping angle of the upper and lower handles. A clamping area 20 is formed between the other ends of the upper handle 10 and the lower handle 11. A first clamping component 70 is provided on the upper handle near the clamping area, and a second clamping component 80 is provided on the lower handle near the clamping area. A control board 40 is also provided inside the lower handle. A power cord 60 is connected to the end of the tail sleeve. The power cord supplies power to the control board to enable the hair straightener to operate. At the same time, multiple sets of switches 30 are provided on the lower handle corresponding to the control board. The multiple sets of switches include a power switch and a gear adjustment switch. The power switch turns the hair straightener on or off, and the gear adjustment switch can control the heating temperature of the hair straightener. Light guide columns can be provided on the upper handle and the lower handle. Different colors of light are emitted by the light guide columns to determine the working status of the hair straightener. When the hair straightener is in operation, set the temperature of the first clamping component and the second clamping component as needed, place the hair in the clamping area 20, and then press the upper handle 10 and the lower handle 11 to make the upper handle and the lower handle move relative to each other to change the size of the clamping area until the first clamping component 70 and the second clamping component 80 contact the hair and clamp the hair. Then pull the hair straightener along the hair length direction to make the hair straightener move along the hair length direction to straighten the hair.

[0030] Specifically, such as Figures 3-4As shown, the upper handle 10 is provided with a locking groove 16, and the locking key 51 is provided with a locking part 52 corresponding to the locking groove. A through hole 15 is provided in the middle of the tail sleeve. The push button 50 passes through the through hole and connects to the locking key 51. The push button can move back and forth within the through hole to drive the locking key, thereby changing the length of the locking part 52 entering the locking groove. It should be noted that when the locking part is placed in the locking groove, the maximum opening angle of the upper and lower handles is limited due to the blocking effect of the locking key. This can be set as the initial opening angle. To facilitate adjustment of the initial opening angle, the locking part is designed as a slope. Different lengths of the locking part entering the locking groove can change the initial opening angle of the upper and lower handles, making adjustment more convenient. A spring 14 is also provided between the upper handle 10 and the lower handle 11. The spring is compressed when the hair straightener is clamping the hair, and when the clamping is released, the spring returns to its original position, pushing the upper and lower handles back to the initial opening angle. Furthermore, the initial opening angle setting facilitates faster operation time during subsequent hair clamping, allowing the upper and lower handles to adjust their opening angles from the initial angle to 0 more quickly and easily. Both the upper handle 10 and the lower handle 11 include a housing and an internal mounting structure for accommodating and securing the first clamping assembly 70, the second clamping assembly 80, the control board 40, and related wiring. Their specific shape and internal layout can be designed according to ergonomic and assembly requirements, representing conventional techniques in this field. The power cord 60 is connected via the tail sleeve 12 and electrically connected to the control board 40 to provide power.

[0031] Furthermore, such as Figures 5-6As shown, the first clamping assembly 70 includes a first bracket 700 and a first aluminum frame 706 disposed at the lower end of the first bracket. The lower end surface of the first aluminum frame is the first clamping surface 7061 that contacts the hair. A first temperature-regulating plate 704 is disposed between the first aluminum frame and the first bracket, and a carbon plate 705 is disposed between the first temperature-regulating plate and the first aluminum frame. The first temperature-regulating plate is connected to the control board and can generate heat, transferring the heat through the carbon plate to the first aluminum frame, and then to the first clamping surface that contacts the hair. First latches 709 are provided at both ends of the first bracket 700, allowing for a detachable connection between the first clamping assembly and the upper handle, facilitating the disassembly and installation of the first clamping assembly. Locking blocks are provided on the left and right sides of the first bracket 700, and corresponding hooks are provided on the first aluminum frame. The hooks pass through the locking blocks and contact the elastic ends on both sides of the fuse spring 702, connecting the first aluminum frame and the first bracket. Both the locking blocks and the hooks are designed with oblique contact surfaces, facilitating the insertion of the hooks into the gap between the two sets of locking blocks and locking them into the top of the locking blocks. A fuse 701 is installed on the fuse spring 702 to provide protection for the first clamping assembly and prevent overheating. An NTC aluminum sheet 703 is also installed to monitor the heating temperature of the first temperature-changing plate and transmit the detected temperature to the control board for convenient temperature monitoring. The fuse spring secures the first temperature-changing plate between the first bracket and the first aluminum frame to prevent movement and poor contact. To improve heat transfer to the first clamping surface, the first aluminum frame 706 has multiple sets of circular holes to enhance thermal conductivity; however, these holes may not be included.

[0032] Furthermore, such as Figures 7-10 As shown, the second clamping assembly 80 includes a second aluminum frame 800 and a heat sink 804. The upper surface of the second aluminum frame is a second clamping surface 807 that contacts the hair, and a second temperature-changing plate 808 is placed between the heat sink and the second aluminum frame. The two ends of the second aluminum frame and the heat sink are connected and fixed by plugs 801, and the plugs are provided with second latches 809. The second clamping assembly can be detachably connected to the lower handle through the second latches, which facilitates the disassembly and installation of the second clamping assembly. A thermistor 810 can be installed on the heat sink to monitor the temperature of the second temperature-changing plate, thereby determining the temperature of the first clamping surface. A recessed portion 811 is provided in the middle of the heat sink 804, and a fan 803 is installed in the recessed portion. An air inlet 805 is provided at the lower end of the plug. A flow channel 806 is formed between the heat dissipation fins on the heat sink. When the fan 803 operates, external air enters through the air inlet 805, flows through the flow channel 806 of the heat sink 804, carries away the heat dissipated by the second temperature plate 808 through the heat sink 804, and is finally exhausted by the fan 803. This achieves forced air cooling to reduce the temperature of the second temperature plate 808 and the second clamping surface 807. This results in a difference in the heat generated by the first and second temperature plates, thus creating two different temperatures on the first and second clamping surfaces.

[0033] As a preferred embodiment, the second temperature plate 808 can be a TEC (thermoelectric cooling) plate, with its cold end attached to the second aluminum frame 800 and its hot end attached to the heat sink 804. After being powered on, it can form a cooling surface on the second clamping surface 807, while the first clamping surface 7061 is a heating surface. The direct heating and cooling surfaces are combined for better direct heating effect.

[0034] By setting the first clamping component 70 and the second clamping component 80 to different temperatures, the temperatures of the first clamping surface and the second clamping surface differ. This achieves the superposition of two important elements in hair styling: "heat" and new "water molecule movement," resulting in faster hair styling and less hair damage. By setting different temperature ranges for the first and second clamping surfaces—the first clamping surface being set to a high-reaction temperature range, such as 140-160℃, and the second clamping surface being set to a setting temperature range, such as 10-30℃—traditional hair straighteners use the same temperature for both clamping surfaces, breaking down water molecules with heat and then recombining them after cooling. In this application, due to the temperature difference of 110-150℃ between the first and second clamping surfaces, this temperature difference induces water molecule transfer. Figure 11 As shown, a hair straightening test was conducted on a traditional hair straightener and the hair straightener of this application. Real hair was placed inside each set of straighteners, and the hair was straightened within 15 seconds. The difference in straightening effect was observed. The test environment was a room temperature of 24±1℃ and a humidity of 45±5%. The straightening temperature of the traditional hair straightener was 140℃, while the temperature of the first clamping surface of this application was 140℃ and the temperature of the second clamping surface was 50℃. Clearly, the hair straightening effect of this application is better. Figure 12 As shown, traditional hair straighteners straighten hair by reshaping hydrogen bonds (water molecule bonds). Initially, the hydrogen bonds (water molecules) in frizzy hair follow a certain pattern, but this pattern causes the hair to bend and become frizzy. During heating, the hydrogen bonds break, straightening the hair. When the hair cools, the hydrogen bonds recombine, fixing the style. However, because the two clamping surfaces of a traditional straightener are at the same temperature, the water molecules move randomly, resulting in an uneven distribution of water molecules during styling and a poor styling effect. This application, however, uses a second clamping surface as a cooling surface, allowing water molecules to transfer from the hot zone to the cold zone during straightening. The movement of hydrogen bonds is more regular, achieving a better straightening effect. Furthermore, the presence of the cooling surface also strengthens the styling, reduces straightening time, and improves straightening efficiency.

[0035] The hair straightener of this application clamps hair via a relatively rotatable upper handle 10 and lower handle 11. A first clamping component 70 is located inside the upper handle, and a second clamping component 80 is located on the lower handle. The first clamping component is a heating component used to heat and shape the hair, while the second clamping component is a cooling component used to actively cool the hair after it has been heated and shaped, allowing for rapid styling. Because the first and second clamping surfaces are positioned opposite each other when closed, in a single clamping operation, one side of the hair contacts the first clamping surface of the first clamping component and is heated and shaped, while the other side contacts the second clamping surface of the second clamping component and is rapidly cooled and shaped. This allows shaping and styling to be completed almost simultaneously in a single clamping operation, resulting in high efficiency and time savings. Simultaneously, the active and rapid cooling provided by the cooling plate of the second clamping component immediately "freezes" the hydrogen bond structure after shaping, greatly reducing springback and resulting in a more lasting and stable hairstyle. Furthermore, due to the rapid cooling, the temperature required for shaping may be lowered (or the time required at the same temperature is shortened), reducing the total time the hair is exposed to high temperatures and minimizing heat damage. No need to switch tools or wait for natural cooling; the clamping process completes both steps in one operation, making it more convenient. Rapid cooling is especially beneficial for heat-sensitive hair or synthetic fibers, making it suitable for all hair types. This significantly reduces the total time required for hair styling (shaping + setting), improves hold, reduces hair bounce, makes hairstyles last longer, and reduces the risk of heat damage caused by prolonged exposure to high or excessively high temperatures.

[0036] The heating plate system of the first clamping assembly 70 of this application can be made of aluminum alloy or ceramic-coated metal as the heating plate substrate. The heating element can be made of MCH, aluminum sheet + spring sheet, etc., and the temperature sensor is an NTC thermistor. The operating temperature range of the temperature control circuit is 120-230℃, and the temperature control method includes constant temperature or multi-level adjustment. The cooling plate system of the second clamping assembly 80 can be cooled by a TEC plate, i.e., the cold end faces the hair and the hot end faces the inside of the device. The heat sink is equipped with multiple sets of fins, and the cooling fan is forced air cooling. Its temperature range is the temperature that the surface of the cooling plate can reach, such as dropping to 10℃-25℃ or lower, depending on the power and ambient temperature. When starting the hair straightening process, the user turns on the power and sets the heating temperature and cooling intensity. The heating plates heat up to the set temperature, and the cooling system also starts working (it may be running at low power while the plates are open in standby mode, or it may activate upon detecting clamping action). When a section of hair is placed into the open plates, the upper and lower handles are closed, clamping the hair between the first clamping surface of the heating plate and the second cooling surface of the cooling plate. In the closed state, the side of the hair closest to the first clamping surface is heated, breaking hydrogen bonds and straightening (or curling) the hair. Simultaneously, the side of the hair closest to the second clamping surface is actively cooled, rapidly lowering the hair temperature and causing the hydrogen bonds to recombine and "freeze" in a new state, completing the styling. After sliding the plates (for straight hair) or holding them for a period of time (for curly hair), the user opens the plates. The hair has been styled and set, and the next section of hair can be processed immediately.

[0037] The styling method based on the above hair styling tool specifically includes the following steps: Step 1: Equipment Preparation and Parameter Setting Turn on the power switch and set the desired operating mode and temperature parameters using the gear adjustment switch. Specifically, the temperature of the first clamping surface 7061 is set to the high-temperature range required for heating and shaping, such as 140℃–160℃, via the control board 40; simultaneously, the temperature of the second clamping surface 807 is set to the low-temperature range for cooling and shaping, such as 10℃–30℃. At this time, the heating unit (such as the first temperature-changing plate 704) begins to heat up, and the cooling unit (such as the second temperature-changing plate 808 in conjunction with the fan 803) begins to operate, creating a stable and significant temperature difference (e.g., 110℃–150℃) between the first and second clamping surfaces. The light guide on the equipment can display the current operating status, such as heating ready, cooling operation, etc.

[0038] Step 2: Hair insertion and clamping Take a section of hair to be styled and place it into the clamping area 20 while the stylist is in the open position. The operator holds the upper handle 10 and the lower handle 11, applying pressure to rotate the hair around the pivot 13 until the first clamping surface 7061 and the second clamping surface 807 clamp the hair. During this process, the spring 14 is compressed, and the locking key 51 and the locking groove (16) can cooperate to limit the maximum opening angle, facilitating quick and consistent clamping of the hair.

[0039] Step 3: Simultaneous shaping and setting operations While maintaining the clamped state, perform the shaping operation. This operation is divided into two typical methods depending on the shaping goal: For straight hair styling: After clamping the hair, the operator smoothly slides the styler along the hair length. During the sliding process, the side of the hair in contact with the first clamping surface 7061 is continuously heated, causing hydrogen bonds to break and making the hair fibers smooth and malleable; simultaneously, the side of the hair in contact with the second clamping surface 807 is continuously and actively cooled. Due to the significant temperature difference between the two sides, water molecules migrate directionally from the high-temperature side to the low-temperature side under thermodynamic drive, and hydrogen bonds rapidly recombine and "freeze" on the cooling side, thus instantly setting the hair in a straightened state. This process simultaneously completes heating and shaping and cooling and setting in one slide.

[0040] For styling curly hair: After clamping the hair, the operator holds the styling tool in the current position for a period of time (e.g., several seconds to tens of seconds), or performs small rotations and wrapping motions. During this holding period, the part of the hair in contact with the high-temperature side is also heated and shaped, while the part in contact with the low-temperature side cools and sets simultaneously. The temperature difference causes water molecules to migrate in a directional manner, allowing the hydrogen bonds in the hair to quickly and orderly recombine on the cooling side to achieve the desired curl or bend, thus achieving the shaping and immediate setting of the curl.

[0041] Step 4: Completion and Subsequent Operations After styling, release the grip on the handles. Spring 14 will return the upper and lower handles to their initial opening angles, separating the styler from the hair. The hair is now shaped and set, and the next section can be styled immediately without waiting for it to cool naturally.

[0042] The core of this method lies in utilizing the stable temperature difference established and maintained between the first and second clamping surfaces to achieve temporal synchronization and spatial coupling of heating and shaping and active cooling for styling the same area of ​​hair in a single clamping operation. In traditional methods, heating and cooling are separated in time, and cooling is a passive, natural process. This method, however, establishes a cold zone on the second clamping surface using an active cooling unit (such as forced air cooling or semiconductor cooling), creating a gradient with the hot zone on the first clamping surface. This temperature difference not only accelerates heat removal from the hair but, more importantly, creates a driving force for the directional migration of water molecules (hydrogen-bonded water) from the hot zone to the cold zone. This directional migration makes the hydrogen bonds more ordered during cooling and recombination, thus significantly improving the styling speed, the durability and uniformity of the styling effect (e.g., ...). Figure 11 , Figure 12 (As shown). At the same time, due to timely cooling, the temperature required for shaping can be effectively reduced or the high-temperature action time can be shortened, thereby reducing the risk of heat damage to the hair.
