Description

Technical Field

[0001] This utility model relates to the field of hair styling tools, and in particular to a hair styling tool that can be used for both straightening and curling. Background Technology

[0002] In the hair styling tool industry, as consumers' demand for diverse hairstyles continues to increase, hair styling tools with multiple styling functions have become the focus of the market. Users want to quickly straighten their hair to create a smooth style, and also expect to easily create natural curls to suit the hairstyle needs of different occasions. However, existing hair styling tools are relatively simple in function, mostly only having the single function of straightening or curling hair, making it difficult to meet users' diverse styling needs for both straight and curly hair at the same time.

[0003] From a structural design perspective, traditional hair straighteners typically have a flat straightening plate structure. When the two plates are closed, they can only apply vertical pressure and heat to the hair. This structural design limits their application to straightening hair. Curling irons, on the other hand, use a curved barrel structure. Hair is wrapped around the barrel and heated to achieve curls. These two structures are independent and difficult to integrate into a single device. Integrating straightening and curling functions requires a completely new design that can apply vertical pressure to straighten hair while also using a special structure to curl and set the curl. However, a mature integrated structural design solution is currently lacking.

[0004] In terms of airflow design, existing hair styling tools are all designed around a single function. Hair straighteners, for straightening hair, blow hot air in a single direction, usually parallel to the straightener blades, aiming to quickly dry hair and assist in styling. Curling irons, on the other hand, focus on evenly circulating air around the hair to help quickly style curly hair. Because the two functions have significantly different requirements for airflow direction, speed, and temperature, existing hair styling tools cannot simultaneously meet the different needs of straightening and curling with a single airflow system. Therefore, developing an integrated hair styling tool that combines straightening and curling functions requires innovative improvements to the structural design and airflow system to fill a market gap and meet consumers' growing demand for multi-functional hair styling solutions.

Detailed Implementation

[0030] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] Please see Figure 1-6In this embodiment of the present invention, a hair straightener and curler includes a main body 10, which is a hollow structure. A control circuit 11 is integrated inside the main body 10. One end of the main body 10 has an air inlet 12, and the other end of the main body 10 is connected to a nozzle 20, forming a fluid channel inside the main body 10 from the air inlet 12 to the nozzle 20. A motor 14 and a heating unit 13, which are electrically connected to the control circuit 11, are disposed in the fluid channel. The fluid channel generates directional fluid through the motor 14, which enters along the air inlet 12, flows through the heating unit 13, and is blown out from the nozzle 20. The nozzle 20 includes an air outlet 30 and a baffle 40, wherein:

[0032] The air outlet 30 includes an outer ring 31 fixedly connected to the main body 10 and two hair clippers 32 formed on the outer ring 31. The two hair clippers 32 are hollow structures and are connected to the fluid channel through the outer ring 31. The two hair clippers 32 have straight hair surfaces 321 that are arranged opposite each other to clamp the hair and curly hair surfaces 322 that are arranged back to back to curl the hair. A straight hair air outlet 323 is provided on the straight hair surface 321. Directional fluid guides the hair between the two straight hair surfaces 321 and blows it out in the same direction through the straight hair air outlet 323. A curly hair air outlet 324 is provided on the curly hair surface 322. Directional fluid guides the hair to conform to the curly hair surface 322 and curl it through the curly hair air outlet 324.

[0033] The wind deflector 40 includes an inner ring body 41 rotatably connected to the inner side of the outer ring body 31 and two wind deflectors 42 formed on the inner ring body 41 and respectively extending into the two hair clippers 32. The wind deflectors 42 have a first blocking part 421a / 422a for blocking the straight hair air outlet 323 and a second blocking part 421b / 422b for blocking the curling hair air outlet 324.

[0034] A toggle member 50 is provided at the positions of the inner ring body 41 and the outer ring body 31 to drive the inner ring body 41 to rotate, so that the inner ring body 41 can rotate to two positions. When the inner ring body 41 rotates to one position, the first blocking part 421a / 422a blocks the straight air outlet 323, while the second blocking part 421b / 422b moves away from the coiled air outlet 324. When the inner ring body 41 rotates to the other position, the first blocking part 421a / 422a moves away from the straight air outlet 323, while the second blocking part 421b / 422b blocks the coiled air outlet 324.

[0035] When this hair straightener and curler is in operation, after the device is turned on, the control circuit 11 starts the motor 14 and the heating unit 13. The airflow generated by the motor 14 enters the fluid channel inside the main body 10 through the air inlet 12, flows through the heating unit 13 and is heated, forming directional hot air that is blown out from the nozzle 20. When straightening is needed, the inner ring 41 is rotated by the toggle 50, causing the first blocking part 421a / 422a to move away from the straightening air outlet 323, and the second blocking part 421b / 422b to block the curling air outlet 324. At this time, the hot air enters the hair-cutting body 32 through the outer ring 31 and is blown out from the straightening air outlet 323. The directional fluid guides the hair to be placed in two... The straight hair surfaces 321 of the hair clipper 32 blow air in the same direction. While the straight hair surfaces 321 restrict the hair, the hot air changes the keratin structure in the hair and rearranges the hydrogen bonds, thus achieving a straight hair effect. When curling is needed, the toggle 50 is moved again to rotate the inner ring 41 to another position, so that the first blocking part 421a / 422a blocks the straight hair air outlet 323, and the second blocking part 421b / 422b moves away from the curling air outlet 324. The hot air blows out through the curling air outlet 324, and the directional fluid guides the hair to adhere to the curling surface 322 and curl. The hot air heats and shapes the curled hair, creating a curly hairstyle.

[0036] This design breaks away from the limitations of traditional hair straighteners or curling irons, integrating straightening and curling functions into one unit. This satisfies diverse hair styling needs, eliminating the need for separate straightening and curling tools, saving costs and storage space. The ingenious structural design, with its rotatable wind deflector 40 and uniquely designed clipper body 32, allows for easy switching between straightening and curling functions with a simple toggle, simplifying operation and reducing user difficulty. From a user experience perspective, the optimized airflow design ensures that the hot air is applied more precisely to the hair, whether straightening or curling, improving styling efficiency.

[0037] Please see Figure 6 Based on the above technical solution, it is further proposed that the straightening surface 321 has a flat structure, and the straightening surfaces 321 of the two hair-cutting bodies 32 are spaced apart, forming a space between the two straightening surfaces 321 that allows hair to pass through, making it convenient for users to smoothly pass the hair through this space for straightening operations; the curling surface 322 has an arc-shaped structure, and the centers of the corresponding circles of the curling surfaces 322 of the two hair-cutting bodies 32 are on the same axis. Utilizing the Candareen effect, the hair is tightly wrapped and curled along the arc surface under the action of hot air, which helps to create a curling effect with uniform curvature and regular shape, improving the aesthetics and durability of the curls, and this structural design makes the curling process smoother.

[0038] Please see Figure 3-6Based on the above technical solution, it is further proposed that the straightening air outlet 323 be set in a long strip shape along the length of the straightening surface 321, and the straightening air outlet 323 is close to the same side of the two straightening surfaces 321, and faces the other side of the straightening surface 321 at an angle. This guides the hair to enter from one side of the straightening surface 321 and be blown out from the other side of the straightening surface 321, ensuring that the hair is heated evenly throughout the straightening process and effectively avoiding local overheating damage to the hair. At the same time, this angle setting can form an airflow thrust, guiding the hair to smoothly enter from one side of the straightening surface 321 and be blown out from the other side, improving the straightening efficiency and ease of operation.

[0039] One of the straightening surfaces 321 has an extended straightening air vent 323 with a first guide channel 33. The other straightening surface 321 has a straightening air vent 323 where a first blocking part 421a / 422a is exposed to the outside of the hair clipper body 32. The portion of the first blocking part 421a / 422a exposed to the outside of the hair clipper body 32 has a second guide channel 34 that connects to the inside of the hair clipper body 32. The first guide channel 33 and the second guide channel 34 are used to guide the directional fluid to flow out at an angle toward the other side of the straightening surface 321. The addition of the first guide channel 33 and the second guide channel 34 further enhances the guiding effect of the directional fluid, allowing the hot air to act on the hair at a more precise angle and direction, enhancing the wrapping and force of the hot air on the hair during straightening, making the hair fit the straightening surface 321 better, and improving the straightness and smoothness of the straightening effect.

[0040] Multiple evenly distributed first air guide plates 35 are provided in both the first guide channel 33 and the second guide channel 34, which can disperse the hot air into multiple fine and uniform airflows, avoiding the hot air from being too concentrated or disordered. This not only makes the hair more evenly and finely heated, but also reduces the impact of the wind on the hair, reducing the occurrence of frizz and flyaways, further optimizing the user experience during the straightening process, and achieving a more ideal and higher quality straightening styling effect.

[0041] Please see Figure 3-6Based on the above technical solution, it is further proposed that multiple evenly distributed curling air vents 324 are provided. These multiple curling air vents 324 are arranged in a long strip structure along the length of the curling surface 322, allowing hot air to evenly cover the curling area of ​​the hair, avoiding uneven heating in certain areas that could affect the curling effect. Furthermore, the curling air vents 324 are positioned at an angle tangent to the curling surface 322. Multi-lobed protrusions 36 corresponding to the multiple curling air vents 324 are formed on the outside of the curling surface 322. The curling air vents 324 are positioned at an angle tangent to the curling surface 322 through the protrusions 36. The angle of the curling surface 322, combined with the multi-lobed protrusions 36 on the outside of the curling surface 322, forms a unique airflow channel. This allows hot air to blow out along the tangential direction of the curling surface 322, conforming to the curling trajectory of the hair. The resulting airflow force guides the hair to adhere tightly to the curling surface 322, enhancing the shaping effect and three-dimensionality of the curls. Furthermore, the curling air outlet 324 extends along the inner part of the protrusions 36 and is equipped with a third guide channel 37. The third guide channel 37 guides the directional fluid to flow out at an angle tangential to the curling surface 322, allowing the hot air to act on the hair at a more precise angle, strengthening the curl styling effect. Multiple evenly distributed second air guide plates 38 are set in the third guide channel 37, dispersing the hot air into a fine and gentle airflow, reducing the impact of the hot air on the hair, preventing damage to the hair due to high temperature and strong wind, and promoting more even penetration of the hot air into the hair, making the curl style more refined and smooth, effectively improving the user's experience during the curling process and the final styling quality.

[0042] Please refer to the figure. Figure 1 and Figure 3 Based on the above technical solution, the actuating component 50 is further proposed to include an elongated hole 51 on the outer ring body 31 and an actuating part 52 formed on the inner ring body 41. The actuating part 52 extends out of the outer ring body 31 along the elongated hole 51 and can be moved back and forth along the elongated hole 51. The user can directly move the actuating part 52 extending out of the outer ring body 31 by hand, so as to make it move back and forth along the elongated hole 51, thus realizing the rotation of the inner ring body 41 in a simple and intuitive way, thereby quickly switching the opening and closing states of the straightening air outlet 323 and the curling air outlet 324, and completing the conversion between straightening and curling functions. This structural design is not only easy to operate and reduce the user's learning cost, but also the elongated hole 51 plays a limiting and guiding role in the movement of the actuating part 52, ensuring that the actuating part 52 moves stably during operation, avoiding deviation or jamming when the inner ring body 41 rotates, and ensuring the smoothness and reliability of the hair styling tool's function switching.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
