Description

Technical Field

[0001] The present invention relates to the technical field of hair styling devices, in particular to a hair styling device for both straightening and curling hair. Background Art

[0002] In the field of hair styling tools, as consumers' demand for more diverse hairstyles continues to rise, hair styling tools with multiple styling functions have become a market focus. Users want to be able to quickly straighten their hair for a smooth look, while also expecting to easily create natural curls to suit different hairstyles. However, existing hair styling tools are relatively limited in functionality, with most offering only a single function for straightening or curling hair, making it difficult to simultaneously meet users' diverse styling needs for both straightening and curling hair. From a structural design perspective, traditional hair straighteners typically have flat plates that, when closed, only apply vertical pressure and heat to the hair. This design makes them suitable only for straightening hair. Curling irons, on the other hand, use a curved barrel structure, where hair is wrapped around the barrel and heated to create a curling effect. These two independent structures make it difficult to integrate these functions into the same device. Integrating these two functions requires a novel structure that applies vertical pressure to the hair for straightening while also providing a special structure for curling and shaping the hair. However, a mature integrated structural design currently lacks a proven solution.

[0003] In terms of airflow design, the airflow designs of existing hairdressers are all centered around a single function. A hair straightener used for straight hair has a single direction of hot air blown out by its nozzle, usually parallel to the straightening plate, designed to quickly dry the hair and assist in styling straight hair; whereas the airflow design of a curling iron focuses on evenly surrounding the hair, helping to quickly style curly hair. Due to the significant differences in the two functions' requirements for airflow direction, wind speed, and temperature, it is difficult for existing hairdressers to simultaneously meet the different needs of straightening and curling hair with a single airflow system. Therefore, the development of an integrated hairdresser with both straightening and curling functions requires innovative improvements to the structural design and airflow system to fill the market gap and meet consumers' growing demand for multi-functional hairdressing.

DETAILED DESCRIPTION

[0019] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-6 In an embodiment of the present invention, a hair straightener and curling device includes a main body 10. The main body 10 is a hollow structure. A control circuit 11 is integrated in the main body 10. An air inlet 12 is provided at one end of the main body 10. A nozzle 20 is connected to the other end of the main body 10. A fluid channel is formed inside the main body 10 along the air inlet 12 to the nozzle 20. A motor 12 and a heating unit 13, each electrically connected to the control circuit 11, are provided in the fluid channel. The fluid channel generates a directional fluid through the motor 12, 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 wind shield 40, wherein: The air outlet member 30 includes an outer ring body 31 fixedly connected to the main body 10 and two hair-cutting bodies 32 formed on the outer ring body 31. The two hair-cutting bodies 32 are hollow structures and communicate with the fluid channel through the outer ring body 31. The two hair-cutting bodies 32 have straight hair-cutting surfaces 321 arranged opposite to each other for clamping hair and curling hair-cutting surfaces 322 arranged opposite to each other for curling hair. The straight hair-cutting surfaces 321 are provided with straight air outlets 323, through which directional fluid is directed to guide hair between the two straight hair-cutting surfaces 321 and blown out in the same direction. The curling hair-cutting surfaces 322 are provided with curling air outlets 324, through which directional fluid is directed to guide hair to curl along the curling hair-cutting surfaces 322. The windshield 40 includes an inner ring 41 rotatably connected to the inner side of the outer ring 31 and two windshields 42 formed on the inner ring 41 and extending into the interiors of the two haircutting bodies 32, respectively. The windshield 42 has a first blocking portion 421a / 422a for blocking the straight air outlet 323 and a second blocking portion 421b / 422b for blocking the curling air outlet 324. A toggle member 50 is provided at the position of the inner ring body 41 and the outer ring body 31 for driving the inner ring body 41 to rotate, so that the inner ring body 41 can rotate into two positions. When the inner ring body 41 rotates to one of the positions, the first blocking portion 421a / 422a blocks the straight air outlet 323, and the second blocking portion 421b / 422b moves away from the curling air outlet 324; when the inner ring body 41 rotates to the other position, the first blocking portion 421a / 422a moves away from the straight air outlet 323, and the second blocking portion 421b / 422b blocks the curling air outlet 324.

[0021] When the hair straightening and curling dual-purpose hair styling device is in operation, after the device is turned on, the control circuit 11 starts the motor 12 and the heating unit 13. The airflow generated by the motor 12 enters the fluid channel in the main body 10 from the air inlet 12, flows through the heating unit 13 and is heated, and then forms a directional hot air that is blown out from the air nozzle 20. When straight hair is needed, the inner ring body 41 is rotated by the toggle member 50, so that the first blocking part 421a / 422a is moved away from the straightening air outlet 323, and the second blocking part 421b / 422b blocks the curling air outlet 324. At this time, the hot air enters the hair cutting body 32 through the outer ring body 31 and is blown out from the straightening air outlet 323. The directional fluid guides the hair to be placed on the two The hot air is blown in the same direction between the straightening surfaces 321 of the hair cutting body 32. The straightening surfaces 321 not only restrict the hair but also cooperate with the hot air to change the keratin structure in the hair and rearrange the hydrogen bonds, thereby achieving a straightening effect. When curling the hair, the toggle member 50 is toggled again, and the inner ring body 41 is rotated to another position, so that the first blocking portion 421a / 422a blocks the straightening air outlet 323, and the second blocking portion 421b / 422b moves away from the curling air outlet 324. The hot air is blown out through the curling air outlet 324, and the directional fluid guides the hair to curl around the curling surface 322. The hot air heats and shapes the curled hair to create a curly style.

[0022] This arrangement breaks the functional limitation of traditional hair straighteners or curling irons with a single function, integrates the straightening and curling functions into one, and meets the diverse hairdressing needs of users. Users do not need to purchase straightening and curling tools separately, saving costs and storage space. The structural design is ingenious. Through the rotatable wind shield 40 and the uniquely designed hair cutting body 32, a simple toggle operation can achieve switching between straightening and curling functions, which is convenient to operate and reduces the difficulty of use for users. From the user experience point of view, the reasonable airflow design ensures that whether it is straightening or curling, the hot air can act on the hair more accurately, thereby improving hairdressing efficiency.

[0023] See also Figure 6 Based on the above technical solution, the hair straightening surface 321 is further proposed to be flat, and the straightening surfaces 321 of the two hair cutting bodies 32 are spaced apart, creating a space between the two straightening surfaces 321 for hair to pass through, facilitating the user to smoothly pass hair through the space for hair straightening. The hair curling surface 322 is an arc-shaped surface, with the centers of the corresponding circles of the curling surfaces 322 of the two hair cutting bodies 32 coaxial. This utilizes the Candal effect, causing hair to curl tightly along the arc surface under the action of hot air, helping to create uniform and well-shaped curls, improving the beauty and durability of the curls. This structural design also makes the curling process smoother.

[0024] See also Figure 3-6 Based on the above technical solution, it is further proposed that the straightening air outlets 323 are arranged in a long strip structure along the length direction of the straightening surface 321, and the straightening air outlets 323 are close to the same side of the two straightening surfaces 321 and are angled toward the other side of the straightening surface 321, thereby guiding the hair to enter along 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, effectively avoiding local overheating and damage to the hair. At the same time, this angle setting can generate airflow thrust, guiding the hair to smoothly enter from one side of the straightening surface 321 and be blown out from the other side, thereby improving the efficiency of straightening and the convenience of operation.

[0025] The straightening air outlet 323 of one straightening surface 321 is extended to include a first guide channel 33. The straightening air outlet 323 of the other straightening surface 321 allows the first blocking portion 421a / 422a to be exposed outside the hair cutting body 32. The portion of the first blocking portion 421a / 422a exposed outside the hair cutting body 32 is provided with a second guide channel 34 that communicates with the interior of the hair cutting body 32. The first and second guide channels 33, 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 and second guide channels 33, 34 further enhances the directional fluid guidance effect, allowing the hot air to act on the hair at a more precise angle and direction. This enhances the wrapping and force of the hot air on the hair during straightening, allowing the hair to fit more closely to the straightening surface 321, and improving the straightness and smoothness of the straightening effect.

[0026] The first guide channel 33 and the second guide channel 34 are both provided with a plurality of evenly distributed first air guide plates 35, which can disperse the hot air into multiple small and even air flows, and avoid the hot air from being too concentrated or disordered. This not only makes the hair heated more evenly and delicately, but also reduces the impact of wind on the hair, and reduces the occurrence of frizzy and flying hair, further optimizing the user experience during the straightening process, and achieving a more ideal and higher-quality straightening effect.

[0027] See also Figure 3-6 On the basis of the above technical solution, it is further proposed that a plurality of evenly distributed curling air outlets 324 are provided. The plurality of curling air outlets 324 are arranged in a long strip structure along the length direction of the curling surface 322, so that hot air can evenly cover the curling part of the hair, avoiding uneven heating in some parts that affects the curling effect, and the curling air outlets 324 are arranged at an angle tangent to the curling surface 322; a multi-petal protrusion 36 corresponding to the plurality of curling air outlets 324 is formed on the outside of the curling surface 322, and the curling air outlets 324 are arranged at an angle tangent to the curling surface 322 through the protrusion 36. The angled design tangential to the curling surface 322, combined with the multi-lobed raised portion 36 on the outer surface of the curling surface 322, creates a unique airflow path. This directs hot air outward along the curling surface 322, conforming to the hair's curling trajectory. The resulting airflow force guides the hair tightly against the curling surface 322, enhancing the curling effect and three-dimensionality. Furthermore, a third guide channel 37 is provided within the raised portion 36, extending from the curling outlet 324. This third guide channel 37 guides the directional fluid outflow at an angle tangential to the curling surface 322, allowing the hot air to strike the hair with a more precise angle and enhancing the curling effect. Multiple evenly distributed second air guide plates 38 are positioned within the third guide channel 37, dispersing the hot air into a delicate and gentle airflow, reducing the impact of the hot air on the hair and preventing damage from high temperatures and strong winds. This also ensures that the hot air penetrates the hair more evenly, resulting in a more refined and smooth curling experience, effectively improving the user's curling experience and the final styling quality.

The cam 56 is actuated by a spring 56 which is adapted to move the cam 56 back and forth along the slot 51 so that the cam 56 can be rotated relative to the cam 56.
