Description

TECHNICAL FIELD

[0001] The present invention relates to beauty aids and related technologies. More specifically, the present invention relates to a hair straightener with an automatic heat protection spray system that automatically adjusts the temperature depending on the hair type. BACKGROUND

[0002] Human hair is 90% keratin, a fibrous protein. Hair growth begins on the scalp, the skin tissue that covers the top of the head. Human hair plays an important role in protecting the skin, regulating body temperature, and much more. The part of the hair that the invention focuses on is the hair strands. Human hair is made up of three layers: medulla, cortex, and cuticle. The cuticle is the outermost layer of the hair strand, while the hair follicle is shaped like a tube that holds each individual hair in place. The medulla is the inner layer of the hair and is found primarily in thicker, curly hair, while it is absent or present in smaller quantities in finer hair.

[0003] Hair color, thickness, and texture are determined by the middle layer, the cortex. This layer contains the fibrous protein keratin, as the cortex is filled with it. The cortex encloses the medulla. The third, outermost, and final layer of the hair is the cuticle. The cuticle is the dead, overlapping layer. It determines the hair structure and porosity. Hair texture can be curly or straight, and porosity can be low, medium, or high. The higher the porosity, the better the moisture absorption.

[0004] When hair is straightened, the hydrogen bonds in the protein layer of the hair shaft are broken, making the hair malleable and allowing its shape to be temporarily changed. The result is smoother hair due to the necessary heat.

[0005] Today, hair straighteners have undergone numerous developments to meet people's needs. The first hair straightener consisted of two metal rods arranged like tongs, which could press firmly against the hair to straighten it. Later, materials such as ceramic, titanium, and tourmaline were used to prevent excessive heating from the metal rods. Heat-insulating materials such as rubber and heat-resistant plastics were also used to reduce skin contact with the overheated plates and improve grip.

[0006] Traditionally, current models have manual temperature controls or toggle switches that allow the temperature to be adjusted manually as needed. This can have a positive or negative impact on hair health and the time required. At lower temperatures, hair health is not compromised, but the straightening process takes a very long time. Conversely, while it takes less time, the hair damage is significant and permanent.

[0007] To address the above-mentioned deficiencies, the present invention presents an advanced, cost-effective, practical, safe, and precise system for determining the required temperature based on hair type. The present invention effectively overcomes the above-mentioned problems, limitations, and disadvantages. OBJECT OF THE INVENTION

[0008] The main objective of the present invention is to provide a hair straightener that uses artificial intelligence to precisely determine the temperature required for each hair type and automatically spray heat protection spray onto the hair.

[0009] Another object of the present invention is to provide a system for precise hair type classification with a recognition accuracy of up to 98%.

[0010] Another object of the present invention is to provide a system that allows the PID controller to effectively adjust the temperature of the straightening plates to the user's hair type.

[0011] Another object of the present invention is to provide a system with an LED display that indicates the hair type and the temperature to which the straightener plates should be heated, ensuring complete transparency to the user.

[0012] Another object of the present invention is to provide a system and product that is user-friendly, accessible, and cost-effective, allowing for widespread acceptance and use by individuals and organizations in the beauty sector.

[0013] Another object of the present invention is to provide a system in the hair straightener that automatically sprays heat protectant onto the hair. This eliminates the tedious manual application of the product and reduces the time required. The goal is to automatically spray the heat protectant using a motor system so that it is evenly applied to each strand of hair.

[0014] These and other objects and advantages of the present invention will become apparent from the following detailed description taken in conjunction with the accompanying block diagram. SUMMARY

[0015] The various embodiments of the present invention disclose a hair straightener with an automatic heat protection spray system for preventing hair damage during straightening. The device has an image acquisition system. This includes a camera sensor system. The camera system captures the person's hair. The resulting image undergoes preprocessing, noise reduction, feature extraction, image optimization, and image acquisition to improve quality and accuracy using the image as input.

[0016] The integration of AI, machine learning, and deep learning models such as YOLO and CNN methods is used to determine hair type. The integration of predefined instructions and control mechanisms such as PID calculates and regulates the optimal temperature for the detected hair type. Pump spray and motors spray the heat protectant according to predefined instructions. The LED display shows the temperature and the user's hair type.

[0017] The hair straightener automatically detects the user's hair type and applies the heat to the straightening plates accordingly. An automatic spray system distributes heat protection evenly to each strand of hair. The system uses advances in image processing, computer vision, and deep learning to precisely analyze images, distinguish between different hair types, and distribute heat protection accordingly.

[0018] The present invention comprises an image recognition system that analyzes and recognizes hair type using hair images and algorithms from real users. This system comprises several steps or modules, namely, the use of a camera system to obtain input, identification of the hair type, determination of the optimal temperature to be applied to the hair strands, control of the plates based on the derived output at the exit of the previous steps, control of the screen that can display temperature changes, and finally, a spray system that operates with the aid of motors to spray the heat protectant according to the hair type.

[0019] In the first module, the camera module, we capture the user's hair structure using a camera system. This is done using an image acquisition system that creates images of the hair strand. The second module uses automatic learning models, image processing, and deep learning to process the input image using provided training data and predict the exact result. In our case, this corresponds to the person's hair type. The model used in this invention only works after using CNN, which we trained with multiple hair type images, and deploying it in real-world test cases. It allows us to accurately determine a person's hair type. After determining the hair type, the next module calculates and determines the appropriate temperature for that hair type.The PID (proportional-integrated-derivative) algorithm used for this purpose precisely combines the coefficients of proportion, integration, and derivative to determine the appropriate temperature for each hair type. In the next module, the temperatures selected by the model are visualized on an LED screen, and the metal plates are heated to the desired temperature using the controls. In the final step, when the user places the straightener on the strand of hair, a heat protectant spray is evenly sprayed onto the hair. The heat protectant is housed in a rechargeable compartment and is applied using pumps and motors.

[0022] The various embodiments, as well as further developments and features, are explained in the following detailed description using non-limiting details. The depiction of processing techniques for known components is omitted in order not to unnecessarily obscure the embodiments described herein. The examples used herein are intended to facilitate understanding of the possible applications of the embodiments described herein and to enable those skilled in the art to implement the embodiments described herein.

[0023] The various embodiments of the present invention describe a hair straightening device (10) with an automatic heat protection spray system for preventing hair damage during straightening. The device comprises an image capture system, a button, a controller, a power cord, and a spray system. The image capture system includes a camera sensor system. The camera system captures the person's hair. The resulting image undergoes preprocessing, noise reduction, feature extraction, image enhancement, and image capture to improve the quality and accuracy of the image. The integration of AI, machine learning, and deep learning models such as YOLO and CNN methods serves to determine hair type.

[0024] Fig. shows the top view of a hair straightener with an automatic heat protection spray system according to an embodiment of the present invention.

[0025] Predefined instructions and control mechanisms (4) such as PID calculate and regulate the optimal temperature for the detected hair type. Pump spray and motors spray the heat protectant according to predefined instructions. The LED display shows the temperature and the user's hair type. The hair straightener automatically detects the hair type and heats the straightening plates accordingly. An automatic spray system distributes the heat protectant evenly to each strand of hair.

[0026] Fig.shows the bottom view of a hair straightener with an automatic heat protection spray system according to an embodiment of the present invention. The system uses state-of-the-art image processing, computer vision, and deep learning to precisely analyze images, distinguish between different hair types, and dispense and spray the appropriate heat protectant. The present invention comprises an image recognition system that analyzes and recognizes hair type based on hair images and algorithms from real users. The system comprises several steps or modules: A camera system detects the hair type, determines the optimal temperature for the hair strands, and controls the plates based on the determined values. After the previous steps are completed, a display controls the temperature changes and a spray system that sprays the heat protectant depending on the hair type.

[0027] In the first module, the camera module, a camera system (2) captures the user's hair structure. This is done using an image acquisition system that creates images of the hair strand. The second module is the application of automatic learning models, image processing, and deep learning to process the input image using provided training sets and predict the exact result. In our case, the result is the person's hair type. The model used in this invention only works if we use CNN, where we trained the model with multiple hair type images. When deployed in real test cases, the model allows us to accurately determine a person's hair type. After determining the hair type, the next module moves on to calculate and determine the appropriate temperature for that hair type.The algorithm used for this is PID (proportional-integrated derivative), which precisely combines the coefficients of proportion, integration and derivative to derive an accurate temperature suitable for that particular hair type.

[0028] In the next module, the temperatures selected by the model are visualized on an LED screen, and the metal plates are heated to the desired temperature using the controls. In the final step, when the user places the straightener on the strand of hair, a heat protectant spray is evenly sprayed onto the hair. The heat protectant is contained in a rechargeable container and is applied using pumps and motors.

[0029] The device (10) is configured to differentiate between different hair types and heat the straightening plates using several algorithms depending on the hair type. In addition, it features an automated pumping system that sprays the heat protectant onto the respective hair. The system increases user efficiency and satisfaction by reducing straightening time and minimizing overheating damage. By precisely detecting and classifying the hair type depicted in the images, the system enables individual adjustment of the straightener to the user's hair type, thus improving the user experience. According to one embodiment of the present invention, the hair straightener features an image recording device (2), for example a camera, integrated into or connected to the device.The algorithm running in the background of the device uses the image capture device to capture one or more hair images of a person with a specific hair type. In addition to a live image, a pre-printed image of the user in front of the camera or image capture device can also be used as input and passed to the algorithm to distinguish the hair type.

[0030] The hair straightener with hair type-dependent temperature adjustment and automatic heat protection spray system offers users a personalized and positive experience, as the innovation adapts to individual hair needs.

[0031] This hair straightener with hair type-dependent temperature adjustment and automatic heat protection spray system (7) reduces the manual effort of temperature adjustment, which leads to overheating and hair damage if the setting is incorrect (when the temperature is higher than that required by the hair).

[0032] It reduces the time required for straightening and styling and gives the hair a natural and healthy look - unlike conventional straighteners, which can damage the hair or make it look unhealthy if overused.

[0033] Complete transparency towards users is important. They have the right to know which temperature they selected and why. This hair straightener with hair-type-dependent temperature adjustment and an automatic heat protection spray system features an LED display that shows the temperature setting and its changes. This gives the user a sense of security when using the invention.

[0034] Using a manual straightener and heat protectant spray separately is time-consuming, and manually applying the heat protectant spray can sometimes be messy. To avoid this, the present invention features integrated heat protectant spray technology that reduces this effort.

[0035] In one embodiment, a control system and deep learning algorithms are used to determine the optimal and precise temperature required for rapid straightening of the hair. The device classifies hair into at least four types: straight, wavy, curly, and frizzy. It also considers density, frizz, and similar factors to enhance the user experience. The heat protectant is liquid and can be refilled and stored in a reservoir.

[0036] The examples of the present invention described above are for illustrative purposes only. Although the present invention has been described using a specific example, numerous modifications are possible without substantially departing from the teachings and advantages of the subject matter described herein. Further substitutions, modifications, and changes are possible without departing from the spirit of the present solution. All features disclosed in this description (including the appended claims, the abstract, and the drawings) and / or all steps of a method or process disclosed therein may be combined in any way, except for combinations in which at least some of these features and / or steps are mutually exclusive.Although the embodiments described herein are described with reference to various specific embodiments, it will be understood by those skilled in the art to implement the embodiments described herein with modifications.
