Description

Technology Field

[0001] The present invention relates to a wearable hair dryer, and more specifically, to a wearable hair dryer comprising a variable airflow structure. Background Technology

[0002] Most commonly used hair dryers are designed to be held and operated directly by the user's hand. This design presents the inconvenience of requiring the user to use one hand to hold the dryer while drying their hair, leaving them to comb or style with only the other hand. In particular, for users with long or thick hair, it is difficult and time-consuming to adjust styling with only one hand. Additionally, holding the dryer for extended periods increases fatigue in the wrist and arm.

[0003] To alleviate this inconvenience, some users place the hair dryer on a desk or shelf, or utilize a separate wall-mounted stand. However, this method makes it difficult to precisely control the direction of the airflow and to dry the entire hair evenly. Additionally, because the air is directed only from a fixed position, problems may arise where certain areas become over-dried or, conversely, remain insufficiently dried.

[0004] Although some wearable hair dryers have been developed, existing models merely provide the function of spraying air in a constant direction, with limited ability to adjust the airflow to the user's desired direction. While there are many cases where air needs to be directed in various directions depending on the user's hair shape and condition, existing products struggled with such detailed control, limiting their effectiveness in drying hair.

[0005] Furthermore, existing wearable hair dryers had many inconveniences regarding their wearing method. Some products were heavy or bulky, making it difficult for users to wear them for extended periods, and movement was often restricted after putting them on. Lowering or turning the head while wearing the device was uncomfortable, which resulted in the problem of not being able to use the device freely for long durations.

[0006] There was also insufficient consideration for the parts that come into close contact with the user's skin. Some existing products had inadequate heat insulation, resulting in instances where heat transferred from the dryer body came into direct contact with the user's skin. This caused discomfort during use or, in severe cases, posed a risk of low-temperature burns. To prevent this, the inconvenience of having to attach additional insulation pads arose.

[0007] The control method for adjusting wind intensity and direction can also be pointed out as a problem with existing products. Some existing wearable hair dryers required button operation, but they had the disadvantage of being difficult for users to operate because the buttons were small or inappropriately positioned. In addition, button operation made it difficult to continuously adjust wind intensity, and often required setting it only to fixed levels, resulting in low user convenience.

[0008] There was also an issue requiring improvement in the air intake method. Some existing wearable hair dryers had fixed air intake positions, which sometimes resulted in poor airflow depending on the user's wearing position or the surrounding environment. In particular, if collars or hair blocked the intake, hindering airflow, there was a possibility of reduced performance or overheating. This lowered the product's durability and could cause device failure during prolonged use.

[0009] Existing products also lacked connectivity with smart features. While many modern electronic devices are being developed to be used more conveniently by connecting with smartphones, most existing wearable hair dryers were designed to operate independently. Consequently, users had to manually operate buttons to change the direction of the airflow or adjust the intensity, and remote control functions were often not provided. This led to problems such as users having to maintain a specific posture or experiencing discomfort while wearing the device.

[0010] Existing technologies for controlling airflow direction also suffered from a lack of practicality. Some products had a fixed structure that allowed rotation only at a certain angle, or had a limited range of rotation, making it difficult for users to adjust the airflow in their desired direction. Since the required airflow intensity and direction for drying hair can vary depending on the area, existing technologies lacked the functionality to effectively control these factors.

[0011] Consequently, conventional wearable hair dryers suffered from issues such as poor wearing comfort, difficulty in freely adjusting airflow direction, significant fatigue during prolonged use, and inadequate skin protection. Additionally, the control method for adjusting airflow intensity and direction was inconvenient, there was a lack of connectivity with smart features, and poor air intake could lead to reduced device performance.

[0012] The present invention aims to solve the problems of the conventional technology. The present invention allows for comfortable wear while enabling the free adjustment of the air discharge direction according to the user's hair condition, and provides a function for precisely controlling the intensity and direction of the wind. Furthermore, it includes an insulating structure for skin protection to minimize discomfort during wear and maximizes user convenience by linking with a smartphone. Through this, various inconveniences associated with the conventional technology are resolved, and more efficient operation of the hair dryer is enabled. Prior art literature

Specific details for implementing the invention

[0023] Preferred embodiments of the present invention will be described in detail below with reference to the drawings. Prior to this, terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, but should be interpreted in a meaning and concept consistent with the technical spirit of the present invention.

[0024] Throughout this specification, when it is stated that one component is located "on" another component, this includes not only cases where one component is in contact with another component, but also cases where another component exists between the two components. Throughout this specification, when it is stated that a part "includes" a component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0025] FIG. 1 shows a perspective view of a wearable hair dryer according to one embodiment of the present invention, and FIG. 2 shows a block diagram of a wearable hair dryer according to one embodiment of the present invention.

[0026] Referring to these drawings, the wearable hair dryer (100) according to the present embodiment is equipped with a dryer body part (110) of a specific structure, an air flow part (120), and an operation control part (130), so that it can be easily worn on a part of the body and operated, and can be easily operated through a simple button operation method and a dial operation method, thereby solving the inconvenient problem of the conventional technology that required using both hands to dry hair, and can selectively spray air in the direction and location to be concentrated dried, so that the time required for drying hair can be significantly shortened, and furthermore, can provide a wearable hair dryer equipped with smart functions that can be operated in conjunction with the user's smartphone.

[0027] Hereinafter, each component constituting the wearable hair dryer (100) according to the present embodiment will be described in detail with reference to the drawings.

[0028] Specific configuration and role of the dryer main body (110)

[0029] The dryer body (110) has a tubular structure formed to wrap around the user's neck and be draped over both shoulders. This structural feature ensures that the dryer is securely fixed when worn by the user and prevents it from easily slipping off or shaking during movement. Additionally, the dryer body (110) includes an internal air flow path, designed to maintain a smooth flow after air intake. This air flow path maintains a constant air movement path internally and facilitates smooth air discharge.

[0030] Air intake ports are formed at both ends of the main body (110) of the dryer to allow external air to be drawn in. The position of the air intake ports is arranged to allow for efficient air intake depending on the user's wearing condition. The air intake ports may include a filter to prevent the entry of foreign substances, and the filter may be designed to be replaceable after a certain period of use. This prevents dust or foreign substances from the external environment from entering the interior and allows cleaner air to be drawn in.

[0031] A skin contact surface (112) that comes into direct contact with the user's shoulder and neck is formed on the lower surface of the dryer body (110). The skin contact surface (112) is designed to make soft contact with the user's skin and is composed of a material having thermal insulation properties to prevent direct heat transfer. Additionally, the skin contact surface (112) may be composed of a fabric material with excellent moisture absorption and breathability to maintain a comfortable fit even when sweat is generated. This minimizes an unpleasant wearing sensation even when worn for a long time.

[0032] An air injection surface (113) having an air outlet (111) formed therein is located on the outer surface of the main body (110) of the dryer. The air injection surface (113) is a part through which air is discharged, and may include a structure capable of controlling the opening direction of the air outlet (111) and the injection intensity. Additionally, the air injection surface (113) is made of a material with excellent durability and resistance to heat, and a resin material having waterproof properties is applied so that it can be used without deformation even in a humid environment.

[0033] The dryer body (110) is made of a lightweight and highly durable material for the convenience of the user. It can be made primarily using a polymer synthetic resin with excellent heat resistance, and the internal structure is designed to efficiently maintain airflow. In addition, the length and curvature of the dryer body (110) can be optimized to fit the user's neck circumference and shoulder width, and can be flexibly adjusted according to the user's body size by applying a structure capable of elastic deformation.

[0034] Air outlet (111)

[0035] The air outlets (111) are a plurality of outlets formed at regular intervals on the central outer surface of the dryer body (110). The air outlets (111) are configured so that heated air can be smoothly discharged to the outside through the internal air flow section (120). The size and shape of the air outlets (111) are designed to distribute the air flow evenly, and the discharge angle can be adjusted to effectively dry the user's hair.

[0036] The air outlet (111) includes a structure that can control the direction of the wind by linking with the variable spray direction section (123) inside the air flow section (120). Through this, the user can concentrate the wind on a specific area or discharge the air at a desired angle. This structure is particularly advantageous for rapidly drying specific parts of the hair and enables a customized drying method for the user.

[0037] The air outlets (111) are formed in a continuously arranged form and are positioned at regular intervals along the length direction of the dryer body (110). This arrangement allows air to be discharged uniformly and serves to prevent only specific areas from being excessively dried. Additionally, the opening area of ​​the air outlets (111) can be adjusted according to the user's needs, and some models may include a slide-type control device that can adjust the degree of opening.

[0038] A fine filter or protective mesh may be installed inside the air outlet (111) to prevent foreign matter from entering. This protective structure prevents the user's hair from being sucked into the air outlet (111) and protects the internal parts from contamination even during long-term use. Additionally, the protective mesh is designed to be detachable to facilitate cleaning and maintenance.

[0039] The air outlet (111) is made of a highly durable material and is made of a heat-resistant material so as not to deform even at high temperatures. Generally, a silicone-coated synthetic resin or a polymer material with excellent heat resistance may be used, and additional heat-resistant treatment or a heat dissipation structure may be applied to areas where heat is concentrated. This prevents deformation of the air outlet (111) even during long-term use and ensures continuous performance.

[0040] Skin contact surface (112)

[0041] The skin contact surface (112) is a structure that is laminated or attached to the lower surface of the dryer body (110) and is a part that comes into direct contact with the user's shoulder and neck area. Since it is a part that comes into direct contact with the user's skin, providing a comfortable fit when worn is an important factor. To this end, the skin contact surface (112) is made of a soft and flexible material and is designed so as not to irritate the skin even when used for a long time.

[0042] The skin contact surface (112) performs the function of blocking heat generated inside the dryer body (110) from being directly transferred to the user's skin. To this end, it is composed of an insulating material with low thermal conductivity, and in particular, materials with insulating properties and cushioning, such as silicone, neoprene, and special synthetic rubber, may be applied. Through this insulating material, the user can use it safely without feeling skin burns or discomfort even while high-temperature air is being discharged.

[0043] Since the skin contact surface (112) may be directly exposed to the user's sweat and skin oil, it is made of a material that takes hygienic care into consideration. By applying a material with antibacterial and waterproof functions, it is made so that it can be maintained hygienically even with long-term use, and is manufactured with a structure that is resistant to water or moisture and easy to clean. In addition, in some embodiments, the skin contact surface (112) is designed to be detachable so that it can be replaced or cleaned as needed to maintain a hygienic state.

[0044] The surface of the skin contact surface (112) must have non-slip properties. To prevent the dryer body (110) from easily slipping off the neck or changing position while the user is moving, a fine textured pattern or a rubber coating may be applied to the skin contact surface (112). This surface treatment allows the device to remain securely in place even while the user is active, and helps it to fit naturally, especially for users with different neck circumferences.

[0045] The skin contact surface (112) is designed based on ergonomic design so that it can naturally fit the curve of the user's neck and shoulders. While general wearable devices are often made in a simple flat shape, the skin contact surface (112) of the present invention can be made in a three-dimensional structure with applied curvature, taking into account the user's body shape. Through this, it fits naturally without pressure when worn, and fatigue can be minimized even when used for a long time.

[0046] Air jet surface (113)

[0047] The air injection surface (113) is structured to be laminated or attached to the remaining part of the dryer body (110), excluding the skin contact surface (112), and includes a portion in which an air outlet (111) is formed. Since the air injection surface (113) is a surface through which heated air is discharged, it is made of a material with excellent heat resistance that does not deform even at high temperatures. In addition, considering that the user's hair comes into direct contact with the air outlet (111), a soft surface treatment is applied to prevent the user's hair from getting tangled or snagged.

[0048] The air injection surface (113) serves to efficiently release thermal energy transferred from the inside to the outside. For this purpose, a heat-resistant resin or metal coating may be applied, and in some embodiments, heat dissipation treatment is used to ensure that heat is evenly distributed rather than concentrated in specific parts. Additionally, the arrangement pattern of the air outlets (111) can be optimized to maximize the air dispersion effect so as to maintain a smooth airflow.

[0049] The air blower surface (113) is made of a material with waterproof properties. Since the hair dryer is used to dry the user's hair, it is highly likely to be exposed to water or moisture during use. Accordingly, the air blower surface (113) is protected from damage by water or moisture by applying a waterproof synthetic resin or silicone coating. This allows the user to safely use the product even after bathing or in humid environments.

[0050] Air outlets (111) are formed in a specific pattern on the air injection surface (113) to ensure smooth airflow. The size and spacing of the air outlets (111) are designed for optimal drying effects and may include a guide structure to concentrate the injected air in a specific direction. In particular, in some embodiments, a sliding cover structure capable of adjusting the degree of opening of the air outlets (111) is applied so that the user can adjust the air discharge as needed.

[0051] Since the air injection surface (113) is a part that comes into direct contact with the user's hair when worn, a function to prevent static electricity generation may be added. To this end, an anti-static coating may be applied or an antibacterial material may be used, and a fine dust filter may be included inside the air outlet (111). Through this design, the air injection surface (113) can be kept more hygienic and can provide an efficient drying effect while minimizing damage to the user's hair.

[0052] Specific configuration and role of the air flow section (120)

[0053] The air flow unit (120) is a core component that performs the function of drawing in air from inside the wearable hair dryer, heating it, and then spraying it out through the air outlet (111). The air flow unit (120) can control the flow of air according to the user's settings and is configured to allow adjustment to a desired temperature, including an air heating function. Through this, the user can select and use the optimal airflow according to the condition of the hair and environmental conditions.

[0054] The air flow section (120) is positioned inside the dryer body (110) and consists of an air intake fan (121), an air heating section (122), and a spray direction variable section (123). The air intake fan (121) rapidly draws in external air and introduces it into the interior, and the air heating section (122) heats the introduced air to a set temperature. Subsequently, the heated air is adjusted in a specific direction through the spray direction variable section (123) and sprayed out through the air outlet (111).

[0055] The air flow section (120) is designed to optimize airflow. The internal flow path is designed to allow air to move smoothly with minimal resistance, and efficient air compression technology may be applied to minimize noise and energy consumption. Additionally, the air flow section (120) may include a pressure regulator to maintain a constant pressure of the incoming air. This allows for the stable provision of a constant wind intensity to the user.

[0056] The air flow unit (120) may include a smart control function. It can remotely adjust the wind speed and temperature by linking with the user's smartphone, and is designed to automatically operate without repetitive operation by saving the user's preferred settings. In addition, it may include a function to automatically adjust the optimal wind by linking with a sensor that detects ambient temperature and humidity. Through this, the user can operate the hair dryer more conveniently.

[0057] The air flow section (120) is designed to facilitate maintenance and cleaning. Filters may be applied to the air inlet and the internal air flow path to prevent dust and foreign matter from accumulating, and the filters may be designed with a detachable structure so that they can be easily replaced at regular intervals. Additionally, the components installed inside the air flow section (120) are made of a highly durable material to ensure stable operation without performance degradation even during long-term use.

[0058] air intake fan (121)

[0059] The air intake fan (121) is a component that performs the function of drawing in external air from the air flow section (120) and introducing it into the interior of the dryer body section (110). The air intake fan (121) is designed to control the speed of air intake and can change the rotation speed according to the user's settings. Through this, the airflow can be controlled to more precisely control the wind intensity and temperature.

[0060] The air intake fan (121) is positioned at both ends of the dryer body (110) and is designed to efficiently draw in air even while the user is wearing it. The structure of the fan is aerodynamically designed to optimize airflow and operates in conjunction with a low-noise motor to minimize noise while maintaining high suction power. This allows the user to use the product comfortably even in a quiet environment.

[0061] The air intake fan (121) may include a filter to prevent the entry of foreign substances. The filter serves to prevent external dust, hair, and other contaminants from entering the interior, and may be designed to be detachable so that it can be replaced or washed after a certain period of use. This extends the lifespan of internal components and allows for the maintenance of consistent air quality even during long-term use.

[0062] The air intake fan (121) is designed with energy efficiency in mind. The fan blades are optimized to induce maximum air intake with minimum power, and the motor operates in a low-power, high-performance manner to reduce battery consumption. In particular, since battery efficiency is an important factor when operating wirelessly, it is important to minimize the power consumption of the fan.

[0063] The air intake fan (121) is made of a highly durable material and has heat dissipation treatment applied so that it does not overheat even when operated for a long time. Generally, high-strength plastic or aluminum alloy may be used, and a low-friction bearing is applied to the fan's rotation axis so that it can rotate smoothly even when used for a long time. Through this, the air intake fan (121) maintains stable performance and allows the user to operate the hair dryer efficiently for a long period of time.

[0064] Air heating unit (122)

[0065] The air heating unit (122) is a component mounted inside the air flow unit (120) that performs the function of heating air drawn in through the air intake fan (121) to a set temperature. When the user selects a desired temperature, the air heating unit (122) heats the air to that temperature and sprays it through the air outlet (111). The air heating unit (122) is designed to have fast responsiveness and high thermal efficiency so that it can reach the set temperature within a short time after turning on the power. This allows the user to use warm air immediately without waiting time.

[0066] The air heating unit (122) includes an electric resistance type heating element inside, and generally, a PTC (Positive Temperature Coefficient) heater or a heating element using nichrome wire can be used. Since the PTC heater has the characteristic of automatically regulating the current flow when the temperature exceeds a set value, it prevents overheating and enables stable temperature control. In addition, the PTC heater has the advantage of providing uniform heat while minimizing power consumption due to its high energy efficiency.

[0067] The air heating unit (122) includes an overheating prevention function for the safety of the user. It is equipped with a temperature sensor inside and performs the function of automatically cutting off the power when the set temperature is exceeded. In addition, it may include a protection function that automatically lowers the temperature or temporarily stops operation if it operates continuously for a certain period of time. Such safety devices prevent fire or product damage even during long-term use.

[0068] The heating element of the air heating unit (122) is designed in an optimized shape so as not to obstruct the flow of air. Generally, the air heating unit (122) is located inside the air flow path and is arranged so that the air can be heated uniformly along the direction of air intake. In addition, the flow path design is optimized so that the heated air does not stagnate inside, thereby maintaining efficient heat transfer and a uniform temperature distribution.

[0069] The air heating unit (122) may include a multi-stage temperature control function to provide various temperatures according to the user's settings. The user can adjust the temperature of the wind by operating the temperature control button (130c) of the operation control unit (130), and in certain models, a function to remotely adjust the temperature by linking with a smartphone may also be provided. Through this, the user can select and use the optimal temperature according to the season or the condition of the hair.

[0070] Variable injection direction part (123)

[0071] The variable spray direction unit (123) is a component mounted inside the main body of the dryer (110) that performs the function of controlling the direction of air sprayed through the air outlet (111). The variable spray direction unit (123) is controlled to concentrate the air in a specific direction or spray over a wide range according to the user's settings. Through this, the user can quickly dry hair in a specific area and perform the desired styling more easily.

[0072] The injection direction variable part (123) includes a rotating cylinder (123a), and a through hole (123b) of a certain size is formed on the inner surface of the cylinder. The through hole (123b) is linked with the air outlet (111) and serves to determine the external injection direction of air. When the user changes the injection direction, the rotating cylinder (123a) rotates, changing the position of the through hole (123b) and changing the direction in which air is discharged.

[0073] The rotational operation of the injection direction variable unit (123) is performed through the rotation angle changing gear unit (123d). The rotation angle changing gear unit (123d) is composed of a rack gear (123c) and a pinion gear, and rotates the gear by receiving power from the rotation drive unit (123e). Through this, when the user operates the direction control dial (130b) or sets it remotely via a smartphone, the angle of the injection direction variable unit (123) is automatically adjusted.

[0074] The variable spray direction unit (123) is designed to concentrate air on a specific area while maintaining a smooth airflow. It may include a guide structure that regulates the airflow velocity to a constant level, thereby inducing the air to be sprayed strongly in a specific direction. Additionally, the variable spray direction unit (123) may include a locking function to maintain a direction set by the user, and may also include a function to automatically return to its original position after a specific time.

[0075] The variable spray direction unit (123) can be designed to suit various usage environments and may include a multi-stage control function to operate differently according to the style preferred by the user. For example, a 'concentration mode' that sends air intensively to the area desired by the user and a 'diffusion mode' that distributes air evenly over the entire area may be provided. Additionally, an 'automatic rotation mode' that moves periodically at a specific angle may be included, allowing the user to effectively dry their hair without any separate operation.

[0076] In-situ rotation cylinder (123a)

[0077] The in-situ rotation cylinder (123a) is a cylindrical structure mounted inside the dryer body (110) and plays a key role in controlling the external communication direction of the air outlet (111). This cylinder has an outer diameter equal to the inner diameter of the dryer body (110) and is designed to rotate in place inside the dryer body (110). The rotation of the cylinder is precisely adjusted to a specific angle according to the user's operation signal, allowing the direction of air injection to be varied.

[0078] The in-situ rotation cylinder (123a) is linked to the rotation angle changing gear unit (123d) through a pinion gear that meshes with the rack gear (123c) formed inside. When the user operates the direction control dial (130b), power from the rotation drive unit (123e) is transmitted to rotate the cylinder, and in this process, the direction of air discharge changes. Additionally, a position locking function may be included so that the cylinder can stop at a certain position, and an automatic return function that returns to the original position after a specific time may also be applied.

[0079] The in-situ rotating cylinder (123a) must be made of a material with excellent heat resistance, and generally, a heat-resistant polymer or aluminum alloy that does not deform even at high temperatures is used. The cylinder is precision machined so that it does not wear out due to friction even during long-term use, and a low-friction coating may be applied to the interior. Through this design, the cylinder can rotate smoothly and precisely and maintain stable performance even during long-term use.

[0080] Penetrating hole (123b)

[0081] The through hole (123b) is an opening formed at a specific location of the in-situ rotating cylinder (123a) and serves to determine the path through which air is ejected to the outside in conjunction with the air outlet (111). The through hole (123b) has a fixed penetration area, and as the cylinder rotates, the alignment with the air outlet (111) changes, thereby allowing the direction of air discharge to be controlled. Through this, the user can direct the wind only in a specific direction or disperse it in multiple directions.

[0082] The through hole (123b) is designed in an aerodynamically optimized shape so as not to obstruct the airflow. The inner surface is machined smoothly to maintain a smooth airflow and is designed to minimize pressure loss during the process of air discharge. Additionally, a function to adjust the opening area of ​​the through hole (123b) may be included, which can thereby control the speed and intensity of air discharge.

[0083] The through holes (123b) can be applied in various sizes and shapes according to the user's settings, and may also be formed in the form of multiple openings as needed. For example, in some embodiments, multiple through holes (123b) may be arranged in a single cylinder to allow the user to select the desired air discharge pattern. This enables customized operation, such as drying only specific areas intensively or evenly dispersing air over a wide area.

[0084] Rack gear (123c)

[0085] The rack gear (123c) is a gear structure formed continuously along the inner circumference of the in-situ rotating cylinder (123a) and meshes with the rotation angle changing gear part (123d) to perform the function of rotating the cylinder in place. The rack gear (123c) has a gear-shaped structure arranged continuously in a straight line and is coupled with a pinion gear to ensure smooth rotational movement. Through this, when the user operates the direction control dial (130b), the rotation of the cylinder is precisely controlled, allowing the direction of air discharge to be changed.

[0086] The rack gear (123c) is precision machined to have teeth of a constant spacing and size and is made of a durable material resistant to friction and wear. Generally, engineering plastics (e.g., POM, nylon) or lightweight metals (e.g., aluminum alloy) with excellent heat resistance and wear resistance are used, and a surface treatment may be applied to prevent the gear's performance from deteriorating due to friction even during long-term use. Additionally, a special coating may be applied for a low-noise design, thereby minimizing noise and vibration when operated by the user.

[0087] Since the rack gear (123c) must maintain precise meshing with the rotation angle changing gear part (123d), it is designed so that the clearance between the gears is minimized. To this end, the tooth shape of the gear is machined to make optimal contact with the pinion gear, and lubrication or friction reduction treatment may be applied so that the gear's operation can be smooth. Through this design, the rack gear (123c) can precisely rotate the cylinder in the direction desired by the user and effectively control the direction of air discharge.

[0088] Rotation angle changing gear part (123d)

[0089] The rotation angle changing gear unit (123d) is a component that includes a pinion gear structure and performs the function of transmitting rotational force transmitted from the rotation drive unit (123e) to the rack gear (123c). The rotation angle changing gear unit (123d) is positioned inside the dryer body (110) and may include a multi-stage control function to precisely adjust the rotation angle of the cylinder. Through this, the user can finely adjust the direction of air injection, and control is possible such as drying a specific area intensively or diffusing the air over a wide area.

[0090] The rotation angle changing gear section (123d) is designed so that the pinion gear and the rack gear (123c) mesh precisely, and the size and shape of the gear are optimized to maintain smooth rotational motion. The gear is made of high-strength engineering plastic or metal alloy, and a surface hardening treatment may be applied to increase durability. In addition, a lubricant may be applied to reduce friction of the gear, and it is designed to minimize wear even during long-term use.

[0091] The rotation angle changing gear unit (123d) may be operated automatically according to the operation signal of the operation control unit (130), and may include a function to be fixed at a specific angle according to the user's settings. For example, when the user operates the direction control dial (130b), the gear unit rotates the cylinder at a set angle, and a stopper device may be applied to stop it at a specific position. Through this, the user can precisely control the wind in the desired direction and obtain a more efficient drying effect.

[0092] rotary drive unit (123e)

[0093] The rotary drive unit (123e) is a component that provides rotational driving force to the rotation angle change gear unit (123d) to rotate the in-situ rotation cylinder (123a) to a desired angle. The rotary drive unit (123e) is generally designed to enable precise rotational control by including a small motor and a gear reduction device. This allows the cylinder to rotate to an accurate angle when the user operates the direction control dial (130b) or operates it remotely via a smartphone, thereby allowing the direction of the wind through the air outlet (111) to be adjusted.

[0094] The rotary drive unit (123e) is configured to control a precise rotation angle using a small DC motor or a stepper motor. When a stepper motor is used, it can rotate finely to an angle set by the user, and can be fixed in a specific direction or adjusted in fine steps. In addition, the rotary drive unit (123e) may include a gear reduction device, thereby ensuring stable transmission of driving force while minimizing noise and vibration. Through this design, the user can control the spray direction in a quiet and smooth manner.

[0095] The rotary drive unit (123e) may include an overload and malfunction prevention function, and may be equipped with a protection function that automatically stops operation when a certain torque is exceeded. Additionally, a position detection sensor may be included, which allows the device to be controlled to stop precisely at an angle set by the user. For example, the air outlet (111) may be set to be completely blocked or opened at a specific angle, and a function to automatically adjust the spray direction by rotating periodically may also be implemented. Through this, the user can effectively control the airflow in the desired direction and operate the wearable hair dryer in a convenient and intuitive manner.

[0096] Specific configuration and role of the operation control unit (130)

[0097] The operation control unit (130) is a core component that controls the overall operation of the wearable hair dryer and performs the function of receiving input signals from the user and operating the air flow unit (120) and the spray direction variable unit (123) based on the input signals. The operation control unit (130) can be designed to allow not only direct operation by the user but also remote operation through wireless linkage with a smartphone. Through this, the user can directly operate buttons and dials or set the airflow, temperature, spray direction, etc. of the hair dryer through a smartphone application.

[0098] The operation control unit (130) is mounted on one side of the dryer body (110) in a manner exposed to the outside, and is designed to provide an intuitive interface so that the user can easily operate it. The operation control unit (130) includes a power button (130a), a direction control dial (130b), a temperature control button (130c), etc., and each control unit is operated by the user's finger touch or pressing action. This configuration is designed so that it can be easily operated even while the user is wearing it, and is arranged so that all functions can be operated with one hand.

[0099] The operation control unit (130) is made of a highly durable material and is designed so that its performance does not deteriorate even after prolonged use. In particular, the part that is frequently touched by the user's fingers may be made of a material resistant to friction and contamination, and may also be waterproof and dustproof. Through this, the user can use it safely even in a humid environment, and the button is protected from wear even after prolonged use.

[0100] The operation control unit (130) operates based on electronic circuits and may include a microcontroller (MCU) internally. The MCU analyzes the user's input signal and performs the role of transmitting appropriate control signals to the air flow unit (120) and the injection direction variable unit (123). In addition, the MCU stores the user's settings to maintain the same setting value without repetitive operation, and may also provide a remote control function through Bluetooth or Wi-Fi connectivity with a smartphone.

[0101] The operation control unit (130) is designed with energy efficiency in mind and can be optimized to operate at low power. In particular, since extending battery life is important due to the nature of the wearable product, a circuit design that minimizes standby power can be applied. Additionally, a function may be included that automatically switches to a power-saving mode if the user does not operate it for a certain period of time, or automatically cuts off the power after a certain period of time. This enhances user convenience and prevents unnecessary power consumption.

[0102] Power button (130a)

[0103] The power button (130a) is a control unit that performs the function of turning the power of the wearable hair dryer on and off, and is positioned in a location easily accessible to the user. The power button (130a) is mounted on one side of the dryer body (110) in a form exposed to the outside and is operated by the user's finger touch or pressing action. The size and design of the button are designed for intuitive use and are positioned so that they can be easily operated with one hand.

[0104] The power button (130a) can perform not only a simple on / off function, but also a function to reset specific settings when pressed for a certain period of time. For example, if a user presses the power button (130a) for 3 seconds or more, all settings of the air flow unit (120) and the injection direction variable unit (123) are reset, and the system can be designed to return to the default settings. This allows the user to easily return to the initial settings as needed and to use the default settings immediately without complex operations.

[0105] The power button (130a) is made of a highly durable material and is protected so that the physical performance of the button does not deteriorate even with frequent operation. Generally, a silicone coating may be applied, or a material with waterproof and dustproof functions may be used. In particular, it may be designed with an IP rating (waterproof and dustproof rating) in mind so that it can operate stably even in humid environments, so that the user can use the hair dryer without worry even after showering.

[0106] The power button (130a) may be linked with an LED indicator. When the user turns on the power, an LED light illuminates around the button, allowing visual confirmation that the product is operating normally. Additionally, a function to display the battery status may be added, and if the battery is low, the LED may blink to notify the user that charging is required. Through this visual feedback, the user can intuitively check the current status of the product.

[0107] The power button (130a) can be linked with an energy saving function and may include a function that automatically cuts off the power when not in use for a certain period of time. For example, if the user does not perform any operations for a specific period of time, it may automatically switch to power-saving mode or cut off the power to prevent unnecessary power consumption. This allows the user to use the product more conveniently and contributes to extending battery life.

[0108] Direction control dial (130b)

[0109] The direction control dial (130b) is an operating part that allows the user to control the direction of the wind sprayed from the air outlet (111), and is mounted on one side of the dryer body (110) in a form exposed to the outside. The direction control dial (130b) is designed with a rotary structure and allows the user to change the direction of air spray by turning the dial left and right. When this dial is operated, the spray direction variable part (123) plays the role of adjusting the discharge direction of the air outlet (111) by rotating the in-situ rotation cylinder (123a) at a specific angle.

[0110] The direction control dial (130b) is designed to be intuitively operated by the user. The surface of the dial may have an embossed pattern or a rubber grip, which allows the finger to operate stably without slipping. Additionally, the dial is designed to have a constant resistance when rotated, allowing the user to finely adjust to the desired angle and control the direction so that it does not change suddenly.

[0111] The direction control dial (130b) is linked to the rotation angle change gear unit (123d), and when the user turns the dial, it operates by moving the rack gear (123c) through the pinion gear to rotate the in-situ rotation cylinder (123a) to a specific angle. Through this, the user can freely adjust the direction of the wind to suit the area where they want to dry their hair, and can operate in various ways, such as sending the wind intensively to one spot or dispersing it widely.

[0112] The direction control dial (130b) may include a step-by-step adjustment function that stops at a specific position. For example, a fixed point may be set at regular angles so that the user can add a function to stop at a specific angle when turning the dial. This provides the user with the convenience of not only making fine adjustments but also being able to quickly set to a specific angle and easily set to a frequently used direction.

[0113] The direction control dial (130b) may be linked with smart functions. By connecting to the user's smartphone, the direction of air discharge can be pre-set via an application, allowing the direction of the wind to be automatically adjusted without directly operating the dial. Additionally, the user's preferred direction setting can be saved so that it can be easily used with the same setting in the future. Through this, the user can operate the hair dryer more efficiently and conveniently.

[0114] Temperature control button (130c)

[0115] The temperature control button (130c) is a control unit that performs the function of allowing the user to control the temperature of the wind by operating the air heating unit (122) of the air flow unit (120). This button is mounted on one side of the dryer body (110) in a form exposed to the outside and is designed to be operated by a finger touch or a pressing action. The user can adjust the temperature of the wind step by step by pressing the button, and can set it to various temperatures such as cold wind, lukewarm wind, and hot wind as needed.

[0116] The temperature control button (130c) can provide visual or tactile feedback so that the user can easily recognize it. For example, the LED color may change each time the button is pressed to allow the user to intuitively check the currently set temperature, and the user's sense of operation may be enhanced by applying a structure that provides a slight vibration or click sensation when the button is pressed. This design helps the user quickly recognize and adjust the set value.

[0117] The temperature control button (130c) is linked to the air heating unit (122) and controls the operation of the heating element within the air flow unit (120) according to the temperature set by the user. For example, if the user presses the button to increase the temperature, the output of the heating element, such as a PTC heater or nichrome wire, is increased to raise the temperature of the air, and conversely, if the user presses the button to decrease the temperature, the output of the heating element is reduced to provide lukewarm or cold air.

[0118] The temperature control button (130c) may operate in conjunction with an overheating prevention function. When set above a certain temperature, a safety sensor monitors the temperature of the heating element, and may include a function to automatically adjust the output or cut off the power if the set temperature is exceeded. Through this, the user can safely adjust the airflow to the desired temperature and prevent the risk of overheating even during long-term use.

[0119] The temperature control button (130c) can be linked with smart functions, allowing the user to remotely set the temperature via their smartphone or save their preferred settings. This enables the user to adjust the temperature without directly operating the button and to utilize a function that automatically changes the temperature according to specific usage environments. This smart control function maximizes user convenience and enables more efficient use of the hair dryer.

[0120] 1st group control unit (131)

[0121] The first group control unit (131) is a component that performs the function of individually controlling the spray direction variable unit (123) at a position corresponding to the back of the user's head among the plurality of spray direction variable units (123) mounted inside the dryer main body (110). Through the first group control unit (131), the user can set the air to be sprayed intensively on the back of the head or to block the air outlet (111) in that area. Through this, the user can quickly dry the back of the hair when drying hair and can adjust the airflow intensively in a specific direction as needed.

[0122] The first group control unit (131) is linked with the operation control unit (130), and when the user operates the direction control dial (130b) or operates it remotely via a smartphone, it receives the corresponding signal and performs the function of controlling the variable spray direction unit (123) at the back of the head. If the user wants to dry the back of the head quickly, the air outlet (111) can be operated to be fully opened, and conversely, if the user wants to block the wind from a specific area, the air outlet (111) can be set to be closed.

[0123] The first group control unit (131) may include a multi-stage control function to finely adjust the intensity and direction of the wind. The user may fix the wind at a specific angle, or, if an automatic mode is set, the spray direction may change at regular intervals. For example, if the user sets the "back of the head intensive drying mode," the air outlet (111) is adjusted to a direction optimized for the back of the head, and the wind intensity is automatically controlled to be maintained uniformly.

[0124] The first group control unit (131) may include overheating prevention and user protection functions. Since the back of the head is a relatively heat-sensitive area, it may include a function to automatically lower the air temperature when heated above a certain temperature, or to regulate the air circulation for a certain period of time to prevent heat from concentrating. Through this, the user can use the hair dryer in an optimal environment without discomfort caused by excessive heat.

[0125] The first group control unit (131) can be linked with smart functions and can save the user's preferred settings so that they can be quickly operated with the same settings later. For example, if the user saves a setting to dry the back of the hair with a specific temperature and airflow, it can be configured to be automatically executed under the same conditions later. Through this, the user can efficiently use the hair dryer in the desired way without repetitive operation.

[0126] 2nd group control unit (132)

[0127] The second group control unit (132) is a component that performs the function of individually controlling the spray direction variable unit (123) at a position corresponding to the user's left sideburn area among the plurality of spray direction variable units (123) mounted inside the dryer main body (110). The user can use the second group control unit (132) to concentrate airflow on the left sideburn area or to set the air outlet (111) of that area to be blocked. Through this, the left hairline can be effectively controlled during the styling process, and only the desired area can be selectively dried.

[0128] The second group control unit (132) is linked with the operation control unit (130), and when the user operates the direction control dial (130b) or controls it via a smartphone, it receives the corresponding signal and performs the function of controlling the air outlet (111) in the left sideburn area. The user can finely adjust the direction of the wind when drying the left hairline and can also set it so that the wind is sprayed only on the left side.

[0129] The second group control unit (132) may include a multi-stage control function, allowing the user to finely adjust the angle of the wind or set it to change direction automatically. For example, if a "styling mode" is activated to dry the left sideburn area at a constant angle, the wind can be controlled to rotate and spray along the left hairline at a constant frequency. This function can be particularly useful for users who wish to maintain a precise style.

[0130] The second group control unit (132) includes heat control and safety functions, and can provide a function to automatically control the temperature or airflow when set above a certain temperature. Since the left sideburn area is located close to the user's face, excessively high temperatures can cause discomfort. Accordingly, it is automatically controlled to maintain a constant temperature, and the wind intensity can be set so that it does not increase above a certain level.

[0131] The second group control unit (132) can be linked with a smartphone to allow the user to save desired settings and enable automatic execution with the same settings thereafter. For example, if the user saves a setting to dry the left sideburns by specifying a specific temperature and wind direction, the same settings can be applied by pressing just one button thereafter. Through this, the user can conveniently operate the hair dryer without repetitive operations and effectively satisfy the needs of users who require individual adjustments.

[0132] 3rd group control unit (133)

[0133] The third group control unit (133) is a component that individually controls the spray direction variable unit (123) at a position corresponding to the user's right sideburn area among the plurality of spray direction variable units (123) mounted inside the dryer main body (110). The user can use the third group control unit (133) to concentrate airflow on the right sideburn area or to set the air outlet (111) in that area to be blocked. Through this, the user can effectively tidy up the right hairline during the styling process and selectively dry only the necessary areas.

[0134] The third group control unit (133) is linked with the operation control unit (130) and, when the user operates the direction control dial (130b) or operates it remotely via a smartphone, receives the corresponding signal and performs the function of adjusting the air outlet (111) in the right sideburn area. The user can finely adjust the direction of the wind to adjust the wind required for styling to the optimal position, and if necessary, it is also possible to set the air outlet (111) in a specific area to be completely blocked.

[0135] The third group control unit (133) may include various control functions to enable the user to perform more precise hair styling. The user can fix the airflow at a specific angle, and can also set the direction to change at regular intervals when the automatic mode is activated. For example, if the user selects the "right sideburn intensive drying mode," the air outlet (111) is adjusted to a direction optimized for the right hairline, and the airflow is sprayed and can be maintained automatically for a set time.

[0136] The third group control unit (133) may include temperature control and overheating prevention functions for safety. Since the right sideburn area is adjacent to the user's face, a function to automatically reduce the airflow or adjust the temperature when a certain temperature is exceeded may be applied to prevent the skin from being irritated by excessively high temperatures. Additionally, if air is continuously sprayed for a certain period of time, a function to intermittently adjust the airflow may be applied to provide skin protection and a comfortable user experience.

[0137] The third group control unit (133) can be linked with smart functions and saves the user's preferred settings so that the same settings can be executed quickly thereafter. For example, if the user saves a setting to style the right sideburns with a specific wind speed and direction, the same settings can be automatically applied later via one touch or a smartphone app. Through this, the user can use the hair dryer efficiently and conveniently without repetitive operations, and more precise styling becomes possible.

[0138] As explained above, the wearable hair dryer of the present invention solves the inconvenience of conventional handheld hair dryers and provides a structure that allows the user to use their hands freely. Conventional hair dryers had the problem that combing or styling with the other hand was limited because the user had to hold the main body with one hand. In addition, there was the inconvenience of increased fatigue in the wrist and arm during prolonged use. In the present invention, by applying a wearable structure and designing it to be worn around the user's neck, these problems are solved, and a more convenient hair drying environment can be provided.

[0139] The present invention includes a variable spray direction unit (123) that allows the spray direction to be freely adjusted, thereby solving the problem that conventional wearable hair dryers have a fixed air discharge direction, making it difficult to concentrate air on a specific area desired by the user. Since conventional wearable hair dryers only spray air from a fixed location, there was the inconvenience of the user having to change the angle of their neck or move their body to dry a specific area. In the case of the present invention, by applying a structure utilizing a rotating cylinder (123a) and a through hole (123b), the air can be adjusted in the direction desired by the user, thereby improving the ability to dry a specific area intensively.

[0140] The present invention includes a smart control function to maximize user convenience. Conventional hair dryers require manual button operation, and some wearable products also have the inconvenience of requiring the user to directly press a button attached to the main body to change the airflow and temperature. The present invention compensates for the shortcomings of existing products by adding an operation control unit (130) and a smartphone linkage function, allowing the user to remotely control the airflow, temperature, and spray direction of the hair dryer. Through this, the user can operate the hair dryer more intuitively and conveniently, and can dry hair under desired conditions without repetitive operation by applying preset preferred settings.

[0141] The present invention includes a structure for skin protection and improved comfort, thereby resolving the inconveniences of existing products. Conventional wearable hair dryers had the disadvantage of causing discomfort when worn for a long time, as heat could be transferred from the part that comes into direct contact with the user's skin. In the present invention, a material with excellent thermal insulation properties is applied to the skin contact surface (112) to prevent the user's skin from being exposed to direct heat, and a structure with breathability and cushioning is applied to maximize comfort when worn. Through this, the user can use the hair dryer without skin irritation or fatigue even when wearing it for a long time.

[0142] The present invention solves the problem of overheating in existing products by including an air heating unit (122) of an air flow unit (120) to precisely control the temperature of the air. Some conventional hair dryers had problems where the air exceeded a certain temperature, causing discomfort to the user or degrading the product's performance due to overheating. In the present invention, an overheating prevention function is added by applying a PTC heater, and by enabling the user to set the desired temperature in conjunction with a temperature control button (130c), a safer and more efficient hair drying environment can be provided.

[0143] The present invention solves the air circulation problem of existing products by optimizing the air intake fan (121) and the air flow path to smoothly regulate the airflow. In existing wearable hair dryers, the air intake port is fixed in a specific position, so if the user's hair or collar blocks the intake port, a problem may occur where the airflow is not smooth. In the present invention, the position of the air intake fan (121) is optimized, and a foreign matter prevention filter is applied to the intake port to prevent obstruction of air intake. Through this, the airflow can be continuously maintained smoothly, and more stable performance can be provided.

[0144] The present invention includes an individual group control function, allowing the user to selectively dry only specific areas. Conventional hair dryers make it difficult to dry specific areas intensively because air is sprayed evenly across the entire area. In this invention, a first group control unit (131), a second group control unit (132), and a third group control unit (133) are applied to enable individual control of drying for the back of the head, the left sideburns, and the right sideburns. Through this, the user can selectively direct airflow only to the desired areas, enabling more efficient hair styling and drying.

[0145] The above detailed description of the present invention describes only specific embodiments thereof. However, it should be understood that the present invention is not limited to the specific forms mentioned in the detailed description, but rather should be understood to include all variations, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims.

[0146] In other words, the present invention is not limited to the specific embodiments and descriptions described above, and any person skilled in the art to which the present invention pertains can make various modifications without departing from the essence of the invention as claimed in the claims, and such modifications fall within the scope of protection of the present invention.
