Description

Technical Field

[0001] This disclosure relates to a hair styling nozzle for fixing the shape of hair and a hair dryer including the hair styling nozzle. Background Technology

[0002] A hair dryer that vents air through an air outlet can be used to allow moisture from wet hair to flow back as desired or to shape hair from its current shape to a desired shape.

[0003] Fan units and other components for facilitating airflow can be embedded in the hair dryer, and hair dryers with such internal configurations can be designed to allow users to conveniently use the hair dryer, taking into account its own weight, etc.

[0004] When the heater module is located inside the head and the temperature of the housing also increases due to the heat from the heater module, there is a risk of burns, and internal components such as the controller may be affected. Therefore, a structure is needed in which the heat from the heater module is not transferred to the outside or other locations, but is instead transferred entirely to the air passing through the airflow path.

[0005] In particular, in order to use the hair dryer wirelessly, a battery needs to be embedded, space needs to be additionally ensured in the hair dryer for installing the battery, and components such as an ion generator can be additionally set up to expand functionality.

[0006] Hair dryers can be used for both drying and styling hair. However, achieving a truly satisfactory hairstyle often requires separate tools such as hairbrushes or heated straighteners, or professional skills, making it difficult to do so directly at home.

[0007] Various types of accessories are being developed to expand the functionality of hair dryers, making it easier to style hair even at home. Summary of the Invention

[0050] This disclosure relates to portable devices that can be used by hand, and more specifically, to small electronic devices designed for handheld use. Since the portable device is not used in a fixed position but is directly held and used by the user, it needs to be lightweight, and a comfortable grip on the handle 102 is important. Additionally, since the portable device is susceptible to contamination by external substances, waterproof features may be required. A seal is needed between the housing and the frame to prevent internal air from being released into areas other than the air vent.

[0051] The portable devices disclosed herein relate to beauty devices. For example, the portable device relates to a hair dryer 100. Although this disclosure is described based on a hair dryer 100, it is not limited thereto. Portable devices such as handheld skincare devices or body care devices may also be included within the scope of this disclosure.

[0052] Figure 1 This is a front perspective view of a hair dryer 100 according to an embodiment of the present disclosure. Figure 2 This is a rear perspective view of a hair dryer 100 according to an embodiment of the present disclosure. Figure 3 It is along Figure 2 The image above is a cross-sectional view of the hair dryer 100 according to an embodiment of the present disclosure, taken by line AA.

[0053] In the attached diagram, the x-axis represents the left-right direction, the y-axis represents the front-back direction, and the z-axis represents the up-down direction. When viewed from the front, +x represents the right side, and -x represents the left side. Furthermore, +y represents the forward direction, -y represents the backward direction, +z represents the upward direction, and -z represents the downward direction.

[0054] A hair dryer 100 according to an embodiment of the present disclosure includes a main body, which includes a head 101 and a handle portion 102. The handle portion 102 includes an air inlet 104 at its lower part through which air is introduced from the outside, and the head 101 includes an air outlet 103 through which air is discharged, a heater module 150, and a touch display 135 on its rear surface.

[0055] The interior of the main bodies 101 and 102 of the hair dryer 100 includes an airflow path extending from the air inlet 104 to the air outlet 103. The airflow path disclosed herein is not a straight path. Specifically, as... Figure 3 As shown, the air in the airflow path flows vertically in the handle portion 102 and then bends horizontally in the head 101.

[0056] Air inlet 104 may be located at the lower part of handle portion 102, and air outlet 103 may be located in front of head 101. Handle portion 102 and head 101 may have shapes corresponding to the direction of airflow path extension. For usability, handle portion 102 may extend in a direction slightly inclined forward relative to head 101 from the vertical direction.

[0057] The handle portion 102 can be formed into a cylindrical shape with a diameter that the user can grasp, and the head 101 can be formed into a cylindrical shape with a diameter larger than that of the handle portion 102. The diameter of the handle portion 102 can be uniform from bottom to top, but the head 101 can have a slightly smaller diameter at the front to guide air toward the air outlet 103.

[0058] The air inlet 104 may include an air intake hole 1283 formed around the periphery of the handle portion 102 and a filter for preventing the introduction of other foreign objects such as dust. A filter frame to which the filter is fixed may be located at the lower part of the handle portion 102 and may constitute the air inlet 104.

[0059] The filter is made of a different material than the housings 111 and 121 that form the exterior of the hair dryer 100, and is a thin-film component, thus it may be damaged by external impacts. Therefore, a filter cover 128 for protecting the filter may be further included, and the filter cover 128 may be configured to be removable to facilitate cleaning and replacement of the filter.

[0060] Air outlet 103 may be located in front of head 101 and may include an annular opening. For example... Figure 3 As illustrated, the heating wire 156 of the heater module 150 of this disclosure has a donut shape with a hollow center and is wound around a cylindrical heater housing 158. The air outlet 103 may also have an annular shape corresponding to the arrangement of the heating wire 156. That is, the center of the air outlet 103 can be blocked to form this annular shape.

[0061] The hair styling nozzle 200 may be further included and coupled to the air outlet 103 to expand the functionality of the hair dryer 100. The hair styling nozzle 200 can be easily detached via a magnet located at the center of the air outlet 103.

[0062] Figure 4 This is a front perspective view of the hair styling nozzle 200 according to the first embodiment of this disclosure, and Figure 5 This is a rear perspective view of a hair styling nozzle 200 according to a first embodiment of the present disclosure. The hair styling nozzle 200 of the present disclosure is used to press and fix the side hair above the ears in short hair styling. A styling method that guides the vertically protruding hair from the roots above the ears into close contact with the scalp is commonly referred to as press-down styling.

[0063] While perming products can be used to perform downward styling at a hair salon, there's a problem: after a certain period, the hair may stand up again due to new hair growth. A styling tool is needed that allows for easy styling at home while the hair is dry, without needing to visit a salon.

[0064] To prevent side hair from sticking out, conventional devices can be worn on the head in a band-like form. However, the back hair may be pressed down by the band connecting the two ends. Alternatively, band-like devices require prolonged use for pressing and styling, or pose a risk of burns when heat is applied.

[0065] This disclosure provides a hair styling nozzle 200 that can be connected to an air outlet 103 of a hair dryer 100, enabling pressure styling to be performed at home.

[0066] The hair dryer 100 disclosed herein may include: a rear coupling 210 located at the rear and fastened to an air outlet 103; and a nozzle head 220 located at the front and having nozzle holes 222, 223, and 224 (see [link to documentation]). Figure 7 The nozzle provides hot air through the nozzle orifice; and an air guide 230 is connected between the rear connection 210 and the nozzle head 220 and guides the hot air from the rear to the front.

[0067] like Figure 5 As illustrated, it may include a rear connection portion 210 having a shape corresponding to the air outlet 103 of the blower 100, and the rear connection portion 210 may include an annular connection portion 211 fastened to the outer periphery of the air outlet 103 and a central connection portion 215 fastened to the center of the air outlet 103.

[0068] The central connecting part 215 can be magnetically fastened to the nozzle connecting part 113 located at the center of the air outlet 103. A magnet with a polarity different from that of the nozzle connecting part 113 can be provided to fix the hair styling nozzle 200 to the main body head 101.

[0069] When the central connecting portion 215 and the nozzle connecting portion 113 are fixed by magnetic force, the annular connecting portion 211 is in close contact with the outer periphery of the air outlet 103. The rear surface of the annular connecting portion 211 may include an elastic material, such that the rear surface of the annular connecting portion 211 is in close contact with the air outlet 103 of the head 101 to prevent air leakage between the annular connecting portion 211 and the air outlet 103.

[0070] The nozzle head 220 located in front of the rear connector 210 may include a plurality of first nozzle holes 222 for uniformly supplying hot air introduced through the rear connector 210 to the hair.

[0071] The hair styling nozzle 200 disclosed herein is a device used to make close contact with the head above the ears, and the area of ​​the nozzle head 220 is larger than the area of ​​the rear connecting part 210, so that hot air can be supplied to a wide area.

[0072] The length of the nozzle head 220 in the horizontal direction can be greater than its length in the vertical direction, and it can have a rectangular shape or, for example, a rectangular shape. Figure 4 The example illustrates the shape of the curved corners.

[0073] Figure 6 This is a horizontal sectional view of the hair styling nozzle 200 according to the first embodiment of this disclosure, and is along... Figure 4 A sectional view taken by line BB. For example... Figure 6As illustrated, the nozzle head 220 can be bent to have a predetermined curvature in the horizontal direction corresponding to the shape of the head, such that both ends protrude in the forward direction. Since the length in the vertical direction is shorter than the length in the horizontal direction, and the head portion above the ears is not a portion with a large curvature, the nozzle head 220 can have a flat surface in the vertical direction.

[0074] The air guide 230 may include an outer guide 231 extending from the outer periphery of the annular connecting portion 211 and a phase plug 235 extending from the central connecting portion 215.

[0075] Because the nozzle head 220 is wider in the horizontal direction than the rear connecting portion 210, the outer guide 231 extending from the rear connecting portion 210 to the nozzle head 220 has a wider front end than its rear end. The outer guide 231 can have a shape that gradually widens from the rear connecting portion 210 to the nozzle head 220, but it can also be configured to have a shape that narrows from the rear end toward the front end and then widens again, such as... Figure 6 exemplified in .

[0076] Since the air outlet 103 has an annular shape, if the outer guide 231 does not have a portion (rear end) that collects air toward the center, hot air may not be smoothly supplied to the central portion. Therefore, the rear end of the outer guide 231 may have a shape that narrows toward the front.

[0077] The phase plug 235 can be formed with a gently curved surface that narrows from the rear to the front, corresponding to the shape of the rear end of the outer guide 231. Although the phase plug 235 in this embodiment is formed in a hemispherical shape, since the width in the horizontal direction of the nozzle head 220 is different from the width in the vertical direction of the nozzle head 220, the shape in the vertical direction and the shape in the horizontal direction of the phase plug 235 can be configured differently.

[0078] For a downward-pressing style that presses the hair above the ears down, the nozzle head 220 may include a plurality of vertical ribs 221 extending in the vertical direction, causing air discharged from the nozzle orifice 222 to flow downward. For example... Figure 6 As illustrated, vertical ribs 221 can protrude forward from the front surface 226 of the nozzle head 220, and multiple vertical ribs 221 can be arranged at predetermined intervals in the horizontal direction.

[0079] Figure 7 This is a vertical sectional view of the hair styling nozzle 200 according to the first embodiment of this disclosure, and is along... Figure 4The cross-sectional view is taken from line CC. Vertical ribs 221 protrude forward from the front surface 226 of the nozzle head 220, ensuring that the front surface 226 of the nozzle head 220 does not directly contact the scalp and can maintain a predetermined distance. Hot air supplied through the first nozzle orifice 222 to the space between the front surface 226 of the nozzle head 220 and the scalp can flow downwards because horizontal flow is restricted by the vertical ribs 221.

[0080] The front surface 226 of the nozzle head 220 of this disclosure is characterized by having multiple steps. (Refer to...) Figure 7 The front surfaces 2261, 2262 and 2263 are formed as three steps, but can be formed as two front surfaces 226 or more front surfaces 226.

[0081] The front surface 226 may include a first front surface 2261 located at the top and a second front surface 2262 located below the first front surface 2261 and in the rearward direction. A third front surface 2263 may be located below the second front surface 2262, or the front surface 226 may be formed by a greater number of front surfaces 226 forming multiple steps.

[0082] Due to the multi-step structure, the distance between the user's scalp and the front surfaces 2261, 2262, and 2263 of the nozzle head is greater at the bottom, so the heat emitted from the first nozzle orifice 222 can flow downwards.

[0083] Reference Figure 7 The front end of the vertical rib 221 forms a straight line extending in the vertical direction, but the rear end of the vertical rib 221 forms a step and can be located in the rearward direction. That is, since the front surfaces 2261, 2262 and 2263 of the nozzle head 220 are located in the rearward direction as they extend downward, the width of the vertical rib 221 in the front-rear direction can have a multi-step shape with the lower side wider than the upper side.

[0084] Multiple first nozzle holes 222 facing forward can be formed in the first front surface 2261. Air discharged from the first nozzle holes 222 toward the head in a direction perpendicular to the first front surface 2261 can flow downward along the vertical rib 221.

[0085] To provide downward-flowing hot air, a downward-facing second nozzle hole 223 can be formed in the step portion between the first front surface 2261 and the second front surface 2262 disposed behind the first front surface 2261. When a third front surface 2263 is additionally included below the second front surface 2262, a third nozzle hole 224 can be further provided in the step portion between the second front surface 2262 and the third front surface 2263. Since the second nozzle hole 223 and the third nozzle hole 224 have similar functions, the description will refer to the second nozzle hole 223.

[0086] Figure 8 and Figure 9 This is a view illustrating the airflow of the second nozzle orifice 223 of the hair styling nozzle 200 according to the present disclosure.

[0087] The lower end of the first front surface 2261 and the upper end of the second front surface 2262 are spaced apart to form a step, and a second nozzle orifice 223 may be formed in the step. The shape of the second nozzle orifice 223 may vary depending on the position of the lower end of the first front surface 2261 and the upper end of the second front surface 2262.

[0088] Figure 8 The embodiment illustrated herein is one in which the lower end of the first front surface 2261 and the upper end of the second front surface 2262 are located at the same height in the vertical direction (y1=0) and are arranged apart from each other only in the front-back direction (x>0).

[0089] In this respect, since the second nozzle orifice 223 faces downward in the vertical direction, the air discharged from the second nozzle orifice 223 also faces downward. However, in this case, the hot air may flow downward and be discharged before it is supplied to the hair, so the shape of the second nozzle orifice 223 can be changed so that the hot air is further supplied in the forward direction.

[0090] Figure 9 The embodiment illustrated herein is one in which the lower end of the first front surface 2261 and the upper end of the second front surface 2262 are positioned vertically spaced apart from each other (y2>0), and the nozzle orifice may have a shape that opens in an inclined direction toward the lower side of the front surface 226. Figure 9 The airflow in the figure illustrates the simulation results with a design of y2=2mm.

[0091] The air discharged from the second nozzle orifice 223 in this embodiment is compared to Figure 8 In this embodiment, the air is discharged at a more oblique angle, so hot air can reach a position further forward than the front end of the vertical rib 221, such as... Figure 9As illustrated in the example. Therefore, in this embodiment, hot air can be delivered more effectively to the hair located in front of the nozzle head 220.

[0092] The second nozzle orifice 223 can be configured such that its dimension in the front-rear direction is larger than its dimension in the vertical direction (x>y2), so that the hot air discharged through the second nozzle orifice 223 is discharged in a downward-sloping direction rather than in the forward direction. Since the dimensions of the second nozzle orifice in the front-rear direction and in the vertical direction are determined by the positions of the lower end of the first front surface 2261 and the upper end of the second front surface 2262, the distance between the lower end of the first front surface 2261 and the upper end of the second front surface 2262 can be configured such that the distance in the vertical direction is smaller than that in the front-rear direction.

[0093] The second nozzle orifice 223 can be configured such that its dimension in the front-rear direction is larger than its dimension in the vertical direction (x>y2), so that the hot air discharged through the second nozzle orifice 223 is discharged in a downward-sloping direction rather than in the forward direction. Since the dimensions of the second nozzle orifice in the front-rear direction and in the vertical direction are determined by the positions of the lower end of the first front surface 2261 and the upper end of the second front surface 2262, the distance between the lower end of the first front surface 2261 and the upper end of the second front surface 2262 can be configured such that the distance in the vertical direction is smaller than that in the front-rear direction.

[0094] Figure 10 This is a view illustrating the use of the hair styling nozzle 200 of this disclosure. Since the hair styling nozzle 200 of this disclosure is used in close contact with the portion above the ear, hot air flowing downwards along the vertical ribs 221 can be supplied to the ear E, such as... Figure 10 exemplified in .

[0095] The ear is a body organ that is particularly sensitive to temperature, and there is a problem of usability degradation when hot air is supplied directly to the ear E. To prevent heat from being supplied directly to the ear E, a lower guide 241 located below the vertical rib 221 may be further included.

[0096] Figure 11 This is a front perspective view of a hair styling nozzle 200 according to the second embodiment of the present disclosure, and illustrates the lower guide 241 located below the nozzle head 220 in this embodiment. Figure 12 This is a vertical cross-sectional view of a hair styling nozzle 200 according to a second embodiment of the present disclosure, illustrating the airflow in the hair styling nozzle 200.

[0097] like Figure 12As illustrated, the lower guide 241 may have a horizontal length corresponding to the horizontal width of the nozzle head 220, and may extend further rearward than the rear end of the vertical rib 221. Hot air flowing downward along the vertical rib 221 can be guided rearward by the lower guide 241.

[0098] However, in this embodiment, the lower guide 241 is positioned at a predetermined distance from the lower end of the vertical rib 221, and air can be supplied not only to the rear of the hair styling nozzle 200 but also to its front. Therefore, hot air may accumulate above the ear, and the temperature above the ear may rise.

[0099] To solve the above problem, the tilt angle of the lower guide 241 can be configured differently. Figure 13 This is a view illustrating the airflow in the hair styling nozzle 200 according to the third embodiment of this disclosure, and the lower guide 241 of this embodiment has a shape that is more rearwardly inclined than that of the above embodiment.

[0100] The downward flow path 243 formed by the lower guide 241 is wider in the rearward direction, so air can be directed in the rearward direction rather than the forward direction. The lower guide 241 can be configured to have an inclination of 5 degrees or more and 30 degrees or less.

[0101] Furthermore, the vertical rib 221 can extend to the lower guide 241, so that the air flowing downward along the vertical rib 221 can flow backward along the inclined direction of the lower guide 241 when it reaches the lower guide 241.

[0102] Figure 14 This is a view illustrating airflow in a hair styling nozzle 200 according to a first embodiment of the present disclosure. A vertical rib 221 is located above the lower guide 241 and may further include a lower recess 242 recessed from the rear to the front.

[0103] When the lower groove 242 is included, the space for air flowing downward along the vertical rib 221 to the rear end increases, and the amount of air flowing along the lower flow path 243 to the rear of the nozzle head 220 can increase.

[0104] Figure 15 This is a view illustrating airflow in a hair styling nozzle 200 according to a fourth embodiment of the present disclosure. This embodiment may include a windbreak rib 244 protruding in the forward direction of the lower guide 241 to block the airflow flowing in the forward direction.

[0105] The windbreak rib 244 can block the air flowing downward along the vertical rib 221 from flowing forward and increase the amount of air flowing backward along the lower guide 241.

[0106] Figure 16 This is a view illustrating the state in which the hair styling nozzle 200, according to the first embodiment of this disclosure, is attached to the main body head 101. (See attached image.) Figure 16 As illustrated, the main body of the hair dryer 100 has a cylindrical shape extending in the front-to-back direction, and includes a head 101 in which an air outlet 103 is positioned, and a handle portion 102 extending downward from the head 101 for the user to hold in their hand.

[0107] When hot air connected to the front of the hair styling nozzle 200 is supplied to the rear lower side of the hair styling nozzle 200 via the lower guide 241, this hot air is also supplied to the handle portion 102 of the main body, which may cause the hand holding the handle portion 102 to become hot. The hot air supplied to the handle portion 102 has a lower temperature than the hot air supplied directly to the lower part of the hair styling nozzle 200, but it still affects usability.

[0108] In this disclosure, a central guide 245 may be additionally provided on the lower guide 241, so that hot air flowing through the lower guide 241 toward the back of the hair styling nozzle 200 can be supplied while avoiding the handle.

[0109] Figure 17 This is a cross-sectional view of a hair styling nozzle 200 according to a first embodiment of the present disclosure. A center guide 245 is located between the lower end guide 241 and the lower portion of the nozzle head 220, and widens rearward from the lower rear surface of the central vertical rib 221. The center guide 245 may include a pair of inclined surfaces on the left and right sides, and may have a bilaterally symmetrical shape.

[0110] The center guide 245 is used to disperse the hot air flowing backward along the lower guide 241 in the left and right directions, and to guide the hot air to flow while avoiding the user's hand holding the handle.

[0111] Although Figure 17 The center guide 245 is illustrated as having a straight incline, but the center guide 245 may include a curved surface projecting in a rearward direction to direct airflow outward.

[0112] Figure 18 This is a view illustrating the airflow of the hair styling nozzle 200 according to the present disclosure with or without the center guide 245. In (a), when the center guide 245 is not provided, the air flows in a straight line in the rearward direction and is delivered to the user's hand H holding the handle portion 102.

[0113] However, when the center guide 245 is arranged as in (b), the air in the center portion flows along the center guide 245 in the left-right direction of the nozzle head, thereby reducing the amount of hot air transmitted to the handle portion 102.

[0114] Figures 19 to 21 This is a view illustrating the airflow of the hair styling nozzle 200 according to the dimensions of the central guide 245.

[0115] Figure 19 Examples along Figure 16 The airflow in the cross section intercepted by the line EE. Figure 19 Examples of airflow are shown in (a) when the rear end width of the center guide 245 is 20 mm, in (b) when the rear end width is 30.6 mm, and in (c) when the rear end width is 40 mm, where (a) is the narrowest case and (c) is the widest case. It can be confirmed that as the rear end width increases, the amount of hot air supplied to the handle decreases.

[0116] Figure 20 An example is shown at a position approximately 15 mm from the center along... Figure 16 The airflow in the cross section intercepted by the line FF, and Figure 21 An example is shown at a position approximately 25 mm from the center along... Figure 16 The airflow in the cross section cut by line GG.

[0117] Reference Figure 20 When the width of the center guide 245 is narrow (a), air is discharged at the FF section. However, when the width of the center guide 245 is wide (c), air is guided by the center guide 245 to a more lateral position than the FF position, and the air discharged in the rearward direction is not detected.

[0118] Reference Figure 21 Even in embodiment (b) where the rear end width of the central guide 245 is 30.6 mm, air discharged behind the lower flow path 243 is detected in the GG section. However, when the rear end width of the central guide 245 is 40 mm or greater, as illustrated in (c), no rearward air discharge is detected in the GG section.

[0119] from Figures 19 to 21 It can be seen that as the width of the center guide 245 increases, the amount of air flowing towards the handle can be reduced. However, as the rear width of the center guide 245 increases, the size of the flow path discharged behind the lower flow path 243 decreases, which may instead interfere with the rearward airflow. Therefore, the rear width can be determined to be in the range of 30 mm or more and 65 mm or less.

[0120] This simulation is based on the assumption that the size of the nozzle head 220 is approximately 100 mm, and the size of the center guide 245 can vary depending on the size of the nozzle head 220.

[0121] When expressed in angle, the center guide 245 can form the inclined surfaces in such a way that the angle between the pair of inclined surfaces is in the range of 120 degrees or greater and 160 degrees or less.

[0122] Since the central guide 245 is located above the lower guide 241, when the lower guide 241 has a downwardly inclined surface as described in the above embodiment, the height of the lower guide 241 can also be increased rearward.

[0123] As described above, the hair styling nozzle 200 of this disclosure can guide air downwards, thereby effectively achieving styling that ensures close contact between the hair and the scalp.

[0124] In addition, the hair styling nozzle 200 disclosed herein can prevent hot air from being applied directly to the ears, thereby preventing burns caused by hot air.

[0125] Furthermore, in the hair styling nozzle 200 disclosed herein, hot air is not transferred to the hand holding the handle, thereby improving usability.
