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 for installing the battery needs to be additionally ensured in the hair dryer, and components such as an ion generator can be added to expand functionality.

[0006] Hair dryers can be used for both drying and styling hair. However, styling hair usually requires separate tools such as hairbrushes or hot straighteners, or professional skills, making it difficult to achieve highly satisfactory results 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

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] Air outlet 103 may be located in front of head 101 and may include an annular opening. For example... Figure 3As 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] like Figure 5As 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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 shape of the corner is shown in the example.

[0070] 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 6 As 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.

[0071] 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.

[0072] 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 .

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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 4 The 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.

[0077] 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.

[0078] 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.

[0079] Due to the multi-step structure, the gap between the user's scalp and the front surfaces 2261, 2262, and 2263 of the nozzle head is larger at the bottom, so the heat emitted from the first nozzle hole 222 can flow downward.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] Figure 8The 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).

[0086] 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.

[0087] 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.

[0088] 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 9 As 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.

[0089] 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.

[0090] Figure 10 This is a horizontal cross-sectional view of a hair styling nozzle 200 according to a second embodiment of the present disclosure. The hair styling nozzle 200 of the present disclosure is used in close contact with the user's scalp and may include an elastic member 262 such that when the user presses the hair styling nozzle 200 toward the scalp, the hair styling nozzle 200 can contact the scalp without applying additional pressure.

[0091] Methods such as adding rubber material to the protrusions that contact the scalp can be used. However, since the hair styling nozzle 200 of this disclosure contacts the scalp over a large area, hair may get stuck when the vertical ribs 221 that contact the scalp are formed of rubber.

[0092] Therefore, this disclosure can improve usability by adding elasticity to the fastening structure 260 between the nozzle head 220 and the air guide 230, so that the position of the nozzle head 220 in contact with the scalp can be variable.

[0093] In this embodiment, the fastening between the nozzle head 220 and the air guide 230 is achieved by an elastic fastening part 260, and the elastic fastening part 260 may include a spring 262, such as Figure 10 As illustrated in the example. Although the maximum distance between the air guide 230 and the nozzle head 220 is fixed, when the nozzle head 220 is pressed backward, the nozzle head 220 can be pushed backward, thereby reducing the distance between the nozzle head 220 and the air guide 230.

[0094] As described above, the air guide 230 may include a centrally located phase plug 235 and an outer guide 231 located around the periphery. The outer guide 231 extends from the annular connection 211 and provides a flow path for hot air discharged from the air outlet 103 to be supplied to the nozzle head 220.

[0095] Phase plug 235 protrudes forward from central connector 215 and may have a tapered shape in the forward direction. Phase plug 235 can be used to collect hot air discharged from annular air outlet 103 toward the center.

[0096] The elastic fastener 260 may include a spring 262 for changing the distance between the nozzle head 220 and the air guide 230, and a screw 261 for limiting the movement of the nozzle head 220 caused by the spring 262.

[0097] Screw 261 is a component that limits the maximum distance so that the nozzle head 220 and the air guide 230 do not separate from each other, and can pass through the phase plug 235 and be fastened to the screw boss 228 formed in the nozzle head 220.

[0098] The screw boss 228 protrudes rearward from the front surface 226 of the nozzle head 220 and can be formed on the second front surface 2262, since the second front surface 2262 does not have a nozzle hole facing forward.

[0099] The screw 261 inserted into the phase plug 235 is not fixed to the position of the phase plug 235 in the front-to-back direction, so the relative position of the phase plug 235 with respect to the screw 261 can be variable. The spring 262 can surround the outer surface of the screw 261 and can be inserted between the phase plug 235 and the nozzle head 220.

[0100] The spring 262 can adjust the gap between the nozzle head 220 and the air guide 230 while its length changes. Because the phase plug 235 has a curved surface, the portion through which the screw passes can protrude in the forward direction to form a protrusion 236, so that the rear end of the spring 262 can be supported.

[0101] Figure 10 This is a horizontal sectional view of the central portion in the vertical direction. (Refer to...) Figure 10 The nozzle head 220 may include a sidewall portion 225 extending rearward from the periphery of the front surface 226. An air guide 230 is inserted into the rear surface of the nozzle head 220, and the end of the outer guide 231 may be coupled to the inside of the sidewall portion 225 of the nozzle head 220.

[0102] Since the outer guide 231 is inserted from the rear of the nozzle head 220, the connection between the outer guide 231 and the nozzle head 220 faces rearward. The connection between the outer guide 231 and the nozzle head 220 is spaced apart from the front surface 226 of the nozzle head 220 that contacts the hair, thus minimizing the problem of hair getting stuck between the outer guide 231 and the nozzle head 220.

[0103] The nozzle head 220 may include a nozzle hook 229 protruding from the rear end of the sidewall portion 225, and the nozzle hook 229 may be fastened to the periphery of the outer guide 231 to retain the outer guide 231 so that the outer guide 231 does not separate from the nozzle head 220.

[0104] Because the nozzle catch 229 is engaged in the rearward direction of the outer guide 231, therefore... Figure 10 In the illustrated state, the nozzle head 220 moves in the rearward direction and does not restrict the movement of the outer guide 231 further into the nozzle head 220. In addition to the nozzle catch 229 protruding from the end of the side wall portion 225 of the nozzle head 220, a catch 229' for preventing separation between the air guide 230 and the nozzle head 220 may be further included.

[0105] Because the nozzle head 220 has a movable structure, a nozzle catch 229 is required to prevent interference between the nozzle head 220 and the air guide 230. However, air introduced into the hair styling nozzle 200 through the movement gap g may leak through this gap. A sealing ring 250 may be included to allow movement between the nozzle head 220 and the air guide 230 while simultaneously blocking air leakage through the movement gap g between the nozzle head 220 and the air guide 230.

[0106] The sealing ring 250 can be inserted between the periphery of the outer guide 231 and the periphery of the side wall portion 225 of the nozzle head 220, and can have an annular shape with both ends connected. Unlike typical sealing structures used for waterproofing or windproofing purposes, the sealing ring 250 of this disclosure needs to prevent air leakage while being flexible, and is therefore characterized by its cross-sectional shape.

[0107] Figure 11 This is a cross-sectional view illustrating the sealing ring 250 of the hair styling nozzle 200 according to the second embodiment of the present disclosure.

[0108] The sealing ring 250 can be fixed to the periphery of the outer guide 231 to face outwards and can contact the inner side of the sidewall portion 225 of the nozzle head 220. The sealing ring 250 can be configured to be larger than the gap between the nozzle head 220 and the outer guide 231 so as to make tight contact with the nozzle head 220.

[0109] The sealing ring 250 may include a fixing portion 251 fixed to the outer guide 231, and a contact portion 254 in close contact with the side wall portion 225 of the nozzle head 220. A flexible portion 252 that can easily change shape according to the movement of the nozzle head 220 may be included between the contact portion 254 and the fixing portion 251.

[0110] The sealing ring 250 may include an elastic material such as silicone resin, and the fixing portion 251, the contact portion 254, and the flexible portion 252 may be made of the same material or may be made of different materials. However, for ease of manufacture, the fixing portion 251, the contact portion 254, and the flexible portion 252 may be made of the same material, but may be configured to have different properties by changing their thickness and shape.

[0111] The contact portion 254 is elastic and can be in close contact with the sidewall portion 225 of the nozzle head 220, and can be configured to have a large area so as to maintain contact with the sidewall portion 225 of the nozzle head 220 even during movement.

[0112] Figure 12This is a cross-sectional view illustrating various embodiments of the sealing ring 250 of the hair styling nozzle 200 according to a second embodiment of the present disclosure. The contact portion 254 may have, for example... Figure 12 The semi-circular cross section illustrated in (a) can be formed as follows: Figure 12 The rectangular shape illustrated in (b) is an example. Protrusions 255, wrinkles, etc., may be formed at the end of the contact portion 254 (i.e., at the part of the contact sidewall portion 225).

[0113] The contact portion 254 of the sealing ring 250 can be formed as a tubular shape with an empty internal space so as to make close contact with the sidewall portion 225 when it contacts the sidewall portion 225. Since the sealing ring 250 forms a closed curve, the inner surface (right side in the figure) connected to the outer guide 231 can be opened like a bicycle inner tube to form an empty space inside the contact portion 254.

[0114] The flexible part 252 can be made of a material that can easily change shape, and the movement caused by the movement of the nozzle head 220 can be counteracted by the deformation of the flexible part 252, thereby minimizing the movement of the contact part 254 on the side wall part 225.

[0115] like Figure 11 As illustrated, wrinkles can be formed in the flexible portion 252, making it easy to change shape. The flexible portion 252 can be configured to have a thickness equal to or less than the thickness of the contact portion 254.

[0116] The fixing portion 251 is rigid to ensure stable fixation to the outer guide 231 and can be formed thicker than other portions to ensure rigidity. However, due to the risk of separation caused by material properties, fixing ribs 2341 and 2342 may be included for securing the sealing ring 250 to the outer guide 231, such as... Figure 11 exemplified in .

[0117] The fixing rib may include a first fixing rib 2341 that surrounds not only the outer side of the fixing part 251 but also the inner side, the front surface 226 and the rear surface, and may include a second fixing rib 2342 that surrounds not only the fixing part 251 but is inserted into the center of the fixing part 251.

[0118] Because the sealing ring 250 has an inner opening, the fixing portion 251 is divided into a front portion and a rear portion, so the second fixing rib 2342 can be inserted between the separated portions of the fixing portion 251. The second fixing rib 2342 can be formed in a T-shape to minimize the separation of the sealing ring 250.

[0119] The wall thickness of the contact portion 254 can be configured to be 0.5 mm or less, and the wall thickness of the fixing portion 251 can be configured to be 1 mm or more, such that the wall thickness of the fixing portion 251 is several times that of the wall thickness of the contact portion 254. In this embodiment, the wall thickness of the contact portion 254 is 0.3 mm, and the wall thickness of the fixing portion 251 is 1.5 mm.

[0120] As described above, the hair styling nozzle 200 of this disclosure can effectively achieve styling by guiding air to flow in a downward direction, thus ensuring close contact between the hair and the scalp.

[0121] Furthermore, the hair styling nozzle disclosed herein can softly contact the scalp through the movable structure of the nozzle head 220, thereby improving usability.

[0122] Furthermore, the hair styling nozzle disclosed herein can prevent air leakage through the movement gap g between the nozzle head 220 and the air guide 230.

[0123] Although this disclosure has been illustrated and described with reference to specific embodiments, it will be apparent to those skilled in the art that various modifications and alterations can be made to this disclosure without departing from the technical spirit of the disclosure as provided by the appended claims.
