Description

Hair styling nozzle and hair dryer

[0001] The present invention relates to a hair styling nozzle for fixing the shape of hair and a hair dryer having the same.

[0002] A hair dryer that discharges gas through an air outlet can be used to remove as much moisture as desired from wet hair or to style hair from its current shape to a desired shape.

[0003] A fan unit for circulating gas may be built into the inside of the hair dryer, and a hair dryer including such an internal configuration may be designed to be convenient for the user to use by taking into account its own weight, etc.

[0004] The heater module is located in the head, and if the heat from the heater module increases the case temperature, it poses a risk of burns and can affect internal components such as the control unit. Therefore, a structure is required that ensures that the heat from the heater module is fully transferred to the air passing through the circuit, rather than being transferred to the outside or other sources.

[0005] In particular, for wireless use, a battery must be built-in, additional space must be secured for mounting the battery in the hair dryer, and additional components such as an ion generator can be installed to expand functionality.

[0006] Hair dryers can be used for more than just drying hair. Styling hair requires separate tools like hairbrushes or heat-applying curling irons, or professional techniques, making it difficult to achieve satisfactory results at home.

[0007] Development is underway on various types of accessories to expand the functionality of hair dryers, making hair styling easier even at home.

[0008] The purpose of the present invention is to provide a hair styling nozzle and a hair dryer equipped with the nozzle, which can easily perform down perm styling at home by bringing hair above the ears into close contact with the scalp.

[0009] A hair styling nozzle coupled to an air discharge unit of a hair dryer, comprising: a rear coupling portion coupled to the air discharge unit; an air guide extending forward from the rear coupling portion; a nozzle head positioned in front of the air guide and including a nozzle hole through which wind is discharged; a lower guide positioned a predetermined distance from a lower end of the nozzle head and guiding wind discharged from the nozzle hole to the rear; and a central guide positioned between the lower guide and the nozzle head and widening in a rearward direction.

[0010] The above central guide is located at the horizontal center of the nozzle head and can be symmetrical left and right.

[0011] The central guide includes a pair of inclined surfaces extending horizontally from the center toward the rear surface, and an angle between the pair of inclined surfaces may have a value of 120° or more and 160° or less.

[0012] The above central guide has a horizontal width of the rear end of 30 mm or more, and may be smaller than the width of the above lower guide.

[0013] The above lower guide extends toward the back surface forming a downwardly inclined slope, and the above central guide may become longer in vertical length toward the rear end.

[0014] The above nozzle head may include a nozzle hole through which wind discharged from the air discharge unit is discharged; and a plurality of vertical ribs that protrude forward from the front and extend vertically to guide wind discharged from the nozzle hole downward.

[0015] The front end of the above central guide can extend from the lower rear surface of the above vertical rib.

[0016] A hair dryer is provided, comprising: a main body of a hair dryer including a ring-shaped air discharge portion; and a hair styling nozzle coupled to the air discharge portion, wherein the hair styling nozzle comprises: a rear coupling portion coupled to the air discharge portion; an air guide extending forward from the rear coupling portion; a nozzle head positioned in front of the air guide and including a nozzle hole through which wind is discharged; a lower guide positioned a predetermined distance from a lower end of the nozzle head and guiding wind discharged from the nozzle hole rearward; and a central guide positioned between the lower guide and the nozzle head and widening in a rearward direction.

[0017] The hair styling nozzle of the present invention can effectively implement a style in which hair is closely attached to the scalp by guiding the wind to flow downward.

[0018] In addition, the hair styling nozzle of the present invention can prevent burns caused by hot air by preventing hot air from being directly applied to the ears.

[0019] In addition, the hair styling nozzle of the present invention can improve usability because hot air is not transmitted to the hand holding the handle.

[0020] The effects that can be obtained from the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by a person having ordinary skill in the art to which the present invention belongs from the description below.

[0043] Additionally, the terms used herein are only used to describe specific embodiments and are not intended to limit the present invention.

[0044] Also, in this specification, singular expressions may include plural expressions unless the context clearly indicates otherwise.

[0045] In addition, in this specification, it should be understood that terms such as “include” or “have” are intended to specify only the presence of a feature, number, step, operation, component, part, or combination thereof described in the specification, and do not exclude in advance the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0046] Also, in this specification, the term 'and / or' includes a combination of multiple listed items or any one of multiple listed items. In this specification, 'A or B' can include 'A', 'B', or 'both A and B'.

[0047] The present invention relates to a portable device that can be held and used by a user, and refers to a small-sized electronic device that a user can hold and use by hand. Since the portable device is not used in a stationary state but is directly held by the user, it must be lightweight, and the grip of the handle (102) is important. In addition, a waterproof function may be required to prevent external contaminants from entering. Furthermore, the gap between the case and the frame needs to be sealed to prevent internal air from being discharged to areas other than the air outlet.

[0048] The portable device of the present invention relates to a beauty device, and a representative example thereof is a hair dryer (100) for managing hair. Although the description is based on the hair dryer (100), the present invention is not limited thereto, and portable devices such as skin care devices or body care devices that a user holds in his / her hand and uses may also be included in the present invention.

[0049] Fig. 1 is a front perspective view illustrating a hair dryer (100) according to one embodiment of the present invention, and Fig. 2 is a rear perspective view of the hair dryer (100) according to one embodiment of the present invention. Fig. 3 is a cross-sectional view of the hair dryer (100) according to one embodiment of the present invention, taken along line AA of Fig. 2.

[0050] In the drawing, 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 is the right, and -x is the left. +y is the front, -y is the back, +z is the top, and -z is the bottom.

[0051] A hair dryer (100) according to one embodiment of the present invention includes a main body composed of a head portion (101) and a handle portion (102). The handle portion (102) is provided with an air inlet portion (104) at the bottom through which air is introduced from the outside, and the head portion (101) may include an air discharge portion (103) through which gas is discharged, a heater module (150), and a touch display (135) on the back.

[0052] The interior of the main body (101, 102) of the hair dryer (100) includes an air path extending from the air inlet (104) to the air outlet (103). The air path of the present invention is not a straight path, but moves vertically from the handle portion (102) and then bends horizontally from the head portion (101), as shown in FIG. 3.

[0053] The air inlet (104) may be located at the bottom of the handle (102), and the air outlet (103) may be located at the front of the head (101). The handle (102) and the head (101) have shapes corresponding to the extension direction of the air flow path. For usability, the handle (102) may extend in a direction slightly inclined forward from the vertical direction based on the head (101).

[0054] The handle portion (102) is configured as a cylinder with a diameter that a user can hold by hand, and the head portion (101) can also be configured as a cylinder with a larger diameter than the handle portion (102). The diameter of the handle portion (102) can be formed to be the same from the bottom to the top, but the head portion (101) can have a shape with a slightly smaller diameter at the front so that wind comes out at a high speed with strong pressure through the air discharge portion (103).

[0055] The air inlet (104) includes a gas intake hole (1283) formed along the periphery of the handle portion (102) and may include a filter to prevent foreign substances such as dust from entering. A filter frame to which the filter is fixed may be positioned at the bottom of the handle portion (102) and may constitute the air inlet (104).

[0056] The filter is made of a different material from the case (111, 121) forming the exterior of the hair dryer (100), and is a thin film-shaped member, so it may be damaged by external impact. Therefore, a filter cover (128) may be further included to protect the filter, and the filter cover (128) may be configured to be detachable for cleaning and replacement of the filter.

[0057] The air discharge unit (103) is located in front of the head unit (101) and may include a ring-shaped opening. As illustrated in FIG. 3, the heating wire (156) of the heater module (150) of the present invention has a donut shape with an empty center and is wound around a cylindrical heater housing (158). Depending on the arrangement of the heating wire (256), the air discharge unit (103) may also have a ring shape. That is, the center of the air discharge unit (103) may be blocked to form a ring shape.

[0058] In order to expand the functionality of the hair dryer (100), a hair styling nozzle (200) that is coupled to the air outlet (103) may be further included. The hair styling nozzle (200) may be easily detachable through a magnet located at the center of the air outlet (103).

[0059] Fig. 4 is a front perspective view of a hair styling nozzle (200) according to a first embodiment of the present invention, and Fig. 5 is a rear perspective view of a hair styling nozzle (200) according to the first embodiment of the present invention. The hair styling nozzle (200) of the present invention is a hair styling nozzle (200) for pressing and fixing the side hair above the ear in a short hairstyle. A styling method that presses the hair extending vertically from the hair root above the ear toward the scalp is commonly called down perm styling.

[0060] Down perms can be styled using perm products at a salon, but after a certain period of time, new hair growth causes them to re-grow. There is a need for styling tools that allow for easy styling at home while drying hair, without having to visit a salon.

[0061] Traditionally, band-style hair clips have been used to prevent hair from sticking out at the sides. However, these can cause the hair at the back to become squished by the band connecting the two ends. Furthermore, band-style devices pose a risk of burns when used for long periods of time for down perm styling or when exposed to heat.

[0062] The present invention provides a hair styling nozzle (200) that can be connected to an air outlet (103) of a hair dryer (100) to enable down perm styling at home.

[0063] The hair dryer (100) of the present invention may include a rear coupling portion (210) located at the rear and connected to an air discharge portion (103), a nozzle head (220) located at the front and having nozzle holes (222, 223, 224, see FIG. 7) through which hot air is supplied, and an air guide (230) that guides hot air to be supplied from the rear to the front by connecting the rear coupling portion (210) and the nozzle head (220).

[0064] As shown in FIG. 5, the hair dryer (100) may include a rear coupling portion (210) having a shape corresponding to the air discharge portion (103), and the rear coupling portion (210) may include a ring coupling portion (211) that is fastened to the outer circumference of the air discharge portion (103) and a central coupling portion (215) that is fastened to the center of the air discharge portion (103).

[0065] The central joint (215) can be magnetically connected to the nozzle joint (210) located at the center of the air discharge unit (103). A magnet having a different pole from that of the nozzle joint (113) can be placed to secure the hair styling nozzle (200) to the main body head (101).

[0066] When the central joint (215) and the nozzle joint (113) are fixed by magnetic force, the ring joint (211) is in close contact with the outer circumference of the air discharge unit (103). To prevent air from leaking between the ring joint (211) and the air discharge unit (103), the back surface of the ring joint (211) may include an elastic material so as to be in close contact with the air discharge unit (103) of the head unit (101).

[0067] The nozzle head (220) located at the front of the rear coupling part (210) may include a plurality of first nozzle holes (222) for evenly supplying hot air introduced through the rear coupling part (210) to the hair.

[0068] The hair styling nozzle (200) of the present invention is a device that is used by being in close contact with the head above the ear, and the area of ​​the nozzle head (220) is wider than that of the rear joint (210) so that hot air can be supplied to a wide area.

[0069] The nozzle head (220) may have a horizontal length longer than a vertical length, and may be rectangular or have a curved corner as shown in FIG. 4.

[0070] Fig. 6 is a horizontal cross-sectional view of a hair styling nozzle (200) according to a first embodiment of the present invention, and is a BB cross-sectional view of Fig. 4. As illustrated in Fig. 6, the nozzle head (220) can be bent to have a predetermined curvature in the horizontal direction and both ends protrude forward, corresponding to the shape of the head. In the vertical direction, the length is shorter than the horizontal direction, and the head above the ear does not have a large curvature, so it can have a flat surface.

[0071] The air guide (230) may include an outer guide (231) extending from the outer periphery of the ring joint (211) and a phase plug (235) extending from the central joint (215).

[0072] Since the nozzle head (220) is wider horizontally than the rear joint (210), the outer guide (231) extending from the rear joint (210) to the nozzle head (220) is wider at the front end than at the rear end. The outer guide (231) may be configured to gradually widen from the rear joint (210) to the nozzle head (220), but as illustrated in FIG. 6, it may also be configured to narrow from the rear end to the front end and then widen again.

[0073] Since the air outlet (103) has a ring shape, if the outer guide (231) does not have a part (rear end) that gathers the wind toward the center, the supply of hot air to the center is not smooth, so the outer guide (231) may have a shape in which the rear end becomes narrower as it goes forward.

[0074] The phase plug (235) may have a gentle curve that becomes narrower from the rear to the front, corresponding to the shape of the rear end of the outer guide (231). The phase plug (235) of the present embodiment is configured in a hemispherical shape, but since the horizontal width and the vertical width of the nozzle head (220) are different, the vertical shape and the horizontal shape of the phase plug (235) may be configured differently.

[0075] For down perm styling that presses the hair above the ears downward, the nozzle head (220) may include a plurality of vertical ribs (221) extending vertically so that the wind ejected from the nozzle hole (222) flows downward. As illustrated in FIG. 6, the vertical ribs (221) may protrude forward from the front surface (226) of the nozzle head (220) and may be arranged in plurality at predetermined intervals in the horizontal direction.

[0076] Fig. 7 is a vertical cross-sectional view of a hair styling nozzle (200) according to a first embodiment of the present invention, which is a CC cross-sectional view of Fig. 4. The vertical rib (221) protrudes forward from the front surface (226) of the nozzle head (220) so that the front surface (226) of the nozzle head (220) does not directly contact the scalp and can maintain a predetermined distance therefrom. The hot air provided to the space between the front surface (226) of the nozzle head (220) and the scalp through the first nozzle hole (222) can flow downward because the horizontal flow is restricted by the vertical rib (221).

[0077] The front surface (226) of the nozzle head (220) of the present invention is characterized by being multi-staged. Referring to Fig. 7, the front surface (2261, 2262, 2263) is composed of three stages, but may be composed of two or more front surfaces (226).

[0078] The front (226) may include a first front (2261) located at the top and a second front (2262) located below the first front (2261) and in the rear direction. A third front (2263) or a plurality of fronts (226) formed in multiple stages may be configured below the second front (2262).

[0079] Due to the multi-stage structure, the gap between the user's scalp and the front of the nozzle head (2261, 2262, 2263) is wider at the bottom, allowing the heat emitted from the first nozzle hole (222) to move downward.

[0080] Referring to Fig. 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 positioned in the rear direction. That is, since the front (2261, 2262, 2263) of the nozzle head (220) is positioned in the rear direction as it goes downward, the width of the vertical rib (221) in the front-back direction can have a multi-stage form in which the lower side is wider than the upper side.

[0081] A plurality of first nozzle holes (222) facing forward may be formed on the first front surface (2261). Wind ejected vertically from the first nozzle holes (222) toward the head on the first front surface (2261) may move downward along the vertical rib (221).

[0082] In order to provide downwardly flowing hot air, a second nozzle hole (223) facing downwards may be formed in the step portion between the second front surface (2262) introduced rearward from the first front surface (2261). If a third front surface (2263) is additionally included below the second front surface (2262), a third nozzle hole (224) may 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 be based on the second nozzle hole (223).

[0083] Figures 8 and 9 are drawings showing the flow of wind according to the size of the second exposure hole (223) of the hair styling nozzle (200) of the present invention.

[0084] The lower part of the first front (2261) and the upper part of the second front (2262) are spaced apart to form a step, and a second nozzle hole (223) can be formed in the step. The shape of the second nozzle hole (223) can vary depending on the position of the lower part of the first front (2261) and the upper part of the second front (2262).

[0085] The embodiment illustrated in Fig. 8 is an embodiment in which the lower part of the first front surface (2261) and the upper part of the second front surface (2262) are positioned at the same height in the vertical direction (y1=0) and are spaced apart only in the front-back direction (x>0).

[0086] At this time, since the second nozzle hole (223) faces downward in a vertical direction, the direction of the wind discharged from the second nozzle hole (223) also faces downward. However, in this case, since the hot air can flow downward and be discharged before being provided to the hair, the shape of the second nozzle hole (223) can be changed so that the hot air is provided more forward.

[0087] The embodiment illustrated in Fig. 9 may have a shape in which the lower part of the first front surface (2261) and the upper part of the second front surface (2262) are vertically spaced apart (y2>0) and the nozzle hole is opened in an oblique direction toward the lower part of the front surface (226). The wind flow in Fig. 9 is designed with y2=2mm and shows the results of a simulation.

[0088] The wind discharged from the second nozzle hole (223) of the present embodiment is discharged obliquely compared to the embodiment of FIG. 8, so that the hot air can reach further forward than the front end of the vertical rib (221), as shown in FIG. 9. Therefore, in the present embodiment, the hot air can be more effectively transmitted to the hair located in front of the nozzle head (220).

[0089] The size of the second nozzle hole (223) in the front-back direction can be formed to be larger than the size in the vertical direction so that the hot air discharged through the second nozzle hole (223) is discharged in a direction inclined downward rather than forward (x>y2). Since the size of the second nozzle hole in the front-back direction and the size in the vertical direction are determined by the positions of the lower end of the first front part (2261) and the upper end of the second front part (2262), the gap between the lower end of the first front part (2261) and the upper end of the second front part (2262) can be formed to be smaller in the vertical direction than in the front-back direction.

[0090] The size of the second nozzle hole (223) in the front-back direction can be formed to be larger than the size in the vertical direction so that the hot air discharged through the second nozzle hole (223) is discharged in a direction inclined downward rather than forward (x>y2). Since the size of the second nozzle hole in the front-back direction and the size in the vertical direction are determined by the positions of the lower end of the first front part (2261) and the upper end of the second front part (2262), the gap between the lower end of the first front part (2261) and the upper end of the second front part (2262) can be formed to be smaller in the vertical direction than in the front-back direction.

[0091] Fig. 10 is a drawing illustrating a usage mode of the hair styling nozzle (200) of the present invention. Since the hair styling nozzle (200) of the present invention is used in close contact with the upper part of the ear, hot air moving downward along the vertical rib (221) can be supplied to the ear (E) as illustrated in Fig. 10.

[0092] The ear is a body organ that is particularly sensitive to temperature, and there is a problem that usability is hindered when hot air is directly supplied to the ear (E). To prevent heat from being directly supplied to the ear (E), a lower guide (241) located at the lower portion of the vertical rib (221) may be further included.

[0093] Fig. 11 is a front perspective view of a hair styling nozzle (200) according to a second embodiment of the present invention, which illustrates a lower guide (241) positioned at the bottom of a nozzle head (220). Fig. 12 is a vertical cross-sectional view of a hair styling nozzle (200) according to a second embodiment of the present invention, which illustrates the flow of wind in the hair styling nozzle (200).

[0094] As illustrated in Fig. 12, the lower guide (241) may have a horizontal length corresponding to the horizontal width of the nozzle head (220) and may extend further in the rearward direction than the rear end of the vertical rib (221). Hot air moving downward along the vertical rib (221) may be guided backward by the lower guide (241).

[0095] However, the lower guide (241) of the present embodiment is positioned a predetermined distance from the lower end of the vertical rib (221), and wind can be supplied not only to the rear but also to the front of the hair styling nozzle (200). Therefore, hot air can gather above the ears, and the temperature above the ears can rise.

[0096] To solve the above problem, the inclination of the lower guide (241) can be changed. Fig. 13 is a drawing illustrating the wind flow of the hair styling nozzle (200) according to the third embodiment of the present invention, and the lower guide (241) of this embodiment has a shape that is inclined in the rearward direction compared to the embodiment described above.

[0097] The lower channel (243) formed by the lower guide (241) is wider in the rear direction, so that wind can be guided backwards rather than forwards. The inclination of the lower guide (241) can be configured to be 5° or more and 30° or less.

[0098] In addition, by extending the vertical rib (221) to the lower guide (241), the wind that moves downward along the vertical rib (221) can move backward along the inclined direction of the lower guide (241) when it reaches the lower guide (241).

[0099] Fig. 14 is a drawing illustrating the wind flow of a hair styling nozzle (200) according to the first embodiment of the present invention. The vertical rib (221) is located above the lower guide (241) and may further include a lower groove (242) that is introduced from the rear to the front.

[0100] When the lower groove (242) is included, the space in which the wind that has moved downward along the vertical rib (221) can move to the rear end is expanded, so that the amount of wind moving to the rear of the nozzle head (220) along the lower flow path (243) can increase.

[0101] Fig. 15 is a drawing illustrating the wind flow of a hair styling nozzle (200) according to a fourth embodiment of the present invention. This embodiment may include a windbreak rib (244) protruding upwardly in front of the lower guide (241) to block the wind flow flowing forward.

[0102] The windbreak rib (244) can prevent the wind moving downward along the vertical rib (221) from moving forward, thereby increasing the amount of wind moving backward along the lower guide (241).

[0103] Fig. 16 is a drawing showing a state in which a hair styling nozzle (200) according to a first embodiment of the present invention is coupled to a main body head portion (101). As shown in Fig. 16, the main body of the hair dryer (100) has a head portion (101) in which an air discharge portion (103) is positioned in a cylindrical shape extending in the front-back direction, and a handle portion (102) for a user to hold with their hand extends downward from the head portion (101).

[0104] When the hot air of the hair styling nozzle (200) coupled to the front of the main body is supplied to the lower rear of the hair styling nozzle (200) through the lower guide (241), the hot air is supplied to the handle part (102) of the main body, so that the hand (H) holding the handle part (102) may become hot. The hot air supplied to the handle part (102) is lower in temperature than the hot air supplied directly to the lower part of the hair styling nozzle (200), but still affects usability.

[0105] The present invention can additionally add a central guide (245) to the lower guide (241) so that hot air moving to the rear of the hair styling nozzle (200) through the lower guide (241) can be supplied without avoiding the handle.

[0106] Fig. 17 is a cross-sectional view of a hair styling nozzle (200) according to a first embodiment of the present invention. A central guide (245) is positioned between a lower guide (241) and the lower portion of a nozzle head (220), and begins at the lower rear surface of a vertical rib (221) positioned in the center and widens rearward. The central guide (245) includes a pair of inclined surfaces on the left and right sides and may have a symmetrical shape.

[0107] The central guide (245) serves to disperse the hot air moving backward along the lower guide (241) in the left and right directions, thereby guiding it to flow away from the user's hand holding the handle.

[0108] In Fig. 17, a central guide (245) is shown including a straight slope, but may also include a curved surface with a convex shape in the rear direction to guide the wind flow outward.

[0109] Fig. 18 is a drawing showing the flow of wind depending on the presence or absence of a central guide (245) of a hair styling nozzle (200) according to the present invention. (a) In the absence of a central guide (245), the wind flows in the rearward direction and is transmitted to the user's hand (H) holding the handle (102).

[0110] However, if a central guide (245) is provided as in (b), the wind in the central part can move in the left and right directions of the nozzle head along the central guide (245), thereby reducing the hot air transmitted to the handle part (102).

[0111] Figures 19 to 21 are drawings showing the flow of wind according to the size of the central guide (245) of the hair styling nozzle (200) according to the present invention.

[0112] Fig. 19 illustrates the flow of wind in the EE section of Fig. 16. Fig. 19 (a) illustrates the flow of wind when the rear end width of the central guide (245) is 20 mm, (b) illustrates the flow when it is 30.6 mm, and (c) illustrates the flow when it is 40 mm, with (a) being the narrowest and (c) the widest. It can be seen that as the rear end width becomes wider, the amount of hot air supplied to the handle decreases.

[0113] Figure 20 shows the wind flow in the FF cross-section of Figure 16, at a position about 15 mm away from the center, and Figure 21 shows the wind flow in the GG cross-section, at a position about 25 mm away from the center.

[0114] Referring to Fig. 20, when the width of the central guide (245) is narrow (a), wind is discharged from the FF cross-section, but when the width of the central guide is wide (c), wind is induced laterally by the central guide (245) more than the FF position, so wind discharged in the rear direction is not detected.

[0115] Referring to Fig. 21, even in the embodiment (b) where the width of the rear end of the central guide (245) is 30.6 mm, the wind discharged rearward from the GG cross-section toward the lower passage (243) is detected. However, when the width of the rear end of the central guide (245) is 40 mm or more, the wind discharged rearward from the GG cross-section is not detected, as shown in (c).

[0116] As seen in FIGS. 19 to 21, the wider the width of the central guide (245), the less the amount of wind flowing in the direction of the handle can be. However, as the rear end width of the central guide (245) becomes wider, the size of the flow path discharged to the rear of the lower flow path (243) becomes smaller, which may actually impede the flow of wind flowing to the rear. Therefore, the width may be determined within a range of 30 mm to 65 mm.

[0117] This simulation is based on the case where the size of the nozzle head (220) is approximately 100 mm, and the size of the central guide (245) may vary depending on the size of the nozzle head (220).

[0118] Expressed in terms of an angle, the central guide (245) can form an inclined plane within a range of values ​​from 120° to 160° between a pair of inclined planes.

[0119] Since the central guide (245) is located above the lower guide (241), if the lower guide (241) has a slope that slopes downward as it goes downward as in the embodiment described above, the height of the lower guide (241) can also increase as it goes rearward.

[0120] As described above, the hair styling nozzle (200) of the present invention can effectively implement a style that adheres closely to the scalp by guiding the wind to flow downward.

[0121] In addition, the hair styling nozzle (200) of the present invention can prevent burns caused by hot air by preventing hot air from being directly applied to the ears.

[0122] In addition, the hair styling nozzle (200) of the present invention can improve usability because hot air is not transmitted to the hand holding the handle.

[0123] With respect to various embodiments for implementing the present invention, duplicate descriptions are omitted as they have been described above in the previous table of contents, Best Mode for Carrying Out the Invention.

[0124] The present invention is applicable to hair dryers in various fields, and thus its industrial applicability is recognized.
