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 requires separate tools like hairbrushes or heat-generating curling irons, or professional techniques, making it difficult to achieve satisfactory styling 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.

[0010] The elastic fastening member may include a screw that penetrates the air guide and is fastened to the nozzle head; and a spring into which the screw is inserted and interposed between the air guide and the nozzle head.

[0011] The rear coupling portion may include a ring coupling portion positioned around the air discharge portion; and a central coupling portion positioned on the inner side of the rear portion and coupled with a magnet positioned at the center of the air discharge portion; and the air guide may include an outer guide connected from the ring coupling portion to the nozzle head; and a phase plug extending forward from the central coupling portion and having a vertical cross-section that becomes smaller as it goes forward.

[0012] The above elastic fastening member can be fastened to the nozzle head by penetrating the phase plug.

[0013] A flow gap formed between the air guide and the nozzle head; and a sealing ring positioned inside the flow gap and interposed between the air guide and the nozzle head may be included.

[0014] The air guide includes an outer guide connected from the rear joint to the nozzle head, the nozzle head includes a side wall portion that protrudes from the front periphery toward the rear and surrounds the outer periphery of the outer guide, and the sealing ring can be interposed between the side wall portion and the outer guide.

[0015] The sealing ring includes a fixed portion fixed to the outer guide; a contact portion protruding from the fixed portion and in contact with the side wall portion; and a moving portion positioned between the fixed portion and the contact portion, wherein the hardness of the moving portion may be smaller than that of the fixed portion.

[0016] The above contact portion may have a hardness equal to or greater than the moving portion and a hardness less than the fixed portion.

[0017] The above outer guide may include a first fixing rib positioned at the front and rear of the fixing part to support the fixing part and a second fixing rib inserted into the fixing part.

[0018] The above contact portion may have a tube shape with an inner hollow.

[0019] The above contact portion may include a protrusion protruding toward the side wall portion at the end.

[0040] Additionally, the terms used herein are only used to describe specific embodiments and are not intended to limit the present invention.

[0041] Also, in this specification, singular expressions may include plural expressions unless the context clearly indicates otherwise.

[0042] 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.

[0043] 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'.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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).

[0051] 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).

[0052] 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).

[0053] 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.

[0054] 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.

[0055] 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).

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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).

[0061] 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).

[0062] 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).

[0063] 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).

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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).

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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).

[0074] 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).

[0075] 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).

[0076] 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.

[0077] 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.

[0078] 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).

[0079] 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).

[0080] 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.

[0081] 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).

[0082] 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).

[0083] 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.

[0084] 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.

[0085] 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).

[0086] 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.

[0087] Fig. 10 is a horizontal cross-sectional view of a hair styling nozzle (200) according to a second embodiment of the present invention. The hair styling nozzle (200) of the present invention is used in close contact with the user's scalp, and may include an elastic member (262) so that it can come into contact with the scalp without applying strong pressure to the scalp when the user applies pressure in the direction of the scalp.

[0088] A method such as adding rubber material to the protrusions that come into contact with the scalp can be used, but since the hair styling nozzle (200) of the present invention has a large area that comes into contact with the scalp, if the vertical ribs (221) that come into contact with the scalp are formed of rubber, a problem of hair getting caught may occur.

[0089] Accordingly, the present invention can increase 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) touching the scalp can be varied.

[0090] In this embodiment, the connection between the nozzle head (220) and the air guide (230) is implemented through an elastic connection part (260), and the elastic connection part (260) may include a spring (262) as illustrated in FIG. 10. The maximum distance between the air guide (230) and the nozzle head (220) is fixed, but when the nozzle head (220) is pressed backward, the nozzle head (220) may be pushed backward, thereby narrowing the gap between the nozzle head (220) and the air guide (230).

[0091] As described above, the air guide (230) may be composed of a phase plug (235) located in the center and an outer guide (231) located on the outer periphery. The outer guide (231) extends from the ring joint (211) and provides a path through which hot air discharged from the air discharge portion (103) is supplied to the nozzle head (220).

[0092] The phase plug (235) may protrude forward from the central joint (215) and may have a shape that narrows forward. The phase plug (235) may serve to gather hot air discharged from the ring-shaped air discharge portion (103) toward the center.

[0093] The elastic fastening member (260) may include a spring (262) that changes the gap between the nozzle head (220) and the air guide (230) and a screw (261) that restricts the movement of the nozzle head (220) by the spring (262).

[0094] The screw (261) is a member that limits the maximum distance so that the nozzle head (220) and the air guide (230) do not separate, and can be fastened to the screw boss (228) formed in the nozzle head (220) by penetrating the phase plug (235).

[0095] The screw boss (228) protrudes rearward from the front (226) of the nozzle head (220), and since the second front (2262) does not have a nozzle hole facing forward, it can be formed on the second front (2262).

[0096] The screw (261) inserted into the phase plug (235) is not fixed in its forward and backward position relative to the phase plug (235), so that the phase plug (235) can change its relative position with respect to the screw (261). The spring (262) surrounds the outer surface of the screw (261) and can be interposed between the phase plug (235) and the nozzle head (220).

[0097] The spring (262) can adjust the gap between the nozzle head (220) and the air guide (230) by changing its length. Since the phase plug (235) has a curved surface, the portion through which the screw penetrates so that the rear end of the spring (262) is fixed protrudes forward (236) to support the rear end of the spring (262).

[0098] Fig. 10 is a horizontal cross-sectional view of the central portion in the vertical direction. Referring to Fig. 10, the nozzle head (220) may include a side wall portion (225) extending from the front (226) toward the rear. The air guide (230) may be inserted into the rear surface of the nozzle head (220), and an end of the outer guide (231) may be coupled to the inner side of the side wall portion (225) of the nozzle head (220).

[0099] Since the outer guide (231) is inserted from the rear of the nozzle head (220), the joint portion of the outer guide (231) and the nozzle head (220) faces the rear. The joint portion of the outer guide (231) and the nozzle head (220) is spaced apart from the front (226) of the nozzle head (220) where the hair touches, so that the problem of hair getting caught between the outer guide (231) and the nozzle head (220) can be minimized.

[0100] The nozzle head (220) may include a nozzle hook (229) protruding from the rear end of the side wall (225), and the nozzle hook (229) may be connected to the circumference of the outer guide (231) to hold the outer guide (231) so that it does not come off from the nozzle head (220).

[0101] Since the nozzle hook (229) is hooked to the rear side of the outer guide (231), the nozzle head (220) moves in the rear side in the state shown in FIG. 10, and the movement of the outer guide (231) further into the nozzle head (220) is not restricted. In addition to the nozzle hook (229) protruding from the end of the side wall portion (225) of the nozzle head (220), a hook (229') may be further included to prevent the air guide (230) and the nozzle head (220) from being separated.

[0102] (229) is required so that interference does not occur between the nozzle head (220) and the air guide (230) having a structure in which the nozzle head (220) flows. However, the wind introduced into the hair styling nozzle (200) through the flow gap (g) may flow out through the flow gap (g). A sealing ring (250) may be included that allows the flow between the nozzle head (220) and the air guide (230) while simultaneously blocking the wind flowing out through the flow gap (g) between the nozzle head (220) and the air guide (230).

[0103] The sealing ring (250) is interposed between the circumference of the outer guide (231) and the circumference of the side wall portion (225) of the nozzle head (220), and may have a ring shape with both ends connected. Unlike a conventional sealing structure for waterproofing or windproofing, the sealing ring (250) of the present invention has a characteristic cross-sectional shape because it needs to prevent wind from leaking if it has fluidity.

[0104] FIG. 11 is a cross-sectional view illustrating a sealing ring (250) of a hair styling nozzle (200) according to a second embodiment of the present invention.

[0105] The sealing ring (250) is fixed so as to face outward around the outer guide (231) and can come into contact with the inner side of the side wall (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 be in close contact with the nozzle head (220).

[0106] The sealing ring (250) may include a fixed portion (251) fixed to the outer guide (231) and a contact portion (254) that is in close contact with the side wall portion (225) of the nozzle head (220). Between the contact portion (254) and the fixed portion (251), a moving portion (252) that is easily shaped according to the flow of the nozzle head (220) may be included.

[0107] The sealing ring (250) may include an elastic material such as silicone, and the fixed portion (251), the contact portion (254), and the moving portion (252) may be composed of the same material or different materials. However, considering the convenience of manufacturing, they may be composed of the same material but have different thicknesses and shapes to have different characteristics.

[0108] The contact portion (254) has elasticity and can be brought into close contact with the side wall portion (225) of the nozzle head (220), and can be configured to have a large area so as to maintain contact with the side wall portion (225) of the nozzle head (220) even when flowing.

[0109] Fig. 12 is a cross-sectional view illustrating various embodiments of a sealing ring (250) of a hair styling nozzle (200) according to a second embodiment of the present invention. The contact portion (254) may have a semicircular cross-section as in Fig. 12 (a) or may be configured as a rectangle as in Fig. 12 (b). A protrusion (255) or wrinkles, etc. may be formed at the end of the contact portion (254), i.e., the portion in contact with the side wall portion (225).

[0110] The contact portion (254) of the sealing ring (250) can be configured in the form of a tube with an inner side hollow so that it can be in close contact with the side wall portion (225). Since the sealing ring (250) forms a closed curve, the inner side (right side in the drawing) that is coupled to the outer guide (231) like a bicycle tube can be opened to form an empty space inside the contact portion (254).

[0111] The fluid part (252) can minimize movement of the contact part (254) from the side wall part (225) by offsetting the movement according to the flow of the nozzle head (220) by using a material that is easy to change shape.

[0112] The fluid part (252) can be formed with wrinkles to facilitate shape change as illustrated in Fig. 11. The fluid part (252) can be configured to be the same as or thinner than the contact part (254).

[0113] The fixed portion (251) has rigidity so that it can be stably fixed to the outer guide (231), and for rigidity, it can be formed thicker than other portions. However, since there is a risk of detachment due to the nature of the material, it can include fixed ribs (2341, 2342) that fix the sealing ring (250) to the outer guide (231), as illustrated in FIG. 11.

[0114] The fixed rib may include a first fixed rib (2341) that wraps around the inner side and the front side (226) and the back side in addition to the outer side of the fixed part (251), and may include a second fixed rib (2342) that is inserted into the center of the fixed part (251) as well as the periphery of the fixed part (251).

[0115] Since the sealing ring (250) has an open inner shape, the fixing part (251) is partitioned front and rear, so the second fixing rib (2342) can be inserted into the partitioned space of the fixing part (251). The second fixing rib (2342) can be formed in a T shape to minimize the sealing ring (250) from coming off.

[0116] The thickness of the contact portion (254) is configured to be 0.5 mm or less, and the thickness of the fixed portion (251) is configured to be 1 mm or more, so that the thicknesses of the contact portion (254) and the fixed portion (251) can be configured to be several times greater. In this embodiment, the thickness of the contact portion (254) is configured to be 0.3 mm, and the thickness of the fixed portion (251) is configured to be 1.5 mm.

[0117] 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.

[0118] In addition, the hair styling nozzle of the present invention can improve usability by smoothly contacting the scalp through the fluid structure of the nozzle head (220).

[0119] In addition, the hair styling nozzle of the present invention can prevent wind from leaking through the flow gap (g) between the nozzle head (220) and the air guide (230).

[0120] Although the present invention has been illustrated and described with respect to specific embodiments, it will be apparent to those skilled in the art that the present invention may be variously improved and modified without departing from the technical spirit of the invention as defined by the following claims.
