[0002] A hair dryer that emits gas through an air outlet can be used to remove moisture from human hair while it is wet or to style it from its current shape into a desired shape.

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

[0004] Since the heater module is located in the head section, if the case temperature rises due to the heat from the module, there is a risk of burns and it may affect internal components such as the control unit. Therefore, a structure is required whereby the heat from the heater module is entirely transferred to the air passing through the airflow path, rather than being transferred to the outside or other locations.

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

[0006] Hair dryers can be used for hair styling in addition to drying hair. However, achieving satisfactory styling at home is difficult because styling typically requires separate tools such as hair brushes or heat irons, or necessitates professional skills.

[0007] Development is underway for various types of accessories to expand the functionality of hair dryers, making hair styling easier. The problem to be solved

[0035] The present invention relates to a portable device that a user can hold and use with their hand, and refers to an electronic device that is small in size and used by the user by holding it with their hand. Since the portable device is not used while mounted but is held directly by the user, it must be lightweight, and the grip of the handle portion (102) is important. In addition, since contaminants are easily introduced from the outside, a waterproof function may be required. Furthermore, it is necessary to seal the gap between the case and the frame so that internal air is not discharged to an area other than the air discharge portion.

[0036] The portable device of the present invention relates to a beauty device, and a representative example is a hair dryer (100) for hair care. Although the description is based on a hair dryer (100), it is not limited thereto, and portable devices such as skin care devices or body care devices that are held and used by a user may also be included in the present invention.

[0037] 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 a hair dryer (100) according to one embodiment of the present invention. FIG. 3 is a cross-sectional view of a hair dryer (100) according to one embodiment of the present invention, which is the AA cross-section of FIG. 2.

[0038] 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 and -y is the rear, and +z is the up and -z is the down.

[0039] 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 for air to be introduced from the outside, and the head portion (101) may include an air discharge portion (103) for gas discharge, a heater module (150), and a touch display (135) on the back.

[0040] The interior of the main body (101, 102) of the hair dryer (100) includes an air passage extending from the air inlet (104) to the air outlet (103). The air passage of the present invention is not a straight passage, but moves vertically from the handle (102) and then bends horizontally from the head (101), as shown in FIG. 3.

[0041] 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 passage. For usability, the handle (102) may be extended in a direction slightly tilted forward from the vertical direction relative to the head (101).

[0042] The handle portion (102) is composed of a cylinder with a diameter that a user can grasp with their hand, and the head portion (101) can be formed in a cylindrical shape with a larger diameter than the handle portion (102). The diameter of the handle portion (102) can be formed uniformly 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 air comes out at a high speed with strong pressure through the air discharge portion (103).

[0043] The air inlet (104) includes a gas intake hole (1283) formed along the circumference of the handle portion (102) and may include a filter to prevent foreign substances such as dust from entering. A filter frame with a fixed filter may be located at the bottom of the handle portion (102) to form the air inlet (104).

[0044] The filter is made of a different material from the case (111, 121) that forms the exterior of the hair dryer (100), and since it is a thin film-shaped component, it can be damaged by external impact. Therefore, a filter cover (128) to protect the filter may be further included, and the filter cover (128) may be configured to be detachable for cleaning and replacing the filter.

[0045] The air discharge section (103) is located in front of the head section (101) and may include a ring-shaped opening. As shown in FIG. 3, the heating wire (156) of the heater module (150) of the present invention forms a donut shape with a hollow center and is wound around the circumference of a cylindrical heater housing (158). Corresponding to the arrangement of the heating wire (256), the air discharge section (103) may also have a ring shape. That is, the center of the air discharge section (103) may be closed to form a ring shape.

[0046] To extend the function of the hair dryer (100), a styling nozzle (200) that is coupled to the air discharge unit (103) may be further included. The styling nozzle (200) can be easily detachable through a magnet located in the central part of the air discharge unit (103).

[0047] FIG. 4 is a perspective view of a styling nozzle (200) according to a first embodiment of the present invention, and FIG. 5 is a cross-sectional view of a styling nozzle (200) according to a first embodiment of the present invention. FIG. 6 is a front view of a styling nozzle (200) according to a first embodiment of the present invention, and FIG. 7 is a plan view of a styling nozzle (200) according to a first embodiment of the present invention.

[0048] The styling nozzle (200) of the present invention is detachably attached to the air discharge part (103) of the hair dryer (100) and serves to guide the flow of hot air coming from the air discharge part (103).

[0049] The styling nozzle (200) of the present invention can be used for volume-up styling that lifts the hair from the scalp by applying heat to the hair roots. For volume-up styling, a method is used in which the hair near the scalp is wrapped with a roller-shaped comb, and then heat is applied with a hair dryer (100) to fix the shape of the hair.

[0050] However, the process of shaping the hair with a roller comb and fixing it by applying heat with a hair dryer (100) is difficult, which presents a problem in that it is difficult to achieve volume-up styling. The styling nozzle (200) of the present invention is an auxiliary accessory that can be attached to a hair dryer (100) to easily lift the hair away from the scalp without a separate roller comb, thereby facilitating volume-up styling.

[0051] The styling nozzle (200) of the present embodiment includes a rear coupling portion (210) that contacts the air discharge portion (103) and a plurality of comb plates (220) that extend forward from the rear coupling portion (210) and are arranged at predetermined intervals in a first direction. The rear coupling portion (210) may include a ring coupling portion (211) that is coupled to the circumference of the air discharge portion (103) and a central coupling portion (215) located in the center of the ring coupling portion (211) and coupled to the nozzle coupling portion (113) of the main body.

[0052] The first direction (D1) refers to the horizontal direction in the drawing, and the second direction (D2) refers to the vertical direction in the drawing. Since the styling nozzle (200) can be freely connected to the air discharge part (103) of the hair dryer (100) at 360°, the first direction (D1) and the second direction (D2) are used to describe the connection instead of the expressions horizontal and vertical.

[0053] When the styling nozzle (200) is attached to the main body, the ring coupling portion (211) comes into contact with the outer circumference of the air discharge portion (103). Hot air discharged from the air discharge portion (103) passes through a ring-shaped space between the ring coupling portion (211) and the central coupling portion (215), and includes a plurality of comb plates (220) extending forward from the front of the ring coupling portion (211).

[0054] A plurality of comb plates (220) may be spaced apart by a predetermined distance in a first direction (D1), and the comb plates (220) are plate-shaped members that extend in a second direction (D2) perpendicular to the first direction (D1). As shown in FIG. 5, the rear ends of the comb plates (220) are connected to ring joints (211) at both ends in the second direction (D2), and the middle portion can be connected to a central joint (215).

[0055] Referring to FIG. 7, a plurality of comb plates (221) are spaced apart at equal intervals in the first direction (D1), and the thickness in the first direction (D1) may have the same value in the front-rear direction. However, the outer comb plates (222) located at both ends of the first direction (D1) may have a width in the first direction (D1) at the rear end that is thicker than the front end. As shown in FIG. 6, the maximum thickness in the first direction (D1) at the rear end of the outer comb plate (222) may have a value corresponding to the width of the ring joint (211).

[0056] The part where the ring joint (211) is located does not discharge air, so there is no need to provide an additional comb plate (220), and since the outer comb plate (222) is a part that is directly affected by external impact, the rear end can be made thicker to increase the rigidity of the styling nozzle (200).

[0057] As shown in FIG. 5, the width of the second direction (D2) at the rear end is widest, and as it extends forward, the width narrows to form a pointed shape. The comb plate (220) can be configured to have a longer section where the width of the second direction (D2) is narrow so that it can be easily inserted between the hair and allows for natural volume-up styling. As shown in FIG. 5, the slope of the rear end can be formed steeply to create a concave slope towards the center of the second direction (D2).

[0058] When a comb plate (220) is attached to the hair and hot air is applied, the hot air can be supplied to the hair attached to the comb plate (220), allowing for volume-up styling without a separate roller brush.

[0059] Referring to FIG. 1, the air discharge part (103) of the hair dryer (100) may have a ring shape and may include a nozzle coupling part (113) equipped with a magnet for coupling with a styling nozzle (200) in the closed part in the center.

[0060] The styling nozzle (200) may include a central coupling part (215) having a nozzle magnet with an opposite pole to the magnet of the nozzle coupling part (113). The central coupling part (215) is located in the center of the ring coupling part (211) and may be arranged to form a uniform spacing with respect to the inner circumference of the ring coupling part (211).

[0061] The center of the central coupling part (215) and the center of the ring coupling part (211) are arranged in concentric circles such that they are the same, and the outer circumference of the ring coupling part (211) and the outer circumference of the central coupling part (215) may coincide with the ring-shaped discharge port of the air discharge part (103).

[0062] It may include a phase plug (230) protruding forward from the central coupling portion (215). As shown in FIG. 5, the phase plug (230) may serve as a guide to collect hot air discharged in a ring shape towards the center of the second direction (D2), with the front end formed sharply.

[0063] Additionally, the phase plug (230) has multiple comb plates (220) connected only to the ring joint (211) and both ends of the second direction (D2), so it is weak against impact in the first direction (D1) and is at risk of damage. The phase plug (230) can be configured as an integral unit with the multiple comb plates (220) to improve the rigidity of the comb plates (220).

[0064] That is, the comb plate (220) can be prevented from shaking or being damaged in the first direction (D1) by having its rear end connected to the ring joint (211) or the phase plug (230), except for the section between the ring joint (211) and the central joint (215).

[0065] The phase plug (230) can be visually exposed between the multiple comb plates (220) as in FIG. 6 and FIG. 7, but as shown in FIG. 5, the size of the second direction (D2) is smaller than the comb plate (220) and does not protrude from the comb plate (220).

[0066] The central coupling portion (215) forms a circular shape in the first direction (D1) and the second direction (D2) as shown in FIG. 6 so as to match the nozzle coupling portion (113) of the hair dryer (100). However, since the phase plug (230) acts as a guide to gather the air to the center of the second direction, the shape in the first direction (D1) and the shape in the second direction (D2) may be different as shown in FIG. 5 and FIG. 7.

[0067] The wind in the first direction (D1) is not spread laterally by the plurality of comb plates (220), so the shape of the phase plug (230) does not significantly affect the direction of the wind, and can form a curved surface that is convex forward as in FIG. 7, a rectangular shape, or a shape in which the outline of the planar view is a straight line.

[0068] However, the wind in the second direction (D2) is not blocked from the top and bottom, so it is affected by the cross-sectional shape of the second direction (D2) of the phase plug (230). FIG. 8 is a drawing illustrating the flow of hot air of a styling nozzle (200) according to the first embodiment of the present invention, where (a) is a drawing illustrating the flow of hot air in part (a) of FIG. 7 and (b) is a drawing illustrating the flow of hot air in the cross-section of (b) of FIG. 7.

[0069] (a) illustrates the hot air flow in the central part of the first direction (D1) where the phase plug (230) is most protruding, and (b) illustrates the hot air flow in the end part. As shown in (a), hot air is discharged from both sides of the second direction (D2) of the phase plug (230) in the central part of the first direction (D1), and since the wind moves along the outer surface of the phase plug (230), it can be confirmed that the wind moves in correspondence with the shape of the phase plug (230).

[0070] As shown in Fig. 8(b), the end portion of the first direction (D1) has a gas discharge port located only in the center of the second direction (D2), so hot air is discharged in a straight line from the center portion, but as shown in Fig. 8(a), the central portion tends to spread widely in the second direction (D2).

[0071] The shape of the phase plug (230) can be changed to guide the flow of hot air in the central part of the first direction (D1) to be concentrated in the center of the second direction (D2).

[0072] FIG. 9 is a cross-sectional view of a styling nozzle (200) according to a second embodiment of the present invention, and FIG. 10 is a drawing illustrating the airflow of a styling nozzle (200) according to a second embodiment of the present invention.

[0073] As shown in FIG. 9, the shape of the second direction (D2) cross-section of the phase plug (230) has a concave shape, unlike the previously described embodiment. Like the comb plate (220), the slope at the rear end is steeper and the slope at the front end is gentle, forming a pointed shape, and the outer surface of the second direction (D2) cross-section can be positioned at the same distance as the outer edge of the comb plate (220).

[0074] FIG. 10(a) illustrates the flow of hot air in the central part of the first direction (D1) of the embodiment of FIG. 9, and FIG. 10(b) illustrates the flow of hot air in the end of the first direction (D1) of the embodiment of FIG. 9. Referring to FIG. 10(b), the flow of hot air in the end of the first direction (D1) does not differ significantly from the previously described embodiment. That is, the flow of hot air in the end of the first direction (D1) is not significantly affected by the shape of the phase plug (230).

[0075] However, referring to (a) of FIG. 10, since the hot air moves along the outer surface of the phase plug (230) in the central part, it can be seen that the hot air tends to gather towards the center compared to (a) of FIG. 8.

[0076] FIG. 11 is a perspective view of a styling nozzle (200) according to a third embodiment of the present invention, and FIG. 12 is a cross-sectional view of a styling nozzle (200) according to a third embodiment of the present invention. The styling nozzle (200) of the present embodiment may include a locking end extended at the front end of a comb plate (220). The locking end refers to a portion having a shape protruding from the front end of the comb plate (220), and may include a first locking end (225) extended in a second direction (D2) as shown in FIG. 12.

[0077] The first locking end (225) may be extended only to one side of the second direction (D2), but may have a shape that is symmetrically extended to both sides of the second direction (D2) as shown in FIG. 12. It may include a first inclined surface (225d) extending from the maximum protrusion (225a) of the first locking end (225) to the front end (225c) and a second inclined surface (225e) extending to the rear end (225b).

[0078] The first inclined surface (225d) and the second inclined surface (225e) may be symmetrical, and as shown in FIG. 12, the second inclined surface (225e) may be composed of a stepped portion that is steeper or forms a 90° angle relative to the first inclined surface (225d).

[0079] The first locking end (225) can be configured in an arrowhead shape by creating a difference in the slope between the first inclined surface (225d) and the second inclined surface (225e). It is characterized by being easy to insert between hairs, but easy to pull out of hairs only in a direction that does not interfere with the first locking end (225).

[0080] The width (a) of the second direction (D2) of the maximum protrusion (225a) of the first catch portion (225) can be configured to have a size of 150% or 250% of the width (b) of the rear portion (225b). Since there is no hair catch effect if it is too large and there is a problem of hair tangling if it is too small, it can be configured to have a size within the range of 1.5 to 2.5 times.

[0081] FIG. 13 is a drawing illustrating the airflow of a styling nozzle (200) according to a third embodiment of the present invention. (a) illustrates the hot air flow in the central part of the first direction (D1), and (b) illustrates the hot air flow in the end part of the first direction (D1).

[0082] It can be confirmed that the flow of hot air shown in Fig. 13 is almost the same as that of Fig. 10, so when the first catch portion (225) is added to the front portion of the comb plate (220), it does not have an adverse effect on the flow of hot air.

[0083] FIG. 14 is a perspective view of a styling nozzle (200) according to a fourth embodiment of the present invention, and FIG. 15 is a cross-sectional view of a styling nozzle (200) according to a fourth embodiment of the present invention. In this embodiment, even though the shape of the phase plug (230) was modified in the aforementioned second or third embodiment, it is difficult to obtain a temperature sufficient to fix the hair by spreading the air in the second direction (D2).

[0084] Accordingly, in order to concentrate the wind further towards the center and increase the temperature of the hot air, this embodiment is characterized by including an outer guide (240) that wraps around the rear circumference of the comb plate (220). The outer guide (240) extends forward from the outer circumference of the ring joint (211) and wraps around the outer side of the comb plate (220).

[0085] As shown in FIG. 15, the diameter of the front end of the second direction (D2) is smaller than that of the rear end, and the hot air discharged from the air discharge section (103) can be guided to flow towards the center of the second direction (D2) while flowing along the path between the outer guide (240) and the phase plug (230).

[0086] FIG. 16 is a diagram illustrating the airflow of a styling nozzle (200) according to a fourth embodiment of the present invention. As shown in FIG. 16 (a), the flow is directed toward the center, thereby increasing the speed of the hot air and allowing the hot air to be supplied intensively to the part to be styled.

[0087] If the length of the outer guide (240) is too long, it is difficult to insert hair between the comb plates (220), so the length protruding forward from the phase plug (230) may be short.

[0088] That is, the position of the front end of the outer guide (240) is located behind the front end of the phase plug (230), and the embodiment of FIG. 14 is configured so that the position of the front end of the outer guide (240) forms a straight line. However, if the front end of the outer guide (240) is extended only to the same position, the length of the outer guide (240) is shortened at the end portion of the first direction (D1) as shown in FIG. 14.

[0089] The comb plate (220) at the end of the first direction (D1) has a shorter length in the second direction (D2), so the extension length of the outer guide (240) is also relatively shorter compared to the center. Since the outer guide (240) is not effective at the end portion of the first direction (D1), the front portion of the outer guide (240) at the end of the first direction (D1) can be extended to be located further forward than the center portion (not shown).

[0090] As seen above, the hair styling nozzle (200) of the present invention can guide the wind to be gathered in a straight line from the circular air discharge part (103).

[0091] In addition, the hair styling nozzle (200) of the present invention can fix the shape of the hair and apply heat without using a separate brush.

[0092] In addition, the hair styling nozzle (200) of the present invention has a catch projection formed at the end, so that hair does not slip out of the comb during styling, which has the advantage of making hair styling easier.

[0093] Although the present invention has been illustrated and described in relation to specific embodiments, it will be obvious to those skilled in the art that the present invention can be modified and changed in various ways without departing from the technical spirit of the invention as provided by the following claims.
