Description

Technology Field

[0001] The present invention relates to a hair curl attachment and a hair styling device including the same. More specifically, the invention relates to a hair curl attachment capable of selectively discharging air in both clockwise and counterclockwise directions using a single hair curl attachment, and a hair styling device including the same. Background Technology

[0003] A hair styling device is generally a type of beauty tool used to create a beautiful hairstyle, such as forming curls or partial waves in the user's hair according to their preference. Examples of hair styling devices include hair irons and hot styling brushes.

[0004] Recently, a hair styling device has been developed that automatically wraps and curls the hair around the head by blowing air along the surface of the head and attracting and wrapping the hair through an aerodynamic phenomenon called the 'Coanda effect'.

[0005] This type of hair styling device attracts and wraps the hair with air, allowing for styling without excessive heat damage. Since there is no need to use a bristle-type brush, the hair can slide out of the head once styling is complete, which has the advantage of being tangle-free.

[0006] In a hair styling device of this type, evenly flowing an appropriate amount of air along the surface of the head is a major factor determining hair curling performance, and various attempts are being made to improve hair curling performance through this.

[0007] The inventor has filed and registered a patent for a hair curler head that curls a user's hair by causing the discharged wind, which is coupled to the tip of a wind discharge device, to flow along the surface of a cylindrical head.

[0008] However, the above-mentioned hair curler head had a problem in that airflow was directed only in one direction (e.g., clockwise) of the nozzle body, requiring the user to prepare and switch between separate hair curler heads that direct airflow in the opposite direction (e.g., counterclockwise) for the user's left and right hair to style their hair. Prior art literature

[0012] The technical problems that the present invention aims to solve are not limited to those mentioned above, and other unmentioned technical problems will be clearly understood by those skilled in the art to which the present invention belongs from the description below. means of solving the problem

[0014] According to one aspect of the present invention, a hair curl attachment coupled to a wind discharge device is provided, comprising: a cylindrical nozzle body having an inlet for air to enter at one end and nozzle slots formed at regular intervals along the circumferential direction in the longitudinal direction; and a wind guide inserted inside the nozzle body and changing the discharge direction of the air by closing one side of the nozzle slot and opening the other side, or closing the other side of the nozzle slot and opening one side, depending on rotation relative to the nozzle body.

[0015] The nozzle body may include a plurality of nozzle slats formed along the circumferential direction at regular intervals so as to form the nozzle slot.

[0016] The above wind guide may include a first sleeve formed at regular intervals to form a guide slot, and having a plurality of opening and closing slats formed to close one side or the other side of the nozzle slot according to rotation relative to the nozzle body.

[0017] Step grooves are formed at both ends of the inner circumference of the nozzle slat, and depending on rotation relative to the nozzle body, both ends of the opening / closing slat can be selectively inserted into the step grooves at both ends.

[0018] The outer surface of the nozzle slat may be formed in an arc shape so that air discharged from one side or the other side of the nozzle slot flows along the surface of the nozzle body.

[0019] An arc-shaped protrusion may be formed in the central part of the above-mentioned opening / closing slat, which contacts one side or the other side of the nozzle slot depending on rotation relative to the nozzle body.

[0020] The above wind guide may further include a second sleeve inserted inside the first sleeve, wherein a guide slat is formed corresponding to each of the guide slots so as to guide the wind into the guide slots.

[0021] The above-mentioned guide slat may include a base portion spaced apart from each end portion of the opening and closing slats adjacent to each other to form a wind path, and a convex portion between the base portions.

[0022] According to another aspect of the present invention, a hair styling device is provided, comprising: a wind discharge device for generating and discharging wind; and an attachment for hair curls coupled to the wind discharge device. Effects of the invention

[0024] According to an embodiment of the present invention, air can be discharged in both clockwise and counterclockwise directions using a single hair curl attachment.

[0025] In addition, by allowing some of the air blown into the nozzle body to be discharged to the outside through the slot and some to be circulated along the inner surface of the nozzle body, the air can be made to flow along the surface of the nozzle body with an appropriate amount of airflow.

[0026] In addition, since the nozzle body and air guide manufactured through a molding process are assembled to produce the head, there is an advantage in that the manufacturing process is simplified. Brief explanation of the drawing

[0033] FIG. 1 is a perspective view of a hair curl attachment according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of the hair curl attachment shown in FIG. 1. FIG. 3 is a cross-sectional view of the hair curl attachment shown in FIG. 1. FIG. 4 and FIG. 5 are drawings for explaining the operating state of a hair curl attachment according to an embodiment of the present invention.

[0034] FIGS. 1 to 5 illustrate a hair curl attachment (10), a handle (12), a connecting part (14), a nozzle body (16), a nozzle slot (18), a nozzle slat (20), a stepped groove (21), a rib (22), a wind guide (23), a first sleeve (24), a guide slot (26), an opening / closing slat (28), an arc-shaped protrusion (30), a second sleeve (32), a guide slat (34), a base part (36), and a convex part (38).

[0035] The hair curl attachment (10) according to the present embodiment is a hair curl attachment (10) coupled to a wind discharge device, and comprises: a cylindrical nozzle body (16) having an inlet for wind to enter at one end and nozzle slots (18) formed at regular intervals along the circumferential direction in the longitudinal direction; and a wind guide body (23) inserted inside the nozzle body (16) and changing the direction of wind discharge by closing one side of the nozzle slot (18) and opening the other side, or closing the other side of the nozzle slot (18) and opening one side, depending on rotation relative to the nozzle body (16).

[0036] The hair curl attachment (10) according to the present embodiment is attached to the discharge port (42) of the wind discharge device (40) as shown in FIG. 6, and can perform hair styling by guiding the wind generated from the wind discharge device (40) along the surface of the nozzle body (16) in a clockwise or counterclockwise direction so that human hair is wrapped around it.

[0037] The wind discharge device (40) may be configured as a dedicated bar-shaped wind discharge device (40) as shown in FIG. 6, or as a multi-purpose hair dryer.

[0038] The nozzle body (16) is cylindrical in shape and has an inlet at one end through which air enters, and open nozzle slots (18) are formed at regular intervals along the circumferential direction.

[0039] The nozzle body (16) is designed to guide and discharge wind formed in a wind discharge device along the surface of the nozzle body (16) in a clockwise or counterclockwise direction, and has a cylindrical structure in which an inlet is formed at one end and the other end is closed.

[0040] In the cylindrical nozzle body (16), multiple open nozzle slots (18) are formed at regular intervals along the circumference, and by blocking one of the long sides of the nozzle slots (18) that face each other and opening the other side, the wind can be made to flow in a clockwise or counterclockwise direction.

[0041] The wind guide (23) is inserted into the interior of the nozzle body (16) and, depending on rotation relative to the nozzle body (16), closes one side of the nozzle slot (18) and opens the other side, or closes the other side of the nozzle slot (18) and opens one side, thereby changing the direction of wind discharge.

[0042] The wind guide (23) is inserted into the interior through the inlet of the nozzle body (16) and rotates relative to the nozzle body (16). For example, the wind guide (23) can be rotated while the nozzle body (16) is fixed, the nozzle body (16) can be rotated while the wind guide (23) is fixed, or the nozzle body (16) and the wind guide (23) can be rotated simultaneously in opposite directions. In this embodiment, a handle (12) is provided fixed to the top of the nozzle body (16), and the wind guide (23) is configured to rotate while the user holds the handle (12).

[0043] Depending on the relative rotation of the nozzle body (16) and the wind guide (23), one side or the other side of the nozzle slot (18) of the nozzle body (16) can be closed or opened, and the wind discharged to the nozzle body (16) can be guided in a clockwise or counterclockwise direction.

[0044] Referring to FIGS. 4 and 5, it can be seen that depending on the relative rotation of the nozzle body (16) and the wind guide (23), one side or the other side of the nozzle slot (18) is closed or opened, and the wind discharge direction is changed to a clockwise or counterclockwise direction.

[0045] The nozzle body (16) includes a plurality of nozzle slats (20) formed along the circumferential direction at regular intervals so as to form nozzle slots (18). The nozzle slats (20) are in the form of long, thin plates and are formed at regular intervals along the circumferential direction of the nozzle body (16) so as to form nozzle slots (18) between them.

[0046] Ribs (22) may be formed intermittently between the nozzle slats (20) to prevent deformation of the nozzle body (16) or to increase rigidity.

[0047] The wind guide (23) includes a first sleeve (24) formed at regular intervals to form guide slots (26) and having a plurality of opening and closing slats (28) formed to close one side or the other side of the nozzle slot (18) according to rotation relative to the nozzle body (16).

[0048] Referring to FIG. 2, the first sleeve (24) is inserted into the nozzle body (16) as part of the wind guide (23), and an opening / closing slat (28) is positioned along the lengthwise at a position corresponding to the nozzle slot (18), and the opening / closing slat (28) moves to one side or the other side of the nozzle slot (18) according to the relative rotation of the nozzle body (16) and the first sleeve (24), thereby changing the direction of wind discharge from the nozzle slot (18).

[0049] As the opening and closing slats (28) are formed at regular intervals in the circumferential direction, open guide slots (26) that guide the wind, which will be described later, are formed at regular intervals between them.

[0050] Referring to FIG. 3, step grooves (21) are formed at both ends of the inner circumference of the nozzle slat (20), and depending on the relative rotation of the first sleeve (24) with respect to the nozzle body (16), both ends of the opening / closing slat (28) can be selectively inserted into the step grooves (21) at both ends.

[0051] In order for the opening / closing slat (28) of the first sleeve (24) to properly close one side or the other side of the nozzle slot (18) according to rotation, a stepped groove (21) is formed at each end of the inner circumference of the nozzle slat (20), and as the end of the opening / closing slat (28) is inserted into the stepped groove (21) according to rotation relative to the nozzle body (16), the one side or the other side of the nozzle slat (20) is closed.

[0052] Referring to FIG. 3, as the first sleeve (24) rotates counterclockwise with respect to the nozzle body (16), the left end of the opening / closing slat (28) is inserted into the right step groove (21) of the nozzle slat (28), thereby closing the left side of the nozzle slot (18) and opening the right side.

[0053] Meanwhile, the outer surface of the nozzle slat (20) may be formed in an arc shape so that the wind discharged from one side or the other side of the nozzle slot (18) flows along the surface of the nozzle body (16), as shown in FIG. 3.

[0054] The attachment (10) for hair curling according to the present embodiment is configured so that the user's hair is wrapped around the nozzle body (16) as the air discharged from the nozzle slot (18) is guided along the cylindrical surface of the nozzle body (16). To this end, the nozzle slat (20), which forms the outer surface of the nozzle body (16) so that the air discharged from one side or the other side of the nozzle slot (18) flows well along the surface of the nozzle body (16), can be formed in an arc shape as shown in FIG. 3.

[0055] In addition, to enhance the surface induction of wind, an arc-shaped protrusion (30) may be formed in the central part of the opening / closing slat (28) located corresponding to each nozzle slot (18), which contacts one side or the other side of the nozzle slot (18) according to rotation relative to the nozzle body (16).

[0056] Referring to FIG. 4, as the wind guide (23) rotates clockwise relative to the nozzle body (16), the opening / closing slat (28) moves to the right side of the nozzle slot (18), and the arc-shaped protrusion (30) located in the center of the opening / closing slat (28) moves to the right side of the nozzle slot (18). At this time, the wind discharged from the left side of the open nozzle slot (18) travels up along the arc-shaped protrusion (30) and is guided clockwise again along the arc-shaped outer surface of the nozzle slat (20).

[0057] Conversely, referring to FIG. 5, as the wind guide (23) rotates counterclockwise relative to the nozzle body (16), the wind discharged from the right side of the nozzle slot (18) is guided along the arc-shaped outer surface of the adjacent nozzle slat (20) of the arc-shaped protrusion (30).

[0058] Meanwhile, referring to FIG. 2, the wind guide body (23) may include a second sleeve (32) in which a guide slat (34) is formed corresponding to each guide slot (26) so that the wind is guided into the guide slot (26) of the first sleeve (24).

[0059] The second sleeve (32) is inserted and fixed inside the first sleeve (24) to form a single wind guide body (23). The second sleeve (32) guides the wind entering the interior of the second sleeve (32) through the inlet to flow along the guide slot (26) of the first sleeve (24) before discharge from the nozzle body (16).

[0060] Referring to FIG. 3, the wind entering the interior of the second sleeve (32) through the inlet is guided to the guide slot (26) of the first sleeve (24) by the guide slat (34), and the wind guided to the guide slot (26) is discharged in a clockwise or counterclockwise direction as one side or the other side of the nozzle slot (18) opens according to the relative rotation of the nozzle body (16) and the wind guide body (23).

[0061] The guide slat (34) of the second sleeve (32) forms a wind guide path to the guide slot (26) together with the opening / closing slat (28) of the first sleeve (24). Referring to FIG. 3, the guide slat (34) may include a convex portion (38) between the base portion (36) and the base portion (36), which are spaced apart from each other at one end of the adjacent opening / closing slats (28).

[0062] The wind flowing into the interior of the second sleeve (32) increases its speed of movement as the gap between the end portion of the adjacent opening / closing slat (28) and the base portion (36) of the guide slat (34) is narrowed, and the wind with increased speed is strongly guided along the surface of the central convex portion (38) toward the center of the guide slot (26). The wind guided at a strong speed is discharged to the outside depending on the opening of one side or the other side of the nozzle slot (18). At this time, the wind that is not discharged to the outside is guided again between the guide slats (34) of the second sleeve (32) and flows back into the guide slot (26) together with the wind flowing in from the interior of the second sleeve (32).

[0063] Referring to FIG. 4, the air flowing into the second sleeve (32) while closing the right side of the nozzle slot (18) is discharged along the nozzle body (16) in a clockwise direction. The air flowing into the second sleeve (32) is combined with the air from the guide slot (26) that was not discharged out, and rotates clockwise while drawing a waveform between the first sleeve (24) and the second sleeve (32).

[0064] In this way, the wind from the guide slot (26) that was not discharged out and the wind introduced into the interior of the second sleeve (32) are combined, so that some of it is discharged and some of it is circulated along the inner surface of the nozzle body (16), thereby allowing the wind to flow along the surface of the nozzle body (16) with an appropriate amount of airflow.

[0065] Conversely, referring to FIG. 5, the wind that enters the interior of the second sleeve (32) while closing the left side of the nozzle slot (18) is discharged along the nozzle body (16) in a counterclockwise direction. The wind that enters the interior of the second sleeve (32) and the wind from the guide slot (26) that was not discharged out are combined, and rotate in a counterclockwise direction while drawing a wave between the first sleeve (24) and the second sleeve (32).

[0066] FIGS. 4 and FIGS. 5 are drawings for explaining the operating state of an attachment munch for hair curls according to an embodiment of the present invention.

[0067] Referring to FIG. 4, as the wind guide (23) rotates clockwise relative to the nozzle body (16), the wind introduced into the interior of the second sleeve (32) travels along the guide slats (34) of the second sleeve (32) and is guided to the guide slot (26) of the first sleeve (24). A portion of the wind guided to the guide slot (26) is discharged through the open right side of the nozzle slot (18) and is discharged clockwise along the outer surface of the nozzle body (16). At this time, the wind from the guide slot (26) that is not discharged outward is introduced again between the guide slats (34) of the second sleeve (32) and is guided to the adjacent guide slot (26) in a clockwise direction together with the wind discharged from the interior of the second sleeve (32). That is, the wind that is not discharged outward rotates clockwise along the inner surface of the nozzle body (16) while drawing a wave pattern.

[0068] Conversely, referring to FIG. 5, as the wind guide (23) rotates relatively counterclockwise with respect to the nozzle body (16), the wind introduced into the interior of the second sleeve (32) travels along the guide slats (34) of the second sleeve (32) and is guided to the guide slot (26) of the first sleeve (24). A portion of the wind guided to the guide slot (26) is discharged through the open left side of the nozzle slot (18) and is discharged counterclockwise along the outer surface of the nozzle body (16). At this time, the wind from the guide slot (26) that is not discharged outward is drawn back into the guide slats (34) of the second sleeve (32) and is guided to the adjacent guide slot (26) in a counterclockwise direction together with the wind discharged from the interior of the second sleeve (32). That is, the wind that is not discharged outward rotates along the inner surface of the nozzle body (16) in a counterclockwise wave pattern.

[0069] FIG. 6 is a front view of a hair styling device according to one embodiment of the present invention.

[0070] In FIG. 6, an attachment (10) for hair curling, a wind discharge device (40), and a discharge port (42) are shown.

[0071] A hair styling device according to the present embodiment includes a wind discharge device (40) that generates and discharges wind; and a hair curl attachment (10) coupled to the wind discharge device (40).

[0072] The wind discharge device (40) is equipped with a blower fan inside to generate wind and discharges wind through the discharge port (42). The hair curl attachment (10) coupled to the discharge port (42) of the wind discharge device (40) allows the wind generated by the wind discharge device (40) to flow along the surface of the hair curl attachment (10), thereby wrapping the user's hair around the surface of the hair curl attachment (10) to style the hair.

[0073] The hair curl attachment (10) according to the present embodiment can change the rotational direction of the wind discharged from the hair curl attachment (10) to a clockwise or counterclockwise direction depending on the relative rotation of the nozzle body (16) and the wind guide (23).

[0074] The wind discharge device (40) illustrated in FIG. 6 is a bar-shaped wind discharge device that forms a hair styling device by combining the coupling part (14) of the attachment (10) for hair curl described above with the discharge port (42).
