Description

Technology Field

[0001] The present invention relates to an electric hair iron, and more specifically, to an electric hair iron in which the hair rod is implemented as a detachable type to enable rapid hair rolling. Background Technology

[0002] Generally, a hair straightener is a beauty tool used to create various hairstyles and enhance hair aesthetics. It is a tool that utilizes a built-in heater to transfer heat, which is then used to straighten hair or form waves using a straightening clip and a roller brush. When the heater heats up, a hair treatment liquid or water is sprayed onto the hair, and the hair is styled by winding it around the straightener or straightening it.

[0003] The prior art for hair irons is as follows. Korean registered patent No. 10-0539586 (hereinafter referred to as 'Prior Art 1') relates to an electric hair straightener having the function of straightening hair and the function of forming curls simultaneously, comprising: a handle (10) equipped with a current supply switch (12); a first heating member (20) coupled to one end of the handle (10), having a flat surface and a curved surface formed in the longitudinal direction, and generating heat according to the operation of the switch (12); a second heating member (30) rotatably coupled to one end of the handle (10), making surface contact with the flat surface of the first heating member (20), and generating heat according to the operation of the switch (12); a corrugated portion (56) formed along the longitudinal direction on the outer side of the second heating member (30); a second curl-forming member (50) rotatably coupled to the corrugated portion (56) of the second heating member (30); and the first It is characterized by including a first curl-forming member (40) that is in surface contact with the curved surface of the heating member (20).

[0004] Korean Registered Utility Model No. 20-0187536 (hereinafter referred to as 'Prior Art 2') relates to a hair iron capable of styling hair in various styles, characterized by comprising: a winding surface formed along a circumferential direction to allow hair to be wound; a heating rod that heats the hair wound on the winding surface and has a heating member built into the winding surface to heat the winding surface; a hair fixing member that is coupled to be spaced apart from the winding surface around a pivot axis formed on one side of the heating rod and fixes the hair to the winding surface; and at least one spiral guide member that is detachably coupled to the circumference of the heating rod and has a guide rib that extends along the radial direction of the heating rod and is formed in a spiral shape along the longitudinal direction to guide the hair to be wound in a spiral shape.

[0005] However, in the case of the prior art 1, the angle at which the first curl-forming member (40) is separated from the first heating member (20) is small, so the treatment space is narrow, and thus the hair can only be wound around the first heating member (20) about once. Therefore, in order to form a curl in the hair, the electric hair iron itself must be rotated repeatedly while the hair is wound around the first heating member (20). Consequently, there was a problem in that the operation of the electric hair iron was not easy, and the treatment took a long time.

[0006] Meanwhile, in the case of prior art 2, the angle between the hair fixing member and the heating member is limited to a very small angle, so it contained the same problem as the aforementioned prior art 1. In addition, since the hair fixing member is formed only on one side of the heating member, the hair easily unravels, and consequently, there was a problem that it was difficult to create a desired hairstyle.

[0007] Due to these issues, conventional hair irons pose a problem for hairdressers who have to stand for long periods, as they exert significant strain on their hands, arms, and shoulders, making them prone to occupational diseases such as muscle pain or nerve pain, and requiring a long time to style hair.

Specific details for implementing the invention

[0025] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Note that in the accompanying drawings, identical components are indicated by the same reference numerals whenever possible. Furthermore, detailed descriptions of known functions and configurations that may obscure the essence of the invention will be omitted. For the same reason, some components in the accompanying drawings may be exaggerated, omitted, or schematically depicted.

[0026] FIG. 1 is a perspective view of an electric hair iron according to one embodiment, FIG. 2 is a perspective view of an electric hair iron viewed from a different direction, FIG. 3 is a perspective view illustrating a situation where the hair rod is closed by gripping the electric hair iron, FIG. 4 is a perspective view showing only the hair rod, and FIG. 5 is a perspective view showing only the body of the hair iron.

[0027] Referring to FIGS. 1 to 5, the electric hair iron (A) according to the present invention includes a hair iron body (2000) and a hair rod (1000).

[0028] The hair straightener body (2000) is in the shape of a clamp and provides heat to the end of one branch forming the clamp.

[0029] The hair rod (1000) is attached to the end of one branch forming the clamp of the hair straightener body (2000), and maintains the hair in a wound shape by closing.

[0030] The hair rod (1000) includes a body part (100), a cover part (200), and a hinge part (300).

[0031] The body portion (100) has a cylindrical shape as a part on which hair (not shown) is placed. The body portion (100) may be formed of a synthetic resin material and, depending on the embodiment, may further include comb-shaped setting protrusions (not shown).

[0032] The cover portion (200) has a semicircular shape that wraps around the upper surface of the body portion (100) so that the hair placed on the body portion (100) forms a wave.

[0033] In the illustrated embodiment, since the body portion (100) has a round cylindrical shape to form waves in the hair, it is preferable that the cover portion (200) has a semicircular shape corresponding to the body portion (100). However, depending on the hair shape to be styled, the cross-sectional shape of the body portion (100) and the cover portion (200) may be appropriately modified.

[0034] The cover portion (200) may have a plurality of through slits (210) on its upper surface for the penetration of a chemical used on hair.

[0035] One end of the cover portion (200) is rotatably connected to one end of the body portion (100). That is, the cover portion (200) and the body portion (100) form a clamp shape through the connection at the ends.

[0036] The hinge portion (300) is coupled to the cover portion (200) so that one end of the cover portion (200) can rotate to one end of the body portion (100).

[0037] Although not an illustrated embodiment, the hinge portion (300) can be implemented simply in the form of a fixing pin that penetrates one end of the cover portion (200) and one end of the body portion (100).

[0038] The cover portion (200) includes a locking fixing member (220) located at the other end. The locking fixing member (220) is locked and fixed to a locking projection (120) provided at the other end of the body portion (100) so that the cover portion (200) is kept in a closed state relative to the body portion (100).

[0039] At this time, as in the illustrated embodiment, the hair rod (1000) may have a form in which the fixed shaft (T) and the slit groove (S) are combined so that the connection between the cover part (200) and the body part (100) has a horizontal gap.

[0040] That is, the hinge portion (300) can be implemented in the form of a fixed shaft (T) protruding from the end of the body portion (100) and a slit groove (S) formed at the end of the cover portion (200). Although not illustrated, depending on the embodiment, the hinge portion (300) may be implemented in a form where the fixed shaft (T) is located in the cover portion (200) and the slit groove (S) is provided in the body portion (100).

[0041] Meanwhile, the locking fixing member (220) can be fixed in a manner that allows it to be fitted into the locking projection (120) by the clearance created by the slit (S). Since the cover portion (200) has a clearance movement parallel to the longitudinal direction of the body portion (100), after the closing operation of the cover portion (200), the cover portion (200) can be pushed to the left of the illustration reference so that the locking fixing member (220) is fitted into the locking projection (120).

[0042] However, the illustrated embodiment is merely one of several possible embodiments and is not intended to limit the scope of the invention. Depending on the implementer, the engaging method of the engaging fixing member (220) and the engaging projection (120) can be implemented in various ways.

[0043] The hair straightener body (2000) includes a lower clamp part (500), a heating rod (600), an upper clamp part (700), and a cover holder (800).

[0044] The lower clamp part (500) forms the lower body of the hair iron body (2000). That is, the lower clamp part (500) forms the branch located below the center of the two clamp-shaped branches.

[0045] The heating rod (600) extends from the lower clamp part (500) and is equipped with a heater inside. The heating rod (600) may be implemented as an integral part with the lower clamp part (500) by injection molding, or it may be implemented by attaching a separate metal material to the lower clamp part (500). A configuration for controlling the temperature of the heating rod (600) may be placed in the inner space of the lower clamp part (500).

[0046] The upper clamp part (700) forms the upper body of the hair iron body (2000). That is, the upper clamp part (700) forms the branch located above the city standard among the two clamp-shaped branches.

[0047] The upper clamp part (700) is rotatably connected to the lower clamp part (500) so that the hair iron body (2000) takes on a clamp shape. The upper clamp part (700) may further be provided with an elastic member (not shown) at the part where the lower clamp part (500) is connected, which maintains an open state when no force is applied to the hair iron body (2000).

[0048] The cover holder (800) extends from the upper clamp part (700) and links the opening and closing operation of the hair iron body (2000) to the hair rod (1000).

[0049] The cover holder (800) can be formed integrally with the upper clamp part (700) by means of injection molding or the like.

[0050] The cover holder (800) includes opening and closing guides (810) protruding in the form of side branches on each side of the end, and

[0051] The cover portion (200) includes a mounting projection (230) that protrudes in a lateral direction at the point where the locking fixing member (220) is provided, and mounts the end of the cover portion (200) on the opening / closing guide (810).

[0052] According to the illustrated embodiment, the mounting projection (230) has a U-shaped cross-section in a form that surrounds the opening / closing guide (810). However, this is only one of the possible forms, and depending on the implementer, the mounting projection (230) and the form of the opening / closing guide (810) may be implemented in other forms having the same technical concept.

[0053] FIGS. 1 and 2 show a hair rod (1000) mounted on a heating rod (600) in a form where the mounting projection (230) is fitted into the opening / closing guide (810), and the cover portion (200) can be kept in an open state by the cover holder (800). In this state, after the user wraps hair around the body portion (100), the hair straightener body (2000) is gripped to bring the upper clamp portion (700) and the lower clamp portion (500) into close contact (i.e., closing operation), and the closing operation is linked to the cover portion (200), thereby fixing the hair by the cover portion (200).

[0054] As explained above, since the cover portion (200) has a gap movement parallel to the longitudinal direction of the body portion (100), after the closing operation of the cover portion (200), the cover portion (200) is pushed to the left of the illustration reference so that the locking fixing member (220) is fitted into the locking projection (120), thereby securing the hair.

[0055] Afterwards, the user can detach the hair rod (1000) from the hair iron body (2000) and attach a new hair rod (1000) to the hair iron body (2000) to continuously style the hair.

[0056] FIG. 6 is a perspective view of an electric ancient device implemented in a double-sided form as another embodiment of the present invention.

[0057] An electric hair iron (A') according to another embodiment of the present invention is an example in which the hair iron body (2000') and the hair rod (1000') are implemented symmetrically on both sides.

[0058] First, I will explain the hair rod (1000').

[0059] The hair rod (1000') is mounted on the hair straightener body (2000') and receives heat for hair styling. Additionally, the hair rod (1000') has a structure that maintains the hair in a wound form.

[0060] A hair rod (1000') according to the illustrated embodiment includes a body portion (100) and a pair of cover portions (200a, 200b).

[0061] The body portion (100) has a cylindrical shape as a part on which hair (not shown) is placed. The body portion (100) may be formed of a synthetic resin material, and may also be formed of a metal material such as aluminum for effective heat conduction from the heating rod (600).

[0062] A pair of cover portions (200a, 200b) each have a semicircular shape that wraps around one side and the opposite side of the body portion (100) so that the hair placed on the body portion (100) forms a wave or roll shape.

[0063] A pair of cover parts (200a, 200b) are each rotatably connected at one end of the body part (100). That is, the cover parts (200a, 200b) and the body part (100) form a three-pronged clamp shape through connection.

[0064] The part where the cover part (200a, 200b) and the body part (100) are rotatably joined is described as the hinge part (300).

[0065] The hinge portion (300) may simply be implemented in the form of a fixing pin that penetrates one end of the cover portion (200a, 200b) and one end of the body portion (100), or it may be implemented in a structure (not shown) in which rotation is linked to interlock the upper cover portion (200a) and the lower cover portion (200b) according to the illustration.

[0066] Each cover portion (200a, 200b) includes a locking fixing member (220) that is coupled to a locking projection (120) provided at the other end of the body portion (100) (i.e., the end opposite the hinge portion (300)) to maintain a closed state with respect to the body portion (100).

[0067] In FIG. 6, two stoppers (120) are arranged side by side, with the stopper located on the upper side fixing the upper cover part (200a) and the stopper located on the upper side fixing the lower cover part (200b).

[0068] For example, as shown in FIG. 7, a locking fixing member (220', 220) may be implemented so that the cover portions (200a, 200b) are fixed to each other.

[0069] Alternatively, as shown in FIG. 8, the cover portions (200a, 200b) may be provided with a locking fixing member (220) at one end of the cover portion to maintain a closed state relative to the body portion (100), and a locking projection (120) corresponding to the locking fixing member (200) may be provided at the other end of the cover portion. That is, the locking projection (120) may be positioned at the end of the lower cover portion (200b) and fixed to the locking fixing member (220) of the upper cover portion (200a).

[0070] However, the shape and structure of the illustrated catch (120) and catch fixing member (220) are merely examples for the sake of understanding, and may be modified into various shapes not illustrated for material properties and manufacturing convenience.

[0071] Next, we will describe the main body of the hair iron (2000').

[0072] The hair straightener body (2000') according to the present embodiment includes a main body part (900), a heating rod (600), an upper clamp part (700'), a lower clamp part (500'), and a cover holder (800a, 800b).

[0073] The main body (900) is a component that serves as the central axis of the hair straightener main body (2000') and includes a switch for turning the power on / off and a temperature control unit for controlling the temperature of the heating rod (600).

[0074] The heating rod (600) is in the form of an extension from the main body (900) and serves as a mounting bracket into which a hair rod (1000, 1000') is inserted. The heating rod (600) is equipped with a heating element inside and applies heat to the mounted hair rod (1000, 1000') to enable the setting of the hair shape by the hair rod (1000, 1000').

[0075] The heating rod (600) is attached to a length adjustment rod (910) extending from the main body (900), and the opening angle of the cover holder (800a, 800b) can be adjusted by adjusting the protruding length of the length adjustment rod (910).

[0076] The upper clamp part (700') is rotatably connected to the end of the main body part (900) (i.e., hinged) to form a clamp shape.

[0077] The lower clamp part (500') has a hinge connection shape that allows it to rotate at the end of the main body part (900) in a shape symmetrical to the upper clamp part (700').

[0078] A pair of cover holders (800a, 800b) are each connected to the ends of the upper clamp part (700') and the lower clamp part (500') by a hinge structure (P1) and have a shape that extends toward the heating rod (600).

[0079] A pair of cover holders (800a, 800b) link the opening and closing operation (i.e., gripping operation) by the upper clamp part (700') and the lower clamp part (500') to the hair rod (1000').

[0080] The ends adjacent to the main body (900) of a pair of cover holders (800a, 800b) are connected by springs (SP1, SP2) to the inner sides of the lower clamp part (500') and the upper clamp part (700') located opposite each, so that when the grip of the lower clamp part (500') and the upper clamp part (700') by the user is not formed, the pair of cover holders (800a, 800b) can be kept in an open state.

[0081] The end portion adjacent to the main body (900) of a pair of cover holders (800a, 800b) is fixed in a form that has a clearance for operation at the point where the heating rod (600) and the length adjustment rod (910) are connected via a hook structure (SP2). By adjusting the length adjustment rod (910), the opening angle of the cover holders (800a, 800b) can be finely adjusted according to the forward and backward movement of the heating rod (600).

[0082] According to the present embodiment, the opening angle of the cover holders (800a, 800b) can be widened compared to the embodiment of FIG. 1. Therefore, the user can wind the hair onto the hair rod (1000') more easily.

[0083] Figure 9 is a photograph of the actual electric archer shown in Figure 6. The hanging structure (SP2) is implemented in a form that doubles as a spring (SP1, SP2).

[0084] The cover holders (800a, 800b) each include opening and closing guides (510) protruding in the form of side branches on both sides of the end.

[0085] Each cover portion (200a, 200b) includes a mounting projection (230) that protrudes in the lateral direction of the end portion and mounts the end portion of the cover portion on the opening / closing guide (810). At this time, it is preferable that the mounting projection (230) has a U-shaped cross-section to surround the opening / closing guide (810).
