Description

  The present invention relates to a hair iron, and more particularly, to a hair iron having a structure that facilitates straightening and curling of hair with a single hair iron.

  In general, a hair iron is widely used as a device for forming various hairstyles by applying heat to hair, and as a device for setting hair in a general beauty salon or at home.

  In such a hair iron, a portion that is touched by hair in a high temperature state is constituted by a flat plate shape, or a curved surface such as a side surface of a cylinder or a rod. In general, it is known that a flat plate type is suitable for straight hair processing (straight processing), and a curved surface is suitable for bending hair processing (curl processing).

  Usually, in order to simplify hair processing with a hair iron and efficiently transfer heat, a means for holding the hair so that the hair is in close contact with the high-temperature portion is provided.

  Therefore, in most plate-type hair irons, a pair of upper and lower cases can be rotated at a certain angle around the hinge axis at one end in the longitudinal direction of the lower case through elements such as hinges and springs. Combine cases. In addition, a heater plate that transfers heat to the hair is provided on the inner side of the lower case (the surface where the upper and lower cases face each other) on the side away from the hinge in the longitudinal direction, and the hair is sandwiched between the two heater plates. The hair is processed in the state.

  An inner cover is provided on the inner surface side of the lower case on the side close to the hinge in such a hair iron. The inner cover is provided so as to cover the lead wires and the adjustment circuit in a state where the lead wire and the adjustment circuit for connecting the electric wire introduced from the outside and the electric device such as the heater provided on the heater plate side are built in the upper case. .

  Also, in most plate-type hair irons, a heater that directly generates heat and transmits it to the heater plate is provided on the back surface of the heater plate that comes into contact with the hair. A method of attaching the holder to the case is used in a state where these are provided in a holder made of heat-resistant synthetic resin so as not to touch.

  The cylindrical curling iron body, which is configured so that the rod-shaped or cylindrical part touches the hair so as to be suitable for the curving process, when viewed from the longitudinal direction, the grip part held by the hand at the time of processing, and the hair touching the hair Can be divided into a rod-shaped or cylindrical heating section. In order to adhere and fix the hair to the heating unit, the main body has a gripping part coupled to the main body using a hinge and a spring. When the grip side portion of the grip portion is pushed or released with a part of the hand, the remaining portion of the grip portion is brought into close contact with or separated from the heating portion by the lever principle.

  In the plate-type hair iron, a flat plate-shaped heater plate is provided on the inner surface of the lower case, and the heater plate applies heat to the hair. Therefore, the plate-type hair iron is not suitable for curving hair. In other words, if the user bends the hair with a plate to bend the hair, it is difficult to obtain a natural hair curve due to the form of contact between the hair and the plate, and the edge portions at both ends of the plate in the width direction. Since the hair concentrates and bends at an acute angle only, it is difficult to process the hair so that it naturally slides on the plate surface, and there is a problem that the hair hurts or falls out and the scalp feels pain.

  On the other hand, when a hair iron having a cylindrical heating part is used for straight hair processing, since the heating part forms a curved surface, the portion where the hair and the heating part are in contact with each other is extremely small, and heating is difficult to be performed efficiently.

  Therefore, it has been difficult or problematic to apply straight hair processing or curving processing to hair with a single hair iron. However, it is expensive to purchase and use a plurality of these hair irons in a normal home, occupying a storage space, and it is not easy to carry various hair irons together when carrying them.

  The present invention is to solve the above-mentioned problems of conventional hair irons, and to provide a hair iron having a structure that can easily care for various forms of hair such as straight hair processing and curved hair processing. With the goal.

  An object of the present invention is to provide a hair iron having a structure that can efficiently care for various forms of hair without inconvenience in use.

A tilt operation (rotation operation) is possible around the center.

  In the present invention, one of the upper heater block and the lower heater block may have a corresponding surface that is wider than the other and is recessed so as to cover the other corresponding expanded surface.

  In the present invention, a cap made of heat-resistant and heat-insulating material is provided at the other end of the heater block, one side of which is coupled to the lower case, and a part of these caps is held by the user's hand.

  FIG. 1 is a perspective view illustrating a hair iron according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of the hair iron according to an embodiment of the present invention as viewed from another angle.

  The grip portion has an aspect similar to that of a conventional plate-type hair iron. In addition to forming the grip portion, one end in the longitudinal direction (a) of the lower case (10, 20) is joined by a hinge and a spring provided around the hinge. Although not shown on the back side, a power line connected to an external power source is drawn out.

  The upper and lower cases (10, 20) are made of synthetic resin in the form of a groove cylinder. The recessed groove portion of the groove cylinder embodies a lead wire for supplying current flowing from the power line to the heaters (33, 43) in the heater block in charge of heating the hair, and an adjustment circuit for adjusting the current PCB (51, 61) is provided. If necessary, a blower (not shown) can be provided in this part. The upper and lower cases are finished by covering the openings of the groove portions with the covers (53, 63) in a state where the conductors and PCB are mounted in the groove portions of the case. A radial switch (67) or the like for adjusting a temperature controller or the like provided on the PCB (51, 61) can be provided on the cover part so that at least a part thereof is exposed.

  The upper and lower cases (10, 20) are in the longitudinal direction (a) in the previous stage (opposite to the power line input side). Combined to extend the length.

  FIG. 3 is a cross-sectional view showing a cross section of the upper and lower heater blocks partially cut perpendicular to the longitudinal direction in order to show the configuration of the upper and lower heater blocks.

  The upper heater block coupled to the upper case (10) is a semi-cylindrical heating unit, and includes a integrally formed metal cylinder (31) having a semicircular cross section and a heater (33) closely contacting the inside of the metal cylinder. It is prepared for. The heater (33) is configured to cut off the current when a fuse or PTC (Positive thermal coefficient) adheres to it and the hair iron overheats. The cross section perpendicular to the longitudinal direction of the metal cylinder (31) has a substantially semicircular circumferential portion (313) and a diameter line portion (315) corresponding to the semicircular diameter line, and the diameter line portion (315) is completely It is not a straight line but a curved line with a large radius of curvature, and has a protruding shape that bulges outward. The intersecting portion of the circumferential portion (313) and the diameter line portion (315) is connected with a natural curve so that no angle is generated, and this portion is a thick portion of the metal tube (31), and a groove is formed in that portion. (311) is formed. The groove (311) is formed through the entire length of the metal tube (31) and connects both ends in the longitudinal direction (a).

  Synthetic resin caps (38, 39) having heat insulation and heat resistance are provided at both ends in the longitudinal direction (a) of the metal tube (31). Here, heat resistance and heat insulation are used in a general and general concept in this technical field, and such materials are used in a range that is already widely known in the synthetic resin field. For example, synthetic resin caps (38, 39) must be able to withstand the highest temperature of hair processing with a hair iron, for example, higher than 200 ° C or 220 ° C, and process while transferring heat by touching the hair Compared to the heater block, the heat transfer property is small, and it must be at a level that does not cause burns when touched by hand.

  Of the synthetic resin caps (38, 39), the cap (39) provided at the end where the upper heater block is coupled to the upper case (10) is coupled to the upper case (10). (55) is combined. Here, the metal tube (31), the caps (38, 39) at both ends, and the coupling member (55) are fastened together by a long bolt (not shown) penetrating in the groove formed in each of them. The

  In addition to the groove opened in the longitudinal direction (a), the coupling member (55) has a groove opened in the vertical thickness direction (c), and the upper case (10) in the form of a groove cylinder through the groove, the upper part It can be combined with a cover (53) that covers the opening side surface of the groove cylinder forming the case (10). That is, the groove of the coupling member (55), the groove of the upper case (10) and the groove of the cover (53) can be aligned, and these elements can be coupled by a bolt (not shown) fitted into the groove.

  The coupling structure of the lower case (20) and the lower heater block is also similar to the coupling structure of the upper case and the upper heater block. However, the lower heater block has a different structure from the upper heater block. That is, the lower heater block closes the opening of the groove cylinder (groove: grooved tube heating part: 41) and the groove cylinder (41) compared to the upper heater block having a semicircular metal tube (31). A heater plate (47). A heater (43) is provided on the back side of the surface exposed to the outside of the heater plate (47), and protrudes from the width direction (b) both ends of the heater plate (47) to the outside in the width direction of the skirt portion curved to the back side. The protrusion (471) is fixed by being sandwiched between the grooves of the silicone pad (45). The silicone pad (45) is sandwiched between corresponding grooves in the groove cylinder (41) of the lower heater block. The silicone pad (45) has heat resistance capable of withstanding the maximum temperature of the heater plate (47).

  For this reason, when the heater plate (47) receives an external pressure while closing the opening of the groove cylinder (41), the elasticity of the silicone pad (45) is fixed within a certain range toward the center of the groove cylinder (41). When it is pushed in or when one end in the width direction (b) is pushed, the other jumps up slightly, and when the other is pushed in, a tilt operation in which one end tilts becomes possible.

  On the other hand, the width of the lower heater block is configured to be slightly larger than the width of the upper heater block. When the heater plate (47) is not a perfect plane, it can be covered with a swelled form of the diameter line portion (315) indicated by the cross-sectional shape of the metal cylinder (31) of the upper heater block. Make a concave curved surface. That is, when the heater plate (47) is viewed from a cross section cut by a plane perpendicular to the longitudinal direction (a), it forms a curved curve that is recessed when viewed from the outside because of its large radius of curvature. However, both ends of the heater plate (47) in the width direction (b) continue to form a curved surface with the downward skirt (side surface) (not the angled corner) so that the flow of the hair will not be disturbed when sliding the hair. Configured. The width of the lower heater block is configured to be slightly larger than the width of the upper heater block, and the lower heater block is formed so as to partially cover the upper heater block at the portions that touch each other.

  A part of the groove cylinder (41) has a thick part (wall body), and a groove (411) which is long in the longitudinal direction and connects both ends in the longitudinal direction of the groove cylinder (41) is formed in this part. The groove (411) functions like a groove (311) formed long in the metal cylinder (31) of the upper heater block. Therefore, the synthetic resin caps (48, 49) at both ends in the longitudinal direction of the lower heater block and the coupling member (65) are coupled as in the case of the upper heater block (illustrated through the groove in the longitudinal direction). The fastening member (65) is joined to the lower case (20) and the cover (63) in the same way (the grooves are aligned in the vertical direction and sandwiched between the grooves). (A method for connecting these elements with bolts not shown).

  The heater (43) that forms the lower heater block can also be provided with a PTC (positive thermal coefficient) and fuse to prevent overheating. For example, referring to FIG. 4, a specific embodiment will be described.A heater block, which is a heat generating structure, is exposed to the outside and is in contact with hair, and an inner surface of the heater plate (the interior of the lower case is A heater (43) provided on the visible side) that generates heat to transfer heat, and a fuse that disconnects the power supply when an overheating occurs while in contact with the heater, the heater plate and the heater and fuse are tightly coupled A fuse fixing spring (46) is provided.

  The fuse (44) is the maximum temperature at which the heat generated by the heater (43) is used.For example, when the temperature exceeds 200 ° C or 220 ° C, the internal conductor is cut by heat and the fuse (44) The current flowing through the heater (43) that is electrically connected to is interrupted.

  The fuse fixing spring (46) is made of a steel plate having elasticity, and is a square-shaped rectangular frame that is partially bent at both ends in the longitudinal direction, sides in the width direction, and inner sides, and is double-bent. The heater, the heater plate and the fuse are physically coupled so as to be in close contact with each other by a spring action.

  Although not shown separately, a viscous silicone grease layer can be further used so that heat generated from the heater is uniformly transmitted between the heater and the heater plate to the heater plate. Usually, the heater plate 47, the groove cylinder 41 and the metal cylinder 31 are used by applying a coating such as ceramic coating or Teflon (registered trademark) to a metal such as aluminum or stainless steel.

  On the other hand, the upper case is provided with a lock switch (including 57 and locking part (571)) so that the approaching state is maintained even if the hand is released with the upper case and the lower case approaching. The lower case (20) is provided with a groove (631) at a position corresponding to (57) .When the lock switch (57) is moved, the locking portion (571) is locked to the groove (631) of the lower case. It is to be released.

  Since the configuration of one end where the upper and lower cases (10, 20) are coupled to each other so as to be capable of rotational operation within a certain range is normal, an example will be schematically described with reference to FIG. The part that can be coupled is constituted by a hinge structure. The upper and lower cases (10, 20) are provided with grooves (13, 23) that are penetrated by the hinge shaft (73), and a spring (75) is provided around the hinge shaft (73). When the upper case and the lower case (10, 20) are pushed toward each other by applying force by hand, the heater blocks of the upper and lower cases approach each other and transfer heat while holding the hair between them. . When the hand is weakened, the upper and lower cases are returned to the open state when the lock switch (57) is not engaged.

(Example)
Considering the usage method for the hair iron in the embodiment having the structure and form as described above, the hair is sandwiched between the upper and lower heater blocks at the time of straight hair processing as in the case of using the conventional plate-type hair iron. It starts to move in the hair direction.

  On the other hand, at the time of curving, the hair can be processed by other methods depending on the degree of curvature of the desired hair. For example, the hair is sandwiched between the upper and lower heater blocks, and the hair iron is slid so that the heater plate (47) of the hair iron has an angle with the hair, or the metal tube ( 31) The hair can be slid on the surface of the metal tube while winding the hair around and pulling it slowly. In addition, when the upper and lower cases are brought into close contact with the lock switch (57), the upper and lower heater blocks are brought into close contact with each other to form one large cylinder, which is not accurate, and the hair around the cylinders. The hair can be slid while being in contact with the curved surface of the lower heater block.

  At this time, since the metal tube (31) of the upper heater block is also excellent in heat conductivity of the metal other than the diameter line portion (315) to which the heater (33) is in close contact, it is used as a heating part for hair shaping. be able to. Further, the groove tube (groove tube type heating unit: 41) of the lower heater block is not provided with the heater (43), but the radiant heat and partial contact portion of the heater (43) provided on the heater plate (47) are not provided. Since it is heated by receiving the conduction heat from the heater plate through the wire, it can be used for hair shaping.

  The hair and the hair iron heater plate (47) have an angle with the hair sandwiched between the upper and lower heater blocks, and when sliding the hair, the width direction of the heater plate (b) both ends are curved, Since the heater plate is elastically moved by an elastic body such as a silicone pad (45) fixing the heater plate (47), the hair can be easily slid. Therefore, the problem that hair is damaged between the upper and lower heater blocks and the hair is damaged or pain in the scalp is reduced.

  Holding a hair iron with one hand while holding the hair in place can be an inconvenient task, even if the hair iron is light, because it must be applied to grip the hair. . On the other hand, in the conventional plate-type hair iron, only the heater plate (47) surface is exposed, and the entire area around the heater plate (47) is covered with a synthetic resin case, so the opposite side is provided with a hinge in the longitudinal direction. Since the other hand can hold the outer edge of the case and pull the hair with both hands, such a problem is not serious.

  However, in the present invention, since the heater block is not covered with the case and is generally exposed, there is no case part to be grasped with the other hand. Therefore, the caps (38, 48) are coupled to the heater block so that the end opposite to the end provided with the hinge can be grasped with the other hand. In addition, the cap prevents the outer surface of the metal tube (31) of the upper heater block and the groove tube (41) of the lower heater block from directly touching the floor when the hair iron is placed on the floor. ) And the groove cylinder (41) are preferably formed with a slightly larger outer diameter so as to form a step with the outer surface, or have ribs protruding outward on the periphery. In addition, the caps (38, 48) are provided with tips (381) protruding in the longitudinal direction so that they can be easily grasped by the other hand other than the hand grasping the grip part, for convenience when processing hair with both hands. 481).

  Although the present invention has been described in detail only for the specific embodiments described above, it will be apparent to those skilled in the art that various modifications and alterations are possible within the scope of the technical idea of the present invention. Of course, it belongs to the scope of claims for utility model registration to which amendments are attached.
