Description

Hair iron having outer cover {hair iron having external cover}

The present invention relates to a hair iron used for hair care, and more particularly, to a hair iron of a form in which a removable cover is coupled to the body.

In general, the hair iron is a device for forming a variety of hairstyles by applying heat to the hair, it is widely used as a device for setting the hair in a general beauty salon or home. Since the hair iron has a built-in heater, the heater heats the hair while applying pressure to maintain a constant shape.

Such a hair iron is usually composed of two parts (upper and lower case) to sandwich the hair, and at least one of them is attached with heating means for heating the hair, and the heating means is directly attached to the hair. The heating plate (hereinafter referred to as a heater plate) and a heating unit (heater) for supplying heat to the heater plate by self-heating in many cases. In addition, the heater plate or the heat generating part is often mounted on the case while being installed in the holder so as not to directly contact the case. Since the holder, the heat generating unit, and the heater plate may be treated as a single component by being coupled to each other with respect to the case, these may be collectively referred to as a heater block.

The hair iron can be used to give the hair a large curvature, to curl the hair with a rather small curvature, to straighten the straight hair, or to process a curled hair with a small curvature. All is possible.

However, the suitable form of the hair iron may also vary with each processing form. Therefore, a hair iron may be manufactured in a form suitable for processing, and the hair iron may be divided into a straight perm and a curling process.

A curling hair iron having a rod or a cylindrical hot plate and a pressing part for holding the hair together with the hot plate roughly forms two legs of a tong is widely used for processing the curvature of the hot plate. The end of the hair is fixed between the rod-shaped hot plate and the pressing part. In this state, the hair fixed at the end is wound around the hot plate and the pressing part a few times. Is formed into a round shape by receiving heat from the hot plate.

On the side that is in contact with each other on the lower case, similar to the two legs of the tongs, an approximately flat heater plate is installed. On the back side of the heater plate, the case is covered with a case and the hair is flat in a flat hair iron. Is placed between the two heater plates facing each other, and the hair iron is simply pulled to the outer end of the hair, or the hair is rotated slightly as it is to be pulled to form a straight hair or a large curvature wave.

By the way, the curling hair iron above the hot plate is exposed to the outside, the user has a lot of worry about the hand, and when you release the hair iron for a while, the surrounding objects are likely to damage the hot plate. Therefore, in order to solve such a problem, the protective cover which covers all or part of a hotplate may be used.

On the other hand, since the heater plate is exposed only on the inner surface facing each other and the other side is wrapped by the case, the flat hair iron is hardly damaged by the user while using the hand or surrounding the hair iron. In other words, the case serves as a protective cover of the curling hair iron.

By the way, the hair iron can be used in a normal home, and it is not appropriate for the general user used at home to have all types of hair irons in order to process hair in various forms in consideration of cost and storage space. Usually, the average user will use one or two hair irons. Therefore, the curling hair iron may be used for wave processing or straight hair processing, and there may be a need to curl the flat hair iron.

However, two heater plates facing each other of the flat hair iron hold a portion of hair therebetween, and in this state, curling molding by rotating the hair iron to wrap the hair around and heat it is a case surrounding the outside of the heater plate. Since the material is usually made of synthetic resin, there is a side that is not suitable for heat transfer.

In addition, the part of the hair holding part of the flat hair iron has a flat shape that forms the outside of the two leg parts while the two legs of the forceps are in close contact, and it is difficult to form round curls when the hair is wound around it. In many cases, depending on the material, when the hair is heated from the hair iron after the hair is heated, the case may not be easily slipped from the hair, thereby making it difficult to process.

The present invention is to reduce the difficulty of curling using a flat hair iron, a hair iron that can be easily and efficiently curling by adding a detachable cover to the existing flat hair iron It aims to provide.

The present invention for achieving the above object, the upper case and the lower case having the heater installation portion and the handle portion in the longitudinal direction, respectively, the one end of the handle side is hinged to each other, the heater installation portion of the upper case and the lower case In the hair iron having a heater plate provided on the inner side facing each other,

The heater mounting portion is characterized in that it has a removable metal cover surrounding the upper case and the lower case on the outer side rather than the inner side on which the heater plate is installed.

In the present invention, a cover groove may be formed in the upper and lower cases or holders so that both side ends of the metallic cover can be inserted and fixed in the upper and lower cases or holders so as to easily attach and detach the metallic cover. In this case, the metal cover may be coupled to the case while being fitted toward the hinged end along the groove formed in the upper, lower case, or the groove formed in the holder from the end opposite to the hinged end.

In the present invention, the metal cover may be formed in a semicircular shape so that the two metal covers of the upper case and the lower case form a circle as a whole when the upper case and the lower case are in close contact.

In the present invention, the heater plate may be installed in the heater installation portion of the upper case and the lower case while being mounted on the holder, the holder or the upper case and the lower case of the heater plate on both sides in the width direction of the heater plate A plurality of hot air holes may be provided along the length direction. In this case, the metallic cover for curl processing of the present invention may be installed to flow hot air from the hot air hole along the cover surface which comes into contact with the hair.

When the metal cover is installed to allow hot air to flow along the cover surface where the hair comes into contact with the hair, when the heater plate is viewed from the front, the hot air hole provided on the side thereof is covered by the side end of the metal cover, and the hot air is at the side end of the metal cover. It can not be discharged to the front by the front, while turning along the inner side of the semi-circular wall surface of the metal cover can act to form a hairstyle while transferring heat through the cover to the hair surrounding the outer side of the semi-circular wall.

According to the present invention, in a flat hair iron having heater plates installed only on inner surfaces of the upper and lower cases facing each other, a metal cover for easily detachable curl processing is further provided, so that not only straight and wave processing but also curl processing with small curvature are easy. Can be done easily.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

In the upper and lower cases, the heater block is installed at the heater installation part, the inner cover and the circuit are installed, and the part that the user holds by hand will be called a handle part.

Looking at the coupling portion rotatably coupled to a predetermined angle of the two cases, one end of the upper case (101a) support 104a and the mounting portion (111a) formed with a coupling through hole 105a at the center of the side has a predetermined interval They are formed side by side, and the support 104b and the settled portion 111b having a through hole 105b formed at the center of the side surface of the lower case 101b to correspond to the support 104a and the settled portion 111a are fixed. It is formed side by side at intervals.

After coupling the upper case 101a and the lower case 101b with a spring 107 in which the brush 110 is embedded between the supports 104a and 104b and the settled portion, the rotating shaft 106 is passed through the through holes 105a and 105b. By inserting the screw 109 to both ends of the rotary shaft 106 after insertion into the brush 110 through the upper and lower parts by the elasticity of the spring 107 and the external pressure applied to the upper and lower cases 101a and 101b. The cases 101a and 101b may rotate at an angle about the rotation axis 106.

In the upper and lower cases, the heater block is installed on the inner surface of the heater mounting portion facing each other, and the metal covers 120a and 120b of the present invention are installed on the outer side. The metal covers 120a and 120b are generally formed of aluminum or stainless steel, and may be anodized or other coating on the surface thereof. Roughly speaking, it has a semicylindrical shape formed by splitting the cylinder in half in the longitudinal direction.

Referring to FIG. 2 together, both ends in the width direction or the circumferential direction of the semi-cylinder are coupled while holding both ends in the width direction of the heater mounting portion of the upper and lower cases. On the inner surface of the heater installation portion of the upper and lower cases, an installation groove 230 may be disposed on both sides of the metal cover 220a and 220b on both outer sides of the heater block based on the width direction of the heater block and guided. .

Accordingly, in FIG. 2, the metal cover 220 is provided with one end of the metal cover 220b from the heater installation side side end of the lower case along the installation groove 230 such that the hair iron is fitted in the longitudinal direction or the longitudinal direction of the metal cover as shown by arrow A. FIG. Can be combined. Alternatively, the outer surface of the upper case formed to be convex outward in FIG. 2 and the inner surface of the metal cover 220a face each other, and then the thickness direction (upper and lower case overlaps as shown by arrow B of the hair iron 200). When the pressure is applied to the metal cover 220a from the outside in the direction that is arranged so that the upper and lower cases and the metal cover can be combined so that the inner surface of the metal cover surrounds the outer surface of the upper case while both ends of the width direction of the metal cover are opened. have.

Both ends of the metal cover in the width direction may be bent inward and overlapped for a predetermined period as shown in FIG. 1. In this case, the overlapped portion 121 is enhanced in mechanical strength to reduce the risk of plastic deformation or breakage when combined with the main body or during normal storage, and can increase the durability of the metal cover. In addition, since the sharp cutout portions at both ends of the circumferential direction are not exposed, the user can use the product more safely even if the finishing process is not performed much.

In this embodiment, when the hair to be trimmed is curled, the heater installation unit directly touches the outer side of the upper and lower cases to not wind the hair iron case, but the hair iron is wound while being in contact with the outer surface of the metal cover. Easier to slip from hair irons. Particularly, if the metal cover is close to the semicircle in the cross section perpendicular to the length, the outer surfaces of the two semicircular metal covers of the upper and lower cases form a nearly round shape, so that there is no angular portion during curl processing, so the hair easily slips. The hair can be easier to clean. In addition, since the metal cover is generally made of synthetic resin, compared to the upper and lower cases, the metal cover has high thermal conductivity, so that the heat is evenly distributed through the metal cover and the hair that contacts the metal cover can be processed at an even temperature.

Figure 3 is a perspective view of the body portion 300 of the hair iron showing another embodiment of the present invention.

Compared with a conventional hair iron, in this embodiment, the heater plate 330 and the holder 310 of the upper and lower case 301 are installed while configuring the heater block, and the holder 310 A plurality of hot air holes 311 or air holes are provided along the longitudinal direction of the hair iron. Through this hole, the air introduced from the outside is exhausted through the blower inside the hair iron. Air flowing in the process is heated while being in contact with the heater block and is discharged through the air hole in the hot air state to heat the hair around the heater plate 330 to help in molding. Since the embodiment of the main body 300 of the hair iron is already known in the field of hair iron, a detailed description thereof will be omitted.

4 and 5 are perspective views showing a state in which the metal cover 320 of the present invention is installed in the hair iron main body portion of FIG. 3 and a cross-sectional view showing a section cut perpendicularly to the hair iron length direction in the heater installation portion.

4 and 5, both ends of the circumferential or widthwise direction of the metal cover 320 are coupled to installation grooves provided at both ends of the widthwise direction of the holder 310 of the heater block. The heater block is provided with a heater 350 and a silicon grease layer 340. The holder 310 of the heater block is installed in the upper and lower cases 301 while the lower portion thereof is supported by an elastic body such as silicone rubber 360. The hot air coming out through the air hole of the heater block installation portion of the upper and lower cases 301 in the state where the metal cover 320 is coupled is pivoted on the inner surface of the metal cover as shown by the arrow of FIG. 5 by the metal cover 320. The metal cover 320 is discharged to the outside through the gap between the two ends in the longitudinal direction. If there is no metal cover, the temperature difference is large in the place where hot air is emitted from both sides of the heater plate 330 in the width direction, and the hair is easily damaged by heat in the place where the temperature is high during hair processing, and in the place where the temperature is low. Because of the poor shaping of the hair, it was not easy to decide on what basis and for what time.

However, when the metal cover is provided as in the present embodiment, since the metal cover is made of a fast heat transfer metal, the temperature is uniformly distributed by the hot air turning around the inner surface of the metal cover. Therefore, heat can be transferred at an even temperature to the hair wound on the outer surface of the metal cover, and the hair contacting over the entire metal cover surface can be processed evenly, thereby making it easy to adjust the processing time or degree.
