In a V-shaped hair pinching type hair iron, usually, both of a pair of heat plates facing each other are controlled at an appropriate temperature, and the hair coated with the perm solution is held between heat plates and heated. A heat plate, a heat source plate for heating this heat plate, and a hand-operated switch for temperature switching and a temperature controller are stored in the space of the V-shaped hair holding arm formed by the shielding member. Things are also known. However, in this type, the heating temperature of the heat plate is set in the range of 100 to L70 ° C as described above by adjusting the temperature controller by operating the hand switch for switching the temperature. Bring to temperature and sandwich hair between heat plates. When the hair is sandwiched, moisture such as the perm solution and chemicals applied to the hair evaporates instantaneously, generating high-temperature steam, which is discharged to all sides of the heat plate. High-temperature steam is trapped in the heat plate, and the high-temperature steam penetrates into the space of the V-shaped hair holding arm shielded by the shielding member through the gap of the shielding portion of the V-shaped grip body. There was a problem that high-temperature steam could cause electrical failures in control-related devices such as temperature switching switches, temperature controllers, and temperature indicators.Therefore, the above-mentioned control-related devices had to be placed at a position away from the hair-clamping arm. . For this reason Even if the temperature is adjusted with a hand switch arranged on the hair-clamping arm, the actual display temperature must be arranged at a position away from the V-shaped hair-clamping arm every time the temperature is switched. It was very troublesome for the perm practitioner to confirm. Disclosure of the invention

 As described above, in order to solve the problem that high-temperature steam is trapped around the heat plate and penetrates into the space shielded by the shield member through the gap between the heat plate and the shield member of the V-shaped hair-clamping arm. It has also been proposed to increase the vapor barrier properties by screwing the packing between the heat plate and the shielding member, filling it with a caulking agent, or bonding it. However, it is not easy to disassemble by means of filling with a caulking agent, and if the packing is screwed so that it can be easily disassembled, it will receive a large impact and poor durability, and the hair between the heat plates during perm treatment When the heat plate is repeatedly pressed against the shielding member due to pinching, the insulation between the heat plate and the shielding member is not sufficiently maintained, and high-temperature steam is evacuated to the V-shaped hair holding arm. And in contact with the heat source plate, causing electrical disturbance to the temperature controller in complex circuits. In addition, there is a risk that fire may be caused due to electrical failure. As described above, there is a problem that a temperature controller and a temperature indicator must be installed at a position away from the V-shaped hair holding arm. . The present invention was devised in view of the above circumstances, and devised a structure of a base portion of a heat plate supported by a shielding member of a V-shaped hair-clamping arm, and designed the V-shaped hair shielded by the shielding member. By improving the steam barrier property of the space of the holding arm, it is possible to store a temperature controller and a temperature indicator in the space of the V-shaped hair holding arm that is shielded by the shielding member, and display the temperature. An object of the present invention is to provide a curling iron that is easy to see, can easily adjust the temperature as a result, has no fear of causing an electric failure, is safe, and can be easily operated.

In order to achieve the above object, a V-shaped hair-clamping arm composed of a pair of left and right shielding members is provided with a heat plate attached to an opposite surface of the V-shaped hair-clamping arm which is kept open at all times. A high heat-resistant elastic packing is installed between the base on the side of the unit and the shielding member, and the packing is firmly installed using the taper provided at the base of the heat plate, so that the high-temperature steam The present invention provides a V-shaped hair-clamping type hair-eye opening in which a heat-regulating plate, a temperature indicator and a temperature controller are stored in the space of the hair-clamping arm while preventing infiltration of the hair-clamping arm. .

 That is, the hair iron of the present invention is characterized by the following basic configuration.

 (1) A heat source plate whose temperature can be adjusted and a heat plate that is in contact with it and holds the hair when closed One end of the hair-clamping arm is connected to be openable and closable by a shaft, and the pair of arms that are always openable and closable are mutually opened by the bias of a panel provided in a bearing portion. In a V-shaped hair-clamping type hair iron in which the heat plates are fixed to face each other, a taper is provided at the base of the heat plate on the space side, and the heat plate is formed by the taper. A hair iron characterized in that a packing that fits into the formed gap improves steam blocking properties of the space and facilitates disassembly and assembly.

 (2) One side of the hair holding arm, which houses the heat source plate and the heat plate, which is shielded by the shielding member, and is shielded by the shielding member of the hair holding arm. The hair flap according to (1), characterized in that the packing is arranged in a connection area with the other space to improve the steam barrier property of both the spaces.

 (3) A temperature controller and / or a temperature indicator are arranged in the space on one side containing the heat source plate and the heat plate or in the space on the other side. ) Or the curling iron according to (2).

A taper is provided on the base of the heat plate, and in the process of attaching the pair of shields together from both sides, the projection of the shield is tapered to the base of the heat plate. By completely fitting the tapered space along the gap, the sealing performance of the space is enhanced, thereby improving the steam blocking performance. As a result, the curling iron according to the present invention can be used in the space of the shielding member to which the heat plate is attached even if steam derived from moisture such as a perm solution or a chemical solution is generated by heating the heat plate during the ironing operation. It is possible to completely achieve vapor barrier properties without vapor infiltration. In addition, the heat source plate, temperature controller, and temperature indicator can be stored in the V-shaped arm that is shielded by the pair of left and right shielding members, so that the temperature can be easily adjusted at hand during treatment. . In addition, high-temperature steam penetrates into the space and comes into contact with the heat source plate to prevent the danger of fire, and the temperature can be easily adjusted while looking at the temperature indicator at hand. In addition, by fitting the pair of shielding members from both sides, the packing automatically fits the taper of the heat plate base and is completely fitted into the taper gap. The assembling operation for adjusting the shielding member from the left and right can be easily performed.

 The material of the packing that is installed between the heat plate and the base of the shielding member must have heat resistance that can withstand a temperature of more than one hundred and ten degrees, and it may come in contact with the vapor of the permanent liquid generated during treatment.

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Fig. 1 shows the heat plate of the V-shaped hair iron of the present invention and the packing attached to it. Fig. 2 shows the side view of the heat plate fitted with packing. Fig. 3 shows the cross section of the heat plate fitted with packing. (Cross-sectional view in the direction of the arrow in FIG. 2), FIG. 4 shows a state before the heat plate with the packing is supported on the iron body, and FIG. 5 shows a state after the packing is completely fitted to the iron body. FIG. 6 is a side view of a hair-clamping arm constituting the hair-eye opening of the present invention. FIG. 7 is a cross-sectional view taken along line BB of FIG. 6, and FIG. 8 is a conventional V-shaped hair-clamping arm type hair. FIG. 9 is a perspective view of an iron, and FIG. 9 is a cross-sectional view of a conventional V-shaped hair-clamping arm in a state where a heat plate is supported. In a conventional V-shaped hair-clamping arm type hair iron, as shown in Fig. 8, heat is applied by a sealing member 204 whose surface is covered by a protective sheet 211. G is held open and closed by a shaft 208 of a drip portion 206 at one end of a hair-clamping arm 200 supporting the arm 201, and the arm is actuated by the bias of a spring 211 provided on the bearing. Can be maintained in the opening direction, and the temperature can be changed by the temperature switching hand switch 220. However, the temperature controller and the temperature indicator (not shown) of the heat source plate cannot be stored in the void 218 formed by the hair-clamping arm 207 because the void has poor steam blocking performance. , They had to be placed far away. For this reason, even if the temperature was switched by the hand switch 220, it was troublesome to see the remote temperature indicator adjusted by the temperature controller to check the actual temperature. Fig. 9 is a cross-sectional view showing a state in which the heat plate is supported by the hair eye opening of the conventional V-shaped hair-clamping arm type. It is mounted on the base 203 of the heat plate 201 provided on the side. When mounting the packing 202, a pair of right and left shielding members 204 are accurately aligned from the left and right by the joining portion 216, and then the screws 222 are firmly attached to the heat plate 201. This mounting means can be filled with a caulking agent or bonded without using screws. In any case, when such a packing 202 is mounted, a position change occurs due to an impact or a long-term use, and a gap is generated between the shielding member 204 and the heat plate 203. There is a problem that high-pressure steam infiltrates the void portion 218 during treatment, and if a temperature controller or a temperature indicator is arranged in this void portion, there is a problem that an electrical failure occurs as described above. As shown in FIGS. 1 and 2, the hair eye opening of the present invention is provided with a packing 102 in advance on the heat plate base 103 of the heat plate 101 which comes into contact with the hair of the hair holding arm 107. (Fig. 2 shows the packing with the packing 102 attached, and Fig. 3 shows the A-A cross section of Fig. 2). The heat source plate 115 has a force S whose temperature can be adjusted by the temperature controller 113, and the base 103 of the heat plate 101 adjacent thereto is provided with a taper 105, and the formed taper is formed. Packing 102 is mounted in the gap 1 19.

The hair iron of the V-shaped hair holding arm of the present invention comprises a pair of openable and closable hair holding arms 107. To form the hair holding arm, a pair of left and right shields is required. It is necessary to reliably support the heat plate 101 by a combination of shielding members. The heat plate 101 adjacent to the heat source plate 115 is provided with a packing 102 in advance as shown in FIG. 3, and the heat plate 101 with the packing is mounted on the left and right sides. The heat plate 101 is securely supported by bringing the pair of shielding members 104 close to each other from both directions, and fixing the mating portions 116 of the two at appropriate locations with screws or the like. The combination operation of the pair of left and right shielding members 104 from both directions is performed as shown in Fig. 4 by approaching from the left and right to the center (in the direction of the left and right arrows in Fig. 4) so as to form a cavity 1 18 I do. When the shielding member 104 is brought close to the center from both directions, the convex portion 117 of the inner wall of the shielding member is moved in the center (inward direction) along the tapered surface 105 of the heat plate base 103. ), And fits into the tapered space 1 19 to work to seal. The heat plate moves in the direction of the joining portion 116 of the shielding member 104 (in the direction of the downward arrow in FIG. 4). Due to the movement of the shielding member protrusion 1 17, the packing 102 is strongly pressed left and right and up and down against the heat plate 101, and as a result, is shielded by the tapered gap 1 19 as shown in FIG. The protrusions 117 of the member are completely fitted, and the packing 102 is firmly attached to the shielding member 104, so that the steam barrier property is remarkably improved.

 FIG. 6 shows the length of one (upper part) of a pair of (upper and lower in the figure) hair holding arms 107 in which the heat plate 101 constitutes the V-shaped hair iron body of the present invention. It is sectional drawing of a direction. The hair-clamping arm 107 has a hair heat plate 101 firmly supported in the space 1 118 shielded by the shielding member 104, and the end of the drip portion 106 of the arm is a shaft. A pair of openable and closable arms are always maintained in the opening direction by the bias of a panel provided on the bearing portion, and the heat plates are connected to each other by the opening of the heat plate. They are supported face-to-face, and hold the hair when heated. The hair-clamping arm 107 has an appropriate protective sheet, a fixing portion 110 and a temperature display portion 114.

As described above, the V-shaped hair-clamping arm type hair iron of the present invention enables the V-shaped drip 106 of the pair of hair-clamping arms 107 that can be opened and closed to be rotated by the shaft 108. This panel is connected, and the urging of this panel causes the V-shaped When the arm 107 is closed, the heat plate 101 is parallel, and the surfaces are in close contact with each other to hold the hair.

 On the arm 107 of the V-shaped grip 106, a heat plate 115 is arranged on the back of the heat plate 101 (opposite the hair contact surface), and the temperature switching switch 120 Accordingly, the adjacent heat plate 101 is heated by the heat source plate 115 whose temperature has been adjusted by the temperature controller 113, and the temperature is indicated by a temperature display section 114.

 The V-shaped hair-clamping arm type hair iron of the present invention comprises a pair of shielding members 104 in which a pair of left and right shielding members 104 are combined from the left and right as shown in the direction of the arrow in FIG. A space for accommodating the heat source plate 115 and the heat plate 101 and a space for the drip 106 are formed by the pair of shielding members. In FIG. 6, the temperature controller 113 is disposed in the cavity on the drip side. However, in the present invention, the tightness of the packing improves the steam barrier property. It is also possible to arrange them in the empty space 1 18.

 In addition, a pair of shields in a connection area between the two spaces, in order to further improve the steam blocking performance of the space where the heat source plate and the heat plate 101 are housed and the space on the grip side. It is effective to dispose the second packing 109 on the joining portion 116 of the member 104. That is, as shown in FIG. 7 which is a cross section taken along the line BB of FIG. 6, by arranging the second packing 109, high-temperature steam around the heat plate 101 is cut off, and the heat source plate and It is possible to completely achieve the steam barrier property between the space where the heat plate is stored and the space on the grip side.

The method of using the hair eye opening of the present invention is the same as that of a conventional V-shaped hair-clamping arm type hair iron. That is, a predetermined amount of hair is sandwiched between the heat plates 101 by operating the V-shaped grip 106 while applying the perm solution to the hair and heating the heat plate 101 to a predetermined temperature. At this time, the perm solution applied to the hair evaporates, generating high-temperature steam. The steam is discharged to the four sides from between the heat plates 101, but when the pair of left and right shielding members 104 are fitted from the left and right, the packing 102 is formed by the heat plate base 103 and the projections of the shielding members 110. 7 along taper 1 0 5 The heat source plate contained in the cavity on the drip side or the heat plate side is completely fitted into the tapered space and firmly mounted, and the formed space has perfect steam barrier properties. 15 and the temperature controller 113 can operate safely and stably. Industrial applicability
