TECHNICAL FIELD [0001] The present invention relates to improving the steam cutoff property of a hair iron of V-shaped, hair-sandwiching type used for various perm treatments, where hairs are sandwiched between a pair of openable / closable heating plates that are attached on the opposing surfaces of the hair-sandwiching arms of the hair iron. [0002] The present invention also relates to a hair iron of V-shaped, hair-sandwiching type offering improved steam cutoff property with respect to one void space in the hair-sandwiching arm shielded by shielding members, by means of placing a heating plate with its base end tapered and then tight-fitting a gasket in the applicable tapered void. [0003] The present invention further relates to a hair iron of V-shaped, hair-sandwiching type fitted with a gasket for the purpose of improving the steam cutoff property of the connection area between one void space in the hair-sandwiching arm in which a heat-source plate and a heating plate are stored ...

Benefits of technology

[0007] The present invention was devised in light of the aforementioned circumstances and the object of the present invention is to provide a safe, easy-to-operate hair iron that eliminates the possibility of electrical damage. This hair iron also permits easy temperature adjustment because the temperature controller and temperature display can be stored in a void space in the V-shaped, hair-sandwiching arm that is shielded by shielding members, which in turn is made possible by changing the structure of the heating plate base supported by the shielding members in the V-shaped, hair-sandwiching arm and thereby improving the steam cutoff property of the shielded void space in the V-shaped, hair-sandwiching arm.

[0008] In order to achieve the aforementioned object, a gasket offering excellent heat resistance and elasticity is fitted between the shielding members and the bases, on the void space side, of the heating plates that are attached in a manner facing each other and maintained on the V-shaped, hair-sandwiching arms (each comprising a pair of right and left shielding members) so that the plates remain open in normal condition, and the gasket is secured using a taper shape provided at each base of the heating plate. This prevents high-temperature steam from seeping into the void space and thereby presents a hair iron of V-shaped, hair-sandwiching type wherein temperature-adjustable heat-source plates, temperature display and temperature controller are stored in the void spaces in the hair-sandwiching arms.

[0010] (1) A hair iron of V-shaped, hair-sandwiching type, comprising a pair of openable / closable hair-sandwiching arms that each store, in a void space shielded by a pair of right and left shielding members constituting each hair-sandwiching arm, a temperature-adjustable heat-source plate and a heating plate that contacts the heat-source plate and sandwich hairs when the arms are closed, wherein the hair-sandwiching arms are openably / closably connected on one end by a pivot so that the force of a spring provided at a bearing maintains the pair of openable / closable arms in open directions in a normal condition, and the heating plates are affixed in a manner facing each other; the hair iron characterized in that the bases, on the void space side, of the heating plate are tapered and a gasket is fitted in gaps formed by the tapers in order to improve the steam cutoff property of the void space and also facilitate disassembly and assembly.

[0012] As explained above, the hair iron of V-shaped, hair-sandwiching type proposed by the present invention comprises a pair of right and left shielding members, and the bases of each heating plate stored in the void space shielded by the shielding members are tapered in advance. In the process where the pair of shielding members are assembled and installed from both sides, the convex parts of the shielding members are engaged completely in the tapered voids along the tapered bases of the heating plate, thereby enhancing the airtightness of the void space and thereby improving the steam cutoff property. As a result, the hair iron proposed by the present invention prevents steam from seeping into the void space between the shielding members where the heating plate is attached, even when steam generates from the water content of the perm solution and other chemicals as a result of heating the heating plate during hair ironing. Consequently, this hair iron can completely cut off steam from the void space. Also, a heat-source plate, a temperature controller and a temperature display can also be stored in the void space of the V-shaped arm shielded by the pair of right and left shielding members, which allows the operator to adjust the temperature easily at his or her fingertips. Furthermore, such structure prevents the risks of fire caused by high-temperature steam seeping into the void space and contacting the heat-source plate. Moreover, the operator can easily adjust the temperature by looking at the temperature display near his / her operating hand. Also, simply connecting the pair of shielding members from both sides allows the gasket to align automatically along the tapered bases of the heating plate and completely fit the tapered voids, so the shielding members can be disassembled or assembled from right and left with ease.

Problems solved by technology

As explained above, conventional hair irons had the problem of high-temperature steam trapped along the periphery of the heating plates and eventually seeping into the void spaces shielded by shielding members via the gaps between the heating plate attached to the V-shaped, hair-sandwiching arm and the shielding members.

However, filling calking agent makes it difficult to disassemble the hair iron into component parts.

Screw-tightening a gasket permits easy assembly, but such attachment structure is vulnerable to large impact and exhibits poor durability.

When hairs are sandwiched between the heating plates during the perm, repeated pressurization of the shielding members by the heating plate affects the shielding property between the heating plate and shielding members.

This has sometimes led to the problem of high-temperature steam seeping into the void space along the shielding members in a V-shaped, hair-sandwiching arm and contacting the heat-source plate to cause the complex circuitry of the temperature controller to suffer electrical damage.

In addition to presenting the risks of fire resulting from such electrical damage, conventional hair irons had to have their temperature controller and temperature display installed away from the V-shaped, hair-sandwiching arms.
