Patent ID: 8082929

Claim:
A hair iron comprising: upper and lower casings defining a grip portion and coupled to each other at a first end by an elastic coupler such that the casings in the side of a second end opposite to the first end are pivotable within a certain angular range about the first end; an upper heater block extending in a longitudinal direction of the upper casing and coupled on the second end of the upper casing which is not coupled with the lower casing; a lower heater block extending in a longitudinal direction of the lower casing and coupled on the second end of the lower casing which is not coupled with the upper casing, wherein the upper heater block has a semi-cylindrical heating section and a first heater attached to an inner part of the heating section, wherein the lower heater block has a concave heating section, a heater plate and a second heater attached to a surface of the heater plate which is not exposed outside, the heater plate being coupled onto a concave portion of the concave heating section by the medium of a heat-resistant elastic body, thereby defining the semi-cylindrical shape of the lower heater block, wherein the heater plate moves nearer towards the concave heating section or tilts (or pivots) about its longitudinal axis by the action of the elastic body so as to vary its position relative to the concave heating section.
