The basic principle of hair irons is: hair is mainly composed of protein, and the skeletal structure of protein determines the shape of hair; there are chemical bonds such as disulfide bonds, hydrogen bonds and salt bonds in proteins. Yes; these chemical bonds are to maintain the structure and shape of the hair. The straight hair is wound around the heating member and heated, the amount of heat of the heating member expands the hair, and the chemical bond in the protein is broken, so that the structure of the straight hair becomes modifiable. At that time, as soon as the straight hair is wound around the curved surface, it curls and becomes curly hair. When the curly hair is cooled, chemical bonds in the protein are formed again, keeping the hair in the curly state. However, existing hair irons have the following disadvantages: 1) High temperatures can harm the health of the hair and cause it to lose moisture; to improve curling efficiency of the hair iron, The operating temperature of the heating member usually reaches as high as 200 ° C.

Since one opening 8 is opened at the first proximal end 2, the hair 33 can be put into the first elongated groove 6 very easily. Of course, the first opening 8 of the first elongated groove 6 may be provided in the side wall of the main body 1.

  1 and 2, the hair iron further includes a first movable arm 7 movably provided in the first inner space 4; the groove wall of the first elongated groove 6 and The first movable arm 7 is provided with a heating member for heating the hair 33.

  Specifically, referring to FIG. 1, the main body 1 is further provided with a connecting member, the connecting member has a movable mechanism, the movable mechanism is a hinge mechanism 13, and the first movable arm 7 is It is mutually connected with the main body 1 through the hinge mechanism 13; in this embodiment, the connecting member is provided in the first inner space 4.

  Specifically, in the present embodiment, referring to FIG. 1, the first elongated groove 6 extends from the first opening 8 toward the first far end 3, and in the first elongated groove 6, A bottom portion 9 is formed at a portion that is away from the far end 3 and approaches the first near end; the hinge mechanism 13 is provided between the bottom portion 9 and the first far end 3; The axis is perpendicular to the extending direction of the first elongated groove 6; the first movable arm 7 rotates about the axis of the hinge mechanism 13 as a pivot, and forms the groove wall and the sandwiching portion of the first elongated groove 6 To do. The pinching portion is used to pinch the hair 33.

  Further, in this embodiment, the heating member includes a heating surface 12 provided on the first movable arm 7 and a heating unit 28 that is connected to the heating surface 12 and raises the temperature of the heating surface 12. The side wall on the first near end 2 side of the main body 1 is a main body outer wall 5 used for cooling the hair 33;

  When the hair 33 heated by the body outer wall 5 is cooled, the shape of the cooled hair 33 is determined. Normally, when the heating member is activated, the temperature of the heating surface 12 is higher than the temperature of the main body outer wall 5; when the temperature of the heating surface 12 is higher than 180 ° C., the difference between the temperature of the main body outer wall 5 and the temperature of the heating surface 12 is It is at least 90 ° C., or the temperature of the main body outer wall 5 is 50% lower than the temperature of the heating surface 12.
