Description

This invention relates to an electric heating rod, a hanger device, and a perm module including the same, and more particularly to an electric heating rod and hanger device to which a terminal separation structure is applied, and a perm module including the same. Generally, methods for perming hair (also called "curling") are classified into three types: the perming method, which involves applying a perming solution to the hair; the setting method, which creates waves by directly applying heat to the hair without using a perming solution; and the mixed method, which involves applying a perming solution to the hair and then applying heat to perm it. In this case, to perm the hair by applying heat, an electric heating rod (Korean Patent Publication No. 10-0405257, published November 12, 2003) is used, which is connected to the perming device and generates heat when electricity is applied. However, since the electrical terminals of existing heating rods are located on only one side of the rod body, a problem arose where one end of the heating rod was further heated, placing a load on the electrical terminals.

The following describes specific embodiments of the present invention in detail with reference to the drawings. However, the concept of the present invention is not limited to the embodiments presented. Those skilled in the art who understand the concept of the present invention could easily propose other, albeit less advanced, inventions or other embodiments within the scope of the present invention by adding, changing, or deleting other components within the same scope of the concept; these, too, can be considered within the scope of the present invention. Figure 1 is an overall perspective view of a perm module according to one embodiment of the present invention. As shown in Figure 1, a perm module 10 according to one embodiment of the present invention is a perm module that transmits heat to hair using electrical energy transmitted from the perm main body for perm treatment. It may include a hanger device 200 connected to the perm main body, and an electric heating rod 100 that is detachable from the hanger device 200 and generates heat based on electrical energy transmitted from the hanger device 200 while remaining connected to the hanger device 200. A perm device refers to a device used to support hair and release heat during treatments such as perms, straightening, and coloring. The perm device may include a support section (not shown) that stands upright on the ground, a perm body section (not shown) supported by the support section so as to be separated from the ground, a heating rod 100 that forms a region where hair is wrapped and releases heat by electrical energy, and a plurality of hanger devices 200 to which the heating rod 100 is detached and which are electrically connected to the perm body section to transmit electrical energy to the heating rod 100. The perm stylist wraps the hair around a 100mm electric rod, then applies hair dye or perm solution to the hair. Subsequently, the hanger device 200 is connected to the heating rod 100 so that electrical energy is transmitted to the heating rod 100 via the perm machine body and the hanger device 200. As a result, heat is released from the heating rod 100 and applied to the hair. The structure of the electric heating rod 100 and the hanger device 200 will be described in detail below. Figure 2 is an exploded perspective view of the heating rod of a perm module according to one embodiment of the present invention, and Figure 3 is an enlarged view of portion A in Figure 2. As shown in Figures 2 and 3, the electric heating rod 100 according to one embodiment of the present invention may include a housing portion 110 having an outer surface that provides a region for wrapping hair around it and an inner housing space that is a predetermined space; a heating portion 120 disposed in the housing space and releasing heat through transmitted electrical energy; a temperature sensor portion 130 disposed in the housing space and sensing the temperature at least one point in the housing spac
