Abstract: A resistive element applied to heating equipment significantly increases the efficiency and savings in heating equipment such as hair drying equipment and other similar equipment. A resistive element has at least one flat and aligned profile resistive element mounted in a wave-shaped format. At least one support structure with four radial vanes is mounted and houses, aside from the resistive element units, the respective connection terminals, a thermostat, and required electrical wires.

Abstract: A stamped resistive element for use in electrical equipment, manufacturing process of stamped resistive element and apparatus equipped with stamped resistive element are provided. The stamped resistive element is produced from a stamping process and is intended to be used in replacement of conventional helical electrical resistances, whether in hair dryers and similar equipment or in other types of heating equipment. The stamped resistive element is produced as a blank from a metal sheet presenting a known resistive coefficient.

Abstract: “COLOR AND HARD ANODIZING PROCESS FOR APPLICATION ON METAL PLATES OF HAIR STRAIGHTENING AND MODELING MANUAL EQUIPMENT”, refers to the present invention for improvement applied in hard and color anodization process, especially used in metallic elements of equipment normally employed to straighten and modeling hairs, also traditionally known as “hair straightener”, “board” or “straightening plate” and it can be optionally applied also in other type of equipment of same kind used to produce curly hair.

Abstract: “IMPROVED HAIR DRIER” including a housing, inside which an electrical engine is mounted, which activates a rotor generating an axial air flow crossing the equipment and contacting the heating element represented by an electrical resistance, duly mounted in a spacing structures; the housing of the relevant hair drier further incorporates a gripping part from which the electrical cable emerges, thereby allowing to connect the equipment with the electrical network, the gripping part further incorporating keys which control independently both the activation of the electrical engine and also the activation of the electrical resistance, the relevant hair drier is characterized for incorporating an ionizing device, which essentially is a high voltage source with a limited current; the ionizing device is connected with the conventional electrical circuit of the equipment, it being activated simultaneously with the activation of the electrical engine, or further at the time of the conjoint activation of both electrica

Abstract: “MANUAL ELECTRICAL EQUIPMENT FOR HAIR STRAIGHTENING”, wherein each one of the heating plates of the referred equipment has a respective resistance, wherein the equipment characterized by the fact that each one of the resistances is controlled by a thermostat with differentiated temperature; in an alternative variant, the equipment incorporates in substitution of electrical resistances, PTC type thermistors.
