Abstract

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 electrical engine and electrical resistance; from the ionizing device, at least one cable emerges, which is duly insulated by a sheath, and at the end of the cable an active pole x is mounted.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 180 words
“IMPROVED HAIR DRIER” comprising a housing, inside which an electrical engine is mounted, which activates a rotor generating an axial air flow crossing the equipment and contacting a heating element represented by an electrical resistance, duly mounted in a spacing structure; the housing of the relevant hair drier further incorporates a gripping part from which an electrical cable emerges, thereby allowing to connect the hair drier with an electrical network, said gripping part further incorporating keys which control independently both activation of the electrical engine and also activation of the electrical resistance, the hair drier further comprising an ionizing device, which is essentially a high voltage source with a limited current; the ionizing device is connected with the drier by a conventional electrical circuit, it being activated simultaneously with the activation of the electrical engine, or further at the time of the conjoint activation of both electrical engine and the electrical resistance; from the ionizing device, at least one cable emerges, which is duly insulated by a sheath, and at an end of the cable an active pole is mounted.
Claim 2
Dependent Claim 180 words
“IMPROVED HAIR DRIER” comprising a housing, inside which an electrical engine is mounted, which activates a rotor generating an axial air flow crossing the equipment and contacting a heating element represented by an electrical resistance, duly mounted in a spacing structure; the housing of the relevant hair drier further incorporates a gripping part from which an electrical cable emerges, thereby allowing to connect the hair drier with an electrical network, said gripping part further incorporating keys which control independently both activation of the electrical engine and also activation of the electrical resistance, the hair drier further comprising an ionizing device, which is essentially a high voltage source with a limited current; the ionizing device is connected with the drier by a conventional electrical circuit, it being activated simultaneously with the activation of the electrical engine, or further at the time of the conjoint activation of both electrical engine and the electrical resistance; from the ionizing device, at least one cable emerges, which is duly insulated by a sheath, and at an end of the cable an active pole is mounted.
Claim 3
Dependent Claim 26 words
“IMPROVED HAIR DRIER” according to claim 1 , wherein the cable passes along a central region of the spacing structure where the electrical resistance is mounted.
Claim 4
Dependent Claim 27 words
“IMPROVED HAIR DRIER” according to claim 1 , wherein the active pole is configured by a needle-shaped element having an essentially tapered format, with a sharp-pointed end.
Claim 5
Dependent Claim 41 words
“IMPROVED HAIR DRIER” according to claim 3 , wherein the needle-shaped element configuring the active pole is positioned preferably near a previous end of the spacing structure, which location coincides with a point of highest air flow speed crossing the equipment.
Claim 6
Dependent Claim 19 words
“IMPROVED HAIR DRIER” according to claim 1 , wherein the relevant drier may incorporate two or more active poles.
Claim 7
Dependent Claim 25 words
“IMPROVED HAIR DRIER” according to claim 3 , wherein the needle-shaped element configuring the active pole includes a needle-shaped end directly mounted to the cable.
Claim 8
Dependent Claim 41 words
“IMPROVED HAIR DRIER” according to claim 1 , wherein the heating element includes a relatively vertical portion and a relatively horizontal portion traversing the relatively vertical portion and running substantially perpendicular thereto, the active pole being mounted on the heating element.
