Portable device for heating the air that enters the nose of a user

A portable device for heating air that enters a nose of a user, wherein the portable device is formed by an energy system and a support system;

• where said energy system comprises in turn an external source of energy, an electronic control board, an electrical resistance, a heat sink, a temperature sensor and a temperature control knob, the heat sink having a plurality of vertical grooves and a continuous annular lining around the heat sink as a thermal insulator, the plurality of vertical grooves extending from a lower face of the heat sink to an upper face of the heat sink, the plurality of vertical grooves allowing air to enter through the lower face and to come out through the upper face, wherein the electrical resistance and the temperature sensor are both housed inside the heat sink such that heat produced by the electrical resistance is transferrable to air within the grooves of the heat sink, which is inhalable through the nose of the user when coming out through the upper face of the heat sink;
• and wherein said support system comprises a plurality of couplings and a hose that connect the elements of the energy system together and at the same time allow the portable device to be fixed to the user.
