Fixing structure for heating module of hair dryer

A fixing structure for fixing a heating module of a hair dryer, comprising:

• a heat-emitting ceramic, comprising a first through hole configured at a center thereof, wherein a heat-emitting film is coated on a surface of the heat-emitting ceramic, and silver paste films are coated on an upper end surface and a lower end surface of the heat-emitting ceramic to form silver paste electrodes thereon respectively, wherein a power supply is provided to the heat-emitting film via the silver paste electrodes, so as to allow the heat-emitting ceramic to generate heat;
• a voltage step-down ceramic, comprising a second through hole configured at a center of the voltage step-down ceramic and positionally corresponding to the first through hole of the heat-emitting ceramic, and a plurality of passing holes uniformly distributed around the second through hole, wherein silver paste films are respectively coated on an upper end surface and a lower end surface of the voltage step-down ceramic to configure silver paste electrodes thereon respectively, wherein the voltage step-down ceramic is disposed in contact with one of the upper end surface and the lower end surface of the heat-emitting ceramic, wherein the first through hole of the heat-emitting ceramic and the second through hole of the voltage step-down ceramic are aligned with each other, and silver paste electrodes on the contacted end surfaces of the heat-emitting ceramic and the voltage step-down ceramic are electrically connected with each other;
• a ceramic sleeve, assembled through the first through hole and the second through hole, wherein the ceramic sleeve comprises a third through hole, and the third through hole is positioned in parallel with the first through hole and the second through hole;
• and
• a conductive metal bolt, assembled in the third through hole of the ceramic sleeve, for fixing the heat-emitting ceramic and the voltage step-down ceramic onto a supporting frame seat of a motor and a fan of the hair dryer.
