  • Patent number: 4634839
    Abstract: A forced air drying device for supplying filtered warm air for drying small areas, such as, for example, in dentistry or orthodontics, for drying of the teeth or gums prior to work thereon, includes a hand held forced air unit, such as a hair dryer, provided with a motor driven fan directing a stream of air over an electric heating element and through an outlet opening toward the area to be dried. A detachable nozzle has a first end mounted over the outlet opening and a second end with a reduced cross-sectional area for directing a concentrated stream of heated air to the area to be dried. The nozzle is provided with exhaust vents between the first and second ends thereof to prevent overheating of the motor due to a build-up of pressure resulting from the reduced cross-sectional area of the nozzle second end. An air deflector is provided adjacent each exhaust vent for directing escaping air away from the second and end of the nozzle.
