Patent ID: 8147771

Claim:
A sterilizing material supply apparatus comprising: a mist generation unit including: a propagation fluid holding unit for holding a fluid through which ultrasonic vibration generated by an ultrasonic vibrator attached to a bottom of said holding unit propagates; and a receptacle for holding a hydrogen peroxide solution which is a raw material for sterilizing material, the receptacle being attached onto the propagation fluid holding unit in such a manner as to cover an upper opening of the propagation fluid holding unit, and a bottom of the receptacle projecting toward the ultrasonic vibrator; and a vaporizing unit configured to heat and vaporize the hydrogen peroxide solution atomized by said mist generation unit wherein said vaporizing unit is installed upright above said mist generation unit, wherein a lower opening of said vaporizing unit communicates with the receptacle, said vaporizing unit including: a carrier gas supply port into which a carrier gas carrying the hydrogen peroxide solution atomized thereby flows through a lower side face of said vaporizing unit; a heating pipe, disposed on top of said mist generating unit, having a hydrogen peroxide supply port for supplying hydrogen peroxide, together with the carrier gas, to the exterior; and a heater disposed inside the heating pipe, wherein the hydrogen peroxide solution atomized by said mist generation unit is fed to said vaporizing unit using the carrier gas, and a hydrogen peroxide gas vaporized by said vaporizing unit, together with the carrier gas is supplied to the exterior.
