A humidifier comprises a liquid storing chamber provided in the lower portion of the casing. A nozzle is provided in the upper portion of the casing. An adaptor, provided in the upper portion of the casing, introduces compressed air and liquid into the nozzle. A liquid sucking pipe communicates with a liquid sucking opening of the adaptor and extends vertically downward to the vicinity of the bottom surface of the liquid storing chamber. A float is provided in the liquid storing chamber and is movable along the inner surface of the liquid storing chamber, depending on the amount of the liquid stored therein. A liquid cutoff lever is provided above the float and contacts the upper surface thereof. A liquid cutoff valve, of a liquid cutoff device mounted on the casing is operated by the liquid cutoff lever so that the capacity of the liquid to be controlled by the liquid cutoff valve is small, for example 30 cc.

Humidifier

A nozzle is disclosed which has a cylindrical nozzle main body. A nozzle tip of the nozzle comprises a plurality of members formed by dividing an approximately cylindrical member in the axial direction thereof and is accommodated in the interior of the nozzle main body. A spring is provided between a spring receiving section of the nozzle tip and a wall positioned on a forward side of the nozzle main body. At least one of a peripheral surface of a discharge section of the nozzle tip and an inner surface of a tip engaging opening of the nozzle main body is tapered. A self-cleaning operation is performed when the atomization pressure is reduced, because the spring urges the nozzle tip toward a rearward side of the nozzle main body.
