According to an exemplary embodiment of the present invention, a floating-type humidifier includes a lower body which has a buoyancy space formed along an inner edge to float in water and has a water inlet formed so that water flows into a lower center; an upper body formed with a hollow tube communicable with the water inlet; and supporter formed in an elastically deformable closed curve, in which the supporter is in contact with an upper end of the lower body and a lower end of the upper body to couple the lower body and the upper body to each other.

A folding travel humidifier, comprising a humidifier main body and a water storage bag arranged on an upper part of the main body of the humidifier; the main body of the humidifier is provided with a power source, a control circuit board and the utility model An atomizer for generating a water mist during vibration; the atomizer is electrically connected to the control circuit board; the water storage bag includes a wave body disposed around the outer circumference of the humidifier main body, and can be folded and stored toward the bottom, and The inner side of the wave crest body is provided with a vent hole for outputting a water mist; the atomizer is located at an intermediate portion of the bottom of the water storage bag.

A method and apparatus for sterilizing medical instruments, including a device for controlling specific humidity, SH, of flow of a gas or gas mixture. The device includes a tank for storing a volume of water. The tank has an inflow port for receiving the gas or gas mixture, and an outflow port for allowing humidified gas or gas mixture at the required SH to exit the tank. The temperature of the water and/or the pressure of the supplied gas or gas mixture are controlled for the required SH.

Provided is a dual structure humidifier, and more particularly, a dual structure floating-type humidifier with a noise reduction function. The dual structure humidifier includes a water tank in which a fluid is contained, a floating body which floats in the fluid in the water tank and performs a humidification operation using an ultrasonic module provided therein, a blowing fan which introduces external air into the water tank and the floating body or discharges the air in the floating body to the outside, and a water tank case which is provided to form a predetermined separation distance from the water tank and surround an outer circumference of the water tank and has air intake ports formed at one side to communicate with the blowing fan and reduce noise generated inside the water tank.
