ABSTRACT:
What is disclosed is a hand-held steam dispensing apparatus having a removable water reservoir, the reservoir containing a diaphragm dividing the reservoir into a large chamber and a small chamber wherein water from the large chamber may flow quickly into the small chamber, but water in the small chamber is restricted from flowing into the large chamber, a spring biased bellows pump with two one-way valves for allowing water to be pumped out of the bellows into a heating enclosure when the bellows is compressed and for allowing water to fill the bellows when the bellows expands. The heating chamber is coated to cause the water to form a thin film whereupon the water is heated to form hot water vapor which then expands through a barrel into a perforated tube. The water vapor passes out of the perforations to provide hot water vapor to a user's hair.
