Abstract: A portable apparatus for generating vapor for a facial sauna includes a housing enclosing a vented liquid storage tank having an inlet for receiving liquid to be vaporized and an outlet. An electrically heated vapor generator is located in the housing and receives liquid from the tank outlet through an electrically operated diaphragm pump for producing vapor which is discharged from an vapor outlet in the housing. The housing includes an elastic wall portion immediately adjacent and confronting the diaphragm operating armature of the pump. The elastic housing portion is manually displaceable inwardly of the housing for displacement of the pump diaphragm by the armature to prime the pump. An adjustable control is provided for regulating the pumping rate of the pump. The vapor generator is provided with anti-sputter baffles to prevent liquid droplets from being discharged with the vapor.
