The device has one or more arms (10, 12), articulatably tied to one another, which incorporate a duct (22) connected on the one end to a pressurized vapour generator (18), while on the opposite end said duct engages in a vaporization group, placed at the upper end of arm (12), composed by a container (30), at whose base a metal plate (40) is attached which surmounts a resistor (42). The container (30) has, on the front opposite to the engagement point of the duct (22), a nozzle (38) for letting flow out the vapour which has passed through the heated chamber (30'). The vaporization group incorporates a chamber (46), closed by a removable cap (34), communicating with said chamber (30'). Near nozzle (38) a quartz ozonizing lamp (52) is preferably placed. The vaporization group and lamp (52) are housed in a box integral with arm (12).
