An improvement on a humidifier includes a leakage prevention ring, and two opposite supporting plates. The leakage prevention ring has several ring-shaped portions, which define inner and outer concentric annular trenches. The concentric trenches are closely mounted onto an upper end of a vapor conduit, and a down-projecting annular protrusion lo of a vapor outlet disposed right above the conduit respectively. The supporting plates can pivot up and down, and are biased by torsion springs to hold a water-supplying bottle between them in an inverted vertical position, which is connected to a valve of the humidifier, so that the bottle can't tilt or shake to cause damage to the valve.
