Device and method for indicating the amount of water contained in a humidifier water bottle

摘要

A humidifier includes a reservoir for containing water, a wick wettable by water contained in the reservoir and a humidifier bottle for supplying water to the reservoir. The bottle is pivotally situated in the humidifier and a translating member is responsive to the angular movement of the humidifier bottle. The translating member includes a visual indicator thereon to indicate the amount of water contained in the bottle. A biasing member cooperates with the translating member to situate the humidifier bottle in a first angular position in response to the bottle being empty, such that the bottle is displaced from the first angular position within the receptacle when the bottle contains water. The amount of angular displacement of the bottle is a function of the amount of water in the bottle. A light source may be provided to illuminate the display window in response to movement of the translating member.
