Abstract
A humidifier includes a first housing removably connected to a second housing that includes the majority of the electrical components of the humidifier. The first housing includes a first air inlet for accepting air; a first air outlet; a central chamber for holding water; a piezoelectric transducer installed in the central chamber for atomizing water; and a first electrical connector electrically connected to the piezoelectric transducer. The first housing is configured to discharge humidified air from the first air outlet. The second housing includes a second air outlet removably connectable to the first air inlet; a forced air source for forcing air out of the second air outlet; a second electrical connector configured to removably electrically connect to the first electrical connector; and an electric circuit electrically coupled to the forced air source for electrically powering the forced air source and electrically coupled to the second electrical connector for electrically powering the piezoelectric transducer.
