Abstract
A liquid atomizer is constructed with a hollow shell-like top cover and a unitary molded main support which snaps into place inside the top cover and divides it into upper and lower regions. The main support includes formations for mounting, on its upper side, a printed circuit board assembly including an electrical oscillator, as well as a piezoelectric actuator and orifice plate pump assembly. The main support also includes formations for removably mounting, on its lower side, a battery and a liquid reservoir. An openable bottom cover closes the bottom of the device and allows access to the battery and to the liquid reservoir for replacement of these elements.
