The hookah device (202) comprises a driver device (202) which controls the mist generator devices (201) to maximize the efficiency of mist generation by the mist generator devices (201) and optimize mist output from the hookah device (202).

A volatile material dispenser includes a base and a stand assembly that is coupled with the base. The base includes a fan and a battery therein. The stand assembly includes a platform, a stand that extends from the platform, and a manifold that extends from the stand. The volatile material dispenser also includes a shroud and an air deflector. The shroud is positioned on the base and defines a chimney. The air deflector is positioned between the shroud and the manifold. The air deflector is configured to direct air out of the chimney.

A piezoelectric dispenser includes a refill having a container having a neck and defining a fluid reservoir, a wick holder affixed to the neck, and a wick retained by the wick holder that has an upper end that is in communication with a piezoelectric assembly, the wick defining a longitudinal axis. The dispenser further includes a housing having a base and an overhanging cover that defines a fluid outlet and extends inward from the base at a shoulder, toward the longitudinal axis, the overhanging cover being disposed around and above the upper end of the wick and housing the piezoelectric assembly. The piezoelectric assembly includes a coil compression spring and the base is provided on a rear side of the refill with the left, right, and front sides being exposed to a surrounding environment after the refill has been coupled with the overhanging cover.

A volatile material dispenser comprises a base that houses a printed circuit board. The base includes at least one button and a plurality of visual indicators along a front portion. The volatile material dispenser further comprises a stand assembly that is coupled with the base. The stand assembly includes a platform defining a front portion and a rear portion, a stand that is disposed above and on the rear portion of the platform, a manifold that is disposed at an upper end of the stand and defines an outer side surface from which extends a plurality of radially spaced ribs, and a piezoelectric assembly disposed within the manifold. The volatile material dispenser further comprises a cover that is configured to be attachable to and detachable from the base. The cover defines a chimney that defines a longitudinal axis. The manifold includes a refill chassis.

Provided herein are an ultrasonic-based aerosol generation device, which is capable of reducing cartridge replacement costs and ensuring immediate aerosol generation, and a cartridge recognition method thereof. The ultrasonic-based aerosol generation device according to some embodiments of the present disclosure may include a liquid reservoir configured to store a liquid aerosol-forming substrate, a vibration element configured to provide ultrasonic vibrations to the stored liquid aerosol-forming substrate to form an aerosol, and a porous member which is disposed to be spaced apart from the vibration element and has a plurality of holes formed therein. Here, the liquid aerosol-forming substrate may be pushed in a direction toward the porous member due to ultrasonic vibrations of the vibration element, and the pushed liquid may be rapidly vaporized by passing through the plurality of holes. Accordingly, an aerosol can be generated immediately upon a puff.

A device or system is provided that provides olfactory stimuli, and includes a piezoelectric vibration device that is used to produce scents corresponding to actions performed in a VR or AR environment, or other application. In some implementations, a user interacts with one or more game elements within a game program being executed by a game engine, and responsive to the interaction, the game engine may communicate a series of commands that cause a piezoelectric device of the device to generate scents to be experienced by the user.
