An atomizer is provided for dispensing liquids into the air. In some implementations, a device is provided for generating atomized fluid specifically, but not exclusively, for production of small droplets of scented oil and other fluid-based fragrances, among other types of liquids. In some embodiments, the device comprises a tube-shaped element having a proximal opening and a distal opening, wherein media positioned inside the tube is forced out of the proximal opening via an aperture plate.

A handheld misting device has a housing having a dispensing window is arranged and configured to contain a sonic generator, a power source coupled to the sonic generator, a plurality of reservoirs, each containing a liquid, and a plurality of nozzles, each nozzle arranged and configured for removable coupling to the sonic generator. Each nozzle is associated with and in liquid communication with a single reservoir. The sonic generator includes a converter and an elongate horn having a proximal end coupled to the converter and a distal end, and the nozzle is removably coupled to the distal end of the horn. Thus, the device delivers the liquid through a delivery opening formed in the nozzle, and activating the sonic generator energizes the liquid in the nozzle to generate an aerosol plume that is delivered through the dispensing window.

The device for diffusing volatile substances, which comprises a container (1) to house a liquid containing the volatile substances, a capillary element (2) partially housed in said container (1), a perforated element (3) through which volatile substances are diffused, and a piezoelectric element (4) in contact with said perforated element (3) and in contact with the capillary element (2), said piezoelectric element (4) causing the vibration of said capillary element (2), wherein the diffusion device also comprises an elastic element (5) on which said piezoelectric element (4) is mounted, said elastic element (5) being attached to said container (1) or to a housing (6) that surrounds said container (1). Said elastic element allows the piezoelectric element to be perfectly centered with respect to said capillary element.
