Abrégé

The present invention relates to an apparatus and method for the low energy flash-like vaporization of liquids and the release of the resulting vaporized liquid into the atmosphere in the form of a visible plume, mist or cloud. Vaporization is occasioned in a geometrically small device capable of producing vaporized liquid that varies little in composition in comparison to the starting liquid feed to the device. The apparatus and method are primarily directed towards the treatment of small areas for residential air fragrancing, odor elimination, treatment of insects or pests, air sanitization, air and surface antibacterial or antimicrobial treatment, administration of personal pharmaceuticals or medicaments, as well as other ambient air or surface modification by way of gas, vapor or droplet distribution.

Abrégé

The present invention concerns capillary force vaporizers for use in vaporizing liquids and emitting pressurized vapors. In one embodiment, the inventive capillary force vaporizer includes a porous member, a heater component to convey heat to the porous member, and a vapor containment region. The porous member further includes a capillary network, a surface for receiving liquid and a vaporization area in which vapor is produced from the liquid. The vapor is collected and pressurized within the vapor containment region, which includes one or more openings for the release of vapor at a velocity greater than zero. Several different embodiments for capillary force vaporizers and systems comprising capillary force vaporizers are disclosed along with methods for their use.

Abrégé

Devices for generating a vapor jet from a source liquid comprise a capillary force vaporizer and a condensation controller. Generally, a capillary force vaporizer comprises a porous vaporizer having capillary-sized pores, an enclosure and a vapor egress orifice. The capillary force vaporizer forms a vapor jet from unpressurized liquid by heating the liquid to vaporization in a substantially confined volume. Vapor output from the liquid vaporization section enters the condensation controller, which may be configured to prevent the condensation of vapor or promote the controlled formation of fine liquid droplets, which are generally less than about 100 μm diameter. The condensation controller may be maintained at a predetermined temperature. Alternatively, ambient air or other external gases may be introduced into the condensation controller. Various architectures for the vapor condensation controller are disclosed.
