A smoking device for aerosol-generation may comprise a device housing, a surface acoustic wave-atomizer (SAW-atomizer), a supply element, and a control system. The device housing may include a storage portion for an aerosol-forming substrate. The SAW-atomizer may include an atomization region, a first transducer, and/or a second transducer. The first transducer is configured to generate first surface acoustic waves that propagate along a surface of the SAW-atomizer. The supply element is arranged to supply the aerosol-forming substrate from the storage portion to the atomization region of the SAW-atomizer. The control system is configured to operate the SAW-atomizer to atomize the aerosol-forming substrate in the atomization region to generate an aerosol. A cartridge for such a smoking device and a method for generating an aerosol in a smoking system are also provided.

A device is disclosed for the preparation of nebulised droplets, for inhalation. The device has: a surface acoustic wave (SAW) transmission surface; a SAW transducer adapted to generate and propagate SAWs along the SAW transmission surface; and an array of cavities opening at the SAW transmission surface for containing a liquid. In operation, SAWs propagating along the SAW transmission surface interact with the liquid in the cavities to produce nebulised droplets of the liquid. Operation of the device results in a nebulised plume of droplets of average diameter in the range 1-5 μm.

A fluid dispenser (1) for dispensing a cosmetic composition (2) comprises a housing (3), a dispenser head (4), at least one first receptacle (16) being connectable to a first reservoir (5) comprising a first fluid (6), and at least one second receptacle (17) being connectable or connected to a second reservoir (7), the second reservoir (7) being configured to receive a second fluid (8). The fluid dispenser (1) further comprises a mixing area (18) being in fluid communication with the dispenser head (4), the first receptacle (16) and the second receptacle (17). The mixing area (18) is configured such, that the cosmetic composition (2) is generated when a dose of the first fluid (6) is mixed with the second fluid (8) within the mixing area (18).

A well support assembly for a fragrance dispenser includes an upper cover including a plurality of chambers, a well support engaged with the upper cover proximate to the plurality of chambers, and a plurality of wells engaged with the well support. Each of the plurality of wells extends into a respective one of the plurality of chambers and is configured to receive a fragrance therein.

Disclosed is an ultrasonic electronic cigarette atomizer. An atomizer shell, an atomization piece and a liquid guide structure are arranged in the atomizer shell. The liquid guide structure communicates with a liquid storage cavity in the atomizer shell. A heating body is arranged in the atomizer shell.

The heating body can quickly heat the tobacco tar to approach to its atomization temperature, and also can transfer a part of heat to the atomization piece, so that the atomization piece atomizes the tobacco tar quickly, shortening the atomization time.

Aeroponics apparatus is disclosed, which includes a grow bed tray having a base and at least two side-walls, the grow bed tray being able to hold a plant support at a position spaced from the base of the grow bed tray, and a nebulizer for nebulizing nutrient solution, the nebulizer located at the base of the grow bed tray and comprising an ultrasonic transducer and a holder for holding the ultrasonic transducer. Also disclosed is a method for crop production using the aeroponics apparatus by either flowing nutrient solution into the base of the grow bed tray to contact at least the roots of the crops or providing nutrient solution at the base of the grow bed tray and nebulizing the nutrient solution so that the nebulized nutrient solution contacts at least the roots of the crops.

Apparatus and associated methods are provided for digitally controlled powder deposition. The apparatus comprises a supply chamber configured to maintain a reservoir of powder in a fluidised state, and one or more dispenser elements. The supply chamber is further configured to direct a flow of the fluidised powder from the reservoir to an orifice, causing it to be dispensed from the orifice.
